Description

Technical Field

[0001] This utility model relates to the field of wheel hub unit assembly technology, specifically a bolt clamping device applied to wheel hub unit assembly. Background Technology

[0002] With the rapid development of the economy, the demand for automobiles is increasing day by day. Traditional manual labor can no longer meet the growing production demand, which puts forward higher requirements for automobile assembly. During the assembly of wheel hubs, bolts need to be placed, rotated and tightened.

[0003] For example, Chinese Patent CN105436871B discloses a floating rotary clamping device for wheel hub bolts, including a bracket assembly. A hydraulic cylinder is mounted on top of the bracket assembly, a pressing device is connected below the hydraulic cylinder, a pressure block is connected below the pressing device, and a connecting pressure block is mounted below the pressure block. A floating rotary device is arranged below the bracket assembly. A process ring is placed on the floating rotary device. The process ring includes an annular process ring body with protrusions. Limiting blocks are fixedly connected to the protrusions, forming bolt mounting positions between adjacent limiting blocks. A handle is provided on the process ring. By combining this equipment with corresponding tooling, workers can complete the assembly of wheel hub bolts in a short time, reducing the labor intensity of workers and shortening the wheel hub assembly cycle. In addition, in the wheel hub assembly process, the pre-pressing treatment of wheel hub bolts by the pre-pressing machine can greatly improve the pass rate of the bolt press-fitting process. Traditional bolt pressing devices usually require manual assistance. After each bolt is tightened, the position needs to be adjusted manually and the bolts in different positions need to be tightened again, which greatly reduces the efficiency of bolt pressing. Therefore, a bolt pressing device for wheel hub unit assembly is proposed to solve the above problems. Utility Model Content

A top frame is fixedly installed at the top of the support columns. A top platform is installed below the top frame. An adjustment seat is provided at the bottom of the top platform. A cylinder is fixedly installed on the outer surface of the top of the adjustment seat. A pressure rod is fixedly installed at the bottom of the output shaft of the cylinder. A mounting platform is installed on the top of the base frame. A wheel hub is mounted on the outer surface of the top of the mounting platform. A support platform is provided at the bottom of the mounting platform. The support platform is fixedly connected to the base frame through bottom columns installed at the four corners of the bottom. A rotating component is provided between the mounting platform and the support platform, and the mounting platform is rotatably connected to the support platform through the rotating component.

[0006] Preferably, a slide rail is fixedly installed at the bottom of the top platform, and the adjusting seat is slidably connected to the slide rail. The adjusting seat drives the pressure rod to move and adjust the position.

[0007] Preferably, a first motor is fixedly installed at the top of the top platform. One end of the output shaft of the first motor is fixedly connected to a bidirectional screw. A connecting frame is sleeved on the outer surface of the bidirectional screw, and the connecting frame is threadedly connected to the bidirectional screw. One end of the connecting frame is fixedly connected to the outer surface of the adjusting seat. When the first motor is started, the bidirectional screw is rotated through the first motor, so that the connecting frame drives the adjusting seat to move symmetrically.

[0008] Preferably, the rotating assembly includes a turntable fixedly installed below the bottom of the mounting platform, and a rotating shaft fixedly installed at the bottom of the turntable. The turntable is rotatably connected to the base frame through the rotating shaft. A second motor is fixedly installed at the bottom of the support platform.
