Description

Technical Field

[0001] The present invention relates to the technical field of component testing, and particularly to a rotary multi-dimensional testing device for components. Background Art

[0002] The percussion test of automotive shaft parts is used to detect whether there are defects such as cracks and inclusions inside the parts, evaluate their structural integrity and fatigue life; and judge whether their mechanical structure and assembly quality meet the design requirements.

[0003] When there is a crack on the shaft, performing a percussion test will cause an increase in elastic variables.

[0004] The position of the shaft percussion test and the elastic variable will vary due to test conditions and material properties. Generally speaking, different percussion test positions may lead to the following changes: 1. When the percussion position is close to the material surface, the elastic variable is usually larger because the surface layer is more easily affected by the impact force. 2. When the percussion position is close to the material center, the elastic variable may be smaller because the impact force received by the central part is dispersed. 3. Percussing in different directions of the material will also cause changes in the elastic variable, which is related to the anisotropy of the material. When using the existing percussion test device, first align the device with the position or plane to be tested, then start the device to perform percussion, collect the data generated by the percussion through the built-in sensor, and finally analyze these data to evaluate the properties of the material. Due to the limitations of the measurement principle and device design, the device can only operate on a single position or a single plane.

[0005] The existing percussion test can only be carried out on a single point or a single surface, which will result in the inability to comprehensively evaluate the overall quality of the shaft, may miss other potential defects, has low test efficiency, requires multiple moves of the percussion position for multi-point testing, the test results may be affected by local material properties and cannot represent the overall performance, and it is difficult to detect tiny cracks or other hidden defects inside the shaft; at the same time, the results of the shaft percussion test need to be continuously displayed to comprehensively evaluate the shaft quality, avoid missing defects, improve the test efficiency, reduce the influence of local properties, and detect hidden defects such as tiny cracks inside. Summary of the Invention

[0021] 2. When the biaxial motor rotates in reverse, the one-way gear will not engage with the transmission chain.

The two states can be switched at any time, thus facilitating the knocking detection of the part shaft. Description of the Drawings

[0039] Next, the accompanying drawings in the embodiments of the present invention will be used to clearly and completely describe the technical solution of a multi-dimensional test device for rotating parts in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] As Figure 1 - Figure 6 And Figure 9 shown, a multi-dimensional test device for rotating parts provided by the present invention includes a mounting frame 10. The mounting frame 10 is rectangularly arranged, and a test cavity is provided inside the mounting frame 10. Two rotating mounting rods 11 are respectively detachably installed on both sides of the test cavity of the mounting frame 10. The two ends of the part shaft have rectangular protrusions, and grooves adapted to the rectangular protrusions are provided at the mutually approaching ends of the two mounting rods 11, so that the part shaft is clamped between the two mounting rods 11. A driving member 30 for driving the mounting rod 11 to rotate is assembled on one side of the mounting frame 10. The part shaft usually refers to the shaft responsible for transmission in an automobile, such as an automobile transmission shaft, etc. These shafts will rotate during operation;

[0041] The mounting bracket 10 is provided with a plurality of knocking components 40. The plurality of knocking components 40 are arranged in a circular array around the axis of the mounting rod 11. And a planetary component 50 is assembled on the mounting bracket 10 and is in transmission connection with the plurality of knocking components 40 and the driving member 30. The mounting bracket 10 is provided with a telescopic component 60 for driving the plurality of knocking components 40 to move horizontally, and the telescopic component 60 is in transmission connection with the driving member 30. A display component 70 is assembled in the test cavity of the mounting bracket 10, and the display component 70 is in transmission connection with the knocking component 40 through a transmission component 80;

[0042] Specifically, the planetary component 50 includes a sun gear 51 assembled outside the mounting rod 11, a plurality of planetary gears 52 meshing with the sun gear 51, and an internal gear ring 53 fixedly installed on the mounting bracket 10 and meshing with the plurality of planetary gears 52. A movable seat 55 is rotatably connected to one end of the planetary gear 52 close to the mounting bracket 10. And the mounting bracket 10 is provided with an annular groove 56 adapted to the movable seat 55. The annular groove 56 clamps the movable seat 55 on the mounting bracket 10 to prevent the planetary gear 52 from moving horizontally. A transmission shaft 54 is fixedly installed at the axis of each of the plurality of planetary gears 52, and the plurality of transmission shafts 54 are respectively in transmission connection with the plurality of knocking components 40;

[0043] Specifically, each knocking component 40 includes a rotating block 41 in transmission connection with the planetary component 50 and a knocking block 42 movably connected to the rotating block 41. The plurality of rotating blocks 41 are arranged in a circular array along the axis of the part shaft. A sleeve 43 is fixedly installed on each rotating block 41. The sleeve 43 is sleeved outside the transmission shaft 54. A card slot is opened in the inner part of the sleeve 43 along its length direction, and a card block adapted to the card slot is arranged outside the transmission shaft 54, so that the transmission shaft 54 can drive the card slot and the sleeve 43 to rotate through the card block. A through groove is opened in the knocking block 42, and a movable rod 44 adapted to the through groove is arranged on the knocking block 42;

