Description

Technical Field

[0001] This utility model relates to the field of pen manufacturing technology, and in particular to a spring clamp for pen manufacturing. Background Technology

[0002] In pen manufacturing, the clamping spring is the core elastic component of the pen. Its machining accuracy directly determines the pen's clamping stability and user experience. The clamping spring is usually a thin sheet of metal, and its surface must be smooth and free of scratches. Therefore, it is necessary to use a clamp to hold and fix it during the manufacturing process.

[0003] Existing clamping springs have rubber pads at their contact points to prevent scratches on the spring surface, and an elastic buffer component is integrated into the clamping structure to buffer the clamping force and prevent plastic deformation of the spring due to rigid clamping. However, during long-term use, the rubber pads are prone to wear or hardening due to friction and aging, and the elastic buffer component will also lose elasticity due to repeated stress. Both need to be replaced regularly to maintain the clamping accuracy of the fixture. Existing technology is not convenient for disassembling and replacing the clamping spring fixture components, which does not meet people's usage needs. Utility Model Content

[0018] Please see Figures 1-4A rubber pad 10 is fixedly installed on one side of the clamping plate 9, away from the connecting plate 8. A buffer spring 11 is fixedly installed on the inner end of the mounting sleeve 6. A limit plate 12 is fixedly installed on one side of the buffer spring 11, and the limit plate 12 is fixedly connected to the connecting rod 7. A positioning groove 13 is opened on the inner end of the connecting plate 8. A positioning block 14 is fixedly installed on one side of the clamping plate 9, away from the rubber pad 10. The positioning block 14 is adapted to the positioning groove 13 and is located at the inner end of the positioning groove 13. The positioning block 14 is movably connected to the positioning groove 13. Fixing blocks 15 are fixedly installed on both sides of the clamping plate 9. The fixing blocks 15 are movably connected to the connecting plate 8. A bolt 16 is movably installed on one side of the fixing block 15. The bolt 16 passes through the fixing block 15 and extends to the inner end of the connecting plate 8. The bolt 16 is threadedly connected to the connecting plate 8. A positioning plate 17 is fixedly installed on one side of the 5th assembly, away from the mounting sleeve 6. The positioning plate 17 is movably connected to the connecting frame 4. Bolts 18 are movably installed at the four corners of one side of the positioning plate 17. Bolts 18 penetrate the positioning plate 17 and extend to the inner end of the connecting frame 4. Bolts 18 are threadedly connected to the connecting frame 4. A geared motor 19 is fixedly installed on one side of the processing table 1. The output shaft end of the geared motor 19 extends into the interior of the mounting groove 2. A double-acting screw 20 is fixedly installed at the output shaft end of the geared motor 19.

It can move simultaneously towards the center through the nut seat 3, connecting frame 4, and clamping plate 9, so that the clamping plate 9 clamps and fixes the spring. The buffer spring 11 in the mounting sleeve 6, under the action of the connecting rod 7 and connecting plate 8, can avoid the problem of excessive clamping force causing plastic deformation of the spring. The rubber pad 10 can prevent the surface of the spring from being clamped. To address the issue of scratches on clamping plate 9 and improve friction with the clamping spring, preventing loosening during processing, some components can be replaced after prolonged use, such as clamping plate 9, rubber pad 10, and mounting sleeve 6. Clamping plate 9 is connected to connecting plate 8 via fixing block 15 and bolt 16. Mounting sleeve 6 is connected to connecting frame 4 via positioning plate 17 and bolt 18. Bolt 16 and bolt 18 can be removed for replacement. After prolonged use, a fan can be used to clean the dust on the surface of bidirectional lead screw 20, and the dust is discharged through through groove 21.
