Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and specifically to a ball cage cleaning machine. Background Technology

[0002] In the field of machinery manufacturing, the cleanliness of ball cages, as an important component, directly affects the performance and service life of the equipment. In the existing technology, there are various cleaning equipment for cleaning components.

[0003] For example, the authorized invention patent (patent number: 200420110888.6) discloses a rotary multi-functional bearing cleaning machine, which uses a stainless steel rotary cage to transport workpieces. The workpieces move forward by their own weight and the inclination of the rotary cage, while high-pressure spraying is performed using nozzles installed at the top to remove oil and dust from the workpieces. However, this cleaning machine has certain limitations when cleaning parts with special structures, such as ball cages.

[0004] The ball cage has a complex internal structure with multiple narrow chambers and precise mating surfaces. Rotary drum cleaning machines cannot penetrate every corner of the ball cage for comprehensive and meticulous cleaning, failing to meet the high cleanliness requirements of the ball cage. Moreover, this type of cleaning machine is mainly designed for general workpieces other than shafts, and lacks a specific design for cleaning the ball cage, resulting in a need to improve cleaning efficiency and quality.

[0005] Therefore, developing a high-efficiency and precise cleaning machine specifically designed for cleaning ball cages is of great practical significance. Summary of the Invention

[0006] The present invention aims to solve one of the technical problems existing in the prior art.

[0007] This application provides a ball cage cleaning machine, including a machine body, an internal rinsing device, and an external rinsing device. The internal rinsing device includes several rinsing units, each of which is connected to a lower water inlet pipe and arranged in two rows. The two rows of rinsing units are synchronously driven to rotate by a drive device. Each rinsing unit includes a water supply shell and a rotating water outlet pipe. The water supply shell is fixed in the machine body and connected to the lower water inlet pipe. The rotating water outlet pipe is rotatably installed in the machine body and is connected to the drive device. A water outlet channel is provided in the peripheral wall. The top end of the water outlet channel is connected to the top end of the rotating water outlet pipe, and the bottom end is connected to the inner cavity of the water supply shell.

[0008] The rinsing unit also includes a lifting pipe, which is movably installed in the inner cavity of the rotating water outlet pipe and can only move up and down along the axis of the rotating water outlet pipe. The top of the lifting pipe is provided with a suction cup, and the bottom is provided with a lifting component and a negative pressure component. The lifting component is used to control the lifting of the lifting pipe when it rotates forward and backward with the rotating water outlet pipe. The negative pressure component is used to reduce or increase the air pressure in the suction cup when the lifting pipe moves up and down.

[0009] The driving device includes a worm and several worm wheels. The worm wheels are fixed on the rotating water outlet pipe. The worm is driven by a motor to drive each worm wheel to rotate synchronously.

[0010] The negative pressure assembly includes a piston cylinder and a piston ring. The piston cylinder is fixed at the bottom of the inner cavity of the machine body and has an exhaust hole on its top peripheral wall. The piston ring is fixed at the bottom end of the lifting pipe and is slidably installed in the inner cavity of the piston cylinder.

[0011] A sealing ring is embedded in the outer peripheral wall of the piston ring.

[0012] The lifting assembly includes a fixed cylinder, an upper ring groove, a lower ring groove, a spiral groove, a pair of one-way sealing units, and a transmission block. The fixed cylinder is fixed to the bottom of the water supply shell and sleeved on the outside of the lifting pipe. The upper ring groove and the lower ring groove are respectively located at the top and bottom of the inner cavity of the fixed cylinder and are connected to each other through the spiral groove. The pair of one-way sealing units are respectively located in the upper ring groove and the lower ring groove to prevent the transmission block from disengaging from the upper ring groove or the lower ring groove when rotating forward or backward. The transmission block is fixed to the outer wall of the lifting pipe.

[0013] The unidirectional sealing unit includes a slot, a floating block, a pressing surface, and a guiding surface. The slot is formed on the side wall of the fixed cylinder and connects to the upper or lower annular groove. The floating block is floatingly installed in the slot by a reset component, with its inner end extending into the upper or lower annular groove. The pressing surface is located on the side of the inner end of the floating block away from the spiral groove, and the guiding surface is located on the side of the inner end of the floating block facing the spiral groove.

