Description

Technical Field

[0001] This utility model belongs to the field of aluminum processing equipment, and in particular relates to a splicing fixture and an aluminum surface wire drawing device. Background Technology

[0002] Aluminum surface brushing equipment is a device that processes straight lines onto the surface of aluminum through mechanical friction or extrusion, aiming to enhance the visual appeal and tactile feel of aluminum. It is widely used in architectural hardware, digital product casings, and other fields. Existing devices typically use cylinder-driven clamps to hold the aluminum material from both sides, and a worktable moves the aluminum material upwards, bringing its surface into contact with brushing components (such as brushing wheels or abrasive belts) for brushing. For example, some devices use cylinders to push sliding frames and strip pushers to fix the aluminum material from both sides, while the worktable rises and falls to achieve contact between the aluminum material and the brushing rollers. However, this design relies on the clamping height of the clamps on the sides of the aluminum material. When processing shorter aluminum materials, their upper surface may be below the minimum clamping plane of the clamps, preventing the brushing components from effectively contacting the aluminum surface and thus failing to complete the brushing operation. This limitation significantly reduces the equipment's adaptability to different aluminum material specifications, restricting its application range. Therefore, there is an urgent need to optimize the clamping structure or worktable positioning mechanism to expand the device's compatibility with shorter aluminum materials. Summary of the Invention

[0003] In view of the above-mentioned problems in the existing technology, the present invention provides a splicing clamp, which includes a clamping cylinder, a connecting frame, an upper clamp and a lower clamp. The upper clamp is spliced ​​and installed above the lower clamp, and the upper clamp and the lower clamp are respectively fixedly installed to the output end of the clamping cylinder through the connecting frame.

[0004] The telescopic rod of the clamping cylinder is threaded, and a fastening ring is installed on the telescopic rod via the threaded connection. A T-shaped slot is symmetrically provided on the upper and lower parts of the end of the telescopic rod away from the clamping cylinder. The connecting frame includes a base plate, with a protruding connecting part in the middle. A T-shaped locking block matching the T-shaped slot is provided on one side of the connecting part. The outer side of the T-shaped locking block is an arc surface with the same curvature as the telescopic rod. Several triangular support frames are provided on the side of the base plate with the connecting part. The connecting frame is installed onto the telescopic rod through the interlocking of the T-shaped locking block and the T-shaped slot. The upper clamp and lower clamp are fixedly installed onto the corresponding triangular support frames of the connecting frame.

[0005] Wherein, the fastening ring is larger than the T-shaped slot, and when the T-shaped block is embedded into the T-shaped slot, the fastening ring can be operably moved to completely cover the T-shaped block and the T-shaped slot.

[0006] The upper clamp has a limiting protrusion on its lower surface, which extends along the length of the upper clamp. The lower clamp has a limiting groove on its upper surface that matches and is inserted into the limiting protrusion, which extends along the length of the lower clamp. When the upper clamp is spliced ​​and installed onto the lower clamp, the limiting protrusion is inserted into the limiting groove. The lower clamp has a slider on its lower surface.

[0007] This utility model also provides an aluminum surface wire drawing device, which is equipped with the splicing fixture as described above. Specifically, it includes a frame, an operating cavity, a worktable that slides up and down in the operating cavity, a lifting component that drives the worktable to rise or fall at the bottom of the frame, a wire drawing component that is installed on the top of the operating cavity of the frame, and the splicing fixture is installed on the upper surface of the worktable.

[0008] The frame is fixedly equipped with an air pipe tension adjustment structure above the clamping cylinder, and a dust suction component is provided on one side of the operating chamber at the corresponding wire drawing component.

[0009] The beneficial effects of this invention are as follows: The fixture is disassembled into a connectable upper fixture and a lower fixture, which are integrated into the output end of the clamping cylinder via a connecting frame. When processing tall aluminum materials, the upper and lower fixtures are joined together to provide sufficient clamping height; while for short aluminum materials, the upper fixture and corresponding connecting frame can be removed separately, leaving only the lower fixture for clamping. This effectively avoids the problem of the fixture structure being too tall and obstructing the contact between the aluminum surface and the wire drawing components, expanding the applicability of the equipment, reducing downtime caused by fixture replacement, and improving production efficiency.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] Example 1: A splicing fixture.

