[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 2 As shown, a drilling tool for processing a transmission shaft includes a bottom plate 1, a base 2 is installed on the top of the bottom plate 1, a drilling mechanism is installed on the top of one end of the base 2, and the drilling mechanism includes a fixing frame 3, a cylinder 4 is installed inside the fixing frame 3, a motor 5 is installed on the movable end of the cylinder 4 through a horizontal plate, and a drill bit 6 is installed on the output end of the motor 5.

[0021] The motor 5 drives the drill bit 6 to rotate, and the drill bit 6 is driven to move up and down by the extension and contraction of the cylinder 4, so as to drill a hole in the transmission shaft.

[0022] like Figure 1 and Figure 3 As shown, the interior of the base 2 is a hollow structure, and a fixed seat 7 and a movable seat 8 for positioning the transmission shaft are installed on the top. The rear ends of the fixed seat 7 and the movable seat 8 are both installed with clamping components, and a translation component for driving the movable seat 8 to move is installed inside the base 2.

[0023] The clamping assembly includes a mounting frame 9, an ear plate 10 is fixed to the bottom of the mounting frame 9, a cylinder 2 11 is installed on the inner top, and an upper pressure seat 12 is installed on the output end of the cylinder 2 11. The upper pressure seats 12 in the two clamping assemblies are respectively located directly above the fixed seat 7 and the movable seat 8. The top surfaces of the fixed seat 7 and the movable seat 8, as well as the bottom surface of the upper pressure seat 12 are all provided with V-shaped grooves, and both sides of the V-shaped grooves are provided with anti-slip grooves.

[0024] A slide groove is provided on the top surface of the base 2 between the through groove 1 and the fixed seat 7. The translation assembly includes a vertical plate 13 and a partition 14 installed on the top of the base 2. The vertical plate 13 and the partition 14 are located at both ends of the slide groove, and a screw rod 15 is rotatably installed between the vertical plate 13 and the partition 14. A motor 2 16 for driving the screw rod 15 to rotate is installed on the vertical plate 13. The outer side of the screw rod 15 is threadedly connected to a driving block 17. The top of the driving block 17 passes through the slide groove and is connected to the movable seat 8.

[0025] Place the drive shaft on top of the fixed seat 7 and the movable seat 8, extend the cylinder 2 11 to make the upper pressure seat 12 move downward, and cooperate with the fixed seat 7 and the movable seat 8 to achieve the compression and fixation of the drive shaft. Both sides of the V-groove are provided with anti-slip grooves to prevent the drive shaft from rotating during drilling.

[0026] The second motor 16 drives the screw rod 15 to rotate, so that the driving block 17 drives the movable seat 8 to move, thereby adjusting the position of the movable seat 8, and then adjusting the distance between the movable seat 8 and the drilling mechanism according to the different lengths of the transmission shaft.

[0027] like Figure 4 As shown, a through slot 1 is provided on the top surface of the base 2 below the drilling mechanism, and support columns 18 are installed on the tops of both ends of the through slot 1. A support seat 19 is installed on the top of the support column 18. The size of the support seat 19 is smaller than that of the through slot 1, and a through slot 2 is provided in the middle thereof. Positioning frames 20 are symmetrically fixed at both ends, and a cylinder 3 21 is installed through the positioning frame 20, and a pressure plate 22 is installed on the movable end of the cylinder 3 21.

[0028] The part of the drive shaft that needs to be drilled is placed on the top of the support seat 19 and above the through slot 2. The cylinder 3 21 is extended to move the pressure plate 22 downward, which can tighten and fix both sides of the drilling part, thereby improving the stability of the drive shaft during drilling.

[0029] A collection frame 23 is placed below the first through slot inside the base 2 . The size of the collection frame 23 is larger than that of the first through slot. An operation port is provided on the front end of the base 2 . Limiting bars 24 are fixed to both sides of the collection frame 23 inside the base 2 .

[0030] The debris generated during drilling falls into the collection frame 23 through the through slot 1, thereby realizing automatic collection of the debris and preventing the debris from being scattered everywhere.

[0031] In practice, the position of movable seat 8 is adjusted according to the length of the drive shaft, allowing at least one clamping assembly to compress and secure the drive shaft. Cylinder 2 (11) extends, causing upper pressure seat 12 to move downward. This, in conjunction with fixed seat 7 and movable seat 8, compresses and secures the drive shaft. Cylinder 3 (21) extends, causing pressure plate 22 to move downward, compressing both sides of the drilling area. Motor 1 (5) rotates drill bit 6, which, through the expansion and contraction of cylinder 1 (4), moves it up and down, drilling the drive shaft. Debris generated during drilling falls through slot 1 into collection frame 23, automatically collecting the debris.

[0032] The undisclosed parts in the present invention are all prior art, and their specific structures and working principles are not described in detail here.
