Detailed implementation manners

[0024] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] The present invention provides a rotary machining machine equipped with a boring equipment, as Figures 1 to 3 shown, including a tool shank assembly, wherein the tool shank assembly includes: a cutting head 7, a tool shank 8, a taper shank 9 and a copper nozzle 10. In Figure 1 this case, taking the tool shank assembly as an example for illustration, the cutting head 7 is located at the front side of the tool shank 8. The tool shank 8 is arranged as a hollow pipe fitting. The cutting head 7 is fixed to the front side of the tool shank 8, and a plurality of water outlets 701 are provided on the surface of the cutting head 7. The taper shank 9 is fixed to the rear side of the tool shank 8, and the taper shank 9 is correspondingly clamped inside the bayonet 6 of the clamping frame 2. A water through groove 801 is provided inside the tool shank 8. A copper nozzle 10 is provided on the surface of the tool shank 8. The copper nozzle 10 is communicated with a plurality of water outlets 701 by means of the water through groove 801. A cold water pipe is connected to the surface of the copper nozzle 10, and the cold water inside the cold water pipe passes through the copper nozzle 10 and the water through groove 801 to supply water to the water outlets 701. A plurality of cutting inserts 702 are fixed to the surface of the cutting head 7 by means of screws.

[0026] A moving frame 24 is provided at the front side of the tool shank assembly. A three-jaw chuck 25 is provided on the rear side of the moving frame 24. The moving frame 24 clamps the workpiece 1 to be machined by means of the three-jaw chuck 25. A drilling hole is provided on the rear side of the workpiece 1 to be machined, and the cutting head 7 of the tool shank assembly corresponds to the drilling hole on the rear side of the workpiece 1. The moving frame 24 is slidably placed on the top of the chassis 26, and the output end of an external cylinder is connected to the moving frame 24. A power device is built in the moving frame 24, and the power device drives the three-jaw chuck 25 to rotate.

[0027] Specifically, insert the taper shank 9 of the tool bar assembly into the bayonet 6 of the clamping bracket 2. At this time, the clamping assembly clamps the taper shank 9 of the tool bar assembly, and the tool tip 7 of the tool bar assembly corresponds to the workpiece 1 to be machined. The workpiece 1 to be machined is installed at the rear side of the three-jaw chuck 25. The power equipment operates, and the power equipment drives the three-jaw chuck 25 to rotate. The rotating three-jaw chuck 25 drives the workpiece 1 to rotate. At this time, the air cylinder operates, and the output end of the air cylinder pushes the moving frame 24 to slide on the top surface of the chassis 26. The sliding moving frame 24 gradually approaches the tool tip 7 of the tool bar assembly until the tool tip 7 contacts the rear side of the workpiece 1, and the rotating workpiece 1 rotates at the front end of the tool tip 7.

[0028] When the three-jaw chuck 25 makes the workpiece 1 rotate, the driving assembly makes the clamping assembly rotate. The rotating clamping assembly uses the taper shank 9 to make the tool bar 8 drive the tool tip 7 to rotate. The rotation direction of the tool tip 7 is opposite to the rotation direction of the workpiece 1. The rotating tool tip 7 uses multiple cutting grains 702 to perform boring on the drilled hole on the surface of the workpiece 1. When the workpiece 1 is being bored, the cold water inside the cold water pipe passes through the copper nozzle 10 and the water trough 801 to the water outlet 701. The cold water is sprayed on the rear side of the workpiece 1 and the surface of the tool tip 7 through the water outlet 701, and the cold water is used to cool the workpiece 1 and the tool tip 7, accelerating the boring efficiency of the workpiece 1.

[0029] In order to perform boring on the workpiece 1, the driving assembly is used to make the tool bar assembly rotate. In Figure 1 , the driving assembly includes: a stepper motor 27, a gear 28, a turntable 29, and a belt 30. A limiting frame 31 is installed at the top of the chassis 26. A stepper motor 27 is installed on one side of the limiting frame 31. The gear 28 is drivingly connected to the output end of the stepper motor 27. The turntable 29 is located at the rear side of the limiting frame 31. A plurality of teeth are provided on the front side surface of the turntable 29, and the teeth are in driving cooperation with the gear 28 through the belt 30. The center of the front side of the turntable 29 is connected to the center of the rear side surface of the clamping bracket 2 through a rotating rod 3, and the rotating rod 3 passes through the center of the limiting frame 31.

