Detailed Implementation

[0030] 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.

[0031] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Please see Figures 1-6The diagram illustrates a feeding device for processing bearing steel rings, comprising a vertical frame 1. The vertical frame 1 is constructed from high-strength metal materials, welded or bolted together, possessing excellent rigidity and stability. It provides reliable support for the entire device, bearing various forces such as gravity, thrust, and pressure generated during the operation of each component. A pushing device 2, a lifting device 3, a unloading device 4, a conveying device 5, and a loading cart 6 are arranged in an orderly fashion on the vertical frame 1. These devices cooperate to form a complete automated feeding system.

[0033] The pushing device 2, conveying device 5, and unloading device 4 are arranged opposite each other on the upright frame 1, forming a continuous material transport path. The pushing device 2 is responsible for pushing the bearing steel rings on the loading cart 6 to the unloading device 4; the unloading device 4 accurately feeds the steel rings into the conveying device 5 through a downward pressing action; the conveying device 5 then transports the steel rings to the subsequent processing station; the lifting device 3 can flexibly adjust the height of the loading cart 6 according to actual production needs to ensure smooth connection between the various devices.

[0034] The feeding device 4 consists of a pressing component 401, a feeding component 402, a limiting component 403, and a guide plate 404. The guide plate 404 is fixedly mounted on the upright frame 1 by bolts. Its surface is provided with an inclined guide surface 405, which can promote the smooth sliding of the bearing steel ring under the action of gravity, and can also prevent the sliding speed from being too fast and causing loss of control or collision. Multiple partitions 406 are evenly distributed on the guide surface 405, and independent guide channels 407 are formed between adjacent partitions 406. The width of each guide channel 407 is exactly matched with the outer diameter of a single bearing steel ring, realizing precise positioning and guidance of the steel ring.

[0035] The pressing assembly 401 includes a set of third linear guide pairs 401a, connecting plates 401b, pressing cylinders 401c, and pressing plates 401d symmetrically distributed on both sides of the upright 1. A connecting plate 401b is fixedly connected to the slider of each third linear guide pair 401a. The connecting plate 401b is made of high-strength metal sheet and is securely connected to the slider by welding or bolting. A pressing cylinder 401c is installed on each side of the upright 1. The cylinder body of the pressing cylinder 401c is connected to the upright 1 via a fixed base, and its telescopic rod is connected to the corresponding connecting plate 401b. A pressing plate 401d is positioned between the two connecting plates 401b, with both ends of the pressing plate 401d fixedly connected to the two connecting plates 401b respectively, forming an integrated pressing structure.

[0036] When the feeding assembly 402 presses down on the outermost bearing steel ring of the guide channel 407, the pressing assembly 401 plays a crucial role. The pressing cylinder 401c drives the connecting plate 401b to move downward along the third linear guide pair 401a, causing the pressing plate 401d to descend synchronously, pressing the pressing plate 401d against the bearing steel ring adjacent to the one to be fed. By applying stable pressure, the movement freedom of the adjacent steel rings is effectively restricted, preventing them from tipping over due to loss of lateral support. This ensures the stability and orderliness of the steel ring arrangement during the feeding process, avoiding problems such as jamming and falling due to steel ring tipping, and ensuring the smooth operation of the entire feeding process.

[0037] The feeding assembly 402 includes two feeding cylinders 402a and a feeding plate 402b symmetrically mounted on the upright 1. The cylinder body of the feeding cylinder 402a is firmly fixed to the upright 1 by a special mounting base, and its telescopic rod is connected to both ends of the feeding plate 402b through a connector to ensure the stability and reliability of power transmission. Multiple feeding teeth 402c are linearly arrayed on the feeding plate 402b. When the feeding cylinder 402a is working, the telescopic rod extends, driving the feeding plate 402b to move downward, and the feeding teeth 402c precisely act on the bearing steel ring at the front end of the guide channel 407, smoothly pressing it into the conveying device 5, realizing the precise feeding of a single steel ring.

