DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the following will further illustrate the present application with reference to the drawings and examples. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the present application is not limited to the specific embodiments disclosed in the following description.

[0025] Example one

[0026] As shown in Figure 1 , Figure 3 and Figure 4 , the present application provides a top plate drawing device, which comprises a bottom plate 1, two support mechanisms 4 are fixedly connected on the top of the bottom plate 1, a drawing mechanism 2 is fixedly installed on the top of the support mechanism 4, and a positioning mechanism 3 is installed on the central top of the bottom plate 1;

[0027] The positioning mechanism 3 comprises a support plate 31 and an electric push rod 32, the bottom of the support plate 31 is fixedly connected with the bottom plate 1, a second sliding groove 312 is formed in the inner wall of the support plate 31, first sliding grooves 311 are formed on both sides of the second sliding groove 312, a lifting block 34 is slidably connected inside the second sliding groove 312, a linkage rod 35 is rotatably connected to one side of the lifting block 34, a second fixed rod 351 is rotatably connected to one end of the linkage rod 35, a sliding block 36 is fixedly connected to one end of the second fixed rod 351, a positioning rod 33 is fixedly connected to one end of the second fixed rod 351, the sliding block 36 is slidably connected with the first sliding groove 311, and the electric push rod 32 is fixedly connected with a connecting rod 321 at the top and the bottom, one ends of two connecting rods 321 are fixedly connected with the lifting block 34, and the other ends of the two connecting rods 321 are fixedly connected with the support plate 31.

[0028] The two support plates 31 are fixedly connected with side plates 37, the two side plates 37 are fixedly connected with guide blocks 39, the guide blocks 39 are slidably connected with second sliding rods 38 on the surfaces, and the second sliding rods 38 are fixedly connected with the positioning rods 33 at both ends.

[0029] Now, the specific settings and effects of the embodiment will be described. When performing the roof drawing operation, the roof needs to be placed on the surface of the moving groove 25 first. Next, by starting the electric push rod 32, the upper connecting rod 321 can be controlled to start moving upwards. As the connecting rod 321 rises, it will slide inside the second sliding groove 312, which will drive the lifting block 34 to rise together.

[0030] When the lifting block 34 moves upwards, it will drive the sliding block 36 to move through the two linkage rods 35. The connection between the linkage rod 35 and the sliding block 36 makes the sliding block 36 move horizontally along the direction of the first sliding groove 311 when the lifting block 34 moves. This design cleverly uses the principle of mechanical linkage, so that the roof can be accurately positioned and fixed.

[0031] As the sliding blocks 36 move in the first sliding groove 311, they will simultaneously drive the second fixed rod 351 and the positioning rod 33 to move. The role of these positioning rods 33 is to clamp the roof, ensuring that the roof can remain stable during the drawing operation and will not be skewed or moved.

[0032] Through the design of this mechanical structure, not only the efficiency and accuracy of the roof drawing operation are improved, but also the stability and safety of the equipment are enhanced.

[0033] Embodiment Two

[0034] As Figure 1 and Figure 2As shown, the drawing mechanism 2 includes a lower die 24 and a mounting plate 21, the bottom of the lower die 24 is fixedly connected with the support mechanism 4, the top of the lower die 24 is provided with a moving groove 25, the bottom of the mounting plate 21 is fixedly connected with two first fixed rods 23, and the bottom of the first fixed rod 23 is fixedly connected with the lower die 24. The top end of the positioning rod 33 penetrates through the lower die 24, and the positioning rod 33 is in sliding connection with the moving groove 25. The top of the mounting plate 21 is fixedly provided with a pneumatic push rod 22, and the lower side of the mounting plate 21 is provided with an upper die 26. The top of the upper die 26 is slidably connected with a first sliding rod 28 on both sides, and the top of the upper die 26 is fixedly connected with the bottom of the pneumatic push rod 22 in the center. The surface of the first sliding rod 28 is sleeved with a spring 27, and the two ends of the spring 27 are fixedly connected with the mounting plate 21 and the upper die 26 respectively.

[0035] The effect of the whole embodiment is that the pneumatic push rod 22 plays a key role when the drawing process is carried out. Once started, it will quickly push the upper die 26 to move downward. This action makes the upper die 26 gradually close to the moving groove 25, and prepares for the following drawing operation. The precise cooperation of the moving groove 25 and the upper die 26 is the key to ensure the quality of the roof drawing

[0036] The movement of the upper die 26 is not unlimited. It will slide on the surface of the first sliding rod 28. This design not only ensures the accuracy of the die combination of the upper die 26 and the moving groove 25, but also ensures the stability of the whole drawing process. At the same time, with the downward movement of the upper die 26, the spring 27 will be stretched by the first sliding rod 28. In this process, the spring 27 accumulates elastic potential energy, and prepares for the following reset action.

[0037] When the drawing operation is completed, the pneumatic push rod 22 will stop working, and at this time the elastic potential energy accumulated by the spring 27 begins to release. Under the action of the elastic force, the upper die 26 will quickly reset, preparing for the next drawing operation.

[0038] The use method and working principle of the device are as follows: when the roof drawing process is carried out, first, the roof is placed on the surface of the moving groove 25. Then, the pneumatic push rod 22 is started, pushing the upper die 26 to move downward, so that it gradually approaches the moving groove 25. Through the cooperation of the moving groove 25 and the upper die 26, the roof is drawn. In this process, the upper die 26 slides along the first sliding rod 28, ensuring accurate die combination with the moving groove 25. At the same time, the first sliding rod 28 stretches the spring 27, and uses the elasticity of the spring 27 to make the upper die 26 quickly reset after completing the die combination.

[0039] On the other hand, the electric push rod 32 is started, and the upper connecting rod 321 is driven to move upward, so that it slides in the second sliding groove 312. This action drives the lifting block 34 to rise, and further drives the two linkage rods 35 to move. The linkage rod 35 further pulls the sliding block 36 to move horizontally in the first sliding groove 311.

[0040] With the rising of the lifting block 34 and the pulling of the linkage rod 35, the two sliding blocks 36 move towards each other and converge. When the sliding blocks 36 slide in the first sliding groove 311, they simultaneously drive the second fixed rod 351 and the positioning rod 33 to move. Finally, the plurality of positioning rods 33 collectively clamp the top plate, complete the positioning thereof, and ensure that the top plate does not skew during the drawing process.

[0041] The above is only the preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technology content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made to the above embodiments without departing from the technical scheme of the present application, in accordance with the technical essence of the present application, still belong to the protection scope of the technical scheme of the present application.
