[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4A drilling device for producing crane parts includes a body 1, a placement plate fixed inside the body 1, an electric push rod fixedly mounted on the top of the placement plate, a mounting roller keyed to the output end of the electric push rod, a support plate fixedly mounted on the bottom end of the mounting roller, a drilling motor fixedly mounted on the bottom of the support plate, and a drill bit keyed to the output end of the drilling motor. A groove 4 is provided on the right side of the body 1, and a connecting plate 3 is slidably connected inside the groove 4. Springs 17 are tightly secured on both the front and rear sides of the connecting plate 3. The end of spring 17 away from connecting plate 3 is fastened to the inner wall of slide groove 4. The left side of connecting plate 3 extends into the machine body 1 and is fastened to mounting plate 5. A nozzle 2 is provided on the top of mounting plate 5. A water tank 6 is provided on the right side inside the machine body 1, and the water tank 6 and nozzle 2 are connected. The nozzle 2 is connected to the water tank 6 through a flexible water pipe. A movable column 16 is fastened to the right side of connecting plate 3, and the movable column 16 is located on the outside of the machine body 1. A central shaft 15 is fastened to the right side of the machine body 1, and a swing arm is movably sleeved on the outside of the central shaft 15. The top of the swing plate 7 is slidably connected to the outside of the moving column 16. A bidirectional motor 14 is fixedly installed on the right side of the body 1. The output end of the bidirectional motor 14 is keyed to a threaded tube 9. A sleeve 11 is screwed onto the outside of the threaded tube 9. The inside of the sleeve 11 has a threaded hole that matches the thread on the outside of the threaded tube 9. A connecting rod 10 is fastened to the top of the sleeve 11. Two sets of top blocks 8 are fastened to the top of the connecting rod 10. The two sets of top blocks 8 are located on the left and right sides of the swing plate 7, respectively. The top blocks 8 are triangular top blocks. The thickness of the top blocks 8 is greater than the thickness of the swing plate 7. Through the cooperation between the swing plate 7 and the moving column 16, when the top blocks 8 push the swing plate 7 to swing, the swing plate 7 will drive the nozzle 2 to move by pushing the moving column 16. By changing the position of the nozzle 2, the range of coolant spraying of the device can be changed, so that the device can spray coolant on different areas. The device is easy to operate, increases the range of application of the device, and facilitates the use of operators.

[0018] Specifically, in order to prevent the connecting plate 3 from being misaligned, a limiting rod 18 is fastened to the inner wall of the slide groove 4, and the connecting plate 3 is slidably connected to the outside of the limiting rod 18, thereby preventing the connecting plate 3 from being misaligned by the limiting rod 18.

[0019] Specifically, in order to prevent the swing plate 7 from being misaligned, an anti-detachment block is tightly fitted on the outside of the central shaft 15, and the anti-detachment block is located on the right side of the swing plate 7, thereby blocking the swing plate 7.

[0020] Specifically, to prevent misalignment of the sleeve 11, a balance bar 13 is tightly fastened to the right side of the body 1. The bottom of the sleeve 11 is fastened to a balance block 12 that is slidably connected to the outside of the balance bar 13. Thus, by setting the balance block 12 to be slidably connected to the outside of the balance bar 13, on the one hand, the balance bar 13 maintains the balance of the sleeve 11 during movement, preventing the sleeve 11 from becoming unbalanced and swaying during movement, and ensuring the normal displacement of the sleeve 11. On the other hand, the balance bar 13 restricts the direction of the sleeve 11, preventing the device from failing due to misalignment of the sleeve 11, and ensuring the normal use of the device.

[0021] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0022] When in use, the bidirectional motor 14 is turned on so that its output end drives the threaded tube 9 to rotate. The rotation of the threaded tube 9 will drive the sleeve 11 to move forward or backward. The operator can control the forward and backward movement of the sleeve 11 by controlling the direction of rotation of the threaded tube 9. During the movement, the sleeve 11 will drive the connecting rod 10 to drive the top block 8 to move. During the movement, the top block 8 will push the bottom of the swing plate 7. At this time, the top of the swing plate 7 will push the moving column 16 to move laterally. The movement of the moving column 16 will drive the mounting plate 5 to move laterally through the connecting plate 3. The movement of the mounting plate 5 will drive the nozzle 2 to move. Thus, by changing the position of the nozzle 2, the range of coolant spraying of the device can be changed, so that the device can spray coolant on different areas.

[0023] In summary, this drilling device for crane parts production, through the cooperation between the swing plate 7 and the moving column 16, allows the top block 8 to push the swing plate 7 to swing, which in turn pushes the moving column 16 to move the nozzle 2. By changing the position of the nozzle 2, the range of coolant spraying can be changed, enabling the device to spray coolant on different areas. Furthermore, the device is easy to operate, increasing its applicability and facilitating its use by operators.

[0024] The drilling device for producing crane parts has a balance block 12 slidably connected to the outside of the balance bar 13. On the one hand, the balance bar 13 maintains the balance of the sleeve 11 during movement, preventing the sleeve 11 from becoming unbalanced and swaying, thus ensuring the normal displacement of the sleeve 11. On the other hand, the balance bar 13 restricts the direction of the sleeve 11, preventing the device from failing due to misalignment of the sleeve 11, thus ensuring the normal use of the device.
