Machining refers to the process being changed overall dimensions or the performance of workpiece by a kind of plant equipment.Machining and pressure processing can be divided into by the difference on processing mode.In process of production, every change produces the shape of object, size, position and character etc. so that it is the process becoming finished product or semi-finished product is referred to as technical process.It is the major part of production process.Technical process can be divided into again the technical processs such as casting, forging, punching press, welding, machining, assembling, manufacturing technology process generally refers to the machining work process of part and the summation of the assembling technology procedure of machine, other processes are then referred to as supporting process, such as transport, take care of, power supply, maintenance of equipment etc..Technical process is made up of one or several tactic operations again, and an operation is formed by by several work steps.Multidiameter is a kind of common part, firstly the need of being clamped in the course of processing, just can be processed after clamping.The most common clamping device such as vices etc. are poor to the clamping effect of multidiameter.
Summary of the invention
It is an object of the invention to provide the clamping device of a kind of multidiameter, quickly realize multidiameter thin diameter section and wide section synchronous clamping, rational in infrastructure, good clamping effect.
The technical solution adopted for the present invention to solve the technical problems is:
nullA kind of clamping device of multidiameter，It is characterized in that: it includes frame、Bearing support、Cam、Cam props up bearing、Handle、Tapered sleeve、Elastic clip cylinder、Rotation stopping screw、L-shaped pressing plate、Bearing pin、Compression spring、Pressure pad、Ejector pin、Fixed support，Described bearing support is fixed in frame，Described cam props up bearing and is arranged in frame，Described cam is rotatably provided in cam and props up in bearing，One end of described handle and the fixing connection of cam，The endoporus of described cam and the lower end of elastic clip cylinder are threaded，Described elastic clip cylinder can slide up and down and be arranged in tapered sleeve，Described tapered sleeve is arranged on bearing support，It is provided with U-type groove on described elastic clip cylinder，Described rotation stopping screw is arranged on bearing support，And insert in U-type groove，Described fixed support is arranged on the upper end of bearing support，Described L-shaped pressing plate passes through hinge on fixed support，Described L-shaped pressing plate lower end is provided with ejector pin，Spring-loaded groove it is provided with on bearing support，Described compression spring is arranged in spring-loaded groove，One end of compression spring is provided with pressure pad，Described pressure pad is fitted with L-shaped pressing plate under the effect of compression spring.
Further, the other end on described handle is provided with gripping bulb.
Further, the inner side of described elastic clip cylinder upper end is provided with clamping spring washer.
The present invention is compared to the prior art, have the following advantages and effect: when operator's gripping handle rotates cam, owing to the endoporus of cam is threadeded with elastic clip cylinder, and elastic clip cylinder is limited can not be turned round by rotation stopping screw, therefore it will move down and contraction distortion under the effect of tapered sleeve, the thin diameter section of multidiameter is felt relieved clamping.On the other hand, under the effect of compression spring, the ejector pin of L-shaped pressing plate lower end is fitted with cam all the time, and cam forces two L-shaped pressing plates to swinging the wide section clamping of multidiameter.The other end on handle is provided with gripping bulb, beneficially operator and operates handle.The inner side of elastic clip cylinder upper end is provided with clamping spring washer, decreases crushing of multidiameter when clamping, significantly protects multidiameter.The present invention quickly realizes multidiameter thin diameter section and wide section synchronous clamping, rational in infrastructure, good clamping effect.
