[0028] To enable those skilled in the art to better understand the solution of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.
[0029] The embodiment of the present application provides a generator torque detection auxiliary tool, which can solve the technical problems in the prior art that when using a pneumatic clamping device to clamp the outer circle of the pulley for torque detection operation, the outer circle of the pulley is often damaged, and the efficiency is low and the labor intensity is high.
[0030] See Figure 1 , Figure 1 Provide a generator torque detection auxiliary tool, as Figure 1As shown, in one embodiment, the generator torque detection auxiliary tool includes a base 1 and a plurality of positioning blocks 3. A bearing positioning seat 2 is provided at the center of the top surface of the base 1, and a plurality of positioning holes 11 for fixing the base 1 are evenly provided around the bearing positioning seat 2. A plurality of positioning blocks 3 are fixed on the peripheral side of the bearing positioning seat 2, located at the edge of the base 1, and at least one stopper 4 for blocking the rotation of the engine body is installed on the plurality of positioning blocks 3.
[0031] In this embodiment, the engine torque detection auxiliary tool includes a base 1 and a plurality of positioning blocks 3. By providing a bearing positioning seat 2 at the center of the top surface of the base 1 to support the engine bearing, the damage of the engine bearing can be avoided.
[0032] In addition, by evenly providing a plurality of positioning holes 11 for fixing the base 1 around the bearing positioning seat 2, a positioning member (such as a positioning pin or a positioning nail) is used to pass through the positioning holes 11 on the base 1, and then the engine torque detection auxiliary tool is placed on the equipment workbench. The plurality of positioning holes 11 are evenly arranged around the bearing positioning seat 2, which is beneficial to keeping the force balance of the engine torque detection auxiliary tool on the workbench and avoiding the tilting and overturning of the engine torque detection auxiliary tool during use.
[0033] By fixing a plurality of positioning blocks 3 on the peripheral side of the bearing positioning seat 2, located at the edge of the base 1, and at least one stopper 4 for blocking the rotation of the engine body is installed on the plurality of positioning blocks 3, a space for accommodating the engine can be formed, and the positioning blocks 3 can also support the engine. When the staff detects the engine torque, a torque wrench is usually used to tighten the nut on the top of the engine pulley. At this time, the engine body will rotate in the tightening direction of the torque wrench, resulting in the torque wrench being unable to tighten the nut. Therefore, at least one stopper 4 can be installed on the plurality of positioning blocks 3, which can be abutted against the magnetic pole gap of the engine rotor to prevent the engine body from rotating and ensure that the torque wrench successfully detects the torque of the nut.
[0034] As Figure 1 As shown, in some embodiments, a first through hole 12 is provided at the center of the top surface of the base 1, and a bearing positioning seat 2 is detachably installed in the first through hole 12. In this embodiment, the bearing positioning seat 2 can prevent the position deviation of the engine bearing and improve the overall stability. By providing a first through hole 12 at the center of the top surface of the base 1 and detachably installing a bearing positioning seat 2 in the first through hole 12, the installation and disassembly of the bearing base 1 become simple and fast, improving the convenience and efficiency of maintenance.
[0035] In addition, different types of bearing positioning seats 2 can also be replaced according to actual needs to adapt to different specifications and types of bearings, enhancing the versatility and flexibility of the equipment.
[0036] See Figure 2 , Figure 2 which is Figure 1 a sectional view of the bearing positioning seat in the present application. As Figure 2 shown, in some embodiments, the bearing positioning seat 2 includes an upper cylinder 21 for supporting the engine bearing and a lower cylinder 22 for connecting to the base 1. A second through hole 213 for receiving the guide rod of the engine commutator is provided at the center of the top surface of the upper cylinder 21, and the second through hole 213 penetrates through the upper cylinder 21 and the lower cylinder 22. The lower cylinder 22 is disposed within the first through hole 12. In this embodiment, the bearing positioning seat 2 includes two parts. One part is the upper cylinder 21 for supporting the engine bearing, and the other part is the lower cylinder 22 for connecting to the base 1. By providing the second through hole 213 for receiving the guide rod of the engine commutator at the center of the top surface of the upper cylinder 21, and the second through hole 213 penetrates through the upper cylinder 21 and the lower cylinder 22, and the lower cylinder 22 is disposed within the first through hole 12, in this way, the bearing positioning seat 2 can not only effectively support the bearing, but also directly connect to the base 1, making the structure more compact and strengthening the stability of the overall structure. In addition, it is beneficial to the precise positioning of the engine commutator.
[0037] As Figure 2 shown, in some embodiments, a circular groove 211 is formed by inward depression of the top surface of the upper cylinder 21, and an annular groove 212 is provided on the inner bottom surface of the circular groove 211 around the second through hole 213. In this embodiment, by forming the circular groove 211 by inward depression of the top surface of the upper cylinder 21, and providing the annular groove 212 on the inner bottom surface of the circular groove 211 around the second through hole 213, this can ensure that the engine bearing is better fixed by the bearing positioning seat 2 and is difficult to shift in position.
