[0006] According to the magnetic grating encoder and supporting structure, a first anti-slip block is fixedly connected to the guide rail support, and the first anti-slip blocks are multiple and distributed in a rectangular array to prevent the roller from detaching from the guide rail support.

[0007] According to the magnetic grating encoder and supporting structure, a second anti-slip block is fixedly connected to the guide rail, and the number of the second anti-slip blocks is two and they are distributed on the left and right to prevent the roller from detaching from the guide rail.

The outer surfaces of the rollers 9 are respectively slidably connected to the guide rail supports 5 and the guide rail 7. A first anti-slip block 14 is fixedly connected to the guide rail support 5. The first anti-slip block 14 is fixedly connected to the guide rail support 5. There are multiple anti-slip blocks 14 distributed in a rectangular array, a second anti-slip block 15 is fixedly connected to the guide rail 7, there are two second anti-slip blocks 15 and they are distributed on the left and right, two third docking holes 13 are provided on the nut 3, a first slide groove 11 is provided on the guide rail support 5, the outer surface of the roller 9 is slidably connected to the first slide groove 11, a second slide groove 16 is provided on the guide rail 7, the outer surface of the roller 9 is slidably connected to the second slide groove 16, a plurality of limit blocks are arranged on the roller connecting frame 2, the side surface of the roller 9 is in contact with the limit block, a first docking hole 10 is provided on the docking block 4, and a second docking hole 12 is provided on the guide rail support 5.

[0024] Working principle: Through the first docking hole 10 reserved on the docking block 4 and the second docking hole 12 reserved on the guide rail support 5, bolts and other fasteners can be used to connect the support frame 1, the docking block 4, the guide rail support 5, the magnetic grid receiver 6 and other devices, and at the same time, the support frame 1, the docking block 4, the magnetic grid receiver 6 and the guide rail support 5 are fixed, and through the third docking hole 13 reserved on the nut 3, bolts and other fasteners can be used to connect the nut 3, the guide rail 7, the magnetic grid bar 8 and the telescopic cylinder or other power devices capable of reciprocating movement. When the connection is completed, the telescopic cylinder is started, so that the nut 3, the guide rail 7 and the magnetic grid bar 8 can be reciprocated. At the same time, the rollers 9 on the two roller connecting frames 2 are respectively in the first slide groove 11 and the second slide groove 16 to form a cross roller guide pair, which prevents the nut 3, the guide rail 7 and the magnetic grid bar 8 from deviating during the movement, so that the nut 3, the guide rail 7 and the magnetic grid bar 8 can only reciprocate in a straight line.

Fasteners such as bolts are used to connect the support frame 1, the docking block 4, the guide rail support 5, the magnetic grating receiver 6 and other devices.
