Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, in particular to a brush disk testing machine. Background Art

[0002] In the current technical field of floor sweeping robots, as one of the core cleaning components, the durability and working efficiency of the brush disk directly affect the overall cleaning efficiency and user experience. However, when evaluating the lifespan of the floor sweeping robot brush disk, especially during wear testing, most traditional methods rely on manual simulation of the actual working environment for testing. This method not only has limited accuracy but also is time-consuming and laborious, making it difficult to meet the requirements of mass production and quality control.

[0003] To solve the problems of traditional manual testing, prior art has also designed automated testing means. For example, the ceramic grinding brush service life testing device for PCB disclosed in patent CN201821578191.X can achieve the purpose of automatic testing. However, it needs to drive the brush disk to lift and apply a certain pressure to simulate the wear during the cleaning process. Therefore, it is necessary to set up a structure to control the lifting of the brush disk and control the pressing force. As a result, this structure is relatively more complex, inconvenient to control, has a high assembly and maintenance cost, and is not flexible and convenient enough, restricting its wide application in actual production and detection links. Summary of the Invention

[0004] The utility model provides a brush disk testing machine for the problems of the prior art, with a simple structure and capable of realizing the automatic wear testing work of the brush disk.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: A brush disk testing machine includes a box body, a driving mechanism, and a supporting mechanism. A friction member is installed inside the box body. One end of the supporting mechanism is hinged to the box body, and the other end of the supporting mechanism is installed on the brush disk. The output end of the driving mechanism is drivingly connected to the brush disk, and the brush of the brush disk rotates on the surface of the friction member.

[0006] Preferably, the supporting mechanism includes a support arm and a connecting component. One end of the support arm is hinged to the box body, the other end of the support arm is installed on the connecting component, and the connecting component is installed on the brush disk.

[0007] Preferably, two groups of the supporting mechanism are provided, and a connecting rod is connected between the support arms of the two groups of the supporting mechanism.

[0008] Preferably, the connecting component includes a connecting piece, the connecting piece is detachably fixed on the brush disk, and the other end of the support arm is hinged to the connecting piece.

[0009] Preferably, the connecting member is provided with an arc-shaped hole. The connecting assembly further includes a locking member and a spring. The support arm is provided with a connecting hole. One end of the locking member is screwed with a nut, and a gasket is installed at the other end of the locking member. The locking member passes through the arc-shaped hole and the connecting hole. Both ends of the spring abut between the connecting member and the gasket. The nut is used to lock the locking member to the support arm.

[0010] Preferably, the box body is provided with a cleaning mechanism. When the brush disc rotates, the cleaning mechanism is used to clean the friction member.

[0011] Preferably, the cleaning mechanism includes a water inlet pipe and a sewage discharge assembly. The brush disc is provided with a water inlet groove. The water inlet pipe is assembled in the water inlet groove. The water inlet pipe is used to provide cleaning water for the brush disc and the friction member.

Specific embodiments

[0025] For the convenience of those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present utility model. The present utility model will be described in detail below with reference to the accompanying drawings.

[0026] A brush disk testing machine provided in this embodiment, as Figures 1 to 6 , includes a box body 1, a driving mechanism 2 and a support mechanism. A friction member 3 is installed in the box body 1. One end of the support mechanism is hinged to the box body 1, and the other end of the support mechanism is installed on the brush disk. The output end of the driving mechanism 2 is drivingly connected to the brush disk, and the brush of the brush disk rotates on the surface of the friction member 3. Among them, the friction member 3 can be selected as marble.

[0027] Specifically, the brush disk includes a brush body 18 and a brush cover 17, as Figure 6 shown. The assembly method between the brush body 18 and the brush cover 17 is the prior art. The driving mechanism 2 is installed on the brush cover 17. The driving mechanism 2 preferably uses a motor, and the fixing method is the prior art. For example, the motor is fixed on the brush cover 17 through common parts such as screws. The driving end of the motor passes through the brush cover 17 and is drivingly connected to the brush body 18, so as to drive the brush body 18 to rotate.

[0028] As Figure 4 and Figure 5 shown, the support mechanism of this embodiment includes a support arm 4 and a connection assembly. One end of the support arm 4 is hinged to the box body 1, and the other end of the support arm 4 is installed on the connection assembly, and the connection assembly is installed on the brush disk.

