Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a tool length adjusting pin mechanism. Background Technology

[0002] Heat-shrink tool holders are high-precision tool clamping systems based on the principle of thermal expansion. They achieve clamping by utilizing the difference in thermal expansion coefficients between a special stainless steel tool holder and a carbide tool. They are primarily used in precision manufacturing fields such as milling, drilling, mold making, and aerospace. Their working principle involves heating the tool holder to approximately 300°C and then inserting it into the tool. The metal cools and contracts, forming a strong fixation. The runout accuracy can reach 0.0025mm, and the dynamic balance stability is superior to traditional collet structures.

[0003] When installing milling cutters in commercially available heat shrink tool holders, the milling cutter is usually inserted manually into the heated heat shrink tool holder. Since the installation depth of the milling cutter can only be judged by visual inspection, the installation depth is uncontrollable and has a large error. To address this, we designed a pin mechanism to adjust the tool length, so as to precisely control the installation depth of the milling cutter and prevent the milling cutter from vibrating when it is running at high speed.

[0023] Example 1, as Figure 1 , Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 12 , Figure 16 As shown, this utility model provides an embodiment of an adjustable tool length ejector pin mechanism 5, including a frame 1, a worktable 4 on the frame 1, a rotating spindle 8 rotatably mounted on the worktable 4, a conversion sleeve body 20 detachably mounted on the upper end of the rotating spindle 8, an ejector pin hole 13 formed in the middle of the rotating spindle 8, an adjusting ejector pin 9 fitted in the ejector pin hole 13 with clearance, and a first lifting mechanism 5.1 fixedly mounted inside the frame 1, the first lifting mechanism 5.1 driving the adjusting ejector pin 9 to move up and down within the conversion sleeve body 20; The principle is as follows: A pin hole 13 is set inside the rotating spindle 8. Since the bottom end of the milling cutter 12 always rests on the adjusting pin 9 after the milling cutter 12 is installed, the first lifting mechanism 5.1 can be used to drive the adjusting pin 9 to move up and down in the pin hole 13, so as to achieve precise positioning of the installation depth of the milling cutter 12 in the heat shrink tool holder 10 and ensure the stability of the milling cutter 12 installation.

[0024] Furthermore: an active motor 38 is fixedly installed inside the frame 1, and the active motor 38 drives the rotating spindle 8 to rotate; the active motor 38 can be used to control the entire rotating spindle 8 to rotate, and the rotating spindle 8 will drive the heat shrink tool holder 10 to rotate, and then the heat shrink tool holder 10 is heated and the installation position is detected during rotation, which has higher accuracy.

[0025] Furthermore: a first pulley 39 is fixedly mounted on the rotor of the active motor 38, and a second pulley 40 is fixedly mounted on the rotating main shaft 8.

[0026] Furthermore, a fixed cylinder 42 is rotatably mounted on the outer side of the rotating spindle 8, and the fixed cylinder 42 and the frame 1 are fixedly connected to each other; this can ensure the stable installation of the rotating spindle 8 within the frame 1.

[0027] Furthermore, the first lifting mechanism 5.1 includes a lifting motor 5.11, a turntable 5.12, and a lifting screw 5.13. The lifting motor 5.11 is fixedly installed inside the frame 1. The turntable 5.12 has a threaded hole formed in the middle. The lifting screw 5.13 is screw-fitted into the threaded hole. The lifting motor 5.11 drives the turntable 5.12 to rotate. The upper end of the lifting screw 5.13 drives the adjusting pin 9 to move up and down. The lifting motor 5.11 can drive the lifting screw 5.13 to move up and down through the turntable 5.12. When the lifting screw 5.13 moves up and down, it can drive the adjusting pin 9 to adjust the height, thereby achieving precise positioning of the milling tool 12 in the heat shrink tool holder 10.

[0028] Furthermore: a third pulley 43 is fixedly installed on the outer side of the turntable 5.12, and a fourth pulley 44 is fixedly installed on the rotor of the lifting motor 5.11. A second transmission belt 45 is installed between the third pulley 43 and the fourth pulley 44; this ensures the stable rotation of the turntable 5.12.

[0029] Furthermore: a first vertical support 47 is fixedly installed inside the frame 1, a vertical guide rail 48 is fixedly installed on the first vertical support 47, a vertical slider 49 is slidably installed on the vertical guide rail 48, and the lower end of the lifting screw 5.13 is fixedly installed on the vertical slider 49; this ensures the stable lifting and lowering movement of the lifting screw 5.13.

[0030] Furthermore: a motor bracket 46 is fixedly installed on the upper end of the first vertical bracket 47, and the lifting motor 5.11 is fixedly installed on the motor bracket 46; this ensures the stable installation of the lifting motor 5.11.

