Abstract

The utility model provides a device for turning eccentric workpieces used in an engine lathe, which comprises a cone, wherein the cone is provided with a fastening plate, a clamping hole is arranged in the fastening plate, a centerline L2 of the clamping hole is parallel to and not collinear with a centerline L1 of the cone, the clamping hole is provided with an elastic groove and an elastic hole that are communicated with each other, and a tightening screw is arranged on the fastening plate at the end provided with the elastic groove. The device has the following advantages: in operation, distance between the center of the clamping hole and the rotary center of the cone is adjusted according to eccentricity of a part to be machined, the tightening screw is screwed after the installation of the workpiece, and the workpiece is locked by virtue of deformation of the elastic groove and the elastic hole on the fastening plate. The device is simple in structure and convenient in operation, greatly improves the production efficiency, can be produced in batches, and is suitable for being used for turning eccentric shafts or eccentric sleeve workpieces used in the engine lathe.

Description

Engine lathe car eccentric work piece device
Technical field
The utility model relates to a kind of lathe apparatus, relates to the device of a kind of engine lathe with turning eccentric shaft or eccentric bushing specifically.
Background technology
From the transmission principle and the scope of application of lathe, engine lathe can only be processed workpiece with one heart such as concentric shafts or concentric locking collar, and the function of not processing eccentric workpiece such as eccentric shaft or eccentric bushing.To on engine lathe, process eccentric shaft or eccentric bushing, the normal method that adopts is: the offset by part to be processed calculates the thickness that the lathe chuck claw needs shimming, the method is calculated and is operated cumbersome, can't reach high accuracy class and tolerance, it only is suitable for the maintenance of single-piece, limited-run trial production and part, and is low especially for the production efficiency of producing it in batches.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency a kind of engine lathe car eccentric work piece device is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of engine lathe comprises cone with car eccentric work piece device, and binding is set on the cone, and holes for clamping is set on the binding, the parallel and conllinear not of the centre line L 2 of holes for clamping and the centre line L of cone 1.
Above-mentioned engine lathe car eccentric work piece device, described holes for clamping is provided with elastic groove and springhole, springhole and elastic groove UNICOM, the binding of flexible groove one end is provided with tightens screw.
Above-mentioned engine lathe car eccentric work piece device, described binding is arranged on the cone by attachment screw.
Above-mentioned engine lathe car eccentric work piece device, described binding is arranged on the cone by alignment pin.
Adopt technique scheme, the utility model has following advantage: during operation, distance between the holes for clamping center and the cone centre of gyration is adjusted by part to be processed is eccentric, tightened pinching screw after workpiece installs, workpiece is locked by the distortion of elastic groove on the binding and springhole.The utility model is simple in structure, and is easy to operate, significantly improved production efficiency, can produce in batches.Be fit to engine lathe turning eccentric shaft or eccentric bushing workpiece.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
The car eccentric work piece device of a kind of engine lathe as depicted in figs. 1 and 2, comprise cone 1, binding 5 is set on the cone 1, holes for clamping 6 is set on the binding 5, parallel and the conllinear not of the centre line L 2 of holes for clamping 6 and the centre line L of cone 11, holes for clamping 6 is provided with elastic groove 8 and springhole 7, springhole 7 and elastic groove 8 UNICOMs, the binding 5 of flexible groove one end is provided with tightens screw 2, binding 5 is arranged on the cone 1 by attachment screw 4 and alignment pin 3, promptly by the distance between the required processing parts eccentric distance adjustment binding and the cone centre of gyration, tighten attachment screw 4 after adjusting the position, on binding and cone, all mix pin hole, tighten behind the attachment screw and alignment pin 3 to be squeezed into the pin hole location.
Operation principle of the present utility model is as follows: this device connects by lathe spindle center sleeve inner cone.Cone 1 directly installs to auto lock in the center sleeve taper hole, and binding 5 holes for clamping diameters are by the institute's holding workpiece outside diameter of wanting design, between holes for clamping 7 centers and cone 1 centre of gyration apart from pressing part eccentric throw to be processed and deciding.Tighten pinching screw 2 after workpiece installs, workpiece is locked by the elastic groove on the binding 58 and the distortion of springhole 7.
