Description

Technical Field

[0001] The present invention relates to the technical field of belt pulley removal, and specifically to a belt pulley removal tooling for a doubling frame. Background Art

[0002] The belt pulley of the doubling frame is fixed on the transmission shaft through a keyway or interference fit. After long-term use, it is prone to wear or aging and needs to be replaced. Traditional disassembly and assembly methods mostly use crowbars, hammering, or hydraulic pullers.

[0003] However, the existing methods for replacing the belt pulley have the following problems:

[0004] 1. During the process of disassembling and replacing the belt pulley, there is a situation where the distance between the bottom surface of the belt pulley and the doubling frame body is relatively small. Since the grasping claws of ordinary pullers are relatively thick, they cannot grasp one end of the belt pulley located on the doubling frame. And since the belt pulley is made of aluminum material, it is very easy to break the belt pulley when knocking it for disassembly, and only a new belt pulley can be replaced.

[0005] 2. The belt pulley has different types of sizes. For belt pulleys of different sizes, due to the different frictions between the belt pulley and the transmission shaft of the doubling frame, it is necessary to use pullers with grasping claws of different thicknesses to grasp and disassemble the belt pulley, and avoid using grasping claws with a smaller thickness to grasp large-sized belt pulleys, which may cause deformation and damage of the grasping claws.

[0006] The above content is only used to assist in understanding the technical solution of the present invention, and does not represent an admission that the above content is the closest prior art. Summary of the Invention

Detailed implementation

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0046] The belt pulley removal tooling for a doubling machine includes:

[0047] A grasping unit 1, including a thickness adjustment assembly 12 for grasping and adjusting belt pulley parts 101 with different thicknesses from the outside of the doubling machine drive shaft 100, and a diameter adjustment assembly 11 provided at the upper end of the thickness adjustment assembly 12 for grasping and adjusting belt pulleys with different outer diameters;

[0048] An ejecting unit 2, provided inside the diameter adjustment assembly 11, for cooperating with the grasping unit 1 to pull out the belt pulley part 101 from the outside of the doubling machine drive shaft 100.

[0049] It should be noted that: when removing belt pulley parts 101 of different sizes or belt pulleys with different spacings between the belt pulley parts 101 and the doubling machine body, by selecting a suitable thickness adjustment assembly 12 to align with the belt pulley part 101 at one end of the doubling machine body, and adjusting the thickness adjustment assembly 12 into the gap between the belt pulley part 101 and the doubling machine body through the diameter adjustment assembly 11, rotating the ejecting unit 2, the ejecting unit 2 is tightened against one end of the doubling machine drive shaft 100, and the belt pulley part 101 is pulled out along the outside of the doubling machine drive shaft 100 under the action of the diameter adjustment assembly 11 through the thickness adjustment assembly 12, so that it can be used to climb out belt pulley parts 101 of different sizes and with a small spacing from the doubling machine body, and has a wide application range.

[0050] As an improvement, as Figures 1-2 shown, the ejection unit 2 includes:

[0051] A round block 21, inside which there is a second threaded hole 211;

[0052] A screw rod 22, threadedly connected inside the second threaded hole 211, and the screw rod 22 is abutted against one end of the doubling machine transmission shaft 100;

[0053] A rotating rod 23, fixedly connected to the upper end of the screw rod 22, for rotating and adjusting the screw rod 22.

[0054] Furthermore, as Figure 1 , Figure 3 shown, the diameter adjusting assembly 11 includes:

[0055] Three guide plates 111, fixedly connected to the outside of the round block 21 at equal angles;

[0056] A guide rail 1111, arranged inside the guide plate 111, and openings are provided at the upper and lower ends of the guide plate 111 and located inside the guide rail 1111;

[0057] A slider 115, slidably connected inside the guide rail 1111, for grasping and adjusting the thickness adjusting assembly 12.

[0058] Even further, the diameter adjusting assembly 11 further includes:

[0059] A support rod 112, fixedly connected to the upper end of the guide plate 111, the support rod 112 is in an n shape, and a first threaded hole 1121 is provided through the middle of its upper end;

[0060] A T-shaped shaft 113, threadedly connected to the first threaded hole 1121;

[0061] A push rod 114, slidably inserted up and down inside the guide plate 111 and located above the slider 115, for tightly limiting the slider 115.

[0062] Wherein, a limiting disk 1131 is fixedly connected to the lower end of the T-shaped shaft 113;

[0063] A circular groove 1141 is provided inside the push rod 114, for vertically limiting the limiting disk 1131.

