Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to a quick inspection tool for steering knuckle press-fit holes. Background Technology

[0002] As a core component of the automotive steering system, the machining accuracy of the steering knuckle directly affects vehicle handling and safety. Therefore, strict control over the various machining dimensions of the steering knuckle during production is essential to ensure product quality. Currently, there is a lack of efficient and convenient measurement tools for controlling the dimensional control of the fillet radius and chamfer of the steering knuckle press-fit holes. Traditional measurement methods typically rely on coordinate measuring machines (CMMs) for 3D point cloud analysis. This method is cumbersome, time-consuming, and inefficient, failing to meet the rapid inspection needs of production lines. Furthermore, CMMs are expensive, have limited product coverage, cannot achieve batch inspection of steering knuckles, and are prone to missed inspections and misjudgments, resulting in high quality risks.

[0003] Therefore, developing a new type of steering knuckle press-fit hole inspection tool for practical production is an urgent problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a quick inspection tool for steering knuckle press-fit holes to address the above-mentioned problems, thereby solving the problems of long time occupied by coordinate measuring equipment, low inspection efficiency, easy omissions and misjudgments, and high quality risks in the existing steering knuckle press-fit hole inspection process.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A quick inspection tool for steering knuckle press-fit holes includes an inspection disc for inspecting the fillet size of steering knuckle press-fit holes. The outer diameter of the inspection disc is made to correspond to the fillet size of the steering knuckle press-fit hole. The thickness of the inspection disc is consistent with the fillet height, so that the two end faces of the inspection disc are flush with the edge of the standard fillet.

[0007] Preferably, it also includes a test gauge for detecting the diameter of the press-fitting hole. The test gauge is a cylindrical structure set according to the diameter of the press-fitting hole. The test gauge includes a test go gauge with a diameter set to a lower tolerance corresponding to the diameter of the press-fitting hole, and a test stop gauge with a diameter set to a higher tolerance corresponding to the diameter of the press-fitting hole.

[0008] Preferably, the outer sleeve of the inspection gauge is coaxially provided with an inspection sleeve, the inspection sleeve is axially slidably connected to the inspection gauge, and the outer diameter of the inspection sleeve is provided with a stop detection part corresponding to the stop diameter of the press-fit hole, for detecting the stop size of the press-fit hole.

[0009] Preferably, the length of the inspection gauge is set to correspond to the depth dimension of the press-fit hole, and the tail end of the inspection sleeve is provided with an inspection recess and an inspection protrusion respectively corresponding to the depth dimension tolerance of the press-fit hole. The inspection recess is set to correspond to the lower tolerance of the depth dimension of the press-fit hole, and the inspection protrusion is set to correspond to the upper tolerance of the depth dimension of the press-fit hole, so that the end face of the tail end of the inspection sleeve presents a high-low platform shape.

[0010] Preferably, a limiting bolt is screwed onto the detection sleeve, and a limiting groove is formed at the tail end of the detection gauge corresponding to the limiting bolt. The limiting bolt passes through the detection sleeve and extends into the limiting groove, but the limiting bolt does not press against the limiting groove.

[0011] The beneficial effects of this utility model are as follows: By setting up a detection disc for detecting the fillet radius of the steering knuckle press-fit hole, and detection gauges and sleeves for detecting the hole diameter, depth, and stop dimensions, this utility model achieves rapid full-size detection of the steering knuckle press-fit hole. It eliminates the cumbersome operation of traditional three-dimensional point cloud analysis using coordinate measuring equipment, avoids prolonged occupation of the coordinate measuring equipment, saves detection time, and improves detection efficiency. The convenient and rapid detection method provided by this utility model can achieve batch full inspection of the press-fit holes of steering knuckle products, reducing the problems of missed inspections and misjudgments, and lowering product quality risks.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] like Figure 1-2As shown, a quick inspection tool for steering knuckle press-fit holes includes an inspection disc 20 for detecting the fillet radius r of the steering knuckle press-fit hole 10. The outer diameter of the inspection disc 20 is custom-made to conform to the fillet radius r of the steering knuckle press-fit hole 10, allowing the outer edge of the inspection disc 20 to fit tightly against the fillet radius of the standard-sized press-fit hole. The thickness of the inspection disc 20 is consistent with the fillet height, ensuring that the two end faces of the inspection disc 20 are flush with the edge of the standard fillet radius. During inspection, the inspection disc 20 is placed over the fillet end of the press-fit hole to be inspected. If the inspection disc 20 can smoothly fit into the fillet radius of the press-fit hole, and the outer end face of the inspection disc 20 is flush with the edge of the fillet radius, then the fillet radius r of the inspected steering knuckle press-fit hole 10 can be determined to be qualified. This achieves quick detection of the fillet radius r of the steering knuckle press-fit hole 10.

