[0002] With the continuous improvement of economic level and the continuous advancement of science and technology, the aviation industry has entered a stage of rapid development. Aircraft refers to any machine that relies on the reaction force of the air rather than the reaction force of the air on the ground to gain support in the atmosphere. Aircraft include various types of aircraft that are active in the atmosphere. Airplanes are a common type of aircraft. During the manufacturing process of aircraft, parts need to be cut, drilled, and processed.

[0003] However, it still has the following disadvantages in actual use:

[0004] Existing drilling devices for aircraft parts generally drill holes in parts by rotating drill bits. However, when drilling parts, the drill bits are easily damaged due to friction during long-term drilling. If they are not replaced in time, the drilled holes may become unusable. The existing drill bit replacement operation is relatively complicated, which increases the workload. Utility Model Content

[0005] The purpose of the utility model is to provide a drilling device for manufacturing aircraft parts, so as to solve the problem raised in the above-mentioned background technology that when drilling parts, the drill bit is easily damaged due to long-term drilling friction, and the drilled hole is easily unusable if not replaced in time, and the existing drill bit replacement operation is relatively complicated, which increases the workload.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a drilling device for manufacturing aircraft parts, comprising:

[0008] A support mechanism, the support mechanism comprising a support plate;

[0009] A clamping mechanism, the clamping mechanism comprising a turntable rotatably connected to the outer wall of the support plate;

[0010] A drilling mechanism, the drilling mechanism comprising a cylinder;

[0011] The replacement mechanism includes a first spring, the first spring is fixedly connected to an extrusion plate, a connecting shaft is placed on the lower side of the extrusion plate, a lifting block is fixedly connected to a circumferential outer wall of one side of the connecting shaft, a telescopic shaft is movably connected to the connecting shaft from top to bottom, a contact plate is placed at the lower end of the telescopic shaft, a second spring is movably connected to the lower end of the contact plate, and the bottom of the telescopic shaft is movably connected to the top of the second spring.

[0012] Furthermore, support legs are welded at the four corners of the bottom of the support plate, support frames are welded at the four corners of the top of the support plate, and a top plate is welded at the top of the support frame;

[0013] Furthermore, the bottom of the turntable is movably connected to a rotating motor, the outer wall of the top of the turntable is vertically cross-shaped with two slide grooves, the inner cavity of the slide groove is movably connected to a screw rod, and the outer wall of the screw rod is sleeved with a clamping plate;

[0014] Furthermore, the movable end of the cylinder is rotatably connected to a flange, the cylinder is fixedly mounted on the top outer wall of the top plate, and the inner circumferential wall of the flange is movably connected to a motor;

[0015] Furthermore, a connecting sleeve is sleeved on the circumferential outer wall of the motor output end, a connecting rod is threadedly connected to the circumferential inner wall of the connecting sleeve, and a connecting cylinder is welded on the bottom of the connecting rod;

[0016] Furthermore, the expansion and contraction force of the first spring is greater than the expansion and contraction force of the second spring, the first spring is movably connected to the inner wall of the circumference of the connecting tube, the connecting shaft passes through the wall of the connecting tube, and a drill is movably placed in the inner cavity of the connecting tube to contact one end of the second spring;

[0017] Furthermore, it also includes a fixing mechanism, including a sleeve disk fixedly mounted on the inner circumferential wall of the connecting cylinder, an annular groove is formed through the inner and outer sides of the sleeve disk, a third spring is movably connected in the annular groove, a clamping shaft is sleeved on the outer wall of the third spring, the clamping shaft passes through the sleeve disk, and a sleeve frame is slidably connected to the outer circumferential wall of the connecting cylinder;

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. According to the utility model, when the drill bit needs to be replaced, the connecting shaft is pressed to extend the connecting shaft into the connecting tube. When the connecting shaft just enters the connecting tube, the lifting block contacts the first spring. As the connecting shaft continues to extend, the lifting block squeezes the first spring. The connecting shaft continues to move to make the telescopic shaft contact the first spring, and the lifting block moves to the thinner end of the extrusion plate, so that the first spring rebounds and squeezes the telescopic shaft, and the telescopic shaft moves downward to squeeze the second spring. Because the rebound force of the first spring is greater than the rebound force of the second spring, the second spring pops up downward instead of popping up upward. The second spring pops up downward to move the drill bit in the connecting tube downward, and the sleeve is slid downward to loosen the clamping shaft, so that the damaged drill bit at the lower end falls off, thereby facilitating the replacement of the drill bit and reducing the replacement steps.

