Description

Technical Field

[0001] The utility model belongs to the technical field of compressors, and in particular relates to a compressor valve plate fixing mechanism. Background Art

[0002] The compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. The compressor valve plate is a key component that connects the suction and exhaust valves of the compressor, and has an important impact on the refrigeration effect and noise coefficient of the compressor.

[0003] During the processing of the compressor valve plate, it is necessary to fix the compressor valve plate through a fixing tool to facilitate the processing of the compressor valve plate. However, the fixing and processing in the prior art are two different processes. It is necessary to fix it first and then process it. When it is necessary to process different positions of the valve plate, the valve plate needs to be fixed, then disassembled to move the valve plate, and then fixed again. The operation is cumbersome and the processing efficiency is low. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0026] Example 1

[0027] like Figure 1 As shown;

[0028] A compressor valve plate fixing mechanism comprises a support 1 and a guide assembly 2 fixed on the top of the support 1.

[0029] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "during the processing of the compressor valve plate, the compressor valve plate needs to be fixed by a fixing tool to facilitate the processing of the compressor valve plate, but the fixing and processing of the prior art are two different processes, which need to be fixed first and then processed. When it is necessary to process different positions of the valve plate, the valve plate needs to be fixed, then disassembled to move the valve plate, and then fixed again. The operation is cumbersome and the processing efficiency is low." Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a fixing component 5 is added on this basis.

[0030] like Figure 1-4 As shown in the figure;

[0031] In combination with the above content, in order to improve the processing efficiency, it also includes a punching assembly 4 arranged at the rear end of the support 1 through the L-shaped support plate 3, and a pair of fixing assemblies 5 fixed on the punching assembly 4;

[0032] The punching assembly 4 includes a cylinder 41 installed on the L-shaped support plate 3 , a piston of the cylinder 41 passes through a displacement plate 42 provided on the L-shaped support plate 3 , and a punching head 43 is provided at the bottom center of the displacement plate 42 .

[0033] In this embodiment: the cylinder 41 pushes the displacement plate 42 to move downward, and the displacement plate 42 pushes the punching head 43 to move downward to cooperate with the blanking hole opened on the top of the support 1 and adapted to the punching head 43 to perform a punching operation on the valve plate.

[0034] In an optional embodiment, the two fixing components 5 have the same size and structure, and are symmetrically arranged on the left and right. The fixing component 5 includes a pair of sliding holes 51 opened on the displacement plate 42, and a sliding rod 52 is arranged inside the sliding hole 51. A limiting disk 53 is fixed on the top of the sliding rod 52, and a pressure plate 54 is fixed between the bottom ends of the two sliding rods 52. A spring 55 is sleeved on the sliding rod 52 at the top of the pressure plate 54. The sliding hole 51 matches the sliding rod 52, and the sliding rod 52 slides up and down inside the sliding hole 51. The top of the sliding rod 52 is limited by the limiting disk 53, and the bottom of the sliding rod 52 is limited by the pressure plate 54.

[0035] In this embodiment: the displacement plate 42 moves downward and pushes the pressure plate 54 to follow the movement through the slide rod 52. When the pressure plate 54 is in contact with the valve plate, the pressure plate 54 pushes the slide rod 52 to slide inside the slide hole 51 and compresses the spring 55. The reaction force of the spring 55 pushes the pressure plate 54 to fix the valve plate.

[0036] In an optional embodiment, the guide assembly 2 includes four slide cylinders 21 arranged on the support 1 and four slide columns 22 fixed on the bottom of the displacement plate 42. The slide cylinders 21 match the slide columns 22, and the slide columns 22 slide up and down inside the slide cylinders 21.

[0037] Working principle of this utility model:

[0038] The cylinder 41 pushes the displacement plate 42 to move downward, and the displacement plate 42 moves downward and pushes the pressure plate 54 to follow the movement through the slide rod 52. When the pressure plate 54 is in contact with the valve plate, the pressure plate 54 pushes the slide rod 52 to slide inside the slide hole 51 and compresses the spring 55. The reaction force of the spring 55 pushes the pressure plate 54 to fix the valve plate. The cylinder 41 continues to move, pushing the punching head 43 to move downward and cooperate with the blanking hole opened on the top of the support 1 to punch the valve plate. The valve plate can be fixed during the punching process, and the process is simple, easy to use, and has high processing efficiency.
