Technical Field
[0001] The utility model relates to the technical field of mobile phone shell processing, in particular to a positioning fixture for leveling production of mobile phone shells. Background Art
[0002] Leveling is a process in the painting process, which refers to the process in which the paint gradually shrinks to the smallest area due to the effect of surface tension after it is applied but before it dries to form a film. The role of leveling is to flatten the paint droplets sprayed on the surface of the material after painting and to evaporate some of the solvent to prevent pinholes from appearing on the paint film during baking. Currently, in the processing of mobile phone cases, the mobile phone cases need to be painted, and in the spraying process, the mobile phone cases need to be leveled. When the mobile phone case is leveled, in order to prevent the mobile phone case from shifting during the process, a fixture is needed to fix the mobile phone case.
[0003] The utility model patent with authorization announcement number CN213108623U discloses a mobile phone case silk screen printing jig, which includes a carrier body, a limiting bottom plate, a cam connecting rod mechanism, a first clamping plate, a second clamping plate, a plurality of first springs and a plurality of second springs. The middle part of the carrier body is provided with a placement groove adapted to the mobile phone case; under the elastic action of the first spring and the second spring, the first clamping plate and the second clamping plate can firmly fix the mobile phone case to prevent the mobile phone case from shifting sideways during the rotation silk screen printing process, thereby improving the clamping stability of the mobile phone case.
[0004] Although the device can prevent the mobile phone case from shifting sideways during the rotary screen printing process by setting up the first clamping plate and the second clamping plate, the jig still has the following problems when used: when placing the mobile phone case, the jig needs to place the mobile phone case in a placement groove, and when the mobile phone case is leveled, the solvent volatile gas on the surface of the wet paint workpiece needs to be volatilized within a certain period of time, and the placement groove of the jig will affect the flow of air on the surface of the jig, which is not conducive to the volatilization of the wet paint gas on the surface of the mobile phone case, and will affect the leveling quality of the mobile phone case. In view of this, we propose a positioning jig for mobile phone case leveling production. Utility Model Content

[0030] In this embodiment, two opposite end faces of the two screw rods 14 are coaxially keyed to the secondary bevel gears 141, an adjusting screw 15 is installed above the two secondary bevel gears 141, the bottom end of the adjusting screw 15 is coaxially keyed to the main bevel gear 151, and the main bevel gear 151 is meshed with the secondary bevel gears 141 on both sides. This design facilitates the synchronous rotation of the screw rods 14 on both sides by rotating the adjusting screw 15, and has the advantages of easy use and quick operation.
[0031] In this embodiment, the adjusting screw 15 is made of plastic material, and an anti-slip groove is provided on the outer wall of the adjusting screw 15. This design facilitates the rotation of the adjusting screw 15 and improves the convenience of operation.
[0032] In this embodiment, the cross-section of the bracket 18 is L-shaped, and the bracket 18 is a plastic product. This design facilitates the installation of the first ejector pin 181 and the second ejector pin 182, and facilitates the fixing of the mobile phone case by the first ejector pin 181 and the second ejector pin 182.
[0033] In this embodiment, the first ejector pin 181 and the second ejector pin 182 are both cylindrical, and are made of rubber material.

The positioning pins 12 are inserted into the four corners of the bottom of the mobile phone case. Then the user rotates the adjusting screws 15 on both sides. The adjusting screws 15 drive the main bevel gear 151 to rotate. Since the main bevel gear 151 is meshed with the secondary bevel gears 141 on both sides, the secondary bevel gears 141 rotate and drive the screws 14 on both sides to rotate. As the screws 14 rotate, the sliders 16 on both sides move inward synchronously. The sliders 16 simultaneously drive the extension plate 17 and the bracket 18 to approach the mobile phone case. When the first ejector pin 181 is pressed against the side wall of the mobile phone case, the second ejector pin 182 moves to the top of the mobile phone case. At this time, the user stops rotating the adjusting screw 15, the mobile phone case is fixed, and the mobile phone case can be leveled.