[0014] The pressing surface is inclined and parallel to the axis of the lifting tube, and the guiding surface is an extension of the corresponding side wall of the spiral groove and is radially parallel to the lifting tube.

[0015] The reset component includes an upper plate, a lower plate, a fastener, a slide groove, and a reset spring. The upper plate and the lower plate are both fixed on the outer wall of the fixed cylinder and are located above and below the slot, respectively. The slide groove is formed on the floating block. The fastener passes through the upper plate, the lower plate, and the slide groove, is fixed to the upper plate and the lower plate, and slides with the slide groove. The reset spring is disposed between the inner end of the slide groove and the fastener.

[0016] The external flushing device includes two rows of upper water inlet pipes and a corresponding number of water outlet nozzles for the internal flushing units. The water outlet nozzles are installed on the lower water inlet pipes with their outlets facing the internal flushing units. The beneficial effects of this invention are as follows: More targeted and adaptable to the complex structure of ball cages: Existing rotary drum cleaning machines are mainly designed for general workpieces other than shafts, lacking specific design for components like ball cages with complex internal structures, multiple narrow chambers, and precision mating surfaces. This application, however, utilizes a multi-row rotating flushing unit within the internal flushing device to penetrate deep into the ball cage and perform comprehensive flushing from different angles. Specifically adapted to the unique structure of the ball cage, it solves the problem of existing technologies struggling to clean the internal corners of the ball cage. 1. More comprehensive and efficient internal cleaning: Existing technologies rely on high-pressure spraying from cross nozzles, which has limited coverage of the rinsing inside the ball cage. In this application, the rotating water outlet pipe of the internal rinsing device can rotate synchronously with the drive device. At the same time, combined with the lifting and lowering movement of the lifting pipe, it can drive the ball cage adsorbed by the suction cup to perform multi-dimensional movement, so that the rinsing water can reach all parts inside the ball cage, greatly improving the comprehensiveness and efficiency of internal cleaning. 2. External cleaning works in tandem for higher overall cleanliness: Existing cleaning methods focus on overall spraying, which is insufficient for targeted rinsing of the outside of the ball cage. The external rinsing device of this application is equipped with water nozzles corresponding to the number of internal rinsing units, and the water outlets face the internal rinsing units. While cleaning the inside, the outside of the ball cage is precisely rinsed, achieving coordinated internal and external cleaning and thoroughly removing stains. Compared with existing technologies, this significantly improves the overall cleanliness of the ball cage. 3. More reliable workpiece fixation, avoiding displacement during cleaning: In the prior art, the workpiece moves by its own weight and the inclination of the rotating cage, which is prone to positional displacement during cleaning and affects the cleaning effect. This application controls the air pressure of the suction cup through the negative pressure component, adsorbs and fixes the ball cage when the lifting tube rises, and releases the fixation when it descends, ensuring that the ball cage is stable in position during cleaning and solving the problem of insufficient cleaning caused by workpiece displacement in the prior art. 4. More precise structural design and more stable operation: The existing rotary cage structure has relatively simple driving and control of the components. This application realizes the synchronous rotation of each rotating water outlet pipe through a worm gear drive device to ensure consistent rinsing; the lifting assembly precisely controls the lifting trajectory of the lifting pipe through structures such as spiral grooves, transmission blocks and one-way sealing units; the reset component ensures the stable reset of the floating block. The overall structure has a rigorous operating logic and is more stable and precise than the existing technology. 5. Adaptable to different specifications of ball cages, with greater flexibility: Existing technologies have limited adaptability to workpieces of different specifications. This application can change the rotation speed of the rotating water outlet pipe by adjusting the motor speed, thereby controlling the lifting frequency of the lifting pipe and the adsorption timing of the suction cup, adapting to the cleaning needs of ball cages of different specifications. Compared with existing technologies, it has greater flexibility and versatility. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0020] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0021] The ball cage cleaning machine provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0022] Example 1: This application provides a ball cage cleaning machine, including a body 1, an internal rinsing device and an external rinsing device 2. The internal rinsing device includes several rinsing units 3, each of which is connected to a lower water inlet pipe 4 and arranged in two rows. The two rows of rinsing units 3 are synchronously driven to rotate by a driving device 5. Each rinsing unit 3 includes a water supply shell 31 and a rotating water outlet pipe 32. The water supply shell 31 is fixed inside the body 1 and connected to the lower water inlet pipe 4. The rotating water outlet pipe 32 is rotatably installed inside the body 1 and is connected to the driving device 5. A water outlet channel 33 is provided in the peripheral wall. The top end of the water outlet channel 33 is connected to the top end of the rotating water outlet pipe 32, and the bottom end is connected to the inner cavity of the water supply shell 31.

