Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a welding fixture for automotive parts. Background Technology

[0002] Automotive parts welding fixtures are tooling equipment specifically designed for the automotive manufacturing industry. Through precise positioning and fixing functions, they ensure that automotive parts maintain the correct position and shape during the welding process, thereby improving welding accuracy and efficiency, and guaranteeing the quality and consistency of automotive parts.

[0003] Existing automotive parts welding fixtures, when handling the welding of round tubular parts, can easily hinder welding operations and obstruct the view of the weld seam because the fixtures are fixed on the outside. Furthermore, when welding two round tubular parts together, two fixtures are required in conjunction with a centering instrument, which not only reduces welding efficiency but also increases production costs. Therefore, improvements are needed. Utility Model Content

[0004] One objective of this invention is to provide a welding fixture for automotive parts. This invention addresses the problems mentioned in the background regarding the existing automotive parts welding fixtures, which, when processing round tubular parts, easily obstruct welding operations and block the view of the weld seam because the fixtures are fixed on the outside. Furthermore, when aligning and welding two round tubular parts, two fixtures are required in conjunction with an alignment instrument, which not only reduces welding efficiency but also increases production costs.

[0005] A welding fixture for automotive parts according to an embodiment of the present utility model includes:

[0006] A first clamping mechanism is used to position a first cylindrical automotive part. The first clamping mechanism includes a rotating rod. A first sleeve is fixedly provided at one end of the outer side of the rotating rod. A first support ring is rotatably provided at the tail end of the first sleeve. A first moving ring is movably provided at the front end of the first sleeve through a first external thread. A first rotating seat is fixedly provided on the outer side of the first support ring and the first moving ring in a circular shape. A first scissor positioning component is provided between the two first rotating seats.

[0007] The second clamping mechanism is used to position the second cylindrical automotive part. The second clamping mechanism includes a second sleeve and a second support ring. The second support ring is movably disposed on the outside of the rotating rod and near the tail end of the second sleeve. The front end of the second sleeve is movably disposed with a second moving ring through a second external thread. The outer sides of the second support ring and the second moving ring are both fixedly disposed with second rotating seats in a circular shape. A second scissor positioning component is provided between the two second rotating seats.

[0008] Preferably, a nut is rotatably provided at the tail end of the first sleeve.

[0009] Preferably, the first scissor positioning component includes a first connecting rod. There are two first connecting rods, both located inside the first rotating seat. One end of the first connecting rod is provided with a first support plate. The first rotating seat, the first connecting rod, and the first support plate are all rotatably connected via a first rotating shaft.

[0010] Preferably, a first abutment is fixedly provided at one end of the first support plate, and the surface of the first abutment is provided with an anti-slip pad.

[0011] Preferably, a first knob is fixedly provided at the front end of the rotating rod.

[0012] Preferably, a second knob is fixedly provided at the front end of the second sleeve.

[0013] Preferably, the second scissor positioning assembly includes a second connecting rod. There are two second connecting rods, both located inside the second rotating seat. One end of the second connecting rod is provided with a second support plate. The second rotating seat, the second connecting rod, and the second support plate are all rotatably connected via a second rotating shaft.

[0014] Preferably, a second abutment is fixedly provided at one end of the second support plate, the surface of the second abutment is provided with an anti-slip pad, and a linkage frame is installed between the second support ring and the first moving ring.

[0015] The beneficial effects of this utility model are:

[0016] This utility model, through the design of a welding fixture for automotive parts, effectively avoids the problem of fixtures being fixed on the outside, which can easily hinder welding operations and obstruct the view of the weld. When welding round tubular automotive parts, the welding fixture is placed inside the round tubular part. By rotating the first knob, the first sleeve rotates under the connection of the rotating rod. The first moving ring is movably connected to the first sleeve through the first external thread. This allows the first connecting rod in the first scissor positioning assembly to perform a scissor-like outward expansion movement when the first moving ring approaches the first support ring. This allows the first support plate and the first abutment plate to support the inner wall of the round tubular part. Furthermore, the first abutment plate can increase the contact area to increase the stability of the round tubular part during welding. Therefore, this device can be positioned inside the round tubular part for clamping and positioning, avoiding problems such as obstruction or impact on welding efficiency.

[0017] This invention, through the provision of a first clamping mechanism and a second clamping mechanism, allows for the centering and welding of two cylindrical fittings. By rotating the first knob in the first clamping mechanism, one of the cylindrical fittings can be clamped and positioned by the first support plate and the first abutment. Then, by rotating the second knob in the second clamping mechanism, the second support plate and the second abutment also expand. Since a linkage frame connects the first moving ring and the second support ring, and the second support ring is movably connected to the outside of the rotating rod, the movement of the first moving ring simultaneously causes the second support ring to slide downwards and reach a limit position. Finally, rotating the second knob allows the second cylindrical fitting to be centered and positioned. Therefore, using the first clamping mechanism in conjunction with the second clamping mechanism effectively improves the welding efficiency between the two cylindrical fittings, eliminating the need for additional cost associated with centering instruments.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figure 1-4 A welding fixture for automotive parts, comprising:

