Description

Technical Field

[0001] This utility model relates to the field of bearing needle roller screening technology, and in particular to a bearing needle roller screening machine. Background Technology

[0002] The bearing needle roller screening machine is a specialized piece of equipment used in the bearing manufacturing industry. It is mainly used for precise screening of needle rollers based on their size, shape, and surface quality. Through various technical principles such as vibration, rotation, and pneumatics, combined with high-precision screens, sensors, and sorting mechanisms, it can quickly and efficiently classify needle rollers of different specifications and qualities, remove defective products, and ensure the consistency and reliability of the needle rollers used in bearing assembly. This improves the overall performance and quality of the bearings, and it is widely used in various industries such as machinery manufacturing, automotive industry, and aerospace.

[0003] A search revealed Chinese patent publication number CN219262974U, which discloses a needle roller bearing comprising an outer ring and a plurality of needle rollers, and a spindle. The outer ring is fitted onto the spindle and forms a raceway thereon for the needle rollers to be fully loaded. The needle rollers can slide axially on the spindle, and washers are fitted at both ends of the outer ring in the axial direction. The washers can form a limiting fit with the needle rollers. The spindle has mounting grooves near both ends. Addressing the shortcomings of existing technologies, this invention provides a needle roller bearing that is fully loaded with needle rollers, allows for small axial movement with the outer ring, and has a stable structure. However, if the needle rollers are not moved, they will accumulate in the conveying channel due to their own weight, friction, or uneven feeding, especially at key locations such as bends and screening inlets, easily causing blockages. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bearing needle roller screening machine, which aims to improve the problem in the prior art where, if the needle rollers are not moved, they will accumulate in the conveying channel due to their own weight, friction, or uneven feeding, especially at key locations such as bends and screening inlets, which can easily cause blockages.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bearing needle roller screening machine, comprising a support plate, a toggle mechanism installed on the top of the support plate for toggle bearing needle rollers, a screening mechanism installed at the top of the support plate for screening bearing needle rollers of different specifications, the toggle mechanism comprising a gear, the gear being disposed on the top of the support plate, a rack being disposed on the top of the support plate, the gear being meshed with the rack, an L-shaped rod one being fixedly connected to the rear left end of the rack, an L-shaped rod two being fixedly connected to the right side of the rack, a movable plate being fixedly connected to the outer sides of both the L-shaped rod one and the L-shaped rod two, and a drive assembly being installed at the bottom of the gear.

[0006] Through the above technical solution: the rotational motion of the gear is converted into the linear motion of the rack through meshing with the rack. The motion of the rack then drives the movement of L-shaped rod one and L-shaped rod two, causing the moving plate fixed on the two rods to be displaced. During the sliding process, the moving plate contacts the bearing needle rollers, orderly agitating the scattered bearing needle rollers and tidying them up.

[0007] As a further description of the above technical solution:

[0008] The drive assembly includes a motor, which is disposed on the top front side of the support plate. A connecting shaft is fixedly connected to the top of the motor, and the top of the connecting shaft is fixedly connected to the bottom of the gear.

[0009] The above technical solution involves using the kinetic energy of the motor to drive the connecting shaft to rotate, which in turn drives the gear fixed to the connecting shaft to rotate.

[0010] As a further description of the above technical solution:

[0011] The screening mechanism includes a needle loading box, which is located on the top of the support plate. A connecting rod is provided on the bottom rear side of the needle loading box. A vibrating funnel is provided at the bottom of the needle loading box. A needle feeding tube is provided on the bottom right side of the needle loading box. A needle dispensing box is installed on the top of the support plate. A needle dispensing disc is installed on the top of the needle dispensing box. Multiple needle grooves are equidistantly opened on the outer side of the needle dispensing disc. A height limiting block is provided on the top rear side of the needle dispensing box. A needle outlet tube is provided on the right side of the height limiting block.

[0012] The above technical solution involves the operator pouring needle rollers into the needle box. The needle rollers slowly descend from the top of the needle box to the vibrating funnel at the bottom. The vibration of the vibrating funnel causes the needle rollers to pass through the needle feeding tube in an orderly manner, and finally be transported to the needle distribution plate at the top of the needle distribution box. The needle distribution plate rotates counterclockwise, and the needle grooves equidistantly arranged on its outer edge rotate at a fixed angle each time. When the needle groove carrying the needle roller passes the height limiting block, the height limiting block is trapezoidal, and its inclined surface contacts the needle roller, pushing the needle roller downward to ensure that the needle roller maintains a suitable height. During the rotation of the needle distribution plate, each box at the bottom is provided with a needle hole that matches the thickness of the needle roller. The size of the needle hole is distinguished by a difference of micrometers. When the needle roller passes through the needle hole that matches its own size, it will fall into the corresponding needle box below, thereby achieving precise screening of the thickness of the needle roller.

