Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, and more specifically to a spindle polishing device. Background Technology

[0002] As a core component of spinning and winding in textile machinery, the polishing precision of the inner wall of the hollow tube and the outer wall of the spindle directly determines the yarn forming quality and the lifespan of the equipment. Currently, the industry generally uses manual operation for spindle polishing. The specific process is as follows: the operator manually inserts a flexible polishing rope into the hollow tube of the spindle and controls the up-and-down movement and rotation of the polishing rope with a hand tool to achieve inner wall polishing. The uneven lifting speed and rotation frequency of the polishing rope controlled manually can easily cause uneven polishing or excessive wear of the inner wall, affecting the dimensional accuracy of the spindle. Therefore, we propose a spindle polishing device. Summary of the Invention

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] See attached document Figure 1-6 A spindle polishing device is disclosed, wherein the spindle mainly consists of a spindle rod and two spindle arms, as well as a pressure plate connected to one of the spindle arms. Roving passes through the spindle rod and one of the hollow spindle arms and is guided to the yarn tube by the pressure plate. The device primarily polishes the inner wall of the hollow tube of the spindle and the outer walls of the two spindle arms. The pressure plate needs to be removed before use. The device includes a frame 1, a mounting plate 11 and a curved-straight composite slide rail 12 disposed within the frame 1. Adjacent end faces of the mounting plate 11 are provided with an active wheel 2 and a drive unit that cooperates with and drives the active wheel 2. The inner wall is provided with a mounting platform 3 via a bracket and a bearing. The mounting platform 3 and the drive wheel 2 are rotatably engaged. The drive unit includes a drive shaft 41 mounted on the mounting plate 11 via a bearing. One end of the drive shaft 41 is provided with a drive bevel tooth 4 that meshes with a passive bevel tooth 25 on the drive wheel 2. The other end is provided with a drive gear 42. The drive gear 42 meshes with a gear on the output end of a motor mounted in the frame 1 to form a drive. That is, the motor drives the drive gear 42 to rotate around the drive shaft 41 as the axis by meshing with the gear.

[0032] The active wheel 2 includes a platform shaft 24 mounted on the mounting plate 11 via bearings, and passive conical teeth 25 and a platform 21 mounted at both ends of the platform shaft 24. The passive conical teeth 25 mesh with the active conical teeth 4, causing the platform 21 to rotate around the platform shaft 24. An offset arc groove disk 22 and a toggle shaft 23 are also mounted on the platform 21 to control the rotation of the mounting platform 3.

[0033] The offset arc groove disk 22 is coaxially arranged with the platform 21, and the actuating shaft 23 is located at the edge of the platform 21 and corresponds to the offset arc of the offset arc groove disk 22;

[0034] The mounting platform 3 includes a mounting shaft 31, and mounting tables 3 and mounting turntables 32 mounted at both ends of the mounting shaft 31. The surface of the mounting platform 3 has through holes and a retainer for mounting the spindle blade. The spindle rod on the spindle blade can be inserted into the through hole, causing the spindle blade to be in an inverted state. This is existing technology and will not be described in detail. The mounting turntable 32 has at least one pair of arc-shaped grooves and strip-shaped grooves on its circumference. The arc-shaped grooves of the mounting turntable 32 correspond to the outer arc surface of the offset arc groove plate 22. The outer arc surface of the mounting turntable 32 corresponds to the outer arc surface of the offset arc groove plate 22. The offset arcs correspond to each other, ensuring that the offset arc groove plate 22 and the mounting turntable 32 will not interfere with each other and prevent rotation. The actuating shaft 23 installed on the platform 21 corresponds to the strip groove on the mounting turntable 32. When the platform 21 rotates, the actuating shaft 23 will enter the strip groove to control the rotation of the mounting turntable 32, thereby controlling the overall rotation of the mounting platform 3. If there is a pair of arc grooves and strip grooves, the mounting platform 3 can rotate 180 degrees. If there are two pairs of arc grooves and strip grooves, the mounting platform 3 can rotate 90 degrees. It can be adjusted freely as needed.