[0029] Specifically, a U-shaped mounting block 19 is fixed on the inner wall of the box body 1. One end of the support arm 4 is assembled on the U-shaped mounting block 19 through parts such as screws to achieve the purpose of hinging the support arm 4 to the box body 1. Then the other end of the support arm 4 is installed on the brush cover 17 through the connection assembly, as Figure 4As shown, the connecting component may optionally include a connecting piece 6, a locking piece 8, and a spring 9. The shape of the radial cross-section of the connecting piece 6 is preferably L-shaped. The brush cover 17 is provided with an assembling part 20. One side of the connecting piece 6 is locked to the assembling part 20 by common parts such as screws and bolts. The other side of the connecting piece 6 is also connected to the support arm 4 by parts such as screws and bolts. When the connecting piece 6 and the support arm 4 are assembled by a screw connection, the support arm 4 and the connecting piece 6 are also in a hinged state. In addition to the connection between the support arm 4 and the box body 1 being adjustable in angle, the angle between the support arm 4 and the brush disc can also be adjusted. In this structure, the staff can use the connection point between the support arm 4 and the box body 1 as a fulcrum to raise the brush disc to check the wear test condition of the brush disc. If only a small-angle elevation of the brush disc is required, the connection point between the connecting piece 6 and the support arm 4 can be used as a fulcrum to raise the brush disc at a small angle, making the operation of this embodiment more flexible.

[0030] Furthermore, the connecting component is also provided with a locking piece 8 and a spring 9. As Figure 4 shown, the connecting piece 6 is provided with an arc-shaped hole 7, and the support arm 4 is provided with a connection hole 10. One end of the locking piece 8 is screwed with a nut, and a gasket 11 is installed at the other end of the locking piece 8. The locking piece 8 passes through the arc-shaped hole 7 and the connection hole 10. The two ends of the spring 9 abut between the connecting piece 6 and the gasket 11. The nut is used to lock the locking piece 8 to the support arm 4. Specifically, the setting of the arc-shaped hole 7 can realize the hinge between the connecting piece 6 and the support arm 4, and at the same time, the range of the hinge is limited by the arc-shaped hole 7 to prevent the movement angle between the connecting piece 6 and the support arm 4 from being too large and affecting the accuracy of the wear test of the brush disc. The setting of the spring 9 can maintain the connection stability between the connecting piece 6 and the support arm 4 through the elastic force of the spring 9, and at the same time, can also maintain the movable performance of the connecting piece 6.

[0031] Furthermore, a connecting rod 5 is also connected between the two support arms 4 in this embodiment. The setting of the connecting rod 5 can maintain the consistency of the movement of the two support arms 4, ensure the uniformity of the force, and is also more convenient for the staff to use.

[0032] As Figure 2 and Figure 6 shown, this embodiment is also provided with a cleaning mechanism. The cleaning mechanism includes a water inlet pipe 12 and a sewage discharge component. The brush disc is provided with a water inlet groove 13, and the water inlet pipe 12 is assembled in the water inlet groove 13. The water inlet pipe 12 is used to provide cleaning water for the brush disc and the friction part 3. The box body 1 is provided with a sewage discharge port (not shown in the drawings). The sewage discharge component includes a sewage discharge pipe 15. The sewage discharge pipe 15 is communicated with the sewage discharge port and is used for draining water. A valve 16 is installed on the sewage discharge pipe 15, and the discharge of sewage is controlled by controlling the opening and closing of the valve 16.

[0033] Specifically, when the floor sweeper is in use, it is also necessary to provide a certain amount of clean water to the brush disk to clean the place being cleaned. Therefore, when testing the lifespan of the brush disk, in addition to controlling the rotation of the brush disk, clean water can be provided to the brush disk through the water inlet pipe 12, making the grinding test process more in line with actual applications and improving the accuracy of the test to a certain extent.

[0034] In the prior art, when setting up the lifting device, corresponding power resources will be consumed during the process of controlling the lifting of the brush disk, and a corresponding control system is required, resulting in a higher cost for the entire testing device. When actually testing the brush disk, the main work to be carried out is the rotation wear test. Therefore, in this embodiment, by setting up the support mechanism, it is more convenient for the staff to check the situation of the brush disk, and the weight of the brush disk itself can also be used for wear testing. Therefore, the structure of this embodiment is simpler, more flexible in operation, lower in cost, and higher in practicality compared to the prior art.

[0035] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in any form. Although the present invention is disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the technical solution scope of the present invention, when making some changes or modifications using the above-disclosed technical content as equivalent change equivalent embodiments, but as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments according to the technical means of the present invention shall fall within the scope of the technical solution of the present invention.
