DETAILED DESCRIPTION

[0037] 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, rather than all the embodiments.

[0038] Example 1: This example provides a high-precision orthopedic tool for aviation cylindrical parts, see Figures 1-9 Specifically, it includes a bottom plate 100, which serves as the basic tooling component, and the bottom legs are used to support the overall structure; a fixed shaft 103 is rotatably inserted on the top surface to provide an installation foundation and rotation support for the gear plate 104 and subsequent components. Legs are fixed at the four corners of the bottom surface of the bottom plate 100, and a pair of fixed shafts 103 distributed throughout the top surface of the bottom plate 100 are rotatably inserted. The fixed shaft 103 penetrates the bottom plate 100, and the top end is fixedly connected to the gear plate 104. When driven by power, it rotates, driving the gear plate 104 and the connected structure to move, thereby adjusting the spacing of the rectangular frame. The top end of each fixed shaft 103 is sleeved with a concentrically fixed gear plate 104, and a pair of gear plates 104 are meshed and connected. Power is transmitted through the fixed shaft 103, so that the two gear plates 104 rotate in opposite directions, providing a power source for the translation of the first frame 200;

[0039] A first frame 200 is provided above each gear plate 104, and a second frame 202 is provided above each first frame 200 in parallel. A vertically distributed side frame 201 is fixed between the front and rear ends of the first frame 200 and the second frame 202 on the same side. The first frame 200, the second frame 202, and the pair of side frames 201 on the same side together form a rectangular frame for positioning and clamping the cylindrical member 110. The first frame 200 is also connected to the drive mechanism and the first crushing wheel 304 and other components. The cylindrical member 110 is placed between the pair of rectangular frames.

[0040] A pair of symmetrically distributed first support plates 204 are fixed to the front and rear sides of the top surface of the first frame 200. A first orthopedic block 206 is mounted on each of the first support plates 204. The inner arc surface of each first orthopedic block 206 slides against the outer surface of the cylindrical member 110. The first support plates 204 fix the first orthopedic block 206. The inner arc surface of the first orthopedic block 206 contacts the outer surface of the cylindrical member 110. When external force is applied during correction, the first slot 205 cooperates with the flat pin hole 2061, allowing the first orthopedic block 206 to deform and rotate along with the cylindrical member 110.

[0041] A bending bracket 208 is fixedly provided at the middle part of the inner side wall of the second frame 202. A hydraulic jack 209 with its telescopic end facing downward is installed at the bottom end of the bending bracket 208. A second support plate 210 is fixedly provided at the end of the telescopic rod of the hydraulic jack 209. A second orthopedic block 211 is fixedly provided on the bottom surface of the second support plate 210. The outer arc surface of the second orthopedic block 211 slides against the inner surface of the cylindrical member 110. The hydraulic jack 209 is extended and retracted to drive the second support plate 210 and the second orthopedic block 211 to move up and down. The outer arc surface of the second orthopedic block 211 contacts the inner surface of the cylindrical member 110, and cooperates with the first orthopedic block 206 to complete the correction.

[0042] A first connecting shaft 303 is rotatably inserted in the middle of the top surface of the first frame 200. A first rolling wheel 304 is concentrically fixedly sleeved on the inner end of the first connecting shaft 303. A second rolling wheel 310 is provided above the first rolling wheel 304. The second rolling wheel 310 and the first rolling wheel 304 on the same side respectively abut against the inner and outer sides of the bottom edge of the cylindrical member 110, and the first frame 200 is connected to the second rolling wheel 310 and the first rolling wheel 304 on the same side through a driving mechanism.

[0043] The outer surfaces of the first rolling wheel 304 and the second rolling wheel 310 are provided with a plurality of transverse grooves and longitudinal grooves, and the plurality of transverse grooves intersect perpendicularly with the longitudinal grooves. The second rolling wheel 310 and the first rolling wheel 304 are respectively pressed against the inner and outer sides of the bottom edge of the cylindrical part 110. The surface grooves increase the friction force, and they rotate relative to each other under the drive mechanism, driving the cylindrical part 110 to rotate and correct the shape.

[0044] It should be noted that in this embodiment, a first slot 205 is formed on the first support plate 204. The inner groove surface of the first slot 205 is arc-shaped. In order to allow the first orthopedic block 206 to rotate angularly as the cylindrical member 110 deforms during correction, a flat pin hole 2061 is formed in the middle of the first orthopedic block 206. A fixed pin shaft 2062 is slidably inserted into the flat pin hole 2061 and is distributed throughout. The two ends of the fixed pin shaft 2062 are fixedly inserted into the inner wall of the first slot 205.