[0035] A grinding unit 5 is also provided inside the frame 1. The grinding unit 5 corresponds to the sliding groove opened on the frame 1 through the sliders extending to both sides. The sliding groove is set synchronously according to its movement trajectory. The grinding unit 5 includes a sliding table 51 and a grinding motor 52. The grinding motor 52 is installed on the sliding table 51. The grinding rope connected to the output end of the grinding motor 52 is manually threaded into the hollow tube of the spindle. The grinding motor 52 can be rotated to grind it.

[0036] A connecting rod 53 is provided on the side of the sliding table 51 away from the mounting table 3. A pull rod 54 is rotatably sleeved on the connecting rod 53 via a bearing. The end of the pull rod 54 extends toward the drive gear 42 and is rotatably sleeved with the connecting handle 43 connected to the side of the drive gear 42. When the drive motor controls the drive gear 42 to rotate, since both ends of the pull rod 54 are sleeved on the connecting rod 53 and the connecting handle 43 via bearings, the connecting handle 43 drives the pull rod 54 to move the sliding table 51 up and down. At the same time, the grinding motor 52 controls the grinding rope to rotate, so that the grinding rope can rotate and grind while the grinding moves up and down.

[0037] To further polish the outer wall of the spindle arm, an extension plate 6 is connected to one side of the connecting rod 53. A contact rod 61 is connected to the extension plate 6, and the contact rod 61 is aligned with the connecting rod 53. A wheel seat 62 is connected to one side of the contact rod 61, and a wheel 63 is mounted on the wheel seat 62. The wheel 63 abuts against the curved-straight composite slide rail 12 and moves along the direction of the curved-straight composite slide rail 12. A spring 64 is also provided between the wheel seat 62 and the extension plate 6 to facilitate its reset. The curved-straight composite slide rail 12 is arranged in the same direction as the spindle arm, and the curved-straight composite slide rail 12 is straight. The linear guide section is connected to the arc-shaped guide section, and the arc of the arc-shaped guide is consistent with the arc of the spindle wing arm. At the other end of the contact rod 61, a pair of extension rods 65 are connected. The extension rods 65 extend outward to both sides and converge at the end. A semi-circular grinding sleeve 66 is connected to the converged extension rod 65 to form a complete grinding sleeve 66. The grinding sleeve 66 is fitted on the spindle wing arm, and the curved and straight composite guide rail 12 controls the grinding sleeve 66 to grind along the shape of the spindle wing arm. The semi-circular design of the grinding sleeve 66 fits the outer wall of the spindle wing arm. Combined with the adaptive pressure of the spring 64, the grinding uniformity is improved.

[0038] The specific workflow is as follows: The spindle arm is installed on the mounting platform 3, making the spindle inverted. The grinding rope of the grinding motor 52 is threaded into the hollow wall of the spindle arm. At this time, the drive motor drives the drive gear 42 to rotate. The connecting handle 43 on the drive gear 42 drives the pull rod 54 to pull the sliding table 51 downward. In conjunction with the rotation of the grinding rope of the grinding motor 52, the hollow spindle arm is ground. At the same time, the pull rod 54 pulls the connecting rod 53 down, which in turn drives the contact rod 61 down. The grinding sleeve 66 is fitted on the spindle arm for grinding. Meanwhile, when the wheel 63 on the contact rod 61 slides along the curved and straight composite slide rail 12 to the lower part, it drives the grinding... Sliding sleeve 66 to one side completes the grinding of the arc surface of the spindle wing arm. Drive gear 42 continues to rotate, and active conical gear 4 controls passive conical gear 25 to rotate, which drives the actuating shaft 23 on platform 21 to correspond with the strip groove on the actuating shaft 23, controlling the installation turntable 32 to rotate 180 degrees. At the same time, pull rod 54 drives sliding table 51 to the top, that is, grinding sleeve 66 is suspended on the top of the rotated spindle wing arm. Continuing to rotate repeats the above steps, which can realize the rotation and lifting of the grinding rope when grinding the hollow wall, while also grinding the outer wall of the spindle wing, and at the same time, the spindle wing can rotate and the outer wall of another spindle wing arm can be ground.
