Description

Technical Field

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

[0002] In the patent application with the publication number CN206898636U, a welding tool for welding an air-conditioning compressor liquid receiver bracket is disclosed, which includes a frame, a support table, a longitudinal positioning device, a welding device, and a main housing side hole detection device. The frame includes a horizontal support part a and a vertical support part b. The support table is installed above the horizontal support part a and is parallel to the horizontal support part a. Two inclined plates extending towards the vertical support part b of the frame are provided on the support table. The two inclined plates are both inclined outwards and symmetrically arranged. The two inclined plates have a vertical symmetry plane. 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 located in the symmetry plane of the two inclined plates. The welding device includes an upper conductive block, a lower conductive block, and a driving cylinder. The driving cylinder is fixedly installed in a vertical state on the vertical support part b of the frame. The output end of the driving cylinder is arranged vertically downwards. The upper conductive block is fixedly installed at the output end of the driving cylinder. The lower conductive block is fixedly installed on the main body of the longitudinal positioning device and is located directly below the upper conductive block. The longitudinal guiding device further includes a positioning column in a vertical state installed at the front end of the cylindrical main body. The axis of the positioning column is located in the symmetry plane of the two inclined plates. The main housing side hole detection device includes three detection components. The three detection components are fixedly installed at the front end of the cylindrical main body and are arranged staggeredly. Each detection component is provided with a self-reflective light sensor extending along the radial direction of the cylindrical main body.

[0003] Advantages: For a welding tool for welding an air-conditioning compressor liquid receiver bracket, the main housing of the air-conditioning compressor is sleeved on the longitudinal positioning device. By adjusting the slider, the positioning column on the slider limits the main housing. The three self-radiating light sensors respectively detect three measuring holes on the main housing. When one of the self-reflective light sensors receives the signal emitted by itself, the driving cylinder will not drive to perform high-pressure welding of the bracket and the main housing; when none of the three self-reflective light sensors receives the signal emitted by itself, the driving cylinder will drive to perform high-pressure welding of the bracket and the main housing. Its structure is simple, the operation is convenient, and it adopts automatic mechanized detection, saving time and effort, and greatly improving the production efficiency.

[0004] In current compressor bracket welding equipment, generally the compressor bracket is placed at the welding position and then welded. However, this welding method can only weld one bracket at a time, with relatively low efficiency. Also, during the welding process, it is necessary for workers to manually place the bracket at the welding position for welding. This not only wastes labor costs but also reduces production efficiency. At the same time, after welding, it is also necessary for workers to remove the bracket manually, which may pose certain work injury risks and reduce the output efficiency. Summary of the Invention

[0005] The problems to be solved by the present invention are: the insufficient efficiency of compressor bracket welding, and the safety hazards and low efficiency of manually placing and removing the bracket.

[0006] To solve the above technical problems, the technical solution of the present invention is: a positioning structure for a compressor bracket welding device, including a body structure.

The bracket positioning mechanism includes a linkage gear movably connected to the outer wall of the conveyor belt through a rotating shaft. A chassis is installed on the outer wall of the linkage gear. A bottom bracket is installed on the outer wall of the chassis. One end of the bottom bracket is connected to an inner cylinder body. An inner plate is provided on the inner wall of the inner cylinder body. A mounting post is installed on the outer wall of the inner plate. A linkage block is movably installed on the outer wall of the mounting post. A return spring is connected to the top of the outer wall of the linkage block. Force-bearing footrests are provided on the outer walls of the linkage blocks. One ends of the linkage blocks are movably connected to a first connecting rod through a rotating shaft. One end of the first connecting rod is connected to an inner support plate through a rotating shaft. The inner support plate is connected to a second connecting rod through a rotating shaft.

[0007] Preferably, the straightening and blanking mechanism includes a placement rack installed at the top of the outer wall of the mounting frame. A blanking opening is installed at the top of the outer wall of the placement rack. A cylinder is installed on the inner wall of the placement rack. Sliding plates are movably installed on the inner walls of the placement rack. Blanking grooves are installed at the bottoms of the outer walls of the sliding plates. Flap plates are movably installed at the bottoms of the outer walls of the blanking grooves. Bottom plates are installed on both sides of the outer wall of the placement rack.

[0008] Preferably, the linkage rack is installed in an equidistant segmented manner, and the tooth grooves of the linkage rack are all meshed with the tooth grooves of the linkage gear.

[0009] Preferably, a cavity is provided on the inner wall of the bottom bracket, and the diameter of the stress footrest is adapted to the diameter of the cavity of the bottom bracket.

[0010] Preferably, a cavity is provided on the inner wall of the linkage block, and the diameter of the cavity of the linkage block is adapted to the diameter of the mounting post.

[0011] Preferably, one end of the first connecting rod is movably connected to the outer wall of the linkage block through a rotating shaft, and the other end of the first connecting rod is movably connected to the outer wall of the inner support plate through a rotating shaft. The inner support plate and the linkage block are in transmission connection through the first connecting rod.

[0012] Preferably, the other end of the second connecting rod is movably connected to the outer wall of the inner cylinder through a rotating shaft, and the second connecting rods are evenly arranged in a row on the outer wall of the inner cylinder.

[0013] Preferably, a chute is provided on the inner wall of the placement rack, and the sliding plate is movably installed in the chute of the placement rack.

[0014] Preferably, the diameter of the inner wall of the blanking groove is adapted to the diameter of the blanking port, and the bottom of the blanking groove is aligned with the top of the inner cylinder.

