Description

Technical Field

[0001] The utility model relates to the field of tooling and provides an inner nesting and disassembly device. Background Art

[0002] In the prior art, the cover plate and the copper sleeve are usually installed by a press to form an interference fit, ensuring that the copper sleeve is completely and tightly fitted to the bottom hole. However, when the copper sleeve needs to be replaced, a tap is usually used to tap the inner hole of the copper sleeve, and the tightening force generated by the thread is used to try to remove it from the cover plate. This method has many problems. For example, due to improper tapping operation (such as non-vertical tapping), the copper sleeve may be deformed, thereby getting stuck with the cover plate and unable to be removed smoothly. To solve this problem, operators often need to use manual grinding, which not only consumes a lot of time and manpower, but also increases the risk of damaging the cover plate, resulting in material scrapping, which greatly affects work efficiency.

DETAILED DESCRIPTION

[0025] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figures 1 to 5 As shown, the embodiment of the present invention provides an inner nesting disassembly device, comprising:

[0027] A first fixing base 100 is used to mount a mounting plate 102. A first through hole 104 is formed on the fixing base. A first stopper 106 is also provided on the first fixing base 100 for fixing the mounting plate 102.

[0028] The second fixing seat 108 has a second through hole 110 formed on the second fixing seat 108 at a position corresponding to the first through hole 104. A tap fixing member 112 for fixing the tap is provided in the second through hole 110. A second limiting member 114 is further provided on the second fixing seat 108 along the radial direction of the second through hole 110. When the inner nest 128 enters the second through hole 110, the second limiting member 114 is used to clamp the inner nest 128.

[0029] According to the inner nest disassembly device provided in the embodiment of the present invention, by designing a special disassembly device, the disassembly process of the inner nest 128 is made more standardized and mechanized, avoiding the problems of low efficiency and complicated operation that may occur in the traditional manual disassembly method. The design of the limiter and the fixing part ensures the stability of the inner nest 128 and the tap during the disassembly process, and avoids safety accidents caused by improper operation or equipment failure. The use of this device for inner nest disassembly can reduce the dependence on professional disassembly tools and reduce the disassembly cost. At the same time, since the disassembly process is more standardized, the risk of damage to the inner nest 128 or damage to the equipment due to improper operation is also reduced, further reducing maintenance costs. Through the precise through-hole design and limiter clamping, the stability of the position and posture of the inner nest 128 during the disassembly process is ensured, and the accuracy and reliability of the disassembly are improved.

[0030] like Figures 1 to 5 As shown, the inner nesting and disassembly device provided by the embodiment of the present invention mainly consists of two parts: a first fixing seat 100 and a second fixing seat 108 .

[0031] The first fixing base 100 is used to mount the mounting plate 102, providing a stable support base for the entire disassembly device. A first through-hole 104 is defined in the first fixing base 100, designed to allow the inner nest 128 to pass through. Furthermore, a first retaining member 106 is provided on the first fixing base 100. This retaining member 106 primarily secures the mounting plate 102, preventing it from moving or falling off during operation.

[0032] The second fixing seat 108 cooperates with the first fixing seat 100 to jointly complete the removal of the inner nest 128. A second through-hole 110 is defined on the second fixing seat 108 at a position corresponding to the first through-hole 104. The size and shape of the second through-hole 110 match the tap holder 112 of the inner nest 128, allowing the tap holder 112 to smoothly enter the inner nest 128. The tap holder 112 is used to secure the tap, which plays a key role in the removal process. Rotating the tap generates sufficient force to remove the inner nest 128. Furthermore, a second retaining member 114 is provided on the second fixing seat 108 along the radial direction of the second through-hole 110. Once the inner nest 128 enters the second through-hole 110, the second retaining member 114 clamps the inner nest 128 into the second through-hole 110, preventing it from sliding or falling out during the removal process, thereby ensuring a smooth removal process.

[0033] According to an embodiment of the present invention, a relief groove 116 is defined on the first fixing seat 100 , and the first through hole 104 passes through the relief groove 116 .

[0034] In the embodiment of the present invention, an avoidance groove 116 is formed on the first fixing seat 100 , and the first through hole 104 passes through the avoidance groove 116 .

