Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, specifically a gear cleaning device. Background Technology

[0002] Gears are meshing toothed mechanical parts widely used in mechanical equipment and are important transmission components in mechanical transmission. During the manufacturing process, gears inevitably accumulate impurities such as oil, cutting chips, and dust on their surfaces, especially in the tooth flanks between the teeth, where impurities are more likely to adhere. If directly assembled and used, these impurities can easily cause unstable meshing, resulting in poor precision or deformation. Therefore, it is necessary to clean the tooth flanks of the gears.

[0003] In existing technologies, gear cleaning is mostly done manually by workers using tools such as brushes or spray guns. This not only requires a large amount of manpower, but also inevitably results in some minor areas such as gear teeth not being cleaned completely, leading to low gear cleaning efficiency.

[0007] As a further preferred embodiment of this technical solution, the two ends of the two sets of bidirectional lead screws pass through the two sets of face brushes respectively and are threadedly connected to the two sets of face brushes respectively. Synchronous pulleys are sleeved on both sets of bidirectional lead screws. A synchronous belt is provided in the fixed frame. The synchronous belt is connected to the two sets of synchronous pulleys respectively.

[0008] As a further preferred embodiment of this technical solution, the fixed frame is slidably connected to the fixed rod via a slider, the two ends of the spring are respectively fixedly connected to the fixed frame and the movable frame, and the cam is fitted to the slider.

[0009] As a further preferred embodiment of this technical solution, a second cylinder is fixedly installed inside the mounting rod, the adjusting rod is connected to the output end of the piston rod of the second cylinder, the left end of the first adjusting frame is rotatably connected to the mounting rod via a rotating shaft, the right end of the first adjusting frame is slidably connected to the abutment rod, and both ends of the second adjusting frame are rotatably connected to the adjusting rod and the abutment rod respectively via rotating shafts.

[0010] As a further preferred embodiment of this technical solution, two sets of symmetrically distributed clamping rings are slidably installed inside the abutment rod, and a bidirectional screw is rotatably installed inside the abutment rod.

[0012] This utility model provides a gear cleaning device, which has the following beneficial effects:

[0013] (1) This utility model achieves synchronous cleaning of gear teeth and both sides by setting a fixed frame, side brush and two sets of face brushes, avoiding the situation that manual cleaning is not thorough. The positions of the two sets of face brushes, the moving frame and the fixed frame can be adjusted according to the thickness and diameter of the gear being cleaned, so that the cleaning device can effectively clean all parts of the gear without being limited to a specific gear size, effectively expanding the scope of application of the cleaning device.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 Figure 4As shown, in this embodiment, a gear cleaning device includes a mounting frame 1, a water tank 2 mounted on the mounting frame 1, a mounting base 3 above the water tank 2, a first cylinder 4 mounted on the mounting frame 1, the mounting base 3 connected to the output end of the piston rod of the first cylinder 4, a movable frame 5 slidably mounted inside the mounting base 3, a first threaded rod 6 rotatably mounted inside the mounting base 3, a fixed frame 7 slidably mounted on the movable frame 5, a side brush 8 fixedly mounted on the fixed frame 7, two sets of symmetrically distributed surface brushes 9 slidably mounted on the fixed frame 7, a bidirectional lead screw 10 rotatably mounted inside the fixed frame 7, a fixed rod 13 fixedly mounted inside the movable frame 5, a spring 15 sleeved on the fixed rod 13, and a cam 16 rotatably mounted inside the movable frame 5. A mounting rod 17 is rotatably mounted on the mounting base 3. An adjusting rod 18 is slidably mounted inside the mounting rod 17. Four sets of symmetrically distributed abutments 20 are provided around the adjusting rod 18 and the mounting rod 17. Two sets of cross-distributed first adjusting frames 21 and second adjusting frames 22 are provided between the abutments 20, the mounting rod 17, and the adjusting rod 18. According to the actual gear model that needs to be cleaned, the motor in the mounting base 3 is started to drive the first threaded rod 6 to rotate. Under the limiting action of the mounting base 3, the moving frame 5 slides within the mounting base 3 until the side plate is in contact with the gear tooth surface. The motor in the fixed frame 7 is started to drive the bidirectional lead screw 10 to rotate. Under the cooperation of the synchronous belt 12 and the synchronous pulley 11 in the fixed frame 7, the two sets of bidirectional lead screws... The rod 10 rotates synchronously, and under the limiting action of the fixed frame 7, the distance between the two sets of face brushes 9 is adjusted, so that the two sets of face brushes 9 are in contact with the two sides of the gear. The gear, side brushes 8, and face brushes 9 under the mounting base 3 are all placed in the water tank 2, which contains cleaning solution. The gear rotates at a constant speed under the drive of the mounting rod 17. The motor in the moving frame 5 drives the cam 16 to rotate. The cam 16 intermittently pushes the slider 14, and under the action of the spring 15, the slider 14 drives the fixed frame 7 to reciprocate on the moving frame 5. During the movement, the two sets of face brushes 9 and side brushes 8 synchronously clean the upper and lower surfaces and the sides of the teeth of the gear during the rotation, ensuring cleaning effect and improving cleaning efficiency. Impurities adhering to the gears on the face brush 9 and side brush 8 fall into the cleaning solution during the left and right vibration. The two ends of the first threaded rod 6 pass through the movable frame 5 and are threadedly connected to the movable frame 5. The two sets of face brushes 9 are located on both sides of the side brush 8. The two ends of the two sets of bidirectional screws 10 pass through the two sets of face brushes 9 and are threadedly connected to the two sets of face brushes 9. Synchronous pulleys 11 are sleeved on the two sets of bidirectional screws 10. A synchronous belt 12 is provided inside the fixed frame 7. The synchronous belt 12 is connected to the two sets of synchronous pulleys 11 for transmission. The fixed frame 7 is slidably sleeved with the fixed rod 13 through the slider 14. The two ends of the spring 15 are fixedly connected to the fixed frame 7 and the movable frame 5 respectively. The cam 16 is fitted with the slider 14.

