Description

Technical Field

[0001] This invention relates to the field of cage processing technology, and in particular to a cage grinding and cleaning production line. Background Technology

[0002] After stamping or machining, bearing cages often have residual burrs, flash, and oil stains on their surface, requiring multiple processes: "feeding → vibratory polishing to remove burrs → brightening → cleaning → sorting." Existing production lines typically use a linear layout, with a single elevator for feeding, a single vibratory polishing machine, and a single vibrating screen for sorting, connected in series via belts or chutes. The existing production lines have the following problems: (1) The equipment is arranged in a straight line, which occupies a large area and the overall production line path is long, which will affect production efficiency to a certain extent. (2) When the feeding equipment is fitted with a retainer, it is difficult to ensure that the material enters the subsequent processing equipment evenly and stably. For example, some feeding equipment relies solely on a simple tilting hopper for feeding, which can easily lead to material accumulation, blockage, or excessive material being dumped at once during the feeding process; (3) Traditional polishing machines usually use a single specification of abrasive, which cannot penetrate into narrow parts such as cage windows and ball pockets, easily leading to local burr residue; if the polishing time is extended, it will over-grind the already smoothed surface and reduce dimensional accuracy. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a cage grinding and cleaning production line. The discharge directions of the two sets of vibratory polishing equipment are perpendicular, the overall structure is compact, and the discharge from the two sets of vibratory polishing equipment can enter the sorting equipment in an orderly manner. Furthermore, a set abrasive, brightener, and cleaning agent are used to ensure the polishing effect of the cage.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: An embodiment of the present invention provides a cage grinding and cleaning production line, including a feeding device, a vibratory polishing device and a sorting device. Two sets of the feeding device and two sets of vibratory polishing devices are provided, wherein the discharge direction of the two sets of vibratory polishing devices is arranged perpendicularly to the inlet end of the sorting device. The feeding device includes a feeding hopper, a lifting mechanism, and a tilting mechanism, with the tilting mechanism connected between the lifting mechanism and the feeding hopper. In the initial state, the feeding hopper forms a set angle with the horizontal plane so that its discharge end is higher than the other end. The vibratory polishing equipment is connected to an abrasive slurry tank and a brightener tank. The abrasive slurry tank is used to provide a set amount of abrasive to the vibratory polishing equipment, and the brightener tank is used to provide a set amount of brightener to the vibratory polishing equipment.

[0005] As a further implementation, the tilting mechanism includes a tilting cylinder and a hinge. The hinge is located near the discharge end of the feeding hopper, the tilting cylinder is fixed to the upper side of the lifting mechanism, and the piston rod end of the tilting cylinder is connected to the other end of the feeding hopper.

[0006] As a further implementation, the vibratory polishing equipment includes a vibratory screen and a vibratory polishing machine arranged in sequence, wherein the vibratory polishing machine is connected to a polishing slurry tank and a brightener tank.

[0007] As a further implementation, in the initial state, the feeding hopper is lower than the vibrating screen; in the feeding state, the lifting mechanism is used to raise the feeding hopper so that the discharge end of the feeding hopper is higher than the vibrating screen.

[0008] As a further implementation, the vibrating screen is equipped with an adjusting baffle.

[0009] As a further implementation, the abrasive in the grinding fluid tank comprises red triangular stones and spherical high-alumina ceramics.

[0010] As a further implementation, the vibratory polisher is also connected to a cleaning agent tank, wherein the amount of cleaning agent added from the cleaning agent tank to the vibratory polisher is less than the amount of brightener added.

[0011] As a further implementation, the amount of cleaning agent added is 400ml to 600ml, and the amount of cleaning agent added is 150ml to 250ml.

[0012] As a further implementation, the sorting equipment includes a vibrating sorting screen equipped with a spray system for rinsing the surface of the polished cage.

[0013] As a further implementation, the vibrating sorting screen is equipped with an adjusting baffle.

[0014] The beneficial effects of this invention are as follows: (1) The feeding device and the vibratory polishing device of the present invention are each set in two groups. The discharge direction of the two groups of vibratory polishing devices is perpendicular, the overall structure is compact, and the discharge of the two groups of vibratory polishing devices can enter the sorting device in an orderly manner, while improving the space utilization rate.

[0015] (2) In the initial state, the feeding hopper of the present invention is at a certain angle to the horizontal plane, so that the discharge end is higher than the other end. This ensures that the material will not slip off due to gravity when it is loaded into the retainer, thus ensuring the stability of the feeding process. Only when the lifting mechanism lifts the feeding hopper to a certain height and flips it through the flipping mechanism will the material be slowly and evenly poured into the vibratory polishing equipment, avoiding the problems of material accumulation, blockage or excessive dumping at one time, and providing a stable and uniform material supply for the subsequent polishing process.

