Description

Technical Field

[0001] This invention relates to the field of automated vibration detection technology for parts, specifically to an automated vibration detection device for parts. Background Technology

[0002] Automated vibration testing of components is primarily based on the principles of vibration testing. It involves simulating vibration conditions in the actual working environment, exciting the components, and measuring their response. According to the physical properties of the components being tested, vibration testing methods can be mainly divided into three categories: electrical measurement methods, optical measurement methods, and mechanical measurement methods.

[0003] Currently, the mechanical measurement method for component vibration testing involves using a vibration test bench. The component is mounted on the test bench using screws, and a vibration sensor is installed near the component. However, since the components being tested are different each time, the existing method uses adhesive to fix the vibration sensor to the test bench. While this method facilitates the installation of the vibration sensor, it can easily damage the sensor when it is disassembled. Furthermore, after repeated application of adhesive to the bottom of the vibration sensor, a significant amount of adhesive residue remains, affecting the installation of the sensor and further impacting the component vibration detection.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] Please see Figure 1An automated vibration testing device for parts includes a vibration table 1, a table 2 mounted on the vibration table 1, and a control device 3 for controlling the vibration table 1. The vibration table 1 and the control device are components of existing vibration test benches, so they will not be described in detail. The table 2 has multiple mounting holes 21 arranged in a rectangle, and internal threaded sleeves 4 are installed inside the mounting holes 21. Two internal threaded sleeves 4 are threadedly connected to screws 5. A pressure plate 51 for fixing parts is provided between the two screws 5, and two fixing bolts 52 are provided on the pressure plate 51. The fixing bolts 52 are threadedly connected to the screws 5.

[0041] When performing vibration testing on a part, the part is placed in a box or directly on the table 2. The height of the pressure plate 51 relative to the two screws 5 is adjusted to further fix the part. Then, the part is fixed to the table 2 by rotating the fixing bolt 52.

[0042] Please see Figures 1 to 4 The screw 5 is also provided with a vibration sensor 6 for detecting the vibration amplitude near the part. The bottom of the vibration sensor 6 is fixedly installed with a fixing shell 61. The vibration sensor 6 can be fixed to the fixing shell 61 by glue or welding. In this embodiment, the fixing shell 61 is open at the top, which facilitates the linear connection of the vibration sensor 6.

[0043] Furthermore, a connecting and fixing mechanism 7 is installed at the bottom of the fixed housing 61, and the connecting and fixing mechanism 7 fixes the vibration sensor 6 at the mounting hole 21 near the screw 5;

[0044] Please see Figure 4 and Figures 6 to 8 The connecting and fixing mechanism 7 includes a connecting sleeve 71, a positioning element 72, a locking sleeve 73, and an inner support element 74. The connecting sleeve 71 passes through the mounting hole 21. The positioning element 72 is located inside the connecting sleeve 71. The bottom of the connecting sleeve 71 and the position corresponding to the positioning element 72 are provided with a positioning port 711. The positioning element 72 is used to make the bottom of the connecting sleeve 71 and the bottom of the table 2 lock together.

[0045] The connecting sleeve 71 has an external thread on its top outer side, and the locking sleeve 73 has an internal thread hole on its top. The locking sleeve 73 is threadedly connected to the connecting sleeve 71. In this embodiment, multiple rotating rods are arranged around the outside of the locking sleeve 73, which facilitates the operator to rotate the locking sleeve 73. The inner support 74 is arranged on the outside of the connecting sleeve 71, and the inner support 74 is staggered with the positioning port 711.

[0046] The positioning component 72 includes a fixing plate 721, a connecting rod 722, a connecting plate 723, a connecting spring 724, a pushing block 725, and a clamping component 726. The fixing plate 721 is fixedly installed at the top end inside the connecting sleeve 71. The connecting rod 722 slides through the fixing plate 721, and the connecting plate 723 is fixedly sleeved on the outside of the bottom of the connecting rod 722. The connecting spring 724 is sleeved on the outside of the connecting rod 722, and both ends of the connecting spring 724 are fixedly connected to the fixing plate 721 and the connecting plate 723, respectively.

[0047] The push block 725 is fixedly installed on the top of the connecting rod 722, and one end of the push block 725 extends to the outside of the connecting sleeve 71. The connecting sleeve 71 is provided with a moving port corresponding to the position of the push block 725.

[0048] The clamping element 726 is installed at the bottom of the connecting rod 722, and the clamping element is connected to the two positioning ports 711.

