Abstract
The utility model discloses a positioner is used in processing of jackshaft gear shaping, including the mount pad of in-band conical surface, expand cover and gland nut, the mount pad passes through the bolt fastening on the lathe workstation, expand the suit and establish in the hole of mount pad, expand be equipped with on the excircle of cover that expands with mount pad interior conical surface assorted toper boss, gland nut establishes the front end at the mount pad with threaded connection's form cover, and the shaping has annular gland face and expands to sheathe in the shoulder of toper boss and contact on the interior circle of gland nut. The utility model has the advantages of being simple in structure and convenient in operation, add man-hour, pass the axial region of work piece expand the suit and go into the mount pad hole, then rotate gland nut and utilize to compress tightly the terminal surface and promote to expand the cover and move backward, expand the cover and under the effect of mount pad internal conical surface pressure, contract rapidly and press from both sides tight work piece, make the work piece firmly fix a position on the lathe workstation, guaranteed going on smoothly of gear shaping processing.
Description
Technical Field
The utility model relates to a gear machining makes technical field, and more specifically says, especially relates to a positioner is used in processing of jackshaft gear shaping.
Background
In the gear processing and manufacturing industry, gear shaping is to process the tooth surfaces of internal and external gears or racks and the like by a gear shaping cutter according to a generating method or a forming method, and the gear shaping can process straight teeth and helical teeth. When the intermediate shaft gear is subjected to gear shaping, a three-jaw chuck is adopted to clamp a workpiece on a machine tool workbench for machining in the traditional machining method, but the three-jaw chuck is adopted to clamp the workpiece, so that the defects of unstable clamping and low positioning precision exist, and the machining efficiency and the machining quality are influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to the not enough of above-mentioned prior art, provide a convenient operation and fix a position firm positioner is used in processing of countershaft gear shaping.
In order to achieve the above object, the utility model adopts the following technical scheme: a positioning device for processing gear shaping of an intermediate shaft gear comprises a mounting seat with an inner conical surface, an expansion sleeve and a compression nut, wherein the mounting seat is fixed on a machine tool workbench through bolts, the expansion sleeve is arranged in an inner hole of the mounting seat, a conical boss matched with an inner conical surface of the mounting seat is arranged on an outer circle of the expansion sleeve, the compression nut is sleeved at the front end of the mounting seat in a threaded connection mode, and an annular compression end surface is formed on an inner circle of the compression nut and contacts with a shoulder of the conical boss on the expansion sleeve.
The utility model has the advantages of being simple in structure and convenient in operation, add man-hour, pass the axial region of work piece expand the suit and go into the mount pad hole, then rotate gland nut and utilize to compress tightly the terminal surface and promote to expand the cover and move backward, expand the cover and under the effect of mount pad internal conical surface pressure, contract rapidly and press from both sides tight work piece, make the work piece firmly fix a position on the lathe workstation, guaranteed going on smoothly of gear shaping processing.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-mounting a base; 2-expanding sleeve; 21-a tapered boss; 3-pressing the nut; 31-pressing the end face; 4-the workpiece.
Detailed Description
The present invention will be described in further detail with reference to the following examples, which are not intended to limit the invention.
As shown in fig. 1, the utility model provides a pair of positioner is used in processing of jackshaft gear shaping, including mount pad 1, the cover 2 and the gland nut 3 that expand of in-band conical surface, mount pad 1 passes through the bolt fastening on the lathe workstation, expand the cover 2 and install in mount pad 1's hole, expand be equipped with on the excircle of cover 2 with mount pad 1 interior conical surface assorted toper boss 21, gland nut 3 establishes the front end at mount pad 1 with threaded connection's form cover, and the shaping has annular pressure terminal surface 31 and expands the shoulder that overlaps 2 upper cone boss 21 of expanding to contact on gland nut 3's the interior circle.
When the gear shaping machine is used, the shaft part of a workpiece 4 (a middle shaft gear) penetrates through the expansion sleeve 2 and is arranged in an inner hole of the mounting seat 1, then the compression nut 3 is rotated to push the expansion sleeve 2 to move backwards by utilizing the compression end face 31, the expansion sleeve 2 is rapidly contracted and clamped with the workpiece 4 under the action of the pressure of the inner conical surface of the mounting seat 1, the gear shaping machine is started to perform gear shaping processing on the workpiece 4, and after the processing is finished, the compression nut 3 is loosened to take down the workpiece 4, so that the operation is simple and convenient.
