[0002] The wheel hub is a cylindrical metal component with the inner contour of the tire supporting the tire and the center mounted on the shaft. It is also called a rim, steel ring, wheel, or tire bell. In the past, most car wheel hub bearings were used in pairs of single-row tapered roller or ball bearings. With the development of technology, car hub units have been widely used in cars. The scope and usage of wheel hub bearing units are increasing. Most vehicle wheels will choose to laser engrave a unique logo to improve recognition.

[0003] However, due to the inconsistency of the outer diameters of the hubs, conventional laser engraving machines generally do not have a good positioning structure, and when installing multiple hubs, the positions need to be adjusted multiple times, resulting in low processing efficiency.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, this embodiment provides a laser engraving device, including a laser engraving chamber 1, a wheel hub clamping mechanism is arranged inside the laser engraving chamber 1, the wheel hub clamping mechanism includes: a first clamping mechanism 6, a second clamping mechanism 7, the first clamping mechanism 6 and the second clamping mechanism 7 have the same structure, the outer sides of the first clamping mechanism 6 and the second clamping mechanism 7 are located inside the laser engraving chamber 1 and a guide groove 5 is opened, the first clamping mechanism 6 includes: a crank 601, a reciprocating screw rod 602, and a screw rod movable cylinder 606, the screw rod movable cylinder 606 is engaged and movably connected with the reciprocating screw rod 602, a limit slider 604 is installed above the screw rod movable cylinder 606, the limit slider 604 is slidably connected with the guide groove 5, a wheel hub clamping block 603 is installed on the upper end of the limit slider 604, and the wheel hub clamping block 603 is fixedly connected with the limit slider 604, a centering mechanism 8 is arranged inside the laser engraving chamber 1, and a rotating bearing 605 is installed in the middle of the crank 601.

[0024] like Figure 2-5 As shown, in this embodiment, the internal array of the centering mechanism 8 is provided with a conical cylinder 801, and the conical cylinder 801 is set with a variable diameter. The centering mechanism 8 is a conical structure and can be used to center the wheel hubs with various different center apertures. A spring 802 is connected between the lower end of the centering mechanism 8 and the laser engraving chamber 1, and the centering mechanism 8 is fixedly connected to the laser engraving chamber 1 through the spring 802. A handle 803 is installed at the upper end of the centering mechanism 8, and a limited stopper 804 is arranged between two adjacent conical cylinders 801. A movable guide rail 2 is installed at the upper end of the laser engraving chamber 1, and an engraving frame 3 is installed above the movable guide rail 2. The engraving frame 3 is slidably connected to the movable guide rail 2, and a laser engraving head 4 is installed in front of the engraving frame 3, and the laser engraving head 4 is slidably connected to the engraving frame 3.

[0025] The working principle of the utility model is as follows: when in use, because the center holes of wheel hubs of the same size have the same size, after the center hole of the wheel hub to be engraved is positioned above the centering mechanism 8 as a whole, the handle 803 above the centering mechanism 8 is pulled upward as a whole, so that the conical cylinders 801 arranged in an array inside the centering mechanism 8 are pulled upward as a whole, and the limit stopper 804 between two adjacent conical cylinders 801 can be used for limiting. When the multiple conical cylinders 801 are in the maximum pulling position, the spring 802 below the centering mechanism 8 can be pulled and deformed, and then the centering mechanism 8 passes through the center hole of the wheel hub as a whole, and can be used for adjustment. The installation position of the hub is determined by synchronously controlling the first clamping mechanism 6 and the second clamping mechanism 7 to move. After the torque is applied to the crank 601 as a whole, the reciprocating screw 602 is controlled to rotate using the rotating bearing 605. The rotating reciprocating screw 602 controls the meshing movement of the screw movable cylinder 606. The limiting slider 604 above the screw movable cylinder 606 moves inside the guide groove 5. Then, the multiple hub clamps 603 arranged on the first clamping mechanism 6 and the second clamping mechanism 7 will move synchronously toward the center position as a whole to support and position the outer side of the hub. Then, the positioning purpose can be achieved after the subsequent placement of the wheel roller.
