The patent No. ZL95201498.X, the patent specification of the utility model with the date of authorization announcement on March 3, 1996 discloses a replaceable soft claw, which consists of a soft claw base. Composed of the soft claw head, the soft claw base has a convex key connected to the groove on the soft claw head, and the bolt passes through the soft claw base and the soft claw head to connect the soft claw base and the soft claw head together. To disassemble the fixed structure, it is necessary to slot and drill holes on the soft claw head. Due to the short life of the soft claw head and fast consumption, the complex processing of the soft claw increases a lot of workload, and the efficiency is low and the cost is high.

Contents of the invention

The purpose of the utility model is to provide soft claws for machining, which can reduce the processing and production procedures of the soft claw head while ensuring that super-long special-shaped parts can be clamped, so as to improve efficiency and reduce workload.

In order to solve the above-mentioned problems, the soft claw for machining of the utility model includes a plate-shaped soft claw base and a soft claw head, wherein one end of the soft claw base has an insertion groove for inserting with a chuck, defining the The direction in which the soft claw base is consistent with the axial direction of the adapter chuck is the up-down direction, the direction consistent with the radial direction of the adapter chuck is the left-right direction, and the end with the insertion groove is the left end. The soft claw base The thickness direction is the front-to-back direction, the lower end surface of the soft claw base is provided with an insertion slot for inserting the soft claw head, and the insertion groove extends to the right along the left and right direction, and the soft claw head is inserted into the In the insertion groove, at least two threaded holes connecting the inside and outside of the insertion groove are distributed along the left and right directions on the front side or the rear side of the soft claw base, and the threaded holes connecting the inside and outside of the insertion groove are arranged on the right end surface. holes, and in each of the threaded holes, anti-loosening screws are screwed to tighten the soft claw head. The head is clamped firmly.

An anti-loosening screw base for lengthening the threaded hole is provided on the front side or the rear side of the soft claw base.

The soft claw base is provided with a knurled surface which is convenient for turning the soft claw base.

The utility model is provided with an insertion groove on the soft claw base, which is used to insert the soft claw head of the super-long special-shaped part into it, and the soft claw head is pressed and fixed by the anti-loosening screw on the soft claw base. Therefore, the requirements for the connection and fixation of the soft claw head are reduced, and there is no need to slot or open holes on the soft claw head. While ensuring that super long special-shaped parts can be clamped, the processing and production procedures of the soft claw head are reduced, and the efficiency is improved and the work is reduced. volume and reduce costs.

Detailed ways

Below in conjunction with accompanying drawing, the utility model embodiment is described in detail:

The embodiment of soft claws for machining, as shown in Figures 1 to 4, includes a plate-shaped soft claw base 5 and a soft claw head 3, wherein one end of the soft claw base 5 has an insert for inserting with a chuck. Groove 6, and the end surface of the end is provided with a rectangular thread 7 for matching with the flat rectangular thread on the chuck. The thread fit can make the soft jaw base 5 move on the chuck along the radial direction of the chuck, defining The direction in which the soft jaw base 5 is consistent with the axial direction of the adapter chuck is the up-down direction, the direction in line with the radial direction of the adapter chuck is the left-right direction and the end with the insertion groove is the left end. The thickness direction of the base 5 is the front-to-back direction, and the lower end surface of the soft claw base 5 is provided with an insertion groove for inserting the soft claw head. The insertion groove extends to the right along the left and right direction, and the soft claw head is inserted Connected in the slot, on the front side of the soft claw base 5, there are two threaded holes connecting the inside and outside of the slot along the left and right direction, and two connecting holes distributed along the up and down direction are arranged on the right side end surface. The threaded holes inside and outside the socket are all screwed in each threaded hole to set the anti-loosening screw 1 of the top-tightening soft claw head 3, and the anti-loosening screw 1 and the nail head of the anti-loosening screw 1 facing the socket The groove wall cooperates to clamp and fix the soft claw head 3. In order to effectively screw the anti-loosening screw 1, an anti-loosening screw base 4 for lengthening the threaded hole can also be set on the front side of the soft claw base. The claw base 5 is provided with a knurled surface 8 which is convenient for turning the soft claw base 5 .

When the embodiment of the utility model is in use, insert the soft claw head used for clamping the super-long special-shaped parts into the insertion groove of the soft claw base, tighten the anti-loosening screw, and then install the soft claw base on the clip. The disc can be used, and the soft claw head can be trimmed according to the shape of the processed part.
