Description

Technical Field

[0001] This utility model relates to the field of refrigerant sleeve flaring technology, specifically to a refrigerant sleeve flaring device for automotive air conditioning. Background Technology

[0002] A refrigerant pipe flaring device for automotive air conditioning is a key tool in the installation and maintenance of automotive air conditioning systems. Its design aims to improve flaring accuracy and efficiency, ensuring the sealing and durability of refrigerant piping. Precise control of the stamping process is achieved through a synchronous pulley and position sensor. The double-layer flaring structure includes an inner and outer pipe. The inner pipe is axially connected to a guide rod and a pressure-bearing punch, while a core plate is installed on the inner wall of the outer pipe to enhance structural stability, ensuring uniform force distribution at both ends of the pipe during flaring, reducing wear and noise. A water-based lubrication device evenly sprays lubricant onto the punch surface through an injection rod, reducing the coefficient of friction and preventing cracks on the pipe surface. Furthermore, the device is equipped with a pressing mechanism, utilizing a linkage mechanism and a telescopic cylinder to achieve smooth transmission of the flaring punch. The combination of a positioning block and a flaring die further improves processing accuracy. This device is suitable for high-pressure refrigerant systems such as R410A and can efficiently complete the flaring operations of automotive air conditioning condenser inlet / outlet pipes and evaporator connecting pipes, significantly improving installation efficiency and system reliability.

[0003] The prior art patent document CN216175994U provides a flaring device for building metal pipe sleeves. This device is suitable for building metal pipes with relatively large diameters and thin walls. It has a simple structure, low cost, and convenient operation. It uses two flaring mold columns. The smaller diameter mold column can play a role in pre-flaring. When flaring some high-quality metal pipes, pre-flaring is not required, and both can be processed directly, which improves the flaring speed. The flaring mold columns can be replaced according to the diameter of the metal pipe, and it is suitable for various types of metal pipes.

[0004] If the existing automotive air conditioning refrigerant pipe flaring device does not have a buffer structure designed for the flaring rod, the refrigerant pipe port is prone to cracks or excessive deformation under high pressure impact, affecting the sealing performance. At the same time, without bolt fixation, the pipe body is prone to axial displacement or radial vibration during the flaring process, causing deviation in the flaring size and leading to the risk of refrigerant leakage. Such design defects will reduce assembly accuracy and pipe service life, and increase later maintenance costs. Summary of the Invention

[0005] The purpose of this utility model is to provide an flaring device for automotive air conditioning refrigerant sleeves to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flaring device for automotive air conditioning refrigerant sleeves, comprising a leg support, a support plate fixedly connected to the top of the leg support, a movable component disposed on the top of the support plate, a flaring component disposed on the top of the support plate, the movable component comprising a base, the base being fixedly fixed to the top of the support plate, a motor fixedly connected to the top of the base, a screw fixedly connected to the output end of the motor via a coupling, a sleeve threadedly connected to the outer wall of the screw, a movable plate fixedly connected to one end of the sleeve, a sliding rod movably connected inside the movable plate, and a fixed seat fixedly connected to the top of the support plate.

[0009] Preferably, the flaring assembly includes a shock-absorbing box, which is disposed on the top of the movable plate. A spring is fixedly connected to the inner wall of the shock-absorbing box, and a support rod is fixedly connected to the inner wall of the shock-absorbing box. A push rod is movably connected to the outer wall of the support rod. A shock-absorbing plate is fixedly connected to the top of the push rod. A flaring rod is fixedly connected to one side of the shock-absorbing plate. A support base is fixedly connected to the top of the support plate. A fixing block is fixedly connected to the top of the support base. A fixing sleeve is provided on one side of the fixing block. A threaded hole is opened on one side of the fixing sleeve. A bolt is threadedly connected to the inner wall of the threaded hole. A fixing plate is movably connected to one end of the bolt. A refrigerant pipe is movably connected to the inside of the fixing block.

[0010] Preferably, the shock absorber box forms a movable structure through a support rod and a push rod, with one end of the support rod fixedly connected to the inner wall of the shock absorber box, and the outer wall of the support rod slidably connected to the inner wall of the push rod.

[0013] Compared with the prior art, the beneficial effect of this utility model is: a flaring device for automotive air conditioning refrigerant sleeve.

[0014] (1) When in use, slide the refrigerant pipe from one side of the fixing block until it is flush with the fixing sleeve. The positioning is accurate and no complicated calibration is required. Then rotate the bolt and use the fixing plate to apply stable pressure to the refrigerant pipe to achieve reliable fixing. This design not only simplifies the installation process and saves time and manpower, but also ensures that the refrigerant pipe is firmly connected, effectively avoiding problems such as loosening and leakage, and ensuring the stable operation of the device. (2) This design uses a motor to drive a screw, which in turn drives a sleeve and a moving plate, thereby moving the flaring rod to enlarge the refrigerant pipe opening. The operation is precise and efficient. During the flaring process, the flaring rod squeezes the damping plate, pushes the push rod to slide on the outer wall of the support rod and compresses the spring. The elasticity of the spring effectively reduces the impact force on the refrigerant pipe and equipment during flaring, avoids pipe damage and equipment failure, extends the service life of the equipment and refrigerant pipe, and improves working stability and safety.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model embodiment provides a device for flaring up an automotive air conditioning refrigerant sleeve, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the system includes a leg frame 1, a support plate 2 fixedly connected to the top of the leg frame 1, a movable component 3 and a flared component 4 on the top of the support plate 2, the movable component 3 including a base 301 fixedly attached to the top of the support plate 2, a motor 302 fixedly connected to the top of the base 301, a screw 303 fixedly connected to the output end of the motor 302 via a coupling, a sleeve 304 threadedly connected to the outer wall of the screw 303, a movable plate 305 fixedly connected to one end of the sleeve 304, a sliding rod 306 movably connected inside the movable plate 305, and a fixed seat 307 fixedly connected to the top of the support plate 2. When the motor 302 is started, it drives the screw 303 to rotate, causing the screw 303 to move, and the sleeve 304 to move, thus moving the sleeve 304. The movable plate 305 is moved, and when the movable plate 305 moves, it slides on the outer wall of the slide rod 306. At this time, the shock-absorbing box 401 at the top is moved. When the shock-absorbing box 401 moves, it drives the flaring rod 406 to move. When the flaring rod 406 moves, it widens the opening of the refrigerant pipe 413. After the flaring rod 406 widens the opening of the refrigerant pipe 413, it can squeeze the shock-absorbing plate 405. When the flaring rod 406 squeezes the shock-absorbing plate 405, it can drive the push rod 404 to slide on the outer wall of the support rod 403. When the push rod 404 slides on the outer wall of the support rod 403, it can squeeze the spring 402, thereby achieving the buffering effect of the flaring rod 406 after widening the opening of the refrigerant pipe 413.

