Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing steel ball feeding, and in particular to a matrix-type high-precision automatic arrangement and feeding device for bearing steel balls. Background Technology
[0002] As the core component of rolling bearings, the machining accuracy and surface quality of bearing steel balls directly affect the bearing's operating accuracy, load-bearing capacity, and service life. In the precision bearing manufacturing process, bearing steel balls need to undergo dimensional inspection and screening before being arranged and loaded. However, most existing loading devices use simple conveyor belt structures, but conventional conveyor belts lack effective limiting mechanisms, which makes it easy for bearing steel balls to roll back and forth during the conveying process. This results in inaccurate loading positions and uneven arrangement, seriously affecting the loading efficiency and stability of automated production lines, and making it difficult to meet the process requirements of step-by-step loading of precision steel balls in modern bearing manufacturing.
[0003] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a high-precision automatic arrangement and feeding device for bearing steel balls in a matrix to solve the aforementioned technical defects.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A high-precision automatic arrangement and feeding device for bearing steel balls in a matrix configuration includes a steel ball box. Below the steel ball box is a feeding hopper that is fixedly connected and internally connected. One side of the feeding hopper is fixedly connected to a stepper motor via bolts. The drive shaft of the stepper motor extends into the feeding hopper and is fixedly connected to a feeding disc.
[0007] The steel ball box is also provided with a screening and feeding mechanism on one side. The screening and feeding mechanism includes a housing. A conveyor housing is fixedly connected below the housing. A mounting frame is fixedly installed above the conveyor housing by bolts. An electric push rod is fixedly installed above the mounting frame by bolts.
[0008] Preferably, the outer side of the feeding tray is provided with axially distributed placement grooves, one end of the feeding hopper is provided with a fixedly connected slide, and one end of the slide is provided with a fixedly connected feeding cylinder.
[0009] Preferably, the upper part of the housing is provided with a screening section 1, a screening section 2 and a feeding trough that are fixedly connected. Below the screening section 1 is a feeding frame 1 that is fixedly connected. Below the feeding trough is a feeding frame 2 that is fixedly connected. Below the screening section 2 is a feeding plate that is fixedly connected. The width of the screening trough in the screening section 1 is smaller than the width of the screening trough in the screening section 2. The width of the screening trough in the feeding trough is larger than the width of the screening trough in the screening section 2.
[0010] Preferably, the drive shaft of the first electric push rod is provided with a fixedly connected baffle at its end, the side of the conveyor housing is provided with a fixedly connected second electric push rod, the drive shaft of the second electric push rod passes through the conveyor housing and is provided with a fixedly connected push plate, and the side of the conveyor housing is also provided with a fixedly connected second stepper motor by bolts.
[0011] Preferably, the conveyor housing is symmetrically provided with rotatably connected rollers, one of which has a shaft at one end passing through the conveyor housing and is provided with a fixedly connected spur gear, and the outer side of the roller is fitted with a rotatably connected conveyor belt.
[0012] Preferably, the outer side of the conveyor belt is provided with an array of placement slots, and the outer side of the conveyor belt between the transversely distributed placement slots is provided with a fixedly connected partition plate. The drive shaft of the second stepper motor passes through the conveyor housing and is provided with a fixedly connected incomplete gear. The incomplete gear meshes intermittently with the spur gear.
[0013] The beneficial effects of this utility model are as follows:
[0014] This invention achieves automatic screening by placing bearing steel balls inside a ball box and using a stepper motor to rotate a feeding disc, which sequentially transports the steel balls to a slide and a feeding cylinder, ultimately dropping them onto the top of the housing. The steel balls first pass through a screening section; smaller balls fall into a feeding frame, while qualified balls pass through a screening section and fall onto a feeding plate. Larger balls enter the feeding frame via a feeding trough, thus achieving automatic screening. Qualified balls fall onto a baffle side via the feeding plate, and an electric push rod pushes a push plate to arrange the balls sequentially into a placement slot. After one row is arranged, the electric push rod raises the baffle, and the stepper motor, through incomplete gears and spur gears, drives the conveyor belt to move intermittently, achieving array conveying of the steel balls. This results in automated screening, precise arrangement, and efficient conveying of bearing steel balls, improving production efficiency and sorting accuracy. Attached Figure Description

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.
