Description
Technical field
The present invention relates to a kind of processing and positioning device, refer more particularly to a kind of wheel lip processing and positioning device.
Background technology
Traditional wheel lip positioner is externally embedded type Pneumatic floating device, positioned by junction wheel lip outer face being connected to locating surface and paw, but adopt this kind of positioner, there is following defect: easily cause distortion when the outer broken ends of fractured bone face of wheel lip abuts, weigh wounded, in process, aluminium bits are easily splashed into below floating surface, make product dynamic balancing be deteriorated, beat, first harmonic is deteriorated, and easily produces potential safety hazard.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the invention is to overcome distortion of the prior art, weighs wounded, the defect such as product is beated, balanced differences, provides a kind of positioner of safety and stability.
For achieving the above object, positioner designed by the present invention, comprise a chuck main body, push rod, cylinder, the locating piece being provided with pneumatic induction installation and paw, described push rod is connected on described chuck main body by bearing, described cylinder upper end is fixed on described chuck main body, it is characterized in that: on described chuck main body, radial direction is evenly distributed with three locating pieces and three paws, described locating piece is stepped, locating piece end face is provided with embedded floating pin, and described floating pin is connected in the vertical inner chamber of described locating piece by spring; Described locating piece is also provided with a horizontal inner chamber, and described pneumatic induction installation pneumatic induction installation described in transverse movement in described horizontal inner chamber is moved by the airflow function in described horizontal inner chamber; Described pneumatic induction installation one end can be connected with push rod; Described push rod is positioned at above described cylinder; Described cylinder output is also connected with a movable disk, is provided with movable connecting rod between described chuck main body and described movable disk, and described movable connecting rod upper end is connected with described paw end, and described paw top has projection.
Preferably, the lower end of described projection is provided with paw pad.Being provided with of paw pad is beneficial to compensator or trimmer pressure.
Preferably, described floating pin end face has salient point.
Preferably, described movable connecting rod is connected with movable disk by bearing pin; Described chuck main body is provided with fixed block, and described movable connecting rod is provided with the curve loose slot corresponding with described fixed block.
Preferably, described movable disk is connected with base by spring.
Preferably, described locating piece is in " 7 " type.
Preferably, the rectangular shape of described movable connecting rod.
Beneficial effect of the present invention: the positioner provided is splashed into problem by float safety problem that location can avoid bringing because of angle defect and aluminium bits of the pin that floats, location-plate end face and paw can realize locating up and down in the vertical direction, enhance the stability of processing, avoid distortion and scratch.The present invention not only improves crudy, is also beneficial to safety in production.

Detailed description of the invention
Below by way of specific instantiation, embodiments of the present invention are described, those skilled in the art the content disclosed by this description can understand other advantages of the present invention and effect easily.The present invention can also be implemented or be applied by detailed description of the invention different in addition, and the every details in this description also can based on different viewpoints and application, carries out various modification or change not deviating under spirit of the present invention.
As shown in the figure, positioner, comprise a chuck main body 1, push rod divides bronchus 4 to be connected on chuck main body 1 by bearing, cylinder 5 upper end is fixed on chuck main body 1, and be positioned at push rod and divide below bronchus 4, cylinder output is connected with movable disk 2, spring is provided with between movable disk 2 and holder 3, movable disk edge bearing pin is fixed with the movable connecting rod 8 of rectangular shape, in the middle of movable connecting rod 8, there is curve loose slot, chuck main body 1 is provided with a fixed block and is placed in curve loose slot, movable connecting rod 8 upper end is connected with paw 7 end, paw 7 top has projection, protruding lower end is provided with paw pad 71, paw 7 is in " 7 " type.On chuck main body 1, radial direction is evenly distributed with three locating pieces 6 and three paws 7, and locating piece 6 is stepped, and locating piece end face is provided with embedded floating pin, and the pin that floats is connected by spring to be stated in the vertical inner chamber of locating piece; Locating piece is also provided with a horizontal inner chamber, and the transverse movement in described horizontal inner chamber of pneumatic induction installation, pneumatic induction installation one end can be connected with push rod.Slide up and down by floating pin the size controlling air pressure, equipment is made accurate judgment and whether clamps effectively.
In the course of work, product is placed on three locating surfaces of positioner, the transverse movement of pneumatic induction installation induction clamping product state acts on push rod, push rod acts on cylinder downwards, and cylinder output drives movable disk to move down, and drives movable connecting rod to move down, the paw pad of paw is pressed in wheel antelabium the inner, the inner location of floating on floating pin of wheel lip, when floating pin end face flushes with locating piece end face, the end face of wheel lip inner face and locating piece is fitted completely.Pneumatic induction installation starts effectively.Processed product by this positioner, aluminium bits are not easily splashed into, and product is not easy crimp and scuffing, and processing is stable, production safety.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
