Embodiment 1

[0021] Measure the inner diameter of the plunger sleeve (integral type) ( figure 1 ) For example:

[0022] The plunger sleeve inner diameter measuring head (split type) of this embodiment ( image 3 ) is the original plunger sleeve inner diameter measuring head (integral) ( figure 1 ) The measuring part 5 and the positioning clamping part 4 are separately designed into two parts: the measuring head 7 and the positioning sleeve 6.

[0023] Measuring head 7 is the measuring part of the inner diameter measuring head of the plunger sleeve. Due to its special working environment and performance requirements, the selected material requires small heat treatment deformation, good wear resistance, and good dimensional stability after heat treatment and aging, so GCr15 is still selected. Manufactured from bearing steel. GCr15 bearing steel will obtain a stable metallographic structure after repeated internal stress elimination, multiple tempering and ice-cooling treatments during p...

Abstract

The invention relates to an inner-diameter measuring head of a plunger sleeve, belonging to the technical field of pneumatic measuring. The split-type inner-diameter measuring head of the plunger sleeve is characterized in that the inner-diameter measuring head comprises a measuring head used as a measuring part and a positioning sleeve arranged at the periphery of the measuring head; the positioning sleeve is used for positioning and clamping, the measuring head and the positioning sleeve are two independent parts, the measuring head and an air inlet joint are connected into a whole, and the air inlet joint is connected with a float-type pneumatic gauge. As common materials are selected as far as possible on the basis that the functional requirements are met, the split-type inner diameter measuring head of the plunger sleeve is economical and needs no cutting or little cutting. With simple structure, light weight, easy manufacturing, convenient using, good safety, high reliability, good manufacturability, beautiful appearance, high production efficiency and low manufacturing cost, the split-type inner diameter measuring head manufactures parts meeting the using requirements with the least workload and the lowest processing cost,. Moreover, the material cost of the inner-diameter measuring head is greatly reduced.

Description

1. Technical field [0001] The invention relates to a plunger sleeve inner diameter measuring head, in particular to a split type plunger sleeve inner diameter measuring head, which belongs to the technical field of pneumatic measurement. 2. Background technology [0002] At present, an integral plunger sleeve inner diameter measuring head such as figure 1 , including the measuring head 2 and the air inlet connector 1, the air inlet connector 1 is glued and pressed into the measuring head 2 to become an integral part. The structure adopted by the measuring head 2 is that the measuring part 5 and the positioning and clamping part 4 are an integral steel part, made of GCr15 bearing steel, with a maximum diameter of φ20mm and a length of 75mm. The air inlet joint 1 is connected with the buoy-type pneumatic measuring instrument 3, and is made of H62 brass, with a maximum diameter of φ8mm and a length of 23mm. The inner diameter measuring head (integral type) of the plunger slee...
