Description
Technical Field
[0001] The utility model relates to the field of processing devices, in particular to a fixture. Background Art
[0002] In the process of machining, fixtures are used to ensure the precise positioning and stable clamping of workpieces on machining equipment (such as machine tools). This can guarantee the accuracy and consistency of machining operations (such as milling, drilling, cutting, etc.). On the assembly production line, fixtures are used to correctly position and fix multiple components together for subsequent welding, bolting, or bonding operations. Fixtures can ensure the accurate alignment of components, improving the assembly efficiency and quality. Fixtures play an important role in the process of product quality inspection and measurement. They can help place the workpiece to be measured stably on the measuring equipment, ensuring the accuracy and repeatability of the measurement results.
[0003] The positioning devices of fixtures are used to ensure the precise positioning of workpieces in the fixture. These devices can be positioning pins, positioning blocks, V-grooves, etc., which cooperate with the positioning holes or protrusions on the workpiece to ensure that the workpiece is placed in the correct position. The mechanical clamping devices apply pressure by rotating the handle or adjusting the nut, while the hydraulic or pneumatic clamping devices achieve clamping through the pressure system. The adjustment device allows the operator to adjust the size or angle of the fixture according to the specific size or shape of the workpiece.
[0004] Traditional fixtures are usually designed for specific types or sizes of workpieces, such as regular-shaped metal plates, pipes, or parts. The design of these fixtures is usually based on standard sizes and shapes. Therefore, when facing workpieces with complex shapes or irregular sizes, their clamping effects may be limited. Traditional fixtures may not provide enough contact surfaces or stable clamping forces, which may cause the workpiece to move or shift during the machining process, resulting in inaccurate positioning or unstable clamping, thereby affecting the accuracy of machining or assembly. Summary of the Utility Model
[0005] In order to make up for the above deficiencies, the utility model provides a fixture, aiming to improve the problem that traditional fixtures cannot adapt to workpieces with different shapes or irregular sizes, resulting in inaccurate positioning or unstable clamping.
[0006] To achieve the above object, the utility model adopts the following technical solutions: A tooling fixture, comprising a workbench, a fixed plate is fixedly connected to the top of the workbench, a first push rod is fixedly connected inside the fixed plate, a slider is fixedly connected to the output end of the first push rod, a chute is opened inside the fixed plate, the side wall of the slider is slidably connected inside the chute, a support block is fixedly connected to the top of the slider, a plurality of rollers are rotatably connected to the inner wall of the support block, symmetrically arranged support plates are fixedly connected to the top of the fixed plate, and rollers are rotatably connected to both the support plates and the support block. A fixing component is arranged on the top of the workbench, and the fixing component is used to fix the base on the top of the workbench.
[0007] Further, the fixing component includes a base, and the base is fixedly connected to the top of the base.
[0008] Further, a second push rod is fixedly connected inside the fixing column, a sliding column is fixedly connected to the output end of the second push rod, and the outer wall of the sliding column is slidably connected to the inner wall of the fixing column.
[0009] Further, a first motor is fixedly connected inside the sliding column, and a pulley is fixedly connected to the output end of the first motor.
[0010] Further, another pulley is rotatably connected inside the sliding column, and a conveyor belt is arranged on the outer wall of the pulley.
[0011] Further, a threaded rod is fixedly connected inside one of the pulleys, a fixed block is fixedly connected to the side wall of the sliding column, a fixing groove is opened inside the fixed block, a moving column is slidably connected inside the fixed block, and the side wall of the moving column is slidably connected inside the fixing groove.
[0012] Further, a support column is fixedly connected inside the moving column, a groove is opened inside the moving column, the outer wall of the support column is rotatably connected inside the groove, and the outer wall of the threaded rod is threadedly connected inside the support column.
[0013] Further, a second motor is fixedly connected to the side wall of the moving column, and a clamping plate is fixedly connected to the output end of the second motor.
[0014] The utility model has the following beneficial effects:
[0015] 1. In the present utility model, first, the slider is pushed by the first push rod. Since there is a chute inside the fixed plate and the slider is inside the chute, the slider starts to move, thereby driving the support block to move. Since both the support block and the support plate are equipped with rollers, the workpiece is adjusted by the rollers. Finally, fixation is achieved as the support block moves. Through the cooperation of the rollers, the support plate, and the support block, the effect of fixing workpieces of different specifications and sizes is achieved, solving the problem that the fixture cannot adapt to workpieces of different specifications, and improving the accuracy of workpiece positioning and the precision of workpiece processing.
[0016] 2. In the present utility model, the sliding column is pushed to move by the second push rod to complete the lifting and lowering of the sliding column. The output pulley of the first motor drives another pulley to rotate through the conveyor belt, and then drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the support column, and the support column is fixed in the inner groove of the moving column, and the fixed groove restricts the rotation of the moving column, the moving column moves, thereby driving the clamping plate to move. The output of the second motor drives the clamping plate to rotate. Through the cooperation of the first motor, the second motor, and the second push rod, the effect of driving the workpiece to rotate is achieved, solving the problem that it is not easy to adjust the workpiece during processing, and improving the processing efficiency and precision of the workpiece.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.
