DETAILED DESCRIPTION
[0030] The preferred technical solutions of the application are described in detail below in combination with the drawings.
[0031] Example 1: A variable frequency speed regulation all-in-one machine vibration amplitude detection device, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5The utility model relates to a kind of vibration transmission device, including installation rod 2, installation rod 2 is symmetrically installed on body 1, installation rod 2 can be detached, moving rod 8 is symmetrically slidably connected on installation rod 2, moving rod 8 has four, the outside of the moving rod 8 of front and rear sides is all fixedly connected with fixed rod 3, the top of two fixed rods 3 is all fixedly connected with push rod 4, the upper side of two push rods 4 is all inclined surface, the inside of the moving rod 8 of front and rear sides is all fixedly connected with contact plate 5 for conducting amplitude, the inside of each moving rod 8 is all covered with third spring 17, the both ends of third spring 17 are connected with contact plate 5 and installation rod 2 respectively, two installation rods 2 left side are fixedly connected with fixed frame 7, the upper portion of fixed frame 7 front and rear sides is all fixedly connected with connecting rod 6 for conducting amplitude, slidingly connected with moving frame 9 between two connecting rods 6, the bottom of moving frame 9 front and rear sides is all fixedly connected with guide rod 10, two guide rods 10 are slidably connected with shock-absorbing block 12 for receiving vibration on top, the bottom of two guide rods 10 lower portion is connected with first spring 11 with shock-absorbing block 12 bottom, moving frame 9 left side is fixedly connected with two guide rods 18, two guide rods 18 are slidably connected with guide frame 14, guide frame 14 upper portion is slidably connected with fixed frame 13, detector 16 is installed in fixed frame 13, the bottom left side of fixed frame 13 bottom is connected with two second springs 15 with guide frame 14 lower portion, the bottom of guide frame 14 is connected with the lower portion of two guide rods 18 with fourth spring 19.
[0032] In order to ensure the accuracy of the detection result, the vibration frequency of the machine body 1 can be detected, the mounting rod 2 is installed on the machine body 1, the connecting rod 6 is located on the top of the machine body 1 and is in contact with the machine body 1, when the vibration amplitude of the machine body 1 needs to be detected, the machine body 1 is started, the vibration generated during the operation of the machine body 1 drives the contact plate 5 to shake, and then the fixed rod 3 is driven to move by the moving rod 8, the third spring 17 is adaptively deformed, the fixed rod 3 drives the push rod 4 to move in and out, so that the push rod 4 pushes the moving frame 9 to move up and down, and then the moving frame 9 drives the shock block 12 to shake, and the connecting rod 6 is in contact with the machine body 1, so that the vibration frequency of the machine body 1 can be transmitted to the shock block 12, and the worker can manually press the detector 16 to move downward and contact the shock block 12, the fixed frame 13 is driven to move downward by the detector 16, and the second spring 15 is compressed. During the vibration of the moving frame 9, the fourth spring 19 is adaptively deformed to avoid the influence of the detector 16 on the vibration of the shock block 12 and the influence of the detection result. In this way, the vibration amplitude of the shock block 12 can be detected, so that the vibration amplitude of the machine body 1 can be detected. If the vibration is too violent, it indicates that the machine body 1 needs to be repaired. After the detection is completed, the second spring 15 is reset to drive the fixed frame 13 and the detector 16 to move upward and reset. The worker can also detect the local vibration of the machine body 1 according to the needs, manually control the moving frame 9 to move to the position to be detected, and then press the detector 16 to drive the shock block 12 to move downward. The first spring 11 is compressed so that the shock block 12 is in contact with the machine body 1. In this way, the specific local vibration can be detected to obtain more data and improve the detection accuracy. After the end, the first spring 11 is reset to drive the shock block 12 to move upward and reset. The detector 16 is reset under the reset action of the second spring 15, and then the moving frame 9 is controlled to reset.
