[0027] The embodiments of the present application will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0028] As shown in Figs. 1-2 The embodiments of the present application provide a bushing dismounting device, which comprises:

[0029] The base 100 is provided with a stand 102;

[0030] The mounting seat 104 is mounted on the stand 102, and the mounting seat 104 is provided with a sliding block 106, and the sliding block 106 is connected with an air cylinder 108, and one end of the air cylinder 108 facing the base 100 is provided with a pressure head 110;

[0031] The handle 112 is rotatably connected to the mounting seat 104 and is in transmission connection with the sliding block 106.

[0032] According to the bushing dismounting device provided by the embodiment of the utility model, through mechanized operation, the bushing dismounting device can quickly and accurately complete the dismounting work of the bushing, greatly improving the work efficiency compared with the traditional manual dismounting mode. When a large number of bushings are dismounted, the air cylinder 108 can be used to drive the ram 110 to act, and when a small number of bushings are dismounted, the handle 112 can be manually operated to drive the ram 110 to dismount, that is, when the bushing is dismounted by using the device, the operator can flexibly select the dismounting mode of the bushing according to the actual dismounting requirements. Moreover, during the dismounting process, the operator does not need to directly contact the bushing and the installation environment of the bushing which are high in temperature or high in pressure, thereby reducing the safety risk in the working process. Since the sliding block 106 on the mounting seat 104 can be slid to adjust the position, and the air cylinder 108 and the ram 110 are flexibly designed, the device can adapt to the dismounting requirements of bushings of different sizes and types, thereby improving the versatility and practicality of the device. The position of the ram 110 can be controlled by rotating the handle 112, so that the whole dismounting process becomes simple and easy to understand, the operation difficulty is reduced, and the operation accuracy is improved. Therefore, the bushing dismounting device has the advantages of high efficiency, safety, strong adaptability and simple operation, and is suitable for various occasions where the bushing needs to be dismounted.

[0033] Please continue to see Figs. 1-2 The embodiment of the utility model aims at providing a bushing dismounting device which simplifies the dismounting process of the bushing through the mechanical mode and improves the dismounting efficiency and safety.

[0034] Specifically, the base 100 is the basic support structure of the whole device, and the base 100 is stably placed on the ground. On the base 100, the stand column 102 is arranged, which is used for supporting and fixing the mounting seat 104 above.

[0035] The mounting seat 104 is firmly mounted on the stand column 102 and has a certain adjustment space or fixed position to adapt to the requirements of different working environments. On the mounting seat 104, the sliding block 106 is arranged, and the sliding block 106 can slide in a certain direction on the mounting seat 104. This sliding design makes the ram 110 close to or away from the base 100 to adapt to the dismounting requirements of bushings of different sizes.

[0036] The air cylinder 108 is connected with the sliding block 106 in a certain mode (such as bolt connection, welding, etc.), so that the air cylinder 108 can move with the sliding block 106. The air cylinder 108 is provided with the ram 110 at one end facing the base 100, and the ram 110 is the part actually performing the dismounting action. When the air cylinder 108 is activated, it will generate a pushing force or a pulling force to push or pull the bushing out of the installation position through the ram 110.

[0037] The handle 112 is rotatably connected to the mounting seat 104 and is in transmission connection with the sliding block 106. This design allows the operator to drive the sliding block 106 to move by rotating the handle 112, thereby controlling the position of the pressing head 110. The rotation of the handle 112 can be converted into the linear motion of the sliding block 106, realizing the accurate control of the pressing head 110.

[0038] According to an embodiment of the present application, a sliding groove is formed on the mounting seat 104 in the height direction of the mounting seat 104, and the sliding block 106 is slidably connected to the sliding groove.

[0039] In the embodiment of the present application, a sliding groove is designed in the height direction of the mounting seat 104. This design enables the sliding block 106 to slide accurately and stably on the mounting seat 104. Specifically, the formation of the sliding groove ensures the free movement of the sliding block 106 in the vertical direction (i.e. the height direction), while limiting the deviation of the sliding block 106 in the horizontal direction, thereby ensuring the stability and accuracy of the pressing head 110 during disassembly.

[0040] The sliding block 106 is designed to match the shape of the sliding groove and is connected together by sliding fit. This design ensures that the sliding block 106 can move smoothly in the sliding groove, while reducing friction and wear.

