Description

Tailstock of numerically controlled lathe

Technical Field

The utility model relates to a lathe especially relates to numerical control lathe's tailstock.

Background

When the numerical control lathe is used for processing shaft workpieces, the workpieces need to be clamped tightly through the centers at the two ends (the workpieces are clamped through the front center arranged at the main shaft and the rear center arranged at the central spindle of the tailstock), then the machining operation is carried out, and in the clamping process, the workpieces are in a suspended state, so that the clamping convenience is poor. Therefore, a tailstock is needed to be designed to facilitate clamping of shaft workpieces, and a better technical scheme is not found in the prior art.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above problem, providing a tailstock of numerical control lathe, axle type work piece clamping is comparatively convenient.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a tailstock of numerical control lathe, is including setting up the dabber on the tailstock, the dabber tip is used for installing the back top, its characterized in that, the dabber is close to tip department and sets up the bulge loop, the bulge loop below sets up the auxiliary stay subassembly, the auxiliary stay subassembly is including being the support of "one" style of calligraphy, the support right-hand member connects in the bulge loop, and the left end connects in the backup pad.

Further, the backup pad is the rectangle, and the upside sets up holds in the palm a mouth, the support left end sets up the screw thread post, the backup pad is worn on the screw thread post to it is fixed through nut cooperation spacing ring, and the spacing ring setting is at the support left end.

Further, the support plate is made of stainless steel.

Furthermore, the support has the right section that is located the right side and is located the left section, right side section left part has the blind hole, and the blind hole bottom sets up the spring, and the spring left end is connected in the apron, the left section is installed in the blind hole to fasten through the fastening screw on the blind hole.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses set up the auxiliary stay subassembly in the hold assembly below, the centre gripping work piece in-process plays auxiliary stay (supporting) effect, has improved the convenience of centre gripping (clamping) in-process.

Detailed Description

Example 1: referring to fig. 1 and 2, the tailstock of the numerically controlled lathe comprises a mandrel 11 (sleeve) arranged on the tailstock 1, wherein the end of the mandrel 11 is used for mounting a rear center 13, a convex ring 21 is arranged at the position, close to the end, of the mandrel 11, an auxiliary support assembly is arranged below the convex ring 21, the auxiliary support assembly comprises a linear support 31, the right end of the support 31 is connected with the convex ring 21, and the left end of the support 31 is connected with a support plate 35.

In this embodiment, the supporting plate 35 is rectangular, the upper side of the supporting plate is provided with a supporting opening 35a, the left end of the support 31 is provided with a threaded column 32, the supporting plate 35 penetrates through the threaded column 32 and is fixed by a nut 34 matched with a limiting ring 33, and the limiting ring 33 is arranged at the left end of the support.

In this embodiment, the supporting plate 35 is made of stainless steel.

The rear center in this embodiment is generally a live center.

In the process of clamping shaft workpieces, a worker takes up the workpieces, and aligns the left end clamping position of the workpieces to the front center, the right end of the workpieces is arranged in (placed on) the supporting port, the supporting plate is used for supporting the workpieces in an auxiliary mode, so that the workpiece is taken up, the arm clamping process is labor-saving, the rear center moves towards the left side, the supporting plate synchronously moves towards the left side (the workpieces can slide relative to the supporting plate), when the rear center is close to the right end of the workpieces, the right end of the workpieces is raised (raised slightly), the workpiece right end clamping position is aligned to the rear center, and clamping is completed. After the front center and the rear center finish clamping, the shaft workpiece is in a suspended state relative to the supporting opening, so that the supporting plate can not influence the processing process of the shaft workpiece.

It should be emphasized that the depth of the support opening is only an example, and can be adjusted according to the size of the shaft workpiece, the support can be realized in the clamping process, and the workpiece processing is not affected after the clamping is finished. Additionally, the shape of the tray opening includes, but is not limited to, the patterns listed in the figures.

For the sake of brevity, the remaining components of the tailstock are not described herein and reference is made to the prior art.

Example 2: the basic structure is the same as that of embodiment 1, except that, referring to fig. 3, the bracket 31 has a right section 31a on the right side and a left section 31e on the left side, the left part of the right section 31a has a blind hole, a spring 31b is arranged at the bottom of the blind hole, the left end of the spring 31b is connected to a cover plate 31c, and the left section 31e is installed in the blind hole and fastened by a fastening screw 31d on the blind hole.

The cover plate is positioned at the opening of the blind hole in a natural state under the action of the spring and is used for plugging the blind hole and avoiding foreign matters from entering. After the left section of the bracket is placed in, the cover plate is pressed into the blind hole, and when the length is proper, the left section can be locked through the fastening screw. Through the mode, the length of the support can be adjusted, and convenience in use and installation is improved.

Above only do the preferred embodiment of the present invention, the protection scope of the present invention is not limited to the above embodiment, all belong to the technical scheme of the present invention all belong to the protection scope of the present invention. For those skilled in the art, several modifications can be made without departing from the principle of the present invention, and such modifications should also be considered as the protection scope of the present invention.