[0026] A first clamping mechanism 1 is used to position a first cylindrical automotive part. The first clamping mechanism 1 includes a rotating rod 101. A first sleeve 102 is fixedly mounted on one end of the outer side of the rotating rod 101. A first support ring 103 is rotatably mounted on the tail end of the first sleeve 102. A first moving ring 105 is movably mounted on the front end of the first sleeve 102 via a first external thread 104. Both the first support ring 103 and the first moving ring 105 have first rotating seats 106 fixedly mounted on their outer sides in a circular shape. A first scissor-type positioning assembly is provided between the two first rotating seats 106. The first scissor-type positioning assembly includes a first connecting rod 107. There are two 7, both located inside the first rotating seat 106. One end of the first connecting rod 107 is provided with a first support plate 108. The first rotating seat 106, the first connecting rod 107 and the first support plate 108 are all rotatably connected through the first rotating shaft 109. By rotating the first knob, the first sleeve rotates under the connection of the rotating rod. The first moving ring is movably connected to the first sleeve through the first external thread. Thus, when the first moving ring approaches the first support ring, the first connecting rod in the first scissor positioning assembly can move outward in a scissor-like manner. Thus, the first support plate and the first abutment plate can be used to support the inner wall of the round tubular fitting.

[0027] The second clamping mechanism 2 is used to position the second cylindrical automotive part. The second clamping mechanism 2 includes a second sleeve 201 and a second support ring 203. The second support ring 203 is movably disposed on the outside of the rotating rod 101 and near the tail end of the second sleeve 201. A second moving ring 204 is movably disposed on the front end of the second sleeve 201 via a second external thread 202. A second rotating seat 205 is fixedly disposed on the outer side of both the second support ring 203 and the moving ring 204 in a circular shape. A second scissor-type positioning assembly is provided between the two second rotating seats 205. The second scissor-type positioning assembly includes two second connecting rods 206. All are located inside the second rotating seat 205. One end of the second connecting rod 206 is provided with a second support plate 208. The second rotating seat 205, the second connecting rod 206 and the second support plate 208 are all rotatably connected through the second rotating shaft 209. By rotating the second knob in the second clamping mechanism, the second support plate and the second abutment also make an expansion movement. Since there is a linkage frame connecting the first moving ring and the second support ring, and the second support ring is movably connected to the outside of the rotating rod, the movement of the first moving ring simultaneously drives the second support ring to slide downward and then limit it. Then, by rotating the second knob, the second round tube fitting can be centered and positioned.

[0028] Example 1: A nut 111 is rotatably provided at the tail end of the first sleeve 102, and a first abutment 110 is fixedly provided at one end of the first support plate 108. The first abutment can increase the contact area to increase the stability of the round tubular fitting during welding. The surface of the first abutment 110 is provided with an anti-slip pad to improve the stability of the round tubular fitting during clamping and positioning. A first knob 112 is fixedly provided at the front end of the rotating rod 101.

[0029] Example 2: A second knob 207 is fixedly provided at the front end of the second sleeve 201, and a second abutment 210 is fixedly provided at one end of the second support plate 208. The second abutment can increase the contact area to increase the stability of the round tubular fitting during welding. The surface of the second abutment 210 is provided with an anti-slip pad to improve the stability of the round tubular fitting during clamping and positioning. A linkage frame 211 is installed between the second support ring 203 and the first moving ring 105 to improve the centering welding efficiency.

[0030] Working principle: Two cylindrical automotive parts are positioned by the first clamping mechanism 1 and the second clamping mechanism 2 respectively. In the first clamping mechanism 1, the first sleeve 102 fixed at the end of the rotating rod 101 is connected to the first moving ring 105 through the first external thread 104. The first support ring 103 and the first moving ring 105 are both fixed with the first rotating seat 106 on the outside. The first scissor positioning assembly is provided inside. By rotating the first knob 112, the first sleeve 102 rotates under the drive of the rotating rod 101, and the first moving ring 105 moves along the first external thread 104, so that the first connecting rod 107 in the first scissor positioning assembly expands outward. The first support plate 108 and the first abutment plate 110 support the inner wall of the cylindrical part. In the second clamping mechanism 2, the front end of the second sleeve 201 is connected to the first moving ring 105 through the second external thread 202. Two moving rings 204 are connected. A second rotating seat 205 is fixed to the outside of both the second supporting ring 203 and the second moving ring 204. A second scissor positioning component is provided inside. The linkage frame 211 connects the first moving ring 105 and the second supporting ring 203, so that the movement of the first moving ring 105 drives the second supporting ring 203 to slide downward and limit its position. The nut 111 and the first abutment 110 increase the stability during welding. The anti-slip pad improves the stability during clamping and positioning. The second knob 207 is used to center and position the second round tubular fitting. The second abutment 210 and the anti-slip pad also improve stability. The linkage frame 211 improves the centering welding efficiency. In summary, this fixture achieves precise centering and stable welding of round tubular fittings through rotation and scissor expansion actions, thereby improving welding quality and production efficiency.
