Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a positioning device for intermediate connecting pieces of welding fixtures. Background Technology

[0002] The intermediate connecting piece positioning device in welding fixtures is a key component used for precise positioning of intermediate connecting pieces. Based on the six-point positioning principle, it restricts the degree of freedom of the connecting piece through mechanical structure, ensuring that the position is fixed during welding, guaranteeing welding accuracy and quality, improving production efficiency, and reducing labor intensity.

[0003] When welding the connectors, the worker first takes the connector and uses a jig to precisely lift it to the positioning point to ensure accurate positioning. Then, holding the welding gun, the worker aligns it with the connection and turns on the equipment to perform manual welding. During the welding process, continuous observation is required to ensure that the weld is uniform. After welding, the jig is removed and the welding quality is checked. The entire process relies on manual operation and experience control.

[0004] The existing technology has the following drawbacks: the traditional welding fixture positioning process relies on manual use of jigs to lift the connecting parts and then perform manual welding. This operation method has the problems of cumbersome process, high labor intensity, and low efficiency of manual operation, which makes it difficult to meet the needs of large-scale production and becomes a bottleneck restricting the improvement of welding production efficiency. To solve the above problems, a welding fixture intermediate connecting piece positioning device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a positioning device for intermediate connecting pieces of welding fixtures, which aims to improve the problem of inaccurate positioning in manual operation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a positioning device for intermediate connecting pieces of welding fixtures, comprising a worktable, a slide rail fixedly connected to the top of the worktable, a bracket slidably connected to the outer wall of the slide rail, a fixing plate fixedly connected to the top of the worktable, a main body component placed on the top of the worktable, a connecting piece provided on the inner wall of the main body component, a moving rod fixedly connected to the right side wall of the bracket, an movable mechanism provided on the inner wall of the moving rod, and a limit component provided on the top of the worktable;

[0007] The movable mechanism includes a top block, which is slidably connected to the inner wall of the moving rod, and the bottom end of the top block is elastically connected to the moving rod through a movable spring.

[0008] As a further description of the above technical solution:

[0009] The limiting component includes a guide rod, which is fixedly connected to the top of the worktable. A slider is slidably connected through the outer wall of the guide rod. An extrusion groove is formed on the inner wall of the slider. A long rod is slidably connected to the inner wall of the extrusion groove. A stop bar is fixedly connected to the outer wall of the slider.

[0010] As a further description of the above technical solution:

[0011] The right sidewall of the fixing plate is in contact with the left sidewall of the main body.

[0012] As a further description of the above technical solution:

[0013] The upper part of the top block is provided with an arc-shaped surface, and the outer side of the top block is provided with a protrusion.

[0014] As a further description of the above technical solution:

[0015] The top of the top block is in contact with the inner wall of the connector.

[0016] As a further description of the above technical solution:

[0017] The left sidewall of the stop bar is in contact with the right sidewall of the connector.

[0018] As a further description of the above technical solution:

[0019] The left end of the extrusion groove is inclined, and the right end of the extrusion groove is horizontal.

[0020] As a further description of the above technical solution:

[0021] The long rod is fixedly connected to the right side wall of the bracket.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the support is moved by the electric control slide rail, and the automatic positioning of the connecting parts on the main body is achieved by the cooperation of the long rod and the extrusion groove, as well as the linkage of the top block and the movable spring. This replaces the tedious operation of manual welding after lifting with a jig, reduces labor intensity, and improves welding efficiency.

