Special film chuck for disc parts grinding

Abstract

The invention discloses a film chuck special for plate part grinding. The film chuck comprises an external diameter clamping device and an end surface clamping device. The external diameter clamping device comprises an oil cylinder driving rod 1, a press claw connecting disc 3, a base disc 4, a film disc 6, an adjusting seat 7 and an outer diameter clamping jaw 8, wherein the adjusting seat 7 is fixed onto the film disc 6, and when the oil cylinder driving rod 1 rightwards drives the press claw connecting disc 3 to move, a semicircular protrusion 301 abuts against the film disc 6 made of spring steel; the end surface clamping device comprises a rotating rod 2, a guide block 18 and an end press claw 11. The film chuck special for plate part grinding has the advantages that two actions can be achieved through a single driving rod, so that simple structure and processing convenience can be achieved; a user just needs to control one action, so that the control process is simple and easy to implement; only one set of control elements and electromagnetic valves are needed, so that the costs can be saved; the inside of a main shaft is large in space for accommodating a detecting device.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a chuck component, more specifically to a special film chuck for grinding disk parts. Background technique [0002] The chuck of traditional disk parts adopts the clamping method of three-jaw positioning on the outer circle and three-jaw pressing on the end face. For the occasion of automatic chucking, an oil cylinder is required for the outer circle positioning and the end face pressing. This mechanism has the following problems: first, the structure of the double oil cylinder is complex, and the processing of the parts is difficult; second, the two actions need to be controlled separately, which increases the difficulty of control; third, two sets of solenoid valves and control components are required, which increases the cost; fourth, In the case of modern processing with higher and higher requirements for precision, it is often necessary to install a device for detecting ...
