Description

Technical Field

[0001] The utility model relates to the technical field of machining fixtures, in particular to an integrated CNC fine milling fixture for a mobile phone middle frame. Background Art

[0002] Chinese utility model patent with patent number ZL201921575241.3 and patent name "Adsorption type CNC side milling tooling fixture" actually discloses a CNC fine milling fixture for a mobile phone middle frame; specifically, the adsorption type CNC side milling tooling fixture includes legs, a support plate, a machine body, a tooling fixture table, an adsorption plate, a fine milling head, a connecting element, fixing bolts, and a power device. Its characteristics are that the legs are placed at the bottommost of the whole machine, a support plate is arranged above the legs, a machine body is arranged above the support plate, a tooling fixture table is arranged in front of the machine body, an adsorption plate is arranged in the middle of the tooling fixture table, a fine milling head is arranged at the upper left corner of the adsorption plate, a connecting element is connected to the outside of the fine milling head, a plurality of fixing bolts are respectively arranged around the adsorption plate, and a power device is arranged behind the tooling fixture table and above the machine body.

[0003] When the above adsorption type CNC side milling tooling fixture works, the mobile phone middle frame is adsorbed and fixed by the adsorption plate. It should be noted that for this adsorption plate, crisscross negative pressure adsorption grooves are arranged in its adsorption area, and a sealing rubber ring in a fully enclosed shape is installed on the periphery of the adsorption area of the adsorption plate; when the adsorption plate adsorbs the mobile phone middle frame, the structural surface of the mobile phone middle frame is attached to the sealing rubber ring, and the negative pressure adsorption grooves generate negative pressure suction under the action of vacuum pumping to adsorb and fix the mobile phone middle frame.

[0004] It should be noted that for the above adsorption plate, it has the following defects. Specifically: since the sealing rubber ring on the adsorption plate will have problems such as wear or aging, this will cause the sealing rubber ring not to be able to stably fit the structural surface of the mobile phone middle frame when adsorbing and fixing the middle frame, that is, the sealing rubber ring is not completely attached to the structural surface of the mobile phone middle frame. Once this situation occurs, the mobile phone middle frame will fall off the adsorption plate, resulting in scratches or even scrapping of the surface of the mobile phone middle frame. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an integrated CNC fine milling fixture for a mobile phone middle frame aiming at the deficiencies of the prior art. The integrated CNC fine milling fixture for a mobile phone middle frame has a novel structural design, good stability and reliability, and can effectively avoid the problem of the mobile phone middle frame falling off.

[0006] To achieve the above purpose, the utility model is realized through the following technical solutions.

[0007] An integrated mobile phone middle frame CNC precision milling fixture includes an adsorption plate body, the front of the adsorption plate body is a contoured surface adapted to the structural surface of the mobile phone middle frame, a negative pressure adsorption area is arranged on the front of the adsorption plate body, and a negative pressure adsorption groove is opened on the front of the adsorption plate body at the position of the negative pressure adsorption area;

[0011] The front side of the adsorption plate body is provided with a rubber ring installation groove in a full-circle shape at the circumference of each negative pressure adsorption area, and a sealing rubber ring extending along the corresponding rubber ring installation groove is installed in each rubber ring installation groove.

[0012] Wherein, the negative pressure adsorption groove includes a transverse groove extending laterally and a longitudinal groove extending longitudinally, and the longitudinal groove is connected with the transverse groove in an alternating manner.

[0013] Among them, at least two countersunk holes are opened on the front side of the adsorption plate body beside the negative pressure adsorption area, and an auxiliary suction nozzle is installed in each countersunk hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects, specifically:

[0015] 1. When the mobile phone middle frame is fixed by adsorption, the negative pressure adsorption area and the auxiliary suction nozzle cooperate with each other and the negative pressure adsorption acts on the structural surface of the mobile phone middle frame at the same time, so the adsorption is stable and reliable;

[0016] 2. When the sealing rubber ring located on the side of the negative pressure adsorption area is worn or aged and cannot stably adsorb and fix the mobile phone middle frame in the negative pressure adsorption area, the utility model can still adsorb and fix the structural surface of the mobile phone middle frame through the auxiliary suction nozzle, which can effectively avoid the problem of the mobile phone middle frame falling off;

[0028] In the process of adsorbing and fixing the mobile phone middle frame by using the CNC fine milling fixture for the integrated mobile phone middle frame of the first embodiment, the mobile phone middle frame to be subjected to CNC fine milling is placed on the front surface of the adsorption plate main body 1. Since the front surface of the adsorption plate main body 1 is a profiling surface, that is, the structural surface of the mobile phone middle frame can fit well with the front surface of the adsorption plate main body 1. After the mobile phone middle frame is placed on the front surface of the adsorption plate main body 1, the negative pressure adsorption grooves 3 in the negative pressure adsorption area 2 and the auxiliary suction nozzles 7 in the counterbores 6 perform a vacuum pumping action and simultaneously negatively adsorb the structural surface of the mobile phone middle frame, thereby realizing the adsorption and fixation of the mobile phone middle frame.

[0029] It should be noted that for the CNC fine milling fixture for the integrated mobile phone middle frame of the first embodiment, when adsorbing and fixing the mobile phone middle frame, through the cooperation of the negative pressure adsorption area 2 and the auxiliary suction nozzles 7 and simultaneously negatively adsorbing the structural surface of the mobile phone middle frame, the adsorption stability and reliability are good.

[0030] In addition, when the sealing rubber ring 5 located on the peripheral side of the negative pressure adsorption area 2 is worn or aged and cannot stably adsorb and fix the mobile phone middle frame by the negative pressure adsorption area 2, the first embodiment can still adsorb and fix the structural surface of the mobile phone middle frame through the auxiliary suction nozzles 7, so as to effectively avoid the problem of the mobile phone middle frame falling off.

[0031] Based on the above situation, through the above structural design, the CNC fine milling fixture for the integrated mobile phone middle frame of the first embodiment has the advantages of novel structural design, good stability and reliability, and can effectively avoid the problem of the mobile phone middle frame falling off.

[0034] By providing a plurality of negative pressure adsorption areas 2, the CNC fine milling fixture for the integrated mobile phone middle frame of the second embodiment can further improve the stability of the adsorption and fixation of the mobile phone middle frame, and can still maintain the negative pressure adsorption effect by the other negative pressure adsorption areas 2 when the adsorption effect of one negative pressure adsorption area 2 fails, thereby also effectively avoiding the problem of the mobile phone middle frame falling off.

[0035] Embodiment 3, as Figure 1 and Figure 2As shown in the figure, the difference between the third embodiment and the first embodiment is that at least two counterbores 6 are formed on the front surface of the adsorption plate body 1 beside the negative pressure adsorption area 2, and auxiliary suction nozzles 7 are respectively installed in each counterbore 6.
