Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and more specifically to a bearing roller feeding mechanism. Background Technology

[0002] As is well known, bearing rollers are the load-bearing components in a bearing and are an important part of rolling bearings. Rolling bearings generally consist of rings, rolling elements, and a cage, that is, several rolling elements are arranged between the inner and outer rings. Rolling bearings reduce friction loss by converting the sliding friction between the rotating shaft and the bearing housing into rolling friction.

[0003] Before assembling rolling bearings, the rings, steel balls, rollers, and cages need to be processed. After passing the inspection, they enter the assembly workshop for assembly. The specific process includes demagnetizing the parts, cleaning, sorting and grouping the inner and outer raceway dimensions, and fitting them together. Finally, they are packaged and placed in the finished product warehouse.

[0004] After the bearing is assembled, during the feeding process, the bearing enters the hopper of the feeder and falls into the conveying area. During this process, the bearing falls rapidly in the cylindrical hopper under its own weight. The falling process cannot be slowed down, and the collision and impact when it falls into the conveying area will cause certain damage to the bearing, resulting in the loosening of the rollers inside the bearing, which will lead to certain deficiencies in bearing feeding. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, one objective of this utility model is to provide a bearing roller feeding mechanism to solve the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides a bearing roller feeding mechanism, including a feeding machine and a material rack disposed on the feeding machine. The material rack has multiple material bins disposed along its length. Multiple baffles are hinged to each material bin in the circumferential direction, and each baffle is provided with an elastic reset member. A limiting groove is formed in the hinge joint between each baffle and each material bin, and each baffle is provided with a protrusion that cooperates with each limiting groove.

[0007] Preferably, each of the limiting grooves has a triangular structure.

[0008] Preferably, when each of the baffles is in a vertical state, the maximum distance between the elastic reset members on each of the hoppers is less than the feed port diameter of each of the hoppers.

[0009] Preferably, when each of the baffles is in an inclined state, the maximum distance between the elastic reset members on each of the hoppers is slightly smaller than the feed port diameter of each of the hoppers.

[0010] Preferably, each of the elastic reset elements is an arc-shaped structure.

[0011] Preferably, the feeding machine is provided with a feeding tray, and the feeding tray is provided with a material placement trough.

[0012] Preferably, the material trough is provided with a limiting part that cooperates with the bearing.

[0013] Preferably, the feeding machine is also provided with a feeding trough, and the feeding trough is provided with a discharging trough that cooperates with the limiting part.

[0014] In the above technical solution, the bearing roller feeding mechanism provided by this utility model has the following beneficial effects: After the bearing is placed into the hopper through the opening, during the falling process, the bearing will abut against the elastic reset member on the baffle, forcing the baffle to rotate outward so that the bearing can continue to fall. Under the abutment of the elastic reset member against the bearing, the elastic reset member deforms and buffers and decelerates the bearing to a certain extent, so that the bearing falls slowly onto the conveying area. This weakens or even avoids the bearing falling rapidly into the cylindrical hopper under its own weight. The falling process cannot be decelerated, and the collision impact when it falls onto the conveying area will cause certain damage to the bearing, resulting in the loosening of the rollers inside the bearing.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-8 A bearing roller feeding mechanism is used to solve the problem that during the feeding process after bearing assembly, the bearing enters the hopper of the feeder and falls to the conveying area. During this process, the bearing falls rapidly in the cylindrical hopper under its own weight. The falling process cannot be decelerated, and the collision and impact when it falls on the conveying area will cause certain damage to the bearing, resulting in the loosening of the rollers inside the bearing and causing certain deficiencies in bearing feeding.

[0028] As a further technical solution proposed in this utility model, it includes a feeding machine 1 and a material rack 2, which is disposed on the feeding machine 1. Multiple material bins 2.1 are disposed along the length of the material rack 2. Multiple baffles 2.2 are hinged to the circumference of each material bin 2.1. Each material bin 2.1 has three baffles 2.2, and each baffle 2.2 has an elastic reset member 2.3. A limiting groove 2.4 is formed at the hinge point between each baffle 2.2 and each material bin 2.1. Each baffle 2.2 has a protrusion 2.5 that cooperates with each limiting groove 2.4. Specifically, the bearing 4 is located at the opening of the material bin 2.1. After insertion, during the descent of the bearing 4, it will come into contact with the elastic reset member 2.3 on the baffle 2.2, forcing the baffle 2.2 to rotate outward so that the bearing 4 can continue to fall. Under the contact action of the elastic reset member 2.3 against the bearing 4, the elastic reset member 2.3 deforms and provides a certain buffer and deceleration for the bearing 4, so that the bearing 4 falls slowly onto the conveying area. This weakens or even avoids the bearing falling rapidly into the cylindrical hopper under its own weight. The descent process cannot be decelerated, and the impact when it falls onto the conveying area will cause certain damage to the bearing, resulting in the loosening of the rollers inside the bearing.

