Description

Technical Field

[0001] This utility model relates to the technical field of polyurethane board production equipment, and in particular to a polyurethane board production positioning device. Background Technology

[0002] Polyurethane boards are panels made from polyurethane using specific processes. They have a low thermal conductivity, significantly lower than traditional insulation materials such as polystyrene boards and rock wool boards. This gives polyurethane boards significant advantages in building insulation, cold storage insulation, and other fields, effectively reducing heat transfer and energy consumption. Polyurethane boards are lightweight, have good dimensional stability, and are easy to cut, install, and splice. They can be installed using various methods such as pasting, nailing, and splicing, greatly improving construction efficiency and shortening the construction cycle.

[0003] A polyurethane board production positioning device, with authorized publication number CN222199289U, includes a worktable and a laser cutting machine for cutting operations. The worktable is equipped with a movable adjusting rod, and the laser cutting machine is connected to the adjusting rod via an electric push rod. Auxiliary blocks are fixedly connected to both the front and rear sides of the worktable, and two U-shaped connecting rods capable of synchronous movement are mounted on the auxiliary blocks. By incorporating a connecting plate, fixing blocks, and arc-shaped gaskets controlled by an electric telescopic rod, the device achieves the effect of fixing the polyurethane board while preventing scratches and damage and buffering impact forces. The electric telescopic rod controls the connecting plate to move up and down within the U-shaped connecting rods, and the fixing blocks on the lower wall of the connecting plate fix the polyurethane board. The arc-shaped gaskets at both ends of the fixing blocks are smooth-surfaced arc-shaped elastic blocks that first contact the polyurethane board during the fixing process, effectively preventing scratches and damage.

[0004] The drawback of the aforementioned technologies is that polyurethane boards are subject to mechanical vibration on the production line. If they are only fixed vertically, they will slide horizontally. The positional changes caused by external interference will increase the scrap rate. Therefore, this utility model provides a polyurethane board production positioning device. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] refer to Figure 1-4 The polyurethane board production positioning device shown includes a workbench 1, which is hollow. This hollow design provides installation and operating space for the internal positioning components, facilitating their layout and operation. The workbench 1 houses the positioning components, including a first connecting hole 8 opened on one side of the workbench 1. A rotating rod 10 is rotatably connected inside the first connecting hole 8, providing a support point for the rotation of the rotating rod 10. This allows the rotating rod 10 to rotate flexibly within the hole. The rotating rod 10 transmits power and changes the direction of force. Rotation of the rod drives connected components to move, thereby achieving the subsequent positioning function.

[0025] A deflection plate 3 is fixedly connected to the side wall of the rotating rod 10. A first positioning block 4 is fixedly connected to one end of the deflection plate 3. The first positioning block 4 is located outside the worktable 1. A transfer ball 17 is located at the other end of the deflection plate 3. The transfer ball 17 is located inside the worktable 1. The deflection plate 3 can deflect as the rotating rod 10 rotates, thereby changing the position of the first positioning block 4 and realizing the horizontal positioning adjustment of the polyurethane board. The first positioning block 4 is used to directly contact and position the polyurethane board. By changing its own position, it can fix polyurethane boards of different sizes and positions, improving the positioning accuracy and flexibility. The transfer ball 17 plays the role of transmitting power, which can transmit the externally applied power to the deflection plate 3, so that the deflection plate 3 can rotate smoothly, thereby driving the first positioning block 4 to move and realize the positioning function.

[0026] A spring 11 is fixedly connected to the side wall of the deflection plate 3. The spring 11 is elastic, and the other end of the spring 11 is fixedly connected to the inner top wall of the worktable 1. When the deflection plate 3 rotates, the spring 11 will be stretched or compressed, playing a role in buffering and resetting. When the external force disappears, the spring 11 can make the deflection plate 3 return to its initial position, ensuring the stability and repeatability of positioning. The spring 11 is provided with a fixed support point, enabling it to perform its buffering and resetting functions normally.

[0027] A hydraulic push rod 15 is fixedly connected to the inner bottom wall of the workbench 1. A push plate 16 is fixedly connected to the output end of the hydraulic push rod 15, and a fixed block 14 is fixedly connected to the top of the push plate 16. The hydraulic push rod 15 can generate thrust through the hydraulic system to provide power to the push plate 16. The magnitude and direction of the output thrust can be precisely controlled according to actual needs. The push plate 16 is used to receive the thrust output by the hydraulic push rod 15 and transmit this force to the fixed block 14, thereby pushing the fixed block 14 to move.

[0028] One end of the fixed block 14 is rotatably connected to a movable plate 13 via a pin. The movable plate 13 can rotate around the connection point with the fixed block 14 and can change its angle during movement to adapt to different positioning requirements. A limiting groove 12 is formed inside the movable plate 13. The limiting groove 12 is divided into two sections: the upper section is a vertical groove and the lower section is an inclined groove. A second connecting hole 7 is formed inside the opening on the other side of the worktable 1. A linkage rod 9 is fixedly connected inside the second connecting hole 7. One end of the linkage rod 9 is fixedly connected to the worktable 1, and the other end slides in the limiting groove 12.

[0029] The fixing block 14 is used to fix and connect the moving plate 13, enabling the moving plate 13 to move with the push plate 16 and providing a support point for the rotation of the moving plate 13. The limiting groove 12 is used to limit the linkage rod 9, so that the linkage rod 9 can only slide inside the limiting groove 12, thereby restricting the movement trajectory of the moving plate 13 and ensuring that the moving plate 13 moves in a predetermined direction and manner. The second connecting hole 7 provides a mounting position for the linkage rod 9, allowing it to be fixed on the worktable 1, and provides the necessary space for the linkage rod 9 to slide in the limiting groove 12. The linkage rod 9 plays a connecting and transmitting role. Through its cooperation with the limiting groove 12, the linkage rod 9 slides inside the limiting groove 12, thereby constraining and guiding the movement of the moving plate 13 and ensuring that the moving plate 13 can accurately reach the predetermined position.

[0030] A connecting plate 6 is fixedly connected to one end of the movable plate 13 outside the worktable 1. The connecting plate 6 is used to connect the movable plate 13 and the second positioning block 5. The second positioning block 5 can move with the movable plate 13. The second positioning block 5 is fixedly connected to the side wall of the connecting plate 6. The second positioning block 5 is located outside the worktable 1. The second positioning block 5 is used to cooperate with the first positioning block 4 to perform bidirectional positioning of the polyurethane board in the horizontal direction, thereby improving the accuracy and stability of positioning.

[0031] A limiting frame 2 is fixedly connected to the top of the workbench 1. The limiting frame 2 is used to initially limit the polyurethane board placed on the workbench 1, determine the placement range of the polyurethane board, prevent the polyurethane board from moving randomly on the workbench 1, and provide a basis for subsequent precise positioning.

[0032] The working principle of this device is as follows: When using this device, the operator first starts the hydraulic push rod 15, which raises the position of the push plate 16. The push plate 16 raises the position of the moving plate 13 through the fixed block 14. Due to the linkage rod 9 in the limiting groove 12, the moving plate 13 will first raise the second positioning block 5 and then deflect at a certain angle. As the hydraulic push rod 15 continues to extend, it will abut against the transfer ball 17, causing the spring 11 to compress. The deflection plate 3 will deflect around the rotating rod 10 as the axis. At this time, the polyurethane plate is placed in the limiting frame 2, causing the hydraulic push rod 15 to retract, thereby achieving horizontal and vertical positioning of the polyurethane plate.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
