The present application adopts a cylinder to drive the clamping arm group 1-1, which can adapt to various environments in the automobile factory.

[0022] Furthermore, in some embodiments, the rack and pinion transmission mechanism comprises a double-sided rack 1-4 connected to the clamping arm power cylinder, two relatively arranged transition gears 1-2 meshing with the two teeth of the double-sided rack, and two groups of clamping arm lower gears 2-2 meshing with the two transition gears; each group of clamping arm lower gears 2-2 comprises two, the two clamping arm lower gears 2-2 meshing with each other and respectively connected to a clamping arm of a clamping arm group 1-1, and one clamping arm lower gear 2-2 meshes with one transition gear 1-2.

[0023] Furthermore, the lower part of the clamping arm group 1-2 is provided with a support bearing 2-1, and each clamping arm is provided with one support bearing, which is used to support the clamping arm at the lower part to meet the opening and closing action and support requirements of the clamping arm.

[0024] Furthermore, in some embodiments, the double-sided rack 1-4 is arranged on a linear guide rail 1-5, the linear guide rail 1-5 is fixed on a mounting base plate 1-8, the clamping arm power cylinder 1-7 is mounted on the mounting base plate 1-8, the front end of the clamping arm power cylinder is connected to the double-sided rack 1-4, and the clamping arm group 1-1 is located on both sides of the mounting base plate.

[0025] Furthermore, in some embodiments, a locking mechanism 1-6 can be provided on one side of the double-sided rack 1-4, and the locking mechanism is connected to a lower gear 2-2 of a clamping arm. The locking block at the front end thereof can be driven to be inserted into the tooth groove to prevent the lower gear 2-2 of the clamping arm from rotating. The locking mechanism 1-6 can be selected to be implemented by an existing gear self-locking connecting rod mechanism, thereby avoiding the situation where the clamping arm is automatically opened due to the vehicle body.

[0026] Furthermore, in some embodiments, a switch 1-3 for detecting the opening and closing of the clamping arm is provided on one side of the double-sided rack 1-4, which is used to detect the opening and closing status of the clamping arm. The switch 1-3 for detecting the opening and closing of the clamping arm can be implemented by an infrared switch, or other available detection switches.

[0027] Furthermore, in some embodiments, the lower gear 2-2 of the clamping arm is connected to the swivel support 2-3 and then installed on the mounting base plate 1-8, that is, the swivel support is installed on the mounting base plate, and the upper gear of the clamping arm is arranged on the swivel support 2-3.

[0028] Furthermore, in some embodiments, in the clamping arm body, a rear wheel clamping arm body for clamping the rear wheel of the vehicle is connected to a vehicle type switching cylinder 1-9. Driven by the vehicle type switching cylinder 1-9, it can be displaced relative to the front wheel clamping arm body for clamping the front wheel of the vehicle to change the distance between the two clamping arm bodies, thereby meeting the use of vehicle types with a variety of wheelbases.

[0029] Furthermore, in some embodiments, a vehicle type positioning pin assembly 1-10 is arranged on the mounting base of the rear wheel clamping arm body, and the vehicle type positioning pin assembly 1-10 is at least two groups, which are arranged on both sides of the clamping arm power cylinder and are arranged symmetrically.

[0030] Furthermore, in some embodiments, the mounting base of the rear wheel clamping arm body is arranged on the corresponding linear guide rail.

[0033] The process is as follows:

[0034] When receiving the car: the signal is transmitted through the external vehicle model identification switch to switch the vehicle model, the lifting platform rises to its position, the clamping arm power cylinder extends, drives the double-sided rack to move, and the rack drives the lower gear of the clamping arm to rotate through the transition gear to achieve the rotation of the clamping arm, the front and rear wheels are clamped by the clamping arm, and the locking mechanism is locked after the signal from the in-position switch is detected, waiting for the car body to be placed on the clamping arm.

[0035] When releasing the car: the lifting platform descends, the car body is placed on the plate chain, and the in-position signal feedback is obtained. The locking mechanism opens, the clamping arm power cylinder retracts into place, the lifting platform descends to the bottom, and the car is released.

[0036] The device of the present invention can be equipped with a suitable walking mechanism according to actual application requirements, thereby meeting the use of multiple stations and improving the utilization rate. The device is more suitable for applications with complex processes and harsh working environments. The device of the present invention is easy to manufacture, assemble, transport, install, and maintain.
