[0002] Vibration testing is used to test the fatigue of some products after they are produced. Vibration testing is a type of fatigue testing. It mainly tests whether the internal structure of the product will change under long-term vibration. For example, in the patent number "CN219914805U" and the patent name "A kind of automobile muffler vibration testing platform", two positioning plates are fixedly connected to the positioning plates by springs; two supporting plates are respectively fixedly connected to the positioning plates vertically, and the supporting plates have positioning grooves; two clamping plates are respectively liftable and arranged on the two supporting plates, and are used to clamp the automobile muffler in the positioning groove; a connecting plate, two The ends are fixedly connected to the positioning plates respectively; a vibrator is fixedly connected to the connecting plate, the muffler is placed in the two positioning grooves, and then the muffler is clamped in the positioning groove by the vertical movement of the clamping plate, and then the cover moves downward, the open end is docked with the enclosure plate to form a test space, and then the vibrator is started intermittently, the vibrator is started for a short time, and the vibration is transmitted to the automobile muffler through the connecting plate, the positioning plate, and the support plate. Due to the presence of the spring, the vibration amplitude of the positioning plate can be increased. When the spring is stretched and exhausted, the vibrator is started again; a long-term fatigue life test is realized, but the above structure still has the following problems in actual use:

[0003] The above structure fixes the product through the clamp, but needs to operate one set of butterfly nuts separately for fixation, and then operate another set of butterfly nuts, which is very cumbersome, and the structure cannot clamp and fix columnar products, which makes its use limited.

[0004] Therefore, we proposed a clamping device for vibration detection of cylindrical products that can solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide a clamping device for vibration detection of columnar products, so as to solve the problem raised by the above-mentioned background technology that the current market needs to operate one set of butterfly nuts separately for fixing, and then operate another set of butterfly nuts, which is very cumbersome, and the structure cannot clamp and fix the columnar products, which makes it limited in use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A clamping device for vibration detection of a columnar product, comprising a bottom plate, a lower surface of which is fixedly mounted with table legs;

[0007] It also includes: a main board is arranged above the bottom plate, and a bidirectional screw rod is arranged on the right side of the main board, and the left end of the bidirectional screw rod penetrates into the inside of the main board, and the left end of the bidirectional screw rod is connected to the main board bearing, and the outer side surface of the bidirectional screw rod is provided with two sections of threads, and the two sections of threads are arranged in opposite structures;

[0008] The outer side surface of the bidirectional screw rod is threadedly connected with a sliding rod, and two groups of sliding rods are provided, and a clamping plate is fixed on the inner side of the upper end of the sliding rod.

[0009] Preferably, the clamping plate is arranged in an arc-shaped structure, and an anti-skid pad is bonded to the inner side of the clamping plate, and the anti-skid pad is made of rubber material.

[0010] Preferably, connecting side panels are fixed to the front and rear sides of the main board, and a sliding column is slidably connected through the middle of the connecting side panels.

[0011] Preferably, the connecting side panels are provided in two groups, and each group is provided with five.

[0012] Preferably, the lower end of the sliding column is fixed to the upper surface of the bottom plate, and a first spring is sleeved on the outer side of the lower end of the sliding column, and the lower end of the first spring is fixed to the upper surface of the bottom plate, and the upper end of the first spring is fixed to the connecting side plate.

[0013] Preferably, a second spring is sleeved on the upper end of the sliding column, and the upper end of the second spring is fixed to the sliding column, and the lower end of the second spring is fixed to the connecting side plate.

[0014] Preferably, a servo motor is bolted to the upper surface of the base plate, and the output end of the servo motor is fixed to the rotating shaft, and the right end of the rotating shaft is fixed to the cam, and the upper end of the cam is in contact with the protrusion, and the protrusion is fixed to the lower surface of the main board.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the clamping device for vibration detection of columnar products not only enables the clamping plate to clamp and fix the columnar products, but also has a simple and convenient operation process and good practicality. The anti-slip pad is made of rubber material, so that the clamping plate is more stable when clamping the columnar products and will not fall off due to vibration. At the same time, it can drive the main board to shake up and down, thereby achieving the effect of simulated vibration. The specific contents are as follows:

[0016] (1) The two sets of sliding rods are driven to move inward at the same time by the bidirectional screw rod, so that when the sliding rod moves inward, the clamping plate fixed thereto is driven to approach the columnar product. The arc-shaped structure of the clamping plate is set, so that the clamping plate can clamp and fix the columnar product. The operation process is simple and convenient, and the practicality is good.

