Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and specifically to a wear resistance detection device for the processing of cleaning heads. Background Technique

[0002] In the fields of sanitation equipment, industrial cleaning machinery, etc., the rotary cleaning brush is a core component, and its wear resistance directly affects the cleaning efficiency and service life. At present, during the processing of cleaning brushes, the wear resistance detection mainly faces the following technical bottlenecks.

[0003] Traditional detection heads can usually only perform one-way or partial detection. For problems such as contact stress concentration caused by assembly deviations of the brush, such as the inclination of the helical surface and inconsistent brush heights, there is a lack of real-time temperature rise monitoring means and potential defects cannot be accurately located. Existing detection devices generally ignore the load impact on the cleaning brush when the ground is uneven and can only perform wear resistance tests under the working conditions of a single plane, unable to simulate the contact pressure fluctuations caused by ground unevenness during actual cleaning, resulting in a disconnection between the detection results and the engineering application scenarios and making it difficult to effectively evaluate the wear resistance of the cleaning brush under complex working conditions. In addition, traditional detection devices do not integrate a coating protection function. Generally, the cleaning brush needs to be transferred to an independent device for protective coating spraying, with a cumbersome process and difficult control of coating uniformity. Therefore, we propose a wear resistance detection device for the processing of cleaning heads. Summary of the Invention

[0023] Specifically, the first bracket 21 is fixedly installed with the first motor 22 to provide rotation support for the first rotating shaft 24. The first motor 22 serves as a power source to drive the first rotating shaft 24 to rotate, thereby driving the cleaning head body 5 to rotate and the detection component to be linked. The first rotating shaft 24 transmits the power of the first motor 22, is coaxially connected to the second bracket 25 to fix the cleaning head body 5, and drives the detection head transmission chain through the first bevel gear 23 on the outside. The second bracket 25 is symmetrically clamped and fixed to the rotating shaft of the cleaning head body 5 through two groups of first electric telescopic rods 26 and clamping plates 27 to ensure that its axis is coaxial with the first rotating shaft 24. The first electric telescopic rod 26 drives the clamping plate 27 to adjust the spacing through telescopic movement to adapt to the rotating shafts of cleaning heads of different specifications, and completes rapid clamping and positioning. The cleaning head body 5 is a component to be tested. The outer spiral bevel assembly strip is used to install the brush. Its spiral structure cooperates with the slide groove of the detection plate 85 to realize self-rotation detection.

[0024] In this embodiment, the outer side of the first bevel gear 23 is meshedly connected with the second bevel gear 28, the lower end of the second bevel gear 28 is rotatably connected to the first bracket 21 through a rotating shaft, the outer side of the second bevel gear 28 is meshedly connected with the third bevel gear 29, the inner side of the third bevel gear 29 is rotatably connected to the first rotating shaft 24, and one end of the third bevel gear 29 is fixedly connected to the first spur gear 210 through a sleeve.

[0025] Specifically, the first bevel gear 23 is coaxially fixed with the first rotating shaft 24, and the rotational power is transmitted to the second bevel gear 28 in the vertical direction to realize the conversion of the transmission direction. The second bevel gear 28 rotates around the rotating shaft at the lower end of the first bracket 21, meshes with the first bevel gear 23 and drives the third bevel gear 29, forming a two-stage bevel gear transmission. The third bevel gear 29 is loosely sleeved on the outside of the first rotating shaft 24 and is fixed to the first spur gear 210 through a sleeve, and finally drives the laser flatness detection head 3 to rotate in the opposite direction to realize the opposite scanning with the cleaning head body 5.

[0026] In this embodiment, the outer side of the first spur gear 210 is rotatably connected to a synchronous belt 211, and the inner side of the synchronous belt 211 is rotatably connected to a second spur gear 212. One end of the second spur gear 212 is fixedly connected to a second rotating shaft 213, and the other end of the synchronous belt 211 is rotatably connected to the base 1 via a rotating shaft.

