Description

Technical Field

[0001] This utility model relates to the field of vibration detection, and in particular to a machine tool vibration detection device. Background Technology

[0002] In machining, machine tools inevitably vibrate because they need to be processed by cutting tools. In order to ensure machining quality, the vibration of the machine tool needs to be controlled within the allowable range.

[0003] Currently, machine tool vibration is typically detected using optical dynamic displacement sensors. These devices consist of a target and a camera (optical sensor). The target, serving as a reference point for vibration measurement, needs to be fixed to the vibrating part of the machine tool. The camera needs to be mounted detached from the machine tool. The camera continuously captures images of the target's movement, and image processing algorithms extract the target's center coordinates to obtain the machine tool's vibration status. In practical applications, the camera is usually fixed to an existing component next to the machine tool. However, due to the installation location, it may be difficult to align the camera with the target on the machine tool, requiring the welding of a bracket to the existing component. This is cumbersome, and if the detection position on the machine tool changes, the camera is inconvenient to adjust, necessitating the re-welding of the bracket.

[0004] Therefore, a technical solution is needed to address the problem that when a camera for vibration detection is installed on an existing component next to the machine tool, it is difficult to align the camera with the target and the camera position cannot be adjusted accordingly when the target position changes. Utility Model Content

[0005] The purpose of this invention is to overcome the technical problems in the prior art where a camera for detecting vibration is installed on an existing component next to the machine tool, making it difficult to align the camera with the target and to adjust the camera position accordingly when the target position changes. This invention provides a machine tool vibration detection device.

[0006] This utility model provides a machine tool vibration detection device, including a base, a support rod on the base, the support rod being able to extend or shorten, a mounting rod at the top of the support rod, a mounting hole for mounting a camera at the end of the mounting rod, a fastening screw hole communicating with the mounting hole on the side of the mounting rod, and a fastening bolt in the fastening screw hole for tightening onto the camera.

[0007] This utility model discloses a machine tool vibration detection device. In use, the base is placed near the machine tool and aligned with the position of the target on the machine tool. A cylindrical camera is embedded into the mounting hole at the end of the mounting rod and fixed with fastening bolts. The height of the support rod is adjusted so that the camera is aligned with the target on the machine tool, thus achieving alignment between the camera and the target on the machine tool. This facilitates the camera's ability to capture images of the target. Moreover, if the position of the target changes, only the position of the base needs to be moved, and the above steps can be repeated to adjust the position of the camera accordingly. The operation is simple.

[0008] Preferably, the support rod includes several telescopic segments, and adjacent telescopic segments are threadedly connected.

[0009] By rotating two adjacent telescopic segments relative to each other, the total length of the two adjacent telescopic segments can be adjusted, thereby adjusting the length of the support rod and thus adjusting the height of the camera mounted on the rod.

[0010] Preferably, the inner wall of the mounting hole is provided with a first elastic pad.

[0011] The first elastic pad provides initial positioning for the camera, preventing it from accidentally falling during installation. At the same time, the elastic pad provides some protection for the outer wall of the camera, reducing collision damage between the camera and the mounting components.

[0012] Preferably, the end of the fastening bolt that abuts against the camera is provided with a second elastic pad.

[0013] This ensures a soft contact between the fastening bolt and the camera, preventing damage to the camera housing during tightening.

[0014] Preferably, the base has several casters at its bottom.

[0015] The base allows for easy movement around the workshop and machine tools, making it more convenient and less labor-intensive to move and adjust the position of the testing device.

[0016] Preferably, the base is provided with at least three adjustment screw holes, all of which are evenly arranged around the support rod, and each adjustment screw hole is equipped with an adjustment screw.

[0017] When there are uneven surfaces such as pits or faults on the ground, the base can be raised using the adjusting screws to keep it stable and prevent inaccurate test data caused by base wobbling. Raising the base with the adjusting screws also prevents the casters from directly contacting the ground, acting as a brake to prevent the base from moving during the test.

[0018] Preferably, the mounting rod is rotatably connected to the support rod, and the support rod is provided with a limiting member to restrict the rotation of the mounting rod.

[0019] After adjusting the height of the mounting rod using the support rod, the camera may still not be aligned with the target. In this case, the camera's direction can be adjusted by rotating it laterally relative to the support rod, thereby enabling the camera to be aligned with the target on the machine tool and increasing the camera's adjustment range.

[0020] Preferably, the support rod has a fixed seat at the top, the fixed seat has a spherical groove at the top, the mounting rod has a rotating ball at the end that matches the spherical groove, the fixed seat has a limiting screw hole on the side that communicates with the spherical groove, and a limiting bolt is provided in the limiting hole. The limiting bolt is used to press against the outer wall of the rotating ball.

