[0030] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0031] Example 1:
[0032] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of an automatic CNC tool grinding machine, including a base 4. A lifting mechanism 1, a controller 3, a tool changer 5, and a cross slide 8 are arranged on the upper side of the base 4. A support frame 21 is fixedly arranged at the output end of the lifting mechanism 1. A motor 11 is arranged on one side of the support frame 21. A grinding wheel 13 is fixedly arranged at the output end of the motor 11. A tool setter 12 is arranged on the upper side of the support frame 21. Multiple tool placement slots 7 are evenly opened on one side of the tool changer 5. A drive mechanism 9 is fixedly arranged at the output end of the cross slide 8. A chuck seat 15 is threadedly connected to the output end of the drive mechanism 9. A chuck 16 is arranged between the inner wall of the chuck seat 15 and the output end of the drive mechanism 9. The outer wall of the chuck 16 passes through one side of the chuck seat 15. A tool 19 is arranged on one side of the chuck 16. A tool changing assembly 17 is arranged on the outer wall of the chuck seat 15. The tool 19 and the tool placement slots 7 are located at the same horizontal height.
[0033] Specifically, controller 3 can be a PLC programmable controller with an embedded CNC system, and lifting mechanism 1 is a linear module; chuck 16 can be an ER chuck, and chuck seat 15 can be an ER chuck seat. By continuously tightening chuck seat 15, chuck 16 will be pushed to move axially along the inner conical surface of chuck seat 15, thereby converting the axial force of chuck 16 into radial clamping force; tool 19 is a CNC tool that needs to be ground; tool setter 12 is used for calibrating and positioning the position of tool 19, and also for positioning the position of tool 19 to be processed. All of the above are existing technologies.
[0034] When using this grinding machine, CNC tools are sequentially placed into the tool holder 7 on one side of the tool changer 5. The chuck 16 is in the default open state. The tool holder 7 and chuck 16 are designed to be at the same horizontal level. The controller 3 controls the drive of the cross slide 8, and the cross slide 8 is connected to the drive mechanism 9 via a rotational connection. The drive mechanism 9 moves to face the tool holder 7, so that the center of the chuck 16 is aligned with the tool 19 in the tool holder 7, and one end of the tool 19 enters the chuck 16. At this point, the output end of the drive mechanism 9 is connected to the chuck seat 15 via a threaded connection. The interference of the tool changing assembly 17 with the chuck 15 keeps the chuck 15 stationary. The rotation of the output end of the drive mechanism 9 causes the chuck 15 and the output end of the drive mechanism 9 to be continuously screwed together, thereby pushing the chuck 16 to move axially along the inner conical surface of the chuck 15. The axial force of the chuck 16 is converted into a radial clamping force, causing the chuck 16 to retract inward, thus completing the fixation of the tool 19. Then, under the control of the controller 3, the tool 19 is ground by the drive of the cross slide 8 and the lifting mechanism 1, and by the cooperation of the motor 11 and the grinding wheel 13.
[0035] After grinding is completed, the tool 19 is inserted into the corresponding tool slot 7 by driving the cross slide 8. Driven by the output end of the drive mechanism 9 and by the interference of the tool changer 17 on the chuck 15, the chuck 16 is loosened from the output end of the drive mechanism 9, thereby releasing the tool 19 from the lock. The above steps are repeated. Driven by the cross slide 8 and by the cooperation of the drive mechanism 9 and the tool changer 17, the next tool 19 is clamped and ground. This solves the problem of reduced production efficiency caused by a large amount of manual intervention when switching CNC tool types and batch processing.
[0036] Reference Figure 1 Figure 2 and Figure 8The drive mechanism 9 includes a bearing 95. The lower side of the outer ring of the bearing 95 is fixedly connected to the output end of the cross slide 8. A gear 91 is fixedly connected to the outer wall of the bearing 95. The tooth end of the gear 91 is meshed with a gear 93. A drive housing 90 is fixedly connected to the upper side of the inner ring of the bearing 95. A motor 94 and a motor 96 are arranged inside the drive housing 90. The output end of the motor 96 is fixedly arranged above the gear 93. A drive rod 92 is fixedly arranged at the output end of the motor 94. The outer wall of the drive rod 92 passes through one side of the drive housing 90. The outer wall of the end of the drive rod 92 away from the drive housing 90 is threadedly connected to the inner wall of the chuck seat 15. The chuck 16 is arranged between one side of the drive rod 92 and the inner wall of the chuck seat 15.
