[0042] As Figure 1 shown, it is the automatic magnetic abrasive polishing and cleaning production line 100 shown in the present utility model, which is used for polishing and cleaning workpieces.

[0043] As Figure 1 shown, the automatic magnetic abrasive polishing and cleaning production line 100 includes: a handling unit 10, a grinding barrel 20, and a feeding unit 30, a grinding and cleaning unit 40, and a discharging unit 50 arranged in sequence according to the processing order.

In this application, the handling unit 10 is adopted to place the workpieces provided by the feeding unit 30 into the grinding barrel 20 and drive the grinding barrel 20 to be transported from the grinding and cleaning unit 40 to the discharging unit 50. After the positioning mechanism 51 of the discharging unit 50 clamps the grinding barrel 20, the workpieces in the grinding barrel 20 are clamped and recycled by the recycling mechanism 52. This method is conducive to automatically magnetically abrasive polishing and cleaning workpieces, reducing the processes and time of manually separating debris and abrasive needles, so as to achieve the purpose of improving the efficiency during magnetic abrasive polishing and cleaning work.

[0044] Hereinafter, in combination with Figures 1 to 5 , the above-mentioned automatic magnetic abrasive polishing and cleaning production line 100 will be further described.

[0045] As Figures 1 to 2As shown in the figure, the handling unit 10 includes a support frame 11, a displacement driving mechanism 12 installed on the support frame 11, and a clamping mechanism 13 connected to the displacement driving mechanism 12. The support frame 11 encloses a handling area 111 for accommodating the loading unit 30, the grinding and cleaning unit 40, and the unloading unit 50. The displacement driving mechanism 12 is used to drive the clamping mechanism 13 to move within the handling area 111, and the clamping mechanism 13 is used to clamp the workpiece or the grinding barrel 20.

[0046] Specifically, as Figure 2 shown in the figure, the displacement driving mechanism 12 includes a lateral driving member 121 installed on the support frame 11, a longitudinal driving member 122 connected to the lateral driving member 121, and a vertical driving member 123 connected to the longitudinal driving member 122.

[0047] As Figure 3 shown in the figure, the clamping mechanism 13 includes a clamping driving member 131 and clamping jaws 132 connected to the clamping driving member 131. Among them, the number of clamping jaws 132 is two. The clamping driving member 131 can be selected as a parallel opening and closing type air gripper and is used to control the two clamping jaws 132 to approach or separate from each other to grasp the workpiece or the grinding barrel 20. The length of the clamping jaws 132 is longer than the depth of the barrel of the grinding barrel 20 to facilitate the clamping jaws 132 to extend into the grinding barrel 20 to grasp the workpiece.

[0048] As Figure 3 shown in the figure, the grinding barrel 20 includes a bottom plate 21, a surrounding wall 22, a cantilever 23, a partition plate 26, and a side arm 27. The bottom plate 21 and the surrounding wall 22 form a receiving space 24 for accommodating the workpiece and are provided with a separation hole 25 communicating with the receiving space 24. The separation hole 25 is used for the grinding needles and debris to pass through to separate the grinding needles and debris from the workpiece. The cantilever 23 is connected to the bottom plate 21 and is used for the handling unit 10 to grasp. The partition plate 26 is arranged in the receiving space 24 and is used to separate the receiving space 24 to facilitate placing more workpieces, thereby improving the grinding and cleaning efficiency. The side arm 27 is connected to the surrounding wall 22 and is used for the positioning mechanism 51 to clamp.

Among them, the feeding mechanism 31 is used to convey the workpiece, and the collecting hopper 32 is used to store and continuously supply the workpiece to the feeding mechanism 31.

[0050] Specifically, as Figure 4As shown in the figure, the feeding mechanism 31 includes a conveyor 311, side plates 312 connecting the conveyor 311, and a baffle 313 installed on the conveyor 311. Among them, the conveyor 311 is a belt feeder. The conveyor 311, side plates 312, and baffle 313 together enclose a feeding channel 314. The width of the feeding channel 314 is greater than the diameter of one tool and less than the diameter of two tools, so as to provide one workpiece for the handling unit 10 at a time.

