Clamping tool

Abstract

The invention discloses a clamping tool which comprises a base. Two clamping blocks are arranged on the base and arranged in a direct facing mode, and clamping sliding plate mounting seats are fixed to the opposite side faces of the two clamping blocks respectively. The clamping sliding plate mounting seats are provided with a first guide sliding groove and a second guide sliding groove respectively, clamping sliding plates are arranged in the first guide sliding groove and the second guide sliding groove respectively, and the first guide sliding groove and the second guide sliding groove are both chutes with the upper ends inclined inwards. The clamping tool has the beneficial effects that when the clamping sliding plates move upwards in the guide sliding grooves, a rotor can be clamped, and machining is facilitated; when the clamping sliding plates move downwards in the guide sliding grooves, the rotor can be loosened, and machining faces can be conveniently switched; therefore, the action that when the machining faces are repeatedly switched due to machining needs, a whole clamping device is removed repeatedly, and after the machining faces are adjusted, mounting and clamping are repeated is avoided; machining efficiency can be improved, the labor intensity of workers can be lowered, and meanwhile the clamping reliability of the whole clamping tool is improved.

Description

technical field [0001] The invention relates to the field of machining fixtures, in particular to a 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, the traditional clamping tool for processing the blade groove of the rotor generally adjusts the relative position of the entire clamping tool and then puts the rotor...

[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, the traditional clamping tool for processing the blade groove of the rotor generally adjusts the relative position of the entire clamping tool and then puts the rotor into the fixture, and then pushes the fixtures close to each other through other auxiliary tools so that the rotor is clamped. In this operation, once a certain surface is processed and the processing surface of the rotor needs to be adjusted, the entire clamping device must be removed to adjust the processing surface and then reinstall and clamp. This operation method is not only time-consuming and laborious, but more importantly, it is constantly repeated. During the installation and clamping process, the fatigue of the workers will continue to rise, and the clamping reliability will continue to decrease. Once the clamping reliability is not light enough before the rotor is processed, it will affect the pass rate of the product and may endanger the life safety of the operator.
