Description

Technical Field

[0001] The present invention relates to the technical field of machine tool accessories, and more specifically, it relates to a deburring device for extra-long bolts. Background Art

[0002] Currently, for the existing technology of deburring extra-long bolts, a chuck fixture is usually used to clamp the bolt to keep it stationary, and a cylinder is used to push the bolt to approach a cutting blade (a sleeve with spiral cutting edges on the inner wall) rotating at high speed at a uniform speed. The rotation center of the chuck fixture is coaxial with the rotation center of the high-speed rotating cutting blade to ensure the coaxiality of the bolt and the cutting blade. Then, the inner wall of the cutting blade is used to process the threads of the bolt. This technology can achieve the removal of burrs on extra-long bolts and is widely used in related production fields, but there are still certain defects: During the process of the bolt approaching the high-speed rotating cutting blade and the deburring operation, the coaxiality between the bolt and the cutting blade depends on the coaxiality between the rotation center of the chuck fixture and the rotation center of the cutting blade. In actual operation, to make the rotation axis of the chuck fixture and the rotation axis of the cutting blade achieve high-precision coaxiality, the installation and debugging process is extremely complex and time-consuming, and the accuracy may decrease due to wear, affecting the coaxiality. Furthermore, there are no effective measures to ensure that the bolt and the cutting blade always remain coaxial.

[0003] Once the coaxiality deviates, the contact pressure between the inner wall of the cutting blade and the thread surface of the bolt will be unevenly distributed. In the area with a large coaxiality deviation, the contact pressure between the deburring component and the thread surface may be too large, resulting in excessive removal of burrs in this area and even possible damage to the thread itself (such as: changing the thread profile angle, resulting in uneven gaps during thread fitting), affecting the strength and accuracy of the bolt; while in the area with a small coaxiality deviation or reverse deviation, the contact pressure is insufficient, making it impossible to completely remove the burrs, resulting in partial burr residues. This uneven deburring effect seriously affects the surface quality of the bolt threads and makes it difficult to meet the requirements of high-precision assembly.

[0004] Therefore, how to achieve efficient and precise deburring treatment for extra-long bolts has become an urgent technical problem in this field. Summary of the Invention

[0027] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed so that those skilled in the art can better understand and thus implement the subject matter described herein. Changes can be made to the functions and arrangements of the elements discussed without departing from the scope of protection of the content of this specification. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0028] Refer to Figure 1 , Figure 2 and Figure 3, in this embodiment, a deburring device for ultra-long bolts is proposed, which includes a machine body 1 and a stepping feeding unit 2 located at the rear side of the machine body 1 for feeding bolts 3. The stepping feeding unit 2 includes a feeding component 21 and an adaptive component 22 located in front of the feeding component 21. A driving part 13 and a support plate 8 are fixedly installed on the top of the machine body 1 through a mounting seat 4. A cylinder 10 is fixedly installed on the right side of the support plate 8. A cutting blade 12 for deburring the thread of the bolt 3 is fixedly installed at the output end of the driving part 13. Two symmetrically arranged guide rods 9 are commonly installed between the support plate 8 and the driving part 13. A clamping part 7, a locking part 6, and a guiding part 5 are sequentially arranged on the outer side of the guide rod 9 from right to left.

[0029] Refer to Figure 1 , Figure 2 and Figure 3 , the guiding part 5 includes a guiding component 51 for first clamping the top bolt 3 that falls on the top of the adaptive component 22 and limiting the bolt 3 in the circumferential and front-back directions as it moves leftward with the clamping part 7, and a control component 52 for controlling the guiding component 51. The locking part 6 includes a locking component 61 for horizontally penetrating the guiding component 51 and the adaptive component 22 after moving leftward with the clamping part 7 and guiding the bolt 3 by the guiding component 51, and integrally coaxially locking the guiding component 51, the adaptive component 22, and the cutting blade 12.

[0030] Refer to Figure 3 and Figure 4 , the adaptive component 22 includes two loading racks 221 fixedly installed in front of the feeding component 21. A slide rail 222 is fixedly installed on the front side of the right loading rack 221. An adjusting bracket 223 is slidably installed on the front side of the slide rail 222. The adjusting bracket 223 and the left loading rack 221 are jointly used to support the bolt 3. A strong spring (not shown in the figure) is arranged between the adjusting bracket 223 and the right inner wall of the slide rail 222, and the strong spring is used to pull the adjusting bracket 223 close to the right inner wall of the slide rail 222.

[0031] It should be noted that the driving part 13 is selected as a servo motor, and the rotation speed can be adjusted according to the size and quantity of the burrs. If the burrs are large and numerous, a higher rotation speed and power (1500 - 2500 r / min) are required to remove them quickly and effectively; if the burrs are small and few, a lower rotation speed (1000 - 1500 r / min) can be selected. The above-mentioned feeding component 21 is common knowledge for those skilled in the art, so it will not be elaborated in this application.

