Description

Technical Field

[0001] This application relates to the field of gear machining, and in particular to an online measuring mechanism for a quick-assembly gear grinding machine. Background Technology

[0002] Gear grinding machines are key equipment used in high-precision gear machining, achieving precision grinding of complex tooth profiles through CNC technology. Their core functions include grinding cylindrical spur gears, involute helical gears, and splines. They can meet machining needs for different modules and diameter ranges, supporting the machining of spur, helical, bevel, and spiral gears. The maximum machining module reaches 6mm, with a precision grade of 3. Employing high-precision continuous generating grinding technology, they are widely used in the automotive, construction machinery, and other fields.

[0003] Currently, when processing gears on a gear grinding machine, it is necessary to use gears that are compatible with the processing to ensure that the involute is properly matched. However, the measuring mechanism currently in use is inconvenient to adjust its position, making the measurement process inconvenient and hindering the improvement of overall processing efficiency. Utility Model Content

[0004] To address the problem that current measuring mechanisms are inconvenient to adjust during use, making measurement difficult and hindering overall processing efficiency, this application provides a quick-assembly online measuring mechanism for gear grinding machines.

[0005] The quick-assembly online measurement mechanism for gear grinding machines provided in this application adopts the following technical solution:

[0006] The device includes a base and a lifting platform. A guide rail is installed on the lifting platform, and a first slider and a second slider are slidably mounted on the guide rail. A movable plate is installed on the first slider, and a column is installed on the movable plate. A measuring gear is installed on the column. A fixed plate is installed on the second slider, and a measuring gauge is installed on the fixed plate. An extension is installed in the middle of one side of the movable plate, and the measuring head of the measuring gauge abuts against the extension.

[0007] By adopting the above technical solution, the first slider at the bottom of the moving plate moves along the guide rail to ensure the smoothness of the moving plate. When the moving plate moves, it drives the measuring gear to gradually approach the gear to be tested. At the same time, the pointer of the measuring instrument changes. The accuracy of the gear is determined based on the pointer change.

[0008] Preferably, a limiting component is installed on the lifting platform, and a rotating rod is rotatably mounted on the limiting component, and the rotating rod is threaded.

[0009] By adopting the above technical solution, the rotating rod can be rotated, and the rotating rod can drive the moving plate to move horizontally through the thread.

[0010] Preferably, the rotating rod extends through the lower part of the extension and is connected to the extension by a thread.

[0011] By adopting the above technical solution, when the moving plate moves, it drives the measuring gear to gradually approach the gear to be tested, and at the same time the pointer of the measuring instrument changes, which facilitates measurement.

[0012] Preferably, fastening bolts are installed at both ends of the fixing plate, the lower part of the fastening bolts passes through the second slider, and the lower end of the fastening bolts abuts against the guide rail.

[0013] By adopting the above technical solution, the lower part of the fastening bolt is separated from the guide rail by rotating the fastening bolt. At this time, the fixing plate and the second slider can be pushed to move the measuring instrument.

[0014] Preferably, a fixing block is installed on the base, a first shear bar is movably installed on the fixing block, and a second shear bar is movably installed on the side of the lifting platform.

[0015] By adopting the above technical solution, the connecting rod can push the lower part of the second shear bar to move. At this time, the second shear bar moves around the central axis, and the upper end will gradually lift the lifting platform. The lifting platform drives the upper part of the first shear bar to move inside it, and the lifting platform moves upward.

[0016] Preferably, the first shear bar and the second shear bar are arranged in a cross configuration, and the intersection is movably connected by a central shaft. The upper end of the first shear bar is movably connected to the inner side of the lifting platform and can move within the lifting platform.

[0017] By adopting the above technical solution, the second shear bar moves around the central axis, and its upper end gradually lifts the lifting platform. The lifting platform then drives the upper part of the first shear bar to move inside it.

[0018] Preferably, a connecting rod is installed at the lower end of the second shear bar, and a screw is installed on the base, with the screw and the connecting rod being threaded together at the middle.

[0019] By adopting the above technical solution, rotating the screw drives the connecting rod to move, and the connecting rod can push the lower part of the second shear bar to move.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application uses a threaded drive to move the moving plate horizontally. At this time, the first slider at the bottom of the moving plate moves along the guide rail to ensure the smooth movement of the moving plate. When the moving plate moves, it drives the measuring gear to gradually approach the gear to be tested. At the same time, the pointer of the measuring instrument changes. Based on the pointer change, the accuracy of the gear is determined, which facilitates the movement of the measuring gear.

