Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts processing, and in particular relates to a nut pre-tightening platform for installing a click plate on a steering wheel. Background Art

[0002] Cars are one of the indispensable means of transportation in modern society, and the steering wheel is one of the core control devices in car driving. In modern car design, the steering wheel is not only a tool for steering, but also integrates various control buttons to provide additional functions and convenience. Among them, the horn button, also known as the horn button or horn switch, is one of the important safety devices and is placed in the steering wheel housing so that the driver can issue an alarm signal when needed.

[0003] At present, the click plate is installed in the housing by means of a bolt assembly, which needs to go through a processing procedure of pre-tightening before tightening. During the pre-tightening process, the traditional method is to manually install the bolt in the threaded hole first, and then tighten the nut from the back. The installation of multiple sets of bolt assemblies requires flipping the steering wheel back and forth, which is time-consuming and labor-intensive to operate, and has low processing efficiency.

[0004] Therefore, we propose a nut pre-tightening platform for installing a click plate on a steering wheel to solve the above technical problems. Utility Model Content

[0005] In order to solve the technical problem in the above-mentioned prior art that the pre-tightening process of the steering wheel mounting click plate requires flipping the steering wheel back and forth, which is time-consuming and labor-intensive to operate and has low processing efficiency, the utility model proposes a nut pre-tightening platform for the steering wheel mounting click plate.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A nut pre-tightening platform for installing a click plate on a steering wheel comprises a base plate and a positioning device installed on the base plate, wherein the positioning device comprises a plurality of nut positioning columns corresponding to the screw hole positions of the click plate, the nut positioning columns are all arranged perpendicular to the base plate, and the top surfaces of the nut positioning columns are all provided with nut placement and fixing holes matching the shape of the nut.

[0008] By adopting the above technical scheme, when the utility model is in use, a nut is placed in the nut placing and fixing hole of each nut positioning column, and the nut will be restricted from rotating in the nut placing and fixing hole. Then the click plate is placed in the steering wheel, and the screw hole position of the click plate is aligned with the screw hole position of the steering wheel. The steering wheel is then placed on the pre-tightening table, and the screw hole position is aligned with the nut positioning column. Finally, a screw is used to pass through the screw hole position and screwed into the nut until all the screws are screwed into the corresponding nuts, thereby completing the pre-tightening process. The whole process does not require screwing the nut from the back, nor does it require flipping the steering wheel back and forth, which is convenient for production line workers to use, effectively reduces the workload of production line workers, improves processing efficiency, and is beneficial to production.

[0009] In a further technical solution, the nut positioning column includes a sleeve and a push rod, the sleeve is connected to the base plate, the push rod is slidably arranged in the sleeve and the push rod is elastically connected to the sleeve, and the nut placement fixing hole is opened on the top surface of the push rod.

[0010] By adopting the above technical solution, the nut positioning column is designed through the sleeve and the push rod, the push rod is slidably set in the sleeve and elastically connected in the sleeve, and a return spring is often used, which can perform a certain degree of downward pressure and rebound. When placing the steering wheel, it has a certain buffering capacity, thereby reducing the probability of damage to the steering wheel and the button plate due to operational errors.

[0011] In a further technical solution, the sleeve is provided with a plurality of Z-direction support blocks on the outer side of the push rod.

[0012] By adopting the above technical solution, the steering wheel is effectively supported by the Z-axis support block to prevent the steering wheel from falling down, thereby facilitating the pre-tightening process.

[0013] In a further technical solution, the base plate is further provided with a center positioning rod for extending into the center hole of the steering wheel.

[0014] By adopting the above technical solution, the center positioning rod is extended into the center hole of the steering wheel, which can assist in positioning the steering wheel, and is conducive to aligning the screw hole positions of the steering wheel and the click plate with the nut positioning column, which is convenient for use.

[0015] In a further technical solution, the base plate is provided with auxiliary limiting rods on both sides of the central positioning rod.

[0016] By adopting the above technical solution, the auxiliary limit rods on both sides of the central positioning rod can not only assist the steering wheel in positioning, but also cooperate with the holes on the steering wheel, thereby effectively limiting the rotation of the steering wheel and facilitating use.

[0017] In a further technical solution, an operating table is also included, and the base plate is detachably connected to the operating table.

[0018] By adopting the above technical solution, the base plate is installed on the operating table to facilitate movement, and different layouts are designed by changing the number and position of the nut positioning columns. The base plate can be detachably installed on the operating table, so that the preload table can be used in the preload process of steering wheels of different specifications, which is conducive to reducing costs.

[0019] In a further technical solution, holes are provided on the base plate and the operating table and the base plate and the operating table are connected by bolts.

[0020] By adopting the above technical solution, the base plate and the operating table are connected by bolts, which is convenient for disassembly and installation and is conducive to use.

[0021] In a further technical solution, handles are provided on both sides of the operating table.

[0022] By adopting the above technical solution, the operating table can be conveniently carried by the handles on both sides, which is convenient for use.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0024] 1. The utility model does not need to screw the nut from the back or flip the steering wheel back and forth during the entire pre-tightening process, which is convenient for production line workers to use, effectively reduces the work intensity of production line workers, improves processing efficiency, and is beneficial to production.

[0025] 2. The utility model can assist in positioning the steering wheel through the center positioning rod and the auxiliary limiting rod, facilitate the alignment of the screw holes of the steering wheel and the click plate with the nut positioning column, and can also cooperate with the holes on the steering wheel, thereby effectively limiting the rotation of the steering wheel and facilitating use.
