Description

Technical Field

[0001] The present invention relates to the field of metal turning, in particular to a turning device for producing automobile parts. Background Art

[0002] A large portion of the important parts of automobiles are made of metal materials. Among them, the drive shaft, which is an important power component, is generally made of steel or aluminum alloy and is usually processed from metal rollers. In order to meet the needs of automobile assembly and perform certain strength optimization, the metal shaft rollers must be beveled.

[0003] However, the existing device is prone to stress deformation during turning because the shaft roller is too long and has a single fulcrum. It is not convenient to adjust the shaft roller position in real time and judge whether the adjustment is in place. It is also not convenient to judge in advance whether the shaft roller will deflect during rotation, which easily causes the shaft roller processing to be scrapped. Summary of the Invention

[0006] Furthermore, the auxiliary mechanism includes a support frame, which is fixedly connected to the support base, and two sliding frames are slidably connected to the support frame, and two wheel frames are slidably connected to the two sliding frames, and rubber wheels are provided on the wheel frames, and a connecting spring is connected between the two wheel frames, and one side of the two sliding frames is fixedly connected to a connecting plate, and a threaded column is threadedly connected between the two connecting plates, and the thread directions of the two parts on the threaded column are opposite, and a worm gear is fixedly connected to the threaded column, and a vertical rod is fixedly connected to the support base, and a servo motor is fixedly connected to the vertical rod, and a worm is fixedly connected to the transmission shaft of the servo motor, and the worm gear is meshed with the worm gear, and a top rod is fixedly connected to one of the connecting plates, and a pressure sensor is fixedly connected to the other connecting plate, and the pressure sensor is connected to the servo motor via a wire.

[0007] Furthermore, the knife moving mechanism includes two guide plates, both of which are fixedly connected to the supporting base plate, and guide grooves are provided on the guide plates. A movable platform is slidably connected between the four limiting columns, and both sides of the movable platform are respectively located in the guide grooves of the two guide plates, and a knife head is fixedly connected to the movable platform.

[0008] Furthermore, it also includes an indicating mechanism, which is arranged on the supporting frame, and is used to indicate whether the automobile transmission shaft roller is placed accurately, and the indicating mechanism includes a side plate, which is fixedly connected to the upper part of the supporting frame, and a sliding platform is slidably connected to the side plate, and a stopper is fixedly connected to the side plate, and the lower part of the sliding platform is rotatably connected to a swing frame, and the lower part of the swing frame is rotatably connected to two contact wheels, and a friction wheel 1 is fixedly connected to the swing frame rotating shaft, and a friction wheel 2 is rotatably connected to the lower part of the sliding platform, and a torsion spring is connected between the friction wheel 2 and the sliding platform, and the friction wheel 2 is rotatably connected to the contact wheel. The friction wheel 1 is in contact with the friction wheel 2, and the friction wheel 1 is larger than the friction wheel 2. The friction wheel 2 is fixedly connected to a swing rod, and the lower part of the swing rod is fixedly connected to a plane reflector. The support base is fixedly connected to a photoelectric reflection sensor, and a display screen is provided on the upper part of the photoelectric reflection sensor. The display screen and the photoelectric reflection sensor are connected by a wire. Each side of the sliding frame is fixedly connected to a limit straight rod, and each limit straight rod is rotatably connected to a threaded adjustment rod. Each threaded adjustment rod is threadedly connected to two movable levers, and the limit straight rod passes through the movable lever, and the two sections of thread on the threaded adjustment rod are opposite.

[0009] The cam is connected with the two guide wheels, and the two guide wheels are connected with each other in a fixed manner, wherein the two guide wheels are connected with each other in a fixed manner.

[0010] The beneficial effects are: 1. The two sliding frames will drive the wheel frame to clamp the side of the shaft roller, and then tighten the three-jaw chuck so that the three-jaw chuck fixes one end of the shaft roller to complete the clamping. This provides the shaft roller with an additional fulcrum during processing, and it is not easy to deform during the turning process due to the shaft roller being too long.

