[0022] Specifically, refer to Figure 4-Figure 7The motor shaft tightening mechanism includes a regular hexagonal frame 14, a circular ring 15 and a horn 16. The regular hexagonal frame 14 is fixedly mounted at the bottom position of one end of the two sliding frames 13 close to each other. The bottom positions of the two sliding frames 13 close to each other are fixed with vertical plates. The regular hexagonal frame 14 is fixedly mounted at the bottom of the two vertical plates. The circular ring 15 is fixedly mounted on the top of the regular hexagonal frame 14. An external thread is provided on the outer wall of the circular ring 15. The top of the horn 16 is integrally formed with a circular sleeve. The inner wall of the circular sleeve is provided with an internal thread. The horn 16 is sleeved on the circular ring 15 through the circular sleeve thread. The regular hexagonal frame 14 Three rectangular slide bars 18 with rotational symmetry are installed on the upper slide. The ends of the three rectangular slide bars 18 close to each other extend into the regular hexagonal frame 14, and are all provided with a resistance block 19. In this embodiment, the resistance block 19 is fixedly installed on the rectangular slide bar 18 by the cooperation of a screw and a nut. An inner arc surface is provided on the resistance block 19. The diameter of the circle to which the inner arc surface belongs is the same as the diameter of the roller shaft to ensure that the inner arc surface can fit with the surface of the roller shaft, and the inner arc surface is frosted to increase the friction with the roller shaft. The ends of the three rectangular slide bars 18 away from each other are movably inlaid with balls 22. The three balls 22 are in contact with the inner wall of the horn 16. When the horn 16 is rotated clockwise, it will gradually move downward. The diameter of the horn 16 gradually increases from top to bottom. In the process of descending, the inner wall of the horn 16 will move toward the center direction of the regular hexagonal frame 14 by pushing the rectangular slide bar 18. A ring 20 is fixedly sleeved on the rectangular slide bar 18. A second spring 21 is sleeved on the rectangular slide bar 18. One end of the second spring 21 is fixedly connected to the regular hexagonal frame 14, and the other end is fixedly connected to the ring 20. In the initial state, the second spring 21 is in a compressed state. It gives the ring 20 a reverse elastic force so that the ball 22 can always contact the inner wall of the horn 16. When the rectangular slide bar 18 moves toward the center of the regular hexagonal frame 14, the second spring 21 will be further compressed. When the horn 16 moves upward, the rectangular slide bar 18 can be reset under the elastic force of the second spring 21. A plurality of hand rods 17 are fixedly installed on the outer wall of the horn 16 to facilitate the rotation of the horn 16. An anti-slip ball is threadedly sleeved on one end of the hand rod 17 away from the horn 16 to prevent the user's hands from slipping when rotating the horn 16.

[0023] In this embodiment, in order to clamp and fix the roller shaft, refer to Figure 2-Figure 3 A clamping rod 10 is slidably installed on the outer wall of the positioning cylinder 9, and a first end block 11 is fixedly installed on one end of the clamping rod 10. A first spring 12 is sleeved on the clamping rod 10, and one end of the first spring 12 is fixedly connected to the first end block 11, and the other end is fixedly connected to the positioning cylinder 9. The end of the clamping rod 10 away from the first end block 11 is also provided with an inner arc surface adapted to the roller shaft, and the inner arc surface is also frosted.

[0024] In this embodiment, in order to prevent the sliding frame 13 from sliding upward during the rotation of the horn 16 and causing the fixing point of the motor center axis to be incorrect, a limiting strip 37 is slidably installed on the inner wall of one side of the gantry 2, and the bottom of the limiting strip 37 contacts the top of the corresponding sliding frame 13.

[0025] In this embodiment, in the non-working state, in order to keep the positioning cylinder 9, the pressure rod 3 and other components at a high position, a magnet block is fixedly installed on the outer wall of one side of the gantry 2 close to the operating round rod 8 and close to the top position. The magnet block will attract the sliding arm 4 so that it cannot slide downward by itself without the intervention of external force.

