DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] The clamping arm vehicle receiving device of the present invention includes two opposing clamping arm bodies, each of which includes two opposing clamping arm groups 1-1. Each clamping arm group is composed of two clamping arms. The two clamping arm groups are driven to move synchronously to clamp or release the wheel. The clamping arm groups are connected to the clamping arm power cylinder 1-7 via a rack and pinion transmission mechanism. When the clamping arm power cylinder is actuated, the clamping arm groups also move synchronously. The present invention uses a cylinder to drive the clamping arm group 1-1, which can adapt to various environments within the automobile factory.

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

[0023] Furthermore, the lower portion of the clamping arm group 1-2 is provided with a support bearing 2-1, with each clamping arm being provided with one, for supporting the clamping arm at the lower portion to meet the opening and closing movement 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 an existing gear self-locking connecting rod mechanism to avoid 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 rotary support 2-3 and then installed on the mounting base plate 1-8, that is, the rotary support is installed on the mounting base plate, and the upper gear of the clamping arm is arranged on the rotary support 2-3.

[0028] Furthermore, in some embodiments, in the clamping arm body, the 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 various wheelbases.

[0029] Furthermore, in some embodiments, the 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. Under the drive of the switching vehicle type cylinder 1-9, the rear wheel clamping arm body and its mounting base move on the linear guide rail to adjust the distance from the front wheel clamping arm body to meet the use of vehicle types with various wheelbases. After adjustment into place, it can be used to fix the vehicle type positioning pin assembly 1-10, that is, to fix the rear wheel clamping arm body to the bottom support mechanism, such as a lifting platform.

[0031] Furthermore, in some embodiments, the two clamping arm bodies are located on the lifting platform 1-11. By installing the clamping arm type vehicle receiving device on the lifting platform, it can meet the needs of receiving and placing vehicles at different heights, the lifting stroke can be adjusted, and a suitable transmission walking device can be installed according to needs to meet the horizontal walking movement of multiple stations.

[0033] The process is as follows:

[0034] When receiving the vehicle: a 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 wheel clamping arms, and the locking mechanism is locked after the position switch detects a signal, waiting for the vehicle 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 received. The locking mechanism opens, the clamping arm power cylinder retracts into position, 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 travel mechanism according to actual application requirements, thereby meeting multi-station usage and improving utilization. It is particularly 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.
