Problems solved by technology

However, since the original measurement function of this contact three-coordinate measuring head is used when the measuring head (seat) is fixed, if the measuring head is used to realize the coordinate positioning function of the machine tool spindle, the measuring head must be clamped on the machine tool.

Embodiment Construction

[0013] The contact type coordinate locator with annular luminous display of the present invention is composed of a contact 1, a casing and a reset mechanism inside the casing. Wherein the casing is divided into an upper casing 7 and a lower casing 2 . The reset mechanism is a magnetic elastic reset mechanism with a reset accuracy of 0.0005 mm. A luminescent display unit is connected above the magnetic elastic reset mechanism 3 in the casing. The luminous display unit is connected with a luminous body through a trigger electrical signal switch connected with the contact, and the luminous body is a light emitting diode 4 . The illuminant is set in the ring-shaped light-transmitting body 5, which has a cylindrical shape and has an annular shoulder in the middle. The annular shoulder is partially installed between the upper shell and the lower shell, so that The realization of 360 ° circular display.

Abstract

The invention discloses a contact type coordinate locator with annular luminous display. The locator comprises a contact, a shell and a reset mechanism in the shell, and is characterized in that: the shell is divided into an upper shell and a lower shell; a luminous display unit is arranged between the upper shell and the lower shell; a luminous body of the luminous display unit triggers to turn on/off an electric signal switch through the displacement of the contact; and an annular light transmitting body is annularly exposed at 360 degrees between the upper shell and the lower shell. According to the invention, the coordinate positions of the center of the lathe spindle relative to a workpiece hole, side and workpiece center can be quickly and accurately determined, and the data such as aperture, width, height, depth, angle, curved surface and the like of the parts can be measured. The contact type coordinate locator with annular luminous display can ensure that the trigger signal is observed by eyes of people, the repeated location precision of the locator can reach 0.001 mm which is 10 times that of an optical coordinate locator, and the location speed is 3 times higher than that of the optical coordinate locator.

Description

【Technical field】 [0001] The invention relates to the field of on-line precision measurement and processing of numerical control machine tools, in particular to a high-precision contact coordinate locator with a ring-shaped luminous display. 【Background technique】 [0002] When machining a CNC machine tool, when a certain hole center needs to be used as the machining reference, the center of the machine tool spindle and the center of the hole need to be coincident at the same coordinate position. For such positioning measurement, especially the positioning measurement of small holes, the operating technology It is very difficult. [0003] Usually, people use an optical coordinate locator to center and patrol the workpiece, but the speed is slow and the accuracy is only 0.01mm. [0004] In addition, a lever dial gauge is used for positioning. Although the lever dial indicator can be used to determine the position of the hole, it is necessary to manually swing the spindle of...
