More than the margin of tolerance of regulation, i.e. its precision is low, product quality extremely unstable.During using, owing to precision is low, cause
The conformability of central shaft and axle sleeve is deteriorated, and even causes and can not use.
The axle sleeve of existing angle regulating device for seat of vehicle on the market, its foursquare length of side of axle sleeve convex shoulder typically requires it is little
In 11-1mm, the convex shoulder square precision that good businessman produces typically also only reaches no more than 11-0.5mm, this not only adds
The difficulty that axle sleeve coordinates with respective center axle, also increases the abrasion between axle sleeve and central shaft.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of axle sleeve for angle regulating device for seat of vehicle, solves existing
There is technology axle sleeve to coordinate with axle easily to come off, and specification tolerance is big, the little problem of precision.
For reaching above-mentioned purpose, the following technical scheme of the utility model offer:
A kind of axle sleeve for angle regulating device for seat of vehicle, including sleeve body, the circumference of the outer surface of described sleeve body
Direction is provided with positioning convex shoulder and coordination convex shoulder, and described positioning convex shoulder and coordination convex shoulder are along the axial side of described sleeve body
To stepped, described sleeve body in axial direction have axis hole, described axis hole is square, and described positioning convex shoulder is side
Shape.
More preferably: described axis hole is square axis hole.
More preferably: the described foursquare length of side is not more than 7+0.05mm.
More preferably: the described foursquare length of side is not more than 7+0.02mm.
More preferably: described positioning convex shoulder is square, described coordination convex shoulder is that chamfering is square.
More preferably: described positioning convex shoulder is square.
More preferably: the described foursquare length of side is not more than 11-0.1mm.
More preferably: the described foursquare length of side is not more than 11-0.05mm.
More preferably: the material of described axle sleeve is steel.
The beneficial effects of the utility model are:
The utility model is high for the specification precision of the axle sleeve of angle regulating device for seat of vehicle, improves axle sleeve and central shaft
Conformability, its use fit rate up to 98%, meanwhile, sleeve body in axial direction have square opening and prism, can be effectively
Prevent central shaft from rotating in hole, and be not easy to come off.
Brief description
Fig. 1 is the front view structure schematic diagram for the axle sleeve of angle regulating device for seat of vehicle for the utility model；
Fig. 2 be Fig. 1 look up structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As depicted in figs. 1 and 2, a kind of axle sleeve for angle regulating device for seat of vehicle, including sleeve body 1, at sleeve body 1
The circumferential direction of outer surface be provided with positioning convex shoulder 2 and coordination convex shoulder 3, and positioning convex shoulder 2 and coordination convex shoulder 3 are along described axle sleeve
The axial direction of body 1 is stepped, described sleeve body 1 in axial direction have an axis hole 4, described axis hole 4 is square, institute
It is square for stating positioning convex shoulder 2.
Wherein: the square of axis hole 4 is square, and the foursquare length of side of this axis hole is not more than 7+0.05mm, is further:
This foursquare length of side is not more than 7+0.02mm, i.e. this axis hole foursquare length of side tolerance can be accurate to positive 0.02mm.
Positioning convex shoulder 2 is square, and coordination convex shoulder 3 is square for chamfering.
Positioning convex shoulder 2 is square, and this foursquare length of side is not more than 11-0.1mm, further: this foursquare limit
Fail to grow up in 11-0.05mm, i.e. the foursquare length of side tolerance of this positioning convex shoulder can be accurate to positive 0.05mm.
More preferably: the material of described axle sleeve is steel.
The utility model is made by following preparation method for the axle sleeve of angle regulating device for seat of vehicle:
A () blanking: be placed on the wire rod rolled product got ready on feeder equipment, feeder equipment sends into wire rod rolled product in cold headers
Blanking；
(b) axle sleeve processing by several times: select the direct cold-heading molding of multistage cold former, configure three width processing moulds in cold headers
Tool, by three cold-headings extruding, b1) extruding of cold-heading for the first time: in cold headers, configure the first processing mold, carry out with cold headers
