Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0025] In combination with the drawings, Figures 1-4 The present application provides a hard alloy compact processing clamping mechanism, which comprises a support base 1.

[0026] The support base 1 can be connected by bolts on the grinding machine for hard alloy compact processing.

[0027] In the embodiment, the clamping block one 2 is bolted with a clamping block one 2, and the top of the clamping block one 2 is movably provided with a clamping block two 3. The inner side of the clamping block one 2 is provided with a plurality of anti-skid teeth 4.

[0029] In the embodiment, the inner side of the clamping block two 3 is provided with a plurality of anti-skid teeth 4.

[0030] The clamping block two 3 can be used to increase the clamping height of the clamping block one 2. The clamping block two 3 with anti-skid teeth 4 has the same function and effect as the clamping block one 2 with anti-skid teeth 4.

[0031] In the embodiment, the clamping block one 2 and the clamping block two 3 are both provided with a V-shaped clamping groove, and the anti-skid teeth 4 are arranged in the V-shaped clamping groove.

[0032] The opening size of the V-shaped clamping groove gradually increases, which can meet the needs of hard alloy compacts of various diameters. The anti-skid teeth 4 can be arranged along the V-shaped path of the V-shaped clamping groove. The hard alloy compact can be more stable through the contact between the anti-skid teeth 4 and the outer surface of the hard alloy compact.

[0033] In the embodiment, one side of the anti-skid tooth 4 is fixedly connected with a socket 41, and a plug groove for inserting the socket 41 is formed in the inner wall of the V-shaped clamping groove.

[0034] The socket 41 can be arranged in a cross-shaped structure. It can be inserted downward at the top of the clamping block one 2 or the clamping block two 3, so that the anti-skid tooth 4 is arranged in the V-shaped clamping groove to provide support for the clamping of the hard alloy compact. Since each anti-skid tooth 4 is provided with a socket 41, the anti-skid tooth 4 can be easily replaced when it is damaged due to wear.

Since the clamping block two 3 is arranged in the positioning groove one 9, another clamping block two 3 can be used to increase the clamping height when the clamping height needs to be increased subsequently. The positioning column one 8 on the clamping block two 3 and the positioning groove one 9 on the lower clamping block two 3 are inserted and matched to realize the stacking of the clamping height.

[0040] Since the sliding seat 52 can move linearly, the clamping plate one 6 can move to a position facing the clamping block one 2, the hard alloy compact is placed on the support base 1 and located between the clamping block one 2 and the clamping plate one 6, the pair of anti-skid columns 11 arranged on the clamping plate one 6 is used to increase the clamping points of the hard alloy compact, the anti-skid columns 11 and the anti-skid teeth 4 can jointly act on the outer surface of the hard alloy compact, the stable clamping effect is met, the subsequent hard alloy compact is stably clamped and fixed by the grinding machine, and since the clamping block one 2 is provided with the V-shaped clamping groove, the machining requirement can be met when clamping hard alloy compacts with different diameters, and the machining steps are reduced.

[0041] In the embodiment, the clamping plate two 7 is movably arranged on the top of the clamping plate one 6, and the pair of anti-skid columns 11 is fixedly connected to one side of the clamping plate two 7.
