Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing technology, and in particular to a metal processing fixture that is easy to adjust. Background Technology
[0002] A fixture is a tool used to fix a workpiece so that it can be processed smoothly. Fixtures are one of the essential tools in machining. The quality of a fixture is directly related to the quality of workpiece processing. The quality of a fixture is reflected in the clamping effect on the workpiece, the ease of use of the fixture, and the service life of the fixture.
[0003] Existing technology components for metalworking fixtures typically include the following:
[0004] 1. Clamps or chucks: These directly contact the metal workpiece and apply clamping force;
[0005] 2. Lead screw or screw rod: Used to transmit power and realize the opening, closing or movement of the grippers;
[0006] 3. Handle or wheel: Used for manually operating the lead screw or screw to apply clamping force;
[0007] 4. Base or bracket: Provides the structure to support and secure the entire clamp;
[0008] 5. Slider or slide rail: Guides the movement of the gripper or other moving parts to ensure smooth and accurate movement;
[0009] 6. Fastening bolts or nuts: used to secure and adjust the various components of the clamp;
[0010] 7. Pads or shims: Increase clamping friction or protect the workpiece surface;
[0011] 8. Locating pins or locating blocks: used to determine the position of the workpiece in the fixture;
[0012] When using the fixture, install it on the worktable of the processing equipment, ensuring that the installation is firm and stable. Then, according to the shape and size of the metal workpiece to be processed, adjust the position of the clamping jaws of the fixture or replace the appropriate chuck. Manually turn the handle or the rotary wheel, and through the transmission of the lead screw or screw, move the jaws toward the center and gradually approach the workpiece. When the jaws contact the workpiece, continue to turn the handle to apply sufficient clamping force to ensure that the workpiece is firmly fixed and will not move or shake during the processing.
[0013] However, traditional clamping fixtures are often complicated and cumbersome to use when clamping and fixing metals. They are difficult to quickly and accurately fix metal workpieces in multiple directions. The fixtures are not very versatile for metals of different sizes and shapes, and require frequent replacement or adjustment of fixture components, which increases preparation time and cost.

[0035] This application provides an easily adjustable metalworking fixture, effectively solving the problems of traditional fixtures which are often complex and cumbersome to operate when clamping and fixing metal, making it difficult to quickly and accurately fix metal workpieces in multiple directions. Furthermore, the fixtures have poor versatility for metals of different sizes and shapes, requiring frequent replacement or adjustment of fixture components, increasing preparation time and cost.

It is adaptable to metals of different sizes, has strong versatility, and reduces the hassle of changing fixtures due to differences in metal size.
[0036] Example
[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problems of traditional fixing fixtures, which are often complicated and cumbersome to operate when clamping and fixing metal, making it difficult to quickly and accurately achieve effective fixation of metal workpieces in multiple directions. Furthermore, the fixtures have poor versatility for metals of different sizes and shapes, requiring frequent replacement or adjustment of fixture components, increasing preparation time and cost. The overall idea is as follows: A metal processing fixing fixture that is easy to adjust includes a processing table 11. First vertical plates 12 are symmetrically fixedly installed on the upper end of the processing table 11. Rotating shafts 13 are rotatably installed inside the two first vertical plates 12. Threaded rings 14 are symmetrically threaded on the rotating shafts 13. Springs 15 are fixedly installed on the opposite ends of the two threaded rings 14. Wedge-shaped extrusion plates 16 are fixedly installed on the opposite ends of the two springs 15. Circular grooves are opened on the two wedge-shaped extrusion plates 16. The rotating shaft 13 is located in the two circular grooves. Insert pins 17 are symmetrically fixedly installed on the opposite ends of the two wedge-shaped extrusion plates 16. The two sets of insert pins 17 are slidably installed in the two threaded rings 14.
[0038] A placement mechanism is provided at the upper end of the processing table 11;
[0039] The placement mechanism includes two second vertical plates 21, which are symmetrically fixedly installed on the processing table 11. Each of the two second vertical plates 21 has a groove 22 inside, and a slide plate 23 is slidably installed inside each groove 22. Each slide plate 23 has a threaded screw 24 inside, with the opposite ends of the screws 24 rotatably installed in the two second vertical plates 21. Each slide plate 23 has a symmetrically formed column groove 25. Each slide plate 23 has a placement platform 26 at its upper end, and each placement platform 26 has a symmetrically fixed limit post 27 at its lower end. The two sets of limit posts 27 are slidably installed in the two sets of column grooves 25. In use, the metal to be processed can be placed on the two placement platforms 26, and then the two screws 24 can be rotated on the two slide plates 23. With the rotation of the two screws 24, the two slide plates 23 will move within the two grooves 22. The relative movement of the two slide plates 23 will cause the two placement tables 26 to move relative to each other. The movement of the two placement tables 26 will limit the left and right ends of the metal to be processed. Then, the rotating shaft 13 can be rotated inside the two first vertical plates 12. The rotation of the rotating shaft 13 will drive the threaded ring 14, spring 15 and wedge extrusion plate 16 to rotate accordingly. The rotation of the wedge extrusion plate 16 will contact the front and rear ends of the metal to be processed. After being subjected to force, the two wedge extrusion plates 16 will slide towards both ends on the rotating shaft 13. At this time, the two wedge extrusion plates 16 will drive the two inserts 17 to slide inside the two threaded rings 14. At this time, the two springs 15 will be compressed, so that the equipment can achieve precise limiting of the metal to be processed during use, ensuring its stable position during processing and improving processing accuracy and quality.
[0040] To address the problems existing in the prior art, this utility model provides an easily adjustable metal processing fixture. This device can achieve precise positioning of the metal to be processed, ensuring its stable position during processing and improving processing accuracy and quality. It is adaptable to metals of different sizes, has strong versatility, and reduces the trouble of changing fixtures due to differences in metal size.
[0041] Working principle:
[0042] In operation, the metal to be processed is first placed on two placement platforms 26. Then, two screws 24 are rotated on two sliding plates 23. The rotation of the screws 24 causes the two sliding plates 23 to move relative to each other within the two sliding grooves 22. This movement of the sliding plates 23 causes the two placement platforms 26 to move relative to each other, thus limiting the left and right ends of the metal to be processed. Then, a rotating shaft 13 is rotated inside the two first vertical plates 12. The rotation of the shaft 13 causes the threaded ring 14, spring 15, and wedge-shaped extrusion plates 16 to rotate accordingly. The rotation of the wedge-shaped extrusion plates 16 causes them to contact the front and rear ends of the metal to be processed. Under pressure, the two wedge-shaped extrusion plates 16 slide towards both ends on the rotating shaft 13. At this time, the two wedge-shaped extrusion plates 16 cause the two inserts 17 to slide within the two threaded rings 14. The two springs 15 are then compressed, enabling the device to achieve precise limiting of the metal to be processed during use, ensuring its stable position during processing, and improving processing accuracy and quality.
[0043] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
