Description

Technical Field

[0001] This utility model relates to a welding device for automotive parts. Background Technology

[0002] When welding automotive parts (such as body sheet metal parts and chassis structural parts), it is often necessary to align two parts at non-standard angles. Traditional welding equipment mostly uses fixed clamps or simple rotating mechanisms, which cannot achieve continuous and precise angle adjustment. This results in repeated trial assembly and measurement before welding, which is inefficient. Furthermore, it requires disassembling the clamps, repositioning, and tightening the bolts, with each adjustment taking 5-10 minutes. It also relies on the operator's experience, resulting in long welding cycles (low daily output per unit) and high labor costs.

[0003] Therefore, a welding device for automotive parts is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the existing defects and provide an automotive parts welding device that can effectively verify the reliability of diaphragm pumps.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding device for automotive parts, comprising: The base frame structure consists of a base plate and guide columns fixed to its top surface. A lifting cylinder is also fixed to the top surface of the base plate. Clamping mechanism: includes clamping plates and clamping bars, which are locked together by bolts to clamp the parts; Connection mechanism: includes middle plate, column, hinge seat, support rod, guide rail, slider, first support, second support, screw, extrusion plate and plastic sleeve; The intermediate plate is located between the clamping plate and the bottom plate, and can slide along the guide column. The output shaft of the lifting cylinder is fixedly connected to the intermediate plate. The clamping plate is rotatably connected to the intermediate plate via a hinge seat; The two ends of the support rod are rotatably connected to the slider and the first stand through the convex shaft, respectively, and the slider is slidably connected to the guide rail fixed to the bottom surface of the clamp plate; The screw is threadedly connected to the second support. Rotating the screw can push the extrusion plate to squeeze the plastic sleeve, eliminating the gap between the plastic sleeve and the support rod cam to lock the support rod angle.

[0006] Preferably, the base frame structure has four guide columns, which are vertically fixed to the top surface of the base plate and are used to guide the sliding of the intermediate plate.

[0007] Preferably, the clamping plate and clamping bar of the clamping mechanism have anti-slip textures on their opposing surfaces.

[0008] Preferably, the middle plate of the connecting mechanism is a rectangular plate structure, and a column is integrally fixed on its top surface. The column is used to support the clamping mechanism in a horizontal state.

[0009] Preferably, the guide rail is a linear slide rail, fixed to the bottom surface of the clamping plate.

[0010] Preferably, the plastic sleeve is made of polyurethane and has a circular structure design.

[0011] Preferably, the side of the extrusion plate is provided with a protrusion, which can be inserted into the first stand.

[0012] Preferably, the hinge seat is a ball joint hinge, which allows the clamping plate to adjust its angle to compensate for assembly errors of the parts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In this automotive parts welding device, the two ends of the support rod are rotatably connected to the slider and the first upright via convex shafts. The slider slides along the guide rail on the bottom surface of the clamping plate, forming a linkage mechanism.

Furthermore, the clamping plate is connected to the intermediate plate via a ball-head hinge seat, allowing the clamping plate to rotate freely, compensating for part assembly errors, and reducing manual adjustment time before welding.

[0016] 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.

[0017] like Figure 1-4 As shown, an automotive parts welding device includes: a base frame structure 1, which is integrally formed by a base plate 11 and a guide column 12 fixed to its top surface, and a lifting cylinder 13 is also fixed to the top surface of the base plate 11.

[0018] Clamping mechanism 2: includes clamping plate 21 and clamping bar 22, which are locked together by bolts 23 to clamp the parts; the clamping plate 21 and clamping bar 22 of clamping mechanism 2 are provided with anti-slip texture on the opposite surfaces to increase the friction coefficient and prevent the parts from sliding or falling off during clamping, especially suitable for smooth aluminum alloy or galvanized steel plate parts.

[0019] Connecting mechanism 3 includes a middle plate 35, a column 351, a hinge seat 34, a support rod 31, a guide rail 32, a slider 33, a first seat 36, a second seat 38, a screw 39, an extrusion plate 310, and a plastic sleeve 37.

