Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a brake disc welding station. Background Technology

[0002] A brake disc is simply a round plate that rotates when the car is moving. The brake caliper clamps onto the brake disc to generate braking force; when you press the brake pedal, it's the caliper that clamps onto the brake disc to slow down or stop the car. Brake discs offer better braking performance and are easier to maintain than drum brakes.

[0003] like Figure 1 The brake disc shown mainly consists of two parts: an inner ring (B) and an outer ring (A) located circumferentially on the inner ring. During production, the inner ring needs to be fitted onto the inner ring and welded. In the prior art, when welding the brake disc, the inner ring is generally fixed by a clamp. Fixing the inner ring with a clamp not only easily scratches the surface of the inner ring, but the clamp also extends to the end face of the clamp, which may interfere with the welding of the weld joint.

[0004] In view of this, there is an urgent need for a brake disc welding station. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A brake disc welding station includes: a welding station, wherein an inner ring fixing mechanism and an outer ring fixing mechanism are provided on the welding station, the outer ring fixing mechanism is used to fix the outer ring on the welding station, and the inner ring fixing mechanism is used to fix the inner ring on the welding station, so that the outer ring and the inner ring are coaxial;

[0008] The welding station includes a welding platform and a first drive assembly, the first drive assembly being used to drive the welding platform to rotate.

[0009] The inner ring fixing mechanism includes an elastic body and a deformation component. The elastic body is disposed on the welding platform, and the inner ring is sleeved on the ring side of the elastic body. The elastic body is elastic, and the deformation component is used to deform the elastic body so that the ring side of the elastic body abuts against the inner side of the inner ring.

[0010] The elastomer is ring-shaped, and the deformation component is used to support the elastomer from the inside.

[0011] The deformation assembly includes a mandrel and a second driving member. The mandrel is disposed on the welding platform and is frustoconical in shape. The mandrel is coaxially disposed with the elastic body. The second driving member is used to move the elastic body and the mandrel relative to each other, so that the mandrel is inserted into the inner side of the elastic body or pulled out from the inner side of the elastic body.

[0012] The second driving component includes a pull plate, a pull rod, and a cylinder. The pull plate is disposed on the top of the elastic body, the top head is disposed on the bottom of the elastic body, the top head is annular, the pull rod passes through the top head, and the output end of the cylinder is connected to the pull rod.

[0013] The second driving component also includes an elastic element, and a limiting plate is provided at the bottom of the pull rod, with the elastic element disposed at the bottom of the limiting plate.

[0014] The elastic element is a spring or a sheet spring.

[0015] The inner ring fixing mechanism further includes a support ring, which is disposed on the welding platform and in the circumferential direction of the elastic body, for supporting the inner bottom of the inner ring.

[0016] The outer ring fixing mechanism includes a plurality of electromagnets, which are disposed on the welding platform.

[0017] The elastic body includes an elastic element and a plurality of circumferentially distributed movable blocks, with the elastic ring sleeved around the circumferential sides of the movable blocks.

[0018] The welding station also includes a perforated ring plate, which is embedded in the welding platform. The top of the perforated ring plate is provided with an annular groove, which is located below the connection between the inner ring and the outer ring.

[0019] The above-described structure of this utility model can achieve the following beneficial effects:

[0020] The deformation component causes the elastomer to deform, allowing the elastomer to be supported from the inside of the inner ring, thus fixing the position of the inner ring. This not only prevents scratching the surface of the inner ring, but also prevents the elastomer from extending to the end face of the inner ring, thus avoiding interference with the welding of the weld joint.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0031] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0032] refer to Figures 1-4The brake disc welding equipment shown includes: a frame, on which a welding mechanism and several welding stations 1 are arranged. Each welding station 1 is equipped with an inner ring fixing mechanism 2 and an outer ring fixing mechanism 3. The welding mechanism includes a welding head 4 and a moving component 5. The moving component 5 is used to adjust the position of the welding head 4 so that the welding head 4 welds the connection between the outer ring and the inner ring at one of the welding stations 1. In use, the outer ring is fixed to the welding station 1 by the outer ring fixing mechanism 3, and the inner ring is fixed to the welding station 1 by the inner ring fixing mechanism 2, making the outer ring and the inner ring coaxial. Then, the position of the welding head 4 is adjusted by the moving component 5 to weld the connection between the outer ring and the inner ring. Multiple welding stations 1 are provided, so that while one welding station 1 is welding, another welding station 1 can be loaded and unloaded, improving welding efficiency. Because the position of the welding head 4 is adjusted synchronously by the moving component 5, there is no need for manual handling of the welding head, thus maintaining stable welding quality.

[0033] like Figure 3-4 As shown, welding station 1 includes welding platform 11 and first drive assembly 12. Welding platform 11 is mounted on the frame. First drive assembly 12 is used to drive welding platform 11 to rotate. Since the weld between outer ring and inner ring is annular, when welding head 4 is welding, first drive assembly 12 drives welding platform 11 to rotate, so that weld seams are welded sequentially.

