However, the traditional process soft jaws use welding methods to connect the soft jaw head part with the chuck jaws, and the chuck jaws With the loss of the use value of the soft claw head, it is scrapped. 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 a durable soft claw for machining, and reduce the installation requirements of the soft claw head under the premise of ensuring the durability of the soft claw head.

In order to solve the above-mentioned problems, a durable soft jaw for machining of the utility model includes a plate-shaped soft jaw base and a soft jaw head, wherein one end of the soft jaw base has an insertion hole for inserting with a chuck. groove, defining the direction that the soft claw base is consistent with the axial direction of the adapter chuck as the up-down direction, the direction that is 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, said The thickness direction of the soft claw base is the front-to-back direction, and the lower end surface of the soft claw base is provided with an insertion slot for inserting the soft claw head extending upwardly and downwardly, and the soft claw head is inserted into the socket. In the insertion slot, the upper end surface of the soft claw base is provided with a push screw that pushes the soft claw head to move downward, and a connecting plug is provided on the front side or rear side and the right end surface of the soft claw base. The threaded hole inside and outside the connecting groove, the anti-loosening screw that tightens the soft claw head is screwed in the threaded hole, and the anti-loosening screw and the wall of the insertion groove facing the nail head of the anti-loosening screw will The soft claw head is clamped and fixed.

A clamping piece is provided between the soft claw head and the advancing screw.

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.

In the utility model, an insertion slot for the insertion of the soft claw head is set on the soft claw base, and the soft claw head is pressed and fixed by the anti-loosening screw on the soft claw base, thus reducing the connection and fixing requirements for the soft claw head , there is no need to slot or open holes on the soft claw head, which reduces the workload of processing the soft claw head and improves production efficiency. Screw, when the soft claw head is worn out, screw the push screw to make the soft claw head move down, compensate for the worn part, and can continue to use. This soft claw reduces the installation requirements for the soft claw head on the premise of ensuring the durability of the soft claw head. .

Detailed ways

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

A durable soft jaw embodiment for machining, as shown in Figures 1 to 4, comprises a plate-shaped soft jaw base 5 and a soft jaw head 3, wherein one end of the soft jaw base 5 has a The insertion slot 6 for insertion, 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 on the chuck along the radial direction of the chuck. Direction movement, define the direction that the soft jaw base 5 is consistent with the axial direction of the adapter chuck as the up-down direction, the direction that is 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 thickness direction of the soft claw 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 extending upwards along the up and down direction, and the soft claw head 3 is inserted in the insertion groove, and the soft claw The upper end surface on the base 5 is provided with the push screw 9 that pushes the soft claw head 3 to move downward, and the front side or the rear side of the soft claw base 5 and the position corresponding to the said insertion groove on the right side end surface are provided with There is a threaded hole connecting the inside and outside of the socket, and the threaded hole is screwed with an anti-loosening screw 1 to tighten the soft claw head 3, and the anti-loosening screw 1 and the wall of the socket groove facing the nail head of the anti-loosening screw 1 The soft claw head 3 is clamped and fixed. In order to make the soft claw head 3 be evenly stressed and not be damaged by the push screw 9, a clamping piece 2 is provided between the soft claw head 3 and the push screw 9. In order to effectively rotate the fortification The loose screw 1 can also be provided with an anti-loosening screw base 4 for lengthening the threaded hole on the front side or the rear side of the soft claw base 5, and the soft claw base 5 is provided with a soft claw base 5 for easy dialing The knurled surface8.
