Novel compressor rotor blade groove machining clamping tool

Abstract

The invention discloses a novel compressor rotor blade groove machining clamping tool which comprises a clamping device. The clamping device comprises a base, two clamping blocks are arranged on the base, and the two clamping blocks are arranged in a direct facing mode, and clamping sliding plate mounting seats are arranged on the opposite side faces of the clamping blocks respectively. The clamping sliding plate mounting seats are provided with a first guide sliding groove and a second guide sliding groove respectively, the upper end of the first guide sliding groove and the upper end of the second guide sliding groove are inclined inwards, and clamping sliding plates are arranged in the first guide sliding groove and the second guide sliding groove respectively. Connecting columns are arranged at the upper ends of the clamping sliding plates respectively, and the upper ends of the connecting columns are hinged to the two ends of a transmission cross rod respectively. An air cylinder or oil cylinder is arranged on one side of the clamping device, and a transmission lever is arranged between the air cylinder or oil cylinder and the clamping device. One end of the transmission lever is connected with the middle of the transmission cross rod, and the other end of the transmission lever is hinged to the telescopic end of a piston rod of the air cylinder or oil cylinder. The air cylinder or oil cylinder is utilized for driving the clamping sliding plates to vertically move in the guide sliding grooves, and semi-automatic control over rotor clamping is achieved.

Description

technical field [0001] The invention relates to the field of machining fixtures, in particular to a novel compressor rotor blade slot machining and clamping fixture. Background technique [0002] The compressor is a driven fluid machine that upgrades 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, drives the piston through the motor to compress it, and sends it to the compressor. The exhaust pipe discharges high-temperature and high-pressure refrigerant gas to provide power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression→condensation (heat release)→expansion→evaporation (heat absorption), and the rotor of the compressor core is the work of the entire compressor The core component of the rotor blade groove is traditionally processed by manual clamping. Manual clamping is not only time-consuming and labor-intensive, but more...

[0002] The compressor is a driven fluid machine that elevates 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, and drives the piston to compress it through the operation of the motor. The exhaust pipe discharges high-temperature and high-pressure refrigerant gas to provide power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression→condensation (heat release)→expansion→evaporation (heat absorption), and the rotor of the compressor core is the work of the entire compressor The core component of the rotor blade groove is traditionally processed by manual clamping. Manual clamping is not only time-consuming and labor-intensive, but more importantly, the clamping reliability is seriously affected by the operator's business ability, and once the rotor is processed, the clamping reliability is not enough. Not only affects the pass rate of the product, but also may endanger the life safety of the operator