[0031] Furthermore: an L-shaped positioning block 50 is fixedly installed on the vertical slider 49, and slotted photoelectric detectors 51 are fixedly installed at both the upper and lower ends of the first vertical bracket 47. The outer end of the L-shaped positioning block 50 moves into the slotted photoelectric detector 51 with clearance fit; it can detect when the vertical slider 49 rises to the limit position and falls to the limit position respectively, avoiding the vertical slider 49 from excessively rising and falling, causing the lifting screw 5.13 to disengage from the threaded hole of the turntable 5.12, and ensuring its stable lifting and falling control.

[0032] Example 2, as Figure 1-17 As shown, the hot fitting pre-adjustment integrated machine of this utility model includes a frame 1, an intelligent milling cutter cabinet 2 and a tool holder conversion sleeve structure 3. A workbench 4 is provided on the frame 1. An adjusting tool length ejector pin mechanism 5 is fixedly installed inside the frame 1. A hot fitting tool mechanism 6 and a laser measuring mechanism 7 are fixedly installed on the workbench 4. A rotating spindle 8 is rotatably mounted on the worktable 4. An adjusting pin 9 is installed inside the rotating spindle 8 with clearance fit. The tool length adjusting pin mechanism 5 drives the adjusting pin 9 to move up and down. The tool holder conversion sleeve structure 3 conveys several heat shrink tool holders 10, the worktable 4 is equipped with a robot arm 11, the intelligent milling cutter cabinet 2 contains milling cutters 12, the robot arm 11 takes out the milling cutter 12 from the intelligent milling cutter cabinet 2 and installs it into the heat shrink tool holder 10, and the robot arm 11 drives the heat shrink tool holder 10 to be assembled onto the rotating spindle 8. The heat-fitting tool mechanism 6 is heated on the rotating heat-shrink tool holder 10; The laser measurement mechanism 7 performs measurements on the rotating heat-shrinkable tool holder 10.

[0033] The principle is as follows: The heat-shrink tool holder 10 to be installed with the milling cutter 12 is placed in the tool holder conversion sleeve structure 3 for conveying. When it is conveyed to the left side of the robot arm 11, the robot arm 11 takes out the entire heat-shrink tool holder 10 and places it on the rotating spindle 8 of the worktable 4, realizing the automatic feeding action of the heat-shrink tool holder 10. After the heat-shrink tool holder 10 is fed, the heat-fitting tool mechanism 6 heats the heat-shrink tool holder 10. While heating, the rotating spindle 8 drives the heat-shrink tool holder 10 to rotate, achieving the technical effect of uniform heating. The heat-shrink tool holder 10 will expand as the temperature rises, and then drive the heat-fitting tool mechanism 6 away from the heat-shrink tool holder 10. At this time, the milling cutter 12 can be installed in the heat-shrink tool holder 10. Specifically, the robot arm 11 takes out the corresponding milling cutter 12 to be installed from the intelligent milling cutter cabinet 2 and conveys it to be inserted into the heat-shrink tool holder. In step 10, the milling cutter 12 is automatically installed. As the temperature gradually decreases, the heat shrink shank 10 shrinks, thus achieving a stable clamping effect for the milling cutter 12. While installing the milling cutter 12, the adjusting pin 9 can be raised and lowered using the tool length adjusting pin mechanism 5. Since the upper end of the adjusting pin 9 is always against the bottom end of the milling cutter 12, the installation depth of the milling cutter 12 in the heat shrink shank 10 can be controlled by adjusting the height of the pin 9, thus ensuring the stability of the milling cutter 12 installation. Finally, the laser measuring mechanism 7 performs laser detection on the rotating heat shrink shank 10 to accurately determine whether the milling cutter 12 is installed in place, ensuring installation accuracy and making the vibration range of the milling cutter 12 during high-speed rotation controllable, thereby ensuring the service life of the heat shrink shank 10 and the milling cutter 12.

[0034] Furthermore, the tool length adjustment pin mechanism 5 includes a lifting motor 5.11, a turntable 5.12, and a lifting screw 5.13. The lifting motor 5.11 is fixedly installed inside the frame 1. The turntable 5.12 has a threaded hole formed in its center. The lifting screw 5.13 is screw-fitted into the threaded hole. The lifting motor 5.11 drives the turntable 5.12 to rotate. The rotating spindle 8 has a pin hole 13 formed inside. The upper end of the lifting screw 5.13 drives the adjusting pin 9 to move up and down within the pin hole 13. The lifting motor 5.11 drives the turntable 5.12 to rotate, thereby driving the lifting screw 5.13 to move up and down. When the lifting screw 5.13 is adjusting up and down, it can control the height of the adjusting pin 9 within the pin hole 13. The upper end of the adjusting pin 9 presses against the milling tool 12, thereby achieving precise positioning of the clamping depth of the milling tool 12.

