Description
Technical Field
The invention relates to a standardized modularized bearing and positioning device which is applied to a standardized tray conveying system conveying line body module established on the basis of standard aluminum profiles.
Background
The load bearing positioning generally requires different sized designs for different workpieces in the process of accommodating production. In a standardized, modular delivery system, a quick response to various demands is required. In this condition, if no modular design is made, manufacturing, design and production will be time-consuming and if each design is of different dimensions, the risk of instability in the process, assembly, design will be increased.
In the current industry, when the non-standard production line is pressed or leak tested, a special design mode is mostly adopted to meet the requirement. In the manufacturing process, the structure is largely divided into three types.

A maximum of 700mm x 700mm is a standard tray of nominal size.
In order to achieve higher applicability and universality, the integrated universal support module can be subjected to size change, and can be developed from four-wheel double support to six-wheel three support or more, but the design form is unchanged, and the upper support block and the lower support block can be universal.
The specific working process adopting the technical scheme is as follows:
(1) The cylinder transversely pushes a sliding block wheel set moving on the lower supporting block, a second group of bearing wheels and a fourth group of bearing wheels of the sliding block wheel set respectively push an upper supporting block with an inclined surface above to move upwards under the directional action of a guide rod, and simultaneously, the first group of bearing wheels and the third group of bearing wheels horizontally move on the plane of the lower supporting block; the sliding friction is converted into rolling friction by the bearing wheel in the motion process, so that the motion resistance is reduced, and long-term maintenance is not required;

(4) When the sliding block wheel set is returned, the cylinder returns to pull the sliding block wheel set, and the four groups of bearing wheels of the sliding block wheel set respectively push the reverse inclined planes of the upper supporting block and the lower supporting block, so that the function of separating each contact surface can be achieved, and sliding friction between steel contact surfaces can be avoided greatly in theory when the sliding block wheel set is pulled; when the cylinder rod is fully retracted, the load bearing position is returned to the low position, completing an action cycle.
Compared with the prior art, the invention uses rolling friction to replace the previous sliding friction, designs a falling point at the highest lifting position, converts the bearing contact into the surface-surface contact between the metal blocks instead of the pressure acting on the wheel shaft, and utilizes the bearing wheels with different heights to match the inclined planes of the upper supporting block and the lower supporting block to separate the upper supporting block and the lower supporting block outwards when the sliding block wheel set retreats, thereby effectively avoiding the defects caused by the sliding friction; and when each part is close, a more reliable bearing effect can be achieved.
