[0029] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0030] Please see Figures 1 to 5 The present invention provides a multifunctional detection device, comprising a test head 1, a conductive component 2, a pressure sensing component 3, a torque sensing component 4, a control board 5, and a housing 6.

[0031] The conductive element 2 includes an intermediate plate 21, a rod 22 connected to the intermediate plate 21, and a clamping block 23. The intermediate plate 21 is connected to the housing 6, the rod 22 protrudes into the housing 6, and the test head 1 is rotatably connected to the rod 22.

[0032] The pressure sensing component 3 is located below the intermediate plate 21 and abuts against the intermediate plate 21;

[0033] The torque sensing component 4 is located below the intermediate plate 21 and is connected to the intermediate plate 21.

[0034] The detection device also includes a control board 5 installed on the housing 6, and the end of the torque sensing component 4 away from the intermediate plate 21 is connected to the control board 5.

[0035] Specifically, in this embodiment, the conductive member 2 includes a rod 22 and an intermediate plate 21 connected in sequence. The radial dimension of the intermediate plate 21 is consistent with the inner diameter of the housing 6. The intermediate plate 21 and the housing 6 are fixedly connected by screws. The rod 22 protrudes into the housing 6, and the free end of the rod 22 is connected to the test head 1. The test head 1 is rotatably connected to the rod 22. One end of the test head 1 is provided with a groove, and the free end of the rod 22 is embedded in the groove to achieve a stable connection. A clamping block 23 is provided on the other side of the intermediate plate 21. The clamping block 23 clamps the torque sensing component 4. The torque sensing component 4 is connected to the control... The control board 5 is electrically connected. The torque generated by the test head 1 and the external screw connection is transmitted to the control board 5 through the rod 22, the intermediate plate 21, the clamping block 23, and the torque sensing component 4, and finally displayed digitally to achieve real-time torque monitoring. At the same time, the pressure sensing component 3 is in contact with the intermediate plate 21. During operation, the pressure generated by the test head 1 and the external screw connection is transmitted to the pressure sensing component 3 through the rod 22 and the intermediate plate 21, and finally displayed digitally to achieve real-time pressure monitoring. This controls the magnitude of the external force applied by the electric screwdriver and ensures the pass rate of production quality.

[0036] Preferably, the clamping block 23 includes a left clamping piece 231 and a right clamping piece 232, both of which are L-shaped and connected to the intermediate plate 21. The left clamping piece 231, the right clamping piece 232, and the intermediate plate 21 form a cavity 2301. The free ends of the left clamping piece 231 and the right clamping piece 232 are spaced apart to form a gap 2302. The end of the torque sensing component 4 closest to the conductor 2 is clamped in the gap 2302. The pressure on the rod 22 is transmitted to the torque sensing component 4 through the left clamping piece 231, the right clamping piece 232, and the intermediate plate 21, realizing instantaneous torque sensing and improving sensing sensitivity. Furthermore, the cavity 2301 is used to house the pressure sensing component 3, making the connection structure of the conductor 2, the pressure sensing component 3, and the torque sensing component 4 more rational and reducing the overall volume of the detection device.

[0037] By setting up a test head 1, a transmission rod 2, a pressure sensing component 3, and a torque sensing component 4, the pressure on the test head 1 is transmitted to the pressure sensing component 3 through the transmission rod 2, and the torque on the test head 1 is transmitted to the torque sensing component 4 through the transmission rod 2, thereby achieving the purpose of real-time monitoring of pressure and torque, improving the pass rate of workpiece processing, and increasing production efficiency.

[0038] The intermediate plate 21 is provided with a protrusion 211, which is located on the same side of the intermediate plate 21 as the clamping block 23. The pressure sensing component 3 abuts against the protrusion 211. The setting of the protrusion 211 further improves the connection stability between the intermediate plate 21 and the pressure sensing component 3 and improves the reliability of the detected pressure value.

[0039] The housing 6 includes a base plate 61 and an outer shell 62 connected to the base plate 61. The control board 5 is connected to the base plate 61, the intermediate plate 21 is connected to the outer shell 62, and the pressure sensing component 3 is fixedly connected to the outer shell 62. The pressure sensing component 3, the torque sensing component 4, and the control board 5 are all located inside the outer shell 62. The outer shell 62 has a large and a small opening, with the large opening connected to the base plate 61, which serves to protect the pressure sensing component 3, the torque sensing component 4, and the control board 5.

[0040] The test head 1 includes a head 11 and a screw 12, the head 11 being connected to the screw 12, and also includes a bearing 13, which is installed inside the housing 62 and rotatably connected to the screw 12. The detachable structure of the head 11 and the screw 12 facilitates the replacement of different specifications of the head 11 to meet different usage requirements.

[0041] The test head 1 also includes a limiting ring 14 and a buffer 15. The limiting ring 14 is sleeved on the screw 12. The buffer 15 is located between the limiting ring 14 and the intermediate plate 21. The buffer 15 is sleeved on the rod 22. The buffer 15 is a spring. The two ends of the buffer 15 abut against the limiting ring 14 and the intermediate plate 21 respectively, so as to protect the rod 22 and avoid large external forces from colliding with the rod 22.

[0042] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
