Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a spacing tool for a compressor motor. Background Art

[0002] The compressor is a driven fluid machine that can elevate low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the operation of the motor, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for refrigeration. It is widely used in energy-saving refrigerators, freezers, air conditioners or dehumidifiers. During the installation of the compressor, it is necessary to insert the rotor on the crankshaft of the cylinder seat (the rotor also serves as a sleeve), and then insert the motor punching sheet on the outer rotor and press it. The staff connects the motor punching sheet and the cylinder seat with bolts to install the motor punching sheet. A fixed distance needs to be formed between the rotor and the motor punching sheet. At present, spacers are manually placed outside the rotor, and then the motor punching sheet is inserted into the rotor. However, the manually placed spacers are not only unevenly distributed, but also easy to fall off. Summary of the invention

[0004] The utility model provides a spacer fixture for a compressor motor, comprising a stop column 1 with a through hole 2 in the middle, the stop column 1 consisting of an upper step column and a lower step column, the upper end of the upper step column is provided with a fixed beveled ring 3, the upper step column is slidably provided with a movable beveled ring 4 which can be moved up and down, the upper end of the fixed beveled ring 3 and the lower end of the movable beveled ring 4 are provided with symmetrical inclined annular surfaces, and the outer ring of the lower step column is evenly distributed with spacer sheets 5 inclined from the inner upper to the outer lower along its axis.

[0005] Furthermore, an installation bevel ring is coaxially arranged at the upper end of the lower step column, and the outer ring of the installation bevel ring is uniformly provided with inclined grooves 1.1 for accommodating the installation of the spacer 5 along the axis of the lower step column.

[0006] Furthermore, the spacer 5 is riveted to the inclined groove 1 . 1 by means of rivets 6 , and the depth of the inclined groove 1 . 1 is greater than the thickness of the spacer 5 .

[0008] Furthermore, the spacer 5 is in the shape of a long strip.

[0009] Furthermore, the number of the spacers 5 is greater than or equal to 6 and less than or equal to 10.

[0010] The advantages of the utility model are: after the through hole penetrates the crankshaft, the abutment column abuts against the upper end surface of the rotor, thereby positioning the spacer tooling, and the spacers are evenly distributed outside the rotor and will not fall off; the spacers inclined from the inside to the outside are evenly distributed on the outer ring of the lower step column and are evenly distributed; the fixed bevel ring and the movable bevel ring have the same structure, and automatic lowering and lifting are achieved through the fixed bevel ring and the movable bevel ring; it is convenient to take and put through the fixed bevel ring; the inclined groove is formed during processing, which is convenient for positioning the spacers, thereby facilitating the installation of the spacers; the rivets are suitable for thin-wall connections, can ensure the stability of the structure, and are easy to install and will not fall off after long-term use.

[0015] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0016] See also Figures 1 to 4 The utility model provides a spacer fixture for a compressor motor, which includes a resisting column 1 with a through hole 2 in the middle. After the through hole penetrates into the crankshaft of the compressor, the resisting column resists against the upper end surface of the rotor, thereby positioning the spacer fixture. The resisting column 1 is composed of an upper step column and a lower step column. A fixed bevel ring 3 is arranged at the upper end of the upper step column. The fixed bevel ring and the resisting column are an integrated structure. A movable bevel ring 4 is slidably provided on the upper step column so as to move up and down. Automatic lowering and lifting are realized by the fixed bevel ring and the movable bevel ring. Moreover, it is convenient to take and place by the fixed bevel ring. The upper end of the fixed bevel ring 3 and the lower end of the movable bevel ring 4 are provided with symmetrical inclined annular surfaces. The outer ring of the lower step column is evenly distributed with spacers 5 inclined from the inner upper to the outer lower along its axis. The spacers 5 are in the shape of long strips. After the through hole passes through the crankshaft of the compressor, the abutment column abuts against the upper end surface of the rotor, thereby positioning the spacer fixture. At this time, the spacers are distributed around the rotor. The staff inserts the motor punching into the spacer fixture and presses it tightly to form a gap between the motor punching and the rotor. After the motor punching is installed and fixed, the spacer fixture is lifted, and the gap between the motor punching and the rotor is formed.

[0017] The upper end of the lower step column is coaxially provided with an installation bevel ring, and the outer ring of the installation bevel ring is evenly distributed along the axis of the lower step column with inclined grooves 1.1 for installing the spacer 5. The inclined grooves are formed during processing to facilitate positioning of the spacer, thereby facilitating the installation of the spacer.

[0018] The spacer 5 is riveted to the inclined groove 1.1 by rivets 6, and the depth of the inclined groove 1.1 is greater than the thickness of the spacer 5. Rivets have reliable connection, are suitable for thin-wall connection, can ensure the stability of the structure, are easy to install, and will not fall off during long-term use.

[0019] The fixed bevel ring 3 and the movable bevel ring 4 have the same structure. The telescopic bevel block used for lifting and lowering descends, and the telescopic bevel block retracts after passing through the fixed bevel ring, and pops out after entering between the fixed bevel ring and the movable bevel ring, and then the telescopic bevel block rises, and the telescopic bevel block lifts the spacing tooling through the fixed bevel ring; the telescopic bevel block carrying the spacing tooling descends, and the spacing tooling abuts against the rotor and does not move, and the telescopic bevel block continues to descend and retracts after passing through the movable bevel ring, and pops out after entering between the movable bevel ring and the lower step column, and then the telescopic bevel block rises, and the telescopic bevel block rises together with the movable bevel ring, and after the movable bevel ring and the fixed bevel ring are combined, the telescopic bevel block contracts through the inclined ring surface of the movable bevel ring, and the telescopic bevel block telescopes away from the movable bevel ring and the fixed bevel ring, thereby putting down the spacing tooling.

[0020] The number of the spacers 5 is greater than or equal to 6 and less than or equal to 10. Preferably, the number of the spacers is 8, and the density of the 8 spacers is appropriate relative to the motor punching sheets.

[0021] The utility model discloses a spacer fixture for a compressor motor: after the through hole penetrates the crankshaft, the abutment column abuts against the upper end surface of the rotor, thereby positioning the spacer fixture, and the spacers are evenly distributed outside the rotor and will not fall off.

[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 principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
