DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to specific embodiments.

[0027] In the present utility model, unless otherwise expressly provided and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are for the purpose of better explaining the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0028] The utility model provides a monitoring device integrating a sensor and a turning tool, such as Figures 1 to 8 As shown, it includes a mounting base 1, a turning tool body 2, a rotation clamping mechanism 3, a vibration sensor 4 and a pressing mechanism 5. The rotation clamping mechanism 3 is provided on the mounting base 1 and can clamp the turning tool body 2 on the mounting base 1. The pressing mechanism 5 is provided on the mounting base 1 and can press the vibration sensor 4 on the mounting base 1.

[0029] The clamping mechanism 5 includes a cam handle 51, a stud 52, a movable pressure block 53, a slide column 54, a compression spring 55 and a tension spring 56. The movable pressure block 53 is provided with a movable through hole 531. One end of the stud 52 is connected to the mounting seat 1, and the other end passes through the compression spring 55 and the movable through hole 531 and is threadedly connected to the cam handle 51. Specifically, the stud 52 is threadedly connected to the mounting seat 1, and the two ends of the compression spring 55 respectively press against the mounting seat 1 and the movable pressure block 53. The mounting seat 1 is provided with a first mounting groove 11, a fixed column 12 and a slide groove 1 3. The vibration sensor 4 is installed in the first installation slot 11. The two ends of the tension spring 56 are respectively connected to the fixed column 12 and the sliding column 54. One end of the sliding column 54 is installed on the movable pressure block 53, and the other end is slidably connected to the slide slot 13. Specifically, the sliding column 54 is threadedly connected to the movable pressure block 53; the movable pressure block 53 is provided with a resisting block 532. The cam handle 51 includes a rotating shaft portion 511 threadedly connected to the stud 52, a cam portion 512 connected to the rotating shaft portion 511, and a handle portion 513. The cam portion 512 can contact the resisting block 532.

[0030] When the vibration sensor 4 needs to be installed, if the cam portion 512 is in contact with the abutting block 532 at this time, the cam portion 512 pushes the movable pressure block 53 open to fully expose the first installation groove 11, and the vibration sensor 4 can be placed in the vibration sensor 4. Then, the vibration sensor 4 is first placed in the first installation groove 11, and then the cam handle 51 is rotated to make the cam portion 512 leave the abutting block 532. At this time, the movable pressure block 53 approaches the vibration sensor 4. In the process of continuing to rotate the cam handle 51, the movable pressure block 53 moves toward the mounting seat 1 until the movable pressure block 53 can press the vibration sensor 4 tightly on the mounting seat 1, and then the rotation can be stopped. As long as the cam portion 512 does not contact the abutting block 532 when the movable pressure block 53 moves to a depth that can press the vibration sensor 4, then the movable pressure block 53 is in a position partially blocking the vibration sensor 4 under the action of the tension spring 56. There is overlap between the movable pressure block 53 and the vibration sensor 4. At this time, the movable pressure block 53 can press the vibration sensor 4, thereby completing the installation of the vibration sensor 4. When the movable pressure block 53 moves to a depth that can press the vibration sensor 4, and the cam portion 512 just contacts the abutting block 532, the movable pressure block 53 is offset from the vibration sensor 4, and the movable pressure block 53 cannot press the vibration sensor 4. In this case, the clamping position of the movable pressure block 53 can only be adjusted by adding other items as pads, but this does not prevent the present embodiment from achieving the function of clamping the vibration sensor 4. By installing the vibration sensor 4 on the mounting base 1 in the above-mentioned installation method, the disassembly and installation of the vibration sensor 4 is more convenient, stable and durable, and effectively avoids the adsorption of chips and additional vibration interference caused by the magnetic base, thereby ensuring the accuracy of the monitoring signal; at the same time, the above-mentioned installation method can also adapt to vibration sensors 4 of different thicknesses, thereby improving the versatility and flexibility of the device.

