Embodiment 1

[0039] The preferred embodiment discloses a cylinder block. like Figure 2 to Figure 7 As shown, the cylinder block includes a base 1 and a detachable bearing 2, the base 1 is provided with a bearing hole 11, and the detachable bearing 2 is detachably installed in the bearing hole 11.

[0040] The processing method of the structural cylinder block is basically the same as the existing method, the difference is that the method includes the following steps:

[0041] Step 1. Processing and forming the detachable bearing 2 and the base 1 respectively, and then installing the detachable bearing 2 on the base 1 for semi-finishing. The detachable bearing 2 and the base 1 are integrally installed and processed together to ensure the verticality of the cylinder bore 15 and the shaft hole 24 of the cylinder block.

[0042] Step 2, dismantling the detachable bearing 2 from the base 1, and finishing the cylinder bore 15.

[0043] Step 3. Install the detachable bearing 2 on the base 1 a...

Embodiment 2

[0055] This preferred embodiment discloses a compressor, including various cylinder blocks as described in the first preferred embodiment. The processing of the cylinder seat is more convenient, the force of the whole compressor is more reasonable, and the reliability is higher.

Abstract

The invention discloses a cylinder seat, a compressor and a machining method for the cylinder seat, and belongs to the field of compressors and parts thereof. The compressor is designed for solving the problem that force bearing conditions of existing devices are unreasonable. The cylinder seat comprises a base and a detachable bearing. A bearing hole is formed in the base, and the detachable bearing is detachably installed in the bearing hole. The compressor comprises the cylinder seat. According to the machining method for the cylinder seat, the detachable bearing is detached from the base for finish machining of a cylinder hole. The cylinder seat can shorten the force arm length L1, improve the force bearing conditions of the bearing, and reduce stress concentration. According to the compressor, the force bearing conditions of the bearing are improved, and the reliability of the compressor is improved. According to the machining method for the cylinder seat, the machining process of the cylinder hole is simplified, the force arm length L1 is shortened as much as possible, and the force bearing conditions of the bearing are improved.

Description

technical field [0001] The invention relates to the field of compressors and accessories thereof, in particular to a cylinder block, a compressor provided with the cylinder block, and a processing method for the cylinder block. Background technique [0002] The cylinder block of the traditional refrigerator compressor is an integral structure, and components such as the crankshaft, piston, connecting rod and piston pin are installed in the cylinder block. The force on the compressor is mainly related to the reaction force F1 of the refrigerant, the force F2 on the upper end of the bearing and the force F3 on the lower end of the bearing, and is related to the length of the arm L1 (the distance between F1 and F2) and the length L2 of the arm (the distance between F3 and F2 the distance between them). The shorter the L1 and the longer the L2, the better the stress of the compressor, the better the stress of the bearing, and the greater the reliability of the compressor. [0...
