Description

Bolt overall dimension examines utensil

Technical Field

The utility model relates to an examine utensil, especially an utensil is examined to bolt overall dimension.

Background

The bolt is a common fastener, generally speaking need carry out the selective examination before the bolt dispatches from the factory, can adopt examines utensil such as slide caliper to carry out manual measurement to its external dimensions traditionally, and this kind of mode is not only consuming time hard, work efficiency is low, and manual measurement still can have the problem of the error that can't avoid moreover. In order to solve the above problems, a full-automatic image measuring instrument is available on the market, which can automatically measure the sizes of all parts of a workpiece, but the bolt is special in shape and difficult to fix according to certain requirements, and even if the bolt is fixed, the full-automatic image measuring instrument is difficult to accurately measure the width of a bolt with a threaded part, so that the measuring effect is affected. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed, can be fast, conveniently fixing bolt, and the full-automatic image measuring apparatu of being convenient for carries out measuring examining utensil to its appearance size.

The technical solution of the utility model is that: the utility model provides an utensil is examined to bolt overall dimension which characterized in that: the checking fixture comprises a base, the base is composed of a horizontal plate 1 and a vertical plate 2 which are perpendicular to each other and connected with each other, a clamp 3 is arranged on the vertical plate 2, a first slide way 4 and a second slide way 5 which are parallel to each other are arranged on the horizontal plate 1, the first slide way 4 is positioned on the central line of the horizontal plate 1, a first slide block 6 is connected with the first slide way 4 in a sliding manner, a length detection plate 7 which is vertically distributed is arranged on the first slide block 6, a second slide block 8 is connected with the second slide way 5 in a sliding manner, a baffle 9 which is horizontally distributed is connected with the second slide block 8 through a connecting plate, a third slide block 10 is also connected with the second slide way 5 in a sliding manner, a screw rod 11 is rotatably supported on the third slide block 10, two threads with opposite rotation directions are arranged on the screw rod 11, two moving seats 12 are connected with the screw rod 11 in a threaded manner, and the bottoms of the two moving seats 12 are contacted with the top end surface of, and a width detection plate 13 is further provided on the movable base 12.

Compared with the prior art, the utility model, have following advantage:

the bolt overall dimension checking fixture with the structure is simple in structure, ingenious in design and reasonable in layout, can be used for quickly and conveniently fixing a bolt to be detected in a certain posture aiming at various problems in the traditional bolt dimension detection process, and utilizes a plurality of auxiliary plates to mark the outer diameter dimension of the bolt and the length dimension of a screw part, so that the full-automatic image measuring instrument can measure the dimensions of all parts of the bolt only by detecting the distance between the plates, and is convenient and very accurate. The gauge has the advantages of simple manufacturing process and low manufacturing cost, so the gauge is particularly suitable for popularization and application in the field and has very wide market prospect.

Fig. 2 is a schematic view of a tested bolt according to an embodiment of the present invention.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 and 2: a bolt overall dimension checking fixture comprises a base, wherein the base is composed of a horizontal plate 1 and a vertical plate 2 which are perpendicular to each other and connected with each other, a clamp 3 is arranged on the vertical plate 2, a first slide way 4 and a second slide way 5 which are parallel to each other are arranged on the horizontal plate 1, the first slide way 4 is positioned on the central line of the horizontal plate 1, a first slide block 6 is connected with the first slide way 4 in a sliding manner, a length detection plate 7 which is vertically distributed is arranged on the first slide block 6, a second slide block 8 is connected with the second slide way 5 in a sliding manner, a baffle plate 9 which is horizontally distributed is connected with the second slide block 8 through a connecting plate, a third slide block 10 is also connected with the second slide way 5 in a sliding manner, a screw rod 11 is supported on the third slide block 10 in a rotating manner, two threads with opposite rotating directions are arranged on the screw rod 11, and two moving seats 12 are connected with the screw rod 11 in a, the bottom portions of the two moving bases 12 are in contact with the top end surface of the horizontal plate 1, and a width detection plate 13 is further provided on the moving bases 12.

The working process of the bolt overall dimension checking fixture with the structure form is as follows: firstly fixing the screw head part of a bolt 14 to be detected on a clamp 3, keeping the whole bolt 14 to be detected in a parallel state with a horizontal plate 1, sliding a second slide block 8 left and right, enabling one side of a baffle plate 9 to be in contact with the bottom of the screw head part of the bolt 14 to be detected, positioning the bolt, sliding a first slide block 6, enabling a length detection plate 7 on the first slide block 6 to be in contact with the end part of the bolt to be detected, enabling a third slide block 10 to be in a proper position, rotating a screw rod 11, and driving two sliding seats 12 to move oppositely after the screw rod 11 rotates until two width detection plates 13 are in contact with the two sides of the bolt 14 to be detected respectively to finish preparation work;

at this time, the distance between the side of the baffle 9 in contact with the bolt 14 to be measured and the length detection plate 7 is the length of the stud part on the bolt 14 to be measured (dimension a in fig. 2), the distance between the two width detection plates 13 is the width of the stud part on the bolt 14 to be measured (dimension B in fig. 2), and the full-automatic image measuring instrument can quickly and accurately measure the dimensions, so as to obtain the measurement data.

After the measurement operation is finished, the screw rod 11 is rotated reversely, the first slide block 6 and the second slide block 8 are both restored to the initial positions, the bolt 14 to be measured is taken down from the clamp 3, and the next bolt 14 to be measured is fixed on the clamp 3 again so as to perform the next measurement operation.
