Embodiment 1

[0013] Embodiment 1, with reference to appended Figure 1-4 .

[0014] An end face grooving device comprises a grooving frame, a grooving motor 21 installed on the grooving frame and a cutter head 22 driven by the grooving motor 21; Front and rear, left and right, and up and down displacements, a grooving knife 23 is installed on the cutterhead 22, and the spindle motor 11 and the grooving motor 21 are controlled by a synchronous device so that the angular velocity ratio of the spindle chuck 1 and the cutterhead 22 is 1:2. The grooving knife 23 is installed on the edge of the end face of the cutter head 22 relative to the spindle chuck 1 . The cross-sectional shape of the grooving knife 23 is an isosceles inverted trapezoid.

[0015] In the initial state, the grooving knife 23 is separated from the workpiece 3 to be processed. After the processing starts, as the cutterhead 22 approaches the workpiece 3 horizontally, the grooving knife 23 also begins to approach the workpiece...

Embodiment 2

[0016] Embodiment 2, with reference to appended Figure 1-4 .

[0017] Others are the same as the embodiment, except that the ratio of the angular velocity of the spindle chuck 1 to the angular velocity of the cutter head 22 is 1:4, and two evenly distributed linear grooves are cut from shallow to deep on the workpiece 3 to be processed.

Embodiment 3

[0018] Embodiment 3, with reference to appended Figure 1-5 .

[0019] Others are the same as the embodiment, except that the ratio of the angular velocity of the spindle chuck 1 to the angular velocity of the cutter head 22 is 1:6, and three evenly distributed linear grooves are cut from shallow to deep on the workpiece 3 to be processed.

[0020] According to experimental monitoring, the straightness of the grooves processed on the workpiece 3 to be processed can be controlled below 0.01mm, and the angle error between the grooves can be controlled below 0.005mm. The production frequency can reach 20 pieces / min, which is 3-4 times of the old equipment.

Abstract

The invention relates to the technical field of machining equipment, in particular to a grooving device for machining the end surface of a rotary body component by utilizing a lathe. An end surface grooving device comprises a grooving machine frame, a grooving motor which is mounted on the grooving machine frame, and a cutter disk which is driven by the grooving motor; the grooving machine frame can move forward, backward, leftward, rightward, upward and downward relative to a chuck of a main shaft of a common numerical control lathe; a grooving cutter is mounted on the cutter disk; a spindle motor and the grooving motor are controlled through a synchronizing device, so that the ratio of the angular velocity of the chuck of the main shaft to the angular velocity of the cutter disk is 1:2N, wherein N is a positive integer. Theoretically, N grooves can be formed in a workpiece to be machined; the angle between every two grooves is decided by the rotating precision of the main shaft of the lathe, and is greatly superior to that decided by a rotary dial plate. Compared with the prior art, the end surface grooving device has the advantages that the investment is reduced, the machining efficiency and the machining precision are improved by replacing a subsequent milling and turning machining process and replacing a turning and milling integrated composite machining center with a lathe in the past.

Description

technical field [0001] The invention relates to the technical field of processing equipment, in particular to a grooving device for processing the end faces of parts of a revolving body by using a lathe. Background technique [0002] Rotary parts with end face grooves have been milled with end mills using end mills with indexing discs in the past. Every time the indexing plate rotates through a certain angle, the milling cutter mills a groove of a specific shape in parallel. This kind of processing method is time-consuming and labor-intensive. If multiple grooves are to be processed, the accuracy depends on the rotation accuracy of the index plate, and the size is not easy to guarantee. Contents of the invention [0003] The purpose of the present invention is to use a lathe to process a straight line groove on the end face of a revolving body part, thereby replacing the subsequent milling process, using a lathe to replace the previous turning-milling integrated machining...
