[0002] As the core component of refrigerator refrigeration, the compressor sucks in low-temperature and low-pressure refrigerant gas from the intake pipe, compresses it by driving the piston through the motor, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle. During the production and processing of the compressor exhaust pipe, a special clamp is required to clamp and fix the compressor exhaust pipe to facilitate welding of the compressor exhaust pipe.

[0003] After searching, the authorization announcement number CN210046258U and the authorization announcement date 2020.02.11 discloses a positioning fixture for welding the exhaust pipe of a compressor, including an installation frame, a sliding frame and a sliding plate. The four corners of the installation frame are fixed with fixing ears, and the four fixing ears are rotatably connected to the outer walls at both ends of the two first screws, and the outer walls of the two first screws are threadedly connected to the inner walls of the two screw rings, respectively. The inner walls on both sides of the installation frame are provided with strip through holes, and the inner walls of the two strip through holes are slidably connected to the two ends of the sliding frame through connecting rods, and one end of the two connecting rods is fixedly connected to one side of the two screw rings, and the inner walls on both sides of the sliding frame are provided with sliding grooves. The utility model is a positioning fixture for welding the exhaust pipe of a compressor. The device fixes the exhaust pipe inside the sliding plate, and can be adjusted inside the installation frame through the sliding plate. The use position of the exhaust pipe can be adjusted according to the use requirements, making the device more convenient to use.

[0004] The prior art can drive the sliding frame to move by operating the first screw rod to adjust the height of the exhaust pipe. However, in actual use, the angle of the exhaust pipe cannot be adjusted, which is inconvenient to use. At the same time, the prior art requires the operation of two second screw rods to clamp and fix the exhaust pipe, which is inconvenient to operate. In addition, the prior art generates harmful gases during welding that float into the air and cause pollution to the environment. For this reason, we provide a special fixture for exhaust pipe processing to solve the above problems. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] For specific embodiment 1, please refer to Figure 1-3The utility model is a special fixture for exhaust pipe processing, including an angle adjustment component 1, which includes a mounting plate 101. A rotating plate 102 is arranged in front of the lower side of the mounting plate 101. The rotating plate 102 is arranged in a circular shape. A mounting sleeve 1022 is fixed at the middle position of the rear wall of the rotating plate 102. A bearing is fixed inside the mounting sleeve 1022. A fixing rod 1015 is fixed inside the bearing. The fixing rod 1015 is fixedly connected to the mounting plate 101. An angle scale ring 1012 is fixed on the outside of the rotating plate 102 corresponding to the front wall of the mounting plate 101. The exhaust pipe can be rotated to achieve angle adjustment by rotating the rotating plate 102.

[0032] Specifically, a universal ball 1014 is fixed in a circular array on the inner side of the angle scale ring 1012 corresponding to the front wall of the mounting plate 101, and the ball in the universal ball 1014 is in contact with the rotating plate 102. The setting of the universal ball 1014 can provide support for the rotating plate 102 to prevent the rotating plate 102 from tilting. A pointer 1021 is fixed on the outer peripheral wall of the rotating plate 102, and the pointer 1021 is used to check the scale on the angle scale ring 1012.

[0033] A screw rod 103 is threadedly connected along the edge of the rotating plate 102, and countersunk holes 1013 are provided in a circular array on the front wall of the mounting plate 101 at the position where the screw rod 103 is located, and the rear end of the screw rod 103 is located inside the countersunk hole 1013 to prevent relative movement between the screw rod 103 and the mounting plate 101. After the angle is adjusted, the rear end of the screw rod 103 is located in the corresponding countersunk hole 1013 to prevent the rotating plate 102 from rotating.

[0034] A screw block 1031 is fixed to the front end of the screw rod 103. The screw rod 103 can be rotated by operating the screw block 1031. The outer wall of the screw block 1031 is provided with anti-slip grooves to increase the friction when operating the screw block 1031. Bolts 1011 are provided at the four corners of the mounting plate 101, and the mounting plate 101 can be fixed on the mounting platform by the bolts 1011.

[0035] The operation process of this embodiment is: when adjusting the angle, the screw block 1031 is operated to rotate, thereby driving the screw rod 103 to rotate, so that the rear end of the screw rod 103 is disengaged from the countersunk hole 1013. At this time, the rotating plate 102 is operated to rotate, driving the pointer 1021 to rotate. With the cooperation of the pointer 1021 and the angle scale ring 1012, the rotating plate 102 is rotated to a suitable angle, and then the screw block 1031 is operated in reverse to rotate, driving the rear end of the screw rod 103 to enter a suitable countersunk hole 1013.

[0036] For specific embodiment 2, please refer to Figure 1 and 4, which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment, but is different from the first embodiment in that: a clamping assembly 2 is arranged in front of the angle adjustment assembly 1, and the clamping assembly 2 includes a threaded rod 201, and the threads of the outer peripheral walls on both sides of the threaded rod 201 are in opposite directions, and anti-slip blocks 204 are symmetrically arranged on the left and right sides behind the threaded rod 201, and the anti-slip blocks 204 can be made of a material with high friction. A side plate 2011 is arranged on the outer side of the anti-slip block 204, and the side plate 2011 is threadedly connected to the threaded rod 201, and the threaded rod 201 is rotated to drive the two side plates 2011 closer to each other, and drive the two anti-slip blocks 204 closer to each other to achieve clamping of the exhaust pipe.

[0037] Specifically, the inner side wall of the anti-sliding plate 204 is provided with a receiving groove 2041, and the receiving groove 2041 is arc-shaped. In the clamping state, the exhaust pipe is located in the receiving groove 2041, and the outer side wall of the anti-sliding plate 204 is fixed with a connecting plate 205, and the outer side wall of the connecting plate 205 is fixed with a connecting rod 2031. The outer end of the connecting rod 2031 is fixed with a moving block 203, and the outer part of the moving block 203 is fixedly connected to the side plate 2011. When the threaded rod 201 rotates, the moving block 203 and the vertical plate 202 move relative to each other.

[0038] A vertical plate 202 is fixed to the outside of the moving block 203 corresponding to the front wall of the rotating plate 102, and the moving block 203 and the vertical plate 202 are clearance-matched. The threaded rod 201 is rotatably connected to the vertical plate 202 through a bearing, so that the threaded rod 201 is transmitted at a fixed position. A boss 2012 is fixed to the right end of the threaded rod 201, and the outer peripheral wall of the boss 2012 is provided with anti-slip grooves to increase friction during operation.

[0039] The rest of the structure is the same as that of the first embodiment.
