Description

A cleaning device for gear shaft machining Technical Field

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

[0002] Gear shafts are key components in mechanical transmission systems, mainly used to connect and support gears and transmit power and torque. The overall structure is cylindrical. During the processing, metal shavings, dust and other impurities will remain on the surface of the gear shaft, affecting assembly and subsequent operation and installation. Gear shaft processing and cleaning devices are a type of equipment specifically designed to assist in cleaning gear shafts.

[0003] Comparative document: A cleaning device for gear shaft processing, publication number: CN221333057U. When the filter screen needs to be cleaned after long-term use, the control limit mechanism can remove the filter screen, which makes it easy to clean the filter screen. Compared with the traditional thread mechanism, this structure is more convenient and does not require finding a screwdriver of the appropriate size to unscrew the bolts one by one, which can save a certain amount of time.

[0004] The aforementioned device directly places multiple gear shafts in a single batch into the cleaning device for rotation and cleaning during the cleaning process. However, the collisions between the gear shafts during the cleaning process can easily damage their outer surfaces. In addition, the impurities in the existing cleaning device are not easy to remove all at once. Therefore, an innovative design is made based on the original gear shaft cleaning device. Summary of the Invention

[0005] The purpose of this utility model is to provide a cleaning device for gear shaft processing, in order to solve the problems mentioned in the background art. The common gear shaft cleaning devices on the market directly put multiple gear shafts in a single batch into the cleaning device for rotation and cleaning. As the gear shafts collide with each other during the cleaning process, their outer surfaces are easily damaged. At the same time, it is inconvenient to remove impurities from the existing cleaning devices at one time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for gear shaft processing, comprising an upper barrel, a lower barrel, a protective cover, and a reinforcing support frame. The upper barrel is fixedly installed above the lower barrel. The upper barrel is configured as a cylindrical structure, and the lower barrel is configured as a funnel structure. A protective cover is threaded onto the upper barrel, and a reinforcing support frame is fixedly installed on the outside of the upper barrel. A cleaning control mechanism is provided above the protective cover. An interval placement mechanism is provided inside the upper barrel, and an auxiliary cleaning and draining mechanism is provided inside the lower barrel.

[0007] Preferably, the cleaning control mechanism includes a positioning support frame, a drive motor, a drive gear, a driven gear, and a support shaft. A "Z"-shaped positioning support frame is fixedly installed on the top outer wall of the protective cover. A drive motor is fixedly installed above the positioning support frame. The output end of the drive motor is connected to the top outer wall of the drive gear. A driven gear is meshed on the side of the drive gear. Both the drive gear and the driven gear are rotatably installed on the top outer wall of the protective cover. The driven gear is fixedly installed through the outside of the support shaft. The top outer wall of the support shaft is rotatably installed on the top inner wall of the positioning support frame. The bottom end of the support shaft penetrates the protective cover and is located inside the upper barrel.

[0008] Preferably, the diameter of the drive gear is smaller than the diameter of the driven gear.

[0009] Preferably, the spaced placement mechanism includes a positioning support bar, a mesh cylinder, a threaded mounting ring, a cap, a limiting cylinder, a limiting piston rod, an abutment spring, and an abutment block. A positioning support bar is circumferentially fixed to the outer wall of the support shaft inside the upper barrel. A mesh cylinder is fixedly installed on the outer wall of the positioning support bar on its side away from the support shaft. A threaded mounting ring is fixedly installed on the outer wall of the top of the mesh cylinder, and a cap is correspondingly installed on the outside of the threaded mounting ring. The cap has an annular threaded groove inside that aligns with the threaded mounting ring. A limiting cylinder is fixedly installed on the inner wall of the top of the cap. A limiting piston rod is slidably installed inside the limiting cylinder. An abutment spring is connected between the limiting piston rod and the inner wall of the bottom end of the limiting cylinder. The protruding end of the limiting piston rod is located outside the limiting cylinder, and the protruding end of the limiting piston rod is connected to the outer wall of the top of the abutment block.

[0010] Preferably, an auxiliary mounting plate is fixedly installed on the bottom outer wall of the support shaft, and three sets of "L"-shaped scrapers are installed at equal intervals around the side outer wall of the auxiliary mounting plate, with the side outer wall of the scrapers fitting against the side inner wall of the upper barrel.

[0011] Preferably, the limiting cylinder is filled with damping fluid, the limiting piston rod is composed of a piston rod and a piston disc, and the outer side wall of the piston disc has a through hole circumferentially through it.

[0012] Preferably, the auxiliary cleaning mechanism includes an annular baffle, a drain pipe, and a control valve. The annular baffle is fixedly installed on the inner side wall of the lower tank and is configured as an inclined structure. A drain pipe is provided through the bottom of the lower tank, and a control valve is provided on the outside of the drain pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the cleaning device for gear shaft machining,

[0014] 1. When using this cleaning device for gear shaft processing, multiple sets of mesh cylinders are set up and placed in a one-cylinder-per-shaft manner to prevent the gear shafts from colliding and being damaged during the cleaning process. Furthermore, the abutment component abuts and limits the gear shafts inside the cylinders, ensuring the stability of the gear shafts and preventing damage during subsequent cleaning. At the same time, the drive component uses a small gear to drive a large gear for transmission output, which increases the output torque of the device and ensures the transmission stability of the subsequent cleaning components. The overall structure is ingeniously designed and has good practical effect.

