Knurling equipment with vertical cutting feed function

Abstract

The invention provides knurling equipment with a vertical cutting feed function. The knurling equipment comprises a frame (1). A rotating device is arranged at the lower end of the frame, a cutting feed device is arranged at the upper end of the frame, a knurling tool (2) is arranged on the cutting feed device, the cutting feed device comprises a cylinder (5), the cylinder is vertically mounted at the upper end of the frame (1), a pressure head assembly (3) is connected with a piston end of the cylinder (5), the knurling tool (2) is arranged at the lower end of the pressure head assembly (3), the rotating device is provide with a rotary shaft assembly (4) for clamping workpieces, and the rotary assembly (4) and the pressure head assembly (3) are coaxial with each other and are positioned on the same vertical plane. The knurling equipment with the vertical cutting feed function has the advantages that the vertical cutting feed function can be realized, the cutting feed quantity can be controlled by the cylinder, and the position and the feed quantity of the knurling tool can be preset, so that operators only need to fetch a sleeve and start the equipment to effectively guarantee the consistency of the knurling quality; the cylinder only exerts low down force to drive the pressure head assembly, and accordingly the knurling tool is not easy to abrade and does not need to be frequently replaced.

Description

technical field [0001] The invention relates to a knurling device, in particular to a knurling device adopting a vertical feeding method. [0002] Background technique [0003] Knurling is a mechanical process of rolling patterns on the handles of metal products or other working surfaces, mainly for anti-slip. The end of the automobile stabilizer bar sometimes needs to be welded with a sleeve used to protect the stabilizer bar. In order to increase the friction on the outer surface of the sleeve, the two ends of the sleeve should be processed with straight grain knurling, which is a commonly used processing method in the industry. Knurling is performed by using a lathe, that is, the casing is clamped on the main shaft of the lathe, and the knurling wheel is fed into the tool to realize knurling. [0004] This knurling method has the following disadvantages during knurling: the casing is easy to loosen when it is clamped, and the casing will vibrate when the spindle rotate...

Problems solved by technology

[0004]This kind of knurling method has the following disadvantages during knurling: the sleeve is easy to loosen when it is clamped, and the sleeve will vibrate when the main shaft rotates, making the roll out The shape is irregular, which affects the consistency of product quality; the taper and feed rate are not easy to adjust when the knife is fed, and the twill and knurling depths do not meet the requirements; because the knurling is horizontally fed, the knurling knife is easy to wear , affecting the service life

In summary, the scrap rate of using lathe knurling is very high, which is not conducive to the guarantee of casing quality consistency and the control of production costs
