Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to an integrated processing device for automotive air conditioning pipes. Background Technology

[0002] As a key fluid transmission component in the vehicle's thermal management system, the processing quality of automotive air conditioning rigid pipes directly determines the airtightness, cooling efficiency, and assembly compatibility of the air conditioning system. These pipes require three core processes: precise drilling, burr-free cutting, and cold bending. With the increasing trend of large-scale mass production in the automotive manufacturing industry, the market has placed higher demands on the efficiency, precision, and automation level of air conditioning rigid pipe processing, and the drawbacks of traditional processing methods are becoming increasingly apparent.

[0003] Currently, the processing of automotive air conditioning rigid pipes is still mainly based on decentralized processes, relying on the combined operation of multiple single-function equipment. Specialized drilling machines are used to drill holes, independent cutting machines are used to cut the pipes, and hydraulic bending machines are used to cold bend them at 60°. In this processing mode, the pipes need to be repeatedly transferred between multiple machines by manual labor or simple conveying devices. After each process is completed, they need to be repositioned and clamped. This not only increases the labor intensity, but also causes cumulative errors due to repeated positioning, resulting in poor product dimensional consistency. Even though some manufacturers have launched preliminary integrated processing equipment, they have only achieved physical splicing of processes and have not achieved deep integration of core functions. For example, cutting and drilling still require switching between different workstations or changing processing components, and the pipes need to be repositioned inside the equipment. Positioning errors cannot be completely eliminated, and the switching process prolongs the processing cycle, making it difficult to meet the needs of large-scale production.

[0004] As the automotive industry transforms towards integration and efficiency, traditional processing methods can no longer meet the market demands for high precision, high consistency, and high capacity. Developing a device that can integrate drilling, cutting, and bending processes to achieve integrated processing has become an urgent task to solve existing technical pain points and improve the processing quality and efficiency of automotive air conditioning hard pipes.

A similar moving block is slidably connected on the arc-shaped guide rail. The moving block on the arc-shaped guide rail is fixedly connected to the output end of the swing motor. A mandrel mounting block is fixedly connected to the moving block on the arc-shaped guide rail, and a telescopic mandrel is fixedly connected to the mandrel mounting block.

[0010] Preferably, the clamping surfaces of the compression plate and the transverse clamping block are both fixedly connected with clamping pads.

[0011] Preferably, the lead screw is a ball screw, the moving block slides against the inner wall of the moving groove, and the moving block is provided with an internal threaded hole adapted to the ball screw.

[0012] Preferably, the rotation angle range of the rotating rod is 0-180°, and it can self-lock after rotating into position.

[0013] Preferably, the telescopic mandrel's extension stroke is adapted to the length of the pipe groove, and the diameter of the telescopic mandrel is smaller than the inner diameter of the pipe to be processed.

[0014] Preferably, the arc of the arc-shaped guide rail corresponds to a 60° bending angle, and the outer wall of the arc-shaped guide rail is provided with a wear-resistant coating.

[0015] Preferably, the motor, telescopic air pump, and swing motor are all electrically connected to an external PLC control system.

[0016] Preferably, the inner wall of the groove is arc-shaped.

[0017] Preferably, the vertical fixing device is located at the tail of the pipe fitting to be processed, and the horizontal clamping block is located in the middle of the pipe fitting to be processed.

[0018] Preferably, the processing and mounting block is provided with two drive motors, and the output ends of the two drive motors are respectively fixedly connected to the cutting blade and the drilling bit.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This integrated processing device for automotive air conditioning pipes completely solves the pain points of existing technologies, such as scattered processes and the need for manual handling of pipes, through its integrated clamping, processing, and bending structure design. Utilizing a pipe groove combined with a dual fixing structure of a vertical fixing device and a horizontal clamping block, precise positioning of the pipes is achieved. Simultaneously, the rotating rod allows for 180° switching between cutting blades and drilling bits. Combined with the position adjustment function of the telescopic rod and height adjustment block, drilling and cutting processes can be completed without disassembling the pipes. Subsequently, a bending mechanism driven by a telescopic mandrel built into the base and an arc-shaped guide rail simultaneously achieves 60° cold bending. This fully integrated processing significantly reduces repetitive positioning errors, improves product dimensional consistency, and greatly enhances processing efficiency compared to traditional distributed equipment.

