[0033] Related background technology: On the instrument assembly line, the steering column 100 is connected to the instrument by bolts, and the steering column 100 can rotate along its own axis. On the interior line, the steering intermediate shaft 200 is connected to the front panel of the vehicle. On the chassis line, the connection between the steering intermediate shaft 200 and the steering column 100 is assembled with bolts, and the bolts need to be tightened by power tools to realize the assembly connection between the steering intermediate shaft 200 and the steering column 100. A spline structure 101 is provided at the end of the steering column 100 away from the steering intermediate shaft 200. The spline structure 101 is assembled and connected to the steering wheel. When the steering wheel is turned, the steering column 100 can be driven to rotate, and then the steering intermediate shaft 200 is driven to rotate together, thereby driving the steering gear to rotate to realize steering control of the wheels. However, when tightening the bolt connection between the steering intermediate shaft 200 and the steering column 100 on the chassis line, since the bolt connection is facing the co-pilot, when the person in the main driver's seat operates the power tool to tighten the bolt, on the one hand, the human-machine position is uncomfortable, and on the other hand, the power tool is likely to interfere with the vehicle body floor / body side beam / brake pedal. Based on this, the present application provides an auxiliary tool that can rotate the steering column 100 and the steering intermediate shaft 200 to adjust the direction of the bolt at the connection between the two to facilitate personnel operation.

[0034] Below, according to Figures 1 to 7 , describing an embodiment of the present utility model.

[0035] like Figures 1 to 4 As shown, according to an embodiment of the present invention, on the one hand, an auxiliary tooling is disclosed for assisting the connection and assembly between the steering column 100 and the steering intermediate shaft 200 of a vehicle. The steering column 100 has a spline structure 101 at one end away from the steering intermediate shaft 200. The auxiliary tooling includes a handle 1 and a mating portion 2. The mating portion 2 is fixedly connected to the handle 1. The mating portion 2 has a mating hole 21. The inner wall of the mating hole 21 is provided with a rack structure 211 for engaging with the spline structure 101. When the handle 1 is driven, the mating portion 2 is driven to rotate, thereby driving the steering column 100 and the steering intermediate shaft 200 to rotate together to a preset position.

[0036] The auxiliary tooling of the present application is provided with a rack structure 211 on the inner wall of the mating hole 21 of the mating part 2. When in use, the auxiliary tooling is sleeved on the end of the steering column 100 away from the steering intermediate shaft 200 through the mating hole 21, and the rack structure 211 on the inner wall of the mating hole 21 is engaged with the spline structure 101 of the steering column 100. The operating handle 1 is used to drive the mating part 2 to rotate, thereby driving the steering column 100 and the steering intermediate shaft 200 to rotate together to a preset position, thereby realizing the position and direction adjustment of the bolted connection between the steering column 100 and the steering intermediate shaft 200, avoiding interference between the power tool and the vehicle body floor / body side beam / brake pedal when tightening the bolted connection, and also facilitating personnel to work in the best posture, improving personnel working comfort and assembly efficiency.

[0037] like Figure 6 and Figure 7 As shown, it can be understood that the initial position of the bolt connection position 300 between the steering column 100 and the steering intermediate shaft 200 is obliquely facing the co-driver of the vehicle, and the preset position in this application is the position facing the main driver, that is, after the auxiliary tooling of this application is rotated, the bolt connection position 300 between the steering column 100 and the steering intermediate shaft 200 is facing the main driver. At this time, the person in the main driver can face the bolt connection position 300 to tighten the bolts of the bolt connection position 300, which is more convenient and more ergonomic.

[0038] It should be noted that the spline structure 101 is the structure of the steering column 100 itself, and the spline structure 101 is used to connect to the steering wheel. However, the present application cleverly sets a rack structure 211 on the inner wall of the mating hole 21 to engage with the spline structure 101, and there is no need to set an additional mating structure on the steering column 100.

[0039] In some embodiments, the rack structure 211 is partially disposed along the circumference of the inner wall of the fitting hole 21 .

[0040] With the above arrangement, part of the rack structure 211 can be engaged with the spline structure 101 on the steering column 100 . In this case, the rack structure 211 does not need to be arranged along the inner wall of the matching hole 21 circumferentially, which can simplify the processing technology and reduce the processing difficulty.

[0041] Of course, in other embodiments, the rack structure 211 may also be provided along the circumference of the inner wall of the fitting hole 21 .

[0042] The meshing of the rack structure 211 and the spline structure 101 ensures the reliability of the fit between the fitting portion 2 and the steering column 100 .

[0043] In some embodiments, the handle 1 includes a fixed gripping portion 11 and a first connecting portion 12 , the gripping portion 11 and the first connecting portion 12 are arranged at an angle, the first connecting portion 12 and the mating portion 2 are fixedly connected, and the center line of the mating hole 21 is parallel to the first connecting portion 12 .

[0044] By setting the handle 1 into a fixed gripping portion 11 and a first connecting portion 12, it is convenient for people to operate the handle 1 through the gripping portion 11. The first connecting portion 12 is used to be fixedly connected to the matching portion 2, and the gripping portion 11 and the first connecting portion 12 are set at an angle, which can make the gripping portion 11 form a torque, making it convenient for people to operate with less effort, and also convenient to observe the matching status of the matching portion 2 and the steering column 100.

