Description

Technical Field

[0001] This utility model relates to the field of deep hole cutting tool technology, and in particular to a deep hole cutting tool with an anti-vibration structure. Background Technology

[0002] Deep hole cutting tools are tools specifically designed for machining holes with a large length-to-diameter ratio. They are widely used in aerospace, automotive manufacturing, mold processing and other fields to machine deep holes in parts such as engine blocks, gun barrels and mold cavities. Different types of tools are specifically optimized according to the length-to-diameter ratio, material hardness and precision requirements of the machining scenario to ensure stable cutting in complex deep hole machining environments.

[0003] When traditional deep hole cutting tools are used for countersinking operations, a large amount of waste chips generated during the machining process tend to accumulate in the cutting area. If they are not cleaned in time, they will lock the cutting inserts, hindering the normal operation of the tool and further aggravating vibration and machining errors. The cutting inserts generate a lot of heat when cutting at high speeds, and existing cooling methods are often unable to cool the inserts accurately and efficiently, resulting in accelerated insert wear and shortened service life. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a deep hole cutting tool with an anti-vibration structure. Through multi-damping combined with vibration reduction, the error caused by vibration during workpiece processing is reduced. The centrifugal force generated by the rotation of the tool body drives the rotary bearing to rotate around the rotary axis, reducing jamming caused by vibration during processing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A deep-hole cutting tool with a vibration-resistant structure includes a tool body. A damping groove is provided on the inner side of the left end of the tool body. A first infusion hole passes through the inner side of the tool body. A first limiting block is movably connected to the right end of the inner side of the damping groove. A second infusion hole passes through the inner side of the first limiting block. A vibrating core is movably connected to the middle of the inner side of the damping groove. Rubber dampers are movably connected to the inner sides of both ends of the vibrating core. A second limiting block is movably connected to the left end of the inner side of the damping groove.

A rotating shaft is fixedly connected to the upper front end of the blade support. A rotating bearing is rotatably connected to the periphery of the rotating shaft. A cutting blade is fixedly connected to the upper side of the rotating bearing. A cutting edge is provided on the right end of the cutting blade. A support damping assembly is provided on the periphery of the right end of the tool body.

[0007] Furthermore, the support damping assembly includes a support seat located on the lower right side of the blade body, a screw cap installed on the upper end of the support seat, and multiple fixing bolts provided on both the screw cap and the front and rear sides of the support seat.

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.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a deep hole cutting tool with an anti-vibration structure, comprising a tool body 3, a damping groove 26 provided on the inner side of the left end of the tool body 3, a first infusion hole 4 passing through the inner side of the tool body 3, a first limiting block 5 movably connected to the right end of the inner side of the damping groove 26, a second infusion hole 6 passing through the inner side of the first limiting block 5, a vibrating core 7 movably connected to the middle of the inner side of the damping groove 26, rubber dampers 10 movably connected to the inner sides of both ends of the vibrating core 7, and a second limiting block 8 movably connected to the left end of the inner side of the damping groove 26. 3. A fixed circular plate 9 is fixedly connected to the left end of the blade body 3. A blade support 16 is movably connected to the left end of the fixed circular plate 9. A rotating shaft 19 is fixedly connected to the upper front end of the blade support 16. A rotating bearing 20 is rotatably connected to the outer periphery of the rotating shaft 19. A cutting blade 17 is fixedly connected to the upper side of the rotating bearing 20. A cutting edge 18 is provided at the right end of the cutting blade 17. A support seat 2 is provided at the lower right end of the blade body 3. A screw cover 1 is installed on the upper end of the support seat 2. Multiple fixing bolts 25 are provided on the front and rear sides of the screw cover 1 and the support seat 2.

[0026] When the workpiece needs to be undercut, the rubber damper 10 is installed around the damping support 12. The rubber damper 10 installed on the right end of the second limiting block 8 is installed on the left end of the vibrating core 7. The rubber damper 10 installed on the left end of the first limiting block 5 is installed on the right end of the vibrating core 7. During installation, the fourth liquid inlet 15 needs to be aligned with the center of the coolant pipe 11. The assembled vibrating core 7 is installed inside the damping groove 26 opened on the left end of the tool body 3, so that the center of the first liquid inlet 4 is aligned with the center of the second liquid inlet 6. The fixing disc 9 is fixedly connected to the left end of the tool body 3, so that the center of the third liquid inlet 13 is aligned with the center of the fifth liquid inlet 24. The center of the first positioning hole 14 corresponds one-to-one with the center of the second positioning hole 21. The tool is then... After the internal damping system of body 3 is installed, rotate the cutter body 3 clockwise from the left side. This allows the rotary bearing 20 to receive the centrifugal force generated by the rotation of the cutter body 3, causing the rotary bearing 20 to rotate around the rotary shaft 19 until the cutting insert 17 unfolds. The cutter body 3 then advances to the right, and the cutting edge 18 at the right end of the cutting insert 17 acts on the workpiece to process it. When the tool needs to be retracted after processing, rotate the cutter body 3 counterclockwise from the left side. This causes the cutting insert 17 to receive a centrifugal force in the opposite direction and retract it towards the inside of the insert support 16. The cutter body 3 continues to advance to the right, causing the insert support 16 to retract to the right, thus reducing jamming caused by vibration during processing.