[0037] Specifically, the fixed connection between the output end of the cross slide 8 and the lower side of the outer ring of the bearing 95 provides support for the outer ring of the bearing 95 and the gear 91. The relative rotation of the inner and outer rings of the bearing 95 drives the gear 93 to rotate through the output end of the motor 96. The meshing connection between the tooth ends of the gear 93 and the tooth ends of the gear 91 causes the reaction force of the rotation of the gear 93 to act on the motor 96. The motor 96 is supported by the drive housing 90, thereby realizing the function of relative rotation between the drive mechanism 9 and the cross slide 8. The drive of the output end of the motor 94 drives the drive rod 92 to rotate, which in turn drives the chuck 16 to rotate, causing the tool 19 to rotate. The threaded connection between the outer wall of the drive rod 92 and the inner wall of the chuck seat 15 enables the chuck 16 to lock the tool 19.
[0038] Reference Figure 1 and Figure 3 A correction rod 10 is fixedly connected to one side of the tool changer 5. The correction rod 10 and the tool placement groove 7 are at the same height. A tool placement opening 6 is opened on the other side of the tool changer 5. The tool placement opening 6 and the middle of the tool placement groove 7 are connected.
[0039] Specifically, the CNC system of controller 3, in cooperation with the cross slide 8, establishes a two-dimensional plane coordinate system for the movement position of the drive mechanism 9. Driven by the cross slide 8, and by monitoring the rotational speed, angle, and position of motors 3 (96) and 2 (94), the position of the chuck 16 in the coordinate system can be obtained in real time. The design of the tool release slot 6 improves the convenience of loading and unloading the tool 19 from the tool release slot 7. A pressure sensor 2 is installed inside the correction rod 10. Since the correction rod 10 and the tool release slot 7 are at the same height, and consequently, it is also at the same height as the chuck seat 15, when it is necessary to load or unload the tool 19 from the tool release slot 7, the cross slide 8... Driven by the motor 396, the chuck 15 rotates to face the tool slot 7. Driven by the cross slide 8, the outer wall of the chuck 15 contacts the outer wall of the correction rod 10, applying pressure to the outer wall of the correction rod 10. Since the position of the correction rod 10 is fixed, the position data of the chuck 15 can be corrected by the feedback of the correction rod 10 signal and then processed and analyzed by the controller 3, thereby improving the accuracy of the tool 19 position. By controlling the drive of the cross slide 8 through preset data, the chuck 16 can accurately pick up and put down the tool 19, thus helping to improve the tool 19 replacement efficiency of the grinding machine.
[0040] Reference Figure 3 A positioning bracket 14 is fixedly connected to the upper side of the support frame 21. The tool setter 12 is set at the end of the positioning bracket 14 away from the lifting mechanism 1. A protective cover 2 is provided on one side of both the lifting mechanism 1 and the cross slide 8.
[0041] Specifically, the protective cover 2 is a telescopic bellows protective cover used to shield the lifting mechanism 1 and the cross slide 8. The support frame 21 provides support for the positioning bracket 14, and in turn provides support for the tool setter 12, thereby helping to realize the function of positioning the tool 19.
[0042] Reference Figure 3 and Figure 4 Multiple rubber sleeves 22 are fixedly connected to one side of the tool changer 5. The outer wall of the rubber sleeve 22 is fixedly connected to the inner wall of the tool slot 7. The outer wall of the tool 19 and the inner wall of the rubber sleeve 22 are fitted with a clearance.
[0043] Specifically, the rubber sleeve 22 and the inner wall and the outer wall of the tool 19 are fitted with a clearance. Through the friction between the rubber sleeve 22 and the tool 19, the chuck 16 can avoid pulling the tool 19 out when it puts the tool 19 into the tool slot 7 and pulls itself out, thereby helping to improve the tool 19 replacement efficiency.
[0044] Refer to Figure 2 ,and Figure 3 and Figure 8The tool changing assembly 17 includes a tool changing block 18. One side of the tool changing block 18 is fixedly connected to the outer wall of the chuck seat 15. A plurality of tool changing rods 20 are fixedly connected to one side of the tool changing frame 5. The tool changing rods 20 and the tool placement groove 7 are at the same height. Grooves matching the outer wall of the tool changing rods 20 are opened on both sides of the tool changing block 18.
[0045] Specifically, when the tool 19 is picked up or put down, the drive rod 92 is driven by the output end of the motor 2 94 to rotate, which in turn drives the chuck seat 15 to rotate. This causes the tool changing block 18 to rotate with the chuck seat 15 and rotate until it fits into the groove on the tool changing rod 20. As the drive rod 92 continues to rotate, the chuck seat 15 and the drive rod 92 are tightened or loosened, thus releasing or tightening the tool 19 held by the chuck 16. This achieves the function of the tool changing assembly 17 in changing the tool 19.