[0025] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: A tooling fixture includes a workbench 1. A fixing plate 8 is fixedly connected to the top of the workbench 1. A first push rod 2 is fixedly connected inside the fixing plate 8. The output end of the first push rod 2 is fixedly connected to a slider 3. A sliding groove 5 is formed inside the fixing plate 8. The side wall of the slider 3 is slidably connected inside the sliding groove 5. A support block 4 is fixedly connected to the top of the slider 3. A plurality of rollers 7 are rotatably connected to the inner wall of the support block 4. Symmetrically arranged support plates 6 are fixedly connected to the top of the fixing plate 8. Rollers 7 are rotatably connected inside both the support plates 6 and the support block 4. A fixing component is arranged on the top of the workbench 1, and the fixing component is used to fix the base 9 on the top of the workbench 1.
[0026] Specifically, the slider 3 is pushed by the first push rod 2. Since the sliding groove 5 is installed on the fixing plate 8 and the slider 3 is assembled in the sliding groove 5, therefore, as the first push rod 2 moves, the slider 3 starts to move slowly, which causes the support block 4 to move accordingly. The support plates 6 are installed on the fixing plate 8, and a plurality of rollers 7 are provided on both the support plates 6 and the support block 4. As the slider 3 moves, the rollers 7 start to adjust the position of the workpiece. At the same time, the movement of the support block 4 further fixes the workpiece, so that workpieces of different specifications can be effectively clamped, and the accuracy and stability during the workpiece processing are improved.
[0027] Referring to Figures 3 - 5, the fixing component includes a fixing column 10 which is fixedly connected to the top of the base 9. Inside the fixing column 10, a second push rod 11 is fixedly connected. The output end of the second push rod 11 is fixedly connected to a sliding column 12. The outer wall of the sliding column 12 is slidably connected to the inner wall of the fixing column 10. Inside the sliding column 12, a first motor 13 is fixedly connected. The output end of the first motor 13 is fixedly connected to a pulley 15. Another pulley 15 is rotatably connected inside the sliding column 12. A conveyor belt 14 is arranged on the outer wall of the pulley 15. Inside one of the pulleys 15, a threaded rod 16 is fixedly connected. A fixing block 21 is fixedly connected to the side wall of the sliding column 12. A fixing groove 23 is formed inside the fixing block 21. A moving column 17 is slidably connected inside the fixing block 21. The side wall of the moving column 17 is slidably connected inside the fixing groove 23. Inside the moving column 17, a support column 18 is fixedly connected. A groove 19 is formed inside the moving column 17. The outer wall of the support column 18 is rotatably connected inside the groove 19. The outer wall of the threaded rod 16 is threadedly connected inside the support column 18. A second motor 20 is fixedly connected to the side wall of the moving column 17. The output end of the second motor 20 is fixedly connected to a clamping plate 22.
[0028] Specifically, through the push of the second push rod 11, the sliding column 12 starts to move upward, thereby raising the height of the entire structure. Then, the first motor 13 outputs rotational force to the pulley 15, causing the pulley 15 to start rotating. The conveyor belt 14 connects the two pulleys 15. Therefore, when one pulley 15 rotates, the other will also rotate accordingly, which in turn drives the threaded rod 16 to start rotating. The threaded rod 16 is threadedly connected to the support column 18, and the moving column 17 limits the support column 18 through the groove 19. Since the fixing groove 23 inside the fixing block 21 restricts the rotation of the moving column 17, the rotation of the threaded rod 16 causes the movement of the moving column 17. The movement of the moving column 17 is transmitted to the clamping plate 22, resulting in the movement of the clamping plate 22 along the specified direction. Finally, the output of the second motor 20 causes the clamping plate 22 to start rotating, so that the position of the workpiece can be adjusted, thereby finely adjusting the position of the workpiece and improving the processing efficiency and processing accuracy of the workpiece.
[0029] Working principle: The slider 3 is pushed by the first push rod 2. Since the chute 5 is installed on the fixed plate 8 and the slider 3 is installed in the chute 5, as the first push rod 2 pushes, the slider 3 starts to gradually move, driving the support block 4 to move. Given that the support plate 6 is installed on the fixed plate 8 and there are multiple rollers 7 on both the support plate 6 and the support block 4, as the slider 3 moves, the rollers 7 start to adjust the workpiece. Thus, as the support block 4 gradually moves, the workpiece is further fixed, enabling the fixture to fix workpieces of different specifications, thereby improving the accuracy of workpiece processing. The height of the structure is increased by pushing the sliding column 12 with the second push rod 11. Then, the first motor 13 outputs the pulley 15, causing the pulley 15 to rotate. Since the conveyor belt 14 is connected to the two pulleys 15, the other pulley 15 also starts to rotate, driving the threaded rod 16 to rotate. The threaded rod 16 is threadedly connected to the support column 18, and the moving column 17 limits the support column 18 through the groove 19. Since the fixed block 21 restricts the rotation of the moving column 17 through the fixed groove 23, the threaded rod 16 drives the moving column 17 to move through its own rotation, and then drives the clamping plate 22 to move through the fixed block 21. Finally, the second motor 20 outputs the clamping plate 22, causing the clamping plate 22 to rotate, achieving the effect of driving the workpiece to rotate, further adjusting the position of the workpiece, and thus improving the efficiency and accuracy of workpiece processing.
[0030] 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. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
