A leaf spring stack assembly

Abstract

The present invention relates to the technical field of assembly of auto parts, in particular to a leaf spring stacking assembly, which includes a stacking platform, a stacking tube, a nut screwing mechanism and a straightening mechanism, and two supports are symmetrically arranged on the stacking platform The two support columns are provided with two symmetrical bending cylinders on the side away from each other, and the stacking tube is vertically arranged under the stacking platform, and is also located at the center of the four bending cylinders. The nut mechanism is located on the top of the stacking table and directly above the stacking tube. The side of the nut screwing mechanism is equipped with a lifting pole connected to it. The top of the stacking tube can pass through the nut screwing mechanism from bottom to top. The straightening mechanism is located in the middle of the two bending cylinders, and is also between the two support columns. The other two bending cylinders are respectively equipped with a limit plate on the side far away from each other. A detection platform is provided, and a material pulling mechanism is provided under the detection platform, and the present invention can reduce the labor intensity of labor.

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.
