Description

Technical Field

[0001] The utility model relates to the motorcycle wheel hub manufacturing industry, in particular to a motorcycle wheel hub laser engraving technology, and specifically to a motorcycle wheel hub laser engraving jig. Background Art

[0002] In the motorcycle wheel production line, the last process before packaging is to laser engrave the relevant model, parameters and brand logo on the edge of the wheel. Taking the BMW-KA1-19x3.0 series wheel as an example, the laser engraving position required for this model is on the edge arc surface, and the existing laser engraving machines are all vertical lasers from top to bottom, so it is difficult to meet the quality requirements of the laser pattern. In the product development stage, there was a set of jigs that could only manually rotate and adjust the pattern. This set of jigs was inefficient and lacked precision; the product has now entered the mass production stage, and the existing jigs can no longer meet the requirements of production efficiency and precision. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a motorcycle wheel hub laser engraving jig, which can tilt the motorcycle wheel hub to facilitate laser engraving, and at the same time control the rotation angle of the wheel hub by driving a motor, with a high degree of automation, which not only meets the laser engraving precision requirements, but also greatly improves work efficiency.

[0004] The utility model is realized by the following technical solutions:

[0005] A motorcycle wheel hub laser engraving jig comprises a bottom plate, a surface of which is slidably connected with a bracket bottom plate, and a bracket base is arranged on the bracket bottom plate;

[0006] The top of the bracket base is provided with an inclined motor connecting plate, a driving motor is installed on the motor connecting plate, a supporting shaft is installed at the output end of the driving motor, and a cavity is provided on the top surface of the supporting shaft for embedding the outer side of the middle hub of the wheel hub;

[0007] A fixing rod capable of passing through the hub shaft hole is connected to the center position of the cavity, and a detachable pressing head cover is connected to the outer end of the fixing rod.

[0008] Furthermore, the cavity is a stepped cavity that can match the outer contour of the center hub of the wheel hub.

[0009] Furthermore, a slotted hole is provided on the clamping head cover, and the slotted hole is threadedly connected to the top end of the fixing rod through a T-shaped bolt.

[0010] Furthermore, the outer circumference of the clamping head cover is provided with an annular groove which can clamp the outer edge of the middle hub of the wheel hub.

[0011] Furthermore, a slide rail is arranged on the bottom plate, and a slider slidably connected to the slide rail is arranged at the bottom of the bracket bottom plate.

[0012] Furthermore, an electric cylinder is provided on the base, and a movable end of the electric cylinder is connected to the end of the bracket bottom plate through a connecting block.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are as follows:

[0014] 1. After passing the motorcycle wheel hub through the fixing rod, assemble it on the cavity, and fix the wheel hub by pressing the head cover. After the motorcycle wheel hub is fixed, it is placed at an angle to facilitate laser engraving. At the same time, the rotation angle of the wheel hub is accurately controlled by the driving motor. The high degree of automation not only meets the precision requirements of laser engraving, but also greatly improves the work efficiency.

[0015] 2. The slotted hole is threadedly connected to the top of the fixing rod through a T-shaped bolt. When the clamping head cover needs to be removed to take out the wheel hub, the T-shaped bolt is loosened and aligned with the slotted hole, so that it is convenient to remove the clamping head cover and further remove the wheel hub, saving disassembly and installation time;

[0016] 3. When the T-bolt is tightened, the annular groove of the compression head cover can tightly clamp the outer edge of the middle hub of the wheel hub, thereby ensuring that the wheel hub can be firmly fixed on the support shaft;

[0017] 4. The electric cylinder drives the bracket bottom plate to move, and the driving motor controls the rotation angle, making the entire laser engraving process automated, greatly improving work efficiency;

[0018] The angle setting of the motor rotation replaces the original positioning function of the positioning pin, thus avoiding the problem of poor accuracy caused by the wear of the positioning pin. BRIEF DESCRIPTION OF THE DRAWINGS
