[0002] The drilling device for shipbuilding is a mechanical equipment used to drill holes in the hull or its related parts. Since the volume of the hull is large during the shipbuilding process, the holes drilled during the manufacturing process are large, so a drilling device dedicated to shipbuilding is required.

[0003] The existing Chinese patent publication number CN113070511A discloses a drilling device for shipbuilding. The patent mainly installs the drill rod through the connector at the other end of the transmission shaft. The housing is provided with a collecting mechanism and an auxiliary mechanism. The collecting mechanism includes a filter assembly and at least two collecting assemblies. The drilling device for shipbuilding realizes the function of collecting debris generated during drilling through the collecting mechanism to prevent the debris from splashing and injuring people. In addition, the auxiliary mechanism is used to prevent the drill rod from deviating during drilling, thereby improving the drilling accuracy. However, the drilling device also has the following defects:

[0004] When the above-mentioned drilling equipment is used for drilling in the process of shipbuilding, the drilling depth is strictly controlled during shipbuilding, but it is difficult to stably limit the drilling depth during drilling, which can easily cause the drilling to be too deep or too shallow, directly affecting the accuracy of shipbuilding.

[0023] The working principle of this embodiment is as follows:

[0024] When adjusting the drilling limit, the rotating cap 12 is rotated to drive the adjusting screw 11 to rotate forward inside the sleeve frame plate 13, and the adjusting screw 11 drives the threaded sleeve limit block 8 to move to the right along the inner wall of the sleeve frame plate 13 under the action of the thread, and at the same time, the threaded sleeve limit block 8 drives the limit pointer 9 to move to the right along the sleeve frame plate 13, and the threaded sleeve limit block 8 drives the linkage limit plate 7 to move the limit collar block 5, and the limit collar block 5 drives the three limit support blocks 6 to move to the right, and the reinforcement block 14 reinforces the sleeve frame plate 13, and the limit pointer 9 moves along the scale line value of the limit scale 10. When the tip of the limit pointer 9 moves to the specified depth value position of the limit scale 10, stop rotating the rotating cap 12, and the limit collar block 5 moves to the right along the outer wall of the ship parts drill bit 4 to the specified depth limit distance;

[0025] When drilling, the shipbuilding drilling motor 3 is started to drive the ship parts drill bit 4 to rotate, and at the same time, the pushing end of the electric cylinder 15 is pushed to drive the linkage rod 2 to move the shipbuilding drilling motor 3 to the left, and the shipbuilding drilling motor 3 drives the ship parts drill bit 4 to move to the left to contact the right side of the shipbuilding part to drill a hole. When the ship parts drill bit 4 enters the interior of the shipbuilding part, the three limiting support blocks 6 support the limiting collar block 5. The limiting collar block 5 contacts the position of the shipbuilding part, and provides multi-point precise limiting support for the drilling depth of the ship parts drill bit 4, so as to prevent the ship parts drill bit 4 from drilling too deep or too shallow.
