Description
Technical field
The utility model relates to a kind of taper shank automatic clamping device.
Background technology
In the time of the workpiece of processing belt taper shank, need taper shank positioning clamping reprocessing workpiece.The clamping of general taper shank is fix and locate by the frictional force of shank male cone (strobilus masculinus), so the outer surface of taper shank will have less surface roughness to guarantee its chucking power.And the conical surface of its taper shank is not also processed through fine finishining mill in roughing, its surface accuracy is also not enough to enough frictional force and carrys out holding workpiece, because the diametric error of tapering causes the change in size of workpiece spindle to length direction, affect the processing dimension of workpiece end face simultaneously.As first carried out the mill processing of shank, because also needing the processing such as heat treatment after milling processing, must re-start mill processing, will increase like this processing cost.In the time of clamping, will have enough axial forces in addition, the conical surface is fitted tightly just can have required frictional force to guarantee can not become flexible in process, but after processing, just needs larger axial force to eject workpiece.So the automatic clamping of taper shank is difficult to solve, and can only lean on artificial clamping always.
Utility model content
The purpose of this utility model is to provide a kind of taper shank automatic clamping device, solves the automatic clamping fixation problem of roughing taper shank, realizes continuous automatic clamping and release.
The technical solution of the utility model is such: a kind of taper shank automatic clamping device, it is characterized in that, comprise cylinder, push rod, main shaft, protecgulum and spring chuck, described cylinder comprises cylinder body and push rod, described push rod is provided with axially extending bore, described push rod is arranged in the axially extending bore of push rod, described main shaft is quill shaft, described push rod is arranged in main shaft, push rod head end is fixedly connected with lock sleeve, the head end of described lock sleeve is provided with taper hole, the head end of described main shaft is provided with protecgulum, the medial surface of described protecgulum is provided with taper hole, described spring clip is set in main shaft, between protecgulum and lock sleeve, the both ends of the surface of described spring chuck are provided with the conical surface matching with lock sleeve taper hole and protecgulum taper hole respectively, in spring chuck, are provided with taper hole, and described spring clip puts and is provided with some axial grooves, make spring chuck two ends be many valve structures.
In a specific embodiment of the present utility model, the head end axial groove of described spring chuck and tail end axial groove are circumferentially interspersed along spring chuck, and described axial groove length is greater than 1/2nd of spring chuck length.
The advantage of technical scheme provided by the utility model is,
1. taper shank to be held does not need fine finishining, just can realize the clamping and positioning of shank.
2. workpiece can axial location in this clamping device, the uniformity of holding workpiece axial dimension.
3. owing to all slotting in spring chuck two ends, the large end small end of taper shank contacts simultaneously, increases contact-making surface, improves clamping force, clamps more reliable.
4. can realize automatic clamping and the release of taper shank, without manual operation intervention, be beneficial to automated production.

Fig. 2 is this spring clip nested structure schematic diagram;
Fig. 3 is that the AA of Fig. 2 is to sectional structure schematic diagram.
The specific embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Incorporated by reference to Fig. 1, Fig. 2 and Fig. 3, taper shank automatic clamping device comprises cylinder 1, push rod 2, main shaft 3, protecgulum 4 and spring chuck 5, cylinder 1 comprises cylinder body 1a and push rod 1b, push rod 1b is provided with axially extending bore 1c, push rod 2 is arranged in the axially extending bore 1c of push rod 1b, main shaft 3 is quill shaft, and the tail end of main shaft 3 is fixedly connected with cylinder connection cover 1d.Push rod 1b is arranged in main shaft 3, and push rod 1b head end is fixedly connected with lock sleeve 6, and the head end of lock sleeve 6 is provided with taper hole 7, the head end of main shaft 3 is provided with protecgulum 4, the medial surface of protecgulum 4 is provided with taper hole 8, and the lateral surface of protecgulum 4 is also provided with charging hole 9, and charging hole 9 is communicated with taper hole 8.Spring chuck 5 is arranged in main shaft 3, between protecgulum 4 and lock sleeve 6; The both ends of the surface of spring chuck 5 are provided with the conical surface 5a matching with lock sleeve taper hole 7 and protecgulum taper hole 8 respectively, are provided with taper hole 5b in spring chuck 5, and spring chuck 5 is provided with some axial groove 5c, make spring chuck 5 two ends be many valve structures.The head end axial groove 5c ' of spring chuck 5 and tail end axial groove 5c " along being circumferentially interspersed of spring chuck 5, axial groove 5c length is greater than 1/2nd of spring chuck 5 length.When process operation, by feed mechanism, the taper shank of parts to be processed 10 is sent in the taper hole 5b of spring chuck 5 by protecgulum 4 charging holes 9, push rod 2 is by an air cylinder driven to precalculated position, and taper shank 10 relies on push rod 2 to carry out axial location.Then promoting lock sleeve 6 by the ejecting rod of cylinder 1b of taper shank automatic clamping device moves to protecgulum 4 directions main shaft 3 is interior, the taper hole of lock sleeve 6 and protecgulum 4 acts on respectively the rear and front end conical surface 5a of spring chuck 5, makes many valve structures at spring chuck 5 two ends inwardly shrink large end and the small end of clamp column taper shank respectively.After Workpiece clamping, can carry out corresponding process operation, after machining, cylinder resets, and push rod 1b regains backward, and many valve structures at spring chuck 5 two ends open naturally, workpiece taper shank 10 is released, continue forward end motion by push rod 2 workpiece taper shank 10 is ejected in spring chuck 5, be reset to precalculated position with rear push-rod 2, for the taper shank of next workpiece to be held carries out axial location, and so forth, constantly clamp and release movement.
