Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a multi-station processing device for an F-folded shell. Background Technology

[0002] As a key structural component in electronic devices, medical instruments, and industrial control terminals, the F-fold shell typically requires sequential drilling and bending processes. To improve efficiency, the industry generally adopts multi-station processing equipment, integrating different processes into the same device.

[0003] The existing multi-station switching mechanism of the F-fold shell device mostly adopts a linear translation structure. The fixture is moved along a straight line by a slide rail to switch stations. Although the positioning is relatively stable, it is necessary to wait for the return trip to change the workpiece. A long idle stroke is required, which leads to a decrease in processing efficiency. Utility Model Content

[0004] This invention provides a multi-station processing device for F-folded shells, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-station processing device for F-folded shells includes: The base has a support shaft rotatably mounted inside the shaft hole. The assembly is coaxially fixed on the support shaft. At least three support arms are provided at equal angles on the assembly. The support arms are provided with a clamping mechanism for pre-clamping the F-fold shell. The drive mechanism is mounted on the base and is connected to the support shaft for driving the adjustment of the support arm position on the assembly. The guide mechanism is installed between the base and the support arm. The guide mechanism is used to fix and clamp the F-folded shell at the processing station and to release the clamping mechanism in the disassembly and assembly area.

[0006] Furthermore, the clamping mechanism includes: A mounting base is installed at the end of the support arm, and the mounting base is provided with a positioning groove that is compatible with the F-folded rear shell; The drive shaft is slidably installed in the through hole of the fixed base. One end of the drive shaft is equipped with a clamping component, and the other end is connected to the guide mechanism. An adjusting component is installed on the external thread of the drive shaft. The spring is connected at both ends to the adjusting component and the support arm, and is fitted onto the outside of the drive shaft.

[0007] Furthermore, a traction ring is provided at the top of the drive shaft.

[0008] Furthermore, the guidance mechanism includes: The guide rail is mounted on the base and is coaxially mounted with the support shaft. The guide rail located on the disassembly / assembly area side is provided with a groove. The connecting pipe is threaded to the external thread of the drive shaft. A guide is rotatably mounted on the connecting pipe, and the guide is slidably connected to the guide rail. The locking element is installed in the threaded inner hole of the connecting pipe, and the end of the locking element abuts against the drive shaft.

[0009] Furthermore, multiple balls are arranged at equal angles on the connection surface between the guide member and the guide rail.

[0010] Furthermore, the drive mechanism includes: A servo motor is installed inside the base cavity, and a worm gear is coaxially mounted on the output end of the servo motor; The worm gear is coaxially mounted on the support shaft and meshes with the worm.

[0011] Furthermore, a single start of the servo motor causes the assembly on the support shaft to rotate one station through the meshing of the worm gear and worm wheel.

[0012] Furthermore, the worm gear is rotatably mounted on the auxiliary component, which is connected to the inner wall of the base.

[0013] The following technical effects can be achieved through the technical solution of this utility model: The base provides a rotating mounting foundation for the support shaft. The support shaft drives at least three support arms set at equal angles on the assembly to rotate, enabling continuous processing of the F-folded shell. When the rotation stops, it simultaneously corresponds to the bending area, drilling area, and disassembly area, achieving multi-station synchronous operation. The clamping mechanism on the support arm pre-clamps the F-folded shell. After clamping, the position is adjusted by the drive mechanism, allowing multi-process processing to be completed without repeated clamping, greatly saving clamping time. The guide mechanism fixes the clamping mechanism at the processing station and releases it at the disassembly area, ensuring the stability of the F-folded shell during processing and facilitating disassembly. Moreover, a single clamping can achieve multi-process processing, avoiding processing errors caused by repeated positioning and improving processing efficiency. Attached Figure Description

[0018] This application provides a multi-station processing device for F-folded shells, including: Base 1, with a support shaft 2 rotatably mounted inside the shaft hole; Assembly 3 is coaxially fixed on support shaft 2. At least three support arms 4 are provided at equal angles on assembly 3. The support arms 4 are provided with a clamping mechanism 5 for pre-clamping the F-fold shell. When the multiple support arms 4 stop rotating, three support arms 4 are simultaneously located in the bending area, drilling area and disassembly area. The drive mechanism 6 is mounted on the base 1 and is connected to the support shaft 2 for driving the support arm 4 on the assembly 3 to adjust its position. The guide mechanism 7 is installed between the base 1 and the support arm 4. The guide mechanism 7 is used to fix and clamp the F-fold shell to the clamping mechanism 5 at the processing station, and to release the clamping mechanism 5 in the disassembly and assembly area. Through the technical solution of this utility model, the base 1 provides a rotating mounting foundation for the support shaft 2. The support shaft 2 drives at least three support arms 4 set at equal angles on the assembly 3 to rotate, realizing continuous processing of the F-fold shell. When the rotation stops, it corresponds to the bending area, drilling area and disassembly area at the same time, realizing multi-station synchronous operation. The clamping mechanism 5 on the support arm 4 pre-clamps the F-fold shell. After clamping, the position is adjusted by the drive mechanism 6. Multi-process processing can be completed without repeated clamping, which greatly saves clamping time. The guide mechanism 7 fixes the clamping mechanism 5 at the processing station and releases it at the disassembly area, which not only ensures the stability of the F-fold shell during processing, but also facilitates disassembly and assembly. Moreover, multi-process processing can be realized in a single clamping to avoid processing errors caused by repeated positioning, while improving processing efficiency.

