Pressing machine for plate spring guide arm

Abstract

The invention discloses a plate spring guide arm pressing machine which is characterized in that the plate spring guide arm pressing machine comprises a machine body, a machine base and a plate spring fixing clamp, a main pressing rod is arranged on a connecting rod, a left pressing rod is arranged on a left fixing plate, and a right pressing rod is arranged on a right fixing plate; a first left pressure maintaining plate and a second left pressure maintaining plate are arranged on the left side of the clamp body, and a first right pressure maintaining plate and a second right pressure maintaining plate are arranged on the right side of the clamp body. The plate spring fixing clamp is provided with the plate spring fixing groove, the limiting plate is arranged on the plate spring fixing groove, the clamping groove is formed below the limiting plate, and the end of the plate spring is clamped in the clamping groove, so that the plate spring is in a stable state, and pressure maintaining of the plate spring is achieved. The pressure maintaining cost of the plate spring is reduced, and the ex-factory qualified rate of the plate spring is improved.

Description

technical field [0001] The invention relates to the technical field of leaf spring sorting machines, in particular to a press machine for a leaf spring guide arm. Background technique [0002] Leaf spring is the most widely used elastic element in automobile suspension. It is composed of several alloy spring pieces of equal width but unequal length (thickness can be equal or not). An approximately equal strength elastic beam. The leaf spring beam is a leaf spring with only one piece, mostly used to support the car engine and buffer the impact damage to the engine. [0003] Leaf spring beams are generally installed on the car frame, and the space is limited, so OEMs have high requirements for the size of the leaf spring beams. The hole of the leaf spring is very important for the installation of the leaf spring. If the size of the hole exceeds the tolerance range, it is difficult to install the leaf spring on the car frame, and the leaf spring needs to be reworked, which ma...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a press for the guide arm of the leaf spring to solve the problem of manually maintaining the pressure of the leaf spring or not maintaining the pressure of the leaf spring in the above background technology. Manually maintaining the pressure of the leaf spring requires a lot of manpower. If the pressure is not maintained, the plate If the size of the spring does not meet the requirements, the leaf spring cannot be installed, and more leaf springs need to be reworked, resulting in a large amount of rework and a low pass rate of the product
