[0001] This utility model relates to the technical field of sawing devices for flame-retardant plates in special vehicle bodies, specifically a sawing device for flame-retardant plates in special vehicle bodies with a protective mechanism. Background Technology

[0002] The edge-cutting device for flame-retardant panels used in special vehicle bodies is a piece of equipment used for edge cutting of flame-retardant panels. However, existing flame-retardant panel cutting equipment has some shortcomings, such as:

[0003] The fireproof board edge sawing device described in application number CN202322361441.1 has no protective structure. In actual use, if non-operators get too close, accidents can easily occur due to incorrect operation. Utility Model Content

[0004] The purpose of this utility model is to provide a special vehicle body flame-retardant plate sawing device with a protective mechanism, so as to solve the problem mentioned in the background art that the existing equipment on the market does not have a protective structure. In actual use, if non-operators get too close, accidents can easily occur due to incorrect operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special vehicle body flame-retardant plate sawing device with a protective mechanism, comprising a support frame, a first connecting rod, a limiting block, a support platform and a traction disc;

[0006] The side of the support frame is equipped with a cutting head;

[0007] The cutting head is provided with a cutting frame, a motor and a lead screw on its side. A limit block and a spring are provided below the center line of the support frame. A support platform is installed above the support frame. A protective ring, a first connecting rod, a second connecting rod and a traction disc are provided on the side of the support frame. A pressure plate is provided above the protective ring.

[0008] As a preferred technical solution of this utility model, the limiting block is slidably connected to the center line of the bottom of the support frame, the bottom of the support frame is fixedly connected to one end of the spring, the other end of the spring is fixedly connected to the limiting block, and a U-shaped groove is opened on the side of the limiting block.

[0009] Using the above technical solution, the limiting block is slidably connected to the center line of the bottom of the support frame and connected to the spring. This structural design allows the limiting block to move flexibly. When the support frame is subjected to external impact or vibration during operation, the spring can play a buffering role, preventing the limiting block from damaging the support frame due to rigid connection. At the same time, the U-shaped groove on the side of the limiting block facilitates cooperation with other components and enhances the overall stability of the device.

[0010] As a preferred technical solution of this utility model, three support legs are evenly fixed at the bottom of the support frame, and the bottom support part of the support frame has a triangular structure;

[0011] By adopting the above technical solution, three support legs are evenly fixed at the bottom of the support frame, and the bottom support part is in the form of a triangular structure. Triangles have stability, which, compared with other support structures, allows the support frame to be placed more stably on the working surface, reducing the risk of shaking or tipping over during operation and ensuring the smooth progress of the sawing work.

[0012] As a preferred technical solution of this utility model, the cutting frame is slidably connected to the side of the support frame, and the support frame has two parts: an upper and a lower part. The lower part of the support frame is a block structure, and the side of the support frame is fixed with a trapezoidal tenon strip. The tenon strip on the side of the support frame matches the slot of the support frame.

[0013] With the above technical solution, the cutting frame is slidably connected to the side of the support frame. The tenon and slotted structure of the support frame are matched, which not only facilitates the installation and disassembly of the cutting frame, but also makes it easy to maintain and replace the cutting frame. It can also provide a stable guide for the cutting frame during the cutting process, ensuring that the cutting head moves along the predetermined direction and improving the accuracy of the sawing edge.

[0014] As a preferred embodiment of this utility model, the upper part of the support frame is rotatably connected to the lead screw, the left side of the lead screw is fixedly connected to the motor output shaft, and the side of the lead screw is threadedly connected to the cutting head;

[0015] Using the above technical solution, the lead screw is rotatably connected to the support frame, the left side is fixed to the motor output shaft, and the lead screw is threadedly connected to the cutting head. This transmission method can accurately convert the rotational motion of the motor into the linear motion of the cutting head. By controlling the speed and direction of the motor, the moving speed and position of the cutting head can be precisely controlled, so as to achieve precise sawing of the flame-retardant board.

[0016] As a preferred technical solution of this utility model, the traction disc is rotatably connected to the center line position above the support frame, and an L-shaped remote rod is provided at the center position of the traction disc, and the first connecting rod is rotatably connected above the center point of the traction disc, and the second connecting rod is rotatably connected below the center point of the traction disc;

[0017] Using the above technical solution, the traction disc is rotatably connected to the center line above the support frame and is connected to the first and second connecting rods through a special structure. This design enables the traction disc to stably drive the first and second connecting rods when rotating, thereby realizing smooth lifting and lowering control of the protective ring and pressure plate, which facilitates the pressing and loosening of the plate.