[0035] The purpose of the avoidance groove 116 is to provide enough space for the protruding structure of the inner nest 128 to be installed on the mounting plate 102 during the disassembly process.

[0036] The design of the first through hole 104 passing through the avoidance groove 116 ensures that the inner nest 128 can pass through the first fixing seat 100 smoothly and without any obstruction during the disassembly process. This design not only improves the disassembly efficiency, but also ensures a smooth disassembly process.

[0037] By designing the avoidance groove 116 and extending the first through-hole 104 therethrough, a smoother and more direct removal path is provided for the inner nest 128. This helps reduce friction and resistance during the removal process, thereby lowering the risk of damage to the inner nest 128 and the removal tools. This design makes the disassembly process simpler and more intuitive, reducing operational difficulty. Even non-professionals can more easily master the disassembly techniques, thereby improving the overall user experience.

[0038] According to an embodiment of the present invention, a locking hole 118 is defined on the first fixing base 100 , and the first limiting member 106 is detachably mounted in the locking hole 118 . The first limiting member 106 is used to limit the rotation of the mounting plate 102 relative to the first fixing base 100 .

[0039] In the embodiment of the present invention, a locking hole 118 is provided on the first fixing seat 100 , and a detachable first limiting member 106 is designed. The first limiting member 106 can be installed in the locking hole 118 .

[0040] The locking hole 118 is a specific hole formed on the first fixing base 100 for mounting and securing the first retaining member 106. The position and size of this hole are precisely designed based on the size and shape of the first retaining member 106 to ensure that the first retaining member 106 can be stably mounted on the first fixing base 100.

[0041] The first limiting member 106 is a detachable component used to limit the rotation of the mounting plate 102 relative to the first fixing base 100 .

[0042] During the installation process, the operator only needs to insert the first limiting member 106 into the locking hole 118 and fix it on the first fixing base 100 by an appropriate fastening method.

[0043] The limiting effect of the first limiter 106 on the mounting plate 102 can prevent the mounting plate 102 from rotating during the disassembly process due to excessive force or improper operation, thereby improving the stability of the disassembly device. The first limiter 106 adopts a detachable design, making the disassembly device more convenient when maintaining and replacing parts. The operator only needs to simply remove the first limiter 106 to perform necessary maintenance and maintenance on the disassembly device. Since the first limiter 106 can stably limit the rotation of the mounting plate 102, the additional workload caused by the rotation of the mounting plate 102 can be reduced during the disassembly process, thereby improving the disassembly efficiency. The precisely designed locking hole 118 and the first limiter 106 can ensure that the disassembly device can still maintain a good working condition during long-term use, thereby enhancing the reliability of the disassembly device.

[0044] According to an embodiment of the present invention, a third fixing seat 120 is further included. A pressing member 122 is rotatably mounted on the third fixing seat 120 . The pressing member 122 is used to press the mounting plate 102 to make the mounting plate 102 fit against the first fixing seat 100 .

[0045] In the embodiment of the present invention, the third fixing base 120 serves as a support and installation base and has sufficient stability and rigidity to ensure that the components installed thereon can work normally.

[0046] The pressing member 122 is rotatably mounted on the third fixing seat 120 , which means that the pressing member 122 can rotate around its own axis. The main function of the pressing member 122 is to press the mounting plate 102 so that it can fit tightly on the first fixing seat 100 .

[0047] The first fixing base 100 is the target to which the mounting plate 102 needs to be attached. The first fixing base 100 also needs to have sufficient stability and rigidity to ensure that the overall structure after being combined with the mounting plate 102 can work normally.

[0048] By combining the third fixing seat 120, the retaining member 122 and the mounting plate 102, a tight and stable structure can be formed, thereby improving the stability and reliability of the entire device or mechanism. The rotatable design of the retaining member 122 makes it easier to install and remove the mounting plate 102. It can be applied to various scenarios where the mounting plate 102 needs to be fitted and fixed, and has a wide range of applicability. At the same time, by adjusting the rotation angle and force of the retaining member 122, it can adapt to mounting plates 102 of different sizes and shapes, further enhancing its flexibility. When the mounting plate 102 fits tightly on the first fixing seat 100, it can effectively protect the components or areas below it from the influence of the external environment, such as dust, moisture, etc. This is of great significance for improving the service life and performance of the entire device or mechanism.

