Description

Technical Field

[0001] This utility model belongs to the technical field of children's vehicle manufacturing equipment, and specifically relates to a children's vehicle wheel mounting device. Background Technology

[0002] In the traditional process of assembling children's vehicles, wheel assembly requires manual completion of processes such as connecting the axle to the wheel, threading the axle, and hammering to fix it. This has many drawbacks: such as very low efficiency of manual operation, only one side can be pressed at a time, and the hammering force is difficult to control precisely, which can lead to damage to parts. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a children's vehicle wheel mounting device that effectively improves assembly efficiency.

[0004] This utility model provides a children's bicycle wheel mounting device, including a frame, a slide rail, a positioning fixture, and a vertical pressing mechanism. The frame is composed of a horizontal base plate and a vertical support plate. The slide rail is mounted on the horizontal base plate. The bottom of the positioning fixture is provided with a slider that slides with the slide rail. The positioning fixture is provided with an array of wheel positioning grooves for fixing the left / right wheel sets and matching the wheels. The positioning fixture is also provided with a body contour positioning protrusion for supporting the main body of the bicycle. The body contour positioning protrusion is adapted to the three-dimensional shape of the side of the bicycle. The vertical pressing mechanism is mounted on the vertical support plate and includes at least two sets of cylinders and a pressing block connected to the cylinder piston rod. The extension direction of the slide rail is perpendicular to the pressing path of the vertical pressing mechanism. A touch switch is provided on the horizontal base plate. When the positioning fixture slides to the pressing position, the rear side of the positioning fixture contacts the touch switch and triggers the cylinder to press down.

[0005] The touch switch is a mechanical limit switch, and its triggering direction is parallel to the sliding direction of the positioning fixture, so as to realize the automatic triggering of the pressing action and avoid human operation error.

[0006] The touch switch is installed at the same height as the rear side of the positioning fixture. When the operator pushes the positioning fixture along the slide rail to the pressing station, the rear side of the positioning fixture contacts the touch switch, generating an electrical signal that is transmitted to the controller. The controller then sends a start command to the cylinder of the vertical pressing mechanism, automatically triggering the pressing action.

[0007] As a further embodiment of this utility model, the vertical pressing mechanism includes two independently controlled cylinder groups, corresponding to the front axle and rear axle pressing stations respectively.

[0008] The slide rail is provided with a limiting block at its end. When the positioning fixture is pulled out from the press-fitting station, the limiting block contacts the stop surface at the end of the slide block, limiting the maximum displacement stroke of the fixture and preventing the positioning fixture from being pulled out excessively, which could lead to the risk of the slide block derailing.

[0009] The pressure block is equipped with an elastic buffer layer to prevent damage to the wheel surface.

[0010] The positioning fixture is equipped with a handle, which the operator holds to push the positioning fixture.

[0011] The working process of this utility model is as follows: First, place the front / rear left wheels into the wheel positioning grooves on the positioning fixture, place the vehicle body on the positioning protrusion of the positioning fixture, manually pre-insert the rotating shaft into the left wheel axle hole, then place the right wheel and pre-connect it with the other end of the rotating shaft, hold the handle and push the positioning fixture to the pressing station, the rear side of the positioning fixture contacts the touch switch, generating an electrical signal that is transmitted to the controller, the controller sends a start command to the cylinder of the vertical pressing mechanism, the cylinder drives the pressure block to apply pressure to the right wheel, thereby realizing the connection of the left wheel and the right wheel to the rotating shaft respectively.

[0012] The beneficial effects of this utility model are as follows: the sliding positioning fixture realizes the pre-positioning of the car body and the wheels, and the dual-station vertical pressing mechanism realizes the synchronous pressing of the front and rear axles, effectively improving the assembly efficiency.

The bottom of the positioning fixture 3 is provided with a slider 5 that slides and engages with the slide rail 2. The positioning fixture 3 is provided with an array of wheel positioning grooves 31 for fixing the left / right wheel sets and matching the wheels. The positioning fixture 3 is also provided with a body contour positioning protrusion 32 for supporting the main body of the vehicle body. The body contour positioning protrusion 32 is adapted to the three-dimensional shape of the side of the vehicle body. The vertical pressing mechanism 4 is mounted on the vertical support plate 12. The vertical pressing mechanism 4 includes at least two sets of cylinders 41 and a pressing block 42 connected to the piston rod of the cylinders 41. The extension direction of the slide rail 2 is perpendicular to the pressing path of the vertical pressing mechanism 4. A touch switch 6 is provided on the horizontal base plate 11.

[0023] The end of the slide rail 2 is provided with a limiting block 7. When the positioning fixture 3 is pulled out from the press-fitting station, the limiting block 7 contacts the stop surface at the end of the slider 5, limiting the maximum displacement stroke of the positioning fixture 3 and preventing the positioning fixture 3 from being pulled out excessively, which could lead to the risk of the slider 5 derailing.

[0024] The pressure block 42 is provided with an elastic buffer layer 8 to prevent damage to the wheel surface.

[0025] The positioning fixture 3 is equipped with a handle 9, which the operator holds to push the positioning fixture 3.

[0026] The working process of this utility model is as follows: First, place the front / rear left wheel into the wheel positioning groove 31 on the positioning fixture 3. Place the body on the body contour positioning protrusion 32 of the positioning fixture 3. Manually pre-insert the rotating shaft into the left wheel axle hole. Then, place the right wheel and pre-connect it with the other end of the rotating shaft. Hold the handle 9 and push the positioning fixture 3 to the pressing station. The rear side of the positioning fixture 3 contacts the touch switch 6, generating an electrical signal that is transmitted to the controller. The controller sends a start command to the cylinder 41 of the vertical pressing mechanism 4. The cylinder 41 drives the pressure block 42 to press down on the right wheel, thereby connecting the left wheel and the right wheel to the rotating shaft respectively.
