Description

Technical Field

[0001] This utility model belongs to the field of equipment testing technology and relates to a roller brush test frame with a self-locking switch. Background Technology

[0002] To improve waste collection efficiency, a rotating brush is typically installed at the front of a water surface cleaning robot. During waste collection, the rotating brush primarily pushes the waste into a collection bin. For example, Chinese utility model patent [Patent No. 202322785915.5] discloses a rotating brush for a water surface cleaning robot. This robot has a rotating brush mounted on its shell, with both ends connected to the shell. Inside the shell is a collection bin with a baffle on one side and an opening extending to the baffle at the top. The rotating brush is positioned above the baffle and includes several blades, each with a hook at one end facing the water-entry side. The brush is hinged to the robot shell via a snap-fit ​​connection to a mounting hole. A motor and a transmission gear are fixedly connected inside the snap-fit ​​hole, meshing with each other. The transmission gear is fixedly connected to the snap-fit ​​connection. Disassembling this brush is inconvenient; the motor must be disassembled first, and then the brush removed from the robot shell. To test the stability of the roller brush mechanism during rotation, it is only necessary to install the roller brush mechanism onto the test equipment. Therefore, a roller brush mechanism that can be installed without disassembling the motor needs to be designed, making the testing of the roller brush mechanism more efficient. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a roller brush test frame with a self-locking switch, which allows for fast installation and disassembly, thereby improving testing efficiency.

[0004] The purpose of this utility model can be achieved through the following technical solution: A roller brush test frame with a self-locking switch includes a concave mounting base, a drive assembly, roller brush plates, a spindle, and a positioning sleeve. The concave mounting base has a left vertical plate and a right vertical plate. The drive assembly is fixed on the outside of the left vertical plate. The right vertical plate has a mounting cylinder. The positioning sleeve is embedded in the mounting cylinder and fixed to the mounting cylinder. Several roller brush plates are sleeved on the spindle and rotate synchronously with the spindle. One end of the spindle is poweredly connected to the drive assembly. The other end of the spindle is rotatably connected to a bearing. The bearing is embedded in the inner end of the positioning sleeve. The outer end of the positioning sleeve is connected to an end cap that can automatically lock onto the positioning sleeve.

[0005] Furthermore, the outer end of the positioning sleeve is fitted with an elastic claw, and the inner center of the end cap has a protruding head that can be held by the elastic claw. The outer end of the positioning sleeve also has several circumferentially distributed square tubes, and the edges of the square tubes are connected to elastic rods that extend out of the square tubes. The outer ends of the elastic rods abut against the inner surface of the end cap.

[0006] Furthermore, the outer end of the positioning sleeve has a horizontally extended flange with a connecting hole on it, and the mounting sleeve has several threaded holes. After the connecting hole and the threaded hole are aligned, they are fastened by inserting bolts.

[0007] Furthermore, the cross-section of the mandrel is a regular hexagon, and protective covers are fitted at both ends of the mandrel. The protective covers have slots that engage with the roller brush plate.

[0008] Furthermore, the drive assembly includes a housing, a motor, a drive shaft, and a screw. The motor is fixed inside the housing, the drive shaft is rotatably connected to the housing, a worm gear is fixed on the drive shaft, the worm meshes with the worm gear, and a hexagonal hole is opened on the drive shaft for inserting a mandrel.

[0009] Furthermore, the roller brush plate has three parts, each with a central hole through which the mandrel passes. The three roller brush plates are arranged in a row and fitted onto the mandrel, rotating synchronously with the mandrel. After the mandrel is removed, the roller brush plates separate from each other, allowing for cleaning or replacement of the roller brush plates.

[0010] Furthermore, the bottom of the concave mounting base has reinforcing ribs. These ribs increase the strength of the concave mounting base.

[0011] During testing, each component must be installed first. First, each roller brush plate is fitted onto the mandrel. One end of the mandrel engages with the drive shaft of the drive assembly, while the other end is rotatably connected to the positioning sleeve via a bearing. The positioning sleeve is inserted into the mounting cylinder, and the bolts are tightened to secure it. Finally, the protrusion engages with the elastic claw, completing the end cap installation. Start the motor to rotate the roller brush plates and observe their rotational stability, such as coaxiality, any abnormal noises or scraping, and whether the end cap will fall off due to vibration. After testing, disassembly is required. First, press the end cap inwards. The inner side of the end cap presses against the elastic rod, causing it to bend inwards. Upon releasing, the elastic rod's rebound force pushes the end cap outwards, causing the protrusion to disengage from the elastic claw. At this point, the end cap disengages from the positioning sleeve. Unscrew the bolts, and the positioning sleeve can be pulled out from the mounting cylinder along with the mandrel and roller brush plates, completing the disassembly.

