[0002] The cutting of aircraft parts is a crucial step in the aircraft manufacturing process. There are many kinds of aviation materials, including aluminum alloys, titanium alloys, composite materials, etc. Different materials require different cutting methods to ensure their performance is not damaged. Various parts of aircraft need to be cut to make the raw materials into the size people need.
[0003] When existing equipment is cutting component raw materials, it is necessary to limit the raw materials. After the existing equipment has limited the raw materials, the position of the raw materials relative to the limiting device is usually fixed, and the limiting device used for limiting is also in an immobile state. This leads to the situation that in actual use, when the cutting workload is large and the next section of raw materials needs to be cut after completing one cutting, the staff needs to frequently release the limit, adjust the position of the raw materials, and then limit them again, which is very cumbersome. Utility Model Content

[0011] In a preferred solution, a second helical gear is rotatably installed inside the I-beam, and the second helical gear is meshed and connected with the first helical gear.
[0012] In a preferred solution, a spline shaft is rotatably mounted inside the work table, and an internal fixed sleeve of the second helical gear is provided with a spline sleeve, and the spline sleeve is slidably sleeved on the surface of the spline shaft.
[0013] In a preferred solution, a first motor is fixedly installed on the right side of the work table, and an output end of the first motor is fixedly connected to the right side of the spline shaft.
[0014] In a preferred solution, a moving mechanism is provided inside the work table, and the moving mechanism includes a slide groove, the slide groove is opened on the top of the work table, and the I-beam is slidably sleeved inside the slide groove.
[0015] In a preferred embodiment, the spline shaft is rotatably sleeved inside the slide groove, a driving screw is rotatably installed inside the slide groove, a limiting rod is fixedly installed inside the slide groove, the driving screw and the limiting rod are both sleeved inside the I-beam, and the driving screw and the I-beam are threadedly connected.

[0019] 2. By setting up a moving mechanism, since the sliding sleeve of the spline sleeve is arranged on the surface of the spline shaft, the spline shaft can always drive the spline sleeve to rotate without affecting the left and right movement of the I-beam.

