[0002] With the continuous innovation in the automotive industry, OEM (Original Equipment Manufacturer) factories for various automotive parts have sprung up like mushrooms after rain. These factories exhibit significant differences in manufacturing technology and product quality. The steering column, a crucial component for vehicle operation, is typically constructed from multiple welded parts. During welding, these parts undergo thermal expansion and contraction, causing deformation. If their dimensions and positional relationships change, the OEM cannot install them smoothly later. Existing upper column inspection tools generally rely on calipers, plug gauges, and other inspection equipment, resulting in complex, inefficient, and inaccurate inspection procedures.

[0026] 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.

[0027] The following is for reference Figures 1 to 6 The present invention will be described as follows:

[0028] A gauge for an upper tube column assembly includes a base plate 1, on which a left support detection component 2, a middle support detection component 3, and a right support detection component 4 are provided; the upper tube column assembly 9 involved in this embodiment includes a base tube 91, a left support 92 and a right support 93 fixed at both ends of the base tube 91, and a middle support 94 and a fourth support 95 fixed in the middle of the base tube 91;

[0029] The left support detection assembly 2 includes a reference positioning block 21, a first detection rod 22 that can move laterally and is fitted onto the reference positioning block 21, and a left detection mandrel 23. A vertically arranged positioning rod 24 is fixed on the reference positioning block 21. The reference positioning block 21 is fixed on the base plate 1. A heightening block 25 is fixed on the reference positioning block 21. A square hole detection rod 26 is fitted onto the heightening block 25. The upper end of the square hole detection rod 26 has a stepped protrusion surface 261, which can prevent the square hole detection hole from falling off. A ball head 221 is fixed to the outer end of the first detection rod 22, which facilitates the movement of the first detection rod.

[0030] The right support detection assembly 4 includes a fixed support block 41, which is fixed on the base plate. A right detection spindle 42 and a plurality of second detection rods 43 that can move laterally are sleeved on the support block 41. The right detection spindle 42 and the second detection rods 43 are fixed on the drive block 44, which can facilitate the movement of the right detection spindle and the second detection rods together, thereby improving the operability of the box.

[0031] The intermediate support detection assembly 3 includes a base block 31, and a movable height detection block 32 is provided above the end of the base block 31. The height detection block 32 is inserted into the support 33, and the support 33 and the base block 31 are fixed on the base plate 1. A plurality of waist-shaped positioning protrusions 34 are fixed on the base block 31.

[0032] The base block 31 is also provided with a fourth support detection assembly 5. The fourth support detection assembly 5 includes a vertical detection rod 51 fixed on the base block 31. A movable insert plate 52 is provided on one side of the upper end of the vertical detection rod 51. A detection groove 53 is formed at the end of the insert plate 52 near the vertical detection rod 51. The insert plate 52 is inserted into the insert plate guide seat 54, and the insert plate guide seat 54 is fixed on the base block 31.

[0033] Working principle: First, align the first hole 921 on the left bracket 92 with the positioning rod 24, and align the waist-shaped hole 941 on the middle bracket 94 with the waist-shaped positioning protrusion 34. Then insert downwards. If the first hole 921 is inserted into the positioning rod and the waist-shaped hole 941 can be inserted into the waist-shaped positioning protrusion 34, it means that these two dimensions are qualified, and the upper tube column assembly is also positioned. If it cannot be inserted, the upper tube column assembly is unqualified.

[0034] The first test rod is moved and inserted into the second hole of the left bracket. If it can be inserted, it means that the position of the left bracket is qualified. If it cannot be inserted, it means that the upper tube column assembly is unqualified.

[0035] Similarly, check whether the left detection mandrel can be inserted into the left end of the base tube 91;

[0036] The drive block moves to the left, which can simultaneously drive the right detection mandrel and the second detection rod to move. Whether the right detection mandrel can be inserted into the right end of the base tube 91 and whether the second detection rod can be inserted into the third hole 931 with the bracket 93, if they can be inserted, it means that the part is qualified; if they cannot be inserted, it means that the upper tube column assembly is unqualified.

[0037] Move the square hole test rod downwards. If the square hole test rod can be inserted into the square hole 911 of the base tube 91, it means that this part is qualified; if it cannot, it means that the upper tube column assembly is unqualified.

[0038] During the process described in step one, check whether the vertical detection rod can be inserted into the fourth hole 951 of the fourth bracket 95. If it can, move the insert plate and check whether the detection slot of the insert plate can be inserted into the fourth bracket. If it can be inserted, it means that the part is qualified. If it cannot be inserted, the upper tube column assembly is unqualified.

[0039] The height detection block can be moved. If the height detection block can be inserted above the lower side plate 942 of the intermediate bracket 94, it means that the part is qualified. If it cannot be inserted, the upper column assembly is unqualified.

[0040] By checking whether each size can be inserted, the relevant dimensions and positional relationships of the upper tube column assembly are inspected. If all parts can be inserted, the upper tube column assembly is considered qualified; if some parts cannot be inserted, it is considered unqualified.

[0041] 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.