[0026] In this embodiment: When in use, first lift the two sliding frames 13 and the motor shaft pressing mechanism with one hand, so that there is enough distance between the motor shaft pressing mechanism and the base 1 to place the motor, and then place the motor in the motor positioning groove 101 with the other hand, and then put down the sliding frame 13. Under the action of gravity, the sliding frame 13 moves downward to the initial position. During this process, the central axis of the motor will enter between the three abutment blocks 19, and the axis line of the central axis of the motor will coincide with the center point of the regular hexagonal frame 14, and then push the limiting bar 37 forward to move it to the top of the right sliding frame 13, so as to prevent the sliding frame 13 from moving upward; After completing the above operations, the horn 16 is screwed clockwise through the hand lever 17. The horn 16 moves downward in the process of clockwise rotation, and pushes the three rectangular slide bars 18 to move toward the center point of the regular hexagonal frame 14 at the same time in the process of descending. The three second springs 21 are compressed to store elastic potential energy. As the horn 16 continues to move downward, the inner arc surfaces of the resistance blocks 19 on the three rectangular slide bars 18 will eventually fit with the central axis of the motor. Thereafter, the horn 16 is rotated forcefully to apply sufficient pre-tightening force to the horn 16, so that the three resistance blocks 19 can be pressed against the motor center axis. The center axis of the motor is pressed tightly; then the first end block 11 is pulled to the right to drive the clamping rod 10 to slide to the right, in order to avoid the roller shaft, and then, the top end of the roller shaft is inserted into the positioning cylinder 9 without resetting the clamping rod 10. The inner diameter of the positioning cylinder 9 is the same as the diameter of the roller shaft, so after the roller shaft is inserted into place, its axis center line will coincide with the axis center line of the motor shaft, and after the first end block 11 is released, under the pulling force of the first spring 12, the clamping rod 10 will move to the left, and the left end of the clamping rod 10 will conflict with the roller shaft, so that the roller shaft is limited to a certain extent and will not fall by itself; After that, the operating rod 8 is held and pressed downward. During the downward rotation of the operating rod 8, the sliding sleeve 5 is driven to move downward. During the downward movement of the sliding sleeve 5, it slides relatively with the operating rod 8, and the sliding sleeve 5 drives the sliding arm 4 to slide downward, and the pressing rod 3 drives the roller shaft to gradually move downward, so that the roller shaft is sleeved on the motor center shaft through the hole at its bottom. The operating rod 8 continues to rotate downward, and the roller shaft further descends. When the sliding arm 4 conflicts with the bottom inner wall of the strip sliding opening on the gantry 2, the roller shaft is pressed into place. During the process of pressing the roller shaft onto the motor center shaft, the motor center shaft has been pre-tightened and fixed by the motor shaft tightening mechanism, and is supported relative to the motor center shaft, so the motor center shaft can be effectively prevented from loosening due to excessive pressure. After the pressing is completed, first rotate the horn 16 counterclockwise to separate the three resistance blocks 19 from the central axis of the motor, and then lift the operating rod 8 upward until the sliding arm 4 contacts the magnet block, and then pull the limiting strip 37 backward to separate it from the sliding frame 13 on the right, and then lift the two sliding frames 13 and the motor shaft clamping mechanism upward to a higher position, and then the motor and the pressed roller shaft can be taken out together.

[0027] Compared with the related art, the roller shaft pressing tool for a spinning machine provided by the present invention has the following beneficial effects: By arranging the pressure rod 3, the sliding arm 4, the sliding sleeve 5, the operating round rod 8, the positioning cylinder 9, the clamping rod 10, the first end block 11, the first spring 12 and other components, when in use, after placing the motor in the motor positioning groove 101, the roller shaft is inserted into the positioning cylinder 9 and clamped and fixed by the clamping rod 10, and then the operating round rod 8 is pressed downward, the roller shaft can be pressed onto the central axis of the motor, which has the advantages of simple operation and fast pressing; by arranging the two sliding frames 13 and the motor shaft tightening mechanism, before pressing the roller shaft, the horn 16 on the motor shaft tightening mechanism is rotated clockwise, so that the three contact blocks 19 on the motor shaft tightening mechanism can tighten and fix the central axis of the motor, which can effectively prevent the central axis of the motor from loosening during the pressing process, and has the advantages of good protection effect on the central axis of the motor and reliable use.