[0011] 2. When the shaft roller is tilted, the two contact wheels are in contact with the surface of the shaft roller, and the two contact wheels and the swing frame will also tilt. The tilt of the swing frame will drive the friction wheel 1 to rotate a certain angle, and then drive the friction wheel 2 to rotate a certain angle. The torsion spring is twisted, and then the rotation of the friction wheel 2 will drive the swing rod to swing a certain angle. The swinging of the swing rod will make the plane reflector no longer in a vertical state, and then make the photoelectric reflection sensor in an untriggered state. The photoelectric reflection sensor is not triggered and the display screen will go out. In this way, the operator can observe the state of the display screen and continuously adjust the position of the shaft roller when fixing the shaft roller with a three-jaw chuck. Finally, the display screen is always on after the shaft roller is fixed, so that the position of the shaft roller does not tilt when it is placed and fixed, which is more stable when the shaft roller rotates. Since the friction wheel 2 is smaller than the friction wheel 1, and under the lever magnification effect of the swing rod, the tilt angle of the shaft roller can be magnified, so that the slight tilt of the shaft roller can also be easily read.

[0012] 3. When the pressure sensor is triggered, the pressure sensor will also control the electric slider to move upward and then reset downward once. The movement of the electric slider will drive the moving rack to move. The movement of the moving rack will engage with the rotating gear that swings with the clamping frame, and drive the rotating gear to rotate. The rotation of the rotating gear will drive one of the limiting wheels to rotate, and the rotation of the limiting wheel will drive the shaft roller to rotate. In this way, the shaft roller is rotated before being fixed, so that the operator can judge in advance whether the shaft roller will deflect after the subsequent fixed rotation through the status of the display screen when the shaft roller is rotating. This will prevent the shaft roller from being scrapped due to improper fixation during turning. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention will be described in detail below with reference to the accompanying drawings.

[0024] Example 1 A turning device for producing automobile parts, such as Figure 1-9 As shown, it includes a driving motor 1, and a three-jaw chuck 2 is provided on the output shaft of the driving motor 1, and the three-jaw chuck 2 is used to clamp the automobile transmission shaft roller. The lower part of the driving motor 1 is fixedly connected to a support base plate 3, and a slide rail 41 is fixedly connected to the support base plate 3. An electric slide 42 is slidably connected to the slide rail 41, and four limiting columns 43 are fixedly connected to the electric slide 42. An auxiliary mechanism is provided on the supporting base plate 3, and the auxiliary mechanism is used to assist turning. A tool moving mechanism is provided on the limiting column 43, and the tool moving mechanism is used to automatically move the tool head 64 for turning.

[0025] The auxiliary mechanism includes a support frame 51, which is fixedly connected to the support base 3. Two sliding frames 52 are slidably connected to the support frame 51. Two sliding frames 52 are slidably connected to two wheel frames 53. Rubber wheels are provided on the wheel frames 53. A connecting spring 521 is connected between the two wheel frames 53. One side of the two sliding frames 52 is fixedly connected to a connecting plate 54. A threaded column 55 is connected between the two connecting plates 54 by a thread. The two parts of the threaded column 55 are fixedly connected to the support base 3. The thread directions are opposite, and a worm gear 56 is fixedly connected to the threaded column 55, a vertical rod 57 is fixedly connected to the support base plate 3, a servo motor 58 is fixedly connected to the vertical rod 57, a worm 59 is fixedly connected to the transmission shaft of the servo motor 58, and the worm 59 is engaged with the worm gear 56. A top rod 510 is fixedly connected to one of the connecting plates 54, and a pressure sensor 511 is fixedly connected to the other connecting plate 54. The pressure sensor 511 is connected to the servo motor 58 through a wire.

[0026] The knife moving mechanism includes two guide plates 62, both of which are fixedly connected to the supporting base plate 3. A guide groove is provided on the guide plate 62. A movable platform 63 is slidably connected between the four limiting columns 43. Both sides of the movable platform 63 are respectively located in the guide grooves of the two guide plates 62, and a cutter head 64 is fixedly connected to the movable platform 63.

