Description

Technical Field

[0001] The invention relates to the technical field of compressor bracket manufacturing, in particular to a positioning structure for a compressor bracket welding device. Background Art

[0002] In the patent application with application publication number CN206898636U, a welding tool for welding the liquid reservoir bracket of an air-conditioning compressor is disclosed, which includes a frame, a support platform, a longitudinal positioning device, a welding device and a main shell side hole detection device. The frame includes a horizontal support part a and a vertical support part b. The support platform is installed above the horizontal support part a and is parallel to the horizontal support part a. Two inclined plates extending toward the vertical support part b of the frame are provided on the support platform. The two inclined plates are inclined outward and symmetrically arranged. The two inclined plates have a symmetrical plane in a vertical state. One end of the longitudinal positioning device is fixedly connected to the vertical support part b of the frame. The main body of the longitudinal positioning device is a horizontally arranged cylindrical structure. The axis of the longitudinal positioning device is on the symmetrical plane of the two inclined plates. The welding The device includes an upper conductive block, a lower conductive block and a driving cylinder. The driving cylinder is fixedly mounted on the vertical support part b of the frame in a vertical state. The output end of the driving cylinder is set vertically downward. The upper conductive block is fixedly mounted on the output end of the driving cylinder. The lower conductive block is fixedly mounted on the main body of the longitudinal positioning device and is located directly below the upper conductive block. The longitudinal guiding device also includes a positioning column installed in a vertical state at the front end of the main body of the cylindrical structure. The axis of the positioning column is in the symmetrical plane of the two inclined plates. The main shell side hole detection device includes three detection components. The three detection components are fixedly mounted on the front end of the main body of the cylindrical structure and are staggered with each other. Each detection component is provided with a self-reflective light sensor extending along the radial direction of the main body of the cylindrical structure.

[0003] The advantages are: a welding tool for welding the liquid reservoir bracket of an air-conditioning compressor, which sleeves the main shell of the air-conditioning compressor on the longitudinal positioning device, and by adjusting the slider, the positioning column on the slider limits the main shell, and the three self-radiating light sensors correspond to the three measuring holes on the main shell for detection. When one of the self-reflective light sensors receives the signal emitted by itself, the driving cylinder will not drive the bracket to be welded with the main shell at high pressure; when the three self-reflective light sensors do not receive the signal emitted by themselves, the driving cylinder will drive the bracket to be welded with the main shell at high pressure. It has a simple structure, is easy to operate, adopts automatic mechanized detection, saves time and effort, and greatly improves production efficiency.

[0004] In the current compressor bracket welding equipment, the compressor bracket is generally placed at the welding position and then the bracket is welded. However, this welding method can only weld one bracket at a time, which is relatively inefficient. In addition, the bracket needs to be manually placed at the welding position for welding during the welding process, which not only wastes labor costs but also reduces production efficiency. At the same time, after welding is completed, the bracket needs to be manually removed, which may bring certain work-related injury risks and reduce production efficiency. Summary of the Invention

[0012] Preferably, the other end of the No. 2 connecting rod is movably connected to the outer wall of the inner cylinder through a rotating shaft, and the No. 2 connecting rods are evenly distributed on the outer wall of the inner cylinder.

[0016] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0017] (1) The present invention can greatly improve the welding efficiency of the bracket by cooperating with the bracket positioning mechanism, welding arm and linkage rack. In the traditional bracket welding process, the bracket needs to be transported, and the bracket after transportation needs to be manually placed at the welding site for welding. After welding, the bracket needs to be taken out. Such a process greatly reduces the welding efficiency of the bracket. The present invention drives the bracket on the bracket positioning mechanism to automatically fix, rotate and weld through the transmission of the conveyor belt itself, so that the bracket can be welded during transportation, which greatly improves the welding efficiency of the bracket and reduces a certain amount of labor cost. In addition, the bracket does not need to be manually fixed and can be adjusted automatically by the bracket positioning mechanism, which saves many steps and makes the bracket welding process integrated. While improving the bracket welding efficiency, it will not reduce the quality of the bracket welding.

[0018] (2) The present invention improves the efficiency and safety of the bracket welding process by coordinating the bracket positioning mechanism, the straight feeding mechanism and the conveyor belt. When the welded bracket moves to the bottom of the conveyor belt, it will slide to the inside of the collecting bin by gravity for collection. At the same time, the straight feeding mechanism allows the staff to only need to put the bracket in from the feeding port. This not only saves labor costs but also greatly reduces the risk of work-related injuries. In the traditional bracket welding process, the bracket needs to be placed manually at the welding site and the bracket needs to be taken out after the welding is completed. The present invention simplifies many steps and does not require manual intervention. The staff only needs to put the bracket in from the feeding port regularly and the present invention can automatically complete the subsequent welding work. This not only saves labor costs but also ensures the safety of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The straight feeding mechanism 3 includes a placement rack 301 installed on the top of the outer wall of the mounting rack 105, a feeding port 302 is installed on the top of the outer wall of the placement rack 301, a cylinder 303 is installed on the inner wall of the placement rack 301, a slide 304 is movably installed on the inner wall of the placement rack 301, a feeding trough 305 is installed on the bottom of the outer wall of the slide 304, a flap 306 is movably installed on the bottom of the outer wall of the feeding trough 305, and a bottom plate 307 is installed on both sides of the outer wall of the placement rack 301.

