[0019] The present invention provides a plate positioning drilling device for manufacturing a computer housing. It has the following beneficial effects:

[0020] 1. The plate positioning and drilling equipment manufactured by the computer housing, through the setting of the fixing mechanism, places the plate on the working plate, located between the clamping blocks on both sides, and is fixed by the C-shaped frame in the accommodating groove. Under the action of the clamping spring, the rotating rod drives the arc-shaped clamping plate to rotate around it, thereby clamping the plate. The arc-shaped clamping plate is evenly distributed and the outer curved surface faces the feed end, which can adapt to the shape of plates of different sizes.

[0022] 3. The plate positioning drilling equipment manufactured by the computer housing has a positioning mechanism. The rotating drum can rotate in the fixed drum, the fixed ring slides in the rotating groove, and the rotating ring is squeezed and adapted to the rotating groove. When the rotating drum rotates, its bottom squeezes the positioning ring, and the positioning ring moves downward through the linkage of rotating rod 1, rotating rod 2 and buffer spring, so that the friction ring contacts the surface of the plate.

The stabilizing frame supports and stabilizes the transmission shaft to prevent it from shaking during rotation. The motor provides the power required for drilling, the transmission shaft efficiently transmits the power, and the stabilizing frame ensures the stability of the drill bit when rotating at high speed, thereby achieving accurate drilling of the plate. The drilling mechanism can ensure the verticality and stability of the drill bit during the drilling process, reduce drilling deviation, improve drilling quality, and at the same time improve drilling efficiency to meet the production needs of computer housing manufacturing.

[0024] 5. The plate positioning and drilling equipment manufactured by the computer housing has a card block and a card slot.

[0042] Positioning mechanism 8, which is installed on the top of fixing mechanism 7, and is used to further fix the plate and perform drilling positioning on the plate to improve the stability of drilling;

[0043] The positioning mechanism 8 includes a fixed cylinder 82 and a rotating cylinder 83. A fixed frame 81 is fixedly installed on the outer surface of the fixed cylinder 82. A rotating groove 89 is opened on the inner wall of the fixed cylinder 82. A clamping groove 84 is opened on the top of the rotating cylinder 83.

The clamping members 73 on both sides work together to preliminarily clamp and fix the plate;

[0045] The clamping member 73 includes a C-shaped frame 731, which is fixedly mounted on the inner wall of the accommodating groove 72. A rotating rod 732 is rotatably mounted between the two ends of the C-shaped frame 731. An arc-shaped clamping plate 733 is fixedly mounted on the outer surface of the rotating rod 732. A clamping spring 735 is fixedly connected between the end of the arc-shaped clamping plate 733 and the middle of the C-shaped frame 731. The rotating rod 732 rotates between the two ends of the C-shaped frame 731 to drive the arc-shaped clamping plate 733 to rotate. Under the action of the clamping spring 735, the arc-shaped clamping plate 733 can adapt to the shape of the plate and clamp the plate on the working plate 6.

[0046] A positioning groove 734 is formed at one end of the arc-shaped clamping plate 733 away from the rotating rod 732 . The positioning groove 734 is arranged on the outer curved surface of the arc-shaped clamping plate 733 . The positioning groove 734 is used to assist in positioning the plate.

[0047] The outer curved surface of the arc-shaped clamping plate 733 faces the feeding end of the device, and the arc-shaped clamping plate 733 is evenly arranged inside the receiving groove 72;

[0048] The positioning member 85 includes a rotating rod 851 and a positioning ring 853. The rotating rod 851 is rotatably mounted on the edge of the bottom of the fixed cylinder 82 via a rotating shaft. There are eight rotating rods 851, and the eight rotating rods 851 are evenly distributed along the axis of the fixed cylinder 82. The other end of the rotating rod 851 is rotatably connected to the rotating rod 852 via a rotating shaft. The other end of the rotating rod 852 is rotatably mounted on the outer side of the positioning ring 853 via a rotating shaft. The positioning ring 853 is driven to move by the rotating cylinder 83, and the rotating rod 852 and the rotating rod 851 are gradually opened.