[0023] like Figures 1 to 9 As shown, due to the above structure, when the ball cage cleaning machine is started, the lower water inlet pipe 4 delivers water to each rinsing unit 3 of the inner rinsing device. Since the two rows of rinsing units 3 are driven to rotate synchronously by the drive device 5, the rotating water outlet pipe 32 starts to rotate under the action of the drive device 5. The water supply shell 31 is fixed inside the machine body 1 and connected to the lower water inlet pipe 4. The water flows through the lower water inlet pipe 4 into the inner cavity of the water supply shell 31, and then enters the water outlet channel 33 in the peripheral wall of the rotating water outlet pipe 32 through the connection between the bottom end of the rotating water outlet pipe 32 and the inner cavity of the water supply shell 31. Finally, it sprays out from the top of the rotating water outlet pipe 32 to rinse the ball cage internally. The two rows of rotating rinsing units 3 can rinse the inside of the ball cage from different angles, improving the cleaning effect.

[0024] Example 2: The difference from Embodiment 1 is that, in this embodiment, in addition to the structural features of the aforementioned embodiments, the flushing unit 3 also includes a lifting pipe 34. The lifting pipe 34 is movably installed in the inner cavity of the rotating water outlet pipe 32 and can only move up and down along the axis of the rotating water outlet pipe 32. The top end of the lifting pipe 34 is provided with a lifting pipe 35, and the bottom end is provided with a lifting component 9 and a negative pressure component 6. The lifting component 9 is used to control the lifting pipe 34 to move up and down when it rotates forward and backward with the rotating water outlet pipe 32. The negative pressure component 6 is used to reduce or increase the air pressure in the lifting pipe 35 when the lifting pipe 34 moves up and down.

[0025] In this embodiment of the application, the driving device 5 includes a worm 51 and a plurality of worm wheels 52. The worm wheels 52 are fixed on the rotating water outlet pipe 32. The worm 51 is driven by a motor to drive each worm wheel 52 to rotate synchronously.

[0026] like Figures 2 to 8 As shown, due to the above-mentioned structure, the rinsing unit 3 adds a lifting pipe 34, a lifting assembly 9, and a negative pressure assembly 6. When the drive device 5 drives the rotating water outlet pipe 32 to rotate forward or backward, the lifting assembly 9 controls the lifting pipe 34 to rise and fall along the axis of the rotating water outlet pipe 32 according to the rotation direction. At the same time, during the rising and falling of the lifting pipe 34, the negative pressure assembly 6 operates. When the lifting pipe 34 rises, the negative pressure assembly 6 reduces the air pressure in the lifting pipe 35, which facilitates the lifting pipe 35 to contact the ball cage and fix the ball cage at the top of the lifting pipe 34. When the lifting pipe 34 falls, the negative pressure assembly 6 increases the air pressure in the lifting pipe 35, releases the fixation of the ball cage, and prevents the ball cage from shifting during the cleaning process. In the drive device 5, the motor drives the worm gear 51 to rotate, and the worm gear 51 drives each worm wheel 52 meshing with it to rotate synchronously, thereby realizing the synchronous rotation of each rotating water outlet pipe 32 and ensuring the consistency of rinsing.

[0027] The adjacent peripheral walls of the riser pipe 34 and the rotating water outlet pipe 32 are limited by protrusions and grooves to ensure that the riser pipe 34 can only slide along the axis of the rotating water outlet pipe 32 and can rotate together with the rotating water outlet pipe 32. The riser pipe 35 is made of rubber and has a closed bottom. This design can prevent water from flowing back. In addition, because the material of the riser pipe 35 is elastic, when the riser pipe 35 contacts the inner cavity of the ball cage, under the action of the negative pressure component 6, the bottom of the riser pipe 35 will deform downward, the volume of the inner cavity will increase, the pressure will decrease, and it will have the effect of sucking the inner wall of the ball cage.

