Driving mechanism motion direction conversion device and method

Abstract

The invention discloses a driving mechanism motion direction conversion device and method. The driving mechanism motion direction conversion device comprises a fixed frame, a movable frame and a power source; a guide wheel is mounted on the movable frame; a guide rail is mounted on the fixed frame; the power source can drive the guide wheel to move in the guide rail; a connecting rod mechanism is connected between a tailstock of the power source and the movable frame; and when the guide wheel passes through a guide rail bend, the connecting rod mechanism can drive the movable frame to move on the fixed frame, and the movable frame can drive the guide wheel to longitudinally move in the guide rail relative to the linear part of the guide rail. According to the driving mechanism motion direction conversion device and method, conversion of the motion direction of a driving mechanism is achieved, vertical plugging and pulling can be conducted, and the problems caused by the fact that the power source is directly fixed to the movable frame are solved.

Description

technical field [0001] The invention relates to the field of drive equipment, in particular to a device and method for converting the motion direction of a drive mechanism. Background technique [0002] At present, the general power source can only drive the object to move in a straight line along the axis of the power source, but when the object encounters an inflection point when moving in a straight line, there will be a problem of changing direction. The traditional method is that the tailstock of the power source is fixedly connected with the movable frame, and then Utilizing the power source and the extrusion of the curved part of the track at the front end of the drive, the reaction force is decomposed and acts on the guide wheels and sliders on the movable frame to drive the movable frame to move longitudinally relative to the fixed frame, that is, the guide wheels and sliders at this time On the one hand, it moves laterally relative to the movable frame, and also mo...

Problems solved by technology

[0003] The above method will bring the following problems: 1. If the customer requests to increase the distance of the sliding door, when the sliding door is required to be vertically sliding, the upper guide rail needs to be made 90 degrees in the curve, and the extrusion force cannot produce the direction force of the sliding door, resulting in Unable to move the Sierra, that is, the existing products cannot be made into a vertical Sierra, which cannot meet the needs of customers;

[0004] 2. Since the force in the movement direction of the plug comes from the component force of the power source, the generated plug force is very small, resulting in poor sealing of the lower device behind the plug. Similarly, if the power source drive has reached the bottom, inflate in the opposite direction to meet the needs When the air pressure is pushed or pulled, it takes a certain amount of time, causing the Sierra to freeze;

[0005] 3. The power source is fixed on the movable frame, and the reaction force of the push-pull force of the cylinder all acts on the movable frame, causing the movable frame to be easily deformed;

[0006] 4. Since the pull force of the plug comes from the component force of the power source, to increase the pull force of the plug, the diameter of the cylinder or the air pressure or the slope of the upper track must be increased, which will increase the pressure on the inner slope of the upper guide rail and easily damage the slope of the upper guide rail , and increasing the diameter of the cylinder, it may not be able to meet the overall installation requirements of the device, which will bring difficulties to the design of the overall device
