Description

TECHNICAL FIELD

[0002] The automobile transmission main shaft is a key component in the automobile transmission system, responsible for transmitting power from the engine to the wheels through the transmission. It is usually composed of a shaft tube, an expansion sleeve and a universal joint, among which the universal joint is used to connect shafts of different axes to adapt to the angle changes during vehicle driving.

[0003] In the existing machining process of the automobile transmission main shaft, a laser cutting machine is usually used. The traditional laser cutting machine has some shortcomings: when the main shaft is fixed and supported, the traditional equipment usually adopts simple mechanical clamps or fixing devices. These methods are prone to looseness after a long time of work, which causes the main shaft to shift or shake during the machining process, thereby affecting the machining precision. For the main shaft end part with a complex geometric shape, such as a part with a bevel, a curved surface or multiple characteristic surfaces, due to the long length of the automobile transmission main shaft, the traditional equipment is difficult to achieve precise cutting at multiple angles, and multiple clamping and adjustment are usually required, which increases the error accumulation and machining time. During the machining process, the stability of the main shaft is the key to guarantee high-precision cutting. During the turnover or movement, the main shaft is prone to looseness or slippage, which affects the machining quality. SUMMARY

[0015] Compared with the prior art, the present application has the following beneficial effects:

[0016] 1、The application makes the plurality of guide rods gradually move to the center of the fixed ring table, thereby driving the plurality of sliding plates to gradually move to the center of the fixed ring table. The plurality of sliding plates drive the plurality of fixed plates and support wheels to move when moving, so that the plurality of support wheels gradually fit the outer wall of the main shaft. The edges of the plurality of support wheels are arc-shaped, so that the plurality of support wheels fit the main shaft, thereby supporting and fixing the main shaft. It is convenient for the five-axis cutting head to start cutting the main shaft, so that the anti-skid pad keeps fitting the main shaft. The plurality of anti-skid pads are in close contact with the main shaft, thereby constructing a stable support structure. Since the main shaft remains stationary, this close contact can ensure that the main shaft does not displace or shake during laser cutting, thereby providing a solid foundation for high-precision cutting. At the same time, the plurality of springs are compressed with the plurality of sliding rods, thereby achieving precise buffer alignment. This alignment method helps to ensure that the relative position between the main shaft and the five-axis cutting head always remains stable, reducing cutting errors caused by positional deviations. At the same time, the plurality of anti-skid pads increase the friction force on the main shaft, preventing the main shaft from deviating and rolling during processing.

[0017] 2、The application makes the back end of the moving table lift upward, thereby turning the support table and the main shaft upward. Since the top of the workbench is sunken, it is convenient for the main shaft to deflect, so that the end of the main shaft rises, and the five-axis cutting head processes the end of the main shaft. When cutting and processing the end of the main shaft, since the main shaft can be turned, multi-angle cutting can be achieved. By precisely controlling the turning angle of the main shaft, the end of the main shaft can be cut on different planes. For example, it can be cut on a horizontal plane first, then turned at a certain angle to cut on an inclined plane, and then turned to another angle for supplementary cutting. In this way, complex cutting shapes can be completed at one time, reducing the accumulation of errors caused by multiple clamping and adjustment, and improving cutting precision. For some main shaft ends with complex geometric shapes, such as parts with bevels, curved surfaces or multiple characteristic surfaces, the main shaft turning function can ensure that the laser beam always shines on the cutting part at the right angle, achieving precise cutting.

[0018] 3、The application makes the threaded rod move horizontally when rotating, so that the threaded rod drives the lower support plate and the support sleeve to move, thereby adjusting the position of the support sleeve. The support sleeve can support the bottom end of the main shaft to prevent it from slipping when lifted, thereby improving the stability of the main shaft. The movement of the support sleeve can support the bottom end of the main shaft, thereby adjusting the position of the main shaft inside the limiting component, facilitating the adjustment of the fixed area of the main shaft, and facilitating processing.

