Problems solved by technology

[0003] ①When the upper tool holder moves back and forth, there is a sudden sudden impact, which affects the movement accuracy and poor stability
[0004] ② When the special-shaped cam moves, there will be a back-and-forth movement gap, which is only suitable for slow movement
[0005] ③ Special-shaped cams are easy to wear and have a short service life
[0006] ④The left and right yaw displacement distance of the upper tool holder cannot be adjusted, and the special-shaped cam must be replaced when the displacement distance needs to be changed

Abstract

The invention relates to an upper knife rest yawing shifter for a net punching machine. The shifter comprises an installation frame, a sliding connection support, a bearing base sliding block, an eccentric shaft bearing, an eccentric shaft and an upper knife rest. The upper knife rest is transversely and vertically arranged at one end of the installation frame. The sliding connection support is fixed to one end of the upper knife rest and movably assembled in the installation frame. The bearing base sliding block is assembled in the sliding connection support in the manner of being capable ofsliding up and down. The eccentric shaft bearing is assembled in an assembling hole of the bearing base sliding block. The eccentric shaft penetrates through a shaft hole of the eccentric shaft bearing, the eccentric shaft is provided with an eccentric wheel assembled in the shaft hole, and the two ends of the eccentric shaft are connected with the two sides of the installation frame in a rotatingmanner. The shifter has the advantages that when the upper knife rest moves back and forth, instant abrupt change impact is avoided, stability is good, precision is high, and service life is long; inthe moving process, generation of back and forth motion gaps is avoided, and the shifter is applicable to medium and high speed motion occasions; and for yawing displacement distance of the upper knife rest, by controlling the angle of stopping of the eccentric shaft, then the eccentricity of stopping of the eccentric wheel is controlled, and stepless adjusting is achieved.

Description

technical field [0001] The invention relates to screen flushing machine equipment, in particular to a tool rest yaw shifter on the screen flushing machine. Background technique [0002] At present, the yaw displacement method of the upper knife rest of the traditional screen punching machine is to use a special-shaped cam drive on one end of the upper knife rest to push the upper knife rest to slide, and use a compression spring on the other end to make the upper knife rest along the circumference of the special-shaped cam. Slide and reset to realize the intermittent movement of the yaw displacement of the upper tool post. This method has the following disadvantages: [0003] ①When the upper tool holder moves back and forth, there is a sudden sudden impact, which affects the movement accuracy and poor stability. [0004] ② When the special-shaped cam moves, there will be a back-and-forth movement gap, which is only suitable for slow movement. [0005] ③The special-shaped c...