[0041] In order to prevent the sliding block 106 from falling off or moving excessively during sliding, a limiting device can be provided at the end or key position of the sliding groove. These devices can be simple stop blocks, spring pins or other forms of locking mechanisms, which are used to fix the position of the sliding block 106 when needed.

[0042] The sliding fit design of the sliding groove and the sliding block 106 makes the entire disassembly device more stable during operation. Even in high load or complex working environment, the accurate position and stable movement of the pressing head 110 can be ensured. Since the sliding block 106 can move freely in the sliding groove, the position of the pressing head 110 can be easily adjusted as needed. This flexibility enables the device to adapt to the disassembly needs of different sizes and types of bushings, improving its practicality and universality. The movement of the sliding block 106 can be controlled by simply rotating the handle 112, thereby adjusting the position of the pressing head 110. This design simplifies the operation process, reduces the difficulty of operation, so that even non-professionals can easily get started. The sliding fit design of the sliding groove and the sliding block 106 reduces friction and wear, thereby prolonging the service life of the entire disassembly device. At the same time, the setting of the limiting device also prevents accidental damage of the sliding block 106 during sliding.

[0043] According to an embodiment of the present application, the mounting seat 104 is provided with a locking piece 114, and the mounting seat 104 is adapted to lock the relative position with the stand 102 through the locking piece 114.

[0044] In the embodiment of the utility model, locking piece 114 is additionally arranged on mounting seat 104, which makes mounting seat 104 firmly locked at a specific position on stand column 102. The introduction of locking piece 114 not only enhances the stability of the device, but also allows the operator to quickly and accurately adjust the position of mounting seat 104 when needed, and lock it at the required height, to adapt to different working environments and bushing disassembly requirements.

[0045] Locking piece 114 can adopt various locking methods, such as bolt locking, buckle locking, pin locking, etc. These locking methods can effectively fix mounting seat 104 on stand column 102, preventing it from moving or loosening during work.

[0046] The design of locking piece 114 allows the operator to easily adjust the position of mounting seat 104 when needed. Once the appropriate height is found, the operator only needs to lock mounting seat 104 on stand column 102 through locking piece 114. This adjustment flexibility makes the device adapt to different sizes and types of bushing disassembly requirements.

[0047] The introduction of locking piece 114 also improves the safety of the device. During disassembly, even if unexpected situations such as sudden loosening or ejection of the bushing occur, locking piece 114 can ensure that mounting seat 104 and pressure head 110 remain in place, preventing harm to the operator.

[0048] The design of locking piece 114 makes mounting seat 104 firmly locked on stand column 102, thereby improving the stability of the entire disassembly device. This helps to ensure the accurate position and stable movement of pressure head 110 during disassembly. The introduction of locking piece 114 allows the operator to easily adjust the position of mounting seat 104 according to actual needs and lock it at the required height. This adjustment flexibility makes the device adapt to different working environments and bushing disassembly requirements. The design of locking piece 114 not only enhances the stability of the device, but also improves safety. During disassembly, even if unexpected situations occur, locking piece 114 can ensure that mounting seat 104 and pressure head 110 remain in place, preventing harm to the operator. Through the setting of locking piece 114, the operator can more easily adjust the position of mounting seat 104 and lock it at the required height. This design simplifies the operation process, reduces the operation difficulty, and improves the work efficiency.

[0049] According to one embodiment of the utility model, a gas source is arranged on mounting seat 104, and the gas source is in fluid communication with air cylinder 108 through a pipeline assembly.

[0050] In the embodiment of the utility model, the air source is additionally arranged on the mounting seat 104, and the air source can be directly connected with the air cylinder 108 through the pipeline assembly. This improvement not only simplifies the structure of the device, but also improves the convenience and efficiency of operation.

[0051] The air source and the air cylinder 108 are connected through the pipeline assembly, and the pipeline assembly can include various pipes, joints, valves and other elements to ensure the smooth flow and accurate control of the gas.

[0052] The connection between the air source and the air cylinder 108 can be achieved in various ways, such as quick connector connection. These connection methods can effectively ensure the sealing and stability of the gas, preventing gas leakage or pressure loss.

