Elastic clamp applied to thin sheet parts of laser micromachining machine tool

Abstract

The invention discloses an elastic clamp applied to thin sheet parts of a laser micromachining machine tool. The clamp comprises a clamp body (15), a fixed clamp base (3), a movable clamp base (12) and a screw rod (14), wherein a nut (7) is connected to the middle of the screw rod (14); the screw rod (14) penetrates through a through groove of the clamp body (15); the left end of the screw rod (14) is inserted into a left end hole of the clamp body (15); the right end of the screw rod (14) is inserted into a right end hole of the clamp body (15); a rotary knob (17) is fixed to the right end of the screw rod (14); the nut (7) is clamped in the through groove in the middle of the clamp body (15); the fixed clamp base (3) is fixed to the clamp body (15); a dovetail groove under the movable clamp base (12) is connected to a dovetail at the upper part of the clamp body (15); the movable clamp base (12) is connected to the nut (7) through a spring I (9). The elastic clamp is simple in structure, convenient to adjust, low in cost and wide in adjusting range, and has good generality.

Description

technical field [0001] The invention relates to a clamp, in particular to an elastic clamp for sheet parts of a laser micromachining machine tool. Background technique [0002] Laser micromachining machine tools use the laser beam to focus the spot to etch the parts, directly scan and write micrographics on the base material, or process three-dimensional microstructures, or perform microhole processing. Laser micromachining machine tools are currently mainly used in the surface microstructure processing of thin slice parts, such as silicon wafers, ceramic wafers, etc. These materials are mostly brittle materials with thin thickness, and a slightly larger clamping force will break the material, so for brittle The positioning and clamping of large thin sheet parts on the laser micromachining machine becomes a problem. [0003] At present, the positioning and clamping of thin sheet parts of laser micromachining machine tools is usually carried out with adhesive tape. The nega...

Problems solved by technology

[0003] At present, the positioning and clamping of thin sheet parts of laser micromachining machine tools is usually carried out with adhesive tape. The negative pressure generated by the flow forms an adsorption force on the parts, but the corresponding processing parts of the parts on the fixture need to be processed to accommodate waste materials. Therefore, with the different sizes of parts and different processing positions, the fixtures must be changed accordingly. This kind of fixture is universal. Relatively poor
