Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transmission, in particular to a quick inspection tool for a gearbox rotating rod. Background Art
[0002] The rotating rod is one of the components of the forklift gearbox. Its structure is L-shaped, and the height dimension of 90 (0, -0.2) mm is the key dimension of the part. The common method is to use a depth micrometer as a measuring tool to obtain the required dimension data by measuring the indirect dimension L1 and calculating. When measuring the indirect dimension L1, the measuring surface of the measuring tool is leveled against the base surface B, and the measuring head contacts the base surface A to observe the measurement data. However, because the base surface A is a cylindrical surface, the depth micrometer measuring head is not in contact with the base surface A. The cylindrical surface contact belongs to the contact between the surface and the line, and the contact area between the depth micrometer measuring surface and the base surface A is small; therefore, this measurement method has problems such as inaccurate measurement data, high risk of manual conversion errors, and low measurement efficiency. It needs to be improved, and for this purpose, a gearbox rotating rod quick inspection fixture is designed. Utility Model Content
[0003] The utility model aims to solve one of the technical problems in the related art at least to a certain extent. To this end, one purpose of the utility model is to provide a quick detection fixture for a gearbox rotating rod, which can achieve quick determination, simple operation and high detection efficiency.
[0004] The gearbox rotating rod quick check fixture proposed by the utility model comprises a rotating rod and a quick check fixture body, the bottom side wall of which is provided with a through hole, and the top of which is provided with a stepped groove, which divides the top lower surface of the quick check fixture body into a through end and a stop end.
[0005] Preferably, the rotating rod comprises a rotating handle and an assembly end, and the rotating handle is movably mounted on a side wall of the assembly end.
[0006] Preferably, the assembly end is movably plugged into the through hole.
[0007] Preferably, the rotating handle is in trial contact with the top lower surface of the quick test fixture.
[0008] Preferably, the quick check fixture body is an L-shaped structure.
[0009] Preferably, the height value of the stepped groove is equal to the allowable error value of the rotating rod.
[0010] The beneficial effects of the utility model are:
[0011] 1. Simple structure, low production cost and good practicality;
[0012] 2. It can directly know whether the required key dimensions are within the design tolerance range, quickly determine whether they are qualified or not, omit the calculation process, and reduce manual conversion errors;
[0013] 3. The operation is simple and the detection efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a schematic diagram of the main structure of the quick inspection fixture of the gearbox rotating rod quick inspection fixture proposed by the utility model.
[0015] Figure 2 The utility model is a schematic diagram of the assembly inspection of the gearbox rotating rod quick inspection fixture.
[0016] In the figure: 1, quick check fixture body; 2, rotating rod; 11, through end; 12, stop end; 13, through hole. DETAILED DESCRIPTION
[0017] Reference Figure 1-2 The gearbox rotating rod quick check fixture comprises a rotating rod 2 and a quick check fixture body 1. A through hole 13 is opened on the bottom side wall of the quick check fixture body 1. A stepped groove is opened on the top of the quick check fixture body 1. The stepped groove divides the top lower surface of the quick check fixture body 1 into a through end 11 and a stop end 12.
[0018] The rotating rod 2 comprises a rotating handle and an assembly end, wherein the rotating handle is movably mounted on a side wall of the assembly end.
[0019] The assembly end is movably plugged into the through hole 13 .
[0020] Turn the handle to test contact with the top lower surface of the quick check fixture.
[0021] The quick check fixture body 1 is an L-shaped structure.
[0022] The height value of the step groove is equal to the allowable error value of the rotating rod 2.
[0023] When using this device, insert the rotating rod into the quick check fixture. Through hole 13. Based on the size of the part, there are three types of judgments:
[0024] 1. The top base surface of the rotating handle cannot pass through the through end 11, and the height dimension of the part is determined to be greater than 90mm and is unqualified.
[0025] 2. The top base surface of the rotating handle passes through the through end 11 but cannot pass through the stop end 12. The height dimension is determined to be between 90-89.8, which is qualified.
[0026] 3. The top base surface of the rotating handle passes through 11 and the stop end 12, and the height dimension is determined to be less than 89.8, which is unqualified.
