Abstract
Description
Technical Field
[0001] This application relates to the field of generator technology, and more specifically, to a tool for resetting the embedded nut of a vehicle generator. Background Technology
[0002] As a core component of fuel vehicles, the 12V alternator for vehicles is usually installed at the front end of the alternator and fastened to the side of the cylinder block by bolts and nuts. In order to improve assembly efficiency, the industry has gradually adopted interference fit, which directly embeds the mounting nut into the alternator mounting hole.
[0003] During the initial installation, no additional tools are needed to secure the nut; simply insert the bolt and tighten it. However, when the generator needs to be disassembled or repaired, the embedded nut will still protrude from the surface of the mounting bracket due to the interference fit, causing mechanical interference with the cylinder block mounting lugs and making secondary installation difficult. In this case, the mounting nut needs to be reset.
[0004] Existing methods for resetting mounting nuts include:
[0005] Hammering method: Use a thin rod to be angled against the edge of the nut and strike it with a hammer to reset it. This requires multiple strikes, which is time-consuming and laborious. Furthermore, repeated strikes to the generator bracket may cause it to break.
[0006] Clamping method: Use long pliers or table clamps to hold the nut, but the space inside the nut is narrow, the pliers cannot clamp effectively, and they are prone to wear and tear on the nut;
[0007] Bolt pulling method: This method requires finding a suitable bolt and shim on the spot, and pulling out the nut by using the reaction force. This method is time-saving, labor-saving and has no risk of damage, but it is difficult to find a bolt of suitable length and a shim of suitable thickness on the spot.
[0008] Therefore, there is an urgent need for a special pull-out and reset tool for the embedded nut of a vehicle generator. Utility Model Content
[0009] This application aims to address at least one of the technical problems existing in the prior art or related technologies.
[0010] Therefore, this application provides a tool for resetting the embedded nut of a vehicle generator, which can quickly reset the embedded nut and is simple and quick to operate.
[0011] The vehicle generator internal nut reset tool provided in this application includes a screw, a lever, and a pad. The screw passes through a first bracket through-hole of the generator, and the internal nut is located within the first bracket through-hole. The lever is detachably mounted on one end of the screw. The pad is located on the end of the screw away from the lever, and is positioned on a second bracket through-hole of the generator.
[0012] In some embodiments, the screw may further include: a first thread disposed in the middle of the screw and engaging with the internal thread of the embedded nut; and a second thread disposed at the end of the screw away from the force-applying rod.
[0013] In some embodiments, the pad includes: a gasket; a groove disposed on the gasket and the groove engaging with the end of the screw near the second thread; and a positioning boss disposed on the side of the gasket away from the groove and the positioning boss engaging with the second bracket through hole of the generator.
[0014] In some embodiments, the positioning boss has an internal thread that engages with the second thread.
[0015] In some embodiments, the gasket is made of nylon or POM.
[0016] In some embodiments, the pad is a one-piece structure.
[0017] In some embodiments, the first bracket through hole and the second bracket through hole are distributed along the same central axis.
[0018] In some embodiments, the surface of the extension rod has an anti-slip texture.
[0019] In some embodiments, the screw is made of alloy steel.
[0020] In some embodiments, the reset tool is T-shaped.
[0021] Compared with the prior art, the technical solution provided in this application includes at least the following technical effects:
[0022] This application provides a tool for resetting embedded nuts in vehicle generators, which can quickly and easily reset embedded nuts. A screw is inserted into the through hole of the first bracket of the generator and gradually screwed into the embedded nut located within that hole. Simultaneously, one end of the screw extends out of the first bracket through hole, gradually approaching the second bracket through hole. At this point, a pad is installed on the second bracket through hole, and a lever is installed on the other end of the screw. Depending on the reset direction of the embedded nut, the lever is turned clockwise or counterclockwise. The lever drives the screw to rotate, causing the end of the screw to gradually press against the pad. Upon further rotation, the screw no longer moves. The rotation of the screw then generates a reaction force on the embedded nut, causing it to move along the thread direction of the screw until it is flush with the inner end face of the first bracket, thus resetting the embedded nut.