[0018] As a preferred technical solution of this utility model, a pair of protective rings are rotatably connected to the side of the pressure plate. There are four protective rings in total, which are distributed in opposite directions. The protective rings are C-shaped. The first connecting rod and the second connecting rod are rotatably connected between the protective rings. The bearing platform is rotatably connected above the bearing frame. Both the bearing platform and the lead screw are provided with scale markings.

[0019] Using the above technical solution, four opposing C-shaped protective rings are rotatably connected to the side of the pressure plate, and the protective rings are connected to each other through the first and second connecting rods. This structure can not only effectively transmit the pressure of the pressure plate evenly to the board, ensuring the stability of the board when sawing the edge; but also the protective rings can flexibly adjust their position with the movement of the pressure plate and connecting rods, forming good protection for the cutting head and preventing cutting debris from flying and injuring people.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. Enhanced safety protection: The ring-shaped protective ring effectively isolates the area where people can approach; at the same time, the protective ring physically isolates the cutting head, preventing accidental contact with the cutting head from causing injury.

[0022] 2. Excellent board fixing effect: The rubber anti-slip pad on the bottom of the pressure plate and the reasonable size design keep the flame-retardant board stable during the cutting process, effectively preventing the board from shifting and ensuring the cutting quality.

[0023] 3. Significantly improved cutting accuracy: The scale markings on the support table and lead screw provide operators with accurate cutting references, facilitating quick positioning and control of the cutting depth, meeting the high-precision edge sawing requirements of flame-retardant plates for special vehicle bodies, and reducing material waste caused by cutting errors.

When the support frame 1 is subjected to external impact or vibration during operation, the spring 11 can act as a buffer, preventing damage to the support frame 1 due to the rigid connection of the limiting block 3. Simultaneously, the U-shaped groove on the side of the limiting block 3 facilitates cooperation with other components, enhancing the overall stability of the device. A limiting block 3 and a spring 11 are located below the center line of the support frame 1. Three springs are evenly fixed at the bottom of the support frame 1. The support frame 1 has three supporting legs, and the bottom support part is triangular. The bottom support part is triangular, which provides stability. Compared with other support structures, it can make the support frame 1 more stable on the working surface, reducing the risk of shaking or tipping during operation and ensuring the smooth progress of the sawing work. The support frame 1 is equipped with a support platform 4 on top of the support frame 1. The cutting frame 8 is slidably connected to the side of the support frame 1. The support frame 1 has two parts: the lower part is a block structure, and the side of the support frame 1 is fixed with trapezoidal tenons. The tenons on the side of the support frame 1 match the slot of the support frame 1. The cutting frame 8 is slidably connected to the side of the support frame 1. The tenons and slotted structure of the support frame 1 are compatible, which facilitates the installation and disassembly of the cutting frame 8 and makes it easy to maintain and replace the cutting frame 8.It can also provide stable guidance for the cutting frame 8 during the cutting process, ensuring that the cutting head 9 moves along the predetermined direction and improving the accuracy of the sawing edge. The side of the support frame 1 is provided with a protective ring 7, a first connecting rod 2, a second connecting rod 5 and a traction disc 13.

Adjust the position of the plate according to the support platform 4 so that the edge to be cut is aligned with the cutting head 9. Then, rotate the traction disc 13. The traction disc 13 drives the protective ring 7 and the pressure plate 6 to descend through the first connecting rod 2 and the second connecting rod 5. The rubber anti-slip pad on the bottom of the pressure plate 6 presses the flame-retardant plate firmly, fixing the plate securely. Start the motor 10. The output shaft of the motor 10 drives the lead screw 12 to rotate. The lead screw 12 is threadedly connected to the cutting head 9, so that the cutting head 9 moves along the guide rail on the side of the support frame 1 to perform the sawing operation on the flame-retardant plate. During the cutting process, the protective ring 7 is in a ring shape, which can effectively isolate the area where people approach, ensuring the safety of the operator. After the cutting is completed, rotate the traction disc 13 in the opposite direction to raise the pressure plate 6 and the protective ring 7, and take out the cut flame-retardant plate.
