Description

Technical Field

[0001] This utility model relates to the field of textile spindles, specifically to a circumferential initial positioning device for textile spindles. Background Technology

[0002] The oil injection hole positioning device for textile spindles is a key component used to precisely guide the injection of lubricating oil into the spindle bearing. It is typically integrated into the spindle seat or spindle shell structure. Its design must ensure precise alignment between the oil hole and the spindle lubrication point to achieve efficient lubrication and reduce frictional losses. This device usually includes locating pins, guide grooves, or visual markings for easy maintenance, while also ensuring a tight seal to prevent oil leakage, thereby extending the spindle's service life and ensuring stable operation during the spinning process.

[0003] Chinese patent CN106995953B discloses a textile spindle clamping and positioning assembly, including a spindle and a spindle base. The spindle base is equipped with a core-setting mechanism, which includes a transmission gear, a first rack meshing with the top of the transmission gear, a second rack meshing with the bottom of the transmission gear, a right clamping block connected to the first rack, and a left clamping block connected to the second rack. In operation, a textile bobbin is fitted onto the spindle, with the top of the spindle protruding from the bobbin. The transmission gear drives the first and second racks to move linearly, causing the right and left clamping blocks to move towards each other, thus clamping the top of the spindle and reducing the vibration amplitude of the spindle during winding. However, this device still has the following problems:

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0032] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0033] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7 A circumferential initial positioning device for textile spindles, comprising a base 1;

[0034] The base 1 is equipped with a clamping and lifting assembly 2 for clamping the textile spindle and making it rise and rotate at the same time;

[0035] The base 1 is equipped with an oil injection hole positioning mechanism 3, which positions the oil injection hole of the textile spindle held by the clamping and lifting assembly 2 and detects whether it is centered and clamped.

[0036] like Figure 2 and Figure 3As shown, the clamping and lifting assembly 2 includes a lifting drive assembly 21, a lifting assembly 22, and a clamping rotation assembly 23; the base 1 and the lifting assembly 22 are both connected to the lifting drive assembly 21; the base 1 and the clamping rotation assembly 23 are both connected to the lifting assembly 22; the clamping rotation assembly 23 is connected to the base 1; the lifting drive assembly 21 is used to drive the lifting assembly 22; the lifting assembly 22 is used to drive the clamping rotation assembly 23 to rise and fall, and the clamping rotation assembly 23 is used to clamp the textile spindle and make the textile spindle rotate while being driven to rise by the lifting assembly 22;

[0037] In this invention, when the textile spindle is conveyed to the clamping and rotating assembly 23, the clamping and rotating assembly 23 starts to clamp the textile spindle; then the lifting drive assembly 21 starts to drive the lifting assembly 22 to move the clamping and rotating assembly 23 upward. While the clamping and rotating assembly 23 moves upward, it drives the textile spindle to rotate. At the same time, the oil injection hole positioning mechanism 3 detects whether the textile spindle is centered and clamped; and at the same time, it positions the oil injection hole, realizing fully automatic positioning of the oil injection hole of the textile spindle and simultaneous detection of whether the textile spindle is centered.

[0038] The lifting drive assembly 21 includes a servo motor 211 and a transmission assembly 212; the servo motor 211 is fixedly connected to the rear end of the base 1, and the drive end of the servo motor 211 is connected to the transmission assembly 212; the transmission assembly 212 is connected to the lifting assembly 22.

[0039] The lifting assembly 22 includes a rotating shaft 221, a lead screw 222, and a sliding block 223. The rotating shaft 221 is driven by the servo motor 211 via a transmission assembly 212. The rotating shaft 221 is rotatably connected to the base 1. The upper end of the rotating shaft 221 is fixedly connected to the lead screw 222. The lead screw 222 is threadedly connected to the sliding block 223. The sliding block 223 is connected to the clamping and rotating assembly 23. The upper end of the lead screw 222 is rotatably connected to the base 1.

[0040] The transmission assembly 212 adopts a synchronous belt and synchronous pulley transmission assembly, wherein the two synchronous pulleys of the transmission assembly 212 are fixedly connected to the drive end of the servo motor 211 and the rotating shaft 221 respectively, so that the drive end of the servo motor 211 can precisely control the rotation of the rotating shaft 221.

