Description

Technical Field

[0001] This utility model relates to the field of steel ball cleaning and processing, and in particular to a cleaning device for high-precision spherical parts. Background Technology

[0002] Bearing steel balls, also known as bearing steel balls, are core components that determine the lifespan and precision of bearings. After casting, they need to be cleaned to remove residual metal shavings, oil, or fibers from their surface. Currently, the cleaning method for bearing steel balls usually involves pouring the bearing into a cleaning chamber and cleaning it using high-pressure spraying combined with brushes or agitators. However, bearing steel balls are heavy and tend to settle and accumulate at the bottom, causing the steel balls in the central area to remain stuck together during cleaning. This creates dead zones that cannot be completely cleaned. At the same time, the mutual squeezing and friction of a large number of steel balls can easily cause minor damage to the surface of the bearing steel balls, reducing the bearing's vibration level. Utility Model Content

[0003] In view of the problems in the above or existing technologies, such as the high specific gravity of bearing steel balls, which makes them easy to settle and accumulate at the bottom, causing the bearing steel balls in the central area to remain stuck together during the cleaning process, resulting in dead corner areas that cannot be completely cleaned, and the large number of steel balls squeezing and rubbing against each other, which can easily cause slight damage to the surface of the bearing steel balls and reduce the vibration level of the bearing, this utility model is proposed.

[0004] Therefore, the purpose of this invention is to provide a cleaning device for high-precision spherical parts.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a spray unit, a movable support unit disposed on the spray unit, and a cleaning auxiliary unit disposed on the movable support unit.

[0006] As a preferred embodiment of the cleaning device for high-precision spherical parts of this utility model, the spray unit includes a cleaning chamber, an inlet pipe disposed on the cleaning chamber, a nozzle disposed on the top of the inner wall of the cleaning chamber and connected to the inlet pipe, and a drain pipe disposed at the bottom of the cleaning chamber.

[0007] As a preferred embodiment of the cleaning device for high-precision spherical parts of this utility model, the movable support unit includes a support seat disposed on one side of the cleaning chamber, a movable component disposed on the support seat, a mounting plate disposed on the movable component, and a stabilizing slide rod disposed on the mounting plate and slidably connected to the support seat.

[0008] As a preferred embodiment of the cleaning device for high-precision spherical parts of this utility model, the movable component includes a servo motor mounted on a support base, an output gear mounted on the output end of the servo motor, a connecting shaft mounted on the output gear, the connecting shaft not passing through the rotation axis of the output gear, a connecting rod rotatably connected at one end to the connecting shaft, and a connecting block mounted on a mounting plate, the other end of the connecting block and the connecting rod being rotatably connected.

[0009] As a preferred embodiment of the cleaning device for high-precision spherical parts of this utility model, the cleaning auxiliary unit includes a fixed plate disposed on the mounting plate, a lower bearing plate disposed on the fixed plate, and an upper bearing plate disposed on the lower bearing plate, wherein a partition component is disposed between the lower bearing plate and the upper bearing plate.

[0010] The cleaning chamber is equipped with an interface for fitting the fixing plate;

[0011] Multiple cleaning auxiliary units can be detachably installed on the mounting plate.

[0012] As a preferred embodiment of the cleaning device for high-precision spherical parts of this utility model, the lower support plate is provided with an insertion groove and a limiting slider.

[0013] The cleaning chamber is equipped with a sliding groove that matches the insertion slot;

[0014] The upper support plate is equipped with a plug-in block that works with the limit slider.

[0015] As a preferred embodiment of the cleaning device for high-precision spherical parts of this utility model, the separating component includes abutment holes disposed on the lower support plate and the upper support plate, a flexible friction material disposed on the side of the abutment hole that contacts the spherical part, a connecting groove disposed on the abutment hole, and a guide groove disposed on the abutment hole.

[0017] The beneficial effects of this high-precision spherical parts cleaning device are as follows: This device uses a movable component to drive the cleaning auxiliary unit to move back and forth on the cleaning chamber. A guide groove guides the spherical parts poured onto the lower support plate, causing them to sway back and forth into the contact holes. The contact holes on the upper support plate further divide the space between the lower and upper support plates into multiple small spaces. The spherical parts roll back and forth within these spaces, and the spray from the nozzles cleans them. Wastewater flows downwards through a connecting groove. This method separates the spherical parts for cleaning, and the rolling motion within the contact holes ensures a thorough cleaning of their surfaces, preventing accumulation and protecting them while providing comprehensive cleaning.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1-8 This is one embodiment of the present invention, which provides a cleaning device for high-precision spherical parts, including a spray unit 1 for cleaning spherical parts 4, a movable support unit 2 disposed on the spray unit 1 for supporting the spherical parts 4 and moving the spherical parts 4 within the spray unit 1 to assist in cleaning, and a cleaning auxiliary unit 3 disposed on the movable support unit 2 for supporting the spherical parts 4, separating the spherical parts 4 one by one so that the spherical parts 4 do not contact each other during cleaning, ensuring that each spherical part 4 is thoroughly cleaned.