[0016] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) Through the cooperation of the bracket positioning mechanism, the welding arm and the linkage rack provided in the present invention, the welding efficiency of the bracket can be greatly improved. In the traditional bracket welding process, the bracket needs to be transported. After transportation, the bracket needs to be manually placed at the welding place for welding. After welding, the bracket also needs to be taken out. Such a process greatly reduces the welding efficiency of the bracket. However, in the present invention, the conveyor belt drives the bracket on the bracket positioning mechanism to be automatically fixed, rotated and welded, so that the bracket can be welded during transportation. This greatly improves the welding efficiency of the bracket, reduces a certain amount of labor cost at the same time, and the bracket does not need to be manually fixed and can be adjusted by the bracket positioning mechanism itself, saving many steps, making the welding process of the bracket integrated, and not reducing the welding quality of the bracket while improving the welding efficiency of the bracket; (2) Through the cooperation of the bracket positioning mechanism, the straight-down feeding mechanism and the conveyor belt, the welding process of the bracket in the present invention not only improves the efficiency but also becomes safer. When the welded bracket moves to the bottom of the conveyor belt, it will slide into the interior of the receiving bin by gravity for collection. At the same time, the straight-down feeding mechanism enables the staff to simply place the bracket 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, it is necessary for workers to manually place the bracket at the welding position and then remove it after welding. However, the present invention simplifies many steps and does not require manual intervention. The staff only needs to regularly place the bracket from the feeding port, and then the present invention can automatically complete the subsequent welding work, which not only saves labor costs but also guarantees the safety of the staff.

On the outer walls of the conveyor belt outer shells 102, there are side brackets 103. On one side of the conveyor belt 101, there is a material receiving bin 104. On the other side of the conveyor belt 101, there is an installation frame 105. At the top of the outer wall of the side bracket 103, there is a welding arm 106. On the outer wall of the conveyor belt outer shell 102, there is a linkage rack 107. On the outer wall of the conveyor belt 101, there is a bracket positioning mechanism 2 for fixing the compressor bracket and cooperating with welding. At the top of the outer wall of the installation frame 105, there is an alignment and blanking mechanism 3 for blanking the compressor bracket. The bracket positioning mechanism 2 includes a linkage gear 201 movably connected to the outer wall of the conveyor belt 101 through a rotating shaft. On the outer wall of the linkage gear 201, there is a chassis 202. On the outer wall of the chassis 202, there is a bottom bracket 203. One end of the bottom bracket 203 is connected to an inner cylinder 204. Inside the inner wall of the inner cylinder 204, there is an inner plate 205. On the outer wall of the inner plate 205, there is an installation column 206. On the outer wall of the installation column 206, there is a linkage block 207 movably installed. At the top of the outer wall of the linkage block 207, there is a return spring 208. On the outer walls of the linkage block 207, there are force-bearing footrests 209. On the outer walls of the linkage block 207, there are first connecting rods 210 movably connected through rotating shafts. One end of the first connecting rod 210 is connected to an inner support plate 211 through a rotating shaft. On the outer wall of the inner support plate 211, there is a second connecting rod 212 connected through a rotating shaft.

[0022] The alignment and blanking mechanism 3 includes a placement rack 301 installed at the top of the outer wall of the installation frame 105. At the top of the outer wall of the placement rack 301, there is a blanking port 302. Inside the placement rack 301, there is a cylinder 303. Inside the placement rack 301, there are sliding plates 304 movably installed. At the bottom of the outer walls of the sliding plates 304, there are blanking grooves 305. At the bottom of the outer walls of the blanking grooves 305, there are flap plates 306 movably installed. On both sides of the outer wall of the placement rack 301, there are bottom plates 307.

[0023] The linkage rack 107 is installed in an equidistant segmented manner. The tooth grooves of the linkage rack 107 are all meshed with the tooth grooves of the linkage gear 201. Since the linkage rack 107 is installed in a segmented equidistant manner, every time the linkage gear 201 moves to the position of the linkage rack 107, it can rotate equidistantly.

[0024] There is a cavity inside the bottom bracket 203. The diameter of the force-bearing footrest 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 footrest 209 to move downward in the cavity of the bottom bracket 203.

[0025] The inner wall of the linkage block 207 is provided with a cavity, the diameter of the cavity of the linkage block 207 is matched with the diameter of the mounting column 206 , and the linkage block 207 can slide on the outer wall of the mounting column 206 .

[0026] One end of the No. 1 connecting rod 210 is movably connected to the outer wall of the linkage block 207 via 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 via 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.

[0027] The other end of the No. 2 connecting rod 212 is movably connected to the outer wall of the inner cylinder 204 through a rotating shaft. The No. 2 connecting rods 212 are evenly arranged on the outer wall of the inner cylinder 204. When the inner support plate 211 moves, it will drive the No. 2 connecting rod 212 to rotate.

[0028] 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.

[0029] The diameter of the inner wall of the material discharge chute 305 matches the diameter of the material discharge port 302 , the bottom of the material discharge chute 305 is aligned with the top of the inner cylinder 204 , and the bracket sliding down the material discharge chute 305 will just cover the outside of the inner cylinder 204 .

[0030] 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.

[0031] The working principle and use 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 held 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 plate 304 will slide in the slide groove of the inner wall of the placement rack 301. When the discharge chute 305 slides to a certain position, the flap 306 will open because there is no support from the bottom plate 307. After the flap 306 is opened, the bracket on the inner wall of the discharge chute 305 will slide out, and the bracket that slides out will fall on the outer wall of the slide plate 304. 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 bracket 209, and the weight of the bracket itself will drive the force-bearing bracket 209 to move downward in the cavity of the bottom bracket 203. When the force-bearing bracket 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 present an open movement 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 can support the inner wall of the bracket to fix the bracket; Finally, after the bracket is fixed, the user starts the conveyor belt 101. After the conveyor belt 101 is started, it will drive the linkage gear 201 to move synchronously. After moving to a certain distance, the linkage gear 201 will mesh 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.

[0032] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope 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 essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
