[0012] Preferably, the vacuum adsorption groove comprises an outer peripheral groove arranged circumferentially along the edge of the adsorption surface 2, a transverse groove arranged inside the outer peripheral groove and having two ends communicated with the outer peripheral groove respectively, and a longitudinal groove arranged inside the outer peripheral groove and having two ends communicated with the outer peripheral groove respectively, and the intersection point of the longitudinal groove and the transverse groove is located at the central part of the adsorption surface 2 and forms a vacuum port at the intersection groove.

[0013] In the present application, by setting the pressure relief groove outside the avoidance hole, the negative pressure difference between the vacuum suction groove and the avoidance hole is offset by the pressure relief groove, the negative pressure around the avoidance hole is blocked, so that the sundries are not easily adsorbed on the surface of the jig, and the cleanliness of the surface of the jig is ensured.

[0017] REFERENCE Figures 1-2 A mobile phone cover plate CNC machining jig is provided for the present application, which comprises: a jig body 1, the jig body 1 has an adsorption surface 2 matched with the workpiece to be machined for the workpiece to be machined, wherein:

[0018] The adsorption surface 2 is provided with a vacuum suction groove 3 for vacuum suction and an avoidance hole 4 for avoidance of the hole machining equipment. The adsorption surface 2 and the outside of the avoidance hole 4 are provided with a pressure relief groove 5, which comprises a ring groove 51 around the avoidance hole 4 and an exhaust groove 52 communicating with the ring groove 51 at one end and penetrating the side wall of the jig body 1 at the other end. The specific use of the jig is as follows:

[0019] REFERENCE Figure 3 The mobile phone cover plate to be machined is placed on the adsorption surface 2 of the jig and fixed by the vacuum adsorption force generated by the vacuum adsorption groove 3, and the pre-machining hole of the mobile phone cover plate is located at the position of the avoidance hole 4; then the mobile phone cover plate is placed in the hole machining equipment to complete the machining of the hole of the mobile phone cover plate by the hole machining equipment. Because the pressure relief groove 5 is provided outside the avoidance hole 4, the negative pressure around the avoidance hole 4 is blocked by the existence of the pressure relief groove 5, so that the glass waste or sundries in the environment or cutting liquid generated during the machining of the hole will not be adsorbed on the surface of the jig due to the vacuum adsorption force, thereby ensuring the cleanliness of the surface of the jig. The time for manual cleaning of the jig is saved.

[0020] In addition, when the number of avoidance holes 4 is more than two, each avoidance hole 4 has a ring groove 51 around it, and each ring groove 51 is in communication with each other and is in communication with the outside through the exhaust groove 52.

[0021] In this embodiment, the avoiding hole 4 is a through hole, so that sundries cannot stay inside.

[0022] In this embodiment, the plane where the groove bottom of the ring groove 51 is located is an inclined plane; the groove bottom of the exhaust groove 52 is inclined along its extension direction, and the highest end of the groove bottom of the exhaust groove 52 is connected with the lowest end of the groove bottom of the ring groove 51. The design of this structure makes the pressure relief groove 5 have good emptying performance, especially for liquid, so that when the cutting fluid or other sundries accidentally enters, it can be smoothly discharged to avoid blockage.

[0023] In this embodiment, the groove width of the pressure relief groove 5 is 2mm, and the groove depth is 2mm.

[0024] In this embodiment, the vacuum adsorption groove 3 includes an outer circumferential groove 31 arranged circumferentially along the edge of the adsorption surface 2, a transverse groove 32 arranged transversely inside the outer circumferential groove 31 and having both ends communicated with the outer circumferential groove 31 respectively, and a longitudinal groove 33 arranged longitudinally inside the outer circumferential groove 31 and having both ends communicated with the outer circumferential groove 31 respectively, and the intersection point of the longitudinal groove 33 and the transverse groove 32 is located at the central part of the adsorption surface 2 and forms a vacuum port 34 at the intersection groove. The design of this structure can guarantee the stability of adsorbing the mobile phone cover plate and ensure the uniformity of the adsorption force suffered by the mobile phone cover plate.

[0025] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this.