[0032] During specific use, the feeding component 21 conveys the bolt 3 to the tops of the two loading racks 221, and then the bolt 3 slides forward along the top surfaces of the loading racks 221 and falls on the top of the adjusting bracket 223, realizing the preliminary positioning and support of the bolt 3 and ensuring the coaxiality of the bolt 3 and the cutting blade 12.

[0033] Refer to Figure 4 、 Figure 5 and Figure 6 wherein the clamping portion 7 includes a driving frame 71 fixedly installed at the output end of the cylinder 10 and slidably connected to two guide rods 9. A pushing assembly 62 for horizontally moving the locking assembly 61 is arranged between the locking assembly 61 and the clamping portion 7. After the pushing assembly 62 pushes the locking assembly 61 to lock the guiding assembly 51, the adaptive assembly 22 and the cutting blade 12, the clamping portion 7 contacts and presses the end of the bolt 3 to clamp the end of the bolt 3, and finally pushes the bolt 3 and the adaptive portion to move closer to the cutting blade 12 for deburring operation of the bolt 3.

[0034] Refer to Figure 4 、 Figure 5 and Figure 6 The pushing assembly 62 includes two mounting rods 621 fixedly installed on the left side of the driving frame 71 and symmetrically arranged front and back. A push plate 622 for pushing the reset plate 611 is jointly installed at the left ends of the two mounting rods 621. The locking assembly 61 includes two fixing plates 614 fixedly installed at the bottom of the left loading rack 221 and symmetrically arranged front and back, and respectively fixedly sleeved outside the two guide rods 9. A first reset spring 613 sleeved outside the corresponding guide rod 9 is fixedly installed on the right side of the fixing plate 614. The right ends of the two first reset springs 613 are jointly installed with a reset plate 611, and the reset plate 611 is slidably installed outside the two guide rods 9.

[0035] During specific use, after the bolt 3 falls on the top of the adjustment bracket 223, the cylinder 10 is started to push the driving frame 71 to move leftward along the guide rod 9. As the driving frame 71 moves leftward, it will drive the clamping portion 7 to gradually approach the end of the bolt 3. At the same time, the push plate 622 gradually approaches and contacts the reset plate 611, and then pushes the reset plate 611 to move leftward.

[0036] Refer to Figure 5 、 Figure 8 and Figure 9 The guiding assembly 51 includes a mounting frame 511 fixedly installed at the bottom of the left loading rack 221. Two rotating shafts 512 are rotatably installed on the left side of the mounting frame 511 and symmetrically arranged front and back. The left ends of the rotating shafts 512 penetrate through the mounting frame 511 and are fixedly installed with connecting frames 513. The two connecting frames 513 are symmetrical to each other, and guiding plates 514 are fixedly installed on the closer sides of the two connecting frames 513. A number of rolling balls are rotatably installed on the inner walls of the guiding plates 514. The rolling balls contact the bolt 3 when the guiding plates 514 clamp the bolt 3 to limit the bolt 3 in the circumferential and front-back directions while not hindering the left-right movement of the bolt 3.

[0037] It should be noted that the guiding plate 514 is an arc-shaped plate (the radius of curvature matches the rod portion of the bolt), and 9 rolling balls are evenly distributed on the inner wall to form a rolling friction pair.

[0038] Refer to Figure 5 、 Figure 8 and Figure 9 As shown in, the control component 52 includes a gear 523 fixedly sleeved outside the rotating shaft 512. A rack 522 is meshed between two gears 523. The rack 522 is slidably connected to a chute opened on the right inner wall of the mounting frame 511 through a slider. A thrust spring (not shown in the figure) is arranged between the rack 522 and the right inner wall of the mounting frame 511 to push the rack 522 downward so that the slider abuts against the bottom wall of the chute, driving the rack 522 to drive the gear 523 to control the guide plate 514 to clamp the bolt 3.

[0039] Refer to Figure 5 、 Figure 8 and Figure 9 As shown in, a control rod 521 is fixedly installed at the bottom of the rack 522. A trapezoidal plate 524 matched with the control rod 521 is fixedly installed on the left side of the reset plate 611 through a fixed rod. The right slope of the trapezoidal plate 524 is used to reset and press the control rod 521 along with the locking component 61 after the deburring operation is completed, driving the guiding component 51 to release the clamping of the bolt 3.

[0040] During specific use, during the process of the reset plate 611 being pushed leftward by the push plate 622, first, the trapezoidal plate 524 gradually disengages from the control rod 521. As the trapezoidal plate 524 disengages from the control rod 521, the rack 522 moves downward under the action of the thrust spring, and the gear 523 drives the rotating shaft 512 to rotate, driving the tops of the two connecting frames 513 to approach each other, so that the two guide plates 514 rotate and close synchronously toward the side close to the bolt 3 until the balls on the inner wall of the guide plate 514 contact the rod part of the bolt 3. Since the balls can rotate freely, rolling friction is formed during contact, which can not only perform circumferential limit (limit rotation) and front-back direction limit (limit radial swing) on the bolt 3, but also allow the bolt 3 to slide axially (left-right direction), avoiding hindering the feeding of the subsequent deburring operation due to rigid clamping.

