Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a checking tool with integrated hub cap groove and cap opening positioning hole. Background Art

[0002] The hub cap slot and locating hole are the key assembly dimensions of the hub cap, and their production and process inspection and monitoring play a vital role. At present, most of them use separate inspection tools to detect the cap opening diameter and the depth of the hub cap slot, and the depth of the locating hole is inspected by ruler. This inspection method is not only costly, but also has many operating procedures and is prone to errors in the process. It also affects the efficiency of manual inspection, especially the process inspection of the locating hole product is inconvenient. Utility Model Content

[0003] The utility model aims to provide a low-cost, high-efficiency, convenient and accurate inspection tool for positioning hole products.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a checking fixture with integrated wheel hub cap groove and cap opening positioning hole, including a cap opening diameter detection structure, the cap opening diameter detection structure includes a cap opening diameter detection through end and a cap opening diameter detection stop end, a cap opening diameter detection stop end is fixedly installed between the cap opening diameter detection through end and the cap opening diameter detection stop end, a cap groove depth lower difference detection surface and a cap groove depth upper difference detection surface are fixedly installed on the cap opening diameter detection through end, and an anti-interference conformal surface at the cap opening positioning hole and a positioning hole depth detection pin are fixedly installed on the side of the cap opening diameter detection through end.

[0005] The cap diameter detection through end and the cap diameter detection stop end are connected by a handle and connected by a fixing screw column.

[0006] Compared with the prior art, the utility model has the beneficial effect that the positioning hole product of the utility model can simultaneously detect the depth of the cap groove, the diameter of the cap opening, and the diameter and depth of the positioning hole.

DETAILED DESCRIPTION

[0011] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0012] Example: Figure 1-Figure 3 A wheel hub cap groove and cap opening positioning hole integrated inspection fixture is shown, including a cap opening diameter detection structure, the cap opening diameter detection structure includes a cap opening diameter detection through end 1 and a cap opening diameter detection stop end 2, a cap opening diameter detection stop end 3 is fixedly installed between the cap opening diameter detection through end 1 and the cap opening diameter detection stop end 2, a cap opening depth lower difference detection surface 4 and a cap opening depth upper difference detection surface 5 are fixedly installed on the cap opening diameter detection through end 1, and an anti-interference conformal surface 6 at the cap opening positioning hole and a positioning hole depth detection pin 7 are fixedly installed on the side of the cap opening diameter detection through end 1.

[0013] The cap opening diameter detection through end 1 and the cap opening diameter detection stop end 2 are connected through a handle 3 and connected by a fixing screw column 8.

[0014] The working principle is as follows: 1. The through end 1 of the cap opening diameter detection can detect the lower difference line of the cap opening diameter. 2. The stop end 2 of the cap opening diameter detection can detect the upper difference line of the cap opening. 3. The upper difference detection surface 5 of the cap groove depth on the stop end surface can detect the upper difference line of the cap groove depth. 4. The lower difference detection surface 4 of the cap groove depth on the stop end surface can detect the lower difference line of the cap groove depth. 5. The depth detection nail 7 of the positioning hole on the right side of the through end 1 of the cap opening diameter detection can detect the depth and diameter of the positioning hole product.
