[0007] Preferably, there are two rotating shafts, and the two rotating shafts are symmetrically arranged with reference to the central axis of the processing platform as the axis of symmetry.
[0008] Preferably, the lower end of the clamping plate is in contact with and slidably connected to the outer wall of the conveying roller wheel that is rotatably connected inside the groove, thus ensuring a better clamping and deviation-correcting effect of the clamping plate.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0021] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.
[0022] The present utility model provides a burr grinding device for a die-casting cylinder head as shown in Figures 1-4 which includes a processing pedestal 1. A channel 2 is provided at the top of the processing pedestal 1, and a conveyor roller 3 is rotatably connected to the inner wall of the channel 2, and a cylinder head is placed on the conveyor roller 3 to facilitate the conveyance of the cylinder head. A cavity 4 is provided inside the processing pedestal 1, and a rotating shaft 5 is rotatably connected to the inside of the cavity 4 through a bearing, and a clamping plate 6 is fixedly connected to the outer wall of the upper end of the rotating shaft 5, so that the two clamping plates 6 perform the work of correcting the deviation of the cylinder head on the conveyor roller 3 and limiting during the burr grinding process, ensuring the accuracy of processing. A gear 7 is fixedly sleeved on the outer wall of the rotating shaft 5, and the gear 7 is meshed with a rack 8. A limit block 9 is fixedly connected to the side wall of the rack 8, and the limit block 9 moves inside a limit groove 10, and the limit groove 10 communicates with the cavity 4. A screw 11 is rotatably connected to one end of the rack 8, and the screw 11 is in threaded connection with a threaded groove 15 preset inside the processing pedestal 1, and a turntable 14 is fixedly connected to the end of the screw 11. A robot arm 16 is fixedly connected to the side wall of the processing pedestal 1, and a grinding rod 17 is installed at the end of the robot arm 16 to facilitate the grinding of the burrs on the edge of the cylinder head.
[0023] There are two rotating shafts 5 in number, and the two rotating shafts 5 are symmetrically arranged with reference to the central axis of the processing pedestal 1 as the axis of symmetry.
[0024] The lower end of the clamping plate 6 is in contact with and slidably connected to the outer wall of the conveyor roller 3 rotatably connected inside the channel 2, so as to ensure better clamping and deviation correction effect of the clamping plate 6.
[0025] The rack 8 is in a "Z" shape, and tooth blocks are provided on the outer walls of two parallel body blocks of the rack 8. The two tooth blocks are respectively meshed and connected with the gears 7 fixedly sleeved on the outer circles of the two rotating shafts 5. During the movement of the "Z"-shaped rack 8, the two groups of parallel tooth blocks are respectively meshed and connected with the two gears 7, so that the two gears 7 rotate in different directions.
[0026] There are two limiting blocks 9 in number, and the two limiting blocks 9 are respectively fixedly connected to the outer walls of two corners of the rack 8. The outer wall of the limiting block 9 is in contact with the inner wall of the limiting groove 10 and realizes a sliding connection, ensuring the stability of the movement of the rack 8.
[0027] A disc 12 is fixedly connected to the top inside the cavity 4 of the screw rod 11. The outer diameter of the outer circle of the disc 12 is larger than the outer diameter of the outer circle of the screw rod 11. The outer circle of the disc 12 and the smooth rod part at the front end of the screw rod 11 are rotationally connected to the rotation groove 13. In this way, when the screw rod 11 rotates, it will not have any influence on the rack 8. At the same time, when the end of the screw rod 11 moves, it can also drive the rack 8 to move.
[0028] Working principle: When using a die-casting cylinder head burr grinding device, first, by twisting the turntable 14, the screw rod 11 fixedly connected to the turntable 14 rotates. During the rotation of the screw rod 11 threadedly connected to the processing pedestal 1, the end of the screw rod 11 moves, and then drives the position of the rack 8 rotationally connected to the screw rod 11 to move linearly. The limiting blocks 9 fixedly connected to both sides of the rack 8 move inside the limiting groove 10, ensuring the stability of the movement of the rack 8. During the movement of the "Z"-shaped rack 8, the two groups of parallel tooth blocks are respectively meshed and connected with the two gears 7, so that the two gears 7 rotate in different directions. At this time, the rotating shafts 5 inserted into the inner circles of the two gears 7 rotate in different directions and then drive the two clamping plates 6 to move. The clamping ends of the two clamping plates 6 move towards each other or away from each other, so that the gap between the clamping ends of the two clamping plates 6 is adjusted, enabling the two clamping plates 6 to perform the work of rectifying different-sized cylinder heads on the conveying roller 3 and limiting during burr grinding, ensuring the accuracy of processing. The robotic arm 16 drives the grinding rod 17 to perform burr grinding.
