Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a steering column tube testing tool. Background Technology

[0002] The steering column tube is a crucial component connecting the steering wheel and the steering system, transmitting the driver's forces to the steering system. The steering column typically consists of multiple parts, generally connected by welding. Because these parts are prone to deformation during welding, it is necessary to inspect several important assembly dimensions and positional relationships of the column tube. Currently, these critical dimensions are mostly inspected manually. Inspectors use conventional tools such as rulers, protractors, and calipers to check the steering column tube. However, manual inspection is cumbersome, inefficient, and prone to significant errors, especially in the spatial dimensions of positional relationships, making it impossible to guarantee inspection accuracy. Utility Model Content

[0003] The purpose of this utility model is to provide a steering column tube inspection tool, which positions the column tube using a positioning seat and checks whether the core column, waist-shaped insert plate, and insert rod can be smoothly inserted to determine whether the corresponding assembly dimensions and positional relationships are qualified; it is simple to operate and convenient to inspect, and can effectively improve inspection efficiency and inspection quality.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A steering column tube testing tool includes a column tube positioning seat, wherein the column tube positioning seat is provided with a column tube side hole testing component, a first column tube support testing component, and a second column tube support testing component;

[0006] The column tube side hole detection assembly includes a detection core column that can move vertically;

[0007] The first column support detection assembly includes an obliquely movable waist-shaped insert plate;

[0008] The second column support detection assembly includes a rotatable arm and a plug that fits into the end of the arm.

[0009] The present invention is further configured such that: the column tube positioning seat includes a base plate, a left side plate, a left tube seat, a right tube seat and a right side plate vertically fixed on the base plate; a positioning pin is fixed on the left side plate, and the positioning pin can be inserted into the pin hole of the third bracket at the end of the column tube; the left tube seat and the right tube seat are formed with semi-circular holes, and the two semi-circular holes are matched with the outer diameter of the corresponding part of the column tube.

[0010] The present invention is further configured such that: the detection core insert is inserted into a bushing that cooperates with it, the bushing is fixed on a support plate, and the support plate is fixed on a column tube positioning seat;

[0011] The upper protruding end of the detection core column, which passes through the bushing, is formed with a stepped surface. A first spring is clamped between the stepped surface and the support plate. The first spring provides a supporting force to the detection core column, giving it a certain initial height. Furthermore, the detection core column can automatically move upward and reset after being pressed down, facilitating the detection process.

[0012] The present invention is further configured such that: the waist-shaped insert plate includes an integrally formed small-diameter waist-shaped section and a large-diameter waist-shaped section; the small-diameter waist-shaped section is inserted into the waist-shaped hole, thereby detecting the position of the waist-shaped hole;

[0013] The large-diameter waist-shaped section is inserted into the waist-shaped insertion hole of the support block, and the support block is fixed on the column tube positioning seat. The waist-shaped insertion hole is used for positioning and guiding the waist-shaped insertion plate. The waist-shaped insertion plate is equipped with large-diameter and small-diameter sections, which can limit the insertion amount of the small-diameter section, facilitating the inspection work.

[0014] This invention is further characterized in that a pair of recessed holes are formed at the end of the larger diameter waist-shaped section away from the smaller diameter waist-shaped section. The recessed holes facilitate the movement of the waist-shaped insert plate and reduce the risk of slippage when workers move the plate.

[0015] The present invention is further configured such that the recessed hole is a ball-and-socket hole. The ball-and-socket hole facilitates the insertion of the worker's finger and increases finger comfort.

[0016] The present invention is further configured such that the support arm is in the shape of a rectangular strip;

[0017] The end of the support arm away from the insert rod is formed into a semi-cylinder, and a support shaft coaxially arranged inside the semi-cylinder is sleeved therein; the support shaft is fixed on the support, and the support is fixedly connected to the support block;

[0018] The support has a rectangular groove formed on it, and the lower sidewall of the support arm can rest against the bottom surface of the rectangular groove.

[0019] The bottom surface of the rectangular groove can support the arm after it is flipped, thus facilitating the positioning of the arm. The fixed position of the arm is necessary to ensure the position of the insertion rod.