[0013] As a further description of the above technical solution:

[0014] The top four corners of the support plate are each equipped with corner guards, and screws are threaded onto the outer side of each corner guard.

[0015] The above technical solution involves installing corner protectors on the support plate, which are then fixed with screws.

[0016] As a further description of the above technical solution:

[0017] A support rod is fixedly connected to the top rear left end of the support plate, and a control box is provided on the top of the support rod.

[0018] The above technical solution involves mounting a support rod on a support plate and mounting a control box on the support rod.

[0019] As a further description of the above technical solution:

[0020] A sliding groove is provided on the outer side of the support plate. The sliding groove is opened on the top front side of the needle box. A limiting block is slidably connected to the inner wall of the sliding groove. The top of the limiting block is fixedly connected to the bottom of the rack.

[0021] The above technical solution involves installing a sliding groove on the top of the needle box, within which a limit block slides.

[0022] As a further description of the above technical solution:

[0023] A fixing plate is provided on the outer side of the support plate, and the top of the fixing plate is fixedly connected to the bottom of the motor.

[0024] The above technical solution uses a fixing plate to support the motor.

[0025] As a further description of the above technical solution:

[0026] The top of the support plate is provided with a sloping panel, which is fixedly connected to the outside of the movable plate.

[0027] The above technical solution involves installing a slanted panel on the movable plate.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, after the motor is started, its kinetic energy drives the gear to rotate through the shaft. The gear meshes with the rack, converting the rotational motion into the linear motion of the rack. The movement of the rack drives the L-shaped rod to move, thereby causing the movable plate fixed on the rod to move. When the movable plate slides, it actuates the bearing needle rollers, thereby tidying up the bearing needle rollers.

[0030] 2. In this utility model, the operator pours the roller needles into the needle box. The roller needles pass through the vibrating funnel and the needle feeding tube and finally reach the needle sorting plate. The needle sorting plate rotates counterclockwise. Each time the needle groove rotates through a fixed angle, the roller needles are pushed to a suitable height under the action of the height limiting and clamping block. The needle sorting plate continues to rotate, and the roller needles fall into the needle box below through the size that matches the needle hole, thus completing the screening.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a bearing needle roller screening machine, including a support plate 1. A turning mechanism 2 is installed on the top of the support plate 1, used to turn the bearing needle rollers. A screening mechanism 3 is installed at the top of the support plate 1, used to screen bearing needle rollers of different specifications. The turning mechanism 2 includes a gear 201, which is disposed on the top of the support plate 1. A rack 202 is disposed on the top of the support plate 1, and the gear 201 meshes with the rack 202. An L-shaped rod 1 203 is fixedly connected to the rear left end of the rack 202, and an L-shaped rod 204 is fixedly connected to the right side of the rack 202. The outer sides of both the L-shaped rod 1 203 and the L-shaped rod 204 are fixedly connected. There is a movable plate 205, and a drive assembly 206 is installed at the bottom of the gear 201. The drive assembly 206 includes a motor 2061, which is located on the top front side of the support plate 1. A connecting shaft 2062 is fixedly connected to the top of the motor 2061. The kinetic energy of the motor 2061 drives the connecting shaft 2062 to rotate. The top of the connecting shaft 2062 is fixedly connected to the bottom of the gear 201. A fixing plate 10 is provided on the outside of the support plate 1. The top of the fixing plate 10 is fixedly connected to the bottom of the motor 2061. The fixing plate 10 is used to support and fix the motor 2061. An inclined plate 11 is provided on the top of the support plate 1. The inclined plate 11 is fixedly connected to the outside of the movable plate 205.

[0040] Specifically, when the bearing needle rollers are moved, the motor 2061 is started, and the kinetic energy generated is transmitted through the connecting shaft 2062, driving the gear 201 to rotate. The gear 201 meshes with the rack 202, so that the rotational motion of the gear 201 is converted into the linear motion of the rack 202. The movement of the rack 202 drives the L-shaped rod 1 203 and L-shaped rod 204 to move, which in turn causes the movable plate 205 fixed on the two rods to move. During the sliding process, the movable plate 205 contacts the bearing needle rollers and moves the scattered bearing needle rollers in an orderly manner, thereby tidying up the bearing needle rollers. On the outside of the support plate 1, there is a fixed plate 10, the top of which is fixedly connected to the bottom of the motor 2061. The function of the fixed plate 10 is to provide support and fixation for the motor 2061. The top of the support plate 1 is equipped with a sloping plate 11, which is fixedly connected to the outside of the movable plate 205.