[0038] The limiting assembly 403 consists of a Z-shaped mounting plate 403a, a limiting plate 403b, a linear bearing 403c, a light shaft 403d, and a spring 403e. Two Z-shaped mounting plates 403a are bolted to the support frame 1. A linear bearing 403c is installed on the horizontal portion of each Z-shaped mounting plate 403a, and a light shaft 403d passes through each linear bearing 403c, allowing it to slide freely within the bearing. One end of each light shaft 403d is fixedly connected to the side of the limiting plate 403b by welding or other means. A spring 403e is fitted between the light shaft 403d and the limiting plate 403b, initially in a compressed state. Under the elastic force of the spring 403e, the limiting plate 403b consistently applies a certain limiting force to the bearing ring located at the foremost end of the material guide channel 407, preventing the ring from accidentally falling off when not in a feeding state. When the material needs to be unloaded, the bearing steel ring applies pressure to it, causing it to overcome the spring force and move backward, thus releasing the restriction on the steel ring and allowing it to pass smoothly.

[0039] Two lifting devices 3 are provided, located on both sides of the upright 1, forming a symmetrical layout to ensure the stability and balance of the lifting process of the loading vehicle 6. Each lifting device 3 consists of a lifting motor 301, a first transmission screw pair 302, a first linear guide pair 303, and a support plate 304. The screw of the first transmission screw pair 302 is mounted on the upright 1 through a high-precision bearing seat, and one end of the screw is connected to the rotating shaft of the lifting motor 301 through a coupling to ensure efficient and accurate power transmission. The middle part of the support plate 304 is bolted to the screw nut seat of the first transmission screw pair 302, and its two sides are fixedly connected to the sliders of the two first linear guide pairs 303 by bolts or welding. The first linear guide pair 303 consists of a guide rail and a slider, providing precise guidance for the lifting movement of the support plate 304. When the lifting motor 301 is working, it drives the lead screw to rotate, and the lead screw nut seat moves axially on the lead screw, thereby driving the support plate 304 to move smoothly up and down along the first linear guide pair 303, so as to achieve precise adjustment of the height of the loading car 6 to adapt to the loading height requirements of different processing equipment, and also to facilitate the loading, unloading and replacement of the loading car 6.

[0040] The feeding device 2 consists of a mounting frame 201, a pushing frame 202, a pushing plate 203, a second linear guide pair 204, a second transmission screw pair 205, a pushing motor 206, and pushing teeth 207. The mounting frame 201 is firmly fixed to the upright frame 1 by welding or bolting, serving as the support frame for the feeding device 2. The second linear guide pair 204 is symmetrically arranged on the mounting frame 201, providing high-precision guidance for the movement of the pushing plate 203. The second transmission screw pair 205 is mounted on the mounting frame 201, with its screw fixed by a bearing seat, and the screw nut seat bolted to one end of the pushing plate 203. The pushing motor 206 is connected to the screw of the second transmission screw pair 205 via a coupling, converting the motor's rotational motion into the linear motion of the screw. Multiple pushing teeth 207 are linearly arranged on the lower end face of the pushing plate 203, and the spacing between adjacent pushing teeth 207 matches the dimensions of adjacent V-shaped grooves 603 and bearing rings on the loading carriage 6. When the drive motor 206 starts, it drives the lead screw of the second transmission lead screw pair 205 to rotate. The lead screw nut seat drives the push plate 203 to move along the second linear guide pair 204. The push teeth 207 on the push plate 203 push the entire row of bearing steel rings forward against the rear end of the V-groove 603 of the aluminum plate 602 of the loading car 6.

[0041] The loading trolley 6 consists of a trolley frame 601, aluminum plates 602, and casters. The trolley frame 601 is welded from metal materials, possessing sufficient strength and rigidity. Casters with brakes are installed at the bottom for easy movement and positioning of the loading trolley 6. Multiple aluminum plates 602 arranged in an array are mounted on the trolley frame 601. The aluminum plates 602 are made of lightweight, high-strength, and corrosion-resistant aluminum alloy, and have multiple V-grooves 603 machined on them. The design of the V-grooves 603 allows the bearing steel rings to automatically align during placement, ensuring stability and accuracy. The number of V-grooves 603 is consistent with the number of ejector teeth 402c and pusher teeth 207. The spacing between adjacent V-grooves 603, adjacent pusher teeth 207, and adjacent ejector teeth 402c are all the same, ensuring precise coordination between the various components. In addition, the extension plates 604 provided in the middle of both sides of the trolley frame 601 are adapted to the size and position of the support plate 304 of the lifting device 3, so that the support plate 304 can lift the loading trolley 6.

