Embodiment 1

[0052] An automatic press-fitting machine for assembling the bolts of the wheel hub assembly of heavy trucks, including a bracket 10 and a controller 11. The bracket 10 is a bow-shaped bracket. When the bracket 10 is placed vertically, the upper and lower ends of the bracket 10 protrude outward, and the middle position of the bracket 10 faces inward. sunken. The controller 11 is fixed on the side of the bracket 10 . The upper end of the bracket 10 is provided with a pressing device, the lower end of the bracket 10 is provided with a rotating device 12 for supporting the hub assembly and a lifting device 13 for lifting the rotating device 12, and a device for conveying is provided between the rotating device 12 and the pressing device. The conveying device 14 of the wheel hub assembly, the conveying device 14 includes two guide rails 141 which are arranged oppositely and a carrying platform 142 for conveying the wheel hub assembly, each guide rail 141 is provided with a conveyo...

Embodiment 2

[0060] Embodiment 2 has basically the same features as Embodiment 1. The difference is that a rail 20 is fixed on the side wall of the bracket 10, reset sensors 21 are installed at the upper and lower ends of the rail 20, and the upper end surface of the hydraulic platform 161 is fixed to the position of the rail 20. The sensing rod 22 is extended and used to sense the reset sensor 21. The reset sensor 21 is used to position the hydraulic platform 161, which is convenient and intuitive to adjust the lifting displacement of the pressure head 162 in the pressing device, and at the same time can intuitively judge whether the pressing force of the pressing device is within the set value, and the reset sensor 21 can constantly monitor The working state of the pressing device.

Embodiment 3

[0062] A bolt press-fitting method using an automatic press-fitting machine, embodiment 3 adopts the automatic press-fitting machine in embodiment 1 or embodiment 2, comprising the steps:

[0063] Step a, transporting the hub assembly, the operator puts the hub bolts onto the hub assembly on the carrier platform, and the conveying device 14 transports the carrier platform directly under the pressing device;

[0064]Step b, positioning the carrying platform 142, when the roller 153 slides into the limiting groove 1422, the Hall sensor on the roller 153 senses the magnet at the bottom of the limiting groove 1422 and generates a Hall signal, and the Hall sensor sends the signal to the controller , the controller stops the conveying device 14;

[0065] Step c, start the lifting device 13, the controller starts the lifting device 13, the second hydraulic cylinder 132 drives the lifting plate 131 to rise until the positioning rod 133 is positioned in the positioning hole on the carr...

Abstract

The invention relates to a pressing machine, and discloses an automatic pressing machine used for assembling a hub assembly of a heavy-duty truck and an assembling method thereof. The automatic pressing machine comprises a bracket and a controller, wherein the upper end part of the bracket is equipped with a pressing device; the lower part of the bracket is equipped with a rotary device and a lifting device; a conveying device is arranged between the rotary device and the pressing device; the conveying device comprises a carrying table and two guide rails which are oppositely arranged; conveyor belts are arranged on the guide rails; the two ends of the carrying table are separately placed onto the conveyor belts of the two guide rails; a blocking positioning mechanism is fixedly arranged between the two guide rails; the blocking positioning mechanism is in blocking connection to the carrying table, and generates hall induction; and the controller positions the carrying table through ahall signal. The pressing machine adopts the blocking positioning mechanism to position the carrying table; and while conveyed to a position below the pressing device, the carrying table can be blocked and positioned. Through the blocking positioning mechanism, the carrying table is high in positioning precision, so that pressing precision of the hub assembly is improved.

Description

technical field [0001] The invention relates to a press-fitting machine, in particular to an automatic press-fitting machine and a press-fitting method for assembling bolts of a heavy truck wheel hub assembly. Background technique [0002] Heavy trucks carry the huge weight of the car, braking torque, driving torque, and various alternating loads generated during driving, so the wheels must be reliable with the front and rear axle assemblies of the car during use. Connection. According to the structure of the car, the hub bearing assembly and the wheel are connected to the axle through the hub bolt and the hub nut, so that the wheel assembly can realize the power transmission and the load of the car, so the hub bolt is a very important part of the car. part. Due to the high-speed rotation of the wheel and the bumping of the vehicle, the clamping force between the hub bolt and the flange hub will gradually weaken, and eventually the mating threads between the two parts will...
