Description

CNC engraving device

Technical Field

The utility model belongs to the technical field of the cell-phone accessory processing technique and specifically relates to CNC engraving device.

Background

The metal mobile phone shell is more expensive than the mobile phone shell made of plastic materials, because the mobile phone shell made of glass or plastic can be molded through a mold, and the metal mobile phone shell is carved (milled, drilled) with a metal plate completely through CNC (computer numerical control), not only the material per se is more expensive, but also the processing process is very complicated, the yield is not high due to the plastic, and the price is high.

The existing processing procedures are generally rough milling of the frame and the positioning column, turning, milling of the antenna slot, turning, finish milling of the inner cavity, turning, and finish milling of the outer surface and the side wall. The difficulty here is that the antenna slot is milled and located on the back of the handset, for example, the upper and lower horizontal white lines on the back of the apple handset are the antenna slots filled and sealed with white plastic, which must be enough to bury the antenna and must ensure that the connection strength between the upper and lower ends of the handset housing and the main body is not affected. The existing engraving fixing mechanism has two fixing modes: 1) the inner cavity of the mobile phone shell faces downwards, so that the positioning column is inserted into the positioning groove; 2) the top, side and bottom ends of the handset housing are clamped using clamps.

The former has no vertical positioning, and is easy to jump in vibration; the latter is tightly held but tends to distort the weak antenna slot during the slot milling process due to stresses between the ends and sides.

Disclosure of Invention

To prior art not enough, the utility model provides an kinds of CNC engraving device, the beating or the distortion condition in its reducible cell phone case sculpture course of working.

The technical scheme of the utility model is that:

CNC engraving device, it includes CNC machining center and installs the fixed establishment on CNC machining center workstation, its characterized in that fixed establishment includes base, boss and electromagnet chuck, the base is rectangle stainless steel piece, the welding of base top surface has the boss, the boss cooperation is waited to process the reference column of cell-phone shell inner chamber and has been seted up the through-hole (normally surpass threely), rectangle recess has been seted up to the base bottom surface, just be located rectangle recess top in the base and seted up a plurality of cylindrical recesses, cylindrical recess corresponds the setting with the through-hole and communicates with the through-hole, the electromagnet chuck is inserted in the cylindrical recess, the bottom is gone into to the rectangle recess card for fix the electromagnet chuck, the wiring mouth has been seted up to the wiring end that the bottom corresponds every electromagnet chuck, the welding of base both sides has the installation ear, the installation ear passes through the workstation rigid coupling of bolt and CNC machining center.

, the bottom cover and the base are adhered by strong adhesive.

, the wire connection port of the bottom cover is arranged transversely, because the lower part of the bottom cover is next to the workbench, and the wire connection port is difficult to lead if facing downwards.

, the terminal of the electromagnet sucker is connected with a switch through an electric wire, and the other end of the switch is connected with a lithium battery through an electric wire, because the mobile phone shell is small workpieces, the size of the working table is large, more vacant space for placing the switch and the lithium battery is available on the working table during processing, an external power supply is not needed, and the shield of the CNC can not be closed.

, the electromagnet is a 24V DC electromagnet, which is more safe than AC.

, the switch is a push button switch.

, the lithium battery is coated with a pressure sensitive adhesive layer on its outer surface, which prevents the lithium battery from moving in vibration because the worktable inevitably generates vibration.

The utility model has the advantages that: the reference column through the cell-phone shell inserts the boss and carries out the fixed of horizontal direction, then prevents through the suction that the electro-magnet sucking disc produced that the cell-phone shell from taking place to beat when milling the sky wire casing, and the inner chamber setting of boss cooperation cell-phone shell, can produce sufficient support to the cell-phone shell. In view of the utility model discloses an electro-magnet attracts the cell-phone shell, so only can be used for similar to the sculpture that adopts stainless steel or other ironwork cell-phone shells such as apple 4S.

In the figure, 1, a base; 2. a boss; 3. a through hole; 4. an electromagnet chuck; 5. a bottom cover; 6. a wiring port; 7. a switch; 8. a lithium battery; 9. and (5) mounting the lug.

Detailed Description

The following describes the embodiments of the present invention in steps with reference to the drawings:

as shown in fig. 1, 2, kinds of CNC engraving device, it includes the CNC machining center and installs the fixed establishment on the CNC machining center workstation, fixed establishment includes base 1, boss 2 and electromagnet chuck 4, base 1 is rectangle stainless steel block, the welding of base 1 top surface has boss 2, through-hole 3 (using three through-hole to signal as the example in the drawing) has been seted up to the reference column that boss 2 cooperation was waited to process the cell-phone shell inner chamber, rectangle recess has been seted up to base 1 bottom surface, just be located rectangle recess top and seted up a plurality of cylindrical recesses in the base 1, cylindrical recess corresponds the setting with through-hole 3 and communicates with the through-hole, electromagnet chuck 4 is inserted in the cylindrical recess, bottom 5 is gone into to the rectangle recess card for fix electromagnet chuck 4, wiring mouth 6 has been seted up to the wiring end that bottom 5 corresponds every electromagnet chuck 4, the welding of base 1 both sides has installation ear 9, installation ear 9 passes through the workstation rigid coupling of bolt and CNC machining center.

And the bottom cover 5 and the base are bonded by strong glue.

And the wiring port 6 of the bottom cover 5 is transversely arranged.

The wiring end of the electromagnet sucker 4 is connected with a switch 7 through an electric wire, and the other end of the switch 7 is connected with a lithium battery 8 through an electric wire.

The electromagnet suction cup 4 is a 24-volt direct current electromagnet.

The switch 7 is a push-button switch.

The outer surface of the lithium battery 8 is coated with a pressure sensitive adhesive layer.

In the embodiment, the lithium battery is a 24V lithium battery manufactured by Daggy electronics Inc. of Dongguan, is square in appearance and is convenient to place. The switch adopts Schneider XB7 series button switches. The electromagnet sucker is an H5231 electromagnet sucker manufactured by Landa electromagnet Co., Ltd, Shanshan city, the rated voltage of the electromagnet sucker is 24 volts, the power of the electromagnet sucker is 5 watts, and the sucker can generate 400-Newton suction.

In this embodiment, three electro-magnet suction cups are used to generate a suction force of 1200 newton, which of course cannot be applied to the handset housing in its entirety, but is sufficient to prevent it from jumping which would affect the milling of the grooves, because the handset housing is very small.

The foregoing embodiments and description have been provided to illustrate the principles and preferred embodiments of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