[0038] See Figure 3 , Figure 3 which is Figure 1 a top view of the base in the present application. As Figure 3 shown, in some embodiments, a plurality of third through holes 13 are provided around the first through hole 12, and the positioning block 3 is vertically mounted on the base 1 through the third through holes 13. In this embodiment, by providing a plurality of third through holes 13 around the first through hole 12 and vertically mounting the positioning block 3 on the base 1 through the third through holes 13, this can make the positioning block 3 more firmly mounted on the base 1. The installation method is as follows: 1. The bottom of the positioning block 3 has a plug-in member, and the positioning block 3 can be directly inserted into the base 1 through the plug-in member for vertical installation; 2. An installation hole is provided at the bottom end of the positioning block 3, and fixing members such as screws and bolts pass through the third through holes 13 on the base 1 and the installation hole at the bottom end of the positioning block 3, and then the positioning block 3 is vertically mounted on the base 1. No matter which of the above installation methods is selected, the positioning block 3 can be stably mounted on the base 1 without shaking.
[0039] As shown Figure 1 In some embodiments, the positioning block 3 includes a supporting portion 31 for supporting the rear end cover of the engine and a connecting portion 32 for connecting to the base 1. The cross-sectional thickness of the supporting portion 31 is smaller than that of the connecting portion 32, and a mounting hole is provided at the bottom end of the connecting portion 32. In this embodiment, the positioning block 3 includes two parts, namely the supporting portion 31 and the connecting portion 32. The supporting portion 31 of the positioning block 3 is used to support the rear end cover of the engine, and the connecting portion 32 of the positioning block 3 is used to connect to the base 1 of the positioning block 3, that is: the positioning block 3 is mounted on the base 1 through the connecting portion 32. Further, the cross-sectional thickness of the supporting portion 31 is smaller than that of the connecting portion 32. As the connection point between the supporting portion 31 and the base 1, the cross-sectional thickness of the connecting portion 32 is increased, so that the connecting portion 32 can withstand greater external forces, reducing the risk of damage caused by stress concentration, thereby enhancing the strength and stability of the entire structure. And a mounting hole is provided at the bottom end of the connecting portion 32, which can accurately align and fix other components, ensuring the accuracy and stability of the installation.
[0040] As shown Figure 1 In some embodiments, the inner side surface of the positioning block 3 has a certain curvature. In this embodiment, since the engine is generally cylindrical, when using this auxiliary tool for engine torque detection, the positioning block 3 is needed to fix it. The inner side surface of the positioning block 3 has a certain curvature, which can better fit the engine, so that there will not be too much gap between the two, and at the same time, it also saves casting materials.
[0041] As shown Figure 3 In some examples, the positioning hole 11 is located between the side walls of two adjacent positioning blocks 3. In this embodiment, the positioning hole 11 is used to fixedly mount the base 1 (engine torque detection auxiliary tool) on the workbench. The installation method is as follows: there are positioning pins or positioning nails on the workbench, and by passing the positioning pins or positioning nails through the positioning hole 11, the fixed installation of the base 1 (engine torque detection auxiliary tool) is achieved. And, the positioning pins or positioning nails need to completely pass through the positioning hole 11 to ensure that the base 1 (engine torque detection auxiliary tool) will not easily tilt or overturn when the staff is performing torque detection. By setting the positioning hole 11 between the side walls of two adjacent positioning blocks 3, this can avoid interference between the positioning pins or positioning nails on the workbench and the positioning block 3, or when placing the engine, the positioning pins or positioning nails will hinder the placement of the engine on the positioning block 3.
[0042] As shown Figure 1As shown, in some embodiments, the stop block 4 is in an inverted "L" shape. Its horizontal block 41 is disposed on the side wall of the positioning block 3 facing the rotation direction of the engine body, and the vertical block 42 is fixedly installed on this side wall. In this embodiment, the stop block 4 is set in an inverted "L" shape, so that the stop block 4 is supported in both the horizontal and vertical directions, thereby enhancing the stability of the entire structure. The rotation direction of the engine body means that when performing the engine torque detection, the torque wrench may drive the engine body to rotate synchronously, resulting in the inability to smoothly perform the torque detection. Therefore, a stop block 4 can be provided to prevent the engine body from rotating. By setting the horizontal block 41 of the stop block 4 on the side wall of the positioning block 3 facing the rotation direction of the engine body and fixedly installing the vertical block 42 on this side wall, a reaction force can be formed by the horizontal block 41 against the engine body to prevent the engine body from rotating. And the vertical block 42 and the horizontal block 41 are of an integral structure and are different parts of the stop block 4. The vertical block 42 is fixedly installed on this side wall, enhancing the stability of the horizontal block 41.
[0043] In some embodiments, the outer surface of the generator torque detection auxiliary tool is covered with a protective coating. In this embodiment, by covering the outer surface of the engine torque detection auxiliary tool with a protective coating, the direct contact between the outer surface of the auxiliary tool and corrosive substances (such as moisture, oxygen, acids and alkalis, etc.) in the external environment can be isolated, thereby slowing down or preventing the oxidation and corrosion process on the surface of the auxiliary tool. This helps to extend the service life of the auxiliary tool and reduce the performance degradation or damage caused by corrosion. And during the use process, the generator torque detection auxiliary tool may rub against various materials or surfaces. The protective coating can increase the hardness and wear resistance of the surface of the auxiliary tool, reduce the wear caused by friction, and maintain the accuracy and performance of the auxiliary tool.