[0051] As Figure 4 shown in the figure, the aggregate hopper 32 is provided with a discharging space 321 and an aggregate port 322 communicating with the discharging space 321. The discharging space 321 gradually contracts in the direction towards the aggregate port 322, and the aggregate port 322 communicates with the feeding channel 314 of the feeding mechanism 31.

[0052] As Figure 1 shown in the figure, the grinding and cleaning unit 40 includes a grinding mechanism 41, a screening mechanism 42, and a cleaning mechanism 43 arranged in sequence according to the processing order. Among them, the grinding mechanism 41 is a magnetic grinding machine. The screening mechanism 42 includes a vibrating screening machine 421 and a recovery bucket 422 for receiving the grinding needles and debris screened by the vibrating screening machine 421. The cleaning mechanism 43 has a cleaning tank 431 and a drying tank 432. The cleaning tank 431 is used for cleaning workpieces, and the drying tank 432 is used for drying the cleaned workpieces.

[0053] As Figure 1 shown in the figure, the discharging unit 50 includes a positioning mechanism 51 and a recovery mechanism 52. Among them, the positioning mechanism 51 is used for clamping the grinding barrel 20, and the recovery mechanism 52 receives workpieces.

[0054] Specifically, as Figure 5 shown in the figure, the positioning mechanism 51 includes a frame 511, a lifting drive 512, a placement seat 513, a limit frame 514, a barrel clamping drive 515, clamping pieces 516, a horizontal pushing drive 517, and a side pushing drive 518. Among them, the lifting drive 512, barrel clamping drive 515, side pushing drive 518, and horizontal pushing drive 517 are all cylinders. The lifting drive 512 is installed on the frame 511 and is used to drive the placement seat 513 to lift. The placement seat 513 is used to install the limit frame 514 and the side pushing drive 518. The barrel clamping drive 515 is connected to the clamping pieces 516 and is used to control the clamping pieces 516 to clamp the side arm 27 of the grinding barrel 20. The horizontal pushing drive 517 is used to control the barrel clamping drive 515 to approach or move away from the limit frame 514, so as to jointly position the grinding barrel 20 through the cooperation of the clamping pieces 516 connected to the barrel clamping drive 515 and the limit frame 514. The number of side pushing drives 518 is two, and the two side pushing drives 518, together with the limit frame 514 and the barrel clamping drive 515, enclose a positioning space 519 for placing the grinding barrel 20.

[0055] As Figure 1As shown, the recycling mechanism 52 includes a material conveyor 521, a blanking manipulator 522, and an inspection platform 523 arranged in sequence according to the processing order. Among them, the material conveyor 521 is a belt feeder for receiving workpieces and transporting them to the blanking manipulator 522. The blanking manipulator 522 is used to grab the workpieces and transport them to the inspection platform 523 for monitoring the workpieces.

[0056] The working principle of the automatic magnetic abrasive cleaning production line 100 provided by this application is as follows: As Figure 1 shown, the workpiece to be processed is placed in the aggregate hopper 32 of the loading unit 30. The aggregate hopper 32 continuously supplies workpieces to the feeding mechanism 31. The displacement driving mechanism 12 of the handling unit 10 drives the clamping mechanism 13 to grab the workpiece and place it in the receiving space 24 of the grinding barrel 20. Then, the cantilever 23 of the clamping grinding barrel 20 is controlled, and the grinding barrel 20 is sequentially passed through the grinding mechanism 41, screening mechanism 42, and cleaning mechanism 43 of the cleaning unit 40. After the workpieces in the grinding barrel 20 are ground and cleaned, the grinding barrel 20 is grabbed and placed at the positioning mechanism 51 of the blanking unit 50. Through the cooperation of the limit frame 514, barrel clamping driving part 515, horizontal pushing driving part 517, and side pushing driving part 518 of the positioning mechanism 51, the grinding barrel 20 is fixedly clamped. Finally, the handling unit 10 takes out the ground and cleaned workpieces in the grinding barrel 20 and places them at the material conveyor 521 of the recycling mechanism 52 for the material conveyor 521 to transport to the blanking manipulator 522. The blanking manipulator 522 grabs the workpiece and sends it to the inspection platform 523 for inspection to realize the automatic magnetic abrasive cleaning of the workpiece.

[0057] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0058] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