[0045] A pair of pads 203 are provided between the first support plate 204 and the side frame 201 located on the same side. According to the increase or decrease in the diameter of the cylindrical part 110, the internal space of the rectangular frame is adjusted to adapt to cylindrical parts 110 of different specifications. The inner walls of the first frame 200 and the second frame 202 located on the same side are respectively provided with a first card slot and a second card slot. A steel ruler 207 is provided between the first frame 200 and the second frame 202. The upper and lower ends of the steel ruler 207 are fixedly engaged in the second card slot and the first card slot respectively. The steel ruler 207 is engaged in the card slots of the first frame 200 and the second frame 202 for measuring and controlling the orthopedic size of the cylindrical part 110 to ensure the orthopedic accuracy.

[0046] The working principle of this embodiment is as follows: First, according to the actual length of the cylindrical member 110 to be corrected, the fixed shaft 103 on the base plate 100 is rotated, and the first frame 200 is driven to translate by the mutually meshing gear plates 104, thereby flexibly adjusting the distance between the pair of rectangular frames (composed of the first frame 200, the second frame 202, and the side frames 201);

[0047] Then, the cylindrical member 110 is stably placed between the pair of rectangular frames, and the fixed shaft 103 is rotated again to shorten the distance between the rectangular frames until the bottom of the outer surface of the cylindrical member 110 is in close contact with the four first orthopedic blocks 206. At the same time, the two pairs of first rolling wheels 304 and second rolling wheels 310, which are located on the inner and outer sides of the bottom edge of the cylindrical member 110, are precisely pressed against the cylindrical member 110.

[0048] Next, the hydraulic jack 209 installed at the bottom end of the bending bracket 208 is activated, and its telescopic end drives the second support plate 210 and the second orthopedic block 211 to move downward until the outer arc surface of the second orthopedic block 211 slides and fits with the inner surface of the cylindrical member 110;

[0049] At this time, the first frame 200 activates the first and second rolling wheels 304 and 310 through the driving mechanism, driving the cylindrical member 110 to start rotating. During the rotation process, the first correction block 206, with the help of the arc-shaped first slot 205 and the fixing pin 2062 on the first support plate 204, can rotate along with the deformation of the cylindrical member 110, and cooperate with the second correction block 211 to perform all-round correction on the cylindrical member 110.

[0050] At the same time, the steel ruler 207 fixed in the slot of the first frame 200 and the second frame 202 accurately controls the correction size in real time to ensure the correction accuracy; and the pad 203 can be flexibly increased or decreased according to the diameter of the cylindrical part 110 to adapt to the correction needs of cylindrical parts 110 of different specifications.

[0051] Example 2: Based on Example 1, this example solves the problem of inconvenient spacing adjustment between a pair of rectangular frames by adding a limiting connecting plate 108 and a limiting pin 105, and further includes:

[0052] In the specific implementation process, Figure 3 and Figure 4 As shown, a pair of parallel I-shaped rails 101 are fixed on the front and rear sides of the top surface of the bottom plate 100, and U-shaped sliders 102 are fixed on the front and rear sides of the bottom surface of each first frame 200. Each U-shaped slider 102 is slidably engaged with the I-shaped rail 101 on the same side. The I-shaped rail 101 is fixed to the bottom plate 100, and the U-shaped slider 102 is installed on the bottom surface of the first frame 200. The two cooperate to provide guidance and sliding support for the translation of the first frame 200.

[0053] A limiting connecting plate 108 is fixed to the bottom surface of the first frame 200. An elliptical pin hole is formed on the limiting connecting plate 108. An eccentrically distributed limiting pin 105 is fixed to the gear plate 104. The top end of the limiting pin 105 is slidably inserted into the elliptical pin hole on the same side. When the gear plate 104 rotates, the limiting pin 105 slides in the elliptical pin hole of the limiting connecting plate 108. Through the limiting action, the rotation of the gear plate 104 is converted into a linear translation of the first frame 200.

[0054] A first rectangular frame 109 is fixed to the right side wall of the base plate 100, and a first motor 106 with the output end facing downward is installed inside the first rectangular frame 109. The end of the motor shaft of the first motor 106 is sleeved with a concentrically fixed small-diameter pulley, and the bottom end of the fixed shaft 103 located on the right side extends downward and is sleeved with a concentrically fixed large-diameter pulley. The small-diameter pulley is connected to the large-diameter pulley through a drive belt 107. The first motor 106 provides power, and the power is transmitted to the fixed shaft 103 through the belt transmission system to realize automatic spacing adjustment.

