[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a novel fixture for precision parts machining, comprising a base 1 and a fixing groove 2. The fixing groove 2 is formed on the top inner wall of the base 1. A fixing plate 3 is fixedly connected to the left outer wall of the base 1. The base 1 serves as the basic support component of the fixture, providing a stable mounting plane for the entire fixture. The fixing groove 2 is used to limit and guide components such as the movable plate 71, ensuring their movement in a predetermined direction, thereby guaranteeing the stability of the fixture during operation. A servo motor 4 is fixedly connected to the left outer wall of the fixing plate 3. The servo motor 4 serves as a power source, providing stable and precise power output to drive the rotating column 5 to rotate, providing power support for the operation of the adjustment mechanism 6. The output end of the servo motor 4 is fixedly connected to the rotating column 5 via a coupling. An adjustment mechanism 6 is fixedly connected to the right end of the rotating column 5. An auxiliary mechanism 7 is provided on the base 1. The adjustment mechanism 6 includes a clamping plate frame 61, which is fixedly connected to the outer wall of the right end of the rotating column 5. The clamping plate frame 61 is a component that directly contacts and clamps the part. By connecting with the rotating column 5, it can be adjusted in position under the drive of the rotating column 5, thereby achieving precise clamping of the part. A T-slot 62 is provided on the top inner wall of the clamping plate frame 61. T-plates 63 are slidably connected to the inner walls of the left and right sides of the T-slot 62. An extension plate 64 is fixedly connected to the top outer wall of the T-plate 63. An adjustment plate 65 is slidably connected to the left inner wall of the T-plate 63. An insert plate 66 is fixedly connected to the left outer wall of the adjustment plate 65. A compression spring 67 is fixedly connected to the right outer wall of the adjustment plate 65.

[0019] Reference Figures 2-4 There are two T-slots 62, which are respectively formed on the top and bottom outer walls of the clamping plate frame 61. There are also two T-plates 63, which are slidably connected to the bottom inner walls of the two T-slots 62. The two T-plates 63 cooperate with the two T-slots 62 to support and adjust the extension plate 64 from both top and bottom directions, further enhancing the stability of the extension plate 64 during clamping and ensuring reliable clamping of parts. Frosted pads are fixedly connected to the left and right outer walls of the adjusting plate 65. The frosted pads increase the contact area between the operator and the adjusting plate 65. The friction between the plates facilitates the operation of the operator to pull and push the adjustment plate 65, improving the convenience and comfort of operation. The insertion plate 66 penetrates the left outer wall of the T-shaped plate 63. The end of the compression spring 67 away from the adjustment plate 65 is fixedly connected to the right inner wall of the T-shaped plate 63. A wear-resistant pad is fixedly connected to the side outer wall of the insertion plate 66. The wear-resistant pad can reduce the frictional wear between the insertion plate 66 and the inner wall of the clamping plate frame 61, extend the service life of the insertion plate 66 and the clamping plate frame 61, and at the same time ensure the smoothness of the insertion plate 66 during insertion and removal. The insertion plate 66 penetrates the left inner wall of the clamping plate frame 61.

[0020] Reference Figures 3-4The auxiliary mechanism 7 includes a movable plate 71, which is slidably connected to the top outer wall of the fixed groove 2. A sliding plate 72 is fixedly connected to the bottom outer wall of the movable plate 71. A threaded rod 73 is threadedly connected to the inner side wall of the sliding plate 72 via a threaded sleeve. The engagement of the threaded rod 73 and the threaded sleeve converts rotational motion into linear motion. By rotating the threaded rod 73, the movement distance of the sliding plate 72 and the movable plate 71 can be precisely controlled, thereby achieving precise adjustment of the clamping force on the parts. An adjusting plate 74 is fixed to the right end of the threaded rod 73. A pointing mark 75 is provided on the right outer wall of the adjusting plate 74. The pointing mark 75 can intuitively display the rotation angle and position of the adjusting plate 74, making it convenient for operators to accurately control the movement distance of the movable plate 71, ensuring consistent force and position when clamping parts each time, and improving the consistency and accuracy of processing. A insertion rod 76 passes through the right inner wall of the adjusting plate 74. A positioning hole 77 is provided on the right outer wall of the base 1. The sliding plate 72 is slidably connected to the left and right inner walls of the fixed groove 2. There are two rotating columns 5, which are rotatably connected to the left and right inner walls of the movable plate 71 and the fixed plate 3 respectively through bearings. A reflective sticker is fixedly connected to the right outer wall of the pointing mark 75. The reflective sticker can make the pointing mark 75 more conspicuous in low light conditions, so that the operator can clearly observe the position of the adjustment plate 74 in various working environments and ensure the accuracy of operation. The insertion rod 76 passes through the interior of the positioning hole 77. There are several positioning holes 77, which are arranged in a ring on the right outer wall of the base 1. The multiple ring-shaped positioning holes 77 can provide a variety of different positioning options to meet the clamping needs of parts of different sizes and shapes, so that the fixture can adapt to a wider range of parts processing scenarios and improve the practicality and flexibility of the fixture.

[0021] Working principle: Based on the size of the part to be clamped, the adjusting plate 65 is pulled in advance to move the insert plate 66. The insert plate 66 moves and separates from the inner wall of one side of the clamping plate frame 61. Then, the T-shaped plate 63 is pulled out from the T-slot 62. Then, the expansion plate 64 is separated from the clamping plate frame 61, so that the clamping surface is reduced, which is suitable for clamping smaller parts and reduces the impact of the clamping plate frame 61 on the normal operation of other equipment during clamping. At the same time, the adjusting plate 74 is rotated to rotate the threaded rod 73. The rotation of the threaded rod 73 drives the sliding plate 72 to move. The movement of the sliding plate 72 drives the movable plate 71 to move. The movement of the movable plate 71 causes the clamping plate frame 61 on the fixed plate 3 to move closer to each other, clamping and fixing the part. Then, the insert rod 76 is inserted into the corresponding positioning hole 77 to prevent the adjusting plate 74 from rotating on its own and affecting the clamping force between the movable plate 71 and the fixed plate 3.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
