[0002] Before the linear guide is used, holes are often drilled on the linear guide through a drilling device, which facilitates the installation and fixation of the linear guide; the existing patent text with patent number CN210587244U discloses a linear rail moving drilling type linear rail drilling device, including a frame, a drilling mechanism, a plurality of drill bit assemblies distributed along the horizontal direction, and a linear rail fixing mechanism located below the drill bit assembly. The drill bit assembly includes a downward drill bit and a motor for driving the drill bit to rotate. The frame is provided with a crossbeam and a support plate located below the crossbeam. The drill bit assembly is connected to the crossbeam, and the linear rail fixing mechanism is connected to the support plate. The drilling mechanism includes two vertical slide rails distributed along the horizontal direction arranged on the frame, two slide grooves arranged at both ends of the support plate and slidably connected to the vertical slide rails in a one-to-one manner, and a support plate lifting mechanism for driving the support plate to rise and fall. The existing punching device punches holes from top to bottom, and the linear guide is directly fixed on the support plate through a fixed bracket. Since the support plate and the linear guide are placed horizontally, there will be a lot of waste chips on the support plate during the punching process of the linear guide; the waste chips are easy to remain on the linear guide, so the punching positioning of the linear guide will be deviated, and it is impossible to accurately punch holes according to actual requirements, and the punching effect is poor. Therefore, it is necessary to design an automatic punching device for linear guides to overcome the above difficulties. Summary of the invention

[0023] The specific operation process of this embodiment is as follows: the linear guide rail to be processed is placed on the material conveying assembly 11, so that the material conveying assembly 11 will drive the linear guide rail to approach the synchronous loading and unloading assembly 9, and then the synchronous loading and unloading assembly 9 will transport the linear guide rail to the product placement plate 2; since each of the clamping assemblies 93 has two mechanical clamping arms 931, the mechanical clamping arm 931 can clamp and take out the processed linear guide rail while transporting the linear guide rail; then the mechanical clamping arm 931 places the processed linear guide rail on the material support 13 first, and then the mechanical clamping arm 931 moves to the material conveying assembly 11 to grab the new linear guide rail. When the third motor 96 is working, it drives the sliding plate 95 to move along the third guide rail 94, and the sliding plate 95 is installed with a frame beam 92, and the frame beam 92 is installed with a clamping assembly 93, so that it is convenient to control the clamping assembly 93 to move between the material conveying assembly 11 and the product placement plate 2. When the fourth motor 932 is working, it drives the sliding frame 98 to move along the fourth guide rail 97, so that it is convenient to adjust the horizontal position of the clamping assembly 93, so as to adapt to the linear guide rails with different axial lengths. When the lifting motor 933 is working, it drives the mechanical clamping arm 931 to move up and down, so that it is convenient for the mechanical clamping arm 931 to clamp or put down the linear guide rail.

[0024] Before punching, the linear guide is fixed to the side of the product placement plate 2 by the clamping and positioning device 3, and then the punching assembly 5 can punch holes in the linear guide. The linear guide is first transported to the barb 341 of the second clamping member 34 by the synchronous loading and unloading assembly 9, and then the second cylinder 32 controls the second clamping member 34 to tighten upward, so that the linear guide will be fixed on the product placement plate 2; the clamping requirements during the punching process are relatively high, and the linear guide is fixed again here by the first clamping member 33. In the default state, the first clamping member 33 is pulled by the reset spring 310; when the linear guide needs to be clamped, the piston shaft of the first cylinder 31 extends, so that the first cylinder 31 will push the first clamping member 33 to rotate, and then the first clamping member 33 will abut against the surface of the linear guide; at this time, the reset spring 310 is in a stretched state. When the linear guide is punched, the piston shaft of the first cylinder 31 contracts, so that the first clamping member 33 will automatically loosen the linear guide, and then the second cylinder 32 controls the second clamping member 34 to move downward, thereby loosening the linear guide; finally, the synchronous loading and unloading assembly 9 can grab the processed linear guide.

The drill bit in the punching motor 53 will also automatically discharge water, so that the cooling effect is better. The surface of the linear guide rail is blown and dusted by the air blowing component 7 to prevent waste chips from remaining on the linear guide rail; the waste chips will automatically fall onto the air duct 8 of the bed body 1 during the cleaning process, and then the chip removal pipeline 10 is connected to the external fan, so that the fan will take away the waste chips in the air duct 8 after it works, and the dust removal effect is good and thorough.
