Description

Technical Field

[0001] This utility model relates to the field of vortex-cooled deep hole drill bit technology, and in particular to a vortex-cooled deep hole drill bit. Background Technology

[0002] Deep hole drills are cutting tools used for machining deep holes, typically for drilling relatively deep diameters. Compared to conventional drills, deep hole drills have a longer cutting body, allowing for efficient cutting within longer boreholes. They are widely used for machining precision components. Vortex-cooled deep hole drills are specifically designed for deep hole machining, incorporating vortex cooling technology to effectively improve machining efficiency and hole quality. Vortex cooling technology refers to the delivery of coolant through vortex channels inside or outside the drill bit, achieving improved cooling effect, enhanced cutting performance, and extended tool life.

[0003] However, existing vortex-cooled deep hole drills have low chip removal efficiency, causing chips to accumulate in the deep hole and hindering chip removal. This not only reduces machining stability and hole wall quality but also increases tool wear and reduces machining efficiency. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This utility model provides a vortex-cooled deep hole drill bit, which has the following beneficial effects:

[0018] 1. This vortex-cooled deep hole drill bit, through the setting of the vibration component, when the motor is started during use, the eccentric wheel rotates. The rotation of the eccentric wheel causes the moving arm to move up and down. The up and down movement of the moving arm causes the moving column to move up and down. The up and down movement of the moving column causes the moving column to hit the second disc, thereby generating a longitudinal vibration effect. The vibration can promote smoother chip discharge and reduce chip wear on the tool.

[0019] 2. This vortex-cooled deep hole drill bit, through the setting of the cooling component, injects coolant into the interior of the condenser tube during use, thereby reducing the temperature of the condenser tube. The reduced temperature of the condenser tube reduces the temperature of the water flow inside the water guide tube, and the water flow through the water guide tube to the water spray pipe, so that the water flow from the water spray pipe to the cutting edge, thereby achieving the effect of cooling the cutting edge. This can effectively improve tool life, machining accuracy, cutting stability and efficiency, and reduce tool deformation caused by excessive temperature. Attached Figure Description

[0026] Please see Figures 1 to 4 This utility model provides a technical solution: a vortex-cooled deep hole drill bit, comprising a drill body 1, a cooling assembly 2 fixedly connected inside the drill body 1, the cooling assembly 2 including a condenser pipe 201 fixedly connected inside the drill body 1, a water guide pipe 202 fixedly connected inside the drill body 1, four water spray pipes 203 fixedly connected to the top of the water guide pipe 202, a disc 3 fixedly connected to one side of the cooling assembly 2, a vibration assembly 4 fixedly connected to the top of the disc 3, the vibration assembly 4 including a motor 401 fixedly connected to the top of the disc 3, an eccentric wheel 402 fixedly connected to one side of the motor 401, and a moving arm 403 fixedly connected to one side of the eccentric wheel 402.

[0027] Four cutting edges 5 are fixedly connected to one side of the drill body 1. Water spray nozzles are opened at the top of the cutting edges 5. The cutting edges 5 are designed to cut materials.

[0028] A guide drill bit 6 is fixedly connected to the top of the drill body 1, and a drill shank 7 is fixedly connected to the bottom of the drill body 1. The guide drill bit 6 helps to keep the drill bit stable.

[0029] The bottom of the drill shank 7 is threaded with a cylinder 8. Both the inside of the cylinder 8 and the bottom of the drill shank 7 are threaded. The cylinder 8 facilitates disassembly.

[0030] A support plate 9 is fixedly connected to the top of the disc 1 3, and a disc 2 10 is fixedly connected to the top of the support plate 9. The support plate 9 serves to fix the disc 2 10.

[0031] The bottom of the drill shank 7 is fixedly connected to the mounting block 11, and the bottom of the mounting block 11 is provided with a water inlet. A filter screen 12 is fixedly connected inside the water inlet. The filter screen 12 is designed to prevent the water inlet pipe from being blocked.

[0032] A baffle 13 is fixedly installed on one side of the support plate 9. A movable column 14 is slidably connected inside the baffle 13. The movable column 14 serves to generate vibration by colliding with the disc 10.

[0033] In this invention, the working steps of the device are as follows:

[0034] First step: When in use, start the motor 401 to make the eccentric wheel 402 rotate. The rotation of the eccentric wheel 402 causes the moving arm 403 to move up and down. The up and down movement of the moving arm 403 causes the moving column 14 to move up and down. The up and down movement of the moving column 14 causes the moving column 14 to strike the disc 10, thereby producing a longitudinal vibration effect.

[0035] The second step: When in use, coolant is injected into the condenser tube 201, which lowers the temperature of the condenser tube 201. The lower temperature of the condenser tube 201 lowers the temperature of the water flow inside the water guide tube 202. The water flow inside the water guide tube 202 flows to the water spray tube 203, and the water flow from the water spray tube 203 flows to the blade 5, thereby achieving the effect of cooling the blade 5.
