Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to the improvement of a super-finishing planer for woodworking with replaceable blades. It has a field of application in which it simplifies the man-hours required to replace spare blades.

(Prior art) As mentioned in the previous section, a super-finishing plane machine that uses disposable blades has already been developed, but it requires man-hours to replace them, and they can only be replaced several times a day. , it is necessary to reduce the man-hours as much as possible to make replacement easy, but on the other hand, the cutting amount is 0.2~
The amount is as small as 0.5mm, and it must be matched to the material of the wood being cut, and the cutting precision must be maintained accurately until the next time the blade is replaced.
However, none of the conventional replaceable blade superfinishing planers for woodworking satisfies these mutually contradictory requirements.

(Problems to be solved by the invention) The problem of the invention is to solve the requirements stated in the previous section.

(Means for solving the problem) The present invention aims to solve the problem mentioned in the previous section. forming a supporting surface;
A cutter with a cutting edge that allows fine adjustment of elevation at one end of the cutting tool support, and a vertical slope set away in the material feeding direction from the tip facing the cutting edge, and with the upper surface as the material feeding surface. A replacement blade is installed on a slope so that it can be finely adjusted in the vertical direction by screwing it into the supporting surface through a fixing bolt whose head does not protrude from the top surface of the support plate so that it can be finely adjusted in the material feeding direction. A replaceable blade protruding from the material feeding surface is sandwiched and fixed between the holding plate and the blade support plate, a groove is formed in the blade support plate above the head of the fixing bolt, and the blade can be freely inserted into and removed from the groove and the blade can be fed. This invention relates to a super-finishing planer for woodworking with replaceable blades, which is characterized by a lid fitted with a lid having the same surface as the material surface.

The recessed hole of the present invention can be applied not only to the material feeding table but also to a knife stock, as shown in Utility Model Application Nos. 60-152777 to 152781, for example.

A preferred embodiment of the present invention will be described with reference to the accompanying drawings.

(Example) FIG. 1 shows an outline of a super-finishing planer 1, in which the material feeding surface of a material feeding table 3 that can be raised and lowered by a handle 2 is a blade support section 4, and a recessed hole 5 is formed in the support section 4. is recessed and a support surface 6 is formed at the bottom of the support surface 6.
The tip end in the material feeding direction is defined as the wood chips discharge port 7 of the material feeding table 3.

Reference numeral 8 denotes a cutting edge protruding from the shoulder of the end of the recessed sinkhole 5 in the material feeding direction and attached above the recessed sinkhole 5;
The lower surface corresponding to the upper support surface 9 is made into a slope 8a, a wedge piece 10 is interposed between the support surface 9 and the blade mouth 8, and the wedge piece is connected to the adjustment screw 11 on the lower side of the blade mouth 8,
The adjustment screw 11 is rotated to finely adjust the elevation of the blade tip 8. (FIG. 4) A cutter support plate 12 whose tip is opposed to the blade opening 8 is fitted into the recessed hole 5 and supported by the support surface 6, and the tip of the blade support plate 12 corresponding to the blade opening 8 and the support surface 6 are fitted. A vertical slope 13 is provided between them, and a replaceable blade holding plate 15 is attached to the slope 113 by bolts 14 passed through long holes 16 in the front and back direction and screwed to the slope 13. The spring 17 fitted on the slope 13 is pressed against the slope 13.

Numeral 18 is a fixing bolt whose head 19 has a length that does not protrude from the upper surface of the blade support plate 12, and is firmly screwed into the support surface 6 through an elongated hole 20 provided in the blade support plate 12 in the longitudinal direction. Reference numeral 21 denotes a dovetail groove provided in the blade support plate 12 so as to pass through the upper end of the elongated hole 20, and a lid 22 having a trapezoidal cross section is attached to this groove. Lid 2
2 is designed to be able to be pulled out laterally from the upper surface of the blade support plate 12, and is set at the same height as the upper surface of the support plate 12. Since the upper surface of the blade support plate 12 is aligned with the material feeding surface of the material feeding table 3, the upper surface of the lid 22 also constitutes a part of the material feeding surface.

A notch 23 into which a replaceable blade 24 is fitted is provided on the lower surface of the tip of the blade support plate 12, and the notch 23 and the replaceable blade holding plate 1 are provided.
A replacement blade 24 is sandwiched between the blades 5 and 5.

In this embodiment, the cutting thickness is adjusted using the adjusting screw 11 of the blade opening 8.
Determined by vertical movement. Further, the tip surface of the cutting edge presser plate 15 is finely adjusted in the vertical direction using the elongated hole 16 and the bolt 14. Furthermore, the distance between the replaceable blade 24 and the blade mouth 8 is slightly shifted to the front or rear side of the long hole 20 of the blade support plate 12 and the fixing bolt 18,
By adjusting these three points, necessary adjustments can be made to the replaceable blade type super finishing planer.

(Function of the invention) When replacing the replaceable blade 24, the invention removes it from the blade support plate 12 by sliding the cover 22,
8 from the long hole 20, lift the blade support plate 12 as shown in Figure 1, loosen the bolt 14 to widen the space between the notch 23 and the blade retainer plate 15, and remove the old replaceable blade 24 and the new replaceable blade 24. It can be easily applied without turning the blade support plate 12 upside down.

(Effect of the invention) The present invention has the above-described structure and operation, and the blade support plate 12 is inserted into the fixing bolt 1 from the recessed hole 5 provided in the blade support part 4 of the planer (or knife stock).
The spare blade 24 can be removed by loosening the bolt 14 on the slope 13 without having to turn it upside down or perform any other operations.
To provide a blade that can be quickly replaced and reused, and to significantly reduce the man-hours required for replacing blades, which are required to be replaced every two hours when the amount of cutting is large, and to improve operating efficiency. It does not require much re-adjustment to reset various parts of super-finish cutting by replacing spare blades, and it can handle all changes in cutting conditions.
This has the effect of providing a super-finishing planer for woodworking with replaceable blades that emphasizes work efficiency.
