Abstract
The utility model discloses an inner diameter checking fixture comprising a base. A substrate is arranged on the base. A clamping plate is arranged on the substrate. A dial gauge and a gauge head are arranged on the two sides of the clamping plate. A measuring mechanism is arranged on the clamping plate. The measuring mechanism is equipped with a connecting member which is in contact with the gauge head. The upper part of the measuring mechanism is provided with an arc measuring head. A spring is arranged inside the measuring mechanism. The measuring mechanism is composed of two components which are connected by the spring. The inner diameter checking fixture has the advantages of simple structure, low cost, simple operation and high operation efficiency.
Description
Technical field
The utility model relates to a kind of inner diameter check tool, is specially adapted to the production verification of ring-type product.
Background technology
At present, in the production of the annular element of a lot of plant equipment, in order to ensure that product can use, internal diameter that must measure annular part, but in actual production, product internal diameter is relatively difficult for detecting, bad detection and detection forbidden.In the market, the instrument of measuring internal diameter is mainly three-coordinates measuring machine, but its input cost is larger, hundreds of thousands unit at least, even up to ten million units of millions of units at most, accuracy in detection is high, but testing process is cumbersome, loaded down with trivial details, must there is corresponding professional and technical personnel's operation.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, provides a kind of detection efficiency high, and cost is low, simple in structure, the inner diameter check tool that accuracy is high.
The purpose of this utility model is achieved through the following technical solutions: a kind of inner diameter check tool, comprise base, base is provided with pedestal, pedestal is provided with clamping plate, and clamping plate both sides are provided with clock gauge and gauge outfit, and clamping plate are provided with measuring mechanism, web member is housed on measuring mechanism, web member contacts with gauge outfit, and measuring mechanism top is provided with measuring head, and measuring mechanism inside is provided with spring.
Further improvement of the utility model is: measuring head is arc.
Further improvement of the utility model is: measuring mechanism is made up of two measuring pieces, and two measuring pieces connect by spring.
Further improvement of the utility model is: web member is connected with one of them measuring piece in measuring mechanism, and does not contact with another simultaneously.
The utility model compared with prior art has the following advantages:
Device described in the utility model, simple in structure, cost is low; Measuring head protrudes and is arranged on measuring mechanism, can make product just be stuck on measuring head when measurement, when product is measured, can be fixed on well on measuring mechanism, has ensured the accuracy of the product size detecting; When measurement, only annular products internal diameter need be enclosed within on measuring head, thereby control the reading of clock gauge by spring-compressed, easy to operate, detection speed is fast, causes product detection efficiency high, be applicable to factory and workshop and use, and because measuring head has radian, can be applicable to more products.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1-base, 2-pedestal, 3-clamping plate, 4-clock gauge, 5-gauge outfit, 6-measuring mechanism, 7-web member, 8-measuring head, 9-spring, 10-measuring piece.
embodiment:
in order to deepen understanding of the present utility model, below in conjunction with example and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows a kind of embodiment of the utility model inner diameter check tool, described inner diameter check tool comprises base 1, described base 1 is provided with pedestal 2, pedestal 2 is provided with clamping plate 3, clamping plate 3 both sides are provided with clock gauge 4 and gauge outfit 5, clamping plate 3 are provided with measuring mechanism 6, web member 7 is housed on measuring mechanism 6, web member 7 contacts with gauge outfit 5, measuring mechanism 6 tops are provided with arc measuring head 8, measuring mechanism 6 inside are provided with spring 9, measuring mechanism 6 is made up of two measuring pieces 10, two measuring pieces 10 connect by spring 9, web member 7 is connected with one of them measuring piece 10 in measuring mechanism 6, and do not contact with another simultaneously.This inner diameter check tool is simple in structure, and cost is low, simple to operate, and operating efficiency is high.
The principle of work of the utility model inner diameter check tool is: when the internal diameter of measurement products, first be enclosed within on arc measuring head 8 clock gauge zero clearing with sample blocks, then ring-type product is enclosed within on the arc measuring head 8 on measuring mechanism 6 tops, two measuring pieces 10 of testing agency 6 can be adjusted position by the telescopic action of spring 9, make the web member 7 being connected with one of them measuring piece 10 change position, thereby the position of adjusting gauge outfit 5 changes the reading of clock gauge 4, fix after product, can be from clock gauge 4 reading, be the internal diameter of product.
The foregoing is only explanation embodiment of the present utility model; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
