At the same time, the second clamping plate 44 can guide the twist drill 12 during processing, effectively reducing the hole position offset or surface damage of parts caused by processing. The adjustment component 3 for adjusting the drilling height of the bell-shaped cover component 14 is connected to the clamping component 4. The adjustment component 3 can perform corresponding height adjustment according to the height of the side opening of the bell-shaped cover component 14, which increases the practicality of the equipment. The second motor 25 for driving the drive disk 22 to rotate is fixedly connected to the lower side of the drilling machine base 11, and the drive shaft of the second motor 25 is fixedly connected to the drive disk 22.

[0026] like Figure 1 to Figure 4 As shown, the adjustment component 3 includes a support frame 31, which is fixedly connected to the drilling machine base 11, and a plurality of sliding columns 33 are fixedly connected between the upper side of the support frame 31 and the drilling machine base 11. The adjustment plate 34 is sleeved on the sliding column 33, and the adjusting screw 35 is rotatably connected to the adjusting plate 34. The two ends of the adjusting screw 35 are rotatably connected to the drilling machine base 11 and the support frame 31 respectively. The first motor 32 is fixedly connected to the upper side of the support frame 31, and the driving shaft of the first motor 32 is fixedly connected to the adjusting screw 35. The sliding plate 36 is fixedly connected to the adjusting plate 34.

[0027] like Figure 2 to Figure 5 As shown, the clamping assembly 4 includes a first clamping plate 41, a limiting chassis 46 and two limiting columns 43. The limiting chassis 46 is slidably abutted against the two limiting blocks 37. The limiting chassis 46 is positioned and clamped with the bottom surface of the bell-shaped cover component 14. A reset assembly for resetting the limiting chassis 46 moved by the driving disk 22 is connected to one side of the limiting chassis 46. The second clamping plate 44 is slidably connected to the two limiting columns 43. The three separate components of the first clamping plate 41, the second clamping plate 44 and the limiting chassis 46 are used to jointly complete the positioning and clamping of the bell-shaped cover component 14, so that the bell-shaped cover component 14 is fixed. The disassembly and assembly becomes convenient, and the processing efficiency is increased. Each buffer spring 45 is sleeved on each limit column 43, and the two ends of the buffer spring 45 are respectively abutted against the second clamping plate 44 and the side wall of the drilling rig 13 shell.

Each limit ring 42 is fixedly connected to the end of each limit column 43 away from the drilling rig 13, and the first clamping plate 41 is fixedly connected to the first linkage plate 24.

[0028] like Figure 2 and Figure 3 As shown, the first retaining plate 41 and the second retaining plate 44 have opposite sides formed with groove surfaces identical to the busbars of the bell-shaped cover component 14. When the first retaining plate 41 and the second retaining plate 44 clamp the bell-shaped cover component 14 against each other, they are completely fitted with the outer shape of the bell-shaped cover component 14, and the limiting function of the limiting chassis 46 is used to limit the five degrees of freedom of the bell-shaped cover component 14, so that the bell-shaped cover component 14 will not deviate at will.

[0029] like Figure 1 and Figure 5 As shown, the reset assembly includes a reset plate 47 and a second linkage plate 49, the reset plate 47 is fixedly connected to the sliding plate 36, the reset column 48 is fixedly connected to the side of the reset plate 47 away from the limiting chassis 46, the second linkage plate 49 is slidably connected to a plurality of reset columns 48, and one end of the second linkage plate 49 away from the reset plate 47 is fixedly connected to the side of the limiting chassis 46, each reset spring 491 is sleeved on each reset column 48, and the two ends of the reset spring 491 are respectively abutted against the reset plate 47 and the second linkage plate 49, and the reset spring 491 can make the driving disk 22 rotate, and then the limiting chassis 46 for positioning the bell-shaped cover component 14 can be reset along with the first positioning plate 41, so that the bell-shaped cover component 14 that has been processed can be removed and the next bell-shaped cover component 14 that needs to be processed can be positioned.

[0030] like Figure 2-3 and Figure 7As shown, the docking hole 441 is opened on the second clamping plate 44, and the aperture of the second clamping plate 44 is larger than the diameter of the twist drill 12. The docking hole 441 guides the twist drill 12 to drill the bell-shaped cover component 14 to prevent the twist drill 12 from deviating, thereby ensuring the service life of the twist drill 12.

[0031] like Figure 1 and Figure 5 As shown, the discharge hole 461 is opened on the limiting chassis 46, so that the chips generated after the bell-shaped cover component 14 is drilled can fall to the lower side from the discharge hole 461, preventing the chips from accumulating on the limiting chassis 46, thereby ensuring the positioning effect of the limiting chassis 46 on the bottom of the bell-shaped cover component 14.

[0032] The working principle of this embodiment is:

[0033] By controlling the speed of the second motor 25, the speed of the drive disk 22 can be accurately controlled, that is, the cutting amount of the twist drill 12 can be controlled to prevent the twist drill 12 from being damaged by excessive back cutting. Then, the rotation of the drive disk 22 drives the drive plate 23 to move back and forth. When the end of the drive plate 23 hinged to the drive disk 22 moves to the farthest position from the drilling machine 13, it stops, and the bell-shaped cover component 14 to be processed is placed on the limiting chassis 46 according to the bottom features, and the first clamping plate 41 is abutted against the outer wall of the bell-shaped cover component 14, and then the drive disk 22 is driven continuously, and the first clamping plate 41 is moved to the outer wall of the bell-shaped cover component 14. The plate 41 exerts a force on the side of the bell-shaped cover component 14, and moves the limiting chassis 46 together. During the movement, after the bell-shaped cover component 14 abuts against the second locking plate 44, a force is exerted on the second locking plate 44, so that the rotating twist drill 12 performs a hole drilling operation on the side of the bell-shaped cover component 14 along the docking hole 441. After the hole drilling is completed, the driving disk 22 will reset the driving plate 23. Under the action of the reset component, the limiting chassis 46 will reset the bell-shaped cover component 14 together with the first locking plate 41, so that the operator can take and place the processed bell-shaped cover component 14 conveniently.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
