Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings.

[0010] Such as figure 1 As shown, a product inner hole 90-degree quick inspection jig includes a jig body 1, the jig body 1 is provided with an installation groove 2 for placing the product to be tested, and the jig body 1 is also provided with There are two first through-slots 3 and second through-slots 4 that communicate with the installation groove 2 and are perpendicular to each other. After putting the product to be tested into the installation groove 2, insert two round rods with the same diameter as the inner hole from the first through groove 3 and the second through groove 4 into the inner hole of the product to be tested, if two If the round rods can be inserted at the same time, it means that the product is qualified.

[0011] The width of the first through groove 3 is consistent with the diameter of the inner hole, and the width of the second through groo...

Abstract

The invention discloses a quick inspection jig for a product inner hole 90-degree angle. The jig comprises a jig main body, wherein the jig main body is provided with an installation groove used for holding a product to be inspected, the jig main body is further provided with a first through groove and a second through groove, and the first through groove and the second through groove are communicated with the installation groove and are vertical to each other. The jig solves the problems that in the prior art, inspection for the product inner hole 90-degree angle is difficult and efficiency is not high, can quickly inspect whether the included angle of two inner holes in the product to be inspected meets requirements, greatly improves inspection efficiency and reduces labor cost of workers.

Description

technical field [0001] The invention relates to a jig for quickly inspecting a 90-degree angle in a product inner hole, and belongs to the technical field of machinery. Background technique [0002] In the production process of our factory, there is a product that needs to be provided with two mutually perpendicular inner holes on its side. After drilling it through the machine tool, it is necessary to check whether the sharp angle between the two through holes is 90 degrees or the tolerance is within the allowable range. The existing detection method is manual measurement with tools such as rulers, which is not only inefficient, but also prone to errors. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fixture for quickly inspecting the 90-degree angle of the inner hole of the product, which can quickly detect whether the included angle between the two inner holes of the product meets the requirements. [000...
