Detailed Description

Preferred embodiments of the present application are described in detail below with reference to examples. However, it should be understood by those skilled in the art that these exemplary embodiments are not meant to limit the present application in any way. Furthermore, the features in the embodiments of the present application may be combined with each other without conflict. In different figures, identical components are denoted by identical reference numerals and other components are omitted for the sake of brevity, but this does not indicate that other components may not be included. It should be understood that the dimensions, proportions and numbers of elements in the drawings are not intended to limit the present application.

At present, a cutting pick is kept in a horizontal state by frequently adopting a double-tip clamping mode in the process of processing a chip discharge groove on the peripheral surface of the cutting pick, however, the cutting pick is easy to damage the end surface of the cutting pick by the clamping mode, and the cutting pick is easy to rotate.

In view of this, the inventor designs a clamp for wear-resisting pick processing, can protect the pick terminal surface not impaired, and reduce the pick and take place the probability of rotating.

Example 1

In this embodiment, the jig 1 includes:

a base 10;

the sleeve 20, the sleeve 20 is horizontally arranged through the base 10;

the screw 30 is screwed in the sleeve 20;

wherein, the terminal surface rigid coupling of screw rod 30 has globular clamping part 40, and clamping part 40 has magnetism, and clamping part 40 magnetism is inhaled in the reserve groove of pick 2 terminal surface with ground adaptation.

In this embodiment, utilize anchor clamps 1 to press from both sides fastening timing to pick 2, first two screws 30 of rotating are to keeping suitable interval, then arrange pick 2 in between two clamping parts 40, rotate two screws 30 once more and make clamping part 40 magnetism inhale the preformed groove in the pick terminal surface, then rotate pick 2, in order to drive two screws 30 and remove in opposite directions, thereby utilize two clamping parts 40 to press from both sides the pick tightly fixedly, the spherical contact can avoid causing the damage to pick 2 terminal surfaces, magnetism is inhaled fixed connection and can be reduced pick 2 and take place pivoted probability.

In the present embodiment, the base 10 is configured into a U shape as a whole, two side plates 11 of the base 10 are vertically arranged with a bottom plate thereof, the two side plates 11 are vertically arranged, and the sleeve 20 is vertically inserted through the side plates 11 and fixedly connected with the side plates 11, for example, the sleeve 20 and the base 10 are an integral structure.

One sleeve 20 is arranged on each side plate 11, the two sleeves 20 on the two side plates 11 are symmetrically arranged, the screw rods 30 penetrate through the inner parts of the sleeves 20 and are in threaded connection with the sleeves 20, the two screw rods 30 are provided with threads with opposite rotation directions, and the two screw rods 30 are coaxially arranged.

In the present embodiment, the clamping portion 40 is configured as a solid sphere, the clamping portion 40 has magnetism, for example, the clamping portion 40 is a magnet, the clamping portion 40 is fixed to the inner end of the threaded rod 30, the axis of the threaded rod 30 passes through the sphere center of the clamping portion 40, and the two clamping portions 40 are located on the same horizontal plane.

In this embodiment, spherical preformed grooves are formed on two end faces of the cutting pick 2, the preformed grooves are matched with the shape of the clamping portion 40, and the clamping portion 40 is fixedly connected with the preformed grooves in a magnetic adsorption manner after moving into the preformed grooves.

It should be understood that, after the corresponding magnetic adsorption of reserve groove on two clamping parts 40 and the pick 2 is connected, the magnetic adsorption between clamping part 40 and the reserve groove is as an organic whole with two screws 30 with pick 2 connection, when pick 2 rotates, can drive two screws 30 in step and rotate, because two screws 30 have the opposite screw thread of direction of turning, so, when rotating pick 2, can make two screws 30 make the phase shift, improved the clamp force of two screws 30 to pick 2, can reduce pick 2 and take place pivoted probability.

Although embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application, and that changes, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present application.