[0031] In the embodiment, the mounting base 1 is provided with a mounting cavity 14, a mounting hole 15 and a threaded hole 16, the mounting cavity 14 is provided with a first limiting groove 141, the turning clamp mechanism 3 includes a clamp block 31 and a clamp driving assembly, the clamp block 31 is arranged in the mounting cavity 14, the clamp driving assembly is connected to the clamp block 31 after being screwed with the threaded hole 16, and the clamp driving assembly can drive the clamp block 31 to descend to clamp the mounting end 21 of the turning tool body 2 in the first limiting groove 141. When the turning tool body 2 needs to be installed, first, the mounting end 21 of the turning tool body 2 is placed in the mounting cavity 14 and at the first limiting groove 141, then the clamp driving assembly is rotated to make the clamp block 31 descend until the mounting end 21 of the turning tool body 2 is pressed against the mounting base 1, and the rotation is stopped, so that the installation of the turning tool body 2 is completed. The turning clamp mechanism 3 is used to replace the traditional bolt fastening mode, the quick installation and removal of the turning tool body 2 is realized, and the installation time is significantly shortened.

[0032] In the embodiment, the clamp block 31 is provided with a second limiting groove 311, and when the clamp block 31 clamps the mounting end 21, the upper part of the mounting end 21 is located in the second limiting groove 311. The second limiting groove 311 is arranged to further avoid the mounting end 21 from being deviated during clamping or after clamping, and the stability of the turning tool body 2 is improved.

[0033] In the embodiment, the clamp driving assembly includes a rotating handle 32 and a rotating screw 33, the rotating screw 33 includes a first threaded column 331, a second threaded column 332 and a clamp block 333 connected in sequence, the first threaded column 331 is screwed with the rotating handle 32, and the first threaded column 331 is screwed with the rotating handle 32 and is reinforced by using thread glue, so that the rotating handle 32 and the rotating screw 33 are completely fixed, the second threaded column 332 is screwed with the threaded hole 16, and the clamp block 333 is rotatably connected to the clamp block 31. Specifically, the rotating handle 32 is Z-shaped, in the rotating process, the Z-shaped rotating handle 32 is more labor-saving and convenient to operate, and the operation stability is improved. Of course, the rotating handle 32 can also be L-shaped or the like, and can be rotated.

[0034] In this embodiment, the clamping block 31 is provided with a connecting block 312. The connecting block 312 is provided with a side opening 3121 and an upper opening 3122 connected to the side opening 3121. The side opening 3121 and the upper opening 3122 form a mutually connected clamping groove 3123 within the connecting block 312. The clamping groove 3123 is in an inverted T-shape, and the clamping block 333 can enter the clamping groove 3123 from the side opening 3121. This structural design achieves a detachable connection between the clamping drive assembly and the connecting block 312. When the clamping drive assembly is damaged and needs to be replaced, only the damaged portion needs to be replaced, without replacing the entire assembly, thereby reducing maintenance costs.

[0035] In this embodiment, the mounting seat 1 is provided with an isolation cover 6 at the mounting hole 15 . The isolation cover 6 can effectively prevent chips from entering the mounting cavity 14 and avoid chips from accumulating in the mounting cavity 14 .

[0038] In this embodiment, the integrated sensor and turning tool monitoring device also includes a microstrain sensor 7. The mounting base 1 is provided with a second mounting slot 18, and the microstrain sensor 7 is mounted in the second mounting slot 18. Specifically, the microstrain sensor 7 is mounted in the second mounting slot 18 via bolts. Conventional microstrain sensors 7 are mounted directly on the side of the tool bar, requiring repeated drilling or tapping of the high-hardness tool bar, and requiring new drilling when the tool bar is replaced. However, the microstrain sensor 7 in this embodiment is mounted in the second mounting slot 18 via bolts, eliminating the need for repeated drilling and reducing processing costs and difficulty.

[0039] In this embodiment, the mounting base 1 is further provided with a second wire groove 19 communicating with the second mounting groove 18 . The second wire groove 19 is used for accommodating the connecting wires of the micro strain sensor 7 .

[0040] The arrangement of the first wire slot 17 and the second wire slot 19 in the above structure can eliminate the risk of wires being suspended or entangled, ensuring the connection security between the vibration sensor 4 and the microstrain sensor 7 and the acquisition system. Specifically, the connecting wires can be fixed by wire clips, of course, other methods can also be used for fixing.

[0041] In summary, this monitoring device integrating a sensor and a turning tool can solve the problem in the prior art that the vibration sensor is adsorbed on the surface of the tool rod through a magnetic base, generating additional vibration signals and causing signal aliasing.

[0042] In the absence of conflict, the above embodiments and features therein may be combined with each other.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
