Abstract

This utility model discloses an integrated multi-functional inspection tool for a steering column. The steering column is welded from a disc bracket, a steel pipe, and an L-shaped small bracket. The disc bracket has evenly distributed perforations around its circumference, and the small bracket also has perforations machined on its vertical plane. The inspection tool consists of a base plate, an inlaid go gauge, a fixing pin, and an anti-misalignment pin. The inlaid go gauge and fixing pin inspect the disc bracket, the anti-misalignment pin inspects the small bracket, and the overall height detection pin measures the height of the steel pipe. When issues such as the small bracket being placed backwards, missing perforations, missing perforations in the disc bracket, dimensional deviations in the circular step, or missing processing steps occur, multiple inspection components work together to report non-compliance, generating a high-intensity warning. This inspection tool, through its ingenious structural design, achieves accurate detection of various quality problems in the steering column. Compared with traditional inspection methods, it improves inspection accuracy and efficiency, reduces production costs, and effectively identifies and isolates non-conforming products.

Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to an integrated multi-functional inspection tool for steering column. Background Technology

[0002] In the manufacturing process of automotive steering columns, the steering column is typically welded from steel tubes, a disc bracket, and a small bracket. However, during the welding process, issues may arise such as incorrect placement of the small brackets, missed punching, and the disc bracket itself may have missed punching, deviations in the diameter of the circular step, or omissions in machining processes. Traditional methods of inspecting with ordinary go / no-go gauges rely on the attention and responsibility of workshop inspectors, which carries the risk of failing to effectively identify defective products. This can lead to defective products being mixed into the qualified product warehouse, affecting product quality and production efficiency. Therefore, there is an urgent need for a tool that can accurately and efficiently detect various quality problems in steering columns. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes an integrated multi-functional inspection tool for steering columns.

[0004] This utility model proposes an integrated multi-functional inspection tool for steering columns, comprising:

[0005] Steering column: The steering column includes a disc support, on the top side of which a steel pipe is vertically welded. The axis of the steel pipe coincides with the geometric center of the disc support. The disc support is provided with three sets of circumferentially distributed through-holes.

[0006] Two sets of L-shaped small supports are symmetrically arranged on the top of the disc support, respectively on both sides of the steel pipe. The small supports are formed by bending metal plates. One plane is rigidly connected to the top surface of the disc support by welding, and the other vertical plane extends vertically to the top of the disc support. The vertical planes of the two sets of small supports are in the same reference plane, and punching holes are processed on the vertical plane.

[0007] Inspection tool: The inspection tool includes a base plate, on the upper side of which is provided an inlaid go gauge for checking whether the diameter of the circular step of the disc bracket of the steering column is correct; the disc bracket can be snapped into the inlaid go gauge;

[0008] The inlaid gauge is provided with three sets of circumferentially distributed fixing pins for detecting whether there are any missing punches on the disc support. The three sets of punches on the disc support can be engaged with the three sets of fixing pins.

[0009] A pin fixing plate is vertically connected to one side of the top of the inspection tool. A pin insert is provided at the top of the pin fixing plate. A total height detection pin is horizontally connected to the side wall of the pin insert, which is used to detect whether the total height dimension of the steel pipe is correct.

[0010] A positioning block is vertically installed on the other side wall of the base plate. Two sets of parallel anti-misalignment pins are horizontally installed on the side wall of the positioning block. These are used to detect whether the placement direction of the two sets of L-shaped brackets is correct during welding and whether there are any missing holes in the brackets.

[0011] Preferably, the tail of the anti-misalignment pin is threaded, and the tail end of the anti-misalignment pin is threadedly connected to the positioning block. The threaded part of the anti-misalignment pin is threadedly connected with two sets of nuts. When the anti-misalignment pin is installed on the positioning block, the two sets of nuts are located on both sides of the positioning block, which can effectively prevent the anti-misalignment pin from loosening and moving back and forth during long-term use.

