Description

Technical Field

[0001] The utility model relates to the technical field of production and detection equipment for sleeves, in particular to a detection tool for sleeve inspection. Background Art

[0002] The sleeve needle is divided into two parts, the inner needle and the sleeve, and each has a cup head (the function of the cup head is to play the role of positioning and pipe position, that is, there will be no deviation and movement during the production process or mechanical activities); sometimes the inner needle is made of beryllium copper; the sleeve is generally made of steel; there are two sections inside the sleeve, the front section is used for tight fitting and pipe position with small tolerances; the rear section is used for air avoidance; the sleeve is sleeved on the inner needle and can move up and down; the inner needle is fixed on the mold bottom plate, and the sleeve is installed on the ejector plate. When ejecting, the sleeve moves up with the ejector plate. At this time, the inner needle is fixed on the mold bottom plate and does not move, so the sleeve will eject the upper product wrapped in the inner needle; among them, the sleeve sleeve, hole or shaft acts on wear or processing tolerance, and the original position is telescopically moved, and then a set is inserted to restore it to its original size.

[0003] There will be corresponding material and hardness requirements for the materials of the sleeve and inner needle; the quality department can use a Rockwell surface hardness tester or a special hardness file to calibrate the surface.

[0004] In the prior art, when testing the sleeve body using a Rockwell surface hardness tester, the sleeve body is generally placed on the upper outer surface of the material table. Since the outer wall of the sleeve body is cylindrical, the sleeve body cannot be stably placed on the upper outer surface of the material table. A technician is required to manually stabilize the sleeve body, which is not convenient enough. For this reason, we propose a detection tool for sleeve inspection. Utility Model Content
