Description

Technical Field

[0001] The utility model relates to the technical field of pallet production, and more specifically, to a pallet production positioning bracket. Background Art

[0002] Positioning brackets in pallet production are key components used to ensure accuracy and stability during the pallet manufacturing process. Their primary function is to secure the pallet's position, preventing movement or offset during processing or assembly, thereby ensuring the pallet's quality and dimensional accuracy. Currently, during the production assembly process, operators place electronic components on pallets, which are then placed on the feed platform of automated production equipment for automatic assembly. This allows for batch feeding and improves production efficiency.

[0003] In the existing technology, such as the document with publication number CN219787259U, a pallet production positioning bracket is specifically disclosed. Although the device in the document can rotate the rotating wheel to make the rotating wheel contact with the ground to facilitate the movement of the support frame, after the support frame moves to the designated workstation, the suction cup is rotated out to contact the ground to achieve positioning of the support frame, thereby achieving switching between the rotating wheel and the suction cup. However, each switching process requires manual operation, and multiple rotating wheels need to be operated one by one, which undoubtedly increases the complexity of the operation. This operation method not only affects the overall work efficiency, but may also cause inaccurate positioning due to manual operation, affecting the stability of the production process and product quality. For this reason, we propose a pallet production positioning bracket. Utility Model Content

This operation method not only affects the overall work efficiency, but may also cause inaccurate positioning due to manual operation, affecting the stability of the production process and the technical problem of product quality.

[0005] The utility model proposes a pallet production positioning bracket, including a positioning plate, wherein both sides of the positioning plate are fixedly connected to support frames, and both sides of the two support frames are fixedly connected to support plates, and two rotating shafts are fixedly connected between the two support plates located on the same side, and the outer walls of the two rotating shafts are rotatably connected to connecting arms, the bottoms of the two connecting arms are rotatably connected to mounting frames, the inner walls of the two mounting frames are rotatably connected to rollers, the outer walls of the two connecting arms are fixedly connected to a first hinge seat, the inner walls of the two first hinge seats are rotatably connected to a rotating arm, and the ends of the two rotating arms are rotatably connected to a second hinge seat.

[0006] Preferably, the two support plates on the same side are fixedly connected with two fixed blocks in a symmetrical structure, and the two fixed blocks on the same side are rotatably connected with a bidirectional threaded rod, and the ends of the bidirectional threaded rod pass through the two second hinge seats and are threadedly connected thereto.

[0007] Preferably, the outer walls of the plurality of support plates are symmetrically structured and have limiting holes thereon, the two sides of the plurality of second hinge seats are fixedly connected to limiting rods, and the ends of the plurality of limiting rods pass through the limiting holes and are slidably connected thereto.

[0008] Preferably, it further comprises a mounting plate, the top of which is fixedly connected to the two support plates respectively, and the top of the mounting plate is fixedly connected to a fixing frame.

[0009] Preferably, a first screw is rotatably connected to the inner wall of the fixing frame, an end of the first screw passes through the fixing frame and extends to the outside thereof, and an outer end of the first screw is fixedly connected to a rotating wheel.

[0010] Preferably, the inner wall of the fixing frame is rotatably connected to a connecting shaft, both ends of the connecting shaft respectively pass through the support plate and are rotatably connected thereto, the first screw and the outer circumferential wall of the connecting shaft are fixedly connected to first bevel gears, and the two first bevel gears are meshed with each other.

[0011] Preferably, both ends of the connecting shaft are fixedly connected with third bevel gears, the outer circumferential walls of the two bidirectional threaded rods are fixedly connected with second bevel gears, and the two third bevel gears are respectively engaged with the two second bevel gears.

[0012] The beneficial effects of the present invention are:

[0013] 1. The first screw is driven to rotate by rotating the rotating wheel, and the first screw drives the connecting shaft to rotate through the first bevel gear. The connecting shaft drives the two second bevel gears to rotate respectively through the two third bevel gears. The two second bevel gears drive the two-way threaded rods respectively, so that when the two second hinge seats move, they push the connecting arms to rotate around the rotating shaft as the center through the rotating arms, and the rollers are driven to rotate through the connecting arms. When the rollers slowly retract into the two support plates, the bottom of the support plates slowly drops until it contacts the ground. When the two-way threaded rods rotate in the opposite direction, the rotating arms push the rollers to rotate under the support plates, supporting the ground through the rollers, so that the support plates slowly rise. This design can facilitate the operator to retract and extend multiple rollers at the same time, improve operating efficiency, and enable the positioning plate to move stably.

[0014] 2. When the two bidirectional threaded rods rotate, the two second hinge seats can be moved respectively. The two second hinge seats slide along the inner wall of the limiting hole respectively through the limiting rods, thereby improving the stability of the second hinge seats during movement.
