Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, in particular to a brake disc welding equipment. Background Art

[0002] A brake disc is a round plate that rotates as the car moves. The brake caliper clamps the disc, generating braking force. When you apply the brakes, it's the disc that slows or stops the car. Disc brakes offer superior 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) arranged in the circumferential direction of the inner ring. During production and processing, the inner ring (B) needs to be placed in the circumferential direction of the inner ring and welded. In the existing technology, when welding the brake disc, manual handheld welding heads are generally used for welding, which is inefficient and has unstable welding quality.

[0004] In view of this, a brake disc welding equipment is urgently needed. Summary of the Invention

The moving assembly is used to adjust the position of the welding head so that the welding head welds the connection between the outer ring and the inner ring on the welding station.

[0007] The welding station includes a welding platform and a first driving assembly. The welding platform is arranged on the frame. The first driving assembly is used to drive the welding platform to rotate.

[0008] The inner ring fixing mechanism includes an elastomer and a deformation component. The elastomer is arranged on the welding platform, and the inner ring is sleeved on the ring side of the elastomer. The elastomer is elastic, and the deformation component is used to deform the elastomer so that the ring side of the elastomer contacts the inner side of the inner ring.

[0009] The elastic body is annular, and the deformation component is used to support the elastic body from the inner side of the elastic body.

[0010] The deformation assembly includes a plug and a second driving member. The plug is arranged on the welding platform and is in the shape of a frustum. The plug is coaxially arranged with the elastomer. The second driving member is used to make the elastomer and the plug move relative to each other, so that the plug is inserted into the inner side of the elastomer or pulled out from the inner side of the elastomer.

[0011] The second driving member includes a pull plate, a pull rod and a cylinder. The pull plate is arranged on the top of the elastic body, the plug is arranged on the bottom of the elastic body, the plug is annular, the pull rod is passed through the plug, and the output end of the cylinder is connected to the pull rod.

[0012] The second driving member further includes an elastic member. A limiting plate is provided at the bottom of the pull rod, and the elastic member is provided at the bottom of the limiting plate.

[0013] The elastic member is a spring or a spring.

[0014] The inner ring fixing mechanism further includes a support ring, which is arranged on the welding platform and in the circumferential direction of the elastomer, and is used to support the inner bottom of the inner ring.

[0015] The outer ring fixing mechanism includes a plurality of electromagnets, and the plurality of electromagnets are arranged on the welding platform.

[0016] The welding station further comprises a hollow ring plate, which is embedded in the welding platform. An annular groove is provided on the top of the hollow ring plate, and the annular groove is located below the connection between the inner ring and the outer ring.

[0017] The moving component is a three-axis motion platform arranged on the frame, and the welding head is arranged on the three-axis motion platform.

[0018] The above structure of the present invention can achieve the following beneficial effects: When in use, the outer ring is fixed to the welding station by the outer ring fixing mechanism, and the inner ring fixing mechanism fixes the inner ring to the welding station so that the outer ring and the inner ring are coaxial. Then, the position of the welding head is adjusted by the moving component to weld the connection between the outer ring and the inner ring. In addition, multiple welding stations can be set, so that when one welding station is in the process of welding, the material can be loaded and unloaded at another welding station, thereby improving the welding efficiency. Since the position of the welding head is adjusted by the moving component synchronously, there is no need to manually hold the welding head, so the welding quality is kept stable. In order to avoid the solder adhering to the welding platform during welding, which causes the product and the welding platform to be welded together, making the welded product difficult to remove, the welding platform damaged or the product defective, an annular groove is set at the bottom of the weld, which is beneficial to improve the quality after welding and increase the yield rate.

[0021] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0022] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or equipment.

[0023] The following is combined with Figure 1-6 This application is described in further detail.

[0024] refer to Figure 1-Figure 4A brake disc welding device shown includes: a frame, a welding mechanism and a welding station 1 are provided on the frame, the welding station 1 is provided with one or more, and the welding station 1 is provided 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 assembly 5 . The moving assembly 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 on the welding station 1 .

[0025] Based on the above structure, when in use, the outer ring is fixed to the welding station 1 through the outer ring fixing mechanism 3, and the inner ring is fixed to the welding station 1 through the inner ring fixing mechanism 2, so that the outer ring and the inner ring are coaxial, and 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, and multiple welding stations 1 can be set, so that when one welding station 1 is in welding, another welding station 1 can be loaded and unloaded, thereby improving the welding efficiency. Since the position of the welding head 4 is adjusted by the synchronous change of the moving component 5, there is no need to manually hold the welding head, thereby maintaining the stability of the welding quality.

[0026] like Figure 2 As shown, the welding station 1 includes a welding platform 11 and a first drive assembly 12. The welding platform 11 is arranged on a frame. The first drive assembly 12 is used to drive the welding platform 11 to rotate. Since the weld between the outer ring and the inner ring is annular, when the welding head 4 is welding, the first drive assembly 12 drives the welding platform 11 to rotate, so that the welds are welded in sequence.