[0012] Compared with existing technologies, this roller brush test fixture with a self-locking switch has the following advantages:

[0013] 1. The spindle and drive shaft are connected by a plug-in method. The positioning sleeve and spindle can be pulled out from the mounting sleeve on the other side of the drive assembly, and the roller brush plate can be removed from the concave mounting bracket without disassembling the motor of the drive assembly. The installation and disassembly are very quick and convenient, improving the testing efficiency.

[0014] 2. The end cap is self-locking. The protrusion can be inserted into the elastic claw to complete the installation. Pressing the end cap inward again will push it out by the rebound force of the elastic rod to complete the disassembly. Attached Figure Description

[0023] like Figure 1-3 As shown, this roller brush test frame with a self-locking switch includes a concave mounting base 1, a drive assembly 2, roller brush plates 3, a spindle 4, and a positioning sleeve 19. The concave mounting base 1 has a left vertical plate 11 and a right vertical plate 12. The drive assembly 2 is fixed to the outside of the left vertical plate 11. The right vertical plate 12 has a mounting cylinder 13. The positioning sleeve 19 is embedded in the mounting cylinder 13 and fixed to the mounting cylinder 13. Several roller brush plates 3 are sleeved on the spindle 4 and rotate synchronously with the spindle 4. One end of the spindle 4 is poweredly connected to the drive assembly 2, and the other end of the spindle 4 is rotatably connected to a bearing 6. The bearing 6 is embedded in the inner end of the positioning sleeve 19. The outer end of the positioning sleeve 19 is connected to an end cap 7 that can automatically lock onto the positioning sleeve 19.

[0024] like Figure 3 , Figure 6As shown, the positioning sleeve 19 has an elastic claw 51 embedded in the center of its outer end, and the end cap 7 has a protruding head 71 that can be held by the elastic claw 51 in the center of its inner side. The positioning sleeve 19 also has several circumferentially distributed square tubes 52 on its outer end. The edges of the square tubes 52 are connected to elastic rods 53 that extend out of the square tubes 52, and the outer ends of the elastic rods 53 abut against the inner side of the end cap 7.

[0025] The outer end of the positioning sleeve 19 has a horizontally extended flange 54 with a connecting hole 55. The mounting sleeve 13 has several threaded holes. After the connecting hole 55 is aligned with the threaded holes, it is tightened by inserting bolts. The bottom of the concave mounting base 1 has a reinforcing rib 14, which improves the strength of the concave mounting base 1.

[0026] like Figure 4 As shown, the cross-section of the mandrel 4 is a regular hexagon, and protective covers 8 are fitted at both ends of the mandrel 4. The protective covers 8 have slots for engaging with the roller brush plates 3. There are three roller brush plates 3, each with a central hole through which the mandrel 4 passes. The three roller brush plates 3 are arranged in a line on the mandrel 4, with the ends of adjacent roller brush plates 3 abutting together. The three roller brush plates 3 rotate synchronously with the mandrel 4. After the mandrel 4 is removed, the roller brush plates 3 separate, allowing for cleaning or replacement.

[0027] like Figure 5 As shown, the drive assembly 2 includes a housing 21, a motor 22, a drive shaft 23, and a screw 24. The motor 22 is fixed inside the housing 21, and the drive shaft 23 is rotatably connected to the housing 21. A worm gear 25 is fixed on the drive shaft 23, and the worm meshes with the worm gear 25.

When disassembly is required after testing, first press the end cap 7 inward. The inner side of the end cap 7 will squeeze the elastic rod 53, causing the elastic rod 53 to bend inward under force. After releasing, due to the rebound force of the elastic rod 53, the end cap 7 will be pushed outward, causing the protrusion 71 to disengage from the elastic claw 51. At this time, the end cap 7 will disengage from the positioning sleeve 19. Unscrew the bolts, and the positioning sleeve 19 can be pulled out from the mounting cylinder 13. The mandrel 4 and the roller brush plate 3 will also be pulled out together, completing the disassembly.