[0030] Specifically, start the stepper motor 27. The gear 28 at the output end of the stepper motor 27 rotates. The rotating gear 28 makes the turntable 29 rotate through the belt 30 and the teeth. The rotating turntable 29 drives the clamping bracket 2 to rotate through the rotating rod 3. The clamping bracket 2 makes the tool bar assembly rotate through the clamping assembly. At the same time, the power equipment drives the three-jaw chuck 25 to rotate. The rotation direction of the tool bar assembly is opposite to the rotation direction of the three-jaw chuck 25, and the rotating tool bar assembly is used to perform boring on the workpiece 1.

[0031] Among them, in order to bore the workpiece 1, the stepping motor 27 limits the gear 28, and the gear 28 uses the belt 30 and the turntable 29 to limit the clamping bracket 2 at the front end of the rotating rod 3, thereby locking the tool rod assembly. The power device drives the three-jaw chuck 25 to rotate, and the output end of the cylinder drives the three-jaw chuck 25 and the workpiece 1 to approach the locked tool rod assembly through the moving bracket 24. At this time, the rotating workpiece 1 rotates at the front end of the cutting head 7, and the locked tool rod assembly bores the workpiece 1.

[0032] The taper shank 9 of the tool rod assembly is inserted into the bayonet 6 of the clamping bracket 2, and the rear side of the tool rod assembly is clamped by the buckle mechanism. Figures 1 to 5 Among them, the buckle mechanism includes: a pressure plate 11 and a rotating plate 12. The rotating plate 12 is installed on the outer side surface of the pressure plate 11 by a connecting member. The outer side part of the pressure plate 11 is connected to an elastic structure by the rotating plate 12. Two relatively arranged side frames 22 are fixed on the outer circumferential surface of the clamping bracket 2. A side groove corresponding to the pressure plate 11 is opened on the rear side surface of the side frame 22. The two pressure plates 11 correspond to the two side frames 22 one by one. The pressure plate 11 slides inside the side groove. A pressure rod 4 is fixed to the inner end of the pressure plate 11, and a clamping head 5 is fixed to the inner end of the pressure rod 4. Notches 901 are provided on both the top surface and the bottom surface of the taper shank 9.

[0033] Specifically, when the taper shank 9 of the tool rod assembly is inserted into the bayonet 6 of the clamping bracket 2, the elastic structure uses the rotating plate 12 to make the pressure plate 11 approach the taper shank 9. The pressure plate 11 uses the pressure rod 4 to make the clamping head 5 inserted into the notch 901 of the taper shank 9. At this time, the two clamping heads 5 clamp the taper shank 9 of the tool rod assembly by means of the notch 901.

[0034] The cylinder works. The output end of the cylinder drives the workpiece 1 to squeeze the cutting head 7 through the three-jaw chuck 25 at the rear side of the moving bracket 24. The pressure of the workpiece 1 on the cutting head 7 makes the taper shank 9 of the tool rod assembly stably clamped inside the bayonet 6 of the clamping bracket 2, and the elastic member makes the clamping head 5 at the inner end of the pressure rod 4 clamped inside the notch 901 of the taper shank 9, thereby ensuring the stability of the tool rod assembly at the front side of the clamping bracket 2.

