In order to achieve the above purpose, the utility model adopts the following technical scheme:

an adjustable self-adaptive supporting device comprises a fixed seat, wherein a fixed rod is fixedly connected to the fixed seat, and a movable rod capable of ascending and descending is sleeved in the fixed rod; the top of the moving rod is fixedly connected with a nut, and a lead screw matched with the nut is sleeved in the nut; the top of the lead screw is rotatably connected with a top cover; the lead screw up end is the sphere, top cap bottom is equipped with the sphere recess that uses with lead screw up end clearance fit.

Preferably, the upper end of the screw rod is in clearance fit connection with an opening pressing plate, and the opening pressing plate is fixedly connected with the top cover through screws.

Preferably, the fixed rod is provided with a fixed hole, and the movable rod is uniformly distributed with a plurality of height adjusting holes matched with the fixed hole; the adjustable self-adaptive supporting device further comprises a fixing rod, and the fixing rod is inserted into the fixing hole after the fixing hole and the height adjusting hole are aligned for fixing.

Preferably, the adjustable self-adaptive supporting device further comprises a pull rod, one end of the pull rod is provided with a cotter pin, and the pull rod is fixedly connected with the screw rod through the cotter pin.

The utility model has the advantages as follows:

1. the utility model discloses an up end is the lead screw of sphere and the top cap that uses rather than clearance fit, can increase the area of contact of top cap and support workpiece according to the angle that the top cap can be adjusted to the holding surface condition of support workpiece, makes the atress of support workpiece more even, supports more stably.

2. The utility model discloses a cooperation through altitude mixture control hole and fixed orifices after the carriage release lever upwards mentions realizes the coarse adjustment, realizes the micro-adjustment through screw and lead screw, and the operation is quick, accurate, its simple structure, and stability is high, and the cost is low.

FIG. 2 is a schematic structural view of the present invention during use;

fig. 3 is an enlarged schematic view of a structure at a in fig. 2.

Shown in the figure: 1-top cover, 2-opening pressing plate, 3-screw, 4-pulling rod, 5-opening pin, 6-nut, 7-leading screw, 8-fixed rod, 9-movable rod, 10-height adjusting hole, 11-fixed seat, 12-supporting workpiece and 13-fixed hole.

Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

As shown in fig. 1-3, an adjustable adaptive supporting device includes a fixed base 11, a fixed rod 8 is fixedly connected to the fixed base 11, and a movable rod 9 capable of ascending and descending is sleeved in the fixed rod 8; the top of the moving rod 9 is fixedly connected with a nut 6, and a lead screw 7 matched with the nut 6 is sleeved in the nut 6; the top of the screw rod 7 is rotatably connected with a top cover 1; the lead screw 7 up end is the sphere, top cap 1 bottom is equipped with the sphere recess that uses with lead screw 7 up end clearance fit. The device has the advantages of simple structure, capability of saving production cost, capability of quickly and greatly roughly adjusting the supporting height, fine adjustment and accurate adjustment, capability of meeting various supporting requirements, wide application range and multiple purposes due to the large height adjusting range, and capability of improving the supporting efficiency. In addition, the upper top cover can adjust the supporting direction according to the angle or the shape of the supporting workpiece, and the maximization of the contact area is ensured.

The upper end of the screw rod 7 is in clearance fit connection with an opening pressing plate 2, and the opening pressing plate 2 is fixedly connected with the top cover 1 through a screw 3. The structure can lead the top cover to incline at the top of the screw rod within a certain angle range, can meet the requirement of supporting inclined supporting workpieces or supporting workpieces with uneven supporting surfaces, and leads the contact surface to be larger and the stress to be more uniform.

The fixed rod 8 is provided with a fixed hole 13, and the moving rod 9 is uniformly distributed with six height adjusting holes 10 matched with the fixed hole 13.

The working process of the utility model is as follows:

will the utility model discloses a lead screw 7 transfers the extreme low position, moves to support work piece 12 below, and manual mentions the carriage release lever 9 and makes fixed orifices 13 on the dead lever 8 and the altitude mixture control hole 10 on the carriage release lever 9 align the back and insert the fixed orifices 13 and the altitude mixture control hole 10 of alignment with the fixed rod in. The screw rod 7 is slowly lifted by rotating the pull rod 4 to drive the top cover 1 to lift together, the top cover 1 contacts with the supporting workpiece 12 and then contacts with the supporting noodle piece of the supporting workpiece 12, and the pull rod 4 is continuously rotated until the top cover 1 and the supporting workpiece 12 are in close contact.

The above embodiments are only used for illustrating but not limiting the technical solutions of the present invention, and although the present invention is described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: the present invention may be modified or substituted with equivalents without departing from the spirit and scope of the invention, which should be construed as being limited only by the claims.
