The machine table 1, the grinding mechanism 2, and the support plate 3 together form a surface grinder, which is prior art and can be realized by those skilled in the art. Since it is prior art, it will not be described in detail in this case. A positioning component is arranged on the lower surface of the support plate 3. The positioning component can drive the clamping components on both sides to open or close synchronously, facilitating the simultaneous fixation of the left and right sides of the workpiece, reducing the time spent on clamping, and improving the efficiency. The positioning component includes a guide plate 43. The support plate 3 is elastically connected to a connecting block 45 through a compression spring 47.

The upper surface of the slider 46 is provided with a clamping component. The clamping component is convenient for clamping and fixing workpieces of different shapes and has strong applicability. The slider 46 penetrates and is slidably connected to the upper surface of the support plate 3. The positioning component further includes a motor 41, which is prior art and can be realized by those skilled in the art. Since it is prior art, it will not be described in detail in this case. The output shaft of the motor 41 is fixedly connected to a threaded rod 42. Starting the motor 41 can drive the threaded rod 42 to rotate. A T-shaped groove 401 is opened on the rear surface of the guide plate 43. A T-shaped block 44 is slidably connected to the inner wall of the T-shaped groove 401. The T-shaped block 44, the connecting block 45, the slider 46, the compression spring 47, and the clamping component are provided in two groups and are symmetrically distributed about the center line of the support plate 3.
[0033] Refer to Figure 1 , Figure 2 , Figure 4 , the clamping component includes a clamping plate 51. A round block 54 is elastically connected to the inner wall of the clamping plate 51 through a connecting spring 53. A fixing rod 52 is fixedly connected to the left surface of the round block 54. The fixing rod 52, the connecting spring 53, and the round block 54 are provided in multiple groups and are distributed in an array on the left surface of the clamping plate 51. The left surface of the fixing rod 52 is set as an arc surface.
[0034] Refer to Figures 1-3, the guide plate 43 is slidably connected to the lower surface of the support plate 3 and slides in the front-rear direction. The right end of the rear surface of the guide plate 43 is provided with an inclined surface, and the left end of the rear surface of the guide plate 43 is provided with an inclined surface. The T-shaped groove 401 is opened on the inclined surface of the guide plate 43. The connecting block 45 is slidably connected to the lower surface of the support plate 3. One end of the compression spring 47 is fixedly connected to the right surface of the connecting block 45, and the other end of the compression spring 47 is fixedly connected to the inner wall on the right side of the support plate 3. When the connecting block 45 moves to the right, it will squeeze the compression spring 47 to generate a reaction force. The front surface of the connecting block 45 is provided with an inclined surface, and the T-shaped block 44 is located on the inclined surface of the connecting block 45. The inclined surface of the connecting block 45 is in contact with the inclined surface of the guide plate 43. The motor 41 is arranged on the front surface of the machine table 1, the threaded rod 42 passes through and is rotatably connected to the front surface of the machine table 1, and the threaded rod 42 passes through and is threadedly connected to the front surface of the guide plate 43. When the threaded rod 42 rotates, it can drive the guide plate 43 to move in the front-rear direction. The rear surface of the T-shaped block 44 is fixedly connected to the front surface of the connecting block 45, and the T-shaped block 44 and the connecting block 45 will move synchronously.
[0035] Refer to Figure 1 , Figure 2 , Figure 4 , the lower surface of the clamping plate 51 is fixedly connected to the upper surface of the slider 46. The fixing rod 52 passes through and is slidably connected to the left surface of the clamping plate 51. One end of the connecting spring 53 is fixedly connected to the left surface of the round block 54, and the other end of the connecting spring 53 is fixedly connected to the inner wall on the left side of the clamping plate 51. When the round block 54 moves to the right, it will stretch the connecting spring 53 to generate a reaction force.
[0036] Working principle: When the device is in use, first place the workpiece to be polished flat on the support plate 3, and then start the motor 41 to drive the threaded rod 42 to rotate. The rotating threaded rod 42 will drive the guide plate 43 to move forward. The forward-moving guide plate 43 will release the extrusion on the connecting block 45. The reaction force of the compression spring 47 will push the connecting block 45 to move towards the middle of the support plate 3. And the forward-moving guide plate 43 will drive the T-shaped groove 401 to move forward. The forward-moving T-shaped groove 401 will squeeze the T-shaped block 44. Under the influence of the reaction force of the compression spring 47 and the squeezing force of the T-shaped groove 401 on the T-shaped block 44, the connecting block 45 and the slider 46 will move towards the middle of the support plate 3.
[0037] The moving slider 46 will drive the clamping assembly to move synchronously. During the movement, the fixed rod 52 will contact the surface of the workpiece. At this time, the clamping plates 51 on both sides will continue to move towards the middle of the support plate 3. The fixed rod 52 that first contacts the workpiece will be squeezed, and then drive the circular block 54 connected to it to move and stretch the connecting spring 53 to generate a reaction force. The remaining fixed rods 52 will gradually insert into the gap of the workpiece to increase the contact points with the workpiece. When the workpiece is clamped, the motor 41 device will be turned off and remain stable, and then the grinding mechanism 2 will be started to grind the surface of the workpiece.
[0038] After grinding and leveling, turn off the grinding mechanism 2 and start the motor 41 to drive the threaded rod 42 to rotate in the reverse direction. The reverse-rotating threaded rod 42 will drive the guide plate 43 to move backward. The backward-moving guide plate 43 will squeeze the inclined surface of the connecting block 45, and the moving guide plate 43 will drive the T-shaped groove 401 to move and squeeze the T-shaped block 44. Under the influence of the guide plate 43 squeezing the connecting block 45 and the T-shaped groove 401 squeezing the T-shaped block 44, the connecting block 45, the slider 46 and the clamping assembly will separate, the clamping assembly will release the clamping of the workpiece, and the fixed rod 52 and the circular block 54 will return to their original positions under the influence of the reaction force of the connecting spring 53. The moving connecting block 45 will squeeze the compression spring 47 to generate a reaction force. After the clamping of the workpiece is released, the workpiece is removed.
[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
