Abstract

The utility model provides a horizontal self-centering punching tool, including chuck, position sleeve and unit head. The chuck suit is on the position sleeve to position sleeve and chuck clearance fit make the position sleeve can be for chuck horizontal slip, and in addition, the both ends of position sleeve are the stroke of step face in order to restrict the position sleeve. The power head is fixedly connected with the positioning sleeve, a central drill is arranged at the end part of the power head, and the central drill is positioned at the axis of the positioning sleeve and extends to the outside of the positioning sleeve. By adopting the structure, the workpiece, the chuck, the positioning sleeve and the center drill are ensured to be coaxial, during operation, the workpiece and the chuck are in a static state, and the center drill moves left and right along the center through hole of the chuck along with the positioning sleeve, so that the self-centering function is realized. The utility model overcomes the unstable central benchmark skew problem that brings of work piece blank surface size is showing and is improving back end sequence machining efficiency, avoids causing the work piece to scrap because of the central deviation is too big.

Description

Horizontal self-centering punching tool
Technical Field
The utility model relates to a frock technical field that punches, concretely relates to horizontal self-centering frock that punches.
Background
Major axis class work piece blank need beat central fabrication hole location before lathe machining usually, and this type of work piece length-diameter ratio is big usually, and horizontal processing is transported the clamping and is convenient, and current processing mode punches at horizontal lathe, and the two V-arrangement irons of workstation location, because blank surface size is unstable, and this kind of location mode punches central benchmark deviation greatly, increases the processing degree of difficulty of next procedure, still can lead to the work piece to scrap when surpassing the machining allowance.
SUMMERY OF THE UTILITY MODEL
In view of the above problem, an object of the utility model is to provide a horizontal self-centering frock of punching, its chuck, position sleeve and central coaxial setting of boring, during the operation, work piece and chuck are quiescent condition, and the center bores and removes along chuck center through-hole together along with the position sleeve to realized from the centering function.
In order to achieve the above purpose, the utility model discloses a technical scheme is: a horizontal self-centering punching tool comprises a chuck, a positioning sleeve and a power head; the chuck is provided with a step-shaped clamping jaw for fixing a workpiece, and a through hole for installing a positioning sleeve is formed in the center of the chuck; the positioning sleeve comprises a main body and an end cover, the main body and the end cover are in threaded connection to ensure coaxiality, and step surfaces for limiting are arranged at the tail ends of the main body and the end cover; the positioning sleeve is in clearance fit with the chuck, so that the positioning sleeve can slide left and right relative to the chuck; the power head is fixedly connected with the main body part of the positioning sleeve, a central drill is arranged at the end part of the power head, and the central drill is positioned at the axis of the positioning sleeve and extends to the outside of the positioning sleeve.
Furthermore, the number of the clamping jaws is three, and the clamping jaws are uniformly distributed on the surface of the chuck.
And the chuck is provided with a loading and unloading hole for loosening or tightening the clamping jaw.
The front end of the positioning sleeve main body is provided with internal threads, and the front end of the positioning sleeve end cover is provided with external threads.
Compared with the prior art, the beneficial effects of the utility model are that: the self-centering three-jaw chuck is used for realizing the self-centering function, overcoming the problem of center reference offset caused by unstable outer surface size of a workpiece blank, remarkably improving the subsequent processing efficiency and avoiding workpiece scrapping caused by overlarge center deviation. The power head is small in size, the slidable positioning sleeve increases the moving flexibility of the drilling power head, long-shaft workpiece blanks do not need to be moved, drilling can be carried out only by using the blanks at fixed positions in the horizontal direction, the productivity of a horizontal machine tool is saved, and an operator can operate more flexibly and conveniently.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the horizontal self-centering punching tool comprises a chuck 1, a locating sleeve 2 and a power head 3. The chuck has step-like jaws 6 for fixing a workpiece 7, and a through hole for mounting a positioning sleeve is provided at the center of the chuck. The locating sleeve comprises a main body and an end cover 4, wherein the main body and the end cover are in threaded connection to ensure coaxiality, and step surfaces for limiting are arranged at the tail ends of the main body and the end cover. Position sleeve and chuck clearance fit for the position sleeve can be for chuck horizontal slip, specific: the main body part of the positioning sleeve penetrates through the center hole of the chuck, then the end cover is screwed on to complete the assembly of the chuck and the positioning sleeve, and the stroke of the positioning sleeve is limited by the step surfaces on the two sides of the positioning sleeve. The power head is fixedly connected with the main body part of the positioning sleeve, a central drill 8 is arranged at the end part of the power head, and the central drill is positioned at the axis of the positioning sleeve and extends to the outside of the positioning sleeve.
In addition, the jack catch has three, evenly arranges at the surface of chuck. The chuck is provided with a loading and unloading 5 hole for loosening or tightening the clamping jaws. Before clamping, a workpiece is fixed, then the clamping jaws are loosened by rotating the loading and unloading holes anticlockwise, the chuck is moved to enable the left end face of the workpiece to be attached to the step faces of the clamping jaws, the loading and unloading holes are rotated clockwise, the three clamping jaws are synchronously tightened and clamp the outer circular face of the workpiece, so that the workpiece, the chuck, the positioning sleeve and the center drill are coaxial, and centering and clamping actions are completed. At the moment, the three-jaw chuck is arranged on the right side of the outer circular surface of the positioning sleeve, and the center drill is not in contact with the end face of the workpiece. And starting the power head to drive the central drill to rotate, manually pushing the power head and the positioning sleeve to slide rightwards along the central through hole surface of the chuck synchronously, contacting the end surface of the workpiece by the central drill to start punching, manually moving the power head leftwards after the set depth to enable the central drill to withdraw from the end surface of the workpiece, anticlockwise rotating the loading and unloading hole to loosen the fixed jaw, and finishing the punching operation process.
In this embodiment, for the convenience of assembly, be equipped with the internal thread at the front end of position sleeve main part, the front end of position sleeve end cover is equipped with the external screw thread, and the two carries out screw-thread fit and connects.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention is included in the protection scope of the present invention.