DETAILED DESCRIPTION
[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Example 1
[0028] Reference Figure 1-4The utility model provides a technical solution: a cutting limit device for aircraft parts, including a work table 1 and a cutting machine 2. A limit mechanism is provided on the top of the work table 1. The limit mechanism includes an I-beam 301. The I-beam 301 is arranged inside the work table 1. A limit slot 302 is provided on the top of the I-beam 301. A two-way screw rod 303 is rotatably installed inside the limit slot 302. A limit plate 304 is slidably installed inside the limit slot 302. Two limit plates 304 are provided. The two limit plates 304 are respectively sleeved on both sides of the two-way screw rod 303 and are both threadedly connected to the two-way screw rod 303. Two limit blocks 305 are provided. The two limit blocks 305 are respectively fixedly installed on the top of the two limit plates 304. The two limit blocks 305 are relative to each other. A duckbill groove 306 is provided on one side of each of the two limit blocks 305, and the two limit blocks 305 are arranged in a mirror image. By setting a limit mechanism, the staff places the component raw material between the two limit blocks 305, and by rotating the bidirectional screw rod 303, the two limit plates 304 are respectively threadedly connected to the two ends of the bidirectional screw rod 303 in opposite directions, and through the cooperation of the limit groove 302, the two limit plates 304 respectively drive the two limit blocks 305 to move in opposite directions, so that the component raw material is clamped, and rubber pads can be installed on the opposite sides of the two limit blocks 305 to prevent the limit blocks 305 from damaging the component raw material, so that the component raw material is limited by the limit mechanism, avoiding the problem of inaccurate cutting accuracy caused by the shaking of the component raw material during cutting;
[0029] Reference Figure 1-4 The first bevel gear 307 is installed for rotation inside the I-beam 301. The first bevel gear 307 is fixedly sleeved on the surface of the bidirectional screw rod 303. The second bevel gear 308 is installed for rotation inside the I-beam 301. The second bevel gear 308 is meshed with the first bevel gear 307. By setting the first bevel gear 307 and the second bevel gear 308, when the second bevel gear 308 rotates, the meshing connection between the second bevel gear 308 and the first bevel gear 307 causes the first bevel gear 307 to rotate. Since the first bevel gear 307 is fixedly sleeved on the surface of the bidirectional screw rod 303, the first bevel gear 307 can drive the bidirectional screw rod 303 to rotate.
[0030] Reference Figure 1-4The work table 1 is internally rotatably installed with a spline shaft 309, and the internal fixed sleeve of the second helical gear 308 is provided with a spline sleeve 310. The spline sleeve 310 is slidably sleeved on the surface of the spline shaft 309. The right side of the work table 1 is fixedly installed with a first motor 311. The output end of the first motor 311 is fixedly connected to the right side of the spline shaft 309. By setting the spline shaft 309, the staff starts the first motor 311 to drive the spline shaft 309 to rotate. Due to the meshing between the spline shaft 309 and the spline sleeve 310, the spline shaft 309 and the spline sleeve 310 are engaged. , so that the spline shaft 309 drives the spline sleeve 310 to rotate. Since the spline sleeve 310 is fixedly sleeved inside the second helical gear 308, the second helical gear 308 is driven to rotate by the spline sleeve 310, so that the two limit blocks 305 move in relative directions to clamp the component raw material. Moreover, since the spline sleeve 310 is slidably sleeved on the surface of the spline shaft 309, the spline shaft 309 can drive the spline sleeve 310 to rotate without affecting the left and right movement of the spline sleeve 310.
[0031] Example 2
[0032] In the above embodiment, the relative movement of the two limiting blocks 305 can limit the position of the component material relative to the I-beam 301. However, since the I-beam 301 cannot be moved, when a large number of cutting processes are carried out, the staff needs to frequently adjust the position of the component material, which is very cumbersome and needs to be improved.
[0033] Reference Figure 1-4, this embodiment is different from the above-mentioned embodiment 1 in that a moving mechanism is provided inside the work table 1, and the moving mechanism includes a slide 401, the slide 401 is opened on the top of the work table 1, the I-beam 301 is slidably sleeved inside the slide 401, the spline shaft 309 is rotatably sleeved inside the slide 401, a driving screw 402 is rotatably installed inside the slide 401, a limit rod 403 is fixedly installed inside the slide 401, the driving screw 402 and the limit rod 403 are both sleeved inside the I-beam 301, the driving screw 402 and the I-beam 301 are threadedly connected, a second motor 404 is fixedly installed on the right side of the work table 1, and the output end of the second motor 404 is fixedly connected to the right side of the driving screw 402. By setting the moving mechanism , the staff starts the second motor 404 to drive the driving screw 402 to rotate. Due to the threaded connection between the driving screw 402 and the I-beam 301, and the sliding connection between the limit rod 403 and the I-beam 301, the I-beam 301 moves along the direction of the slide groove 401, and because the spline sleeve 310 is slidingly sleeved on the surface of the spline shaft 309, the spline shaft 309 can always drive the spline sleeve 310 to rotate without affecting the left and right movement of the I-beam 301. As a result, when the staff has cut a section of component raw material and needs to cut the next section of raw material, there is no need to frequently release the limit of the component raw material, adjust the position and then limit it again. Compared with the existing technology, the efficiency of component cutting is higher.
[0034] Specifically, the working process or working principle of the aircraft component cutting limit device is as follows: when in use, the staff places the component raw material between the two limit blocks 305, starts the first motor 311, drives the spline shaft 309 to rotate, and due to the engagement between the spline shaft 309 and the spline sleeve 310 key teeth, the spline shaft 309 drives the spline sleeve 310 to rotate, and since the spline sleeve 310 is fixedly sleeved inside the second bevel gear 308, the second bevel gear 308 is driven to rotate through the spline sleeve 310. When the second bevel gear 308 rotates, the second bevel gear 308 and the first bevel gear 307 are connected. The meshing connection causes the first bevel gear 307 to rotate. Since the first bevel gear 307 is fixedly sleeved on the surface of the bidirectional screw rod 303, the first bevel gear 307 can drive the bidirectional screw rod 303 to rotate, so that the two limit blocks 305 move in relative directions to clamp the component raw materials. When the lower section of the raw materials needs to be cut, the staff starts the second motor 404 to drive the driving screw rod 402 to rotate. Due to the threaded connection between the driving screw rod 402 and the I-beam 301, and the sliding connection between the limit rod 403 and the I-beam 301, the I-beam 301 moves along the direction of the slide groove 401.
