Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to an improved aluminum alloy wheel hub positioning device. Background Art

[0002] Before turning the aluminum alloy wheel hub, it is necessary to first position and clamp it, which is done on a special fixture. Since aluminum alloy wheels come in different sizes, the center hole diameter and wheel hub height also vary. This requires designing and manufacturing dedicated center hole positioning mandrels for different aluminum alloy wheels. In actual production, positioning mandrels are of various types and varieties. This increases the workload of design, production, debugging, and storage. In the process of wheel hub positioning, an improved aluminum alloy wheel hub positioning device needs to be used for installation;

[0003] Announcement No. CN212329669U discloses an improved aluminum alloy wheel hub positioning device, including a base, a floating shaft, a radial pin, a spring, and a tapered sleeve, characterized in that: a tapered hole is opened at the center of the top of the floating shaft, and at least two stepped through holes are evenly opened along the circumferential direction on the side near the top, the inner diameter of the through hole is larger than the outer diameter, the floating shaft is installed on the base and fastened with screws, the radial pin is installed in the through hole at the upper end of the floating shaft, and the diameter matches the outer diameter of the through hole, the spring is sleeved on the radial pin, and the tapered sleeve is installed in the tapered hole at the upper end of the floating shaft and connected to the floating shaft with bolts;

[0004] There may be two problems when using it. First, when the device is positioning and locking the wheel hub, it only contacts the wheel hub through the radial pin to achieve the clamping operation. However, during the clamping process of the wheel hub, it is difficult to adjust the angle of the wheel hub, which can easily cause it to be out of the clamp and make the clamping effect poor. Second, after the processing is completed, the worker needs to disassemble the previous wheel hub before installing the next wheel hub, which makes the waiting time longer and reduces the work efficiency. Therefore, we propose an improved aluminum alloy wheel hub positioning device. Utility Model Content

[0005] The utility model aims to provide an improved aluminum alloy wheel hub positioning device to solve the existing problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] As a further improvement of the above solution, a sliding groove is provided on the top of the installation box, and the width of the support block is the same as the width of the sliding groove.

[0011] By adopting the above technical solution, the sliding groove is convenient for limiting the support block, so that the support block is difficult to slide out of the sliding groove after being subjected to force, and the sliding of the support block is relatively stable.

[0012] As a further improvement of the above solution, a tooth groove is formed on one side of the sliding block, and the first transmission gear and the second transmission gear are meshed with adjacent tooth grooves.

[0015] As a further improvement of the above solution, a rotation groove is provided on the top of the turntable, and the shape of the limit block is the same as that of the rotation groove.

[0016] By adopting the above technical solution, the rotation groove is convenient for limiting the limit block, so that the installation box is difficult to escape from the rotation groove during the rotation process.

[0017] As a further improvement of the above solution, an internal thread is provided on the inner side of the solid sleeve, and the threaded rod is meshed with the internal thread.

[0018] By adopting the above technical solution, the internal thread makes it easy for the solid sleeve to be connected to the threaded rod after rotation, so that after the processing of the wheel hub is completed, the solid sleeve can be controlled to rotate and disengage from the threaded rod, so that the next wheel hub can be directly installed on the outside of the threaded rod through the solid sleeve after clamping, so that the intermittent time of the device is shorter, thereby improving work efficiency.

[0021] (2) The utility model is an improved aluminum alloy wheel hub positioning device. After the wheel hub is clamped, the rotating assembly is set. The wheel hub is relatively large. If multiple positions need to be processed, the staff needs to move around. The device clamps more stably and can control the second motor to drive the installation box to rotate, so that the limit block slides between the inner sides of the turntable, making it difficult for the installation box and the turntable to separate, making the connection more stable, and thus preventing the installation box from shaking during rotation.