[0027] In actual work, the transmission shaft of the automobile is processed from a shaft roller. For subsequent assembly, the cross-section of the transmission shaft needs to be beveled. First, the operator places one end of the shaft roller in a horizontal posture in the three-jaw chuck 2, and then the operator starts the servo motor 58. After the servo motor 58 is started, it will drive the worm 59 to rotate. The rotation of the worm 59 will drive the threaded column 55 to rotate through the worm gear 56. The rotation of the threaded column 55 will drive the two connecting plates 54 to move toward each other through the two opposite threads. The movement of the two connecting plates 54 will drive the two sliding frames 52 to move toward each other together, and then the two sliding frames 52 will drive the wheel frame 53 to clamp the side of the shaft roller. When clamping, the two wheel frames 53 will further move horizontally in opposite directions for a certain distance, and the connecting spring 521 will be stretched, and then tightened. Tighten the three-jaw chuck 2 so that the three-jaw chuck 2 fixes one end of the shaft roller to complete the clamping. This provides the shaft roller with an additional fulcrum during processing, and is less likely to be deformed during the turning process due to the shaft roller being too long. The two connecting plates 54 will also drive the push rod 510 and the pressure sensor 511 to move towards each other. Then, when the two sliding frames 52 clamp the shaft roller, the pressure sensor 511 will be squeezed by the push rod 510 and triggered. The triggering of the pressure sensor 511 will control the servo motor 58 to stop rotating. Then the operator starts the drive motor 1 first. The drive motor 1 will drive the three-jaw chuck 2 and the shaft roller to rotate at high speed, and then start the electric slide 42. The electric slide 42 drives the cutter head 64 to move horizontally to turn the end face of the shaft roller. Under the guidance of the guide plate 62, the cutter head 64 will turn the end face of the shaft roller into a bevel.

[0028] Example 2 On the basis of Example 1, Figure 4-7As shown, an indicating mechanism is also included. The indicating mechanism 7 is arranged on the supporting frame 51. The indicating mechanism is used to indicate whether the automobile transmission shaft roller is placed accurately. The indicating mechanism includes a side plate 71. The side plate 71 is fixedly connected to the upper part of the supporting frame 51. A sliding platform 72 is slidably connected to the side plate 71. A stopper 73 is fixedly connected to the side plate 71. The lower part of the sliding platform 72 is rotatably connected to a swing frame 74. The lower part of the swing frame 74 is rotatably connected to two contact wheels 75. A friction wheel 1 76 is fixedly connected to the rotating shaft of the swing frame 74. The lower part of the sliding platform 72 is rotatably connected to a friction wheel 2 77. A torsion spring 78 is connected between the friction wheel 2 77 and the sliding platform 72. The friction wheel 2 77 is in contact with the friction wheel 1 76. The friction wheel 1 76 is larger than the friction wheel 2 77. The friction wheel 2 77 is fixedly connected to a swing rod 79. The lower part of the swing rod 79 is fixedly connected to a plane reflector 710. The support base 3 is fixedly connected to a photoelectric reflection sensor 711. A display screen 712 is provided on the upper part of the photoelectric reflection sensor 711. The display screen 712 is connected to the photoelectric reflection sensor 711 through a wire. Each side of the sliding frame 52 is fixedly connected to a limiting straight rod 713. Each limiting straight rod 713 is rotatably connected to a threaded adjustment rod 714. Each threaded adjustment rod 714 is threadedly connected to two moving levers 715. The limiting straight rod 713 passes through the moving lever 715, and the two sections of thread on the threaded adjustment rod 714 are opposite.

