An outer diameter caliper for the upper casing of a liquid accumulator

Abstract

The invention relates to an outer diameter caliper gauge for an upper shell of a liquid accumulator and belongs to the technical field of outer diameter caliper gauges. The outer diameter caliper gauge comprises a caliper gauge body, the caliper gauge body is provided with a dimension scale zone and a tolerance scale zone, the two sides of the bottom of the inner wall of the caliper gauge body are each provided with an anti-abrasion pad, a limiting rod is arranged above the anti-abrasion pads, a limiting block is arranged at the bottom of the limiting rod, a tooling scale containing box is arranged at one side of the bottom of the caliper gauge body, a telescopic tooling scale is arranged in an inner cavity of the tooling scale containing box, an opening is formed in one side of the tooling scale containing box, when the outer diameter of the air conditioner liquid accumulator is detected, protection can be provided in the measurement process through the limiting block, the situation that the whole caliper gauge is embedded into the shell to be collided due to excessive force is avoided, through the telescopic tooling scale, when disqualification is detected in the measurement process, the diameter of the shell can be roughly estimated, information can be fed back in time, through additional arrangement of a thickness detection block, the diameter of the shell can be measured, whether the thickness of the shell is qualified or not can be detected, functions are diversified, and practicability is great.

Description

technical field [0001] The invention relates to an outer-diameter caliper for an upper casing of a liquid storage device, and belongs to the technical field of outer-diameter caliper. Background technique [0002] In the batch manufacturing process of the factory, only by processing high-precision mechanical parts can it be possible to manufacture high-quality equipment. High-precision part size is the basic requirement of high-precision parts. When testing the outer diameter of the air-conditioning reservoir, the high-precision outer circle size is generally ground out, and the size of the part has a tolerance zone. After the processing is completed, check whether the processing size is qualified with a caliper. When measuring the outer diameter of the air-conditioning reservoir, there is a through end and a stop end. When inspecting the workpiece, as long as the through end can pass and the stop end cannot pass, it is a qualified product. The disadvantages of this calipe...

Problems solved by technology

[0003] The technical problem to be solved by the present invention overcomes the existing defects, and provides an outer diameter caliper for the upper housing of the liquid reservoir, which can protect the entire caliper from being embedded in the housing due to excessive force during measurement and cause collisions through the limit block. , when a failure is detected during measurement by a telescopic tool ruler, the diameter of the shell can be roughly estimated, and information can be fed back in time. Through the addition of a thickness detection block, not only the diameter of the shell can be measured, but also the shell Whether the thickness of the body is qualified can effectively solve the problems in the background technology