[0044] The knocking component 40 further includes a buffer spring 45 fixedly connected between the through groove and the movable rod 44. An annular moving frame 46 is installed on one side of the rotating block 41 away from the sleeve 43. One side of the annular moving frame 46 is fixedly connected with a plurality of connecting pins 47, and the plurality of connecting pins 47 are respectively rotatably connected to the rotation axes of the plurality of rotating blocks 41. The driving member 30 includes a double-shaft motor 31 fixedly installed on the mounting bracket 10, and one output shaft of the double-shaft motor 31 is fixedly connected with the mounting rod 11;

[0045] During the knocking process, the knocking block 42 collides with the part shaft. As the knocking block 42 moves, it and the movable rod 44 slide inward along the through groove and compress the buffer spring 45. This action enables the rotating block 41 and the knocking block 42 to smoothly rotate around the part shaft. Subsequently, the compressed buffer spring 45 releases energy, pushing the knocking block 42 and the movable rod 44 to slide outward along the through groove to prepare for the next knock of the knocking block 42.

[0046] Both ends of the part shaft are embedded between two mounting rods 11. One end of the dual-axis motor 31 is used to drive the mounting rods 11, thereby causing the part shaft to rotate. The rotation of the mounting rods 11 drives the rotation of the sun gear 51, while the internal gear ring 53 is firmly fixed to the mounting frame 10. Thus, while multiple planetary gears 52 revolve around the sun gear 51, they also perform their own rotation. The transmission shaft 54 is synchronized with the motion state of the planetary gears 52. The transmission shaft 54 drives the sleeve 43 and the rotating block 41 to revolve and rotate around the sun gear 51. The knocking block 42 on the rotating block 41 continuously performs rotational knocking on the part shaft to simulate the multi-dimensional vibrations encountered by the part shaft during rotation. Finally, the elastic variable results of the part shaft are displayed through the display component 70.

[0047] As Figure 1 - Figure 2 and Figure 6 - Figure 9 As shown in the figure, the telescopic component 60 includes a transmission screw 61 rotatably mounted at the bottom of the mounting frame 10. A push frame 62 is threadedly connected to the transmission screw 61. The top of the push frame 62 is provided with a U-shaped groove adapted to the bottom of the annular moving frame 46. One side of the test cavity of the mounting frame 10 is provided with a guide rod 63 parallel to the transmission screw 61. The guide rod 63 movably penetrates through the bottom of the push frame 62. One end of the transmission screw 61 is fixedly connected to a push gear 64. Another output shaft of the dual-axis motor 31 is fixedly connected to a one-way gear 65. A transmission chain 66 is sleeved outside the one-way gear 65 and the push gear 64 in an externally meshing manner;

[0048] The output shaft at the other end of the biaxial motor 31 drives the one-way gear 65 to rotate, causing the one-way gear 65 to mesh with the transmission chain 66, thereby driving the push gear 64 to rotate, and further driving the transmission screw 61 to rotate. The transmission screw 61 is in threaded engagement with the push frame 62, causing the push frame 62 to move horizontally along the guide rod 63. At the same time, the U-shaped groove on the push frame 62 drives the annular moving frame 46, the rotating block 41, and the sleeve 43 to move along the length direction of the part shaft, causing the plurality of knocking blocks 42 to knock along the length direction of the part shaft, thereby forming a plurality of spiral knocking routes and improving the comprehensiveness of the knocking detection. When the biaxial motor 31 rotates in reverse, the one-way gear 65 will not mesh with the transmission chain 66, causing the knocking blocks 42 on the plurality of rotating blocks 41 to continuously rotate and knock on the corresponding length of the part shaft, thereby only forming the knocking detection result of this length.

[0049] The display assembly 70 includes a fixed seat 71 fixedly installed in the test cavity and a vibrating rod 72 sliding vertically thereon. The fixed seat 71 is located on one side above the part shaft. The vibrating rod 72 penetrates the fixed seat 71, and an arc-shaped fitting plate 73 is provided at the bottom of the vibrating rod 72. The arc-shaped fitting plate 73 is in contact with the upper surface of the part shaft. A compression spring 74 is sleeved on the bottom of the vibrating rod 72, and the compression spring 74 is located between the arc-shaped fitting plate 73 and the fixed seat 71. Since the middle position is usually the area of the shaft that is most vulnerable to impact and elastic deformation, by measuring the elastic deformation in this area, the overall strength and durability of the shaft can be more accurately evaluated. In addition, the elastic deformation data of the middle position can better represent the overall response of the shaft under external force, thus providing a more reliable basis for the design and improvement of the shaft. Therefore, the fixed seat 71 and the arc-shaped fitting plate 73 of this device are located at the middle position of the part shaft;

