Description

Gear shaving cutter jig tool

Technical Field

The utility model relates to an instrument processing field, it is specific, relate to a gear shaving cutter jig frock.

Background

The prior art is that scribing is carried out before the lightening holes of the gear shaving cutter are drilled, then a punch is used for punching the scribing position, and then 12 lightening holes are drilled on a drilling machine. As the number of shaving cutters increases, the lightening holes of each shaving cutter need to be scribed, which greatly reduces the production efficiency.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a gear shaving cutter jig frock has saved every gear shaving cutter and all needs the time of drawing a line, has improved machining efficiency.

The utility model aims at realizing through the following technical scheme:

the gear shaving cutter drill jig tool comprises a circular drill jig plate, wherein a spindle hole is formed in the middle of the drill jig plate, a plurality of jig plate holes are formed in the surface of the drill jig plate in the circumferential direction, the distance from the circle center of each jig plate hole to the circle center of the drill jig plate is equal, and the gear shaving cutter drill jig tool further comprises a spindle body matched with the spindle hole.

Further, the mandrel body comprises a fixed section, a connecting section, a limiting section and a grabbing section which are connected in sequence.

Further, one end of the connecting section, which is close to the fixing section, is provided with a chamfer part with a trapezoidal structure.

Further, the diameter of the fixed section is smaller than that of the connecting section, and the diameter of the connecting section is smaller than that of the limiting section.

And the spacers are arranged between the drilling template and the workpiece to be machined and correspond to the template holes.

Further, the chamfer angle from the surface edge to the end face of the jig plate is 45 °.

Further, the diameter of the template hole is 5 mm.

The utility model has the advantages that:

the utility model discloses a designed bushing plate and replaced the mode of conventional marking off, greatly improved production efficiency, simultaneously through the design of mandrel, increased the bushing plate and the stability of treating the being connected of machined part. Therefore, the method has better practicability and is suitable for being popularized in a large amount in the market.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the present invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof.

Drawings

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings, in which:

FIG. 1 is a front and left view of a bushing plate;

FIG. 2 is a schematic view of a mandrel pattern.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for purposes of illustration only and are not intended to limit the scope of the present invention.

The embodiment provides a gear shaving cutter drill jig tool, as shown in fig. 1, which includes a circular drill plate 1, wherein a chamfer from the surface edge to the end face of the drill plate 1 is 45 degrees, a spindle hole 11 is formed in the middle of the drill plate 1, a plurality of template holes 12 are circumferentially formed in the surface of the drill plate 1, the diameter of each template hole 12 is 5mm, the distance from the circle center of each template hole 12 to the circle center of the drill plate 1 is equal, the template holes 12 are used for assisting a drill to drill lightening holes on a gear shaving cutter to be machined, as shown in fig. 2, the gear shaving cutter drill jig tool further includes a spindle body 2 adapted to the spindle hole 12, the spindle body 2 is used for connecting the drill plate 1 and the gear shaving cutter to be machined, the spindle body 2 includes a fixing section 21, a connecting section 22, a limiting section 23 and a grabbing section 24 which are sequentially connected, wherein the diameter of the fixing section 21 is smaller than that of the connecting section 22, the diameter of the connecting section 22 is smaller than that of the limiting section 23, the fixing section 21 is used for, the connecting section 22 is used for connecting a gear shaving cutter to be machined with the drill plate 1, the limiting section 23 is used for limiting axial movement of the gear shaving cutter to be machined with the drill plate 1, the grabbing section 24 is used for a worker or automatic equipment to grab the core shaft body 2, and for convenience of connection, one end, close to the fixing section 21, of the connecting section 22 is provided with a chamfer angle portion of a trapezoidal structure, and the chamfer angle is 15 degrees.

Preferably, the drilling jig further comprises the same number of gaskets as the number of the template holes, and the gaskets are arranged between the drilling jig plate 1 and the workpiece to be machined and correspond to the positions of the template holes 12. The spacer is provided for adjusting the relative height of the drill plate 1 and the workpiece to be machined in the production process, and when the relative height is proper, the spacer is not needed.

The utility model discloses an embodiment is: and (3) mounting the gear shaving cutter to be processed on the drilling template 1, drilling the centers of all template holes 12 by using a drill bit with the diameter of phi 5 after the gear shaving cutter is fixed, and then taking down the drilling template 1 to drill lightening holes.

Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
