Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a grinding equipment for the surface of automobile flywheels. Background Technology

[0002] The grinding equipment is used to grind the surface of car flywheels. The equipment consists of a worktable, a slide, a motor assembly, a lead screw assembly, a moving table, a mounting table, a drive shaft, a grinding wheel, a three-jaw chuck, and a slide rail. When using the equipment, the car flywheel is fixed in place by the three-jaw chuck. Then, the first motor is started, causing the first lead screw to rotate, which in turn moves the moving table within the slide. Simultaneously, the second motor is started, causing the second lead screw to rotate, which in turn moves the mounting table within the slide rail. The third motor is started, causing the drive shaft to rotate, which in turn rotates the grinding wheel. Finally, the fourth motor is started, causing the three-jaw chuck to rotate, which in turn rotates the car flywheel. This causes the grinding wheel to rotate and approach the car flywheel for grinding, thus polishing the flywheel.

[0003] The inventors discovered in their daily work that when using grinding equipment, the grinding wheels are easily worn out, requiring replacement. The grinding wheels are fixed to the drive shaft using multiple sets of screws, which makes replacement inconvenient. This involves removing multiple sets of screws, replacing the new grinding wheel with the drive shaft, and then fixing it with screws again. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in actual use, the grinding wheel is easily worn out, so the grinding wheel needs to be replaced. The grinding wheel is fixed to the drive shaft with multiple sets of screws, which makes the replacement process very inconvenient. Therefore, this utility model proposes a surface grinding device for automotive flywheel processing.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a surface grinding device for automotive flywheel processing, comprising a worktable, with sliding grooves on both sides of the upper end of the worktable, a first lead screw provided on the inner wall of the sliding groove, a movable stage slidably connected to the inner wall of the sliding groove, the movable stage and the first lead screw being threadedly connected, a first motor installed at the left end of the worktable, the output end of the first motor being fixed to the first lead screw, a slide rail provided at the upper end of the movable stage, a second lead screw provided on the inner wall of the slide rail, a mounting platform slidably connected to the inner wall of the slide rail, the mounting platform and the second lead screw being threadedly connected, a second motor installed at one end of the movable stage, the output end of the second motor being fixed to the second lead screw, a third motor installed on the front of the mounting platform, the third... The output ends of the three motors are fixedly connected to a drive shaft. A grinding wheel is provided on the arc surface of the drive shaft. A replacement assembly is provided between the grinding wheel and the drive shaft. A fourth motor is installed at the right end of the worktable. An anti-splash assembly is provided at the upper end of the worktable. A three-jaw chuck is installed at the output end of the fourth motor. The replacement assembly includes multiple evenly distributed positioning blocks that are slidably inserted into the arc surface of the drive shaft. The positioning blocks are inserted into the grinding wheel. A push rod is fixedly connected to one end of the positioning block. The push rod passes through the drive shaft. An operating cavity is opened inside the drive shaft. A pusher is slidably connected to the inner wall of the operating cavity. A pressing rod is slidably inserted into the bottom of the inner wall of the operating cavity. An adjusting screw is rotatably connected to the upper end of the pressing rod. The adjusting screw is threadedly connected to the drive shaft.

[0006] The effect achieved by the above components is as follows: by setting the replacement component, when the grinding wheel needs to be replaced, the adjusting screw is turned so that the lower pressure rod moves upward. Under the action of the reset mechanism, the pusher in the operating cavity moves to the right, so that multiple positioning blocks are completely retracted into the drive shaft. Then, the grinding wheel is dragged to remove it. Immediately afterwards, the new grinding wheel is installed on the drive shaft. The adjusting screw is turned again so that the downward pressing pusher pushes the push rod, thereby locking the positioning block into the grinding wheel, thus making the replacement of the grinding wheel as convenient as possible.

[0007] Preferably, a first spring is fixedly connected to the upper end of the positioning block, and the other end of the first spring is fixed to the drive shaft.

