Description

Technical Field

[0001] The present invention relates to the technical field of automatic part vibration detection, and specifically to an automatic part vibration detection device. Background Technique

[0002] Automatic part vibration detection is mainly based on the principle of vibration testing. By simulating the vibration conditions in the actual working environment, the part is excited and its response is measured. According to the physical properties of the test, vibration testing methods can be mainly divided into three categories: electrical measurement method, optical measurement method, and mechanical measurement method;

[0003] At present, the mechanical measurement method for part vibration detection is to detect through a vibration test bench. The part is installed on the vibration test bench by means of screw pressing. At the same time, a vibration sensor is installed near the part. Since the parts to be detected are different each time, the existing vibration sensor is fixed on the vibration test bench by the glue pasting method. Although this method is convenient for the installation of the vibration sensor, when disassembling the vibration sensor, it is easy to cause damage to the vibration sensor. At the same time, after multiple pastings at the bottom of the vibration sensor, a large amount of glue will remain at the bottom, which will affect the installation of the vibration sensor and further affect the part vibration detection.

The positioning member 72 is used to tightly clamp the bottom of the connection sleeve 71 and the bottom of the table top 2;

[0045] External threads are arranged on the outer side of the top of the connection sleeve 71, and an internal thread hole is arranged at the top of the locking sleeve 73. The locking sleeve 73 is threadedly connected with the connection sleeve 71. In this embodiment, a plurality of rotating rods are arranged around the outer side of the locking sleeve 73, which is convenient for the staff to rotate the locking sleeve 73. The inner support member 74 is arranged on the outer side of the connection sleeve 71, and the inner support member 74 is staggered with the positioning port 711.

[0046] The positioning member 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 member 726. The fixing plate 721 is fixedly installed at the top inside the connecting sleeve 71. The connecting rod 722 slidably penetrates through the fixing plate 721, and the connecting plate 723 is fixedly sleeved on the outer side of the bottom of the connecting rod 722. The connecting spring 724 is sleeved on the outer side of the connecting rod 722, and the two ends of the connecting spring 724 are respectively fixedly connected to the fixing plate 721 and the connecting plate 723;

[0047] The pushing block 725 is fixedly installed at the top of the connecting rod 722, and one end of the pushing block 725 extends to the outside of the connecting sleeve 71. A moving port is provided at the position of the connecting sleeve 71 corresponding to the pushing block 725;

The connecting shaft 7263 is fixedly installed at one end of the clamping support rod 7262, and the connecting shaft 7263 is rotatably connected to the connecting sleeve 71. The clamping support rod 7262 penetrates through the positioning port 711, and the other end of the clamping support rod 7262 abuts against the bottom of the table 2;

[0050] Specific implementation process: When fixing the vibration sensor 6, at one installation hole 21 near the screw 5, insert the connecting sleeve 71 into the installation hole 21. Before insertion, use a finger to push the pushing block 725. The pushing block 725 drives the connecting rod 722 to move along the top inside the connecting sleeve 71. When the connecting rod 722 moves, the connecting spring 724 is further squeezed by the connecting plate 723 and the fixing plate 721. At the same time, the connecting support rod 7261 at the bottom of the connecting rod 722 moves synchronously. When the two connecting support rods 7261 move and rotate, they drive the clamping support rod 7262 to rotate towards the connecting sleeve 71, so as to ensure that the connecting sleeve 71 and the clamping support rod 7262 can be inserted into the installation hole 21 until the two clamping support rods 7262 move to the bottom of the table 2 and the installation hole 21. Then, release the pushing block 725. Under the reverse elastic force of the connecting spring 724, the end of the clamping support rod 7262 moves further along the direction away from the connecting sleeve 71. At this time, one end of the two clamping support rods 7262 is located outside the installation hole 21;

[0051] Subsequently, one hand fixes the fixed housing 61 and the connecting sleeve 71, and the other hand rotates the locking sleeve 73. While the locking sleeve 73 is rotating, it simultaneously moves along the tabletop 2 from the outside of the connecting sleeve 71 until one side of the locking sleeve 73 abuts against the tabletop 2. At this time, the connecting sleeve 71 and the mounting hole 21 are quickly fixed by the two clamping rods 72 and 62 and the locking sleeve 73, thereby realizing the quick and stable connection of the vibration sensor 6.

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

[0053] Please refer to Figures 3 to 5 and Figures 9 to 10 As shown in, the secondary positioning mechanism 8 includes an external connection plate 81, a connecting member 82, and a locking member 83. One end of the external connection plate 81 is fixedly connected to the fixed housing 61, and the other end of the external connection plate 81 is fixedly connected to the connecting member 82. The connecting member 82 is connected to the screw 5. A guiding opening 811 is provided on the external connection plate 81, and the locking member 83 is connected at the guiding opening 811.

[0054] The connecting member 82 includes an outer ring 821, an adjusting rod 822, and an arc-shaped plate 823. The outer ring 821 is fixedly installed at one end of the external connection plate 81. The outer ring 821 is U-shaped. There are two adjusting rods 822, and the two adjusting rods 822 respectively slide through both sides of the outer ring 821. External threads are provided on the outside of the adjusting rod 822, and a locking bolt 824 is threadedly connected to the outside of the adjusting rod 822.