[0021] 2. This integrated processing device for automotive air conditioning pipes optimizes the key structures for pipe fixing and bending. Compared to the shortcomings of existing technologies, such as unstable clamping and easy collapse during bending, this device uses a dual clamping method driven by a telescopic air pump and a servo motor, combined with the anti-slip and anti-scratch design of the clamping pads. This ensures no displacement during pipe processing and avoids damage to the pipe surface caused by hard clamping. At the same time, the telescopic mandrel can be inserted into the pipe to provide support, and the arc-shaped guide rail precisely limits the 60° bending trajectory, effectively controlling the pipe wall thinning rate and collapse problem. This meets the stringent assembly requirements of automotive air conditioning pipes and significantly improves the product qualification rate and reliability. Attached Figure Description

[0036] Please see Figure 1-8The present invention provides a technical solution: an integrated processing device for automotive air conditioning pipes, including a base 1, a pipe groove 2 is provided on the base 1, the inner wall of the pipe groove 2 is arc-shaped, vertical fixing devices 3 are fixedly connected to both sides of the pipe groove 2, a telescopic air pump 4 is fixedly connected to the vertical fixing device 3, a sliding rod 5 is fixedly connected to the output end of the telescopic air pump 4, and a compression plate 6 is fixedly connected to the lower part of the sliding rod 5.

[0037] The telescopic air pump 4 on the vertical fixing device 3 is started, and the output end pushes the sliding rod 5 to move downward, which drives the compression plate 6 to move downward in sync until the clamping soft pad 7 at the bottom of the compression plate 6 is tightly attached to the upper surface of the pipe fitting, thus completing the vertical fixing.

[0038] Two movable slots 8 are provided on both sides of the base 1. A lead screw 10 is threadedly connected to the movable slot 8. A motor 9 is fixedly connected to one end of the base 1. The output end of the motor 9 is fixedly connected to the lead screw 10. A movable block 11 is threadedly connected to the lead screw 10 in both movable slots 8. A transverse clamping block 12 is fixedly connected to each movable block 11.

[0039] The vertical fixing device 3 is located at the tail of the pipe fitting to be processed, and the horizontal clamping block 12 is located in the middle of the pipe fitting to be processed;

[0040] A processing base 13 is fixedly connected to one side of the tube groove 2. A telescopic rod 14 is slidably connected to the processing base 13. A height adjustment block 15 is fixedly connected to the telescopic rod 14. A rotating rod 16 is rotatably connected to one end of the height adjustment block 15. A processing mounting block 17 is fixedly connected to the rotating rod 16. A cutting blade 18 is rotatably connected to one end of the processing mounting block 17. A drilling bit 19 is rotatably connected to the other end of the processing mounting block 17. Two drive motors are provided inside the processing mounting block 17. The output ends of the two drive motors are fixedly connected to the cutting blade 18 and the drilling bit 19, respectively.

[0041] A swing motor 20 is fixedly connected inside the base 1. An arc-shaped guide rail 21 is also fixedly connected inside the base 1. The arc-shaped guide rail 21 has an arc of 60° and a wear-resistant coating on its outer wall. A moving block 11 is slidably connected to the arc-shaped guide rail 21. The moving block 11 is fixedly connected to the output end of the swing motor 20. A mandrel mounting block 22 is fixedly connected to the moving block 11. A telescopic mandrel 23 is fixedly connected to the mandrel mounting block 22. The diameter of the telescopic mandrel 23 is smaller than the inner diameter of the pipe to be processed.

[0042] Motor 9, telescopic air pump 4, and swing motor 20 are all electrically connected to an external PLC control system;

[0043] The output end of the swing motor 20 pushes the moving block 11 to slide in an arc along the arc guide rail 21. The mandrel mounting block 22 moves synchronously with the moving block 11, causing the telescopic mandrel 23 and the inserted tube to bend along the arc trajectory until the fixed bending is completed.