[0023] Example 1:
[0024] Please see Figure 1 - Figure 5 As shown, this utility model is a high-precision automatic arrangement and feeding device for bearing steel balls in a matrix manner. It includes a steel ball box 1, and a feeding hopper 11 is fixedly connected and internally communicated below the steel ball box 1. A stepper motor 12 is fixedly connected to one side of the feeding hopper 11 by bolts. The drive shaft of the stepper motor 12 extends into the feeding hopper 11 and is fixedly connected to a feeding disc 13. An axially distributed placement groove is opened on the outer side of the feeding disc 13. The placement groove is used to hold bearing steel balls for easy conveying. A slide 14 is fixedly connected to one end of the feeding hopper 11, and a feeding cylinder 15 is fixedly connected to one end of the slide 14.
[0025] A screening and feeding mechanism 2 is also provided on one side of the steel ball box 1. The screening and feeding mechanism 2 includes a housing 21. A conveyor housing 28 is fixedly connected to the lower part of the housing 21. A screening section 1 22, a screening section 23 and a discharge chute 24 are fixedly connected to the upper part of the housing 21. A discharge frame 1 25 is fixedly connected to the lower part of the screening section 1 22. A discharge frame 26 is fixedly connected to the lower part of the discharge chute 24. A discharge plate 27 is fixedly connected to the lower part of the screening section 23.
[0026] The width of the screening trough in screening section 1 22 is smaller than the width of the screening trough in screening section 23, and the width of the screening trough in the feeding trough 24 is larger than the width of the screening trough in screening section 23. When the bearing steel balls fall through one end of screening section 1 22, they first pass through screening section 1 22. At this time, the smaller steel balls fall into the feeding frame 1 25, the bearing steel balls of suitable size fall through the feeding plate 27 below screening section 23, and the larger bearing steel balls fall through the feeding frame 26 below the feeding trough 24, thereby realizing the screening operation of bearing steel balls.
[0027] A mounting bracket 29 is bolted to the top of the conveyor housing 28. An electric push rod 30 is bolted to the top of the mounting bracket 29. A baffle 31 is fixedly connected to the end of the drive shaft of the electric push rod 30. An electric push rod 32 is fixedly connected to one side of the conveyor housing 28. A push plate 33 is fixedly connected to the drive shaft of the electric push rod 32 after passing through the conveyor housing 28. A stepper motor 34 is also fixedly connected to one side of the conveyor housing 28 by bolts.
[0028] Inside the conveyor housing 28, there are symmetrically arranged rotatably connected rollers. One end of one roller has a shaft that passes through the conveyor housing 28 and is connected to a fixed spur gear 36. A rotatably connected conveyor belt 37 is fitted on the outside of the roller. An array of placement grooves 38 are opened on the outside of the conveyor belt 37. A fixedly connected partition plate 39 is provided on the outside of the conveyor belt 37 between the transversely distributed placement grooves 38. The drive shaft of the stepper motor 34 passes through the conveyor housing 28 and is connected to a fixed incomplete gear 35. The incomplete gear 35 and the spur gear 36 mesh intermittently.
[0029] The working process and principle of this utility model are as follows:
[0030] In use, the bearing steel balls are first placed in the steel ball box 1, and then the stepper motor 12 is started. The stepper motor 12 drives the feeding plate 13 to rotate, thereby conveying the bearing steel balls in the steel ball box 1 to the slide 14 one by one. After passing through the slide 14 and the feeding cylinder 15, the bearing steel balls slide down into the upper part of the housing 21. The bearing steel balls first pass through the screening section 22 above the housing 21. At this time, the smaller steel balls fall into the feeding frame 25. The bearing steel balls of appropriate size fall through the feeding plate 27 below the screening section 23. The larger bearing steel balls fall through the feeding frame 26 below the feeding trough 24, thereby realizing the screening operation of the bearing steel balls.
[0031] The appropriately sized bearing steel balls fall through the feed plate 27 into one side of the baffle 31. At this time, the electric push rod 32 is activated to drive the push plate 33 to push the bearing steel balls into the farthest placement slot 38. The bearing steel balls that fall next are pushed into the placement slot 38 in sequence from far to near until a row of bearing steel balls is arranged. At this time, the electric push rod 30 is activated to drive the baffle 31 to move upward. The stepper motor 34 is activated to drive the incomplete gear 35 to rotate one revolution. When the incomplete gear 35 rotates, it drives the spur gear 36 to rotate intermittently, thereby driving the conveyor belt 37 to transport the bearing steel balls on it in an array.
