[0027] like Figures 1 to 4 As shown, the grinding fixture of the utility model includes: a base 1, and a plurality of clamping structures 2 are evenly arranged on the bottom surface of the base 1 with its central axis as the center; wherein the clamping structure 2 at least includes a bearing rod 21 arranged on the bottom surface of the base 1, a clamping claw 23 rotatably installed on the bottom end of the bearing rod 21 through an elastic member 22, and a limiting rod 24 arranged on the bearing rod 21 on the side away from the central axis of the base 1; wherein, under the action of the elastic member 22, the clamping claw 23 is always biased toward the side away from the central axis of the base 1, and rests on the limiting rod 24 to be in a static position.

[0028] See also Figure 1 , Figure 2 The clamping structures 2 have four and are evenly arranged on the bottom surface of the base 1 with the central axis of the base 1 as the center; in other possible implementations, the clamping structures 2 can also be two, three, five, six, etc., without specific limitation.

[0029] See also Figure 1 , Figure 2 In the initial state, under the action of the elastic member 22, the bottom end of the clamping jaw 23 is deflected toward the side away from the central axis of the base 1. At the same time, due to the extension of the limiting rod 24, the surface of the clamping jaw 23 on the side away from the central axis of the base 1 abuts against the bottom end of the limiting rod 24, so that the clamping jaw 23 is inclined and is in an open state.

[0030] Before polishing the product, first place the product to be polished directly in the space formed by the four clamping jaws 23, or fix the product on the carrier and place the carrier in the space formed by the four clamping jaws 23, then control the limit rod 24 to move downward so that the bottom end of the limit rod 24 presses downward against the clamping jaws 23, so that the bottom end of the clamping jaws 23 moves toward the central axis of the base 1 to clamp the product or the carrier; the present application uses the limit rod 24 to directly control the clamping jaws 23 to perform clamping operations, which effectively reduces the complexity of the polishing fixture structure. At the same time, it can more conveniently fix more types of products, has the characteristics of simple structure and convenient operation, and is practical.

[0031] In one or more embodiments, the clamping structure 2 further includes a first driving device 25 for controlling the limit rod 24 to move along the length direction of the bearing rod 21. Figure 2 The first driving device 25 can be a driving cylinder, which can improve the automation degree of the grinding fixture by controlling the limiting rod 24 to move vertically along the length direction of the bearing rod 21 through the driving cylinder.

[0032] In one or more embodiments, the elastic member 22 is a coil spring having an inner end and an outer end, wherein the inner end is mounted on the bearing rod 21 and the outer end is disposed on the clamping jaw 23. In other possible embodiments, the elastic member 22 may also be a hook spring, wherein one end of the hook spring is hooked on the bearing rod 21 and the other end is hooked on the clamping jaw 23, and it is sufficient that the bottom end of the clamping jaw 23 always has a tendency to move away from the central axis of the base 1.

[0033] In one or more embodiments, the clamping structure 2 is configured to be movable in a direction perpendicular to the central axis of the base 1. Through this arrangement, the clamping mechanism can clamp products of different sizes, thereby increasing the scope of application of the present application.

[0034] In one or more embodiments, a through slide groove 3 is formed on the base 1, and the bearing rod 21 is slidably installed in the slide groove 3. Figure 1 The bearing rod 21 can slide in the slide groove 3, that is, the bearing rod 21 moves in a direction perpendicular to the central axis of the base 1. There are four slide grooves 3, and each slide groove 3 corresponds to a set of clamping mechanisms.

[0035] In the first embodiment in which the bearing rod 21 moves along the slide groove 3 , a fixing portion 211 is formed at the top of the bearing rod 21 . The fixing portion 211 extends out of the top surface of the base 1 , and the fixing portion 211 is fixed to the base 1 by bolts.

[0036] See also Figure 1 The top surface of the base 1 and the fixing portion 211 are both formed with corresponding multiple screw holes, so that the bearing rod 21 can be fixed to the base 1 by bolts, thereby ensuring the stability of the clamping jaws 23 in clamping the product.

[0037] In the second embodiment in which the bearing rod 21 moves along the slide groove 3 , a second driving device is disposed on the base 1 , and the second driving device is used to drive the bearing rod 21 to move along the slide groove 3 .

[0038] The accompanying drawings do not show the connection relationship between the second driving device and the supporting rod 21; the second driving device can be a driving cylinder, and the driving shaft end of the second driving device is connected to the supporting rod 21. A plurality of second driving devices are used to synchronously control the supporting rod 21 to approach or move away from the central axis of the base 1, so as to adjust the distance between each clamping jaw 23 and enable the clamping jaws 23 to clamp products of different sizes.

[0039] In the third embodiment in which the supporting rod 21 moves along the slide groove 3, a servo motor 41 is arranged on the top surface of the base 1, a turntable 42 is installed on the rotating shaft end of the servo motor 41, a connecting rod 43 is rotatably installed on the bottom surface of the turntable 42, and the other end of the connecting rod 43 is rotatably installed on the supporting rod 21; the number of the connecting rods 43 corresponds one-to-one to the number of the supporting rods 21.

[0040] See also Figure 1 , Figure 4 When it is necessary to control the bearing rod 21 to slide in the slide groove 3, the rotating shaft end of the servo motor 41 is controlled to rotate clockwise or counterclockwise so that the turntable 42 drives the connecting rod 43 to rotate, so that the connecting rod 43 is expanded or contracted, and the movement of the bearing rod 21 in the slide groove 3 can be realized. The operation is convenient, the structure is simple, and the movement consistency of the bearing rod 21 is high.

[0041] In one or more embodiments, the clamping jaws 23 are detachably mounted on the bottom end of the bearing rod 21. Through this arrangement, the clamping jaws 23 can be replaced in time to meet the clamping of different types of products and facilitate grinding.

[0042] In one or more embodiments, the angle at which the clamping jaw 23 can rotate relative to the load-bearing rod 21 is 0-90°. The first driving device 25 controls the limit rod 24 to be fully extended, the clamping jaw 23 and the load-bearing rod 21 are in a colinear relationship, and the clamping jaw 23 and the load-bearing rod 21 are in a parallel relationship. The first driving device 25 controls the limit rod 24 to retract, and under the action of the elastic member 22, the clamping jaw 23 is perpendicular to the load-bearing rod 21, and the rotation angle of the clamping jaw 23 is 90°. By controlling the clamping jaw 23 to rotate at a large angle, the clamping force of the clamping jaw 23 can be controlled, which is suitable for clamping products of different hardness.

[0043] In addition, the utility model also provides a grinding device, which has the grinding fixture in any of the above embodiments.
