Description

Technical Field

[0001] The utility model relates to the technical field of positioning structures, and particularly relates to a positioning structure for an oil cylinder oil pipe welding tooling. Background Technique

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When using it to achieve reciprocating motion, a deceleration device can be omitted, and there is no transmission gap, and the motion is stable. Therefore, it is widely used in the hydraulic systems of various machines. In the production of hydraulic cylinders, two or more hydraulic cylinders need to be welded together by welding, and a positioning structure is required during the welding of hydraulic cylinders.

[0003] The commonly used positioning structure uses two clamping plates to clamp and position the hydraulic cylinder to be welded. Since the hydraulic cylinder is usually cylindrical, although the clamping plate can fix the position of the hydraulic cylinder to be welded, the clamping between the clamping plate and the hydraulic cylinder is a point clamping, and the clamping of the hydraulic cylinder by two points will make the clamped hydraulic cylinder not firm enough and is easy to break away from between the two clamping plates under force.

[0004] Therefore, we propose a positioning structure for an oil cylinder oil pipe welding tooling to solve the above problems. Content of the Utility Model

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment

[0028] As Figures 1-5 shown, a positioning structure for an oil cylinder oil pipe welding tooling proposed in an embodiment of the present utility model includes a workbench 1, and positioning and clamping assemblies are arranged on both sides of the upper end surface of the workbench 1. The positioning and clamping assemblies include a support plate 2 fixedly arranged on the workbench 1. A through hole is provided on the support plate 2. A fixing ring 3 is arranged on the support plate 2. A limit groove 4 is provided on the fixing ring 3. A limit rod 5 fixedly arranged on the support plate 2 is sequentially slidably arranged in the limit groove 4 on the fixing ring 3;

[0029] A plurality of fixed blocks 6 are fixedly arranged inside the fixing ring 3. Connecting plates 7 are rotatably arranged on the fixed blocks 6. A plurality of positioning clamping plates 8 are sequentially rotatably arranged on the support plate 2. The plurality of positioning clamping plates 8 are arranged in a circumferential array, and the plurality of positioning clamping plates 8 are located inside the fixing ring 3. One ends of the plurality of connecting plates 7 away from the fixed blocks 6 are respectively rotatably connected to the plurality of positioning clamping plates 8;

[0030] A transmission gear 9 is fixedly arranged on the outer wall surface of the fixed ring 3. A driving gear 10 is rotatably arranged on the support plate 2. The driving gear 10 meshes with the transmission gear 9 on the outer wall surface of the fixed ring 3. A servo motor 11 is fixedly arranged on the support plate 2, and the output end of the servo motor 11 is docked with the driving gear 10.

[0031] Through the setting of the positioning and clamping assembly, the oil cylinder oil pipe to be welded can be clamped at multiple points. This not only increases the stress area of the oil cylinder oil pipe to be welded, making the oil cylinder oil pipe to be welded more firmly positioned and clamped, and preventing the oil cylinder oil pipe to be welded from being disengaged from the positioning and clamping assembly due to external force, but also can be applied to oil cylinder oil pipes to be welded with different diameters.

[0032] A cleaning assembly is arranged between the two positioning and clamping assemblies. The cleaning assembly includes a moving plate 12 arranged on the workbench 1 and a sliding groove 13 opened on the workbench 1. A slider 14 is fixedly arranged on the lower end surface of the moving plate 12. The position of the slider 14 corresponds to that of the sliding groove 13, and the slider 14 is slidably arranged in the sliding groove 13. A vertical plate 15 is fixedly arranged on the moving plate 12, and a limiting ring 16 is fixedly arranged at the top end of the vertical plate 15. A plurality of cleaning sponges 17 are fixedly arranged in sequence in the limiting ring 16. An arc groove is opened at one end of each of the plurality of cleaning sponges 17, and the arc grooves at one end of the plurality of cleaning sponges 17 form a circular hole.

[0033] Through the setting of the cleaning sponge 17, the surface of the oil cylinder oil pipe to be welded passing through the cleaning sponge 17 can be cleaned. The setting of the sliding groove 13 and the slider 14 enables the cleaning sponge 17 to move along the sliding groove 13, which can increase the cleaning area at the contact part of the two ends of the two oil cylinder oil pipes to be welded. Since the cleaning sponge 17 has large elasticity, oil cylinder oil pipes to be welded with different diameters can all pass through.

[0034] A driving assembly is arranged on one side of the moving plate 12. The driving assembly includes a turntable 18 rotatably arranged on the workbench 1. A push-pull rod 19 is rotatably arranged on the turntable 18. The end of the push-pull rod 19 far from the turntable 18 is rotatably connected to the moving plate 12. A driving motor 20 is fixedly arranged in the workbench 1, and the output end of the driving motor 20 is docked with the turntable 18.

[0035] Through the setting of the driving assembly, it is used to drive the cleaning sponge 17 to move back and forth along the sliding groove 13, so as to clean the contact part of the two ends of the two oil cylinder oil pipes to be welded multiple times, making the contact part of the two oil cylinder oil pipes to be welded cleaner, and thus reducing the influence of more dust and impurities at the contact part of the two oil cylinder oil pipes to be welded on the welding firmness.

[0036] Working principle of this utility model:

[0037] Example 1: First, one end of each of the two oil cylinder pipes to be welded passes through the through holes on two support plates 2 respectively, and the ends of the two oil cylinder pipes to be welded are in contact with each other. The mutually contacting ends of the two oil cylinder pipes to be welded are inserted into the limit ring 16. Then, start the servo motor 11. The start of the servo motor 11 drives the driving gear 10 to rotate. The driving gear 10 drives the fixed ring 3 to rotate through the transmission gear 9. The rotation of the fixed ring 3 drives the fixed block 6 to rotate. The rotation of the fixed block 6 causes the connecting plate 7 to push the positioning clamping plate 8 towards the oil cylinder pipe to be welded until multiple positioning clamping plates 8 clamp the oil cylinder pipe to be welded. At this time, start the driving motor 20. The start of the driving motor 20 drives the turntable 18 to rotate. The rotation of the turntable 18 drives the rotation of the push-pull rod 19. The rotation of the push-pull rod 19 drives the moving plate 12 to move horizontally back and forth along the chute 13. The movement of the moving plate 12 drives the movement of the cleaning sponge 17. The movement of the cleaning sponge 17 will clean the contact area between the two oil cylinder pipes to be welded. After the contact area between the two oil cylinder pipes to be welded is cleaned, weld the contact area between the two welded oil cylinder pipes;

[0038] Example 2: Insert one end of the oil cylinder pipe to be welded through the through holes on two support plates 2 and the limit ring 16 in sequence. Then, start the servo motor 11. The start of the servo motor 11 drives the driving gear 10 to rotate. The driving gear 10 drives the fixed ring 3 to rotate through the transmission gear 9. The rotation of the fixed ring 3 drives the fixed block 6 to rotate. The rotation of the fixed block 6 causes the connecting plate 7 to push the positioning clamping plate 8 towards the oil cylinder pipe to be welded until multiple positioning clamping plates 8 clamp the oil cylinder pipe to be welded. Then, weld the oil cylinder pipe to be welded;

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
