Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a grinding device for a compressor cylinder seat. Background Art

[0002] A compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas and is the heart of the refrigeration system. It draws in low-temperature, low-pressure refrigerant gas from the intake pipe, compresses it through the piston driven by the motor, and then discharges high-temperature, high-pressure refrigerant gas into the exhaust pipe, providing power for refrigeration. It is widely used in energy-saving refrigerators, freezers, air conditioners, and dehumidifiers. The cylinder base is a key component of the compressor. After the cylinder base is formed, it needs to be drilled and polished. This polishing process requires smoothing the three corners of the cylinder base to ensure a flat end surface. Manual polishing is not only time-consuming and labor-intensive, but also difficult to ensure the smoothness of the polishing, thus affecting product quality. Summary of the Invention

[0015] The present invention will be described in detail below with reference to the accompanying drawings.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] See Figures 1 to 4The utility model provides a grinding device for a compressor cylinder seat, which includes a base 1, a flat plate 2 is elastically slidably provided above the base 1, sliding columns 9 for sliding the flat plate 2 up and down are vertically arranged around the base 1, and an elastic member 10 is provided on the outer sleeve of the sliding column 9 for connecting the sliding column 9 and the flat plate 2. A grinding wheel 5 driven by a motor 4 and located below the flat plate 2 is horizontally arranged above the base 1, and a groove for accommodating the movement of the crankshaft seat of the cylinder seat is provided in the middle of the grinding wheel. A positioning hole 2.1 is provided at the upper end of the flat plate 2, and a support column 3 is vertically provided at the top of the flat plate 2. A bracket 6 is provided on the left side of the upper end of the base 1, and a cylinder 7 for pressing down the cylinder seat is provided downward at the top of the bracket 6. Align the crankshaft seat and the three corners of the cylinder seat with the positioning holes and place them so that the flat bottom of the cylinder seat rests horizontally against the support column, thereby positioning the cylinder seat and keeping the three corners of the cylinder seat vertical. Then the cylinder presses down the cylinder seat, and the cylinder seat and the flat plate descend vertically along the sliding column. The three corners of the cylinder seat are polished flat after contacting the grinding wheel driven by the motor.

[0018] The support columns 3 correspond to the three flat bottoms of the cylinder base. The two support columns 3 on the left are arranged symmetrically, with the right support column 3 lower than the left support column 3. The support columns are flat against the three flat bottoms of the cylinder base, which correspond to the three corners of the cylinder base. The two flat bottoms on the left are flush, and the flat bottom on the right is lower than the two flat bottoms on the left. This keeps the three corners of the cylinder base vertical, allowing the grinding wheel to polish the three corners of the cylinder base evenly, making the end surfaces of the three corners of the cylinder base flush and neat.

[0019] The support 6 is composed of a lower column connected to an upper crossbar, and a reinforcing rib is connected between the column and the crossbar. The cylinder is downwardly arranged on the top of the crossbar to strengthen the connection strength of the column and the crossbar.

[0020] The piston rod end of the cylinder 7 is connected to a pressure plate 8. The pressure plate presses down the annular projection in the middle of the cylinder seat, and the upper end surface of the annular projection is a horizontal plane.

[0021] See Figure 3 、 Figure 4 The middle and top ends of the sliding column 9 are respectively provided with a limit ring and a limit column, and the elastic member 10 connects the limit ring and the plate 2. The limit column setting can make the upper plate abut against the limit ring, and the limit ring supports the elastic member so that the plate is elastically pressed against the limit column.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
