Description

Technical Field

[0001] This utility model relates to the field of flexible shaft processing technology, and in particular to a fixed-length melting mechanism. Background Technology

[0002] Flexible shafts are shafts with low rigidity and high elasticity, capable of free bending and transmission. They are used to connect two shafts that are not on the same axis, not in the same direction, or have relative motion to transmit rotational motion and torque, flexibly transmitting rotational motion and torque to any position. During processing, flexible shafts often require fusing. Typically, the flexible shaft is fed to a predetermined length and then broken into the required length using high temperature. However, different specifications of flexible shafts have different lengths, requiring manual adjustment of the feeding stroke. Furthermore, the feeding process is subject to certain errors, making it difficult to ensure the flexible shaft reaches the predetermined length. This leads to deviations in the fusing operation's execution position, resulting in poor applicability and directly affecting the final product's dimensions and quality. Utility Model Content

The limiting plate is telescopically mounted on the mounting part. The elastic element is located between the mounting part and the limiting plate.

[0018] 1. This utility model provides a fixed-length fusing mechanism, which can adjust the distance between the clamping mechanism and the fusing component according to the predetermined length of the flexible shaft. During the feeding process of the flexible shaft, the material transfer jaws open to allow the flexible shaft to be inserted between two pressure blocks. The end of the flexible shaft abuts against the limiting plate. The limiting plate is pressed and moves closer to the mounting part as the flexible shaft is inserted. When the flexible shaft is fed to the predetermined length, the limiting plate abuts against the trigger part of the micro switch to trigger the micro switch. The lifting drive device drives the fusing head to descend so that it fuses the flexible shaft with the fusing table, thereby effectively improving the accuracy and applicability of the fusing operation and ultimately improving product quality.

[0019] 2. After the flexible shaft is melted, the material transfer jaws drive the two pressure blocks to clamp the flexible shaft. This design ensures that the flexible shaft is tightly clamped in place, avoiding loosening due to insufficient clamping force, thus ensuring that the subsequent melting operation can proceed normally, thereby improving processing efficiency and product quality.

The fusing assembly 20 includes a frame 201, a lifting drive device 202, and fusing platforms 203 and fusing heads 204 arranged opposite to each other. The fusing platform 203 is fixedly connected to the frame 201. The lifting drive device 202 is disposed on the frame 201 and is a telescopic cylinder or an electric push rod. The lifting end of the lifting drive device 202 is connected to the fusing head 204. Preferably, a guide mechanism 21 for guiding the translation of the flexible shaft 1 is provided at a position between the frame 201 and the fusing head 204. The guide mechanism 21 can be a pneumatic gripper or a sleeve, and the guide mechanism 21 has a gap for the fusing head 204 to pass through.

[0029] A translation drive device 3 is provided on the base 2. The translation drive device 3 can be an electric slide table. The translation end of the translation drive device 3 is provided with a mounting frame 4. The translation drive device 3 adjusts the position of the mounting frame 4 in the length direction of the base 2. The material transfer assembly 5 is provided on the mounting frame 4. The material transfer assembly 5 is provided with a mounting plate 6 at its material transfer end. The material transfer assembly 5 includes a first translation mechanism 51 and a second translation mechanism 52. The first translation mechanism 51 is provided on the top of the mounting frame 4. The first translation mechanism 51 and the second translation mechanism 52 can be telescopic cylinders or electric push rods. The translation end of the first translation mechanism 51 is connected to the second translation mechanism 52. The first translation mechanism 51 adjusts the position of the second translation mechanism 52 in the longitudinal direction. The translation end of the second translation mechanism 52 is connected to the mounting plate 6. The second translation mechanism 52 adjusts the position of the mounting plate 6 in the vertical direction, so that the material transfer assembly 5 moves the position of the mounting plate 6 in the vertical and longitudinal directions.

[0030] The clamping mechanism 7 includes a material transfer gripper 71, a mounting part 72, a limiting plate 73, two elastic elements 74 and a micro switch 75. The material transfer gripper 71 is a pneumatic gripper and is mounted on the mounting plate 6. The clamping end of the material transfer gripper 71 is provided with a pressure block 8, which has an L-shaped structure.

[0031] The gap between the two pressure blocks 8 forms a clamping space 9 for clamping the flexible shaft 1. The mounting part 72 is located below the material transfer gripper 71 and corresponds to the clamping space 9. The limiting plate 73 is telescopically mounted on the mounting part 72. The end face of the mounting part 72 has two symmetrically arranged movable slots 12. The elastic element 74 is a spring structure. The elastic element 74 is inserted into the movable slot 12, so that the elastic element 74 is located between the mounting part 72 and the limiting plate 73, so that the limiting plate 73 tends to move closer to the pressure block 8. The micro switch 75 is located on the top of the mounting part 72. The trigger part of the micro switch 75 is opposite to the limiting plate 73. The micro switch 75 is electrically connected to the lifting drive device 202.

[0032] The fixed-length fusing mechanism can adjust the distance between the clamping mechanism 7 and the fusing assembly 20 according to the predetermined length of the flexible shaft 1. During the feeding process of the flexible shaft 1, the material transfer jaw 71 opens to allow the flexible shaft 1 to be inserted between the two pressure blocks 8. The end of the flexible shaft 1 abuts against the limiting plate 73. The limiting plate 73 is pressed and moved closer to the mounting part 72 as the flexible shaft 1 is inserted. When the flexible shaft 1 is fed to the predetermined length, the limiting plate 73 abuts against the trigger part of the micro switch 75 to trigger the micro switch 75. At this time, the fusing position of the flexible shaft 1 corresponds to the fusing head 204. The lifting drive device 202 drives the fusing head 204 to descend so that it and the fusing table 203 fuse the flexible shaft 1, thereby effectively improving the accuracy and applicability of the fusing operation and ultimately improving product quality.

[0033] After the flexible shaft 1 melts, the transfer gripper 71 drives the two pressure blocks 8 to clamp the melted flexible shaft 1. This design ensures that the flexible shaft 1 is tightly clamped in place, avoiding loosening due to insufficient clamping force. The transfer assembly 5 adjusts the transfer gripper 71 vertically and longitudinally to send the melted flexible shaft 1 to the next station.

The sealing block 13 has a mating part 15 that mates with the mating groove 14. The mating part 15 and the mating groove 14 are fixedly connected by bolts to facilitate the installation and removal of the limiting plate 73. The sliding plate 10 has a through travel groove 16 extending along the length of the sliding groove 11. A travel member 17 is detachably connected between the sliding groove 11 and the sealing block 13. The travel member 17 is a bolt structure, with its rod portion passing through the travel groove 16 and threadedly connected to the inner wall of the sliding groove 11. The travel member 17 is slidably connected to the travel groove 16. The travel member 17 and the travel groove 16 cooperate to limit and guide the sliding between the slide plate 10 and the slide groove 11.

[0035] Preferably, the mounting bracket 4 is provided with a sensing part 18, and the base 2 is provided with at least one sensing device 19 along its length direction. The sensing part 18 and the sensing device 19 are in sensing cooperation. The sensing part 18 can be a metal sensing part, and the sensing device 19 can be a metal sensor. The sensing device 19 is electrically connected to the translation drive device 3 to detect whether the installation has reached the target position, so as to preset the distance between the clamping mechanism 7 and the fuse assembly 20.
