Abstract
The utility model discloses a wear-resistant flat pull rod joint. The wear-resistant flat pull rod joint comprises a head portion, a through hole, a body portion and a connecting rod; the through hole is formed inside the head portion which is fixed with one end of the body portion; the other end of the body portion is fixed with the connecting rod. The wear-resistant flat pull rod joint has the advantages of being simple in structure, high in accuracy, stable in quality, high in wear resistant performance of the surface, capable of being applied to connecting pieces of automotive turbo scavenging air valves and for tension, compression and rotation in quantity.
Description
Technical field
The utility model relates to a kind of joint, particularly relates to the flat head that sockets of a kind of wear-resisting type.
Background technique
In existing domestic automobile component technology application, for the flat head that sockets of vehicle turbine supercharging scavenging air valve pull bar, all adopt German, Japanese import parts, its complex structure, generally need three to four assembling parts to form, comprise the body that is threaded, the wear-resisting collar, stamping part overcoat, connecting rod etc., its turning respectively, punching press, welding, heat treatment etc. comparatively complicated processing are implemented assembling after becoming single-piece again.In process of production, because complex structure quality is unstable, cost of production is high, be difficult to realize domestication and produce.
Model utility content
Technical problem to be solved in the utility model is to provide the flat head that sockets of a kind of wear-resisting type, its have simple in structure, precision is high, steady quality, surface abrasion resistance high, can widely apply on the link rotating in the connection tension and compression of vehicle turbine supercharging scavenging air valve parts.
The utility model solves above-mentioned technical problem by following technical proposals: the flat head that sockets of a kind of wear-resisting type, it is characterized in that, it comprises head, through hole, body, connecting rod, and through hole is positioned at the inside of head, one end of head and body is fixed, and the other end and the connecting rod of body are fixed.
Preferably, described body be shaped as cylindrical.
Positive progressive effect of the present utility model is: the utlity model has simple in structure, precision is high, steady quality, surface abrasion resistance high, can widely apply on the link rotating in the connection tension and compression of vehicle turbine supercharging scavenging air valve parts.
Accompanying drawing explanation
Fig. 1 is the flat structural representation that sockets head of the utility model wear-resisting type.
Embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the flat head that sockets of the utility model wear-resisting type comprises head 1, through hole 2, body 3, connecting rod 4, and through hole 2 is positioned at the inside of head 1, and head 1 is fixed with one end of body 3, and the other end of body 3 and connecting rod 4 are fixing.Head 1 is circular arc 5 with the bearing of body 3.Being shaped as of body 3 is cylindrical.
The utility model wear-resisting type is flat to be socketed head and adopts the simple structural design of single structure, reaches the application in automobile component significant points, has that dimensional accuracy is high, steady quality, sustainable production in enormous quantities, an advantage such as with low cost.Surface of the present utility model is through carbon or the above nickel phosphor alloy processing of middle phosphorus altogether of plasma carbon nitrogen, and its surface hardness is up to HV1000～1500, and wearing layer thickness is 0.05～0.4mm, makes it to have the connection of rotating wear resistance of higher-strength.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
