Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinders, in particular to an oil cylinder guide device with an anti-collision function. Background Art

[0002] Cylinder, usually referred to as hydraulic cylinder, is a hydraulic component used to convert hydraulic energy into mechanical energy. The basic structure of the cylinder includes cylinder barrel, cylinder head, piston and piston rod, and sealing device. These components work together to enable the cylinder to perform linear reciprocating motion or swing motion. In mechanical systems, cylinders are widely used in various equipment, such as cranes, excavators, presses, injection molding machines, etc., to achieve efficient power transmission and motion control.

[0003] For example, a hydraulic cylinder guide device with the authorization announcement number "CN209936968U" cooperates with the cylinder, guide plate, slide bar, second bevel gear, first bevel gear, spring, handle, pull rod, pressure plate, support plate, thin wire, ring plate, reset spring, rack, gear, guide rod, support plate and spring net. The cylinder squeezes the guide plate to move, the guide plate drives the slide bar to slide, and the slide bar drives the second bevel gear to slide on the first bevel gear. It can match cylinders with different radii for guidance, with a simple structure and convenient operation. However, the hydraulic cylinder guide device guides the piston rod of the cylinder through the thin wire. Due to the strong force of the cylinder, the thin wire is easily damaged. The cylinder needs to be closed and the thin wire needs to be repaired. The maintenance takes a long time, thereby reducing the work efficiency. At the same time, the hydraulic cylinder guide device has no anti-collision function. When the cylinder is working and directly contacts with an object, the cylinder is subjected to a large impact force, which is easy to damage the cylinder. The operator needs to frequently inspect the cylinder, which reduces the service life of the cylinder. Utility Model Content

The oil cylinder needs to be closed and the thin wire needs to be repaired. The repair takes a long time, thereby reducing the working efficiency. At the same time, the hydraulic cylinder guide device has no anti-collision function. When the oil cylinder is working and directly contacts with an object, the oil cylinder is subjected to a large impact force, which easily causes damage to the oil cylinder. The operator needs to frequently inspect and repair the oil cylinder, which reduces the service life of the oil cylinder. Therefore, a cylinder guide device with an anti-collision function is proposed.

[0025] Refer to the attached Figure 4 and attached Figure 6

[0026] The auxiliary fixing mechanism 6 includes a shell 601, which is rotatably connected to the turning handle 602 through a bearing, a threaded rod 603 is fixedly connected to the end of the turning handle 602, the threaded rod 603 is rotatably connected to the shell 601 through a bearing, the threaded rod 603 is connected to the slider 604 through a thread, the surface of the slider 604 is slidably connected to the slide groove processed on the shell 601, two cross bars 605 are fixedly connected to the surface of the slider 604, the two cross bars 605 are slidably connected to the shell 601 through through holes, the turning handle 602 is rotatably connected to the piston rod 3 through a bearing, the two cross bars 605 are slidably connected to the piston rod 3 through through holes, the rotation of the turning handle 602 drives the threaded rod 603 to rotate, thereby driving the slider 604 to slide along the slide groove processed on the shell 601, and the sliding of the slider 604 drives the two cross bars 605 to slide along the through holes processed on the shell 601.

[0027] Working principle:

[0028] When using a cylinder with anti-collision and guide functions:

[0029] Preparation process:

[0030] The operator first inserts the moving block 4 into the groove processed on the piston rod 3, and then turns the left handle 602 clockwise. The rotation of the handle 602 drives the threaded rod 603 to rotate, thereby driving the slider 604 to slide along the groove processed on the shell 601. The sliding of the slider 604 drives the two cross bars 605 to slide to the right along the through holes processed on the shell 601. Similarly, the operator turns the right handle 602 counterclockwise to drive the two cross bars 605 to slide to the left. When the surfaces of the four cross bars 605 are tightly against the inner walls of the grooves processed on the moving block 4, the operator stops turning the handle to quickly fix the moving block 4. When the piston rod 3 contacts an object, the elasticity of the rubber pad 5 can be used to prevent the piston rod 3 from collision. The operator does not need to frequently inspect the cylinder, thereby increasing the service life of the cylinder.

[0031] Piston rod guiding process:

[0032] Start the cylinder body 1 and connect the external power supply. When the piston rod 3 is extended, it drives the second telescopic rod 204 to slide along the slide groove processed on the first telescopic rod 203. When the second telescopic rod 204 completely slides out along the slide groove processed on the first telescopic rod 203, it drives the first telescopic rod 203 to slide along the slide groove processed on the sleeve 202. The piston rod 3 can be supported by the two second telescopic rods 204, the first telescopic rod 203 and the sleeve 202, and the piston rod 3 will not be offset. It can guide the piston rod 3. The second telescopic rod 204, the first telescopic rod 203 and the sleeve 202 are not easy to be damaged, and the operator does not need to stop the machine frequently for maintenance or replacement, thereby improving work efficiency.
