Abstract
The utility model relates to a substitute structure of a central hole of a plate spring, belonging to the technical field of plate springs; the plate spring is provided with a positioning assembly, the positioning assembly and the plate spring are integrally formed, and the positioning assembly is formed by punching through a punch; the positioning component is characterized in that a counter bore is formed by the inner side of one side of the plate spring in a concave mode, a positioning block is formed by the outer side of the other side of the plate spring in a convex mode, and the shape of the positioning block is matched with that of the counter bore. The utility model discloses a locating component replaces former centre bore, central bolt to the positioning action of leaf spring, directly avoids the leaf spring because of the cracked phenomenon of central defect, makes steel sheet life prolong greatly.
Description
Technical Field
The utility model belongs to the technical field of the leaf spring, especially, relate to an alternative structure of leaf spring centre bore.
Background
The central position of each spring leaf of the conventional plate is provided with a central hole, and a central bolt of the plate spring assembly penetrates through the central holes to fix the relative positions of the plates. The punching or drilling process can cause the fracture of the metal streamline of the steel plate, the center hole of the plate spring is used as a defect of the plate spring, and the fracture position of the plate spring is always at the center hole in the actual use process.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an alternative structure of leaf spring centre bore to there is the technical problem of a great deal of defect in setting up the centre bore on solving the leaf spring piece.
In order to achieve the above object, the utility model discloses an alternative structure of leaf spring centre bore concrete technical scheme as follows:
a replacement structure of a central hole of a leaf spring is characterized in that a leaf spring is provided with a positioning assembly, the positioning assembly and the leaf spring are integrally formed, and the positioning assembly is formed by punching through a punch;
the positioning component is characterized in that a counter bore is formed by the inner side of one side of the plate spring in a concave mode, a positioning block is formed by the outer side of the other side of the plate spring in a convex mode, and the shape of the positioning block is matched with that of the counter bore.
Furthermore, the cross sections of the counter bores and the positioning blocks are isosceles trapezoids.
Furthermore, a chamfer is arranged at the joint of the counter bore and the plate spring, and a chamfer is arranged at the joint of the positioning block and the plate spring.
Further, the depth A of the counter bore is smaller than the thickness B of the plate spring.
Further, the height C of the positioning block is smaller than the thickness B of the plate spring.
Further, the height C of the positioning block is smaller than the depth A of the counter bore.
The utility model discloses an alternative structure of leaf spring centre bore has following advantage: the positioning assembly is adopted to replace the positioning action of the original center hole and center bolt on the plate spring, so that the phenomenon that the plate spring is broken due to center defect is directly avoided, and the service life of the steel plate is greatly prolonged;
this locating component adds man-hour because of the drift need not wholly pass the steel sheet, avoids the friction with the steel sheet, and drift life extension reduces product manufacturing cost, improves production efficiency, improves the whole competitive advantage of product on market.

Fig. 2 is a top view of fig. 1.
Fig. 3 is a partial cross-sectional view of an alternative configuration of a leaf spring center hole.
The notation in the figure is: 1. a plate spring; 2. a positioning assembly; 201. a counter bore; 202. positioning blocks; 3. and (6) chamfering.
Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings for an alternative structure of the center hole of the plate spring.
The utility model discloses a new construction that puts at former centre bore and beat the convex closure replaces centre bore, central bolt to the positioning action of leaf spring. As shown in the following figure 1, each sheet is positioned by matching the concave pits and the convex hulls, so that the relative position of the steel plates cannot be displaced. The depths of the concave pits and the convex hulls are adjusted according to the thicknesses of different steel plates.
As shown in fig. 1-3, an alternative structure of a leaf spring center hole is provided, a leaf spring 1 is provided with a positioning component 2, the positioning component 2 is integrally formed with the leaf spring 1, and the positioning component 2 is formed by punching through a punch;
one side of the positioning component 2 is sunken towards the inner side of the plate spring 1 to form a counter bore 201, the other side of the positioning component is protruded towards the outer side of the plate spring 1 to form a positioning block 202, and the shape of the positioning block 202 is matched with that of the counter bore 201.
In this embodiment, the cross sections of the counter bore 201 and the positioning block 202 are isosceles trapezoids.
In the present embodiment, a chamfer 3 is provided at a position where the counterbore 201 meets the plate spring 1, and a chamfer 3 is provided at a position where the positioning block 202 meets the plate spring 1.
In the present embodiment, the depth a of the counterbore 201 is less than the thickness B of the leaf spring 1.
In the present embodiment, the height C of the positioning block 202 is smaller than the thickness B of the plate spring 1.
In the present embodiment, the height C of the positioning block 202 is smaller than the depth a of the counterbore 201.
It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are intended to be covered by the present invention.