[0050] A marking needle 75 is horizontally fixed at the top of the vibrating rod 72. A marking plate 76 matching the marking needle 75 is movably installed in the test cavity of the mounting frame 10, and the marking plate 76 is vertically arranged. The vibration of the part shaft will drive the arc-shaped fitting plate 73 to vibrate up and down, thereby driving the vibrating rod 72 and the marking needle 75 thereon to vibrate up and down on the marking plate 76, displaying the vibration amplitude of the part shaft. The height of the vibration amplitude represents the intensity of the vibration when the part shaft is knocked. The larger the vibration amplitude, the greater the elastic deformation of the part shaft, and thus the elastic deformation of the part shaft is displayed. When there are gaps or incorrect assembly inside the part shaft, its vibration amplitude will increase accordingly, which helps to detect the comprehensive quality of the part shaft material and the assembly quality;

[0051] The display assembly 70 further includes a transmission member 77 fixedly mounted on the mounting frame 10 and driving the depiction plate 76 to move horizontally, and the transmission member 77 is transmission-connected to the knocking assembly 40 via a transmission assembly 80. The transmission member 77 includes a plurality of transmission rollers 771 rotatably mounted in the test cavity, and the plurality of transmission rollers 771 are arranged opposite to each other on both sides of the depiction plate 76, and the transmission rollers 771 arranged opposite to each other are transmission-connected to each other via two meshing gears 772.

[0052] Specifically, the transmission assembly 80 includes a transmission gear 81 fixedly mounted on one end of one of the transmission rollers 771 and a transmission rack 82 horizontally slidably mounted inside the test chamber. The transmission rack 82 is meshed and transmission-connected with the transmission gear 81, and a slide tube 83 adapted to the transmission rack 82 is fixedly mounted on the mounting frame 10. A T-shaped slider 84 is provided at one end of the transmission rack 82 away from the slider 83. The annular movable frame 46 is provided with an annular groove adapted to the T-shaped slider 84 along its rotation axis. The cross section of the T-shaped slider 84 is T-shaped, so that one end of the transmission rack 82 can always be clamped in the annular groove on the annular movable frame 46.

[0053] When the annular moving frame 46 performs horizontal displacement, it moves the transmission rack 82 horizontally along the slide tube 83, thereby realizing the precise meshing transmission between the transmission rack 82 and the transmission gear 81, and the transmission roller 771 drives another transmission roller 771 to rotate in the opposite direction through two meshing gears 772, ensuring that the two transmission rollers 771 work synchronously and push the engraved plate 76 to move horizontally. This mechanism ensures that a continuous amplitude curve is formed on the engraved plate 76, so as to fully display the knocking test results;

[0054] At the same time, the horizontal movement of the engraved plate 76 matches the horizontal movement of the annular moving frame 46. When the annular moving frame 46 performs reverse horizontal movement, the amplitude curve on the engraved plate 76 also corresponds to the knocking position of the part axis, so that the entire part axis can be knocked for multiple length cycles, thereby more accurately displaying its knocking detection results.

[0055] Working principle: Both ends of the part shaft are fixed between two mounting rods 11. One end of the dual-shaft motor 31 drives the mounting rod 11 to rotate, and then the part shaft rotates accordingly. The rotation of the mounting rod 11 drives the sun gear 51 to rotate, and then drives multiple planetary gears 52 to revolve around the sun gear 51 and rotate on their own axes. The movement states of multiple transmission shafts 54 match those of the planetary gears 52. The transmission shafts 54 drive the sleeve 43 and the rotating block 41 to rotate around the sun gear 51 and rotate on their own axes. The knocking blocks 42 on the rotating block 41 thus continuously perform rotational knocking on the part shaft, simulating the multi-dimensional vibrations encountered by the part shaft during rotation. The vibration of the part shaft causes the arc-shaped fitting plate 73 to vibrate up and down, and then causes the vibrating rod 72 and the engraving needle 75 thereon to perform corresponding up and down vibrations on the engraving plate 76 to display the vibration amplitude of the part shaft, thereby reflecting the elastic variable of the part shaft;

[0056] The output shaft of the dual-shaft motor 31 is connected to the one-way gear 65 to make it rotate. The one-way gear 65 meshes with the transmission chain 66, and then drives the push gear 64 to rotate. The rotation of the push gear 64 drives the transmission screw 61 to rotate. The transmission screw 61 meshes with the thread of the push frame 62, causing the push frame 62 to move horizontally along the guide rod 63. The U-shaped groove on the push frame 62 guides the annular moving frame 46, the rotating block 41, and the sleeve 43 to move along the part axis, so that multiple knocking blocks 42 perform axial knocking, forming multiple spiral knocking paths, thereby enhancing the comprehensiveness of the knocking detection. During the horizontal movement of the annular moving frame 46, it will push the transmission rack 82 to move along the sliding tube 83. The transmission rack 82 meshes with the transmission gear 81. The transmission gear 81 drives another transmission roller 771 to rotate in the opposite direction through two meshing gears 772. In this way, the two transmission rollers 771 work together to move the engraving plate 76 horizontally and form a continuous amplitude curve on the plate, facilitating the display of the results of the entire knocking test.

[0057] When the dual-shaft motor 31 rotates in the reverse direction, the one-way gear 65 will not mesh with the transmission chain 66, resulting in the knocking blocks 42 on multiple rotating blocks 41 continuously performing rotational knocking on the corresponding length of the part shaft, so that only the knocking detection results of this length will be formed.

[0058] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
