Since it is the existing technology, it will not be described in detail in this case. A pressure sensor is provided in the top 7, which can measure the size of the tightening force and can be presented in the form of data. The outer wall of the mounting seat 4 is provided with a correction assembly, which can quickly correct the installation position of the top 7, and the outer wall of the mounting seat 4 is provided with an anti-loosening assembly. The anti-loosening assembly can prevent the device from loosening due to vibration during the operation of the machine tool, thereby ensuring the stability of the device.

[0031] Reference Figure 1 - Figure 3 The correction component includes a moving ring 51, a positioning ring 52 is fixedly connected to the right surface of the moving ring 51, the inner diameter of the positioning ring 52 is slightly larger than the moving ring 51, the inner wall of the positioning ring 52 does not contact the mounting seat 4, and a slot 503 is provided on the outer wall of the top 7. A block 53 is penetrated and slidably connected to the upper surface of the mounting seat 4. The slot 503 and the block 53 fit together. When the positioning ring 52 moves to the right, it squeezes the left surface of the block 53. The outer wall of the mounting seat 4 is elastically connected with a protrusion 54 through a compression spring 55. There are multiple groups of slots 503, and there are multiple groups of protrusions 54, blocks 53 and compression springs 55. The multiple groups of slots 503, protrusions 54, blocks 53 and compression springs 55 are arranged in a circular array with the center of the positioning ring 52 as the origin.

[0032] Reference Figure 1 - Figure 3 The driving component also includes a motor 21. The motor 21 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The motor 21 is arranged on the left surface of the base 1. The output shaft of the motor 21 is fixedly connected to the screw 22. After the motor 21 is started, it can drive the screw 22 to rotate. The screw 22 penetrates and is rotatably connected to the left surface of the base 1. The screw 22 penetrates and is threadedly connected to the right surface of the moving block 23. When the screw 22 rotates, it can drive the moving block 23 to move horizontally.

[0033] Reference Figure 1 - Figure 3The anti-loosening component includes a limit groove 601, and there are multiple groups of limit grooves 601. The multiple groups of limit grooves 601 are arranged in a circular array with the center of the mounting seat 4 as the origin. The inner wall of the movable ring 51 is elastically connected to the limit block 61 through the connecting spring 63. The upper surface of the limit block 61 is fixedly connected with a pull ring 62. The pull ring 62 is convenient for pulling. Pulling the pull ring 62 can drive the limit block 61 to move synchronously.

[0034] Reference Figure 1 - Figure 3 The moving block 23 is set to an I-shape, and the moving block 23 is slidably connected to the upper surface of the base 1. The outer wall of the mounting seat 4 is provided with an external thread 501, and the inner wall of the moving ring 51 is provided with an internal thread 502. The external thread 501 and the internal thread 502 fit together. The limit block 61 passes through the lower surface of the external thread 501. The moving ring 51 is connected to the outer wall of the mounting seat 4 through the matching threads of the external thread 501 and the internal thread 502. The thread lead angle on the external thread 501 and the internal thread 502 is less than five degrees, which has a self-locking effect and can prevent the lateral force from causing the moving ring 51 to move lateral. The left end of the upper surface of the block 53 is set as an inclined surface. When the inclined surface of the block 53 is squeezed, the block 53 will move downward. When the block 53 moves downward, it will be inserted into the inner wall of the slot 503, so that the position of the top 7 can be corrected and fixed. The left surface of the protrusion 54 is fixedly connected to the top of the right surface of the block 53. The protrusion 54 and the block 53 will move synchronously. One end of the compression spring 55 is fixedly connected to the upper surface of the mounting seat 4, and the other end of the compression spring 55 is fixedly connected to the lower surface of the protrusion 54. When the protrusion 54 moves downward, it will squeeze the compression spring 55 to generate a reaction force.

[0035] Reference Figure 1 - Figure 3 The limit groove 601 is opened in a triangle shape, with one side being an inclined surface and the other side being a straight surface. The limit block 61 is approximately T-shaped, and the rear end of the lower surface of the limit block 61 is set to an inclined surface. When the moving ring 51 rotates, the inclined surface of the limit block 61 will contact the inclined surface of the limit groove 601, and the limit block 61 will be squeezed and move upward and disengage from the limit groove 601 to release the limit. When rotating in the opposite direction, the inclined surface of the limit block 61 will not be squeezed, and the limit block 61 cannot disengage from the limit groove 601 to release the limit. The limit block 61 is inserted into the inner wall of the limit groove 601, and the limit block 61 passes through and is slidably connected to the upper surface of the moving ring 51, sliding longitudinally. One end of the connecting spring 63 is fixedly connected to the inner wall of the bottom end of the moving ring 51, and the other end of the connecting spring 63 is fixedly connected to the lower surface of the limit block 61. When the limit block 61 moves upward, the connecting spring 63 is stretched to generate a reaction force.

[0036] Working principle: When using this device, first align the top 7 with the mounting seat 4 and plug it in. After plugging in, push the top 7 gradually to the left with one hand, and press the protrusion 54 downward with the other hand. When the slot 503 on the top 7 and the movable ring 51 are aligned, the protrusion 54 pressed by the hand will drive the block 53 to move downward and plug into the top 7 to complete the correction work. At this time, you can hold the top 7 steady with one hand, and rotate the movable ring 51 with the other hand, and then the movable ring 51 will move to the right, and the positioning ring 52 will also move to the right to squeeze the inclined surface of the block 53, and then multiple groups of blocks 53 will move toward the center of the mounting seat 4 and plug into the multiple groups of slots 503 on the outer wall of the top 7 to limit the top 7.

[0037] And during the rotation of the movable ring 51, the limit block 61 and the pull ring 62 will also rotate accordingly, and the inclined surface of the limit block 61 will be squeezed and then disengaged from the limit groove 601 to release the limit. When the fixation is completed, the limit block 61 will be plugged into the limit groove 601 to ensure the stability of the device and effectively prevent loosening.

[0038] Then the device can be used to measure the tightening force. When the top 7 needs to be disassembled, the pull ring 62 is pulled to drive the limit block 61 to move. When the limit block 61 moves, it will disengage from the limit groove 601 to release the limit, and will stretch the connecting spring 63 to generate a reaction force. At this time, the movable ring 51 can be reversed and loosened to release the squeezing of the block 53. Under the push of the reaction force of the compression spring 55, the protrusion 54 will move upward and disengage from the groove 503 to release the limit on the top 7, so that the top 7 can be disassembled.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
