[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model provides a chuck for machining automobile wheel hubs, which has the following advantages:

[0022] 1. The wheel hub contact chuck of this utility model can effectively sense whether the contact is complete through the contact sensing mechanism. When the contact is complete, the internal circuit of the contact sensing mechanism is opened, which can supply power to the warning light at the top of the wheel hub contact chuck, so that the warning light is lit. When the contact is incomplete, the warning light is not lit. Thus, the brightness of the warning light can effectively identify whether the contact is complete, which makes it more convenient to use.

[0032] Example 1

[0033] This embodiment provides a technical solution: a chuck for machining automobile wheel hubs, such as... Figures 1-5As shown, it includes a chuck mounting plate 1, a hub contact chuck, a lifting clamping mechanism, a warning light 4, and a contact sensing mechanism.

[0034] The inner side of the chuck mounting plate 1 is provided with a chuck groove 2, which allows for limited movement and clamping via the direction of the chuck groove 2. The wheel hub contact chuck is installed and fixed in the chuck groove 2 on the inner side of the chuck mounting plate 1. The wheel hub contact chuck can be positioned and moved within the chuck groove 2 on the inner side of the chuck mounting plate 1 by an external telescopic cylinder. A lifting clamping mechanism is installed and fixed at the upper end of the wheel hub contact chuck. After the wheel hub contact chuck contacts the outer side of the car wheel hub, the lifting clamping mechanism can press it down to effectively strengthen the fixation. The contact sensing mechanism is installed and fixed. On the inner side of the wheel hub contact chuck, the contact sensing mechanism can effectively sense whether the contact is complete when the contact is complete. When the contact is complete, the internal circuit of the contact sensing mechanism is opened. The warning light 4 is installed and fixed on the upper end of the wheel hub contact chuck. When the internal circuit of the contact sensing mechanism is open, it can supply power to the warning light 4 at the upper end of the wheel hub contact chuck, so that the warning light 4 lights up. When the contact is incomplete, the warning light 4 does not light up. Thus, the brightness of the warning light 4 can effectively identify whether the contact is complete, which makes it more convenient to use.

[0035] The hub contact chuck includes a contact chuck mechanism. A work plate sliding block 7 is installed at the lower end of the contact chuck mechanism. A movable groove 72 is provided on the inner side of the work plate sliding block 7. Rolling balls 71 are rotatably installed on the inner sides of both ends of the work plate sliding block 7. The work plate sliding block 7 is sleeved on the chuck mounting work plate 1 through the movable groove 72, and the rolling balls 71 are in rolling contact with the chuck mounting work plate 1.

[0036] The abutting block mechanism includes a chuck block housing 3, a screw mounting plate 31 fixed to the lower end of the chuck block housing 3, and a power supply battery 32 installed inside the chuck block housing 3 so as to provide power. The power supply battery 32 is electrically connected to the abutting sensing mechanism inside the chuck block housing 3, and the power supply battery 32 can provide power to the abutting sensing mechanism inside the chuck block housing 3.

[0037] The screw mounting plate 31 is connected to the upper end of the work plate sliding block 7 by screws, so that it can be installed and connected accordingly.

[0038] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the contact sensing mechanism includes a contact end block 6. The contact end block 6 is installed and connected to the clamp block housing 3 through the assembly plugs 63 at the four corners of the rear end, so that it can be installed and connected accordingly. The plug-in installation method makes the installation more convenient. A touch switch 61 is installed on the inner side of the contact end block 6. When the touch switch 61 contacts the external hub, the internal circuit of the touch switch 61 is opened. The touch switch 61 is electrically connected to the warning light 4 through the rear power connection line 62. When the internal circuit of the touch switch 61 is opened, the current is delivered to the warning light 4 through the power connection line 62. Thus, the personnel can effectively identify whether the contact is in place by the brightness of the warning light 4, which makes it more convenient to use.

[0039] In use, the wheel hub contact chuck can be positioned and moved in the chuck groove 2 inside the chuck mounting plate 1 via an external telescopic cylinder. The wheel hub contact chuck can effectively contact and clamp the wheel hub in four directions. After the wheel hub contact chuck contacts the outside of the car wheel hub, it can be pressed down by the lifting clamping mechanism to effectively strengthen the fixation. The contact sensing mechanism is installed and fixed on the inside of the wheel hub contact chuck. When the wheel hub contact chuck is in contact, the contact sensing mechanism can effectively sense whether the contact is complete. When the contact is complete, the internal circuit of the contact sensing mechanism is opened. The warning light 4 is installed and fixed on the upper end of the wheel hub contact chuck. When the internal circuit of the contact sensing mechanism is open, it can supply power to the warning light 4 at the upper end of the wheel hub contact chuck, so that the warning light 4 is lit. When the contact is incomplete, the warning light 4 is not lit. Thus, the brightness of the warning light 4 can effectively identify whether the contact is complete, which makes it more convenient to use.

[0040] Example 2

[0041] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, to further better realize this utility model, the following configuration is specifically adopted: the lifting clamping mechanism includes an electric telescopic cylinder 8, and a cylinder mounting plate 81 is installed on the periphery of the electric telescopic cylinder 8. The electric telescopic cylinder 8 is installed and connected to the abutting clamping block mechanism through the cylinder mounting plate 81, so that the electric telescopic cylinder 8 can be stably installed and placed. A movable pressure plate 82 is fixedly connected to the telescopic rod end of the electric telescopic cylinder 8. When the telescopic rod of the electric telescopic cylinder 8 extends and retracts, it can drive the movable pressure plate 82 to rise and fall. An abutting pressure plate 5 is fixedly connected to the lower end of the movable pressure plate 82. The movable pressure plate 82 can drive the abutting pressure plate 5 to rise and fall. Thus, the abutting pressure plate 5 can effectively abut against or release the wheel hub, thereby playing a secondary abutting clamping role.

[0042] Two electric telescopic cylinders 8 are installed, and the electric telescopic cylinders 8 are symmetrically installed on the movable pressure plate 82, so that the movable pressure plate 82 is more stable when it is raised and lowered by the two electric telescopic cylinders 8.
