Description

Technical Field

[0001] This utility model belongs to the technical field of blade fork welding fixtures, specifically relating to a laser welding angle control fixture. Background Technology

[0002] Tooling refers to various equipment, tools, and devices used in industrial production processes to assist in production and improve efficiency. Tooling comes in a variety of forms and can include fixtures, molds, gauges, cutting tools, workstation fixtures, and other specialized equipment and tools used for machining, assembly, inspection, and handling. The design and use of tooling aim to improve production efficiency, ensure product quality, reduce labor intensity, and enhance safety. Based on their application, tooling can be categorized into general-purpose tooling and special-purpose tooling.

[0003] For some blade and shift fork welding fixtures, the existing control contouring fixtures are prone to wear after a period of production and use, which will lead to an increase in the contouring groove clearance and an unstable final angle. An unstable angle will cause the product workpiece to deviate, which will result in a decrease in welding accuracy. To address this, we propose a laser welding angle control fixture. Utility Model Content

[0004] The purpose of this invention is to provide a laser welding angle control fixture to solve the problem that the existing control contouring fixture mentioned in the background art is prone to wear after a period of production and use, which leads to an increase in the contouring groove gap, resulting in an unstable final angle. An unstable angle will cause the product workpiece to deviate, which in turn will cause a decrease in welding accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser welding angle control fixture, comprising a base, a fixing ring rotatably mounted on the upper surface of the base, a plurality of inclined slides arranged in a circular array on the lower surface of the inner wall of the fixing ring, rollers rotatably mounted on the inner wall of the inclined slides, a fixing pin mounted on the upper surface of the rollers, a fixing post fixedly mounted on the upper surface of the base, the fixing post being rotatably connected to the fixing ring, and the top end of the fixing post extending into the interior of the fixing ring and fixedly mounted with a tool. The worktable has several blade-shaped grooves and several straight slides. The blade-shaped grooves and straight slides at corresponding positions are interconnected. The fixed ejector pin is slidably installed on the inner wall of the straight slide at the corresponding position. A fixed plate is provided inside the fixed locking ring. A rotating plate is rotatably installed on the fixed plate. The fixed plate is located on the upper surface of the worktable. Both the fixed plate and the rotating plate have through holes for the shift fork to pass through, and the through holes are used in conjunction with the blade-shaped grooves. A cover plate is detachably installed on the upper surface of the fixed locking ring.

[0006] The above solution, using a fixed locking ring and workstation plate in conjunction with a fixed ejector pin and rollers, utilizes the rotation of the fixed locking ring to drive the rollers to roll within the inclined slide, which in turn drives the fixed ejector pin to move within the straight slide. This allows for the uniform and tight fixing of blades placed in the blade contour groove against the wall, ensuring the stability of the angle by fixing multiple blades at the same wall angle, unaffected by the size of the gap. This guarantees the stability of the angle, is convenient to operate, has a simple structure, and allows multiple blades to be simultaneously pressed and fixed, improving work efficiency.

[0007] In a preferred embodiment, a limiting wheel is fixedly installed on the outer surface of the roller, and a limiting groove is provided on the inner wall of the inclined slide for the limiting wheel to roll.

[0008] Using the above scheme, when the roller rolls in the inclined slide, it will drive the limiting wheel to roll synchronously in the limiting groove. The combination of the limiting groove and the limiting wheel can support the movement of the roller and prevent the roller from leaving the inclined slide.

[0009] In a preferred embodiment, an anti-slip rubber ring is attached to the outer surface of the fixing ring.

[0010] By adopting the above solution, the anti-slip rubber ring facilitates the operation of rotating the locking ring, avoids slippage during operation, and improves the stability of operation.

[0011] In a preferred embodiment, a fixing block is fixedly installed on the outer surface of the fixing ring, an adjusting locking rod is slidably installed on the fixing block, an adjusting disc is fixedly installed at the top of the adjusting locking rod, a spring is fixedly installed between the adjusting disc and the fixing block, and two adjusting locking sleeves that cooperate with the adjusting locking rod are fixedly installed on the surface of the base.

