The magnetic ring is transported to the magnetic ring pressing process through the pallet line, and the automatic oil spraying device for the inner hole of the magnetic ring is used to spray oil on the inner hole of the magnetic ring during the transportation process of the magnetic ring to facilitate pressing.

[0035] As attached Figure 1 and attached Figure 2As shown, the automatic oil spraying device for the inner hole of the magnetic ring includes a frame 1, a linear slide 2 and an oil spraying station 4 arranged on the frame; the linear slide 2 is arranged on one side of the pallet line 10, and a clamping claw assembly 3 is provided on the linear slide 2 for grabbing the magnetic ring placed on the pallet on the pallet line; the oil spraying station 4 is arranged relative to the linear slide 2 for spraying oil into the inner hole of the magnetic ring. Specifically, the clamping claw assembly 3 is fixed on the slide seat of the linear slide 2, and the clamping claw assembly can be controlled to move left and right by the linear slide, so that after the clamping claw assembly grabs the magnetic ring, it is transferred from the pallet of the pallet line to the oil spraying station for oil spraying, and after the oil spraying, it is transferred from the oil spraying station to the pallet of the pallet line. Preferably, the clamp assembly 3 in this embodiment includes a slide cylinder 3.1 and a clamp 3.2 arranged on the slide cylinder 3.1, and the clamp 3.2 is used to clamp the magnetic ring 30, preferably a Schunk air clamp; the slide cylinder 3.1 controls the up and down movement of the clamp 3.2, realizing the movement of the clamp to grasp downward and reset after grasping.

[0036] Preferably, as attached Figure 1 and attached Figure 3 As shown, the oil injection station 4 includes a sprayer 4.1, a nozzle 4.2, a linear cylinder 4.3 and an oil nozzle 4.4. The linear cylinder 4.3 is fixedly mounted on the frame 1 through an oil injection bracket, the sprayer 4.1 is fixedly mounted on the push plate of the linear cylinder 4.3 through a sprayer bracket, the nozzle 4.2 is arranged at the outlet of the sprayer 4.1, and the oil nozzle 4.4 is arranged on the oil injection bracket opposite to the nozzle 4.2. This design allows the magnetic ring to be placed on the oil nozzle, and the linear cylinder can be used to drive the nozzle downward into the inner ring of the magnetic ring to spray oil on the magnetic ring. The oil nozzle can also collect oil to prevent oil from dripping and polluting the environment.

[0037] Preferably, the sprayer 4.1 is connected to an oil supply pot (not shown in the figure) via an oil pipe, and the oil supply pot is used to supply oil to the sprayer; the oil nozzle 4.4 is connected to an oil return pot 4.5 via an oil return pipe, which is used to recover the oil collected by the oil nozzle, and the oil return pot is arranged on the frame.

[0038] Preferably, as attached Figure 4 As shown, the outer diameter of the oil receiving nozzle 4.4 matches the inner diameter of the stepped hole 30.1 at the bottom of the magnetic ring 30, which facilitates the positioning of the magnetic ring and ensures that the magnetic ring has a relatively stable position during the oil injection process.

[0039] During the implementation of this embodiment, when the pallet line moves the pallet to a position where the magnetic ring on it faces the clamping jaws, the pallet line can be controlled to stop, and the magnetic ring is clamped by the linear slide and the clamping jaw assembly, and transferred to the oil receiving nozzle. Then the linear cylinder is actuated to allow the nozzle to enter the inner hole of the magnetic ring. At this time, the sprayer works to spray oil into the inner hole of the magnetic ring. After the oil spraying is completed, the linear cylinder is reset, and the clamping jaw assembly clamps the magnetic ring and transfers it to the pallet and then resets. Next, the pallet line is started and the above steps are repeated.

[0040] Embodiment 2

[0041] Based on the first embodiment, as shown in the attached Figure 1 and attached Figure 5 As shown, this embodiment is further provided with a lifting assembly 5, which is arranged on the frame 1 in the middle of the pallet line 10 and is used to lift the pallet before the clamping claw assembly clamps the magnetic ring.

[0042] Preferably, as attached Figure 5 As shown, the lifting assembly 5 includes a lifting plate 5.1, a lifting cylinder 5.2 and a linear bearing 5.3, wherein the lifting cylinder 5.2 is fixedly mounted on the frame 1, the lifting plate 5.1 is fixedly mounted on the top rod of the lifting cylinder 5.2, the guide shaft of the linear bearing 5.3 is arranged at the bottom of the lifting plate 5.1, and the bearing sleeve thereof is arranged on the frame 1. The lifting assembly can lift the lifting plate to a certain height by the lifting cylinder.

