Infrared scribing instrument with light diameter adjusting mechanism

Abstract

The invention discloses an infrared scribing instrument with a light diameter adjusting mechanism. The infrared scribing instrument comprises a laser device, a wire, a base and a supporting column, wherein a fixing sleeve seat is fixedly installed on the outer surface wall of the laser device, a transmission mechanism is arranged between the fixing sleeve seat and the supporting column, and the infrared scribing instrument further comprises an installing base, a driving plate and matching plates. According to the infrared scribing instrument, the driving plate matches with a wedge-shaped block through a hexagonal groove and drives the matching plates to move, a sliding rod on the outer surface wall of the matching plates synchronously slides with a clamping groove in a star-shaped plate so as to limit the matching plates, the adjacent surfaces of the plurality of groups of matching plates expand outwards while being attached to one another, the opening degree adjustment of fixing gears of the laser devicd is realized, and therefore, a laser device library is subjected to opening degree adjustment of a plurality of groups of fixing gears so as to meet the machining requirements of different workpieces, and the use effect of the infrared scribing instrument is improved.

Description

technical field [0001] The invention relates to the technical field of optical instruments, in particular to an infrared scribing instrument with a light diameter adjusting mechanism. Background technique [0002] At present, there are still deficiencies in the existing infrared scribing instrument. First, the existing infrared scribing instrument will form a line of light on the workpiece to be processed when it is working, but the width of the projected light is relatively fixed. Most of the transmitting ends of some infrared scribing instruments lack the wire diameter adjustment mechanism of the light, so that the infrared scribing instrument cannot process the demand and remember the adjustment of the wire diameter, thereby reducing the use effect of the infrared scribing instrument; secondly, the existing Although the laser in the infrared scribing instrument is mostly provided with a deflection mechanism between the pillar and the deflection mechanism, most of the defl...

[0002] At present, there are still deficiencies in the existing infrared scribing instrument. First, the existing infrared scribing instrument will form a line of light on the workpiece to be processed when it is working, but the width of the projected light is relatively fixed. Most of the transmitting ends of some infrared scribing instruments lack the wire diameter adjustment mechanism of the light, so that the infrared scribing instrument cannot process the demand and remember the adjustment of the wire diameter, thereby reducing the use effect of the infrared scribing instrument; secondly, the existing Although most of the lasers in the infrared scribing instrument are provided with a deflection mechanism between the pillar and the deflection mechanism, most of them can only adjust the angle based on a plane, and the activity space of the laser is relatively limited, thus reducing the scope of application of the infrared scribing instrument.