[0044] Both the compression plate 6 and the horizontal clamping block 12 have clamping pads 7 fixedly connected to their clamping surfaces.

[0045] Working principle: Before use, adjust the initial position of each component of the device according to the outer diameter and length specifications of the automotive air conditioning hard pipe to be processed. Rotate the rotating rod 16 to switch the working end of the processing mounting block 17. Select the cutting blade 18 or the drilling bit 19 to be in the working position according to the processing requirements. Then adjust the height of the height adjustment block 15 by the telescopic rod 14 so that the processing tool is aligned with the preset processing point.

[0046] After the processing is started, the operator places the hard pipe to be processed into the pipe groove 2 of the base 1, so that one end of the pipe fits against the positioning reference on the side of the processing base 13, completing the initial placement. Then, the telescopic air pump 4 on the vertical fixing device 3 is started, and the output end pushes the sliding rod 5 to move downward, driving the compression plate 6 to move downward synchronously until the clamping soft pad 7 at the bottom of the compression plate 6 is tightly attached to the upper surface of the pipe. At the same time, the motors 9 on both sides of the base 1 are started synchronously, and the output end drives the lead screw 10 in the moving groove 8 to rotate. Since the moving block 11 is threadedly connected to the lead screw 10, the rotation of the lead screw 10 drives the two moving blocks 11 to move relative to each other along the moving groove 8, thereby pushing the horizontal clamping block 12 closer to both sides of the pipe. The clamping soft pad 7 on the inner side of the horizontal clamping block 12 clamps the pipe from the horizontal direction. Through the dual fixing method of vertical downward pressure + horizontal clamping, combined with the anti-slip and anti-scratch function of the clamping soft pad 7, it is ensured that the pipe is not displaced or damaged during the processing, thus ensuring the processing accuracy.

[0047] If drilling is performed first, the drill bit 19, which is aligned with the preset hole position, starts to rotate. At the same time, the telescopic rod 14 slowly descends, driving the drill bit 19 to feed towards the pipe. After completing the precise drilling, the telescopic rod 14 drives the drill bit to retract and reset. If the cutting process needs to be switched, the processing mounting block 17 is rotated 180° by rotating the rotating rod 16, and the cutting blade 18 is switched to the working position. The height of the telescopic rod 14 is adjusted so that the cutting blade 18 is aligned with the preset cutting line. After the cutting blade 18 starts to rotate, the telescopic rod 14 advances to achieve burr-free cutting of the pipe. After the cutting is completed, the pipe is reset. During the processing, the drilling and cutting switching operations can be repeated as needed without disassembling the pipe, thus improving the continuity of processing.

[0048] After the drilling and cutting processes are completed, the telescopic mandrel 23 on the mandrel mounting block 22 is activated, extending towards the pipe and inserting into the part of the pipe to be bent. The mandrel supports the pipe wall to prevent it from collapsing and thinning during bending. Then, the swing motor 20 is activated, and the output end pushes the moving block 11 to slide in an arc along the arc guide rail 21. The swing motor 20 adopts a Panasonic MSMD042G1U+MADHT1507E swing servo motor, which adopts a servo swing drive mode. The swing angle is precise and controllable, and a 60° fixed bending can be stably achieved. The mandrel mounting block 22 moves synchronously with the moving block 11, driving the telescopic mandrel 23 and the pipe inserted therein to bend along the arc trajectory until the fixed bending is completed. During the bending process, the arc guide rail 21 ensures the consistency of the bending trajectory, and the uniform speed drive of the swing motor 20 ensures the accuracy of the bending angle and avoids springback deviation.

[0049] After all processing steps are completed, each component is reset in sequence. The telescopic mandrel 23 retracts, the swing motor 20 drives the moving block 11 back to its initial position, the transverse clamping block 12 is released under the reverse drive of the motor 9, and the compression plate 6 is moved upward and reset under the drive of the telescopic air pump 4. The operator takes out the processed pipe, and the device can enter the next processing cycle. The whole process realizes the integrated processing of positioning, clamping, drilling, cutting and bending through the coordinated action of the mechanical structure. There is no need for manual transfer of pipes, which improves processing efficiency and product consistency.