[0049] According to an embodiment of the present invention, a locking member 124 is provided on the second fixing seat 108 , and the tap fixing member 112 is adapted to be locked relative to the second fixing seat 108 by the locking member 124 .

[0050] In the embodiment of the present invention, a locking member 124 is provided on the second fixing seat 108 , and the tap fixing member 112 can be locked in relative position to the second fixing seat 108 by the locking member 124 .

[0051] As a part of the entire disassembling device, the second fixing base 108 provides a stable foundation for installing and supporting the tap fixing member 112 and other related components.

[0052] The locking member 124 is mounted on the second fixing base 108 and is used to secure the tap holder 112 in place. The design of the locking member 124 can be selected based on actual needs, and can include, for example, a screw, a clip, or a pin. Its primary function is to prevent the tap holder 112 from moving or falling out during disassembly due to excessive force or improper operation.

[0053] The tap holder 112 is a component used to secure the tap. It can be securely mounted on the second fixing base 108 by cooperating with the locking member 124. The design of the tap holder 112 must take into account the shape and size of the tap, as well as the stress conditions during disassembly, to ensure that the tap can operate stably.

[0054] The locking member 124 securely locks the tap holder 112 and the second fixing seat 108 relative to each other. This means that during the disassembly process, the tap holder 112 will not move or deflect due to excessive force or improper operation, thereby ensuring the stability and accuracy of the disassembly process.

[0055] The locking member 124 securely secures the tap holder 112 to the second mounting base 108, ensuring that the tap will not move or fall off due to excessive force or improper operation during the disassembly process, thereby improving the stability of the disassembly process. The design of the locking member 124 securely locks the relative position of the tap holder 112 to the second mounting base 108, helping to reduce the risk of disassembly failure or equipment damage caused by loose or falling components, thereby enhancing the reliability of the disassembly device. The locking member 124 is generally simple and easy to operate, making it easier for operators to adjust the position and angle of the tap holder 112 during disassembly and facilitating maintenance and repair of the disassembly device. Because the locking member 124 securely secures the tap holder 112, it reduces the additional workload caused by component movement or falling off during disassembly, thereby improving disassembly efficiency.

[0056] According to an embodiment of the present invention, the locking member 124 is disposed along the radial direction of the second through hole 110 .

[0057] In the embodiment of the present invention, the locking member 124 is a device capable of generating a radial locking force.

[0058] The locking member 124 is arranged radially to make more efficient use of space and generate a greater locking force. This is because radial locking can generally provide a more uniform force distribution, reducing stress concentration and component deformation caused by axial locking. Radial locking can ensure that the locked components are firmly supported in multiple directions, thereby improving overall stability. This helps to reduce failures or accidents caused by loose or falling components. Radial locking is generally easier to install and disassemble quickly. For example, when using locking elements such as screws or clips, locking or releasing can be achieved by simply rotating or pushing. This helps to improve work efficiency and reduce operational difficulty. Since radial locking generally does not require precise axial positioning of components, it can make it easier to achieve component interchangeability. This helps to reduce production costs and improve the flexibility and adaptability of equipment.

[0059] According to an embodiment of the present invention, there are at least two second limiting members 114 , and the at least two second limiting members 114 are symmetrically arranged along the axis of the second through hole 110 .

[0060] In the embodiment of the present invention, there are at least two second limiting members 114 , and the two (or more) second limiting members 114 are symmetrically arranged along the axis of the second through hole 110 .

[0061] In this embodiment, there are at least two second limiting members 114. This means that when the position of the inner nest 128 in the second through hole 110 needs to be limited or fixed, at least two limiting points will function simultaneously.

[0062] At least two second limiting members 114 are symmetrically arranged along the axis of the second through hole 110. This symmetrical layout not only helps to maintain the balance and stability of the entire structure, but also ensures that the limited components can be evenly distributed when subjected to force, avoiding excessive stress concentration.

[0063] Because the second stoppers 114 are symmetrically arranged along the axis of the second through-hole 110, this layout more effectively resists external forces or torque, thereby improving the stability of the entire structure. The simultaneous action of at least two second stoppers 114 more reliably limits the position of the inner nest 128 within the second through-hole 110, preventing it from accidentally moving or falling out. The symmetrical arrangement of the second stoppers 114 ensures that stresses applied to the inner nest 128 are evenly distributed, avoiding excessive stress concentration and thus extending the service life of the component.

