Description

Technical Field

[0001] This utility model belongs to the field of compressor steel sleeve cleaning devices, and in particular relates to a cleaning device for the inner ring of a machined compressor steel sleeve. Background Technology

[0002] During the machining of compressor steel sleeves, spiral iron filings and oil stains are easily left behind. Furthermore, the metal powder generated during high-temperature machining easily adheres to the coolant, forming hard deposits. Traditional cleaning methods often employ mechanical cleaning, but these only remove dirt from the outer surface of the steel sleeve and are insufficient to clean the iron filings and oil stains remaining on the inner ring. To clean the inner ring, manual washing is often used, but this traditional method is inefficient, has limited cleaning power, and cannot remove stubborn oil stains. The metal powder and oil stains generated in industrial production are often harmful to human health, and the burrs and sharp edges of the steel sleeve can also scratch the body. Therefore, manual cleaning of the inner ring of the machined compressor steel sleeve is inefficient. Utility Model Content

The upper end of the first slider 24 is connected to the movable end of the first linear module 25, and the fixed end of the first linear module 25 is installed on the inner wall of the frame 1. The waterproof plate 21 can block splashing water when the inner wall of the steel sleeve 6 is cleaned with water, maintain the sealing of the overall mechanical structure, keep the internal mechanical structure of the clamps 23 dry and clean, prevent corrosion, and extend the service life of the device.

[0038] like Figure 3As shown, the clamp 23 includes a second slider 231, a clamping plate 232, a first support rod 233, a connecting piece 234, a second support rod 235, and a third support rod 236. The second slider 231 is slidably connected to the periphery of the slide rail 22 on one side. The clamping plate 232 is disposed on the other side of the second slider 231. The connecting piece 234 is rotatably connected to the inner wall of the frame 1 through the first support rod 233. The upper end of the second slider 231 is hinged to one end of the connecting piece 234 through the second support rod 235. The other end of the connecting piece 234 is hinged to the lower end of the first slider 24 through the third support rod 236.

[0039] like Figure 4 As shown, the lower end of the first slider 24 is provided with two first square grooves 241, and a third support rod 236 is slidably connected in each first square groove 241. The outer periphery of the third support rod 236 abuts against the left and right sides inside the first square groove 241.

The outer periphery of the second support rod 235 abuts against the upper and lower ends in the second square groove 2311. The width of the second square groove 2311 is not less than the outer diameter of the second support rod 235, and the length of the second square groove 2311 is greater than the outer diameter of the second support rod 235. The second support rod 235 can slide left and right relative to the second square groove 2311 to adapt to the arc movement trajectory of the two ends when the connecting piece 234 rotates along the axis of the first support rod 233.

[0040] like Figure 5-7 As shown, the clamping assembly 2 also includes a metal rod 26 and a spring 27. The first end of the metal rod 26 is fixedly connected to a second slider 231. The second slider 231 has a circular hole, and the second end of the metal rod 26 is slidably connected in the circular hole. The spring 27 is sleeved around the metal rod 26, and the two ends of the spring 27 abut against the second slider 231 respectively. The clamping plate 232 has an arc-shaped groove, which is used to abut against the outer periphery of the steel sleeve 6.

[0041] The first linear module 25 comprises a telescopic cylinder, a linear motor, a lead screw, and other structures. In this embodiment, the first linear module 25 is a telescopic cylinder, which is existing technology. The model of the telescopic cylinder is Kuangxin BMSAI. When the steel sleeve 6 is placed in the drain trough 5 and needs to be fixed in position, the controller is turned on. The controller controls the movement of the movable end of the telescopic cylinder and pulls the first slider 24 along the slide groove. At the same time, it drives the connecting piece 234, which is hinged at the lower end, to rotate on the second support rod 235. The connecting piece 234 drives the two second sliders 231 to move along the slide rail 22 and move towards each other, thereby bringing the two clamping plates 232 closer together and clamping the outer periphery of the steel sleeve 6 through the arc groove. A clamping component 2 is provided, which can clamp and fix the position after the steel sleeve 6 is placed, facilitating subsequent cleaning steps. It can also adapt to steel sleeves 6 of different sizes, avoiding repeated component replacement, ensuring smooth cleaning, and improving efficiency.

