Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, and in particular to a jig for surface texture processing. Background Technology

[0002] Some decorative items made of metal strips need to have patterns engraved on their surface after bending to enhance their visual appeal and highlight the design theme. Existing engraving methods either involve engraving on-site after installation, which requires disassembling and replacing most of the item if an error occurs, severely compromising the structural stability, or engraving followed by on-site assembly. However, due to the springback properties of metal, visual distortion can sometimes occur, placing extremely high demands on the engravers. Therefore, a device is needed that allows engraving while the item is bent, enabling on-site assembly after engraving, thus reducing the difficulty of engraving. Utility Model Content

[0003] The purpose of this invention is to provide a fixture for surface texture processing to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A surface texture processing fixture includes a second worktable. A receiving groove is provided at the top center of the second worktable. A driving device is fixedly installed inside the receiving groove. The driving device is composed of a motor and a reducer. The output shaft of the motor is connected to the input shaft of the reducer. The output shaft of the reducer is located at the top of the reducer body. A circular plate located on the top of the second worktable is sleeved on the output shaft of the reducer. There is a gap between the bottom of the circular plate and the top of the second worktable. A plurality of first through slots and a plurality of second through slots are uniformly arranged axially on the top of the circular plate. The circular plate is divided into an inner ring area and an outer ring area. The first through slots are located in the inner ring area, and the second through slots are located in the outer ring area. Both the first through slots and the second through slots are vertically connected.

[0006] By adopting the above technical solution, in actual use, four first through slots and three second through slots are required. A clamping module is installed in the first through slot, and a limiting rod is installed in the second through slot. The clamping module clamps the metal strip to be processed. Then, by adjusting the distance between the limiting rod in each second through slot and the center of the disc, the curvature of the bent metal strip changes, thereby achieving bending of the metal strip and surface texturing. Because metal has a certain yield strength, the metal will spring back when all the constraints are released after bending. Therefore, this device directly engraves the surface of the metal strip after bending to avoid text deformation (the text engraved after the constraints are released will deform during on-site installation).

[0007] In a further embodiment, a limiting rod is also included. The axis of the limiting rod is vertically arranged. The bottom end of the limiting rod passes through the second through groove and extends to the bottom of the circular plate. The bottom end of the limiting rod is set as a threaded surface. A first nut located at the bottom of the circular plate is screwed to the bottom end of the limiting rod. A clearance groove is provided at the inner top end of the second through groove. A second nut located in the clearance groove is also screwed to the bottom end of the limiting rod.

[0008] By adopting the above technical solution, the first nut and the second nut cooperate with each other to completely restrict the position of the limiting rod inside the second through groove.

[0009] In a further embodiment, the top of the second nut is provided with a plurality of through holes running vertically and uniformly.

[0010] By adopting the above technical solution, since the top surface of the second nut cannot extend beyond the second through groove, it is impossible to continue tightening the second nut with a conventional wrench after it has been screwed to a certain distance. At this time, a tweezer-like tool can be inserted into two circular holes symmetrical about the axis of the second nut, and then rotated to continue tightening the second nut. Alternatively, another method can be used: first screw the second nut to the bottom of the limiting rod at the designated position, then insert the bottom of the limiting rod into the second through groove, and then tighten the first nut with a wrench.

[0011] In a further embodiment, the bottom end of the second nut is provided with a washer coaxial with the limiting rod, and the top and bottom surfaces of the washer are both axially and uniformly provided with sharp protrusions.

[0012] By adopting the above technical solution, if the method of "first screwing the second nut to the designated position at the bottom of the limiting rod, then inserting the bottom end of the limiting rod into the second through groove, and then tightening the first nut with a wrench" is used, there needs to be friction between the bottom end face of the second nut and the inner wall of the through groove. Therefore, a shim is set to increase the friction.

[0013] In a further embodiment, the bottom of the circular plate is provided with a coaxial downward cylindrical protrusion, and a coaxial end face bearing is fixedly installed at the bottom of the cylindrical protrusion, with the bottom end face of the end face bearing in contact with the top end face of the second worktable.

