Description

Technical Field

[0001] The utility model relates to a pallet, in particular to a pallet adaptable to workpieces of multiple sizes, belonging to the technical field of workpiece transportation. Background Art

[0002] According to the applicant's understanding, conventional pallets are mostly square or rectangular, and have socket legs at the bottom of the pallet. After the goods are stacked on the pallet, they can be loaded and unloaded, transported and transferred within the warehouse by forklifts, three-dimensional warehouse stackers and other equipment. The disadvantage is that the size is large, and it is difficult to position and fix the workpieces placed on the pallet, which makes it possible to shake or even overturn during transportation. In addition, it cannot simultaneously meet the positioning and fixation of workpieces of multiple sizes. Summary of the invention

[0003] The purpose of the utility model is to propose a pallet for workpieces of various sizes, which can stably place the workpieces and safely transport the workpieces, thereby meeting the requirements for carrying, fixing and transporting workpieces of different sizes.

[0004] To achieve the above-mentioned purpose, the basic technical scheme of the pallet that the utility model is suitable for workpieces of multiple sizes is as follows: it includes a base plate, a slide rail extending in a fixed length direction on the upper surface of the base plate, and the slide rail is provided with a plurality of pairs of positioning blocks that respectively form moving pairs therewith, and the opposite end faces of the paired positioning blocks respectively have clamping recesses, and the outer side of each paired positioning block 7 is respectively provided with a spring fixing seat fixed on the symmetrical center line of the base plate, and the spring fixing seat is provided with a spring whose inner end is fixed thereto and whose outer end abuts against the outer side of the corresponding positioning block.

[0005] A further improvement of the utility model is that two symmetrically arranged parallel slide rails are fixed on the upper surface of the base plate, and an even number of sliders forming a moving pair therewith are respectively mounted on the two slide rails, and the upper surface of each slider is fixedly connected to a positioning block through a connecting block.

[0006] A further improvement of the utility model is that the clamping recess of the positioning block is formed by a V-shaped notch at the bottom that is expanded and transitioned on the curved surface to a semicircular notch at the top.

[0007] A further improvement of the utility model is that after the paired positioning blocks are matched, the top surface and bottom surface projections thereof are respectively circular and rhombus-shaped.

[0008] In this way, when the workpiece to be transported is inserted into the clamping recess between the paired positioning blocks, the spring on the outside thereof is compressed, so that the workpiece can be reliably clamped and positioned after insertion, and can be safely transported, with good adaptability.

[0015] This embodiment is suitable for pallets of workpieces of multiple sizes such as Figures 1 to 4 As shown, it is composed of a base plate 1, a slide rail 2, a slider 3, a connecting block 4, a spring fixing seat 5, a spring 6, and a positioning block 7.

[0016] Two parallel slide rails 2 extending in the length direction are fixed to the upper surface of the bottom plate 1 by bolts. The two parallel slide rails 2 are symmetrically arranged along the width direction of the bottom plate 1 .

[0017] Six sliders 3 are respectively installed on the two slide rails 2 to form a moving pair with them. The upper surface of each slider 3 is connected to a positioning block 7 through a connecting block 4. The positioning block 7, the connecting block 4 and the slider 3 are fastened by bolts, so the slide rail 2 also forms a moving pair with the positioning block 7 through the slider 3. The six positioning blocks 7 are paired in pairs, and the opposite end faces of the paired positioning blocks 7 have a clamping concave formed by a bottom V-shaped notch extending through a curved surface to a top semicircular concave notch. Therefore, after the two pairs of positioning blocks 7 are matched, the top and bottom projections are circular and rhombus-shaped, respectively.

[0018] A spring fixing seat 5 is respectively installed on the outer side of each paired positioning block 7 and fixed on the symmetrical center line of the base plate 1 by bolts. The spring fixing seat 5 is equipped with a spring 6 whose inner end is fixed thereto and whose outer end abuts against the outer side of the corresponding positioning block 7.

[0019] During use, when the workpiece to be transported is inserted into the clamping recess between the paired positioning blocks, the spring on the outside is compressed, causing the two positioning blocks to adaptively move in opposite directions, ultimately allowing the workpiece to be reliably clamped and positioned after insertion, and can be safely transported.

[0020] Tests show that, compared with the prior art, the pallet of this embodiment has the following advantages:

[0021] 1) The paired positioning blocks can be displaced within the expansion and contraction range of the spring, so they can clamp a variety of workpieces with fixed sizes varying within a certain range;

[0022] 2) The relative displacement position of the positioning block is adjusted according to the size of the workpiece, without manual intervention, which is very convenient;

[0023] 3) The elastic clamping positioning of the positioning block effectively avoids the shaking or overturning of the workpiece during transportation, ensuring stable transportation;

[0024] 4) The top and bottom projections of the positioning block are circular and diamond-shaped clamping recesses respectively, which can adapt to curved workpieces and workpieces with diameters varying within a certain range, and have ideal adaptability.

[0025] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation is included in the scope defined by the requirements of the present invention.
