Description

Movable supporting mechanism

Technical Field

The utility model relates to an automatic change transmission equipment subassembly, be used for supporting the movable member to remove supporting mechanism toward the long, short distance transfer of each target location specifically says so.

Background

In the design process of an automatic mechanical structure, the movable component is required to be horizontally transferred between different positions. The horizontal transfer of the movable member requires a support mechanism. The supporting mechanism is used for counteracting the gravity of the movable member, so that the movable member is always kept at the height of a horizontal plane, and meanwhile, the resistance to the horizontal transfer of the movable member needs to be reduced as much as possible, thereby providing a precondition for the horizontal transfer of the member. The support structure for the movable member mainly has two forms of sliding friction and rolling friction, the biggest problem of the sliding friction is that the resistance to the member is large, the member and the support surface have to be processed with high precision in order to reduce the resistance, and the final cost is high, and the sliding friction is not suitable for the member with a large contact area. So the most used is the form of rolling friction.

At present, the existing rolling friction type supporting mechanism has two forms of a rolling bearing supporting mechanism and a traditional universal ball supporting mechanism. However, the rolling bearing support mechanism can only be applied to the situation that the component is fixed in the transfer direction, and if the component transfer direction needs to be changed, the bearing support type cannot meet the requirement. As shown in fig. 1, a conventional universal ball support mechanism mainly includes a movable member and a fixed platform, universal balls are uniformly distributed on the fixed platform corresponding to the moving direction of the movable member, and the bottom surface of the movable member abuts against the universal balls. The universal ball in the traditional universal ball supporting mechanism is installed upwards, dust and dirt are easy to accumulate, and the accumulated dust and dirt are very easy to clamp the universal ball to cause the universal ball to be invalid. In addition, the bottom surface of the movable member is large, and the processing cost of the whole bottom surface is high, so that the bottom surface of the movable member is generally an unprocessed surface and uneven, and the bottom surface of the movable member in the traditional universal ball supporting mechanism is directly abutted against the universal balls, so that the contact between the bottom surface of the movable member and the plurality of universal balls is not coplanar, and the transfer of the movable member is not stable. Meanwhile, the conventional universal ball support mechanism has no guide, resulting in inaccuracy in the moving direction of the movable member. In addition, the conventional universal ball support mechanism needs to arrange a plurality of rows of ball supports in the moving direction of the moving member to realize mutual connection of moving member transfer, if the size of the transferred member is small, the arrangement density of the ball supports on the support platform needs to be large, and if the member needs to be transferred for a long distance, the number of the rows of the ball supports needs to be arranged on the transfer route, so that the manufacturing cost with the whole support is high.

The guide wheel is positioned in the groove, a gap is reserved between the lower surface of the guide wheel and the bottom of the groove, and the wheel surface of the guide wheel is in rolling fit with the side wall of the groove. The upper surface of the fixed platform corresponding to the universal ball group is provided with a horizontally arranged supporting rail which is parallel to the first section body, universal balls in the universal ball group are all propped against the upper surface of the supporting rail, and the universal balls are all in rolling fit with the supporting rail.
