Description

Technical Field

[0001] This invention belongs to the field of long shaft parts processing technology, and more specifically, relates to an anti-vibration device for processing long shaft parts. Background Technology

[0002] Long shaft parts are prone to wobbling during machining due to cutting forces, their own weight, and centrifugal forces generated by rotation. This not only reduces machining accuracy such as cylindricity and surface roughness, but also exacerbates tool wear and affects subsequent assembly and equipment operation stability. Therefore, anti-wobbling devices are needed to position the right end of long shaft parts to avoid these problems.

[0003] The anti-runaway devices currently in use for long shaft parts still have the following problems: 1. The anti-runaway device is generally connected to the machine tool by bolts, which cannot tighten and limit the mounting screws, causing the anti-runaway device to wobble after long-term use; 2. When processing long shaft parts of different sizes, the operator needs to readjust the positioning position, resulting in poor versatility; 3. The anti-runaway positioning head on the anti-runaway device cannot accurately follow the rotation of the long shaft part, increasing wear. Summary of the Invention

[0004] This disclosure relates to an anti-jump device for machining long shaft parts, comprising an installation positioning unit, a part anti-jump unit, an auxiliary connecting unit, an elastic driving unit, and a protective pushing unit. The movable limit frame automatically presses against the four mounting screws on the installation positioning seat, ensuring the installation positioning seat remains stable after installation. It is adaptable to machining long shaft parts of different sizes, offering greater versatility. The left end of a ring of auxiliary connecting rods contacts the right end face of the long shaft part, ensuring the anti-jump head continuously and accurately follows the rotation of the long shaft part. This solves the problems of insufficient pressure on the mounting screws, the need for workers to readjust the positioning position when machining long shaft parts of different sizes, and the inability of the anti-jump positioning head on the anti-jump device to accurately follow the rotation of the long shaft part.

When the inner ends of the two threaded limiting pins 104 are inserted into the two circular limiting slots 1011 above, the irregularly shaped baffle 103 on the right side covers the control button on the intelligent controller 600, which helps to prompt the staff to move the position of the movable limit frame 102. When the inner ends of the two threaded limiting pins 104 are inserted into the two circular limiting slots 1011 below, the irregularly shaped baffle 103 on the right side no longer covers the control button on the intelligent controller 600, and the movable limit frame 102 automatically presses the four mounting screws on the mounting positioning seat 101, so that the mounting positioning seat 101 can always be in a stable state after installation.

[0044] In this embodiment of the disclosure, such as Figure 3 , Figure 6 and Figure 7 As shown, the anti-jump unit 200 includes: a rectangular guide rod 201 and an anti-jump seat 202; there are two rectangular guide rods 201, and the two rectangular guide rods 201 are slidably mounted on the mounting positioning seat 101; the anti-jump seat 202 is fixedly mounted on the left side of the two rectangular guide rods 201; the anti-jump unit 200 also includes: a connecting bearing 203 and an anti-jump head 204; the connecting bearing 203 is mounted on the anti-jump seat 202; the anti-jump head 204 is mounted on the connecting bearing 203.

[0046] The specific functions of the anti-jump unit 200 and the elastic drive unit 400 are as follows: Because the connecting bearing 203 is installed on the anti-jump seat 202 and the anti-jump head 204 is installed on the connecting bearing 203, the anti-jump head 204 can rotate simultaneously with the long shaft part, reducing the wear of the anti-jump head 204; because the anti-jump seat 202 is slidably connected to the output shaft of the electric telescopic rod 401, and the helical spring b404 is sleeved on the outside of the output shaft of the electric telescopic rod 401, and the helical spring b404 is located between the anti-jump seat 202 and the L-shaped limit plate 403, when the anti-jump head 204 contacts the long shaft part, the anti-jump head 204 will stop moving, and the output shaft of the electric telescopic rod 401 will continue to extend. When the L-shaped limit plate 403 presses the control button 405, the intelligent controller 600 controls the electric telescopic rod 401 to stop working, which is suitable for processing long shaft parts of different sizes and has stronger versatility.

[0047] In this embodiment of the disclosure, such as Figure 5 , Figures 8 to 10 As shown, the auxiliary connection unit 300 includes: a movable mounting ring 301, a helical spring a302, and an auxiliary connecting rod 303; the movable mounting ring 301 is slidably mounted on the anti-jump head 204; the helical spring a302 has one coil, and both ends of the coil a302 are fixedly connected to the anti-jump head 204 and the movable mounting ring 301; the auxiliary connecting rod 303 has one coil, and the auxiliary connecting rod 303 is fixedly mounted on the left side of the movable mounting ring 301, and the left end of the auxiliary connecting rod 303 has a tapered structure.