One end of the adjusting rod 822 close to the screw 5 is fixedly connected to the arc-shaped plate 823, and the arc-shaped 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 in the shape of U is used to sleeved on the outside of the screw 5 correspondingly. Until the connecting sleeve 71 and the mounting hole 21 are fixed to each other, subsequently, one side of the arc-shaped plate 823 is abutted against the outside of the screw 5 respectively, and then the locking bolt 824 is tightened, so as to further fix between the outer ring 821 and the screw 5, and further realize the further fixation of the vibration sensor 6.

[0056] The locking member 83 includes a locking rod 831, a locking sleeve 832, a pressing contact member 833 and a contact detection member 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 at the top of the vertical end 8311. The vertical end 8311 slidably penetrates through the guiding opening 811, and the locking sleeve 832 is sleeved outside the locking rod 831. One side of the locking sleeve 832 is provided with a threaded hole, and a tightening bolt 834 is threadedly connected to the threaded hole. The locking rod 831 is provided with a plugging hole corresponding to the position of the tightening bolt 834;

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

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

[0059] The pressing contact member 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. A plurality of pressing rods 8332 are provided, and the plurality of pressing rods 8332 are circumferentially fixed on the pressing plate 8331. The pressing rod 8332 slidably penetrates through the horizontal end 8312. The buffer spring 8333 is sleeved outside the pressing rod 8332, and both ends of the buffer spring 8333 are fixedly connected to the pressing plate 8331 and the horizontal end 8312 respectively.

[0060] The contact detection member 9 includes a contact steel plate 91, a side plate 92, a support member 93 and a contact block 94. The contact steel plate 91 slidably penetrates through the vertical end 8311. One end of the contact steel plate 91 is located outside the fixing bolt 52 and contacts the outside of the fixing bolt 52. One end of the contact steel plate 91 close to the fixing bolt 52 is provided 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 outside the contact steel plate 91. A pressure sensor 95 is installed at the vertical end 8311 corresponding to the position of the contact block 94. A buzzer 96 is provided outside the vibration table frame 1.

[0062] The support member 93 includes a support rod 931 and a support spring 932. Two support rods 931 are provided.

The support spring 932 is sleeved outside the support rod 931, and both 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, to ensure the stability of the connection between the locking rod 831 and the guiding port 811, the locking rod 831 is provided with a plugging 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 plugging hole. Subsequently, the relative position between the locking rod 831 and the locking sleeve 832 is adjusted, and then the tightening bolt 834 is locked with the locking sleeve 832, thereby achieving the function of fixing the locking rod 831 and the locking sleeve 832.

[0064] Meanwhile, after the locking rod 831 is adjusted, the pressing plate 8331 at the lateral end 8312 of the locking rod 831, under the reverse elastic force of the buffer spring 8333, further fixes the fixing bolt 52. When the parts are undergoing vibration detection for a long time, with the vibration of the table 2, if the fixing bolt 52 becomes loose or is not tightened, the contact steel plate 91 is inserted into the gap between the fixing bolt 52 and the adjusting pressing 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, and the buzzer 96 gives an early warning.

[0065] Meanwhile, when the connecting components at the vibration sensor 6 become loose from the table 2 and the screw 5 respectively, the steel plate disengages from the outside of the fixing bolt 52 and moves to the top of the fixing bolt 52. Under the reverse elastic force of the support spring 932, the contact block 94 is disengaged from the pressure sensor 95, and at this time, the buzzer 96 gives an early warning.

[0066] Embodiment Two

[0067] Please refer to Figures 6 to 7 , Embodiment Two is a further supplementary description of Embodiment One: The inner support member 74 includes elastic plates 741. There are two elastic plates 741. One end of each of the two elastic plates 741 is fixedly connected to the outside of the connecting sleeve 71. The end of the elastic plate 741 close to the connecting sleeve 71 is a bent end, and the other end of the elastic plate 741 is a supporting end. The locking sleeve 73 is provided with a locking opening on one side close to the two elastic plates 741.

[0068] Thus, due to the arrangement of the two elastic plates 741, when the connecting sleeve 71 is inserted into the internal thread sleeve 4, the two elastic plates 741 are in contact with the inner side of the internal thread sleeve 4 under their elastic force, thereby ensuring the stability of the connection between the connecting sleeve 71 and the internal thread sleeve 4. At the same time, when the locking sleeve 73 moves along the outer side of the connecting sleeve 71 until one end of the locking sleeve 73 abuts against the tabletop 2, at this time, the locking port of the locking sleeve 73 contacts the elastic plate 741, and the locking port limits the elastic plate 741, causing the propping ends of the two elastic plates 741 to move towards the outer side of the connecting sleeve 71. Moreover, the elastic plate 741 further limits the locking sleeve 73. At the same time, when the locking sleeve 73 becomes loose, the two elastic plates 741 can position the connecting sleeve 71 and the internal thread sleeve 4, ensuring the stability of the connecting sleeve 71.

[0069] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0070] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
