Description

Technical Field

[0001] This utility model relates to the field of vibration acquisition equipment technology, and more specifically, to a clamping device for a vibration sensor. Background Technology

[0002] When collecting vibration data from equipment, a vibration data acquisition device needs to place the vibration sensor at the designated acquisition point. The sensor is typically attached to the acquisition point by a magnet. It usually needs to collect vibration information in three mutually perpendicular directions at the acquisition point. However, some acquisition points are inconvenient to operate manually or pose safety risks. Therefore, a clamping device is usually required to place the sensor at the acquisition point.

[0003] In other fields, there are clamping devices that facilitate extending the gripping stroke. Such clamping devices generally include a clamping head, a handhold, and a clamping drive component located on the clamping head and the handhold. By manually operating the clamping drive component, the movement between the two clamping jaws in the clamping head can be controlled, thereby enabling the clamping jaws in the clamping head to open or close.

[0004] For example, Chinese patent application No. 2015101405601 discloses a handheld torreya nut harvester with a scope, which includes a hollow rod, a handle, a front clamp, a rear clamp, an upper clamp, and a lower clamp. The upper and lower clamps are provided with inwardly extending sections, and each extension section has an elongated hole for mounting a traction pin. One end of the traction pin is connected to a pull line, and the other end of the pull line passes through the hollow rod and is fixed to the handle by a pulley. A spring is provided between the extension section and the left end of the hollow rod. By pulling the handle, the upper and lower clamps can grab the torreya nut without the harvester having to climb to the branch.

[0005] Although this type of clamping device can extend the clamping stroke, the relative angle between the clamping head and the hand-held part cannot be adjusted. In other words, the relative angle between the clamped object and the hand-held part cannot be adjusted, which makes it inconvenient to adjust the vibration sensor to three mutually perpendicular directions. Therefore, it is not convenient to collect vibration data at the three mutually perpendicular sampling points. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] To address the technical problem that existing clamping devices are inconvenient for adjusting vibration sensors to three mutually perpendicular directions for vibration data acquisition, this invention provides a clamping device for vibration sensors. This solution optimizes the installation and rotation direction of the clamp base, allowing the adjustment of the clamp base relative to the connecting rod and the rotation of the connecting rod around its own axis to move the sensor held by the clamp base in three mutually perpendicular directions.

[0008] 2. Technical solutions adopted

[0009] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0010] This utility model discloses a clamping device for a vibration sensor, comprising: a connecting rod; a clamping base rotatably mounted on one end of the connecting rod with its rotation axis perpendicular to the connecting rod, and having a clamping part for clamping the vibration sensor; and a clamping head traction mechanism for controlling the opening and closing of the clamping part.

[0011] Furthermore, a mounting hole perpendicular to the connecting rod is machined on one side of the top of the connecting rod, and a connecting protrusion that rotatably engages with the mounting hole is provided on one side of the fixture base.

[0012] Furthermore, the top of the connecting rod is provided with a connecting hole that is perpendicular to and communicates with the assembly hole, and the surface of the connecting protrusion is provided with an annular groove distributed along its circumference. The fixing member passes through the connecting hole and the annular groove in sequence to tighten the clamp base.

[0013] Furthermore, the connecting hole is a threaded hole, and the fixing component is an externally threaded fixing pin.

[0014] Furthermore, the clamping part includes an upper clamping head and a lower clamping head, and the clamping base is provided with a sliding groove, wherein at least one of the upper clamping head and the lower clamping head is slidably nested in the sliding groove.

[0016] Furthermore, the upper clamping head includes a grooved connecting plate and two upper clamping teeth. One side of the grooved connecting plate is slidably nested in the sliding groove, and the two upper clamping teeth are distributed parallel and spaced apart on the other side of the grooved connecting plate. The upper clamping teeth have an arc-shaped structure, and their bottom ends are arc-shaped clamping surfaces that match the outer diameter of the sensor. The lower clamping head is provided with lower clamping teeth corresponding to the upper clamping head.

[0017] Furthermore, the clamping surface of the upper clamping teeth is provided with a pad that matches its shape.

[0018] Furthermore, the connecting rod is provided with a first traction channel inside; the outlet end of the first traction channel forms an assembly hole; the clamp base is provided with a second traction channel passing through the connecting protrusion, the outlet end of the clamp base is connected to the inlet end of the second traction channel, and the clamp traction mechanism passes through the first traction channel and the second traction channel to drive the clamping part to open and close.

[0019] Furthermore, the clamp traction mechanism includes a fixed rod, a rotating rod, and a traction rope. One end of the fixed rod is fixed to the outside of the connecting rod, and the other end is hinged to the middle of the rotating rod.

And / or the second traction channel is an L-shaped channel, and the turns in the L-shaped channel are both right angles.

