[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Please see attached Figure 1-8 , an embodiment of the present invention: a CNC drilling device, comprising a main frame 1, a first fixed drilling mechanism 2 is arranged on one side of the main frame, a mobile drilling mechanism 3 is arranged on the other side, an upper vertical drilling mechanism 4 is arranged on the top, and a lower vertical drilling mechanism 5 is arranged on the bottom, and a feeding mechanism 6 is fixedly connected to the first fixed drilling mechanism 2 and the mobile drilling mechanism 3. The main frame 1 is electrically connected to a main power cabinet 7 on the outside, and the main power cabinet 7 is used to control the power supply of the first fixed drilling mechanism 2, the mobile drilling mechanism 3, the upper vertical drilling mechanism 4, the lower vertical drilling mechanism 5 and other operating components, so that each component can cooperate and operate according to the processing requirements.

[0041] Specifically, the first fixed drilling mechanism 2 includes a horizontal drill body 201, on which a vertical adjustment mechanism, a horizontal adjustment mechanism, and a drill group 203 are provided. The vertical adjustment mechanism and the horizontal drill body 201 are slidably connected through a guide rail slider device, the vertical adjustment mechanism and the horizontal adjustment mechanism are fixedly connected through screws, the drill group 203 is fixedly connected with the horizontal adjustment mechanism, and the drill group 203 includes a drill group drive motor 20301 and a plurality of drill bits 20303. The drill group 203 adjusts the drill bit 20303 to an appropriate position through the cooperation of the vertical adjustment mechanism and the horizontal adjustment mechanism, and can keep the position relatively fixed after positioning, thereby ensuring the drilling quality of the plate processing and improving the assembly accuracy of the plate.

[0042] The vertical adjustment device includes a horizontal slider mounting plate 205 and a horizontal drill mounting plate 207. The horizontal drill mounting plate 207 is provided with a slider. The horizontal drill main body 201 is provided with a fixed drilling first servo motor 206 and a guide rail. The horizontal drill mounting plate 207 and the horizontal drill main body 201 are connected to each other in a stable sliding manner through the guide rail slider. The fixed drilling first servo motor 206 is connected to the horizontal drill mounting plate 207 through a ball screw. One end of the horizontal slider mounting plate 205 is fixedly connected to the horizontal drill mounting plate 207, and the other end is fixedly connected to the horizontal adjustment mechanism. When the fixed drilling first servo motor 206 rotates, the horizontal drill mounting plate 207 is driven to move up and down through the ball screw. The horizontal drill mounting plate 207 is fixedly connected to the horizontal adjustment device through the horizontal slider mounting plate 205. Therefore, the horizontal adjustment mechanism can be controlled by the fixed drilling first servo motor 206 as a whole.

[0043] The horizontal adjustment mechanism includes a horizontal seat 202 and a horizontal drilling slide 208. The horizontal seat 202 is fixedly connected to the vertical adjustment mechanism. The horizontal seat 202 is provided with a slider. The horizontal drilling slide 208 is provided with a guide rail. The horizontal seat 202 is slidably connected to the horizontal drilling slide 208. The horizontal seat 202 is provided with a fixed drilling second servo motor 209. The fixed drilling second servo motor 209 is connected to the horizontal drilling slide 208 through a nut seat 20801. When the fixed drilling second servo motor 209 rotates forward, the horizontal drilling slide 208 slides relative to the slider of the horizontal seat 202 through the guide rail, and the horizontal drilling slide 208 is pushed forward; when the fixed drilling second servo motor 209 reverses, the horizontal drilling slide 208 slides relative to the slider of the horizontal seat 202 through the guide rail, and the horizontal drilling slide 208 is recovered backward. The front and rear adjustment of the horizontal seat 202 is realized by the fixed drilling second servo motor 209.

[0044] A connecting piece 20802 is provided on the horizontal drilling slide plate 208, and the connecting piece 20802 is detachably connected to the horizontal drilling slide plate 208, and a drill group 203 is fixedly connected to the connecting piece 20802. The drill group 203 includes a drill group drive motor 20301, a connector 20302, and a drill bit 20303. The drive motor 201 is fixedly connected to the connector 20302, and a plurality of drill bits 20303 are rotatably connected to the connector 20302. The drill group 203 can be quickly installed and removed from the horizontal drilling slide plate 208, and the drill group 203 can be quickly adjusted according to different processing requirements to improve production efficiency.

[0045] One end of the horizontal drill body 201 is fixedly connected with a feed plate 2011, and both sides of the horizontal drill body 201 are connected to the middle of the feed plate 2011 through reinforcing plates 2013. Reinforcing ribs 2014 are arranged on both sides of the horizontal seat 202, and the reinforcing ribs 2014 are fixedly connected to the horizontal drill body 201 through a fixed plate 2010. The reinforcing ribs 2014 and the fixed plate 2010 are perpendicular to each other. A guide movable plate 2015 is installed on the fixed plate 2010, and the guide movable plate 2015 is driven by a fixed drilling cylinder 2012 fixed on the fixed plate 2010. The overall rigidity of the feed plate 2011 and the horizontal drill body 201 is greatly enhanced, which prevents the plate from shaking during the feeding process and improves the quality of the finished plate.

[0046] The fixing plate 2010 is provided with a clamping mechanism 204, which includes a clamping cylinder and a swing arm. The clamping cylinder is fixedly connected to the fixing plate 2010, and the swing arm is fixedly connected to the rotating shaft of the clamping cylinder. When the plate enters the working area and the positioning and pushing actions are completed, the plate is clamped by the clamping mechanism 204, and the drilling accuracy is higher, the speed is faster, and the work efficiency is higher.

[0047] The mobile drilling mechanism 3 includes a mobile mechanism 301 and a second fixed drilling mechanism. The second fixed drilling mechanism has the same structure as the first fixed drilling mechanism. The mobile mechanism 301 is slidably connected to the second fixed drilling mechanism. The mobile mechanism includes a mobile box 30101, a first lifting cylinder 30102, a second lifting cylinder, and a mobile box servo motor.

The mobile box servo motor is fixedly connected to the top of the mobile box 30101. The first lifting cylinder 30102 and the second lifting cylinder are fixedly connected to the horizontal drilling body 201 of the second fixed drilling mechanism. A guide rail slider mechanism is arranged between the mobile box 30101 and the horizontal drilling body 201. The position of the horizontal drill body 201 can be adjusted by synchronously extending or shortening the telescopic rods of the first lifting cylinder 30102 and the second lifting cylinder. Since a guide rail slider mechanism is provided between the moving box 30101 and the horizontal drill body 201, the process of lifting the moving box 30101 or the horizontal drill body 201 below is smooth, which can effectively prevent the shaking of the horizontal drill body 201 below and maintain the accuracy of the machine parts.

[0048] There are two fixed drilling mechanisms in this device, one is fixedly connected to the main frame 1, and the other is combined into a mobile drilling mechanism 3 through a mobile mechanism 301.