[0020] The intermediate plate 35 is located between the clamping plate 21 and the base plate 11, and can slide along the guide post 12. The output shaft of the lifting cylinder 13 is fixedly connected to the intermediate plate 35. The intermediate plate 35 of the connecting mechanism 3 is a rectangular plate structure, and a column 351 is integrally fixed on its top surface. The column 351 is used to support the clamping mechanism 2 in a horizontal state. When the intermediate plate 35 supports the clamping mechanism 2, the force is evenly distributed, reducing the risk of local deformation. It is especially suitable for welding large-sized parts.

[0021] The clamping plate 21 is rotatably connected to the intermediate plate 35 via the hinge seat 34; the hinge seat 34 is a ball joint hinge, which allows the clamping plate 21 to adjust its angle to compensate for assembly errors of the parts.

[0022] The two ends of the support rod 31 are rotatably connected to the slider 33 and the first stand 36 via convex shafts, and the slider 33 is slidably connected to the guide rail 32 fixed to the bottom surface of the clamping plate 21.

[0023] The screw 39 is threadedly connected to the second support 38. Rotating the screw 39 can push the extrusion plate 310 to extrude the plastic sleeve 37, eliminating the gap between the plastic sleeve 37 and the convex shaft of the support rod 31 to lock the angle of the support rod 31.

[0024] Specifically, the base frame structure 1 has four guide posts 12, which are vertically fixed to the top surface of the base plate 11 to guide the sliding of the intermediate plate 35, forming a rigid guide frame. This ensures that the intermediate plate 35 slides along the guide posts 12 without offset, reduces positioning errors, and avoids part misalignment caused by device vibration during the welding process.

[0025] Specifically, the guide rail 32 is a linear slide rail, fixed to the bottom surface of the clamping plate 21, the plastic sleeve 37 is made of polyurethane and has a circular structure design, and the side of the extrusion plate 310 has a protrusion that can be inserted into the first stand 36.

[0026] This invention relates to an automotive parts welding device, applied to the positioning requirements of parts welding. A base plate 11 is integrally and fixedly connected to a guide post 12 to form a base frame structure 1. A lifting cylinder 13 is also fixed to the top surface of the base plate 11. A clamping mechanism 2 above the base frame structure 1 is connected to the base frame structure 1 via a connecting mechanism 3. The clamping plate 21 and clamping bar 22 of the clamping mechanism 2 are locked together using bolts 23. Therefore, after placing the part in the gap between the clamping bar 22 and the clamping plate 21, tightening the bolts 23 will fix the part in place. The clamping plate 21 is used for welding. The clamping plate 21 can be adjusted not only by the lifting cylinder 13, but also by the connecting mechanism 3, so that the two parts can be aligned at different angles for welding. The connecting mechanism 3 is based on an intermediate plate 35 and a column 351 integrally fixed to the top surface of the intermediate plate 35. The intermediate plate 35 is located between the clamping plate 21 and the base plate 11. The intermediate plate 35 can slide up and down along the guide column 12, and the output shaft of the lifting cylinder 13 is fixedly connected to the intermediate plate 35. The clamping plate 21 utilizes a hinge... The chain seat 34 is rotatably connected to the intermediate plate 35, while the two ends of the support rod 31 are rotatably connected to the slider 33 and the first upright seat 36 fixed on the top surface of the intermediate plate 35 via convex shafts. The slider 33 is also slidably connected to the guide rail 32 fixed on the bottom surface of the clamping plate 21. Therefore, after adjusting the angle of the support rod 31, the slider 33 slides along the guide rail 32, which can support the clamping plate 21, causing the clamping plate 21 to rotate along the hinge seat 34 to adjust its angle. At the same time, after the angle of the support rod 31 is adjusted, it rotates and is fixed on the top surface of the intermediate plate 35. The screw 39, which is threaded to the second support 38, compresses the extrusion plate 310 and slides it toward the center of the first support 36. This causes the protrusion on the side of the extrusion plate 310 to compress the plastic sleeve 37 inside the first support 36. The convex shaft of the support rod 31 is located inside the plastic sleeve 37. After the plastic sleeve 37 is compressed, the gap between it and the convex shaft at the end of the support rod 31 is eliminated, so that it fits tightly against the convex shaft at the end of the support rod 31. Combined with the extrusion force provided by the threaded engagement of the screw 39, the rotation of the support rod 31 is restricted, and the state of the support rod 31 is locked.

[0027] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