[0015] 2. When in use, this cleaning device for gear shaft processing synchronously drives multiple sets of scrapers to rotate via the transmission trajectory of the support shaft. During rotation, the scrapers automatically clean the barrel wall. When the protective cover is removed, the scrapers can also serve as a support frame, providing temporary support for the protective cover and cleaning components. This truly achieves a dual-purpose function, with different effects depending on the application environment. Furthermore, by setting a funnel-shaped barrel at the bottom of the device and installing an annular baffle inside, the annular baffle disrupts the backflow path of the cleaning liquid, making it difficult for impurities at the bottom of the device to flow back into the upper barrel. The overall structure is ingeniously designed and has good practical effects. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 6. This utility model provides a technical solution: a cleaning device for gear shaft processing, including an upper barrel 1, a lower barrel 2, a protective cover 3, and a reinforcing support frame 4. The upper barrel 1 is fixedly installed above the lower barrel 2. The upper barrel 1 is configured as a cylindrical structure, and the lower barrel 2 is configured as a funnel structure. The protective cover 3 is threadedly installed on the upper barrel 1, and the reinforcing support frame 4 is fixedly installed on the outside of the upper barrel 1. A cleaning control mechanism 5 is provided above the protective cover 3. An interval placement mechanism 6 is provided inside the upper barrel 1, and an auxiliary cleaning and draining mechanism 7 is provided inside the lower barrel 2.

[0025] The cleaning control mechanism 5 includes a positioning support frame 51, a drive motor 52, a drive gear 53, a driven gear 54, and a support shaft 55. A "Z"-shaped positioning support frame 51 is fixedly installed on the top outer wall of the protective cover 3. A drive motor 52 is fixedly installed above the positioning support frame 51. The output end of the drive motor 52 is connected to the top outer wall of the drive gear 53. A driven gear 54 is meshed with the side of the drive gear 53. Both the drive gear 53 and the driven gear 54 are rotatably mounted to the top outer wall of the protective cover 3. 54 is fixedly installed on the outside of the support shaft 55. The top outer wall of the support shaft 55 is rotatably installed on the top inner wall of the positioning support frame 51. The bottom end of the support shaft 55 passes through the protective cover 3 and is located inside the upper barrel 1. The diameter of the drive gear 53 is smaller than the diameter of the driven gear 54. This design of the drive gear 53 being smaller than the driven gear 54 makes it possible for the drive gear 53 to rotate several times before it drives the driven gear 54 to rotate once. This increases the output torque of the device and ensures the stability of the subsequent mechanical transmission.

[0026] The spaced placement mechanism 6 includes a positioning support bar 61, a mesh cylinder 62, a threaded mounting ring 63, a cover 64, a limiting cylinder 65, a limiting piston rod 66, an abutment spring 67, and an abutment block 68. The positioning support bar 61 is circumferentially fixed to the outer wall of the support shaft 55 inside the upper barrel 1. The mesh cylinder 62 is fixedly installed on the outer wall of the positioning support bar 61 away from the support shaft 55. A threaded mounting ring 63 is fixedly installed on the top outer wall of the mesh cylinder 62, and a cover 64 is correspondingly installed on the outside of the threaded mounting ring 63. The cover 64 has an annular threaded groove inside that aligns with the threaded mounting ring 63. A limiting cylinder 65 is fixedly installed on the top inner wall of the cover 64. A limiting piston rod 66 is slidably installed inside the limiting cylinder 65. An abutment spring is connected between the limiting piston rod 66 and the bottom inner wall of the limiting cylinder 65. 67. The extended end of the limiting piston rod 66 is located outside the limiting cylinder 65, and the extended end of the limiting piston rod 66 is connected to the top outer wall of the contact block 68. An auxiliary mounting plate 69 is fixedly installed on the bottom outer wall of the support shaft 55. Three sets of "L"-shaped scrapers 610 are installed at equal intervals on the side outer wall of the auxiliary mounting plate 69, and the side outer wall of the scraper 610 is in contact with the side inner wall of the upper barrel 1. The limiting cylinder 65 is filled with damping fluid. The limiting piston rod 66 is composed of a piston rod and a piston plate. A through hole is opened on the side outer wall of the piston plate. Here, the limiting cylinder 65 is filled with damping fluid, and a through hole is opened on the outer wall of the piston plate for the damping fluid to flow. The incompressibility of the liquid plays a role in deceleration and protection of the limiting piston rod 66, further improving the durability of the device.

