Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology and relates to a pneumatic device for disassembling and assembling a transverse belt pulley disc assembly. Background Technology

[0002] The transverse pulleys of the ATF1500 texturing machine wear down due to the continuous reciprocating motion of the small belt at the spinning head, and therefore generally need to be completely replaced within a year and a half cycle; otherwise, the quality of the yarn will be affected. Each spindle has one transverse pulley assembly on each side, totaling 768 on a single machine. Due to the sheer number of pulleys, routine replacement requires significant downtime, and the method of disassembling the pulleys determines the efficiency of machine maintenance, thus having a substantial impact on production.

[0003] In existing technology, a power tool is typically used to disassemble the 768 transverse pulley assembly, and a small puller is used for positioning to remove the pulley disc. For example... Figure 3 As shown, the pulley ring is placed into the small puller hole. Three set screws on the circumference of the small puller are screwed in to hold the pulley ring in place. The pulley disc and pulley ring are separated by rotating the axial screw. A new pulley disc is then installed, and the pulley assembly with the replaced pulley disc is then mounted on the machine. This replacement method is very inefficient. In practice, it requires multiple people to work simultaneously and takes a long time to disassemble and reassemble the entire machine, resulting in significant machine efficiency losses.

[0004] Patent CN221436366U discloses a special tool for on-site disassembly of the transverse pulley assembly pulley disc. This patent uses a manual puller to disassemble the transverse pulley disc, which improves disassembly efficiency compared to the aforementioned power tools that require tightening multiple screws. However, in actual operation, prolonged manual pulling and pressing during disassembly can easily cause hand fatigue and injury, making it suitable only for disassembly scenarios with a small number of spindles. When faced with a large number of disassembly tasks, the high-intensity disassembly can cause hand discomfort for machine repair workers, leading to low production efficiency. Furthermore, when workers reinstall the pulley, the large number of participants and the inconvenient on-site installation location, coupled with the fact that assembly accuracy is closely related to the worker's skill, make it difficult to ensure the assembly consistency of the entire machine's pulley discs. In summary, the above solution still has significant limitations.

[0005] Therefore, it is of great significance to study a pneumatic device that combines the assembly and disassembly of a transverse belt pulley assembly in order to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problems existing in the prior art and to provide a pneumatic device that combines the assembly and disassembly of a transverse belt pulley assembly.

[0007] A pneumatic device integrating assembly and disassembly of a transverse pulley assembly is disclosed. The transverse pulley assembly includes a pulley ring and a pulley disc. The pulley ring includes a cylinder A, a cylinder B, and two rings. Cylinder A and cylinder B are hollow cylinders. The two rings are respectively fixed to the upper and lower bottom surfaces of cylinder A. The outer diameter of the rings is larger than the outer diameter of cylinder A, and the inner diameter of the rings is equal to the inner diameter of cylinder A. The outer diameter of cylinder B is smaller than the inner diameter of cylinder A. Cylinder B is inserted into the interior of cylinder A and is fixedly connected to cylinder A by a connector. The height of cylinder B is the height of the pulley ring, which is the sum of the height of cylinder A and the thickness of the two rings. The central axes of the two rings and the central axis of cylinder B are aligned with the central axis of cylinder A. The axes coincide; the pulley disc includes a cylinder C and a vertical rod, the vertical rod is fixed on the upper surface of the cylinder C, and the height of the vertical rod is equal to the height of the pulley ring; the vertical rod is used to insert into the inside of the cylinder B and is interference-fitted with the cylinder B; the two transverse pulley couplings are respectively denoted as transverse pulley coupling I and transverse pulley coupling II, transverse pulley coupling I includes a pulley ring I and a pulley disc I, transverse pulley coupling II includes a pulley ring II and a pulley disc II, and a two-in-one pneumatic device for disassembling and assembling the transverse pulley couplings is used to disassemble the pulley ring I and the pulley disc I in transverse pulley coupling I and to assemble the pulley ring II and the pulley disc II in transverse pulley coupling II;

[0008] The pneumatic device for assembling and disassembling the transverse pulley assembly includes a cylinder, bracket, stamping head, pulley fixing clamp, spring mechanism and base plate;

[0009] The cylinder, the wheel-mounted clamp, the spring mechanism, and the base plate are arranged from top to bottom and are fixedly connected to the bracket respectively;

[0010] The pulley clamp is used to hold the circumferential surface of the cylinder A in the pulley ring I, and to make the central axis of the cylinder A perpendicular to the horizontal plane.

[0011] The base plate is used to place the cylinder C in the pulley plate II. When the cylinder C in the pulley plate II is placed on the base plate, the pulley ring II is placed directly above the pulley plate II. The cylinder B in the pulley ring II is in contact with the vertical rod in the pulley plate II, and the central axis of the pulley ring II coincides with the central axis of the cylinder B in the pulley plate II.

[0012] The piston rod of the cylinder is vertically downward and is fixedly connected to the punch head; when the pulley fixing fixture clamps the circumferential surface of the cylinder A in the pulley ring I, the vertical projection of the punch head on the horizontal plane is located on the upper surface of the vertical rod of the pulley ring I.

[0013] The springback mechanism includes a springback pressure rod, a springback guide cylinder, a horizontal plate, and a springback spring;

[0014] The horizontal plate is fixedly connected to the bracket; the opening of the rebound guide cylinder faces upward, is located below the horizontal plate and is fixedly connected to the horizontal plate; the horizontal plate is provided with through hole I, and the bottom of the rebound guide cylinder is provided with through hole II;

[0015] The spring bar is placed vertically, with its upper end above the horizontal plate and its lower end passing through through hole I and through hole II in sequence.