[0024] 2. In this utility model, while the top block fixes the connector, the stop bar moves down simultaneously to block the connector, forming a lateral obstruction. This effectively prevents the connector from shifting due to the movement of the top block during the positioning process, ensuring the accurate position of the connector during welding and guaranteeing the welding quality.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a welding fixture intermediate connecting piece positioning device, including a workbench 1, which supports the entire device. A slide rail 2, also known as a guide rail or linear guide rail, is fixedly connected to the top of the workbench 1. This slide rail 2 is a strip-shaped component fixed to equipment or structure, providing guidance and support for a support 3, enabling it to move linearly along a fixed direction. The support 3 is slidably connected to the outer wall of the slide rail 2. A fixing plate 4 is fixedly connected to the top of the workbench 1. A main body 5 is placed on the top of the workbench 1, and a connecting piece 6 is provided on the inner wall of the main body 5. Both component 6 and main component 5 are configured such that the front end is higher than the rear end. A movable rod 7 is fixedly connected to the right side wall of the bracket 3. An active mechanism is provided on the inner wall of the movable rod 7. A limit component is provided at the top of the worktable 1. The active mechanism includes a top block 9, which is slidably connected to the inner wall of the movable rod 7. A slot corresponding to the top block 9 is opened on the movable rod 7, so that the top block 9 can move vertically. The bottom end of the top block 9 is elastically connected to the movable rod 7 through an active spring 8. When the top block 9 moves downward, the active spring 8 is compressed. When resetting, the elastic force of the active spring 8 is used to reset the top block 9.

[0034] Reference Figures 1-3 The limiting component includes a guide rod 13, which is fixedly connected to the top of the worktable 1. A slider 11 is slidably connected through the outer wall of the guide rod 13. The guide rod 13 guides and connects the slider 11. An extrusion groove 12 is provided on the inner wall of the slider 11. A long rod 10 is slidably connected to the inner wall of the extrusion groove 12. When the long rod 10 extrudes the inclined section of the extrusion groove 12, the slider 11 moves downward. A stop rod 14 is fixedly connected to the outer wall of the slider 11. The left side wall of the stop rod 14 contacts the right side wall of the connector 6. The stop rod 14 blocks and limits the connection of the connector 6. The left end of the extrusion groove 12 is inclined, and the right end of the extrusion groove 12 is horizontal. The long rod 10 is fixedly connected to the right side wall of the bracket 3.

[0035] Reference Figures 3-5 The right sidewall of the fixing plate 4 contacts the left sidewall of the main body 5. The fixing plate 4 acts as a shield and limit for the main body 5, ensuring that the connecting piece 6 is in the same position each time it is placed. The upper part of the top block 9 is provided with an arc-shaped surface. When the connecting piece 6 presses the arc-shaped surface of the top block 9, the top block 9 moves downward. The top of the top block 9 contacts the inner wall of the connecting piece 6. The top block 9 provides support for the connecting piece 6. The outer side of the top block 9 is provided with a protrusion.

[0036] Working principle: When welding connector 6 is required, manually place connector 6 in the middle of main body 5, then place main body 5 on workbench 1 so that the left side wall of main body 5 contacts fixed plate 4. Then, through external electric control slide rail 2, bracket 3 moves to the right with moving rod 7 and long rod 10. As long rod 10 moves to the right, it will squeeze the inclined section of extrusion groove 12, causing slider 11 to move downward with stop rod 14. When stop rod 14 moves to contact the right side wall of connector 6, long rod 10 enters... In the horizontal section of slider 11, the long rod 10 no longer presses against the extrusion groove 12. At the same time, the top block 9 contacts the connector 6. The connector 6 will press against the arc-shaped surface of the top block 9, causing the top block 9 to move downward and press against the movable spring 8. As the top block 9 moves to the right, the top block 9 moves upward under the reverse elastic force of the movable spring 8. The top block 9 will abut against the lower side of the connector 6, so that the connector 6 is in a fixed position. There is no need to manually lift it with a jig and then manually weld it. At the same time, the stop rod 14 will block the connector 6 when the top block 9 moves, preventing the connector 6 from moving to the right of the top block 9.

[0037] Next, the staff can weld the connector 6 to the main body 5. After welding, the electric control bracket 3 moves to the left. As the bracket 3 moves to the left with the long rod 10 and the moving rod 7, the connector 6 stops pressing the top block 9. Under the elastic force of the movable spring 8, the top block 9 moves to the initial position. At the same time, the long rod 10 will press the inclined section of the pressing groove 12, causing the slider 11 to move upward with the stop rod 14 to the initial position, so that the stop rod 14 no longer blocks the connector 6. At this time, the staff can manually remove the main body 5.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