[0024] like Figure 5 and Figure 6As shown, a second cylinder 19 is fixedly installed inside the mounting rod 17. The adjusting rod 18 is connected to the output end of the piston rod of the second cylinder 19. The left end of the first adjusting bracket 21 is rotatably connected to the mounting rod 17 via a rotating shaft, and the right end of the first adjusting bracket 21 is slidably connected to the abutment rod 20. The two ends of the second adjusting bracket 22 are rotatably connected to the adjusting rod 18 and the abutment rod 20 respectively via rotating shafts. During the sliding process of the second cylinder 19 in the mounting rod 17 driving the adjusting rod 18, the angle between the abutment rod 20 and the mounting rod 17 and the adjusting rod 18 supported by the first adjusting bracket 21 and the second adjusting bracket 22 changes, thereby changing the distance between the four sets of abutment rods 20 and the mounting rod 17, so that the four sets of abutment rods 20 are all in contact with the inner ring surface of the gear to be fixed. Two sets of symmetrically distributed clamping rings 23 are slidably installed inside the abutment rod 20, and a bidirectional screw 24 is rotatably installed inside the abutment rod 20. Two sets of clamping rings 23 pass through both ends of the bidirectional screw 24 and are threadedly connected to the two sets of clamping rings 23 respectively. The motor in the push rod 20 drives the bidirectional screw 24 to rotate, adjusting the distance between the two sets of clamping rings 23 so that the two sets of clamping rings 23 assist the push rod 20 in fixing the gear. An oil groove 25 is opened in the push rod 20. A piston tube 26 is slidably installed in the push rod 20. The piston tube 26 is slidably connected to the push rod 20 through the oil groove 25. A second threaded rod 27 is rotatably installed in the push rod 20. The upper end of the second threaded rod 27 passes through the piston tube 26 and is threadedly connected to the piston tube 26. The motor in the push rod 20 drives the second threaded rod 27 to rotate, causing the piston tube 26 to slide into the push rod 20, squeezing the hydraulic oil in the oil groove 25, achieving a slight expansion of the push rod 20, and strengthening the fixing strength between the four sets of push rods 20 and the gear.

[0025] This utility model provides a gear cleaning device, the specific working principle of which is as follows: Based on the model of the gear to be cleaned, the motor in the mounting base 3 is started to drive the first threaded rod 6 to rotate. Under the limiting action of the mounting base 3, the moving frame 5 slides within the mounting base 3 until the side plate is in contact with the gear tooth surface. The motor in the fixed frame 7 is started to drive the bidirectional lead screw 10 to rotate. Under the cooperation of the synchronous belt 12 and the synchronous pulley 11 in the fixed frame 7, the two sets of bidirectional lead screws 10 rotate synchronously. Under the limiting action of the fixed frame 7, the distance between the two sets of face brushes 9 is adjusted, so that the two sets of face brushes 9 are in contact with both sides of the gear. The gear, side brushes 8, and face brushes 9 below the mounting base 3 are all placed in the water tank 2, which contains cleaning fluid. The gear rotates at a constant speed under the drive of the mounting rod 17. The motor in the moving frame 5 drives the cam 16 to rotate. The cam 16 intermittently pushes the slider 14, and under the action of the spring 15, the slider 14 drives the fixed frame 7 to reciprocate on the moving frame 5. During the movement, the two sets of face brushes 9 and side brushes 8 rotate... During the movement, the upper and lower surfaces of the gears and the sides of the teeth are cleaned synchronously, ensuring cleaning effect and improving cleaning efficiency. Impurities on the gears adhering to the face brush 9 and side brush 8 fall into the cleaning fluid during the left and right vibration. The second cylinder 19 in the mounting rod 17 drives the adjusting rod 18 to slide, changing the angle of the first adjusting bracket 21 and the second adjusting bracket 22 between the abutment rod 20 and the mounting rod 17 and the adjusting rod 18. This changes the distance between the four sets of abutment rods 20 and the mounting rod 17, so that the four sets of abutment rods 20 are in contact with the inner ring surface of the gear to be fixed. The motor in the abutment rod 20 drives the rotation of the bidirectional screw 24, adjusting the distance between the two sets of clamping rings 23, so that the two sets of clamping rings 23 assist the abutment rod 20 in fixing the gear. The motor in the abutment rod 20 drives the second threaded rod 27 to rotate, causing the piston tube 26 to slide into the abutment rod 20, squeezing the hydraulic oil in the oil groove 25, achieving a slight expansion of the abutment rod 20, and strengthening the fixing strength between the four sets of abutment rods 20 and the gear.
