Description

Technical Field

[0001] The present invention relates to the technical field of component testing, and in particular to a component rotating multi-dimensional testing device. Background Art

[0002] The tapping test of automobile axle 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 determine whether their mechanical structure and assembly quality meet the design requirements.

[0003] When there is a crack in the shaft, performing a tap test will result in an increase in the elastic variation.

[0004] The location and elastic variables of the shaft tap test will vary depending on the test conditions and material properties. Generally speaking, different locations of the tap test may result in the following changes: 1. When the tap position is close to the surface of the material, the elastic variable is usually larger because the surface layer is more susceptible to the impact force. 2. When the tap position is close to the center of the material, the elastic variable may be smaller because the impact force on the center part is dispersed. 3. The elastic variable will also change when tapping in different directions of the material, which is related to the anisotropy of the material. When using an existing tap test device, first align the device with the position or plane to be tested, then start the device to tap, collect the data generated by the tapping through the built-in sensor, and finally analyze the data to evaluate the characteristics of the material. Due to the limitations of the measurement principle and equipment design, the device can only operate on a single position or a single plane.

[0005] The existing tapping test can only be performed on one point or one surface, which will make it impossible to fully evaluate the overall quality of the shaft, may miss other potential defects, and have low test efficiency. It is necessary to move the tapping position multiple times for multi-point testing. The test results may be affected by local material properties and cannot represent the overall performance. It is difficult to find tiny cracks or other hidden defects inside the shaft. At the same time, the results of the shaft tapping test need to be displayed continuously to fully evaluate the shaft quality, avoid missing defects, improve test efficiency, reduce the impact of local characteristics, and find hidden defects such as internal tiny cracks. Summary of the invention

[0006] The purpose of the present invention is to propose a rotating multi-dimensional testing device for components in order to solve the problem that the traditional existing tapping test has a small scope, which makes it impossible to comprehensively evaluate the overall quality of the shaft and the existing shaft tapping test results cannot be continuously displayed to comprehensively evaluate the shaft quality.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a rotating multi-dimensional testing device for parts. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1 - Figure 6 and Fig. 9 As shown, a component rotating multi-dimensional testing device provided by the present invention comprises a mounting frame 10, which is arranged in a rectangular shape and has a test cavity therein, and two rotating mounting rods 11 are respectively detachably mounted on both sides of the test cavity of the mounting frame 10, and rectangular protrusions are arranged at both ends of the component shaft, and grooves matching the rectangular protrusions are arranged at the mutually close ends of the two mounting rods 11, so that the component shaft is clamped between the two mounting rods 11, and a driving member 30 for driving the mounting rods 11 to rotate is assembled on one side of the mounting frame 10, and the component shaft generally refers to the shaft responsible for transmission in the automobile, such as the automobile transmission shaft, etc., and these shafts will rotate during operation; The mounting frame 10 is provided with a plurality of knocking assemblies 40, which are arranged in an axial circular array around the mounting rod 11, and the mounting frame 10 is equipped with a planetary assembly 50 which is transmission-connected to the plurality of knocking assemblies 40 and the driving member 30, and the mounting frame 10 is provided with a telescopic assembly 60 which drives the plurality of knocking assemblies 40 to move horizontally, and the telescopic assembly 60 is transmission-connected to the driving member 30, and a display assembly 70 is installed in the test cavity of the mounting frame 10, and the display assembly 70 is transmission-connected to the knocking assembly 40 through a transmission assembly 80; Specifically, the planetary assembly 50 includes a sun gear 51 assembled on the outside of the mounting rod 11, a plurality of planetary gears 52 meshing with the sun gear 51, and an inner gear ring 53 fixedly mounted on the mounting frame 10 and meshing with the plurality of planetary gears 52. One end of the planetary gear 52 close to the mounting frame 10 is rotatably connected with a movable seat 55, and the mounting frame 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 frame 10 to prevent the planetary gear 52 from moving in the horizontal direction. The axles of the plurality of planetary gears 52 are fixedly mounted with transmission shafts 54, and the plurality of transmission shafts 54 are respectively connected to the plurality of knocking assemblies 40 in a transmission manner. Specifically, each knocking assembly 40 includes a rotating block 41 that is transmission-connected to the planetary assembly 50 and a knocking block 42 that is movably connected to the rotating block 41. The plurality of rotating blocks 41 are arranged in an axial annular array along the axis of the part. A sleeve 43 is fixedly mounted on each rotating block 41. The sleeve 43 is sleeved outside the transmission shaft 54. A card slot is provided inside the sleeve 43 along its length direction. A card block that matches the card slot is provided 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 slot is provided inside the knocking block 42, and a movable rod 44 that matches the through slot is provided on the knocking block 42. The knocking assembly 40 also includes a buffer spring 45 fixedly connected between the through slot and the movable rod 44. A circular movable frame 46 is installed on the side of the rotating block 41 away from the sleeve 43. A plurality of connecting pins 47 are fixedly connected to one side of the circular movable frame 46. The plurality of connecting pins 47 are respectively rotatably connected to the rotating axes of the plurality of rotating blocks 41. The driving member 30 includes a dual-axis motor 31 fixedly installed on the mounting frame 10. One end of the output shaft of the dual-axis motor 31 is fixedly connected to the mounting rod 11. 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 slot and compress the buffer spring 45. This action allows 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 slot, preparing for the next knocking of the knocking block 42.

