Abstract
The utility model relates to a rivet used in brake band and clutch-lamellae. The rivet adopts copper or middle and low carbon steel wires and is made through automatic cold heading. The utility model is composed of a rivet rod part (4), an end face of the rivet head part (2), and a semi-hollow circular hole of the rivet rod part (1), and is characterized in that the end face of the rivet head part is provided with a drill hole guiding eye that is homocentric with the rivet rod part. The function of the guiding eye is that the guiding eye can be used for drill hole positioning when the rivet is removed. When using the utility model, one just needs to drill through the head part of the rivet by using the electric drill to collimate the guiding eye, thus realizing the goal of faster brake band and clutch-lamellae with high speed. The utility model has a simple structure, low processing cost and convenient use.
Description
Technical field
The utility model relates to a kind of rivet, relates in particular to a kind of rivet that is used on vehicle brake band, the clutch plate.
Background technique
At present, the rivet on known vehicle brake band, the clutch plate mainly contains GB875-86 thin flat head socket shank rivet and GB874-86 120 degree countersunk head semi tubular rivet.The brake strap rivet mainly contains materials such as aluminium, copper, steel, and aluminum rivet is low than copper, Steel Rivet intensity, changes easily, accounts for the market mainstream, and copper, Steel Rivet changes difficulty because of it and cost Gao Erwei promotes the use of.Rivet on the clutch plate then requires high temperature resistant, and mainly based on copper, two kinds of materials of steel, but it changes difficulty, and clutch plate is damaged the back to change clutch assembly, has caused unnecessary waste.
Summary of the invention
The purpose of this utility model just provides a kind of defective and deficiency that can overcome above rivet existence, adopt copper or in, the automatic cold-heading of low carbon steel wire rod forms, intensity height, riveted joint are reliably changed a kind of rivet that conveniently is used on vehicle brake band, the clutch plate.
The technical solution of the utility model is achieved in that a kind of rivet, comprises rivet bar portion, rivet head end face and rivet bar portion semi-hollow circular hole, a boring is set at rivet head end face center draws eye, and a center and rivet bar portion centres are drawn in this boring.Boring is drawn eye and is conical bore or spherical circular hole or cylindrical hole.
The utility model has the advantages that: make simply, can change brake strap, clutch plate quickly and easily, save material, cost of production is low.
Description of drawings
Fig. 1 is the utility model structural representation; Fig. 2 is Figure 1A-A sectional view;
Fig. 3 is the worm's eye view of Fig. 1; Fig. 4 is the plan view of Fig. 1.
Embodiment
Shown in Fig. 1,2,3,4, a kind of rivet, comprise rivet bar portion 4, rivet head end face 2 and rivet bar portion semi-hollow circular hole 1, one boring is set in the rivet head end face 2 of countersunk head semi-hollow in the heart draws eye 3, the center and rivet bar portion 4 centres of eye 3 are drawn in boring, boring is drawn eye 3 and is conical bore, or spherical circular hole or cylindrical hole.Be arranged on the 2 supercentral borings of rivet head end face and draw the external diameter and the similar conical bore of rivet bar portion 4 diameters that eye 3 adopts holes, it is concentric with rivet bar portion 4 that a center of 3 is drawn in this boring.Owing to adopt the eye that draws of conical bore, the thickness of rivet head plays the effect of drill bit location than the Kong Gengneng that adopts spherical circular hole, cylindrical hole or other shape.When changing brake strap, clutch plate, drill brake strap, the clutch plate that rivet head can effectively be changed breakage quickly as long as draw eye 3 with the boring on the drill bit rivet end face 2 as needs.
Claims (3)
1. a rivet comprises rivet bar portion (4), rivet head end face (2), rivet bar portion semi-hollow circular hole (1), it is characterized in that: a boring is set in rivet head end face (2) in the heart draws eye (3).
2. a kind of rivet according to claim 1 is characterized in that: be arranged on center and rivet bar portion (4) centres that eye (3) is drawn in the supercentral boring of rivet head end face (2).