[0016] (3) The abrasive of the present invention contains red triangular stones and spherical high-alumina ceramic. The red triangular stones can quickly cut the burrs and flash on the cage window and the edge of the ball pocket. The high-alumina ceramic spheres can penetrate into narrow gaps and hole walls to complete micro-beveling without producing secondary burrs. The amount of cleaning agent added is 400ml to 600ml, and the amount of cleaning agent added is 150ml to 250ml. The high-alumina ceramic itself has high polishing ability. Combined with the surfactant and extreme pressure agent in the brightener, it can form a uniform mirror surface on the cage surface. The weakly alkaline cleaning agent can quickly remove oil stains, abrasive debris and brightener residue. Attached Figure Description

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] Example 1: This embodiment provides a cage grinding and cleaning production line, such as Figures 1-4As shown, it includes a feeding device 1, a vibratory polishing device 2, and a sorting device 3. The feeding device 1 and the vibratory polishing device 2 are each set in two. The feeding device 1 and the vibratory polishing device 2 are in one-to-one correspondence. The discharge port of one set of vibratory polishing devices 2 corresponds to one end of the sorting device 3, and the discharge port of the other set of vibratory polishing devices 2 corresponds to one side of the sorting device 3, so that the discharge direction of the two sets of vibratory polishing devices 2 is perpendicular. The overall structure is compact and ensures that the discharge of the two sets of vibratory polishing devices 2 can enter the sorting device 3 in an orderly manner.

[0022] Specifically, such as Figure 3 and Figure 5 As shown, the feeding device 1 includes a feeding hopper 4, a lifting mechanism 5, and a tilting mechanism, with the tilting mechanism connected between the lifting mechanism 5 and the feeding hopper 4. One end of the feeding hopper 4 is closed, and the other end is open, i.e., the discharge end. The discharge end of the feeding hopper 4 faces the side where the vibratory polishing device 2 is located. Initially, the lifting mechanism 5 is in a compressed state, and the bottom surface of the feeding hopper 4 is tilted at a certain angle relative to the horizontal plane, so that the closed end of the feeding hopper 4 is lower than the open end. This tilting state prevents the feeding hopper 4 from falling out from the open end when it is full of the retainer.

[0023] In this embodiment, the lifting mechanism 5 adopts an existing hydraulically powered scissor lift structure.

[0024] The tilting mechanism includes a tilting cylinder 6 (or pneumatic cylinder) and a hinge 7. The hinge 7 connects the bottom surface of the feeding hopper 4 and the top surface of the lifting mechanism 5, and is positioned near the open end of the feeding hopper 4. The top of the tilting cylinder 6 is connected to the closed end of the feeding hopper 4, and the bottom of the tilting cylinder 6 is mounted on the top surface of the lifting mechanism 5, with a certain gap between it and the hinge 7. Initially, the tilting cylinder 6 is in a retracted state and is positioned against the top surface of the lifting mechanism 5; the angle between the bottom surface of the feeding hopper 4 and the horizontal plane is 14°. When the feeding hopper 4 needs to be tilted, the piston rod of the tilting cylinder 6 extends and lifts the closed end of the feeding hopper 4. Under the action of the hinge 7, the open end gradually faces downward, thereby achieving the tilting and unloading of materials. Figure 5 As shown, when the feeding hopper 4 is in the tilted feeding state, the angle between the bottom surface of the feeding hopper 4 and the horizontal plane is 60°.

[0025] The working principle of the feeding device 1 in this embodiment is as follows: the retainer is installed into the feeding hopper 4, the feeding hopper 4 is raised to a certain height and then gradually tilted, and the retainer is slowly tilted and fed into the vibratory polishing device 2. After the feeding is completed, the feeding hopper 4 returns to its original position and waits for the next batch of feeding.

[0026] like Figures 1-4As shown, the vibratory polishing equipment 2 includes a vibratory screen 8 and a vibratory polishing machine 12. The vibratory screen 8 includes a vibratory hopper 9, which, based on the action of the vibratory motor 10 and the vibrating body, causes the retainer to enter the vibratory polishing machine 12. An adjusting baffle 11 is installed near the discharge end of the vibratory hopper 9. The height of the adjusting baffle 11 is adjustable to adjust the amount of material discharged. When the feeding hopper 4 is in its initial state, its height is lower than that of the vibratory screen 8. When the retainer is transferred from the feeding device 1 to the vibratory screen 8, the discharge end of the feeding hopper 4 is made higher than that of the vibratory screen 8 by the action of the lifting mechanism, realizing lifting for feeding and tilting for discharging.

