Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1, the lifter for the mold workbench of the automobile of the embodiment includes an oil pump 1 installed on a main oil path 3, the oil pump 1 is driven by a motor 2 to operate, a check valve 4 is installed on an output oil path of the oil pump 1, the output oil path of the check valve 4 is divided into three branches, namely a first branch 5, a second branch 6 and a third branch 7, wherein a pressure gauge 8 is installed on the first branch 5, an overflow valve 9 is installed on the third branch 7, a two-position four-way solenoid valve 10 is installed on the second branch 6, the two-position four-way solenoid valve 10 leads out a first oil path 11 and a second oil path 12, the first oil path 11 is divided into four first branch sub oil paths 13, the first branch sub oil paths 13 are respectively connected with upper cavity oil ports 14 of four oil cylinders 16, the second oil path 12 is divided into four second branch sub oil paths 15, the second branch sub oil paths 15 are respectively connected with lower cavity oil ports 17 of the four oil cylinders 16, the movable ends of the four oil cylinders 16 are respectively contacted with the four corners of the lower surface of the workbench trolley;

in order to facilitate the replacement of the pressure gauge 8, a valve 18 for controlling the conduction or the closing of the first branch is arranged on the first branch 5;

in order to achieve a better pressure detection effect, the pressure gauge 8 is an electric contact pressure gauge.

The working principle is as follows: the motor 2 drives the oil pump 1 to work, oil pumped by the oil pump 1 supplies oil to an upper oil cavity 14 of the oil cylinder 16 through the one-way valve 4 and the two-position four-way electromagnetic valve 10, the trolley on the workbench falls, and when the lifting force reaches the pressure set by the electric contact pressure gauge 8, the motor 2 stops rotating. The pressure of the system is maintained by the one-way valve 4, so that the lifting force of the workbench trolley is ensured. When the pressure gauge 8 detects that the lifting force of the workbench is lower than the set pressure, the motor 2 automatically rotates to supply oil to the oil cylinder 16. When the workbench trolley needs to be lifted, the electromagnet YAI of the two-position four-way electromagnetic valve 10 is electrified, and hydraulic oil of the upper cavity oil port 14 of the oil cylinder 15 returns to the oil tank through the two-position four-way electromagnetic valve 10. The oil cylinder 16 drives the working platform trolley to rise, the working platform trolley is driven out of the working platform through the pneumatic motor, and the pressure of the whole system is adjusted through the overflow valve 9.

The landing gear of this embodiment can keep pressure stable after realizing that the hydro-cylinder 16 expansion end descends, realizes automatic pressurize pressure compensation. The lifting speed of the trolley of the workbench is improved by setting the flow of the oil pump 1. After the movable end of the oil cylinder 16 descends, the motor 2 stops rotating, and energy conservation is realized.

The lifting device of the embodiment is changed into a hydraulic system from a pneumatic motor, the lifting workbench trolley is reduced from the original 30 minutes to 3 minutes, the working efficiency of the equipment is improved, the failure rate is low, the maintenance cost and the maintenance time are reduced, the lifting device is simple, convenient, safe and reliable, and the income of enterprises can be increased by more than 10 ten thousand yuan each year.

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