[0043] Preferably, the lifting plate 5.1 is provided with a plurality of positioning pins 5.1.1 corresponding to the positioning holes of the pallet 20. After the lifting plate is lifted, the positioning pins are inserted into the positioning holes of the pallet, so that the pallet has a stable position after lifting. Preferably, the positioning pins include two arranged diagonally.

[0044] During the specific implementation of this embodiment, when the pallet line moves the pallet to a position where the magnetic ring on it faces the clamping claw, the pallet line can be controlled to stop. At this time, the lifting assembly lifts the pallet to make it separate from the pallet line, and then the magnetic ring is clamped by the linear slide and the clamping claw assembly, and transferred to the oil receiving nozzle. Then the linear cylinder is actuated to make the nozzle enter the inner hole of the magnetic ring. At this time, the sprayer works to spray oil into the inner hole of the magnetic ring. After the oil spraying is completed, the linear cylinder is reset, the clamping claw assembly clamps the magnetic ring and transfers it to the pallet and resets it. Then the lifting assembly is reset, and then the pallet line is started, and the above steps are repeated. This embodiment can reduce the stroke of the slide cylinder.

[0045] Embodiment 3

[0046] Based on the second embodiment, as shown in the attached Figure 1As shown, in this embodiment, a photoelectric sensor 6 is further provided on the side of the pallet line 10 away from the spray station 4 and facing the spray station 4, for detecting whether there is a magnetic ring 30 on the lifted pallet 20. This design can achieve that when it is detected that there is no magnetic ring on the pallet, the clamping claw assembly does not move, and the pallet continues to be transported downward, preventing the equipment from making useless movements.

[0047] Embodiment 4

[0048] Based on the third embodiment, as shown in the attached Figure 1 As shown, the front and rear stoppers 7 and 8 are provided in front and rear of the lifting assembly 5, respectively. The rear stopper can be used to locate the position of the pallet. When the pallet moves to the position of the rear stopper, the magnetic ring on it just faces the clamping claw. The front stopper is used to stop the pallet on the pallet line. The front and rear stoppers are both pneumatic stoppers. This design allows the pallet line to run without stopping, and the oil injection of the magnetic ring is completed during the operation of the pallet line.

[0049] During specific work, the pallet line is always in operation. When the pallet passes the front blocker and moves to the rear blocker, it stops under the action of the rear blocker. At this time, the front blocker blocks the pallet on the pallet line, and then the lifting assembly is activated to lift the pallet to make it separate from the pallet line. Then the magnetic ring is clamped by the linear slide and the clamping jaw assembly and transferred to the oil receiving nozzle. Then the linear cylinder is activated to make the nozzle enter the inner hole of the magnetic ring. At this time, the sprayer works to spray oil into the inner hole of the magnetic ring. After the oil spraying is completed, the linear cylinder is reset, the clamping jaw assembly clamps the magnetic ring and transfers it to the pallet and then resets it. Then the lifting assembly is reset, the rear blocker is retracted, and the magnetic ring after the oil spraying leaves the clamping station under the transmission of the pallet line, the rear blocker is extended, and the front blocker is retracted, so that the next pallet enters the clamping station, and the above steps are repeated.

[0050] Embodiment 5

[0051] Based on the fourth embodiment, as shown in the attached Figure 1 As shown, the side of the pallet line 10 away from the injection station 4 is further provided with a first proximity switch 9a, a second proximity switch 9b and a third proximity switch 9c, wherein: the first proximity switch 9a is arranged in front of the front blocker 7, and is used to detect whether there is any incoming material on the pallet line 10; the second proximity switch 9b is arranged in the area where the lifting plate 5.1 is located, and is used to detect whether there is a pallet at the position of the lifting assembly 5; the third proximity switch 9c is arranged behind the rear blocker 8, and is used to detect whether the pallet on the lifting assembly 5 has left.

[0052] In specific implementation, when the second proximity switch detects a pallet, the front blocker extends to block the pallet on the pallet line; when the photoelectric switch detects two signals within a certain period of time, it indicates that the oil injection work is completed, and after the lifting assembly is reset, the rear blocker retracts; when the second proximity switch does not detect a pallet, and the third proximity switch detects a pallet, it indicates that the round of oil injection work is completed, the rear blocker extends, and the front blocker retracts. In this way, automatic oil injection is achieved.

[0053] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