[0030] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0031] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.
[0032] The following reference Figures 1 to 3 This application describes a tool for resetting the embedded nut of a vehicle generator according to some embodiments.
[0033] like Figure 1 As shown, a resetting tool for an embedded nut of a vehicle generator according to some embodiments of this application includes a screw 2, a lever 1, and a pad 3. The screw 2 passes through a first bracket through-hole 4 of the generator, and the embedded nut is located within the first bracket through-hole 4; the lever 1 is detachably mounted at one end of the screw 2; the pad 3 is mounted at the end of the screw 2 away from the lever 1, and the pad 3 is located on a second bracket through-hole 5 of the generator.
[0034] In this embodiment, the screw 2 is inserted into the first bracket through hole 4 of the generator and gradually screwed into the embedded nut located in the through hole. At the same time, one end of the screw 2 will extend out of the first bracket through hole 4, and the extended end will gradually approach the second bracket through hole 5. At this time, the pad 3 is installed on the second bracket through hole 5, and the force-adjusting rod 1 is installed on the other end of the screw 2. According to the reset direction of the embedded nut, the force-adjusting rod 1 is turned clockwise or counterclockwise. The force-adjusting rod 1 drives the screw 2 to rotate together, so that the end of the screw 2 gradually abuts against the pad 3. When rotated again, the screw 2 will no longer move. At this time, the rotation of the screw 2 will generate a reaction force on the embedded nut, so that the embedded nut moves along the thread direction of the screw 2 until it is flush with the inner end face of the first bracket, thus realizing the reset of the embedded nut.
[0035] In this design, the lever 1 utilizes the lever principle to increase the torque required to turn the screw 2. The operator can generate a large torque with a relatively small force to rotate the screw 2, thus easily resetting the embedded nut. Compared to traditional methods using other tools or manually tightening bolts, this reduces the operator's workload and improves work efficiency.
[0036] In some possible embodiments, such as Figure 2 As shown, it also includes: a first thread 21, which is located in the middle of the screw 2 and engages with the internal thread of the embedded nut; and a second thread 22, which is located at the end of the screw 2 away from the force-applying rod 1.
[0037] In this embodiment, the first thread 21 engages with the internal thread of the embedded nut to form a threaded connection. When the screw 2 rotates, the rotational motion is converted into the linear motion of the embedded nut through the engagement of the threads, causing the embedded nut to move. The second thread 22 engages with the pad 3 to accommodate the pad 3.
[0038] In some possible embodiments, such as Figure 3 As shown, the pad 3 includes: a pad 31; a groove disposed on the pad 31, and the groove engages with the end of the screw 2 near the second thread 22; and a positioning boss 32 disposed on the side of the pad 31 away from the groove, and the positioning boss 32 engages with the second bracket through hole 5 of the generator.
[0039] In this embodiment, the positioning boss 32 of the pad 3 is placed in the through hole 5 of the second bracket to position the pad 3 on the second bracket. At this time, the groove of the pad 3 faces the screw 2. During the rotation of the screw 2, its end is located in the groove, providing a clear radial constraint for the rotation of the screw 2, so that the screw 2 always stays on the predetermined axis of rotation. At the same time, when the screw 2 rotates into the groove of the pad 31, the groove forms an axial limit on the screw 2. When the screw 2 continues to rotate, since there is a threaded engagement between the screw 2 and the embedded nut, the rotation of the screw 2 will drive the embedded nut to rotate together. However, the embedded nut is embedded in the through hole 4 of the first bracket and cannot rotate freely. Therefore, when the screw 2 rotates, the embedded nut will move along the axial direction of the screw 2 to realize the reset action of the embedded nut.
[0040] In some possible embodiments, the positioning boss 32 has an internal thread that mates with the second thread 22.
[0041] In this embodiment, when the tool is not in use, the internal thread of the positioning boss 32 is engaged with the second thread 22 of the screw 2, that is, the pad 3 is stored on the screw 2, which avoids the loss and confusion caused by the scattered placement of the pad 3, and facilitates the next use.
