Abstract
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 position. Background Technology
[0002] Steering knuckles are crucial components of automotive steering systems, and their dimensional accuracy is subject to stringent control during manufacturing. In practice, due to the complex structure of steering knuckles, ordinary inspection tools are often insufficient for measuring their assembly dimensions. This is especially true for gooseneck steering knuckles, where the relative position of the ball joint and locking holes is difficult to measure efficiently and accurately. Furthermore, because this positional measurement relies on relative reference positioning, comprehensive inspection tools cannot be used. Coordinate measuring machines (CMMs) are often necessary, but their efficiency limits 100% inspection, requiring sampling. This leads to missed inspections, misjudgments, and even defective steering knuckles reaching the market, preventing proper assembly and causing quality complaints.
[0003] Therefore, developing a quick-access tool for checking the position of the steering knuckle and applying it to actual 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 the position of steering knuckles in order to address the above-mentioned problems. This tool solves the current lack of efficient and accurate measuring tools for the relative position of ball pin holes and locking holes in gooseneck steering knuckles. While using coordinate measuring machines for inspection is possible, it is limited by the efficiency of the equipment and cannot achieve 100% inspection, which can easily lead to missed inspections and misjudgments.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A quick-access steering knuckle position gauge includes a positioning post that engages with the ball joint hole of the steering knuckle. A detection piece is mounted on the positioning post, the thickness of which corresponds to the width of the central slot of the locking hole, allowing the detection piece to slide within the slot. A detection hole is provided on the detection piece corresponding to the locking hole, the position of which corresponds to the locking hole position of a standard steering knuckle product, allowing the detection hole to coincide with the locking hole position within the central slot. The gauge also includes a detection pin that engages with the locking hole, the diameter of which corresponds to the diameters of the locking hole and the detection hole, allowing the detection pin to smoothly pass through the locking hole of the standard steering knuckle product and the detection hole of the detection piece.
[0007] Preferably, a positioning disc is provided on the ball pin end face of the positioning column corresponding to the steering knuckle, for positioning the vertical height of the detection hole.
[0008] Preferably, the detection piece is connected to a positioning post with an adjustable position in the vertical direction. The positioning post has an elongated hole along the axial direction. A slider that slides through the elongated hole is fixedly installed on the detection piece. A positioning stop is provided in the elongated hole corresponding to the slider. A locking screw hole is provided on the slider. A locking bolt passes through the other side of the elongated hole and is screwed into the locking screw hole, so that the detection piece can be locked on the positioning stop.
[0009] Preferably, a drop protection plate is provided corresponding to the detection piece, and the drop protection plate is connected to the positioning plate, with its length covering the height of the detection piece.
[0010] Preferably, the positioning disk is equipped with a handle to facilitate hand operation by the testing personnel.
[0011] The beneficial effects of this utility model are as follows: This utility model uses the ball joint hole of the steering knuckle as the testing benchmark, and opens testing holes at the corresponding standard locking hole positions on the testing piece. Whether the testing pin can smoothly pass through the locking hole and the testing hole serves as the criterion for determining whether the positional accuracy of the ball joint hole and locking hole of the steering knuckle is qualified. This achieves rapid testing of the assembly positional accuracy of the ball joint hole and locking hole of the steering knuckle. The testing process does not require a coordinate measuring machine, overcoming the problem of low testing efficiency in the past. It can achieve 100% full inspection of this testing item, eliminating the problems of missed inspections and misjudgments that are prone to occur with sampling inspections, thus ensuring product quality and safety.

Detailed Implementation
[0018] 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.
[0019] like Figure 1-4 As shown, a quick-access steering knuckle position gauge includes a positioning post 30 that inserts into the ball joint hole 10 of the steering knuckle. A detection piece 40 is provided on the positioning post 30. The thickness of the detection piece 40 corresponds to the width of the central slot 21 of the locking hole 20, allowing the detection piece 40 to slide within the central slot 21. A detection hole 41 is provided on the detection piece 40 corresponding to the locking hole 20. The position of the detection hole 41 corresponds to the locking hole 20 of a standard steering knuckle product, allowing the detection hole 41 to coincide with the locking hole 20 within the central slot 21. It also includes a detection pin 50 that inserts into the locking hole 20. The diameter of the detection pin 50 corresponds to the diameters of the locking hole 20 and the detection hole 41, allowing the detection pin 50 to smoothly pass through the locking hole 20 of the standard steering knuckle product and the detection hole 41 of the detection piece 40. The fit tolerances of the positioning pin 30 and the ball pin hole 10, and the fit tolerances of the detection pin 50 and the locking hole 20 and the detection hole 41 can be specifically configured according to actual testing requirements. The positional accuracy of the positioning pin 30 and the detection hole 40 can be calibrated and measured by a coordinate measuring machine.
