Description
Technical Field
The utility model relates to the technical field of part detection and evaluation, in particular to a special measuring tool for detecting the axial size of a part.
Background
When the axial size of the existing part is checked, a scale groove is generally processed on a checking pin, whether the axial size of a part is qualified or not is judged by visually observing whether a limiting surface of the part is in the range of the scale groove, and visual errors are easy to occur due to visual inspection, so that the checking result is inconsistent;
disclosure of Invention
The utility model aims to provide a special measuring tool for detecting the axial dimension of a part, and aims to solve the technical problems that the axial dimension of the part is large in error through visual detection and the detection results are inconsistent in the prior art.
In order to achieve the purpose, the special measuring tool for detecting the axial size of the component comprises an inspection pin and a base, wherein the inspection pin is provided with a standard limiting block, a step cylinder and a handle, the step cylinder is arranged at one end of the standard limiting block and close to a detected part entity of the component and used for axially positioning and limiting the inspection pin, the handle is arranged at the other end of the standard limiting block and used for driving the inspection pin to rotate and axially move, the base is fixedly arranged on the bottom plane of the measuring tool, the base is provided with a standard limiting groove along the axial direction of the inspection pin and used for being matched with the standard limiting block during detection, and after the whole component is positioned by the reference of a component positioning center during detection, the inspection pin is axially inserted from one end far from the component to the limiting end face of the inspection pin and is attached to the detected end face of the component
Further, the standard limiting block adopts a cuboid, the standard limiting groove is a cross-shaped groove, and when the inspection pin is inserted into the base along the axial direction, the short edge of the cuboid of the standard limiting block is parallel to the standard limiting groove.
Further, a bushing is arranged in the base and used for guiding and centering the inspection pin.
Furthermore, the standard limiting block, the step cylinder and the handle are integrally formed.
Furthermore, the standard limiting block and the step cylinder are integrally formed, and the handle is in threaded fastening connection with the limiting block.
The utility model has the beneficial effects that:
1. by changing the inspection pin style (inspection pin with scale groove → inspection pin with limit block) and adding a base matched with the inspection pin, whether the axial dimension of the part is qualified or not can be judged by observing whether the standard limit block of the inspection pin can smoothly pass through the standard limit groove on the base or not by rotating the inspection pin during inspection.
2. The measuring tool is accurate and visual in detection, and the consistency of detection results is good.

Detailed Description
The following describes embodiments of the present invention in detail.
Referring to fig. 1-3, L ═ ± is an axial control dimension of a component to be detected in the present invention, the measuring tool for detecting an axial dimension of a component of the present invention comprises an inspection pin 1 and a base 2, the inspection pin 1 is provided with a standard stopper 11, a stepped column 12 and a handle 13, the stepped column 12 is disposed at one end of the standard stopper 11 and close to a measured part of the component 3, the inspection pin 1 is axially positioned and limited by the stepped column 12 during component detection, the handle 13 is disposed at the other end of the standard stopper 11, an operator drives the inspection pin 1 to rotate and axially move through the handle 13, the base 2 is fixedly mounted on a bottom plane of the measuring tool, the base 2 is provided with a standard stopper groove 21 along an axial direction of the inspection pin for matching with the standard stopper 11 during detection, in the present embodiment, the standard stopper 11 is a rectangular parallelepiped, standard spacing groove 21 sets up to cross type groove, during the detection, whole portion article with a portion article location center benchmark location back, when inspection round pin 1 inserted base 2 along the axial from the one end of keeping away from a portion article 3, the minor face that will guarantee 11 cuboids of standard stopper was roughly parallel with standard spacing groove 2, could insert until inspection round pin spacing terminal surface 14 and a portion article detected the terminal surface 31 laminating.
In this embodiment, a bushing 4 is further provided in the base 2 for guiding and centering the inspection pin 1.
The standard stopper 11, the step column 12 and the handle 13 in this embodiment can be integrally formed, and also the standard stopper 11 and the step column 12 can be integrally formed, and the handle 13 and the stopper 11 are fastened and connected into a whole through a bolt.
The detection process of the utility model comprises the following steps:
the position of an article is well determined by an article positioning center reference, the article is ensured not to shake, the inspection pin is rotated, the short edge of a standard limiting block of the inspection pin can be inserted when being approximately parallel to a standard limiting groove, the inspection pin is rotated again until the limiting end face of the inspection pin is attached to the measured end face of the article, whether the standard limiting block can smoothly pass through the limiting groove is judged by visual and hand feeling, if the standard limiting block cannot pass through the limiting groove, the axial dimension of the article is unqualified, otherwise, the inspection pin is qualified.
While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model.
