Description

Technical Field

[0002] The drive shaft is an important component for transmitting power in the automobile transmission system. Its function is to transmit the power of the engine to the wheels together with the gearbox and drive axle to generate driving force for the car. The drive shaft is a high-speed, low-support rotating body, so its dynamic balance is crucial. Generally, the drive shaft must undergo a dynamic balance test before leaving the factory and be adjusted on a balancing machine.

DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] refer to Figures 1 to 13 The intelligent detection device for dynamic balancing of automobile transmission shafts shown in the figure comprises a dynamic balancing detection machine composed of a detection instrument 1 and a display 2, and also comprises a material discharge component, a material transfer component, a material blanking component and a docking component. The material discharge component and the docking component are respectively located on both sides of the material transfer component. The material blanking component is located beside the material transfer component and is used to collect transmission shafts that have passed the inspection. The material transfer component comprises two XY axis horizontal moving mechanisms spaced apart in the horizontal direction and a No. 1 clamping mechanism respectively arranged on the two XY axis horizontal moving mechanisms and capable of moving along the XY axis. Each No. 1 clamping mechanism has a A clamping jaw end flatly clamps one end of the rotating shaft and can drive the transmission shaft to rotate. A rotating mechanism is provided under each No. 1 clamping jaw mechanism to drive the corresponding clamping jaw end to rotate 90° along the Z axis each time. The discharge assembly, blanking assembly, docking assembly and dynamic balancing detection machine are distributed in a matrix around one of the No. 1 clamping jaw mechanisms, and the dynamic balancing detection machine is arranged between two XY-axis horizontal moving mechanisms. The discharge assembly includes a valve mechanism for discharging materials one by one, and the docking assembly includes a No. 2 clamping jaw mechanism 56 docking with the No. 1 clamping jaw mechanism, and the No. 2 clamping jaw mechanism 56 has the same structure as the No. 1 clamping jaw mechanism.

[0038] First, the transmission shaft to be tested is discharged one by one through the valve mechanism in the discharge assembly, and at the same time, the No. 1 clamping mechanism is horizontally moved to one side of the discharge assembly through the XY axis horizontal moving mechanism, and the clamping end on the No. 1 clamping mechanism clamps the transmission shaft on the discharge assembly, and then the No. 1 clamping mechanism is rotated 90° toward the dynamic balancing tester through the rotating mechanism, and the directions of the two No. 1 clamping mechanisms are adjusted through the two XY axis horizontal moving mechanisms so that the two No. 1 clamping mechanisms are located on the same horizontal line. When the No. 1 clamping mechanism that clamps the transmission shaft moves toward the dynamic balancing tester set between the two XY axis horizontal moving mechanisms, the transmission shaft will horizontally pass through the detection port on the detector 1 and the other No. 1 clamping mechanism. Mechanism docking, when the No. 1 clamping mechanism drives the transmission shaft to rotate, the detector 1 located between the transmission shafts will perform dynamic balancing detection on the rotating transmission shaft, and display the detection data in real time on the display 2 for the operator to observe. When the detection data meets the standards, the No. 1 clamping mechanism will transfer the qualified transmission shaft to the blanking assembly through the rotating mechanism and the XY-axis horizontal moving mechanism to complete the collection of qualified products. When the detection is unqualified, the No. 1 clamping mechanism will transfer the transmission shaft to the docking assembly and complete the docking with the No. 2 clamping mechanism 56, so that the transmission shaft can be rotatably fixed between the No. 1 clamping mechanism and the No. 2 clamping mechanism 56. At this time, the operator can manually weld the unqualified transmission shaft with the balancing sheet.

[0039] A horizontal workbench No. 1 3 is provided below the two XY-axis horizontal moving mechanisms, each of the XY-axis horizontal moving mechanisms is a horizontally arranged XY-axis slide 4, each XY-axis slide 4 is arranged on the top of the No. 1 workbench 3, and the two XY-axis slides 4 are distributed at intervals in the horizontal direction, and the two No. 1 clamping mechanisms are respectively arranged on the moving ends of the two XY-axis slides 4.

[0040] The XY-axis slide 4 is used to drive the horizontal displacement of the No. 1 clamping mechanism arranged thereon, so that the No. 1 clamping mechanism can be operated in multiple directions. The spaced distribution of the XY-axis slide 4 is used to place the dynamic balancing tester, so that one of the No. 1 clamping mechanisms can clamp the transmission shaft horizontally through the detection port of the detector 1 and dock with another clamping mechanism, thereby realizing the dynamic balancing test of the transmission shaft by the detector 1.

