A clamping motor 236 is fixedly installed on the left side of the drive box 235. The output shaft of the clamping motor 236 passes through the inner cavity of the drive box 235 and is fixedly installed with a positive and negative threaded rod 237. The left and right sides of the positive and negative threaded rod 237 are provided with threads of the same type. The outer walls of the two threaded walls are threadedly mounted with moving rods 238, the front side of the driving box 235 is provided with a moving groove that penetrates to the inner cavity, the front ends of the two moving rods 238 penetrate the moving groove to the front side of the driving box 235 and are fixedly mounted with a clamping plate 239, the tops of several driving boxes 235 are fixedly mounted with electric push rods 2351, the output ends of the electric push rods 2351 are fixedly mounted with a push plate 2352, and the middle part of the front side of the mounting plate 231 is fixedly mounted with an infrared emitter 2311;

[0022] When loading, the workpieces are placed one by one on the grid plate 234 on the top of the mounting plate 231, and then the clamping motor 236 on the driving box 235 is started to drive the forward and reverse threaded rod 237 in the inner cavity of the driving box 235 to rotate, so that the two moving rods 238 on the left and right sides of the forward and reverse threaded rod 237 are brought close to each other, and drive the two clamping plates 239 to clamp and fix the workpiece, and then the rotating motor 12 in the motor slot 11 drives the overall turntable 21 to rotate counterclockwise, so that the overall workpiece positioning mechanism 23 rotates counterclockwise, and moves one by one to the front side of the drilling mechanism 3 to perform drilling operations.

[0023] like Figure 4As shown, the drilling mechanism 3 includes a vertical plate 31, which is fixedly installed on the top of the drilling platform 1, an infrared receiver 32 is fixedly installed on the lower front side of the vertical plate 31, a U-shaped plate 33 is fixedly installed on the upper front side of the vertical plate 31, an adjustment cabin 34 is opened inside the left side of the U-shaped plate 33, a motor 35 is fixedly installed on the left front end of the U-shaped plate 33, the output shaft of the motor 35 passes through the inner cavity of the adjustment cabin 34 and is fixedly installed with a threaded rod 36, and a moving plate 37 is threadedly installed on the outer wall of the threaded rod 36, a sliding groove is opened on the right side of the inner wall of the adjustment cabin 34 and passes through the right side of the front and rear horizontal position of the left U-shaped plate 33, the right end of the moving plate 37 passes through the sliding groove and is fixedly installed with a hanging plate 38, a hydraulic push rod 39 is fixedly installed on the top of the hanging plate 38, and the output end of the hydraulic push rod 39 passes through the bottom of the hanging plate 38 and is fixedly installed with a drilling machine;

At this time, the bottom drilling machine can be driven down by starting the hydraulic push rod 39, and the high-speed rotating drill bit of the drilling machine is used to drill holes in the workpiece. When the workpiece is not positioned directly below the bottom drilling machine of the hydraulic push rod 39, the motor 35 on the left side of the front end of the U-shaped plate 33 is started to drive the threaded rod 36 to rotate, so that the movable plate 37 moves in the adjustment cabin 34, thereby driving the hanging plate 38 used to fix the hydraulic push rod 39 to move back and forth, thereby facilitating the adjustment of the position of the drilling machine.

[0025] like Figure 5 As shown, the workpiece collecting mechanism 4 includes an inclined plate 41, which is fixedly installed on the right side of the drilling platform 1, and guard plates 42 are fixedly installed on both the front and rear sides of the top of the inclined plate 41.

At the same time, the output end of the electric push rod 2351 will drive the push plate 2352 forward, push the workpiece off the guide plate 43, and use the inclined plate 41 to slide to the right, and cooperate with the two guard plates 42 for limiting, until it falls into the workpiece collection box 46 to complete the unloading.

[0027] The working principle of the loading and unloading device of the drilling machine used for shipbuilding is described in detail below.

[0028] like Figure 1-5 As shown, when loading, the workpieces are placed one by one on the grid plate 234 on the top of the mounting plate 231, and then the clamping motor 236 on the driving box 235 is started to drive the positive and negative threaded rod 237 in the inner cavity of the driving box 235 to rotate, so that the two moving rods 238 on the left and right sides of the positive and negative threaded rod 237 are brought close to each other, and the two clamping plates 239 are driven to clamp and fix the workpiece, and then the rotating motor 12 in the motor slot 11 drives the overall turntable 21 to rotate counterclockwise, so that the overall workpiece positioning mechanism 23 is rotated counterclockwise. When the mounting plate 231 moves to the front side of the vertical plate 31, the infrared rays emitted by the infrared transmitter 2311 will be received by the infrared receiver 32 on the front side of the vertical plate 31, and the infrared receiver 32 will send a signal to the rotating motor 12 to stop the output shaft of the rotating motor 12. At this time, the bottom drilling machine can be driven down by starting the hydraulic push rod 39, and the high-speed rotating drill bit of the drilling machine is used to drill holes in the workpiece. The debris generated during drilling will use the gap of the grid plate 234 to fall into the inner cavity of the debris collection box 233 in the card slot 22. When cleaning, it is only necessary to remove the grid plate 234 and then pull the debris collection box 233 upwards. When the workpiece is not positioned directly below the drilling machine at the bottom of the hydraulic push rod 39, the motor 35 on the left side of the front end of the U-shaped plate 33 is started to drive the threaded rod 36 to rotate, so that the movable plate 37 moves in the adjustment cabin 34, thereby driving the hanging plate 38 used to fix the hydraulic push rod 39 to move back and forth, so as to facilitate the adjustment of the position of the drilling machine. The workpiece after drilling will continue to rotate. When it moves to the left side of the inclined plate 41, the infrared emitter The infrared rays emitted by the device 2311 are received by the infrared receiver 45, and the infrared receiver 45 can send signals to the clamping motor 236 and the electric push rod 2351, so that the positive and negative threaded rods 237 are reversed to release the two clamping plates 239 from limiting the workpiece. At the same time, the output end of the electric push rod 2351 will drive the push plate 2352 forward, push the workpiece off the guide plate 43, and use the inclined plate 41 to slide to the right, and cooperate with the two guard plates 42 for limiting, until it falls into the workpiece collection box 46 to complete the unloading.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