[0027] Reference Figures 4-5 Damping supports 12 are installed on the inner sides of the rubber dampers 10 on both the left and right sides. A fourth infusion hole 15 is provided on the inner side of the damping support 12. The opposite sides of the damping support 12 are fixedly connected to the opposite sides of the first limiting block 5 and the second limiting block 8, respectively. Multiple first positioning holes 14 are provided on the rear right side of the second limiting block 8. A third infusion hole 13 is provided on the front end of the second limiting block 8. Multiple second positioning holes 21 are provided on the rear end of the fixed disc 9. A fifth infusion hole 24 is provided on the front end of the fixed disc 9. Multiple third positioning holes 22 are provided on the left end of the blade support 16. A positioning bolt 23 is threaded inside the third positioning hole 22. The outer periphery of the middle part of the positioning bolt 23 is threaded inside the second positioning hole 21. The outer periphery of the left end of the positioning bolt 23 is threaded inside the first positioning hole 14. A coolant pipe 11 is movably connected inside the vibrating core 7. The left and right ends of the coolant pipe 11 are fixedly connected to the outside of the damping support 12.

[0028] The screw cover 1 is fixed to the worktable with the fixing bolt 25, so that the upper end of the screw cover 1 is adapted to the lower right end of the cutter body 3. The support seat 2 is installed on the screw cover 1 with the fixing bolt 25. The mutual cooperation between the support seat 2 and the screw cover 1 fixes the rotation position of the cutter body 3. Fixed damping and vibration reduction are achieved at the right end of the cutter body 3. The multi-damping combination reduces the error caused by vibration during workpiece processing. After processing, a cooling pipe is connected to the right end of the first liquid inlet 4, and coolant is introduced. The liquid flows to the fifth liquid inlet 24 and flows outward. The flowing coolant contains a large kinetic energy, which acts on the left end of the blade support 16 and acts in the opposite direction on the vicinity of the cutting blade 17. The waste generated during processing is washed away by the liquid, and the debris generated during processing is prevented from locking the cutting blade 17. The cutting blade 17 is cooled by actively flushing the cutting blade 17.

[0029] Working principle: When the workpiece needs to be undercut, the rubber damper 10 is installed around the damping support 12. The rubber damper 10 installed on the right end of the second limiting block 8 is installed on the left end of the vibrating core 7. The rubber damper 10 installed on the left end of the first limiting block 5 is installed on the right end of the vibrating core 7. During installation, the fourth liquid inlet 15 needs to be aligned with the center of the coolant pipe 11. The assembled vibrating core 7 is installed inside the damping groove 26 opened on the left end of the tool body 3, so that the center of the first liquid inlet 4 is aligned with the center of the second liquid inlet 6. The fixed circular plate 9 is fixedly connected to the left end of the blade body 3, aligning the centers of the third infusion port 13 and the fifth infusion port 24. The centers of the first positioning hole 14 and the second positioning hole 21 correspond one-to-one. The screw cover 1 is fixed to the worktable with the fixing bolt 25, so that the upper end of the screw cover 1 is adapted to the lower right end of the blade body 3. The support base 2 is installed on the screw cover 1 with the fixing bolt 25. Then, the positioning bolt 23 is passed through the third positioning hole 22 and the second positioning hole 21, and the blade support 16 is installed on the left side of the fixed circular plate 9. From the left side, rotate the cutter body 3 clockwise. This causes the rotary bearing 20 to receive the centrifugal force generated by the rotation of the cutter body 3, causing the rotary bearing 20 to rotate around the rotary shaft 19 until the cutting insert 17 unfolds. The cutter body 3 then advances to the right, and the cutting edge 18 at the right end of the cutting insert 17 acts on the workpiece to process it. After processing, connect the cooling pipe to the right end of the first liquid inlet 4 and introduce coolant. The coolant flows to the fifth liquid inlet 24 and flows outward. The flowing coolant contains a large amount of kinetic energy, which acts on the left end of the blade support 16 and in the opposite direction near the cutting insert 17. This washes away the debris generated during processing, preventing the debris from locking the cutting insert 17. Then, remove the cooling pipe from the right end of the first liquid inlet 4. From the left side, rotate the cutter body 3 counterclockwise. This causes the cutting insert 17 to be subjected to centrifugal force in the opposite direction and retract towards the inside of the blade support 16. The cutter body 3 continues to advance to the right, causing the blade support 16 to retract to the right, completing the workpiece operation.
