Description

Technical Field

[0001] The utility model belongs to the technical field of pallets, in particular to a welding fixture for lifting pallets. Background Art

[0002] Pallets are important loading, unloading, storage and transportation equipment in the logistics process. They are used in conjunction with forklifts and play a huge role in modern logistics. Pallets are welded to the lifting mechanism to form lifting pallets.

[0003] The manufacturing process of the lifting pallet is as follows: the pallet is welded to the lifting mechanism through welding fixtures, thereby realizing the production of the lifting pallet. During the welding process of the lifting pallet, it is necessary to control the welding fixture to limit the position of the lifting mechanism and the pallet, thereby improving the stability of the lifting mechanism and the pallet during the welding process. The welding fixture is composed of a hydraulic cylinder, a hydraulic rod, a clamp and a rubber pad.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. During use, the existing welding fixture operates the hydraulic cylinder to extend or retract the hydraulic rod, thereby adjusting the distance between the two clamping blocks to limit the position of the lifting mechanism and the pallet. However, this is not convenient for multi-directional positioning of the pallet, which reduces the stability of the pallet after the position is determined, thereby affecting the welding process of the pallet.

[0006] 2. The existing welding fixture uses the same set of clamps to lock the position of the lifting mechanism and the pallet during use. However, when the sizes of the lifting mechanism and the pallet are inconsistent, it is not convenient to use the same set of clamps to limit the position of the lifting mechanism and the pallet at the same time, thereby reducing the practicality of the existing welding fixture.

[0007] To this end, we provide a welding fixture for lifting pallets to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to provide a welding fixture for lifting pallets. By setting a positioning component and an auxiliary component, the problem that the existing welding fixture is not convenient for simultaneously limiting the position of the pallet in multiple directions and has poor practicality is solved.

[0009] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0010] The top end face of described sliding panel also is provided with an interlock plate, and the interlock plate is hinged on the base plate, is fixed with a backing pin on the interlock plate, and an end of sliding panel withstands on the backing pin of interlock plate.

[0011] The utility model is further configured such that a through hole is opened on the side wall of the movable shaft, the rotating rod threadedly connected to the fixed cylinder is plugged into the through hole, and the fixed cylinder is hollow.

[0012] The utility model is further configured such that a sliding block is connected to the side wall of the bracket, a sliding groove is provided on the base plate, and the sliding block is slidably connected to the sliding groove.

[0013] The utility model is further configured such that a through slot is provided on the placement plate, the upper end of the screw fixed to the positioning block passes through the through slot, and the limiting nut threadedly connected to the peripheral side wall of the screw contacts the side wall of the placement plate.

[0014] The present invention is further configured such that a guide groove is provided on the side wall of the placement plate, and a guide block fixed on the side wall of the movable seat is slidably connected to the guide groove.

[0015] The utility model is further configured such that the end of the lead screw is fixedly connected to a turning handle, and a screw threadedly connected on the end surface of the turning handle is threadedly connected to the ear seat.

[0016] The utility model is further configured such that a placement assembly is provided on the side wall of the base plate, a mounting plate in the placement assembly is sleeved on the side wall of the base plate, a positioning rod is fixedly connected to the lower surface of the mounting plate, and a bolt threaded on the mounting plate passes through the positioning rod.

[0017] The present invention is further configured such that the mounting plate is in a U-shape, the positioning rods are in a hollow structure, and the positioning rods are arranged in a rectangular array.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model sets a positioning component and starts the hydraulic cylinder. When the hydraulic rod contracts, the connecting plate works, one end of the placement plate presses down against the pallet, and the positioning block limits the side of the pallet, thereby limiting the position of the pallet in multiple directions, thereby improving the stability of the pallet after the position is limited, and thus better welding the pallet.

[0020] 2. The utility model sets an auxiliary component. When the placement plate moves, the clamping block moves with the movement of the placement plate, and the clamping block contacts the side wall of the lifting mechanism, thereby limiting the position of the side of the clamping block, and turning the handle to adjust the position of the clamping block, thereby limiting the position of lifting mechanisms of different sizes, thereby better welding the pallet to the lifting mechanism.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
