[0027] The following will describe in detail the preferred embodiments of the present invention with reference to the accompanying drawings and further elaborate on the present invention.

[0028] First, it will be described in combination with Figures 1 - 5 A horizontal push type variable stroke lifting mechanism according to an embodiment of the present invention is used to realize the lifting of an object and has a wide range of application scenarios.

[0029] Such asFigures 1 - 5 As shown in the figure, a jacking mechanism with a horizontally pushable variable stroke according to an embodiment of the present utility model includes a support platform 1, a pair of guide rails 2, a support frame 3, four support blocks 4, a driving unit, a jacking frame 7, four rollers 8, four guide rods 6, and four linear bearings 91.

[0030] Specifically, as Figures 1 - 5 shown in the figure, a pair of guide rails 2 are arranged on the support platform 1 and are used for guiding the movement of the four support blocks 4.

[0031] Specifically, as Figures 1 - 5 shown in the figure, the support frame 3 is arranged on the top of the support platform 1.

[0032] Specifically, as Figures 1 - 5 shown in the figure, the four support blocks 4 are respectively arranged on the two outer side walls of the support frame 3 and are slidably connected to a pair of guide rails 2. On the top of each of the four support blocks 4, three first support surfaces, second support surfaces, and third support surfaces are sequentially arranged from high to low. The first support surface and the second support surface, and the second support surface and the third support surface are connected by inclined surfaces.

[0033] Specifically, as Figures 1 - 5 shown in the figure, the driving unit is arranged on the top of the support platform 1. The driving unit includes: a double-stroke cylinder 51. The double-stroke cylinder 51 is arranged on the top of the support platform 1, and the output end of the double-stroke cylinder 51 is connected to the support frame 3 to drive the support frame 3 to move horizontally.

[0034] Specifically, as Figures 1 - 5 shown in the figure, the jacking frame 7 is located on the top of the support frame 3; the four rollers 8 are respectively arranged on the two outer side walls of the jacking frame 7 and are located on the top of the four support blocks 4; the four guide rods 6 are arranged at the four corners of the jacking frame 7; the four linear bearings 91 are arranged on the support platform 1 and are respectively sleeved on the four guide rods 6.

[0035] Furthermore, as Figures 1 - 5 shown in the figure, a horizontally pushable variable stroke jacking mechanism according to an embodiment of the present utility model further includes: a bottom limit block 92. The bottom limit block 92 is arranged on one side of the bottom of any one of the support blocks 4 and is used for limiting the roller 8.

[0036] Furthermore, as Figures 1 - 5 shown in the figure, a horizontally pushable variable stroke jacking mechanism according to an embodiment of the present utility model further includes: a top limit block (not shown in the figure). The top limit block is arranged on one side of the top of any one of the support blocks 4 and is used for limiting the roller 8.

[0037] Working principle:

[0038] Initially, the roller 8 is located on the third support surface at the top of the support block 4. Then, the workpiece to be waited for is placed on the padding rack. When only one-time height lifting is required, the double-stroke cylinder 51 operates to drive the support frame 3 to move, thereby driving the four support blocks 4 to move on a pair of guide rails 2. During the movement, through the inclined surface between the third support surface and the second support surface, the roller 8 climbs from the third support surface to the second support surface. At the same time, the lifting frame 7 moves upward through the four guide rods 6 on the four linear bearings 91 to achieve one-time lifting of the workpiece.

[0039] When two-time height lifting is required, the double-stroke cylinder 51 operates again. By the operation of the double-stroke cylinder 51, the support frame 3 is driven to move, thereby driving the four support blocks 4 to move on a pair of guide rails 2. During the movement, through the inclined surface between the second support surface and the first support surface, the roller 8 climbs from the second support surface to the first support surface. At the same time, the lifting frame 7 moves upward through the four guide rods 6 on the four linear bearings 91 to achieve two-time lifting of the workpiece.

[0040] Above, with reference to Figures 1 - 5 A lifting mechanism with a horizontally pushed variable stroke according to an embodiment of the present invention is described, having the following beneficial effects:

[0041] 1. Solve the horizontal problem of the tray after lifting.

[0042] 2. The whole set of devices is a pure mechanical structure, with low cost and low operating cost.

[0043] 3. It is easy to achieve standardized application, and the size can be changed according to the actual product size.

[0044] 4. Good compatibility, capable of compatible with two lifting heights and reducing the workload of compatible debugging.