[0030] The spray unit 1 includes a cleaning chamber 11 for cleaning the spherical part 4, an inlet pipe 12 installed on the cleaning chamber 11 for receiving cleaning fluid, a nozzle 13 installed on the top of the inner wall of the cleaning chamber 11 and connected to the inlet pipe 12 for spraying out cleaning fluid to cooperate with the movable support unit 2 and the cleaning auxiliary unit 3 to clean the spherical part 4, and a drain pipe 14 installed at the bottom of the cleaning chamber 11 for collecting cleaning wastewater.

[0031] The movable support unit 2 includes a support base 21 located on one side of the cleaning chamber 11, which serves to fix and support the unit. The bottom of the support base 21 is equipped with a pulley or slide rail with a locking function. This configuration allows the cleaning auxiliary unit 3 to be pulled out and inserted into the cleaning chamber 11 by moving the support base 21. The movable component 22 located on the support base 21 controls the back-and-forth movement of the cleaning auxiliary unit 3 in the cleaning chamber 11. The mounting plate 23 located on the movable component 22 connects the movable component 22 and the cleaning auxiliary unit 3. The stabilizing slide rod 24 located on the mounting plate 23 and slidably connected to the support base 21 limits the movement of the mounting plate 23, allowing the mounting plate 23 to slide back and forth linearly on the support base 21 in coordination with the drive of the movable component 22 via the stabilizing slide rod 24.

[0032] The active component 22 includes a servo motor 221 mounted on the support base 21 for generating power; an output gear 222 mounted on the output end of the servo motor 221 for rotating in coordination with the drive of the servo motor 221; a connecting shaft 223 mounted on the output gear 222, which does not pass through the rotation axis of the output gear 222 and is used to rotate eccentrically relative to the rotation axis of the output gear 222 in coordination with the rotation of the output gear 222; a connecting rod 224 rotatably connected at one end to the connecting shaft 223, which exerts a pushing and pulling effect on the connecting rod 224 through the eccentric rotation of the connecting shaft 223; and a connecting block 225 mounted on the mounting plate 23, which is rotatably connected to the other end of the connecting block 225. The connecting rod 224 drives the mounting plate 23 to reciprocate linearly on the support base 21 in coordination with the stabilizing slide bar 24 through the connecting block 225, thereby driving the cleaning auxiliary unit 3 to move back and forth in the cleaning chamber 11.

[0033] The cleaning auxiliary unit 3 includes a fixed plate 31 on the mounting plate 23 for connecting, a lower support plate 32 on the fixed plate 31 for supporting the spherical parts 4, and an upper support plate 33 on the lower support plate 32 for forming a space for the spherical parts 4 to move in conjunction with the lower support plate 32. A partition component 34 is provided between the lower support plate 32 and the upper support plate 33 to separate the spherical parts 4 on the lower support plate 32 one by one to prevent them from accumulating and colliding with each other during cleaning.

[0034] The cleaning chamber 11 is provided with an insertion interface 111 that matches the fixing plate 31, which is used to support the fixing plate 31.

[0035] Multiple sets of cleaning auxiliary units 3 can be detachably installed on the mounting plate 23. With this setting, the number of sets of cleaning auxiliary units 3 can be increased or decreased according to the number of spherical parts 4 to be cleaned.

[0036] The lower support plate 32 is provided with a plug groove 321 and a limiting slider 322. The plug groove 321 is used for limiting the sliding, and the limiting slider 322 is used to connect with the upper support plate 33.

[0037] The cleaning chamber 11 is provided with a sliding groove 112 that matches the insertion groove 321. The insertion groove 321 and the sliding groove 112 cooperate to make the lower support plate 32 drive the upper support plate 33 to slide back and forth on the cleaning chamber 11, causing the spherical part 4 to shake and causing the spherical part 4 to roll in the partition assembly 34 to cooperate with the liquid inlet pipe 12 for cleaning.

