[0018] Beneficial effects of the present invention:

[0019] 1. The present invention starts the electric push rod and pushes it forward. At this time, the driving plate moves synchronously. When the driving plate moves, it drives the side wheels to rotate. When the side wheels rotate, the fixed block is synchronously driven to rotate through the rotating rod until the fixed block drives the drilling unit below it to flip ninety degrees. At this time, the symmetrical plate is moved toward the side of the lifting rod, and the lifting rod is controlled to move downward until the drill bit on the drilling unit is toward the required drilling position on the side of the workpiece, so that the position of the drill bit can be quickly adjusted while drilling the holes on the surface of the workpiece, and then the side of the workpiece is punched and drilled.

[0020] 2. The present invention drives the cross plate to slide in the cross cylinder through the extension and retraction of the hydraulic rod. When the cross plate slides, it drives the regulating rod to extend and retract, thereby adjusting the depth of the drilling of the drill bit below it. At the same time, when the cross plate slides, it synchronously drives the piston rod to press in the pressing cylinder through the connecting plate. At this time, the air pressure cools down the high temperature generated by the drill bit below when punching and drilling through the air pipe. While cooling and dissipating the heat of the drill bit, the wind blown out of the air pipe can also clean the waste during punching so that the waste will adhere to the drill bit.

[0021] 3. The present invention drives the rotating plate to rotate by opening the electric slider. When the rotating plate rotates, the notch on the conversion plate is driven to change position by the shifting column. When the notch on the conversion plate changes position, the lifting member below is also driven to change position. Finally, the drill bit under the required lifting member is transferred to the bottom of the regulating rod. When drilling a workpiece, the motor in the lifting member is turned on to drive the drill bit to punch the workpiece, thereby satisfying the drilling operation of drill bits of different diameters.

[0022] 4. The present invention facilitates the support of the workpiece during the punching operation by providing a support plate, making the workpiece more stable when the punching operation is completed. At the same time, the electric slider is opened to drive the support plate to rotate through the pull plate, so that the support plate can not only support the workpiece but also dump the waste generated during the punching.

[0023] 5. The present invention drives the driving wheel to rotate by turning on the driving machine. When the driving wheel rotates, the gears on both sides slide to drive the gears on both sides to rotate in the same direction. When the gears on both sides rotate, the threaded rods on both sides are driven to rotate, so that the two limit members on the threaded rods are moved closer to or farther away from each other, so as to meet the requirements of the length clamping of workpieces of different specifications. The spacing between the side plates on both sides is adjusted by the telescopic movement of the two-way telescopic plates on both sides. At this time, the spacing of the limit members on the side plates on both sides is adjusted to achieve the width clamping of workpieces of different specifications before operation, so that the entire device can meet the requirements of the punching operation of workpieces of different specifications.

[0041] By means of multiple slides 222 sliding in the dovetail groove 221, when the electric slider is turned on, it drives the screw 23 to rotate, and the rotation of the screw 23 drives the regulating plate 26 to move up and down. At this time, the regulating groove 27 drives the slide 222 to move, thereby driving the slide 222 to slide in the dovetail groove 221, and then adjusting the drilling unit 4 on the front side of the slide 222 to meet the needs of multi-station punching and drilling of the workpiece.

[0042] A rotating rod 31 is installed in the middle of the center frame 3 for horizontal rotation, a fixed block 32 is fixedly installed on the outer side of the rotating rod 31, a drilling unit 4 is fixedly installed on the lower end surface of the fixed block 32, and a side wheel 33 for adjusting the drilling direction of the drilling unit 4 is fixedly installed on one side of the rotating rod 31. The angle of the drilling unit 4 is adjusted to meet various drilling requirements on the surface or side of the workpiece, and a placement unit 6 is provided above the convex plate 1.

[0043] A screw rod 23 and a slide rod 24 are respectively arranged on both sides of the vertical frame 22. The screw rod 23 is rotationally connected to the vertical frame 22 through an electric slider, and the slide rod 24 is fixedly connected to the vertical frame 22. Lifting blocks 25 are provided on the screw rod 23 and the slide rod 24. The lifting blocks 25 on the screw rod 23 are threadedly connected to the screw rod 23 and the lifting blocks 25 on the slide rod 24 are slidably connected to the screw rod 23. The lifting blocks 25 on both sides are fixedly connected to the regulating plate 26.

[0044] A lower frame 34 is fixedly installed on the lower part of one side of the center frame 3, an electric push rod 35 is fixedly installed on one side of the lower frame 34, a driving plate 36 slidably connected to the lower frame 34 is fixedly installed on the telescopic end of the electric push rod 35, the driving plate 36 is located below the side wheel 33 and meshes with it, the drilling unit 4 includes an upper plate 41 connected to the fixed block 32, a cross cylinder 42 is fixedly installed on the lower side of the upper plate 41, a lower plate 43 is fixedly installed on the side of the cross cylinder 42 away from the upper plate 41, and a cross plate 44 is slidably installed in the cross cylinder 42.