[0053] By arranging the air source on the mounting seat 104 and directly connecting it with the air cylinder 108 through the pipeline assembly, the overall structure of the device is simplified. This design reduces the need for additional air source supply equipment and connection pipes 122, making the entire disassembly device more compact and portable. The direct connection between the air source and the air cylinder 108 allows the operator to more conveniently control the supply and stop of the gas, thereby achieving precise control of the pressure head 110. This design reduces the difficulty of operation and improves work efficiency. Since the air source is directly arranged on the mounting seat 104 and connected with the air cylinder 108 through the pipeline assembly, the loss and fluctuation during gas transmission are reduced. This helps to ensure the stable movement of the pressure head 110 during disassembly, improving the accuracy and reliability of disassembly.

[0054] According to one embodiment of the utility model, the pipeline assembly comprises:

[0055] The air inlet pipe 116 is connected between the outlet of the air source and the inlet of the air cylinder 108;

[0056] The air return pipe 118 is connected between the inlet of the air source and the outlet of the air cylinder 108.

[0057] In the embodiment of the utility model, the pipeline assembly is further divided into two parts, including the air inlet pipe 116 and the air return pipe 118, which makes the gas flow between the air source and the air cylinder 108 more efficient and controllable.

[0058] The air inlet pipe 116 is connected between the outlet of the air source and the inlet of the air cylinder 108, and is used to transport the compressed air or gas generated by the air source into the air cylinder 108. The design of the air inlet pipe 116 needs to ensure the smooth flow and sufficient pressure of the gas to meet the working requirements of the air cylinder 108.

[0059] The return air pipe 118 is connected between the inlet of the air source and the outlet of the air cylinder 108, for recycling and reintroducing the discharged gas in the air cylinder 108 into the air source. This design realizes the recycling of gas and improves the energy utilization efficiency. At the same time, the return air pipe 118 can also help balance the gas pressure between the air source and the air cylinder 108, ensuring the stable operation of the system.

[0060] By setting the air inlet pipe 116 and the return air pipe 118, the recycling of gas is realized, and the waste of gas is reduced. This helps to reduce energy consumption and environmental pollution, and improves the energy utilization efficiency of the entire disassembly device. The design of the return air pipe 118 helps to balance the gas pressure between the air source and the air cylinder 108, preventing system instability caused by pressure fluctuations. This stability is crucial for ensuring the accurate control of the pressure head 110 and the accuracy of disassembly. The setting of the air inlet pipe 116 and the return air pipe 118 makes the flow path of gas between the air source and the air cylinder 108 more clear and efficient. This helps to reduce the loss and resistance of gas in the transmission process, improving the operating efficiency of the entire system. Since the structure of the air inlet pipe 116 and the return air pipe 118 is relatively simple and easy to disassemble, in actual application, when the air source or the air cylinder 108 needs to be maintained or replaced, it can be more convenient to operate. This reduces maintenance costs and time costs. By setting the air inlet pipe 116 and the return air pipe 118, the orderly flow of gas in the system can be ensured, preventing safety hazards caused by gas leakage or accumulation. This helps to improve the safety of the entire disassembly device.

[0061] According to an embodiment of the present application, an oil-water separator 120 is further provided on at least one of the air inlet pipe 116 and the return air pipe 118.

[0062] In the embodiment of the present application, in order to further improve the purity of the gas and the stability of the system, an oil-water separator 120 is added to the air inlet pipe 116 and / or the return air pipe 118. This innovative design helps to remove oil and water from the gas, ensuring efficient and stable flow of gas in the system.

[0063] The oil-water separator 120 can be provided on the air inlet pipe 116 to remove oil and water from the gas before it enters the air cylinder 108; or it can be provided on the return air pipe 118 for purification treatment before the gas returns to the air source. According to actual needs, the oil-water separator 120 can also be provided on both the air inlet pipe 116 and the return air pipe 118 to achieve double purification effect.

[0064] The oil-water separator 120 separates oil and water from the gas by physical or chemical methods. For example, oil and water can be allowed to settle to the bottom of the separator by gravity, or impurities in the gas can be removed by adsorption, filtration, etc. The purified gas continues to flow along the pipeline, while the impurities such as oil and water are collected in the separator for subsequent processing or discharge.

