[0004] However, the existing detection device can only detect small motors, but cannot detect large motors or specific parts of motors, and its overall practicality and adaptability are poor. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0034] See also Figure 1 and 2 As shown, the present invention is a motor voiceprint detection device based on bone conduction, including an outer shell 1 and a voiceprint collection component 2. The upper side of the outer shell 1 has an upper cover 101, and the outer shell 1 and the upper cover 101 can be connected by screws or by snap-on connection. Four fixing columns 102 are fixedly connected to the lower surface of the outer shell 1, and a magnet 103 is fixedly connected to the lower end of the fixing column 102. For example, a blind hole is opened at the lower end of the fixing column 102, and the magnet 103 is embedded in the blind hole by gluing or the like.

[0035] like Figures 4 to 6 As shown, the voiceprint collection component 2 is located inside the outer shell 1, and the voiceprint collection component 2 includes a collection box body 201, in which a bone conduction sensor 3 is installed, and the collection box body 201 has an upper end cover, and the upper end cover is provided with a threading hole for the cable to pass through, and the bone conduction sensor 3 is installed on the inner bottom wall of the collection box body 201, and the collection box body 201 is closed by the upper end cover, so that the bone conduction sensor 3 is located in an internal closed environment.

[0036] like Figure 7 and 8 As shown, four compression springs 202 are connected between the collection box body 201 and the upper cover 101, and a conduction rod 203 that penetrates through the bottom wall of the outer shell 1 is fixedly connected to the lower surface of the collection box body 201. The collection box body 201 and the conduction rod 203 can be an integrated structure, or connected by threaded connection or welding.

[0037] The magnet 103 is adsorbed and fixed, and the compression spring 202 is used to push the collection box body, so that the conduction rod can be flexibly extended and retracted, so that it can better adapt to the external shape of the motor, and effectively improve the overall practicality and adaptability.

[0038] Specifically, when it is necessary to detect a specific part of the motor, such as the bearing installation position, the magnet 103 is adsorbed and fixed to the surface of the motor, so that the conduction rod 203 corresponds to the bearing installation position of the motor, and the collection box 201 is pushed by the compression spring 202, so that the conduction rod 203 is tightly attached to the surface of the motor. When the motor starts, the bone conduction sensor 3 is used to obtain vibration information, and then the voiceprint comparison is used to detect whether the rotation of the motor is abnormal.

[0039] As a preferred embodiment, the lower end surface of the conduction rod 203 is a curved structure to avoid scratches on the motor surface, etc. The outer wall of the collection box body 201 is covered with sound insulation material, and the inner wall of the outer shell 1 is covered with sound insulation material, thereby reducing the external sound vibration transmitted to the inside of the collection box body 201, which is conducive to ensuring the accuracy of the detection.

[0040] At the same time, the upper cover 101 is rotatably connected with a screw rod 104 and movably interspersed with four connecting columns 105. A connecting plate 106 is fixedly connected to the upper ends of the four connecting columns 105, and a stopper 107 is fixedly connected to the lower ends of the connecting columns 105 and extends to the inside of the outer shell 1. The connecting plate 106 is provided with a threaded hole that matches the screw rod 102, and a knob is connected to the upper end of the screw rod 104, so that the connecting plate 106 can be driven to move up and down by rotating the screw rod 104.

[0041] Four connecting ears 204 are fixedly connected to the outer wall of the collection box body 201, and the connecting columns 105 are movably interlaced with the connecting ears 204 one by one, and the compression springs 202 are correspondingly sleeved on the outside of the connecting columns 105, which is beneficial to improve the stability of the compression springs 202.

[0042] By rotating the screw rod 104, the connecting column 105 is driven upward through the connecting plate 106. When the stopper 107 abuts against the lower limit surface of the connecting ear 204, the collection box body 201 is driven upward through the stopper 107, so that the lower end surface of the conduction rod 203 is higher than the lower end surface of the fixed column 102, thereby avoiding the conduction rod 203 from being easily hit when the magnet 103 adsorbs the motor.

[0043] In addition, if Figure 3 and 5 As shown, a protective sleeve 108 is fixedly connected to the lower surface of the outer shell 1, and the outer shell 1 and the protective sleeve 108 can be an integrated structure or fixed by threaded connection or welding. The protective sleeve 108 is sleeved on the outside of the conductive rod 203, and is used to drive the collection box 201 to move upward through the connecting column 105, so that the lower end of the conductive rod 203 is retracted into the protective sleeve 108, thereby protecting the conductive rod 203, thereby further protecting the conductive rod 203.

[0044] like Figure 5 and 6As shown, during detection, after the magnet 103 is adsorbed and fixed on the surface of the motor, the screw 104 is rotated to make the connecting plate 106 drive the connecting column 105 to move downward, and the compression spring 202 pushes the collection box body 201 to move downward. When the conduction rod 203 is in close contact with the surface of the motor, the screw 104 is continuously rotated to make the connecting column 105 continue to move downward, so that the conduction rod 203 is completely pressed against the surface of the motor by the elastic force of the compression spring 202, thereby ensuring the fit between the conduction rod 203 and the surface of the motor.

[0045] As another preferred embodiment, the fixed column 102 is provided with a top sleeve 401, four top sleeves 401 are fixedly connected to a hollow plate 4, and the hollow plate 4 is connected to a pressure rod 402. The number of the pressure rods 402 is two or four, and they are symmetrically arranged relative to the outer shell 1, taking two in the figure as an example.

[0046] The top cover 401 and the hollow plate 4 are fixed by welding, or the top cover 401 and the hollow plate 4 are made of nylon and connected by gluing or are an integrated structure. The outer wall of the outer shell 1 is welded or connected by screws with a gripping rod 109 located below the pressure rod 402.

[0047] After the detection is completed, the inspector holds the pressure rod 402 and the grip rod 109, and presses down the pressure rod 402 to move the top cover 401 downward, and uses the top cover 401 to push the surface of the motor to move the outer shell 1 upward as a whole, thereby separating the magnet 103 from the motor, making it easier to remove the motor voiceprint detection device, thereby improving the overall convenience of use.
