Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a clamping device for processing an automobile air-conditioning compressor housing. Background Technique

[0002] The automobile air-conditioning compressor is the heart of the automobile air-conditioning refrigeration system, playing the role of compressing and transporting refrigerant vapor. The compressor is divided into two types: non-variable displacement and variable displacement. According to different working principles, the air-conditioning compressor can be divided into a fixed-displacement compressor and a variable-displacement compressor.

[0003] There are various types and specifications of existing processing clamping devices. For example, a clamping device for processing automobile parts with the Chinese patent number CN211491175U. In this technical solution, by driving a double-shaft hydraulic cylinder, the movable shafts on both sides are extended, thereby pushing the driving rod. Also, since the top of the driving rod is hinged to the push rod through a driving head, and the driving head is hinged to the stabilizing frame through a hinge plate, when the driving rod is pushed, the angle is adjusted, thereby driving the expansion of the angle between the driving head and the hinge plate. The driving head pushes towards the vertical line of the working box, and the angle between the driving head and the push rod is adjusted through the hinge rod, so that the driving head drives the push rod to horizontally move towards the center, thereby realizing the reduction of the distance between the two clamping plates and clamping and fixing the automobile parts. The overall structure is simple, achieving the purpose of good clamping effect of the device, avoiding the displacement of parts during processing, improving the processing quality of parts, and being convenient to use. However, this technical solution still has deficiencies in actual application. Since there is no adjustment structure at the bottom of this technical solution, when the workpiece needs to adjust the processing angle, manual operation is required. This method not only consumes manpower but also greatly affects the processing efficiency. Moreover, the clamping method of this device is only clamping and fixing on both sides, and the fixing effect is not good, and it is easy for the workpiece to displace during processing, resulting in affecting the processing efficiency. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a clamping device for processing an automobile air-conditioning compressor housing, which has the advantages of a rotating function and strong clamping stability, and solves the problems of manual adjustment of the processing angle and poor clamping and fixing effect.

[0005] To achieve the above-mentioned purposes of a rotating function and strong clamping stability, the utility model provides the following technical solution: A clamping device for processing an automobile air-conditioning compressor housing, including a first equipment box and a second equipment box. The second equipment box is installed on the top of the first equipment box. A rotating mechanism is arranged inside the first equipment box, and a clamping and fixing mechanism is arranged inside the second equipment box;

[0006] The rotating mechanism includes a concave disc and a servo motor. The concave disc and the servo motor are fixedly installed inside the first equipment box. A rotating rod is rotatably connected to the top of the concave disc. A driven gear disc is fixedly connected to the top of the rotating rod. One end of the output shaft of the servo motor is fixedly connected to a driving gear. A plurality of support rods are fixedly installed at the bottom of the driven gear disc. Sliding wheels are arranged at the bottoms of the plurality of support rods. An extension column is fixedly installed at the top of the driven gear disc. A mounting plate is fixedly connected to the top of the extension column.

[0007] Furthermore, circular chutes adapted to the widths of the support rods are formed in the concave disc. The inner walls of the circular chutes are slidably connected to the plurality of sliding wheels. The driving gear and the driven gear disc are meshed with each other, and the connection relationship is a meshing connection.

[0008] Furthermore, the shape of the mounting plate is circular. The area of the mounting plate is larger than that of the driven gear disc and the concave disc. A circular hole groove with the same area as the mounting plate is formed in the top of the first equipment box. The top of the mounting plate is fixedly connected to the bottom of the second equipment box.

[0009] Furthermore, the clamping and fixing mechanism includes a bidirectional motor and an auxiliary rod. The bidirectional motor and the auxiliary rod are fixedly installed inside the second equipment box. Bearings are fixedly installed on the left and right sides of the inner wall of the second equipment box. The output ends on both sides of the bidirectional motor are fixedly connected to the inner walls of the two bearings with threaded rods. The outer parts of the two threaded rods and the left and right sides of the auxiliary rod are movably connected with sliders extending to the outside of the second equipment box. One end of each of the two sliders extending to the outside of the second equipment box is fixedly connected to a connecting plate. Two limit plates are fixedly installed on the top of each of the two connecting plates. Electric telescopic rods are fixedly installed on the opposite surfaces of the two limit plates. The telescopic ends of the electric telescopic rods are fixedly installed with L-shaped clamping plates.

[0010] Furthermore, the front two sliders are respectively threadedly connected to the outer parts of the two threaded rods, and the rear two sliders are slidably connected to the outer part of the auxiliary rod. Two chutes adapted to the sliders are formed in the second equipment box.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0013] 1. The clamping device for machining the automotive air-conditioning compressor housing is provided with a rotating mechanism. The output end of the servo motor drives the driving gear to rotate. Due to the meshing connection between the driving gear and the driven gear disc, the driven gear disc is also driven to rotate on the concave disc. The multiple support rods and sliding wheels at the bottom also slide in the circular chute of the concave disc, improving its stability during rotation, achieving the purpose of rotating the equipment above the driven gear disc, reducing labor consumption, further enhancing its processing efficiency, and having relatively high stability during equipment operation.

