Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a detection tool used for adjusting the height of a handle of a steering column. Background Art

[0002] The adjustment handle is an important component in the car steering system, used to turn on and off the adjustment function of the steering wheel position. When the adjustment handle is turned on, the driver can move the steering wheel to drive the steering column to adjust the front and rear and up and down position of the steering wheel relative to the driver, so that the driver can get a comfortable driving posture. When the adjustment handle is closed, the driver can lock the steering wheel position that has been adjusted by the driver and ensure that the steering wheel and steering column do not move randomly.

[0003] The adjustment handle can realize the lateral displacement of the relative radial and axial positions of the handle cam and the fixed cam by rotating, change the handle clamping shaft system parts, and realize the function of clamping and loosening the entire handle shaft system. When the adjustment handle is rotated to the locking position, the shaft system composed of the adjustment handle, cam, clamping bracket, needle bearing and anti-loosening nut will form a clamping force to ensure that when the adjustment handle is in the locking position, the up and down and front and back positions of the column will not change arbitrarily, ensuring the safety of the driver during driving.

[0004] However, during the industrialization process, the material used for the handle shaft system parts will exceed the elastic limit of the material after multiple adjustments under such a large clamping force. When the soft limit strength is insufficient, there will be a risk of deformation after multiple adjustments or a certain force is applied, resulting in the closing angle of the adjustment handle not meeting the design angle requirements. After the sample in this state is loaded on the vehicle, there will be a problem of insufficient hand space between the adjustment handle and the guard, and there is a risk of pinching the hand.

[0005] In the prototype development stage, the soft limit strength has not been fully verified, and the handle height status of different models of steering columns needs to be confirmed. However, there is currently no tooling for detecting the height of the steering column adjustment handle, and manual measurement is time-consuming and inefficient.

[0006] Therefore, it is necessary to design a detection tool for the height of the steering column adjustment handle, so as to efficiently and conveniently detect the height of the adjustment handle after it is closed during the sample development stage, save measurement time, and reduce the risk of pinching hands caused by insufficient height of the adjustment handle. Summary of the invention

[0007] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a detection tool for the height of a steering column adjustment handle, so that during the prototype development stage, the height of the adjustment handle after closing can be efficiently and conveniently detected, thereby saving measurement time and reducing the risk of pinching the hand due to insufficient height of the adjustment handle.

[0008] In order to achieve the above-mentioned purpose, the utility model is a detection tool for adjusting the height of a steering column handle, comprising a base plate, a mounting block, a column bracket positioning mechanism, a servo housing positioning pin, an upper column tube positioning mechanism, a card base, and a height detection card. The upper column tube positioning mechanism is installed in the front end groove of the base plate, the rear end of the base plate is provided with a mounting block extending outward, the servo housing positioning pin passes through a lug on the surface of the mounting block, a column bracket positioning mechanism is respectively installed on the left and right sides of the top of the base plate, a card base is installed on the right front side of the top of the base plate, two height detection card plates pass through the card base from right to left, and a height difference is provided between the two height detection card plates.

[0009] The pipe column support positioning mechanism comprises a pipe column support positioning seat and a pressure clamp, and the pipe column support positioning seat is provided at the downward pressing position of the pressure clamp.

[0010] The distance between the column bracket positioning seats of the two column bracket positioning mechanisms matches the bracket length of the steering column.

[0011] The upper column tube positioning mechanism includes an upper column tube positioning seat, an upper column tube positioning knob, and a connecting piece. An L-shaped groove is provided on the front side of the upper column tube positioning seat, one end of the L-shaped groove extends to the edge of the upper column tube positioning seat, and a rotatable upper column tube positioning knob is installed on the top of the upper column tube positioning seat. One end of the connecting piece is connected to the bottom of the upper column tube positioning knob, and the other end of the connecting piece is located in the L-shaped groove.

[0012] The installation heights of the two height detection card plates are respectively the upper limit value and the lower limit value of the height of the adjustment handle.

[0013] The right ends of the two height detection card plates are installed with limit plates.

[0014] A spring is installed between the limiting plate and the clamping plate base.

[0015] The outer diameter of the servo housing locating pin matches the inner diameter of the servo housing locating hole of the steering column.

[0016] Compared with the prior art, the utility model designs a detection tool for the height of the steering column adjustment handle, which can efficiently and conveniently detect the height of the adjustment handle after it is closed, saving measurement time, reducing the risk of pinching hands due to insufficient height of the adjustment handle, improving product quality, and avoiding the risk of production stoppage due to insufficient space for the adjustment handle.

The spacing between the column bracket positioning seats 41 of the two column bracket positioning mechanisms 4 matches the bracket length of the steering column 10; the outer diameter of the servo housing positioning pin 3 matches the inner diameter of the servo housing positioning hole of the steering column 10, so as to facilitate the installation and positioning of the steering column 10.
