Further, both the rotary cylinders are located at the rear side of the platen.

Further, the tool still includes: and one leaf of the hinge is fixed with the adsorption plate, and the other leaf of the hinge is fixed with the pressing plate.

Furthermore, the number of the hinges is two, and the two hinges are separated from each other along the left-right direction.

Further, the upper surface of adsorption plate has the boss, and the lower surface has the recess, the upper surface to the boss is run through from the top surface of recess to the adsorption hole.

After the technical scheme is adopted, the utility model has the effects that:

1. above-mentioned tool changes revolving cylinder into and fixes a position, and revolving cylinder itself can not occupy the space of clamp plate upper and lower direction, is favorable to reducing holistic height for the CCD camera can accurately focus, surveys the position of lid behind the cell-phone.

2. The jig saves parts such as the bottom plate, the guide rod, the lifting plate and the like, simplifies the whole structure and reduces the manufacturing cost.

Detailed Description

It is specifically noted that, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise; the meaning of "several" is at least one. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative positional relationship between the components, the movement, and the like in a certain posture, and if the certain posture is changed, the directional indicator is changed accordingly.

The technical solution of the present invention is further described by the following examples:

the utility model provides a jig for CNC (computer numerical control) machining of a rear cover of a mobile phone, which comprises the following components as shown in figure 2: adsorption plate 1, clamp plate 2, locating pawl 3 and revolving cylinder 4, adsorption plate 1 has a plurality of absorption holes 11, and clamp plate 2 has processing opening 21, and clamp plate 2 is located the top of adsorption plate 1 to a plurality of absorption holes 11 all just right with processing opening 21, and revolving cylinder 4's piston rod forms fixedly with locating pawl 3, and locating pawl 3's rotatory orbit passes through the upper surface of clamp plate 2.

When the jig is used, an unmolded mobile phone rear cover (namely a mobile phone rear cover flat plate) can be placed on the adsorption plate 1, the adsorption hole 11 is externally connected with a suction pump, pre-positioning of the mobile phone rear cover is realized through suction force firstly, then the pressing plate 2 is covered on the mobile phone rear cover, the machining opening 21 is right opposite to the machining position of the mobile phone rear cover, and finally the positioning claw 3 is controlled to rotate through the rotary cylinder 4 to be in contact with the upper surface of the pressing plate 2, so that the positioning of the mobile phone rear cover is realized. After the rear cover of the mobile phone is positioned, a CCD camera of the CNC machining equipment detects the specific position of the rear cover of the mobile phone, and the rear cover of the mobile phone is ground, polished and the like through a machining tool.

Specifically, the positioning pawl 3 and the rotary cylinder 4 are both two, and the two rotary cylinders 4 are separated from each other in the left-right direction. Through the mode of two point location, can make the clamp plate 2 compress tightly the effect better.

More specifically, both the rotary cylinders 4 are located on the rear side of the platen 2. Therefore, the mobile phone rear cover can be conveniently placed by a worker, and the blockage is avoided.

Specifically, the tool still includes: one leaf of the hinge 5 is fixed with the adsorption plate 1, and the other leaf is fixed with the pressing plate 2. Make adsorption plate 1 and clamp plate 2 can take place the relative rotation through setting up hinge 5, be favorable to clamp plate 2's accurate positioning.