[0012] Preferably, when the steering column is engaged in the fixture, the tops of the two sets of anti-misalignment pins are located at the upper-middle position of the punch holes of the two sets of small brackets.

[0013] Preferably, the inner diameter of the inlaid go gauge is adapted to the standard diameter of the circular step of the disc bracket. When the diameter of the circular step of the disc bracket is too large or the machining process is omitted, the disc bracket cannot be engaged in the inlaid go gauge.

[0014] Preferably, the pin insert is provided with a mounting hole for installing the total height detection pin, and the diameter of the mounting hole is interference-fitted with the outer diameter of the total height detection pin to ensure the stability of the total height detection pin installation.

[0015] The integrated multi-functional inspection tool for steering columns proposed in this utility model has the following technical effects:

[0016] High-accuracy testing: Through the coordinated work of multiple testing components, when any of the following problems occur in the steering column, such as the small bracket being placed backwards, missing punching holes, missing punching holes in the disc bracket, dimensional deviation of the circular step, or missing processing steps, it will cause seven testing pins to fail to pass the product simultaneously. This will give the inspector a strong warning, forcing the inspector to identify the non-conforming product, avoid missed inspections, and greatly improve the accuracy of testing.

[0017] The anti-mistake pin for the small bracket is positioned slightly above the center of the small bracket hole, providing sufficient height allowance for the product to be lifted past the fixing pin and make contact with the anti-mistake pin, ensuring a smooth testing process. At the same time, the thread on the anti-mistake pin can be adjusted to its front and back position, allowing the anti-mistake pin to be smoothly inserted into the small bracket hole without interfering with the product insertion, thus ensuring the reliability and stability of the testing.

[0018] Multifunctional integration: This inspection tool can simultaneously detect multiple quality problems of the steering column, integrating multiple inspection functions into one. Compared with traditional single-function inspection tools, it reduces inspection steps and time, improves inspection efficiency, and reduces production costs.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figures 1-4 The diagram shows an integrated multi-functional inspection tool for a steering column. The steering column includes a disc bracket 101, with a steel pipe 102 vertically welded to the top side of the disc bracket 101. The axis of the steel pipe 102 coincides with the geometric center of the disc bracket 101. The disc bracket 101 has three sets of circumferentially distributed through-holes. Two sets of L-shaped small brackets 103 are symmetrically arranged on the top of the disc bracket 101, respectively arranged on both sides of the steel pipe 102. The small brackets 103 are formed by bending metal sheets. One plane is rigidly connected to the top surface of the disc bracket 101 by welding, and the other vertical plane extends vertically above the disc bracket 101. The vertical planes of the two sets of small brackets 103 are in the same reference plane, and punches are machined on this vertical plane.

[0029] The integrated multifunctional inspection tool of the present invention is assembled from a base plate 1, a pin fixing plate 2, an anti-misalignment pin 6, a positioning block 3, a pin insert 4, a total height detection pin 5, a small bracket 103, an anti-misalignment pin 6, a disc bracket 101, a fixing pin 7, an inlaid go gauge 8, and an adjusting nut 9. The base plate 1 has an inlaid go gauge 8 on its upper side for measuring the disc bracket 101 of the steering column. The disc bracket 101 can be snapped into the inlaid go gauge 8. The inlaid go gauge 8 has three sets of circumferentially distributed disc bracket 101 fixing pins 7 for detecting three sets of punches on the disc bracket 101. The three sets of punches on the disc bracket 101 can be snapped into the three sets of fixing pins 7. One side of the gauge is vertically connected to a pin fixing plate 2 via an adjusting nut 9. The top of the pin fixing plate 2 is provided with a pin insert 4. The side wall of the pin insert 4 is horizontally connected to a total height detection pin 5 for measuring the height of the steel pipe 102. The other side wall of the base plate 1 is vertically installed with an anti-misalignment pin 6 positioning block 3. The side wall of the anti-misalignment pin 6 positioning block 3 is horizontally installed with two sets of parallel small brackets 103 anti-misalignment pins 6. The anti-misalignment pin 6 of the small bracket 103 is designed at a slightly above-center position on the hole of the corresponding product's small bracket 103, and the anti-misalignment pin 6 of the small bracket 103 is threaded for adjusting the front and rear position of the small bracket 103 anti-misalignment pin 6. When any of the following situations occur in the steering column: the small bracket 103 is installed backwards, the small bracket 103 has a missing hole punch, the three holes on the disc bracket 101 have a missing hole punch, the diameter of the circular step of the disc bracket 101 is too large, or the disc bracket 101 has missed a machining process, the anti-misalignment pin 6 of the small bracket 103, the fixing pin 7 of the disc bracket 101, and the overall height detection pin 5 will not be able to cooperate with the corresponding parts, and the circular step of the disc bracket 101 will not be able to pass through the inlaid go gauge 8, thereby realizing the detection and identification of unqualified products.

