Definitions

  • the present invention relates to vices for the locking of items being worked on, and in particular regards improvements to modular vices.
  • the ram In each vice manufacture the ram has two longitudinal and transversal continuous slots on the lower surface which cross each other and are necessary for the fitting of the vice onto a support plane.
  • Holes with a constant distance between their centers are at least formed in the longitudinal slot to act as anchorage means of the vice.
  • the presence of said slots reduces the size of the face of the ram and weakens its section therefore resulting in that the ram is locked it can bend along its axle negatively affecting the good functioning and accuracy of the vice until movements of the mobile carriage along the ran become impossible.
  • the ram therefore the vice, can only be fitted to support planes with tee slots whilst it cannot be fitted and anchored to prismatic supports, so-called cubes, or to plates bearing a grid of holes.
  • Another aim of the present invention is to completely eliminate the above mentioned inconveniences and disadvantages of the known vices on one hand and to supply a simpler and more economical embodiment of a vice ram which is of universal use on the other hand.
  • the ram therefore the vice, will indifferently be fitted to support planes with grooves or tee slots as well to all prismatic supports and/or plates bearing grids of holes with preset and standardized distances between the centers.
  • the here proposed vice is essentially made up from a ram (11), a fixed jaw holder (12) and a mobile carriage jaw holder (13). Where necessary, the vice can be anchored to a rotating base (14) from the inside of the ram (11) without the use of brackets therefore leaving the vice cleaner and without further parts which could get in the way of the locking of the item.
  • the ram (11) is at least slightly wider than the fixed and mobile haw holder (12,13). Threaded holes (15) are formed in both sides of the ram (11) for a double funtion. In the first place said holes (15) make up as many anchorage points for a lateral accuracy stop (16) with centesimal repeatability which is rectified for the items to be positioned and locked in the vice. An item stop can thus be used even when the items are of particular shapes or of large dimensions. In the second place said lateral holes (15) immediately offer the possibility of anchoring the vice on one side at an angle of 90° on any type of tool or support plane without the need of adjustments. This is also due to the fact that the jaws are narrower than the ram and therefore their use is not hindered when the vice is placed on one side.
  • the ram (11) is fitted with verticle millings or grooves (17) near the ends of both its sides which allow for an accurate and secure coupling of two or more rams aligned in order to form a longer vice or for the connecting of added modules to the ram of a vice.
  • Such an aligned connection can be carried out by placing the rams (11) one behind the other (Fig.4) or one opposite the other, head to head, (Fig. 5) therefore without the need of a further more expensive fixed double jaw.
  • a first block (18) has fixed teeth (18a) designed to be inserted in the verticle grooves (17) on one side of the rams; the other block (19) has one fixed tooth (19a) and a mobile tooth (19b) which can be adjusted and blocked by a screw (20).
  • the mobile tooth (19b) has two oblique sides (Fig. 6) and sets in an oblique slots (21) formed in the coupling block (19).
  • This coupling and the possibility of adjusting it due to the mobile tooth in an oblique plane, ensures the perfect alignement of the vice rams and the absolute certainty of the blocking in order to prevent the connected rams from moving away from each other during the blocking, or worse still during the machining of the items between the jaws.
  • the lateral millings or slots (17) can also be used with another lateral coupling block with a pitch which is equal to the opening of the vice in order to prepare a longer vice by making use of two rams, but with the same strength of one.
  • the ram (11) also has (Figs. 12, 13) a row of datum holes (22) and another row of anchorage holes (22a). All the holes (22,22a) are through holes and in a perpendicular direction to the base of the ram.
  • the datum holes (22) are all of a predetermined diametre, for example of 16 mm with finishing (F7) and are aligned on two orthogonal directions, more precisely on the center line of the longitudinal guide (11′) of the ram (11) and transversally to it.
  • the anchorage holes (22a) are also aligned on the center line of the guide (11′), are placed between the datum holes (22) and each one has two areas of a different diametre, for example one lower area of a smaller diametre towards the base (Fig. 3) and an area of a larger diametre towards the guide (11′).
  • Both the datum holes (22) and the anchorage holes (22a) have a different distance between the centres as well as being modular or multiple of a datum level which permits the application and fixing of the ram and, with it, of the vice to prismatic supports (cubes) or plates with grids of holes with predetermined distance between the centres as well as to grooved planes or plates.