[0045] When drilling a hole on the side of the workpiece, turn on the electric push rod 35 and push it forward. At this time, the driving plate 36 moves synchronously. When the driving plate 36 moves, it drives the side wheel 33 to rotate. When the side wheel 33 rotates, it drives the fixed block 32 to rotate synchronously through the rotating rod 31 until the fixed block 32 drives the drilling unit 4 below it to flip ninety degrees. At this time, the symmetrical plate 21 is moved toward the side of the lifting rod 2, and the lifting rod 2 is controlled to move downward until the drill bit 59 on the drilling unit 4 is facing the required drilling position on the side of the workpiece, so that the position of the drill bit 59 can be quickly adjusted while drilling the surface of the workpiece, and then the side of the workpiece is punched and drilled. Compared with the traditional CNC drilling machine, when drilling holes on the surface and side of the workpiece, there is no need to perform cumbersome flipping and adjustment of the workpiece, which greatly improves the work efficiency.

[0046] A hydraulic rod 441 is fixedly installed on the top of the inner cavity of the cross cylinder 42. The telescopic end of the hydraulic rod 441 is fixedly connected to the upper end surface of the cross plate 44. A regulating rod 442 is fixedly installed on the lower end surface of the cross plate 44. The regulating rod 442 penetrates and slides in the lower plate 43.

[0047] A pressing cylinder 45 is fixedly installed on one side of the upper end surface of the lower plate 43, and a piston rod 46 is provided in the inner cavity of the pressing cylinder 45. The piston rod 46 penetrates and slides on one side of the upper plate 41, and a connecting plate 47 is fixedly installed on one side of the piston rod 46. The connecting plate 47 is fixedly connected to the cross plate 44 on the side away from the piston rod 46, and a blowing pipe 48 connected to the inner cavity of the pressing cylinder 45 is fixedly installed on the lower part of one side of the pressing cylinder 45.

[0048] The cross plate 44 is driven to slide in the cross cylinder 42 by the extension and retraction of the hydraulic rod 441. When the cross plate 44 slides, it drives the regulating rod 442 to extend and retract, thereby adjusting the depth of the hole drilled by the drill bit 59 below it. At the same time, when the cross plate 44 slides, it synchronously drives the piston rod 46 to press in the pressing cylinder 45 through the connecting plate 47. At this time, the air pressure cools down the high temperature generated by the drill bit 59 below when punching and drilling through the blowing pipe 48. While cooling and dissipating the drill bit 59, the wind blown out of the blowing pipe 48 can also clean the waste during punching, so that the waste will not adhere to the drill bit 59, affecting the normal operation of the drill bit 59, thereby increasing the service life of the drill bit 59.

[0049] An extension frame 51 is fixedly installed on the side of the cross cylinder 42 away from the pressing cylinder 45, and a rotating plate 53 is rotatably installed on the lower part of the extension frame 51 away from the cross cylinder 42 through an electric slider. A shifting column 54 is fixedly installed on one side of the lower end surface of the rotating plate 53, and a shifting rod 55 is rotatably installed on the side of the lower plate 43 away from the pressing cylinder 45. A conversion plate 56 is fixedly installed on the upper end surface of the conversion rod 55, and a plurality of slots are provided on the conversion plate 56.

[0050] A synchronous plate 57 is fixedly installed on the lower end surface of the shift rod 55, and a plurality of lifting members 58 are circumferentially arranged on the synchronous plate 57 and are arranged correspondingly to the grooves on the conversion plate 56. The lifting members 58 are connected to the synchronous plate 57 for vertical sliding. A spring is sleeved on the outer side of the lifting member 58 and the spring is located above the synchronous plate 57. The lower end surface of the lifting member 58 is connected to a drill bit 59 through a motor rotation.

[0051] When the hole size of the punching hole in the workpiece is adjusted, drill bits 59 of different diameters are selected for drilling operations, and the electric slider is opened to drive the rotating plate 53 to rotate. When the rotating plate 53 rotates, the notch on the conversion plate 56 is driven by the shifting rod 54 to change its position. When the notch on the conversion plate 56 changes its position, the lifting member 58 below is also driven to change its position. Finally, the drill bit 59 under the required lifting member 58 is transferred to the bottom of the regulating rod 442. When drilling the workpiece, the motor in the lifting member 58 is turned on to drive the drill bit 59 to punch the workpiece.

[0052] The placement unit 6 includes two symmetrically arranged two-way telescopic plates 61, and side plates 62 are fixedly installed on both sides of the two-way telescopic plates 61. A rectangular groove is opened in the middle of the side plate 62, and a rotatably installed threaded rod 63 is installed. Moving parts 64 are rotatably installed on both sides of the threaded rod 63. The moving parts 64 pass through and slide in the rectangular groove. A limiting part 65 is fixedly installed on one side of the moving part 64, and the angles between the limiting parts 65 on the multiple moving parts 64 are relative.

