A marking hole drilling jig for plunger

Abstract

The invention relates to a fixture for drilling mark holes in plunger parts. The fixture comprises a bottom plate. One end of a double-thread screw is screwed to the bottom plate; the other end of the double-thread screw penetrates a press plate and is screwed to a locknut. An ejector post is disposed on the bottom plate on one side of the double-thread screw; one end of the ejector post extends out of the bottom plate and is abutted to the press plate. A drill bushing positioning plate is disposed on one side of the bottom plate; drill bushings which are spaced are disposed in the drill bushing positioning plate through bushings; each drill bushing is provided with a drilling hole inside; a positioning block and a positioning seat are also fixedly connected onto the bottom plate. The fixture is simple in structure and convenient to mount; a plunger part is clamped and locked and is accurately positioned through a positioning plate, the positioning block and a positioning rod, multiple mark holes are machined once by extending a drill bit into the symmetric drill bushings on the drill bushing positioning plate, machining efficiency is greatly improved, production cost is saved for enterprises, secondary clamping is avoided, and labor intensity is reduced for workers.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a marking hole drilling fixture for a plunger. Background technique [0002] In order to distinguish the various models of the plunger parts, in the prior art, the marking holes are usually drilled on the plunger parts. Since the marking holes are arranged at intervals, in the prior art, after drilling a marking hole, the post is usually drilled. The plug moves a certain distance again to carry out the drilling of the next marking hole. This drilling method not only increases the labor intensity, but also greatly wastes time, takes time and effort, and affects the processing efficiency. Contents of the invention [0003] In view of the above-mentioned existing problems, the applicant has made researches and improvements, and provides a marking hole drilling jig for plunger parts, which effectively realizes the drilling of the marking holes in place at one time, and greatly improves the proc...

[0002] In order to distinguish the various models of the plunger parts, in the prior art, the marking holes are usually drilled on the plunger parts. Since the marking holes are arranged at intervals, in the prior art, after drilling a marking hole, the post is usually drilled. The plug moves again for a certain distance to drill the next marked hole. This drilling method not only increases the labor intensity, but also greatly wastes time, is time-consuming and laborious, and affects the processing efficiency.