[0028] Second embodiment: Based on the roller shaft pressing tool for a spinning machine provided in the first embodiment of the present application, the second embodiment of the present application provides another roller shaft pressing tool for a spinning machine. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0029] The second embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0030] Please refer to Figure 10-Figure 14In the roller shaft pressing tool of the spinning machine proposed in this embodiment, the interference block 19 and the rectangular slide bar 18 are designed to be quickly detachable. Specifically, an L-shaped mounting plate 23 is fixedly installed at one end of the rectangular slide bar 18 located in the regular hexagonal frame 14, and the interference block 19 is installed on the L-shaped mounting plate 23. Two avoidance grooves 2301 are provided on the top of the L-shaped mounting plate 23. Two connecting rods 24 are fixedly installed on the interference block 19. The two connecting rods 24 are respectively located in the two avoidance grooves 2301 and are slidably connected to the inner walls on both sides of the corresponding avoidance grooves 2301. A fixed block 25 is fixedly installed at one end of the two connecting rods 24 away from the interference block 19. The outer walls of the two fixed blocks 25 on one side close to the interference block 19 are in contact with the L-shaped mounting plate 23. A limiting groove 2501 is provided on the inner wall of the side where the blocks 25 are close to each other, and two fixing seats 29 are fixedly installed on the L-shaped mounting plate 23. Sliding bars 30 are penetrated and slidably installed on the two fixing seats 29. The ends of the two sliding bars 30 that are away from each other extend into the corresponding limiting groove 2501, and the bottoms are in contact with the bottom inner walls of the corresponding limiting groove 2501. The end surfaces of the ends of the two sliding bars 30 that are away from each other are provided with inclined sliding surfaces. The two sliding bars 30 are sleeved with fourth springs 32. The ends of the two sliding bars 30 that are close to each other are fixedly installed with second end blocks 31. One end of the fourth spring 32 is fixedly connected to the second end block 31, and the other end is fixedly connected to the fixing seat 29. In the process of installing the interference block 19, the fixing The block 25 will first conflict with the inclined sliding surface, giving the inclined sliding surface a vertical thrust. Under the horizontal component of the thrust, the sliding block 30 moves in the direction of the middle dividing surface of the L-shaped mounting plate 23. Subsequently, one end of the sliding block 30 with the inclined sliding surface will conflict with the fixed block 25 and slide relative to the fixed block 25. When the conflicting block 19 is installed in place, the fixed block 25 also drops to the lowest point. At this time, the bottom of the sliding block 30 and the bottom inner wall of the limiting groove 2501 are in the same horizontal plane. The sliding block 30 loses its obstruction. Under the pulling force of the fourth spring 32, the end of the sliding block 30 with the inclined sliding surface will automatically enter the limiting groove 2501. A plurality of smooth holes are provided on the fixed block 25, one of which is aligned with the limiting groove 2501. The push rods 26 are connected, and push rods 26 are slidably installed in multiple smooth holes. The same hand-pinch plate 27 is fixedly installed at one end of the push rods 26 outside the fixed block 25. A third spring 28 is sleeved on the push rods 26. One end of the third spring 28 is fixedly connected to the fixed block 25, and the other end is fixedly connected to the hand-pinch plate 27. In the process of pushing the hand-pinch plate 27 close to the fixed block 25, the third spring 28 will be compressed, and the multiple push rods 26 will move in the direction of the middle dividing surface of the L-shaped mounting plate 23, and the push rod 26 in the smooth hole connected to the limiting groove 2501 will conflict with the sliding stop bar 30. As the hand-pinch plate 27 continues to approach the fixed block 25, the push rod 26 will push the sliding stop bar 30 out of the limiting groove 2501, and no longer restrict the fixed block 25.Two limiting blocks are fixedly mounted on the outer wall of the two fixed blocks 25 away from each other. After the hand-kneading plate 27 contacts the limiting blocks, it cannot move closer to the fixed blocks 25.