[0049] The clamping component 726 includes a connecting rod 7261, a clamping rod 7262, and a connecting shaft 7263. There are two connecting rods 7261, which are rotatably connected to the outer side of the bottom of the connecting rod 722 via hinge supports. The other end of the connecting rod 7261 is rotatably connected to the clamping rod 7262 via a hinge support. The connecting shaft 7263 is fixedly installed at one end of the clamping rod 7262 and is rotatably connected to the connecting sleeve 71. The clamping rod 7262 passes through the positioning port 711, and the other end of the clamping rod 7262 abuts against the bottom of the table surface 2.

[0050] Specific implementation process: When fixing the vibration sensor 6, insert the connecting sleeve 71 into the mounting hole 21 near the screw 5. Before insertion, push the pushing block 725 with your finger. The pushing block 725 then moves the connecting rod 722 along the top of the connecting sleeve 71. While the connecting rod 722 moves, the connecting plate 723 and the fixing plate 721 further compress the connecting spring 724. At the same time, the connecting support rod 7261 at the bottom of the connecting rod 722 moves synchronously. When the two connecting... As the support rod 7261 moves and rotates, it drives the clamping support rod 7262 to rotate toward the connecting sleeve 71, thereby ensuring that the connecting sleeve 71 and the clamping support rod 7262 can be inserted into the mounting hole 21 until the two clamping support rods 7262 move to the bottom of the platform 2 and the mounting hole 21. Then, the push block 725 is released, and under the reverse elastic force of the connecting spring 724, one end of the clamping support rod 7262 moves further away from the connecting sleeve 71. At this time, one end of the two clamping support rods 7262 is located outside the mounting hole 21.

[0051] Subsequently, one hand secures the fixed housing 61 and the connecting sleeve 71, while the other hand rotates the locking sleeve 73. As the locking sleeve 73 rotates, it moves synchronously from the outside of the connecting sleeve 71 along the platform 2 until one side of the locking sleeve 73 abuts against the platform 2. At this point, the two clamping rods 7262 and the locking sleeve 73 quickly secure the connecting sleeve 71 to the mounting hole 21, thereby achieving a rapid and stable connection of the vibration sensor 6.

[0052] A secondary positioning mechanism 8 is provided on the outside of the fixed shell 61, and the secondary positioning mechanism 8 fixes the vibration sensor 6 to the screw 5.

[0053] Please see Figures 3 to 5 and Figures 9 to 10 The secondary positioning mechanism 8 includes an outer plate 81, a connector 82, and a locking member 83. One end of the outer plate 81 is fixedly connected to the fixed shell 61, and the other end of the outer plate 81 is fixedly connected to the connector 82. The connector 82 is connected to the screw 5. The outer plate 81 is provided with a guide port 811, and the locking member 83 is connected to the guide port 811.

[0054] The connector 82 includes an outer ring 821, an adjusting rod 822, and an arc plate 823. The outer ring 821 is fixedly installed at one end of the outer plate 81. The outer ring 821 is U-shaped. There are two adjusting rods 822, which slide through both sides of the outer ring 821 respectively. The outer side of the adjusting rod 822 is provided with external threads, and the outer thread of the adjusting rod 822 is connected to a locking bolt 824. The locking bolt 824 abuts against the screw 5. The end of the adjusting rod 822 near the screw 5 is fixedly connected to the arc plate 823, and the arc plate 823 is located outside the screw 5.

[0055] Specifically: Before inserting the connecting sleeve 71 into the mounting hole 21, the outer ring 821, which is U-shaped, is fitted onto the outside of the screw 5. After the connecting sleeve 71 and the mounting hole 21 are fixed together, one side of the arc plate 823 is then brought into contact with the outside of the screw 5, and the locking bolt 824 is tightened to further fix the outer ring 821 and the screw 5, thereby further fixing the vibration sensor 6.

[0056] The locking component 83 includes a locking rod 831, a locking sleeve 832, a pressing contact 833, and a contact detection component 9. The locking rod 831 is U-shaped and consists of a vertical end 8311 and a horizontal end 8312. The horizontal end 8312 is fixedly installed on the top of the vertical end 8311. The vertical end 8311 slides through the guide opening 811. The locking sleeve 832 is sleeved on the outside of the locking rod 831. A threaded hole is provided on one side of the locking sleeve 832, and a tightening bolt 834 is threadedly connected to the threaded hole. The locking rod 831 has a insertion hole corresponding to the position of the tightening bolt 834.

[0057] The pressing contact 833 is installed at the transverse end 8312, and the pressing contact 833 further secures the fixing bolt 52;

[0058] The contact detection element 9 is installed on the top of the vertical end 8311, and the contact detection element 9 is used to detect the connection status of the fixing bolt 52.