[0042] In some possible embodiments, the gasket 31 is made of nylon or POM.
[0043] In this embodiment, the nylon and POM materials have high tensile strength and impact toughness, enabling the gasket 31 to withstand the torque force of the screw 2.
[0044] In some possible embodiments, such as Figure 2 As shown, pad 3 is a one-piece structure.
[0045] In this embodiment, the integrated structure means that the pad 3 is a continuous entity without any assembly marks between different parts. The integrated pad 3 can withstand a large load and will not suffer from performance degradation due to loose connections or fatigue fracture.
[0046] In some possible embodiments, as shown in the figure, the first bracket through hole 4 and the second bracket through hole 5 are distributed along the same central axis.
[0047] In this embodiment, after the screw 2 is inserted into the first bracket through hole 4 and the embedded nut is screwed in, one end of it will protrude out of the first bracket through hole 4. Since the axes of the two through holes are the same, the protruding end of the screw 2 can accurately approach the second bracket through hole 5 along the predetermined axial direction, providing a good prerequisite for the subsequent installation of the pad 3. If the axes of the two through holes do not coincide, the protruding end of the screw 2 may deviate from the position of the second bracket through hole 5, making it impossible to install the pad 3 smoothly. The position of the screw 2 needs to be readjusted, which increases the complexity and time cost of assembly.
[0048] In some possible embodiments, the surface of the extension bar 1 has an anti-slip texture.
[0049] In this embodiment, by adding anti-slip texture to the surface of the lever 1, the coefficient of friction between the hand and the lever 1 is increased, preventing slippage during use.
[0050] In some possible embodiments, the screw 2 is made of alloy steel.
[0051] In this embodiment, the alloy steel screw 2 has high rigidity, which enables the screw 2 to withstand large torque and tension, and is not prone to deformation or breakage.
[0052] In some possible embodiments, such as Figure 3 As shown, the reset tool is T-shaped.
[0053] In this embodiment, the T-shaped tool is composed of a vertical screw 2 and a horizontal force-applying rod 1 connected perpendicularly to each other. The force-applying rod 1 provides the operator with a wide gripping area. According to the lever principle, the longer the lever arm, the greater the torque generated when the applied force is constant. Therefore, the force-applying rod 1 is equivalent to the lever arm, which allows the operator to generate a large torque with a small force when using the T-shaped reset tool, and easily complete the reset operation.
[0054] When operating the generator internal nut reset tool, the screw 2 is inserted into the generator first bracket through hole 4, and gradually screwed into the internal nut located in the through hole. At this time, one end of the screw 2 extends out of the first bracket through hole 4 and gradually approaches the second bracket through hole 5. The pad 3 is installed on the second bracket through hole 5, that is, the positioning boss 32 of the pad 3 is embedded in its through hole to achieve positioning. At this time, the groove on the washer 31 faces the screw 2. The force rod 1 is installed on the other end of the screw 2. According to the reset direction of the internal nut, the force rod 1 is turned clockwise or counterclockwise. The force rod 1 uses the lever principle to drive the screw 2 to rotate together. The first thread 21 of the screw 2 and the internal thread of the internal nut cooperate with each other, converting the rotational motion into internal insertion. When the screw 2 rotates, the end of the screw 2 closest to the second thread 22 is located in the groove of the washer 31. The groove provides radial constraint for the rotation of the screw 2, keeping it on the predetermined axis of rotation. At the same time, it forms an axial limit on the screw 2. Since the embedded nut is embedded in the through hole 4 of the first bracket and cannot rotate freely, when the screw 2 continues to rotate, the embedded nut will move along the axis of the screw 2 through the thread engagement. Continue to tighten the lever 1 until the embedded nut is flush with the inner end face of the first bracket, thus realizing the reset of the embedded nut. At the same time, after the tool is used, the washer 3 is stored on the screw 2 by engaging the internal thread of the positioning boss 32 of the pad 3 with the second thread 22 of the screw 2 for easy use next time.
