Embodiment
[0014] Embodiment: A scissor lift exchange workbench, including a frame 4, a workbench 7, a support body 102, a vertical drive mechanism and a horizontal drive mechanism, the support body 102 is provided with a guide rail 101, and the horizontal drive mechanism can The worktable 7 is driven to make a reciprocating linear motion along the guide rail 101 on the support body 102. The vertical drive mechanism includes first and second links 201, 202 that are cross-hinged, a linear drive device and a vertical guide block 5. The support body 102 There is a first elongated hole 206 along the direction of the guide rail 101, the frame 4 is provided with a second elongated hole 205 parallel to the first elongated hole 206, the upper end of the first connecting rod 201 and the side wall of the support body 102 Hinged, the lower end of the first link 201 is pivotally connected to the second elongated hole 205 on the frame 4, the upper end of the second link 202 is pivoted to the first elon...

The invention discloses a scissor lift pallet changer. A horizontal driving mechanism can drive a worktable to move along guide rails on support bodies; a first strip hole is formed in each support body in the direction of the guide rail; a second strip hole parallel to the first strip hole is formed in a machine frame; the upper end of each first connecting rod is hinged to the side wall of each support body, and the lower end of each first connecting rod is pivoted to the interior of the second strip hole in the machine frame; the upper end of each second connecting rod is pivoted to the interior of the first strip hole in the support body, and the lower end of each second connecting rod is hinged to the side wall of the machine frame; a linear driving device drives the lower ends of the first connecting rods to reciprocate in the length direction of the second strip holes; vertical guide blocks are fixedly arranged on the machine frames; vertical guide grooves are formed in the support bodies; and the guide blocks can be inserted into the guide grooves in a sliding manner in the vertical direction. The scissor lift pallet changer realizes translation-free synchronous lifting of a worktable and a lift frame and enables the worktable to be positioned more accurately in the horizontal direction, and as the support bodies and support rollers are in rolling support, the friction force is small, the movement is smooth and the probability of abrasion is low.
Description
Technical field [0001] The invention relates to an exchange table for a laser cutting machine, in particular to a scissor type lifting exchange table. Background technique [0002] In order to give full play to the efficiency of the laser, the laser cutting machine is usually equipped with an exchange table to realize the cutting process and the loading and unloading process at the same time. Lifting and lowering of the workbench is an important link to realize the exchange of the workbench. The existing lifting device usually uses a small gear to mesh with a large gear, and a shaft extends from the center of the large gear (a crank is formed between the center of the large gear and the shaft, and the center distance is the length of the crank) to lift the worktable The frame is hinged. When the pinion gear rotates, the crank can be driven to move between the top dead center and the bottom dead center, and the workbench lifting frame can be raised and lowered. Obviously, during...