[0035] In order to clamp the taper shank 9, the elastic structure is used to make the clamping head 5 clamped inside the notch 901. Figure 4 and Figure 5Among them, the elastic structure includes: side tubes 16, insertion rods 17, limiting rods 18, elastic members 19, moving rods 20 and rotating sleeves 21. The elastic member 19 is set as a spring plate. The two side tubes 16 are relatively located inside the side grooves of the side frame 22, and the center lines of the two side tubes 16 coincide. The limiting rod 18 is located between the two side tubes 16. The inner ends of the side tubes 16 are sleeved on the ends of the limiting rod 18. The inner ends of the side tubes 16 are fixed with insertion rods 17. The inner ends of the insertion rods 17 are inserted into the outer ends of the rotating plate 12. The outer ends of the side tubes 16 are connected with sliding rods 23. The inner side walls of the side grooves are provided with arc grooves 201, and the side tubes 16 slide inside the arc grooves 201 by means of the sliding rods 23. The two side tubes 16 are connected by the elastic member 19, and the elastic member 19 is in a compressed state. A moving rod 20 is fixed at the center of the limiting rod 18. The moving rod 20 correspondingly penetrates through the end of the side frame 22, and the rotating sleeve 21 is rotationally clamped at the end of the side frame 22. The rotating rotating sleeve 21 is spirally sleeved on the surface of the moving rod 20. The moving rod 20 includes a threaded portion and a smooth portion. The threaded portion is located on the outer side of the smooth portion, and the rotating sleeve 21 is in spiral cooperation with the threaded portion of the moving rod 20.

[0036] Working process one: When the rotating sleeve 21 is spirally sleeved on the threaded portion of the moving rod 20, rotate the rotating sleeve 21. Since the rotating sleeve 21 is rotationally clamped at the end of the side frame 22, the rotating rotating sleeve 21 causes the moving rod 20 to move. The moving moving rod 20 pushes the side tubes 16 to move synchronously by means of the limiting rod 18. The side tubes 16 move inside the arc grooves 201 by means of the sliding rods 23. When the side tubes 16 approach the clamping bracket 2, since the arc grooves 201 limit the side tubes 16 by means of the sliding rods 23, the two downward-moving side tubes 16 are separated from each other. At this time, the elastic member 19 gradually expands; when the side tubes 16 are away from the clamping bracket 2, the two downward-moving side tubes 16 approach each other, and the two approaching side tubes 16 cooperate to squeeze the elastic member 19.

[0037] Since the rotating sleeve 21 limits the moving rod 20 by means of the threaded portion, at this time, the moving rod 20 locks the side tubes 16 by means of the limiting rod 18. The side tubes 16 limit the rotating plate 12 by means of the insertion rods 17, preventing the rotating plate 12 from rotating, and further preventing the pressing plate 11 from moving inside the side groove of the side frame 22. At this time, the pressing rod 4 at the inner side of the pressing plate 11 is clamped inside the notch 901 by means of the chuck 5, ensuring the locking effect of the taper shank 9 inside the bayonet 6 and preventing the tool rod assembly from separating from the clamping bracket 2 due to simple pulling.

[0038] Working process two: When the rotating sleeve 21 is sleeved on the smooth surface of the moving rod 20, the pressing plate 11 is toggled away from the clamping bracket 2. The pressing plate 11 drives the chuck 5 away from the bayonet 6 by means of the pressure rod 4. The pressing plate 11 makes the inner end of the rotating plate 12 move by means of the connecting component. At this time, the rotating plate 12 rotates inside the side groove. The rotating rotating plate 12 makes the side tube 16 move by means of the inserting rod 17. At this time, the side tube 16 moves away from the clamping bracket 2. The two side tubes 16 cooperate to squeeze the elastic member 19. The side tube 16 makes the moving rod 20 move by means of the limiting rod 18. At this time, the moving rod 20 moves inside the rotating sleeve 21 by means of the smooth part. When the taper shank 9 is inserted into the bayonet 6 and the notch 901 of the taper shank 9 corresponds to the chuck 5, the pulling force applied to the pressing plate 11 is released. The elastic force of the elastic member 19 makes the two side tubes 16 separate. At this time, the side tube 16 slides inside the arc-shaped groove 201 by means of the sliding rod 23. The moving side tube 16 approaches the clamping bracket 2. The inward-moving side tube 16 makes the outer ends of the two rotating plates 12 separate from each other. At this time, the rotating rotating plate 12 makes the chuck 5 snap into the notch 901 by means of the pressure rod 4, and uses the elastic force of the elastic member 19 to ensure that the taper shank 9 is snapped into the bayonet 6 inside.