[0018] In a preferred embodiment, the inspection fixture further includes a test gauge for detecting the diameter D1 of the press-fit hole. The test gauge is a cylindrical structure corresponding to the diameter D1 of the press-fit hole. The test gauge includes a GO gauge 31 with a diameter set to the lower tolerance of the diameter D1, and a GO gauge 32 with a diameter set to the upper tolerance of the diameter D1. During inspection, the GO gauge 31 and the GO gauge 32 are inserted into the press-fit hole sequentially. If the GO gauge 31 can be inserted smoothly into the press-fit hole, while the GO gauge 32 cannot be inserted, it indicates that the actual diameter D1 of the press-fit hole under inspection is within the tolerance range of the standard diameter D1, and the diameter D1 of the press-fit hole 10 of the steering knuckle under inspection can be determined to be qualified.

[0019] Preferably, a test sleeve 40 is coaxially provided on the outer side of the test gauge 31. The test sleeve 40 is axially slidably connected to the test gauge 31. The outer diameter of the test sleeve 40 is provided with a stop detection part 41 corresponding to the stop diameter of the press-fit hole, which is used to detect the stop size D2 of the press-fit hole. The diameter of the stop detection part 41 is slightly smaller than the stop diameter of the press-fit hole. During the test, after the test gauge 31 is successfully inserted into the press-fit hole, the test sleeve 40 is pushed so that the stop detection part 41 attempts to fall into the stop portion of the press-fit hole. If the stop detection part 41 can fall into the stop portion smoothly and the front end face of the stop detection part 41 fits tightly with the bottom surface of the stop, then the stop size D2 of the press-fit hole can be determined to be qualified.

[0020] Preferably, the length L1 of the inspection gauge is set to correspond to the depth dimension H of the press-fit hole, and is used to inspect the depth dimension H of the press-fit hole. Specifically, the tail end of the inspection sleeve 40 is provided with an inspection recess 42 and an inspection protrusion 43 corresponding to the tolerance of the depth dimension H of the press-fit hole. Among them, the inspection recess 42 is set to correspond to the lower tolerance of the depth dimension H of the press-fit hole, and the inspection protrusion 43 is set to correspond to the upper tolerance of the depth dimension H of the press-fit hole, so that the end face of the tail end of the inspection sleeve 40 has a high-low platform shape. During inspection, the test gub 31 is inserted into the press-fit hole, and the front end of the test gub 31 abuts against the test disc 20. The test sleeve 40 is pushed into the stop of the press-fit hole. At this time, the position of the tail end of the test gub 31 relative to the test recess 42 and the test protrusion 43 is checked. If the tail end of the test gub 31 protrudes from the test recess 42 and is recessed in the test protrusion 43, it indicates that the actual depth dimension H of the press-fit hole is within the tolerance range of the standard dimension, and the depth dimension H of the press-fit hole 10 of the inspected steering knuckle can be determined to be qualified. In this embodiment, the depth dimension H of the press-fit hole = the length L1 of the test gub - the length L2 of the test sleeve.

[0021] Preferably, a limiting bolt 44 is screwed onto the detection sleeve 40, and a limiting groove 33 is formed at the tail end of the detection gauge 31 corresponding to the limiting bolt 44. The limiting bolt 44 passes through the detection sleeve 40 and extends into the limiting groove 33, and the limiting bolt 44 does not press against the limiting groove 33, which is used to limit the sliding stroke of the detection sleeve 40 and the detection gauge 31 to prevent them from separating.

[0022] This invention achieves rapid, full-size inspection of the steering knuckle press-fit hole 10 by using an inspection disc 20 for detecting the fillet radius r of the hole 10, and an inspection gauge and inspection sleeve 40 for detecting the hole diameter D1, depth H, and stop dimension D2. This eliminates the cumbersome operation of traditional three-dimensional point cloud analysis using coordinate measuring machines (CMMs), avoids prolonged occupation of CMM equipment, saves inspection time, and improves inspection efficiency. The convenient and rapid inspection method provided by this invention enables batch full inspection of the press-fit holes in steering knuckle products, reducing the problems of missed inspections and misjudgments, and lowering product quality risks.

[0023] The above-disclosed embodiments are merely specific examples of this utility model, but this utility model is not limited thereto. For those skilled in the art, any modifications made without departing from the principle of this utility model should be considered as protected by this utility model.