[0027] The vibratory polisher 12 is located at the discharge end of the vibrating screen 8. The vibratory polisher 12 is connected to the polishing slurry tank 13, the brightener tank 14, and the cleaning agent tank. The polishing slurry tank 13 is used to provide polishing slurry to the vibratory polisher 12, the brightener tank 14 is used to provide brightener to the vibratory polisher 12, and the cleaning agent tank is used to provide cleaning agent to the vibratory polisher 12. The polishing slurry, brightener, and cleaning agent are all transported by pumping.

[0028] In this embodiment, the polishing fluid contains red triangular stones and white spherical high-alumina ceramic. The red triangular stones are 5×5mm brown corundum, and the high-alumina ceramic has a diameter of 2mm. The brown corundum triangular stones have high hardness and sharp edges, which can quickly cut burrs and flash from the cage window and ball pocket edge. The 5×5mm brown corundum is suitable for small-sized cages (around 120mm). The small-sized high-alumina ceramic spheres can penetrate into narrow slits and hole walls to complete micro-beveling without producing secondary burrs. The amount of brightener added is 400ml-600ml, and the amount of cleaning agent added is 200ml-150ml-250ml. The high-alumina ceramic itself has high polishing ability, and together with the surfactant and extreme pressure agent in the brightener, a uniform mirror surface can be formed on the cage surface. The weakly alkaline cleaning agent can quickly remove oil, polishing debris, and brightener residue. The preferred amount of brightener is 500ml, and the preferred amount of cleaning agent is 200ml.

[0029] The vibratory polishing machine 12 in this embodiment mainly consists of a vibratory motor 10, support springs, and a base, which are existing equipment and will not be described in detail here. After the vibratory polishing machine 12 is started, the polishing fluid, brightener, and cleaning agent are automatically injected into the vibratory polishing machine 12. According to the principle of spiral tumbling flow and vibration, the vibratory polishing machine 12 causes the retainer and the tumbling abrasive to grind against each other. Under the action of the polishing fluid, brightener, and cleaning agent, the effect of removing burrs and polishing is achieved. After completion, the vibratory polishing machine 12 automatically stops, and the pneumatic valve 19 on it automatically opens to drain the liquid. At the same time as draining the waste liquid, the abrasive is rinsed with water. After discharge, the pusher cylinder 15 pushes the cleaned material into the screen plate, and then the material is vibrated to discharge, so that the retainer enters the sorting device 3.

[0030] The sorting equipment 3 includes a vibrating sorting screen, which consists of a vibrating motor 10, a vibrating trough 16, and a perforated rubber-lined screen plate 17. The perforated rubber-lined screen plate 17 is installed inside the vibrating trough 16, and the vibrating motor 10 is installed at the bottom of the vibrating trough 16. The vibrating sorting screen separates the retainer and the abrasive based on vibration. Figure 1 and Figure 2 As shown, an adjusting baffle 11 is also installed at the discharge end of the vibrating sorting screen. The vibrating sorting screen is equipped with a spray system 18, which sprays and washes the surface of the retainer; in this embodiment, the spray pressure is set to 0.2 MPa.

[0031] In this embodiment, the discharge direction of two sets of vibratory polishing equipment 2 is arranged perpendicularly at the inlet end of the sorting equipment 3, so that the flow path of the material from the vibratory polishing equipment 2 to the sorting equipment 3 is shorter and more direct, reducing the dwell time and collision damage of the material during the transmission process, while improving the space utilization rate.

[0032] In this embodiment, the feeding device 1 has a feeding hopper 4 at a certain angle to the horizontal plane in the initial state, so that the discharge end is higher than the other end (closed end). This prevents the material from slipping off due to gravity when the cage is installed, ensuring the stability of the feeding process. Only when the lifting mechanism lifts the feeding hopper 4 to a certain height and flips it through the flipping mechanism will the material be slowly and evenly poured into the vibratory polishing device 2, avoiding the problems of material accumulation, blockage, or excessive dumping at one time, and providing a stable and uniform material supply for subsequent polishing processes. By adjusting the height of the lifting mechanism 5 and the angle of the flipping mechanism, the feeding speed and feeding amount can be precisely controlled. The lifting mechanism 5 and the flipping mechanism work together to adapt to the feeding needs of cages of different specifications, shapes, and weights.

[0033] This embodiment sets a precise supply of abrasive and brightener, enabling the vibratory polishing equipment 2 to operate in optimal working condition. This reduces the downtime caused by insufficient abrasive or excessive brightener, and improves equipment utilization and production efficiency.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
