Description

Technical Field

[0001] This utility model specifically relates to a CNC four-axis machining fixture for mobile phone accessories, belonging to the field of machining fixture technology. Background Technology

[0002] A jig is a tooling device used to assist in positioning or controlling the position and machining actions of a workpiece. By using jigs, production efficiency can be effectively improved, the repeatability of machining actions can be guaranteed, and machining accuracy can be increased, making it particularly suitable for mass production scenarios. Because different products have different structures and machining requirements, it is usually necessary to design and manufacture corresponding CNC jigs specifically for each product.

[0003] Currently, many cast parts (such as conductive blocks for mobile phones) require not only milling or finishing of the two sides in subsequent processing, but also drilling of the top. If a traditional bench vise is used for clamping, it often requires multiple disassembly and repositioning, resulting in long clamping time, large positioning errors, and seriously affecting processing efficiency and product consistency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a CNC four-axis machining fixture for mobile phone accessories, thereby achieving the above-mentioned objective.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CNC four-axis machining fixture for mobile phone accessories, comprising: A four-axis connector, with a clamping plate that can slide relative to it. A base is disposed between the two clamping plates, so that the two clamping plates hold the base, and at least one workpiece placement slot is formed inside the base; A cover plate, positioned directly above the base, is used to press the workpiece. At least one clamping box is disposed inside the cover plate and corresponds to the workpiece placement slot; At least one clamping element is disposed within the clamping box; A pressure plate is located directly below the clamping box and is connected to the clamping component; The driving component is connected to the cover plate in a transmission manner, so that the driving component drives the cover plate to drive the pressure plate to press the workpiece.

[0006] Furthermore, a first electric push rod is fixedly connected to the outer side of the clamping plate, and the first electric push rod is fixedly connected to the four-axis connecting seat.

[0007] Furthermore, the driving component includes a connecting plate, a first bolt, and a second electric push rod. The connecting plate is fixedly connected to the cover plate by the first bolt, and both ends of the connecting plate are respectively connected to the telescopic ends of the two second electric push rods.

[0008] Furthermore, the clamping component includes a slide rod, a push plate, and a spring. The surface of the slide rod is slidably connected to the clamping box, and the surface of the slide rod is fixedly connected to the push plate. The spring is sleeved on the outside of the slide rod, and the bottom of the spring is fixedly connected to the top of the push plate. The top of the spring is fixedly connected to the inner wall of the clamping box.

[0009] Furthermore, the inner wall of the base is provided with a first positioning hole, the inside of the cover plate is provided with a second positioning hole, and the top of the four-axis connecting seat is fixedly connected with several positioning rods. The positioning rods pass through the inside of the first positioning hole and the second positioning hole in sequence, so that the positioning rods can play a good positioning role.

[0010] Beneficial effects: This application matches the base's structural specifications and the position of its first positioning hole with the corresponding threaded hole on the four-axis connector. A bolt is then passed through the matching threaded hole on the four-axis connector and tightened to the connecting end of the positioning rod, thus securing the positioning rod firmly to the four-axis connector. Subsequently, the first positioning hole on the base is aligned with the installed positioning rod, allowing the positioning rod to smoothly insert into the first positioning hole, completing the precise positioning and assembly of the base on the four-axis connector.

[0011] This application, by activating the first electric push rod, pushes the two clamping plates on both sides to move towards each other, thereby clamping the mounting plates on both sides of the base, thus achieving stable fixation of the base during the processing and preventing displacement caused by cutting force or vibration.

