It can be understood that the above-mentioned solution can be used in the scenario of diamond grinding block processing.
[0020] In this embodiment, the connecting plate 102 is fixedly mounted on the base plate 101, the outer clamping assembly is mounted on the connecting plate 102, and the inner clamping assembly is mounted on the connecting plate 102. This ensures that the grinding block 119 is evenly stressed, reduces errors during machining, and reduces the defective rate of the grinding block 119. The connecting plate 102 is mounted on the base plate 101 by welding, and supports the outer clamping assembly; the outer clamping assembly provides clamping force on the outer side of the grinding block 119.
[0021] In which, the connecting plate 102 has a fixing groove 107, the fixing cylinder 103 is fixedly installed in the fixing groove 107, the number of the support blocks 104 is two, the two support blocks 104 are respectively installed on the fixing cylinder 103, the support blocks 104 are slidingly connected to the fixing cylinder 103, each of the support blocks 104 is installed with the abutment block 105, the abutment block 105 is fixedly connected to the support block 104, the bearing 106 is fixedly installed in the fixing cylinder 103, the movable member is installed on the bearing 106, and the sliding member is installed on the fixing cylinder 103. The connecting plate 102 is provided with the fixing groove 107, which accommodates the fixed cylinder 103 and the grinding block 119; the fixed cylinder 103 supports the support block 104, the bearing 106, the movable member and the sliding member; the two support blocks 104 are respectively located on the left and right sides of the fixed cylinder 103, and the support blocks 104 support the abutment blocks 105, which slide on the fixed cylinder 103 to move the abutment blocks 105; the abutment blocks 105 abut against the inner side of the grinding block 119 to provide a clamping force on the inner side of the grinding block 119; the bearing 106 is located on the inner wall of the fixed cylinder 103, and the bearing 106 supports the movable member ; The moving member controls the movement of the support block 104; the sliding member provides elastic force to the support block 104; the grinding block 119 is placed in the fixed groove 107 through the fixed cylinder 103, and the support block 104 is pushed outward by the moving member, so that the abutment block 105 moves outward and abuts against the inner side of the grinding block 119, and the abutment block 105 is always abutted against the inner side of the grinding block 119, providing an inner clamping force to the grinding block 119, and then providing a clamping force to the outer side of the grinding block 119 through the outer clamping assembly, so that the grinding block 119 is evenly stressed, and it is less likely to have errors during the processing, thereby reducing the defective rate of the grinding block 119 processing.
[0022] Secondly, the screw rod 108 is mounted on the bearing 106, the threaded block 109 is mounted on the screw rod 108, the threaded block 109 is threadedly connected to the screw rod 108, the nut 110 is mounted on the screw rod 108, the nut 110 is threadedly connected to the screw rod 108, and the pushing block 111 is fixedly mounted on the threaded block 109. The screw rod 108 rotates on the bearing 106, and the screw rod 108 supports the threaded block 109, so that the threaded block 109 moves vertically up and down on the screw rod 108; the threaded block 109 supports the pushing block 111, and the rotation of the screw 108 converts the rotary motion into linear motion, so that the threaded block 109 drives the pushing block 111 to move up and down; the nut 110 fixes the screw 108 on the fixed cylinder 103, so that the screw 108 is not easily rotated by force; the pushing block 111 is sleeved and mounted on the threaded block 111 by welding. 09, the pushing block 111 pushes the supporting block 104, so that the supporting block 104 moves horizontally on the fixed cylinder 103; the grinding block 119 is placed in the fixed groove 107 through the fixed cylinder 103, and the screw 108 is rotated to make the screw 108 rotate on the bearing 106, so that the threaded block 109 drives the pushing block 111 to move downward, so that the pushing block 111 contacts the two supporting blocks 104, and pushes the supporting block 104 to move outward, so that the abutting block 105 abuts against the inner side of the grinding block 119.
[0023] Again, the fixed cylinder 103 has a placement groove 114 , and the number of the placement grooves 114 is two. The connecting spring 112 is installed in each placement groove 114 , and the slider 113 is installed on each connecting spring 112 . The slider 113 is fixedly connected to the support block 104 .

When the pushing block 111 is always in contact with the support block 104, the connecting spring 112 is in a stretched state. When the screw 108 rotates, the threaded block 109 drives the pushing block 111 to move upward, so that the pushing block 111 does not abut against the support block 104, the slider 113 is compressed by the connecting spring 112, driving the support block 104 to move inward, so that the abutting block 105 does not abut against the inner side of the grinding block 119.
[0024] Next, the clamping block 115 is mounted on the connecting plate 102 via the pushing member, and the gasket 116 is fixedly mounted on the clamping block 115. There are four clamping blocks 115, which provide an outer clamping force for the grinding block 119. The gasket 116 is welded to the clamping block 115, increasing friction and ensuring a tight fit between the clamping block 115 and the outer side of the grinding block 119. The pushing member pushes the clamping block 115 to move.
[0025] Then, one end of the screw rod 117 is mounted on the clamping block 115, and the other end of the screw rod 117 is mounted on the connecting plate 102. The knob 118 is fixedly mounted on the screw rod 117. The screw rod 117 is threaded and rotated on the connecting plate 102. At the same time, the screw rod 117 is limited and rotated on the clamping block 115. The rotation of the screw rod 117 converts the rotary motion into linear motion, pushing the clamping block 115 to move horizontally. The knob 118 facilitates the rotation of the screw rod 117.
[0026] When using the grinding block concentric fixture for a diamond press of this embodiment, the grinding block 119 is placed in the fixing groove 107 through the fixing cylinder 103, and the screw 108 is rotated to rotate the screw 108 in the bearing 106, so that the threaded block 109 drives the pushing block 111 to move downward, so that the pushing block 111 contacts the two supporting blocks 104, and the supporting blocks 104 are pushed outward to move the abutment block 105 outward to abut against the inner side of the grinding block 119, and then the nut 110 is used to rotate on the screw 108 until it contacts the fixing block 104. The cylinder 103 is abutted, and the screw 108 is fixed on the fixed cylinder 103, so that the abutting block 105 is always abutted against the inner side of the grinding block 119, providing an inner clamping force to the grinding block 119, and then the knob 118 is rotated to rotate the screw 117 on the connecting plate 102, pushing the clamping block 115 and the gasket 116 to move, so that the gasket 116 is abutted against the outer side of the grinding block 119, providing an outer clamping force to the grinding block 119, so that the grinding block 119 is evenly stressed, and it is less likely to have errors during the processing, thereby reducing the defective rate of the grinding block 119 processing.