[0033] Example 2: Based on example 1, please refer to Figure 6 and Figure 7 The sliding rod 20 is symmetrically connected to the fixed frame 7 in a sliding manner, the right side of each sliding rod 20 is a slope, the left upper side of the fixed frame 7 is fixedly connected with two support rods 21, the support rod 21 is L-shaped, the lower part of each support rod 21 is rotatably connected with a rotating block 22 for transmitting vibration amplitude, and the lower part of each support rod 21 is sleeved with a torsional spring 23, and the two ends of the torsional spring 23 are connected with the lower part of the support rod 21 and the rotating block 22 respectively.
[0034] In order to ensure the accuracy of the detection result, the amplitude conduction contact point can be increased, the rotating block 22 is in contact with the body 1, and when the body 1 vibrates, it will hit the rotating block 22 to rotate, and the torsional spring 23 will deform adaptively, so that the rotating block 22 pushes the sliding rod 20 to move to the right. If the moving distance of the sliding rod 20 is greater than the moving distance of the contact plate 5, it indicates that the amplitude of the left side of the body 1 is stronger than the middle part of the body 1, and the side with strong vibration can increase the moving distance of the push rod 4, thereby increasing the amplitude of the up-down shaking of the moving frame 9. In this way, the maximum value can be obtained in different amplitudes, which facilitates the detector 16 to detect the maximum vibration amplitude of the body 1, thereby improving the accuracy of the detection result and facilitating the staff to judge whether the body 1 needs to be repaired.
[0035] Please refer to Figure 8 and Figure 9 It also includes a fixed plate 25, two fixed plates 25 are respectively installed on the front and rear sides of the upper part of the body 1, the fixed plate 25 can be disassembled, and three sliding rods 24 are slidably connected to each of the two fixed plates 25. Each sliding rod 24 has a fifth spring 27 sleeved on the outer side, and the two ends of the fifth spring 27 are respectively connected to the sliding rod 24 and the outer side of the fixed plate 25. The three sliding rods 24 on the front side are fixedly connected with a contact block 26 for contacting the body 1, and the three sliding rods 24 on the rear side are fixedly connected with a contact block 26. The contact block 26 is arc-shaped.
[0036] In order to ensure the accuracy of the detection result, the contact block 26 is in close contact with the body 1, so that the surface of the body 1 can be completely fitted, avoiding the uneven surface of the body 1 affecting the detection value. When the body 1 vibrates, the contact block 26 vibrates, and the fifth spring 27 deforms adaptively, so that the more intuitive amplitude can be transmitted to the shock block 12, improving the detection effect.
[0037] Please refer to Figure 10 , Figure 11 and Figure 12 It also includes a placing rod 28, and the fixed frame 7 is fixedly connected with the placing rod 28 on the upper front and rear sides. The placing rod 28 is inclined, and the placing rod 28 is uniformly provided with a limiting groove 32. Two circular rings 29 are placed on the two placing rods 28, and the inner walls of the two circular rings 29 are fixedly connected with a clamping block 31 through two telescopic components 30. The clamping block 31 is in contact with the placing rod 28. The telescopic component 30 is composed of a telescopic rod and a spring. The telescopic rod is connected to the circular ring 29, and the spring is sleeved on the telescopic rod.
[0038] In order to more intuitively feel the vibration amplitude of the machine body 1, the position of the ring 29 can be observed. When the machine body 1 vibrates, the fixed frame 7 will vibrate, and then drive the placement rod 28 to vibrate. The vibration of the placement rod 28 drives the ring 29, the telescopic assembly 30 and the clamping block 31 to vibrate. The telescopic assembly 30 deforms adaptively. If the vibration is too violent, the ring 29 will move downward along the placement rod 28 during the vibration process. If the worker sees that the ring 29 descends too fast, the detector 16 can be used for detection immediately, and then it is judged whether to be repaired. The worker can conveniently repair the machine body 1 in time.
[0039] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process transformation using the content of the present application specification, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
