Description

Technical Field

[0001] This invention relates to the field of flywheel balance testing technology, and in particular to a dynamic balancing testing machine for flywheel production. Background Technology

[0002] A vertical balancing machine is a balancing machine with its drive spindle mounted vertically. Its measurement principle is basically the same as that of a general horizontal balancing machine. It is also available in soft support and hard support, and single-sided and double-sided types. However, it is suitable for parts without a spindle. Its drive spindle is mounted vertically and is suitable for testing various parts without a spindle, such as flywheels, grinding wheels, pulleys, clutches, turbine discs, tires, fans, etc.

[0003] Existing non-automatic vertical balancing machines require fixing the clamps before installing the flywheel. After placing the flywheel on the clamps, the flywheel needs to be fixed by tightening the bolts on the top of the clamps. Furthermore, when drilling holes in the flywheel is required for balancing tests, the flywheel needs to be installed and removed repeatedly. Therefore, this application provides a dynamic balancing testing machine for flywheel production to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dynamic balancing testing machine for flywheel production to solve the problem that existing non-automatic vertical balancing machines require fixing the clamp first when installing the flywheel, and after placing the flywheel on the clamp, the flywheel still needs to be fixed by tightening the bolts on the top of the clamp.

[0012] Optionally, the extrusion unit includes a third rotating shaft rotatably connected to the top of the extrusion section. Two extrusion rods with a 60° included angle are fixedly connected to the outer wall of the third rotating shaft. A connecting block is fixedly connected to the top of the extrusion rods. An embedding groove is provided on one side of the connecting block. A fourth rotating shaft is fixedly connected to the inner wall of the embedding groove. The extrusion plate is rotatably connected to the connecting block through the fourth rotating shaft. A protective pad is fixedly connected to one side of the extrusion plate.

[0013] Optionally, the snap-fit ​​structure includes a cover plate located at the top of the central tube, and an annular cylinder is fixedly connected to the bottom of the cover plate.

[0014] Optionally, the first connecting unit includes four slide bars that are fixedly connected to the bottom of the cover plate and are evenly distributed.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting up a support and compression structure, the flywheel and the manual pressure of the operator are used as the power source. The support and compression structure converts the force into a horizontal clamping force, thereby achieving compression and fixation of the inner wall of the flywheel. This is in line with the principles of mechanics and can greatly accelerate the fixing and disassembly time of the flywheel for non-automatic balancing machines.

[0018] Four supporting extrusion structures are evenly distributed on the central tube. When the flywheel is extruded to the preset position, the distance of the extrusion plate is consistent. When the flywheel is placed, it can be automatically centered to ensure that the axis of the flywheel coincides with the axis of the central tube.

[0019] By setting a snap-fit ​​structure to limit the support and compression structure, the support and compression structure is locked in place, preventing it from shaking during rotation and causing inaccurate test results. Attached Figure Description

Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0033] The dynamic balancing testing machine for flywheel production provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0034] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0035] Generally, terms can be understood at least partly from their use in context.

[0038] like Figures 1 to 9 As shown, an embodiment of the present invention provides a dynamic balancing testing machine for flywheel production, including a balancing machine body 1. A data display 2 and a drilling machine 3 are fixedly connected to the top two sides of the balancing machine body 1, respectively. The balancing machine body 1, data display 2, and drilling machine 3 are existing technologies. A drive device is provided inside the balancing machine body 1. A turntable 4 is fixedly connected to the output end of the drive device. A clamping base 5 is fixedly connected to the top of the turntable 4. During operation, the drive device inside the balancing machine body 1 drives the turntable 4 to rotate. A transfer structure 6 is located on top of the clamping base 5 and is connected to the clamping base 5. Structure 6 is aligned with the output shaft of the drive unit; a support and compression structure 7 is located at the bottom of the transfer structure 6, and the transfer structure 6 is connected to the support and compression structure 7, which is used to position and clamp the flywheel; a snap-fit ​​structure 8 is located on the transfer structure 6, and the transfer structure 6 is connected to the snap-fit ​​structure 8, which is used to limit the support and compression structure 7; it also includes a first connecting unit connecting the transfer structure 6 and the snap-fit ​​structure 8, a second connecting unit connecting the transfer structure 6 and the support and compression structure 7, and a third connecting unit connecting the snap-fit ​​structure 8 and the support and compression structure 7.