[0041] Refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 8 As shown in, the locking component 61 further includes two locking pins 612 fixedly installed on the left side of the reset plate 611 and symmetrically arranged front and back. A locking sleeve 616 sleeved outside the cutting blade 12 is fixedly installed on the right side of the driving member 13. The locking sleeve 616 and the cutting blade 12 are connected through a bearing. Pin holes 615 are opened on the locking sleeve 616, the connecting frame 513, and the left loading rack 221. The number of pin holes 615 on the loading rack 221 and the locking sleeve 616 is two, and the pin holes 615 on the same side correspond to each other.

[0042] During specific use, the reset plate 611 will also drive the locking pin 612 to move synchronously during the moving process. As the reset plate 611 continues to move leftward, after the guiding plate 514 closes and clamps the bolt 3, when the reset plate 611 continues to drive the two locking pins 612 to move leftward, the locking pins 612 will sequentially penetrate the corresponding pin holes 615 on the left loading rack 221, the connecting rack 513, and the locking sleeve 616 from right to left. While rigidly locking the guiding assembly 51, the cutting blade 12, the guiding assembly 51, and the left loading rack 221 are integrally coaxially locked, eliminating the position deviation (such as machining error, assembly clearance, wear after long-term use, etc.) when the cutting blade 12 and the loading rack 221 are independently installed, ensuring that the axis of the cutting blade 12 is strictly coaxial with the axis of the bolt 3, achieving the effect of one-time insertion and automatic calibration, thereby greatly improving the coaxiality between the cutting blade 12 and the bolt 3, and forming a rigid force transmission path starting from the bolt 3, passing through the guiding plate 514, the connecting rack 513, the locking pin 612, the locking sleeve 616 in sequence, and finally transmitting to the cutting blade 12, eliminating the radial clearance, and avoiding uneven thread cutting of the bolt 3 by the cutting blade 12 during high-speed rotation due to axis offset, resulting in burr residue or thread damage, and significantly improving the deburring accuracy.

[0043] Refer to Figure 6 and Figure 7 , the clamping portion 7 further includes a mounting plate 72 fixedly installed on the inner wall of the driving frame 71. A plurality of claws 73 for clamping the end of the bolt 3 are hinged on the left side of the mounting plate 72. An articulated sleeve 74 is commonly hinged between the plurality of claws 73. A reset rod 75 for abutting against the end of the bolt 3 is fixedly installed on the inner wall of the articulated sleeve 74. The right end of the reset rod 75 slidably penetrates the mounting plate 72 and is fixedly installed with a circular plate 77. A second reset spring 76 sleeved on the outside of the reset rod 75 is commonly installed between the circular plate 77 and the mounting plate 72.

[0044] It should be noted that the elastic coefficient of the strong spring is greater than that of the second reset spring 76. The number of claws 73 is 3, and anti-slip tooth patterns are processed on the inner side.

[0045] When the locking pin 75 is in the unlocking state, the locking pin 77 is in the unlocking state, and the locking pin 77 is in the unlocking state.

[0046] Next, the cutting blade 12 is driven to rotate at high speed through the driving member 13, and at the same time, the driving frame 71 continues to push the clamped, limited guided and coaxially corrected bolt 3 to move to the left to contact the high-speed rotating cutting blade 12, and then gradually extends into the interior of the cutting blade 12 to deburr the entire external thread of the bolt 3.

[0047] It should be noted that the length of the cutting blade 12 is greater than the length of the bolt 3, and the inner wall of the cutting blade 12 is processed with a spiral cutting edge (the cutting edge angle is 30°-60°, and the pitch is consistent with the thread of the bolt 3) that is opposite to the thread of the bolt 3. The cutting blade 12 is rotated to shear and cut the thread surface of the bolt 3 to remove burrs.

[0048] See also Figure 1 and Figure 2 A material unloading rack 11 is fixedly mounted on the top of the machine body 1 and is located in front of the mounting seat 4 and is used to cooperate with the external material unloading assembly.

[0049] During specific use, after the deburring operation is completed, the output end of the control cylinder 10 contracts, driving the drive plate to move to the right for resetting. During the entire resetting process, the strong spring is first gradually reset, driving the adjusting bracket 223 to move to the right, thereby driving the processed bolt 3 to move to the right for discharging. When the bolt 3 is completely pulled out of the cutting blade 12, the reset plate 611 continues to reset and will first gradually drive the locking pin 612 to be pulled out from the pin hole 615, releasing the lock between the cutting blade 12, the bolt 3 and the left side support frame, and then drive the right slope of the trapezoidal plate 524 to squeeze the control rod 521, drive the control rod 521 to push the rack 522 to move up and drive the gear 523 to rotate, thereby driving the left end of the rotating shaft 512, and then driving the two connecting frames 513 to move away from the bolt 3, releasing the clamping of the bolt 3, and finally, the bolt 3 that has completed the deburring operation is transferred to the top of the unloading frame 11 for unloading through the external unloading assembly.

[0050] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