[0041] Each of the rotating mechanisms comprises:

[0042] Two brackets 5 fixedly arranged at the upper movable end of the corresponding XY-axis slide 4, each of the brackets 5 is composed of a horizontal support plate 6 and two vertical connecting plates 7 fixedly arranged vertically downward at both ends of the support plate 6, and the bottom of each vertical connecting plate 7 is fixedly connected to the upper movable end of the XY-axis slide 4;

[0043] Two horizontal and meshing gears 8, which are respectively located above the two brackets 5;

[0044] A first drive motor 9 is fixedly arranged at the bottom of one of the support plates 6 in a vertical state, and an output shaft of the first drive motor 9 vertically passes through the support plate 6 upward and is coaxially fixedly connected to one of the gears 8;

[0045] The bearing 10 is fixedly arranged in a horizontal state on the top of another support plate 6. A rotating shaft 11 which is horizontal and matched with the bearing 10 is coaxially arranged on the bearing 10. The other gear 8 is coaxially connected to the rotating shaft 11. A turntable 12 is coaxially fixedly arranged on the top of the rotating shaft 11. Each of the No. 1 clamping jaw mechanisms is arranged on the corresponding turntable 12.

[0046] When the No. 1 driving motor 9 is started, its output shaft will drive the rotation of one of the gears 8, thereby the other gear 8 will also rotate, and then the other gear 8 will drive the rotation of the rotating shaft 11 and the turntable 12 fixed thereto, and finally realize the effect of rotating the No. 1 clamping mechanism along the Z axis.

[0047] Each of the No. 1 clamping jaw mechanisms is a three-jaw chuck 13 in a horizontal state, and a vertical plate 14 is provided on the side of each of the three-jaw chuck 13. The lower end of each of the vertical plates 14 is fixedly set on the top of the corresponding turntable 12, and each three-jaw chuck 13 is set on one side of the corresponding vertical plate 14. A No. 2 drive motor 15 in a horizontal state is fixedly set on the other side of one of the vertical plates 14, and the output shaft of the No. 2 drive motor 15 horizontally passes through the vertical plate 14 and is coaxially fixed to the corresponding three-jaw chuck 13. A horizontal support shaft 16 is provided on the other vertical plate 14, and the other three-jaw chuck 13 is coaxially inserted on the support shaft 16. The two three-jaw chucks 13 are at the same height, and the three-jaw chuck 13 is the clamping jaw end of the above-mentioned No. 1 clamping jaw mechanism.

[0048] One of the three-jaw chucks 13 fixedly connected to the second drive motor 15 is used to drive the rotation of the three-jaw chuck 13, thereby driving the rotation of the transmission shaft, and the other three-jaw chuck 13 inserted on the support shaft 16 is used to connect with another three-jaw chuck 13, so that the transmission shaft can be fixed between the two three-jaw chucks 13 and realize rotation.

[0049] The rotating shaft 11 is provided with a spring 20 abutting mechanism 17, four proximity switches 18 distributed in a matrix are provided around one of the gears 8, the spring 20 abutting mechanism 17 comprises a cylindrical shell 19, a spring 20 and a movable pin 21, the cylindrical shell 19 is fixedly arranged on the top of the rotating shaft 11 in a horizontal state, one end of the cylindrical shell 19 is an open structure, and the other end is a closed structure, a mounting cover 22 is clamped on the opening structure of the cylindrical shell 19, the movable pin 21 is movably arranged in the cylindrical shell 19 in a horizontal state, and one end of the movable pin 21 is coaxially formed with a circle having the same diameter as the inner circle of the cylindrical shell 19 The annular flange 23 has the other end formed into a columnar body 24 with a diameter smaller than the inner diameter of the cylindrical shell 19. The columnar body 24 of the movable pin 21 horizontally passes through one end of the closed structure of the cylindrical shell 19 and extends to the outside of the cylindrical shell 19. The spring 20 is horizontally arranged in the cylindrical shell 19. One end of the spring 20 is in conflict with the mounting cover 22, and the other end is in conflict with the annular flange 23. The columnar body 24 of the movable pin 21 is arranged outwardly along the radial direction of the gear 8, and the end of the columnar body 24 is round. Each time the gear 8 rotates 90°, the columnar body 24 on the movable pin 21 conflicts with the corresponding proximity switch 18.