[0039] When a flywheel needs to be balanced, it is placed on the support and compression structure 7. The support and compression structure 7 uses the weight of the flywheel and the pressure applied by the operator to compress and fix the inner wall of the flywheel. After the flywheel is fixed by the support and compression structure 7, the locking structure 8 limits the support and compression structure 7, thereby locking the support and compression structure 7 to prevent it from shaking during rotation, which could lead to inaccurate test results.

[0040] like Figures 1 to 5 As shown, a scale 41 is fixedly connected to the bottom of the turntable 4. The scale 41 is used to provide the drilling angle during subsequent drilling adjustments. The fixture base 5 and the turntable 4 are respectively provided with corresponding fixing holes. The fixture base 5 and the turntable 4 are fixed together by bolts 51. The outer wall of the fixture base 5 is provided with a number of evenly spaced counterweight holes 52. There are 360 ​​counterweight holes 52, corresponding to 360°. A counterweight column 53 is fixedly connected to the counterweight hole 52. The counterweight column 53 is a threaded rod with one end adapted to the counterweight hole 52 and the other end is provided with a hole adapted to the threaded rod, so that multiple counterweight columns 53 can be fixedly connected. Each counterweight column 53 weighs 1g. When the counterweight is balanced by the counterweight column 53, the counterweight will not fall off due to the high-speed rotation of the turntable 4.

[0041] like Figure 2 , Figure 3 and Figure 5 As shown, the transfer structure 6 includes a central shaft tube 61 fixedly connected to the top of the fixture base 5. Four sector blocks 63 are fixedly connected to the bottom of the central shaft tube 61. The central shaft tube 61 is fixed to the fixture base 5 by the four sector blocks 63 and the central shaft tube 61, which makes the central shaft tube 61 more stable during rotation. At the same time, the sector blocks 63 can restrict the rotation path of the supporting extrusion structure 7, increasing the accuracy of the supporting extrusion structure 7 during operation. When the central shaft tube 61 rotates, the sector blocks 63 can assist in positioning the supporting extrusion structure 7 with the snap-fit ​​structure 8 to avoid shaking. Every two adjacent sector blocks 63 are distributed at 90°. The four sector blocks 63 are spaced apart by a cross-shaped rotation groove 65. The outer wall of the central shaft tube 61 has four evenly distributed clamping grooves 62. All four clamping grooves 62 are connected to the rotation grooves 65. The rotation grooves 65 and the clamping grooves 62 cooperate to provide the installation position and path for the supporting extrusion structure 7.

[0042] like Figures 3 to 7As shown, the supporting extrusion structure 7 includes a first rotating rod 71 rotatably connected to the inner wall of the clamping groove 62. The first rotating rod 71 is formed by a pressing section 711, a rotating section 712, and a load-bearing section 713 fixedly connected in sequence. The rotating section 712 and the load-bearing section 713 form a 160° angle, and the rotating section 712 and the pressing section 711 form a 35° angle. The length of the load-bearing section 713 is greater than the lengths of the pressing section 711 and the rotating section 712. The second connecting unit includes a second rotating shaft 715 fixedly connected to one end of the rotating section 712. A rotating hole adapted to the second rotating shaft 715 is opened at a corresponding position on the inner wall of the clamping groove 62. A limiting strip parallel to the load-bearing section 713 is connected to the outer wall of the second rotating shaft 715. The limiting strip is located on the inner wall of the rotating hole. A limiting strip groove adapted to the limiting strip is provided at a relative position. A stop block is fixed on the inner wall of the limiting strip groove at a position parallel to the fixture base 5. Therefore, when the first rotating rod 71 rotates to a position parallel to the fixture base 5, the limiting strip stops moving under the limitation of the stop block. Therefore, when the load-bearing section 713 rotates to a position parallel to the fixture base 5, it is the preset position for the flywheel to press down. The end of the extrusion section 711 near the rotating section 712 is fixedly connected to the first rotating shaft 714. The first rotating rod 71, the second rotating shaft 715, and the first rotating shaft 714 are made of high-quality alloy steel and have undergone quenching heat treatment to improve wear resistance and strength. The side wall of the fan-shaped block 63 is provided with a guide groove 64 adapted to the path of the first rotating shaft 714. The diameter of the first rotating shaft 714 and the guide groove 64 are... The width of section 4 is consistent, and no lateral displacement occurs when the first rotating shaft 714 slides inside the guide groove 64. A support plate 72 is fixedly connected to the bottom end of the first rotating rod 71, and an installation sleeve 721 is fixedly connected to the bottom of the support plate 72. The installation sleeve 721 is fitted and fixed to one end of the load-bearing section 713. The support plate 72 is installed at one end of the load-bearing section 713 through the installation sleeve 721, so that the support plate 72 can be detached. When the support plate 72 does not meet the standard, it can be replaced at any time. An extrusion unit 73 is rotatably connected to the top end of the first rotating rod 71, and an extrusion plate 77 is rotatably connected to one end of the extrusion unit 73. The extrusion unit 73 includes a third rotating shaft 731 rotatably connected to the top end of the extrusion section 711. The outer wall of the third rotating shaft 731 is fixedly connected to There are two extrusion rods 732 at a 60° angle, and a connecting block 74 is fixedly connected to the top of the extrusion rods 732. An embedding groove 741 is opened on one side of the connecting block 74, and a fourth rotating shaft 742 is fixedly connected to the inner wall of the embedding groove 741. The extrusion plate 77 is rotatably connected to the connecting block 74 through the fourth rotating shaft 742. A protective pad 771 is fixedly connected to one side of the extrusion plate 77. The protective pad 771 can protect the inner wall of the flywheel and prevent the extrusion plate 77 from contacting and squeezing the inner wall of the flywheel, which would cause slight deformation. By adjusting the angle between the two extrusion rods 732, the travel distance of the extrusion plate 77 can be adjusted. When the user needs to test the balance of flywheels with other inner diameters, the extrusion unit 73 can be replaced to fix flywheels with different inner diameters.

