Description

Technical Field

[0001] This utility model relates to the technical field of parts cleaning devices, and in particular to a parts cleaning device for mechanical control engineering. Background Technology

[0002] In the manufacturing and routine maintenance processes of mechanical control engineering, parts often accumulate contaminants such as cutting fluid, oil, and metal shavings on their surfaces after production, assembly, or use. To ensure the accuracy of subsequent processes and the reliability of equipment operation, effective cleaning is necessary. As a mainstream cleaning method, spray cleaning devices rely on high-speed flowing cleaning fluid to impact and dissolve the surface of parts, thereby achieving the purpose of removing contaminants.

[0003] However, many companies still use traditional, fixed spray cleaning equipment with simple structures. This type of equipment typically only has spray heads on the top or a few sides of the cleaning chamber, and the parts remain stationary during cleaning. This limits the spray angle and coverage of the high-pressure water jet, making it difficult to achieve uniform rinsing of the entire surface of the parts. To compensate for cleaning blind spots, on-site operators often need to interrupt the cleaning process to manually flip, move, or rearrange the parts to improve the cleaning effect. This not only reduces work efficiency but also increases labor intensity. Alternatively, manual cleaning using handheld spray guns requires constant adjustment of the spray angle and flipping of parts, resulting in low cleaning efficiency and being time-consuming and labor-intensive.

[0004] Therefore, this application provides a parts cleaning device for mechanical control engineering to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a parts cleaning device for mechanical control engineering, which solves the problems of traditional fixed spray cleaning, such as many blind spots, need for manual intervention to turn over, low efficiency and high labor intensity caused by the static nature of the parts and the limited spray angle.

[0007] A further improvement of this utility model is that the U-shaped pipe also includes a vertical pipe, the upper and lower ends of which are connected to the horizontal upper and lower support arms, respectively. Several spray balls are evenly arranged along the length of the vertical pipe, the upper support arm, and the lower support arm. A stainless steel pipe seat is connected to the bottom end of the vertical pipe. The stainless steel pipe seat is centrally connected and embedded in the corner of the base plate and communicates with the inner cavity of the vertical pipe. The stainless steel pipe seat is connected to the external water supply system through the water inlet pipe.

[0008] A further improvement of the present invention is that the base plate includes an integrally formed inclined plate and a horizontal plate; the inclined plate extends upward from the point where it connects with the horizontal plate at an angle of 5 to 20 degrees.

[0009] A further improvement of this utility model is that: a water outlet is provided in the middle of the horizontal plate, and a flange bend is sealed and fixed at the lower end of the water outlet; an upwardly protruding groove is formed in the middle area of ​​the inclined plate, with the groove opening facing upward and the top of the groove remaining horizontal.

[0010] A further improvement of the present invention is that the cleaning chamber also includes four vertical side plates, each of which is sealed to the four sides of the bottom plate to form a rectangular cleaning chamber with an opening at the top.

[0011] A further improvement of this utility model is that: the inner walls of the four side plates are provided with horizontal supports, the top of the supports are provided with cylinders, and waterproof bearings are fitted on the cylinders. The outer circumference of the waterproof bearings rolls in contact with the bottom surface of the ring of the ring-shaped placement frame to form auxiliary support.

[0012] A further improvement of this utility model is that: a support frame is provided in the middle of the support plate, and a reducer is fixedly installed on the support frame; a motor is provided on one side of the support frame on the support plate, and a double-row sprocket A is installed on the output shaft of the motor. The double-row sprocket A is connected to the double-row sprocket B through a chain, and the double-row sprocket B is installed on the drive shaft of the reducer.

[0013] A further improvement of this utility model is that: a flanged short pipe is provided on the top surface of the support frame, a single flange pipe is provided on the top of the flanged short pipe, the flanged short pipe and the single flange pipe are connected at their flange parts by bolts, the pipe body of the single flange pipe extends upward through the top of the trench, and the top surface of the flange of the single flange pipe is in contact with the bottom surface of the top of the trench.

[0015] A further improvement of the present invention is that the ring-shaped placement frame includes a disc, support rods, and a ring body; the disc is fixed to the top of the extension shaft; multiple support rods are evenly distributed radially, with their inner ends fixed to the outer periphery of the disc and their outer ends extending to the ring body and fixedly connected thereto, forming a support structure radiating outward from the center of the circle, with the bottom surface of the support rods flush with the disc and the top surface higher than the disc.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects: 1. This utility model provides a parts cleaning device for mechanical control engineering. This device, through a rotatable annular placement frame and U-shaped spray pipes arranged around it, effectively solves the problem of dead angles that are common in traditional spray cleaning methods. Specifically, the upper and lower branches of the U-shaped pipes extend above and below the annular placement frame, respectively, while the vertical pipes are close to the lateral space. The three pipe sections are densely arranged with spray balls along the length direction, creating a three-dimensional, fully covered spray field around the parts. When the reducer drives the annular placement frame to rotate the parts at a uniform speed, the spray balls continuously output high-pressure cleaning fluid from multiple dimensions, including up, down, left, right, front, and back, so that the surface of the parts is subjected to equivalent impact at any angle, achieving 360° dynamic circumferential cleaning; improving the overall cleanliness and uniformity of the parts, reducing labor intensity, and increasing cleaning efficiency.