[0021] The mounting rod and support rod are rotatably connected, and the mounting rod and support rod are connected by a rotating ball and a spherical groove, which increases the range of adjustment of the mounting rod direction. When the support rod and the target are initially aligned, the camera can be aligned with the target by rotating the mounting rod on the support rod without the need for secondary adjustment of the base, making the operation simpler. After adjustment, the rotating ball and the fixed seat are relatively fixed by the limit bolts to prevent the camera from rotating during the detection process and affecting the detection accuracy.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This utility model provides a machine tool vibration detection device, which features a movable base, a support rod mounted on the base, a mounting rod at the bottom of the support rod, and a mounting bracket for mounting a camera at the end of the mounting rod. By adjusting the height of the support rod, the position of the base, and the height of the support rod, the camera can be aligned with a target on the machine tool. This simplifies camera installation and allows for adjustments based on changes in the position of the target. Attached Figure Description

However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0030] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0032] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Example 1

[0035] like Figure 1 and Figure 2 As shown, a machine tool vibration detection device includes a base 1, a support rod 2 on the base 1, the support rod 2 being able to extend or shorten, a mounting rod 3 at the top of the support rod 2, a mounting hole 31 at the end of the mounting rod 3 for mounting a camera 5, and a fastening screw hole 32 communicating with the mounting hole 31 on the side of the mounting rod 3, a fastening bolt 33 being fitted in the fastening screw hole 32, the fastening bolt 33 being used to tighten onto the camera 5.

[0036] In use, by placing the base 1 near the machine tool and aligning it with the position of the target on the machine tool, the cylindrical camera 5 is embedded into the mounting hole 31 at the end of the mounting rod 3. The camera 5 is then fixed by the fastening bolt 33. The height of the support rod 2 is adjusted so that the camera 5 is aligned with the target on the machine tool, thus achieving the alignment of the camera 5 with the target on the machine tool. This facilitates the camera 5 in taking pictures of the target. Moreover, when the position of the target changes, only the position of the base 1 needs to be moved, and the above steps can be repeated to make corresponding adjustments to the position of the camera 5. The operation is simple.

[0037] Support rod 2: includes several telescopic segments 21, with adjacent telescopic segments 21 threaded together. By rotating the two adjacent telescopic segments 21 relative to each other, the total length of the two adjacent telescopic segments 21 can be adjusted, thereby adjusting the length of the support rod 2, and thus realizing the adjustment of the height of the mounting rod 3 and the long camera 5.

[0038] Mounting rod 3: The inner wall of its mounting hole 31 is provided with a first elastic pad 34. The first elastic pad 34 has a preliminary limiting effect on the camera 5 to prevent the camera 5 from falling accidentally during the installation process. At the same time, the elastic pad has a certain protective effect on the outer wall of the camera 5, which can reduce the collision damage between the camera 5 and the mounting components. The end of the fastening bolt 33 that abuts against the camera 5 is provided with a second elastic pad 35, so that the fastening bolt 33 and the camera 5 have soft contact, which prevents the fastening bolt 33 from damaging the outer shell of the camera 5 during the tightening process.

[0039] Base 1: The bottom of base 1 is equipped with several casters 11, which facilitates the movement of base 1 around the workshop and machine tools, making the transfer and position adjustment of the testing device more convenient and less labor-intensive. Base 1 is provided with at least three adjustment screw holes, all of which are evenly arranged around the support rod 2. Each adjustment screw hole is equipped with an adjustment screw 12. When there are uneven conditions such as pits or faults on the ground, the base 1 can be raised by the adjustment screw 12 to keep the base 1 stable and avoid inaccurate test data caused by the shaking of the base 1. At the same time, raising the base 1 by the adjustment screw 12 can also prevent the casters 11 from directly contacting the ground, which acts as a brake and prevents the base 1 from moving during the testing process. Example 2

[0040] like Figure 1 and Figure 3 As shown, in this embodiment, the difference from embodiment 1 is that the mounting rod 3 is rotatably connected to the support rod 2, and the support rod 2 is provided with a limiting member to restrict the rotation of the mounting rod 3.

[0041] After adjusting the height of the mounting rod 3 using the support rod 2, the camera 5 may still not be able to align with the target. In this embodiment, the direction of the camera 5 can be adjusted by rotating it laterally relative to the support rod 2, thereby enabling the camera 5 to align with the target on the machine tool and increasing the adjustment range of the camera 5.

[0042] Specifically, the support rod 2 has a fixed seat 4 at its top, and the fixed seat 4 has a spherical groove 41 at its top. The mounting rod 3 has a rotating ball 36 at its end that is adapted to the spherical groove 41. The fixed seat 4 has a limiting screw hole 42 on its side that communicates with the spherical groove 41. A limiting bolt 43 is fitted in the limiting hole and is used to press against the outer wall of the rotating ball 36, thus realizing a rotatable connection between the mounting rod 3 and the support rod 2. Moreover, the mounting rod 3 and the support rod 2 are connected by the rotating ball 36 and the spherical groove 41, which increases the range of directional adjustment of the mounting rod 3. When the support rod 2 and the target are initially aligned, the camera 5 can be aligned with the target by rotating the mounting rod 3 on the support rod 2 without the need for secondary adjustment of the base 1, making the operation simpler. After adjustment, the limiting bolt 43 forms a relative fixation between the rotating ball 36 and the fixed seat 4, preventing the camera 5 from rotating during the detection process and affecting the detection accuracy.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
