Description

Technical Field

[0001] This utility model belongs to the field of tapered sleeve processing technology, and in particular relates to a tapered sleeve pretreatment and cleaning machine. Background Technology

[0002] A tapered sleeve is a mechanical connecting part, shaped like a cone, used to connect components such as shafts and hubs, providing a reliable connection through the fit of the tapered surfaces. In industries such as steel rolling and machinery manufacturing, tapered sleeves accumulate oil, rust, and rolling residue over long-term use. If not thoroughly cleaned, this can lead to excessive pressure during assembly, causing damage to the tapered sleeve; reduced contact area, decreased transmission efficiency, and even slippage of the roller ring.

[0003] However, in the existing conical sleeve cleaning process, due to the diverse diameter specifications of the conical sleeve to be cleaned, the cleaning area on the outer surface of the conical sleeve shifts with the change in diameter; but when the existing cleaning mechanism performs cleaning operations on the outer surface of the conical sleeve, it cannot adaptively adjust the cleaning position on the outer surface of the conical sleeve according to the actual diameter of the conical sleeve.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] The technical solution of the conical sleeve pretreatment cleaning machine provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Reference Figures 1 to 10 As shown, this utility model embodiment provides a conical sleeve pretreatment cleaning machine, including a cleaning table 1, a protective cover 11 at the bottom of the cleaning table 1, and two hinged doors 12 on the protective cover 11; the cleaning table 1 is provided with a material handling assembly 2 for transporting conical sleeves and a conical sleeve cleaning assembly 3 for cleaning conical sleeves; the cleaning table 1 is provided with a groove 13, a horizontally arranged filter screen 14 is provided in the groove 13, a conical sleeve fixing assembly 4 is provided on the filter screen 14, a cleaning and recycling assembly 5 is provided in the groove 13 below the filter screen 14, and a conical sleeve placement platform 6 is provided on one side of the material handling assembly 2.

[0019] The core operation process of this cone sleeve pretreatment cleaning machine is as follows: the cone sleeve to be cleaned is first placed on the cone sleeve placement platform 6, and the material handling component 2 moves the cone sleeve to the cone sleeve fixing component 4 in the groove 13 of the cleaning table 1. After the cone sleeve fixing component 4 is adapted to the cone sleeve diameter and securely clamps it, the cone sleeve cleaning component 3 adjusts the cleaning position according to the actual diameter of the cone sleeve to precisely clean the outer surface and cone surface of the cone sleeve. The waste liquid generated during the cleaning process is initially filtered by the filter screen 14 and falls into the bottom of the groove 13, where it is filtered, recovered and circulated by the cleaning and recycling component 5. After cleaning, the material handling assembly 2 removes the cleaned cone sleeve. The entire process can be operated and maintained through the hinged door 12 of the protective cover 11. The protective cover 11 also prevents cleaning fluid from splashing and impurities from overflowing.

[0020] In this embodiment, the material handling assembly 2 includes a three-axis handling robot 21 and an electromagnetic adsorption plate 22. The three-axis handling robot 21 is located on the cleaning table 1, and the electromagnetic adsorption plate 22 is located on the three-axis handling robot 21.

[0021] After the conical sleeve to be cleaned is placed on the conical sleeve placement platform 6, the three-axis handling robot 21 moves the electromagnetic adsorption plate 22 to above the conical sleeve. The electromagnetic adsorption plate 22 is energized to generate magnetic force to adsorb the conical sleeve. Then, the three-axis handling robot 21 moves the conical sleeve to the fixed frame 43 of the conical sleeve fixing assembly 4. After cleaning, the robot moves the adsorption plate to the designated area again, and the power is turned off to release the conical sleeve, completing the material handling. The three-axis handling robot 21 has high positioning accuracy and can be adapted to gripping and transferring cone sleeves of different diameters, ensuring that the cone sleeve is accurately placed in the center of the fixed component, laying the foundation for subsequent precise cleaning.

