Description

Technical Field

[0001] This utility model relates to the field of shaft sleeve processing technology, and in particular, to a bearing vibration feeding device. Background Technology

[0002] In the production of bushing-type parts, it is often necessary to create annular grooves on the outer wall of the workpiece. These grooves serve various purposes, such as for inserting sealing rings, snap rings, or retaining rings, and also as storage spaces for lubricating oil to reduce friction. Traditional manufacturing methods involve creating these grooves using machine tools such as lathes, grinders, or milling machines. However, these methods require clamping each workpiece individually, resulting in low efficiency and unsuitability for mass production.

[0003] People gradually discovered that the thread rolling machine 17 could be used to create annular grooves on bushing-type parts, simply by replacing the threads on the thread rolling plate with protrusions. The protrusions press against the workpiece, and the workpiece rotates during the rolling motion, thus creating the annular groove.

[0004] Automatic feeding of materials into the wire rolling machine 17 is typically achieved via a vibratory feeder. For example... Figure 1 The example shown is a bushing-type part with two axially different diameter sections. The process requires an annular groove 16 to be made on the outer wall of the smaller diameter section. During the feeding and screening process, the current practice is to adjust the workpiece's orientation to the downward direction of the larger diameter using a sorting mechanism on a vibrating plate. However, when the smaller diameter is downward, the workpiece's center of gravity is unstable and it will tip over and re-enter the plate.

[0005] However, thread rolling machines require the bottom end of the workpiece to be rolled, which necessitates that the workpiece enter the thread rolling station with the smaller diameter facing down. Current methods involve installing a spiral section at the front end of the discharge track, which drives the workpiece passing through the spiral section to rotate at both ends. However, this increases the overall length of the discharge track, and if the spiral angle is not suitable, it can easily lead to material jamming. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a bearing vibration feeding device.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A bearing vibration feeding device includes a vibratory feeder body, the vibratory feeder body includes a hopper, a conveying track is provided on the inner wall of the hopper, a sorting mechanism is also provided in the hopper, a flipping mechanism is provided at the rear end of the sorting mechanism in the hopper, and a receiving channel is provided at the rear end of the flipping mechanism in the hopper. The flipping mechanism is adapted to drive both ends of the workpiece to flip, so that the small diameter part of the workpiece is inserted into the receiving channel.

[0009] Preferably, the sorting mechanism includes a rotatable swing arm, and the material conveying track is provided with a retaining flange at the rear end of the swing arm.

[0010] Preferably, the flipping mechanism includes a rotatable drive rod, the end of which is provided with a clamping member, the clamping member being adapted to fix the workpiece at the receiving position and then release the workpiece again at the feeding position.

[0011] Preferably, the clamping member includes opposing clamping plates, the distance between the two clamping plates is greater than the width of the receiving channel, and the inner sidewall of the clamping plate is provided with a fixing member for clamping the outer wall of the workpiece.

[0012] Preferably, the fixing element includes an electromagnet or a negative pressure adsorption device.

[0013] Preferably, the fastener includes a spring-loaded buckle, and a pressure plate is rotatably disposed above the discharge port of the conveying track inside the hopper. A torsion spring is connected to the pressure plate, and the torsion spring is adapted to allow the pressure plate to deflect to allow the workpiece to pass through after being subjected to a threshold pressure.

[0014] Preferably, the receiving channel is defined by two spaced-apart receiving rods.

[0015] The beneficial effects of this invention are as follows: Under the action of vibration, the workpiece in the hopper moves along the conveying track. During this process, the sorting mechanism forces the workpiece with its larger diameter facing downwards to remain in the conveying track, while the workpiece with its smaller diameter facing downwards falls back into the hopper. Subsequently, the flipping mechanism flips both ends of the workpiece and feeds it into the receiving channel, which connects to the relatively straight discharge track until the workpiece is delivered to the thread rolling station. Compared with the prior art, this invention achieves the flipping of the workpiece through the flipping mechanism, thereby shortening the length of the discharge track and reducing the likelihood of the workpiece getting stuck in the discharge track.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 2 to 5 As shown, a bearing vibration feeding device includes a vibratory feeder body 1, which may include a hopper 2 and a vibration source disposed at the bottom of the hopper 2. The structure and principle of the vibration source, as well as the basic structure of the hopper 2, are existing technologies and will not be described in detail in this utility model.

