Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, and in particular to a rotary bearing automatic unloading machine. Background Technology

[0002] In the field of CNC machining of bearing rings, with the development of automation technology, various automatic unloading schemes are now widely used to improve production efficiency. A common method is that, as disclosed in patent document CN222327479U, the bearing rings are discharged via a track after machining, and a pusher device is used to automatically unload the bearing rings.

[0003] In practical applications of the aforementioned patent documents, the inventors discovered that the storage capacity for bearing rings is limited, and the CNC machining speed of the bearing rings is extremely fast, averaging 10-20 seconds per bearing ring. Of course, this machining time depends on the specific machining process, such as machining only the bearing ring end face, outer diameter, or inner diameter. Therefore, the machining efficiency is very high, requiring someone to be constantly present at the equipment to remove the bearing rings. While material unloading is automated, production still requires human supervision. Of course, if cost is not a concern, a three-axis robot can be used to replace manual labor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rotary bearing automatic unloading machine, which solves the technical problem that existing bearing unloading equipment has a limited number of temporarily stored bearing rings, still requiring frequent manual removal of bearing rings.

[0005] According to an embodiment of the present invention, a rotary bearing automatic unloading machine includes an unloading mechanism and a storage tray device disposed on one side of the unloading mechanism, wherein the unloading mechanism is inclined toward the storage tray device. The storage tray device includes a drive mechanism and a turntable that is connected to the drive mechanism. Storage shafts are evenly distributed around the turntable. A pushing mechanism is provided on the side of the storage shaft away from the turntable. The pushing mechanism is connected to a feeding mechanism on one side. The pushing mechanism can move along the axis of the storage shaft and in the vertical direction.

[0006] The technical principle of this utility model is as follows: After the bearing ring is processed, it rolls down along the feeding mechanism and enters the pushing mechanism. Here, the pushing mechanism first pushes the bearing onto the storage shaft, that is, moves along the axis of the storage shaft, and then moves downward, so that the pushing mechanism is separated from the bearing ring. Then the pushing mechanism first returns to its original position horizontally, and finally rises back to its original position to wait for the next bearing ring.

[0007] When a storage shaft is full of bearing rings, the drive mechanism drives the turntable to rotate, so that the next storage shaft without bearing rings moves to the alignment and feeding mechanism to continue receiving bearing rings.

[0008] This application typically sets up at least 4 storage shafts, which can basically meet the bearing storage needs of about half an hour to one hour. That is, the operator only needs to conduct regular inspections every half hour or one hour, and remove the bearing rings for storage during the inspection.

[0009] Compared with the prior art, this utility model has the following beneficial effects: by forming a three-dimensional storage space by evenly distributing storage shafts around the turntable, more bearing rings can be stored. Then, in conjunction with the pushing mechanism and the unloading mechanism, it solves the technical problem in the existing bearing discharge equipment that the number of temporarily stored bearing rings is limited and that the bearing rings still need to be frequently removed manually.

[0010] Furthermore, the feeding mechanism includes an inclined base frame and two side plates mounted on the inclined base frame. One side plate has a protruding flange on the side away from the feeding mechanism, and the other side plate has an inclined flange on the side away from the feeding mechanism.

[0011] Furthermore, the feeding mechanism is provided with a conveying mechanism on the side away from the pushing mechanism, the protruding flange is connected to the upper surface of the conveying mechanism, and the inclined flange is aligned with one side of the conveying mechanism.

[0012] Furthermore, the inclined base frame has protruding edges on both sides of the top, and an adjustment mechanism is provided between the two protruding edges and the two side plates. The adjustment mechanism includes studs fixed on the side plates and inner and outer nuts installed on the studs. The studs pass through the protruding edges, and the inner and outer nuts are respectively installed on both sides of the protruding edges.

[0013] The spacing between the two side plates is adjusted by an adjustment mechanism to accommodate bearing rings of different thicknesses.

[0014] Furthermore, the top of the feeding mechanism is provided with two sets of material-blocking cylinders at intervals. The two sets of material-blocking cylinders are arranged along the length direction of the feeding mechanism, and the piston rod of the material-blocking cylinder is provided with a stop block at the top.

[0015] Furthermore, the pushing mechanism includes a lifting cylinder, a pushing cylinder mounted on the piston rod of the lifting cylinder, and a bearing storage position mounted on the piston rod of the pushing cylinder.

[0016] Furthermore, the bearing temporary storage position includes a U-shaped plate and a stop bar disposed at one end of the U-shaped plate away from the feeding mechanism. The other end of the U-shaped plate is connected to the feeding mechanism. The U-shaped plate is provided with a clearance groove, which is aligned with the storage shaft.

[0017] Furthermore, the U-shaped plate has horizontally arranged elongated holes on both sides, and the two ends of the baffle rod are respectively installed at the two elongated holes.

[0018] Furthermore, the driving mechanism is a stepper motor, and an infrared sensor is provided near the turntable. Attached Figure Description

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] like Figure 1The rotary bearing automatic unloading machine shown includes an unloading mechanism 1 and a storage tray device 2 located on one side of the unloading mechanism 1. The unloading mechanism 1 is inclined to the storage tray device 2. Specifically, a conveying mechanism 3 is provided on the side of the unloading mechanism 1 away from the storage tray device 2. The conveying mechanism 3 is a synchronous belt device, which horizontally transports the processed bearing rings to the unloading mechanism 1.