[0027] Specifically, the first spur gear 210 is driven by a bevel gear set and is connected to a synchronous belt 211 on the outside to transmit power to the second spur gear 212, while fixing the laser flatness detection head 3 and the infrared temperature detection head 4. The synchronous belt 211 and the second spur gear 212 constitute a belt transmission system, which transmits the rotational power of the first spur gear 210 to the second rotating shaft 213, driving the friction mechanism 6 to rotate.

[0028] In this embodiment, the friction mechanism 6 includes two groups of parallel strip drive plates 61, one side of one group of the strip drive plates 61 is fixedly connected to the second rotating shaft 213, and the sides of the two groups of strip drive plates 61 that are close to each other are commonly fixedly connected to the third rotating shaft 69, and the other end of the third rotating shaft 69 is rotatably connected to the base 1. The strip drive plates 61 are provided with multiple groups of fulcrums, and the inner side of the strip drive plates 61 is slidably connected to multiple groups of sliding rods 62, and the ends of the multiple groups of sliding rods 62 that are far away from each other are fixedly connected to the arc support plate 612.

[0029] Specifically, two groups of strip drive plates 61 are arranged in parallel, one group is fixed to the second rotating shaft 213, rotates with it and is rotatably connected to the base 1 through the third rotating shaft 69, forming a rotating frame of the friction mechanism 6, and the sliding rod 62 drives the arc support plate 612 to slide along the inner side of the strip drive plate 61, and cooperates with the limiting groove 65 of the third spur gear 64 through the end rotating shaft 63. When moving radially, the arc support plate 612 is stretched open to adjust the inner diameter of the friction cylinder 7. The friction cylinder 7 is made of rubber and wraps the arc support plate 612, contacts with the brush of the cleaning head and provides friction resistance. The fitting area is changed by adjusting the inner diameter to control the degree of friction.

[0030] In this embodiment, one side of the strip driving plate 61 is rotatably connected to a third spur gear 64 through a sleeve, and multiple groups of limit grooves 65 are provided on the outer side of the third spur gear 64. The inner side of the limit groove 65 is slidably connected to the rotating shaft 63, and one end of the rotating shaft 63 is fixedly connected to the sliding rod 62.

[0031] Specifically, the third spur gear 64 is rotatably connected to the strip-shaped driving plate 61 through a sleeve, and the outer limiting groove 65 is slidably matched with the rotating shaft 63 of the slide bar 62, driving the slide bar 62 to move radially when rotating.

[0032] In this embodiment, a second motor 68 is installed on one side of one of the two sets of strip-shaped drive plates 61. A threaded rod 67 is rotatably connected to the inner sides of the two sets of strip-shaped drive plates 61. The output shaft of the second motor 68 is fixedly connected to the threaded rod 67. Two symmetrically arranged fourth spur gears 66 are fixedly connected to the outer side of the threaded rod 67, and the outer sides of the fourth spur gears 66 are meshed with third spur gears 64.

[0033] Specifically, the second motor 68 drives the threaded rod 67 to rotate. By meshing the fourth spur gears 66 at both ends with the third spur gears 64, the synchronous radial adjustment of the two side slide bars 62 is realized, ensuring symmetric change in the inner diameter of the friction cylinder 7. The fourth spur gears 66 are fixed on the outer side of the threaded rod 67 and meshed with the third spur gears 64, converting the rotational motion of the threaded rod 67 into the rotational motion of the gears, and then driving the slide bars 62 to move.

[0034] In this embodiment, a mounting block 610 is threadedly connected to the outer side of the threaded rod 67. The inner side of the mounting block 610 is slidably connected to a third rotating shaft 69. A second electric telescopic rod 611 is installed at the upper end of the mounting block 610, and the output shaft of the second electric telescopic rod 611 is fixedly connected to a rigid support plate.

