A spring installation tool for variable oil pump

Abstract

The invention discloses an installing tool for a variable oil pump spring. The other end of a screw movably penetrates through the side wall of a fixing frame. The screw is in threaded connection withan abutting block. A plurality of first telescopic rods are fixedly connected to the side wall of the abutting block, the other ends of the first telescopic rods are fixedly connected to the inner side wall of the fixing frame, a limiting frame and a cover plate are of a combined structure, and the oil pump spring can be prevented from being bounced off in the compression process through cooperative work of three components. In the electrification state, an electromagnet generates magnetism and can attract a lock rod, the lock rod cannot fall down, and through a combined structure of a partition plate and a push-pull plate, the outside lock rod can be prevented from continuously entering the fixing frame through a feeding rod; and thus, the device can achieve the effect of convenient andaccurate installation, and can also achieve the effect of safety protection.

Description

technical field [0001] The invention relates to the technical field of variable variable oil pumps, in particular to a spring installation tool for variable variable oil pumps. Background technique [0002] Regarding the installation of the current variable oil pump spring, there are the following problems: [0003] 1. The adjustment spring of the current variable displacement pump is manually assembled; [0004] 2. The assembly is difficult. The spring needs to be compressed and then installed in the card slot. The elastic force is relatively large and it is difficult to compress; [0005] 3. During the spring installation process, it is easy to bump and scratch the edge of the card slot; [0006] 4. It is easy to hurt the operator. When the spring is installed, it needs a lot of force to compress the spring. The edge of the card slot is relatively sharp, and it is easy to scratch the hand when the operation is improper; [0007] 5. The installation quality is low, and t...
