Technical Field

[0001] This utility model relates to the field of wheel web welding technology, specifically a new type of welding fixture for the pentagonal web of a front wheel. Background Technology

[0002] A pentagonal web refers to a web with a pentagonal cross-section or five sets of symmetrical structures. It is commonly found in special wheels or irregularly shaped metal components. The pentagonal web welding fixture is a welding auxiliary device for webs, used for precise positioning and uniform clamping. Five positioning blocks are evenly distributed along the circumference, with each positioning block corresponding to one side of the pentagonal web for positioning.

[0003] In the existing technology, the two sides of the connecting plates around the pentagonal web plates of different sizes and types are not completely parallel and have a certain degree of inclination. This means that different positions may require different clamping angles to adapt to the slope, and different welding fixtures need to be changed frequently. In addition, the positioning blocks of the pentagonal web plate welding fixture are mostly fixed and adjusted with bolts, which makes the operation steps cumbersome. Therefore, a new type of front wheel pentagonal web plate welding fixture is needed to meet people's needs. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of welding fixture for the front wheel pentagonal web plate, so as to solve the problem that the positioning block of the pentagonal web plate welding fixture mentioned in the background art is mostly fixed and adjusted by bolts, which is cumbersome, and the welding fixture needs to be frequently changed when using pentagonal web plates of different sizes and types.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel welding fixture for the pentagonal web of a front wheel, comprising a support base; a central support column is installed on the support base, several adjusting slides are slidably installed on the support base, a material placement seat is installed on the adjusting slide, a positioning structure is connected to the material placement seat, a worm gear is rotatably installed inside the support base, and a linkage adjustment structure is connected to the worm gear.

[0006] Preferably, the positioning structure includes a bidirectional lead screw, which is rotatably installed inside the material placement seat. Two threaded slides are threaded onto the bidirectional lead screw, and an adjusting seat is rotatably installed on each of the two threaded slides. A clamping plate is installed between the two adjusting seats.

[0007] Preferably, rubber pads are installed on the sides of the two clamping plates that are close to each other.

[0008] Preferably, the material placement seat has a horizontal groove inside, and the threaded slide is slidably installed in the horizontal groove.

[0009] Preferably, a fixing bolt is movably installed inside the adjusting seat, with one end of the fixing bolt passing through the adjusting seat and threadedly installed inside the threaded slide.

[0010] Preferably, the linkage adjustment structure includes several arc-shaped linkage grooves, a linkage shaft is movably installed inside the arc-shaped linkage grooves, a T-shaped slide is installed at one end of the linkage shaft, the T-shaped slide is installed below the adjustment slide, a motor is installed on one side of the support base, a worm is installed at the output end of the motor, the worm is rotatably installed inside the support base, and the worm meshes with a worm wheel.

[0011] Preferably, the support base has several guide holes inside, and the T-shaped slide block is slidably installed in the guide holes.

[0012] Preferably, limit rings are installed on both sides of the worm gear, and both limit rings are rotatably installed inside the support base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) When using this utility model, the pentagonal web plate can be sleeved on the central support column, and the connecting plates around it can be placed on the corresponding material seats for support. By rotating the bidirectional screw, the clamping plates on both sides can be controlled to approach the connecting plates for positioning. The angle of the clamping plates can be adjusted by loosening the fixing bolts, which is convenient to adjust according to the inclination of the connecting plates on the web plate, so as to be suitable for pentagonal web plates of various sizes. The clamping plates can maintain the current position and angle, and can be repeatedly positioned and used when the pentagonal web plate is replaced for welding.

[0015] 2) Before use, the position of the adjusting slide can be adjusted according to the size of the pentagonal web. When the motor is turned on, the positions of the surrounding adjusting slide and the material placement seat can be adjusted at the same time, adjusting their spacing and the support position of the pentagonal web. This allows the support center of gravity of the material placement seat to be adjusted according to the size of the pentagonal web. The adjustment steps are simple and quick, and there is no need to repeatedly disassemble and reassemble the bolts. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a novel welding fixture for a front wheel pentagonal web plate, including a support base 100; a central support column 200 is installed on the support base 100, and several adjusting slides 201 are slidably installed on the support base 100. A material placement seat 202 is installed on the adjusting slides 201, and a positioning structure is connected to the material placement seat 202. The positioning structure is used to limit the position of the connecting plates around the web plate and to position the pentagonal web plate. A worm gear 300 is rotatably installed inside the support base 100, and a linkage adjustment structure is connected to the worm gear 300. The linkage adjustment structure is used to simultaneously adjust the support position of the surrounding positioning structures.

[0024] Furthermore, the positioning structure includes a bidirectional lead screw 203, which is rotatably installed inside the material placement seat 202. Two threaded slides 204 are threadedly fitted on the bidirectional lead screw 203, and an adjusting seat 205 is rotatably installed on each of the two threaded slides 204. A clamping plate 206 is installed between the two adjusting seats 205. Rotating the bidirectional lead screw 203 allows it to rotate inside the material placement seat 202. When the bidirectional lead screw 203 rotates, it can drive the two threaded slides 204 to slide closer or further away, thereby driving the adjusting seats 205 and the clamping plate 206 to move, so that the clamping plates 206 on both sides approach and stick to the connecting plate on the side of the web.