[0031] In this embodiment, in order to increase the limiting force on the resistance block 19, two limit shafts 33 are fixedly installed on the bottom inner wall of the L-shaped mounting plate 23, and two limit circular grooves are opened at the bottom of the resistance block 19. The top ends of the two limit shafts 33 extend into the corresponding limit circular grooves, and the connection between the end faces of the top ends of the two limit shafts 33 and the circular outer wall is designed with rounded corners, so that the limit shafts 33 can smoothly enter the limit circular grooves.

[0032] In this embodiment, during the installation of the abutment block 19 , in order to allow the fixing block 25 to smoothly move down to the back of the L-shaped mounting plate 23 , the connection between the outer wall of one side of the L-shaped mounting plate 23 close to the sliding stop bar 30 and the top is chamfered.

[0033] In this embodiment: When the abutment block 19 needs to be replaced, for example, when the frosted inner arc surface is severely worn and needs to be replaced, the two hand-pinching plates 27 are pinched by the index finger and the thumb at the same time to make the two hand-pinching plates 27 move toward each other. Driven by the two hand-pinching plates 27, the multiple push rods 26 will move in the direction of the middle dividing surface of the L-shaped mounting plate 23, and the push rods 26 in the smooth holes connected to the limiting grooves 2501 will enter the limiting grooves 2501 and push the sliding stop bars 30 to move. When the two hand-pinching plates 27 are in conflict with the corresponding limiting blocks, the two sliding stop bars 30 will be pushed out of the corresponding limiting grooves 2501, so that the two fixed blocks 25 are no longer restricted. After that, the two hand-pinching plates 27 are lifted up while ensuring that they are not reset, so as to drive the two fixed blocks 25 to move upward. The two fixed blocks 25 drive the abutment block 19 to move upward through the corresponding connecting rods 24, so that the abutment block 19 can be taken out. When installing a new abutment block 19, align the two limiting circular grooves at the bottom of the abutment block 19 with the two limiting shafts 33 respectively and press downward, the two connecting rods 24 on the abutment block 19 will enter the two avoidance grooves 2301 respectively, and the two fixing blocks 25 will be at the back of the L-shaped mounting plate 23 and descend, and the two fixing blocks 25 will first abut against the inclined sliding surfaces on the corresponding sliding bars 30, pushing the two sliding bars 30 to move toward each other, and subsequently, the two sliding bars 30 will be pulled by the corresponding fourth spring 32, and one end with the inclined sliding surface will abut against the two fixing The outer walls of the blocks 25 that are close to each other collide with each other and slide relative to each other. After the conflicting block 19 is installed in place, the fixed block 25 drops to the lowest point. At this time, the bottoms of the two sliding bars 30 are at the same level as the bottom inner walls of the corresponding limiting grooves 2501. Under the pulling force of the fourth spring 32, the ends of the two sliding bars 30 with the inclined sliding surfaces will automatically enter the limiting grooves 2501, thereby restricting the two fixed blocks 25 to prevent the fixed blocks 25 from sliding upward. When the fixed blocks 25 are restricted, the conflicting block 19 cannot move either. The present embodiment provides the L-shaped mounting plate 23, the fixed block 25, the push rod 26, the hand pinching plate 27, the third spring 28, the sliding stop bar 30, the fourth spring 32 and other components. When replacing the conflicting block 19, it is only necessary to pinch the two hand pinching plates 27 with two fingers to move the two hand pinching plates 27 toward each other, so that the restriction of the two sliding stop bars 30 on the fixed block 25 can be released, and then the two hand pinching plates 27 can be pinched to take out the conflicting block 19 upward; when installing a new conflicting block 19, it is only necessary to align the two positioning circular grooves at the bottom of the conflicting block 19 with the two limit shafts 33 respectively and press down. When the conflicting block 19 is pressed into place, the two sliding stop bars 30 will automatically insert into the corresponding limiting grooves 2501 on the fixed block 25, so that the conflicting block 19 is reliably restricted. The operation is simple and quick, and can be completed without the use of tools, thereby effectively improving the replacement efficiency of the conflicting block 19.