[0012] In this application, the workpiece to be processed is accurately placed in the workpiece positioning groove at the top of the base. The second electric push rod is then activated, pulling the connecting plate to move the cover plate vertically downwards along the guide direction of the positioning rod. During the downward movement of the cover plate, the pressure plate inside the clamping box presses down synchronously, acting on the workpiece surface. Simultaneously, the pressure plate pushes the slide rod upwards, causing the push plate to compress the spring above. The compressed spring generates a uniform counter-force, which is transmitted to the pressure plate through the push plate and slide rod, forming a continuous and stable clamping force to ensure the workpiece is firmly clamped.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 As shown, a CNC four-axis machining fixture for mobile phone accessories includes a four-axis connecting seat 1. Both ends of the top of the four-axis connecting seat 1 are fixedly connected to a first electric push rod 6. Each first electric push rod 6 has a clamping plate 5 fixedly connected to its telescopic end. The two clamping plates 5 clamp the mounting plate of the base 2 to fix the base 2. The top of the four-axis connector 1 is provided with a positioning rod 4, and the positioning rod 4 is fixedly connected to the four-axis connector 1 by bolts. The top of the four-axis connector 1 is provided with threaded holes that match the bolts, and the threaded holes are arranged at equal intervals on the four-axis connector 1. The base 2 is provided with a first positioning hole 3 inside, and the positioning rod 4 passes through the inside of the first positioning hole 3 to provide a good positioning effect for the base 2. The base 2 is provided with a number of workpiece placement slots 21 for placing workpieces inside. The top of the base 2 is provided with a cover plate 7, which is used to press the workpiece. The cover plate 7 has a second positioning hole 8 inside, and the positioning rod 4 passes through the first positioning hole 3 and the second positioning hole 8 in sequence, so as to achieve a good positioning effect. The cover plate 7 has a pressure box 9 fixedly installed inside, which is located directly above the workpiece placement groove 21. The pressure box 9 has several elastic elements arranged at equal intervals inside. The elastic elements are composed of a slide rod 10, a push plate 11, and a spring 12. The slide rod 10 is slidably connected to the pressure box 9, and the surface of the slide rod 10 is fixedly connected to the push plate 11. The push plate 11 is slidably connected inside the pressure box 9. A spring 12 is provided between the top of the push plate 11 and the inner wall of the pressure box 9. The spring 12 is sleeved on the slide rod 10. One end of the spring 12 passes through the pressure box 9 and is fixedly connected to a pressure plate 13. The size of the pressure plate 13 matches the size of the workpiece placement groove 21, so that the pressure plate 13 compresses the workpiece. Both sides of the cover plate 7 are fixedly connected to the connecting plate 14 by the first bolt 15. The two ends of the connecting plate 14 are fixedly connected to the telescopic ends of the second electric push rod 16. The second electric push rod 16 is fixedly connected to the four-axis connecting seat 1 by bolts.

[0017] The implementation principle of a CNC four-axis machining fixture for mobile phone accessories in this application embodiment is as follows: Based on the structural specifications of the base 2 and the position of its first positioning hole 3, it is matched with the corresponding threaded hole position on the four-axis connecting seat 1. A bolt is passed through the matching threaded hole on the four-axis connecting seat 1 and tightened to the connecting end of the positioning rod 4, thus achieving a secure fixation between the positioning rod 4 and the four-axis connecting seat 1. Subsequently, the first positioning hole 3 on the base is aligned with the installed positioning rod 4, allowing the positioning rod 4 to smoothly insert into the first positioning hole 3, completing the precise positioning and assembly of the base on the four-axis connecting seat.

[0018] Next, the first electric push rod 6 is activated, which pushes the two clamping plates 5 to move towards each other, so that they clamp the mounting plates on both sides of the base 2, thereby achieving stable fixation of the base during the processing and preventing displacement caused by cutting force or vibration.

[0019] After the base is clamped, the workpiece to be processed is accurately placed in the workpiece positioning groove 21 on the top of the base 1. Then, the second electric push rod 16 is activated, which pulls the connecting plate 14 to drive the cover plate 7 to move vertically downward along the guide direction of the positioning rod 4. During the downward movement of the cover plate 7, the pressure plate 13 in the pressure box 9 is driven to press down synchronously, acting on the surface of the workpiece.

[0020] While the pressure plate 13 applies pressure, it pushes the slide bar 10 upward, causing the push plate 11 to compress the spring 12 above. After being compressed by 12, the spring generates a uniform reverse elastic force, which is transmitted to the pressure plate 13 through the push plate 11 and the slide bar 10, forming a continuous and stable clamping force to ensure that the workpiece is firmly clamped and effectively prevent loosening or displacement during processing.

[0021] This fixture structure enables rapid workpiece clamping, ensures reliability and adaptability, and offers advantages such as high positioning accuracy, convenient operation, and stable clamping.
