Oblique pressing ball type movable plier mechanism of flat tongs

Abstract

The invention discloses an oblique pressing ball type movable plier mechanism of flat tongs. The oblique pressing ball type movable pliers mechanism is characterized in that the lower end face of a movable plier body is connected to the upper end face of a flat tongs body in a linear sliding mode, a jaw is fixed to the front end face of the movable plier body, an inclined pressing block mounting groove is reserved in the middle of the movable plier body, a clamping plate is fixed to the rear end of the movable plier body, and a baffle is fixed to the rear end of the clamping plate; a lead screw is in threaded connection in a threaded hole I of a supporting seat of the flat tongs, and after the front end part of the lead screw penetrates through a via hole of the baffle, the head part of the lead screw abuts against the rear end face of an L-shaped inclined pressing block; the L-shaped inclined pressing block is arranged in the inclined pressing block mounting groove, the lower end face of the L-shaped inclined pressing block is connected into a T-shaped groove of the flat tongs body in a linear sliding mode, and the upper end face of an inner clamping opening of the L-shaped inclined pressing block is an inclined face; and at least more than 1/2 of the part of a steel ball is tightly assembled in a steel ball accommodating hole formed in the front end wall of the inclined pressing block mounting groove of the movable plier body, and the inclined face of the L-shaped inclined pressing block is pressed at the upper end of the rear end of the steel ball. The oblique pressing ball type movable plier mechanism of flat tongs is low in cost and easy to machine; and the flat tongs adopting the oblique pressing ball type movable plier mechanism are accurate in positioning, high in positioning precision and good in stability.

Description

technical field [0001] The invention relates to parts of a flat-nose pliers, in particular to an oblique ball-type movable tong mechanism of the flat-nose pliers. Background technique [0002] In the traditional production process, using the movable tongs without baroclinic technology, the movable tongs cannot generate oblique downward pressure, and the workpiece will float up and move during processing, which cannot be accurately positioned, and may easily cause unstable processing quality or scrap. The angle-fixed movable pliers with oblique pressure are pressed on the inclined surface of the movable pliers body by steel balls, so the processing technology is poor and the cost is high. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art, and to provide a low-cost, easy-to-process oblique ball-type dynamic vise mechanism for the vise. The vise using the vise mechanism has accurate posit...
