[0027] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0028] According to the instruction manual Figure 1-5 It can be seen that when the utility model is used, an output end of the driving transmission structure drives the driving shaft 4 of the first conveyor belt 1 to rotate, thereby driving the first conveyor belt 1 to work. Figure 1 For example, the first conveyor belt 1 is driven to rotate counterclockwise, and the door and window panel 2 enters from the right side of the first conveyor belt 1. The second conveyor belt 7 is driven by the chain conveyor assembly 37 to rotate counterclockwise and at the same speed as the first conveyor belt 1. The chain conveyor assembly 37 adopts the existing technology; the driving transmission structure drives the first conveyor belt 1 to convey materials while the other output end drives the disc 12 to rotate. The disc 12 drives the upper end of the connecting rod 11 to rotate through the connecting column 13. The lower end of the connecting rod 11 is rotatably connected to the mounting seat 16 of the drilling machine 10, and the mounting seat 16 is vertically slidably connected to the mounting frame plate 15 through the fixing plate 28. Therefore, the rotation of the disc 12 can drive the connecting rod 11 to pull the mounting seat 16 and the drilling machine 10 to reciprocate vertically, and can convey the door and window panel 2 when moving downward, and the mounting seat 16 drives the fixing rod 17 and the clamping assembly 9 to clamp the door and window panel 2 when moving downward, and perform drilling operations at the same time to ensure the accuracy of drilling. In the utility model, the driving and transmitting structure can not only transmit the materials, but also drill the materials at the same time. Through the coordinated relationship between the two, equidistant continuous drilling operations can be performed. Compared with the existing technology, the work coordination and continuity are stronger, the drilling accuracy is high, and the method of equidistant transmission of door and window panels is more flexible and convenient than the workbench operation of the existing technology, and is convenient for personnel to operate.

[0029] The driving transmission structure includes a servo motor 24, a rotating shaft 27, a U-shaped fixed frame plate 26, an incomplete gear 25, a transmission gear 22 and a pulley assembly. When working, the servo motor 24 on the outer wall of the fixed frame plate 26 drives the rotating shaft 27 to rotate, thereby driving the disc 12 to rotate, and driving the drilling machine 10 to perform vertical reciprocating motion, thereby achieving the purpose of continuous drilling; at the same time, the rotation of the rotating shaft 27 drives the incomplete gear 25 to rotate, thereby driving the transmission gear 22 meshing with it to rotate and the connecting shaft 23 to rotate. The drive shafts 4 are connected by a pulley assembly, so the rotation of the connecting shaft 23 can drive the drive shaft 4 and the first conveyor belt 1 to work; of course, there is a time period when the incomplete gear 25 is missing teeth and cannot drive the transmission gear 22 to rotate, but this time period is exactly the time period when the clamping assembly 9 clamps and fixes the door and window panel 2 and drills it through the drilling machine 10, that is, at this time, the first conveyor belt 1 and the second conveyor belt 7 are not driven by external force, and the clamping assembly 9 fixes the door and window panel 2, so the drilling operation is more stable. The control of the spacing of the holes or the interval of each rotation is affected by the transmission speed of the door and window panel 2, the spacing of each transmission, and the cycle of the reciprocating motion of the drilling machine 10, and the direct factors are the speed of the servo motor 24, the model of the incomplete gear 25 and the transmission gear 22, and the model of the pulley assembly. However, those skilled in the art can easily obtain the relationship between them through experiments and calculations, and can achieve the purpose of continuous equidistant drilling of the utility model.

[0030] The pulley assembly includes a first pulley 19, a second pulley 21 and a V-belt 20. When working, the second pulley 21 on the connecting shaft 23 drives the second pulley 21 and the driving shaft 4 to rotate through the V-belt 20, and the transmission relationship is simple.

[0031] Among them, a support plate 14 is vertically arranged on the top of the mounting frame plate 15, and the rotating shaft 27 is rotatably connected to the support plate 14 through a bearing, which supports and limits the rotating shaft 27 and ensures the stability of the rotating shaft 27 in driving the disk 12 to rotate.

[0032] Among them, a slider 29 is provided on one side of the fixed plate 28 corresponding to the side wall of the mounting frame plate 15, and a slide groove 18 is vertically opened at the position of the side wall of the mounting frame plate 15 corresponding to the slider 29. When working, the drilling machine 10 makes the reciprocating motion more stable through the sliding connection relationship between the slider 29 and the slide groove 18.

[0033] Among them, a fixed beam 5 is arranged between a pair of base uprights 3, and the fixed beam 5 is located between the first conveyor belt 1 and the second conveyor belt 7. The upper surface height of the fixed beam 5 is flush with the upper surfaces of the first conveyor belt 1 and the second conveyor belt 7. When working, the fixed beam 5 provides support when the drilling machine 10 drills downward to ensure the stability of the drilling. The hole groove 6 on the surface of the fixed beam 5 ensures that the debris enters the hole groove 6 while the hole is drilled through to avoid damaging the working environment.

[0034] A limit plate 8 is arranged between the mounting frame plates 15 and at a position corresponding to the height of the upper surfaces of the first conveyor belt 1 and the second conveyor belt 7 to ensure the stability of the door and window panel 2 in the horizontal direction during transportation.

[0035] Among them, the clamping assembly 9 includes a horizontal plate 30, multiple compression springs 35, a pressure plate 32 and multiple limit rods 31. During operation, when the mounting seat 16 drives the fixing rod 17 to move downward, the pressure plate 32 first contacts the surface of the door and window panel 2. As it continues to move downward, the compression spring 35 between the horizontal plate 30 and the pressure plate 32 is compressed. During the reaction, the pressure plate 32 presses the door and window panel 2, and the limit rod 31 acts as a fiber. The clamping plate 34 prevents the limit rod 31 from slipping. As the pressure plate 32 presses the door and window panel 2, the drill bit of the drilling machine 10 starts drilling. The two work in coordination to ensure the stability and continuity of the work. In addition, a rubber pad 36 is provided at the bottom of the pressure plate 32 to prevent the pressure plate 32 from directly contacting the door and window panel 2 and scratching the surface.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