[0048] The protective push unit 500 includes: a movable protective frame 501, a rectangular anti-slip plate 502, and an adjusting screw 503; the movable protective frame 501 is slidably mounted on the mounting positioning seat 101; two rectangular anti-slip plates 502 are provided, and the two rectangular anti-slip plates 502 are fixedly mounted on the bottom of the movable protective frame 501, and the two rectangular anti-slip plates 502 are located directly above the two rectangular guide rods 201; the bottom end of the adjusting screw 503 is rotatably mounted on the mounting positioning seat 101, and the adjusting screw 503 is also threadedly connected to the movable protective frame 501; the protective push unit 500 also includes: The system includes a guide frame 504, a movable mounting plate 505, and a circular connecting rod 506. The guide frame 504 is fixedly installed on the left side of the movable protective frame 501. The movable mounting plate 505 is slidably installed on the guide frame 504. The circular connecting rod 506 is fixedly installed on the top of the anti-jump seat 202 and is also slidably connected to the movable mounting plate 505. The protective push unit 500 also includes a rectangular vertical plate 507 and a push ball 508. The rectangular vertical plate 507 is fixedly installed on the movable mounting plate 505. The push ball 508 is rotatably installed on the rectangular vertical plate 507.

[0049] The specific functions of the auxiliary connection unit 300 and the protective push unit 500 are as follows: The movable protective frame 501 is slidably mounted on the mounting positioning seat 101, and the bottom end of the adjusting screw 503 is rotatably mounted on the mounting positioning seat 101. Furthermore, the adjusting screw 503 is threadedly connected to the movable protective frame 501. When the operator rotates the adjusting screw 503 with a wrench, the movable protective frame 501 causes the two rectangular anti-slip plates 502 to move downwards, making the bottom of the two rectangular anti-slip plates 502 contact the two rectangular guide rods 201. This protects the electric telescopic rod 401, preventing cutting forces and centrifugal forces from... The action on the output shaft of the electric telescopic rod 401 improves the service life of the electric telescopic rod 401; and because the movable mounting plate 505 is slidably mounted on the guide frame 504, and the circular connecting rod 506 is fixedly mounted on the top of the anti-jump seat 202, and the circular connecting rod 506 is also slidably connected to the movable mounting plate 505, when the output shaft of the electric telescopic rod 401 extends, the anti-jump seat 202 and the circular connecting rod 506 drive the movable mounting plate 505 to move to the left; when the operator turns the adjusting screw 503 with a wrench, the guide frame 504 drives the movable mounting plate 505 to move downward.

[0050] Furthermore, because the movable mounting ring 301 is slidably mounted on the anti-jump head 204 of the part, and an auxiliary connecting rod 303 is fixedly mounted on the left side of the movable mounting ring 301, and pushes the ball 508 to rotate and is mounted on the rectangular vertical plate 507, when the operator turns the adjusting screw 503 with a wrench, the ball 508 can push the movable mounting ring 301 to slide to the left a certain distance, so that the left end of the auxiliary connecting rod 303 contacts the right end face of the long shaft part, ensuring that the anti-jump head 204 follows the long shaft part to rotate continuously and accurately; and because the two ends of the coil spring a302 are fixedly connected to the anti-jump head 204 of the part and the movable mounting ring 301, when the movable protective frame 501 is reset upward under the action of the adjusting screw 503, the movable mounting ring 301 is automatically reset to the right under the action of the coil spring a302, ensuring that when the long shaft part is positioned next time, the anti-jump head 204 first contacts the positioning hole on the long shaft part.

[0051] The specific usage and function of this embodiment are as follows:

[0052] When using this invention, firstly, the mounting positioning seat 101 is installed in a suitable position on the machine tool using bolts to ensure that the anti-jump head 204 of the part is concentric with the clamped long shaft part. Then, the two threaded limiting pins 104 are loosened, and then the movable limiting frame 102 is slid down so that the inner ends of the two threaded limiting pins 104 are inserted into the two circular limiting grooves 1011 below. At this time, the irregularly shaped baffle 103 on the right side no longer blocks the control button on the intelligent controller 600, and the movable limiting frame 102 automatically presses the four mounting screws on the mounting positioning seat 101 so that the mounting positioning seat 101 can always be in a stable state after installation.

[0053] The output shaft of the electric telescopic rod 401 extends as controlled by the control button on the intelligent controller 600. When the anti-jump head 204 of the part contacts the long shaft part, the anti-jump head 204 stops moving, and the output shaft of the electric telescopic rod 401 continues to extend. When the L-shaped limit plate 403 presses the control button 405, the intelligent controller 600 controls the electric telescopic rod 401 to stop working. It is suitable for processing long shaft parts of different sizes and has stronger versatility. When the output shaft of the electric telescopic rod 401 extends, the anti-jump seat 202 of the part and the circular connecting rod 506 drive the movable mounting plate 505 to move to the left.

[0054] When the operator turns the adjusting screw 503 with a wrench, the movable protective frame 501 moves the two rectangular anti-slip plates 502 downwards, so that the bottom of the two rectangular anti-slip plates 502 contacts the two rectangular guide rods 201, which protects the electric telescopic rod 401 and prevents cutting force and centrifugal force from acting on the output shaft of the electric telescopic rod 401, thus improving the service life of the electric telescopic rod 401. When the operator turns the adjusting screw 503 with a wrench, the guide frame 504 moves the movable mounting plate 505 downwards. At the same time, the pushing ball 508 pushes the movable mounting ring 301 to slide to the left a certain distance, so that the left end of the auxiliary connecting rod 303 contacts the right end face of the long shaft part, ensuring that the anti-jump head 204 of the part continues to rotate accurately with the long shaft part.

[0055] After use, turn the adjusting screw 503 in the opposite direction with a wrench to reset the movable protective frame 501 upwards, and then retract the output shaft of the electric telescopic rod 401 by using the control button on the intelligent controller 600.
