Automatic inclination lifting mechanism for automobile body correcting machine

Abstract

The invention relates to an automatic inclination lifting mechanism for an automobile body correcting machine. The lower end of the front side of a position limiting support seat (7) is provided with an air cylinder (14) capable of propping and pressing the front side surface of a movable leg (12), when the movable leg (12) is in a vertical standing state, an inclined surface of a trapezoidal lock block (11) is fit with a wedge-shaped surface of a wedge-shaped vertical plate of the position limiting support seat (7), and an oil cylinder (16) and a return spring (17) are connected between a trolley frame (22) of a lifting trolley (3) and a platform (1). The discontinuous time-waste and labor-waste manual operation of the platform inclination ascending and descending is changed into the convenient automatic and continuous operation process through a press key.

Description

technical field [0001] The invention relates to an automatic inclined lifting mechanism of an automobile body correction machine. Background technique [0002] The inclined lifting mechanism is one of the commonly used functional parts of the automobile body correction machine. It is used to lift the working platform of the correction machine. It can not only make one end of the platform tilt down through the unloading of the oil cylinder, so that the repair vehicle can enter the working platform through the slope. , and the platform can be lifted back to the horizontal working state by pressing the oil cylinder. A typical tilt lifting mechanism consists of a platform, fixed legs, movable legs and a lifting trolley. Its working principle is: when the platform is in a horizontal state, the movable legs stand vertically and support the platform together with the fixed legs; Press the oil cylinder to lift the front end of the platform to the suspension of the movable legs, the...

Problems solved by technology

A typical tilt lifting mechanism consists of a platform, fixed legs, movable legs and a lifting trolley. Its working principle is: when the platform is in a horizontal state, the movable legs stand vertically and support the platform together with the fixed legs; Press the oil cylinder to lift the front end of the platform to the suspension of the movable legs, then manually rotate the movable legs to a certain angle and lock them while maintaining the pressure of the oil cylinder, and then make the front end of the platform tilt down through the unloading of the oil cylinder and the self-weight of the platform until the front end of the platform touches the ground , due to its simple structure, economy and applicability, it has a certain user group; but there are also the following problems: 1. Due to the need for manual operation and intermittent work process, it is time-consuming and laborious; The tilt of the platform means that the front end of the platform touches the ground, and the ramp needs to be manually moved and positioned, so there are certain safety hazards; 3. The control device is arranged on the periphery of the platform and has not been fixed. It is often necessary to use a long pipeline that passes through the work area, and the manufacturer delivers It needs to be packaged separately, which brings a lot of inconvenience to production and use; 4. Because the inclination angle of the platform is related to the specifications, it is difficult to realize the generalization of the ramp
