Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a cylinder lifting mechanism. Background Technology

[0002] Chinese patent document CN212717483U discloses a cylinder lifting mechanism with guide pillars, including a mounting plate. A cylinder body is fixed to the lower center of the mounting plate. Threaded sleeves are installed at the four corners of the upper end of the mounting plate. A fixing plate is fixedly fitted onto the circumference of the four threaded sleeves. Guide rods are detachably installed inside the threaded sleeves. A top plate is detachably installed at the upper end of the four guide rods. A movable plate passes through the four guide rods. A pad is detachably connected to the lower end of the movable plate. A piston rod is installed on the cylinder body, and the upper end of the piston rod is fixed to the lower center of the pad. This invention provides a cylinder that can operate accurately and stably for extended periods, effectively increasing load capacity and bearing capacity, ensuring accuracy during mold closing, and improving the quality and practicality of workpiece processing.

[0003] However, in the above-mentioned solutions and existing technologies, conventional lifting mechanisms usually utilize vertical cylinder lifting mechanisms. This type of mechanism is relatively simple and easy to install and debug, but it is easily limited by height space. If a horizontal cylinder lifting mechanism is used for lifting and positioning, the length of the lifting mechanism will be increased, which will occupy the installation space of other mechanisms in the case of compact equipment layout, and needs to be improved and optimized. Utility Model Content

[0004] The purpose of this invention is to provide a cylinder lifting mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylinder lifting mechanism, comprising:

[0006] A lifting mechanism mounting base plate, wherein guide linear bearings are fixedly installed at the four corners of the lifting mechanism mounting base plate;

[0007] A lifting plate is provided, with lifting guide rods fixedly installed at the four corners of the bottom end of the lifting plate. The lifting guide rods are movably connected to the guide linear bearings. A lifting assembly is provided on the mounting base plate of the lifting mechanism.

[0008] Preferably, the lifting swing rod fixing seat in the lifting assembly is fixedly mounted on the lifting mechanism mounting base plate, and the lifting swing rod is rotatably mounted on the lifting swing rod fixing seat through the lifting swing rod connecting pin.

[0009] Preferably, a connecting groove is provided on the side wall of the lifting swing arm, a cylinder mounting hinge bracket is fixedly provided at the bottom end of the lifting plate, and an ultra-thin cylinder is fixedly provided at the other output end of the cylinder mounting hinge bracket.

[0010] Preferably, a cylinder adapter block is fixedly provided on the side wall of the output end of the ultra-thin cylinder, and the cylinder adapter block is movably disposed in the connecting groove.

[0011] Preferably, the cylinder adapter block is rotatably connected to the lifting swing rod via a cylinder adapter connecting pin, and the end of the lifting swing rod is rotatably provided with a roller bearing via a roller bearing connecting pin.

[0012] Preferably, a roller bearing lifting block is horizontally fixed at the bottom end of the lifting plate, and the roller bearing lifting block is engaged with the roller bearing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By extending and retracting the output end of the ultra-thin cylinder, cooperating with the rotation of the cylinder mounting hinge bracket, and adjusting the position of the cylinder adapter block within the connecting groove, the lifting swing rod swings to adjust its position. This, in conjunction with the guide rod moving within the guided linear bearing, and the roller bearing at the end of the lifting swing rod rolling along the roller bearing lifting block to adjust its position and lift the lifting plate, the cylinder output end drives the lifting swing rod to swing. The guided linear bearing then converts the swinging motion into linear lifting motion, resulting in a smaller overall volume space occupied by the mechanism, improving the applicability of the device, and meeting practical application needs.

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1-4 The present invention provides the following two preferred embodiments:

[0022] Example 1: A cylinder lifting mechanism, comprising: a lifting mechanism mounting base plate 1, wherein guide linear bearings 2 are fixedly installed at the four corners of the lifting mechanism mounting base plate 1; a lifting plate 4, wherein lifting guide rods 3 are fixedly installed at the four corners of the bottom end of the lifting plate 4, the lifting guide rods 3 being movably connected to the guide linear bearings 2; a lifting assembly is provided on the lifting mechanism mounting base plate 1; and a lifting swing rod fixing seat 5 in the lifting assembly is fixedly installed on the lifting mechanism mounting base plate 1, wherein the lifting swing rod is fixed. A lifting swing rod 7 is rotatably mounted on the base 5 via a lifting swing rod connecting pin 6; a connecting groove 8 is provided on the side wall of the lifting swing rod 7; a cylinder mounting hinge bracket 9 is fixedly mounted at the bottom end of the lifting plate 4; an ultra-thin cylinder 10 is fixedly mounted at the other output end of the cylinder mounting hinge bracket 9; a cylinder adapter block 11 is fixedly mounted on the side wall of the output end of the ultra-thin cylinder 10; the cylinder adapter block 11 is movably mounted in the connecting groove 8; the cylinder adapter block 11 is rotatably connected to the lifting swing rod 7 via a cylinder adapter connecting pin 12.

[0023] In use, the lifting guide rod 3 at the bottom of the lifting plate 4 moves within the guide linear bearing 2, assisting in the guiding and lifting of the lifting plate 4. The ultra-thin cylinder 10 works, causing its output end to retract. At this time, the two ends of the cylinder mounting hinge bracket 9 rotate relative to each other, thereby adjusting the position of the ultra-thin cylinder 10. In conjunction with the cylinder adapter block 11 at the output end of the ultra-thin cylinder 10, the position of the cylinder adapter block 11 is adjusted and rotated within the connecting groove 8, thereby realizing the swing adjustment of the lifting swing rod 7 relative to the lifting swing rod fixing seat 5. The end of the lifting swing rod 7 lifts the lifting plate 4, realizing the lifting and lowering function of the lifting plate 4. The cylinder output end drives the lifting swing rod to swing, and in conjunction with the guide linear bearing 2, the swing is converted into linear lifting motion, making the overall size of the mechanism smaller, improving the applicability of the device, meeting actual needs, and the lifting swing rod 7 is in a vertical state after lifting, making the load capacity of the device stronger.

[0024] Example 2: Based on Example 1, a roller bearing 14 is rotatably mounted at the end of the lifting lever 7 via a roller bearing connecting pin 13. A roller bearing lifting block 15 is horizontally fixed at the bottom end of the lifting plate 4, and the roller bearing lifting block 15 is engaged with the roller bearing 14.

[0025] In use, the roller bearing 14 at the end of the lifting swing rod 7 contacts the roller bearing lifting block 15 fixed at the bottom of the lifting plate 4. When the working output end of the ultra-thin cylinder 10 extends and retracts, the lifting swing rod 7 swings relative to the lifting swing rod fixed seat 5 to adjust its position. During this process, the roller bearing 14 rolls along the roller bearing lifting block 15 to adjust its position, thereby assisting in lifting the lifting plate 4 and improving the stability of the lifting plate 4.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