[0042] like Figure 8 As shown, the cleaning assembly 3 includes two sets of second linear modules 31, a third slider 32, a servo motor 33, a synchronous pulley 34, a synchronous belt 35, a sleeve 36, and a brush 37. The two sets of second linear modules 31 are axially symmetrically arranged on both sides of the frame 1. The third slider 32 is slidably connected between the second linear modules 31. The outer periphery of the sleeve 36 is rotatably connected to the third slider 32. The lower end of the sleeve 36 is threadedly connected to the brush 37. The upper end of the sleeve 36 is fixedly connected to the synchronous pulley 34. The synchronous pulley 34 and the output shaft of the servo motor 33 form a synchronous transmission structure through the synchronous belt 35.

[0043] The second linear module 31 uses existing telescopic cylinders, linear motors, lead screws, and other structures. In this embodiment, the second linear module 31 is a lead screw structure. The servo motor 33 is a Mini Motor DBS55 / 100, which is an existing technology servo motor. After the steel sleeve 6 is fixed, the controller controls the lead screw to rotate and drives the third slider 32 to move, extending the brush 37 into the inner ring of the steel sleeve 6. After insertion, the controller controls the output shaft of the servo motor 33 to rotate, and drives the synchronous pulley 34 to rotate through the synchronous belt 35, which in turn drives the sleeve 36 to rotate inside the third slider 32, allowing the brush 37 to rotate in the inner ring of the steel sleeve 6 to achieve the purpose of cleaning the inner ring of the steel sleeve 6. While cleaning, the lead screw will also continuously change the direction of rotation to drive the third slider 32 to move up and down, and drive the brush 37 not only to rotate in the inner ring of the steel sleeve 6, but also to move up and down reciprocally to achieve the purpose of cleaning the inner ring of the steel sleeve 6. The cleaning component 3 is equipped to remove residual spiral iron filings and oil mixture from the inner ring of the steel sleeve 6, replacing traditional manual cleaning, improving cleaning efficiency, saving costs, and solving the problems of low efficiency and potential injury to the human body when manually cleaning the inner ring of the machined compressor steel sleeve.

[0044] like Figure 9As shown, the spray assembly 4 includes a bracket 41, a water pipe 42, a spray head 43, and a switch 44. The switch 44 is existing technology, model QMB5. The water pipe 42 is fixed to either side of the drain trough 5 via the bracket 41. One end of the water pipe 42 is connected to a water source, and the other end is connected to the spray head 43. The switch 44 is located in the middle of the water pipe 42. The water pipe 42 has a serpentine structure and rigid support, which can adjust and fix the position of the spray head 43. The spray assembly 4, which allows for angle adjustment, sprays water or cleaning fluid during the cleaning of the inner ring of the steel sleeve 6, rinsing the inside of the steel sleeve 6, dissolving some of the oil stains, and enhancing the cleaning effect.

[0045] like Figure 1 As shown, the drain trough 5 is equipped with multiple drain holes, which connect to the wastewater collection device below. The drain trough 5 with multiple drain holes allows the washed wastewater to be transferred to the wastewater collection device, preventing wastewater overflow and environmental pollution.

[0046] Working process of the inner ring cleaning device for turning compressor steel sleeve:

[0047] The outer periphery of the steel sleeve 6 is placed inside the two clamping plates 232, and the lower end of the steel sleeve 6 is placed in the drain trough 5. The controller is turned on, and the controller first controls the movement of the first linear module to bring the two clamping plates 232 closer together and use the arc groove to abut against the outer periphery of the steel sleeve 6. After clamping, the water pipe 42 is bent, and the spray head 43 is aligned with the inner ring of the steel sleeve 6. The switch 44 is turned on, and water flows out from the spray head 43 and enters the inner ring of the steel sleeve 6. At this time, the controller controls the second linear module 31 to move up and down reciprocally, and also controls the servo motor 33 to rotate, so as to achieve the purpose of cleaning the inner ring of the steel sleeve of the turning compressor.

[0048] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