[0017] 2. This utility model provides a parts cleaning device for mechanical control engineering. This device achieves efficient automatic wastewater discharge by integrating a sloped bottom plate with a horizontal plate for collecting wastewater. The wastewater, guided by the slope, quickly collects at the outlet in the middle of the horizontal plate and is discharged through a flange bend, effectively preventing impurities from settling and cleaning fluid residue. Simultaneously, grooves punched into the slope provide embedded installation space for components such as drive shaft bearings. While ensuring unobstructed drainage, this device improves structural compactness and sealing performance. Compared to traditional flat-bottom structures, it significantly reduces liquid retention and maintenance frequency, thereby increasing cleaning efficiency.

[0018] 3. This utility model provides a parts cleaning device for mechanical control engineering. This cleaning device improves the cleaning effect of parts through the design of a ring-shaped placement rack structure. The placement rack consists of a central disc, an outer ring, and multiple radially distributed support rods connecting the two. The top surface of the support rods is higher than the top surface of the disc, forming slightly raised ribs. This effectively reduces the contact area between the parts and the placement rack, maximizing the exposure of the bottom surface of the parts, facilitating thorough impact of the cleaning fluid, and promoting wastewater discharge, ensuring thorough cleaning and efficient draining.

[0019] 4. The present invention provides a parts cleaning device for mechanical control engineering. The cleaning device has a bracket set on the inner wall of the side plate. The bracket forms a rolling auxiliary support for the ring of the ring placement frame through a cylinder and a waterproof bearing, thereby realizing radial limiting and axial support for rotating parts, effectively suppressing the sway and vibration caused by high-speed rotation, and ensuring the stability of the cleaning process.

[0026] The present invention will be further explained below with reference to specific embodiments.

[0027] like Figure 1-12As shown in the figure, this embodiment provides a parts cleaning device for mechanical control engineering, including a housing 1. The top of the housing 1 can be hinged to a cover (not shown in the figure). A cleaning chamber 2 is provided on the upper part of the housing 1, and a reducer 4 is installed below the cleaning chamber 2 via a support plate 3. The output shaft of the reducer 4 passes vertically upward through the bottom plate 21 of the cleaning chamber 2, and its extended end is coaxially fixedly mounted with an annular placement frame 5. The annular placement frame 5 is specifically used to carry the parts 6 to be cleaned. Its annular structure allows the surface of the parts to be fully exposed when rotating, improving cleaning efficiency. At least two U-shaped tubes 7, preferably two, are arranged symmetrically around the rotation axis of the annular placement frame 5 inside the cleaning chamber 2. This ensures that the parts 6 to be cleaned can be covered by spray balls 74 above, below, and to the sides, while leaving sufficient loading and unloading space so that the operator can quickly put or take out the parts 6 to be cleaned into or out of the annular placement frame 5 from between the two tubes. The opening of the U-shaped tube 7 faces the annular placement frame 5, so that its upper support arm 71 and lower support arm 72 extend to the upper and lower parts of the annular placement frame 5, respectively, thereby covering the upper and lower areas of the parts. Several spray balls 74 are installed inside the U-shaped tube 7. The spray balls 74 spray cleaning liquid at multiple angles through the internal channels. When the annular placement frame 5 rotates under the drive of the reducer 4, the spray balls 74 simultaneously rinse the parts 6 to be cleaned from multiple directions in an all-round manner, so as to achieve efficient cleaning.

[0028] like Figure 2 , Figure 3 , Figure 5 As shown, in this embodiment, the U-shaped pipe 7 also includes a vertical pipe 73. The upper and lower ends of the vertical pipe 73 are connected to the horizontal upper support arm 71 and lower support arm 72, respectively. A plurality of spray balls 74 are evenly arranged along the length of the vertical pipe 73, the upper support arm 71, and the lower support arm 72. A stainless steel pipe seat 75 is connected to the bottom end of the vertical pipe 73. The stainless steel pipe seat 75 is centrally penetrated and embedded in the corner of the base plate 21, and communicates with the inner cavity of the vertical pipe 73. The stainless steel pipe seat 75 extends out of the shell 1 through the water inlet pipe 23 and is connected to the external water supply system. The U-shaped pipe 7 is made entirely of stainless steel. The spray balls 74 are existing equipment. The spray balls 74 can be connected to the vertical pipe 73, the upper support arm 71, and the lower support arm 72 by means of threaded connection, welding, etc.

