When different sizes of holes need to be drilled on the same part, it is necessary to frequently install and remove the drill bit from the drilling device, which is a cumbersome process and lacks flexibility and practicality.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please refer to Figures 1 to 6 Example 1: This utility model proposes a rapid drilling device for mechanical parts, comprising: a drive assembly 1 and a mounting assembly 2; the drive assembly 1 includes a connecting seat 101, a drive motor 102, a selection seat 103, and a positioning pin 104. The bottom of the connecting seat 101 is connected to the lifting arm of the drilling device, and the drive motor 102 is fixedly mounted on the side of the connecting seat 101. The selection seat 103 is rotatably connected to the side of the connecting seat 101, and the positioning pin 104 is inserted into the interior of the connecting seat 101 and the selection seat 103; the mounting assembly 2... Component 2 includes a drill bit chuck 201, a positioning frame 202, a clutch block 203, and a drive shaft 204. The drill bit chuck 201 is rotatably connected inside the selector seat 103, and the positioning frame 202 is inserted into the selector seat 103. The clutch block 203 is rotatably connected inside the positioning frame 202 and is inserted into the selector seat 103. The drive shaft 204 is rotatably connected inside the selector seat 103, and the drive shaft 204 and the shaft of the drive motor 102 are connected by a gear set.

[0023] The mounting assembly 2 has six sets, and the six sets of mounting assemblies 2 are arranged in a ring array inside the selection seat 103. In use, by installing drill bits of different specifications on the six drill bit chucks 201 for backup, it is possible to quickly drill holes of different specifications on the same part. There is no need to install or replace drill bits during the processing, which simplifies the operation process and improves the processing efficiency.

[0024] The connecting seat 101 has six positioning magnetic blocks 1011 inside. Five of the positioning magnetic blocks 1011 are arranged in a ring array on the inner ring of the connecting seat 101, and the other positioning magnetic block 1011 is installed on the outer ring of the connecting seat 101. The positioning magnetic block 1011 installed on the outer ring of the connecting seat 101 is located directly below the connecting seat 101. The positioning frame 202 has an adsorption magnetic block 2021 on its outside, and the adsorption magnetic block 2021 and the positioning magnetic block 1011 can attract each other. The clutch block 203 has a synchronization groove 2031 inside, and the drive shaft 2 The shaft cross-section of drive shaft 204 is a regular polygon. The polygonal section of drive shaft 204 is inserted into the synchronous groove 2031. The bottom of the rotating shaft of drill bit chuck 201 is equipped with a drilling gear 2011, and the clutch block 203 has a drilling tooth groove 2032 inside. When the magnetic adsorption block 2021 and the outer ring positioning magnetic block 1011 are attracted, the drilling gear 2011 is inserted into the drilling tooth groove 2032. When the magnetic adsorption block 2021 and the inner ring positioning magnetic block 1011 are attracted, the drilling gear 2011 and the drilling tooth groove 2032 are separated. In use, only... The downward-facing mounting component 2 can be connected to the drive motor 102 to drive the drilling action, while the other mounting components 2 remain stationary, effectively protecting the drill bit and the operator. The magnetic block 2021 of the downward-facing mounting component 2 can be attracted to the positioning magnetic block 1011 on the outer ring, so that the drilling gear 2011 of this mounting component 2 is inserted into the drilling tooth groove 2032. At this time, the drive motor 102 can drive the drive shaft 204 to rotate through the gear set. When the drive shaft 204 rotates, it can drive the clutch block 203 to rotate through the synchronous groove 2031. When the clutch 203 rotates, the drilling tooth groove 2032 can drive the drill bit chuck 201 and the drill bit to rotate through the drilling gear 2011, thereby cooperating with the lifting action of the lifting arm to realize the drilling of mechanical parts. Although the other drive shafts 204 can also rotate synchronously, the magnetic blocks 2021 of the other mounting components 2 are attracted to each other with the positioning magnetic blocks 1011 of the inner ring. Therefore, the drilling gears 2011 and the drilling tooth groove 2032 of the other mounting components 2 are in a state of separation from each other, so the other drill bit chuck 201 will not rotate, and the operation is stable.

[0025] The selector seat 103 has six positioning holes 1031 inside, and the connecting seat 101 has a reference hole 1012 inside. The rod of the positioning pin 104 passes through the positioning holes 1031 and is inserted into the reference hole 1012. In use, the positioning pin 104 is inserted into the reference hole 1012 after passing through the appropriate positioning holes 1031, so that the use angle of the selector seat 103 and the selected mounting component 2 can be positioned. When it is necessary to switch the use of the mounting component 2, simply pull out the positioning pin 104, and the selector seat 103 can rotate freely. After rotating the selector seat 103 to the appropriate angle, the positioning pin 104 can be reinserted to position the use angle of the selector seat 103. The mounting component 2 used downwards will also change after the use angle of the selector seat 103 is changed, thus realizing the function of switching the drill bit. The operation is convenient and the switching is quick.

[0026] The working principle of this embodiment is as follows: By installing drill bits of different specifications on six drill bit chucks 201 for backup, it is possible to quickly drill holes of different specifications on the same part. No drill bit installation or replacement is required during processing. The positioning pin 104 passes through the appropriate positioning hole 1031 and is inserted into the reference hole 1012 to position the operating angle of the selection seat 103 and the selected mounting component 2. When it is necessary to switch the mounting component 2, simply pull out the positioning pin 104, allowing the selection seat 103 to rotate freely. After rotating the selection seat 103 to the appropriate angle, the positioning pin 104 is reinserted to position the operating angle of the selection seat 103. Furthermore, changing the operating angle of the selection seat 103 also changes the downward-facing mounting component 2, thus realizing the function of switching drill bits. Only the downward-facing mounting component 2 can connect to the drive motor 102 to drive the drilling action; the other mounting components 2 remain stationary, effectively protecting the drill bit. When the head and workers are using the downward-facing mounting assembly 2, the magnetic block 2021 of the mounting assembly 2 can attract each other with the positioning magnetic block 1011 of the outer ring, so that the drilling gear 2011 of the mounting assembly 2 can be inserted into the drilling tooth groove 2032. At this time, the drive motor 102 can drive the drive shaft 204 to rotate through the gear set. When the drive shaft 204 rotates, it can drive the clutch block 203 to rotate through the synchronous groove 2031. When the clutch block 203 rotates, the drilling tooth groove 2032 can be driven by the drilling... The bore gear 2011 drives the drill chuck 201 and the drill bit to rotate, thereby coordinating with the lifting action of the lifting arm to realize the drilling of mechanical parts. Although the other drive shafts 204 can also rotate synchronously, the magnetic blocks 2021 of the other mounting components 2 are attracted to the positioning magnetic blocks 1011 of the inner ring. Therefore, the drilling gears 2011 and the drilling tooth grooves 2032 of the other mounting components 2 are in a state of separation, and thus the other drill chucks 201 will not rotate.
