Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ultrasonic cleaning, and in particular to an ultrasonic cleaning device for tapered rollers. Background Technology
[0002] Tapered rollers are an important component of bearings. The production process of tapered rollers involves multiple steps, including hard grinding, spherical grinding, and ultra-precision grinding. During the processing, impurities such as iron filings and oil stains are inevitably present on the rollers. In order to improve the processing accuracy of the rollers, it is often necessary to clean them.
[0003] Although there are some roller cleaning devices on the market, most of them clean the rollers by rinsing or ultrasonic cleaning. During cleaning, tooling is required to clamp the rollers, resulting in a clamping and supporting contact area between the tooling and the rollers. Cleaning dead corners are easily created in the contact area, making it impossible to clean thoroughly and resulting in incomplete cleaning.
[0004] Therefore, this utility model provides a new technical solution to the problem of cleaning tapered rollers. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an ultrasonic cleaning device for tapered rollers, which has a simple structure and can comprehensively improve the cleaning quality and efficiency of tapered rollers.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An ultrasonic cleaning device for tapered rollers includes a frame, a lifting assembly, and a cleaning tray. A water tank is fixedly installed inside the frame, and the lifting assembly is partially placed in the water tank and fixedly installed on the frame by a fixing plate.
[0008] The lifting assembly also includes a telescopic rod, a support rod, and a support plate. The support rods are arranged side by side and a cleaning plate can be installed at the upper end. The support plate is movably installed below the support rods and can be adjusted in the vertical direction.
[0009] The telescopic rod is driven by a cylinder to move the cleaning disc up and down. During the descent, the cleaning disc has a first cleaning position and a second cleaning position.
[0010] The cleaning tray can hold several workpieces, and the cleaning trays can be stacked together. When the cleaning tray is in the first cleaning position, there is a gap between the upper end of the support plate and the bottom end of the workpiece. When it is in the second position, the upper end of the support plate abuts against the bottom end of the workpiece.
[0011] The present invention is further configured such that the fixing plate consists of two pieces, which are respectively fixedly installed on both sides of the upper end of the frame by bolts, and the support rod is located below the fixing plate and is fixedly connected to the telescopic rod by a connecting plate.
[0012] The present invention is further configured such that a cylinder is fixedly installed on the upper end of the fixed plate, and a connecting plate is fixedly connected to the lower end through a telescopic rod. Support rods are fixedly connected to both ends below the connecting plate. The telescopic rods are driven by the cylinders and can drive the support rods to move in the vertical direction.
[0013] The present invention is further configured such that a limiting rod is fixedly installed on both sides of the upper end of the connecting plate, the limiting rod extending upward through the fixed plate and slidingly connected with the fixed plate.
[0014] The present invention is further configured such that adjusting screws are fixedly connected to both ends of the support plate, the adjusting screws extend upward through the connecting plate and the fixed plate, and are locked to the fixed plate by adjusting nuts.
[0015] The present invention is further configured such that the support plate is slidably connected to limit rods two at the four corners, the limit rods two are arranged in the vertical direction, the lower end is fixedly connected to the bottom of the water tank, and the upper end extends upward and is slidably connected to the fixed plate. The support plate can be slidably adjusted in the vertical direction along the limit rods two by rotating the adjusting nut.
[0016] The present invention is further configured such that the two sides of the cleaning disc extend outward along the direction of the support rod to form a limiting part, the cleaning disc can be embedded between the two support rods, and the limiting part on both sides abuts against the upper end of the support rod for limiting.
[0017] The present invention is further configured such that the cleaning tray has a plurality of limiting holes inside, the workpiece has a first end and a second end, the first end of the workpiece passes through the limiting holes, and the outer periphery of the workpiece abuts against and limits the inner periphery of the limiting holes.
[0018] The present invention is further configured such that a stepped portion one is provided on the inner circumference of the cleaning tray near the upper end, and a stepped portion two is provided on the outer circumference of the cleaning tray near the bottom end, and the cleaning trays can be stacked and installed by the cooperation of the stepped portion one and the stepped portion two.
[0019] The present invention is further configured such that when the cleaning trays are stacked and in the first cleaning position, there is a gap between the first end of the workpiece and the upper end of the support plate; when in the second cleaning position, the first end of the workpiece abuts against the upper end of the support plate and pushes the lower workpieces to move upward as a whole, the second end of the lower workpiece abuts against and pushes the first end of the upper workpieces to move upward as a whole, and a gap is formed between the outer periphery of the workpiece and the inner periphery of the limiting hole.