[0019] During use, the clamping mechanism 5 includes: The fixing seat 51 is installed at the end of the support arm 4. The fixing seat 51 is provided with a positioning groove that is adapted to the F-fold back cover. The fixing seat 51 can be replaced according to different models of F-fold back covers. The drive shaft 52 is slidably installed in the through hole of the fixed seat 51. One end of the drive shaft 52 is provided with a clamping member 53, and the other end is connected to the guide mechanism 7. An adjusting member 54 is installed at the external thread of the drive shaft 52. A guide post is provided at the sliding connection between the drive shaft 52 and the fixed seat 51 to restrict the relative rotation between the drive shaft 52 and the fixed seat 51. Spring 55 is connected at both ends to adjusting component 54 and support arm 4 respectively, and spring 55 is fitted on the outside of drive shaft 52; A traction ring 56 is provided at the top end of the drive shaft 52; Through the technical solution of this utility model, the positioning groove of the fixed seat 51 is adapted to the F-fold back shell to achieve precise pre-positioning. The drive shaft 52 restricts the relative rotation with the fixed seat 51 through the guide post, and drives the clamping member 53 to clamp the back shell to avoid displacement. The adjusting member 54 is threadedly engaged with the drive shaft 52 to adjust the pre-tightening force of the spring 55, adapting to different specifications of F-fold back shells and ensuring pre-clamping stability. One end of the drive shaft 52 is connected to the guide mechanism 7 to realize automatic clamping at the processing station and automatic loosening in the disassembly area. With the help of multi-station switching, there is no need to repeat clamping, which improves processing efficiency. The top traction ring 56 facilitates manual auxiliary operation and further ensures the convenience of clamping and disassembly.

[0020] As a preferred embodiment of the above, the guide mechanism 7 includes: The guide slide rail 71 is installed on the base 1. The guide slide rail 71 is coaxially installed with the support shaft 2. The guide slide rail 71 located on the disassembly and assembly side is provided with a groove. The connecting pipe 72 is threadedly connected to the drive shaft 52. The guide 73 is rotatably mounted on the connecting pipe 72, and the guide 73 is slidably connected to the guide rail 71. The locking element 74 is installed in the threaded inner hole of the connecting pipe 72, and the end of the locking element 74 abuts against the drive shaft 52; Multiple balls 75 are provided at equal angles on the connecting surface of the guide member 73 and the guide rail 71; Through the technical solution of this utility model, the guide rail 71 and the support shaft 2 are coaxially installed on the base 1, providing a sliding track for the guide 73. The slot on the disassembly area side allows the guide 73 to be unconstrained in this area, and cooperates with the guide mechanism 7 to realize the automatic release of the clamping mechanism 5. The connecting pipe 72 is threadedly engaged with the transmission shaft 52, and the end of the locking member 74 abuts against the transmission shaft 52 to lock the connection position of the two, so as to adapt to F-fold back shells of different thicknesses. The multiple balls 75 on the guide 73 are evenly distributed to reduce the sliding friction with the guide rail 71, making the workstation adjustment smoother and more efficient, and reducing component wear.

[0021] In the above embodiments, the drive mechanism 6 includes: A servo motor 61 is installed in the inner cavity of the base 1, and a worm gear 62 is coaxially mounted on the output end of the servo motor 61. Worm gear 63 is coaxially mounted on support shaft 2, and worm gear 63 is meshed with worm 62. The servo motor 61, when started in a single operation, drives the assembly 3 on the support shaft 2 to rotate one station by meshing the worm gear 62 and worm wheel 63. The worm gear 62 is rotatably mounted on the auxiliary component 64, and the auxiliary component 64 is connected to the inner cavity wall of the base 1; Through the technical solution of this utility model, the auxiliary component 64 is connected to the inner wall of the base 1 to provide a stable rotation support for the worm gear 62. The worm gear 62, which is coaxially mounted at the output end of the servo motor 61, meshes with the worm wheel 63 on the support shaft 2. The transmission accuracy is high and it has self-locking properties, which prevents the assembly 3 from rotating accidentally and ensures the stability of the workstation locking. When the servo motor 61 starts once, it drives the assembly 3 on the support shaft 2 to rotate one workstation through meshing transmission, so that the support arm 4 corresponds to the bending area, drilling area and disassembly area, thereby improving the efficiency of multi-workstation switching.
