Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. 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.

The device for circularly reversing the oil pump handle provided by the embodiment aims to reverse the oil pump handle 20 and needs to circularly reverse, the oil pump 10 is arranged in a frame wheel bridge at an inclined plane, the schematic diagram is shown in fig. 1, and the motion track of the oil pump handle 20 is shown in fig. 2.

There are two problems to be solved: 1. the problem of the motion track of the handle is solved; 2. the relative position of the device and the handle is determined and the mounting position of the device on the wheel bridge is determined.

In view of problem 1:

the device that this embodiment provided includes electric putter 1, transfer line 2, push rod guide rail 3, electric putter 1 installs in oil pump handle 20 pivot below, is connected with oil pump handle 20 through transfer line 2, and 1 the place ahead of electric putter is provided with push rod guide rail 3 for it is spacing to electric putter 1, prevents that electric putter 1 from rocking in the motion process, makes the atress even.

In this embodiment, the transfer line 2 is the setting of buckling, and the both ends of transfer line 2 are articulated with electric putter 1 and oil pump handle 20 through the round pin axle respectively, and the bending point rotates and installs at oil pump handle 20 pivot center, and the distance of bending point center to with oil pump handle 20 pin joint equals the turning radius of oil pump handle 20.

In this embodiment, the push rod guide rail 3 is disposed coaxially with the electric push rod 1, and is disposed outside the electric push rod 1 and located at the maximum stroke of the electric push rod 1.

In this embodiment, the center of the push rod guide rail 3 is provided with a long hole along the length direction.

For problem 2:

the device also comprises a three-dimensional coordinatometer (not shown in the figure), which is arranged on the wheel bridge, measures the spatial relative positions of the existing bolt and the handle to form a spatial coordinate, and determines the mounting hole position of the device and the position of the rotating shaft center of the oil pump handle 20 based on the spatial relative positions.

The oil pump handle circulation reversing device is formed by combining a specially designed mechanical structure and an electric push rod in a matching mode. Can realize reciprocating circular motion and overcome the problem that a common motor gear or belt structure is not applicable.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