[0027] like Figure 3-Figure 5As shown, the inner ring fixing mechanism 2 includes an elastic body 21 and a deformation component. The elastic body 21 is arranged on the welding platform 11, and the inner ring is sleeved on the ring side of the elastic body 21. The elastic body 21 has elasticity. The deformation component is used to deform the elastic body 21 so that the ring side of the elastic body 21 contacts the inner side of the inner ring. The elastic body 21 is preferably annular, and the deformation component is used to support the elastic body 21 from the inner side of the elastic body 21. The deformation component specifically includes a head 22, a pull plate 23, a pull rod 24 and a cylinder 25. The head 22 is set on the welding platform 11, the plug 22 is in the shape of a cone, the plug 22 is coaxial with the elastic body 21 (the top of the plug 22 (the end with the smaller diameter) is inserted into the elastic body 21 from bottom to top), the pull plate 23 is set on the top of the elastic body 21, the plug 22 is set at the bottom of the elastic body 21, the plug 22 is annular, the pull rod 24 is inserted into the plug 22, and the output end of the cylinder 25 is connected to the pull rod 24. In this way, when in use, the inner ring is set on the ring side of the elastic body 21, and then through The cylinder 25 drives the pull rod 24 to move, causing the pull plate 23 to move toward one side of the elastic body 21, causing the elastic body 21 and the plug 22 to move relative to each other (the plug 22 goes deeper into the elastic body 21). Since the plug 22 is in the shape of a cone, the elastic body 21 is supported in the circumferential direction, so that the circumferential size of the elastic body 21 becomes larger, and the inner ring is supported from the inner side of the inner ring, thereby fixing the horizontal position of the inner ring. In addition, a limit plate 27 is provided at the bottom of the pull rod 24, and an elastic member 26 is provided at the bottom of the limit plate 27 (when When the pull rod 24 moves toward the side of the elastic body 21, the elastic member 26 is compressed). When welding is completed or the inner ring needs to be released, 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 resets the pull rod 24, and then the elastic body 21 and the plug 22 move relative to each other (the plug 22 moves to the side away from the elastic body 21). At this time, the elastic body 21 is deformed and reset, and the annular size of the elastic body 21 becomes smaller, so that the inner ring is in a free state.

[0028] Further optimization is, Figure 6 As shown, the elastic body 21 can be made of an elastic material in one piece, and 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 the outer sides of the movable blocks 211 are provided with limiting grooves 213, and the elastic ring 212 is clamped in the limiting grooves 213; in this way, when the head 22 moves toward the inner side of the plurality of movable blocks 211, it contacts 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), contacting the inner side of the inner ring, and limiting the inner ring; when the head 22 moves toward 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 head 22 is used to limit the position of the plurality of movable blocks 211).

[0029] As a further optimization, the elastic member 26 may be a spring or a spring sheet, and the elastic member 26 is disposed in the welding platform 11 .

[0030] like Figure 4 and Figure 5 As shown, since the inner side of the inner ring and the outer side of the inner ring are not in the same horizontal plane, in order to support the inner side of the inner ring and ensure that the inner ring and the outer ring are at a suitable welding angle, the inner ring fixing mechanism 2 also includes a support ring 28, which is arranged on the welding platform 11. The support ring 28 is arranged in the circumferential direction of the elastomer 21 and is used to support the inner bottom of the inner ring. When the inner ring is sleeved on the circumferential direction of the elastomer 21, the support ring 28 is supported on the inner bottom of the inner ring so that the inner ring and the outer ring are at a suitable docking angle. The support ring 28 can be replaced to support the inner side of the inner ring at different heights.

[0031] like Figure 4 As shown, the outer ring fixing mechanism 3 includes a plurality of electromagnets, and the plurality of electromagnets are arranged on the welding platform 11. Since the outer ring is in the shape of a flat plate, and after the inner ring is fixed, the relative position of the outer ring in the horizontal direction is fixed, it is only necessary to restrict the outer ring from moving during welding. Therefore, a plurality of electromagnets are arranged on the welding platform 11 (below the position where the outer ring is placed). During welding, the electromagnets are energized to fix the outer ring on the welding platform 11, thereby completing the fixation 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.

[0032] like Figure 4 and Figure 5 As shown, the welding station 1 also includes a hollow ring plate 13, which is embedded in the welding platform 11. An annular groove 14 is provided on the top of the hollow ring plate 13, and the annular groove 14 is located below the connection between the inner ring and the outer ring. In this way, it is avoided that the solder adheres to the welding platform 11 during welding, causing the product and the welding platform 11 to be welded together, resulting in the welded product being difficult to remove, the welding platform 11 being damaged or the product being defective. In this regard, the provision of the annular groove 14 is conducive to improving the quality after welding and improving the yield rate. Moreover, the hollow ring plates 13 with the annular groove 14 at different positions can be replaced according to the different weld positions of the welding products to adapt to the welding of products of different specifications.

[0033] like Figure 3 As shown, the moving component 5 is a three-axis motion platform arranged on the frame, and the welding head 4 is arranged 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.

[0034] In summary, when 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, so that the outer ring and the inner ring are coaxial, and 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, and multiple welding stations 1 can be set, so that when one welding station 1 is in welding, the material can be loaded and unloaded at another welding station 1, thereby improving the welding efficiency. Since the position of the welding head 4 is adjusted by the synchronous change of the moving component 5, there is no need to manually hold the welding head, so the welding quality is kept stable. In order to avoid the solder adhering to the welding platform 11 during welding, which causes the product and the welding platform 11 to be welded together, making the welded product difficult to remove, the welding platform 11 damaged or the product defective, an annular groove 14 is provided at the bottom of the weld, which is beneficial to improving the quality after welding and increasing the yield rate.

[0035] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations directly derived or imagined by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the scope of protection of the present invention.
