Referring to fig. 1 to 18, according to an embodiment of the present invention, there is provided a wheel clamping apparatus including a base assembly 10, a support bracket 20, and a driving assembly 30.

Wherein the base assembly 10 comprises a base 11; the supporting frame 20 is installed on the base assembly 10, and an installation space for vertically installing the wheel 80 is provided on the supporting frame 20; the driving assembly 30 is mounted on the base 11 to drive the wheel 80 to rotate in the mounting space.

According to the above structure, since the mounting space for vertically mounting the wheel 80 is provided on the support frame 20 of the wheel clamping device in this embodiment, when the mechanical property of the wheel 80 is actually tested, the test instrument 90 can be quickly mounted when the test instrument 90 tests the test positions of the tread, the rim, the side surfaces and the like of different positions of the wheel 80 in the test process, and meanwhile, the wheel 80 can be driven to rotate by the driving assembly 30, so that the test position can be changed, the working time is greatly saved, and the labor intensity of the tester is reduced.

As shown in fig. 1 to 4, 10 and 11, the base assembly 10 in the present embodiment further includes a base plate 12 and support legs 13, wherein the base 11 is mounted on the base plate 12 by a first connector 40; support legs 13 are attached to the base plate 12.

Referring to fig. 1, the present invention is provided to solve the problem that the test instrument 90 is difficult to be fixed at the test positions of the rim and the tread of the wheel 80, the side surface of the wheel 80, and the like. Because the wheel 80 has a relatively large volume and a relatively heavy weight, repeated clamping is time consuming. The stand 20 of the present invention includes a first side frame 21, a second side frame 22, and a top bracket 23.

Wherein, the first side frame 21 is fixed on the bottom plate 12 through the second connecting piece 50 and is positioned at the first side of the base 11; the second side frame 22 is fixed on the base plate 12 by a third connecting member 60 and is positioned on a second side of the base 11 opposite to the first side; the top bracket 23 is fixed to the top of the first and second side frames 21 and 22 by a fourth connecting member 70.

Therefore, the testing time is shortened, the working efficiency is improved, and the working intensity is greatly reduced.

In actual installation, the present invention uses screws to connect the threaded holes on the two sides of the base 11 and the threaded holes on the bottom plate 12 through the first connecting member 40, so as to position the wheels 80.

Referring to fig. 5 to 8, the driving assembly 30 in the present embodiment includes a rotating shaft 31 and a bearing (not shown), and the rotating shaft 31 is mounted on the base 11 through the bearing. In actual installation, the rotating shaft 31 and the corresponding bearing are installed inside the base 11 in this embodiment, as shown in fig. 6, the right end is a portion of the rotating shaft 31, and the rotating shaft 31 rotates to drive the wheel 80 to rotate, so as to adjust the test position without detaching the wheel 80. Meanwhile, the base 11 is provided with at least one lightening hole 112, and preferably, the lightening hole 112 in the embodiment is 5 round holes, so that the strength of the structure is ensured, and the effect of lightening the weight is achieved.

Referring to fig. 1 and 12, the first and second side frames 21 and 22 of the present invention have holes formed at the bottom thereof, and are coupled to the base plate 12 through the holes at the lowermost portions thereof by screws and the second and

third coupling members

50 and 60, respectively, in the front and rear directions of the wheel 80. The first side frame 21 and the second side frame 22 are formed with a plurality of first through holes 24, and the test instruments 90 can be installed at different positions according to different test positions, respectively, while the first through holes 24, to which the test instruments 90 are not installed, can be used to screw in the long bolts 26, in such a manner that the wheels 80 are fixed by the long bolts 26 at both sides. While the first and second side frames 21 and 22 are also important parts for supporting the top support 20.

Preferably, the first side frame 21, the second side frame 22 and the top bracket 23 in this embodiment are rectangular frames. Of course, in other embodiments of the present invention, the first side frame 21, the second side frame 22 and the top frame 23 may be configured as a square frame structure, and any other modifications within the spirit of the present invention are within the scope of the present invention.

In FIG. 18, the holes are distributed in 4 holes on the left and right. The middle one is used for connecting the test instrument 90, and the other four are used for connecting the top bracket 23 with the first side frame 21 and the second side frame 22. The top support 23 plays a role in reinforcing the whole structure, and the mechanical properties of the tread and the wheel rim can be measured after the test instrument 90 is installed, so that the structure is simple, and the stability is high.

In a preferred embodiment of the present invention, the base 11 can be a magnetic base, and a larger base 11 capable of being switched on and off can be made to fix the wheel 80. However, the base 11 is made of a magnetic material as a whole, which is expensive and poor in adjustability and is not easy to handle.