[0017] Furthermore, an anti-skid pad is bonded to the inner side of the clamping plate, and the anti-skid pad is made of rubber material, so that the clamping plate is more stable when clamping the columnar product and will not fall off due to vibration;

[0018] By reversing the bidirectional screw rod, the bidirectional screw rod drives the two sets of slide rods to slide outward, and the slide rod drives the clamping plate away, thereby releasing the limit fixation of the columnar product, and then the columnar product can be taken down and a new columnar product can be put in;

[0019] (2) The cam rotates to push the protrusion and the main board upward, so that the main board drives the connecting side plate to squeeze the second spring, so that the second spring is in a force storage state. When the shaft drives the shaft to rotate until it is no longer in contact with the protrusion, the elastic force of the second spring drives the main board to shake up and down, thereby achieving a simulated vibration effect;

[0020] Furthermore, when the connecting side plate slides upward, the first spring will also be stretched. When the cam is not in contact with the bump, the tension of the first spring will also drive the side plate and the main plate to move up and down, thereby further increasing the elastic effect and making the vibration test more effective.

[0030] Embodiment 1: In order to solve the problem in the prior art that one set of butterfly nuts needs to be fixed separately and then another set of butterfly nuts needs to be fixed, which is very cumbersome, and the structure cannot clamp and fix columnar products, which makes it limited in use, the following scheme is disclosed, including a base plate 1, and a table leg is fixedly installed on the lower surface of the base plate 1; it also includes: a main board 6 is arranged above the base plate 1, and a bidirectional screw rod 7 is arranged on the right side of the main board 6, and the left end of the bidirectional screw rod 7 passes through the inside of the main board 6, and the left end of the bidirectional screw rod 7 is connected to the main board 6 bearing, and the outer side surface of the bidirectional screw rod 7 is provided with two sections of threads, and the two sections of threads are arranged in opposite structures; the outer side surface of the bidirectional screw rod 7 is threadedly connected with a sliding rod 8, and the sliding rod 8 is provided with two groups, and a clamping plate 9 is fixed on the inner side of the upper end of the sliding rod 8, and the clamping plate 9 is arranged in an arc structure, and an anti-skid pad 10 is bonded to the inner side of the clamping plate 9, and the anti-skid pad 10 is made of rubber material;

[0031] The two-way screw rod 7 is rotated to drive the two sets of sliding rods 8 to move inward at the same time, so that the sliding rod 8 moves inward, and the clamping plate 9 fixed thereto is driven close to the columnar product. The arc structure of the clamping plate 9 is set, so that the clamping plate 9 can clamp and fix the columnar product. At the same time, the inner side of the clamping plate 9 is bonded with an anti-skid pad 10, and the anti-skid pad 10 is made of rubber material, so that the clamping plate 9 is more stable when clamping the columnar product and will not fall off due to vibration. Moreover, the self-locking property of the thread also makes the clamping plate 9 clamp more firmly. The operation process is simple and convenient, and has good practicality. Moreover, when the inspection is completed, it is only necessary to reverse the two-way screw rod 7, so that the two-way screw rod 7 drives the two sets of sliding rods 8 to slide outward, so that the sliding rod 8 drives the clamping plate 9 away, thereby releasing the limit fixation of the columnar product, and then the columnar product can be taken down, and a new columnar product can be put in.

[0032] Embodiment 2: Different from Embodiment 1, this embodiment realizes the effect of simulating vibration. Figure 1-Figure 2 and Figure 6, the front and rear sides of the main board 6 are fixed with connecting side plates 5, and the middle of the connecting side plates 5 is slidably connected with a sliding column 2, two groups of connecting side plates 5 are provided, and each group is provided with five, the upper end of the sliding column 2 is sleeved with a second spring 4, and the upper end of the second spring 4 is fixed to the sliding column 2, and the lower end of the second spring 4 is fixed to the connecting side plate 5, the upper surface of the bottom plate 1 is bolted with a servo motor 11, and the output end of the servo motor 11 is fixed to the rotating shaft 12, and the right end of the rotating shaft 12 is fixed to the cam 13, and the upper end of the cam 13 is in contact with the protrusion 14, and the protrusion 14 is fixed to the lower surface of the main board 6;

[0033] By starting the servo motor 11, the servo motor 11 drives the rotating shaft 12 to rotate, and the rotating shaft 12 rotates, so that the rotating shaft 12 drives the fixed cam 13 to rotate, and the cam 13 rotates to contact the protrusion 14, and then the protrusion 14 is pushed up, so that the protrusion 14 drives the main board 6 to rise together, and then the main board 6 drives the connecting side plate 5 to slide up on the sliding column 2, so that the connecting side plate 5 squeezes the second spring 4, so that the second spring 4 is in a force storage state, when the rotating shaft 12 drives the rotating shaft 12 to rotate until it is not in contact with the protrusion 14, at this time, the elastic force of the second spring 4 drives the main board 6 to shake up and down, thereby achieving a simulated vibration effect;

When the cam 13 is not in contact with the protrusion 14, not only the elastic force of the second spring 4 can make the connecting side plate 5 and the main board 6 move up and down, but also the pulling force of the first spring 3 can drive the side plate 5 and the main board 6 to move up and down, thereby further increasing the elastic effect, so that the effect of the vibration test is better.
