Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary machinery and equipment for spinning production, specifically to a pneumatic stamping and disassembly machine for an anti-twist device and roller shaft assembly. Background Technology
[0002] In the routine maintenance work of the chemical fiber industry, the replacement and repair of roller shafts and anti-twist bearings generally adopts traditional manual operation methods. The specific process involves two maintenance personnel working together: one removes the roller shaft and fixes it in a bench vise, while the other uses a punch and hammer to strike the roller shaft pin to knock it out, thus enabling subsequent bearing replacement and repair. Each step requires a significant amount of time and manpower. Especially when dealing with a large number of roller shafts and anti-twist bearings requiring replacement and repair, this inefficient maintenance method severely impacts equipment uptime, leading to production stoppages and significantly hindering the company's production efficiency and capacity improvement. Furthermore, using a hammer and punch for striking can result in the hammer deviating from the punch if not handled properly, causing hand injuries to the maintenance personnel. Traditional methods for replacing and repairing roller shafts and anti-twist bearings can no longer meet the demands of modern production. To improve maintenance efficiency, reduce labor intensity, ensure the safety of maintenance personnel, and enhance the overall performance of equipment, there is an urgent need to develop a more efficient, safe, and reliable maintenance technology and equipment to adapt to the ever-evolving needs of the chemical fiber industry. Summary of the Invention
[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a pneumatic stamping disassembly machine for anti-twist device and roller shaft assembly, which can solve the problem of difficult disassembly of components in anti-twist device and roller shaft, with simple structure and easy operation.
[0004] To solve the aforementioned technical problems, this application adopts the following technical solution:
[0005] A pneumatic stamping disassembly machine for an anti-twist device and roller shaft assembly is characterized by comprising a frame, a lifting cylinder mounted on the frame, a disassembly ejector pin mounted on the piston rod of the lifting cylinder, a mold mounted on the frame for fixing the product to be disassembled, and a control button mounted on one side of the frame. The disassembly ejector pin is detachably connected to the piston rod of the lifting cylinder. The anti-twist device or roller shaft of the assembly to be disassembled is fixed by the mold. The disassembly ejector pin, activated by the control button, extends the piston rod of the lifting cylinder downwards to eject and disassemble the assembly to be disassembled from the anti-twist device or roller shaft.
[0006] Preferably, the mold is provided with a first positioning seat for fixing the anti-twist device and a second positioning seat for fixing the roller shaft.

[0017] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0018] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0019] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0020] like Figure 1 and Figure 2 As shown, a pneumatic stamping disassembly machine for an anti-twist device and roller shaft assembly includes a frame 16, a lifting cylinder 10 mounted on the frame 16, a disassembly ejector pin 9 mounted on the piston rod of the lifting cylinder 10, a mold mounted on the frame 16 for fixing the product to be disassembled, and a control button 17 mounted on one side of the frame 16. The disassembly ejector pin 9 is detachably connected to the piston rod of the lifting cylinder 10. The anti-twist device or roller shaft of the assembly to be disassembled is fixed by the mold. The disassembly ejector pin 9, through the control button 17, activates the piston rod of the lifting cylinder 10 to extend downwards and eject the assembly to be disassembled from the anti-twist device or roller shaft.
[0021] In practical application, firstly, different disassembly ejector pins 9 are replaced according to different products. Then, the anti-twist device or roller shaft to be disassembled is placed on the mold and fixed. After starting the control button 17, the piston rod of the lifting cylinder 10 extends downward, causing the disassembly ejector pin 9 to press against the component to be disassembled and push it downward, thereby ejecting the bearing component in the anti-twist device or the pin in the roller shaft. During operation, it is no longer necessary to disassemble by manual knocking or other means, and the disassembly difficulty is lower. Especially when disassembling the pin in the roller shaft, it effectively solves the problem of the existing roller shaft being difficult to fix, which leads to the trouble of knocking out the pin.
[0022] A further improvement is that the mold is provided with a first positioning seat 11 for fixing the anti-twist device and a second positioning seat 14 for fixing the roller shaft. The first positioning seat 11 is provided with an upwardly protruding L-shaped backrest 8, and the second positioning seat 14 is provided with a plurality of limiting grooves 12. Both the first positioning seat 11 and the second positioning seat 14 are provided with a feeding hole 13.