[0028] Example 3: The difference from Embodiment 2 is that, in this embodiment, in addition to the structural features of the aforementioned embodiments, the negative pressure assembly 6 includes a piston cylinder 61 and a piston ring 62. The piston cylinder 61 is fixed to the bottom of the inner cavity of the machine body 1 and has an exhaust hole on the top peripheral wall. The piston ring 62 is fixed to the bottom end of the lifting pipe 34 and is slidably installed in the inner cavity of the piston cylinder 61.

[0029] In this embodiment of the application, a sealing ring 63 is embedded in the outer peripheral wall of the piston ring 62.

[0030] like Figures 5 to 8 As shown, due to the above-mentioned structure, the negative pressure component 6 specifically consists of a piston cylinder 61 and a piston ring 62. When the lifting pipe 34 rises or falls, the piston ring 62, fixed at the bottom end of the lifting pipe 34, slides in a sealed manner within the inner cavity of the piston cylinder 61. When the lifting pipe 34 rises, the piston ring 62 moves upward, increasing the space below the piston ring 62 within the piston cylinder 61 and reducing the air pressure. This reduces the air pressure within the lifting pipe 35 through relevant channels, fixing the ball cage to the top of the lifting pipe 34 and causing it to rotate with the lifting pipe 34. When the lifting pipe 34 falls, the piston ring 62 moves downward, reducing the space within the piston cylinder 61 and increasing the air pressure. This pressure is transmitted to the lifting pipe 35 through channels, increasing the air pressure within the lifting pipe 35 and releasing the adsorption on the ball cage. The sealing ring 63 embedded in the outer peripheral wall of the piston ring 62 enhances the sealing between the piston ring 62 and the piston cylinder 61, ensuring the effectiveness of air pressure changes and ensuring the reliable operation of the negative pressure component 6.

[0031] Example 4: The difference from Embodiment 3 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the lifting assembly 9 includes a fixed cylinder 91, an upper annular groove 92, a lower annular groove 93, a spiral groove 94, a pair of one-way sealing units 7, and a transmission block 95. The fixed cylinder 91 is fixed to the bottom of the water supply shell 31 and sleeved on the outside of the lifting pipe 34. The upper annular groove 92 and the lower annular groove 93 are respectively disposed at the top and bottom of the inner cavity of the fixed cylinder 91 and are connected to each other through the spiral groove 94. The pair of one-way sealing units 7 are respectively disposed in the upper annular groove 92 and the lower annular groove 93 to prevent the transmission block 95 from disengaging from the upper annular groove 92 or the lower annular groove 93 when rotating forward or backward. The transmission block 95 is fixed to the outer wall of the lifting pipe 34.

[0032] In this embodiment of the application, the one-way sealing unit 7 includes a slot 71, a floating block 72, a pressing surface 73, and a guiding surface 74. The slot 71 is formed on the side wall of the fixed cylinder 91 and communicates with the upper annular groove 92 or the lower annular groove 93. The floating block 72 is floatingly installed in the slot 71 by a reset member 8, with its inner end extending into the upper annular groove 92 or the lower annular groove 93. The pressing surface 73 is located on the side of the inner end of the floating block 72 away from the spiral groove 94, and the guiding surface 74 is located on the side of the inner end of the floating block 72 facing the spiral groove 94.

[0033] In this embodiment of the application, the pressing surface 73 is inclined and parallel to the axis of the lifting tube 34, and the guiding surface 74 is an extension of the corresponding sidewall of the spiral groove 94 and is radially parallel to the lifting tube 34.

