Description

Technical Field

[0001] This utility model belongs to the field of ball cage assembly processing technology, and particularly relates to a flushing structure for ball cage assembly processing. Background Technology

[0002] The CV joint, also known as a constant velocity joint, is an important component in the transmission system of a car. Its function is to transmit the engine's power from the transmission to the drive wheels, driving the car at high speeds. There are many types of constant velocity joints used in cars, among which the most commonly used are the CV joint and the tripod type. It mainly consists of a sliding sleeve, a three-way shaft, a drive shaft, a star-shaped sleeve, a cage, and a bell-shaped housing. Because constant velocity joints transmit heavy driving torque, are subject to heavy loads, have high transmission accuracy, and are in high demand, and are also safety components, their main parts are all made of precision forgings. During the machining process of the CV joint, the surface of the CV joint needs to be cleaned.

[0003] In the prior art, Chinese utility model patent CN207899790U discloses a rinsing device for ball cage processing, including a rinsing box. Two sets of transmission screws are horizontally inserted into the inner cavity of the rinsing box, and a ball cage fixing seat is horizontally inserted between the two sets of transmission screws. A stepper motor is installed on the right wall of the rinsing box. The power output end of the stepper motor is connected to the right end of the ball cage fixing seat via a rotating shaft. A first transmission belt and a second transmission belt are respectively connected to the outer wall of the rotating shaft. A sliding screw block is screwed onto the transmission screw. Connecting parts are installed on the front and rear side walls of the sliding screw block, and one end of the connecting part is slidably connected to the front and rear side walls of the inner cavity of the rinsing box. A rotating rinsing head is installed on the outer wall of the sliding screw block. A water tank is installed on the left wall of the rinsing box, ensuring comprehensive cleaning of the ball cage, recycling water resources, greatly saving water resources, providing fast cleaning, convenient operation, and greatly improving the processing efficiency of the ball cage.

[0004] In existing technologies, the symmetrically arranged transmission screws, sliding screw blocks, and rotating flushing heads ensure comprehensive cleaning of the ball cages and greatly improve the processing efficiency of the ball cages. However, there are still some shortcomings in overall use:

[0005] First, after the ball cage is rinsed, there will be residual moisture on the surface. If it is not dried in time, the residual moisture will cause the inside of the ball cage to rust. If the moisture remains for a long time, it will corrode the metal material of the ball cage, thereby reducing the service life of the ball cage.

[0006] Secondly, in the aforementioned existing technology, the surface of the transmission lead screw is constantly in contact with water and cleaning agents during use. If the lead screw remains exposed to water and cleaning agent residue for an extended period without timely removal, the moisture will react with the metal material of the lead screw, leading to rust and reducing its mechanical properties. Utility Model Content

[0007] This invention addresses the technical problems of residual moisture on the surface of ball cages after rinsing, failure to dry them in time, reduced service life of the ball cages, and compromised mechanical performance of the lead screws. It provides a rinsing structure for ball cage assembly processing.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a flushing structure for processing a ball cage assembly, comprising a cleaning tank, a housing fixedly installed on the top of the cleaning tank, a bearing fixedly installed in the inner cavity of the housing, a threaded sleeve fixedly installed on the inner ring of the bearing, a threaded rod installed on the internal thread of the threaded sleeve, and a spray head provided at the bottom end of the threaded rod;

[0009] A drive shaft is rotatably mounted inside the housing and on one side of the bearing, and a transmission assembly is provided between the drive shaft and the threaded sleeve.

[0010] The cleaning tank has a fixed mounting box on the upper surface of its inner cavity. A lead screw is rotatably mounted inside the mounting box. A clamping mechanism is threaded onto the surface of the lead screw for clamping and rotating the ball cage.

[0011] A second bevel gear is fixedly installed at one end of the lead screw, and a first bevel gear that meshes with the second bevel gear is fixedly installed at the bottom end of the drive shaft through the mounting box.

[0012] The rotation of the drive shaft, through the transmission assembly and the second and first bevel gears, simultaneously drives the lead screw and threaded rod to rotate. This causes the ball cage held by the spray head to move towards the spray head as it moves downwards, rinsing the ball cage at a suitable distance, greatly improving the rinsing effect. After rinsing, the ball cage is returned to the drying area for drying, which can remove moisture from the surface of the ball cage in time, prevent moisture from corroding the ball cage, and greatly improve the service life of the ball cage. At the same time, after rinsing, the spray head is separated from the ball cage, which facilitates the disassembly and assembly of the ball cage and improves work efficiency.

[0013] In the above-mentioned flushing structure for processing the ball cage assembly, the clamping mechanism includes two movable plates threaded onto the surface of the lead screw. A side plate is fixedly installed on the upper surface of the movable plate, and a turntable is rotatably installed on the opposite surface of the side plate. An electric telescopic rod is fixedly installed on the surface of the turntable, and a U-shaped clamping plate is fixedly installed at the output end of the electric telescopic rod for clamping the connection of the ball cage hole.