[0012] By adopting the above scheme, the adjusting lock rod is used in conjunction with the elastic force of the spring. When the adjusting lock rod is disengaged from the adjusting lock sleeve, the spring deforms, and at this time the fixed lock ring is unlocked and can be rotated to realize the fixed locking of the blade and the unlocking. The elastic force of the spring is used to drive the adjusting lock rod to quickly insert into the adjusting lock sleeve, improving the convenience of operation and locking.

[0013] In a preferred embodiment, the inner wall of the straight slide is provided with a sliding groove, and a sliding block is fixedly installed on the side of the fixed pin, the sliding block being slidably installed on the inner wall of the sliding groove.

[0014] By using the above solution, the sliding groove and the sliding block work together to ensure the stable movement of the fixed ejector pin and prevent the fixed ejector pin from shaking.

[0015] In a preferred embodiment, the inner wall of the fixing ring is fixedly installed with a locking protrusion, and the outer surface of the fixing plate is provided with a locking groove for the locking protrusion to engage.

[0016] By using the above solution, the positioning protrusions and positioning grooves can be used to limit the position of the fixed plate and prevent horizontal movement.

[0017] In a preferred embodiment, a plurality of locking screws are fixedly installed on the upper surface of the fixing ring, and a plurality of locking holes are provided on the cover plate. The locking screws pass through the locking holes and are threaded with locking nuts.

[0018] By using the above solution, the locking screw passes through the locking hole and is used in conjunction with the locking nut to achieve stable installation and locking of the cover plate. The locking structure is simple and easy to operate.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This laser welding angle control fixture uses a fixed locking ring and a work station plate in conjunction with a fixed ejector pin and rollers. The rotation of the fixed locking ring drives the rollers to roll in an inclined slide, which in turn drives the fixed ejector pin to move in a straight slide. This allows for the uniform and tight fixing of blades placed in the blade contour groove against the wall, ensuring the stability of the angle regardless of the gap size. The fixture is easy to operate, has a simple structure, and can simultaneously clamp and fix multiple blades, improving work efficiency. Attached Figure Description

The lower surface of the inner wall of the fixing ring 2 has several inclined slides 3 arranged in a ring array. Rollers 4 are rolled on the inner wall of the inclined slides 3. A fixing pin 5 is mounted on the upper surface of the roller 4. A fixing column 6 is fixedly mounted on the upper surface of the base 1. The fixing column 6 is rotatably connected to the fixing ring 2. The top of the fixing column 6 extends into the interior of the fixing ring 2 and is fixedly mounted on a work station plate 7. The work station plate 7 has openings... There are several blade contour grooves 8 and several straight slides 9. The blade contour grooves 8 and straight slides 9 at corresponding positions are interconnected. The fixed pin 5 is slidably installed on the inner wall of the straight slide 9 at the corresponding position. A fixed plate 10 is provided inside the fixed locking ring 2. A rotating plate 11 is rotatably installed on the fixed plate 10. The fixed plate 10 is located on the upper surface of the work station plate 7. Both the fixed plate 10 and the rotating plate 11 are provided with through holes for the shift fork to pass through, and the through holes are used in conjunction with the blade contour grooves 8. A cover plate 12 is detachably installed on the upper surface of the fixed locking ring 2.

[0030] By setting a fixed locking ring 2 and a work station plate 7 in conjunction with a fixed ejector pin 5 and a roller 4, the rotation of the fixed locking ring 2 drives the roller 4 to roll in the inclined slide 3, which in turn drives the fixed ejector pin 5 to move in the straight slide 9. This allows the blades placed in the blade contour groove 8 to be uniformly and tightly fixed against the wall, ensuring the stability of the angle of multiple blades against the wall, regardless of the size of the gap. This ensures the stability of the angle, is convenient to operate and use, has a simple structure, and allows multiple blades to be pressed and fixed at the same time, improving work efficiency.

