Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments thereof.
As shown in fig. 3, a positioning tool for machining a gear shaft lockstitch groove comprises a fixing body and a positioning body, wherein the fixing body is fixed on a static dial 21, the positioning body is fixed on a workpiece 90, the fixing body comprises a fixing seat 50 and a positioning plate 52, the fixing seat 50 is fixed on the static dial 21, two hinge plates 51 are fixed on the fixing seat 50, and the positioning plate 52 is hinged between the two hinge plates 51.
As shown in fig. 6-7, the positioning body includes a sleeve 60 with two through ends, the wall of the sleeve 60 is provided with a screw hole 61, the screw hole 61 is in threaded fit with a bolt 64, a fin plate 62 is fixed in the radial direction of the sleeve 60, the outer end of the fin plate 62 is provided with a positioning groove 63, the two positioning grooves 63 are symmetrical along the axis of the sleeve 60, and when the positioning plate 52 is located in the positioning groove 63, the two side surfaces of the positioning plate 52 are in surface contact with the two groove walls of the positioning groove 63.
For convenience of operation, the bolts 64 are thumb bolts or T-bolts (FIG. 7 is a T-bolt). Thus, the bolt can be directly screwed by hand without the aid of tools.
For the sake of firmness, the two fins 62 are connected by the connecting plate 66, the two fins 62 and the connecting plate 66 are integrally formed, the connecting plate 66 is provided with a through hole, the sleeve 60 penetrates through the through hole, and the connecting plate 66 and the sleeve 60 are fixedly welded.
The working principle is as follows:
when in use, the positioning is firstly carried out, which comprises the following steps:
referring to fig. 5, the bolts 64 are loosened, the sleeve 60 is fitted around the large end of the workpiece 90, and the bolts 64 are tightened to fix the workpiece 90 and the sleeve 60 together.
As shown in fig. 4-5, the movable dial 33 and the front center 34 are integrally moved leftward to make the space between the front center 34 and the rear center 22 sufficiently large, and at the same time, the workpiece 90 and the sleeve 60 are held by hand to be positioned at a high position by rotating the dial 52 clockwise, and the right end of the workpiece 90 is abutted against the rear center 22, and then the workpiece 90 is rotated to make one of the positioning grooves 63 (hereinafter referred to as a first positioning groove) uppermost, and at this time, the dial 52 is rotated counterclockwise to be clamped in the first positioning groove, and finally, the movable dial 33 and the front center 34 are integrally moved rightward to fix the workpiece between the front center 34 and the rear center 22.
Thus, the positioning is finished at one time.
At this time, the first lockstitch groove may be machined, and the lockstitch groove is not described in detail in view of the prior art.
After first lockstitch groove processing finishes, carry out the secondary location, include:
as shown in fig. 4 to 5, the dial 33 and the center 34 are rotated clockwise to be located at the high position, the workpiece 90 is rotated to be held by a hand and rotated 180 degrees, the other positioning groove 63 (hereinafter referred to as a second positioning groove) is located at the top, the dial 52 is rotated counterclockwise to be caught in the second positioning groove, and finally, the dial 33 and the center 34 are moved rightward to fix the workpiece between the center 34 and the center 22.
Thus, the secondary positioning is finished.
At this time, the second lockstitch groove can be machined, and the lockstitch groove is processed in the prior art, and is not described in detail.
Because the two positioning slots 63 are symmetrically arranged along the axis of the sleeve 60, the two lockrand slots machined in this way are also symmetrically arranged along the axis of the sleeve 60 (also the axis of the workpiece 90), and are very accurate.
It should be noted that if the shaft diameter of the gear shaft does not match the inner diameter of the sleeve 60, the sleeve 60 needs to be replaced for proper positioning.
See the prior art for additional details.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