[0014] The U-shaped clamps can center and hold the ball cage while reducing the contact area, allowing the ball cage to be thoroughly rinsed and improving the rinsing effect. By rotating the clamped ball cage, the dead corners of the ball cage can be thoroughly rinsed, greatly improving the rinsing effect.

[0015] In the above-mentioned flushing structure for the ball cage assembly, the transmission component includes two pulleys that are fixedly connected to the drive shaft and the threaded sleeve, respectively, and the two pulleys are connected by belt drive.

[0016] By configuring the transmission components, the movement of the spray head and the clamping ball cage can be kept consistent, avoiding deviations and greatly improving the performance.

[0017] In the flushing structure of the ball cage assembly processing described above, the upper surface of the mounting box is provided with a sliding groove for the sliding plate to slide, and a baffle is fixedly installed in the middle of the sliding plate to seal the sliding groove.

[0018] By setting up the baffle, the slide groove can be sealed during ball cage washing, preventing washing water from seeping into the surface of the lead screw through the slide groove and affecting the mechanical properties of the lead screw.

[0019] In the flushing structure of the ball cage assembly described above, a mounting plate is rotatably mounted on the bottom of the threaded rod, and the mounting plate slides on the top of the inner cavity of the cleaning tank.

[0020] The threaded rod is limited by the mounting plate, allowing it to move downwards as the threaded sleeve rotates.

[0021] In the above-mentioned flushing structure for the ball cage assembly, a water tank is fixedly installed in the middle of the upper surface of the cleaning box, and a telescopic pipe is connected to one side of the water tank, which is connected to the spray head.

[0022] In the above-mentioned flushing structure for the ball cage assembly, a heater is fixedly installed on the upper surface of the cleaning tank and on one side of the water tank, and the air outlet of the heater is located inside the cleaning tank.

[0023] The warm air blower can dry the ball cage in time after rinsing, remove moisture in time, prevent the metal material of the ball cage from being corroded, and greatly improve the service life of the ball cage.

[0024] In the above-mentioned flushing structure for the ball cage assembly, a drain pipe is connected to one side of the cleaning tank for discharging flushing wastewater and ventilation.

[0025] In summary, compared with the prior art, the flushing structure for the processing of the ball cage assembly provided by this utility model has the following beneficial effects:

[0026] 1. This utility model, through the setting of bearings, threaded sleeves, threaded rods, mounting plates, spray heads, lead screws and clamping mechanisms, can make the ball cage and the spray head at a suitable rinsing distance, which greatly improves the rinsing effect. At the same time, after rinsing, it can automatically return to the drying area for drying, so as to remove the moisture on the surface of the ball cage in time, prevent moisture from corroding the ball cage, and greatly improve the service life of the ball cage.

[0027] 2. This utility model, through the setting of side plates, turntable, electric telescopic rod and clamping plate, can center and clamp the ball cage with a reduced contact surface, so that the ball cage can be thoroughly rinsed and the rinsing effect can be improved. At the same time, the ball cage can be rotated during the cleaning process to thoroughly rinse the dead corners of the ball cage, which greatly improves the rinsing effect and speeds up the work efficiency.

[0028] 3. This utility model, by setting up a baffle, can seal the slide groove during ball cage washing, preventing washing water from seeping into the surface of the lead screw through the slide groove and affecting the mechanical properties of the lead screw. Attached Figure Description

Detailed Implementation

[0037] To enable those skilled in the art to better understand the present invention, 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.

[0038] refer to Figure 1 A flushing structure for processing a ball cage assembly includes a base 10, a cleaning tank 11 fixedly mounted on the upper surface of the base 10, a door hinged to the front surface of the cleaning tank 11, a water tank 31 for flushing the workpiece fixedly mounted in the middle of the upper surface of the base 10, a water inlet pipe connected to the top of the water tank 31, and a water pump installed inside the water tank 31. The water pump is prior art and will not be described in detail in this solution.

[0039] Further reference Figure 2 , Figure 3 and Figure 6 An installation box 12 is fixedly installed on the upper surface of the inner cavity of the cleaning box 11. A lead screw 13 is rotatably installed inside the installation box 12. A sliding groove 20 is opened on the upper surface of the installation box 12. Two movable plates 14 that slide inside the sliding groove 20 are threaded on the surface of the lead screw 13.

[0040] Specifically, when the lead screw 13 rotates, the movable plate 14 is limited by the slide groove 20, allowing the two movable plates 14 to slide in the slide groove 20.

