Description

Technical Field

[0001] The utility model relates to the technical field of spinning machines, in particular to a spindle calibration and fixing device for a spinning machine. Background Art

[0002] The spindle of a spinning machine is a key component in the spinning machine, and the spindle plays a crucial role in the spinning process. The spindle rotates at a high speed, driving the yarn to wind, realizing the twisting and winding of the yarn. Among them, the calibration and positioning of the spindle is an important task in the maintenance and optimization of the spinning machine. The purpose of spindle calibration and positioning is to ensure that each spindle is in the correct position and state during the operation of the spinning machine, so as to achieve efficient and high-quality spinning. Accurate calibration and positioning can reduce the jumping and shaking of the spindle, reduce the yarn breakage rate, and improve the uniformity and strength of the yarn. When performing spindle calibration and positioning, professional tools and equipment are required;

[0003] In the utility model with the application number 202221965628.1, a spindle fixing device for a ring spinning machine is disclosed. By arranging the spindle disk in the installation groove, rotating the adjusting screw rod drives the threaded sleeve block to move. The movement of the threaded sleeve block drives the fixing rod to move. The movement of the fixing rod drives the fixing box to move. The movement of the fixing box drives the connecting block to move. The movement of the connecting block drives the arc plate to move. The arc plate elastically abuts against the outer side of the spindle rod under the elastic support of the spring, playing a role in supporting the spindle rod and also having a shock-absorbing effect;

[0004] However, in the above-mentioned spindle fixing device for a ring spinning machine, when the spindle rod rotates, it will generate friction with the arc plate and the abutting block, which easily affects the normal rotation of the spindle rod and easily causes wear of the arc plate and the abutting block. When fixing in the above-mentioned spindle fixing device for a ring spinning machine, it is necessary to manually rotate the adjusting screw rod and the adjusting screw to drive the arc plate and the abutting block to clamp the spindle rod and the spindle disk respectively, and only the rotation condition of the spindle can be observed by the naked eye for calibration, and effective precise calibration cannot be achieved. Therefore, the utility model proposes a spindle calibration and fixing device for a spinning machine to solve the problems existing in the prior art. Summary of the Utility Model

These embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0019] According to Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides a spindle calibration and fixing device for a spinning machine, including a mounting base 1, a spindle 2, a clamping and rotating mechanism, a supporting and rotating mechanism, and a calibration mechanism. The spindle 2 is inserted into the mounting base 1. The clamping and rotating mechanism includes a mounting groove 3, a spindle disc 4, a fixing ring 5, a bearing ring 6, a clamping seat 7, and a clamping mechanism. A mounting groove 3 is opened in the middle of the mounting base 1. The lower end of the spindle 2 is fixedly provided with a spindle disc 4. The spindle disc 4 is correspondingly and cooperatively installed with the mounting groove 3. A fixing ring 5 is fixedly provided at the top of the mounting base 1. A bearing ring 6 is fixedly embedded in the fixing ring 5. A clamping seat 7 is fixedly embedded in the inner ring of the bearing ring 6. The outer ring of the bearing ring 6 is in interference fit with the fixing ring 5, and the inner ring of the bearing ring 6 is in interference fit with the clamping seat 7. A clamping mechanism is provided on the clamping seat 7. A supporting and rotating mechanism is provided in the mounting groove 3. A calibration mechanism is provided on one side of the mounting base 1. When installing, the spindle 2 and the spindle disc 4 are inserted into the mounting groove 3. The clamping seat 7 is cooperatively installed with the inner ring of the bearing ring 6 to achieve that the clamping seat 7 can rotate synchronously under the drive of the clamping abutting block 11 after clamping and fixing, effectively avoiding the problem of wear caused by friction between the spindle 2 and the clamping member when the spindle 2 rotates while ensuring the clamping stability.

[0020] The clamping mechanism includes a threaded hole 8, a screw rod 9, a spring 10 and a clamping abutment 11. The clamping seat 7 is provided with a threaded hole 8 around it. A screw rod 9 is rotatably arranged in the threaded hole 8 in a threaded fit. A spring 10 is fixedly arranged inside the screw rod 9. A clamping abutment 11 is fixedly arranged inside the spring 10. When calibrating and adjusting, after judging the deviation direction of the spindle 2 according to the data measured by the laser rangefinder 21, the screw rod 9 in the corresponding direction is rotated to cooperate with the threaded hole 8 to rotate and push to adjust the position of the clamping abutment 11, so as to calibrate the perpendicularity of the spindle 2.

[0021] The supporting and rotating mechanism includes a first groove 12, a rotating shaft 13, a supporting wheel 14, a second groove 15 and a ball 16. A first groove 12 is provided around the lower part of the installation groove 3. A rotating shaft 13 is rotatably arranged in the first groove 12. A supporting wheel 14 is fixedly arranged on the rotating shaft 13. A second groove 15 is provided around the installation groove 3. A ball 16 is rotatably arranged in the second groove 15 in an embedded manner. The supporting wheel 14 rotates in contact with the bottom of the spindle disk 4, and the ball 16 rotates in contact with the periphery of the spindle disk 4. When the spindle 2 and the spindle disk 4 rotate, the supporting wheel 14 and the ball 16 are driven to rotate, so that the spindle 2 remains stable when rotating in the mounting seat 1.

[0022] The calibration mechanism includes a positioning hole 17, a calibration rod 18, a sliding groove 19, a sliding block 20 and a laser rangefinder 21. A positioning hole 17 is provided on one side of the mounting seat 1. A calibration rod 18 is inserted into the positioning hole 17. Sliding grooves 19 are symmetrically arranged in the front and back of the middle of the calibration rod 18. A sliding block 20 is slidably arranged between the sliding grooves 19. A laser rangefinder 21 is fixedly arranged on the other side of the sliding block 20. The laser rangefinder 21 corresponds to the front and back positions of the spindle 2. When calibrating, the laser rangefinder 21 is turned on to irradiate the rotating spindle 2, and then the sliding block 20 is pushed to slide back and forth along the sliding groove 19 to measure and judge different positions of the spindle 2, which is convenient to calibrate the spindle 2 according to the measurement data and effectively improves the calibration accuracy.

[0023] When the spindle calibration and fixing device of the spinning machine is in use, the spindle and the spindle disk are inserted into the installation groove for installation. After the calibration rod is vertically inserted into the positioning hole, the laser rangefinder is turned on to irradiate the spindle. The screw rod is rotated to cooperate with the threaded hole to drive the spring and the clamping abutment to move inward to clamp and limit the spindle. After the spindle is driven to rotate, the clamping abutment and the screw rod drive the clamping seat to rotate synchronously with the bearing ring for the spindle, and the perpendicularity of the spindle is judged according to the measurement data. The position of the clamping abutment is adjusted by rotating the screw rod at the corresponding position according to the measurement data to calibrate the spindle.