[0014] By adopting the above technical solution, the disk can be prevented from tilting when pressure is applied.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. Four first through slots and three second through slots are required. A clamping module is installed in the first through slot, and a limiting rod is installed in the second through slot. The clamping module holds the metal strip to be processed. By adjusting the distance between the limiting rod in each second through slot and the center of the disc, the curvature of the bent metal strip changes, thereby achieving bending and surface texturing of the metal strip. Because metal has a certain yield strength, it will spring back when all constraints are released after bending. Therefore, this device directly engraves the surface of the metal strip after bending to avoid texturing deformation. It should be noted that because the texturing required on different product surfaces is different, a carving knife is used for manual engraving. This device is mainly to ensure that the texturing is done under the curvature of the product in the installation state. Attached Figure Description

[0023] Example 1:

[0024] like Figures 1-3 As shown, a surface texture processing fixture includes a second worktable 2. A receiving groove is provided at the center of the top of the second worktable 2. A driving device 3 is fixedly installed inside the receiving groove. The driving device consists of a motor and a reducer. The output shaft of the motor is connected to the input shaft of the reducer. The output shaft of the reducer is located at the top of the reducer body. A circular plate located on the top of the second worktable 2 is sleeved on the output shaft of the reducer. There is a gap between the bottom of the circular plate and the top of the second worktable 2. Multiple first through slots and multiple second through slots are evenly arranged axially on the top of the circular plate. The circular plate is divided into an inner ring area and an outer ring area. The first through slots are located in the inner ring area, and the second through slots are located in the outer ring area. Both the first and second through slots penetrate vertically. The device includes a limiting rod 4 with its axis vertically positioned. The bottom end of the limiting rod 4 passes through the second through groove and extends to the bottom of the circular plate. The bottom end of the limiting rod 4 is threaded, and a first nut 5 located at the bottom of the circular plate is screwed onto the bottom end of the limiting rod 4. A clearance groove is provided at the top inner end of the second through groove, and a second nut 6 located in the clearance groove is also screwed onto the bottom end of the limiting rod 4. The top of the second nut 6 has multiple through-holes evenly arranged axially. The bottom end of the second nut 6 has a washer 7 coaxial with the limiting rod 4, and sharp protrusions are evenly arranged axially on both the top and bottom surfaces of the washer 7. The bottom of the circular plate has a coaxial downward cylindrical protrusion, and a coaxial end face bearing is fixedly installed at the bottom of the cylindrical protrusion. The bottom surface of the end face bearing is in contact with the top surface of the second worktable.

[0025] Specific implementation process: Four first through slots and three second through slots are required. A clamping module is installed in the first through slot, and a limiting rod is installed in the second through slot. The clamping module holds the metal strip to be processed. Then, by adjusting the distance between the limiting rod in each second through slot and the center of the disc, the curvature of the bent metal strip changes, thereby achieving bending of the metal strip and surface texture engraving. Because metal has a certain yield strength, the metal will spring back when all the constraints are released after bending. Therefore, this device directly engraves the surface of the metal strip after bending, avoiding the effect of texture deformation.

[0026] Example 2:

[0027] Because the top surface of the second nut cannot extend beyond the second through groove, it cannot be tightened further with a regular wrench after the second nut has been screwed a certain distance. In this case, a tweezer-like tool can be inserted into two symmetrical holes about the axis of the second nut, and then rotated to continue tightening the second nut. Alternatively, another method can be used: first screw the second nut to the designated position at the bottom of the limiting rod, then insert the bottom of the limiting rod into the second through groove, and then tighten the first nut with a wrench. If the method of "first screwing the second nut to the designated position at the bottom of the limiting rod, then inserting the bottom of the limiting rod into the second through groove, and then tightening the first nut with a wrench" is used, there needs to be friction between the bottom surface of the second nut and the inner wall of the through groove. Therefore, a washer is used to increase friction. Conversely, if the first nut is installed first, the second nut also needs to be installed at the bottom of the limiting rod first, then the bottom of the limiting rod needs to be inserted into the second through groove, and then the first nut needs to be installed. After the first nut is in place, the second nut can be tightened. Once the strip is bent on top of the disc, the pattern can be manually engraved onto the surface of the strip using a carving knife. Since the patterns are not complex, manual engraving is more economical and flexible, allowing for the creation of different patterns according to the user's needs.

[0028] Example 3:

[0029] The technical solution of this application can also process sunburst patterns on the surface of a metal disc. When processing is required, the metal disc is placed on top of a disc. By adjusting the position of the limiting rods in the three second through holes, the metal disc is restricted to the center of the disc. Then, the drive motor rotates the disc, and the operator moves the engraving tool at a uniform speed in a centrifugal direction from the center to process the sunburst pattern on the surface of the metal disc. It should be noted that the cooperation between the drive motor and the reducer is to reduce the rotation speed of the disc to avoid being unable to react in time in case of danger due to excessive speed. Since it requires manual operation, the height of the limiting rods cannot be too high, and the operator's arms must not be covered with clothing when operating.

[0030] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.