[0020] 2. Based on beneficial effect 1, the sleeve is moved upward to squeeze the clamping shaft and then limit its position. The drill bit moved downward by the second spring contacts the inner wall of the clamping shaft, and the drill bit continues to move downward, pushing the clamping shaft outward. The clamping shaft stretches the third spring, and the third spring rebounds, causing the rebound force to pull the clamping shaft inward, so that the third spring limits the position of the clamping shaft to clamp the drill bit, making it convenient to clamp and loosen the drill bit.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0033] See also Figure 1-4 As shown, this embodiment is a drilling device for manufacturing aircraft parts, comprising:

[0034] Support mechanism 1, support mechanism 1 comprises a support plate 101;

[0035] The clamping mechanism 2 includes a turntable 201 rotatably connected to the outer wall of the support plate 101;

[0036] The drilling mechanism 3 includes a cylinder 301;

[0037] The replacement mechanism 4 includes a first spring 401, the first spring 401 is fixedly connected to a squeeze plate 402, a connecting shaft 403 is placed on the lower side of the squeeze plate 402, a lifting block 404 is fixedly connected to a circumferential outer wall of one side of the connecting shaft 403, a telescopic shaft 405 is movably connected to the connecting shaft 403 from top to bottom, a contact plate 406 is placed at the lower end of the telescopic shaft 405, a second spring 407 is movably connected to the lower end of the contact plate 406, and the bottom of the telescopic shaft 405 is movably connected to the top of the second spring 407;

[0038] The first spring 401 rebounds to move the extrusion plate 402, and the first spring 401 is driven to contract by the extrusion plate 402, and the lifting block 404 is driven to move by the connecting shaft 403, and the first spring 401 is squeezed and contracted by the lifting block 404, and the second spring 407 is squeezed downward by the telescopic shaft 405. When the connecting shaft 403 is pulled outward, the telescopic shaft 405 is not in contact with the first spring 401, and the second spring 407 rebounds to return the telescopic shaft 405 to its original position;

[0039] The expansion and contraction force of the first spring 401 is greater than that of the second spring 407. The first spring 401 is movably connected to the inner wall of the connecting tube 306. The connecting shaft 403 penetrates the wall of the connecting tube 306. A drill bit 408 is movably placed in the inner cavity of the connecting tube 306 to contact one end of the second spring 407.

[0040] The first spring 401 squeezes the second spring 407, and the second spring 407 pops out downward. The top of the first spring 401 is fixed by the connecting tube 306, and the drill bit 408 is pushed to move by the second spring 407;

[0041] Working principle: when the drill bit 408 needs to be replaced, the connecting shaft 403 is pressed to extend the connecting shaft 403 into the connecting tube 306. When the connecting shaft 403 just enters the connecting tube 306, the lifting block 404 contacts the first spring 401. As the connecting shaft 403 continues to extend, the lifting block 404 squeezes the first spring 401. The connecting shaft 403 continues to move to make the telescopic shaft 405 contact the first spring 401, and the lifting block 404 moves to the thinner end of the extrusion plate 402, so that the first spring 401 rebounds and squeezes the telescopic shaft 405, and the telescopic shaft 405 moves downward to squeeze the second spring 407. Because the rebound force of the first spring 401 is greater than the rebound force of the second spring 407, the second spring 407 pops up downward instead of popping up. The second spring 407 pops up downward to move the drill bit 408 in the connecting tube 306 downward, and the sleeve 505 slides downward to release the clamping shaft 504.

[0042] This step causes the damaged drill bit 408 at the bottom to fall off, thereby facilitating replacement of the drill bit 408 and reducing replacement steps.
