Description

Technical Field

[0001] The utility model relates to the technical field of automatic press-fitting of automobile wheel hub unit bolts, in particular to an automatic press-fitting device for automobile wheel hub unit bolts. Background Art

[0002] During the processing of automobile wheel hub unit bolts, a device for pressing the bolts is used. In the existing automatic pressing device for automobile wheel hub unit bolts, the mold is placed on the workbench and is simply fixed. The fixing effect is not good, and it is easy to shift during the pressing process. It is not easy to fix when using molds of different sizes, and it is necessary to replace the fixture for fixing. Therefore, we propose an automatic pressing device for automobile wheel hub unit bolts.

[0003] The existing patent (Announcement No.: CN219617602U) discloses an automatic press-fit device for automobile hub unit bolts. By setting a clamp block, the threaded rod will drive two movable blocks to move closer to each other when rotating. The movable block will slide on the slide rod. The slide rod can ensure that the movable block can move linearly. Then the two clamp blocks are close to each other to clamp and fix the mold. The opening size of the clamp block can be adjusted by rotating the threaded rod, so as to clamp and fix molds of different sizes. In the process of implementing this solution, it is found that the following problems exist in the prior art and have not been well solved:

[0004] Although the device can be automatically centered during use, it requires workers to operate back and forth to perform clamping work. The clamping operation is cumbersome and brings a huge workload to the workers. In addition, the wheel hub size cannot be automatically adjusted during use, which affects work efficiency. Utility Model Content

[0005] In order to improve the above-mentioned problem that the wheel hub clamping work needs to be manually clamped by the staff and cannot be automatically adjusted according to the wheel hub size, the utility model provides an automatic press-fitting device for automobile wheel hub unit bolts.

[0006] The utility model provides an automatic press-fit device for automobile hub unit bolts, which adopts the following technical solutions:

[0008] The inner side of the linkage plate is connected with a second sliding block, the other side of the second sliding block is connected with a side plate, the center of the side plate is connected with a connecting rope, and the other side of the connecting rope is sleeved on the surface of the driving motor.

[0009] Through the above technical solution, it is convenient to drive the linkage plate to move through the connecting rope, so that the linkage plate automatically moves toward the center, automatically limits the clamping of the mold, and at the same time the connecting rope also drives the side plates to automatically gather together to complete the adjustment work, so that it automatically adapts to the mold size.

[0010] Optionally, in the above-mentioned automatic press-fitting device for automobile hub unit bolts, the device body and the base are installed in an integrated manner, fixing blocks are symmetrically distributed on both sides of the base, and the center point of the base coincides with the center point of the press-fitting mechanism.

[0011] The above technical solution makes it easy to align the base with the press-fitting mechanism, thereby facilitating the subsequent press-fitting of the wheel hub bolts.

[0012] Optionally, in the above-mentioned automatic press-fitting device for automobile hub unit bolts, the connection between the connecting rope and the driving rod is a rotational connection, the connecting rope passes through the center of the linkage plate, and the connecting rope is installed in an integrated manner with the side plate.

[0013] Through the above technical solution, it is convenient to pull the side panels through the connecting ropes so that the side panels move toward the center direction, thereby completing the automated movement of the side panels.

[0014] Optionally, in the above-mentioned automatic press-fitting device for automobile hub unit bolts, the side panel is connected to the second sliding block by hot-melt connection, the second sliding block is connected to the linkage plate by sliding connection, and the side panels are symmetrically distributed on both sides of the linkage plate.

[0015] Through the above technical solution, it is convenient to drive the side plate to move through the second sliding block, thereby assisting the automatic movement of the side plate.

[0016] Optionally, in the above-mentioned automatic press-fitting device for automobile wheel hub unit bolts, the linkage plate and the first sliding block are connected by hot-melt connection, the first sliding block and the sliding groove are connected by sliding connection, and the first sliding blocks are symmetrically distributed on both sides of the base.

[0017] Through the above technical solution, it is convenient to utilize the linkage plate to cooperate with the first sliding block so that the linkage plate can move, thereby completing the automatic clamping of the mold.

[0018] Optionally, in the above-mentioned automatic press-fitting device for automobile hub unit bolts, the fixing block and the return spring are installed in an integrated manner, the fixing block forms a spring return structure with the linkage plate through the return spring, and the linkage plate and the return spring are installed in an integrated manner.

[0019] Through the above technical solution, it is convenient to utilize the reset spring so that after the clamping work is carried out, the reset spring drives the linkage plate to reset, which is convenient for subsequent work.

[0020] In summary, the present invention has at least one of the following beneficial effects:

[0021] A driving motor and a connecting rope are arranged inside the base. When in use, the driving motor drives the connecting rope to rotate, so that the connecting rope tightens the linkage plate, so that the linkage plate moves through the first sliding block and automatically approaches the mold to complete the fixed limit work. After processing, the connecting rope loosens the linkage plate, and the reset spring drives the linkage plate to reset and wait for the next work to be carried out. The structure is simple and the degree of automation is high.

[0022] By arranging a second sliding block and a side plate on both sides of the linkage plate, the side plates are driven to move while the connecting rope tightens the linkage plate and gathers toward the center, thereby automatically limiting the two sides of the mold and automatically adjusting the distance to ensure the fixation of the mold. There is no need for manual adjustment by the staff, ensuring easy operation. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting rope 4 passes through the center of the linkage plate 6. The connecting rope 4 and the side plate 5 are installed in an integrated manner.
