Abstract
The invention discloses an ejection device of a numerically controlled lathe, comprising a mandrel (1), a spring (2), a positioning body (3), a screw nut (4), a stop pin (5), a spring (6) and a screw nut (8), wherein the spring (2) is arranged on the mandrel (1), the positioning body (3) is fixed on the mandrel (1) by a screw nut (7), and the stop pin (5) is fixed on the positioning body (3) by the screw nut (4).The mechanical hydraulic pressure ejection method is applied to the ejection device of the numerically controlled lathe, so that end face parallel degree error of the processed workpiece caused by simultaneous motion of clamping of the external diameter or inner diameter of a clamping jaw of a fixture and positioning datum plane is eliminated and workpiece machining accuracy is improved. The device effectively controls product quality and solves the problem of workpiece end face parallel degree error caused by positioning error of the numerically controlled lathe.
Description
Technical field
The present invention relates to field of machining, it is in the lathe in machining process, eliminates because of anchor clamps radially clamp when moving simultaneously with axial location, causes processing a kind of device of the overproof method of faces parallel, relates in particular to a kind of numerically controlled lathe Lifting Device.
Background technology
Numerically controlled lathe has been widely used in bearing industry, can be used for soft car or hard car, no matter soft car or hard car, and during material loading, external diameter or internal diameter clamp to move simultaneously with the location datum level workpiece are clamped.When this clamping means are had relatively high expectations in the workpiece depth of parallelism, the depth of parallelism of the processed end face of workpiece but is difficult to reach specification requirement, especially hard turner part end face, its depth of parallelism generally requires when 0.02mm is following the just more difficult requirement that reaches, when its main cause is manual material loading, the external diameter of anchor clamps or internal diameter jaw move simultaneously with the location datum level workpiece are clamped, like this, workpiece location benchmark can not fully contact with the locating surface of anchor clamps, there is certain gradient, therefore, cause the surface of part to be processed and location datum level existence also to have corresponding gradient, Here it is workpiece to be machined end face and datum level depth of parallelism basic reason rambunctious.
Summary of the invention
The purpose of this invention is to provide a kind of the elimination and move the faces parallel error of the workpiece to be machined that causes simultaneously, improve the numerically controlled lathe Lifting Device of workpiece machining accuracy because of chuck jaws external diameter or internal diameter clamp with the location datum level.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of numerically controlled lathe Lifting Device, comprise axle (1), spring (2), positioning body (3), nut (4), spacer pin (5), spring (6) and nut (7), spring (2) is installed on the axle (1), positioning body (3) is fixed on the axle (1) by nut (7), and spacer pin (5) is fixed on the positioning body (3) by nut (4).
Described spacer pin (5) is 120 ° of circle distribution in positioning body (3).
Numerically controlled lathe Lifting Device of the present invention, solved because of chuck jaws external diameter or internal diameter clamp with the location datum level and moved the parallelism error of the workpiece to be machined end face that causes and location datum level simultaneously, device is to adopt mechanical-hydraulic liftout method, elimination is moved the faces parallel error of the workpiece to be machined that will cause simultaneously because of chuck jaws external diameter or internal diameter clamp with the location datum level, improve the workpiece machining accuracy, product quality has been controlled in succeeding in developing of this device effectively, has solved the overproof problem of the workpiece end face depth of parallelism that numerically controlled lathe causes because of position error.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is a numerically controlled lathe Lifting Device structural representation of the present invention.
Among the figure: 1, axle; 2, spring; 3, positioning body; 4, nut; 5, spacer pin; 6, spring; 7, nut.
The specific embodiment
As shown in Figure 1; numerically controlled lathe Lifting Device of the present invention; mainly by axle 1; spring 2; positioning body 3; nut 4; spacer pin 5; spring 6; nut 7; constitute; axle 1 is a device main body; play supporting role; positioning body 3 can axially move on axle 1; carry out axial limiting by nut 7 and spring 2; spacer pin 5 is positioned at positioning body and is 120 ° of circle distribution (as Fig. 2); each spacer pin is by spring 6 controls; can radially move; workpiece is fixed on the three-point fix pin; given figure car controlling bed Lifting Device; utilize numerically controlled lathe hydraulic pressure tailstock centre system; the research feeding; hold out against; make jaw in clamping process; guarantee that fully the workpiece to be machined locating surface fully contacts with the locating surface of anchor clamps; Lifting Device is fixed in axle 1 on the position of tailstock centre; positioning body 3 cooperates with axle 1; by nut 7 positioning body 3 is locked on the axle 1; spacer pin 5 is fixed on the positioning body 3 by nut 4; spacer pin 5 is spacing by spring 6 in positioning body 3 simultaneously, and when the workpiece material loading held out against, positioning body 3 played elasticity by spring 2 and holds out against effect; with the axial precision of protection main shaft; adding man-hour, workpiece is being contained in the front end of Lifting Device, by the hydraulic pressure feeding; the workpiece flexibility is held out against at the location of anchor clamps end face, and jaw just can guarantee when clamping that the workpiece datum end face fully contacts with the anchor clamps locating surface and do not have a tilt quantity.
During the work of this device, by HYDRAULIC CONTROL SYSTEM, clamping workpiece is positioned on the positioning body 3 of axle 1 front end and with positioning body 3 locating surfaces and is close to, axial feed by axle 1 is sent into workpiece in the anchor clamps, and workpiece end face is contacted with the anchor clamps locating surface, simultaneously, positioning body 3 is under the elastic force effect of spring 2, the end face that guarantees workpiece fully contacts with the locating surface of anchor clamps, and at this moment, anchor clamps are done and radially clamped action, behind the clamp workpiece, Lifting Device withdraws from, and machining begins, and existing is that example describes this device with 3506/76R outer ring flange product, before using this device: this product outer ring flange rib of processing on CAK6150 equipment, the material loading clamping process is placed on lasso in the anchor clamps by the operator, with hand steered lasso to clamp, the product rib depth of parallelism 0.04-0.06mm that in this way processes; This product is after adopting this device, eliminated the gradient of artificial ring face and anchor clamps locating surface, and guaranteed that fully lasso is in the clamp process, ring face fully contacts with the axial locating surface of anchor clamps all the time and does not have or the gap generation, and the depth of parallelism of this product rib effectively is controlled at below the 0.02mm.