[0020] The beneficial effects of this invention are as follows: Firstly, the device uses cleaning trays to load workpieces in batches for cleaning. The cleaning trays can be stacked, allowing for simultaneous cleaning of large quantities of workpieces and improving cleaning efficiency. Secondly, the ultrasonic cleaning device has two cleaning processes. In the first cleaning, the cleaning trays are stacked and fully immersed in the cleaning solution. At this time, the workpieces in the upper and lower cleaning trays maintain an appropriate gap, cleaning the outer periphery of the workpieces. Because the workpieces are embedded in the limiting holes and press against the inner circumference of the limiting holes, a cleaning dead zone is formed at the contact point, making thorough cleaning impossible. Therefore, after the first cleaning is completed, the cleaning trays continue to descend, causing the first end of the workpiece in the bottom cleaning tray to abut against the support plate and move upwards relative to the cleaning tray. The bottom workpiece moves upwards and abuts against the upward movement of the upper workpiece, causing the workpieces to move upwards relative to the cleaning tray, maintaining an appropriate gap between the workpiece and the inner circumference of the limiting hole. Then, the second cleaning is performed, ensuring comprehensive cleaning of the workpieces and improving the surface cleaning quality. Attached Figure Description

Detailed Implementation
[0029] 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.
[0030] This embodiment discloses an ultrasonic cleaning device for tapered rollers, referring to... Figures 1-6 As shown, it mainly includes a frame 1, a lifting assembly 2, and a cleaning tray 3 for placing workpieces 4. A water tank 11 is fixedly installed inside the frame 1. The lifting assembly 2 is partially placed inside the water tank 11 and fixedly installed on the frame 1 by a fixing plate 21. An appropriate amount of cleaning liquid is poured into the water tank 11, and then an ultrasonic cleaner is installed inside the water tank 11. By controlling the lifting assembly 2, the cleaning tray 3 can be moved up and down, so that the workpieces 4 placed in the cleaning tray 3 can be completely immersed in the cleaning liquid for cleaning. The operation is convenient and can fully improve the cleaning efficiency and cleaning quality of the workpieces 4.
[0031] Reference Figure 2 As shown, the lifting assembly 2 mainly includes a fixed plate 21, a telescopic rod 25, support rods 24, and a support plate 23. Two fixed plates 21 are provided, arranged symmetrically, and are respectively fixed to both sides of the upper end of the frame 1 by bolts. Cylinders 29 are fixedly installed on the upper end of the fixed plates 21. A connecting plate 22 is fixedly connected to the lower part of the fixed plates 21 via the telescopic rod 25. Support rods 24 are fixedly connected to both sides of the lower part of the connecting plate 22. Driven by the cylinders 29 at both ends, the telescopic rod 25 can extend and retract vertically, driving the two support rods 24 to move vertically. Directional movement; Limiting rods 26 are fixedly installed on the upper end of the connecting plate 22 and on both sides of the telescopic rod 25. The upper end of the limiting rod 26 extends upward and passes through the fixed plate 21, forming a sliding connection with the fixed plate 21. When the cylinder 29 drives the telescopic rod 25 to extend and retract in the vertical direction, the support rod 24 can slide along the axial direction of the limiting rod 26. The limiting rod 26 can limit the support rod 24 in the radial direction, so that it can move stably in the vertical direction, prevent movement deviation, and prevent damage to the device, thereby improving the stability of movement.
[0032] A support plate 23 is positioned below the support rod 24. Adjusting screws 27 are fixedly connected to the middle of both ends of the support plate 23. The upper ends of the adjusting screws 27 extend upwards, passing through the connecting plate 22 and the fixed plate 21 respectively. Adjusting nuts 271 are threaded onto the outer circumference of the adjusting screws 27. The adjusting nuts 271 are positioned above the fixed plate 21, and the vertical adjustment of the support plate 23 can be achieved by rotating the adjusting nuts. Limiting rods 28 are slidably connected to the four corners of the support plate 23. The limiting rods 28 are vertically oriented, with their lower ends passing through the support plate 23 and fixedly connected to the bottom of the water tank 11. Their upper ends extend upwards and pass through the fixed plate 21, forming a sliding connection with the fixed plate 21. When the adjusting nuts 271 are rotated, the support plate 23 can slide vertically along the limiting rods 28, preventing deviation of the support plate 23 in the vertical direction and improving the stability of the movement and adjustment.
[0033] Reference Figure 2 As shown, the cleaning disc 3 can be placed on the upper end of two support rods 24. The upper end of the cleaning disc 3 extends outward along both sides of the support rods 24 to form a limiting part 32. The cleaning disc 3 can be embedded between the two support rods 24 and abuts against the upper end of the support rods 24 through the limiting parts 32 on both sides to form a limiting support. Several limiting holes 31 are opened inside the cleaning disc 3. The workpiece 4 has a first end 41 and a second end 42. The first end 41 of the workpiece 4 can pass through the limiting hole 31, so that the workpiece 4 can be partially embedded in the limiting hole 31. The second end 42 of the workpiece 4 is located at the upper end of the limiting hole 31. The outer periphery of the workpiece 4 abuts against the inner periphery of the limiting hole 31 to form a limiting installation.
[0034] In this embodiment, the workpiece 4 to be cleaned is a tapered roller with an overall frustum-shaped structure. During installation, the small diameter section of the workpiece 4 can be embedded in the limiting hole 31, with part of the workpiece 4 extending downward to the lower side of the limiting hole 31 and part remaining on the upper side of the limiting hole 31. An annular contact surface is formed between the outer periphery of the workpiece 4 and the limiting hole 31, which is the clamping contact area. This contact area is prone to generating cleaning dead corners during the cleaning process.