[0041] The clamping and rotating assembly 23 includes a fixed frame 231, a rotating electric claw 232, a stop block 233, and a photoelectric sensor 234. The rear end of the fixed frame 231 is fixedly connected to the sliding block 223, and the fixed frame 231 is slidably connected to the base 1 via a slider rail. The front end of the fixed frame 231 is fixedly connected to the rotating electric claw 232.

Photoelectric sensors 234 are fixedly installed on the left and right side walls of the base 1, and blocking blocks are fixedly installed at both ends of the fixed frame 231.

[0042] In this invention, after the textile spindle is conveyed above the rotary electric gripper 232, the rotary electric gripper 232 starts to clamp the textile spindle. The clamped textile spindle rests against the upper end of the stop block 233. Then, the servo motor 211 starts. The drive end of the servo motor 211 drives the rotating shaft 221 to rotate through the transmission component 212. The rotation of the rotating shaft 221 drives the lead screw 222 to rotate. The rotation of the lead screw 222 drives the sliding block 223 to slide to the upper limit. The sliding block 223 drives the fixed frame 231 to slide to the upper limit. The fixed frame 231 drives the sensing blocks at both ends and the textile spindle to move upward synchronously through the rotary electric gripper 232. When the blocking block passes the photoelectric sensor 234, the blocking block blocks the electrical signal of the photoelectric sensor 234. When the blocking block blocks the electrical signal of the photoelectric sensor 234, the rotary electric gripper 232 starts, so that the rotary electric gripper 232 drives the textile spindle to rotate while rising, which facilitates the positioning mechanism 3 of the oil injection hole to position the oil injection hole of the textile spindle and to detect whether it is centered.

[0043] like Figure 2 and Figure 3 As shown, the oil injection hole positioning mechanism 3 includes a workpiece detection component 31, a positioning drive component 32, and a floating positioning component 33; the workpiece detection component 31 is connected to the base 1; both the base 1 and the floating positioning component 33 are connected to the positioning drive component 32; the base 1 is connected to the floating positioning component 33; the workpiece detection component 31 is used to detect whether the textile spindle is centered and clamped, the positioning drive component 32 is used to drive the floating positioning component 33 to abut against the textile spindle, and the floating positioning component 33 is used to position the oil injection hole of the textile spindle;

[0044] The workpiece detection assembly 31 includes a sensor fixing plate 311 and a detection sensor 312; the sensor fixing plate 311 is fixedly connected to the base 1, and the detection sensor 312 is fixedly connected to the sensor fixing plate 311.

[0045] The positioning drive assembly 32 includes an electric cylinder 321, a fixed plate 322, and a fixed shell 323; the electric cylinder 321 is fixedly connected to the base 1; the drive end of the electric cylinder 321 is fixedly connected to the fixed plate 322, the fixed shell 323 is fixedly connected to the fixed plate 322, and the floating positioning assembly 33 is connected to the fixed shell 323.

[0046] The floating positioning assembly 33 includes a displacement sensor 331, a floating block 332, a connecting rod 333, and a compression spring 334. The upper end of the displacement sensor 331 is fixedly connected to the base 1, and the lower end of the connecting rod 333 is fixedly connected to it. The upper end of the connecting rod 333 is fixedly connected to the floating block 332, and the floating block 332 is slidably connected to the fixed shell 323 through a limiting groove inside the fixed shell 323. The compression spring 334 is sleeved on the floating block 332, with its front end fixedly connected to the floating block 332 and its rear end fixedly connected to the inner wall of the fixed shell 323. A ball bearing is installed at the front end of the floating block 332.

[0047] In this invention, the rotating electric gripper 232 clamps the textile spindle and rotates while rising. At this time, the detection sensor 312 is aligned with the rotation axis of the textile spindle to detect whether the gripping of the textile spindle is centered. Simultaneously, the electric cylinder 321 drives the fixed shell 323 and the floating block 332 to move closer to the textile spindle through the fixed plate 322 until the ball bearing at the front end of the floating block 332 abuts against the textile spindle. At this time, the rotating electric gripper 232 clamps the textile spindle and rotates while rising until the floating block 332 is aligned with the oil injection hole. The ball bearing at the front of the floating block 332 floats forward and locks the oil injection hole under the drive of the compression spring 334. At the same time, after the displacement sensor 331 receives the displacement signal through the floating block 332 and the connecting rod 333, the servo motor 211 and the rotating electric gripper 232 stop driving simultaneously, stopping the rotation and rising of the textile spindle, thus completing the positioning of the oil injection hole of the textile spindle.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