[0014] 2. The clamping device for machining the automotive air-conditioning compressor housing is provided with a clamping and fixing mechanism. The output shafts at both ends of the bidirectional motor inside the second equipment box cooperate with the bearings on the left and right sides, enabling the two threaded rods to rotate stably. At the same time, the two front sliders threadedly connected to the outer parts of the two threaded rods also move relatively or away from each other through their stable rotation. Since the two rear sliders are slidably connected to the auxiliary rods, when the two front sliders move, through the connection of their respective connecting plates, the sliders at the corresponding positions on the rear side can be driven to move in the same way. While moving, the four L-shaped clamping plates on the connecting plates also move left and right correspondingly. Thus, the purpose of clamping and fixing on the left and right sides of this mechanism is achieved. After the left and right sides are firmly fixed, by moving the telescopic ends of the four electric telescopic rods, the front and rear sides of the workpiece to be clamped can also be clamped and fixed. This mechanism uses a four-sided clamping method to fix the workpiece, with relatively strong clamping stability, which can effectively prevent some workpieces from shifting or displacing, indirectly improving the processing efficiency of this equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , a clamping device for machining an automotive air-conditioning compressor housing in this embodiment includes a first equipment box 1 and a second equipment box 2. The second equipment box 2 is installed on the top of the first equipment box 1. A rotating mechanism 3 is arranged inside the first equipment box 1, and a clamping and fixing mechanism 4 is arranged inside the second equipment box 2;

[0022] The rotating mechanism 3 includes a concave disk 301 and a servo motor 302. The concave disk 301 and the servo motor 302 are fixedly installed inside the first equipment box 1. A rotating rod 303 is rotatably connected to the top of the concave disk 301. A driven gear disk 304 is fixedly connected to the top of the rotating rod 303. One end of the output shaft of the servo motor 302 is fixedly connected to a driving gear 307. The driving gear 307 meshes with the driven gear disk 304, and the connection relationship is a meshing connection. By driving the driving gear 307 to rotate through the output end of the servo motor 302, and then through the meshing connection relationship between the driving gear 307 and the driven gear disk 304, the driven gear disk 304 is also driven to rotate on the concave disk 301. A plurality of support rods 305 are fixedly installed at the bottom of the driven gear disk 304. Circular chutes adapted to the width of the support rods 305 are opened on the concave disk 301. Sliding wheels 306 are arranged at the bottoms of the plurality of support rods 305. The inner wall of the circular chute is slidably connected to the plurality of sliding wheels 306. Thus, the plurality of support rods 305 and the sliding wheels 306 at the bottom can slide in the circular chute of the concave disk 301, improving the stability during rotation. A extension column 308 is fixedly installed at the top of the driven gear disk 304. The top of the extension column 308 is fixedly connected to a mounting plate 309. The top of the mounting plate 309 is fixedly connected to the bottom of the second equipment box 2. When the driven gear disk 304 rotates, the equipment above is also driven to rotate, achieving the purpose of equipment rotation. Thereby, the labor consumption is reduced, the processing efficiency is further improved, and the stability during equipment operation is also relatively high.

[0023] In the case implementation, the shape of the mounting plate 309 is circular, and the area of the mounting plate 309 is larger than that of the driven gear disc 304 and the concave disc 301. A circular hole groove with the same area as the mounting plate 309 is provided at the top of the first equipment box 1. This design can not only improve the flexibility of the equipment, but also enable the mounting plate 309 to serve as a baffle for the first equipment box 1, reducing the entry of some dust or impurities into the internal equipment and increasing the service life of the equipment.

