Description

Technical Field

[0001] This application relates to the field of air conditioner compressor housing processing technology, specifically to a tube expansion and shaping mechanism for air conditioner compressor housing components. Background Technology

[0002] The air conditioner compressor is the core component of the air conditioning refrigeration system. Its function is similar to that of the human heart, driving the entire refrigeration cycle by circulating and compressing the refrigerant. It is usually installed in the outdoor unit, and its working circuit is divided into an evaporation zone and a condensation zone. It achieves the suction, compression, and transportation of refrigerant by changing its internal volume. The components on the air conditioner compressor housing (such as pipes) need to be expanded and shaped during the manufacturing process.

[0003] Currently, manual operation still dominates the production process of pipe expansion and shaping: workers must first manually pick up the pipe and precisely place it on the expansion head of the expansion machine; after the expansion head completes the radial expansion of the pipe, the worker manually removes the pipe from the equipment. However, there are significant safety hazards in this process—because the expansion head and the pipe need to maintain high-intensity compression contact during the processing stage to achieve precise shaping of the pipe end, if the worker is slightly negligent (such as improper timing of picking up and placing or hand position deviation), fingers may be caught in the gap between the expansion head and the pipe, causing mechanical injury accidents, which pose certain safety hazards. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose a tube expansion and shaping mechanism for an air conditioner compressor housing assembly, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a pipe expanding and shaping mechanism for an air conditioner compressor housing assembly, including a base frame, on which an expanding machine is fixedly installed. An expanding head is provided on the top of the expanding machine. A collection bucket is provided on the base frame. A vertical rod is fixedly connected to the top of the base frame. A longitudinal moving frame is slidably connected to the outer surface of the vertical rod through a lifting mechanism. A transverse moving platform is slidably connected to the outer surface of the longitudinal moving frame through a translation mechanism. A frame is fixedly connected to the bottom of the transverse moving platform. An adaptive gripper mechanism for timely clamping and releasing of the pipe is provided on the frame.

[0006] Preferably, the lifting mechanism includes a first guide rod fixedly connected to the base frame, and the outer surface of the first guide rod is slidably connected to the inner surface of the longitudinal frame. A first motor is fixedly installed on the top of the base frame, and a first lead screw is fixedly connected to the output end of the first motor. The first lead screw passes through the inner side of the longitudinal frame and is threadedly engaged. The lifting mechanism can perform timely lifting operations on the adaptive gripper mechanism.

[0007] Preferably, the translation mechanism includes a second guide rod fixedly connected to the inner side of the longitudinal frame, and the outer surface of the second guide rod is slidably connected to the inner surface of the transverse stage. A second motor is fixedly installed on the longitudinal frame, and a second lead screw is fixedly connected to the output end of the second motor. The second lead screw passes through the inner side of the transverse stage and is threadedly engaged. The translation mechanism can perform timely horizontal movement operation on the adaptive gripper mechanism.

[0008] Preferably, the adaptive gripper mechanism includes a motor fixedly mounted on a frame, the output end of the motor is fixedly connected to a drive shaft, and the bottom end of the drive shaft is rotatably connected to an alignment recess. The adaptive gripper mechanism can clamp or release the pipe at an appropriate time.

[0009] Preferably, a rotating disk is fixedly sleeved on the outer surface of the drive shaft, and a guide arc hole is formed on the outer surface of the rotating disk.

[0010] Preferably, a displacement clamping arm is slidably connected to the inner side of the frame, a guide shaft is fixedly connected to the outer surface of the displacement clamping arm, and the outer surface of the guide shaft is slidably connected to the guide arc hole. A V-shaped clamping plate is provided at the end of the displacement clamping arm away from the frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The air conditioner compressor housing assembly uses a pipe expanding and shaping mechanism. During the entire pipe expanding and shaping process, workers only need to manually support the pipe for stability in the first step. The entire subsequent process does not require manual intervention. From the precise positioning and stable clamping of the pipe, to the lifting and moving of the pipe and its automatic placement on the expanding head, and then to the collection of the pipe after the expanding and shaping is completed, each step is automatically completed by the mechanical device. Workers will not have any contact with the expanding machine or the expanding head throughout the process, completely eliminating the risk of fingers being caught in the gap and significantly reducing safety hazards.