[0059] The pressing contact 833 includes a pressing plate 8331, a pressing rod 8332, and a buffer spring 8333. The pressing plate 8331 is arc-shaped and abuts against the fixing bolt 52. Multiple pressing rods 8332 are provided and are fixed around the pressing plate 8331. The pressing rods 8332 slide through the transverse end 8312. The buffer spring 8333 is sleeved on the outside of the pressing rod 8332, and the two ends of the buffer spring 8333 are fixedly connected to the pressing plate 8331 and the transverse end 8312, respectively.

[0060] The contact detection component 9 includes a contact steel plate 91, a side plate 92, a support 93, and a contact block 94. The contact steel plate 91 slides through the vertical end 8311. One end of the contact steel plate 91 is located outside the fixing bolt 52 and is in contact with the outside of the fixing bolt 52. The end of the contact steel plate 91 near the fixing bolt 52 is set with an inclined surface.

[0061] The side plate 92 is fixedly installed at one end of the contact steel plate 91, and the side plate 92 is connected to the support member 93. The support member 93 is installed at the vertical end 8311. The contact block 94 is fixedly installed on the outside of the contact steel plate 91. A pressure sensor 95 is installed at the vertical end 8311 and at the position corresponding to the contact block 94. A buzzer 96 is provided on the outside of the vibration table 1.

[0062] The support member 93 includes a support rod 931 and a support spring 932. There are two support rods 931, one end of each of the two support rods 931 is fixedly connected to the vertical end 8311, and the side plate 92 is slidably sleeved on the outside of the support rod 931. The support spring 932 is sleeved on the outside of the support rod 931, and the two ends of the support spring 932 are fixedly connected to the side plate 92 and the vertical end 8311 respectively.

[0063] Specific implementation process: In this embodiment, the stability of the connection between the locking rod 831 and the guide port 811 is ensured. Therefore, the locking rod 831 is provided with a plug hole at the position corresponding to the tightening bolt 834. Thus, each time the relative position between the locking rod 831 and the locking sleeve 832 is adjusted, the tightening bolt 834 is disengaged from the plug hole. Subsequently, the relative position between the locking rod 831 and the locking sleeve 832 is adjusted, and then the tightening bolt 834 and the locking sleeve 832 are locked together, thereby achieving the function of fixing the locking rod 831 and the locking sleeve 832.

[0064] Meanwhile, after adjusting the locking lever 831, the pressing plate 8331 at the horizontal end 8312 of the locking lever 831, under the reverse elastic force of the buffer spring 8333, further fixes the fixing bolt 52. When the fixing bolt 52 becomes loose or not tightened due to the vibration of the table 2 during long-term vibration testing of the parts, the contact steel plate 91 is inserted into the gap between the fixing bolt 52 and the adjusting pressure plate 51. At this time, the contact block 94 presses the pressure sensor 95, and the pressure sensor 95 sends an electrical signal to the controller. At this time, the buzzer 96 sounds an alarm.

[0065] At the same time, when the connecting parts at the vibration sensor 6 become loose from the platform 2 and the screw 5 respectively, the steel plate will detach from the outside of the fixing bolt 52 and move to the top of the fixing bolt 52. Under the reverse elastic force of the support spring 932, the contact block 94 will be released from the pressure sensor 95, and the buzzer 96 will sound an alarm.

[0066] Example 2

[0067] Please see Figures 6 to 7 Example 2 is a further supplement to Example 1: The inner support 74 includes two elastic plates 741. One end of each elastic plate 741 is fixedly connected to the outside of the connecting sleeve 71. The end of the elastic plate 741 near the connecting sleeve 71 is a bent end, and the other end of the elastic plate 741 is an open end. The locking sleeve 73 has a locking port on the side near the two elastic plates 741.

[0068] Thus, with the two elastic plates 741 in place, when the connecting sleeve 71 is inserted into the internal threaded sleeve 4, the two elastic plates 741 abut against the inner side of the internal threaded sleeve 4 due to their elastic force, thereby ensuring the stability of the connection between the connecting sleeve 71 and the internal threaded sleeve 4. At the same time, when the locking sleeve 73 moves along the outside of the connecting sleeve 71 until one end of the locking sleeve 73 abuts against the table surface 2, the locking port of the locking sleeve 73 contacts the elastic plate 741, and the locking port limits the elastic plate 741, causing the open ends of the two elastic plates 741 to move towards the outside of the connecting sleeve 71. The elastic plates 741 further limit the locking sleeve 73. At the same time, when the locking sleeve 73 loosens, the two elastic plates 741 can position the connecting sleeve 71 and the internal threaded sleeve 4, ensuring the stability of the connecting sleeve 71.