[0043] When the flywheel presses down on the four support plates 72, the support plates 72 transmit the pressure to the load-bearing section 713. As the load-bearing section 713 moves downwards under pressure, it rotates within the rotating hole via the second rotating shaft 715. The rotating load-bearing section 713 drives the rotating section 712 and the extrusion section 711 to move in opposite directions. Since the rotating section 712 and the extrusion section 711 form a 35° angle, the extrusion section 711 drives the extrusion plate 77 connected to the extrusion unit 73 to move towards the inner wall of the flywheel until... When the flywheel is pressed down to the preset position, the four extrusion plates 77 press and fix the inner wall of the flywheel, thereby limiting and fixing the flywheel. The flywheel is pressed onto the support plate 72 by its own weight and the worker's pressing, and is locked and limited by the four extrusion plates 77. Since the four first rotating rods 71 ​​are evenly distributed, when the flywheel is pressed to the preset position, the travel distance of the extrusion plates 77 is consistent. When the flywheel is placed, it can automatically center the flywheel, ensuring that the center of the flywheel is located on the axis of the central tube 61.

[0044] like Figure 4 , Figure 5 and Figures 7 to 9 As shown, the snap-fit ​​structure 8 includes a cover plate 81 located at the top of the central tube 61. The cover plate 81 allows workers to easily insert and remove the snap-fit ​​structure 8. An annular cylinder 82 is fixedly connected to the bottom of the cover plate 81. The first connecting unit includes four sliding strips 83 that are evenly distributed at the bottom of the cover plate 81. The inner wall of the central tube 61 has four evenly distributed sliding grooves 66. Each sliding groove 66 is distributed at a 45° angle with the adjacent clamping groove 62. The sliding grooves 66 are adapted to the sliding strips 83. When the snap-fit ​​structure 8 is installed on the central tube 61, the four sliding strips 83 below the cover plate 81 are inserted into the corresponding sliding grooves 66 on the central tube 61.

