Description

Adjustable tray for multi-size workpieces

Technical Field

The utility model relates to a special tray especially relates to an adjustable tray that is used for many sizes work piece. Belongs to the technical field of special transfer trays.

Background

The conventional tray is square or rectangular, and the bearing structure is a square or rectangular flat base plate, and feet forming sockets are arranged below the flat base plate so as to be used for loading, unloading, transporting and transporting equipment such as a forklift and a three-dimensional warehouse stacker. The basic forms of stacking of goods on pallets are block stacks, brick stacks and cross stacking. In order to ensure that the stacking box is not easy to collapse, the stacking box is generally stacked into a square with four corners corresponding to each other up and down.

However, the special pallet in the production process is only suitable for workpieces with fixed shapes and specifications, and cannot simultaneously meet the supporting and fixing requirements of workpieces with various sizes.

Disclosure of Invention

The utility model aims to provide a: aiming at the limitations existing in the prior art, the adjustable tray for the workpieces with multiple sizes is provided, so that the requirements of bearing and transferring the workpieces with different sizes are met.

In order to achieve the above object, the utility model discloses a basic technical scheme that is used for the adjustable tray of many sizes work piece is: the tray unit comprises an upper supporting plate supported on the lower supporting plate through a positioning column, two parallel slide rails are fixed on the upper surface of the upper supporting plate, two axially-constrained symmetrical two-way screw rods supported on the upper supporting plate are arranged between the two parallel slide rails, the slide rails form a sliding pair through a slide block and two opposite clamping and positioning blocks, opposite surfaces of the clamping and positioning blocks are upper expansion inclined surfaces, the two opposite upper expansion inclined surfaces are closed to form a V-shaped structure, the middle of the upper expansion inclined surfaces are sunken to form a supporting platform, and nuts forming a spiral pair with the two-way screw rods are arranged at the bottoms of the clamping and positioning blocks.

Before transferring, a workpiece to be transferred is placed between the two clamping and positioning blocks, the bidirectional screw rod is rotated to enable the workpiece to be clamped and positioned by relative displacement, and then transferring can be carried out. Therefore, the utility model discloses be suitable for the support and the fixed of multiple size work piece in the certain limit, have good adaptability.

The utility model discloses a further perfection is, supporting platform comprises the outer inclined plane that expands of horizontal holding surface, vertical spacing face and both sides.

The utility model discloses a further perfection is, the cross-section of slide rail is omega shape.

The utility model discloses further perfect is, the crank is equipped with to the one end of two-way lead screw.

The utility model discloses a further perfection is, the bottom plate is the square.

Detailed Description

The adjustable tray for the multi-size workpiece in the embodiment is composed of a plurality of tray units, each tray unit is shown in fig. 1-6 and comprises an upper supporting plate 3 supported on a square lower supporting plate 1 through a positioning column 2, two parallel slide rails 4 with omega-shaped cross sections are fixed on the upper surface of the upper supporting plate 3, an axially-constrained symmetrical two-way screw 8 supported on the upper supporting plate 3 through a mounting block 10 is arranged between the two parallel slide rails 4, a crank 9 is arranged at one end of the two-way screw 8, and the slide rails 4 and two opposite clamping and positioning blocks 6 form a moving pair through a slide block 5. The opposite surface of the clamping and positioning block 6 is an upper expanding inclined surface 6-1, the two opposite upper expanding inclined surfaces 6-1 are in a V shape after being folded, the middle part of the upper expanding inclined surface 6-1 is sunken to form a supporting platform 7, and the supporting platform 7 is composed of a horizontal supporting surface 7-1, a vertical limiting surface 7-3 and outer expanding inclined surfaces 7-2 at two sides. The bottom of the clamping and positioning block 6 is provided with a nut 6-2 which forms a screw pair with the bidirectional screw 8.

When the workpiece transferring device is used, a workpiece to be transferred is loaded on the supporting platforms of the two clamping and positioning blocks, the crank is rotated to drive the bidirectional screw rod to rotate, the two clamping and positioning blocks are enabled to relatively displace, and the workpiece can be transferred until the workpiece is clamped and positioned.

Compared with the prior art, the adjustable tray of this embodiment has following apparent advantage:

1) by means of the clamping positioning blocks at the two ends, various workpieces with fixed lengths and sizes varying within a certain range can be supported;

2) the supporting platform is provided with the outward-expanding inclined planes on two sides, so that the supporting platform is suitable for clamping workpieces with curved surfaces at two ends and workpieces with width sizes varying in a certain range;

3) the bidirectional screw mechanism ensures the centering of clamping, so that the workpiece is very stable in the transfer process;

4) the slide block moves stably and reliably on the slide rail with the omega-shaped section matched with the slide block.

In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations are included in the scope defined by the claims of the present invention.
