Description

Technical Field

[0001] This utility model relates to the field of mobile phone mid-frame processing technology, and in particular to a mobile phone mid-frame gap shaping fixture. Background Technology

[0002] With the increasing demand for lightweight mobile phones, the amount of alloy used in product structural design has also decreased. This has led to weakened local structures. During CNC machining, the side button slot, due to the relatively weak structural design, experienced localized expansion, resulting in excessive gaps between the mid-frame and battery cover. The current solution to this product anomaly caused by the new structural design is to manually press and reshape the gaps in the mid-frame. While manual pressing can reshape some areas, it is inefficient, labor-intensive, unsuitable for mass production, and lacks stability. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model designs a mobile phone mid-frame gap shaping fixture.

[0004] The present invention adopts the following technical solution: A mobile phone mid-frame gap shaping fixture includes a fixed base plate, a fixed seat, a mobile phone mid-frame positioning platform, a shaping head, a cylinder, and a cylinder gripper. The fixed base plate is used to connect and fix to an external pressing machine. The shaping head is used to connect above the external pressing machine for shaping the outer expansion surface of the mobile phone mid-frame product. A fixed seat is fixedly installed on the fixed base plate. The mobile phone mid-frame positioning platform and the cylinder are fixedly installed on the side of the fixed seat. A mobile phone mid-frame positioning position is set on the mobile phone mid-frame positioning platform. The shaping head is correspondingly set above the mobile phone mid-frame positioning position. A cylinder gripper is fixedly installed on the output end of the cylinder. The cylinder gripper correspondingly clamps the mobile phone mid-frame product on the mobile phone mid-frame positioning position.

[0005] Preferably, a side support plate is provided on the fixed base below the positioning platform of the mobile phone mid-frame for use with mobile phone mid-frame products.

[0006] Preferably, the positioning position of the mobile phone frame is provided with a positioning post, which corresponds to the positioning hole on the mobile phone frame product.

[0007] As a preferred option, a gap support fixture is also included, which is placed inside the mobile phone frame product before shaping to prevent excessive pressure during shaping from causing the product to be scrapped.

[0008] Preferably, the fixed seat and the cylinder gripper are connected by a pin for circumferential limiting.

[0009] Preferably, the shaping head is made of urethane rubber, which can prevent damage to the product from three areas.

[0010] Preferably, the fixed base plate is provided with an installation step surface to facilitate the positioning of the fixing seat when it is installed on the fixed base plate.

[0011] Preferably, the fixed base plate is provided with an oblong mounting hole. This facilitates the adjustment of the mounting position of the fixed base plate on an external pressing machine.

[0012] The beneficial effects of this utility model are as follows: This utility model designs a fixture for shaping the gap in the middle frame of a mobile phone. The fixture achieves precise positioning and, in conjunction with a pressing machine, a fixed stroke and pressing amount, ensuring the stability and consistency of the product's shaping process. This effectively avoids the problems of incomplete shaping or paint cracking caused by inconsistent manual pressing force. Furthermore, using machine pressing instead of manual pressing avoids human fatigue and provides excellent protection for the operators. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model; In the diagram: 1. Fixed base plate, 2. Fixed seat, 3. Mobile phone mid-frame positioning platform, 4. Side support plate, 5. Shaping pressure head, 6. Gap support gauge, 7. Cylinder, 8. Cylinder pressure claw, 9. Positioning column. Detailed Implementation

[0014] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example: Figure 1 As shown, a mobile phone mid-frame gap shaping fixture includes a fixed base plate 1, a fixed seat 2, a mobile phone mid-frame positioning platform 3, a shaping pressure head 5, a cylinder 7, and a cylinder clamping claw 8. The fixed base plate is used to connect and fix to an external pressing machine. The shaping pressure head is used to connect above the external pressing machine for shaping the outer expansion surface of the mobile phone mid-frame product. A fixed seat is fixedly installed on the fixed base plate. The mobile phone mid-frame positioning platform and the cylinder are fixedly installed on the side of the fixed seat. A mobile phone mid-frame positioning placement position is set on the mobile phone mid-frame positioning platform. The shaping pressure head is correspondingly set above the mobile phone mid-frame positioning placement position. A cylinder clamping claw is fixedly installed on the output end of the cylinder. The cylinder clamping claw correspondingly clamps the mobile phone mid-frame product on the mobile phone mid-frame positioning placement position.

[0015] A side support plate 4 is provided on the mounting base below the positioning platform corresponding to the mobile phone mid-frame, for use with the mobile phone mid-frame product. A positioning post 9 is provided on the positioning placement position of the mobile phone mid-frame, and the positioning post is set with positioning holes on the mobile phone mid-frame product.

[0016] Furthermore, it also includes a gap support gauge 6, which is placed inside the mobile phone frame product before shaping to prevent excessive pressure during shaping from causing the product to be scrapped.

[0017] The fixed base and cylinder gripper are connected by a pin for circumferential limiting. The shaping pressure head uses urethane rubber, which avoids damage to the product in three ways.

[0018] The base plate has a stepped mounting surface to facilitate positioning of the mounting bracket when it is installed on the base plate. The base plate also has oblong mounting holes to facilitate adjustment of the base plate's position on an external pressing machine.

[0019] This invention designs a fixture for shaping the gap in a mobile phone frame. The fixture uses precise positioning and a pressing machine to fix the pressing amount, ensuring process stability and consistency during shaping. This effectively avoids the problems of incomplete shaping or paint cracking caused by inconsistent manual pressing force. Furthermore, using machine pressing instead of manual pressing avoids human fatigue and provides excellent protection for operators.

[0020] This invention utilizes a foot pedal to pneumatically control the pressure claws to press the product, ensuring stability during the product shaping process; the gap support fixture ensures that over-forming will not occur and deform the product during the shaping process; and the press machine controls the stroke to ensure consistent pressure.

[0021] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
