Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, and more specifically, to a hardware processing fixture. Background Technology

[0002] In the hardware processing, fixtures are key process equipment for ensuring the machining accuracy of parts and improving production efficiency. They are mainly used to fix the workpiece, keep it in the correct position during processing, and withstand the cutting force and clamping force generated during processing, ensuring stable processing. According to the usage scenario, they can be divided into general-purpose fixtures, special-purpose fixtures, and fixtures designed and combined for specific parts. According to the driving method, they can be divided into manual fixtures, pneumatic fixtures, hydraulic fixtures, etc. The vise is one of the most commonly used general-purpose fixtures in hardware processing. It is mainly used to clamp flat, plate-shaped or block-shaped workpieces. The key components of the vise include the fixed vise body, the movable vise body, the lead screw, the nut and the jaws. When working, the workpiece is placed between the jaws. The self-locking characteristic of the lead screw generates a continuous clamping force to ensure that the workpiece does not shift during processing. The jaws are aligned with the reference surface of the workpiece to achieve positioning. Since the size of different batches of workpieces is different, it is necessary to perform clamping adjustment operations.

[0003] In related technologies, during the use of hardware fixtures, the adjustment force and clamping force are generally applied to the fixture by rotating the lead screw, so that the fixture can clamp and fix the workpiece for use.

[0004] However, in the current use of hardware fixtures, due to the influence of the screw rotation operation on the clamping space inside the fixture, when the clamping dimensions required for the first and second batches of workpieces differ significantly, the operator needs to continuously rotate the fixture to adjust the clamping space inside the fixture. This makes the operation of clamping workpieces cumbersome and inconvenient, affecting the flexibility and convenience of the fixture operation. Utility Model Content

[0030] Reference Figures 1-4 This utility model provides a technical solution: a hardware processing fixture, including a base 1 and a clamping and adjusting mechanism. A fixed plate 2 is installed on the right side of the top of the base 1, and a movable plate 3 is movably connected to the left side of the top of the base 1. The movable plate 3 and the base 1 can be quickly moved and adjusted for positioning, so that the user can quickly adjust the clamping space between the movable plate 3 and the fixed plate 2 according to the actual use needs, avoiding the situation where the movable plate 3 is difficult to adjust quickly during use. Therefore, the clamping operation flexibility and convenience of the movable plate 3 are improved.

[0031] Reference Figures 1-4 In a preferred embodiment, the clamping and adjusting mechanism includes an adjusting plate 4, which is movably connected to the left side of the movable plate 3. Adjusting slots 5 are provided on both sides of the top of the base 1. An adjusting frame 6 is fixedly connected to both sides of the left side of the adjusting plate 4. An adjusting bracket 7 is movably connected inside the adjusting frame 6. The adjusting connection mechanism is located on the top of the base 1. According to the actual clamping requirements of the external workpiece, the adjusting plate 4 is held by hand to move the movable plate 3, adjusting the clamping space between the movable plate 3 and the fixed plate 2. After the movable plate 3 is adjusted, the adjusting bracket 7 is moved downwards into the adjusting slot 5. At this time, the adjusting bracket 7, in conjunction with the adjusting frame 6 and the adjusting slot 5, performs insertion and positioning work between the adjusted adjusting plate 4 and the base 1, so that the operator can then... The movable plate 3 is then used for fine-tuning to clamp the workpiece. The adjustment and connection mechanism includes an adjustment cavity 8, an adjustment seat 9, and an adjustment block 10. The adjustment cavity 8 is located on the top left side of the base 1. The adjustment seat 9 is fixedly connected to the bottom of the adjustment plate 4, and the adjustment block 10 is fixedly connected to the bottom of the movable plate 3. Both the adjustment seat 9 and the adjustment block 10 are located inside the adjustment cavity 8. This mechanism can adjust and connect the adjustment plate 4, the movable plate 3, and the base 1 to prevent misalignment. It also guides the adjustment plate 4 and the movable plate 3 during the adjustment process, allowing the user to adjust the adjustment plate 4 and the movable plate 3 and preventing positional misalignment during use. This improves the smoothness and stability of the adjustment operation of the adjustment plate 4 and the movable plate 3.

[0032] Reference Figures 2-4In a preferred embodiment, a screw hole 11 is provided on the left side of the adjusting seat 9, and a stud 12 is threadedly connected inside the screw hole 11. A crank handle 13 is fixedly connected to the left side of the stud 12. This allows the adjusting plate 4 to provide clamping force and fine-tuning force to the movable plate 3, avoiding the situation where the adjusting plate 4 has difficulty providing clamping force to the movable plate 3 during use. Therefore, the force application effect between the adjusting plate 4 and the movable plate 3 is improved. A movable hole 14 is provided on the left side of the adjusting block 10, and a movable head 15 located inside the movable hole 14 is fixedly connected to the right side of the stud 12. This allows the stud 12 and the adjusting block 10 to rotate and connect, avoiding the situation where the stud 12 has difficulty applying threaded thrust to the movable plate 3 during use. Therefore, the connection effect between the stud 12 and the adjusting block 10 is improved.