[0023] The first positioning seat 11 is a planar support structure with an upwardly protruding L-shaped support 8 on it. To fix the anti-twist device, simply place it on the first positioning seat 11, ensuring that both sides of the anti-twist device are aligned with the L-shaped support 8. At this point, the bearing to be disassembled in the middle of the anti-twist device is directly above the discharge hole 13. When the disassembly pin 9 extends downward under the control of the lifting cylinder 10, it can press the bearing to be disassembled out of the anti-twist device and drop it directly into the discharge hole 13, thus achieving disassembly. When disassembling the component to be disassembled in the roller shaft, the roller shaft is limited by multiple matching limiting grooves 12, so that the pin to be disassembled is vertically upward. Then, the disassembly pin 9 extends downward under the control of the lifting cylinder 10, pressing the pin to be disassembled out of the pin hole of the roller shaft and dropping it directly into the discharge hole 13, thus achieving disassembly. Meanwhile, the mold is equipped with a first positioning seat 11 for fixing the anti-twist device and a second positioning seat 14 for fixing the roller shaft, which can realize the positioning of two products through one mold, thus making the mold more efficient and more convenient when disassembling different products.
[0024] A further improvement is made by providing a switching mechanism 3 between the frame 16 and the mold, through which the positions of the first positioning seat 11 and the second positioning seat 14 are quickly switched.
[0025] Since the mold is equipped with a first positioning seat 11 for fixing the anti-twist device and a second positioning seat 14 for fixing the roller shaft, the conventional movement method is prone to causing trouble. Therefore, a switching mechanism 3 is added between the frame 16 and the mold. The relative positions of the first positioning seat 11 and the second positioning seat 14 can be quickly switched through the switching mechanism 3, thereby reducing the difficulty of operation.
[0026] A further improvement is made to the switching mechanism 3, which includes a slide rail 1 on the frame 16, two positioning protrusions 6 on one side of the mold, and a positioning bolt 4 with one end threaded to the frame 16. Each of the two positioning protrusions 6 is provided with a U-shaped groove 5, and the openings of the two U-shaped grooves 5 are arranged opposite to each other.
[0027] The bottom of the mold is slidably mounted on the slide rail 1, and the positions of the positioning bolt 4 and the two U-shaped slots 5 are exactly the precise positions of the first positioning seat 11 and the second positioning seat 14. When quickly switching the relative positions of the first positioning seat 11 and the second positioning seat 14, simply move the mold laterally along the slide rail 1 until the U-shaped slot 5 of one of the positioning protrusions 6 is outside the positioning bolt 4 and is stopped by the positioning bolt 4. Then tighten the positioning bolt 4 to achieve precise position fixation. The operation is more convenient when positioning the first positioning seat 11 and the second positioning seat 14. Moreover, since the openings of the two U-shaped slots 5 are set opposite each other, when switching positions, it is not necessary to disassemble the entire positioning bolt 4. Simply loosen it to achieve sliding and switching, which reduces the difficulty of operation and increases the switching efficiency.
[0028] A further improvement is that the front side of the frame 16 is provided with a drawer 2, the top of the frame 16 is provided with a through hole 18, and the unloading hole 13 in the disassembly state is coaxially arranged with the through hole 18.
[0029] When the component to be disassembled is pushed downward by the disassembly pin 9, it can fall directly into the drawer 2 along the feed hole 13 and the through hole 18 for storage, thus effectively avoiding the problem of the component to be disassembled scattering, and making it more convenient to store the component to be disassembled.
[0030] A further improvement is that the frame 16 is provided with two control buttons 17, which are located on the front sides of the frame 16 respectively.
[0031] When unloading, both control buttons 17 must be installed simultaneously to activate the control cylinder, which can effectively improve the safety of operation and avoid accidental activation that could lead to a safety accident.
[0032] A further improvement is that a pin bracket 15 is provided on one side of the frame 16.
[0033] Since different products need to be disassembled, at least two types of disassembly pins 9 are required. Therefore, in order to avoid difficulty in quickly finding the disassembly pins 9 when needed, several pin brackets 15 are installed on one side of the frame 16. Spare disassembly pins 9 can be placed through the pin brackets 15.
[0034] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