[0042] The conveying device 5 is a belt conveyor 501 inclined on the upright 1. Its inclination angle is the same as the inclination angle of the guide surface 405 of the guide plate 404, and they are on the same plane, ensuring that the bearing steel ring can smoothly slide into the conveyor 501 from the guide channel 407. The side of the conveyor 501 is equipped with an anti-fall baffle 502, an adjusting cylinder 503, a second linear bearing 504 and a second optical shaft 505 connected to the frame of the conveyor 501 by angle iron. The cylinder body of the adjusting cylinder 503 is connected to the outer frame of the conveyor 501 through a mounting base, and its telescopic rod is connected to the anti-fall baffle 502. The second linear bearing 504 and the second optical shaft 505 are arranged in pairs. One end of each second optical shaft 505 is inserted into the corresponding position of the second linear bearing 504, and the other end is fixedly connected to the anti-fall baffle 502 by welding or other means. By adjusting the extension and retraction of the telescopic rod of the cylinder 503, the anti-drop baffle 502 is moved along the second optical axis 505 within the second linear bearing 504. The position of the anti-drop baffle 502 can be flexibly adjusted according to the size of the bearing steel ring, effectively preventing the steel ring from falling during the conveying process and ensuring the safety and stability of the conveying process.

[0043] Working principle:

[0044] During the preparation phase, the operator places the bearing steel rings to be processed sequentially into the V-shaped grooves 603 of the aluminum plate 602 of the loading trolley 6. The design of the V-shaped grooves 603 allows the bearing steel rings to automatically center, ensuring stable placement. Furthermore, the number and spacing of these grooves precisely match the pushing teeth 207 of the pushing device 2 and the discharging teeth 402c of the unloading device 4, laying the foundation for accurate subsequent transport. After loading is complete, the loading trolley 6 is moved into the upright frame 1 using the casters with brakes on its bottom, aligning the extension plates 604 at the center of both sides of the trolley frame 601 with the support plates 304 of the lifting device 3.

[0045] The lifting device 3 is activated, and the two lifting mechanisms symmetrically distributed on both sides of the upright 1 operate synchronously. The lifting motor 301 is powered on and drives the lead screw of the first transmission lead screw pair 302 to rotate through the coupling. Since the middle of the support plate 304 is connected to the lead screw nut seat and the two sides are connected to the sliders of the first linear guide pair 303, when the lead screw rotates, the lead screw nut seat moves along the lead screw axis, driving the support plate 304 to rise and fall smoothly along the first linear guide pair 303, adjusting the loading car 6 to a suitable height, and ensuring smooth docking with the pushing device 2.

[0046] The pushing device 2 starts working, driving the motor 206 to rotate the lead screw of the second transmission lead screw pair 205. The lead screw nut seat is connected to one end of the push plate 203. During the rotation of the lead screw, the lead screw nut seat drives the push plate 203 to move along the second linear guide pair 204 towards the unloading device 4. The pushing teeth 207 on the lower end face of the push plate 203 insert into the rear end of the bearing steel ring in the V-groove 603 of the aluminum plate 602 of the loading carriage 6, pushing the entire row of steel rings forward.

[0047] The components of the feeding device 4 operate in coordination. First, the pressing cylinder 401c of the pressing component 401 drives the connecting plate 401b to move downward along the third linear guide pair 401a, causing the pressing plate 401d to descend synchronously, pressing the bearing steel ring adjacent to the steel ring to be fed, restricting its freedom of movement and preventing it from tipping over. At this time, the limiting plate 403b of the limiting component 403, under the elastic force of the spring 403e, applies a limiting force to the bearing steel ring located at the foremost end of the guide channel 407, preventing it from falling prematurely.

[0048] When the feeding command is issued, the limiting plate 403b, under the squeezing force of the bearing steel ring, overcomes the elastic force of the spring 403e and moves backward, releasing the limitation on the foremost steel ring. Immediately afterwards, the two feeding cylinders 402a of the feeding assembly 402 simultaneously extend their telescopic rods, driving the feeding plate 402b to move downward. The feeding teeth 402c on the feeding plate 402b precisely act on the bearing steel ring at the foremost end of the guide channel 407, smoothly pressing it into the conveying device 5.

[0049] The conveying device 5 receives the bearing steel rings falling from the unloading device 4. Since the inclination angle of the conveyor belt device 501 is the same as and on the same plane as the guide surface 405 of the guide plate 404, the steel rings can smoothly slide into the conveyor belt. During the conveying process, the adjusting cylinder 503, according to the size of the steel rings, moves the anti-drop baffle 502 along the second optical axis 505 within the second linear bearing 504 via the telescopic rod, adjusting the position of the baffle to prevent the steel rings from falling. Finally, the steel rings are stably conveyed to the subsequent processing station, completing the entire feeding process.
