Abstract

The invention discloses a cylinder part inner hole depth detection measuring tool and relates to a depth detection measuring tool. The depth of a blank of a cylinder part produced which is by adopting a thermal composite extrusion method in the prior art and provided with a parabola-shaped head part is large, and a general depth vernier caliper for measuring the depth of the parabola-shaped cylinder part does not exist in the prior art. The invention just aims to solve the above problem. The cylinder part inner hole depth detection measuring tool comprises a measuring head, a measuring rod, a depth vernier scale, a vernier and at least one fixed jackscrew; the measuring head is a rod body with one end provided with a tip part, the other end of the measuring head is fixedly connected with one end of the measuring rod, the vernier is a circular cylinder, the vernier sleeves the measuring rod in a sliding mode, one end of the depth vernier scale is fixedly connected with one end of the vernier, and the fixed jackscrew is installed on the outer side wall of the vernier in a threaded connection mode. The invention belongs to the field of machining detection.

Description

technical field [0001] The invention relates to a measuring tool for depth detection, in particular to a measuring tool for detecting the depth of an inner hole of a cylinder, belonging to the field of mechanical processing detection. Background technique [0002] The heads produced by the prior art all have a parabolic cylindrical part. The original processing method is to directly process the round steel. The cutting amount of the inner hole and the shape of the workpiece is very large, the material utilization rate is only 20%, and the material waste is very large. Seriously, the production efficiency is extremely low. In view of the above situation, the processing technology of this piece is innovated, and the blank of this piece is made by thermal compound extrusion method, which can save 48% of materials and double the production efficiency. The blank is made by hot composite extrusion. In order to ensure the size of the extrusion is qualified and avoid waste products,...