[0035] Furthermore, the outer side of the rotating spindle 8 is rotatably fitted with a housing 14, which is fixedly installed in the frame 1; this ensures the stable installation of the rotating spindle 8 in the frame 1.

[0036] Furthermore, the heat-shrink tool mechanism 6 includes a second displacement mechanism 6.1 and a heater 6.2. The second displacement mechanism 6.1 drives the heater 6.2 to move. The heat-shrink tool holder 10 is installed on the upper end of the rotating spindle 8, and the heater 6.2 heats the rotating heat-shrink tool holder 10. The second displacement mechanism 6.1 can be used to drive the heater 6.2 to move to the upper end of the rotating spindle 8 to perform the heating action, thereby achieving stable heating of the heat-shrink tool holder 10 on the rotating spindle 8 and achieving the technical effect of heating and expanding to install the milling tool 12. The laser measurement mechanism 7 includes a first displacement mechanism 7.1 and a detection unit 7.2. The first displacement mechanism 7.1 drives the detection unit 7.2 to move, and the detection unit 7.2 performs laser detection on the rotating heat shrink tool holder 10. The first displacement mechanism 7.1 can be used to move the detection unit 7.2 to the heat shrink tool holder 10 after the milling cutter 12 is installed. As the rotating spindle 8 rotates, the heat shrink tool holder 10 can be driven to rotate. The detection unit 7.2 will perform laser detection on the rotating milling cutter 12 to realize the error judgment of rotation concentricity, thereby ensuring the installation accuracy of the milling cutter 12 in the heat shrink tool holder 10.

[0037] Furthermore: A rotary cylinder 15 is fixedly installed at the bottom end of the rotating main shaft 8. A movable rod 16 is connected inside the rotary cylinder 15.

A pull rod 21 is detachably installed at the top of the movable rod 16, and the top of the pull rod 21 is inserted into the conversion sleeve body 20 with a clearance fit. The ejector pin hole 13 is integrally formed in the movable rod 16 and the pull rod 21, and the ejector pin 9 can be adjusted to move up and down in the ejector pin hole 13. When the rotary cylinder 15 drives the movable rod 16 to move up and down, the upper end of the movable rod 16 will be inserted into the conversion sleeve body 20 through the pull rod 21. At this time, the conversion sleeve body 20 can be stably assembled into the conversion slot 18. The installation and locking of the conversion sleeve body 20 can be controlled by the operation of the rotary cylinder 15, which makes it convenient to replace conversion sleeve bodies 20 of different sizes, and thus suitable for use with heat shrink tool holders 10 of different hole diameters.

[0038] Furthermore: the movable rod 16 has an assembly groove 23 formed at one end near the conversion sleeve body 20, and a trapezoidal protrusion 24 is formed on the outer side of the bottom end of the pull rod 21. The trapezoidal protrusion 24 is inserted into the assembly groove 23 with a clearance fit. Several round holes 25 are formed on the outer side of the top end of the movable rod 16. The inner side of the round holes 25 passes through the assembly groove 23. Glass beads 26 are installed in the round holes 25 with a clearance fit. When the movable rod 16 moves downward, the glass beads 26 press against the trapezoidal protrusion 24. When the movable rod 16 moves upward, the glass beads 26 are in the clearance slot 19 with a clearance fit. When the rotary cylinder 15 drives the movable rod 16 to rise or fall, the mutual cooperation between the glass beads 26, the trapezoidal protrusion 24 and the clearance slot 19 can be used to realize the quick installation and removal of the pull rod 21 on the upper end of the movable rod 16, which can facilitate the replacement of conversion sleeve bodies 20 with different hole diameters for use.

[0039] Furthermore: at least two L-shaped buckles 27 are formed on the outer side of the upper end of the conversion sleeve body 20, and at least two buckles 28 are fixedly installed on the upper end surface of the rotating main shaft 8. When the conversion sleeve body 20 is pressed and rotated, the buckles 28 are inserted into the L-shaped buckles 27 with corresponding gaps. A spring 29 is installed between the upper end of the rotating main shaft 8 and the conversion sleeve body 20. The mutual cooperation between the L-shaped buckles 27 and the buckles 28, as well as the elastic stress of the spring 29, allows the conversion sleeve body 20 to be quickly installed and disassembled after being pressed and rotated. With the help of the rotary cylinder 15 driving the movable rod 16 to move up and down, the conversion sleeve body 20 can be quickly installed and disassembled, and the installation stability is higher.

[0040] Furthermore: the intelligent milling cutter cabinet 2 includes a cabinet body 2.1, a milling cutter bracket 2.2, a tool support plate 2.3, a lifting unit 2.4, and a pallet moving mechanism 2.5; The milling cutter bracket 2.2 is fixedly installed on the left side inside the cabinet 2.1.

