Abstract
The utility model discloses an open-file dimension testing fixture for components with conical parts, wherein components with conical parts can be easily positioned and measurement positions on the components can be easily selected. The testing fixture overcomes the defect that parts of a conical structure are hard to position and measurement positions on the parts are not easy to select during detection by means of existing open-file dimension testing devices in the prior art. The open-file dimension testing fixture for components with conical parts comprises a testing fixture matrix. The testing fixture matrix is provided with a conicity gauge with a truncated cone-shaped hole. The smaller bottom of the truncated cone-shaped hole is arranged upward and the larger bottom of the truncated cone-shaped hole is arranged downward. The testing fixture matrix is provided with a detection instrument. The detecting end of the detection instrument passes through the testing fixture matrix and is arranged downwards. The open-file dimension testing fixture can be adapted to occasions where existing open-file dimension testing fixtures are suitable for. Due to the adoption of the open-file dimension testing fixture, the conical part of a component to be tested can be positioned and the open-file dimension of the component can be measured with the conicity gauge as a measuring reference. Thus, whether the open-file dimension of the component is qualified or not can be visually measured.
Description
Technical field
The utility model relates to a kind of measurement mechanism, relates in particular to a kind of grade size checking device of opening with cone object.
Background technology
Aborning, numerous parts is with conical section, when needs are surveyed on the part size of other structures and cone structure linkage section and are namely opened grade size, because conical section does not have the plane, often difficulty is located part, and when measuring also difficult choose can Measurement accuracy the position, cause detecting inconvenience.
China Patent Publication No. CN2098673U, in open day on March 11st, 1992, the name of utility model is called taper detector, and this application case discloses a kind of taper detector, and it is comprised of level meter, bracing frame, locating rack, testing stand, milscale.As long as find the strong point when adopting this device to detect, top locating surface, rotation milscale be when being horizontal level meter, on the milscale shown in reading be the back draught value of crystallizer sidewall.This utility model weak point is still and is difficult for choosing measuring position, pure by manual observation when detecting, and is difficult for the part with cone structure is positioned.
The utility model content
It is difficult to the part location and be difficult for choosing the deficiency of measuring position during with the cone structure part in inspection that the utility model has overcome the existing pick-up unit of opening grade size, provides a kind of easily to the cone object location and easily choose grade size checking device of opening of measuring position.
The utility model is achieved through the following technical solutions:
A kind of grade size checking device of opening with cone object, comprise the cubing matrix, described cubing matrix is provided with the cone gauge with the round platform hole, described round platform hole handle facing up, the bottom surface is downward greatly, described cubing matrix is provided with measuring instrument, the test side of described measuring instrument run through the cubing matrix and direction downward.Round platform hole in the cone gauge designs corresponding with the cone structure part of tested part in advance, so just cone gauge can be inserted in the conical section of tested part, realize easily the location, and in the process of being inserted in the test side of the non-cone portion branch of tested part and measuring instrument near and compress the test side, so just can read the numerical value of dial gauge, and compare with reading of standard, it is oversize, too small, still qualified to draw out shelves, in this process, utilize the cubing matrix as measuring basis and measurement and positioning, read soon to have finished accurately detection.
As preferably, described measuring instrument is dial gauge, and described test side is the gauge head of dial gauge.Dial gauge can show with pointer on dial plate according to the compressed distance of gauge head, so can be accurate and visual measure tested part and whether meet the requirements.
As preferably, described gauge head end is hemisphere face.The gauge head end is hemisphere face, therefore contacts for point with the part top, can reduce the measuring error that causes because of part top injustice.
As preferably, the tapering in the round platform hole in the described cone gauge is 7 to 24.
Therefore, the beneficial effects of the utility model are: (1) has the cone gauge with the round platform hole, can locate the tested part conical section and open a grade dimensional measurement with cone gauge as measuring basis; (2) can read by the pointer of dial gauge the move distance of gauge head, thereby whether measure out intuitively grade size qualified.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the utility model side view.
Among the figure: cubing matrix 1, cone gauge 2, dial gauge 3, gauge head 4.
Embodiment
Below by embodiment, by reference to the accompanying drawings the technical solution of the utility model is described further:
A kind of grade size checking device of opening with cone object as shown in Figure 1 and Figure 2, comprise cubing matrix 1, described cubing matrix 1 is provided with the cone gauge 2 with the round platform hole, described round platform hole handle facing up, the bottom surface is downward greatly, described cubing matrix 1 is provided with measuring instrument, the test side of described measuring instrument run through cubing matrix 1 and direction downward.Described measuring instrument is dial gauge 3, and described test side is the gauge head 4 of dial gauge 3.Dial gauge 3 can show with pointer on dial plate according to gauge head 4 compressed distances, so can be accurate and visual measure tested part and whether meet the requirements.Described gauge head 4 ends are hemisphere faces.Gauge head 4 ends are hemisphere faces, therefore contact for point with the part top, can reduce the measuring error that causes because of part top injustice.The tapering in the round platform hole in the described cone gauge 2 is 7 to 24.
When opening grade size detection, the round platform hole designs tapering 7 to 24 in advance, and the cone structure part of itself and tested part can be fitted.With the cone structure part that tested part is inserted in cone gauge 2, just can realize easily the part location.And in the process of being inserted in, the non-cone portion branch of tested part and the gauge head of measuring instrument 4 near and compress gauge head 4, so just can read the numerical value of dial gauge 3, and compare with reading of standard, it is oversize to draw out shelves, too small, or qualified, wherein reading of standard refers to the utility model and is inserted in the standard qualified part, when gauge head 4 is pressed, the reading of dial gauge 3 dial plates or can be by calculating, the shelves of opening that for example require are of a size of 3.2 centimetres, the distance that gauge head 4 stretches out cubing matrix 1 lower surface is 6.2 centimetres, and therefore the reading of dial gauge 3 is exactly reading of standard when gauge head 4 is pressed into 3 centimetres.In this process, utilize cubing matrix 1 lower surface as measuring basis, can read soon to finish accurately detection.
