Description

A kind of fixture of Quick-clamped
Technical field
The present invention relates to field of machining, particularly after Workpiece fixing to the fixture carrying out Quick-clamped of workpiece.
Background technology
At present, during machining, after workpiece is located on the fixture of platen, Workpiece clamping and unclamping generally acts on by briquetting that workpiece realizes.Realize said process and mainly contain following several mode:
One, mechanical type: twist nut by spanner and screw rod screws, realizes the axially-movable of the relative screw rod of nut, and acts on briquetting.This screw rod is in the centre of briquetting, and there is support one end of briquetting, and another acts on workpiece.Its defect need be carried out with spanner when clamping workpiece and dismounting, when clamping point is more, takes time and effort very much, inefficiency.
Two, fluid pressure type: by the cylinder efficient in hydraulic system, the pull bar of oil cylinder is connected with briquetting, when oil cylinder backward stick action, briquetting accompany movement, thus realize the clamping of workpiece and unclamp.To be hydraulically operated fixture and lathe be its defect carries out special for a kind of product of batch machining, and the oil circuit of hydraulically operated fixture is placed in platen, and cylinder efficient position is also that relative processing work designs and fixes.When batch machining replacement of products kind, the clamping point position of its oil circuit, hydraulically operated fixture, cylinder efficient position need specialized factory to redesign layout, change very difficult.Hydraulically operated fixture also has cost high, oil consumption power consumption, the shortcomings such as maintenance workload is large.
Three, vapour-pressure type: the pull bar of cylinder is connected with briquetting, when air cylinder tie rod action, briquetting accompany movement, thus realize the clamping of workpiece and unclamp.To be air-actuated jaw and lathe be its defect carries out special for a kind of product of batch machining, when batch machining product carries out replacing kind, is suitable for difficulty.Air clamp has clamping force inadequate, and it is unreliable etc. to clamp.
Summary of the invention
For the deficiency of above-mentioned mechanical type, fluid pressure type and vapour-pressure type fixture, when the object of this invention is to provide Workpiece clamping and unclamp operating efficiency high, when changing product fixture easily change, the fixture of the reliable a kind of Quick-clamped of clamping force.
The fixture of this Quick-clamped, it is characterized in that, comprise 2-3 are implemented clamping briquetting to workpiece, described briquetting is all connected with same float plate, float plate relies on the support of spring, and be provided with lever between float plate and workpiece, middleware contacts with float plate with lever respectively, lever one end is fulcrum and position of the fulcrum governor motion, and the other end of lever is power point and corresponding actuating unit.
Briquetting and float plate be connected with two kinds of modes: directly and float plate chain connection, also can be connected by connecting rod with float plate.
The support of the floating dependence spring of float plate, support pattern has two kinds, and one arranges spring in float plate bottom, and one is hung by float plate spring.
The center of gravity of described briquette structure in corresponding roller side, described briquetting under Gravitative Loads with described corresponding roller contact.