The bottom pallet 32 ​​can lift one of the tool support plates 2.3 in the milling cutter bracket 2.2 and move it to the inside of the square slot 33. Then, the robot arm 11 takes away the corresponding milling cutter 12 to be installed on the tool support plate 2.3, realizing the effect of quick tool loading. The milling cutter cabinet can not only store various milling cutters 12, but also facilitate the selection and use of milling cutters 12.

[0041] Furthermore, the bottom support plate 32 lifts one of the tool support plates 2.3 through a lifting mechanism and moves it into the square groove 33, making the top surface of the tool support plate 2.3 flush with the top surface of the cabinet 2.1; it can lift the tool support plate 2.3 to a state where the tool support plate 2.3 and the cabinet 2.1 are flush, making the flatness of the entire cabinet 2.1 better and facilitating the removal of the tool from the tool support plate 2.3.

[0042] Furthermore: the tool holder conversion sleeve structure 3 includes a conveyor line 3.1 and several tool holder fixtures 3.2; The tool holder fixture 3.2 includes a base plate 3.21 and a positioning sleeve 3.22.

The rollers 36 slide on the arc-shaped track 35. The heat-shrink tool holders 10 are placed in several tool holder fixtures 3.2. The conveyor line 3.1 drives the tool holder fixtures 3.2 to move to the side of the robot arm 11. The robot arm 11 then performs the rapid installation and removal of the heat-shrink tool holders 10 on the rotating spindle 8 of the worktable 4, realizing the automatic loading and unloading of the heat-shrink tool holders 10. The positioning sleeve 3.22 has a slot for placing and installing the heat-shrink tool holders 10, which can ensure the precise positioning of the heat-shrink tool holders 10. The bottom side of the base plate 3.21 slides stably on the arc track 35 of the conveyor line 3.1 through the roller 36, thereby ensuring the stable transport of the entire tool holder fixture 3.2. When the robot arm 11 removes the heat-shrink tool holders 10, the tool holder fixtures 3.2 will not separate from the arc track 35.

When the milling cutter 12 needs to be taken out, the lifting unit 2.4 and the pallet moving mechanism 2.5 drive the bottom pallet 32 ​​to lift the tool support plate 2.3 at the corresponding position of the milling cutter 12 and transport it to the inside of the square slot 33, so as to facilitate the removal of the corresponding milling cutter for use.

[0063] Furthermore: the bottom support plate 32 drives one of the tool support plates 2.3 to move into the square groove 33, so that the top surface of the tool support plate 2.3 is flush with the top surface of the cabinet 2.1; the bottom support plate 32 can be driven by the lifting unit 2.4 and the pallet moving mechanism 2.5 to realize the automatic replacement of the lifted tool support plate 2.3, realize the loading and unloading of milling cutters of different sizes in the square groove 33, which is convenient for actual use. When lifting the tool support plate 2.3, it can pass through the square groove 33 and be flush with the upper surface of the cabinet 2.1, thus facilitating the loading and unloading of the milling cutter 12.

[0064] Furthermore, the tool support plate 2.3 is formed with a plurality of milling cutter mounting holes 64 evenly arranged; the milling cutter 12 can be placed in the milling cutter mounting holes 64 to prevent the milling cutter 12 from shifting and falling off, thereby ensuring the stable placement and removal of the milling cutter 12.

The two vertical optical shafts 2.43 are fixedly installed inside the cabinet 2.1. Through holes 65 are formed at both the front and rear ends of the right side of the lifting frame 2.41. The vertical optical shafts 2.43 are slidably fitted into the through holes 65. This allows for stable lifting and lowering of the lifting frame 2.41, enabling the base plate 32 to stably support the corresponding tool support plate 2.3 and move it into the square slot 33, facilitating the loading and unloading of the milling tool 12.

[0066] Furthermore, the lifting frame 2.41 has transverse slots 66 formed on both the front and rear sides, and the front and rear edges of the base plate 32 are slidably fitted into the transverse slots 66 respectively; the transverse slots 66 can ensure the stable movement of the base plate 32 within the lifting frame 2.41.

[0067] Furthermore, a slide rail 67 is installed between the front and rear sides of the base plate 32 and the transverse slot 66; the slide rail 67 can be a drawer slide rail 67, which has higher sliding stability.

[0068] Furthermore, rubber pillars 68 are fixedly installed at all four ends of the upper surface of the base plate 32.

When needed, it can be pulled up from the side, which is convenient for actual operation.

[0070] Furthermore, the width of the movable slot 70 is greater than the thickness of the tool support plate 2.3; the corresponding tool support plate 2.3 can be raised first using the base plate 32 so that the front and rear sides of the tool support plate 2.3 do not contact the movable slot 70. Then, the tool support plate 2.3 can be pulled out from the side and raised to the inside of the square slot 33, which can reduce the resistance of the tool support plate 2.3 movement, make its conveying stability higher, and ensure its service life.