[0019] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, the motor 302 forms a threaded structure with the sleeve 304 via the screw 303, and the outer diameter of the screw 303 matches the inner diameter of the sleeve 304. The outer wall of the screw 303 is fitted to the inner wall of the sleeve 304. With the screw 303, when the motor 302 drives the screw 303 to rotate, the screw 303 can rotate on the inner wall of the sleeve 304.

[0020] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, the fixed base 307 and the movable plate 305 form a sliding structure through the slide rod 306. One end of the slide rod 306 is fixedly connected to the inner wall of the fixed base 307, and the outer wall of the slide rod 306 is movably connected to the inside of the movable plate 305. Through the slide rod 306, when the sleeve 304 drives the movable plate 305 to move, the movable plate 305 can slide on the outer wall of the slide rod 306.

[0021] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the flaring assembly 4 includes a shock-absorbing box 401, which is mounted on top of the movable plate 305. A spring 402 is fixedly connected to the inner wall of the shock-absorbing box 401, and a support rod 403 is fixedly connected to the inner wall of the shock-absorbing box 401. A push rod 404 is movably connected to the outer wall of the support rod 403. A shock-absorbing plate 405 is fixedly connected to the top of the push rod 404, and a flaring rod 406 is fixedly connected to one side of the shock-absorbing plate 405. A support base 407 is fixedly connected to the top of the support plate 2, and a fixing block 408 is fixedly connected to the top of the support base 407. A fixing sleeve 409 is provided on one side of the fixing block 408. A threaded hole 410 is provided on one side of the fixed sleeve 409. A bolt 411 is threadedly connected to the inner wall of the threaded hole 410. A fixing plate 412 is fixedly connected to one end of the bolt 411. A refrigerant pipe 413 is movably connected inside the fixing block 408. When using this device, the refrigerant pipe 413 is slid into the interior of the fixing block 408 from one side, so that the refrigerant pipe 413 enters the fixed sleeve 409 and is flush with the fixed sleeve 409. At this time, the bolt 411 is rotated from the inner wall of the threaded hole 410, so that the fixing plate 412 at one end of the bolt 411 fixes the refrigerant pipe 413.

[0022] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, the shock absorber box 401 forms a movable structure with the support rod 403 and the push rod 404. One end of the support rod 403 is fixedly connected to the inner wall of the shock absorber box 401, and the outer wall of the support rod 403 is slidably connected to the inner wall of the push rod 404. With the support rod 403, the push rod 404 can slide on the outer wall of the support rod 403 after being subjected to force, which allows the push rod 404 to compress the spring 402.

[0023] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, the damping plate 405 forms a movable structure with the damping box 401 through the flared rod 406, and one end of the flared rod 406 is fixedly connected to one side of the damping plate 405, and the outer wall of the flared rod 406 is slidably connected to one side of the damping box 401.

[0024] Further, such as Figure 1 , Figure 3 and Figure 4As shown, the fixing sleeve 409 forms a threaded structure with the bolt 411 through the threaded hole 410, and one end of the bolt 411 extends into the threaded hole 410 to fix the fixing plate 412. Through the threaded hole 410, the bolt 411 can rotate on the inner wall of the threaded hole 410, which can push the fixing plate 412 to fix the refrigerant pipe 413.

[0025] Working principle: When using this device, the refrigerant pipe 413 is slid into the interior of the fixing block 408 from one side, so that the refrigerant pipe 413 enters the fixing sleeve 409 and is flush with the fixing sleeve 409. At this time, the bolt 411 is rotated from the inner wall of the threaded hole 410, so that the fixing plate 412 at one end of the bolt 411 fixes the refrigerant pipe 413. At this time, the motor 302 is started, which drives the screw 303 to rotate. When the screw 303 rotates, it drives the sleeve 304 to move. When the sleeve 304 moves, it drives the moving plate 305 to move. When the moving plate 305 moves, it slides on the outer wall of the sliding rod 306. When the device moves, the top shock absorber box 401 can be moved. When the shock absorber box 401 moves, it can move the flaring rod 406. When the flaring rod 406 moves, it can widen the opening of the refrigerant pipe 413. After the flaring rod 406 widens the opening of the refrigerant pipe 413, it can squeeze the shock absorber plate 405. When the flaring rod 406 squeezes the shock absorber plate 405, it can drive the push rod 404 to slide on the outer wall of the support rod 403. When the push rod 404 slides on the outer wall of the support rod 403, it can squeeze the spring 402, thereby achieving the buffering effect of the flaring rod 406 after widening the opening of the refrigerant pipe 413.