[0008] The effect achieved by the above components is to reset the positioning block by setting the first spring.

[0009] Preferably, a second spring is fixedly connected to the left end of the pusher, and the other end of the second spring is fixed to the drive shaft.

[0010] The effect achieved by the above components is to reset the pushing component by setting a second spring.

[0011] Preferably, a limiting block is fixedly connected to the arc surface of the drive shaft, the drive shaft is inserted into the grinding wheel, and a limiting groove is formed on the inner wall of the grinding wheel.

[0012] The effect achieved by the above components is to assist the grinding wheel in being engaged with the drive shaft by setting limit blocks and limit grooves.

[0013] Preferably, the limiting groove is adapted to the limiting block, and the limiting block slides within the limiting groove.

[0014] The effect achieved by the above components is that, by setting limit blocks and limit grooves, the auxiliary positioning block is engaged into the grinding wheel groove.

[0015] Preferably, the anti-splash assembly includes an anti-splash ring rotatably connected to the upper end of the workbench, a circular rod fixedly connected to the upper end of the workbench, and a rotating plate rotatably connected to the arc surface of the circular rod.

[0016] The effect achieved by the above components is as follows: when it is necessary to prevent the sparks generated by the grinding wheel grinding the car flywheel, the anti-splash ring is rotated, and then the rotating plate on the circular rod is rotated. The rotating plate is squeezed to the other end of the anti-splash ring to limit it, so that the sparks generated by grinding are blocked by the anti-splash ring, thereby preventing splashing.

[0017] Preferably, a positioning pin is slidably inserted into the upper end of the rotating plate, and the positioning pin is inserted into the worktable.

[0018] The effect achieved by the above components is to secure the anti-splash ring by inserting it into the worktable through the positioning pin.

[0019] Preferably, the arc surface of the positioning pin is provided with a protrusion, and the lower end of the rotating plate is fixedly connected with a rubber pad.

[0020] The effect achieved by the above components is to assist the rotating plate in limiting the anti-splash ring by setting rubber pads.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting a replacement component, when the grinding wheel needs to be replaced, the adjusting screw is turned, causing the lower pressure rod to move upward. Under the action of the reset mechanism, the pushing component in the operating cavity moves to the right, causing multiple positioning blocks to fully retract into the drive shaft. Then, the grinding wheel is dragged to disassemble. Next, a new grinding wheel is installed onto the drive shaft. The adjusting screw is turned again, causing the downward pressing pushing component to push the push rod, thereby locking the positioning blocks into the grinding wheel. This makes it as convenient as possible to replace the grinding wheel. This solves the problem that grinding wheels are easily worn out during grinding, requiring replacement. The grinding wheel is fixed to the drive shaft using multiple sets of screws, which means that replacement requires removing multiple sets of screws, replacing the new grinding wheel onto the drive shaft, and then fixing it with screws, making the entire replacement process very inconvenient.

[0029] The following section will explain the specific settings and functions of replacing component 2 and anti-splash component 3.

[0030] Reference Figure 3 and Figure 4As shown, in this embodiment: the replacement component 2 includes multiple evenly distributed positioning blocks 21 slidably inserted into the arc surface of the drive shaft 13. The positioning blocks 21 are inserted into the grinding wheel 14. One end of the positioning block 21 is fixedly connected to a push rod 22, which passes through the drive shaft 13. An operating cavity 23 is opened inside the drive shaft 13. A pusher 24 is slidably connected to the inner wall of the operating cavity 23. A pressing rod 25 is slidably inserted into the bottom of the inner wall of the operating cavity 23. An adjusting screw is rotatably connected to the upper end of the pressing rod 25. 26. The adjusting screw 26 is threadedly connected to the drive shaft 13. By setting the replacement component 2, when the grinding wheel 14 needs to be replaced, the adjusting screw 26 is turned, causing the lower pressure rod 25 to move upward. Under the action of the reset mechanism, the pusher 24 in the operating cavity 23 moves to the right, causing multiple positioning blocks 21 to be completely retracted into the drive shaft 13. Then, the grinding wheel 14 is dragged to disassemble. Immediately afterwards, a new grinding wheel 14 is installed onto the drive shaft 13. The adjusting screw 26 is turned again, causing the downward pressing pusher 24 to push the push rod 22, thereby locking the positioning block 21 into the grinding wheel 14, thus facilitating the replacement of the grinding wheel 14 as much as possible. The upper end of the positioning block 21 is fixedly connected to a first spring 28, and the other end of the first spring 28 is fixed to the drive shaft 13. By setting the first spring 28, the positioning block 21 is reset.