[0053] A gear 66 is fixedly installed on one side of the threaded rod 63, and a tooth plate 69 is meshed on the two gears 66 on the side away from each other. A driving machine 67 is fixedly installed in the middle of the two-way telescopic plate 61 on one side, and a driving wheel 68 is fixedly installed on the driving machine 67. The upper and lower sides of the driving wheel 68 are respectively meshed with the tooth plates 69 on the upper and lower sides, and the tooth plates 69 on the upper and lower sides are respectively slidably connected to the side plates 62 on both sides.

[0054] The driving machine 67 is turned on to drive the driving wheel 68 to rotate. When the driving wheel 68 rotates, the toothed plates 69 on both sides slide and drive the gears 66 on both sides to rotate in the same direction. When the gears 66 on both sides rotate, the threaded rods 63 on both sides are driven to rotate, so that the two limit members 65 on the threaded rods 63 are moved closer to or away from each other, so as to meet the length clamping requirements of workpieces of different specifications. The distance between the side plates 62 on both sides is adjusted by the extension and retraction of the two-way telescopic plates 61 on both sides. At this time, the distance between the limit members 65 on the side plates 62 on both sides is adjusted to achieve width clamping of workpieces of different specifications before operation, so that the entire device can meet the punching requirements of workpieces of different specifications.

[0055] A supporting plate 620 is rotatably installed under the side plates 62 on both sides, and a pulling plate 621 is rotatably installed on one side of the supporting plate 620. The pulling plate 621 is rotatably connected to the bidirectional telescopic plate 61 via an electric slider away from the supporting plate 620.

[0056] The support plate 620 is provided to facilitate the support of the workpiece during the punching operation, so that the workpiece is more stable when the punching operation is completed. At the same time, the electric slider is opened to drive the support plate 620 to rotate through the pull plate 621, so that the support plate 620 can not only support the workpiece but also dump the waste generated during punching.

[0057] When the present invention is in use, firstly, the workpiece to be processed is placed in the middle of the two supporting plates 620, and then the driving machine 67 is turned on to drive the driving wheel 68 to rotate. When the driving wheel 68 rotates, the toothed plates 69 on both sides slide and drive the gears 66 on both sides to rotate in the same direction. When the gears 66 on both sides rotate, they drive the threaded rods 63 on both sides to rotate, so that the two limit members 65 on the threaded rods 63 are moved closer to or away from each other to clamp the length of the two sides of the workpiece. Then, the telescopic movement of the two-way telescopic plates 61 on both sides drives the side plates 62 on both sides to adjust the spacing. At this time, the limit members 65 on the side plates 62 on both sides are used to adjust the spacing to achieve the width clamping of the workpiece.

[0058] A plurality of slides 222 slide in the dovetail groove 221. When the electric slide block is turned on, the screw 23 is driven to rotate. The screw 23 rotates and drives the regulating plate 26 to move up and down. At this time, the regulating groove 27 drives the slide 222 to move, thereby driving the slide 222 to slide in the dovetail groove 221, and then the drilling unit 4 on the front side of the slide 222 is adjusted to meet the requirements of multi-station punching and drilling of the workpiece.

[0059] When drilling a hole on the side of the workpiece, the electric push rod 35 is turned on and pushed forward. At this time, the driving plate 36 moves synchronously. When the driving plate 36 moves, it drives the side wheels 33 to rotate. When the side wheels 33 rotate, it drives the fixed block 32 to rotate synchronously through the rotating rod 31, until the fixed block 32 drives the drilling unit 4 below it to flip ninety degrees. At this time, the symmetrical plate 21 is moved toward the side of the lifting rod 2, and the lifting rod 2 is controlled to move downward until the drill bit 59 on the drilling unit 4 is facing the required drilling position on the side of the workpiece, so that the position of the drill bit 59 can be quickly adjusted while drilling the hole on the surface of the workpiece, and then the side of the workpiece is punched and drilled;

[0060] The extension and retraction of the hydraulic rod 441 drives the cross plate 44 to slide in the cross cylinder 42. When the cross plate 44 slides, it drives the regulating rod 442 to extend and retract, thereby adjusting the depth of the hole drilled by the drill bit 59 below it. At the same time, when the cross plate 44 slides, it synchronously drives the piston rod 46 to press in the pressing cylinder 45 through the connecting plate 47. At this time, the air pressure cools down the high temperature generated by the drill bit 59 below when punching and drilling through the air pipe 48. While cooling and dissipating the drill bit 59, the air blown out of the air pipe 48 can also clean the waste during punching so that the waste will adhere to the drill bit 59.

[0061] When the hole size of the punching hole in the workpiece is adjusted, drill bits 59 of different diameters are selected for drilling operations, and the electric slider is opened to drive the rotating plate 53 to rotate. When the rotating plate 53 rotates, the notch on the conversion plate 56 is driven by the shifting rod 54 to change its position. When the notch on the conversion plate 56 changes its position, the lifting member 58 below is also driven to change its position. Finally, the drill bit 59 under the required lifting member 58 is transferred to the bottom of the regulating rod 442. When drilling the workpiece, the motor in the lifting member 58 is turned on to drive the drill bit 59 to punch the workpiece.

[0062] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
