Description
Technical field
This utility model relates to the fixture in small crankshaft processing technique field, especially a kind of small crankshaft car bias Special clamping device.
Background technology
Compressor small crankshaft shape matching is special, it is carried out turning and face work adds man-hour, owing to upper and lower bent axle has the requirement of centre-to-centre spacing and position degree, therefore significantly high to clamping required precision.If directly clamping is processed on lathe, not only surface of the work has impression, it is necessary to the later stage repairs, and clamping speed is slow, and precision and the symmetry of processing are very poor, it is impossible to reach requirement.In order to overcome drawbacks described above, dedicated lock set can be used to be clamped, and this lock tube is both for the small crankshaft of each specification and custom-designed, therefore its pointed strong, the advantage that can meet machining accuracy, but it equally exists a lot of weak point: 1, lock tube is more expensive, cost is high.2, the workpiece of every kind of lock tube only corresponding a kind of specification, it is therefore desirable to be equipped with multiple lock tube, not only adds production cost, and all makes troubles to the management of process operation and lock tube.Need to readjust position when 3, remodeling, relatively time-consuming.
Utility model content
The purpose of this utility model is in that to make up the deficiencies in the prior art part, it is provided that a kind of easy to use, low cost of manufacture and can accelerate the small crankshaft car bias Special clamping device of manufacturing schedule.
The purpose of this utility model is realized by techniques below means:
A kind of small crankshaft car bias Special clamping device, it is characterized in that: include main body sleeve, the dish that is strained and fixed, coning sleeve, locking collet chuck, eccentric bushing and cover plate, eccentric bushing is made an axial workpiece installing hole, the axis of this workpiece installing hole and the axis of eccentric bushing be arranged in parallel, and that eccentric bushing is made one or more connects with workpiece installing hole is axially grooved；Eccentric bushing is coaxially inserted in a locking collet chuck, and the top, rear end of this locking collet chuck is pressed on the boss that main body sleeve inner is made；At one coning sleeve of outside coaxial package of locking collet chuck, this coning sleeve is contact of incline plane with locking collet chuck, the coaxially connected dish that is strained and fixed in rear end of this coning sleeve, and described coning sleeve and the dish that is strained and fixed all are sleeved in the axis hole of main body sleeve；The front end face of this main body sleeve is co-axially mounted cover plate, and the top, front end of locking collet chuck is pressed in the inner side of cover plate.
And, one of them axially grooved end made on described eccentric bushing connects with the sidewall of eccentric bushing, and other axially grooved ends respectively connect a circle hole groove.
And, the front end face of described eccentric bushing makes a screwed hole.
And, the sidewall of described locking collet chuck makes axial side channel.
And, via to be made by the boss that described main body sleeve inner is made, in this via, installs adapter sleeve, the dish that is strained and fixed, adapter sleeve and coning sleeve are connected by screw.
Advantage of the present utility model and having the benefit effect that
1, coning sleeve and the locking sleeve of contact of incline plane are set, by the movement of coning sleeve, it is possible to make the eccentric bushing locking workpiece in locking sleeve, be processed in the main body sleeve of this device.This mode is simple and convenient, locking positioning is effective, it can be ensured that machining accuracy reaches requirement.
2, owing to have employed eccentric bushing locking mechanism, therefore can the workpiece of different size being locked, not only the operation for staff is provided convenience, it is simple to the management of fixture, but also reduces cost payout.
3, this device replacing workpiece and replacing eccentric bushing are very convenient, and speed is fast.
4, this apparatus structure is simple and practical, low cost of manufacture.
5, this utility model is a kind of to design small crankshaft car bias Special clamping device ingenious, rational in infrastructure, easy to use, that cost is low, clamping is stable, improve crudy, faster production to use this device ensure that, is particluarly suitable in large-scale batch production and uses.

Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing；It should be noted that the present embodiment is narrative, it not determinate, it is impossible to limit protection domain of the present utility model with this.
A kind of small crankshaft car bias Special clamping device, including main body sleeve 7, the dish 5 that is strained and fixed, coning sleeve 8, locking collet chuck 2, eccentric bushing 3 and cover plate 1, eccentric bushing is made an axial workpiece installing hole 10, the axis of this workpiece installing hole and the axis of eccentric bushing be arranged in parallel, and namely workpiece installing hole and eccentric bushing are not coaxial.Make on eccentric bushing that one or more connects with workpiece installing hole axially grooved 11, one of them axially grooved end connects with the sidewall of eccentric bushing, and other axially grooved ends respectively connect a circle hole groove 12.The front end face of eccentric bushing makes a screwed hole 9, it is possible to pulled down by eccentric bushing very easily.
Eccentric bushing is coaxially inserted in a locking collet chuck, and the sidewall of this locking collet chuck is made axial side channel, and the top, rear end of this locking collet chuck is pressed on the boss that main body sleeve inner is made.One coning sleeve of outside coaxial package at locking collet chuck, this coning sleeve is contact of incline plane with locking collet chuck, the coaxially connected dish that is strained and fixed in rear end of this coning sleeve, its concrete structure is: make via on the boss that main body sleeve inner is made, installing adapter sleeve 6 in this via, the dish that is strained and fixed, adapter sleeve and coning sleeve are connected by screw.Above-mentioned coning sleeve, adapter sleeve and the dish that is strained and fixed all are sleeved in the axis hole of main body sleeve.The front end face of this main body sleeve is co-axially mounted cover plate, and the top, front end of locking collet chuck is pressed in the inner side of cover plate.
Using method of the present utility model is:
Being inserted in the workpiece installing hole of eccentric bushing by workpiece 4, the dynamic coning sleeve of the dribbling that is strained and fixed travels forward, and compressing locking collet chuck and eccentric bushing, thus being locked by workpiece, can be processed.After work pieces process completes, be strained and fixed dish rearward movement, and coning sleeve unclamps with locking collet chuck, and eccentric bushing also unclamps, and namely can be taken off workpiece.