[0046] Example 2:
[0047] Reference Figure 5 , Figure 6 and Figure 7 This utility model also provides an embodiment in which the tool changing assembly 17 includes a cylinder 25, which is disposed on the upper side of the cross slide 8. A tool changing rod 26 is fixedly disposed at the output end of the cylinder 25. A positioning rod 27 is fixedly connected to the outer wall of the tool changing rod 26. A pressure sensor 28 is disposed on the upper outer wall of the positioning rod 27. One side of the pressure sensor 28 is in contact with the outer wall of the chuck seat 15. A tool changing block 23 is fixedly connected to the outer wall of the chuck seat 15. A circular hole 24 is opened on the side of the tool changing block 23 away from the chuck seat 15. The upper outer wall of the tool changing rod 26 is slidably connected to the inner wall of the circular hole 24.
[0048] Specifically, the positioning rod 27 is L-shaped. In this embodiment, when the tool 19 needs to be replaced, the drive mechanism 9 is moved to the side close to the edge of the base 4 by the drive of the cross slide 8. The chuck seat 15 is moved close to the upper end of the positioning rod 27 by the continuous drive of the cross slide 8.
[0049] When the outer wall of the chuck 15 and the upper L-shaped inner side of the positioning rod 27 are in contact, the pressure sensor 28 and the chuck 15 are at the same height, causing the chuck 15 to exert pressure on the pressure sensor 28. Through processing and analysis by the controller 3, the position of the chuck 15 is calibrated. Then, driven by the cross slide 8, the outer wall of the tool 19 contacts the pressure sensor 28, thereby completing the horizontal calibration of the chuck 15.
[0050] Driven by the output of motor 294, the drive rod 92 rotates, which in turn drives the tool changer 23 to rotate until it aligns with the tool changer 26. Driven by the output of cylinder 25, the tool changer 26 moves upward and slides into the round hole 24, interfering with the chuck seat 15. By rotating the drive rod 92 at a certain angle, the tool 19 is slightly loosened to the point where it can be pulled out by friction with the rubber sleeve 22, but without falling off. Then, driven by the cross slide 8, which is connected to the drive mechanism 9, the tool 19 is picked up and put in from the tool slot 7, thus realizing the function of tool changer 17 to change tool 19.
[0051] Reference Figure 1 , Figure 7 and Figure 8 The controller 3 is electrically connected to the lifting mechanism 1, motor 2 94, motor 3 96, motor 1 11, tool setter 12, cylinder 25, and pressure sensor 1 28.
[0052] Specifically, the controller 3 controls the lifting mechanism 1 to drive the grinding wheel 13 to move up and down. The controller 3 controls the motor 2 94 to drive the drive rod 92 to rotate. The controller 3 controls the motor 3 96 to drive the drive mechanism 9 and the cross slide 8 to rotate. The controller 3 controls the tool setter 12 to position the tool 19. The controller 3 controls the cylinder 25 to drive the tool, and the pressure sensor 28 provides feedback to change the tool 19, thus realizing the intelligent control function of the grinding machine.
[0053] Working principle: When using this grinding machine, CNC tools are placed into the tool slot 7 on one side of the tool changer 5 in sequence; the chuck 16 is in the default open state. The tool slot 7 and the chuck 16 are designed to be at the same horizontal level. The cross slide 8 is driven by the controller 3. The output of the motor 3 96 drives the gear 2 93 to rotate, so as to realize the relative rotation of the cross slide 8 and the drive housing 90.
[0054] When the tool changing assembly 17 consists of a tool changing block 18 and a tool changing rod 20, the chuck 15 moves to face the tool placement slot 7 through the drive of the cross slide 8 and the cooperation of the drive mechanism 9. The drive rod 92 is driven by the output of the motor 2 94, which rotates the chuck 15. The tool changing block 18 rotates with the chuck 15 and rotates to fit into the groove on the tool changing rod 20. With the continued rotation of the drive rod 92, the chuck 15 and the drive rod 92 are tightened or loosened, releasing or clamping the tool 19 held by the chuck 16, thus realizing the function of the tool changing assembly 17 to change the tool 19.
[0055] If the tool changing assembly 17 consists of a tool changing block 23, a round hole 24, a cylinder 25, a tool changing lever 26, a positioning rod 27, and a pressure sensor 28, when the tool 19 needs to be replaced, the drive mechanism 9 is moved by the drive of the cross slide 8, so that the chuck 15 and the tool 19 exert pressure on the pressure sensor 28 in sequence. Through the processing and analysis of the controller 3, the position of the chuck 15 is calibrated. Through the drive of the output end of the motor 24, the drive rod 92 is rotated, which in turn drives the tool changing block 23 to rotate until it is aligned with the tool changing lever 26. Through the drive of the output end of the cylinder 25, the tool changing lever 26 is moved upward and slides into the round hole 24, interfering with the chuck 15, thus completing the fastening and loosening of the tool 19. Then the tool 19 is taken out and put in from the tool slot 7, thereby realizing the function of the tool changing assembly 17 to replace the tool 19.
[0056] After grinding a tool 19, repeat the above steps to solve the problem of reduced production efficiency caused by the need for a lot of manual intervention when switching CNC tool types and batch processing.
[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