[0033] Reference Figures 2-4 In a preferred embodiment, a screw groove 16 is provided on the right side of the movable head 15, and a screw 17 located on the right side of the adjusting block 10 is connected to the internal thread of the screw groove 16. This can restrict the connection between the movable head 15 and the movable hole 14 to prevent separation, thus preventing the stud 12 from detaching from the adjusting block 10 during use. Therefore, the connection stability between the stud 12 and the adjusting block 10 is improved. A receiving groove 18 is provided on the right side of the inner wall of the adjusting cavity 8. The size of the receiving groove 18 is adapted to the size of the screw 17, which can provide a space for the screw 17 to move and accommodate. This prevents the screw 17 from directly contacting the side wall of the adjusting groove 5 and restricting the movable plate 3, which would make it difficult for the movable plate 3 to cooperate with the fixed plate 2 to clamp the thin plate workpiece. Therefore, the operation and accommodating effect of the screw 17 is improved.

[0034] Reference Figures 2-3 In a preferred embodiment, magnetic grooves 19 are provided on both sides of the left side of the adjustment frame 7, and magnetic strips 20 are fixedly connected to the inner wall of the magnetic grooves 19. This allows for magnetic positioning between the adjustment frame 7 and the adjustment frame 6 during the adjustment process, avoiding difficulties in positioning the adjustment frame 7 during operation. This improves the ease of operation of the adjustment frame 7. A magnetic cavity 21 is provided on the left side of the inner wall of the adjustment frame 6, and a magnetic strip 22 that is magnetically connected to the magnetic strip 20 is fixedly connected to the inner wall of the magnetic cavity 21. This provides a medium for applying magnetic positioning force to the magnetic strip 20, avoiding difficulties in effectively applying magnetic positioning force when using the magnetic strip 20. This improves the magnetic positioning effect of the magnetic strip 20.

[0035] Specifically, the working process or principle of this hardware processing fixture is as follows: When in use, the hardware workpiece to be clamped is placed on top of the base 1, with the workpiece positioned inside the fixed plate 2 and movable plate 3. Based on the required clamping space according to the actual size of the workpiece, the hand-held adjusting plate 4 moves the stud 12 via the adjusting seat 9 and screw hole 11. At this time, the stud 12, through the movable head 15 and movable hole 14, engages with the adjusting block 10, causing the movable plate 3 to move synchronously with the adjusting plate 4, performing a preliminary adjustment of the clamping space between the movable plate 3 and the fixed plate 2. Simultaneously, the adjusting seat 9 and adjusting block 10 move with the adjusting plate 4 and movable plate 3 within the adjusting cavity 8, adjusting the connection and guiding anti-deviation work between the adjusting plate 4, movable plate 3, and base 1. During this process, the adjusting frame 7 moves with the adjusting plate 4 via the adjusting frame 6. Simultaneously, the magnetic strip 20, in conjunction with the magnetic suction strip 22, performs magnetic positioning work between the adjusting frame 7 and the adjusting frame 6. After the adjusting plate 4 is adjusted, the hand-held adjusting plate 4... The adjusting frame 7 moves downward into the adjusting groove 5, allowing it to engage with the adjusting groove 5 and the adjusting frame 6 to perform insertion and positioning between the adjusted plate 4 and the base 1. At this time, the magnetic strip 20, in conjunction with the magnetic suction strip 22, magnetically positions and stabilizes the adjusted frame 7 and the adjusting frame 6. Subsequently, the hand crank rotates the stud 12, engaging with the screw hole 11 and the movable head 15, causing the stud 12 to apply a rightward threaded thrust to the movable plate 3 through the adjusting block 10. This causes the movable plate 3 to engage with the fixed plate 2 to clamp the workpiece. Since the screw 17 is threadedly connected to the movable head 15 through the screw groove 16, it forms an I-shaped connecting shaft on the outside of the adjusting block 10 through the movable hole 14, allowing for rotational connection between the stud 12 and the adjusting block 10 to prevent separation. Simultaneously, when the workpiece is a thin plate, the screw 17 moves to the right along with the stud 12 into the receiving groove 18, ensuring that the movable plate 3 can move fully to the right to clamp the thin plate workpiece.