[0034] Third embodiment: Based on the roller shaft pressing tool for a spinning machine provided in the second embodiment of the present application, the third embodiment of the present application provides another roller shaft pressing tool for a spinning machine. The third embodiment is only a preferred embodiment of the second embodiment, and the implementation of the third embodiment will not affect the independent implementation of the second embodiment.

[0035] The third embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0036] Please refer to Figure 15-17 In the roller shaft press-fitting of the spinning machine proposed in this embodiment, a curved strip 35 is also fixedly mounted on the inner wall of one side of the gantry 2, as shown in FIG. Fig.17The curved strip 35 includes a lower vertical portion 3501, a guide portion 3502, an upper vertical portion 3503 and a guide head 3504. The guide portion 3502 is arranged between the lower vertical portion 3501 and the upper vertical portion 3503. The guide head 3504 is arranged at the top of the upper vertical portion 3503. The lower vertical portion 3501, the guide portion 3502, the upper vertical portion 3503 and the guide head 3504 are an integrated structure. A fixed round rod 34 is fixedly installed on the outer ring of the first end block 11. A rotating sleeve 36 is rotatably provided on the fixed round rod 34. The outer wall of the rotating sleeve 36 is in contact with the lower vertical portion 3501.

[0037] In this embodiment, in order to increase the firmness of the fixed round rod 34 , three reinforcing rods are welded to the first end block 11 , and ends of the three reinforcing rods away from the first end block 11 are all welded and fixed to the fixed round rod 34 .

[0038] In this embodiment: After the roller shaft is inserted into the positioning cylinder 9 and fixed by the clamping rod 10, during the process of pressing the operating round rod 8 downward for press-fitting, the positioning cylinder 9, the clamping rod 10, the first end block 11, the fixed round rod 34 and other components follow the pressure rod 3 to move downward. When the roller shaft contacts the central axis of the motor, the rotating sleeve 36 on the fixed round rod 34 contacts the curved bar 35, and then the pressure rod 3 continues to press downward, and the rotating sleeve 36 will drop to the right side of the upper vertical portion 3503. At this time, the rotating sleeve 36 only contacts the upper vertical portion 3503 without being subjected to thrust. When the rotating sleeve 36 drops to the position of the guide portion 3502, the roller shaft has been pressed a certain distance, and the subsequent rotating sleeve 36 will continue to move to the right under the bottom of the guide portion 3502. The rotating sleeve 36 drives the first end block 11 to move to the right through the fixed round rod 34. The first end block 11 brings The movable clamping rod 10 moves, so that the clamping rod 10 is separated from the roller shaft. Since the roller shaft has been pressed a certain distance at this time, it will not be affected after losing the clamping of the clamping rod 10. When the rotating sleeve 36 drops to the lower vertical part 3501, it will no longer move to the right further; after the roller shaft is pressed, the rotating sleeve 36 drops to a position close to the bottom of the lower vertical part 3501, and then in the process of lifting the operating round rod 8 downward, the pressure rod 3 is reset upward, driving the positioning cylinder 9 to rise. In the process of the positioning cylinder 9 rising, the first end block 11, the fixed round rod 34 and other components are driven to rise. After the positioning cylinder 9 is separated from the roller shaft, the fixed round rod 34 will move to the lower position of the guide part 3502. Subsequently, as the pressure rod 3 continues to rise, when passing through the guide part 3502, the first end block 11 automatically completes the reset under the pulling force of the first spring 12; In this embodiment, by setting up components such as the fixed round rod 34, the curved strip 35, and the rotating sleeve 36, during the press-fitting process of the roller shaft, the clamping rod 10 can be separated from the roller shaft after the roller shaft is pressed for a certain distance. After the press-fitting is completed, the clamping rod 10 will be reset only after the positioning cylinder 9 is separated from the roller shaft. In this way, the relevant operating personnel do not need to operate the clamping rod 10 after the press-fitting is completed, thereby further improving the convenience of using the roller shaft pressing tool of the textile machine.