[0019] As attached Figure 1-5 The illustrated splicing clamp includes a clamping cylinder 1, two connecting frames 2, an upper clamp 3, and a lower clamp 4. The telescopic rod 5 of the clamping cylinder 1 is threaded, and a fastening ring 6 is threadedly connected to the telescopic rod 5. A T-shaped slot 7 is symmetrically provided at the upper and lower parts of the end of the telescopic rod 5 away from the clamping cylinder 1. The T-shaped vertical rod of the T-shaped slot 7 is parallel to the telescopic rod 5 and extends to the end of the telescopic rod 5. The connecting frame 2 includes a base plate 8. A raised connecting part 9 is provided in the middle of the plate 8. A T-shaped locking block 10 matching the T-shaped slot 7 is provided on one side of the connecting part 9. The outer side of the T-shaped locking block 10 is an arc surface with the same curvature as the telescopic rod 5. The fastening ring 6 is larger than the T-shaped slot 7. When the T-shaped locking block 10 is inserted into the T-shaped slot 7, the fastening ring 6 can be operably moved to completely cover the T-shaped locking block 10 and the T-shaped slot 7. Since the outer side of the T-shaped locking block 10 is an arc surface, it is inserted into the T-shaped slot 7. The connecting rod 2 and the telescopic rod 5 can be combined to form a complete cylindrical shape, and the cylindrical structure matches the fastening ring 6, so that the fastening ring 6 can be fitted with the T-shaped locking block 10 and the T-shaped locking groove 7. The base plate 8 has two triangular support frames 11 on the side with the connecting part 9. The connecting frame 2 is installed to the telescopic rod 5 through the interlocking of the T-shaped locking block 10 and the T-shaped locking groove 7. The upper clamp 3 and the lower clamp 4 are fixedly installed to the triangular support frames 11 of the corresponding connecting frame 2 by bolts. The lower surface of the upper clamp 3 is provided with a limiting protrusion 12, which extends along the length direction of the upper clamp 3. The upper surface of the lower clamp 4 is provided with a limiting groove 13 that matches the limiting protrusion 12 and extends along the length direction of the lower clamp 4. The upper clamp 3 is spliced ​​and installed above the lower clamp 4, and when the upper clamp 3 is spliced ​​and installed above the lower clamp 4, the limiting protrusion 12 is inserted into the limiting groove 13. The lower surface of the lower clamp 4 is provided with a slider 14.

[0020] When it is necessary to disassemble or assemble the upper clamp 3, the fastening ring 6 can be tightened first. The fastening ring 6 moves towards the clamping cylinder 1 and exposes the position corresponding to the T-shaped slot 7. At this time, the upper clamp 3 and its corresponding connecting frame 2 can be removed or installed. Then, the fastening ring 6 is tightened again, causing the fastening ring 6 to move towards the connecting frame 2 and cover the position corresponding to the T-shaped slot 7 again, thereby locking the T-shaped block 10 in the T-shaped slot 7 and completing the fixed connection of the connecting frame 2. Therefore, the upper clamp 3 can be disassembled and installed simply by tightening the fastening ring 6, which is simple to operate and reduces downtime caused by changing clamps.

[0021] Example 2: A wire drawing device for aluminum materials.

[0022] As attached Figure 1-7 The aluminum surface brushing device shown includes a frame 15 with support legs 16 on both sides. The frame 15 has an operating cavity 17, within which a worktable 18 is slidably mounted. A mounting plate 19 is located at the bottom of the frame 15, and a lifting motor 20 is fixedly mounted on the mounting plate 19. A lifting screw 21 is fixedly mounted at the output end of the lifting motor 20, threadedly connected to the bottom of the frame 15. The top of the lifting screw 21 is rotatably connected to the bottom of the worktable 18. A lifting guide rod 22 is symmetrically fixedly mounted on each side of the lifting screw 21 at the bottom of the worktable 18. The lifting guide rods 22 pass through the bottom of the frame 15 and are fixedly connected to the mounting plate 19, and slidably connected to the bottom of the frame 15. The lifting motor 20, mounting plate 19, lifting screw 21, and lifting guide rods 22 constitute a lifting assembly 23 that drives the worktable 18 to rise or fall.

[0023] A wire drawing assembly 24 is mounted on the top of the operating chamber 17 on the frame 15. The wire drawing assembly 24 includes a mounting frame 25, in which pressure rollers are fixedly mounted. The pressure rollers are connected to the wire drawing motor 26. The same wire drawing abrasive belt 27 is fitted onto the outer surface of all pressure rollers. The wire drawing motor 26 drives the wire drawing abrasive belt 27 to rotate and perform wire drawing operations. A dust collection assembly 28 is provided on one side of the operating chamber 17 at the corresponding location of the wire drawing assembly 24. The dust collection assembly 28 adopts a conventional dust collection assembly used in metal processing. A set of spliced ​​clamps 29 is mounted on each side of the upper surface of the worktable 18. A guide rail 30 is provided on the worktable 18. The lower clamp 4 is slidably mounted on the worktable 18 through the cooperation of the slider 14 and the guide rail 30. The two sets of spliced ​​clamps 29 are driven by the clamping cylinder 1 to bring the corresponding clamps closer together and clamp and fix the wire drawing object.

[0024] In this embodiment, the aluminum surface drawing device first determines whether the upper clamp 3 is needed based on the actual height of the aluminum material. Then, by tightening the fastening ring 6 and removing or installing the upper clamp 3, the small aluminum material to be drawn is placed on the worktable 18. The two clamping cylinders 1 are started simultaneously and drive the clamp to clamp the aluminum material. Then, the lifting motor 20 is started and drives the worktable 18 to rise. After the worktable 18 lifts the aluminum material to a suitable position, the drawing motor 26 is started and drives the drawing sand belt 27 to rub and draw the aluminum material surface. At the same time, the dust collection equipment is started to suck the aluminum powder generated by the drawing into the dust collection box until the drawing is completed.

[0025] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
