Abstract

The utility model discloses a clamp special for turning eccentric shaft parts, which comprises an eccentric sleeve and an elastic live center, wherein the front end of an eccentric shaft part to be machined is arranged in the eccentric sleeve and fixedly connected with a three-claw chuck through the eccentric sleeve, and the tail end of the eccentric shaft part to be machined is supported by the elastic live center. As being formed by a structure that the eccentric sleeve is matched with the center, the clamp special for the turning eccentric shaft parts can eliminate the theoretical calculation of the traditional gasket by operators, greatly reduce the technical requirement of the operators, guarantee the simple operation and the high precision when being turned, and realize quantity production. The center which is used for tightly supporting the parts adopts the elastic live center, thereby preventing the parts from moving, and guaranteeing the machining precision.

Description

The special fixture of the eccentric axial workpiece of a kind of turning
Technical field
The utility model belongs to the turning machine technical field, relates to a kind of special fixture, is specifically related to a kind of anchor clamps that are used for the processing of the eccentric axial workpiece of turning.
Background technology
The main method of the eccentric axial workpiece of turning at present is: three-jaw turning method, four paws turning method, floral disc turning method and three-jaw fine setting turning method etc.Though these methods can reach the purpose of turning eccentric shaft, also there are some defectives.As three-jaw turning method to operator's requirement than higher, require the operator promptly to have the mathematical computations ability and have strong operative skill again; And four paws turning method and floral disc turning method or precision is low, or operability is very poor, and these are all given to produce especially to produce in batches and bring very big inconvenience, now adopt special exclusive clamps prodigiosin handled easily and guarantee precision, can also realize producing in batches.
Therefore, provide a kind of and can guarantee precision, easy to operate, can realize producing in batches, and operator's operative skill is required low turning eccentric shaft class anchor clamps, become the technical barrier that those skilled in the art press for solution.
Summary of the invention
Technical problem to be solved in the utility model provides the good three-dimensional imaging anti-counterfeit package product that has positioning function of a kind of antifalse effect, to overcome the above-mentioned defective that prior art exists.
The technical scheme of the utility model technical solution problem is as follows:
The special fixture of the eccentric axial workpiece of a kind of turning, it is characterized in that, comprise eccentric bushing and elasticity live center, described eccentric shaft part front end to be processed is arranged in the eccentric bushing, grab chuck by eccentric bushing and three and fixedly connected, eccentric shaft part end to be processed withstands by the elasticity live center.
Operation principle of the present utility model: turning add man-hour with eccentric bushing, eccentric axial workpiece by on the scroll chuck that is installed in the lathe headstock shown in Figure 1, clamp suitably; With the elasticity live center that is installed on the lathe tailstock institute's processing parts is suitably held out against again, influence its machining accuracy to prevent the part play.After the accessory turning completion,, take off the part of completion, unprocessed part is installed as long as the elasticity live center is removed.Repeating simple turner operation just can the eccentric axial workpiece of machining high-precision.
By above disclosed technical scheme as can be known, the utility model cooperates an eccentric shaft class of top formation Special Fixture for Machining structure by adopting eccentric bushing, can save the operator calculates the theory of conventional spacers, technical ability to the operator requires also to lower greatly simultaneously, guaranteed eccentric shaft class accessory turning add man-hour simple to operate, precision is high, can also realize producing in batches.The top employing elasticity live center that holds out against part guarantees machining accuracy to prevent the play of part.
The beneficial effects of the utility model are as follows:
(1) strong operability: the dependence to operator's operative skill is very low, and part processing precision is not subjected to artificial factor.
(2) install on request and can process, do not need centering off-centre, axis of workpiece parallel, greatly reduced labor strength, improved production efficiency greatly.
(3) part processing precision interchangeability is good.
(4) the special fixture cost is not high, and economy is good.
Description of drawings
Fig. 1 is specific embodiment structural representation of the utility model special fixture.
Fig. 2 is an elasticity live center structural representation.
Reference numeral is as follows:
1, claw 2, eccentric bushing
3, eccentric axial workpiece 4, elasticity live center
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the special fixture of the eccentric axial workpiece of the utility model turning, comprise eccentric bushing 2 and elasticity live center 4, described eccentric axial workpiece 3 front ends to be processed are arranged in the eccentric bushing 2, fixedly connected with scroll chuck 1 by eccentric bushing 2, eccentric axial workpiece 3 ends to be processed withstand by elasticity live center 4.
Further, the basic numerical value of described eccentric bushing 2 eccentric throws is the same with eccentric axial workpiece to be processed 3.
The eccentric throw tolerance value of described eccentric bushing 2 is 1/4th to 1/3rd of eccentric axial workpiece 3 eccentric throw tolerance values to be processed.
It is H6/h6 that described eccentric bushing 2 cooperates with the installation of eccentric axial workpiece 3 to be processed.
The surface roughness of described eccentric bushing 2 and eccentric axial workpiece 3 phase-contact surfaces to be processed is greater than Ra0.8.
Operability of the present utility model is very strong, and is very low to the dependence of operator's operative skill; Part processing precision interchangeability is good; The special fixture cost is not high.Adopt the utility model perfect method of can yet be regarded as for requirement on machining accuracy than the turning processing of higher or in batches bigger eccentric axial workpiece.