[0045] Preferably, the holding portion 11 and the first connecting portion 12 are arranged at ninety degrees. During operation, the holding portion 11 as a whole forms a torque and performs a rotation operation with the matching portion 2 as the center, which maximizes the operation effort saving effect. However, it is not limited to this. For example, in other embodiments, the holding portion 11 and the first connecting portion 12 can also be thirty degrees, forty-five degrees, etc.

[0046] In some embodiments, a flexible body is provided on the periphery of the grip portion 11 .

[0047] The flexible body can facilitate people to grasp the gripping portion 11 and improve the comfort of operation.

[0048] Specifically, the flexible body may be made of materials such as sponge, elastic plastic or rubber, and this embodiment does not impose any specific limitation.

[0049] For example, the gripping portion 11 may be configured as a long strip, the flexible body may be wrapped around the outer periphery of the gripping portion 11 , the first connecting portion 12 and the gripping portion 11 may be integrally formed, and the first connecting portion 12 and the gripping portion 11 may be L-shaped as a whole.

[0050] The matching portion 2 may be circular, elliptical or geometric in shape. In this embodiment, the matching portion 2 is described as a circular shape.

[0051] The mating hole 21 is arranged at the center of the mating portion 2. The aperture of the mating hole 21 matches the diameter of the steering column 100 so that the mating portion 2 can be matched and sleeved on the steering column 100, and the rack structure 211 and the spline structure 101 are interference fit. When the mating portion 2 rotates under the drive of the handle 1, the meshing rack structure 211 and the spline structure 101 can transmit torque to the steering column 100 to drive the steering column 100 to rotate together.

[0052] like Figure 2 As shown, in some embodiments, the length L from the center line of the fitting hole 21 to the end of the gripping portion 11 away from the first connecting portion 12 is greater than 220 mm.

[0053] By setting the length L from the center line of the fitting hole 21 to the end of the gripping portion 11 away from the first connecting portion 12 to be greater than 220 mm, the torque of the auxiliary tooling is made greater than 220 mm, thereby achieving the effect of labor-saving operation as much as possible.

[0054] It should be noted that the radius of the steering wheel of a vehicle is generally 220 mm to the right, but when the vehicle is steered, the steering column 100 can be operated with both hands through the steering wheel, and the auxiliary tooling of the present application is operated with one hand, so the length L from the center line of the mating hole 21 to the end of the gripping part 11 away from the first connecting part 12 is set to be greater than the radius of the steering wheel (220 mm), so that the auxiliary tooling of the present application is more labor-saving to operate than the steering wheel.

[0055] For example, the value of L may be 230 mm, 240 mm, or 250 mm, etc., and this embodiment does not impose any specific limitation.

[0056] In some embodiments, the mating portion 2 and the first connecting portion 12 are detachably connected.

[0057] By setting the fitting part 2 and the first connecting part 12 as a detachable connection, when the fitting part 2 is damaged and needs to be replaced, the fitting part 2 can be replaced by disassembling the fitting part 2 and the first connecting part 12 while retaining part of the structure of the handle 1, thereby reducing replacement costs.

[0058] like Figure 5 As shown, in some embodiments, the auxiliary tooling further includes a second connecting portion 3 , the second connecting portion 3 and the matching portion 2 are integrally connected, and the second connecting portion 3 and the first connecting portion 12 are detachably connected.

[0059] On the one hand, the second connecting part 3 can enhance the structural strength of the matching part 2. On the other hand, the setting of the second connecting part 3 also facilitates the connection between the matching part 2 and the first connecting part 12, avoiding the need for punching or grooving when the matching part 2 and the first connecting part 12 are directly connected, which may cause a decrease in the structural strength of the matching part 2.

[0060] Specifically, one end of the second connection portion 3 is integrally formed along the outer arc-shaped surface of the matching portion 2 , and the other end of the second connection portion 3 is used for detachable connection with the first connection portion 12 .

[0061] In some embodiments, the first connecting portion 12 and the second connecting portion 3 are both provided with corresponding connecting holes, and the auxiliary tooling further includes a fastener 4, which is detachably connected to the connecting hole.

[0062] By setting corresponding connecting holes on the first connecting part 12 and the second connecting part 3, and using fasteners 4 to be detachably connected to the connecting holes, detachable fixation between the first connecting part 12 and the second connecting part 3 is achieved. When disassembling, the fasteners 4 can be pulled out from the connecting holes to achieve disassembly of the mating part 2.

[0063] For example, the connection hole can be a plain hole, and the fastener 4 is a fastening pin that is snap-fitted into the connection hole to achieve fixation. Of course, the connection hole can also be a threaded hole, and the fastener 4 is a bolt / screw that is threadedly tightened into the threaded hole to achieve a threaded connection between the first connection portion 12 and the second connection portion 3.

[0064] In other embodiments, one of the first connecting portion 12 and the second connecting portion 3 is provided with a slot, and the other one is provided with a pin, and the pin is plugged into the slot.

[0065] A slot is provided in one of the first connection part 12 and the second connection part 3 , and a pin is provided in the other one. The pin is plugged into the slot to achieve plug-in fixation between the first connection part 12 and the second connection part 3 .

[0066] A second aspect of the present application further provides a vehicle assembly production line, comprising the above-mentioned auxiliary tooling.

[0067] Since the vehicle assembly production line of the present application includes the auxiliary tooling of the present application, it has the same technical effect as the auxiliary tooling, and this embodiment will not be repeated.

[0068] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in this application should be included in the scope of protection defined in this application.