[0065] The oil-water separator 120 helps to remove oil and water from the gas, ensuring efficient and stable circulation of the gas in the system. This helps to improve the control accuracy and disassembly accuracy of the pressure head 110. Impurities such as oil and water can cause corrosion and wear to components such as the air source and air cylinder 108, affecting the performance and lifespan of the equipment. By providing the oil-water separator 120, the damage to the equipment caused by these impurities can be reduced, extending the service life of the equipment. The purification effect of the oil-water separator 120 helps to maintain the cleanliness and dryness of the inside of the system, preventing system blockage or failure caused by oil and water accumulation. This helps to optimize the performance of the system and improve the operating efficiency of the entire disassembly device. Accumulation of impurities such as oil and water in the system can pose a safety hazard. By providing the oil-water separator 120, these impurities can be removed in a timely manner, reducing the risk of safety accidents.

[0066] According to an embodiment of the present application, the pipeline assembly further comprises a connecting pipe 122, the connecting pipe 122 being used to connect the air source and the air inlet pipe 116, and the oil-water separator 120 being connected between the connecting pipe 122 and the air inlet pipe 116.

[0067] In the embodiment of the present application, the pipeline assembly is further optimized by adding the key component of the connecting pipe 122, and the connection position of the oil-water separator 120 between the connecting pipe 122 and the air inlet pipe 116 is specified. This design makes the entire gas circulation system more perfect, ensuring efficient and stable circulation of the gas.

[0068] The connecting pipe 122 serves as a bridge between the air source and the air inlet pipe 116, playing a key connection role. It ensures that the gas generated by the air source can flow smoothly to the air inlet pipe 116 and then enter the air cylinder 108. The design of the connecting pipe 122 needs to consider factors such as the flow rate and pressure of the gas, as well as the material and size of the pipeline, to ensure stable operation of the system.

[0069] The oil-water separator 120 is connected between the connecting pipe 122 and the air inlet pipe 116, and is used to remove oil and water from the gas. This design allows the gas to be effectively purified before entering the air cylinder 108, improving the purity of the gas and the stability of the system. The working principle of the oil-water separator 120 is as described above, which separates impurities from the gas by physical or chemical methods, ensuring that the purified gas continues to flow along the pipeline.

[0070] The introduction of the connecting pipe 122 makes the connection between the gas source and the air inlet pipe 116 more tight and smooth, ensuring efficient circulation of the gas. At the same time, the oil-water separator 120 is also carefully designed at the connection position between the connecting pipe 122 and the air inlet pipe 116, making the entire gas circulation system more perfect. The oil-water separator 120 effectively removes impurities such as oil and water in the gas, improving the purity of the gas. This helps to reduce the damage of impurities to the gas source and the air cylinder 108 and other components, prolonging the service life of the equipment. At the same time, pure gas also helps to improve the stability and reliability of the system. The design of the connecting pipe 122 and the oil-water separator 120 makes the entire system more compact and efficient. This helps to reduce the energy consumption and emissions of the system, improving energy utilization efficiency. At the same time, the optimization of the system also helps to improve the efficiency and accuracy of the disassembly device.

[0071] According to an embodiment of the present application, the mounting seat 104 is provided with a control element 124, and the control element 124 is electrically connected with the gas source to control the opening and closing of the gas source.

[0072] In the embodiment of the present application, the control element 124 is additionally arranged on the mounting seat 104, which makes the opening and closing of the gas source more accurate and convenient to control.

[0073] The control element 124 is arranged on the mounting seat 104, which is not only convenient for operation but also can ensure the stability of control. The mounting seat 104 is the basic component of the entire device, and its stability and reliability are crucial for the operation of the entire system.

[0074] The control element 124 and the gas source are electrically connected, which makes the control signal quickly and accurately transmitted to the gas source, realizing accurate control of the gas source. The design of electrical connection needs to consider the transmission speed of signal, anti-interference ability and reliability of connection, etc., to ensure the stability and accuracy of control.

[0075] The main function of the control element 124 is to control the opening and closing of the gas source. By sending corresponding control signals to the control element 124, the opening or closing operation of the gas source can be realized. This function is crucial for ensuring the normal operation of the entire gas circulation system.