[0036] The linkage rack 107 is installed in equidistant sections, and the teeth of the linkage rack 107 are all meshed with the teeth of the linkage gear 201. Since the linkage rack 107 is installed in equidistant sections, the linkage gear 201 can rotate equidistantly every time it moves to the linkage rack 107.

[0037] The inner wall of the bottom bracket 203 is provided with a cavity, and the diameter of the force-bearing bracket 209 is adapted to the diameter of the cavity of the bottom bracket 203 . The weight of the bracket itself will drive the force-bearing bracket 209 to move downward in the cavity of the bottom bracket 203 .

[0038] The inner wall of the linkage block 207 is provided with a cavity, the diameter of the cavity of the linkage block 207 is adapted to the diameter of the mounting post 206 , and the linkage block 207 can slide on the outer wall of the mounting post 206 .

[0039] One end of the No. 1 connecting rod 210 is movably connected to the outer wall of the linkage block 207 through a rotating shaft, and the other end of the No. 1 connecting rod 210 is movably connected to the outer wall of the inner support plate 211 through a rotating shaft. The inner support plate 211 and the linkage block 207 form a transmission connection through the No. 1 connecting rod 210. When the linkage block 207 moves, the inner support plate 211 will be driven to move through the No. 1 connecting rod 210.

[0040] The other end of the No. 2 connecting rod 212 is movably connected to the outer wall of the inner column 204 through a rotating shaft. The No. 2 connecting rods 212 are evenly distributed on the outer wall of the inner column 204. When the inner support plate 211 moves, it will drive the No. 2 connecting rod 212 to rotate.

[0041] The inner wall of the placement rack 301 is provided with a slide groove, and the slide plate 304 is movably installed in the slide groove of the placement rack 301, and the slide plate 304 can slide in the slide groove of the placement rack 301.

[0042] The diameter of the inner wall of the material chute 305 matches the diameter of the material opening 302 , and the bottom of the material chute 305 is aligned with the top of the inner cylinder 204 . The bracket that slides down from the material chute 305 will just cover the outside of the inner cylinder 204 .

[0043] One end of the return spring 208 is connected to the outer wall of the inner plate 205 , and the other end of the return spring 208 is connected to the outer wall of the linkage block 207 . The return spring 208 can drive the linkage block 207 to reset.

[0044] The working principle and usage process of the present invention are as follows: first, the user needs to put the bracket of the compressor into the discharge port 302, and the bracket will slide from the inner wall of the discharge port 302 into the inner wall of the discharge chute 305. At this time, the flap 306 at the bottom of the discharge chute 305 will be supported by the bottom plate 307 so that the bracket stays in the inner wall of the discharge chute 305. Then the user starts the cylinder 303. After the cylinder 303 is started, it will drive the discharge chute 305 to move. When the discharge chute 305 moves, the slide 304 will slide in the slide groove on the inner wall of the placement rack 301. When the discharge chute 305 slides to a certain position, the flap 306 will open due to the lack of support from the bottom plate 307. After the flap 306 opens, the bracket on the inner wall of the discharge chute 305 will slide out, and the slid-out bracket will fall on the outer wall of the slide 304.

[0045] Secondly, when the bracket falls on the outside of the inner column 204, the bottom of the bracket will first touch the outer wall of the force-bearing leg 209, and the weight of the bracket itself will drive the force-bearing leg 209 to move downward in the cavity of the bottom bracket 203. When the force-bearing leg 209 moves, it will drive the linkage block 207 to slide on the outer wall of the mounting column 206. When the linkage block 207 slides, it will drive the inner support plate 211 to move through the No. 1 connecting rod 210. When the inner support plate 211 moves, it will show an open motion trajectory, and when the inner support plate 211 moves, it will drive the No. 2 connecting rod 212 to rotate. In this way, the movable distance of the inner support plate 211 can be adjusted according to the weight of the bracket, so that the inner support plate 211 supports the inner wall of the bracket to fix the bracket;

[0046] Finally, after the bracket is fixed, the user starts the conveyor belt 101. After the conveyor belt 101 is started, the linkage gear 201 is driven to move synchronously. After the linkage gear 201 moves to a certain distance, it meshes with the linkage rack 107 on the outer wall of the conveyor belt shell 102, driving the linkage gear 201 to rotate a certain angle, and the synchronous inner cylinder 204 will also rotate synchronously, so that the bracket outside the inner cylinder 204 will also rotate synchronously. Since the linkage rack 107 is installed in sections and at equal intervals, each time the linkage gear 201 moves to the linkage rack 107, it can rotate at equal intervals. When the linkage gear 201 moves to the linkage rack 107, After the gap between the racks 107 is formed, the user controls the conveyor belt 101 to stop, and then welds the bracket through the welding arm 106, and then starts the conveyor belt 101 to drive the linkage gear 201 to move. This cycle can be repeated so that the three parts of the bracket can be welded at equal distances. After the welding is completed, through the movement of the conveyor belt 101, when the linkage gear 201 moves to the bottom of the conveyor belt 101, due to the factor of gravity, the bracket will fall off from the outside of the inner column 204, and then fall to the collecting bin 104 for collection. After the bracket falls off, the reset spring 208 will drive the linkage block 207 to reset, and the work of the present invention is completed.

[0047] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