[0020] The outstanding effect of this utility model is:

[0021] Compared with existing technologies, this method uses a positioning seat to position the column tube and checks whether the core column, waist-shaped insert plate, and insert rod can be smoothly inserted to determine whether the corresponding assembly dimensions and positional relationships are qualified. It is also simple to operate and convenient to test, which can effectively improve the testing efficiency and quality. Attached Figure Description

[0032] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0033] The following is for reference Figures 1 to 5 The present invention will be described as follows:

[0034] A steering column tube inspection tool includes a column tube positioning seat 10, on which a column tube side hole inspection assembly 20, a first column tube support inspection assembly 30, and a second column tube support inspection assembly 40 are provided. The column tube positioning seat 10 includes a base plate 101, a left side plate 102, a left tube seat 103, a right tube seat 104, and a right side plate 105 vertically fixed to the base plate 101. A positioning pin 106 is fixed on the left side plate 102, which can be inserted into the pin hole 907 of the third support 906 at the end of the column tube 90. Semi-circular holes are formed on the left tube seat 103 and the right tube seat 104, and these two semi-circular holes mate with the outer diameter of corresponding parts of the column tube 90. The semi-circular holes are used for positioning the center height of the column tube, and the positioning pins prevent the column tube from rotating. Finally, a detection core is inserted into the side hole, thereby constraining all degrees of freedom of the column tube.

[0035] The column tube side hole detection assembly 20 includes a vertically movable detection core 201; the detection core 201 is inserted into a bushing 202 that cooperates with it, the bushing 202 is fixed on a support plate 203, and the support plate 203 is fixed on the column tube positioning seat 10.

[0036] The detection core 201 has a stepped surface 204 formed on its upper protruding end through the bushing 202. A first spring 205 is held between the stepped surface 204 and the support plate 204. The first spring provides a supporting force to the detection core, giving it a certain initial height. Furthermore, the detection core can automatically move upwards and reset after being pressed down, facilitating the detection process.

[0037] The first column tube support detection assembly 30 includes a waist-shaped insert plate 301 that can move obliquely; the waist-shaped insert plate 301 includes an integrally formed small-diameter waist-shaped section 302 and a large-diameter waist-shaped section 303; the small-diameter waist-shaped section 302 is inserted into the waist-shaped hole 903, thereby detecting the position of the waist-shaped hole;

[0038] The large-diameter waist-shaped section 303 is inserted into the waist-shaped insertion hole 305 of the support block 304, and the support block 304 is fixed on the column tube positioning seat 10. The waist-shaped insertion hole is used for positioning and guiding the waist-shaped insertion plate. The waist-shaped insertion plate is designed with large-diameter and small-diameter sections to limit the insertion amount of the small-diameter section, which facilitates the inspection work. A pair of concave holes 306 are formed at the end of the large-diameter waist-shaped section 303 away from the small-diameter waist-shaped section 302. The concave holes facilitate the movement of the waist-shaped insertion plate and reduce the risk of slippage when the operator moves the waist-shaped insertion plate. The concave holes 306 are ball-and-socket holes, which facilitate the insertion of the operator's fingers and increase finger comfort.

[0039] The second column support detection assembly 40 includes a rotatable support arm 401 and an insertion rod 402 inserted into the end of the support arm 401, wherein the support arm 401 is rectangular strip-shaped;

[0040] The end of the support arm 401 away from the insertion rod 402 is formed with a semi-cylinder 403, and a support shaft 404 coaxially arranged inside the semi-cylinder 403; the support shaft 404 is fixed on the support 405, and the support 405 is fixedly connected to the support block 304.

[0041] A rectangular groove 406 is formed on the support 405, and the lower sidewall of the support arm 401 can abut against the bottom surface of the rectangular groove 406.

[0042] The bottom surface of the rectangular groove can support the arm after it is flipped, thus facilitating the positioning of the arm. The fixed position of the arm is necessary to ensure the position of the insertion rod.

[0043] During testing, the column tube 90 is positioned on the column tube positioning seat. Then, the testing core 201 is pressed down and inserted into the side hole 901 of the column tube 90. This serves two purposes: first, it allows for the detection of the position and size of the side hole; second, it allows for further positioning of the column tube 90. Then, the waist-shaped insert plate 301 is moved and inserted into the waist-shaped hole 903 of the first bracket 902 of the column tube 90. The support arm 401 is flipped to be above the second bracket 904 of the column tube 90. Then, the insert rod 402 is moved so that it is inserted into the small hole 905 of the second bracket 904, thereby completing the detection of the position of the side hole, the first bracket, and the second bracket.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