[0039] Pull the tool bar assembly. The moving tool bar assembly drives the taper shank 9 away from the clamping bracket 2. The moving taper shank 9 makes the two chucks 5 separate from each other by means of the notch 901. The chuck 5 makes the pressing plate 11 move outward by means of the pressure rod 4. The outward-moving pressing plate 11 makes the two side tubes 16 squeeze the elastic member 19 by means of the rotating plate 12, providing a damping effect for the pulling of the tool bar assembly and preventing the tool bar assembly from directly falling from the front side of the clamping bracket 2.

[0040] In order to quickly separate the tool bar assembly from the clamping bracket 2, the connecting component is used to drive the rotating plate 12 to move. In Figure 4 and Figure 5 the connecting component includes: an inner rod 13, a push plate 14 and a pull rod 15. The two pull rods 15 are correspondingly inserted into the rear side of the pressing plate 11. A push plate 14 is fixed at the front end of the pull rod 15. A chute corresponding to the push plate 14 is provided on the outer side of the pressing plate 11. And an inner rod 13 is fixed to the rear side of the push plate 14. The two rotating plates 12 correspond to the two pull rods 15 one by one. The inner end of the rotating plate 12 is sleeved on the surface of the inner rod 13. And the rear ends of the two pull rods 15 are connected by a pull plate 151.

[0041] Specifically, pull the pull plate 151 backward. The backward-moving pull plate 151 makes the push plate 14 move backward by means of the pull rod 15. The push plate 14 moves inside the chute. The push plate 14 makes the outer end of the rotating plate 12 move backward on the surface of the inserting rod 17 until the rear end of the rotating plate 12 is separated from the inserting rod 17. At this time, the side tube 16 cannot limit the pressing plate 11 by means of the rotating plate 12, so that the taper shank 9 of the tool bar assembly can be quickly withdrawn from the bayonet 6 of the clamping bracket 2, completing the quick separation of the tool bar assembly from the clamping bracket 2.

[0042] The working principle of the present invention:

[0043] Referring to Figures 1 to 5 As shown, when the rotating sleeve 21 is spirally sleeved on the surface of the threaded portion of the moving rod 20, since the rotating sleeve 21 is rotationally clamped at the end of the side frame 22, the rotating rotating sleeve 21 causes the moving rod 20 to move. The moving moving rod 20 uses the limiting rod 18 to push the side tube 16 to move synchronously. The side tube 16 moves inside the arc-shaped groove 201 by means of the sliding rod 23. When the side tube 16 moves away from the clamping bracket 2, the two downward-moving side tubes 16 approach each other. The two approaching side tubes 16 cooperate to squeeze the elastic member 19. The moving side tube 16 uses the rotating turning plate 12 to move the pressing plate 11 away from the clamping bracket 2. At this time, the pressing plate 11 uses the pressing rod 4 to drive the chuck 5 away from the bayonet 6. When the taper shank 9 of the tool rod assembly is inserted into the bayonet 6 of the clamping bracket 2 at this time, the reversely rotating rotating sleeve 21 causes the side tube 16 to approach the clamping bracket 2. The rotating turning plate 12 causes the pressing plate 11 to approach the clamping bracket 2. The pressing plate 11 uses the pressing rod 4 to drive the chuck 5 to approach the bayonet 6 until the chuck 5 is clamped inside the notch 901. Since the rotating sleeve 21 uses the threaded portion to limit the moving rod 20, at this time, the moving rod 20 uses the limiting rod 18 to lock the side tube 16. The side tube 16 limits the turning plate 12 through the insertion rod 17 to prevent the turning plate 12 from rotating, thereby preventing the pressing plate 11 from moving inside the side groove of the side frame 22. At this time, the pressing rod 4 on the inner side of the pressing plate 11 uses the chuck 5 to be clamped inside the notch 901, ensuring the locking effect of the taper shank 9 inside the bayonet 6 and preventing the tool rod assembly from separating from the clamping bracket 2 due to simple pulling and pushing.