[0022] In this embodiment, the conical sleeve fixing assembly 4 includes a fixing box 41, a fixing motor 42, a fixing platform 43, a first gear 44, three fixing arms 45, and three second gears 46. The fixing box 41 is located on top of the filter screen 14, and the fixing platform 43 is horizontally arranged on the fixing box 41. The fixing motor 42 is located inside the fixing box 41 and at the bottom of the fixing platform 43. The three fixing arms 45 are rotatably connected to the fixing platform 43 through three rotating shafts 47. The three second gears 46 are respectively arranged on the three rotating shafts 47. The first gear 44 is located on the main shaft of the fixing motor 42 and meshes with the three second gears 46. The fixing arms 45 are provided with fixing wheels 48, and the fixing wheels 48 are provided with a plurality of fixing rods 49. The fixing platform 43 is provided with three fixing platforms 491 arranged at equal intervals.

[0023] The conical sleeve to be cleaned is transported by the three-axis handling robot 21 and placed on the three fixed platforms 491 of the fixed frame 43. The fixed motor 42 starts and drives the first gear 44 on the main shaft to rotate. The first gear 44 meshes with the three second gears 46 to drive the three rotating shafts 47 to rotate synchronously, thereby driving the three fixed arms 45 to open outward from the fixed frame 43. The fixed wheels 48 on the fixed arms 45 are in contact with the inner wall of the conical sleeve, and the fixed rods 49 on the fixed wheels 48 are embedded in the fitting position of the conical sleeve, thus achieving coaxial fixation of conical sleeves of different diameters. For conical sleeves of different diameters, the fixed motor 42 can adjust the opening range of the fixed arms 45 by controlling the rotation angle to adapt to the fixation of different conical sleeve sizes.

[0024] The three fixed arms are evenly spaced and synchronously close / open through gear transmission. They can be used to securely clamp conical sleeves of different diameters, solving the problem that traditional fixing structures can only fix conical sleeves of a single specification. The inner wall of the cone sleeve is extended and fixed outward by the fixing rod 49, so that when the central cleaning brush roller 36 rotates to clean the inner wall of the cone sleeve, the central cleaning brush roller 36 can clean the contact clamping area, ensuring the thoroughness of the cleaning.

[0025] In this embodiment, the conical sleeve cleaning assembly 3 includes an automatic rotating arm 31, a lifting electric cylinder 32, a mounting frame 33, and a fixing plate 34. The automatic rotating arm 31 is mounted on the cleaning table 1, the lifting electric cylinder 32 is vertically mounted on the automatic rotating arm 31, the mounting frame 33 is connected to the telescopic end of the lifting electric cylinder 32, and the fixing plate 34 is connected to the bottom of the mounting frame 33.

[0026] In this embodiment, the conical sleeve cleaning assembly 3 further includes a first motor 35, a central cleaning brush roller 36, a second motor 37, a side cleaning brush roller 38, a rotating disk 39, and a rotating gear 391. The first motor 35 is located on the top of the fixed disk 34. The central cleaning brush roller 36 is connected to the main shaft of the first motor 35. The rotating disk 39 is provided with a rotating ring 392, and the rotating disk 39 is rotatably connected to the fixed disk 34 through the rotating ring 392. The rotating ring 392 is provided with a rotating gear ring 393. The second motor 37 is located on the top of the fixed disk 34. The rotating gear 391 is connected to the main shaft of the second motor 37, and the rotating gear 391 meshes with the rotating gear ring 393. The rotating disk 39 is provided with an adjusting component.

[0027] In this embodiment, the adjusting component includes an adjusting frame 30 horizontally disposed at the bottom of the rotating disk 39. The adjusting frame 30 is rotatably engaged with the bottom of the fixed disk 34. The adjusting frame 30 is provided with an adjusting screw 301 rotatably connected to it. The adjusting screw 301 is provided with an adjusting block 302 threadedly engaged with it. The adjusting block 302 is slidably engaged with the adjusting frame 30. The side cleaning brush roller 38 is rotatably connected to the adjusting block 302.

[0028] In this embodiment, both the central cleaning brush roller 36 and the side cleaning brush roller 38 are provided with water outlet holes 394.