[0038] The plurality of slide plates 19 are internally provided with anti-skid assemblies for preventing the main shaft from rolling, the anti-skid assemblies comprising slide rods 22 and anti-skid pads 23, the plurality of slide rods 22 being respectively slidably connected inside the plurality of slide plates 19, the plurality of anti-skid pads 23 being respectively fixedly connected to the bottom ends of the plurality of slide rods 22, the bottom of each of the plurality of slide plates 19 being fixedly connected with a fixed plate 20, the two sides of each of the plurality of fixed plates 20 being provided with grooves matched with the anti-skid pads 23, one end of each of the plurality of slide rods 22 towards the inside of the slide plate 19 being fixedly connected with a spring 24, the other end of each of the plurality of springs 24 being respectively fixedly connected with the plurality of slide plates 19, the two sides of the inside of each of the plurality of slide plates 19 being provided with slide cavities 25, a plurality of through holes being annularly arranged inside each of the plurality of slide cavities 25, a piston plate 26 being slidably connected inside each of the plurality of slide cavities 25, each of the plurality of piston plates 26 being fixedly connected with a moving rod 27, each of the plurality of moving rods 27 penetrating through and being slidably connected with the plurality of slide plates 19, one end of each of the plurality of moving rods 27 extending to the outside of the slide plate 19 being fixedly connected with a fixed block 28, each of the plurality of fixed blocks 28 being fixedly connected to the two sides of each of the plurality of anti-skid pads 23, the damping effect being formed by the sliding of the piston plate 26 inside the slide cavity 25, so as to buffer the slide rod 22 and the anti-skid pad 23 in cooperation with the spring 24.

[0039] The support ring 17 is internally provided with a support assembly for supporting the end of the main shaft, the support assembly comprising a limiting rotating cylinder 41, a threaded rod 43, a lower support plate 46, a support sleeve 47 and a threaded sleeve 54, the limiting rotating cylinder 41 being integrally formed with horizontal plates on the two sides of the inside, the threaded rod 43 being provided with limiting grooves on the two sides, the two horizontal plates being respectively slidably connected inside the two limiting grooves and being matched with the two limiting grooves, the threaded sleeve 54 being fixedly connected to the rear side of the support ring 17, the threaded rod 43 penetrating through and being threadedly connected with the threaded sleeve 54, the threaded rod 43 being rotatably connected with an upper support plate 44 at the rear end, the upper support plate 44 being fixedly connected with limiting rods 45 on the two sides, the two limiting rods 45 being respectively fixedly connected with the two lower support plates 46 away from the upper support plate 44, the support sleeve 47 being fixedly connected to one side of the lower support plate 46, the threaded rod 43 being rotatably connected with the lower support plate 46 at the bottom and the front end, a second reversible motor 49 being fixedly connected to one side of the top of the moving table 15, a guide gear 50 being fixedly connected to the output end of the second reversible motor 49, a transmission gear 48 being fixedly connected to one end of the limiting rotating cylinder 41, the guide gear 50 being meshingly connected with the transmission gear 48, driving the limiting rotating cylinder 41 to rotate, so as to drive the threaded rod 43 to synchronously rotate.

[0040] In use, the automobile transmission main shaft is inserted through the support ring 17, and one end of the main shaft is placed inside the support sleeve 47. The first reversible motor 40 is started to drive the worm 39 to rotate, and the worm 39 drives the worm gear 37 to rotate. The worm gear 37 drives the rotating rod 35 to rotate, and the rotating rod 35 drives the two limiting gears 36 at both ends to rotate during rotation. The two limiting gears 36 drive the two guide plates 31 to rotate synchronously. When the two guide plates 31 rotate, the multiple guide grooves 32 inside them rotate. Because the trajectory of the multiple guide grooves 32 is gradually shrinking from the outside to the inside, the multiple guide grooves 32 limit and guide the multiple guide rods 29, causing the multiple guide rods 29 to gradually move towards the center of the fixed ring table 18, thereby driving the multiple sliding plates 19 to gradually move towards the center of the fixed ring table 18. The multiple sliding plates 19 drive the multiple fixed plates 20 and support wheels 21 to move, causing the multiple support wheels 21 to gradually fit the outer wall of the main shaft. The edges of the multiple support wheels 21 are arc-shaped, allowing the multiple support wheels 21 to fit the main shaft and thereby support and fix the main shaft, facilitating the activation of the five-axis cutting head 53 to cut the main shaft.