[0022] 2. In this application, the connecting rod is driven by a screw to move. The connecting rod can push the lower part of the second shear rod to move. At this time, the second shear rod moves around the central axis, and the upper end will gradually lift the lifting platform. The lifting platform drives the upper part of the first shear rod to move inside it. At this time, the lifting platform moves up, and the lifting platform drives the measuring gear to move up, so as to adjust the height of the measuring gear so that it is the same as the height of the gear to be measured.

The first slider 4 and the second slider 5 can move along the guide rail 3. A movable plate 6 is mounted on the first slider 4, and a column 7 is mounted on the movable plate 6. A measuring gear 8 is mounted on the column 7. A fixed plate 9 is mounted on the second slider 5, and a measuring gauge 10 is mounted on the fixed plate 9. An extension 14 is mounted on the middle of one side of the movable plate 6. The measuring head of the measuring instrument 10 abuts against the extension 14. A limiting component 11 is installed on the lifting platform 2. A rotating rod 12 is rotatably installed on the limiting component 11. The rotating rod 12 has a thread 13. The moving plate 6 is driven to move horizontally through the thread 13. At this time, the first slider 4 at the bottom of the moving plate 6 moves along the guide rail 3 to ensure the smooth movement of the moving plate 6. When the moving plate 6 moves, it drives the measuring gear 8 to gradually approach the gear to be tested. At the same time, the pointer of the measuring instrument 10 changes. The accuracy of the gear is determined according to the pointer change.

[0030] Please refer to Figure 3 and Figure 4 The rotating rod 12 passes through the lower part of the extension 14 and is connected to the extension 14 by the thread 13. Fastening bolts 15 are installed at both ends of the fixing plate 9. The lower part of the fastening bolt 15 passes through the second slider 5 and the lower end of the fastening bolt 15 abuts against the guide rail 3. By rotating the fastening bolt 15, the lower part of the fastening bolt 15 is separated from the guide rail 3. At this time, the fixing plate 9 and the second slider 5 can be pushed to move the measuring instrument 10 to adjust the position of the measuring instrument 10.

[0031] Please refer to Figure 1 and Figure 2 A fixing block 16 is installed on the base 1, and a first shear rod 17 is movably installed on the fixing block 16. A second shear rod 18 is movably installed on the side of the lifting platform 2. The first shear rod 17 and the second shear rod 18 are arranged in a cross configuration, and the intersection is movably connected by a central shaft 19. The upper end of the first shear rod 17 is movably connected to the inner side of the lifting platform 2 and can move within the lifting platform 2. A connecting rod 20 is installed at the lower end of the second shear rod 18. A screw 21 is installed on the base 1, and the middle of the screw 21 and the connecting rod 20 are threaded together. When the screw 21 is rotated, the screw 21 drives the connecting rod 20 to move. The connecting rod 20 can push the lower part of the second shear rod 18 to move. At this time, the second shear rod 18 moves around the central shaft 19, and the upper end will gradually lift the lifting platform 2. The lifting platform 2 drives the upper part of the first shear rod 17 to move within it. At this time, the lifting platform 2 moves upward, and the lifting platform 2 drives the measuring gear 8 to move upward, so as to adjust the height of the measuring gear 8.

[0032] The implementation principle of the online measuring mechanism of the quick-assembly gear grinding machine in this application embodiment is as follows: When it is necessary to measure the gear, first rotate the screw 21. The screw 21 drives the connecting rod 20 to move. The connecting rod 20 can push the lower part of the second shear rod 18 to move. At this time, the second shear rod 18 moves around the central axis 19, and the upper end will gradually lift the lifting platform 2. The lifting platform 2 drives the upper part of the first shear rod 17 to move inside it. At this time, the lifting platform 2 moves upward, and the lifting platform 2 drives the measuring gear 8 to move upward, so as to adjust the height of the measuring gear 8 to be the same as the height of the gear to be measured; at this time, rotate the screw 21 to move the connecting rod 20 to move the connecting rod 20 to move the connecting rod 20 to move the connecting rod 20 to move the connecting rod 18 ... When the moving rod 12 rotates, it can drive the moving plate 6 to move horizontally through the thread 13. At this time, the first slider 4 at the bottom of the moving plate 6 moves along the guide rail 3 to ensure the smooth movement of the moving plate 6. When the moving plate 6 moves, it drives the measuring gear 8 to gradually approach the gear to be tested. At the same time, the pointer of the measuring instrument 10 changes. The accuracy of the gear is determined according to the pointer change. By rotating the fastening bolt 15, the lower part of the fastening bolt 15 is separated from the guide rail 3. At this time, the fixed plate 9 and the second slider 5 can be pushed to drive the measuring instrument 10 to move, so as to adjust the position of the measuring instrument 10.