[0029] An automatic rotating arm 31 is installed at a preset position on the cleaning table 1. It can drive the lifting electric cylinder 32 and subsequent cleaning components to rotate around the cone sleeve axis to the top of the cone sleeve. The lifting electric cylinder 32 drives the mounting frame 33 and the fixed plate 34 to move up and down, adjusting the contact distance between the central cleaning brush roller 36 and the side cleaning brush roller 38 and the surface of the cone sleeve. The first motor 35 drives the central cleaning brush roller 36 to rotate, cleaning the outer surface of the central area of ​​the cone sleeve. The second motor 37 drives the rotating gear 391 to rotate. The rotating gear 391 meshes with the rotating toothed ring 393 on the rotating ring 392, driving the rotating plate 39 to rotate around the fixed plate 34, thereby driving the side cleaning brush roller 38 to rotate around the cone sleeve circumferentially, realizing all-round cleaning of the outer surface of the cone sleeve.

[0030] When cleaning conical sleeves of different diameters, when the adjusting screw 301 is rotated, the adjusting block 302 slides along the adjusting frame 30, thereby driving the side cleaning brush roller 38 to move radially. For conical sleeves of different diameters, the distance between the side cleaning brush roller 38 and the center cleaning brush roller 36 is adjusted by rotating the adjusting screw 301, so that the side cleaning brush roller 38 accurately fits the cleaning action area on the outer surface of the conical sleeve, adapting to the cleaning position requirements of conical sleeves of different diameters. The adjusting component adjusts the radial position of the side cleaning brush roller 38 by adjusting the screw 301, which can accurately adapt to the outer surface cleaning area of ​​the conical sleeve with different diameters, ensuring that the cleaning brush roller and the outer surface of the conical sleeve are fully in contact, with no cleaning blind spots. The automatic rotating arm 31 drives the conical sleeve cleaning assembly 3 to rotate around the conical sleeve, and the lifting electric cylinder 32 adjusts the cleaning height. Combined with the center + side double brush roller structure, it realizes all-round cleaning of the outer surface and conical surface of the conical sleeve. The central cleaning brush roller 36 and the side cleaning brush roller 38 are driven independently, and the speed can be adjusted according to the degree of contamination of the cone sleeve to adapt to the cleaning needs of different types of dirt and improve the cleaning effect.

[0031] In this embodiment, the cleaning and recycling assembly 5 includes a recycling tank 51 disposed within the groove 13. The recycling tank 51 contains a filter 52, and a recycling pump 53 is connected to the side of the recycling tank 51. The recycling pump 53 is in fluid communication with the central cleaning brush roller 36 and the side cleaning brush roller 38 via a water outlet pipe 54, and is used to supply cleaning fluid to the water outlet 394. The water outlet pipe 54 is a corrugated flexible hose, which can move with the movement of the central cleaning brush roller 36 and the side cleaning brush roller 38.

[0032] The recycling bin 51 is installed below the filter screen 14 in the groove 13 of the cleaning table 1. The waste liquid generated during the cleaning process falls into the recycling bin 51 after being filtered by the filter screen 14 to remove large particles of impurities. The filter 52 in the recycling bin 51 further filters out small impurities such as iron filings and oil particles in the waste liquid. The recycling pump 53 draws the filtered cleaning liquid and delivers it to the water outlet 394 of the central cleaning brush roller 36 and the side cleaning brush roller 38 through the water outlet pipe 54. The cleaning liquid is sprayed out from the water outlet 394 and works with the central cleaning brush roller 36 and the side cleaning brush roller 38 to rinse the surface of the cone sleeve, so as to realize the recycling of the cleaning liquid. The cleaning fluid is recycled and reused, which greatly reduces the consumption of cleaning fluid and reduces waste discharge, meeting the requirements of green and environmentally friendly production. The double-layer filtration system with 14 filter screens and 51 recycling bins and 52 built-in filters effectively removes impurities in the cleaning fluid, preventing impurities from coming into contact with the cone sleeve again with the cleaning fluid and causing secondary pollution, thus improving the cleaning quality.

[0033] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
