[0046] like Figure 1-5 , a lifting frame, comprising: a lateral drive unit 1, a lifting drive unit 2, a linear drive 3 and a frame body 4;

[0047] The transverse driving unit 1 comprises: a driving gear 11, a driven gear 12, an X-direction synchronization shaft 13, a Y-direction synchronization shaft 14 and a transverse rack 15;

[0048] The driving gear 11 and the driven gear 12 are respectively arranged on the X-direction synchronization shaft 13, and the three are connected in synchronous rotation; the transverse racks 15 of the two adjacent transverse drive units 1 are connected in synchronous movement through the Y-direction synchronization shaft 14; the transverse rack 15 is meshed with the driving gear 11; the output end of the linear drive 3 is connected to the transverse rack 15 or the Y-direction synchronization shaft 14 of one of the transverse drive units 1, and is used to drive the transverse rack 15 or the Y-direction synchronization shaft 14 to move horizontally, drive the other transverse racks 15 to move horizontally, and the driven gear 12 of the transverse drive unit 1 rotates;

[0049] The lifting drive unit 2 includes: a vertical rack 21;

[0050] The vertical racks 21 of the multiple lifting drive units 2 are respectively connected to the frame body 4; the vertical racks 21 are vertically arranged corresponding to the driven gear 12, and the vertical racks 21 are meshed with the vertical racks 21; the rotation of the driven gear 12 is used to drive the vertical racks 21 to move up and down, and drive the frame body 4 to move up and down.

[0051] The present solution provides a lifting drive mechanism, which uses a linear drive 3 as a single driving source to drive the transverse rack 15 to move, thereby driving the Y-axis synchronization axis 14 to move, and then the transverse racks 15 of multiple transverse drive units 1 to move synchronously, and finally drive the driven gear 12 to rotate, so that the vertical rack 21 can be lifted and moved, and the frame body 4 can be driven to rise and fall synchronously at different positions of the frame body 4. The lifting of the frame body 4 is stable, which solves the problem of uneven force on the existing frame body 4 during lifting and lowering, resulting in deviation in the placement or transfer position of the workpiece.

[0052] Specifically, the present solution has a plurality of transverse drive units 1, which can be arranged at different positions of the frame body 4 as needed, and the driven gear 12 of each transverse drive unit 1 can be set to a plurality, which can also be arranged at different positions of the frame body 4; the number of lifting drive units 2 is multiple, and can also be correspondingly arranged on the driven gear 12; and the advantage of the present solution is that multiple lifting drive units 2 can be driven to rise and fall synchronously by a single driving source; specifically, the output end of the linear drive 3 is connected to the transverse rack 15 or the Y-direction synchronization shaft 14 of one of the transverse drive units 1, and can drive the transverse rack 15 or the Y-direction synchronization shaft 14 to move horizontally, and the Y-direction synchronization shaft 14 connects the transverse racks 15 of two adjacent transverse drive units 1 into one; therefore, after the transverse rack 15 or the Y-direction synchronization shaft 14 connected to the linear drive 3 moves, on the one hand, it can drive the transverse rack 15 to move, so as to drive the driving gear 11 to rotate under the meshing action, so as to drive the X-direction synchronization shaft 13 to rotate, thereby driving multiple driven gears on the X-direction synchronization shaft 13 The gears 12 rotate synchronously, and when the driven gear 12 rotates, the vertical rack 21 is driven to rise and fall through the meshing structure, so that the driven gears 12 at different positions simultaneously drive different vertical racks 21 to rise and fall; on the other hand, after the transverse rack 15 or the Y-direction synchronous shaft 14 moves, the transverse racks 15 of other transverse drive units 1 can be driven to move through the Y-direction synchronous shaft 14, so that the driving gears 11 of other transverse drive units 1 rotate, so as to drive multiple driven gears 12 to rotate through the X-direction synchronous shaft 13, and the driven gear 12 drives the vertical rack 21 to rise and fall through the meshing structure, so that the vertical rack 21 of the corresponding lifting drive unit 2 of the driven gear 12 is synchronously lifted and lowered; in this way, the linear drive 3 can directly and indirectly drive the transverse racks 15 of different transverse drive units 1 to move, thereby driving multiple vertical racks 21 to rise and fall, so that multiple positions of the frame body 4 are driven to rise and fall synchronously, and the frame body 4 maintains uniform force during lifting, which can ensure that the workpiece on the frame body 4 remains stable during the lifting process and prevent position deviation problems.

[0053] The linear drive 3 is a well-known mechanism with a driving and moving function, such as an air cylinder, an oil cylinder, a manipulator, or a combination of a motor and a screw, etc., as long as it can drive the transverse rack 15 to move.

[0054] Optimally, the linear drives 3 are arranged in pairs;

[0055] Between the two lateral drive units 1, one end of the lateral racks 15 of the two are respectively connected to the output end of one of the linear drives 3, and the other ends of the two are respectively connected to the Y-direction synchronization shaft 14;

[0056] The output end of the linear drive 3 is retractable and retractable in a resettable manner; one output end of the linear drive 3 is extended, and the output end of the other linear drive 3 is retracted, and the output ends of the two linear drives 3 move in the same direction.

[0057] The present scheme preferably arranges the linear drives 3 in pairs and respectively locates them in the two transverse drive units 1; the transverse drive units 1 may be in adjacent positions or in separated positions; the output ends of the two linear drives 3 are connected to the transverse racks 15 of the two transverse drive units 1, and the transverse racks 15 of the transverse drive units 1 are directly or indirectly connected to the Y-direction synchronization axis 14, so that when the output end of the linear drive 3 on one side is extended, the transverse rack 15 connected to the output end of the linear drive 3 can be driven to move in the telescopic direction, and when the output end of the linear drive 3 on the other side is extended, the transverse rack 15 connected to the output end of the linear drive 3 can be driven to move in the telescopic direction; and the present scheme arranges a pair of linear drives 3, the output end of one of the linear drives 3 can be extended, and the output end of the other linear drive 3 can be retracted, so as to jointly drive the Y-direction synchronization axis 14 and the transverse rack 15 to move in one direction, thereby improving the driving force of the linear drive 3, making the lifting and lowering of the frame body 4 more stable, and the frame body 4 can place more workpieces.

[0061] One end of the rotating arm 16 is rotatably connected to the transverse rack 15 , and the other end of the transverse rack 15 is rotatably connected to the output end of the linear drive 3 .

[0062] When the linear drive 3 is a cylinder, the output end of the linear drive 3 is connected to the transverse rack 15 through the rotating arm 16 so as to be rotatable and adjustable; when the linear drive 3 drives the transverse rack 15 to move, since the rotating arm 16 is rotatable, the linear drive 3 drives the rotating arm 16 to rotate a certain angle and then indirectly drives the transverse rack 15 to move, so that the rotating arm 16 can provide a buffering effect when the cylinder is linearly driven by adjusting the rotation of the rotating arm 16, so as to avoid the cylinder directly impacting or connecting the transverse rack 15, thereby improving the service life and movement stability of the transverse rack 15. At the same time, the output end of the linear drive 3 extends, and the output end of the other linear drive 3 contracts, and the output ends of the front and rear linear drives 3 move in the same direction, so that the two linear drives 3 apply force in the same direction when extending or contracting, thereby greatly improving the driving efficiency.

[0063] Optimally, the lifting drive unit 22 further includes: a lifting support seat 22, a lifting guide rail 23 and a lifting slide block 24;