[0020] During use, the inspector holds the inspection tool and inserts the positioning pin 30 into the ball pin hole 10 of the steering knuckle to be inspected. Simultaneously, the inspection piece 40 on the inspection pin passes through the central slot 21 of the locking hole 20, and the inspection hole 41 is aligned with the locking hole 20. Then, the inspection pin 50 is inserted into the locking hole 20 to check the relative position of the locking hole 20 and the ball pin hole 10. If the inspection pin 50 can smoothly pass through the locking hole 20 and the inspection hole 41 on the inspection piece 40, it can be determined that the relative position of the locking hole 20 and the ball pin hole 10 of the inspected steering knuckle meets the requirements and can satisfy normal assembly needs. If the inspection pin 50 cannot smoothly pass through the inspection hole 41, it indicates that the relative position of the locking hole 20 and the ball pin hole 10 of the inspected steering knuckle is out of tolerance and cannot meet assembly requirements. This embodiment uses the ball joint hole 10 of the steering knuckle as the inspection benchmark, and opens an inspection hole 41 at the corresponding standard locking hole 20 position on the inspection piece 40. Whether the inspection pin 50 can smoothly pass through the locking hole 20 and the inspection hole 41 is used as the criterion for determining whether the positional accuracy of the ball joint hole 10 and the locking hole 20 of the steering knuckle is qualified. This achieves rapid inspection of the assembly positional accuracy of the ball joint hole 10 and the locking hole 20 of the steering knuckle. The inspection process does not require a coordinate measuring machine, overcoming the problem of low inspection efficiency in the past. It can achieve 100% full inspection of this inspection item, eliminating the problems of missed inspections and misjudgments that are prone to occur in sampling inspections, and ensuring product quality and safety.
[0021] In a preferred embodiment, a positioning disc 31 is provided on the positioning post 30 corresponding to the ball pin end face 11 of the steering knuckle product, for vertical height positioning of the detection hole 41. During testing, as the positioning post 30 is inserted into the ball pin hole 10, the positioning disc 31 acts as a travel limit structure for the insertion depth of the positioning post 30. When the lower end face of the positioning disc 31 is in contact with the ball pin end face 11, the detection hole 41 on the detection piece 40 coincides with the standard locking hole 20. The positioning disc 31 facilitates the alignment of the detection hole 41 with the locking hole 20, further simplifying the testing operation.
[0022] Preferably, such as Figure 4 As shown, the detection piece 40 is vertically adjustable via a connecting positioning post 30, allowing the position of the detection hole 41 relative to the detection post to be adjustable to meet the testing requirements of steering knuckle products at different positions. Specifically, the positioning post 30 has an axially extending elongated hole 32. A slider 42, which is slidably connected to the elongated hole 32, is fixedly mounted on the detection piece 40. A positioning stop 33 is provided within the elongated hole 32 corresponding to the slider 42. A locking screw hole 43 is provided on the slider 42. A locking bolt passes through the other side of the elongated hole 32 and is screwed into the locking screw hole 43, thus locking the detection piece 40 onto the positioning stop 33. When it is necessary to adjust the position of the detection hole 41, loosen the locking bolt to allow the slider 42 to slide within the elongated hole 32 to adjust to a suitable position, and then retighten the locking bolt to complete the hole position adjustment.
[0023] Preferably, a drop guard 60 is provided corresponding to the detection piece 40 to protect the inspection tool from damage and deformation during accidental drops or impacts. The drop guard 60 is connected to the positioning plate 31, and its length covers the height of the detection piece 40. In the event of an accidental drop, the drop guard 60 will effectively prevent the detection piece 40 from hitting the ground, thus preventing damage and deformation.
[0024] Preferably, in order to facilitate handheld testing by testing personnel, the positioning disk 31 is connected to a handle 70, which facilitates the testing operation.
[0025] 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.
