Abstract
The invention relates to an eccentric clamping fixture. The eccentric clamping fixture is characterized by mainly comprising a base plate, a positioning plate, a pressing plate, an eccentric shaft, a handle and a clamping block, wherein the positioning plate is fixedly connected onto the base plate by virtue of positioning pins and screws, two supporting blocks fixedly connected with the base plate by virtue of the pressing plate are arranged at a parallel position of a longitudinal axis of the positioning plate, the clamping block connected with the side walls of the supporting blocks in a sliding manner is arranged between the two supporting blocks, a center hole of the clamping block penetrates the eccentric shaft, the lower end of the eccentric shaft is connected with a shaft hole of the base plate, and the upper end of the eccentric shaft is connected with the handle. The invention has the beneficial effects that: after a workpiece is positioned and clamped by adopting the eccentric clamping fixture, the machining efficiency of parts is improved by 60-70%; and clamping is completed by eccentricity, thus labour intensity of an operator is greatly alleviated.
Description
Technical field
The invention belongs to machined, relate in particular to a kind of eccentric clamping fixture that is applied to the lamellar part that the surface grinding machine machining accuracy is higher, batch is big.
Background technology
Surface grinding machine processing sheet shape part such as planform are big planes for one side, and another side is a shaped face, and this frock need clamp thin-walled and process big plane.Usually adopt manual clamping mode location, this locate mode can satisfy in a small amount or the single-piece production requirement reluctantly.Mainly the deficiency that exists is, operating efficiency is lower, and labour intensity is big; Main is that qualification rate is not high.This situation is at the machining industry ubiquity, because described situation is at the machining industry ubiquity, so the bottleneck technical problem that the restriction that needs to be resolved hurrily is produced in enormous quantities.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, a kind of eccentric clamping fixture is provided, be suitable on surface grinding machine machining accuracy height, big lamellar part in batches, can raise the efficiency, reduce labor intensity, make the ratio of effective process time and secondary process time big.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of eccentric clamping fixture, it is characterized in that: mainly by base plate, location-plate, pressing plate, eccentric shaft, handle and clamp constitute, described location-plate is fixed on the base plate by alignment pin and screw, the parallel position of described location-plate longitudinal axis is provided with by pressing plate and two affixed back-up blocks of base plate, be provided with the clamp that is slidingly connected with the back-up block sidewall between described two back-up blocks, run through eccentric shaft in the described clamp centre bore, described eccentric shaft lower end is connected with the base plate axis hole, and the eccentric shaft upper end is connected with handle.
Beneficial effect: after adopting above-mentioned eccentric frock to workpiece location, clamping, the working (machining) efficiency of part has improved 60%-70%; Finish by off-centre owing to clamp, alleviated operator's labour intensity greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of eccentric shaft and clamp among Fig. 1;
Fig. 3 is the structural representation of clamp.
Among the figure: 1, base plate 2, location-plate 3, soket head cap screw 4, alignment pin 5, pressing plate 6, handle 7, eccentric shaft 8, clamp 9, back-up block
The specific embodiment
Below in conjunction with preferred embodiment, to details are as follows according to the specific embodiment provided by the invention: see accompanying drawing for details, a kind of eccentric clamping fixture, mainly by base plate 1, location-plate 2, pressing plate 5, eccentric shaft 7, handle 6 and clamp 8 constitute, described location-plate is fixed on the base plate by alignment pin 4 and soket head cap screw 3, the parallel position of described location-plate longitudinal axis is provided with by pressing plate and two affixed back-up blocks 9 of base plate, be provided with the clamp that is slidingly connected with the back-up block sidewall between described two back-up blocks, run through eccentric shaft in the described clamp centre bore, described eccentric shaft lower end is connected with the base plate axis hole, and the eccentric shaft upper end is connected with handle.
The course of work:
(1) workpiece is packed in the clamping breach of location-plate and clamp,
(2) pull handle, eccentric shaft rotation drive clamp is moved to the locating piece direction workpiece is all clamped;
(3) start process equipment and process,
(4) completion of processing;
(5) spanner handle makes eccentric shaft rotate the drive clamp and moves in the other direction to locating piece, and workpiece unclamps;
(7) take out the workpiece that processes, prepare next circulation.
According to the appearance and size of workpiece, the length of the complicated and simple and process time of operation can be amplified location-plate, loads onto several bodies, to obtain high working (machining) efficiency.Device body is an elementary cell, and several device bodies are installed on a base plate, according to most effective principle, use wherein partly or entirely.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