[0044] When the rotating sleeve 21 is sleeved on the surface of the smooth portion of the moving rod 20, the pressing plate 11 is toggled away from the clamping bracket 2. The pressing plate 11 uses the pressing rod 4 to drive the chuck 5 away from the bayonet 6. The pressing plate 11 uses the connecting component to move the inner end of the turning plate 12. At this time, the turning plate 12 rotates inside the side groove. The rotating turning plate 12 uses the insertion rod 17 to move the side tube 16. At this time, the side tube 16 moves away from the clamping bracket 2. The two side tubes 16 cooperate to squeeze the elastic member 19. The side tube 16 uses the limiting rod 18 to move the moving rod 20. At this time, the moving rod 20 moves inside the rotating sleeve 21 by means of the smooth portion. When the taper shank 9 is inserted into the bayonet 6 and the notch 901 of the taper shank 9 corresponds to the chuck 5, the pulling force applied to the pressing plate 11 is released. The elastic force of the elastic member 19 causes the two side tubes 16 to separate. At this time, the side tube 16 slides inside the arc-shaped groove 201 by means of the sliding rod 23. The moving side tube 16 approaches the clamping bracket 2. The inward-moving side tube 16 causes the outer ends of the two turning plates 12 to separate from each other. At this time, the rotating turning plate 12 uses the pressing rod 4 to cause the chuck 5 to be clamped inside the notch 901, using the elastic force of the elastic member 19 to ensure that the taper shank 9 is clamped inside the bayonet 6.

[0045] After defining the tool bar assembly, the moving frame 24 uses a three-jaw chuck 25 to clamp the workpiece 1 to be machined. A drilling hole is provided on the rear side of the workpiece 1 to be machined, and the cutting head 7 of the tool bar assembly corresponds to the drilling hole on the rear side of the workpiece 1. The power equipment operates, and the power equipment drives the three-jaw chuck 25 to rotate. The rotating three-jaw chuck 25 drives the workpiece 1 to rotate. At this time, the cylinder operates, and the output end of the cylinder pushes the moving frame 24 to slide on the top surface of the chassis 26. The sliding moving frame 24 gradually approaches the cutting head 7 of the tool bar assembly until the cutting head 7 contacts the rear side of the workpiece 1. The rotating workpiece 1 rotates in front of the cutting head 7.

[0046] When the three-jaw chuck 25 rotates the workpiece 1, the driving assembly rotates the clamping assembly. The rotating clamping assembly uses the taper shank 9 to make the tool bar 8 drive the cutting head 7 to rotate. The rotation direction of the cutting head 7 is opposite to the rotation direction of the workpiece 1. The rotating cutting head 7 uses multiple cutting grains 702 to perform boring on the drilling hole on the surface of the workpiece 1. When the workpiece 1 is being bored, the cold water inside the cold water pipe passes through the copper nozzle 10 and the water trough 801 to the water outlet 701. The cold water is sprayed on the rear side of the workpiece 1 and the surface of the cutting head 7 through the water outlet 701, and the cold water is used to cool the workpiece 1 and the cutting head 7, accelerating the boring efficiency of the workpiece 1.

[0047] After the boring of the workpiece 1 is completed, the output end of the cylinder pulls the moving frame 24 away from the cutting head 7. Until the workpiece 1 is completely separated from the cutting head 7, the power equipment and the stepping motor 27 stop working. The bored workpiece 1 is removed from the three-jaw chuck 25, and the boring of the workpiece 1 is completed. At this time, a new workpiece 1 can be re-clamped on the three-jaw chuck 25, which is convenient for continuous boring of multiple workpieces 1.

[0048] When it is necessary to extract the tool bar assembly, pull the pull plate 151 backward. The backward moving pull plate 151 uses the pull rod 15 to make the push plate 14 move backward. The push plate 14 moves inside the sliding groove. The push plate 14 makes the outer end of the rotating plate 12 move backward on the surface of the inserting rod 17 until the rear end of the rotating plate 12 is separated from the inserting rod 17. At this time, the side pipe 16 cannot use the rotating plate 12 to limit the pressing plate 11, so that the taper shank 9 of the tool bar assembly can be quickly extracted from the bayonet 6 of the clamping frame 2, completing the quick separation of the tool bar assembly and the clamping frame 2.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