[0017] The two ends of the part shaft are embedded between the two mounting rods 11. The mounting rod 11 is driven by one end of the dual-axis motor 31, thereby causing the part shaft to rotate. The rotation of the mounting rod 11 drives the rotation of the sun gear 51, and the inner gear ring 53 is firmly fixed on the mounting frame 10. As a result, the multiple planetary gears 52 rotate themselves while revolving around the sun gear 51. The transmission shaft 54 ​​keeps synchronization with the motion state of the planetary gears 52. The transmission shaft 54 ​​drives the sleeve 43 and the rotating block 41 to revolve around the sun gear 51 and rotate. The knocking block 42 on the rotating block 41 continuously performs rotational knocking on the part shaft to simulate the multi-dimensional vibration encountered by the part shaft during rotation. Finally, the elastic variable results of the part shaft are displayed through the display component 70.

[0018] like Figure 1 - Figure 2 and Figure 6 - Fig. 9As shown, the telescopic assembly 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, a U-shaped groove is provided on the top of the push frame 62 to match the bottom of the annular movable frame 46, a guide rod 63 parallel to the transmission screw 61 is provided on one side of the test cavity of the mounting frame 10, the guide rod 63 movably passes through the bottom of the push frame 62, one end of the transmission screw 61 is fixedly connected to a push gear 64, the other output shaft on the dual-axis motor 31 is fixedly connected to a one-way gear 65, and a transmission chain 66 is provided on the outer meshing sleeve of the one-way gear 65 and the push gear 64; The output shaft at the other end of the dual-axis motor 31 drives the one-way gear 65 to rotate, so that the one-way gear 65 is meshed with the transmission chain 66, thereby driving the push gear 64 to rotate, and then driving the transmission screw 61 to rotate, and the transmission screw 61 is threadedly engaged with the push rack 62, causing the push rack 62 to move horizontally along the guide rod 63, and at the same time, the U-shaped groove on the push rack 62 drives the annular moving rack 46, the rotating block 41, and the sleeve 43 to move along the length direction of the part axis, causing multiple knocking blocks 42 to knock along the length direction of the part axis, thereby forming multiple spiral knocking routes, improving the comprehensiveness of the knocking detection; when the dual-axis motor 31 reverses, the one-way gear 65 will not mesh with the transmission chain 66, causing the knocking blocks 42 on the multiple rotating blocks 41 to continuously rotate and knock on the corresponding length of the part axis, thereby only forming the knocking detection result of this length.

