Description

Tool positioning device

The present invention relates to a tool positioning device applied to a machine tool such as MCT to determine the relative position with respect to the end of the machining tool from the surface of the workpiece.

As an example of the tool positioning used in machine tools such as MCT, the zero setting method will be described. In the past, the zero setting method uses a machining tool to finely machine the surface of the object to be processed, It was common to set the zero point to process the object.

However, this is inevitable because the processing of the object to be processed, there was a serious problem of waste of material and zero setting time.

Representative conventional zero setting tools developed for this include the Accu Center and Height Presetter.

In the case of the accu center, the lower tool can be eccentrically moved from the upper tool. The method of using the accu center is to set the lower tool to be eccentrically rotated from the upper tool while the upper tool of the accu center is bitten by the processing tool. Thereafter, the zero point of the machining tool can be set in such a manner that the lower tool is brought into contact with the surface of the workpiece to transfer the machining tool until the lower tool is rotated in the same state without eccentric rotation from the upper tool.

However, Accu Center has a problem that only the coordinates of the x and y axes can be tracked, and there is a problem that the zero point is not precise because it must grasp the degree of equal rotation with the naked eye. There should be a problem that it takes a long time to set the standard setting, such as adjusting the radius of the accu center even if the setting is finished, and changing to a tool to be used again.

In addition, the height presetter is provided with a contact table operating from the upper surface of the body recessed, and has a structure having a dial for measuring the depression value in accordance with the depression of the contact table, the method of using the height presetter is mounted on the table After placing the height presetter on the upper surface of the object to be processed, the end of the processing tool is brought into contact with the contact table to lower the contact table by a certain distance, and the zero point of the processing tool can be set in such a manner as to convert the lowered value.

However, the height presetter has a problem that only the coordinates of the z-axis can be tracked, there is a problem in that it is applied to the system of the machine tool by converting the numerical value, and the zero setting of the height presetter itself is difficult.

Therefore, the conventional zero setting tool has a problem that it is impossible to track x, y, z coordinates with a single tool, and the zero setting is not precisely performed, and it takes a long time to set the zero point. This was in common.

For reference, the following prior art documents list recent prior art documents similar to the present invention searched through the patent information net Cypris, and the technical field and background of the present invention with reference to the following prior art documents and its development You will be able to see the status.

Publication / Registration: 1017720430000, 1020150064615, 1008173200000.

The present invention was developed to solve the conventional problems mentioned in the background, and in particular, one tool positioning device determines the relative position of the tool relative to the workpiece in the x, y and z axes, or sets the zero point. It is intended to be able to be made easily, convenient, fast and precisely.

The present invention is a means for achieving the above object, the body; A zero setter which mounts the main body on the object to be machined to hold a zero measurement reference position; A slide which is elastically conveyed in the forward / reverse direction protruding from the main body to grasp the position of the machining tool of the machine tool from the object to be machined; A stopper for engaging the zero measurement reference position of the slide from the main body and for causing the slide to protrude from the main body upon release; It is made of a tool positioning device comprising a; measuring device for measuring the conveying distance of the slide from the main body,

The tool positioning device sets the numerical value of the measuring instrument to 0 while the stopper is held on the slide of the main body, and then releases the stopper from the main body so that the slide protrudes from the zero position of the main body. The zero setter is hung on the edge of one side of the object to be mounted on the surface, and the end of the machine tool is brought into close contact with the slide, and the tool is used until the numerical value of the measuring instrument reaches the desired position. A means for determining the position of the tool in the manner of conveying the slide is proposed.

Conventional devices are all about the origin of the tool tip in the direction of the angular axis of the workpiece, but according to the means of the present invention, it is possible to easily and conveniently, quickly and precisely grasp the desired position of the machining tool, compared to the conventional one The positioning device can hold both x, y and z axes, and unlike conventional accu centers or height presetters, it does not need to be converted to numerical values. In addition, in the case of CNC machine tools, the relative position of the tool to be used can be transmitted and used immediately, thereby creating a much more convenient machining environment.