[0049] A buffer spring 855 is fixedly connected between the rotating rod 1 851 and the rotating rod 2 852. The buffer spring 855 plays a buffering role when the rotating rod 2 852 and the rotating rod 1 851 are opened. A friction ring 854 is fixedly installed at the bottom of the positioning ring 853. The friction ring 854 increases the friction with the plate and improves the positioning stability. The bottom of the rotating drum 83 is squeezed and adapted to the top of the positioning ring 853.

[0050] The third embodiment is based on the first and second embodiments. Figure 4 As shown, the drilling mechanism 5 includes a motor 51, which is fixedly mounted on the top of the lifting plate 44 through a bracket, and a transmission shaft 52 is fixedly connected to the output end of the motor 51, and a mounting seat 54 is fixedly mounted on the end of the transmission shaft 52 away from the motor 51, and a drill bit 55 is fixedly mounted on the bottom of the mounting seat 54, and a stabilizing frame 53 is rotatably mounted on the outer surface of the transmission shaft 52, and the stabilizing frame 53 is fixedly mounted on the bottom of the lifting plate 44, and the stabilizing frame 53 is used to support and stabilize the transmission shaft 52, reduce the shaking of the transmission shaft 52 during rotation, and improve the accuracy of drilling;

[0051] When the lifting mechanism 4 drives the drilling mechanism 5 to descend to a suitable position, the block 56 at the bottom of the mounting seat 54 is engaged with the slot 84 at the top of the rotating drum 83. When the motor 51 drives the transmission shaft 52 to rotate, the rotating drum 83 is driven to rotate synchronously through the engaging structure, thereby realizing the power connection between the drilling mechanism 5 and the positioning mechanism 8, so that the rotation of the drill bit 55 can drive the plate to rotate synchronously under the condition of precise positioning, thereby improving the drilling efficiency and ensuring the accuracy of the drilling position.

[0052] When in use, the operator pushes the computer housing plate to be drilled into the fixing mechanism 7. The arc-shaped clamping plate 733 in the fixing mechanism 7 tightly clamps the edge of the plate under the action of the clamping spring 735. Since the arc-shaped clamping plate 733 is evenly arranged and the outer curved surface faces the feed end, it can adapt to plates of different sizes and provide stable clamping. At the same time, the positioning groove 734 can cooperate with the edge of the plate to play a preliminary positioning role.

[0053] At the same time, the telescopic end of the cylinder 41 drives the telescopic rod 42 to extend and retract, and then the lifting plate 44 moves up and down along the guide rail 3 through the connecting block 43, and the sliding sleeve 45 slides on the guide rail 3 to ensure the stability of the movement of the lifting plate 44, so that the drilling mechanism 5 reaches a suitable height;

[0054] The motor 51 is started, and the motor 51 drives the mounting seat 54 and the drill bit 55 to rotate through the transmission shaft 52. The stabilizing frame 53 supports and stabilizes the transmission shaft 52 to ensure the stability of the rotation of the drill bit 55.

[0055] When the drill bit 55 is lowered to a suitable position, the block 56 at the bottom of the mounting seat 54 engages with the slot 84 at the top of the rotating drum 83, so that the rotation of the drill bit 55 can drive the rotating drum 83 to rotate, and then drive the plate to rotate under precise positioning through the positioning mechanism 8, so as to realize drilling holes at different positions of the plate;

[0056] The fixed cylinder 82 of the positioning mechanism 8 is fixed by the fixed frame 81, the rotating cylinder 83 can rotate in the fixed cylinder 82, the fixed ring 86 slides in the rotating groove 89, and the rotating ring 88 is pressed and adapted with the rotating groove 89, so that the rotating cylinder 83 can rotate flexibly relative to the fixed cylinder 82 and maintain a certain stability;

[0057] During positioning, the bottom of the rotating drum 83 squeezes the positioning ring 853, so that the positioning ring 853 moves downward through the action of the rotating rod 1 851, the rotating rod 2 852 and the buffer spring 855, and the friction ring 854 at the bottom contacts the surface of the plate, and the plate is accurately positioned by friction.

[0058] After the drilling is completed, the cylinder 41 drives the lifting plate 44 to rise, so that the drill bit 55 leaves the plate, and the plate with the drilled hole is taken out from the discharge end of the fixing mechanism 7, completing the entire work process.