[0029] like Figure 4 , Figure 6 , Figure 7As shown, in this embodiment, the base plate 21 includes an integrally formed inclined plate 211 and a horizontal plate 212; the inclined plate 211 extends upward at an angle of 5 to 20 degrees from the point where it connects with the horizontal plate 212. This inclined surface can guide the wastewater and impurities after cleaning to flow naturally to the outlet hole 213, reducing residue. The horizontal plate 212 has an outlet hole 213 in the middle, and the lower end of the outlet hole 213 is sealed and fixed to a flange bend 22; the flange bend 22 extends out of the shell 1, directly guiding the centrally discharged sewage into the external recycling system, achieving no liquid accumulation and no residue in the chamber. The middle area of ​​the inclined plate 211 is stamped to form an upwardly protruding groove 214, the groove opening of the groove 214 faces upward and the groove top 215 remains horizontal, providing an accurate installation reference for the single flange pipe 312, facilitating the installation of the single flange pipe 312.

[0030] like Figure 2 , Figure 4 , Figure 8 As shown, in this embodiment, the cleaning chamber 2 also includes four vertical side plates 24. Each side plate 24 is sealed to the four sides of the base plate 21, forming a rectangular cleaning chamber 2 with an open top. Horizontal supports 25 are provided on the inner walls of each of the four side plates 24. A cylinder 251 is provided at the top of each support 25, and a waterproof bearing 252 is mounted on the cylinder 251. The outer circumferential surface of the waterproof bearing 252 rolls in contact with the bottom surface of the ring 53 of the annular placement frame 5, forming auxiliary support. By providing supports 25 with waterproof bearings 252 on the side plates 24, effective auxiliary support is provided for the annular placement frame 5, which not only enhances the equipment's load capacity and operational stability but also improves the device's adaptability to parts of different weights.

[0031] like Figure 10 , Figure 11 , Figure 12As shown, in this embodiment, a support frame 31 is provided in the middle of the support plate 3, and a reducer 4 is fixedly installed on the support frame 31. A motor 32 is provided on one side of the support frame 31 on the support plate 3. A double-row sprocket A33 is installed on the output shaft of the motor 32. The double-row sprocket A33 is connected to the double-row sprocket B35 through a chain 34. The double-row sprocket B35 is installed on the drive shaft of the reducer 4. A flanged short pipe 311 is provided on the top surface of the support frame 31. A single flange pipe 312 is provided on the top of the flanged short pipe 311. The flanged short pipe 311 and the single flange pipe 312 are connected at their flange positions by bolts. The pipe body of the single flange pipe 312 extends upward through the top of the groove 215, and the top surface of the flange of the single flange pipe 312 is in contact with the bottom surface of the top of the groove 215. An extension shaft 41 is fitted onto the output shaft of the reducer 4; the extension shaft 41 is coaxially inserted into the mounting cavity composed of the flange short pipe 311 and the single flange pipe 312, and its top end extends to the outside of the single flange pipe 312; a bearing A313 is embedded at the bottom of the inner cavity of the flange short pipe 311, and a bearing B314 is embedded at the top of the inner cavity of the single flange pipe 312; the extension shaft 41 is interference-fitted with the inner rings of the bearings A313 and B314 respectively; an annular mounting bracket 5 is fixedly connected to the top end of the extension shaft 41 to support and fix the annular mounting bracket 5. The annular placement rack 5 includes a disc 51, support rods 52, and a ring 53. The disc 51 is fixed to the top of the extension shaft 41. Multiple support rods 52 are evenly distributed radially, with their inner ends fixed to the outer periphery of the disc 51 and their outer ends extending to and fixedly connected to the ring 53, forming a support structure radiating outward from the center. The bottom surface of the support rods 52 is flush with the disc 51, and the top surface is 1-6 mm higher than the top surface of the disc 51, forming micro-convex ribs. This effectively reduces the contact area between the parts and the placement rack, maximizes the exposure of the bottom surface area of ​​the parts, facilitates the full impact of the cleaning fluid, and also facilitates the discharge of wastewater, ensuring thorough cleaning and efficient draining.

[0032] This embodiment provides the working principle of a parts cleaning device for mechanical control engineering: The parts 6 to be cleaned are placed from the top-opening cleaning chamber 2 onto the radial support rods 52 of the annular placement frame 5. The micro-protruding ribs between the disc 51 and the ring 53 reduce the contact area. The motor 32 is started, driving the reducer 4 via the double-row sprocket A33, chain 34, and double-row sprocket B35. The output shaft of the reducer 4 drives the extension shaft 41 to rotate under the double bearing support of the flange short pipe 311 and the single flange pipe 312, thereby driving the annular placement frame 5 to rotate at a uniform speed. The external water supply system is connected to the water inlet pipe 23. The stainless steel pipe seat 75 supplies liquid to the stainless steel U-shaped pipe 7. The cleaning liquid is sprayed out at high speed from multiple angles through the spray balls 74 densely distributed on the vertical pipe 73, the upper branch pipe arm 71, and the lower branch pipe arm 72, which rinse the rotating parts 6 to be cleaned from all directions. The wastewater after rinsing flows naturally along the inclined plate 211 of the bottom plate 21 to the water outlet 213 of the horizontal plate 212 and is discharged through the flange bend 22. The bracket 25 with waterproof bearing 252 on the inner wall of the side plate 24 continuously supports the ring body 53, ensuring that the high-speed rotation is stable and without shaking, thus completing the efficient, thorough, and low-residue parts cleaning operation.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
