Tool constant velocity device

Abstract

The invention discloses a cutter constant-speed device and belongs to the technical field of grating ruling machinery. The cutter constant-speed device aims at solving the problem that processing accuracy is difficult to ensure in the existing grating ruling process and lots of transmission errors can be caused due to a complex transmission mechanism and can achieve grating ruling with different widths. The cutter constant-speed device comprises two cutter constant-speed mechanisms which are separately arranged on two opposite surfaces of a substrate, the cutter constant-speed mechanisms can move in a reciprocating mode under the driving of constant-speed cams, one end of a swinging rod is connected with a first push rod, the other end of the swinging rod is connected with a second push rod, the swinging rod can swing in a reciprocating mode under the driving of the first push rod, the relative position of an adjusting knob on the swinging rod can be changed, and the moving distance specific value of the first push rod and the second push rod can be changed by changing the position of the adjusting knob on the swinging rod. The cutter constant-speed device ensures constant-speed motion of a scribing cutter bridge, can conveniently adjust moving distance of a scribing cutter by adjusting the position of the knob on the swinging rod and does not need to change the structure of the cutter constant-speed mechanisms and replace elements.

Description

technical field [0001] The invention belongs to the field of grating marking machines, in particular to a tool constant velocity device capable of adjusting the marking width of the grating in the grating marking machine. Background technique [0002] The grating is engraved by mechanical methods. At present, two methods are mainly used: intermittent engraving and continuous engraving; when engraving large gratings, continuous engraving is generally used, that is, the indexing system drives the grating blank to move continuously, and the engraving system drives the cutting tool. Carry out scoring, and at this time, the tool movement speed is required to be constant during the scoring process. [0003] "Instrument Technology and Sensors" 1984, "A Brief Introduction to Large-scale Grating Scribing Machines in the United States" pointed out that the existing constant-velocity marking system mainly uses the curve correction plate to correct the speed of the crank double pendulum...