[0041] Before the multiple support wheels 21 approach the main shaft, the multiple anti-skid pads 23 will first contact the main shaft. After the multiple anti-skid pads 23 contact the main shaft, the multiple sliding plates 19 are still moving, causing the multiple anti-skid pads 23 to push the multiple sliding rods 22 to slide inside the multiple sliding plates 19. The multiple sliding rods 22 push and compress the multiple springs 24. At the same time, the anti-skid pads 23 move, causing the fixed blocks 28 on both sides to move, which in turn causes the moving rods 27 to move, thereby causing the two piston plates 26 to move, and the two piston plates 26 to slide inside the sliding cavity 25. The sliding cavity 25 can be filled with a buffer liquid, which flows through the multiple through holes when the piston plates 26 move inside the sliding cavity 25, improving the damping effect and buffering the sliding rods 22 with the springs 24, so that the anti-skid pads 23 remain in close contact with the main shaft. The multiple anti-skid pads 23 are in close contact with the main shaft, forming a stable support structure. Since the main shaft remains stationary, this close contact ensures that the main shaft does not shift or wobble during laser cutting, thereby providing a solid foundation for high-precision cutting. At the same time, the multiple springs 24 are compressed with the multiple sliding rods 22, achieving precise alignment. This alignment helps to ensure that the relative position between the main shaft and the five-axis cutting head 53 remains stable at all times, reducing cutting errors caused by positional deviations. At the same time, the multiple anti-skid pads 23 increase the friction on the main shaft, preventing the main shaft from shifting and rolling during processing.

[0042] Two hydraulic cylinders 12 are activated, causing the two connecting plates 14 to move. These connecting plates then push two push rods 13 forward, causing the push rods 13 to rotate the two upper L-shaped plates 11. The upper L-shaped plates 11 then rotate the two hinged plates 9 around the pivot 8, raising the rear end of the moving table 15 and rotating the support table 16 and the spindle upwards. Because the top of the worktable 2 is recessed, it facilitates spindle deflection, allowing the spindle end to rise and be processed by the five-axis cutting head 53. During cutting at the spindle end, the spindle's ability to rotate enables multi-angle cutting. By precisely controlling the spindle's rotation angle, cutting can be performed on different planes. For example, cutting can be done first on a horizontal plane, then rotated at a certain angle to cut on an inclined plane, and then rotated to another angle for further cutting. This allows for the completion of complex cutting shapes in one operation, reducing the accumulation of errors from multiple clamping and adjustments and improving cutting accuracy. For spindle ends with complex geometries, such as parts with bevels, curved surfaces, or multiple feature surfaces, the spindle flipping function can ensure that the laser beam always illuminates the part to be cut at the appropriate angle, achieving precise cutting.

[0043] The second forward and reverse motor 49 is started, causing the guide gear 50 to rotate. When the guide gear 50 rotates, it drives the transmission gear 48 and the limiting cylinder 41 to rotate. The horizontal plates on both sides of the limiting cylinder 41 limit the limiting grooves on both sides of the threaded rod 43, thereby driving the threaded rod 43 to rotate synchronously. Because the threaded rod 43 is threadedly connected to the threaded sleeve 54, the threaded rod 43 moves horizontally when rotating, causing the threaded rod 43 to drive the lower support plate 46 and the support sleeve 47 to move, thereby adjusting the position of the support sleeve 47. The support sleeve 47 can support the bottom end of the spindle, preventing the spindle from loosening and slipping when it is lifted, thus improving the stability of the spindle. When the limiting component is used to release the spindle, the movement of the support sleeve 47 can support the bottom end of the spindle, thereby adjusting the position of the spindle inside the limiting component, which facilitates the adjustment of the fixed area of ​​the spindle and makes it easier to process.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