[0064] As an improvement, as Figure 2 , Figures 5-6 shown, the thickness adjusting assembly 12 includes:

[0065] A connecting rod 121, fixedly connected to the lower end of the slider 115, and a receiving hole 1212 is provided near the lower part inside the connecting rod 121;

[0066] The rotating shaft 122 is rotatably connected inside the accommodation hole 1212. A limiting groove 1221 is provided on the outer side of the rotating shaft 122 and inside the connecting rod 121. A limiting hole 1211 for limiting the rotating shaft 122 is provided inside the connecting rod 121 and outside the limiting groove 1221;

[0067] The lifting block 123 is fixedly connected to the lower end of the rotating shaft 122;

[0068] The grasping block 124 is fixedly connected to one end of the lifting block 123 and is used for pulling out the belt pulley member 101;

[0069] The grasping disk 125 is arranged at one end of the lifting block 123 opposite to the grasping block 124 and is used for pulling out the belt pulley member 101 that the grasping block 124 cannot be inserted into.

[0070] Further, as Figures 5-6 shown, the grasping disk 125 includes:

[0071] The arc-shaped top plate 1251 is fixedly connected to the lower part inside the grasping disk 125. The radian of the arc-shaped top plate 1251 is equal to the radian of the grasping disk 125, and the thickness of the arc-shaped top plate 1251 is less than the thickness of the first grasping mechanism;

[0072] The accommodation groove 1252 is arranged inside the arc-shaped top plate 1251. The accommodation groove 1252 is set as an arc shape coaxial with the grasping disk 125 and is used for accommodating the double-twisting machine drive shaft 100.

[0073] It should be noted that: in the specific implementation process of the present invention, as Figures 1-4 shown, when removing the belt pulley member 101 with a small distance from the double-twisting machine body from the outside of the double-twisting machine drive shaft 100, the corresponding lifting blocks 123 are rotated respectively. The lifting block 123 drives the grasping disk 125 to point to the gap between the belt pulley member 101 and the double-twisting machine body. Then, the corresponding sliders 115 are moved along the guide rail 1111 respectively. The slider 115 drives the rotating shaft 122 to move through the connecting rod 121. The rotating shaft 122 drives the grasping disk 125 to move towards the gap between the belt pulley member 101 and the double-twisting machine body through the lifting block 123, so that the arc-shaped top plate 1251 with a small thickness is inserted into the gap between the belt pulley member 101 and the double-twisting machine body. The T-shaped shaft 113 is rotated. Under the action of the tangential force of the thread between the T-shaped shaft 113 and the first threaded hole 1121, the ejector rod 114 is driven to move downward, so that the ejector rod 114 abuts against the upper end of the slider 115, completing the limitation of the adjusted slider 115, and thus being able to achieve the effect of grasping the belt pulley member 101 with different outer diameters and a small distance from the double-twisting machine body;

[0074] AsFigures 1-2 As shown, subsequently, rotate the rotating rod 23. The rotating rod 23 drives the screw rod 22 to rotate within the second threaded hole 211. Under the action of the tangential force of the thread between the screw rod 22 and the second threaded hole 211, the upper end of the double-twisting machine transmission shaft 100 is tightened. During this process, due to the reverse acting force of the double-twisting machine transmission shaft 100 on the screw rod 22, the screw rod 22 drives the connecting rod 121 to move upward under the action of the guide plate 111 and the slider 115. The connecting rod 121 drives the lifting block 123 to move upward under the action of the rotating shaft 122. The lifting block 123 drives the belt pulley assembly 101 to be pulled out along the outside of the double-twisting machine transmission shaft 100 under the action of the arc-shaped top plate 1251 through the grasping disc 125;

[0075] As Figures 5-6 shown, among them, in the present invention, a grasping disc 125 is used for transition between the relatively thin arc-shaped top plate 1251 and the lifting block 123, which improves the stiffness of the arc-shaped top plate 1251 and avoids bending deformation of the relatively thin arc-shaped top plate 1251 during the process of pulling the belt pulley assembly 101;

[0076] As Figure 5 shown, in addition, during the process of pulling out the relatively thick belt pulley assembly 101 from the outside of the double-twisting machine transmission shaft 100 in the present invention, since the contact area between the outside of the relatively thick belt pulley assembly 101 and the outside of the double-twisting machine transmission shaft 100 is relatively large, the frictional force between them and the double-twisting machine transmission shaft 100 is relatively large. Therefore, when pulling out this type of relatively thick belt pulley assembly 101 from the outside of the double-twisting machine transmission shaft 100, a relatively thick grasping block 124 is preferably used. The specific operation is to rotate the lifting block 123. The lifting block 123 drives the rotating shaft 122 to rotate within the receiving hole 1212, so that the lifting block 123 drives the grasping block 124 that was originally facing away from the belt pulley assembly 101 to switch to pointing to the belt pulley assembly 101, and the grasping disc 125 that was originally pointing to the belt pulley assembly 101 switches to facing away from the belt pulley assembly 101. Then, the relatively thick grasping block 124 is used to pull the belt pulley assembly 101 out from the outside of the double-twisting machine transmission shaft 100. The specific pulling-out process is the same as the above process of pulling out the belt pulley assembly 101 by using the arc-shaped top plate 1251, and will not be elaborated here, thereby prolonging the service life of the puller.