[0019] The display assembly 70 includes a fixed seat 71 fixedly installed in the test cavity and a vibration rod 72 sliding vertically thereon, the fixed seat 71 is located on the upper side of the part shaft, the vibration rod 72 penetrates the fixed seat 71, and an arc-shaped bonding plate 73 is provided at the bottom of the vibration rod 72, the arc-shaped bonding plate 73 is in contact with the upper surface of the part shaft, and a compression spring 74 is sleeved at the bottom of the vibration rod 72, and the compression spring 74 is located between the arc-shaped bonding plate 73 and the fixed seat 71. Since the middle position is usually the area of ​​the shaft that is most susceptible to impact and elastic variables, by measuring the elastic variables in this area, the overall strength and durability of the shaft can be more accurately evaluated. In addition, the elastic variable data at the middle position can better represent the overall reaction of the shaft under the action of external force, thereby providing a more reliable basis for the design and improvement of the shaft. Therefore, the fixed seat 71 and the arc-shaped bonding plate 73 of the present device are located at the middle position of the part shaft; A scoring needle 75 is horizontally fixed on the top of the vibration rod 72, and a scoring plate 76 matching the scoring needle 75 is movably installed in the test cavity of the mounting frame 10, and the scoring plate 76 is vertically arranged; the vibration of the part shaft will drive the arc-shaped bonding plate 73 to vibrate up and down, thereby driving the vibration rod 72 and the scoring needle 75 thereon to vibrate up and down on the scoring plate 76, and displaying the vibration amplitude of the part shaft. The high and low vibration amplitudes represent the intensity of the vibration when the part shaft is struck. The larger the vibration amplitude, the larger the elastic variable of the part shaft, and then the elastic variable of the part shaft is displayed. When there is a gap inside the part shaft or it is not assembled correctly, its vibration amplitude will increase accordingly, which is helpful to detect the comprehensive quality of the part shaft material and the assembly quality; 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.

[0020] 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. 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; 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.

[0021] Working principle, the two ends of the part shaft are fixed between the two mounting rods 11, and one end of the dual-axis motor 31 drives the mounting rod 11 to rotate, thereby causing the part shaft to rotate accordingly. The rotation of the mounting rod 11 in turn drives the sun gear 51 to rotate, thereby driving the multiple planetary gears 52 to both revolve around the sun gear 51 and rotate on their own. Multiple transmission shafts 54 match the motion state of the planetary gears 52, and 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. Therefore, the knocking block 42 on the rotating block 41 continuously rotates and knocks the part shaft, simulating the multi-dimensional vibration encountered by the part shaft during rotation. The vibration of the part shaft causes the arc-shaped bonding plate 73 to vibrate up and down, thereby causing the vibration rod 72 and the engraving needle 75 thereon to vibrate up and down accordingly on the engraving plate 76 to display the vibration amplitude of the part shaft, thereby reflecting the elastic variable of the part shaft; The output shaft of the dual-axis motor 31 is connected to the one-way gear 65 to rotate. The one-way gear 65 is meshed with the transmission chain 66, thereby driving the push gear 64 to rotate. The rotation of the push gear 64 drives the transmission screw 61 to rotate, and the transmission screw 61 is meshed 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 mobile frame 46, the rotating block 41, and the sleeve 43 to move along the axial direction of the part, so that multiple knocking blocks 42 knock along the axial direction, forming multiple spiral knocking paths, thereby enhancing the comprehensiveness of the knocking detection. During the horizontal movement process, the annular mobile frame 46 will push the transmission rack 82 to move along the slide tube 83, and the transmission rack 82 is meshed with the transmission gear 81, and 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 engraved plate 76 horizontally and form a continuous amplitude curve on the plate, which is convenient for displaying the results of the entire knocking test.

[0022] When the dual-axis motor 31 reverses, the one-way gear 65 will not mesh with the transmission chain 66, causing the knocking blocks 42 on the multiple rotating blocks 41 to continuously rotate and knock on the corresponding length of the part shaft, thereby only forming a knocking detection result of this length.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to a component rotating multi-dimensional testing device and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