[0029] In this embodiment, the hopper 2.1 is connected to the conveying mechanism (conveyor) of the previous station. The conveying mechanism transports multiple hoppers 2.1 to the bearing 4. The number of hoppers 4 is determined according to the needs of those skilled in the art. Figure 1 As shown in the figure, preferably, the number of hoppers 4 is 3, which can transport three bearings 4 to the feeder 1 at one time.

[0030] In another embodiment of this utility model, each limiting groove 2.4 is generally triangular in structure. When each baffle 2.2 is in a vertical state, the maximum distance between the elastic reset members 2.3 on each hopper 2.1 is less than the feed inlet diameter of each hopper 2.1. When each baffle 2.2 is in an inclined state, the maximum distance between the elastic reset members 2.3 on each hopper 2.1 is slightly less than the feed inlet diameter of each hopper 2.1. Furthermore, with Figure 6 and Figure 7 For reference, when the elastic reset member 2.3 in the hopper 2.1 is not abutted by the bearing 4, the baffle 2.2 is in a vertical state. At this time, the protrusion 2.5 abuts against the left side of the triangle of the limiting groove 2.4. When the elastic reset member 2.3 contacts the bearing 4 and forces it to rotate, after rotating to its maximum extent, it abuts against the right side of the other triangle. Figure 8 As shown in the diagram, the rotation of the baffle 2.2 is restricted by the limiting groove 2.4, as follows: Figure 4 As shown in the figure, this is the maximum angle of rotation of the baffle 2.2. In this state, the distance between the arc-shaped parts of the elastic reset member 2.3 is slightly smaller than the diameter of the hopper 2.1, so as to continue to limit and buffer the falling bearing 4. Under its own weight, the bearing 4 comes into contact with the elastic reset member 2.3 and is forced to deform and continue to fall until it lands on the feeding trough 1.4 of the feeder 1.

[0031] In another embodiment of this utility model, each elastic reset member 2.3 is specifically an arc-shaped structure, which is an elastic sheet. The arc-shaped elastic sheet buffers and decelerates the falling bearing 4. During the outward rotation of the baffle 2.2 and the deformation of the elastic sheet due to the pressure of the bearing 4's gravity, it plays a buffering role on the bearing 4.

[0032] In another embodiment of the present invention, a feeding plate 1.1 is slidably arranged on the feeding machine 1, and a material placement groove 1.2 is opened on the feeding plate 1. Furthermore, a second cylinder for driving its sliding is also provided on the feeding plate 1. It is not shown in the figure and is prior art, so it will not be described in detail.

[0033] In another embodiment of the present invention, preferably, a limiting part 1.3 that cooperates with the bearing 4 is provided on the material placement groove 1.2. The limiting part 1.3 is specifically a circular structure that is adapted to the bearing 4 and limits the bearing 4 that falls into the material placement groove 1.2, thereby improving its stability when the feeding tray 1.1 moves.

[0034] In another embodiment of this utility model, the feeding machine 1 is further provided with a feeding trough 1.4, and a third cylinder (not shown in the figure) is also provided on the feeding trough 1.4. This cylinder is used to push the bearing 4 located on the feeding trough 1.4 into the discharge trough 1.5. The feeding trough 1.4 is provided with a discharge trough 1.5 that cooperates with the limiting part 1.3. A cylinder 3 is also provided above the discharge trough 1.5. Figure 1 As shown in the figure, it is set on the material rack 2 of the feeder 1. The cylinder 3 is used to push the bearing 4 located at the unloading trough 1.5 downwards so that it falls into the feeding tray 1.1. This is existing technology and will not be described in detail.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