[0041] Further reference Figure 6 Side plates 15 are fixedly installed on the top of the two movable plates 14. A motor 16 is fixedly installed on the outer side of the side plates 15. A turntable 17 driven by the motor 16 is rotatably installed on the inner side of the side plates 15. An electric telescopic rod 18 is fixedly installed on the opposite side of the two turntables 17. A U-shaped clamping plate 19 is fixedly installed at the output end of the electric telescopic rod 18. The two ends of the clamping plate 19 are inserted into the ball cage, which can center and clamp the ball cage with reduced contact area, so that the ball cage can be fully rinsed and the rinsing effect can be improved.

[0042] Specifically, the ball cage is placed between two clamping plates 19, and the connection point of the ball cage hole is aligned with the clamping plate 19. The electric telescopic rod 18 is controlled to move in the center, which drives the clamping plate 19 to fix the ball cage, making it easier to wash the ball cage. During the washing process, the motor 16 rotates and drives the turntable 17 to rotate, which allows the clamping plate 19 to rotate and the ball cage to rotate, thoroughly washing the dead corners of the ball cage, greatly improving the washing effect and speeding up the work efficiency.

[0043] Further reference Figures 1-4A housing 22 is fixedly installed on the upper surface of the cleaning tank 11 and on one side of the water tank 31. A motor 23 is fixedly installed on the inner top wall of the housing 22. A drive shaft 29 is fixedly installed at the output end of the motor 23. A bearing 24 is fixedly installed on the upper surface of the inner cavity of the housing 22. A threaded sleeve 25 is fixedly installed on the inner ring of the bearing 24. A threaded rod 26 is installed on the internal thread of the threaded sleeve 25. A transmission assembly 30 is installed between the drive shaft 29 and the threaded sleeve 25. The transmission assembly 30 includes two pulleys fixedly installed on the drive shaft 29 and the threaded sleeve 25 respectively. The two pulleys are connected by a belt drive. A mounting plate 27 is rotatably installed on the bottom end of the threaded rod 26 and slidably installed on the top of the inner cavity of the cleaning tank 11. A spray head 28 is fixedly installed on the lower surface of the mounting plate 27. A telescopic pipe 32 is connected to the top end of the spray head 28 and is connected to the outlet end of the water pump in the water tank 31.

[0044] Specifically, when the motor 23 rotates, it drives the transmission shaft 29 connected to it to rotate. The transmission shaft 29 drives the threaded sleeve 25 to rotate through the transmission assembly 30. When the threaded sleeve 25 rotates, the threaded rod 26 inside it rotates downward, thereby driving the mounting plate 27 to move downward, which in turn drives the spray head 28 to move downward as well, reaching a suitable height with the ball cage to rinse the ball cage. The spray head 28 maintains a suitable height with the ball cage to rinse it, which greatly improves the rinsing effect of the ball cage.

[0045] Further reference Figure 3 and Figure 7 The bottom end of the drive shaft 29 passes through the upper surface of the mounting box 12 and is rotatably engaged. A first bevel gear 33 is fixedly installed at the end of the shaft. A second bevel gear 34 that meshes with the first bevel gear 33 is fixedly installed at one end of the clamping plate 19.

[0046] Specifically, while the motor 23 rotates and drives the spray head 28 to move downward, the transmission shaft 29 drives the first bevel gear 33 connected to it to rotate. Since the first bevel gear 33 meshes with the second bevel gear 34, the second bevel gear 34 rotates, which in turn drives the lead screw 13 to rotate, moving the clamped ball cage towards the spray head 28. When the ball cage is directly below the spray head 28, it stops moving and is then rinsed. After the ball cage is rinsed, the spray head 28 moves upward, and the ball cage returns to its original position, so that there is no obstruction above the ball cage, which facilitates the disassembly and assembly of the ball cage during rinsing and greatly improves work efficiency.

[0047] Furthermore, a heater 36 is fixedly installed on the upper surface of the cleaning tank 11 and on the other side of the water tank 31. The air outlet of the heater 36 is located inside the cleaning tank 11 and is correspondingly set to the ball cage.

[0048] Specifically, after the ball cage is rinsed, the motor 23 rotates in the reverse direction to reset the spray head 28, thereby resetting the ball cage to below the heater 36. This allows the heater 36 to dry the rinsed ball cage in time, remove moisture, prevent corrosion of the metal material of the ball cage, and greatly improve the service life of the ball cage.

[0049] Further reference Figure 3 , Figure 5 and Figure 6 A baffle 21 is fixedly installed in the middle of the movable plate 14 and slides on the upper surface of the mounting box 12. The baffle 21 is located directly above the slide groove 20, and the baffle 21 and the slide groove 20 are in a sealed state.

[0050] Specifically, when the moving plate 14 moves the ball cage, it can move the baffle 21, so that when the ball cage is being cleaned, the baffle 21 can cover the upper surface of the slide groove 20 to seal it, preventing the rinsing water from seeping into the surface of the lead screw 13 through the slide groove 20 and affecting the mechanical properties of the lead screw 13.

[0051] Furthermore, a drain pipe 35 is connected to one side of the cleaning tank 11 for the discharge of flushing wastewater and ventilation.