[0035] Specifically, the mounting block 610 is threadedly connected to the threaded rod 67 and translates axially along the third rotating shaft 69, driving the second electric telescopic rod 611 to move to different circumferential positions. When the second electric telescopic rod 611 extends, the rigid support plate jacks up the inner wall of the friction cylinder 7 to form bumps. The friction cylinder 7 is made of hard rubber material, and the friction cylinder 7 is polyurethane rubber. Polyurethane rubber belongs to a relatively hard rubber material and can accurately bulge and deform under high load. By adjusting the telescopic length and the position of the mounting block 610, the contact pressure fluctuation caused by the uneven ground is simulated.

[0036] In this embodiment, the maintenance mechanism 8 includes a mounting plate 81 fixedly connected to the base 1. One side of the mounting plate 81 is rotatably connected to the cleaning head main body 5. Two sets of third electric telescopic rods 82 are installed on one side of the mounting plate 81. The output shafts of the third electric telescopic rods 82 penetrate through the mounting plate 81. The output shafts of the two sets of third electric telescopic rods 82 are jointly fixedly connected to an annular plate 83. Multiple L-shaped fixing rods 84 are fixedly connected to the other side of the annular plate 83. A ball is installed at the other end of the L-shaped fixing rod 84. A detection plate 85 is slidably connected to the outer side of the L-shaped fixing rod 84. Multiple sliding grooves are formed in the inner wall of the detection plate 85, and CCD cameras are installed inside the sliding grooves.

[0037] Specifically, the mounting plate 81 is fixed on the base 1 and is rotatably connected to the main body 5 of the cleaning head at one side, providing a mounting reference for the maintenance mechanism 8. The third electric telescopic rod 82 drives the annular plate 83 to move through expansion and contraction, driving the L-shaped fixing rod 84 and the detection plate 85 to approach or move away from the cleaning head, triggering the detection and cleaning actions. The L-shaped fixing rod 84 connects the annular plate 83 and the detection plate 85. The ball reduces the frictional resistance during the translation of the detection plate 85 and cooperates with the spiral bevel assembly strip to make the detection plate 85 rotate self - sufficiently, realizing 360° scanning. The inner wall chute of the detection plate 85 fits with the spiral bevel assembly strip of the cleaning head. When rotating self - sufficiently, the worn surface of the brush is photographed by the CCD camera and compared with the initial data to judge the wear resistance.

[0038] In this embodiment, an air pump 87 is installed at the upper end of the detection plate 85. An arc - shaped scraper 86 is fixedly connected to one side of the detection plate 85. An electrostatic adsorption module is installed on the inner wall of the arc - shaped scraper 86. An air extraction pipe 88 is installed inside the arc - shaped scraper 86. Filter holes are formed on the outer side of the air extraction pipe 88. The input port of the air pump 87 is fixedly connected to the air extraction pipe 88 through a pipeline. The output port of the air pump 87 is fixedly connected to a coating tank 89. The other end of the coating tank 89 is installed with an electromagnetic spray head 810. An electromagnetic pressure relief valve 811 is installed on the outer side of the coating tank 89. A pressing plate 812 is slidably connected to the inner side of the coating tank 89. A limiting block is fixedly connected to the outer side of the pressing plate 812. A spring 813 is arranged inside the coating tank 89. One end of the spring 813 is fixedly connected to the pressing plate 812, and the other end of the spring 813 is fixedly connected to the coating tank 89.

[0039] Specifically, the arc - shaped scraper 86 fits the surface of the brush. The electrostatic adsorption module captures the particles generated by friction. The filter holes of the air extraction pipe 88 collect impurities to ensure the cleanliness of the brush before detection. The input end of the air pump 87 sucks dust through the air extraction pipe 88, and the output end inflates the coating tank 89, pushing the pressing plate 812 to compress the spring 813, providing power for pressurizing the coating liquid. The coating tank 89 stores the coating liquid. Under the drive of air pressure, it is sprayed around the surface of the brush through the electromagnetic spray head 810 to form a protective coating. The opening degree of the electromagnetic spray head 810 can be adjusted to adapt to different spraying requirements. The pressing plate 812 compresses the spring 813 under the action of air pressure, and the limiting block limits the maximum stroke to prevent excessive pressure. The elastic reset of the spring 813 cooperates with the electromagnetic pressure relief valve 811 to realize the dynamic balance of the pressure in the coating tank 89 and ensure the spraying stability.

