Detailed ways

In order to further elaborate the technical means and effects that the utility model takes for reaching the intended purpose of the invention, below in conjunction with the accompanying drawings and preferred embodiments, its specific implementation, structure, Features and their functions are described in detail below.

Please refer to Fig. 2 and Fig. 3, a grinding machine of a rod-shaped cutter of the present invention comprises:

A body 10, the top of the body 10 is provided with a grinding machine 20 and a guiding machine 30;

One end of the grinder 20 is provided with a motor 21 , and the other end is provided with a circular grinding disc 22 , and the motor 21 can drive the grinding disc 22 to rotate.

The guide 30 is located on the outside of the grinding disc 22, and further includes a chuck 31, the chuck 31 is axially corresponding to the outer circumference of the grinding disc 22, and can clamp a rod-shaped cutter 32 (such as a drill bit or a hob ), so that the cutting grooves on the peripheral surface of the tool 32 can correspond to the grinding disc 22, a connecting rod 33 is arranged laterally on the side of the chuck 31, and a pair of guide rods 34 are arranged axially backward on the connecting rod 33, and the pair The guide rod 34 abuts against the front end of a cam 35 horizontally. The front end of the cam 35 is a curved surface with different thicknesses at the front and back, and the outer peripheral surface of the cam 35 is made of concave and convex curves. Refer to FIG. 4 again.

A casing 36, the inside of the casing 36 is provided with a transmission gear (not shown), and the transmission gear is rotated by a rotating rod 37 at the rear of the casing 36 to drive the cam 35 to rotate.

A push rod 38, the push rod 38 is composed of a lower rod 381 and an upper rod 382 pivotally connected, the lower end of the lower rod 381 is pivotally connected to the body 10, and the upper end of the upper rod 382 is supported on the cam 35 the lower edge.

With the above-mentioned structure, when the rotating rod 37 is rotated by hand, the cam 35 can be driven to rotate through the transmission of the internal transmission gear of the casing 36. Since the thickness of the front end surface of the cam 35 is different, the The pair of guide rods 34 on the front end surface of the cam 35 move back and forth, and the chuck 31 can be driven synchronously via the connecting rod 33, and the chuck 31 drives the tool 32 to move back and forth.

In addition, the peripheral wall of the cam 35 is made of concave-convex curves. When the cam 35 rotates, it will be pushed up by the lower push rod 38, so that the cam 35 will move up when it protrudes from the peripheral wall and is pushed up by the push rod 38. 35 is concave curve and contacts with this ejector rod 38 then cam 35 is to be displaced downwards, so this collet 31 can produce up and down except the action that can produce forward and backward displacement.

Therefore, when grinding a drill bit or a hob, the chuck 31 rotates and stretches out according to the edge of a helical groove on the outer peripheral wall of the tool 32, so that the rotating grinding disc 22 is ground along the helical edge. profit.

What is important is that the utility model drives the chuck 31 to move in a helical direction, which is achieved only by the shape design of the cam 35, and the structure is quite simple to reduce the cost.

The above are only preferred embodiments of the present utility model, and do not limit the utility model in any form. Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model. Any Those skilled in the art, without departing from the scope of the technical solution of the present utility model, can use the structure and technical content disclosed above to make some changes or modify equivalent embodiments with equivalent changes, but all without departing from the utility model The content of the new technical solution, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model still belong to the scope of the technical solution of the utility model.