[0016] When the cylinder C in the pulley II is placed on the base plate and the pulley ring II is placed directly above the pulley II, the vertical projection of the lower end of the spring-loaded rod on the plane containing the upper surface of the pulley ring II overlaps with the upper surface of the pulley ring II.

[0017] A spring is fitted on the spring-loaded rod. One end of the spring is fixedly connected to the bottom of the spring-loaded guide cylinder, and the other end is fixedly connected to the spring-loaded rod.

[0018] Let a be the distance between the bottom of the pulley I and the bottom of the pulley fixing fixture when the pulley disc fixing fixture is stuck on the circumferential surface of the cylinder A in the pulley ring I. The distance between the upper end of the spring-loaded pressure rod and the bottom of the pulley fixing fixture is less than a, so that when the cylinder A in the pulley ring I is stuck, the upper end of the spring-loaded pressure rod is in contact with the lower surface of the cylinder C in the pulley ring I.

[0019] When cylinder C in pulley II is placed on the base plate, the distance between the lower end of the spring-loaded pressure rod and the upper end of the vertical rod in pulley II when the piston rod of the cylinder is not moving downward is denoted as b. When the pulley fixing fixture clamps the circumference of cylinder A in pulley ring I, during the downward movement of the piston rod of the cylinder, the punch head contacts the upper surface of the vertical rod in pulley I and drives pulley I to move downward through the vertical rod in pulley I. When the piston rod of the cylinder is at its maximum range, the lower end of the punch head is located below pulley ring I or flush with the bottom of pulley ring I. When pulley I moves downward, the spring-loaded pressure rod moves downward because the upper end of the spring-loaded pressure rod is in contact with the bottom of pulley I. The downward movement distance of pulley I is equal to b, thereby pressing pulley ring II downward, so that the vertical rod in pulley II is inserted into cylinder B in pulley ring II to complete the assembly.

[0020] As a preferred technical solution:

[0021] As described above, the pneumatic device for assembling and disassembling a transverse pulley assembly further includes a positioning ring. The positioning ring is located above the base plate and is connected to the base plate via a fixing bracket. The inner diameter of the positioning ring is the same as the outer diameter of the ring. The pulley II is placed inside the positioning ring, which is used to position the pulley II, thereby more quickly determining the relative position of the pulley ring II and the pulley II.

[0022] As described above, a pneumatic device for assembling and disassembling a transverse pulley assembly includes a pulley fixing clamp comprising a positioning baffle and a clamping plate. The clamping plate is placed horizontally and fixedly connected to a bracket. The thickness of the clamping plate is less than or equal to the height of cylinder A. The clamping plate is provided with a U-shaped groove and two rectangular grooves. The U-shaped groove is located on the side of the clamping plate, and its cross-section is U-shaped along the horizontal direction. The length direction of the U-shaped groove is perpendicular to the clamping plate. The width of the U-shaped groove is equal to the outer diameter of cylinder A, and the thickness of the U-shaped groove is the thickness of the clamping plate. The two rectangular grooves are located on the upper surface of the clamping plate and are respectively located on both sides of the U-shaped groove. The two rectangular grooves are connected to the U-shaped groove. The positioning baffle is placed vertically and is used to simultaneously insert into the U-shaped groove and the two rectangular grooves to cooperate with the clamping plate and thus lock the circumference of cylinder A in the pulley ring I. When the positioning baffle is simultaneously inserted into the U-shaped groove and the two rectangular grooves, the distance between the positioning baffle and the bottom of the U-shaped groove is the sum of the radius of cylinder A and the radius of the ring.

[0023] The pneumatic device for assembling and disassembling a transverse pulley assembly, as described above, further includes a cylinder fixing plate; the cylinder is fixedly connected to the bracket via the cylinder fixing plate.

[0024] As described above, a pneumatic device for assembling and disassembling a transverse pulley assembly has a base plate positioning hole on the base plate. The base plate positioning hole is used to place the cylinder C in the pulley II, thereby positioning the position of the pulley II.

[0025] Beneficial effects

[0026] (1) The present invention provides a two-in-one pneumatic device for disassembling and assembling a transverse pulley disc assembly. It achieves rapid and accurate positioning through a pulley disc fixing clamp, and then can directly separate the pulley disc quickly and accurately assemble a new pulley disc through the action of the cylinder, which greatly improves production efficiency. The entire disassembly and installation procedure is very convenient and smooth. Compared with the traditional small puller that requires loosening and tightening 4 screws to remove the pulley disc and still requires further installation, the improved operation efficiency is high, greatly reducing downtime and having excellent economic benefits.

[0027] (2) The present invention provides a pneumatic device for disassembling and assembling a transverse belt pulley assembly, which realizes the integration of starting and disassembling. This avoids the disadvantages of manual pulling and pressing disassembly for a long time in the existing improved technology, which causes fatigue and discomfort to the machine repairman's hands and low production efficiency when encountering a large number of high-intensity disassembly tasks. At the same time, due to the high efficiency of disassembly and assembly, the tooling assembly accuracy is guaranteed, avoiding the defect of manual assembly where it is difficult to guarantee the consistency of the assembly accuracy of the whole machine belt pulley due to the large number of workers involved.