[0076] The introduction of the control member 124 makes the control of the gas source more accurate and reliable. Through electrical connection, rapid response and precise control of the gas source can be achieved, improving the stability and reliability of the entire system. The design of the control member 124 makes the operation of the gas source more convenient and simple. The operator only needs to send the corresponding control signal to the control member 124 to realize the opening or closing operation of the gas source, without complex mechanical operation or adjustment. The electrical connection design between the control member 124 and the gas source makes the system more secure. In an emergency, the gas source can be quickly turned off by sending an emergency stop signal to the control member 124 to prevent accidents.

[0077] According to an embodiment of the present application, the base 100 is provided with a positioning part 126 corresponding to the pressure head 110 for positioning the bushing.

[0078] In the embodiment of the present application, the positioning part 126 is added to the base 100, which is an innovative design to improve the positioning accuracy and stability of the bushing during disassembly.

[0079] The positioning part 126 is arranged on the base 100 corresponding to the position of the pressure head 110. This position selection ensures that the pressure head 110 can accurately contact the bushing when it is lowered and effectively disassemble it. At the same time, the design of the positioning part 126 also takes into account factors such as the size and shape of the bushing to ensure its matching degree and stability with the bushing.

[0080] The positioning part 126 is usually made of materials with certain rigidity and precision to ensure that it will not deform or be damaged during use. In addition, the shape and size of the positioning part 126 also need to match the bushing to ensure that it can effectively position the bushing.

[0081] The main function of the positioning part 126 is to ensure the positioning accuracy and stability of the bushing during disassembly. Through the contact and cooperation of the positioning part 126 and the bushing, the movement and rotation of the bushing during disassembly can be limited, so that the pressure head 110 can accurately act on the bushing to achieve effective disassembly.

[0082] The introduction of the positioning part 126 significantly improves the positioning accuracy of the bushing during disassembly. Through the precise fit of the positioning part 126 and the bushing, it can be ensured that the pressure head 110 can accurately act on the bushing, avoiding disassembly failure or damage due to inaccurate positioning. The design of the positioning part 126 makes the bushing more stable during disassembly. By limiting the movement and rotation of the bushing, it can be ensured that the pressure head 110 will not be affected by the instability of the bushing during disassembly, thereby improving the efficiency and accuracy of disassembly. The shape and size of the positioning part 126 can be customized according to the size and shape of the bushing to adapt to different types and specifications of bushings. This makes the device more adaptable and flexible when disassembling different bushings.

[0083] According to an embodiment of the present application, a universal joint is provided between the pressure head 110 and the air cylinder 108.

[0084] In the embodiment of the present application, a universal joint is added between the pressure head 110 and the air cylinder 108. This design aims to improve the flexibility and adaptability of the pressure head 110 during disassembly. The following is a detailed description of this embodiment:

[0085] The universal joint is arranged between the pressure head 110 and the air cylinder 108, which plays a role in connecting and transmitting power. This position selection ensures that the pressure head 110 can be flexibly adjusted in angle and position as needed during disassembly to adapt to bushings of different shapes and sizes.

[0086] The universal joint usually adopts a multi-joint design, and each joint can freely rotate within a certain range. This design allows the universal joint to maintain good flexibility and stability while transmitting power. In addition, the material of the universal joint also needs to have certain strength and wear resistance to ensure that it will not be damaged due to excessive stress during use.

[0087] Through the connection of the universal joint, the pressure head 110 can adjust the angle and position as needed during disassembly. This helps to ensure that the pressure head 110 can accurately act on the bushing, avoiding disassembly failure or damage due to improper angle or position. At the same time, the design of the universal joint also makes the pressure head 110 better adapt to the shape and size of the bushing during disassembly, improving the efficiency and accuracy of disassembly.

[0088] The introduction of the universal joint makes the pressure head 110 have higher flexibility during disassembly. By adjusting the angle and position of the universal joint, it can be ensured that the pressure head 110 can accurately act on the bushing regardless of the change in shape and size of the bushing. The design of the universal joint makes the device have stronger adaptability when disassembling bushings of different shapes and sizes. By adjusting the angle and position of the universal joint, it can be ensured that the pressure head 110 can always maintain good contact and cooperation with the bushing, improving the efficiency and accuracy of disassembly. Since the universal joint has a certain flexibility and buffering effect, it can reduce the wear and damage to the pressure head 110 and the bushing during disassembly. This helps to prolong the service life of the equipment and reduce maintenance costs.
