Abstract

The utility model relates to a square shaft for an ATC tool magazine, which comprises a shaft body with a square section and a mounting seat, wherein a groove for storing lubricating oil is formed in the peripheral surface of the shaft body, an oil drainage hole penetrating through the mounting seat is formed in the center of the shaft body, and an oil drainage hole communicated with the oil drainage hole is formed in the mounting seat in the radial direction. According to the utility model, the oil drain hole penetrating through the mounting seat is formed in the center of the shaft body, so that lubricating oil can flow into the oil drain hole from the upper end surface of the shaft body when the tool changing device is used, and vertically falls down along the oil drain hole, is discharged from the oil drain hole, is filtered and then enters the groove again, so that on the premise of ensuring the sliding effect between the square shaft and the output shaft, the clamping stagnation phenomenon caused by the fact that impurities generated by sliding friction between the square shaft and the output shaft enter the lubricating oil can be effectively prevented, and the accuracy of tool changing action is ensured.

Description

Square shaft for ATC tool magazine

Technical Field

The utility model relates to the technical field of numerical control machining, in particular to a square shaft for an ATC tool magazine.

Background

In the automatic tool changing system matched with the numerical control machine tool in machining, power is transmitted through a square shaft through rotation of a turret shaft to drive a force output shaft to rotate, and finally, a tool arm installed on the force output shaft is driven to realize tool changing through stretching and rotating motion of the force output shaft. Wherein the square hole cooperation of square axle and output shaft is connected and transmission power and relative slip, for the sliding property who improves between square axle and the output shaft, offer the slot that holds lubricating oil in the square axle periphery, nevertheless in the in-service use in-process, because lubricating oil is in all the time and lubricates between square axle and the output shaft, lubricating oil is sneaked into very easily to the impurity that square axle and output shaft relative slip friction produced, and the jamming phenomenon appears when causing the output shaft to remove, the unable smooth and easy slip accomplishes the tool changing.

Disclosure of Invention

The technical problem to be solved by the utility model is as follows: in order to overcome the defects in the prior art, the utility model provides a square shaft for an ATC tool magazine, which ensures the smooth sliding of a force output shaft relative to the square shaft and improves the accuracy of tool changing.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides an used square shaft of ATC tool magazine, includes that the cross-section is the axis body and the mount pad of square, axis body peripheral surface set up the slot of storage lubricating oil, the axis body center is seted up the draining hole that link up the mount pad, is located the oil drain hole of radially seting up intercommunication draining hole on the mount pad.

Specifically, the grooves extend around the outer circumferential surface of the shaft body along the axial direction, so that more lubricating oil can be in contact with the square holes of the output shaft, and the lubricating effect is improved.

Furthermore, the mounting seat comprises a column body and a mounting flange, the column body and the shaft body are of an integrated structure, the mounting flange is fixedly connected with the column body, and the oil drainage hole penetrates through the shaft body and the column body.

Preferably, two centrosymmetric oil discharge holes are radially formed in the cylinder body below the mounting flange, so that lubricating oil accumulated in the oil discharge holes can be quickly discharged.

The utility model has the beneficial effects that: according to the utility model, the oil drain hole penetrating through the mounting seat is formed in the center of the shaft body, so that lubricating oil can flow into the oil drain hole from the upper end surface of the shaft body when the tool changing device is used, and vertically falls down along the oil drain hole, is discharged from the oil drain hole, is filtered and then enters the groove again, so that on the premise of ensuring the sliding effect between the square shaft and the output shaft, the clamping stagnation phenomenon caused by the fact that impurities generated by sliding friction between the square shaft and the output shaft enter the lubricating oil can be effectively prevented, and the accuracy of tool changing action is ensured.

Drawings

The utility model is further described with reference to the following figures and embodiments.

Fig. 1 is a schematic structural view of the present invention.

Fig. 2 is a schematic top view of the structure of fig. 1.

In the figure: 1. the oil drain structure comprises a shaft body, 2 parts of a mounting seat, 2 parts to 1 parts of a column body, 2 parts to 2 parts of a mounting flange, 3 parts of a groove, 4 parts of an oil drain hole and 5 parts of an oil drain hole.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

The square shaft for the ATC tool magazine shown in the figures 1 and 2 comprises a shaft body 1 with a square cross section and a mounting seat 2, wherein the mounting seat 2 comprises a circular cylinder 2-1 and a mounting flange 2-2, the cylinder 2-1 and the shaft body 1 are of an integral structure, the mounting flange 2-2 is fixedly connected with the cylinder 2-1, and mounting holes are uniformly distributed in the circumferential direction of the mounting flange 2-2.

The outer circumferential surface of the shaft body 1 is provided with a groove 3 for storing lubricating oil, and the groove 3 extends around the outer circumferential surface of the shaft body 1 along the axial direction;

an oil drainage hole 4 is formed in the center of the shaft body 1, and the oil drainage hole 4 penetrates through the shaft body 1 and the column body 2-1.

Two centrosymmetric oil discharge holes 5 are radially formed in the column body 2-1 below the mounting flange 2-2, and the oil discharge holes 5 are communicated with the oil discharge hole 4.

Install perpendicularly in tool changer's box when the square shaft of structure so uses, with the square hole sliding fit of output shaft, wherein 4 lower extremes in the draining hole block up, the lubricating oil of joining in the slot 3 plays better lubricated effect, at the flexible in-process of output shaft, lubricating oil can flow into draining hole 4 from 1 up end of axis body, and along draining hole 4 vertical drop from oil drain hole 5 discharge, through filtering back circulation flow get back to in the slot 3 once more, thereby under the prerequisite of guaranteeing the slip effect between square shaft and the output shaft, can prevent effectively because the impurity that sliding friction produced between square shaft and the output shaft from getting into lubricating oil, cause the jamming phenomenon that the output shaft slides and appear, the accuracy of tool changing action has been guaranteed.