[0050] First of all, the above-mentioned movable pin 21 is similar to the piston in the hydraulic cylinder, and the spring 20 gives elastic force to the movable pin 21. The proximity switch 18 is electrically connected to the No. 1 drive motor 9 through the controller. The controller is not drawn in the figure. When the rotating shaft 11 rotates 90°, the spring 20 fixed thereon will rotate accordingly, so that when the column 24 of the movable pin 21 touches one of the proximity switches 18, the proximity switch 18 will turn off the No. 1 drive motor 9 through the controller. When the spring 20 resistance mechanism 17 rotates away from the proximity switch 18, the No. 1 motor will start again. Due to the guiding effect of the round head end of the column 24, the entire movable pin 21 moves in the cylindrical shell 19 and compresses the spring 20. Therefore, when the column 24 does not conflict with the proximity switch 18, the reset elastic force of the spring 20 will pop the movable pin 21 outward. Repeating the above steps can achieve a 90° limited rotation of the rotating mechanism.

[0051] The discharge assembly also includes:

[0052] A support frame 25 is arranged beside the first workbench 3;

[0055] First, place the transmission shaft to be tested in the loading hopper 26. The transmission shaft will fall one by one onto the drop plate 28 through the vertical drop channel 27 and be intercepted by the valve mechanism. Then, the valve mechanism is used to realize the one-by-one sliding of the transmission shaft on the drop plate 28. The two side baffles 29 are used to prevent the transmission shaft from falling from the drop plate 28 when it slides on the drop plate 28. The positive baffle 31 is used to block the transmission shaft sliding off the drop plate 28. The material removal notch 30 is used to prevent the three-jaw chuck 13 from clamping the transmission shaft blocked by the positive baffle 31.

The blocking rod 40 is fixedly provided on one side of the rectangular slider 34. 0 is consistent with the width direction of the drop plate 28, and a blocking rod 40 is fixedly provided with a first blocking block 41 which is tilted downward at one end of the blocking rod 40 facing the drop plate 28. The two rectangular sliders 34 are connected by a horizontal connecting rod 42, and the two ends of the connecting rod 42 are respectively fixedly connected to the two rectangular sliders 34, and the connecting rod 42 is located directly below the blocking rod 40. A second blocking block 43 which is tilted upward is fixedly provided at the middle end of the connecting rod 42, and the distance between the second blocking blocks 43 and the second blocking blocks 43 is a transmission shaft diameter. The middle part of the drop plate 28 is provided with a An avoidance groove 44 is provided for avoiding the upward and downward movement of the No. 1 blocking block 41 and the No. 2 blocking block 43. An L-shaped bracket 45 is fixedly provided on the side wall of the support stand 25 close to the rectangular sliding block 34. A horizontal plate 46 is fixedly provided on the top of the vertical end of the L-shaped bracket 45. A No. 3 driving motor 47 in a horizontal state is fixedly provided on the horizontal plate 46. The output shaft of the No. 3 driving motor 47 is arranged toward the rectangular sliding block 34, and a cam 48 in a vertical state is fixedly provided at the end of its output shaft, and one end of the cam 48 is fitted with the bottom of the corresponding rectangular sliding block 34.

[0057] When the No. 3 driving motor 47 is started, the cam 48 will rotate accordingly, so that the rectangular slider 34 that fits with the cam 48 will be driven by the cam 48 to move up and down on the limit block 32, and the block 33 is used to prevent the rectangular slider 34 from falling off the limit block 32 during movement. When one of the rectangular sliders 34 is driven to move up and down, the other rectangular slider 34 will also move up and down synchronously through the action of the connecting rod 42. At the same time, the No. 1 blocking block 41 and the No. 2 blocking block 43 will also move up and down. In the initial state, the No. 1 blocking block 41 blocks the transmission shaft on the drop plate 28 downward. When the No. 3 driving motor 47 is started, the cam 48 will rotate accordingly, so that the rectangular slider 34 that fits with the cam 48 will be driven by the cam 48 to move up and down on the limit block 32. The block 33 is used to prevent the rectangular slider 34 from falling off the limit block 32 during movement. When one of the rectangular sliders 34 is driven to move up and down, the other rectangular slider 34 will also move up and down synchronously through the action of the connecting rod 42. At the same time, the No. 1 blocking block 41 and the No. 2 blocking block 43 will also move up and down. In the initial state, the No. 1 blocking block 41 blocks the transmission shaft on the drop plate 28 downward. When the No. 3 driving motor 47 is started, the cam 48 will rotate accordingly. During startup, the upward movement of the No. 1 blocking block 41 causes the transmission shaft to lose resistance and slide from the drop plate 28 toward the positive baffle 31. At this time, the upward movement of the No. 2 blocking block 43 blocks the transmission shaft behind. The No. 3 driving motor 47 is a stepping motor, which stops each time it rotates 180°. Since the two rectangular sliders 34 are in an inclined state, there will be a certain friction resistance between the limit blocks 32, so the guide beads 37 play a guiding role in the sliding of the rectangular sliders 34, and the guide columns 39 are used to press the stacked guide beads 37 downward to prevent the guide beads 37 from moving up and down when the rectangular sliders 34 are displaced, causing a jam.