[0045] The third connecting unit includes two extrusion columns 75 located on one side of the extrusion plate 77. The length of the extrusion column 75 fixed below the extrusion plate 77 is greater than the length of the extrusion column 75 fixed above the extrusion plate 77. A hemisphere 76 is fixedly connected to the top of each of the two extrusion columns 75. A first eccentric ball 85 is connected to the outer wall of the annular cylinder 82 relative to the upper hemisphere 76. A first baffle 84 is fixedly connected to the top outer wall of the annular cylinder 82 near the first eccentric ball 85. Four abutment rods 86 are fixedly connected to the bottom of the cover plate 81 relative to the lower extrusion column 75. A second eccentric ball 88 is connected to the outer side of the abutment rod 86 corresponding to the hemisphere 76. A second baffle 87 is fixedly connected to the outer wall of the abutment rod 86 near the top of the second eccentric ball 88. The first baffle 84 and the second baffle 87 have the same structure and dimensions, as do the first eccentric ball 85 and the second eccentric ball 88. The first eccentric ball 85 can be limited by the first baffle 84 and the hemisphere 76. The interior of the hemisphere 76 is a hollow spherical structure, and the diameter of the spherical structure is the same as the diameter of the first eccentric ball 85. The hemisphere 76 has an opening of 1 / 3 of the sphere facing the first eccentric ball 85, so that the first eccentric ball 85 can smoothly enter the interior of the hemisphere 76. At the same time, the hemisphere 76 provides support for the bottom and sides of the first eccentric ball 85. The bottom of the annular cylinder 82 is fixedly connected with a convex ring. The top of the extrusion section 711 has a first limiting groove 7111 that is perpendicular to the surface of the clamp base 5. The outer wall of the third rotating shaft 731 has a second limiting groove 7311 that matches the first limiting groove 7111. When the extrusion plate 77 is in a vertical state, the second limiting groove 7311 is connected to the first limiting groove 7111. The convex ring matches the first limiting groove 7111 and the second limiting groove 7311.

[0046] After the supporting compression structure 7 limits and fixes the flywheel, the second limiting groove 7311 is connected to the first limiting groove 7111. Both the second limiting groove 7311 and the first limiting groove 7111 are facing each other relative to the annular cylinder 82. The four sliding strips 83 on the cover plate 81 are inserted into the sliding groove 66. During the insertion of the sliding strips 83, the convex ring fixed at the bottom of the annular cylinder 82 is engaged in the second limiting groove 7311 and the first limiting groove 7111. At the same time, the first eccentric ball 85 located on the surface of the annular cylinder 82 is engaged in the upper part of the convex ring. Inside the hemisphere 76, the second eccentric ball 88 located on the surface of the push rod 86 is inserted into the lower hemisphere 76. The first eccentric ball 85 and the second eccentric ball 88 provide pressure on the extrusion column 75. When the annular cylinder 82 rotates with the central shaft tube 61, the first eccentric ball 85 and the second eccentric ball 88 will generate a biasing force to the outside during the rotation, thereby extruding the extrusion column 75 through the biasing force. This increases the extrusion pressure of the extrusion plate 77 on the inner wall of the flywheel during the balance test, making the flywheel more stable during the test.

[0047] The working principle of the technical solution provided by this invention is as follows: When the flywheel needs to be balanced, the flywheel is placed on the support and extrusion structure 7. When the flywheel is pressed on the four support plates 72, the support plates 72 will transmit the pressure to the load-bearing section 713. When the load-bearing section 713 is subjected to pressure and moves downward, it rotates in the rotating hole through the second rotating shaft 715. The rotating load-bearing section 713 drives the rotating section 712 and the extrusion section 711 to move in opposite directions. Since the rotating section 712 and the extrusion section 711 are at a 35° angle, the extrusion section 711 will drive the extrusion plate 77 connected to the extrusion unit 73 to move towards the inner wall of the flywheel until the flywheel is pressed down to the preset position. The four extrusion plates 77 just squeeze and fix the inner wall of the flywheel, thereby limiting and fixing the flywheel. The flywheel is pressed onto the support plate 72 by its own weight and the pressure of the staff, and is locked and limited by the four extrusion plates 77.

[0048] After the supporting compression structure 7 limits and fixes the flywheel, the second limiting groove 7311 is connected to the first limiting groove 7111. Both the second limiting groove 7311 and the first limiting groove 7111 are facing each other relative to the annular cylinder 82. The four sliding strips 83 on the cover plate 81 are inserted into the sliding groove 66. During the insertion of the sliding strips 83, the convex ring fixed at the bottom of the annular cylinder 82 is engaged in the second limiting groove 7311 and the first limiting groove 7111. At the same time, the first eccentric ball 85 located on the surface of the annular cylinder 82 is engaged in the upper part of the convex ring. Inside the hemisphere 76, the second eccentric ball 88 located on the surface of the push rod 86 is inserted into the lower hemisphere 76. The first eccentric ball 85 and the second eccentric ball 88 provide pressure on the extrusion column 75. When the annular cylinder 82 rotates with the central shaft tube 61, the first eccentric ball 85 and the second eccentric ball 88 will generate a biasing force to the outside during the rotation, thereby extruding the extrusion column 75 through the biasing force. This increases the extrusion pressure of the extrusion plate 77 on the inner wall of the flywheel during the balance test, making the flywheel more stable during the test.
