Description

Technical Field

[0001] This utility model relates to the field of wheel rim welding fixtures, specifically a welding device for ultra-wide wheel rims. Background Technology

[0002] During the manufacturing process of wheel rims, the plate blank is rolled into a cylindrical wheel rim base material. In order to ensure that the wheel rim base material can form a wheel rim with an integral structure, resistance welding is usually used to weld the wheel rim base material at the location of the weld seam.

[0003] Patent application number 202022012856.4 discloses a steel wheel rim strip butt welding clamping device. The device frame is located at the rim strip butt welding area at one end of the transfer slide, and the other end of the transfer slide is located between two transmission roller frames arranged at 90 degrees.

The middle of the two stabilizing roller pneumatic cylinders is equipped with an inner pressure roller pneumatic cylinder, and the piston end of the inner pressure roller pneumatic cylinder is equipped with an inner pressure roller. The bottom of the device frame is fixedly connected to the transfer slide.

[0004] The aforementioned steel wheel rim strip welding clamping device uses a compression spring to clamp and fix the welding end of the wheel hub. However, because the wheel hub material generates elastic stress when bending, the elasticity of the wheel hub material will squeeze the spring, resulting in loosening of the fixation and poor stability of the welding fixation of the wheel hub material. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an ultra-wide rim welding device to solve the technical problem that the elasticity of the wheel hub material will compress the spring and cause the fixing to loosen, resulting in poor stability of the welding and fixing of the wheel hub material.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultra-wide wheel rim welding device, comprising a base and a mounting frame fixed on the base in a cross-shaped structure, wherein a support plate is fixed to the top of the base, and a top plate is symmetrically fixed to the top of the mounting frame, and a first pressure plate and a second pressure plate are slidably arranged at both ends of the mounting frame, wherein the mounting frame is provided with a driving mechanism for driving the first pressure plate and the second pressure plate to move towards each other, and ultra-wide wheel hub raw material is fixed between the support plate and the top plate.

[0007] The present invention is further configured such that the side wall of the support plate is symmetrically provided with screw holes, and the bottom end of the side wall of the mounting bracket is provided with a bolt threaded into the screw hole.

[0008] The present invention is further configured such that both ends of the mounting bracket are rotatably provided with positioning rods, and the positioning rods abut against the outer wall of the ultra-wide wheel hub material.

[0009] The present invention is further configured such that both ends of the mounting bracket are provided with sliding grooves, and the driving mechanism includes a double-threaded screw rotatably disposed between the two sliding grooves and a knob disposed above the mounting bracket and fixed to the double-threaded screw.

[0010] The present invention is further configured such that both the first pressure plate and the second pressure plate are provided with protrusions that fit into the slide groove, and the two ends of the double threaded screw with opposite thread directions are respectively threaded into the first pressure plate and the second pressure plate.

[0011] The present invention is further configured such that the first pressure plate and the second pressure plate both abut against the inner wall of the ultra-wide wheel hub material, and the top end of the second pressure plate is provided with a groove with an arc-shaped structure.

[0012] The present invention is further configured such that the side of the base and the top plate facing each other are arc-shaped and abut against the outer wall of the ultra-wide wheel hub material, and a welding cavity is provided between the two top plates.

[0013] In summary, the present invention has the following advantages: By setting a support plate and a top plate on the base and mounting frame respectively, the base, positioning rod and top plate position the welding of the ultra-wide wheel hub material, and by rotating the double threaded screw through the knob, the first pressure plate and the second pressure plate squeeze and fix the inner wall of the ultra-wide wheel hub material, thereby improving the stability of the ultra-wide wheel hub material during welding.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] An ultra-wide rim butt welding device, such as Figure 1-4 As shown, the system includes a base 1 and a cross-shaped mounting bracket 6 fixed on the base 1. A support plate 10 is fixed to the top of the base 1, and a top plate 4 is symmetrically fixed to the top of the mounting bracket 6. A first pressure plate 13 and a second pressure plate 15 are slidably arranged at both ends of the mounting bracket 6. The mounting bracket 6 is equipped with a drive mechanism for moving the first pressure plate 13 and the second pressure plate 15 toward each other. An ultra-wide wheel hub material 3 is fixed between the support plate 10 and the top plate 4. The ultra-wide wheel hub material 3 is 15-17 inches in size. The distance between the support plate 10 and the top plate 4 matches the ultra-wide wheel hub material 3, so that the welding part of the ultra-wide wheel hub material 3 is located in the welding cavity between the two top plates 4. The base 1, the positioning rod 2, and the top plate 4 position the welding of the ultra-wide wheel hub material 3. The ultra-wide wheel hub material 3 is held by hand to keep it relatively stable. The knob 5 drives the double threaded screw 8 to rotate, so that the first pressure plate 13 and the second pressure plate 15 press and fix the inner wall of the ultra-wide wheel hub material 3.

[0021] The support plate 10 has symmetrically opened screw holes 11 on its side wall. The bottom of the side wall of the mounting bracket 6 is provided with a bolt threaded into the screw hole 11. Both ends of the mounting bracket 6 are rotatably provided with positioning rods 2. The positioning rods 2 abut against the outer wall of the ultra-wide wheel hub material 3. Both ends of the mounting bracket 6 are provided with sliding grooves 7. The driving mechanism includes a double threaded screw 8 rotatably set between the two sliding grooves 7 and a knob 5 set above the mounting bracket 6 and fixed to the double threaded screw 8. The base 1, positioning rods 2 and top plate 4 position the welding of the ultra-wide wheel hub material 3, and drive the double threaded screw 8 to rotate through the knob 5, so that the first pressure plate 13 and the second pressure plate 15 squeeze and fix the inner wall of the ultra-wide wheel hub material 3.

[0022] Furthermore, both the first pressure plate 13 and the second pressure plate 15 are provided with protrusions that fit into the slide groove 7. The two ends of the double threaded screw 8 with opposite thread directions are respectively threaded into the first pressure plate 13 and the second pressure plate 15. Both the first pressure plate 13 and the second pressure plate 15 abut against the inner wall of the ultra-wide wheel hub material 3. The top of the second pressure plate 15 is provided with an arc-shaped groove 16, which is used to store and discharge welding slag. The side of the base 1 facing the top plate 4 is arc-shaped and abuts against the outer wall of the ultra-wide wheel hub material 3. A welding cavity is provided between the two top plates 4. Since the ultra-wide wheel hub material 3 is in contact with the side wall of the mounting frame 6 during welding, it is blocked by the mounting frame 6 and the second pressure plate 15, so the welding slag produced by the welding of the ultra-wide wheel hub material 3 will not splash onto the surface of the double threaded screw 8.

[0023] The working principle of this utility model is as follows: When in use, the ultra-wide wheel hub material 3 is placed between the support plate 10 and the top plate 4, so that the welding part of the ultra-wide wheel hub material 3 is in the welding cavity between the two top plates 4. The base 1, the positioning rod 2 and the top plate 4 position the welding of the ultra-wide wheel hub material 3. When the ultra-wide wheel hub material 3 is held by hand to keep it relatively stable, the knob 5 is held to drive the double threaded screw 8 to rotate, so that the first pressure plate 13 and the second pressure plate 15 press and fix the inner wall of the ultra-wide wheel hub material 3. After fixing, the welding equipment (existing products, not described in detail) is used to weld the weld of the ultra-wide wheel hub material 3, which improves the stability of the ultra-wide wheel hub material 3 during welding.
