Content disclosed by specification understands other advantages and effect of the utility model easily.
It please refers to Fig.1.It should be clear that structure, ratio, size etc. depicted in this specification institute accompanying drawings, only coordinating
The revealed content of specification, so that those skilled in the art understands and reads, being not limited to the utility model can be real
The qualifications applied, therefore do not have technical essential meaning, the tune of the modification of any structure, the change of proportionate relationship or size
It is whole, in the case where not influencing the effect of the utility model can be generated and the purpose that can reach, should all still fall in the utility model institute
The technology contents of announcement obtain in the range of capable of covering.Meanwhile in this specification it is cited as "upper", "lower", "left", "right",
The term of " centre " and " one " etc. is merely convenient to being illustrated for narration, rather than to limit the enforceable range of the utility model,
Its relativeness is altered or modified, in the case where changing technology contents without essence, when being also considered as the enforceable scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of positioning device, for the parts 3 in differential mechanism production process
It is positioned, which includes with two trepannings being oppositely arranged, the positioning device：Workbench 1 is set to positioning table
On position rotating seat 8, be symmetrically disposed on position rotating seat both sides to penetrating laser sensor 2 and being symmetrically disposed on position rotating
The positioning pin 9 of seat both sides.Preferably, the position rotating platform is set to the center of workbench.
In this present embodiment, the support of the workbench logical ground section material framework, total are made using aluminum section bar frame
Based on, it is easily installed, it is beautiful, it is light.
In this present embodiment, the line of two pairs of lines for penetrating laser sensor and two positioning pins intersects at a bit.It is excellent
The line of selection of land, the line and two positioning pins of two pairs of laser sensors is mutually perpendicular to.
In this present embodiment, which further includes that whether there is in position rotating seat for detecting the parts
Detection switch 4.When detection switch, which detects, has parts on position rotating seat, positioning device is just started to work.
In this present embodiment, which further includes inflatable body 6, which has gas outlet, for blowing off
Liquid around the parts and clast.By the way that inflatable body is arranged, achieve the purpose that clean parts.
In this present embodiment, the position rotating seat is driven by the servo motor 7 for being set to workbench lower end, servo electricity
The output shaft of machine passes through the table top of workbench and is connect with position rotating seat by shaft coupling.Specifically, the position rotating
Seat includes rotor plate 10, rotation axis 11 and crossed roller bearing 12, and servo motor passes through shaft coupling and rotation axis connection, rotation axis