[0029] like Figure 2-4 As shown, the unloading mechanism 1 includes an inclined base frame 11 and two side plates 12 mounted on the inclined base frame 11. One side plate 12 has a raised flange 121 integrally formed on the side away from the pushing mechanism 4, and the other side plate 12 has an inclined flange 122 integrally formed on the side away from the pushing mechanism 4. Both the raised flange 121 and the inclined flange 122 need to be naturally transitioned to the side plate 12 by an arc. The raised flange 121 is connected to the upper surface of the conveying mechanism 3, and the inclined flange 122 is aligned with one side of the conveying mechanism 3. That is, the bearing ring on the conveying mechanism 3 will first be supported on the raised flange 121, and then slide into the space between the two side plates 12.

[0030] like Figure 2-3 As shown, the inclined base frame 11 has integrally formed protruding edges 111 on both sides of its top. An adjustment mechanism 13 is provided between the two protruding edges 111 and the two side plates 12. The specific adjustment mechanism 13 includes studs 131 fixed on the side plates 12 and inner nuts 132 and outer nuts 133 installed on the studs 131. The studs 131 pass through the protruding edges 111, and the inner nuts 132 and outer nuts 133 are respectively installed on both sides of the protruding edges 111. Thus, the operator can adjust the thickness according to the bearing ring. If the thickness needs to be increased, the outer nut 133 is rotated outward until the required thickness distance is reached. Then, the side plates 12 and studs 131 are moved so that the outer nut 133 is tightly pressed against the protrusion again. Finally, the inner nut 132 is rotated to press tightly against the protrusion again, thereby fixing the side plates 12.

[0031] like Figure 2-4 As shown, two sets of baffle cylinders 14 are installed at intervals on the top of the feeding mechanism 1. The two sets of baffle cylinders 14 are arranged along the length of the feeding mechanism 1. A stop block 141 is fixed on the top of the piston rod of the baffle cylinder 14, so that the bearing ring can be temporarily stored between the two sets of baffle cylinders 14. A bearing sensing switch 142 is provided between the two sets of baffle cylinders 14 in the feeding mechanism 1 to sense the bearing ring.

[0032] like Figure 1 , 5 As shown, the storage tray device 2 includes a drive mechanism 21 and a turntable 22 that is connected to the drive mechanism 21. Storage shafts 221 are evenly distributed around the turntable 22. A pushing mechanism 4 is provided on the side of the storage shaft 221 away from the turntable 22. The pushing mechanism 4 is connected to the unloading mechanism 1 on one side. The pushing mechanism 4 can move along the axial direction of the storage shaft 221 and the vertical direction.

[0033] The specific drive mechanism 21 is a stepper motor. An infrared sensor 222 is provided near the turntable 22. The infrared sensor 222 is used to determine whether the storage shaft 221 is fully loaded with bearing rings. If it is fully loaded, the CNC system controls the stepper motor to rotate by an angle so that the next storage shaft 221 moves to the side of the corresponding pusher mechanism 4.

[0034] like Figure 5-6 As shown, the pushing mechanism 4 includes a lifting cylinder 41, a pushing cylinder 42 mounted on the piston rod of the lifting cylinder 41, and a bearing storage position mounted on the piston rod of the pushing cylinder 42 for temporarily storing bearing rings. A weight sensing switch 45 is provided on the bearing storage position for sensing the bearing rings.

[0035] like Figure 5-7 As shown, the bearing temporary storage position includes a U-shaped plate 43 and a baffle rod 44 disposed at one end of the U-shaped plate 43 away from the feeding mechanism 1. The other end of the U-shaped plate 43 is connected to the feeding mechanism 1. The U-shaped plate 43 is provided with a relief groove 431, which is aligned with the storage shaft 221. Specifically, the U-shaped plate 43 has horizontally arranged elongated holes 432 on both sides. The two ends of the baffle rod 44 are respectively installed at the two elongated holes 432. The position of the baffle rod 44 can be adjusted according to the actual bearing ring diameter so that the baffle rod 44 can more accurately block the bearing ring.

[0036] The bearing sensing switch 142 and the weight sensing switch 45 control the solenoid valve, which changes the air path to allow the material blocking cylinder 14, the lifting cylinder 41 and the pushing cylinder 42 to retract and extend.

[0037] The specific workflow is as follows; In the initial stage, the material blocking cylinder 14 near the material storage tray device 2 is in the extended state, and the other material blocking cylinder 14 is in the retracted state.

[0038] When the bearing ring rolls into the side of the baffle cylinder 14, it will be sensed by the bearing sensing switch 142. At this time, another baffle cylinder 14 will extend to block the subsequent bearing ring from entering, while the baffle cylinder 14 near the storage tray device 2 will retract to allow the bearing ring to roll into the bearing temporary storage position.

[0039] At this point, the weight sensor switch 45 detects the bearing ring, causing the pusher cylinder 42 to push the bearing onto the storage shaft 221. Then, the lifting cylinder 41 descends, causing the bearing ring to disengage from its temporary storage position. Next, the pusher cylinder 42 retracts, and finally, the lifting cylinder 41 rises. Simultaneously, the two stop cylinders 14 return to their initial positions, facilitating the entry of subsequent bearing rings.

[0040] The above workflow can be controlled by a CNC system in conjunction with a pneumatic circuit, or by an electrical circuit in conjunction with a pneumatic circuit.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