[0030] When using this integrated multi-functional inspection tool to inspect the steering column, place the steering column to be inspected on the base plate 1 of the inspection tool, try to make the disc bracket 101 snap into the inlaid go gauge 8, and connect the three sets of punches on the disc bracket 101 to the three sets of disc bracket 101 fixing pins 7 on the inlaid go gauge 8.

[0031] During placement, if the small bracket 103 is placed in the correct orientation and there are no missing holes, the holes on the vertical surface of the small bracket 103 can pass smoothly through the anti-misalignment pin 6 on the positioning block 3. If the small bracket 103 is placed in reverse or has missing holes, there will be no holes on the vertical surface of the small bracket 103. The small bracket 103 will be blocked by the anti-misalignment pin 6, causing the disc bracket 101 to be unable to continue to the point where it matches the fixing pin 7. The three holes on the disc bracket 101 will not be able to fit the corresponding three fixing pins 7. At this time, the lower surface of the disc bracket 101 will be lifted by the fixing pin 7.

[0032] When the disc support 101 is lifted, the steel pipe 102 welded to the disc support 101 will be higher than the plane where the total height detection pin 5 is located, thus preventing the total height detection pin 5 from being inserted into the upper end face of the steel pipe 102. At the same time, the circular step of the disc support 101 cannot pass into the inlaid go gauge 8. This means that if there is an error such as the small support 103 being welded backwards or having a hole not punched, the inspector will receive seven non-conformity warnings simultaneously: the small support 103 anti-mistake pin 6 cannot pass through the small support 103, the three fixing pins 7 cannot pass through the hole on the disc support 101, the total height detection pin 5 cannot pass through the upper end face of the steel pipe 102, and the circular step of the disc support 101 cannot pass into the inlaid go gauge 8. The inspector can then promptly determine that the product is non-conforming and place it in the non-conforming product box.

[0033] If the three holes on the disc bracket 101 are not punched (no holes), the diameter of the circular step on the disc bracket 101 is too large, or the machining process on the disc bracket 101 is omitted (no circular step), the product will also be unable to pass through the three fixing pins 7 or the inner go gauge 8. The lower plane of the disc bracket 101 will be lifted by the fixing pins 7 or the inner go gauge 8, causing the lifted steel pipe 102 to be higher than the plane where the total height detection pin 5 is located, blocking the insertion of the total height detection pin 5, thus determining that the total height of the product is unqualified. Through this significant secondary warning of unqualified total height, the inspector can effectively identify the above three unqualified situations of the disc bracket 101, ensuring that unqualified products do not enter the qualified product warehouse.

[0034] In addition, before actual testing, the front and rear positions of the anti-mistake pin 6 on the small bracket 103 can be adjusted according to the product specifications using the threads on the anti-mistake pin 6, so that the depth of the front end of the anti-mistake pin 6 inserted into the small bracket 103 is just right, which will not affect the product placement, and will allow the inspector to clearly identify whether the small bracket 103 is inserted into the anti-mistake pin 6, thus ensuring the smooth progress of the testing work.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
