The positioning plate 52 is located at the output end of the lifting cylinder 4 and is fixedly connected to the output end of the lifting cylinder 4. The bottom ends of the positioning plate 52 are connected to the carrier plate 32 through linear bearings 33. Positioning pins 54 are fixedly installed at two symmetrically distributed corners on the positioning plate 52. Spring marbles 53 are symmetrically distributed at the four inner corners of the positioning plate 52. Z-direction positioning plates 51 are symmetrically distributed at the front and rear ends of the positioning plate 52, and the Z-direction positioning plates 51 are fixedly connected to the carrier plate 32.

[0020] In this embodiment: spring balls 53 are symmetrically distributed at the four inner corners of the positioning plate 52, and Z-direction positioning plates 51 are symmetrically distributed at the front and rear ends of the positioning plate 52. The Z-direction positioning plate 51 is fixedly connected to the carrier plate 32. The spring balls 53 can compensate for the processing and assembly errors of the Z-direction positioning, thereby improving the operation accuracy.

[0021] Specifically, a sensor positioning groove 7 is provided on the rear side of the jacking base plate 3, and a limit sensor 8 is fixedly engaged with the inner top end of the sensor positioning groove 7. The limit sensor 8 is slidably connected to the sensor positioning groove 7, and the limit sensor 8 is electrically connected to an external power supply; when the servo module 22 drives the jacking mechanism to move left and right, the limit sensor 8 performs limit sensing on the moving position of the jacking mechanism, so that the horizontal movement position of the carrier driven by the jacking mechanism is more accurate.

The Z-direction positioning plate 51 performs secondary limit on the carrier as a Z-direction reference, and the servo motor 2 drives the servo module 22 to move horizontally through the coupling 21, and the servo module 22 drives the entire jacking mechanism to move left and right to achieve the purpose of translating the carrier. When the servo module 22 drives the jacking mechanism to move left and right, the limit sensor 8 performs limit sensing on the moving position of the jacking mechanism, so that the horizontal moving position of the carrier driven by the jacking mechanism is more accurate, and combined with the spring marbles 53 installed on the positioning plate 52, the carrier is lifted and floated on the positioning plate 52, thereby compensating for the processing error and assembly error of the workpiece and ensuring the Z-direction positioning accuracy.