[0020] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0021] (1) This utility model optimizes the rotational installation method of the clamp base and the connecting rod. Specifically, it can be rotatably installed at one end of the connecting rod, and the rotation axis is perpendicular to the connecting rod. By adjusting the rotation of the clamping device along the axis of the connecting rod and adjusting the rotation of the clamp base relative to the connecting rod, the sensor held by the clamp base can be moved to three mutually perpendicular directions. In addition, by adding a connecting rod and a clamp traction mechanism, the clamping part is opened and closed by controlling the clamping mechanism, and the clamping stroke of the sensor is extended, so as to facilitate its placement at the collection point where it is inconvenient for manual operation.

[0022] (2) This utility model further optimizes the design of the clamping part. Specifically, in the upper clamping head, two upper clamping teeth are distributed parallel and spaced apart on the groove connecting plate. This helps prevent interference between the upper clamping teeth and the object to be detected during the process of placing the sensor in the designated position. Furthermore, the upper clamping teeth have an arc-shaped structure, and their bottom ends have arc-shaped clamping surfaces that match the outer diameter of the sensor, which helps improve the stability of the sensor clamping. Even further, the clamping surfaces of the upper clamping teeth are provided with pads that match their shape, which helps improve the stability of the sensor clamping. Attached Figure Description

They are not intended to limit the scope of the invention and therefore have no substantial technical significance.

[0042] This utility model provides a clamping device for a vibration sensor, see reference. Figure 1 , Figure 2 , Figure 6 As shown, the clamping device includes a connecting rod 3, a clamp base 4, the clamp base 4 being rotatably mounted on one end of the connecting rod 3 with its rotation axis perpendicular to the connecting rod 3, and having a clamping part for clamping a vibration sensor; and a clamp traction mechanism 5, which controls the opening and closing of the clamping part.

[0043] By adding a connecting rod 3 and a clamping traction mechanism 5, the clamping stroke of the sensor is extended, making it easier to place it at data collection points that are inconvenient for manual operation. More importantly, by adjusting the rotation of the clamping device along the axis of the connecting rod 3 and adjusting the rotation of the clamp base 4 relative to the connecting rod 3, the sensor held by the clamp base 4 can be moved in three mutually perpendicular directions.

[0044] The specific usage method of the clamping device is as follows: (1) Hold one end of the connecting rod 3, operate the clamp traction mechanism 5 to control the clamping part to open, place the sensor in the clamping part, operate the clamp traction mechanism 5 to control the clamping part to close, confine the sensor in the clamping part, manually drive the connecting rod 3 to move the sensor in the clamping part to the vicinity of the collection point; operate the clamp traction mechanism 5 to control the clamping part to open, the sensor is attracted to the first designated position by the magnet, and the vibration information in the first direction is collected.

[0045] (2) After the vibration information in the first direction is collected, manually drive the connecting rod 3 to move the clamping part to the sensor placement position, operate the clamp traction mechanism 5 to control the clamping part to open, grab the sensor, manually drive the connecting rod 3 to rotate 90° around its axis to change the orientation of the sensor, manually drive the connecting rod 3 to move the sensor in the clamping part to the vicinity of the collection point; operate the clamp traction mechanism 5 to control the clamping part to open, and the sensor is attracted to the second designated position by the magnet to collect vibration information in the second direction;

[0046] (3) After the vibration information in the second direction is collected, manually drive the connecting rod 3 to move the clamping part to the sensor placement position, operate the clamp traction mechanism 5 to control the clamping part to open, grab the sensor, and then adjust the clamp base 4 to rotate 90° around its own rotation axis; change the orientation of the sensor, manually drive the connecting rod 3 to move the sensor in the clamping part to the vicinity of the collection point; operate the clamp traction mechanism 5 to control the clamping part to open, and the sensor is attracted to the third designated position by the magnet to collect the vibration information in the third direction;

[0047] (4) After the vibration information in the third direction is collected, manually drive the connecting rod 3 to move the clamping part to the sensor placement position, operate the clamping traction mechanism 5 to control the clamping part to open and grab the sensor.

[0048] The first, second, and third directions are orthogonal to each other, thus completing the acquisition of vibration information in three directions at the acquisition point.

[0049] For details, please refer to Figure 2 , Figure 3 As shown, a mounting hole perpendicular to the connecting rod 3 is machined on one side of the top, and a connecting protrusion 401 that rotatably engages with the mounting hole is provided on one side of the fixture base 4.

[0050] More specifically, the top of the connecting rod 3 is provided with a connecting hole that is perpendicular to the assembly hole, and the surface of the connecting protrusion 401 is provided with an annular groove distributed along its circumference. The fixing member 6 passes through the connecting hole and the annular groove in sequence to tighten the clamp base 4.

[0051] More preferably, the annular groove extends 360° around the circumference of the connecting protrusion 401, so that the position of the fixing member 6 relative to the annular groove can be adjusted 360° around the circumference, thereby driving the clamp base 4 to rotate 360° around the mounting hole in the connecting rod 3.

