Description

Technical Field

[0001] This utility model relates to the field of disassembly and assembly tools, and in particular to a disassembly and assembly tool for instruments and equipment. Background Technology

[0002] When performing routine maintenance work on instruments and equipment, equipment maintenance personnel often need to disassemble and install bearings of rotating mechanical equipment. Bearings are important components that fix and reduce the coefficient of friction during the rotation of instruments and equipment, which seriously affects the working stability of the instruments and equipment.

[0003] Currently, the traditional method for disassembling bearings is by tapping: a copper rod or other soft metal is placed on the inner ring of the bearing, and a hammer is used to gently tap it. After each tap, the bearing is moved to a different position so that the inner ring is subjected to a uniform force. This method is slow and the force is uneven. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for disassembling and assembling instruments and equipment, which aims to improve disassembly efficiency when disassembling bearings of instruments and equipment.

[0005] To achieve the above objectives, this utility model provides a tool for disassembling and assembling instruments and equipment, including a mounting plate and an adjustment mechanism;

[0006] The adjustment mechanism includes a slider, a threaded knob, a hexagonal rod, a pull rod, a plug-in plate, a rotating screw, and a guide device. The slider can slide within rectangular cavities on both sides of the mounting plate. The threaded knob is threadedly connected to the slider and abuts against the mounting plate, located at the top of the slider. The hexagonal rod is threadedly connected to the slider and located at the bottom of the slider. The pull rod is integrally formed with the hexagonal rod and located at the bottom of the hexagonal rod. The plug-in plate is integrally formed with the pull rod and located at the bottom of the pull rod. The rotating screw is threadedly connected to the mounting plate and passes through the mounting plate. The guide device is disposed on both sides of the slider.

[0007] The mounting plate is also provided with auxiliary threaded holes on both sides, which are connected to the rectangular cavity on the mounting plate on which the slider slides.

[0008] The guiding device includes a front guide rod and a rear guide rod. The front guide rod is threadedly connected to the slider and slidably connected to the mounting plate, and is located in front of the slider. The rear guide rod is threadedly connected to the slider and slidably connected to the mounting plate, and is located in rear of the slider.

[0009] The adjustment mechanism further includes a force-applying plate, which is detachably connected to the rotating screw and located at the top of the rotating screw.

[0010] The front working surface of the plug-in plate is provided with anti-slip texture.

[0011] This utility model discloses a tool for disassembling and assembling instruments and equipment. When using the tool, first loosen the threaded knob to release the slider and allow for position adjustment, thereby changing the position of the two connector plates. Then, snap the two connector plates onto the shaft, ensuring the working end face of the connector plate abuts against the inner and outer ring end faces of the bearing. Next, rotate the rotating screw, pressing its front tip against the center hole on the shaft end face, thus applying force to the connector plates. Then, tighten the threaded knob. Further, continue rotating the rotating screw using a wrench. The rotation of the rotating screw, in conjunction with the movement of the connector plates, achieves bearing disassembly. This application allows for disassembly without hammering the bearing, and is faster than hammering disassembly, thus improving disassembly efficiency when disassembling bearings in instruments and equipment.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Example 1:

[0019] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the tools used for disassembling and assembling instruments and equipment. Figure 2This is a schematic diagram of the slider 102. This utility model provides a tool for disassembling and assembling instruments and equipment: it includes a mounting plate 101 and an adjustment mechanism. The adjustment mechanism includes a slider 102, a threaded knob 103, a hexagonal rod 104, a pull rod 105, a plug-in plate 106, a rotating screw 107, a force-applying plate 110, and a guide device. The guide device includes a front guide rod 108 and a rear guide rod 109. The aforementioned solution can improve disassembly efficiency when removing bearings from instruments and equipment. It is understood that the aforementioned solution can improve disassembly efficiency.

[0020] In this embodiment, the mounting plate 101 has symmetrical rectangular cavities on both sides and a through threaded hole on the vertical center line.

