Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp for processing side holes of a mobile phone shell. Background Art

[0002] As an important component of mobile phones, mobile phone casings have diverse designs. Different mobile phone brands and models often have different casing designs, including casing materials, structures, colors, etc. Some mobile phone casings adopt an integrated casing design, that is, the side casing and the back casing are connected as one. This design usually has better structural strength and aesthetics because the entire casing can withstand external forces and protect internal components as a whole. At the same time, the integrated casing design also simplifies the production process and assembly process, improving production efficiency. Some mobile phone casings adopt a split casing design, that is, the side casing and the back casing are separate. This design can improve maintainability and meet the personalized needs of different users.

[0003] In the process of producing mobile phone shells, a special fixture is needed to fix the raw materials of the mobile phone shells. It can effectively fix the mobile phone shells to ensure stability and precision during side hole processing and surface treatment. This fixture that can clamp the side holes of the mobile phone during processing can be called a fixture for side hole processing of mobile phone shells.

[0004] However, when using this clamp to fix the side shell of the split mobile phone shell, two clamping plates are directly used to fix it. Since the side shell of the split mobile phone shell only includes the arc-shaped shell as the side of the mobile phone, its compressive strength is low. If the clamping force is high, the shell may be compressed to deformation, and if the clamping force is low, the shell may be pushed during the side hole processing, thereby causing errors in the side hole processing. The fixing difficulty is high. Before fixing the mobile phone shell, a lot of debugging is required to adjust the clamping force to an appropriate strength, and the adjustment operation is relatively cumbersome. Therefore, it does not meet the existing needs. In this regard, we propose a clamp for processing the side holes of mobile phone shells. Utility Model Content

[0005] The purpose of the utility model is to provide a clamp for processing side holes of a mobile phone case, so as to solve the problem proposed in the above-mentioned background technology that when using this clamp to fix the side shell of a split mobile phone case, two clamping plates are directly used to fix it. Since the side shell of this split mobile phone case only includes an arc-shaped shell as the side of the mobile phone, its compressive strength is low. If the clamping force is high, the shell may be compressed to deformation. If the clamping force is low, the shell may be pushed during the side hole processing, thereby causing errors in the side hole processing. The fixing difficulty is high. Before fixing the mobile phone case, a lot of debugging is required to adjust the clamping force to an appropriate strength, and the adjustment operation is relatively cumbersome.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixture for processing side holes of a mobile phone shell, comprising a fixture frame, a mobile phone side shell is provided on one side inside the fixture frame, an inner clamping mechanism is provided on the inner side of the mobile phone side shell, the inner clamping mechanism comprises a fixed head, four strip grooves, eight fixed cylinders, eight fixed rods and four synchronous moving mechanisms, the four strip grooves are respectively located at the four end corners of the outer surface of the fixed head, the eight fixed cylinders are respectively located on both sides of the four strip grooves, the fixed rods are fixed on the piston rods of the fixed cylinders, and the position of the fixed rods corresponds to the position of the inner wall of the mobile phone side shell, and the moving mechanism can drive the two fixed cylinders located in the same strip groove to move synchronously outward or inward.

[0007] Preferably, the inner clamping mechanism further comprises a horizontal bar cylinder, the piston rod of the horizontal bar cylinder is connected to an electric rotating head, and the electric rotating head is installed at a middle position of the upper end surface of the fixed head.

[0008] Preferably, the moving mechanism includes a stepper motor, the output shaft of the stepper motor is connected to a transmission shaft through a coupling, the outer surface of the transmission shaft is fixed with a bevel gear A, and both sides of the outer surface of the bevel gear A are meshed with a bevel gear B.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model comprises two fixing cylinders connected to fixing rods in the four strip-shaped grooves on the outer surface of the fixing head. When the side shell of the mobile phone needs to be fixed, the fixing rods are pushed outward by the fixing cylinders until the metal balls installed on the outer surface of the fixing rods contact the inner wall of the side shell of the mobile phone. Since the metal balls are spherical as a whole, as the fixing rods move, the fixing rods will move to the middle position of the curved inner wall of the side shell of the mobile phone, thereby preventing the side shell of the mobile phone from falling off. The eight fixing rods that are in indirect contact with the four inner walls of the side shell of the mobile phone respectively form eight support points, thereby directly fixing the side shell of the mobile phone. The above technical solution can more conveniently fix the side shell of the split mobile phone shell.

[0015] 2. The present invention can change the position of the metal ball in contact with the inner wall of the mobile phone side shell by a moving mechanism, thereby preventing the drilling tool from coming into contact with the metal ball when drilling at the position in contact with the metal ball on the outer surface of the mobile phone side shell, thereby preventing damage to the metal ball.
