DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, this specific implementation adopts the following technical solutions:

[0025] It comprises a base 1 and a lifting platform 2, wherein a lifting guide sleeve 3 is fixedly provided on the base 1, a lifting guide rod 4 is movably inserted into the upper end of the lifting guide sleeve 3, and the lifting platform 2 is fixedly provided on the upper end of the lifting guide rod 4. It also comprises:

[0026] A slave cylinder 5, wherein the slave cylinder 5 is fixedly mounted on the base 1, and an output shaft of the slave cylinder 5 is fixedly mounted on the lower surface of the lifting platform 2;

[0027] The active oil cylinder 6 is fixedly arranged on the base 1, and the active oil cylinder 6 and the driven oil cylinder 5 are connected by a pipeline;

[0028] A mounting frame 11 is mounted above the active oil cylinder 6;

[0029] Transmission arm 8, the transmission arm 8 is rotatably mounted on the mounting frame 11 via a rotating shaft, and a waist-shaped hole 10 is provided on the transmission arm;

[0030] A transmission rod 7, wherein the transmission rod 7 is fixedly arranged on the output shaft of the active oil cylinder 6;

[0031] A guide pin 9 is fixedly provided on the same section of the transmission rod 7 and is movably inserted into the waist-shaped hole 10;

[0032] A spur gear 13, wherein the spur gear 13 is rotatably mounted on the mounting frame 11 via a rotating shaft;

[0033] An arc-shaped rack 12 is fixedly mounted on the transmission arm 8 at one end away from the shaft end, and a spur gear 13 is meshed with the arc-shaped rack 12;

[0034] A drive motor 14 is fixedly mounted on the mounting frame 11, and an output shaft of the drive motor 14 is in driving connection with a shaft end of the spur gear 13;

[0035] The support frame 15 is fixedly mounted on the arc-shaped rack 12, and the lower end of the support frame 15 is fixedly mounted on the transmission arm 8;

[0036] The screw rod 18 is screwed on the outer wall of the active oil cylinder 6 through a bearing, and the screw rod 18 is screwed through the mounting bracket 11 through a thread;

[0037] A support guide sleeve 17, wherein the support guide sleeve 17 is fixedly mounted on the mounting frame 11;

[0038] The support guide rod 16 is movably inserted into the support guide sleeve 17 , and one end of the support guide rod 16 is fixedly set on the base 1 , and the other end of the support guide rod 16 is fixedly set on the upper surface of the active oil cylinder 6 .

[0039] When using this device, the workpiece is placed on the lifting platform 2 and the lifting and lowering movement of the lifting platform 2 is used to feed the workpiece. The driving motor 14 drives the spur gear 13 to rotate back and forth, so that the spur gear 13 pushes the arc rack 12 to move, and the arc rack 12 drives the transmission arm 8 to swing. When the transmission arm 8 swings downward, the transmission arm 8 pushes the transmission rod 7 downward through the guide pin 9, and the transmission rod 7 pushes the piston of the active cylinder 6 to descend, so that the oil in the active cylinder 6 is connected through the pipeline to drive the piston in the driven cylinder 5 to move upward, and the driven piston pushes the lifting platform 2 upward, and vice versa. When the guide pin 9 moves toward the side close to the shaft end of the transmission arm 8, the amplitude of the up and down swinging of the transmission arm 8 and the transmission rod 7 is reduced, and the amplitude of the up and down movement of the lifting platform 2 is reduced. When the guide pin 9 moves toward the side of the arc-shaped rack 12 on the transmission arm 8, the amplitude of the up and down movement of the transmission arm 8 and the transmission rod 7 is increased, and the amplitude of the up and down movement of the lifting platform 2 is increased.

[0040] Compared with the prior art, the beneficial effects of the present invention are:

[0041] This device is provided with a transmission arm 8 that swings up and down, and then realizes the transmission connection between the transmission arm 8 and the piston of the active cylinder 6 through the transmission rod 7. The active cylinder 6 and the driven cylinder 5 are hydraulically transmitted to realize the movement of the lifting platform 2 by the driven cylinder 5, and the transmission ratio is set on an adjustable and movable mounting frame 11. The position of the transmission ratio is adjusted by the mounting frame 11, so that the transmission arm 8 can adjust the up and down movement amplitude of the transmission rod 7 while the swing amplitude remains unchanged, thereby realizing the adjustment of the up and down movement amplitude of the lifting platform 2.

[0042] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
