The first sprocket drives the second sprocket to rotate via a chain, which in turn drives the other double-grooved rod to rotate via another connecting rod. The rotation of the double-grooved rod causes the two threaded seats on the outer wall to move towards each other. The movement of the threaded seats causes the connecting plate to move, which causes the two connecting plates on the same side to move the same clamping plate.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please refer to Figures 1-6. This utility model provides a technical solution: a widely applicable mobile gantry drilling machine, including a base plate 3, a drilling machine body 1 connected to the top of the base plate 3, a support plate 2 connected to the top of the drilling machine body 1, a clamping device 4 provided in the support plate 2, the clamping device 4 including a motor 403, two moving slots 401, a chain 409 and a dustproof box 410, a first sprocket 408 and a second sprocket 411 respectively connected to the inner wall of the chain 409, a connecting rod 407 connected to one side of the first sprocket 408 and one side of the second sprocket 411, a double-threaded rod 405 connected to one end of the connecting rod 407, two threaded seats 404 threadedly connected to the outer wall of the double-threaded rod 405, a connecting plate 406 connected to one side of the threaded seat 404, and the same side of the threaded seat 404... Two connecting plates 406 are connected by the same clamping plate 402. A movable groove 401 is opened on one side of the support plate 2. The two ends of the double-grooved rod 405 are rotatably connected to the two sides of the inner wall of the movable groove 401, and the bottom of the clamping plate 402 is attached to the top of the support plate 2 and slidably connected. A through hole is opened on one side of the movable groove 401, and the through hole is rotatably connected to the outer wall of the connecting rod 407. The outer wall of the threaded seat 404 is slidably connected to the inner wall of the movable groove 401. One side of the motor 403 is fixedly installed on one side of the support plate 2, and the output shaft of the motor 403 extends into one of the movable grooves 401 and is connected to one end of one of the double-grooved rods 405. One side of the dustproof box 410 is connected to one side of the support plate 2, and the dustproof box 410 is sleeved on the outside of the first sprocket 408 and the second sprocket 411.

[0030] In a specific implementation, by setting up a clamping device 4, the output shaft of the motor 403 drives the double-threaded rod 405 to rotate, which in turn drives the connecting rod 407 to rotate. The connecting rod 407 drives the first sprocket 408 to rotate, which in turn drives the chain 409 to rotate. The chain 409 then drives the second sprocket 411 to rotate, which in turn drives another connecting rod 407 to rotate. The other connecting rod 407 drives another double-threaded rod 405 to rotate. By setting two oppositely oriented threaded sections on the outer wall of the double-threaded rod 405, the opposite threaded sections of the double-threaded rod 405 drive the two threaded seats 404 on the outer wall to move towards each other. The movement of the threaded seats 404 drives the connecting plate 406 to move. This causes the two connecting plates 406 on the same side to move the same clamping plate 402, so that the two clamping plates 402 clamp the workpiece, thereby clamping and fixing the workpiece and preventing displacement of the workpiece due to vibration during processing, thus avoiding affecting the processing accuracy of the workpiece. By setting the bottom of the clamping plate 402 to fit against the top of the support plate 2, the movement of the clamping plate 402 after drilling can scrape the waste chips on the surface of the support plate 2, so that the waste chips fall into the groove on the top of the support plate 2, thus facilitating the processing of the next workpiece. The drilling machine body 1 is equipped with multiple linear modules and drilling mechanisms. The linear modules drive the drilling mechanism to move for positioning drilling. This technology is existing technology and does not need to be described in detail.

[0031] A sealing device 5 is provided at the bottom of the inner wall of the movable groove 401. The sealing device 5 includes a movable groove 501, which is opened at the bottom of the movable groove 401. Multiple sealing blocks 502 are slidably connected in the movable groove 501. A spring 505 is connected to the bottom of the sealing block 502. The bottom of the spring 505 is connected to the bottom of the movable groove 501. Extrusion grooves 506 are opened on both sides of the threaded seat 404. The top of the sealing block 502 is provided with an inclined surface, and the top of the sealing block 502 is in contact with the top of the movable groove 401. A fixing groove is opened at the bottom of the sealing block 502, and a fixing rod 504 is slidably connected in the fixing groove. The bottom of the fixing rod 504 is connected to the bottom of the movable groove 501, and the spring 505 is sleeved on the outside of the fixing rod 504. Multiple limiting grooves are opened on both sides of the inner wall of the movable groove 501, and limiting blocks 503 are slidably connected in the limiting grooves. One side of the limiting block 503 is connected to one side of the sealing block 502.

[0032] In a specific implementation, by setting a sealing device 5, when the threaded seat 404 moves, the threaded seat 404 presses the inclined surface of one side of the sealing block 502 through the compression groove 506, causing the sealing block 502 to move downward and compress the spring 505, causing the spring 505 to generate a rebound force. A fixing rod 504 is set to support the spring 505, preventing the spring 505 from bending during compression and affecting its rebound effect. When the threaded seat 404 continues to move, the compressed sealing block 502 and the threaded seat 404... After misalignment, the sealing block 502 loses its limiting effect through the extrusion groove 506, causing the sealing block 502 to reset through the rebound of the spring 505. This allows the sealing block 502 to seal both sides of the threaded seat 404, preventing the waste generated during drilling from entering the moving groove 401 and adhering to the surface of the double-groove rod 405. This prevents the waste from affecting the transmission of the double-groove rod 405 to the threaded seat 404. By setting the limiting block 503 to slide in the limiting groove, the sealing block 502 is prevented from getting stuck when moving up and down, thus affecting the sealing effect.

[0033] Working principle: In use, the workpiece is placed on the surface of the support plate 2. Then, the motor 403 drives the double-threaded rod 405 to rotate. The double-threaded rod 405 drives the connecting rod 407 on one side to rotate. The connecting rod 407 drives the first sprocket 408 to rotate. The first sprocket 408 drives the chain 409 to rotate. The chain 409 drives the second sprocket 411 to rotate. The second sprocket 411 drives another connecting rod 407 to rotate. The other connecting rod 407 drives another double-threaded rod 405 to rotate. This causes the double-threaded rod 405 to drive the two threaded seats 404 to move towards each other through the two oppositely oriented threaded sections on its outer wall. When the thread seat 404 moves, it presses the sealing block 502 on one side, causing the sealing block 502 to move downward. The sealing block 502 on the other side of the thread seat 404 is reset by the rebound of the spring 505, thereby blocking the moving groove 401 and preventing waste from entering the moving groove 401 and affecting the movement of the thread seat 404. The movement of the thread seat 404 drives the connecting plate 406 to move, and the connecting plate 406 drives the clamping plate 402 to move, so that the clamping plate 402 clamps and fixes the workpiece, preventing the workpiece from shifting due to vibration during processing, thereby ensuring the accuracy of drilling the workpiece.