[0024] For example, a conveying track 3 may be spirally arranged on the inner wall of the hopper 2. Its basic structure consists of conveying plates arranged on the inner wall of the hopper 2, or it may be formed by the stepped structure of the hopper 2 itself. Under the action of a vibration source, the workpiece will move along the conveying track 3, and a sorting mechanism 4 is also provided inside the hopper 2. This sorting mechanism 4 is used to sort the workpieces into a position with the larger diameter facing downwards. The sorting mechanism 4 capable of achieving this function has been disclosed in the prior art.

[0025] In this preferred embodiment, a lifting rod may be provided on the conveying track 3, along which the workpiece will be gradually lifted. At the end of the lifting rod, a rotatable swing rod 7 is provided on the hopper 2. More specifically, the lifting rod is also adapted to gradually extend into the hopper 2, at which point the distance between the lifting rod and the inner wall of the hopper 2 gradually increases. When the workpiece comes into contact with the swing rod 7, the swing rod 7 will exert an abutment force on the end of the workpiece, which will cause the workpiece to more easily flip over and fall into the conveying track 3 below with one end facing down.

[0026] For example, the lower conveying track 3 is provided with a retaining flange 8 at the rear end of the swing rod 7. This allows the conveying track 3 to be designed with a certain tilt angle, thereby giving the workpiece a tendency to tilt inward. However, the workpiece with the larger diameter facing down will abut against the retaining flange 8 and will not easily tilt. The workpiece with the smaller diameter facing down will eventually fall back into the hopper 2 because it does not abut against the flange and its center of gravity is unstable.

[0027] It should be recognized that the term "back end" in this article refers to the front and back as defined along the conveying direction of the material conveying track 3.

[0028] like Figure 3 , Figure 4 As shown, a flipping mechanism 5 is located at the rear end of the sorting mechanism 4 within the hopper 2, and a receiving channel 6 is also located at the rear end of the flipping mechanism 5. For example, the receiving channel 6 can be defined by two spaced-apart receiving rods 15. When a workpiece with its large diameter facing downwards arrives at the discharge port of the conveying track 3, the flipping mechanism 5 can drive both ends of the workpiece to flip, causing the small diameter portion of the workpiece to be inserted into the receiving channel 6. Subsequently, under the action of vibration, the workpiece with its small diameter facing downwards can move into the relatively straight discharge track until it reaches the thread rolling station.

[0029] In some embodiments, the flipping mechanism 5 includes a rotatable drive rod 9, which can be rotated by a motor. The end of the drive rod 9 is also provided with a clamping member 10, which is adapted to be fixed to the workpiece at the receiving position (i.e., at the outlet of the feed track 3) and then released again at the feeding position (i.e., at the inlet of the receiving channel 6).

[0030] For example, the clamping plate may include two opposing clamping plates 11, the distance between the two clamping plates 11 being approximately equal to the diameter of the major diameter portion of the workpiece, and the distance between the two clamping plates 11 being greater than the width of the receiving channel 6. In addition, a fixing member 12 for clamping the outer wall of the workpiece is provided on the inner wall of the clamping plate 11.

[0031] When the drive rod 9 rotates, it causes the clamping plate 11 to align with the large-diameter portion of the workpiece at the receiving position, and then the fixing member 12 secures the workpiece. Subsequently, the drive rod 9 drives the clamping plate 11 to rotate towards the feeding position until the small-diameter portion of the workpiece is engaged in the receiving channel 6. At this point, the fixing member 12 releases the workpiece. As the drive rod 9 continues to rotate, the two clamping plates 11 pass through the outside of the receiving channel 6 without easily interfering with the workpiece.

[0032] For example, the fastener 12 may include an electromagnet or a negative pressure adsorption device, both of which are common in non-standard designs. Their fastening principles will not be elaborated in this example.

[0033] Alternatively, the fastener 12 may include a spring-loaded buckle 13, and a pressure plate 14 is rotatably disposed above the discharge port of the conveying track 3 inside the hopper 2, and a torsion spring is connected to the pressure plate 14, which is adapted to allow the pressure plate 14 to deflect under the action of a threshold pressure.

[0034] Therefore, when the drive rod 9 rotates, it causes the clamping plate 11 to align with the large-diameter portion of the workpiece at the receiving position. During this process, the latch 13 pushes the workpiece upward against the pressure plate 14. Subsequently, the latch 13 springs and engages in the annular groove 16 on the outer wall of the large-diameter portion of the workpiece. This annular groove 16 can be machined by a lathe or other machine tool in the previous process of the workpiece. As the drive rod 9 continues to rotate, the pressure plate 14 rotates, allowing the workpiece held by the clamping plate to rotate to the feeding position. At the feeding position, the workpiece abuts against the receiving channel 6, and the latch 13 is forced to disengage from the annular groove 16, thereby achieving automatic release of the workpiece.

[0035] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
