Description

Technical Field

[0001] The utility model belongs to the technical field of steering column assembly equipment, in particular to a tooling device for a steering column. Background Art

[0002] At present, front forks are more common in motorcycles, electric vehicles or bicycles, and fixed shock absorbers are usually set at both ends of the front fork to form a steering column, which is mainly used to produce buffering and steering effects when contacting ground obstacles.

[0003] like Figure 1 As shown, during the installation of the steering column, the ends of the two shock absorbers 8 are fastened to the two ends of the front fork 9 by bolts. Usually, notches 90 for fastening are formed at both ends of the front fork 9, and a locking block 91 fastened to the other side by bolts is provided on one side of the notch 90. By tightening the bolts, the notch 90 is closed so that the ends of the shock absorbers 8 are fastened and installed, completing the assembly of the steering column.

[0004] However, since the steering column is an irregular structure as a whole, the tooling structure usually used to assemble the steering column assembly is relatively simple, which is mainly convenient for manual installation. However, for the steering column assembly in the automated production process, the tooling not only needs to consider the stability of the bolts during assembly, but also needs to perform shock-absorbing installation strength verification to improve the pass rate. Summary of the invention

[0005] The utility model aims to provide a tooling device for a steering column, which effectively fixes and clamps a steering column, thereby facilitating the installation and verification of shock absorbers.

[0006] The purpose of the utility model is achieved in this way:

[0007] A tooling device for a steering column comprises a mold base plate fixed on a base, two rotating seats arranged opposite to each other are fixed on the upper end of the mold base plate, a rotating body is rotatably connected between the two rotating seats, a mounting hole is opened in the middle of the rotating body, a "U"-shaped support frame is provided on one side of the rotating body, a rubber pad perpendicular to the surface of the support frame is fixed on one side of the support frame; a booster cylinder fixed above the frame group is provided on one side of the base, an upper mold connecting seat is fixed on the end of the piston rod of the booster cylinder, shock-absorbing plates are fixed on both sides of the upper mold connecting seat, and one side of the shock-absorbing plate is abutted against one end of the shock absorber in the steering column.

[0008] The utility model is further configured that a connecting rod is fixed to the other side of the upper die connecting seat away from the piston rod of the booster cylinder, and an upper pressing sleeve for abutting against the front side of the front fork is arranged at the other end of the connecting rod.

[0009] The utility model is further configured that a mold ring is fixed on the front side of the installation hole, and an arc-shaped guide opening is opened on the front side of the mold ring.

[0010] The utility model is further configured that a slide rail is fixed on the rear side of the frame group, a sliding block is slidably arranged on the slide rail, and the top of the sliding block is fixed to the bottom of the upper mold connecting seat.

[0011] The utility model is further configured that the support frame is provided with left-right symmetrical assembly holes and assembly grooves, and the middle part of the rubber pad is fixed in the assembly hole or the assembly groove by bolts.

[0012] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects:

[0013] The tooling provided by the utility model can support the steering column assembly of the special-shaped structure through the rotating seat and the rubber pad, and utilizes the booster cylinder upper die connecting seat provided at one end to squeeze the end of the shock absorber, which can not only adjust the corresponding position so that the shock absorber and the two ends of the front fork are at the same horizontal height, but also can play a role in verifying the installed shock absorber.

[0030] During the implementation, the steering column in the middle of the front fork 9 is inserted into the mounting hole 30, and before insertion, the rotating body 3 can be rotated between the two rotating seats 20 to make it in an inclined state, which facilitates the insertion of the steering column in the steering column. After being inserted into the mounting hole 30, the lower end surface of the front fork 9 abuts against the upper end of the rubber pad 32, so that the surface of the workpiece is not easily scratched;

[0031] After the front fork is placed, the booster cylinder 5 drives the piston rod to push the upper mold connecting seat 6, driving the shock-absorbing plate 60 to push the end of the shock absorber 8, thereby synchronously installing the shock absorber in the notch 90.

The mold ring 35 facilitates the abutment of the rear side of the front fork, and the arc-shaped guide opening is provided to facilitate the insertion of the steering column.

[0036] In the above structure, the rear end of the mold ring can be inserted into the mounting hole, and a screw is inserted above the mounting hole 30 to fix the mold ring; and the hole opened in the middle of the mold ring is adapted to the diameter of the steering column, and different mold rings are installed for steering columns of different specifications, so that the device has a wider range of applications.
