[0002] The compressor is a driven fluid machine that can lift low-pressure gas into 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 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 crankshaft into the cylinder seat, and then put the hot-baked sleeve on the crankshaft. After the hot-baked sleeve cools down, the crankshaft and sleeve are fixed. At present, there is no corresponding tooling to position the cylinder seat and crankshaft so that the crankshaft can pass through the cylinder seat when the sleeve is assembled.

[0017] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0018] See also Figures 1 to 6The utility model provides a compressor shaft sleeve assembly tool, which is a part of the shaft sleeve assembly device, and includes a base plate 1. The shaft sleeve assembly device includes two stabilizing plates 10 that are symmetrically arranged in front and back and are concave. The inner sides of the stabilizing plates 10 are rotatably provided with a conveying chain 12. The stabilizing plates are rotatably provided with a chain shaft connected to the conveying chain. The lower right side of the stabilizing plate is rotatably provided with a rotating shaft driven by a stepping motor 11. The two chain shafts on the lower right are connected to the rotating shaft through a conveyor belt. The tool is equidistantly installed on the two conveying chains 12 through the base plate. There are 4 toolings on the upper and lower sides. The tooling on the upper right side The tooling on the left side of the loading position is the crankshaft top and sleeve installation position, the tooling on the upper left side is the unloading position, and the tooling on the right side of the unloading position is the cooling position. A support rail 13 for supporting the upper conveying chain 12 is horizontally arranged between the grooves of the stabilizing block 10, and a cylinder 14 for lifting the lifting plate is arranged upward on the upper ends of the two stabilizing blocks 10. Two frame bars 15 symmetrically arranged on the front and rear sides of the cylinder 14 are arranged on the left side of the cylinder 14. A front positioning cylinder 2 and a rear positioning cylinder 3 for positioning the cylinder seat are respectively arranged on the front and rear sides of the upper end of the base plate 1, and an avoidance groove 1.1 is opened at the right end of the base plate 1. The avoidance groove is set to avoid the crankshaft that is pushed up. A side support plate 4 is vertically set at the left end of the base plate 1. Slide rods 6 are vertically set on the front and rear sides of the lower end of the base plate 1. A horizontally set lifting plate 7 is slidably provided at the slide rod 6. A crankshaft positioning assembly 8 for positioning the crankshaft is set at the upper end of the lifting plate 7. A limiting column in contact with the lifting plate 7 is set at the bottom of the slide rod 6. Guide columns 9 are longitudinally set on the front and rear sides of the lifting plate 7. The staff places the cylinder seat on the front positioning cylinder and the rear positioning cylinder and leans against the side support plate to position the cylinder seat, and then places the crankshaft on the crankshaft positioning assembly. The stepper motor drives the conveyor chain to convey the loaded tooling to the top of the cylinder. The cylinder lifts the lifting plate for a section, and the lifting plate and the crankshaft positioning assembly carry the front end shaft of the crankshaft through the cylinder seat. The staff inserts the spacer between the crankshaft and the cylinder seat, and the cylinder pushes the lifting plate to the bottom along the sliding rod. The spacer is stuck by the crankshaft and the cylinder seat, and the hot-baked sleeve is inserted into the front end shaft of the crankshaft by a robot or manually. Then the stepper motor drives the conveyor chain to transmit the same distance, and the assembled tooling reaches the cooling position. The guide column is translated to the rack bar and placed on the rack bar so that the crankshaft and the lifting plate will not fall and remain stable (at this time, the hot-baked sleeve has not cooled and is not firmly locked). During this process, the cylinder is reset, and the hot-baked sleeve has a cooling process when the next tooling is assembled. The cooled sleeve firmly locks the crankshaft. Then the stepper motor drives the conveyor chain to transmit the same distance, and the assembled tooling reaches the unloading position. The staff pulls out the spacer and removes the assembled cylinder seat.

[0019] The top end of the side support plate 4 is hinged with a pressing block 5, and a torsion spring is provided at the hinge of the side support plate 4 and the pressing block 5. The cylinder seat can be pressed by the pressing block to prevent the cylinder seat from being lifted up when the front end shaft of the crankshaft is passed.

[0020] The pressing portion is provided to facilitate the staff to loosen the cylinder seat, and the pressing block 5 extends horizontally to the left to form the pressing portion.

[0021] See also Figure 1 The crankshaft positioning assembly 8 includes a fixing block 8.1 fixed vertically to the upper end of the lifting plate 7, and side limit blocks 8.2 are symmetrically arranged on the front and rear side walls of the fixing block 8.1, and a positioning hole 8.3 is opened at the top of the fixing block 8.1. The positioning hole allows the rear end shaft of the crankshaft to be inserted, the crank of the crankshaft fits on the upper end surface of the fixing block, and the side surface of the crank of the crankshaft fits on the side limit blocks, thereby positioning the crankshaft.

[0022] The right side of the upper end of the side limit block 8.2 is provided with a rounded corner. The rounded corner is provided with a crank that guides the crankshaft to abut against the side limit block.

[0023] 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.