  • Both types of locks (116, 118) obviously have a diametre and finishing level which is equal to that of the datum holes (22) and each one has a peripheral annular seal (119) for its forced insertion into the hole to which it has to be applied.
  • the anchorage holes (22a) have screws (not shown) inserted in them in order to anchor the ram, thus the vice, onto the desired support.
  • the sides of the longitudinal guide (11) for the mobile carriage (13) are hollowed out (Fig. 13) in order to facilitate manufacture and to limit the finishing process up to only the surfaces (11 ⁇ ) against which the carriage beats when blocked.
  • Possible added modules which can contribute to the lengthening of a vice or to form a ram complete with a vice by themselves will have the same characteristics of the ram (11) described above, in particular with regards to the lateral vertical millings or grooves for the aligned coupling and the differentiated center line holes for the anchorage onto prismatic supports or planes with grids of holes.
  • the coupling between the added modules can also be carried out with attachment blocks with multiple teeth (19′), (Fig. 6a), in order to obtain a total lengthening and to reach the maximum opening without creating blind areas where the resulting vice cannot block.
  • Such lateral attachments do not require to have space recovered for the teeth seeing that the verticle grooves (17) can be rectified.
  • both the fixed one (12) and the mobile carriage (13) are fitted on the top with at least a pair of holes (23) each which are defined by a cylindrical part with a smooth surface (23a) and by a threaded part at the bottom (23b), (Fig. 3).
  • Said holes (23a, 23b) are used for anchoring onto the jaw holders (12, 13) and to perfectly align elements, tools or special jaws at the same time with only two hardened and ground precision screws which are available on the market.
  • the thread (23b) of said holes (23) never works by cutting but only by traction.
  • the holes (23) can be clogged by brass screw plugs (24) when they are not needed in order to protect them against the penetration of chips and can be fitted with seals to protect them against the penetration of liquids which could lead to rusting.
  • the mobile carriage (13) is guided on the ram (11) in the guide (11′) between two shoulders fitted with positioning and stopping notches (11a).
  • the carriage (13) is controlled by a screw (24) which rotates in a sleeve (26) and is engaged in a threaded hole (25) defined by a nut (27′) fixed to the carriage itself through a pin (27 ⁇ ).
  • the sleeve is axially guided, with the possibility of rotating, in a slot (28) formed in the carriage (13) and has an internal end that rests against a collar (25a) which is integral to the screw (25) through an anti-friction element.
  • the external end of the sleeve (26) has a flange (26a) designed to interact with the notch (11a) of the ram (11), the flange also having two notches (26b) which permit the axial sliding of the sleeve when aligned to the shoulders of the ram.
  • control screw (25) does not push the head against a side of the carriage (13) but interacts with the thread of the nut (27 ⁇ ) always remaining protected inside the carriage and by the sleeve (26) against accidental knocks and the clogging of chips.
  • the flange (26a) of the sleeve (26) acts as a position clutch and is fitted with a safety bolt (29) able to guillotine insert itself between the shoulders of the ram (11) when the clutch flange is coupled to the stop notches (11a).
  • the carriage, the screw and the sleeve with the bolt make up a single unit without any element which sticks out.
  • the clutch flange (26a) is not anchored to the base of the guide for the carriage but to the notches (11a), thus without the danger of being badly positioned because of possible chips present in the ram.
  • the vice therefore works even if encumbered by chips on the inside.
  • the safety bolt indicates the correct positioning and prevents accidental uncoupling.
  • the opening and closing conditions are shown in Fig. 7 and 10 of the drawing and can be defined by a spring stop (26′).
  • the mobile carriage (13) has a very long guide and has a gib (13′) on its base extended on the side of the guide of the sleeve (26) of the screw which also constitutes a safety stop for the control screw.
  • the long guide and the gib configurated in this way give embodiment a much more accurate and stable coupling of the ram-carriage in parity to slack than in known manufactures.
  • the vice can be assembled on a rotating base (14), (Fig. 11, 11a) made up from three rings which have a graduated scale for the indication of the rotation and having holes for datum pins and holes for anchorage screws.
  • protection blocks (30), for example in nylon, are placed in the guide for the carriage in order to have the maximum cleaness and reliability. These blocks couple to each other and to the carriage thus preventing the penetration of chips into said guide.
