Abstract

The universal quick-adjust insert for precise positioning of mounted shafts in a pallet consists of four holders, each of which is located in one corner of the pallet frame and is provided with two adjusting screws, on which pairs of support rods are fixed parallel to each other, while on the two outer support rods there are slidably mounted long prisms and on the inner support rods there are slidably mounted short prisms, the prismatic part of which is identical and where on the outside of both prisms there are slidably arranged carriers on the rods, on which front elastic stops are arranged, while the prisms and carriers are provided with the same vertical hole, the upper part of which is provided with a thread and the lower part forms a bearing surface for the clamping locking screw.

Description

260237

The present invention provides a versatile quick-release liner for precision positioning shafts in a pallet. At present, in particular for pallets fitted with shafts, shaped inserts serving a certain number of shaft types are used. A disadvantage of such shafts is their single use, which is not suitable for flexible automated manufacturing systems in terms of flexibility of the number of adjustments, different assortment, storage space and overall handling. Furthermore, at present, fixed rigidly mounted shafts are used in the pallet or fixed on the pallet, moreover in the range of diameters. In these systems, it is disadvantageous to override the delayed adjustment, the complexity of the alignment manipulations, and to require the shaft axis to be compensated for depending on the bearing diameters.

The above drawbacks are eliminated by the versatile quick-fit insert for accurately positioning the mounted shafts in the pallet, which consists in comprising four holders each of which is located in one corner of the pallet frame and is provided with two adjusting bolts, two supporting bars are mutually parallel to each other, and two prisms are slidably mounted on the two outer support rods, and short prisms are disposed on the inner support rods, the prismatic part of which is identical and when the outer sides of the two prisms are displaceable the carriers on which the front elastic stops are arranged, the prisms and carriers being provided with a straight vertical opening, the upper part of which is threaded and the lower part forming a bearing surface for the clamping locking screw.

The universal quick-set insertion accelerates the changeover to another type and number of shafts, while ensuring and rapid compensation of the axis change of the mounted shaft. An exemplary embodiment of a universal quick-change liner for accurately positioning mounted shafts in a pallet is shown schematically in FIG. 1. In FIG. 2, the fastening is clamped by a locking bolt.

A bracket 2 is fixed to the frame 1 of the pallet 11, at the same height from the base surface, in each corner. Two holes are provided in the bracket 2 so that threaded adjusting screws 3, which are screwed into the holes, can be adjusted to the free height. The supporting rods 4 are provided at their ends with a hole for attachment to the upper part of the adjusting screw 3. On the support rods 4 it is possible to move the long prisms 5 as well as the short springs 6 and the supports 7 with the front elastic supports 8. , their position being secured by the clamping screw 9.

The locking screw 9 is screwed into the through hole 10 provided with the upper part by the thread, the lower part serving the guides. The clamping screw 9 has a tapered shank which allows the prism to slide along the support rod 4. When screwed in, it rests against the conical surface of the support 4 and forms a clamping connection between the prism, 6 and the support rod 4. Long prism 5 and short prism 6 have the same prismatic part, they differ only in the length of their ends. Long Prism 5 is slipped onto the outer support 4, short Prism 6 on the inner.

Flapping of the mounted shaft

The shaft 12 is positioned on the universal quick-fit liner so that it is supported by a pair of prisms 5, 6, long, respectively, 5 and a short prism 6, at the same time curved by the front stops 8. The front stop 8 positions the slope, which allows i pres-not define the steer between the ends of the shafts12 in the row behind. Since both prisms 5,6 have an annular profile, when the set shaft 12 is placed in such a pair of its outside of the take-off plane in order to get it, it is necessary to adjust the support rods 4 by the adjusting screws 3, whereby the corresponding prism is lifted or starts at the desired height. This achieves that the shaft 12 can be supported in any location.

Since all of the associated prisms S, 6 are disposed on the support rod 4, the shafts 12 on the pallet 11 are disposed at the same time. The number of shafts 12 is prism 5, 6 determined by the maximum diameter of the shafts 12 depending on the size of the pallet 11 in the given direction. The storage diameter is theoretically selectable from 0 mm to the dimension given by the difference between the maximum diameter and the clearance required for the shafts. paddle. By adjusting the screws 3, it is possible to fine-tune the height of the pallet 11 from its base surface to correct the shaft axis 12.
