Abstract

The invention belongs to the field of machine tool fixture design, and particularly relates to a linkage lever pressing device. Through the adoption of lever linkage and hydraulic linkage, parts to be milled can be pressed in a high place; automation is a main development direction of machine tool fixtures, traditional manual pressing manner becomes a bottleneck of automated production, and the problem needs to be solved through adopting a novel pressing device. The linkage lever pressing device achieves quick part clamping and disassembly on a machining production line.

Description

A kind of linkage lever hold down gag
Technical field
The invention belongs to Machine Tool Fixture Design field, be specifically related to a kind of linkage lever hold down gag, by adopting lever interlock and hydraulic-driven, can realizing wanting the part of milling to compress aloft.
Background technology
Automation is a Main way of jig development, and traditional compresses the bottleneck that mode becomes automated production manually, needs to adopt novel hold down gag to solve problems.
Summary of the invention
Technical problem to be solved by this invention is: add on production line at machine, realizes fast clamp and the dismounting of part.
The technical solution adopted in the present invention is: a kind of linkage lever hold down gag, for being fixed part when Milling Process, this hold down gag comprises clamp body, pushes away cylinder, pushes away cylinder head, slide block, floating platen, hinge pressing plate, rotating shaft, spring housing, return spring and compact heap, wherein
Described clamp body has the hole of mounting parts at middle part, the rotating shaft at two ends, left and right with hinge pressing plate is connected, and is fixed with in both sides, front and back and pushes away cylinder;
Connected by described rotating shaft between often pair of hinge pressing plate, two pairs of hinge pressing plates are mounted opposite, and each hinge pressing plate upper end inner surface is provided with described compact heap, bottom arranged outside has spring housing for return and return spring, and bottom inwardly has projection;
Push away cylinder extend downwards described in push away cylinder head, this pushes away cylinder head lower end and is connected with slide block, and slide block is connected with floating platen; The U-shaped structure of this floating platen, and at opening two ends, there is outward extending inclined plane, matching with the projection of hinge pressing plate, by promoting floating platen downwards, hinge pressing plate can be rotated around rotating shaft.
This device also comprises base plate, guide post and Compress Spring, and base plate is arranged on the downside of floating platen by guide post and Compress Spring, for buffering.
Hinge pressing plate has the surface relative with clamp body, and the described spring housing for return and return spring are arranged on clamp body or hinge pressing plate.
Described slide block is connected with the end bosses pushing away cylinder head by the T-slot on top; Slide block bottom is having U-type groove, for installing with floating platen.
By the control of hydraulic system, push away cylinder head and drive floating platen to move up and down, thus drive hinge pressing plate open or compress motion.
Advantage of the present invention is: by hydraulic control, can realize the fast-holding of lever and unclamp, and thrust is large, can solve the compression of long cantilever part.