[0024] In the case implementation, the clamping and fixing mechanism 4 includes a bidirectional motor 401 and an auxiliary rod 404. The bidirectional motor 401 and the auxiliary rod 404 are fixedly installed inside the second equipment box 2. Bearings 402 are fixedly installed on both the left and right sides of the inner wall of the second equipment box 2. Threaded rods 403 are fixedly connected to the inner walls of the two bearings 402 at both output ends of the bidirectional motor 401. By the cooperation of the output shafts at both ends of the bidirectional motor 401 inside the second equipment box 2 and the bearings 402 on the left and right sides, the two threaded rods 403 can rotate stably. Sliders 405 extending outside the second equipment box 2 are movably connected to the left and right sides of the auxiliary rod 404 and the outer parts of the two threaded rods 403. Among them, the front two sliders 405 are respectively threadedly connected to the outer parts of the two threaded rods 403. When the threaded rods 403 rotate stably, the front two sliders threadedly connected to their outer parts will also move relatively or away from each other through their stable rotation. The inner parts of the rear two sliders 405 are slidably connected to the outer part of the auxiliary rod 404. One end of both sides of the sliders 405 extending outside the second equipment box 2 is fixedly connected to a connecting plate 406. Due to the sliding connection relationship between the rear two sliders 405 and the auxiliary rod 404, after the front two sliders 405 move, through the connection of their respective connecting plates 406, the sliders 405 at the corresponding positions on the rear side can be driven to move in the same way. Two limit plates 407 are fixedly installed on the top of the two connecting plates 406. Electric telescopic rods 408 are fixedly installed on the opposite surfaces of the two limit plates 407. The telescopic ends of the electric telescopic rods 408 are fixedly installed with L-shaped clamping plates 409. When the front sliders 405 move, the four L-shaped clamping plates 409 on the connecting plate 406 will also move left and right correspondingly. Thus, the purpose of clamping and fixing on the left and right of this mechanism is achieved. After the left and right sides are firmly fixed, by moving the telescopic ends of the four electric telescopic rods 408, the front and rear sides of the workpiece to be clamped can also be clamped and fixed. This mechanism uses a four-sided clamping method to fix the workpiece, and its clamping stability is strong, which can effectively prevent some workpieces from shifting or displacing, indirectly improving the processing efficiency of this equipment.

[0025] In the case implementation, two chutes adapted to the sliders 404 are provided on the second equipment box 2 to make the equipment run more smoothly.

[0026] In the case implementation, a placement table 5 is fixedly installed on the top of the second equipment box 2, where the workpieces to be clamped can be placed on it. A power connection port 6 is provided on the right side of the first equipment box 1, which can be connected to a power source to supply power to the equipment. A controller 7 is fixedly installed on the front side of the first equipment box 1. The controller 7 and the electronic components in this patent are all electrically connected by wires, so as to facilitate operating the controller 7 to control the operation of the electronic components.

[0027] During implementation, the operations are carried out according to the following steps:

[0028] 1) First, connect the power connection port 6 to the power supply equipment;

[0029] 2) Then, place the workpieces to be fixed on the placement table 5;

[0030] 3) Next, start the equipment by operating the controller 7;

[0031] 4) Finally, fix and clamp the workpieces by controlling the clamping and fixing mechanism 4.

[0032] In summary, for this machining clamping device for the automotive air-conditioning compressor housing, by setting the rotating mechanism 3, the output end of the servo motor 302 drives the driving gear 307 to rotate. Then, due to the meshing connection relationship between the driving gear 307 and the driven gear disk 304, the driven gear disk 304 is also driven to rotate on the concave disk 301. The multiple support rods 305 and sliding wheels 306 at the bottom also slide in the circular chute of the concave disk 301, improving its stability during rotation and achieving the purpose of rotating the equipment above the driven gear disk 304, reducing the human consumption, further enhancing its machining efficiency, and having relatively high stability during the operation of the equipment. It solves the problem that there is no adjustment structure at the bottom of this technical solution, resulting in the need for manual operation when the workpieces need to be adjusted in the machining angle, which not only consumes human resources but also greatly affects the machining efficiency.

[0033] Moreover, by setting the clamping and fixing mechanism 4, the output shafts at both ends of the bidirectional motor 401 inside the second equipment box 2 cooperate with the bearings 402 on the left and right sides, enabling the two threaded rods 403 to rotate stably. At the same time, the two front sliders 405 threadedly connected to the outer sides of the two threaded rods 403 will also move relatively or away from each other due to their stable rotation. Since the two rear sliders 405 are slidably connected to the auxiliary rods 404, after the two front sliders 405 move, through the connection of their respective connecting plates 406, the sliders 405 at the corresponding positions on the rear side can be driven to move in the same way. While moving, the four L-shaped clamping plates 409 on the connecting plates 406 will also move correspondingly left and right. Thus, the purpose of clamping and fixing on the left and right sides of this mechanism is achieved. After the left and right sides are firmly fixed, by moving the telescopic ends of the four electric telescopic rods 408, the front and rear sides of the workpiece to be clamped can also be clamped and fixed. This mechanism uses a four-sided clamping method to fix the workpiece, with strong clamping stability, which can effectively prevent some workpieces from shifting or displacing, indirectly improving the processing efficiency of this equipment and solving the problem that the clamping method of this device is only two-sided clamping and fixing, with poor fixing effect, and it is very easy for the workpiece to displace during processing, resulting in the problem of affecting the processing efficiency.