[0055] The working principle of this embodiment is as follows: when the first motor 106 is started, its motor shaft drives the small-diameter pulley to rotate synchronously, and the small-diameter pulley is driven by the driving belt 107, which drives the large-diameter pulley to rotate, thereby rotating the fixed shaft 103 and the gear plate 104 which are concentrically fixed to the large-diameter pulley;

[0056] Since the two gear plates 104 are meshed with each other, the rotation of one gear plate 104 drives the other gear plate 104 to rotate in the opposite direction. During the rotation of the gear plates 104, the eccentrically arranged limit pin 105 moves accordingly, and its top end slides in the elliptical pin hole of the limit connecting plate 108;

[0057] The limiting effect formed by the elliptical pin hole and the limiting pin shaft 105 drives the first frame 200 and the U-shaped slider 102 at the bottom through the limiting connecting plate 108 to slide back and forth along the I-shaped slide rail 101, ultimately achieving automatic adjustment of the spacing between a pair of rectangular frames.

[0058] Embodiment 3: Based on the embodiment 2, this embodiment realizes adaptive correction molding of cylindrical parts 110 with different wall thicknesses, solves the problem of poor versatility of traditional correction equipment and the need for frequent mold replacement, and also includes:

[0059] In the specific implementation process, Figure 6 and Figure 8 As shown, a fixed ear seat 306 is fixed to the outer side surface of the bending part of the bending bracket 208, and an electric telescopic cylinder 307 with the telescopic end facing downward is installed on the outer end of the fixed ear seat 306. An L-shaped connecting plate 308 is fixed to the end of the telescopic rod of the electric telescopic cylinder 307. A second connecting shaft 309 is rotatably inserted into the bottom end of the L-shaped connecting plate 308 and is distributed throughout. The electric telescopic cylinder 307 adjusts the extension and contraction according to the wall thickness of the cylindrical member 110, and drives the second connecting shaft 309 and the second rolling wheel 310 to move up and down through the L-shaped connecting plate 308 to adjust the spacing between the second rolling wheels 310.

[0060] The inner end of the second connecting shaft 309 is fixedly inserted in the middle of the second rolling wheel 310. The outer end of the second connecting shaft 309 is sleeved with a concentrically fixed second rotary disc 311. The outer end of the first connecting shaft 303 is sleeved with a concentrically fixed first rotary disc 305. The first rotary disc 305 and the second rotary disc 311 are staggered.

[0061] The driving mechanism includes a worm 302, a first pin 312, and a second pin 313. A second rectangular frame 300 is fixedly provided on the top surface of the first frame 200. A second motor 301 is installed inside the second rectangular frame 300. A spirally distributed worm 302 is fixedly provided at the end of the motor shaft of the second motor 301. The second motor 301 drives the worm 302 to rotate. The worm 302 engages with the staggered first and second pins 312, 313, driving the first and second rotating disks 305, 311 to rotate in opposite directions, thereby causing the first and second rolling wheels 304, 310 to rotate relative to each other.

[0062] A plurality of first pins 312 are fixedly disposed on the inner side of the first rotating disk 305 and a plurality of second pins 313 are fixedly disposed on the outer side of the second rotating disk 311. The first pins 312 and the second pins 313 are alternately disposed on both sides of the worm 302 and meshed with the worm 302.

[0063] The first pin 312 is always in meshing engagement with the helical teeth of the worm 302. Since the second pin 313 can be raised and lowered within a small range, the tooth width of the helical teeth of the worm 302 is kept within a reasonable range to avoid interference.

[0064] The working principle of this embodiment is as follows: according to the actual wall thickness of the cylindrical member 110, the electric telescopic cylinder 307 is activated, and its telescopic rod drives the L-shaped connecting plate 308 and the second connecting shaft 309 connected thereto, the second rolling wheel 310 and the second rotating disk 311 to move downward in a translational manner until the second rolling wheel 310 abuts against the inner surface of the cylindrical member 110. At this time, the bottom of the outer surface of the cylindrical member 110 maintains contact with the first rolling wheel 304.

[0065] After the second motor 301 is started, its motor shaft drives the worm 302 to rotate synchronously. Since the worm 302 is engaged with the first pin 312 on the first rotary disk 305 and the second pin 313 on the second rotary disk 311, and the first pin 312 and the second pin 313 are staggered on both sides of the worm 302, the rotation of the worm 302 will simultaneously drive the first rotary disk 305 and the second rotary disk 311 to rotate in opposite directions.

[0066] The first turntable 305 drives the first rolling wheel 304 to rotate forward through the first connecting shaft 303, and the second turntable 311 drives the second rolling wheel 310 to rotate reversely through the second connecting shaft 309. Under the action of this pair of relatively rotating rolling wheels, the cylindrical part 110 is driven to rotate, and the correction and forming processing of the cylindrical part 110 is realized through the synchronous action of the second rolling wheel 310 and the first rolling wheel 304 on the inner and outer surfaces of the cylindrical part 110.

[0067] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