[0029] At first, the plane reflector 710 is in a vertical state, the photoelectric reflection sensor 711 is in a triggered state, and the reading of the display screen 712 is reset to zero. When the operator places the shaft roller horizontally in the three-jaw chuck 2, he first puts the side of the shaft roller between the two contact wheels 75, then squeezes the contact wheel 75 upward and drives the swing frame 74 and the sliding table 72 to move upward for a distance. After the sliding table 72 moves upward for a distance, the upper end of the sliding table 72 will be blocked by the stop block 73. Finally, the operator fixes one end of the shaft roller on the three-jaw chuck 2. When fixing the shaft roller, the operator can judge whether the position of the shaft roller is fixed in place by observing the reading of the display screen 712. When the shaft roller tilts, since the two contact wheels 75 are in contact with the surface of the shaft roller, the two contact wheels 75 and the swing frame 74 will also tilt. The tilt of the swing frame 74 will drive the friction wheel 1 76 to rotate a certain angle, and then drive the friction wheel 2 77 to rotate a certain angle. The torsion spring 78 is twisted, and then the friction wheel 2 77 The rotation will drive the swing rod 79 to swing a certain angle. The swing of the swing rod 79 will make the plane reflector 710 no longer in a vertical state, thereby causing the photoelectric reflection sensor 711 to measure the tilt angle of the plane reflector 710, and then display the reading on the display screen 712, so that the operator can observe the reading on the display screen 712 to determine the posture of the shaft roller. Initially, before adjustment, the moving lever 715 is farther away from the wheel frame 53, and then the upper and lower threaded adjustment rods 714 are rotated and adjusted respectively to drive the moving lever 715 to squeeze and adjust the distance between each group of two wheel frames 53, so that the posture of the shaft roller can be adjusted, and finally the display screen 712 reading is returned to zero after the shaft roller is fixed, so that the position of the shaft roller is not tilted when placed and fixed, so that the shaft roller is more stable when rotating. Since the friction wheel 2 77 is smaller than the friction wheel 1 76, and under the lever magnification effect of the swing rod 79, the tilt angle of the shaft roller can be magnified, so that the slight tilt of the shaft roller is also easy to read.

[0030] Example 3 On the basis of Example 2, Figure 8-9As shown, it also includes a toggle mechanism, which is arranged on the support base plate 3, and is used to drive the shaft roller to rotate when calibrating the shaft roller position. The toggle mechanism includes two support vertical plates 81, and the two support vertical plates 81 are fixedly connected to the support base plate 3. A baffle frame 82 is slidably connected to the upper part of one of the support vertical plates 81, and a return spring 83 is connected between the baffle frame 82 and the support vertical plate 81. One end of the baffle frame 82 is fixedly connected to a rack connecting rod 84, and two rotating rods 85 are rotatably connected between the two support vertical plates 81. The two rotating rods 85 are fixedly connected to a transmission gear 86. The transmission gears 86 are meshed, one end of one of the rotating rods 85 is fixedly connected to a driving gear 861, and the driving gear 861 is meshed with the rack connecting rod 84. The two rotating rods 85 are fixedly connected to a clamping frame 87, and each of the clamping frames 87 is rotatably connected to two limiting wheels 88, one of the limiting wheels 88 is fixedly connected to a rotating gear 89 on its side, a guide rail 810 is fixedly connected to the support base 3, and an electric slider 811 is slidably connected to the guide rail 810, the electric slider 811 is connected to the pressure sensor 511 through a wire, and a moving rack 812 is fixedly connected to the electric slider 811.

[0031] When the operator places the shaft roller, he uses the side of the shaft roller to squeeze the baffle frame 82 to move horizontally. The horizontal movement of the baffle frame 82 will drive the driving gear 861 to rotate, and then drive the two transmission gears 86 to rotate in the opposite direction, so that the two rotating rods 85 will rotate in opposite directions by a certain angle. The rotation of the two rotating rods 85 will drive the clamping frame 87 and the limiting wheel 88 to swing together. The two clamping frames 87 swinging in the direction of approaching each other will cause the four limiting wheels 88 to clamp the side of the shaft roller. Then the operator starts the servo motor 58 to drive the two sliding frames 52 and the wheel frame 53 to clamp the side of the shaft roller. When the pressure sensor 511 is triggered, the pressure sensor 511 will also Control the electric slider 811 to move upward and then reset downward once. The movement of the electric slider 811 will drive the moving rack 812 to move. The movement of the moving rack 812 will engage with the rotating gear 89 after swinging with the clamping frame 87, and drive the rotating gear 89 to rotate. The rotation of the rotating gear 89 will drive one of the limiting wheels 88 to rotate. The rotation of the limiting wheel 88 will then drive the shaft roller to rotate. In this way, the shaft roller is rotated before being fixed. The operator can judge in advance whether the shaft roller will deflect after the subsequent fixed rotation by the state of the display screen 712 when the shaft roller is rotating. This will prevent the shaft roller from being scrapped due to improper fixation during turning.
