Abstract
The utility model relates to a low-production-cost brake valve coaxiality measuring scale capable of fast and accurately measuring the value of the coaxiality of a brake valve rod. The brake valve coaxiality measuring scale comprises a vernier height scale. A vernier is sleeved on the main scale rod of the vernier height scale. A scale clamp connected with the vernier vertically clamps a dial indicator. A measuring block is sleeved on the main scale rod of the vernier height scale and is arranged under the vernier. The measuring block is fixed on the main scale rod through a locking screw. A rectangular through hole is disposed on the measuring block and passes through the top end and the bottom end of the measuring block. The side surface of the measuring block is equipped with an outwardly-protruding cylinder. The brake valve coaxiality measuring scale has advantages that the brake valve coaxiality measuring scale is formed by reconstructing the vernier height scale so as to achieve low cost and easy use, that the brake valve coaxiality measuring scale may simultaneous measure the excircle and the inner hole of the brake valve rod and achieves fastness and high efficiency, and that the dial indicator is used so as to guarantee measuring precision.

Background technology
CN201593969U, title " a kind of the coaxiality of valve rod of derailment automatic brake valve for railway truck measurer ", it comprises a U shape seat, contour V shape groove is respectively offered on the biside plate top of described U shape seat, and described V shape bottom land mouth is greater than the maximum physical dimension of tested valve rod ring flange apart from the distance of U shape seat bottom land; A survey post is respectively installed at biside plate middle part, and two survey posts are parallel and contour, and the height of surveying post centre distance U shape seat bottom is greater than the maximum physical dimension of tested valve rod ring flange; Described survey post measuring junction is provided with the not-go-end shaft shoulder and the go side shaft shoulder, and the length of measuring junction is less than the degree of depth of tested valve rod hole, and the diameter of the not-go-end shaft shoulder is definite by tested valve rod Kongzui major diameter, and the diameter of the go side shaft shoulder is determined by tested valve rod Kongzui minor diameter.Described U shape seat width of rebate is greater than the thickness of two tested valve rod ring flanges.The described go side shaft shoulder is two, and one in the end of surveying post, and another is in the position near the not-go-end shaft shoulder.It is parallel that post is surveyed in the baseplane of described U shape seat and described two, in the bottom surface of described U shape seat, offers symmetry groove.It is parallel that post is surveyed in the baseplane of described U shape seat and described two, in the bottom surface of described U shape seat, offers symmetry groove.Shortcoming: this coaxiality of valve rod of derailment automatic brake valve for railway truck measurer, cost of manufacture is high, uses loaded down with trivial detailsly, and measuring accuracy is low.
Utility model content
Purpose of design: for avoiding the deficiency in background technology, design a kind of not only production cost low but also can fast, accurately measure the brake valve coaxality measurement chi of braking valve rod right alignment numerical value.
Design proposal: for realizing above-mentioned purpose of design.1, in vernier height gauge, vernier is enclosed within on primary division rod, the table folder being connected with vernier vertically clamps dial gauge, measure on the primary division rod that piece is enclosed within vernier height gauge and be positioned at vernier below, measuring piece adopts lock-screw and primary division rod to fix, this measurement piece is provided with and connects the rectangular through-hole at upper and lower two ends and measure the design that piece side is outer convex cylindrical, is technical characteristics of the present utility model.The object of design is like this: while using due to braking valve rod, the right alignment of external diameter and endoporus is all required to reach use acceptance value, this just need to detect measurement to braking valve rod, braking valve rod is inserted in to the cylinder of measuring piece, and by moving cursor height gauge, dial gauge gauge head is touched be positioned at the braking valve rod outer circle diameter of below, with the light compacting of finger ovable valve stem, promoting braking valve rod rotates around cylinder, because the diameter of cylinder is the theoretical standard value in hole in braking valve rod, if its end face of flange overlaps and is close to measurement piece side after braking valve rod inserts in cylinder, and the braking valve rod dial gauge registration in rotary course inserting in cylinder does not have variation or variation range within the scope of permissible error, both the coaxiality error of having braked valve rod external diameter and endoporus is permissible error, external diameter and the endoporus of this braking valve rod are qualified.Rapidly and efficiently, owing to having utilized dial gauge, measuring accuracy is also high for whole measuring process.
Technical scheme: a kind of brake valve coaxality measurement chi, comprise vernier height gauge, in described vernier height gauge, vernier is enclosed within on primary division rod, the table folder being connected with vernier vertically clamps dial gauge, measure on the primary division rod that piece is enclosed within vernier height gauge and be positioned at vernier below, measure piece and adopt lock-screw and primary division rod to fix, this measurement piece is provided with and connects the rectangular through-hole at upper and lower two ends and measure piece side is outer convex cylindrical.
The utility model is compared with background technology, and the one, brake valve coaxality measurement chi is formed by vernier height gauge transformation, and cost is low, easy to use; The 2nd, brake valve coaxality measurement chi can be measured braking valve rod cylindrical and inner hole simultaneously, measures rapidly and efficiently; The 3rd, use dial gauge registration, guaranteed measuring accuracy.
