Abstract

The utility model relates to a novel tailstock for ordinary machine tools, which belongs to machine tool industry. The utility model is characterized in that a support body and a base board form sliding connection by incline planes with certain gradient; appropriate positions in the middle of the two inclined planes are respectively processed with longitudinal and transverse guide chutes; back laminating cross guide blocks are matched in the guide chutes in a sliding mode to guide the support body longitudinally and transversely; both ends of the chute of the base board are fixedly connected with the insert block of a regulating screw; the screw is regulated to cause the support body to climb along the base board, so the function of limit fine adjustment to the vertical height of the axial line of a hollow shell is additionally obtained as compared with the existing tailstock to guarantee the ideal precision of the vertical height for service life.

Description

The novel tailstock of engine lathe

The utility model relates to a kind of constructional device that changes engine lathe tailstock hollow sleeve axle center vertical height.

At present, the manufacturing technology of known engine lathe tailstock is quite ripe, but general engine lathe tailstock support body hollow sleeve axle center vertical height does not have adjustable function, in the use, because of the continuous fretting wear between tailstock base plate and bed ways makes the hollow sleeve continuous variation of high accuracy of hanging down, cause unfavorable factors such as causing difficult control machining accuracy such as operating modes such as deep hole machining.

The purpose of this utility model provides and a kind ofly the engine lathe tailstock is increased obtain the limited fine adjustment function of support body hollow sleeve axle center vertical height.

The purpose of this utility model is achieved in that its structure and operation principle as shown in drawings, the part sequence number name is called among Fig. 1: 1, tailstock support body, 2, tailstock base plate, 3, back-folded type " ten " font slider guide, 4, conventional support body vertically moves the adjusting dog screw, and 5, insert, 6, hold-down screw, 7, the support body high dog screw of regulating that hangs down, 8, graduation mark; Fig. 2 is sequence number 2 tailstock base arrangement views; Fig. 3 is sequence number 3 back-folded types " a ten " font slider guide topology view.As shown in Figure 1, the tapered plane slip that the faying face of tailstock support body and base plate is got the certain gradient of tool connects, the appropriate location respectively processes vertical in the middle of its two tapered plane, horizontal guide runner, be fitted to wherein by back-folded type " ten " font slider guide, enforcement is vertical to support body, laterally steering, the installing of base plate chute two ends is inserted and is regulated dog screw 7, adjustment screw 7 moves laterally " ten " font slider guide drive support body together and makes support body " climbing " increase or " sliding ripple " reduction along the base plate inclined-plane, can obtain the fine adjustment function of tailstock hollow sleeve axle center vertical height so easily, lock adjusting dog screw 7 and make the support body located lateral, and this moment, tailstock was only had a conventional func, as adjust adjustment screw 4 support body is vertically moved as routine, to adapt to tailstock hollow sleeve axle center and the needs of lathe spindle axle center level to coaxial or disalignment.

Owing to adopt such scheme, can be on the basis of keeping the main manufacturing process of existing tailstock and have a following advantage: 1, be beneficial to the complete machine verification adjustment of timing tailstock hollow sleeve axle center and lathe spindle axle center axiality just; 2, lathe duration of work all can be adjusted the required vertical height in tailstock hollow sleeve axle center easily at any time and compensates the wear extent of tailstock base plate.

Certainly, during the utility model practical design, support body combines the gradient on inclined-plane with base plate generally should not get too big value, makes that other is as integral layouts such as conventional locking devices in its unlikely interference support body, and the actual value of taking is generally decided by the tear-to-wear allowance in the lifelong available life of tailstock base plate.

Claims

The novel tailstock of a kind of engine lathe, it is characterized in that: the tapered plane of getting the certain gradient of tool between engine lathe tailstock support body and its base plate is slided to be connect, the appropriate location respectively processes the vertical, horizontal guide runner in the middle of two inclined-planes, the installing of base plate chute two ends is inserted and is regulated dog screw, implement the longitudinal and transverse guiding of support body by back-folded type " ten " font slider guide, adjust and regulate dog screw and make slider guide drive support body to move laterally and change the vertical height in support body hollow sleeve axle center along base plate together.