[0052] As an extension, the connecting hole is a threaded hole, and the fixing part 6 is an externally threaded fixing pin. The specific process of adjusting the rotation of the connecting rod 3 and the clamp base 4 is as follows: loosen the fixing part 6, rotate the clamp base 4, adjust the clamp base 4 to rotate 90° relative to the adjusting connecting rod 3 around its outlet end, and then tighten the fixing part 6 to lock the relative position between the connecting rod 3 and the clamp base 4.

[0053] As a preferred embodiment of the clamping part, refer to Figure 2 , Figure 7 As shown, the clamping part includes an upper clamping head 1 and a lower clamping head 2. The clamping base 4 is provided with a sliding groove 403, and at least one of the upper clamping head 1 and the lower clamping head 2 is slidably nested in the sliding groove 403. The clamping head traction mechanism 5 is used to drive the upper clamping head 1 and the lower clamping head 2 to move relative to each other along the sliding groove 403.

[0054] When the clamping part is closed, in order to maintain the clamping force between the upper clamping head 1 and the lower clamping head 2, refer to Figure 5 As shown, a spring 8 is provided between the upper clamping head 1 and the lower clamping head 2, and the two ends of the spring 8 are fixedly connected to the adjacent inner sides of the upper clamping head 1 and the lower clamping head 2, respectively. Preferably, the axis of the spring 8 is parallel to the direction of movement of the upper clamping head 1 relative to the lower clamping head 2.

[0055] In some embodiments, reference Figure 7 , Figure 8As shown, the upper clamping head 1 includes a grooved connecting plate 101 and two upper clamping teeth 102. One side of the grooved connecting plate 101 is slidably nested in the sliding groove 403, and the two upper clamping teeth 102 are distributed parallel to each other on the other side of the grooved connecting plate 101. The upper clamping teeth 102 have an arc-shaped structure, and their bottom ends are arc-shaped clamping surfaces that match the outer diameter of the sensor. The lower clamping head 2 has lower clamping teeth corresponding to the upper clamping head 1. The two upper clamping teeth 102 are spaced apart, which helps to increase the distance between the two upper clamping teeth 102, thereby improving the stability of the sensor clamping. Moreover, during the process of placing the sensor in the designated position, the gap between the two upper clamping teeth 102 forms a clearance groove, which helps to prevent interference between the upper clamping teeth 102 and the object to be detected. Further preferably, one side of the lower clamping head 2 is fixedly installed on the fixture base 4.

[0056] More preferably, the clamping surface of the upper clamping tooth 102 is provided with a pad 7 that matches its shape. The pad 7 is preferably made of rubber material, which can reduce wear on the sensor on the one hand, increase the clamping force on the sensor on the other hand, and is beneficial for clamping sensors with irregular shapes.

[0057] In some other embodiments, the connecting rod 3 is further provided with a first traction channel 301 inside; the outlet end of the first traction channel 301 forms an assembly hole; the clamp base 4 is provided with a second traction channel 402 passing through the connecting protrusion 401, the outlet end of the clamp base 4 is connected to the inlet end of the second traction channel 402, and the clamp traction mechanism 5 passes through the first traction channel 301 and the second traction channel 402 to drive the clamping part to open and close.

[0058] For details, please refer to Figure 4 As shown, the clamp traction mechanism 5 includes a fixed rod 502, a rotating rod 501, and a traction rope 504. One end of the fixed rod 502 is fixed to the outside of the connecting rod 3, and the other end is hinged to the middle of the rotating rod 501. One end of the traction rope 504 is fixedly connected to one end of the rotating rod 501, and the other end is fixedly connected to the clamping part.

[0059] The rotating rod 501 acts as a handle; by gripping the rotating rod 501, [reference] Figure 4 From the perspective shown, the rotating rod 501 rotates counterclockwise, thereby pulling the upper clamping head 1 upward and causing the upper clamping head 1 to move away from the lower clamping head 2, thus realizing the opening and closing of the clamping part.

[0060] Preferably, one end of the fixing rod 502 is fixed to the outside of the connecting rod 3 and is located near the entrance end of the first traction channel 301.

[0061] In a preferred embodiment of the first traction channel 301, the first traction channel 301 is a Z-shaped channel, and both turns in the Z-shaped channel are right angles. Specifically, the first traction channel 301 includes an inlet end, an outlet end, and a middle section. The middle section is parallel to the axis of the connecting rod 3. The inlet end and the outlet end of the first traction channel 301 are located on both sides of the middle section. The inlet end and the outlet end of the first traction channel 301 are parallel to each other. Each turn is provided with a pulley 503 for guiding the traction rope 504. The pulley 503 is used to guide the direction of the traction rope 504. The Z-shaped channel, in conjunction with the pulley 503, can stabilize the direction of the traction rope 504, thereby allowing the traction rope 504 to smoothly drive the clamping part to open and close.

[0062] In a preferred embodiment of the second traction channel 402, the second traction channel 402 is an L-shaped channel, and the turns in the L-shaped channel are at right angles. Specifically, the entrance end of the second traction channel 402 is flush with the exit end of the first traction channel 301, and the traction rope 504 extends from the exit end of the second traction channel 402 and is fixedly connected to the clamping part.

[0063] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
