Abstract
The utility model relates to an eccentricity lamping fixture which is characterized by mainly consisting of a bottom plate, a positioning plate, a pressure plate, an eccentric shaft, a handle and a clamping bock, wherein the positioning plate is fixedly connected on the bottom plate through positioning pins and screws; two support blocks fixedly connected with the bottom plate through the pressure plate are arranged at the parallel positions of the longitudinal axis of the positioning plate; the clamping lock connected with the side walls of the support blocks in a sliding way is arranged between the two support blocks; the eccentric shaft penetrates through a center hole of the clamping block; the lower end of the eccentric shaft is connected with an axle hole of the bottom plate; and the upper end of the eccentric shaft is connected with the handle. The eccentricity clamping fixture has the beneficial effects that after the eccentric fixture is adopted for positioning and clamping workpieces, the processing efficiency of parts is improved by 60% to 70%; and as the clamping is completed by eccentricity, the labor intensity of an operator is greatly reduced.
Description
Technical field
The utility model belongs to machined, relates 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 of existence 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 said 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.
The utility model content
The utility model is in order to overcome deficiency of the prior art; A kind of eccentric clamping fixture is provided; Be suitable for the lamellar part that machining accuracy is high on surface grinding machine, batch is big, can raise the efficiency, reduce labor intensity, make the ratio of effective process time and secondary process time big.
The utility model is for realizing above-mentioned purpose; Realize that through following technical scheme a kind of eccentric clamping fixture is characterized in that: mainly be made up of base plate, location-plate, pressing plate, eccentric shaft, handle and clamp; Said location-plate is fixed on the base plate through alignment pin and screw; The parallel position of said location-plate longitudinal axis is provided with through pressing plate and two affixed back-up blocks of base plate, is provided with the clamp that is slidingly connected with the back-up block sidewall between said two back-up blocks, runs through eccentric shaft in the said clamp centre bore; Said 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%; Lean on eccentric the completion owing to clamp, alleviated operator's labour intensity greatly.
Description of drawings
Fig. 1 is the utility model structural representation;
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; Details are as follows to the specific embodiment that provides according to the utility model: see accompanying drawing for details, a kind of eccentric clamping fixture mainly is made up of base plate 1, location-plate 2, pressing plate 5, eccentric shaft 7, handle 6 and clamp 8; Said location-plate is fixed on the base plate through alignment pin 4 and soket head cap screw 3; The parallel position of said location-plate longitudinal axis is provided with through pressing plate and two affixed back-up blocks 9 of base plate, is provided with the clamp that is slidingly connected with the back-up block sidewall between said two back-up blocks, runs through eccentric shaft in the said clamp centre bore; Said 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 the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
