Description

Technical Field

[0001] This utility model relates to the field of bearing feeding devices, specifically an automatic feeding device for automotive bearings. Background Technology

[0002] Automotive bearings are key components in vehicle transmission systems, primarily used to support rotating shafts, reduce friction, and withstand radial or axial loads, ensuring efficient and smooth operation of mechanical parts. Depending on their function, they can be categorized into wheel hub bearings (supporting wheels), gearbox bearings (transmitting power), and engine bearings (such as crankshaft bearings). Common structures include ball bearings, roller bearings, and tapered roller bearings. Modern automotive bearings require high precision, wear resistance, and high-temperature resistance; therefore, they require a loading device during assembly.

[0003] For example, patent announcement number CN222063154U discloses a feeding device for bearing processing, including a disc. A turntable is rotatably connected to the inner wall of the disc. A positioning plate is elastically connected to the inner wall of the right end of the turntable via a return spring. A fixing block is fixedly connected to the top of the positioning plate. A mounting frame is fixedly connected to the outer wall of the disc. A feeding bucket is inserted into the top of the mounting frame. An extrusion plate is fixedly connected to the outer wall of the feeding bucket. A sleeve is fixedly connected to the bottom end of the disc. A driving mechanism is provided on the inner wall of the sleeve, and a protective plate is hinged to the outer wall of the sleeve. In this invention, bearings are pre-placed in the feeding bucket for feeding. The rotation of the turntable causes the bearings to continuously enter the placement slots on the turntable, allowing the positioning plate to push the bearings onto the worktable or transmission machine. This eliminates the need to manually remove each bearing to the worktable, simplifying and improving the overall feeding efficiency in actual operation.

[0004] In the aforementioned technology, the feeding device uses a turntable to feed bearings one by one, but manual placement of the bearings into the feeding cylinder is still required. At the same time, the limited space inside the feeding cylinder makes it impossible to store a large number of bearings, resulting in frequent refills and reduced feeding efficiency. Therefore, the market urgently needs to develop an automatic feeding device for automotive bearings to help people solve the existing problems. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of an automatic feeding device for automotive bearings, comprising a feeding box 1, a centrifugal turntable 2 rotatably connected to the center of the feeding box 1, levers 106 fixedly connected to the center of both ends of the inner wall of the feeding box 1 and to the upper end of the centrifugal turntable 2, the outer ends of the two levers 106 being fixedly connected to the inner wall of the feeding box 1 by screws, a discharge port 103 provided at the rear end of one side of the upper end of the centrifugal turntable 2 and on the inner wall of the feeding box 1, an arc-shaped baffle 104 fixedly connected to the inner wall of the feeding box 1 and to the front end of the discharge port 103, and an arc-shaped baffle 104 fixedly connected to the outer wall of the centrifugal turntable 2 and to the discharge port 103. A discharge conveyor belt 5 is fixedly connected to one side of the feed inlet 103. By placing a large number of bearings on the centrifugal turntable 2 inside the feed box 1, the centrifugal turntable 2 rotates and drives the bearings to rotate, causing the bearings to move to the inner wall of the feed box 1 under the action of centrifugal force. After the bearings contact the inner wall of the feed box 1, they rotate along the inner wall. The arc-shaped baffle 104 guides the bearings rotating along the inner wall of the feed box 1 one by one to the discharge port 103, so that the bearings are discharged from the discharge port 103 and enter the discharge conveyor belt 5 for output. The vertical bearings on the centrifugal turntable 2 are fixedly set by two levers 106 to flatten them as they move.

[0024] Please see Figure 2 and Figure 4 A ring-shaped connector 201 is fixedly connected to the middle of the upper end face of the centrifugal turntable 2. A drive shaft 3 is provided in the middle of the centrifugal turntable 2 and the ring-shaped connector 201. The lower end of the drive shaft 3 extends out of the lower end of the centrifugal turntable 2 and is fixedly connected to a fixing ring 301. The ring-shaped connector 201 and the fixing ring 301 are fixedly connected by multiple first bolts 202. The drive shaft 3 drives the fixing ring 301 to rotate, so that the fixing ring 301 drives the centrifugal turntable 2 to rotate. A first limiting tube 101 is fixedly connected to the middle of the lower end face of the feeding box 1. A drive motor 102 is fixedly connected to the middle of the lower end face of the feeding box 1. The upper end of the output shaft of the drive motor 102 passes through the first limiting tube 101 and extends to the lower end of the centrifugal turntable 2 and is connected to the lower end of the drive shaft 3 through a reducer. The drive motor 102 drives the drive shaft 3 to rotate.

[0025] Please see Figure 2 and Figure 3 Support wing plates 105 are fixedly connected to the upper ends of both sides of the outer wall of the feeding box 1. The upper ends of the two support wing plates 105 are connected to a stabilizing plate 4. The two sides of the stabilizing plate 4 are fixedly connected to the two support wing plates 105 by second bolts 401. A second limiting tube 402 is fixedly installed in the middle of the stabilizing plate 4. The upper end of the transmission shaft 3 extends out of the upper end of the annular connecting piece 201 and is inserted into the interior of the second limiting tube 402. The upper end of the transmission shaft 3 is connected to the inner wall of the second limiting tube 402 by a bearing 403, so that the second limiting tube 402 limits the upper end of the transmission shaft 3 and ensures the stability of the rotation of the transmission shaft 3.

[0026] Working Principle: During operation, automotive bearings are placed in batches onto the centrifugal turntable 2 inside the feeding box 1. The drive motor 102 is started, driving the transmission shaft 3 to rotate via a reducer. The transmission shaft 3 drives the centrifugal turntable 2 to rotate via a fixed ring 301 and an annular connector 201. Under centrifugal force, the bearings move radially outward along the centrifugal turntable 2 and contact the inner wall of the feeding box 1, then move in a circular motion along the inner wall. During rotation, vertically placed bearings are leveled and turned to a horizontal state when passing the fixed lever 106. When the bearings move to the position of the arc-shaped baffle 104, they are gradually guided to the discharge port 103, achieving orderly single discharge. The discharged bearings fall onto the discharge conveyor belt 5 and are transported to the next station. The second limiting tube 402 radially positions the upper end of the transmission shaft 3 via the bearing 403, ensuring smooth operation of the centrifugal turntable 2. This device achieves automatic arrangement and conveying of bearings through centrifugal force, eliminating the need for manual loading one by one. Furthermore, the box volume can accommodate a large number of bearings, significantly improving feeding efficiency and continuity.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
