Steel plate spring piling-up assembly

Abstract

The invention relates to the technical field of car part assembling, in particular to a steel plate spring piling-up assembly. The assembly comprises a piling-up table, a piling-up pipe, a nut twisting mechanism and a correcting mechanism. Two bearing columns are symmetrically arranged on the piling-up table, the sides, away from each other, of the two bearing columns are provided with two symmetric bending air cylinders, the piling-up pipe is vertically arranged below the piling-up table, and located among the four bending air cylinders, the nut twisting mechanism is located on the top of thepiling-up table and is located over the piling-up pipe, a lifting pole in transmission connection with the nut twisting mechanism is arranged beside the nut twisting mechanism, the top end of the piling-up pipe penetrates through the nut twisting mechanism from bottom to top, the correcting mechanism is located on centers of the two bending air cylinders, and located between the two bearing columns, the sides, away from each other, of the other two bending air cylinders are each provided with a limiting disc, a detection table is arranged outside one side of the piling-up table, and a pullingmechanism is arranged below the detection table. Labor intensity of a worker can be reduced.

Description

technical field [0001] The invention relates to the technical field of assembly of auto parts, in particular to a stacked leaf spring assembly. Background technique [0002] Leaf spring Leaf spring is the most widely used elastic element in automobile suspension. It is composed of several alloy spring sheets of equal width but unequal length (thickness can be equal or unequal) (stacked, one piece pressed It is stacked one by one, and the length of a group of leaf springs changes from top to bottom (from long to short) to form an approximately equal-strength elastic beam. [0003] Each leaf spring is in the shape of an arc, and there is a center hole in the center. The significance of the center hole is that when stacking multiple leaf springs, bolts and nuts are used to fix them through the center hole, and one of the leaf springs is fixed in advance. Two U-shaped clips are installed. After the U-shaped clips are stacked with multiple leaf springs, they need to be closed wi...

[0003] Each leaf spring is in the shape of an arc, and there is a center hole in the center. The significance of the center hole is that when stacking multiple leaf springs, bolts and nuts are used to fix them through the center hole, and one of the leaf springs is fixed in advance. Two U-shaped clips are installed. After the U-shaped clips are stacked with multiple leaf springs, they need to be closed with a hammer. This operation will assist in fixing the multiple leaf springs; the weight of the leaf spring itself is not light. An elastic beam needs at least 6 pieces of leaf springs, and the traditional stacking work is done manually, which is very labor-intensive, such as: knocking U-shaped clips, flipping elastic beams (stacked by multiple leaf springs), Transfer the elastic beam to the detection platform for pressure testing and so on. The purpose of turning over the elastic beam is to install the nut manually on the side or above the leaf spring in order to facilitate the operation. In other words, when the leaf springs are stacked, one is to place them vertically, that is, the center hole faces the manual direction, so such a posture is not conducive to the material transfer after completion, and can only be carried by hand.
