Abstract

The invention discloses a novel adjustable eccentric clamping head. The tail part of a clamping head body is made into a handle shape; a swallow tailed or other forms of guide rail is manufactured on a head plane of the clamping head body; and the guide rail is symmetrical with the central axial line of the tail part of the guide rail. One end of an elastic clamping head is provided with a flange-shaped combining end; a guide rail is manufactured at the combining end and is matched with the guide rail on the clamping head body; a slotted hole is formed at the combining end of the elastic clamping head; and a fixing bolt fixes the elastic clamping head on the head plane of the clamping head body through the slotted hole. Proper positions at the combining end of the elastic clamping head and the head plane of the clamping head body are provided with vernier scales, and a main scale of the vernier scales is arranged on the head plane of the clamping head body; the elastic clamping head is adjusted to move in the guide rail; and an adjusting screw is arranged on two sides of a proper position on the head plane of the clamping head body respectively. The clamping head part of the elastic clamping head is provided with a locking nut.

Description

A kind of novel adjustable eccentric clamping head
Technical field
The present invention relates to a kind of adjustable eccentric clamping head, particularly a kind of novel adjustable eccentric clamping head.Belong to the Machining Technology field.
Background technology
In machining, the workpiece that runs into the eccentric shaft class through regular meeting needs processing, and at present, in the processing of eccentric shaft, the main method of taking is: the one, and directly processing on Digit Control Machine Tool; The 2nd, design special eccentric fixture and on machine tool, process; The 3rd, with the machine tooling of special processing eccentric shaft class.In above-mentioned processing method, all there are some defectives to some extent.Adopt the Digit Control Machine Tool and the method for special lathe all to have the bigger defective of equipment investment, general medium-sized and small enterprises or handicraft workshop do not have enough economic capabilities, designing special eccentric fixture processes on machine tool, though equipment investment is few, but manufacture and design eccentric fixture and need certain cycle, the versatility of process equipment is relatively poor simultaneously, after product parts is changed, and the also necessary replacing simultaneously of corresponding tool equipment.
Summary of the invention
The objective of the invention is to: a kind of novel adjustable eccentric clamping head is provided, it is convenient that processing to eccentric shaft-like workpiece need in processing, overcome in the prior art, the higher defective of equipment investment cost that adopts Digit Control Machine Tool or special machine tooling eccentric shaft to be had, simultaneously also be on machine tool, to process in order to overcome the special eccentric fixture of design, manufacture and design eccentric fixture and need certain cycle, the versatility of process equipment is relatively poor, after product parts is changed, the defective that corresponding tool equipment also must be changed simultaneously.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of novel adjustable eccentric clamping head, it is made up of major parts such as adjustment screw, set bolt, chuck body, collet, chuck lock nut, vernier scales.Described chuck body afterbody is made the handle shape, its appearance and size matches with corresponding machine tool chief axis hole, the head of described chuck body is made plane, and form vertical relation with afterbody, on the header planes of chuck body, produce the guide rail a of dove-tail form or other form, guide rail a and the afterbody central axis symmetry of self.Described collet, the one end is made the binding end of flange-like, the Flange Plane of binding end is vertical with the collet central axis, produce guide rail at binding end, its guide rail and chuck guide rail on one's body matches, collet make slotted hole in conjunction with the end, set bolt is fixed on collet on the header planes of chuck body by slotted hole.In conjunction with the appropriate location on the header planes of end and chuck body vernier scale is installed at collet, the main scale of oil scale is installed on the header planes of chuck body, secondary chi be installed in collet in conjunction with the end, in practice, also can according to circumstances both change installation.For the ease of regulating collet moving in guide rail, the adjustment screw of installation of the both sides, appropriate location on the header planes of chuck body.For the ease of clamping, be provided with at the chuck position of collet locking nut has been installed workpiece.
During work, the handle shape of chuck body is partly inserted in the spindle hole of machine tool.Loosen two set bolts, regulate two adjustment screw, make the central axis of collet and the centre of gyration of main shaft that suitable skew be arranged, its side-play amount is read by vernier scale, reach suitable side-play amount after, from new locked clamping screw.Workpiece is inserted in the collet, tighten locking nut, promptly can begin processing.
Beneficial effect: owing to adopted such scheme, effectively having solved the method that adopts Digit Control Machine Tool and special lathe, all to have an equipment investment bigger, and general medium-sized and small enterprises or handicraft workshop do not have the defective that enough economic capabilities are born.Effectively solved again and designed special eccentric fixture and on machine tool, process, though equipment investment is few, manufacturing and designing eccentric fixture needs certain cycle, and the versatility of process equipment is relatively poor simultaneously, after product parts is changed, the defective that corresponding tool equipment also must be changed simultaneously.