[0031] A limiting wheel 13 is fixedly installed on the outer surface of the roller 4. A limiting groove 15 is provided on the inner wall of the inclined slide 3 for the limiting wheel 13 to roll. When the roller 4 rolls in the inclined slide 3, it will drive the limiting wheel 13 to roll synchronously in the limiting groove 15. The limiting groove 15 and the limiting wheel 13 can be used to support the movement of the roller 4 and prevent the roller 4 from leaving the inclined slide 3.

[0032] An anti-slip rubber ring 16 is attached to the outer surface of the fixing ring 2. The anti-slip rubber ring 16 facilitates the operation and rotation of the fixing ring 2, avoids slippage during operation, and improves the stability of operation.

[0033] A fixing block 17 is fixedly installed on the outer surface of the fixing ring 2. An adjusting locking rod 18 is slidably installed on the fixing block 17. An adjusting disc 19 is fixedly installed on the top of the adjusting locking rod 18. A spring 20 is fixedly installed between the adjusting disc 19 and the fixing block 17. Two adjusting lock sleeves that cooperate with the adjusting locking rod 18 are fixedly installed on the surface of the base 1. The adjusting locking rod 18 is used in conjunction with the elastic force of the spring 20. When the adjusting locking rod 18 is disengaged from the adjusting lock sleeve, the spring 20 deforms. At this time, the fixing ring 2 is unlocked and can be rotated to realize the fixing and locking of the blade and to release the lock. The elastic force of the spring 20 drives the adjusting locking rod 18 to quickly insert into the adjusting lock sleeve, improving the convenience of operation and locking.

[0034] The inner wall of the straight slide 9 is provided with a sliding groove 21, and a sliding block 14 is fixedly installed on the side of the fixed ejector pin 5. The sliding block 14 is slidably installed on the inner wall of the sliding groove 21. The sliding groove 21 and the sliding block 14 work together to ensure the stable movement of the fixed ejector pin 5 and prevent the fixed ejector pin 5 from shaking.

[0035] The inner wall of the locking ring 2 is fixedly installed with a locking protrusion 22, and the outer surface of the fixing plate 10 is provided with a locking groove for the locking protrusion 22 to be inserted. By using the locking protrusion 22 in conjunction with the locking groove, the position of the fixing plate 10 can be limited to avoid horizontal movement.

[0036] Several locking screws 23 are fixedly installed on the upper surface of the locking ring 2. Several locking holes are opened on the cover plate 12. The locking screws 23 pass through the locking holes and are threaded with locking nuts 24. By using the locking screws 23 passing through the locking holes and cooperating with the locking nuts 24, the cover plate 12 can be stably installed and locked. The locking structure is simple and easy to operate.

[0037] In use, unscrew the locking nut 24 to unlock the cover plate 12, pull it upwards to remove the cover plate 12, and then pull it upwards to remove the fixing plate 10. Then, insert the blades into the blade contour grooves 8 respectively. Pull the adjusting plate 19 to drive the adjusting locking rod 18 to move and disengage from the adjusting lock sleeve. At this time, the fixing locking ring 2 is unlocked. Rotate the fixing locking ring 2. When the fixing locking ring 2 rotates, it will drive the roller 4 to roll in the inclined slide 3, which in turn will drive the fixing pin 5 to move horizontally in the straight slide 9. Then, the fixing pin 5 will move closer to the blade to achieve the fixing and tightening of the blade. After fixing and tightening, release the adjusting plate 19 and use the elastic force of the spring 20 to drive the adjusting... The locking rod 18 is reset and inserted into the adjusting lock sleeve to achieve position locking, thereby ensuring that multiple blades are uniformly pressed against the wall to guarantee angular stability. Then, the fixing plate 10 is placed into the fixing lock ring 2 through the locking protrusion 22 and the locking groove.
