Detailed description of the invention

For the ease of the understanding of those skilled in the art, below in conjunction with embodiment and accompanying drawing, this utility model being further described, the content that embodiment is mentioned is not to restriction of the present utility model.

Refer to shown in Fig. 1 and Fig. 2, a kind of CNC of the present utility model processes inverse jig, including base plate 1, and base plate 1 interval arranges and is positioned at the top board 2 above base plate 1, the guide pillar 3 of connecting bottom board 1 and top board 2, top board 2 and base plate 1 are separately fixed at the top and bottom of guide pillar 3, being provided with groove 20 on top board 2, be slidably connected at the gripper shoe 4 on guide pillar 3, gripper shoe 4 is between base plate 1 and top board 2, being installed in the actuator 5 on base plate 1, the outfan of actuator 5 and gripper shoe 4 link together.

Time actually used, phone housing to be processed is placed in gripper shoe 4, actuator 5 drives gripper shoe 4 to move up along guide pillar 3, and then is clamped by phone housing and be fixed between gripper shoe 4 and top board 2, and Digit Control Machine Tool is processed on phone housing by the groove 20 on top board 2; This utility model CNC processes inverse jig simple in construction, easy to use, by coordinating Digit Control Machine Tool that phone housing is processed, it is possible to be greatly promoted working (machining) efficiency and the machining accuracy of phone housing.

Described base plate 1 is substantially in flat rectangle, and the two ends, left and right of base plate 1 are also respectively provided with breach 10, utilizes bolt etc. CNC can process inverse jig easily through breach 10 and is fixed on predetermined installation site. One end of guide pillar 3 is arranged on the upper surface of base plate 1, the cylinder of guide pillar 3 substantially strip, and the lower surface of top board 2 is arranged on the other end of guide pillar 3, and top board 2 is similarly flat rectangle. In the present embodiment, the two ends, left and right of base plate 1 are separately installed with two guide pillars 3, four approximately fixed corners at top board 2, base plate 1 of guide pillar 3, it is ensured that top board 2 and base plate 1 are firmly coupled to each other. Certainly, according to specific needs, those skilled in the art can also reduce or increase the quantity of guide pillar 3, such as, reduces the quantity of guide pillar 3 to one.

Being equiped with linear bearing 40 in described gripper shoe 4, linear bearing 40 is set on guide pillar 3. It is point cantact between bearing ball and guide pillar 3 in linear bearing 40, bearing ball rolls with minimum frictional resistance, it is little that linear bearing 40 has friction, and it is more stable, do not change with bearing speed, guarantee that gripper shoe 4 can obtain steady rectilinear motion highly sensitive, that precision is high along guide pillar 3, it is to avoid because the vibrations produced when gripper shoe 4 is moved are by phone housing crimp. Preferably, linear bearing 40 adopts plastic linear bearing 40, plastic linear bearing 40 to have self-lubricating property, and the slip film of plastic linear bearing 40 adopts selflubricatingpiston to make, and it is in use without additionally using lubricating oil to safeguard.

In the present embodiment, gripper shoe 4 is provided with perforation 42, one end of linear bearing 40 is provided with baffle plate 41, the other end of linear bearing 40 is encased in perforation 42 from the upper end of gripper shoe 4, utilize baffle plate 41 by linear bearing 40 block on the upper surface of gripper shoe 4, it is to avoid linear bearing 40 drops from perforation 42. Certainly, as required, linear bearing 40 also can be fixed on the outside of gripper shoe 4 by those skilled in the art, now without offering perforation 42 in gripper shoe 4.

Referring to shown in Fig. 1, Fig. 2 and Fig. 3, described gripper shoe 4 is also detachably connected with Die and mould plate 6, Die and mould plate 6 is installed in the upper surface of gripper shoe 4, and namely Die and mould plate 6 is between gripper shoe 4 and top board 2, and Die and mould plate 6 is provided with die cavity 60. Time actually used, phone housing to be processed is placed in die cavity 60, phone housing is clamped between Die and mould plate 6 and top board 2, it is to avoid phone housing deforms because of unbalance stress because being clamped directly between gripper shoe 4 and top board 2. Additionally, according to different phone housing shapes, those skilled in the art can change different Die and mould plates 6.

In the present embodiment, Die and mould plate 6, less than the area of gripper shoe 4, so can be installed in gripper shoe 4 by the area of described Die and mould plate 6 quickly and easily, and can also be prevented effectively from Die and mould plate 6 touches guide pillar 3 in installation process simultaneously, causes installation inconvenience.

Being additionally provided with two limited posts 61 being spaced on described Die and mould plate 6, each limited post 61 protrudes out to top board 2 from the upper surface of Die and mould plate 6 respectively and forms, and die cavity 60 is between two limited posts 61. Time actually used, the both sides of phone housing are respectively arranged with collar (not shown), are set in by the collar on limited post 61, it is possible to be positioned at by phone housing in Die and mould plate 6 easily, it is to avoid phone housing rocks back and forth on Die and mould plate 6.

Refer to shown in Fig. 1, Fig. 2 and Fig. 4, described top board 2 is additionally provided with the spacing hole 21 coordinated with limited post 61, after actuator 5 drives gripper shoe 4 and moves up to top board 2 together with Die and mould plate 6, limited post 61 is installed with in spacing hole 21 together with the collar of phone housing, and then is clamped in firm for phone housing between Die and mould plate 6 and top board 2.

Described gripper shoe 4 is provided with the first through hole 43, Die and mould plate 6 is provided with the second through hole 62 connected with the first through hole 43, time actually used, vacuum slot or other element producing negative pressure are installed in the first through hole 43 and/or the second through hole 62, after phone housing is placed in the die cavity 60 of Die and mould plate 6, phone housing is firmly adsorbed on Die and mould plate 6 by vacuum slot, it is to avoid phone housing drops from Die and mould plate 6. Preferably, the second through hole 62 is located substantially at the center of Die and mould plate 6, it is ensured that warpage will not occur whole phone housing because one end stress is excessive in Die and mould plate.

In the present embodiment, described actuator 5 is for driving cylinder, according to the distance size between gripper shoe 4 and top board 2, select the driving cylinder of different stroke, relative to utilizing drive motor or hydraulic motor as actuator 5, utilize the overall structure driving cylinder can simplify CNC processing inverse jig, further auxiliary to simplify CNC and process the structural design of inverse jig.

In the present embodiment, the quantity of described actuator 5 is two, two actuators 5 are connected to the opposite end of gripper shoe 4, guarantee, when gripper shoe 4 is slided along guide pillar 3, there is enough power on the one hand, also gripper shoe 4 two ends stress equalization is ensured on the other hand, prevent gripper shoe 4 two ends because being caused by force unbalance Digit Control Machine Tool that mismachining tolerance occurs on phone housing, in turn result in phone housing processing bad.

Known this utility model is have above-described good characteristic in sum, is made it on using, promotes the usefulness not having in conventional art and have practicality, become the product of a great practical value.

Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this specification content should not be construed as restriction of the present utility model.
