Description

Adjustable chamfering knife

technical field

The utility model relates to the technical field of turning and milling cutters, in particular to an adjustable chamfering cutter.

Background technique

Chamfering operation is a common processing content when performing metal cutting on a lathe. However, the number of chamfering angles often varies with workpieces. Generally, the degree of chamfering is 5°~120°, which requires frequent replacement of chamfering knives with various angles. Processing time, low production efficiency.

Utility model content

The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art, to provide an adjustable chamfering knife, which can be properly adjusted within a certain range according to processing requirements.

The technical solution adopted by the utility model to solve its technical problems is: an adjustable chamfering knife, including a blade, a circular head and a knife body, the blade is arranged on the outside of the top surface of the circular head and passes through the The cylindrical pin is fixed, and the center of the circular head is provided with a screw hole, and the circular head is embedded in the head step of the cutter body, and the circular head is fixedly connected with the cutter body through a nut, so The top surface of the circular head is provided with scale lines showing angles.

Further, a waist-shaped groove is provided on the inner side of the circular head, and auxiliary screws are arranged in the waist-shaped groove.

The beneficial effects of the utility model are as follows:

The utility model has the advantages of simple structure and wide application range, and can be applied to chamfering at various angles, thereby expanding the processing applicability of the tool; it can be chamfering at various angles, reducing the number of tools, and reducing the number of tools, tool setting, etc. Auxiliary time, improving production efficiency.

detailed description

In order to make the content of the utility model more clearly understood, the utility model will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

The adjustable chamfering knife as shown in Figure 1 and Figure 2 includes a blade 1, a circular head 2 and a cutter body 4, the blade 1 is arranged on the outside of the top surface of the circular head 2 and is fixed by a cylindrical pin, and the circular head The diameter of the part 2 is 30mm, and the center of the round head 2 is provided with an M8 screw hole, the round head 2 is embedded in the head step of the cutter body 1, and the round head 2 is fixedly connected with the cutter body 4 through the nut 5 , The top surface of the round head 2 is provided with a scale line showing the angle, which gradually increases from 5°. An auxiliary screw 3 of M5X25 is additionally housed on the circular head 2, which plays an auxiliary clamping role. In order to facilitate the adjustment of the angle of the circular head 2 and make proper rotation, a waist-shaped groove 6 is milled out in its inner side according to the scale range.

When in use, the auxiliary screw 3 and the nut 5 can be loosened at the same time, and the angle can be quickly adjusted according to the processing requirements.

The specific embodiments described above have further described the purpose, technical solutions and beneficial effects of the present utility model in detail. It should be understood that the above descriptions are only specific embodiments of the present utility model and are not intended to limit the present invention. For the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