[0021] The slider 102 can slide within the rectangular cavities on both sides of the mounting plate 101. The threaded knob 103 is threadedly connected to the slider 102 and abuts against the mounting plate 101, located at the top of the slider 102. The hexagonal rod 104 is threadedly connected to the slider 102 and located at the bottom of the slider 102. The pull rod 105 is integrally formed with the hexagonal rod 104 and located at the bottom of the hexagonal rod 104. The plug plate 106 is integrally formed with the pull rod 105 and located at the bottom of the pull rod 105. The rotating screw 107 is threadedly connected to the mounting plate 101 and passes through the mounting plate 101. The guide device is disposed on both sides of the slider 102. The rectangular end of the slider 102 can slide within the rectangular grooves on both sides of the mounting plate 101. The top of the slider 102 is an externally threaded end, facilitating the installation of the threaded knob 103. The bottom of the slider 102 is provided with a threaded hole, facilitating the installation of the hexagonal rod 104. The hexagonal rod 104 is provided with an external hexagonal snap-fit ​​part, facilitating the rotation and installation of the wrench. The top of the pull rod 105 is integrally formed with the hexagonal rod 104 to ensure stability. At the same time, the bottom of the pull rod 105 is integrally formed with the insertion plate 106, which is provided with a U-shaped snap-fit ​​groove, facilitating snap-fit ​​onto the outside of the shaft. The top of the rotating screw 107 is an external hexagonal part, facilitating rotation, and the bottom is a center point structure, facilitating engagement with the center hole on the shaft end face. The guiding device is used to guide the slider 102 when adjusting its sliding position, and can also form a limiting structure to improve the stability of the slider 102.

[0022] Secondly, auxiliary threaded holes are provided on both sides of the mounting plate 101, which communicate with the rectangular cavity on the mounting plate 101 where the slider 102 slides. The purpose of this structure is that after the slider 102 is adjusted and the plug plate 106 is engaged with the shaft, a screw can be directly installed in the threaded hole, so that the head of the screw can abut against the end face of the slider 102 for limiting engagement. When adjusting the position of the slider 102, the screw needs to be loosened in advance.

[0023] Then, the front guide rod 108 is threadedly connected to the slider 102 and slidably connected to the mounting plate 101, and is located on the front side of the slider 102; the rear guide rod 109 is threadedly connected to the slider 102 and slidably connected to the mounting plate 101, and is located on the rear side of the slider 102. The front guide rod 108 and the rear guide rod 109 have the same dimensions. The front external thread end can be directly installed and engaged with the threaded hole on the slider 102, and its optical axis end slides in the guide groove on the mounting plate 101. After the front guide rod 108 and the rear guide rod 109 are installed, they limit the slider 102, which facilitates the stable contact of its bottom rectangular limiting part with the bottom plane of the mounting plate 101.

[0024] Finally, the force-applying plate 110 is detachably connected to the rotating screw 107 and is located on top of the rotating screw 107. The force-applying plate 110 has a hexagonal cavity, which facilitates direct insertion into the outer hexagonal part at the top of the rotating screw 107. The rotating screw 107 can then be rotated via the force-applying plate 110. Compared to using a fixed-end wrench or adjustable wrench to rotate the rotating screw 107, there will be no slippage, making the rotation operation more stable.

[0025] When using this utility model to disassemble bearings in instruments and equipment, disassembly efficiency can be improved. When using the tool, first loosen the threaded knob 103 to release the slider 102 for position adjustment, thereby changing the position of the two insertion plates 106. Then, respectively, snap the two insertion plates 106 onto the shaft, ensuring that the working end face of the insertion plate 106 abuts against the inner and outer ring end faces of the bearing. Next, rotate the rotating screw 107, pressing its front tip against the center hole on the shaft end face, thus applying force to the insertion plates 106. Then, tighten the threaded knob 103. Further... The rotating screw 107 is rotated further using a wrench or the force plate 110. The bearing is disassembled by the rotation of the rotating screw 107 and the movement of the plug plate 106. This application does not require hammering the bearing for disassembly, and it is faster than hammering. The working end of the U-shaped cavity on the front side of the plug plate 106 can be set to different sizes. The upper side is respectively provided with the hexagonal rod 104 and the pull rod 105 to cooperate with the slider 102. When replacing, the hexagonal rod 104 can be directly removed and then replaced with a different size, thereby improving the disassembly efficiency when disassembling the bearings of instruments and equipment.

[0026] Example 2:

[0027] like Figure 3 As shown, where Figure 3 This is a schematic diagram of the overall structure of the disassembly and assembly tool for instruments and equipment. Based on the first embodiment, this utility model provides a disassembly and assembly tool for instruments and equipment, wherein the front working surface of the plug-in plate 106 is provided with anti-slip texture 201.

[0028] In this embodiment, by providing anti-slip texture 201 on the front working surface of the plug plate 106, the stability of the plug plate 106 when it mates with the inner and outer ring end faces of the bearing can be improved.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