[0034] like Figures 5 to 9As shown, due to the aforementioned structure, the fixed cylinder 91 of the lifting assembly 9 is sleeved on the outside of the lifting pipe 34. When the rotating outlet pipe 32 drives the lifting pipe 34 to rotate clockwise, the transmission block 95 fixed on the outer wall of the lifting pipe 34 rotates along the lower annular groove 93 and is guided into the spiral groove 94 by the guide surface 74 on the lower floating block 72. It moves from the lower annular groove 93 to the upper annular groove 92, driving the lifting pipe 34 to rise. It continues to rotate in the upper annular groove 92. When it passes the upper floating block 72, it cooperates with the pressing surface 73 to push the upper floating block 72 out of the upper annular groove 92. When the transmission block 95 leaves the upper pressing block, under the action of the reset member 8, the upper floating block 72 re-enters the upper annular groove 92. This process repeats, ensuring that the lifting pipe 34 does not leave the upper annular groove 92 when rotating clockwise. Conversely, when the lifting pipe 34 rotates counterclockwise, the transmission block 95 rotates counterclockwise in the upper annular groove 92 until it contacts the guide surface 74 of the upper floating block 72. Guided by the upper guide surface 74 into the spiral groove 94, as the lifting tube 34 reverses, the transmission block 95 moves towards the lower end of the spiral groove 94 until it enters the lower ring groove 93. When the lifting tube 34 continues to reverse, the transmission block 95 rotates continuously in the lower ring groove 93. When it passes the lower floating block 72, it cooperates with the pressing surface 73 to push the lower floating block 72 out of the upper ring groove 92. When the transmission block 95 leaves the lower pressing block, under the action of the reset member 8, the lower floating block 72 re-enters the lower ring groove 93. This process repeats, so that the lifting tube 34 will not leave the upper ring groove 92 when rotating forward. In the one-way blocking unit 7, the floating block 72 is floatingly installed through the reset member 8. When the transmission block 95 enters the upper ring groove 92 or the lower ring groove 93 from the spiral groove 94, it pushes the floating block 72 back into the slot 71 along the guide surface 74. After entering, the floating block 72 extends under the action of the reset member 8, and the pressing surface 73 prevents it from reversing and detaching, thus realizing lifting control.

[0035] Example 5: The difference from Embodiment 4 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the reset component 8 includes an upper plate 81, a lower plate 82, a fastener 83, a slide groove 84, and a reset spring. The upper plate 81 and the lower plate 82 are both fixed on the outer wall of the fixed cylinder 91 and are located above and below the slot 71, respectively. The slide groove 84 is formed on the floating block 72. The fastener 83 passes through the upper plate 81, the lower plate 82, and the slide groove 84, is fixed to the upper plate 81 and the lower plate 82, and slides in cooperation with the slide groove 84. The reset spring is disposed between the inner end of the slide groove 84 and the fastener 83.

[0036] like Figures 6 to 7As shown, due to the above structure, the upper plate 81 and lower plate 82 of the reset component 8 are fixed to the outer wall of the fixed cylinder 91. The fastener 83 (selected as a pin or bolt) passes through it and slides in cooperation with the slide groove 84, restricting the movement direction of the floating block 72. When the floating block 72 is pushed by the transmission block 95, the inner end of the slide groove 84 compresses the reset spring, and the floating block 72 retracts. After the transmission block 95 passes, the reset spring extends and pushes the floating block 72 out of the slot 71, realizing the one-way blocking reset function, ensuring that the floating block 72 can work effectively and stably control the movement trajectory of the transmission block 95.

[0037] It should be noted that the upper reset piece 8 is close to the water supply shell 31. In actual manufacturing, the bottom of the water supply shell 31 is used as the upper plate 81 of the upper reset piece 8. Correspondingly, the lower reset piece 8 is close to the piston cylinder 61. In actual manufacturing, the top of the piston shell is used as the lower plate 82 of the lower reset piece 8.

[0038] Example 6: The difference from Embodiment 5 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the external flushing device 2 includes two rows of upper water inlet pipes 21 and a number of water outlet nozzles 22 corresponding to the number of internal flushing units 3. The water outlet nozzles 22 are installed on the lower water inlet pipe 4 and the water outlet ends face the internal flushing units 3.

[0039] like Figures 1 to 4 As shown, due to the above structure, the two rows of upper water inlet pipes 21 of the external rinsing device 2 supply water to the water outlet nozzles 22. The number of water outlet nozzles 22 corresponds to the number of internal rinsing units 3 and the water outlet ends face the internal rinsing units 3. When the internal rinsing unit 3 rinses the inside of the ball cage, the water outlet nozzles 22 of the external rinsing device 2 simultaneously spray water flow to the outside of the ball cage. The internal and external rinsing work together. The internal rinsing unit 3 rotates and rises to achieve all-round cleaning inside, while the external rinsing washes from multiple angles outside, thoroughly removing stains inside and outside the ball cage, greatly improving cleaning efficiency and cleanliness.
