Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pinion gear,

Since the origin point required for post-machining of the pinion gear can be set more easily and easily, it is possible to perform the machining more quickly and precisely, thereby greatly contributing to productivity and quality improvement. .

Generally, pinion gears are manufactured by machining including Hobbing, Broaching, shaping, and milling, or by forging, casting, extrusion, powder molding,

After the basic contour is created, a variety of post-processing is performed, such as rounding or chamfering the edge of the tooth or machining the inclination angle at a portion of the tooth bottom.

1, the pinion gear 10 is provided with gear teeth 11 arranged at regular angular intervals on the outer periphery of the pinion gears 10 and between the gear teeth 11, A neck portion 14 having a small diameter of a gear portion 15 is formed on the rear side of the gear portion 15 and a neck portion 14 having a diameter smaller than that of the gear portion 15 is formed, A diameter of the neck portion and a slightly larger ring projection portion 13 are formed at one side of the collet chuck of the processing machine.

On the other hand, NC or CNC machine tools are widely used for the finishing of gears of the pinion gears. They are capable of machining a wide variety of shapes as the tool (cutting tool) moves freely in two or three dimensions according to a program inputted in the control part.

When NC or CNC machine tool is machined, the information of the program input to the control part and the shape and direction of the workpiece fixed to the collet chuck must match each other, so that effective machining can be performed precisely, quickly, automatically or semi-automatically .

For this reason, when all the machining operations are performed, it is necessary to set the "origin point" so that the information of the program inputted to the NC or CNC machine tool control section and the shape and direction of the workpiece fixed to the collet chuck of the machine are made to coincide with each other.

However, the origin setting required at the finishing of the pinion gear is different from that of the pin or shaft (axle) by automatically fixing the collet chuck to the collet chuck, and the direction and position of the gear teeth are different each time it is fixed to the collet chuck Therefore, it is very difficult to set the origin point, and it requires a lot of time.

That is, in the conventional origin setting method for finishing the pinion gear, when fixing the workpiece material gear to the collet chuck, the direction of the gear teeth formed on the pinion gear is visually confirmed, and then, Information is carried out by hand-turning to match with the information as much as possible, or the process information stored in the control section is changed by a program operation or the like. However,

Since the conventional method of setting the origin is very inferior in accuracy, the defect rate is extremely high, and it is considerably cumbersome and takes a long time. In addition, since it is impossible to carry out automatic continuous and repeated mass production itself, productivity is greatly decreased. There is a problem such as having to have.

In the present invention, unlike the prior art in which the post-machining necessary for the pinion gear A is carried out and the origin setting is performed for a very long time, the collet chuck of the machining machine is automatically guided at the moment of clamping the workpiece, Since the setting is performed, it is possible to eliminate the separate action, waste time and troubles due to the setting of the origin at the same time, and it is possible to continuously carry out the post-machining with high precision and high quality to continuously improve the quality and productivity of the product The present invention has been accomplished on the basis of providing a method and an apparatus for setting an origin point for pinion gear post processing.

According to an aspect of the present invention, there is provided a tool for fixing a pinion gear to a tool fixing collet chuck of a processing machine (such as an NC or a CNC machine) and, after the origin setting is performed, a tool (cutting tool) In a conventional method of finishing a pinion gear, when the pinion gear, which is a workpiece, is fixed to a collet chuck of a machining tool, a plurality of gear teeth, which are formed around the periphery of the pinion gear, So that the origin setting can be automatically performed by making the contact point 200 for the origin setting correspond to one or more of the origin points.

The method and apparatus for setting the origin for pinion gear post-processing according to the present invention as described above can be used for post-finishing a pinion gear (such as rounding or chamfering a corner of a tooth or machining a tilt angle on a portion below a tooth tip) A method of fixing the origin setting contact 200 to any one or more of the plurality of gear teeth formed around the periphery of the pinion gear when fixing the pinion gear as the workpiece to the collet chuck of the machining apparatus As a result, it is possible to perform the post processing more quickly, conveniently and precisely, which contributes greatly to the improvement of the quality and productivity of the pinion gear.

FIG. 4 and FIG. 5 are diagrams showing states of use according to another embodiment of the present invention

The method and apparatus for setting the origin for post-processing of the pinion gear of the present invention will be described in more detail with reference to the accompanying drawings.

That is, the present invention is carried out by fixing the pinion gear 10 to the collet chuck 110 of the machine tool for post-processing (NC or CNC machine 100, etc.) and then performing the origin setting. When the origin setting is completed, A cutting tool) is automatically or semiautomatically matched to perform post-machining,

The required origin setting after fixing the pinion gear A as the workpiece to the collet chuck 110 of the machine tool 100 for post processing is achieved by the gear teeth 11, A contact point 200 for setting an origin is brought into close contact with or contact with at least one selected from among a plurality of pubic bones 12 existing at an obtuse angle between a plurality of tooth teeth formed at constant angular intervals. Respectively.

As means for achieving the origin setting method in which the contact point for setting the origin 200 is brought into close contact with or contact with at least one selected one of the pubic teeth 12 of the pinion gear 10 as described above,

As shown in the drawing, one or more origin setting contact portions 200 can be designed to protrude around the periphery of the work fixing collet chuck 110 of the pinion gear processing machine 100,

In this case, when the pinion gear 10 is inserted into the collet chuck 100 of the processing machine 100 for finishing the pinion gear, the pinion gear 10 is fixed.

Since any one or more of the pubic teeth 12 formed on the pinion gear 10 is naturally guided to the origin setting contact portion 200 and the origin is set automatically, it is very convenient and can be one of effective means .

The grip portion 121 of the transfer device 120 for picking up the pinion gear, which can grip the pinion gear 10 as a workpiece automatically or semiautomatically and transfer it to the collet chuck 100 of the machine, It is possible to design by setting at least one origin setting contact portion 200 in the housing,

In this case, when the pinion gear 10 is automatically picked up and fixed using the transfer device 120 for picking up the pinion gear instead of fixing the pinion gear to the collet chuck by holding it with the hand,

As the direction of the gear teeth formed on the pinion gear is naturally adjusted by one or more of the origin setting contact portions 200 formed on the grip portion of the pinion gear pickup transfer device 120 and fixed to the collet chuck 100 in this state Since the origin setting can be made automatically, this can also be another effective means.

When the one or more origin setting contact portions 200 are projected to the collet chuck 110 of the pinion gear processing machine 100 as described above,

In the process of automatically or manually fixing the pinion gear to the collet chuck 110, at least one of the pubic teeth 12 between the gear teeth formed on the pinion gear is naturally guided to the origin setting contact portion 200,

The overall shape of the pinion gear, the position of the gear teeth and the origin setting can be automatically set with reference to the origin setting contact portion 200,

In particular, the origin setting contact portion 200 protruding from the collet chuck 110 may be formed by protruding very simple protrusions or fins at one edge of the front surface of the collet chuck 110, which is quite convenient.

In the case of using the transfer device 120 for pinion gear pickup, it is preferable that at least one set of origin points capable of engaging with the pubic bone 12 formed on the gear is provided at both grip portions of the transfer device 120 for picking up the pinion gear, By forming the contact portion 200,

Since the origin setting is performed automatically when picking up the pinion gear as the workpiece, the origin is automatically set by automation at all times simply by moving in the same state and fixing it to the collet chuck 110, thereby enabling efficient machining work.
