Embodiment Construction
[0014] The present invention will be described in further detail below in conjunction with examples and specific implementation methods.
[0015] Such as figure 1 As shown, the chuck for automobile flywheel grinding has a structure including a quick press block 7 and a hydraulic cylinder 29, wherein the end of the hydraulic cylinder pull rod 28 of the hydraulic cylinder 29 is provided with a linear bearing 26, and the hydraulic cylinder 29 end on the outside of the linear bearing 26 A positioning flange 1 is set on the part, and a workbench 2 is set on the locating flange 1. The linear bearing 26 is fixed in the hole in the center of the workbench 2. The end of the hydraulic cylinder pull rod 28 is connected to the compression screw 11, and the compression screw 11 is close to the hydraulic pressure. A second spring 15 is arranged on the outer surface of the connecting end of the cylinder pull rod 28, a first spring 9 is arranged on the outer surface of the compression screw 1...

The invention relates to a chuck for automobile flywheel grinding. The chuck is structurally characterized in that the end of a pull rod of a hydraulic oil cylinder is sleeved with a linear bearing; aworkbench is arranged on a positioning flange outside the linear bearing; the linear bearing is fixed in a central hole of the workbench; the end of the pull rod of the hydraulic oil cylinder is connected with a compression screw; a second spring is arranged on the outer side surface of the compression screw; a first spring is arranged on the outer side surface of the other end of the compressionscrew; a positioning sleeve is arranged on the outer side of the second spring; a guide sleeve is arranged on the outer side of the positioning sleeve and fixed to the top surface of the workbench; the outer side of the compression screw at the lower part of the positioning sleeve is sleeved with a sealing cover; the sealing cover is fixedly connected with the inner wall of the central hole of the workbench; a positioning block is arranged on the outer side of the guide sleeve; the positioning block is fixed to the top surface of the workbench; a compression sleeve, a quick pressing block anda pressing plate are arranged on the outer side of the compression screw at the lower end of the first spring sequentially; and a workpiece is placed between the pressing plate and the positioning block and is positioned and fixed through pins. The chuck has the advantages that workpiece clamping and positioning are realized quickly, the machining efficiency is improved, the positioning is rapid,the precision is high and the machining precision is improved.
Description
technical field [0001] The invention relates to a chuck for grinding an automobile flywheel, in particular to a chuck for grinding an automobile flywheel on a numerical control vertical grinding machine. Background technique [0002] Automobile flywheel is an important component structure of the engine, which needs to be ground during production. [0003] In the prior art, the flywheel of the automobile is generally ground on the cylindrical grinder. This processing method is very inconvenient for clamping and the processing efficiency is low. Moreover, the rough processing equipment used in the prior art has slow positioning, poor positioning accuracy, and poor processing accuracy. Suitable for processing thinner automobile flywheels. Contents of the invention [0004] The present invention proposes a chuck for grinding automobile flywheels, and its purpose is to overcome the above-mentioned deficiencies in the prior art and realize fast clamping of automobile flywheel w...