[0040] Working principle: when in use, the two groups of first electric telescopic rods 26 on the inner side of the second bracket 25 of the detection mechanism 2 drive the clamping plate 27 to symmetrically clamp and fix the rotating shaft of the cleaning head main body 5 to complete the installation. At this time, the spiral bevel assembly strip on the outer side of the cleaning head main body 5 is positioned with the clamping plate 27, and its axis is coaxial with the first rotating shaft 24. The first motor 22 is started, and its output shaft drives the first rotating shaft 24 to rotate. The first rotating shaft 24 directly drives the second bracket 25 to rotate, so that the second bracket 25 drives the cleaning head main body 5 to rotate around its own axis. The first bevel gear 23 on the outside of the first rotating shaft 24 meshes and drives the second bevel gear 28, the second bevel gear 28 drives the third bevel gear 29 to rotate, and then the third bevel gear 29 drives the first spur gear 210 to rotate in the opposite direction, the first spur gear 210 drives the laser flatness detection head 3 at the end to rotate in the opposite direction around the axis of the cleaning head body 5, and dynamically scans and detects the flatness of the spiral surface of the outer brush, and the infrared temperature detection head 4 synchronously monitors the temperature change in the friction area of the brush, and locates the assembly deviation or contact stress concentration point through abnormal temperature rise.

[0041] The first spur gear 210 drives the second spur gear 212 through the synchronous belt 211, driving the second rotating shaft 213 to rotate, and then driving the strip driving plate 61 of the friction mechanism 6 to rotate around the third rotating shaft 69, starting the second motor 68, and its output shaft drives the threaded rod 67 to rotate, and drives the third spur gear 64 through the meshing of the fourth spur gear 66 symmetrical at both ends, and the limiting groove 65 on the outer side of the third spur gear 64 slides with the rotating shaft 63 at the end of the slide rod 62. When the gear rotates, the rotating shaft 63 moves radially along the limiting groove 65, pushing the slide rod 62 to slide to the outside of the strip driving plate 61, driving the arc-shaped support plate 612 to open, realizing the dynamic adjustment of the inner diameter of the rubber friction cylinder 7, changing the contact area with the cleaning head brush, and flexibly controlling the friction degree of the cleaning head body 5. The threaded rod 67 drives the mounting block 610 to translate axially along the third rotating shaft 69, driving the second electric telescopic rod 611 to move synchronously, and the rigid support sheet at the output shaft end thereof lifts up the inner wall of the friction cylinder 7, generating height-adjustable convex points at different circumferential positions, simulating the contact pressure fluctuation caused by the unevenness of the ground during cleaning, and testing the wear resistance of the brush under variable load; After friction detection, the friction mechanism 6 is reset to stagger the friction cylinder 7 from the main body 5 of the cleaning head. The third electric telescopic rod 82 drives the annular plate 83, and drives the detection plate 85 to axially move through the L-shaped fixing rod 84. The inner wall sliding groove of the detection plate 85 is precisely fitted with the spiral bevel assembly strip on the outside of the main body 5 of the cleaning head. When the detection plate 85 axially translates, it generates a self-rotation motion due to the spiral structure, and the friction is reduced by the ball at the end of the L-shaped rod to achieve 360° dead-angle-free scanning. The electrostatic adsorption module on the inner wall of the arc-shaped scraper 86 adsorbs the particles generated by friction. At the same time, the air pump 87 collects impurities through the filter holes of the air extraction pipe 88 to ensure the cleanliness of the brush surface. The CCD camera in the sliding groove of the detection plate 85 takes real-time pictures of the worn area and compares it with the initial three-dimensional model to determine whether the wear resistance meets the standard. The air flow output by the air pump 87 enters the coating tank 89, pushes the pressing plate 812 to compress the spring 813, pressurizes the coating liquid in the tank. The electromagnetic spray head 810 adjusts the opening according to the detection result and evenly sprays the coating liquid on the brush surface.