[0041] Reference Figure 2 , Figure 3 and Figure 5The screening mechanism 3 includes a needle box 301, which is located on the top of the support plate 1. A connecting rod 302 is located on the rear bottom side of the needle box 301. A vibrating funnel 303 is located on the bottom of the needle box 301. A needle feeding tube 304 is located on the right side of the bottom of the needle box 301. A needle dispensing box 305 is installed on the top of the support plate 1. A needle dispensing disc 306 is installed on the top of the needle dispensing box 305. Multiple needle grooves 307 are equidistantly opened on the outer side of the needle dispensing disc 306. A height limiting block 308 is located on the rear top side of the needle dispensing box 305. A needle outlet tube 309 is located on the right side of the height limiting block 308. A sliding groove 8 is located on the outer side of the support plate 1. The sliding groove 8 is located on the front top side of the needle box 301. A limit block 9 is slidably connected to the inner wall of the sliding groove 8. The top of the limit block 9 is fixedly connected to the bottom of the rack 202 to limit the movement.

[0042] Specifically, the operator pours the needle rollers into the needle loading box 301. The needle rollers slowly descend from the top of the needle loading box 301 to the vibrating funnel 303 at the bottom. The vibration function of the vibrating funnel 303 causes the needle rollers to pass sequentially through the needle delivery tube 304, and finally be delivered to the needle distribution plate 306 at the top of the needle distribution box 305. The needle distribution plate 306 rotates counterclockwise, and the needle grooves 307, which are equidistantly arranged on its outer edge, rotate at a fixed angle each time. When the needle grooves 307 carrying the needle rollers pass the height limiting block 308, the height limiting block 308 is trapezoidal, and its inclined surface contacts the needle roller, pushing the needle roller downward to ensure that the needle roller maintains a suitable height. During the rotation of the needle distribution plate 306, each box at the bottom is provided with a needle hole that matches the thickness of the needle roller, and the size of the needle hole is differentiated by a difference of micrometers. When the roller passes through the needle hole that is adapted to its own size, it will fall into the corresponding needle box below, thereby achieving precise screening of the roller thickness. The outer side of the support plate 1 is provided with a sliding groove 8, which is located on the top front side of the needle box 301. The inner wall of the sliding groove 8 is slidably engaged with the limiting block 9. The top of the limiting block 9 is fixedly connected to the bottom of the rack 202 to achieve the limiting function.

[0043] Reference Figure 1 and Figure 2 Corner guards 4 are provided at the four corners of the top of the bearing plate 1. Screws 5 are threaded to the outside of the corner guards 4. The corner guards 4 are fixed by the screws 5 to provide protection. A support rod 6 is fixedly connected to the left side of the rear top of the bearing plate 1. A control box 7 is provided on the top of the support rod 6 for controlling the whole.

[0044] Specifically, corner guards 4 are provided at the four corners of the top of the support plate 1. These corner guards 4 are connected to screws 5 by the outer threads and fixed with screws 5 to achieve the protection function. The top rear left end of the support plate 1 is fixedly connected to the support rod 6. The top of the support rod 6 is provided with a control box 7 for controlling the whole.

[0045] Working principle: When the bearing needle rollers are moved, the motor 2061 is started. The kinetic energy output by the motor drives the gear 201 to rotate through the connecting shaft 2062. Since the gear 201 meshes with the rack 202, the rotational motion of the gear 201 is converted into the motion of the rack 202. The rack 202 drives the L-shaped rod 1 203 and L-shaped rod 204 to move, which in turn drives the moving plate 205 fixed on the two to move. During the sliding process, the moving plate 205 contacts the bearing needle rollers and moves the messy bearing needle rollers, thereby processing the bearing needle rollers.

[0046] The operator pours the needle rollers into the needle box 301. The needle rollers slowly fall from the top of the needle box 301 into the vibrating funnel 303 at the bottom. Through the vibration of the vibrating funnel 303, the needle rollers pass through the needle delivery tube 304 in an orderly manner and are finally delivered to the needle distribution plate 306 at the top of the needle distribution box 305. The needle distribution plate 306 rotates counterclockwise. The needle grooves 307, which are equally spaced on the outer side, rotate by a fixed angle each time. When the needle grooves 307 carrying the needle rollers pass the height limiting block 308, the height limiting block 308 is trapezoidal, and its inclined surface abuts against the needle roller, pushing the needle roller downward to ensure that the needle roller maintains a suitable height. During the rotation of the needle distribution plate 306, each box at the bottom is provided with a corresponding size of needle hole. The size of the needle hole is one micrometer apart. When the needle roller passes through the needle hole that matches its own thickness, it will fall into the corresponding needle box below, thus completing the screening of the thickness of the needle roller.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