[0027] The auxiliary cleaning and draining mechanism 7 includes an annular baffle 71, a drain pipe 72, and a control valve 73. An annular baffle 71 is fixedly installed on the inner side wall of the lower tank 2, and the annular baffle 71 is designed with an inclined structure. A drain pipe 72 is provided through the bottom of the lower tank 2, and a control valve 73 is installed outside the drain pipe 72. Through the design of the annular baffle 71, when the cleaning liquid inside the device rotates, it is affected by centrifugal force. During rotation, the centrifugal force of the liquid causes the liquid particles to move towards the outer edge, while the surface tension and gravity of the liquid cause the liquid to rise in the center. This competitive effect causes the liquid to rise in the center during rotation. The core area forms a higher accumulation phenomenon. At the same time, with the guiding effect of the annular baffle 71, the impurities can move more easily along the surface of the annular baffle 71 to the bottom of the plate. This makes it easier for the impurity particles in the cleaning liquid to accumulate at the bottom of the device. When the cleaning liquid stops rotating, the obstruction effect of the annular baffle 71 changes the return path of the impurities, requiring them to overcome gravity and climb over the inclined annular baffle 71. This increases the difficulty of impurity return and makes the impurities in the liquid accumulate more smoothly at the bottom of the device, and then be discharged to the outside of the device in one go during the subsequent wastewater discharge process.

[0028] Working principle: According to Figures 1 to 6, the gear shaft to be cleaned is first placed into the device. The gear shaft is placed vertically downwards into the corresponding mesh cylinder 62. Then, the cover 64 is screwed onto the outside of the threaded mounting ring 63. During tightening, the contact block 68 contacts the gear shaft. The contact block 68 is automatically moved upwards by the pressure of the gear shaft, simultaneously driving the limiting piston rod 66 to slide inside the limiting cylinder 65. At this time, the damping fluid inside the limiting cylinder 65 is controlled by the pressure of the limiting piston rod 66. The pressure action moves from one side of the piston disc through the through hole to the other side of the piston disc, and in this process, it plays a role in decelerating and protecting the limiting piston rod 66. At this time, the resisting spring 67 is in a contracted state due to the squeezing action of the limiting piston rod 66. At the same time, the squeezing force of the resisting spring 67 will also generate a reaction force and push the limiting piston rod 66 downward. When the limiting piston rod 66 moves downward, it will automatically drive the resisting block 68 to move and make it tightly abut against the upper end of the gear shaft. In this working process, the gear shaft is stably limited inside the mesh cylinder 62.

[0029] After all the gear shafts are in place, simply screw the protective cover 3 onto the top of the upper bucket 1. The specific threaded installation structure is similar to the existing cleaning bucket structure and will not be described in detail here.

[0030] Then, an appropriate amount of cleaning solution is poured into the interior of the upper tank 1 and the lower tank 2 through the inlet pipe at the top of the upper tank 1, ensuring the liquid level at least submerges the gear shaft. The drive motor 52 is then turned on. When the drive motor 52 is turned on, it automatically drives the drive gear 53 to rotate, which in turn drives the driven gear 54 to rotate. The rotation of the driven gear 54 then automatically drives the support shaft 55 to rotate, thereby causing multiple sets of gear shafts positioned on its outer side to rotate. When the support shaft 55 rotates, it also drives the auxiliary mounting plate 69 to rotate, simultaneously driving multiple sets of scrapers 610 to rotate. As the scrapers 610 rotate, they automatically scrape and clean the inner side wall of the upper tank 1, while simultaneously rotating the cleaning solution inside the device and cleaning the gear shaft. When the cleaning solution inside the device rotates, it is simultaneously subjected to... Due to the influence of centrifugal force, during rotation, the liquid particles move towards the outer edge, while the surface tension and gravity cause the liquid to rise in the center. This competitive effect leads to a higher accumulation of liquid in the center during rotation. At the same time, the guiding effect of the annular baffle 71 allows impurities to move more easily along the surface of the annular baffle 71 to the bottom of the plate, making it easier for impurity particles in the cleaning liquid to accumulate at the bottom of the device. When the cleaning liquid stops rotating, the obstruction effect of the annular baffle 71 changes the return path of the impurities, requiring them to overcome gravity and climb over the inclined annular baffle 71. This increases the difficulty of impurity return and makes it easier for impurities in the liquid to accumulate at the bottom of the device.

[0031] After the gear shaft is cleaned, the control valve 73 outside the drain pipe 72 is opened to remove the impurities in the device at once. Then, the protective cover 3 is unscrewed from the top of the upper barrel 1. The three sets of scrapers 610 can also be used as supports to support the protective cover 3 and the cleaning control components separately, so as to facilitate the subsequent dewatering process of the gear shaft. The material handling principle is the same as above.

[0032] According to GB / T 17494-1998 standard, the national standard model of drive gear 53 is 4M / 50 tooth spur gear, and the national standard model of driven gear 54 is 6M / 50 tooth spur gear. At the same time, the gear shaft to be cleaned must also meet the GB / T 17494-1998 standard.

[0033] In this device, the drive motor 52 is connected to an external power source via a power cord to start, which is a known and existing technology on the market and will not be described in detail here. The above is the working process of the entire device, and the contents not described in detail in this specification are all existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