[0013] 2. The air conditioner compressor housing assembly uses a pipe expansion and shaping mechanism. Through a lifting mechanism, a translation mechanism, and an adaptive gripper mechanism, it achieves a high degree of precision and stability in operation. These mechanical devices work together in a coordinated and interlocking manner, which can quickly and accurately complete the pipe expansion and shaping process, avoiding errors and uncertainties caused by excessive manual intervention, and ensuring the consistency of the quality of pipe expansion and shaping.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1-6 A pipe expanding and shaping mechanism for an air conditioner compressor housing assembly includes a base frame 1, an expanding machine 2 fixedly mounted on the base frame 1, an expanding head 3 provided on the top of the expanding machine 2, and a pipe sleeve being expanded and shaped outside the expanding head 3. A collection bucket 4 is provided on the base frame 1, a vertical rod 5 is fixedly connected to the top of the base frame 1, a longitudinal moving frame 6 is slidably connected to the outer surface of the vertical rod 5 through a lifting mechanism, a transverse moving platform 13 is slidably connected to the outer surface of the longitudinal moving frame 6 through a translation mechanism, a platform 14 is fixedly connected to the bottom of the transverse moving platform 13, and an adaptive gripper mechanism for timely clamping and releasing of the pipe is provided on the platform 14.

[0023] Through the above technical solution, during the expansion and forming process of the pipe on the air conditioner compressor housing, the top of the pipe needs to be manually clamped onto the alignment recess 17. Then, the pipe is stably clamped by the adaptive gripper mechanism (it can be released after clamping). During this process, the pipe can be accurately fitted onto the expansion head 3 by the lifting mechanism and the translation mechanism. At the same time, the longitudinal frame 6 can be moved upward while the pipe is released. After the expansion head 3 is expanded and shaped, the adaptive gripper mechanism is moved down to a suitable position by the lifting mechanism to stabilize the pipe. Finally, the pipe is moved upward and moved to a suitable height above the collection bucket 4 by the translation mechanism. It is then put into the collection bucket 4 to complete the entire expansion and shaping operation. During the whole process, the lifting mechanism, translation mechanism and adaptive gripper mechanism need to be used frequently at appropriate times. The entire process only requires manual operation when clamping the pipe in the first step. No manual intervention is required afterward. The worker will not come into contact with the expansion machine 2 and the expansion head 3 throughout the process, which significantly reduces safety hazards.

[0024] Specifically, the lifting mechanism includes a first guide rod 7 fixedly connected to the base frame 1, and the outer surface of the first guide rod 7 is slidably connected to the inner surface of the longitudinal frame 6. A first motor 8 is fixedly installed on the top of the base frame 1, and a first lead screw 9 is fixedly connected to the output end of the first motor 8. The first lead screw 9 passes through the inner side of the longitudinal frame 6 and is threadedly engaged.

[0025] Through the above technical solution, under the relative limiting action of the first guide rod 7, when the first lead screw 9 rotates, it will drive the longitudinal moving frame 6 that is meshed with it to move along the axial direction of the first lead screw 9, that is, the longitudinal moving frame 6 will move up and down.

[0026] Specifically, the translation mechanism includes a second guide rod 10 fixedly connected to the inner side of the longitudinal frame 6, and the outer surface of the second guide rod 10 is slidably connected to the inner surface of the transverse stage 13. A second motor 11 is fixedly installed on the longitudinal frame 6, and a second lead screw 12 is fixedly connected to the output end of the second motor 11. The second lead screw 12 passes through the inner side of the transverse stage 13 and is threadedly engaged.

[0027] Through the above technical solution, the second guide rod 10 plays a relative limiting role on the transverse stage 13. During the process of the second motor 11 driving the second lead screw 12 to rotate, the second lead screw 12 will drive the transverse stage 13, which is meshed with it, to move horizontally.

[0028] Specifically, the adaptive gripper mechanism includes a motor 15 fixedly mounted on the frame 14, a drive shaft 16 fixedly connected to the output end of the motor 15, and an alignment recess 17 rotatably connected to the bottom end of the drive shaft 16.

[0029] Using the above technical solution, starting motor 15 can drive drive shaft 16 to rotate, and during this time, rotating disk 18 will also rotate synchronously. It should be noted that... Figure 1As shown, when the transverse stage 13 moves to the leftmost position (and cannot move further to the left), the alignment recess 17 is directly facing the lower expansion head 3.

[0030] Specifically, a rotating disk 18 is fixedly sleeved on the outer surface of the drive shaft 16, and a guide arc hole 19 is opened on the outer surface of the rotating disk 18.