[0064] According to an embodiment of the present invention, a base 126 is further included, and the first fixing base 100 and the second fixing base 108 are detachably disposed on the base 126 .

[0065] In the embodiment of the present invention, the base 126 serves as the supporting foundation of the entire structure. The base 126 should be designed to be strong enough to support other components mounted thereon. The material and shape of the base 126 can be customized according to the specific application scenario.

[0066] The first fixing seat 100 can be detachably connected to the base 126 by means of bolts, buckles or other fasteners.

[0067] The second fixing base 108 is similar to the first fixing base 100 , and the second fixing base 108 can also be detachably connected to the base 126 using the aforementioned connection method.

[0068] Because the first and second mounting brackets 100, 108 are detachably mounted on the base 126, users can easily replace or adjust the position and number of these brackets based on actual needs. This flexibility makes the structure adaptable to a variety of different application scenarios. The detachable design makes it easier for users to maintain and replace individual components. For example, if a bracket becomes damaged or needs to be upgraded, the user can easily remove it and replace it with a new one without having to replace the entire structure.

[0069] According to one embodiment of the present invention, along the length direction of the base 126 , the position of at least one of the first fixing base 100 and the second fixing base 108 relative to the base 126 is adjustable.

[0070] In the embodiment of the present invention, along the length direction of the base 126 , the position of at least one of the first fixing base 100 and the second fixing base 108 relative to the base 126 is adjustable.

[0071] The base 126 serves as a support and reference for the entire structure, and provides a stable foundation. The length direction of the base 126 is a reference for determining the position adjustment direction of the first fixing base 100 and the second fixing base 108.

[0072] The position of the first fixing base 100 relative to the base 126 is adjustable, which means that it can be moved along the length of the base 126 to adapt to different needs.

[0073] The position of the second fixing base 108 can be fixed or adjustable, depending on the needs of the actual application. If the position of the second fixing base 108 is also adjustable, then the second fixing base 108 can also move along the length direction of the base 126.

[0074] In order to achieve position adjustment of the first fixing base 100 and / or the second fixing base 108 relative to the base 126, various mechanisms may be used, for example:

[0075] Slide rail and slider mechanism: A slide rail is installed on the base 126, and the first fixed seat 100 and / or the second fixed seat 108 cooperates with the slide rail through the slider to achieve position adjustment.

[0076] Thread adjustment mechanism: By rotating the threaded rod, the first fixing base 100 and / or the second fixing base 108 can be pushed to move along the length direction of the base 126.

[0077] The position of the first fixing seat 100 and / or the second fixing seat 108 relative to the base 126 is adjustable, making the entire structure more flexible and adaptable to different application scenarios and needs. For example, when it is necessary to adjust the distance between the two fixing seats, it is only necessary to simply move one or both of the fixing seats. This technical solution enables the structure to adapt to different working environments and conditions more easily. For example, when it is necessary to fix components of different sizes or shapes, the position of the fixing seat can be adjusted to ensure the best fixing effect. The position adjustment mechanism is usually designed to be relatively simple and easy to operate, so that the user can easily make adjustments without the need for complex tools or professional knowledge. By precisely adjusting the position of the fixing seat, the fixed position of the component can be ensured to be more accurate, thereby improving the accuracy and reliability of the entire structure.

[0078] According to one embodiment of the present invention, the first through hole 104 and the second through hole 110 are coaxially arranged.

[0079] In the embodiment of the present invention, the first through hole 104 and the second through hole 110 are coaxially arranged.

[0080] The coaxial arrangement ensures that the two through-holes are on the same axis in space, thereby allowing the inner nest 128 to maintain a straight line movement when passing through, reducing the risk of friction, distortion or damage.

[0081] Because first through-hole 104 and second through-hole 110 are coaxially arranged, inner nest 128 can pass through smoothly and unimpeded, reducing resistance or friction caused by misaligned through-holes. This coaxial arrangement ensures accuracy and precision when inner nest 128 passes through the two through-holes, avoiding misalignment or failure caused by deviation.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
