Description

Technical Field

[0001] The utility model relates to the technical field of throat hoop processing, in particular to a cutting device for throat hoop processing. Background Art

[0002] The throat clamp is a mechanical fastener, which is mainly used for the connection and fixation of pipes or cylindrical objects. It consists of a ring structure with an opening and a fastening screw. By adjusting the screw, the diameter of the throat clamp can be reduced or increased, thereby achieving the fastening effect on pipes and other components. Due to its simple structure, the throat clamp is easy to install and disassemble, and can be quickly repaired or replaced without disconnecting the pipeline. Therefore, it is widely used in many industrial fields such as automobiles, fire protection and chemical industries. In addition, the throat clamp is also favored for its good sealing performance and ability to adapt to pipes of different sizes. During the processing process, the throat clamp needs to be cut. The one-size-fits-all method may leave some burrs, unevenness or tiny cracks around the cut surface. These defects may be caused by the cutting tool not being sharp enough, the cutting speed being too fast or the fragility of the material itself, so the throat clamp needs to be polished after cutting. For this reason, we propose a cutting device for throat clamp processing. Utility Model Content

[0026] A grinding assembly is installed on the top of the workbench 1 and is used to grind the cutting surface of the throat hoop 7.

[0027] The limiting assembly is installed on the side wall of the workbench 1 and is used for the stable rotation of the grinding assembly.

[0028] A motor 8 is fixedly arranged on the top of the workbench 1, and a driving gear 9 is fixedly connected to the output shaft of the motor 8. The output shaft of the motor 8 drives the driving gear 9 to rotate.

[0029] The grinding assembly includes a main rod 10, a driven gear 11, an adjusting spring 12 and a grinding disc 13. The main rod 10 is movably installed on the top of the workbench 1, and the driven gear 11 is fixedly connected to the top of the main rod 10. The adjusting spring 12 is sleeved on the outer wall of the main rod 10. The bottom end of the main rod 10 extends into the workbench 1 and is fixedly connected to a grinding disc 13 for grinding the cutting surface of the throat hoop 7 just above the corresponding throat hoop 7. When the cutting surface of the throat hoop 7 needs to be polished, the driven gear 11 is pressed to make the driven gear 11 push the main rod 10 to slide downward on the top of the workbench 1. When the cutting surface of the throat hoop 7 needs to be polished, the driven gear 11 is pressed to make the driven gear 11 push the main rod 10 to slide downward on the top of the workbench 1, and the adjusting spring 12 slides down through the driven gear 11 so that it is compressed and deformed by the driven gear 11.

[0030] An annular groove 14 is provided in the middle of the main rod 10 for stable rotation of the main rod 10. When the driven gear 11 slides downward to engage with the driving gear 9, the double limiting rod 15 is pulled upward to make the bottom end of the double limiting rod 15 disengage from the limiting hole 17 on the push plate 16, and then the push plate 16 is pushed to one side of the main rod 10 so that the arc plate 18 on the push plate 16 is inserted into the annular groove 14 to prevent the main rod 10 from returning to its original position due to the rebound force generated by the adjustment spring 12.

[0031] The driving gear 9 and the driven gear 11 are meshed with each other. At this time, the bottom end of the grinding disc 13 is completely fitted with the bottom end of the throat hoop 7. The driving gear 9 drives the main rod 10 to rotate, so that the bottom of the grinding disc 13 grinds the cutting surface of the throat hoop 7.

[0032] The limiting assembly includes a double limiting rod 15, a push plate 16, a limiting hole 17 and an arc plate 18. The back of the workbench 1 is slidably connected with the push plate 16. The end of the push plate 16 extends to the front of the workbench 1 and is fixedly connected with the arc plate 18. The top of the arc plate 18 is provided with a plurality of groups of limiting holes 17 arranged at equal distances. The top of the workbench 1 is slidably connected with the double limiting rod 15. The double limiting rod 15 is opened to slide downward until the bottom end of the double limiting rod 15 is inserted into the limiting hole 17 on the push plate 16 to prevent the main rod 10 from moving up and down during rotation.

[0033] The bottom end of the double limiting rod 15 extends out of the top inner wall of the workbench 1 and is movably inserted into the limiting hole 17. The arc plate 18 is movably clamped into the annular groove 14. After the arc plate 18 is inserted into the annular groove 14 on the main rod 10, the double limiting rod 15 is inserted into the limiting hole 17 on the push plate 16. Inserting the arc plate 18 into the annular groove 14 can prevent the main rod 10 from throwing the arc plate 18 out of the annular groove 14 when rotating. The cutting surface of the throat clamp 7 can be polished through the stable rotation of the main rod 10. Removing burrs and sharp edges can reduce the risk of injury to personnel during operation, especially in metal processing. Burrs can easily scratch fingers. The surface of the throat clamp after polishing will be smoother and brighter, which improves the aesthetics of the product and is conducive to improving customer satisfaction.

[0034] Working principle: When in use, first place the throat clamp 7 on the top of the workbench 6, then start the cylinder 3 so that the piston rod on the cylinder 3 pushes the double push rod 4 to slide toward the front of the workbench 1, and the cutting knife 5 cuts off the throat clamp 7 through the lateral movement of the double push rod 4. When it is necessary to grind the cutting surface of the throat clamp 7, press the driven gear 11 so that the driven gear 11 pushes the main rod 10 to slide downward on the top of the workbench 1, and the adjustment spring 12 slides down through the driven gear 11 so that it is compressed and deformed by the driven gear 11. When the driven gear 11 slides downward to mesh with the driving gear 9, pull the double limiting rod 15 upward to disengage the bottom end of the double limiting rod 15 The limit hole 17 on the push plate 16 is released, and the push plate 16 is pushed toward one side of the main rod 10 so that the arc plate 18 on the push plate 16 is inserted into the annular groove 14 to prevent the main rod 10 from returning to its original position due to the rebound force generated by the adjustment spring 12. At this time, the bottom end of the grinding disc 13 is completely in contact with the bottom end of the throat hoop 7, and the driving gear 9 is engaged with the driven gear 11 to drive the main rod 10 to rotate, so that the bottom of the grinding disc 13 grinds the cutting surface of the throat hoop 7, and the double limiting rod 15 is loosened to slide the double limiting rod 15 downward until the bottom end of the double limiting rod 15 is inserted into the limit hole 17 on the push plate 16 to prevent the main rod 10 from moving up and down during rotation.
