Description

Technical Field

[0001] This utility model relates to the field of compressor pipe processing, and in particular to a flaring device for compressor pipe processing. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it by driving a piston through the operation of a motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle. This realizes the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption). Compressors are classified into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc.

[0003] Chinese patent CN217665909U discloses a flaring device for processing compressor pipe fittings, including a base with a concave arc surface on the inner side of the base, a frame fixedly mounted on the base, a pressure plate inside the frame, and two spaced-apart first hydraulic cylinders fixedly mounted on the frame. The output ends of the first hydraulic cylinders are fixedly connected to the pressure plate. A support frame is fixedly mounted at one end of the base, and a frustum is arranged inside the support frame. A second hydraulic cylinder is fixedly mounted on the support frame. The device also includes a drive mechanism. The pipe fitting is placed in the base, and the first hydraulic cylinder drives the pressure plate to move downward and press the pipe fitting. Then, the second hydraulic cylinder drives the frustum to move towards the pipe fitting, thereby flaring the pipe fitting. While the frustum moves into the pipe fitting, a valve on the drain pipe is opened, so that the lubricating fluid inside the cylinder flows onto the surface of the frustum, making the surface of the frustum coated with lubricating fluid. This reduces the friction between the frustum and the pipe fitting, making it easier for the frustum to enter the pipe fitting.

[0004] The aforementioned patent has certain shortcomings in its use. In the aforementioned patent, the lubricating fluid is directly discharged through the drain pipe to lubricate the frustum and reduce friction. However, the aforementioned patent does not have a recycling structure, which leads to the waste of lubricating fluid and increases the operating cost of the device. To address these issues, we propose a flaring device for processing compressor pipe fittings. Summary of the Invention

[0023] Please see Figure 1-5In this utility model, a flaring device for processing compressor pipe fittings includes a base plate 1. An oil tank 8 is connected to the upper surface of the base plate 1. A first oil pump 9 is connected to the inner bottom wall of the oil tank 8. The output end of the first oil pump 9 is connected to a rigid adjustable oil pipe 10. The top end of the rigid adjustable oil pipe 10 passes through the oil tank 8 and is connected to a nozzle 11. A collection box 12 is connected to the bottom surface of the base plate 1. A filter screen 13 is connected inside the collection box 12. A second oil pump 14 is connected to the bottom surface of the base plate 1. An extraction pipe 15 is connected to the input end of the second oil pump 14. The top end of the extraction pipe 15 passes through the collection box 12 and extends into the collection box 12. The output end of the second oil pump 14 is connected to a delivery pipe 16. The top end of the delivery pipe 16 passes through the oil tank 8 and extends into the oil tank 8. Specifically, the upper surface of the base plate 1 has an arc so that the lubricating fluid can flow effectively into the collection box 12.

[0024] A support assembly 2 is connected to the bottom surface of the base plate 1. The support assembly 2 includes multiple support legs 201, and a base 202 is connected to the bottom surface of each support leg 201. Through the cooperation of the support legs 201 and the base 202, the device can be effectively supported, preventing it from shaking during use and increasing its stability. A hole-expanding assembly 3 is connected to the upper surface of the base plate 1. The hole-expanding assembly 3 includes a support plate 301. A first motor 302 is connected to the outer surface of the support plate 301. A rotating column 304 is connected to the output end of the first motor 302. A first bearing 303 is embedded in the outer surface of the support plate 301. The inner ring of the first bearing 303 is connected to the outer surface of the rotating column 304. A mounting plate 305 is connected to the top of the rotating column 304. A hole-expanding block 306 is connected to the outer surface of the mounting plate 305. The first motor 302 drives the rotating column 304 to rotate using the first bearing 303, thereby causing the mounting plate 305 to drive the hole-expanding block 306 to rotate. This can effectively expand the hole of the pipe fitting, increasing the convenience and flexibility of use.

[0025] An adjusting assembly 4 is connected to the outer surface of the base plate 1. The adjusting assembly 4 includes a second motor 401 and two second bearings 402, both of which are located inside the base plate 1. The output end of the second motor 401 is connected to a threaded rod 403. The inner rings of the two second bearings 402 are connected to the outer surface of the threaded rod 403. A nut 404 is threadedly connected to the outer surface of the threaded rod 403. An adjusting plate 405 is connected to the upper surface of the nut 404. The second motor 401 drives the threaded rod 403 to rotate via the second bearings 402, thereby causing the nut 404 to move the adjusting plate 405. The internal connection includes a clamping assembly 5, which includes two electric push rods 501. The output ends of the two electric push rods 501 are connected to clamping plates 502. By activating the electric push rods 501, the electric push rods 501 drive the clamping plates 502 to move, thereby clamping the pipe fitting. With the cooperation of the adjusting assembly 4 and the clamping assembly 5, the clamping force can be automatically adjusted according to the size of the pipe fitting, supporting the rapid change of various specifications of pipe fittings without repeated manual adjustments, significantly improving production efficiency. At the same time, it achieves more accurate automatic alignment between the pipe fitting and the reaming assembly 3, avoiding the problem of reaming failure caused by manual alignment deviation.

[0026] Mounting plate 305 has a mounting assembly 17 on its outer surface. The mounting assembly 17 includes multiple threaded holes 1701, and each threaded hole 1701 has a fastening bolt 1702 threadedly connected to its inner wall. By using the fastening bolt 1702 and the threaded hole 1701 together, different sizes of reaming blocks 306 can be quickly replaced to meet the diverse needs of flaring diameter and shape, improving the applicability of the device and facilitating its long-term use. The base plate 1 has two sliding grooves 6 inside, and the inner walls of the two sliding grooves 6 are slidably connected to sliders 7. The sides of the two sliders 7 that are close to each other are connected to the outer surface of the nut 404. By sliding the sliders 7 on the inner walls of the sliding grooves 6, the nut 404 can be effectively adjusted, increasing the stability of the nut 404 adjustment. At the same time, the nut 404 can be limited to prevent it from rotating during adjustment, which could damage the device, increasing its service life and reducing its maintenance costs.

[0027] The working principle of this utility model is as follows: In use, the pipe fitting is placed between the two clamping plates 502, and the electric push rod 501 is activated to clamp the pipe fitting with the clamping plates 502. Then, the first motor 302 is activated, driving the rotating column 304 to rotate via the first bearing 303. This causes the mounting plate 305 to rotate the expanding block 306 on the outer surface of the rotating column 304. Next, the first oil pump 9 is activated to extract lubricating fluid from the oil tank 8, which is then transported to the nozzle 11 via the rigid adjustable oil pipe 10. The reaming block 306 is lubricated, and the second motor 401 is started to make the threaded rod 403 rotate using the second bearing 402. This causes the nut 404 to drive the adjusting plate 405 to move under the cooperation of the slide groove 6 and the slider 7. In turn, the adjusting plate 405 drives the pipe to move towards the reaming assembly 3 to achieve the purpose of reaming. After the reaming is completed, the second oil pump 14 is started to extract the lubricating fluid inside the collection box 12 through the extraction pipe 15. The extracted lubricating fluid is then returned to the oil tank 8 through the delivery pipe 16.