[0038] The upper support plate 33 is provided with a plug block 331 that cooperates with the limiting slider 322. The plug block 331 cooperates with the limiting slider 322 to drive the upper support plate 33 to connect with the lower support plate 32. A pin can be provided between the limiting slider 322 and the plug block 331 to enhance the stability of the connection between the limiting slider 322 and the plug block 331.

[0039] The separator 34 includes abutment holes 341 on the lower support plate 32 and the upper support plate 33 for supporting and abutting the spherical part 4. A flexible friction material is provided on the side of the abutment hole 341 that contacts the spherical part 4 to prevent scratches on the surface of the spherical part 4. At the same time, it works with the spraying of the nozzle 13 and the rolling motion of the lower support plate 32 to clean the spherical part 4. A connecting groove 342 is provided on the abutment hole 341 to provide a connection and prevent the spherical part 4 from blocking the abutment hole 341, which would prevent the cleaning fluid from flowing in and out. A guide groove 343 is provided on the abutment hole 341 to guide the spherical part 4 with the back and forth movement of the lower support plate 32, so that the spherical part 4 enters the connecting groove 342 as the lower support plate 32 moves back and forth, so that the connecting grooves 342 do not come into contact with each other during cleaning.

[0040] The diameter of the contact hole 341 is smaller than the diameter of the spherical part 4 to be cleaned. The distance between the two sets of corresponding contact holes 341 in the working state is smaller than the diameter of the spherical part 4 to be cleaned, but larger than the diameter of the contact hole 341. With this setting, the separator assembly 34 can stably support the spherical part 4, and at the same time, the spherical part 4 can roll on the contact hole 341 in coordination with the back and forth movement of the lower support plate 32, and clean it in coordination with the nozzle 13. When the lower support plate 32 and the upper support plate 33 are in a closed state, the two sets of contact holes 341 are connected by the connecting groove 342. With this setting, the cleaning fluid sprayed by the nozzle 13 can flow from the upper cleaning auxiliary unit 3 to the lower cleaning auxiliary unit 3. At the same time, this connected state prevents the cleaning fluid from remaining in the separator assembly 34, which facilitates drying.

[0041] In summary, when the spherical parts 4 need to be cleaned, the cleaning auxiliary unit 3 is pulled out of the cleaning chamber 11 via the support base 21. The upper support plate 33 is then opened from the lower support plate 32 via the plug-in block 331. The spherical parts 4, up to the maximum capacity of the lower support plate 32, are then poured onto it. The servo motor 221 is then activated, driving the movable component 22 to rotate. The output gear 222 rotates, generating a back-and-forth pushing and pulling force on the connecting rod 224 via the connecting shaft 223. At this time, the mounting plate 23 drives the fixing plate 31 to move back and forth on the support base 21 in conjunction with the pushing and pulling of the mounting plate 23 and the limiting of the stabilizing slide rod 24. At this time, the spherical parts 4 on the lower bearing plate 32 are rolled by the back and forth movement of the lower bearing plate 32. The spherical parts 4 roll back and forth on the lower bearing plate 32 and, with the guidance of the guide groove 343, enter the abutment hole 341. At this time, each spherical part 4 abuts against the corresponding abutment hole 341. At this time, the servo motor 221 is stopped, so that the lower bearing plate 32 stops moving. At this time, the upper support plate 33 is connected to the upper support plate 33 through the action of the plug block 331 and the limiting slider 322. At this time, the entire cleaning auxiliary unit 3 is inserted into the cleaning chamber 11 through the cooperation of the plug groove 321 and the sliding groove 112 via the support base 21. At this time, the nozzle 13 is started to spray cleaning liquid evenly into the cleaning chamber 11. At this time, the servo motor 221 is started, and the lower support plate 32 is driven to move back and forth in the cleaning chamber 11 through the mounting plate 23. At this time, the spherical part 4 is moved back and forth by the abutment hole 341. The spherical part 4 is subjected to force and tumbles up and down in the contact hole 341. At this time, the cleaning fluid enters between the lower support plate 32 and the upper support plate 33 through the contact hole 341 on the upper support plate 33 and comes into contact with the spherical part 4. The contact hole 341, together with the nozzle 13, cleans the tumbling spherical part 4. At this time, the cleaning fluid carries the impurities washed off the spherical part 4 and flows downward through the connecting groove 342, realizing the independent cleaning of the spherical part 4, avoiding the generation of cleaning dead corners, and at the same time protecting the spherical part 4.
