The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0024] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate and simplify the description of the utility model and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the utility model. Furthermore, the terms "first," "second," and "third," etc., are used solely for distinction and description and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0026] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] See also Figure 1-4 , The utility model provides an embodiment of a mechanical auxiliary fixture for a polishing machine, comprising a mounting plate 5, a transmission mechanism 8 and a fixing mechanism 9. The upper surface of the mounting plate 5 is symmetrically provided with mounting grooves 7, and a mounting block 6 is movably provided inside the mounting groove 7. A fixing mechanism 9 is provided at the bottom of the mounting block 6. The fixing mechanism 9 includes a hexagonal screw head 907, and the sides of the two hexagonal screw heads 907 close to each other are fixedly connected to a transmission rod 908, and the sides of the two transmission rods 908 close to each other are fixedly connected to a threaded rod 902, and the outer wall of the threaded rod 902 is threadedly connected to a threaded block 904, and the lower end surface of the threaded block 904 is movably provided with a cross bar 903, and the top of the threaded block 904 is fixedly connected to a movable block 901, and the two movable blocks 901 are each provided with a fixing hole 905 on the side away from each other. A fixing rod 906 is movably provided inside the fixing hole 905, and the fixing rod 906 is fixedly connected to the movable block 901, and the top of the mounting block 6 is fixedly connected to the support plate 2;

[0028] Specifically, such as Figure 1 、 Figure 2 and Figure 4As shown, when in use, when the clamp needs to be installed, the mounting block 6 at the bottom of the support plate 2 is inserted into the mounting groove 7, and then the hexagonal screw head 907 is rotated by a tool. The rotation of the hexagonal screw head 907 drives the threaded rod 902 to rotate through the transmission rod 908, and the rotation of the threaded rod 902 drives the threaded block 904 to move. The movement of the threaded block 904 drives the movable block 901 to move, and the movement of the movable block 901 drives the fixing rod 906 to move toward the fixing hole 905 until the fixing rod 906 is inserted into the fixing hole 905, thereby completing the fixation of the mounting block 6 and then completing the installation of the clamp. Similarly, it can be achieved that the clamp is easy to disassemble. By facilitating the disassembly and assembly of the clamp, it is convenient to better meet the usage requirements of different scenarios, thereby improving the practicality of the clamp.

[0029] Both sides of the top of the support plate 2 are fixedly connected to the fixed plate 1, and a transmission mechanism 8 is set inside the fixed plate 1. The transmission mechanism 8 includes a rotating plate 801, and the rotating plate 801 is rotatably set at the rear end of one of the fixed plates 1. The front end of the rotating plate 801 is fixedly connected to a rotating rod 802, and one end of the rotating rod 802 extends to the interior of the fixed plate 1. One end of the rotating rod 802 is fixedly connected to a bidirectional screw 805. The outer wall of the bidirectional screw 805 is threadedly connected to a moving block 804. The surface of the moving block 804 is movably provided with a limit rod 803. The moving block 80 4 is fixedly connected to the right side of the first transmission block 806, and the first transmission block 806 is fixedly connected to the outer wall close to the transmission plate 3. The right side of the first transmission block 806 is located inside the other fixed plate 1 and a sliding rod 808 is provided. The outer wall of the sliding rod 808 is slidably sleeved with a sliding sleeve 807. The left side of the sliding sleeve 807 is fixedly connected to the second transmission block 809, and the second transmission block 809 is fixedly connected to the outer wall close to the transmission plate 3. A transmission plate 3 is movably provided between the two fixed plates 1, and the ends of the two transmission plates 3 close to each other are fixedly connected to a clamping block 4.

[0030] Specifically, such as Figure 1 、 Figure 2 and Figure 3As shown, when in use, when it is necessary to clamp the sample, the sample is placed between the two fixed plates 1, and then the rotating plate 801 is rotated. The rotating plate 801 rotates to drive the rotating rod 802 to rotate, and the rotating rod 802 rotates to drive the bidirectional screw 805 to rotate. The bidirectional screw 805 rotates to drive the two moving blocks 804 to move in a direction close to each other. The two moving blocks 804 move and drive the two first transmission blocks 806 to move. The two first transmission blocks 806 move through the mutual cooperation of the sliding sleeve 807, the sliding rod 808 and the second transmission block 809, driving the two transmission plates 3 to move in a direction close to each other, and the two transmission plates 3 move and drive the two clamping blocks 4 to move in a direction close to each other until they contact the two ends of the sample and effectively clamp and fix it. The operation is simple and the fixing effect is good, which can improve the polishing efficiency of the polishing machine and solves the problem of clamping the sample by the mutual cooperation of the fastening bolts and the fastening nuts. Although the operation is simple, the fixation of each sample requires frequent disassembly and assembly of the fastening bolts and the fastening nuts, which is more troublesome and will reduce the polishing efficiency of the polishing machine.

[0031] Working principle: In this application, when the sample needs to be clamped, the sample is placed between the two fixed plates 1, and then the rotating plate 801 is rotated. The rotation of the rotating plate 801 drives the rotating rod 802 to rotate, and the rotation of the rotating rod 802 drives the bidirectional screw 805 to rotate. The rotation of the bidirectional screw 805 drives the two moving blocks 804 to move in the direction of approaching each other. The movement of the two moving blocks 804 drives the two first transmission blocks 806 to move. The movement of the two first transmission blocks 806 drives the two transmission plates 3 to move in the direction of approaching each other through the cooperation of the sliding sleeve 807, the sliding rod 808 and the second transmission block 809. The movement of the two transmission plates 3 drives the two clamping blocks 4 to move in the direction of approaching each other until they contact the two ends of the sample and are effectively clamped and fixed. It is simple to operate and has a good fixing effect. To improve the polishing efficiency of the polishing machine, secondly, when the fixture needs to be installed, insert the mounting block 6 at the bottom of the support plate 2 into the mounting groove 7, and then use the tool to rotate the hexagonal screw head 907. The rotation of the hexagonal screw head 907 drives the threaded rod 902 to rotate through the transmission rod 908. The rotation of the threaded rod 902 drives the threaded block 904 to move. The movement of the threaded block 904 drives the movable block 901 to move. The movement of the movable block 901 drives the fixing rod 906 to move toward the fixing hole 905 until the fixing rod 906 is inserted into the fixing hole 905, thereby completing the fixation of the mounting block 6 and then completing the installation of the fixture. Similarly, it can be achieved that the fixture is easy to disassemble. By facilitating the disassembly and assembly of the fixture, it is easy to better meet the usage requirements of different scenarios, thereby improving the practicality of the fixture.