The starting end of the blanking slide 49 is at the same height as the corresponding three-jaw chuck 13. A blanking slide 49 is arranged below the docking assembly. The No. 2 workbench 51 is in a horizontal state and perpendicular to the No. 1 workbench 3, and a vertical support column 52 is fixedly provided on the top of the No. 2 workbench 51, and a horizontal welding table 53 is fixedly provided on the top of the support column 52, and the No. 2 clamping mechanism 56 is fixedly provided on the welding table 53, and the height of the No. 2 clamping mechanism 56 is consistent with the height of the corresponding three-jaw chuck 13, and the No. 2 clamping mechanism 56, the blanking slide 49, the drop plate 28 and the detector 1 are distributed in a matrix around one of the No. 1 clamping mechanisms.

[0059] The blanking slide 49 is used for the transmission shaft to slide from a high place into the collection box 50. Since the No. 2 clamping mechanism 56, the blanking slide 49, the drop plate 28 and the detector 1 are distributed in a matrix around one of the No. 1 clamping mechanisms, each time the rotating mechanism rotates 90°, the No. 1 clamping mechanism will face one of the above-mentioned devices. When the three-jaw chuck 13 faces the blanking slide 49, it is horizontally displaced to one side of the blanking slide 49 through the XY-axis slide 4, and the transmission shaft that has passed the inspection is placed on the blanking slide 49, and finally slides into the collection box 50 for collection through the action of the blanking slide 49, wherein the bottom of the collection box 50 can be paved A layer of sponge cushions the transmission shaft that slides downward to prevent the transmission shaft from being hit and having gaps or cracks. The No. 2 clamping mechanism 56 has the same structure as the No. 1 clamping mechanism and is used to clamp and rotate the transmission shaft. When the transmission shaft is located between the No. 1 clamping mechanism and the No. 2 clamping mechanism 56, the operator can process the unqualified transmission shaft by manual welding. After welding, the transmission shaft can be tested again by a dynamic balancing tester until it passes the test. The docking assembly enables the welding of the balance sheet to be achieved during the process of dynamic balancing the transmission shaft, which reduces the transportation time of a process and improves production efficiency.

[0060] A material storage cabinet 54 is fixedly arranged on the top of the second workbench 51 .

[0061] Since manual welding is adopted, a material storage cabinet 54 is arranged on the second workbench 51 for placing electric welding guns and balancing sheets, which is convenient for operators to take.

[0062] Two horizontal laser sensors 55 are fixedly disposed on the moving ends of the two XY-axis slides 4 , respectively. The laser emitting ends of the two laser sensors 55 are disposed facing each other, and the heights of the two laser sensors 55 are consistent.

[0063] First, when the laser beams of the two laser sensors 55 are on the same horizontal line, the two three-jaw chucks 13 are on the same horizontal line, so that the positioning of the two three-jaw chucks 13 can be achieved by positioning the two laser sensors 55, so that the three-jaw chuck 13 that clamps the transmission shaft can be accurately docked with the other three-jaw chuck 13. When in use, first adjust the position of one of the laser sensors 55 to the detection port of the detector 1, and allow the laser emitting end of the laser sensor 55 to pass through the detection port, and then through the distance adjustment function of the XY-axis slide 4, the output light of the two laser sensors 55 is located on the same horizontal line, and finally the positioning effect is achieved. Among them, the two laser sensors 55 can be electrically connected to the sound prompter through the controller. When the two laser sensors 55 are on the same horizontal line, the sound prompter emits a prompt sound to prompt the operator that the positioning has been successful. The sound prompter and the controller are not drawn in the figure.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