[0034] like Figures 4-6As shown, the inner ring fixing mechanism 2 includes an elastic body 21 and a deformation component. The elastic body 21 is disposed on the welding platform 11, and the inner ring is sleeved on the ring side of the elastic body 21. The elastic body 21 is elastic, and the deformation component is used to deform the elastic body 21 so that the ring side of the elastic body 21 abuts against the inner side of the inner ring. By deforming the elastic body 21 through the deformation component, the elastic body 21 is supported from the inner side of the inner ring, thus fixing the position of the inner ring. This not only prevents scratching the surface of the inner ring, but also prevents the elastic body 21 from extending to the end face of the inner ring, thus avoiding interference with the welding of the weld joint. The elastic body 21 is preferably annular, and the deformation assembly is used to support the elastic body 21 from the inside. The deformation assembly specifically includes a top 22, a pull plate 23, a pull rod 24, and a cylinder 25. The top 22 is set on the welding platform 11 and is frustoconical in shape. The top 22 is coaxially arranged with the elastic body 21 (the top of the top 22 (the smaller diameter end) passes through the elastic body 21 from bottom to top). The pull plate 23 is set at the top of the elastic body 21, and the top 22 is set at the bottom of the elastic body 21. The top 22 is annular, and the pull rod 24 passes through the top 25. On the head 22, the output end of the cylinder 25 is connected to the pull rod 24. Thus, in use, the inner ring is fitted onto the ring side of the elastic body 21, and then the cylinder 25 drives the pull rod 24 to move, causing the pull plate 23 to move towards one side of the elastic body 21, causing the elastic body 21 to move relative to the top head 22 (the top head 22 delves deeper into the elastic body 21). Since the top head 22 is frustoconical, it supports the elastic body 21 circumferentially, increasing the circumferential dimension of the elastic body 21, thus supporting the inner ring from the inside and fixing the horizontal position of the inner ring. Furthermore, the bottom of the pull rod 24 is provided with… The limiting plate 27 has an elastic element 26 at its bottom (the elastic element 26 is compressed when the pull rod 24 moves toward the elastic body 21). When welding is completed or it is necessary to release the fixation of the inner ring, the cylinder 25 drives the pull rod 24 to move in the opposite direction, or the cylinder 25 releases the control of the pull rod 24. The elastic force of the elastic body 21 causes the pull rod 24 to reset, thereby causing the elastic body 21 to move relative to the top head 22 (the top head 22 moves away from the elastic body 21). At this time, the elastic body 21 is deformed and reset, and the circumferential dimension of the elastic body 21 becomes smaller, so that the inner ring is in a free state.

[0035] A further optimization is that the elastic element 26 can be a spring or a sheet, and the elastic element 26 is disposed within the welding platform 11.

[0036] like Figure 5 and Figure 6As shown, since the inner side and outer side of the inner ring are not on the same horizontal plane, in order to support the inner side of the inner ring and ensure that the inner ring and outer ring are at a suitable welding angle, the inner ring fixing mechanism 2 also includes a support ring 28. The support ring 28 is disposed on the welding platform 11 and is disposed in the circumferential direction of the elastic body 21. It is used to support the inner bottom of the inner ring. When the inner ring is fitted onto the circumferential direction of the elastic body 21, the support ring 28 supports the inner bottom of the inner ring, so that the inner ring and outer ring are at a suitable docking angle. The support ring 28 can be replaced to provide support for the inner side of the inner ring at different heights.

[0037] Further optimizations include, for example Figure 7 As shown, the elastic body 21 can be integrally made of elastic material. The elastic body 21 can also be composed of an elastic ring 212 and a plurality of movable blocks 211 distributed in a circle. The elastic ring 212 is sleeved on the ring side of the plurality of movable blocks 211. And each movable block 211 is provided with a limiting groove 213 on its outer side, and the elastic ring 212 is locked in the limiting groove 213. In this way, when the top head 22 moves to the inner side of the plurality of movable blocks 211, it abuts against the inner side of the plurality of movable blocks 211, causing the plurality of movable blocks 211 to move outward (stretching the elastic ring 212), abutting against the inner side of the inner ring, and limiting the inner ring. When the top head 22 moves to the outer side of the plurality of movable blocks 211, the plurality of movable blocks 211 are reset by the elastic force of the elastic ring 212 (when in the reset state, the top head 22 is used to limit the position of the plurality of movable blocks 211).

[0038] like Figure 5 As shown, the outer ring fixing mechanism 3 includes several electromagnets, which are arranged on the welding platform 11. Since the outer ring is a flat plate shape, and the relative position of the outer ring in the horizontal direction is fixed after the inner ring is fixed, it is only necessary to restrict the outer ring from moving during welding. Therefore, several electromagnets are arranged on the welding platform 11 (below the outer ring placement position). During welding, the electromagnets are energized to fix the outer ring on the welding platform 11, thus completing the fixing of the outer ring. Compared with fixing methods such as mechanical clamps, the outer ring fixing mechanism 3 in this embodiment is more convenient to use.

[0039] like Figure 5 and Figure 6As shown, welding station 1 also includes a perforated ring plate 13, which is embedded in the welding platform 11. The top of the perforated ring plate 13 is provided with an annular groove 14, which is located below the connection between the inner and outer rings. This prevents the solder from adhering to the welding platform 11 during welding, which would cause the product to be welded to the welding platform 11, making it difficult to remove the welded product, damaging the welding platform 11, or resulting in defective products. Therefore, the setting of the annular groove 14 helps to improve the quality of the weld and increase the yield rate. Furthermore, the perforated ring plate 13 at different positions of the annular groove 14 can be replaced according to the different weld seam positions of the welded products to adapt to the welding of products of different specifications.

[0040] like Figure 3 As shown, the moving component 5 is a three-axis motion platform set on the frame, and the welding head 4 is set on the three-axis motion platform. The welding head 4 is supported by the three-axis motion platform, making the welding head 4 more flexible and convenient for welding products on multiple welding stations 1.

[0041] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
