Description
Technical field
The present invention relates to Machining Technology field, particularly to a kind of adjustable clamping device for multidiameter.
Background technology
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.At present, the common general clamping force of multidiameter clamping device is non-adjustable, and the suitability is poor.
Summary of the invention
It is an object of the invention to provide a kind of adjustable clamping device for multidiameter, not only can realize the Quick-clamped to multidiameter, and clamping force is adjustable, the suitability is strong.
The technical solution adopted for the present invention to solve the technical problems is:
nullA kind of adjustable clamping device for multidiameter，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、Spacing regulation screw、Supporting screw、Adjusting nut、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 supporting screw is threaded in the lower end of L-shaped pressing plate，One end of described supporting screw is provided with dome，The most threaded on described supporting screw have adjusting nut，The screw mounting groove of level it is provided with on bearing support，Described spacing regulation screw thread is arranged on screw mounting groove.
Further, described spacing regulation screw is slotted head screw.
Further, the inner side of described elastic clip cylinder upper end is provided with clamping spring washer.
Further, the other end of described handle is provided with annular knurl.
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.The inner side of elastic clip cylinder upper end is provided with clamping spring washer, decreases crushing of multidiameter when clamping, significantly protects multidiameter.On the other hand, cam forces two L-shaped pressing plates to swinging the wide section clamping of multidiameter.By the adjustment of spacing regulation screw position, the adjustment of L-shaped pressing plate amplitude of fluctuation can be realized.The other end of handle is provided with annular knurl, and handle is gripped by beneficially operator, substantially increases the convenience of operation.When clamping force needs to adjust, unscrew adjusting nut, adjust the position of supporting screw, tighten adjusting nut the most again.One end of supporting screw is provided with dome, is conducive to and cam laminating.When supporting screw adjusts laterally, clamping force diminishes；When supporting screw adjusts to inner side, clamping force becomes big.Spacing regulation screw is slotted head screw, it is simple to the adjustment of spacing adjustment screw position.The present invention not only can realize the Quick-clamped to multidiameter, and clamping force is adjustable, and the suitability is strong.

Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following example are explanation of the invention and the invention is not limited in following example.
As depicted in figs. 1 and 2, a kind of adjustable clamping device for multidiameter, it includes frame 1, bearing support 2, cam 3, cam props up bearing 4, handle 5, tapered sleeve 6, elastic clip cylinder 7, rotation stopping screw 8, L-shaped pressing plate 9, bearing pin 10, spacing regulation screw 11, supporting screw 12, adjusting nut 13, fixed support 20, described bearing support 2 is fixed in frame 1, described cam props up bearing 4 and is arranged in frame 1, described cam 3 is rotatably provided in cam and props up in bearing 4, one end of described handle 5 and the fixing connection of cam 3, the other end of described handle 5 is provided with annular knurl 18, be conducive to operator that handle 5 is gripped, substantially increase the convenience of operation.The endoporus of described cam 3 and the lower end of elastic clip cylinder 7 are threaded; described elastic clip cylinder 7 can slide up and down and be arranged in tapered sleeve 6; described tapered sleeve 6 is arranged on bearing support 2; the inner side of described elastic clip cylinder 7 upper end is provided with clamping spring washer 17; decrease crushing of multidiameter 19 when clamping, significantly protect multidiameter 19.Being provided with U-type groove 14 on described elastic clip cylinder 7, described rotation stopping screw 8 is arranged on bearing support 2, and inserts in U-type groove 14, and described fixed support 20 is arranged on the upper end of bearing support 2, and described L-shaped pressing plate 9 is hinged on fixed support 20 by bearing pin 10.Described supporting screw 12 is threaded in the lower end of L-shaped pressing plate 9, and one end of described supporting screw 12 is provided with dome 15, is conducive to and cam 3 is fitted.The most threaded on described supporting screw 12 have adjusting nut 13.Being provided with the screw mounting groove 16 of level on bearing support 2, described spacing regulation screw 11 is threadably mounted on screw mounting groove 16, and described spacing regulation screw 11 is slotted head screw, it is simple to the adjustment of spacing adjustment screw 11 position.
Pass through technique scheme, when a kind of adjustable clamping device for multidiameter of the present invention uses, when operator's gripping handle 5 rotates cam 3, owing to the endoporus of cam 3 is threadeded with elastic clip cylinder 7, and elastic clip cylinder 7 is limited can not be turned round by rotation stopping screw 8, therefore it will move down and contraction distortion under the effect of tapered sleeve 6, the thin diameter section of multidiameter 19 is felt relieved clamping.On the other hand, cam 3 forces two L-shaped pressing plates 9 to swinging the wide section clamping of multidiameter 19.By the adjustment of spacing regulation screw 11 position, the adjustment of L-shaped pressing plate 9 amplitude of fluctuation can be realized.When clamping force needs to adjust, unscrew adjusting nut 13, adjust the position of supporting screw 12, tighten adjusting nut 13 the most again.When supporting screw 12 adjusts laterally, clamping force diminishes；When supporting screw 12 adjusts to inner side, clamping force becomes big.The present invention not only can realize the Quick-clamped to multidiameter 19, and clamping force is adjustable, and the suitability is strong.