[0025] Furthermore, rubber pads are installed on the sides of the two clamping plates 206 that are close to each other. The installation of rubber pads can prevent the clamping plates 206 from damaging the surface of the pentagonal web plate.

[0026] Furthermore, the material holder 202 has a horizontal slide groove 207 inside, and the threaded slide 204 is slidably installed in the horizontal slide groove 207. When the threaded slide 204 moves, it will slide in the horizontal slide groove 207. The setting of the horizontal slide groove 207 can restrict the threaded slide 204 to move only in the horizontal direction.

[0027] Furthermore, a fixing bolt 208 is movably installed inside the adjusting seat 205. One end of the fixing bolt 208 passes through the adjusting seat 205 and is threaded inside the threaded slide 204. By rotating the fixing bolt 208 and unscrewing it from inside the threaded slide 204, the angle restriction on the adjusting seat 205 can be released. At this time, the clamp 206 can be flipped to adjust its angle.

[0028] Example 2: As Figure 1-3 To facilitate adjustment of the support center of gravity of the material placement seat 202 according to the size of the pentagonal web plate, a linkage adjustment structure is arranged. The linkage adjustment structure includes several arc-shaped linkage grooves 301. A linkage shaft 302 is movably installed inside the arc-shaped linkage grooves 301. A T-shaped slide 303 is installed at one end of the linkage shaft 302. The T-shaped slide 303 is installed below the adjustment slide 201. A motor 304 is installed on one side of the support seat 100. A worm gear 305 is installed at the output end of the motor 304. The worm gear 305 is rotatably installed inside the support seat 100. The worm gear 305 meshes with the worm wheel 300. Turning on the motor 304 can drive the worm gear 305 to rotate. When the worm gear 305 rotates, it can drive the worm wheel 300 to rotate, so that the worm wheel 300 can drive several arc-shaped linkage grooves 301 to simultaneously squeeze the corresponding linkage shafts 302, so that the linkage shafts 302 drive the surrounding adjustment slides 201 to move towards or away from the central support column 200.

[0029] Furthermore, the support base 100 has several guide sliding holes 306 inside. The T-shaped slide 303 is slidably installed in the guide sliding holes 306. When the T-shaped slide 303 moves, it will slide in the guide sliding holes 306. The direction of movement of the adjustment slide 201 can be restricted by the setting of the guide sliding holes 306.

[0030] Furthermore, limit rings 307 are installed on both sides of the worm gear 300. Both limit rings 307 are rotatably installed inside the support base 100. The rotating worm gear 300 can drive the limit rings 307 on both sides to rotate inside the support base 100. The setting of the limit rings 307 on both sides can limit the rotation position of the worm gear 300 and prevent the worm gear 300 from shifting position.

[0031] The working principle is as follows: During use, the center position of the front wheel's pentagonal web can be fitted onto the central support column 200. Its five connecting plates are respectively placed on the corresponding material placement seats 202. Rotating the bidirectional lead screw 203 allows it to rotate inside the material placement seat 202. The two ends of the bidirectional lead screw 203 are provided with threads facing opposite directions, and these threads are respectively adapted to two threaded slide blocks 204. Thus, when the bidirectional lead screw 203 rotates, it can drive the two threaded slide blocks 204 to slide closer or further apart within the horizontal sliding groove 207. Simultaneously, the movement of the threaded slide blocks 204 can drive the adjusting seat 205 and clamping plate 206 to move via the fixing bolt 208, causing the clamping plates 206 on both sides to move closer and adhere to the connecting plates on the sides of the web, forming a... Figure 1 The state facilitates the positioning of the pentagonal web for welding. By rotating the fixing bolt 208 and unscrewing it from inside the threaded slide 204, the angle restriction on the adjusting seat 205 can be released. At this time, the clamping plate 206 can be flipped to drive the adjusting seat 205 to rotate, so as to adjust the angle of the clamping plate 206 to adapt to the change in inclination of the connecting plate on the web. After adjustment, the fixing bolt 208 can be screwed back into the threaded slide 204 and the adjusting seat 205 can be pressed to re-restrict the angle of the clamping plate 206.

[0032] By turning on the motor 304, the worm 305 can be driven to rotate. When the worm 305 rotates, it can drive the worm wheel 300 to rotate through meshing with the worm wheel 300. The continuously rotating worm wheel 300 will drive several arc-shaped linkage grooves 301 to simultaneously squeeze the corresponding linkage shaft 302, so that the linkage shaft 302 drives the corresponding T-shaped slide block 303 to slide in the guide slide hole 306. In this way, the surrounding adjustment slide blocks 201 can be controlled to move towards or away from the central support column 200.
