Grinding and clamping device of big spring

Abstract

The invention discloses a grinding and clamping device of a big spring. The grinding and clamping device comprises an air cylinder, upright posts, a V-shaped pressing block, a V-shaped locating block, a screw rod, a carriage, a work platform, a square nut, an air pressure station, a button box and a supporting plate, wherein the air cylinder is connected with the supporting plate through bolts, the V-shaped pressing block is connected with a stretching shaft of the air cylinder through screws, the carriage and the supporting plate are connected through four upright posts of which two ends are provided with threads and are locked through hexagonal nuts, the V-shaped locating block is fastened on the carriage through screws, the square nut is arranged just under the carriage, the screw rod the square nut adopt transmission threaded connection, the carriage is in sliding connection with the work platform through a dovetail groove structure, the air pressure station is connected with the air cylinder through a pipeline, and the button box is connected with the air pressure station through a guide line. According to the grinding and clamping device of the big spring, disclosed by the invention, the operation is simple, the locating accuracy is high, the clamping is reliable, the automation degree is high, and the production efficiency can be obviously increased.

Description

technical field [0001] This invention relates to clamps, and more particularly to large spring grinding clamps. Background technique [0002] At present, when large springs are ground, most of them use the method of manually pressing the springs with a pressure plate. When clamping, it is labor-intensive and time-consuming, and the clamping force is not large, which is easy to produce concessions and affects the grinding progress and accuracy. In this way, the production efficiency is low and the grinding accuracy is poor. Contents of the invention [0003] The object of the present invention is to provide a large spring grinding and clamping device with simple operation, high positioning accuracy, reliable clamping, high degree of automation and significantly improved production efficiency. [0004] In order to achieve the above object, the present invention includes a cylinder, a column, a V-shaped pressure block, a V-shaped positioning block, a screw mandrel, a carriag...