[0035] Reference Figure 3 As shown, the telescopic rod 25 is driven by the cylinder 29 to move the cleaning disc 3 up and down. During the process of the cleaning disc 3 loading the workpiece 4 and lowering it for cleaning, it has a first cleaning position and a second cleaning position.
[0036] When the cleaning disc 3 is in the first cleaning position, under the driving action of the cylinder 29, the cleaning disc 3 can completely immerse the workpiece 4 in the cleaning liquid of the water tank 11. The first end 41 (i.e., the small diameter end) of several workpieces 4 placed in the bottom cleaning disc 3 leaves an appropriate gap with the support plate 23. Then the ultrasonic cleaner is turned on to perform the first cleaning of the workpiece 4. Since the workpiece 4 is installed in the limiting hole 31, it will press against the inner circumference of the limiting hole 31, forming a dead corner for cleaning, and it is impossible to form a comprehensive cleaning of the workpiece 4. Therefore, after cleaning for a period of time, the cylinder 29 will start again, driving the cleaning disc 3 to continue to move downward a distance, so that the first end 41 of the workpiece 4 placed in the bottom cleaning disc 3 abuts against the support plate 23, and the support plate 23 can push the workpiece 4 upward a certain distance. At this time, the contact position of the workpiece 4 and the limiting hole 31 is separated from each other, and the supporting part of the workpiece 4 changes from the outer circumference to the bottom surface, so that the clamping contact area can be converted, and the two contact areas can be cleaned separately, avoiding the formation of a cleaning dead corner in the contact area.
[0037] Furthermore, in this embodiment, the cleaning tray 3 can also adopt a stacked structure. By stacking the cleaning trays 3, the number of workpieces 4 that can be cleaned in a single operation can be increased. The stacked cleaning trays 3 can enable the simultaneous cleaning of a large number of workpieces, thereby improving work efficiency.
[0038] Reference Figures 4-7 As shown, a step portion 33 is provided on the inner periphery of the cleaning tray 3 near the upper end, and a step portion 34 is provided on the outer periphery of the cleaning tray 3 near the bottom end. The cleaning trays 3 can be stacked and installed by the cooperation between the step portion 33 and the step portion 34.
[0039] Reference Figure 4 As shown, when the cleaning trays 3 are stacked, the limiting holes 31 of different cleaning trays 3 are aligned vertically, and the workpieces 4 can be positioned vertically relative to each other at the same limiting hole 31. Furthermore, after the cleaning trays 3 are stacked, they maintain a consistent vertical alignment with an appropriate gap, meaning there is a certain gap between the upper end of the lower workpiece 4 and the lower end of the upper workpiece 4. At this time, an annular contact surface is formed between the outer periphery of the workpiece 4 and the limiting hole 31, and the cleaning dead zone in the contact area is located on the outer periphery of the workpiece 4.
[0040] Reference Figure 6 , Figure 7As shown, after cleaning for a period of time, the cylinder 29 will start again, driving the cleaning disc 3 to continue moving downward a distance, so that the first end 41 of the workpiece 4 placed in the bottom cleaning disc 3 abuts against the support plate 23, and the support plate 23 can push the workpiece 4 upward a certain distance; at the same time, the bottom workpiece 4 will rise, so that the second end 42 of the workpiece 4 in the bottom cleaning disc 3 abuts against the first end 41 of the workpiece 4 in the upper cleaning disc 3. The second end 42 (i.e., the upper end) of the lower workpiece 4 will press against the first end 41 (i.e., the lower end) of the upper workpiece 4. The workpieces 4 in each layer press against each other in sequence, so that the workpieces 4 in the cleaning tray 3 move upward relative to the cleaning tray 3 by a distance. The outer periphery of the workpiece 4 no longer presses against the inner periphery of the limiting hole 31, forming a certain gap and remaining stationary. This position is the second cleaning position of the cleaning tray 3. Ultrasonic cleaning is continuously performed to clean the workpiece 4 for the second time. After the cleaning is completed, the cylinder 29 is started to drive the cleaning tray 3 back to the initial position. The operation can be repeated by replacing the cleaning tray 3. This can fully improve the cleaning efficiency of the workpiece 4 and achieve comprehensive cleaning of the workpiece 4.
[0041] Specifically, the limiting hole 31 opened in the cleaning disc 3 can be set to a specific size according to the workpiece 4 of different sizes. By changing the cleaning disc 3, the workpiece 4 of different sizes can be cleaned. Since the drive mode of the cylinder 29 is set and not changed, when the size of the workpiece 4 placed in the cleaning disc 3 changes, the axial distance of the workpiece 4 changes. Therefore, it is necessary to manually rotate the adjusting nut 271 to control the appropriate distance between the support plate 23 and the workpiece 4, so as to facilitate the comprehensive cleaning of the workpiece 4.
[0042] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