[0031] Through the above technical solution, five sets of guide arc holes 19 are opened on the outer surface of the rotating disk 18, and the five sets of guide arc holes 19 are symmetrically distributed on the surface of the rotating disk 18. The corresponding guide shaft 21 and displacement clamping arm 20 and other components are also provided in five sets, and are also evenly distributed on the stand 14, respectively cooperating with the corresponding guide arc holes 19.

[0032] Specifically, a shifting clamping arm 20 is slidably connected to the inner side of the frame 14, and a guide shaft 21 is fixedly connected to the outer surface of the shifting clamping arm 20. The outer surface of the guide shaft 21 is slidably connected to the guide arc hole 19, and a V-shaped clamping plate 22 is provided at the end of the shifting clamping arm 20 away from the frame 14.

[0033] Through the above technical solution, the V-shaped clamp 22 is set at the end of the shifting clamp arm 20 away from the platform 14. There are five sets of them, which are evenly distributed below the alignment recess 17. When clamping the pipe, they will move closer to each other until they are clamped on the surface of the pipe. In addition, the V-shaped design of the V-shaped clamp 22 can adapt to pipes of various sizes.

[0034] Working principle: During the expansion and forming process of the pipe on the air conditioner compressor housing, the second motor 11 needs to be turned on first to drive the second lead screw 12 to rotate. Under the relative limiting action of the second guide rod 10, the transverse moving table 13 can move to the left along the surface of the longitudinal moving frame 6 (i.e., the operation process of the translation mechanism). When the transverse moving table 13 moves to the leftmost position ( Figure 1As shown in the diagram, the alignment recess 17 is directly opposite the expansion head 3 below. At this point, the tube needs to be manually removed and its top end clamped into the alignment recess 17. Then, the motor 15 is turned on to drive the drive shaft 16 and the rotating disk 18 to rotate (during this process, the drive shaft 16 and the alignment recess 17 will also rotate, so the tube needs to be held firmly). During the rotation of the rotating disk 18, the guide arc hole 19 on its surface will also make a circular motion. During this process, the guide arc hole 19 will drive the guide shaft 21 during the offset process (during this process, the guide shaft 21 will slide along the guide arc hole 19). In turn, by driving the guide shaft 21, the corresponding displacement clamping arm 20 will be moved synchronously. During this process, the five sets of shifting clamping arms 20 will drive the V-shaped clamping plates 22 at the other end to synchronously approach the pipe until the five sets of V-shaped clamping plates 22 are evenly and stably clamped on the outer surface of the pipe, making the pipe stable. At this time, the pipe can be released. Then, the first motor 8 is turned on to drive the first lead screw 9 to rotate. The first lead screw 9 drives the longitudinal shifting frame 6, causing the longitudinal shifting frame 6 to gradually slide down along the surface of the upright 5 (i.e., the lifting mechanism is in operation). During this time, the pipe will move down synchronously until the pipe moves down to partially cover the expansion head 3. At this time, the adaptive gripper mechanism can release the clamping restriction on the pipe, allowing the pipe to automatically fall off and cover the expansion head. 3. In addition, under the action of the lifting mechanism, the adaptive gripper mechanism is moved up to a height that will not hinder the pipe expansion and shaping. After the expansion machine 2 and the expansion head 3 complete the pipe expansion and shaping, the V-shaped clamp 22 is moved down to a suitable position by the lifting mechanism. Then, the adaptive gripper mechanism is used to make the V-shaped clamp 22 re-clamp the pipe. After the pipe is stably clamped, the pipe can be raised again by the lifting mechanism to a height away from the expansion head 3. Finally, the horizontal moving platform 13 is slid to the right along the longitudinal moving frame 6 by the translation mechanism. When the horizontal moving platform 13 moves to the rightmost side of the longitudinal moving frame 6 (and cannot move further to the right), the clamped pipe is at this time Facing the collection bucket 4 below, the vertical moving frame 6 can then use the lifting mechanism to move the pipe down a certain distance (bringing the pipe closer to the collection bucket 4 to prevent damage caused by excessive height when the pipe is placed into the collection bucket 4 later). Then, the adaptive gripper mechanism releases the pipe, allowing it to fall into the collection bucket 4, completing the collection of the expanded and shaped pipe. In the entire pipe expansion and shaping process, only the first step requires manual support to stabilize the pipe. There is no further manual intervention in the entire process, and the worker will not come into contact with the expansion machine 2 or the expansion head 3 throughout the process. Therefore, there is no risk of getting their hand caught, significantly reducing safety hazards.
