A pressing frame connecting plate 10 is arranged at the front end of the bottom of the lower sliding table connecting plate 3. A pressing frame assembly 11 is fixedly connected to the front end of the pressing frame connecting plate 10.

[0022] Specifically, the transverse synchronous belt assembly 4 specifically includes a synchronous belt arranged horizontally in the transverse direction and an active synchronous wheel and a driven synchronous wheel meshed with the synchronous belt; the longitudinal synchronous belt assembly 7 specifically includes a synchronous belt arranged horizontally in the longitudinal direction and an active synchronous wheel and a driven synchronous wheel meshed with the synchronous belt.

[0023] In this embodiment, the specific sliding structure of the upper slide connecting plate 2 is: a pair of transverse slide rails 12 are arranged at the bottom of the crossbeam 1, and the upper slide connecting plate 2 is slidably arranged on the transverse slide rails 12 through a plurality of transverse sliders 13; a groove corresponding to the transverse synchronous belt assembly 4 is arranged above the upper slide connecting plate 2, and an upper synchronous belt pressure plate 14 is fixed in the groove, and the lower layer synchronous belt of the transverse synchronous belt assembly 4 is pressed between the upper slide connecting plate 2 and the upper synchronous belt pressure plate 14.

[0024] In this embodiment, the specific sliding structure of the lower slide connecting plate 3 is: a pair of longitudinal slide rails 15 are arranged at the bottom of the upper slide connecting plate 2, and the lower slide connecting plate 3 is slidably arranged on the longitudinal slide rails 15 through a plurality of longitudinal sliders 16; a lower synchronous belt pressure plate 17 is fixed above the lower slide connecting plate 3, and the lower synchronous belt of the longitudinal synchronous belt assembly 7 is pressed between the lower slide connecting plate 3 and the lower synchronous belt pressure plate 17.

[0025] In this embodiment, the lateral motor transmission mechanism 5 is a lateral deceleration synchronous belt, and the lateral displacement motor 6 is connected to the lateral synchronous belt assembly 4 through the lateral deceleration synchronous belt assembly. The lateral displacement motor 6 is arranged below the lateral synchronous belt assembly 4. The driven synchronous wheel of the lateral deceleration synchronous belt assembly and the active synchronous wheel of the lateral synchronous belt assembly 4 are mounted on the same lateral synchronous wheel shaft 18. Specifically, the lateral deceleration synchronous belt includes a vertically arranged synchronous belt and an active synchronous wheel and a driven synchronous wheel meshed therewith. The active synchronous wheel is mounted on the motor shaft of the lateral displacement motor 6, and its deceleration function is realized by the different numbers of teeth of the active synchronous wheel and the driven synchronous wheel. The lateral displacement motor 6 is fixedly mounted on the frame, and a certain distance can be left between the horizontal beam 1 by arranging it up and down, so as to facilitate its installation and maintenance.

[0026] In this embodiment, the longitudinal motor drive mechanism 8 is a longitudinal reduction synchronous belt.

The lateral drag chain 21 and the longitudinal drag chain 23 are used to install their corresponding cable lines, air pressure pipes, oil pressure pipes and other components.

[0030] On the one hand, proximity sensors are respectively arranged on both sides of the above-mentioned upper slide table connecting plate 2. The lateral position of the upper slide table connecting plate 2 can be monitored through the proximity sensors to prevent collisions.
