Embodiment Construction

[0038] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0039] The inner cone of the valve and the outer cone of the sealing ring are processed on the lathe equipment using special inclined die tooling. The inner and outer cones are measured using the inner and outer measuring claws of the tooling respectively. The operation process of using the tooling to measure the inner and outer cones will be described below in conjunction with the accompanying drawings.

[0040] A measuring tool for the length of an inclined cone, such as Figure 1-15 As shown, it includes main ruler 1, fixed claw 2, movable claw 3, lower auxiliary ruler 4, upper auxiliary ruler 5 and stopper 6,

[0041] The front of the main ruler 1 is provided with upper and lower rows of scale values, and the left end of the main ruler 1 is clamped with a fixed claw 2, and the fixed claw is fixed on the main ruler by a slotted countersunk scre...

Abstract

The invention belongs to the technical field of measurement, and relates to an inclined conical surface length measuring tool which comprises a main ruler, a movable claw, a fixed claw, a lower auxiliary ruler, an upper auxiliary ruler and a check block, the movable claw and the check block are fixedly connected with the main ruler, the main ruler is provided with an upper row of scale values and a lower row of scale values, and the fixed claw is provided with an outer measuring claw and an inner measuring claw. The movable claw is provided with an outer measuring claw and an inner measuring claw, the lower auxiliary ruler and the upper auxiliary ruler are fixedly connected with the movable claw, and the upper auxiliary ruler and the lower auxiliary ruler are provided with scale values at equal intervals. The movable claw is sleeved with an embossing knob of the fastening mechanism. The length of the inclined conical surface can be measured accurately and quickly, and the product quality, the production efficiency and the later-period assembling percent of pass are improved.

Description

technical field [0001] The invention belongs to the technical field of measurement, in particular to a measuring tool for the length of an inclined cone surface. Background technique [0002] In recent years, the types of butterfly valves have been diversified. Among them, the butterfly valve with triple eccentric structure uses the inner cone of the valve body and the outer cone of the sealing ring, and the combination of the two rotates to realize the function of cutting off the fluid. The inclined cone surface is mainly completed by two processes of turning and grinding, and each process needs to use measuring means to check whether the product is qualified. The conventional measurement method uses a common vernier caliper on the market to measure the length of the inclined cone surface. Because the inner cone of the valve body and the sealed outer cone are in the shape of an "eight" oblique cone, the inner and outer diameter measuring claws of the ordinary vernier calipe...
