Referring to fig. 1 to 4, the present invention provides a deburring mechanism 100, which includes a robot 10, a grinding wheel 12 fixed on the robot 10, and a product rotating device 20. The product rotation device 20 is used to position and rotate at least one product 14 such that a different surface of the at least one product 14 is opposite the grinding wheel 12. The robot 10 is configured to move the grinding wheel 12 such that the grinding wheel 12 contacts the product 14 to remove burrs from different surfaces of the at least one product 14.

The product rotating device 20 includes a base 22, a transmission member 40 and a driving member 70. The transmission member 40 is connected to the base 22 and the driving member 70, and is configured to be connected to the at least one product 14, and drive the at least one product 14 to rotate under the driving of the driving member 70.

The base 22 includes two positioning plates 24 disposed at intervals and at least one fixing rod 26 fixedly connected between the two positioning plates 24. Specifically, the base 22 includes three fixing rods 26 connected between the two positioning plates 24. The base 22 further includes two fixing blocks 28, and the two fixing blocks 28 are fixed on two opposite sides of the two positioning plates 24. Each of the fixing blocks 28 is formed with a receiving groove 30 extending from one end of the fixing block 28 to the other end of the fixing block 28.

The transmission member 40 includes at least one pair of positioning members 42, at least one pair of linkage rods 44, a connecting rod 46, a positioning pin 48 and a moving block 50. The at least one pair of positioning members 42 are rotatably fixed on the two positioning plates 24 and are disposed opposite to each other. Each pair of positioning members 42 is connected to both ends of one of the products 14 to position one of the products 14. In one embodiment, the product rotation device 20 includes a plurality of positioning members 42. A plurality of through holes 32 are formed in each positioning plate 24. Each of the positioning members 42 includes a fixed shaft 52. The two fixed shafts 52 of each two positioning members 42 are relatively and rotatably fixed in the two through holes 32 of the two positioning plates 24. One end of each of the fixed shafts 52 near the other fixed shaft 52 extends out of a positioning shaft 54 parallel to the positioning plate 24. The product 14 is formed with registration holes 56 at both ends. Every two of the positioning shafts 54 are disposed in two of the positioning holes 56 of a product 14 in a transition fit manner.

Each linkage rod 44 is fixedly connected with one positioning piece 42. The connecting rod 46 is fixedly connected with the at least one pair of linkage rods 44. The connecting rod 46 and the positioning member 42 are fixed at two ends of the linkage rod 44. The moving block 50 is formed with an inclined slide groove 58. The positioning pin 48 is fixed on the connecting rod 46 and is arranged in the sliding groove 58. The detent pin 48 can slide back and forth along the detent slot 58. The driving member 70 is slidably disposed in the receiving groove 30. One end of the driving element 70 is fixedly connected to the moving block 50, and is configured to drive the moving block 50 to move back and forth in a direction parallel to the connecting rod 46, so that the positioning pin 48 moves back and forth along the sliding groove 58 under the pushing of the moving block 50, and the connecting rod 46 is driven to drive the linkage rod 44, the positioning element 42, and the product 14 to rotate back and forth. In one embodiment, the driver 70 is a linear air cylinder.

In one embodiment, the chute 58 includes two ends, an upper end 57 and a lower end 59. When the positioning pin 48 slides to the lower end point 59, the linkage rod 44 is perpendicular to the connecting rod 46, and the upper surface of the product 14 is in a horizontal position and opposite to the grinding wheel 12. When the positioning pin 48 slides from the lower end point 59 to the upper end point 57, the link rod 46 drives the linkage rod 44 and the positioning element 42 to rotate, so that one end of the positioning shaft 54 on the positioning element 42 rotates upward from a horizontal position. When the positioning pin 48 slides to the upper end point 57, the linkage rod 44 is parallel to the connecting rod 46, and the product 14 rotates 90 degrees from the initial position, so that the side surface of the product 14 adjacent to the upper surface is opposite to the grinding wheel 12. In this way, the grinding wheel 12 may perform a deburring process on the upper surface and the side surface of the product 14. It will be appreciated that the angle of inclination and length of the chute 58 is determined by the desired angle of rotation of the product 14, and can be set according to the desired angle of rotation of the product 14.

The base 22 also includes at least a pair of stop blocks 34. The at least one pair of stoppers 34 are fixed to the two positioning plates 24. Each stopper 34 is located at one side of one positioning member 42, and a gap between each stopper 34 and an adjacent positioning shaft 54 is smaller than the width of the product 14, so as to prevent the product 14 from being separated from the positioning shaft 54 when the product 14 rotates to a horizontal position.

The product rotation device 20 further comprises at least one protection cover 60, and the at least one protection cover 60 covers the base 22, the at least one positioning element 42 and the driving element 70. The positioning member 42 and the driving member 70 are hidden between the protection cover 60 and the positioning plate 24.

The driving member 40 of the deburring mechanism 100 and the product rotating device 20 moves under the driving of the driving member 70 and drives the product 14 to rotate, so that different surfaces of the product 14 are opposite to the grinding wheel 12, and thus burrs on different surfaces of the product 14 are removed through the grinding wheel 12, the product 14 does not need to be manually rotated, and the efficiency of removing the burrs on the product 14 is improved.

It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that suitable changes and modifications to the above embodiments are within the scope of the present disclosure as long as they are within the spirit of the present invention.