By setting the second spring 27, the positioning block 21 is reset. The pusher 24 is reset, and the arc surface of the drive shaft 13 is fixedly connected to the limiting block 29. The drive shaft 13 is inserted into the grinding wheel 14. The inner wall of the grinding wheel 14 is provided with a limiting groove 210. By setting the limiting block 29 and the limiting groove 210, the grinding wheel 14 is assisted to be inserted into the drive shaft 13. The limiting groove 210 is adapted to the limiting block 29, and the limiting block 29 slides in the limiting groove 210. By setting the limiting block 29 and the limiting groove 210, the auxiliary positioning block 21 is inserted into the groove of the grinding wheel 14.

[0031] Reference Figure 2 As shown in this embodiment: the anti-splash assembly 3 includes an anti-splash ring 31 rotatably connected to the upper end of the workbench 1. A circular rod 32 is fixedly connected to the upper end of the workbench 1. A rotating plate 33 is rotatably connected to the arc surface of the circular rod 32. When it is necessary to prevent the grinding wheel 14 from grinding the sparks generated by the car flywheel, the anti-splash ring 31 is rotated, and then the rotating plate 33 on the circular rod 32 is rotated. The rotating plate 33 is squeezed to the other end of the anti-splash ring 31 to limit it, so that the sparks generated by grinding are blocked by the anti-splash ring 31, thereby preventing splashing. A positioning pin 34 is slidably inserted into the upper end of the rotating plate 33. The positioning pin 34 is inserted into the workbench 1 and is locked into the workbench 1 to further fix the anti-splash ring 31. The arc surface of the positioning pin 34 is provided with a protrusion. A rubber pad is fixedly connected to the lower end of the rotating plate 33. By setting the rubber pad, the rotating plate 33 is assisted in limiting the anti-splash ring 31.

[0032] Working principle:

[0033] When using the grinding equipment, the car flywheel is fixed by a three-jaw chuck 15 (the three-jaw chuck 15 is a commercially available product; how to fix the flywheel is existing technology and will not be elaborated here). Then, the first motor 7 is started, causing the first lead screw 5 to rotate, which makes the moving table 6 slide in the slide groove 4. At the same time, the second motor 10 is started, causing the second lead screw 9 to rotate, which makes the mounting table 11 move in the slide rail 8. The third motor 12 is started, causing the drive shaft 13 to rotate, which makes the grinding wheel 14 rotate. The fourth motor 16 is started, causing the three-jaw chuck 15 to rotate, which makes the car flywheel rotate. Thus, the grinding wheel 14 rotates and approaches the car flywheel for grinding. When the grinding wheel 14 needs to be replaced, the adjusting lead screw 26 is turned, which moves the lower pressure rod 25 upward. The first spring 28 is used to reset the positioning block 21, and the second spring 27 is used to reset the pushing member 24, which moves the pushing member 24 in the operating cavity 23 to the right, causing multiple positioning blocks to move to the right. Positioning block 21 is fully retracted into drive shaft 13. Then, the grinding wheel 14 is removed. Next, a new grinding wheel 14 is installed onto drive shaft 13. The adjusting screw 26 is turned again, causing the downward pressing pusher 24 to push push rod 22, thereby engaging positioning block 21 into grinding wheel 14. This facilitates the replacement of grinding wheel 14 as conveniently as possible. Limiting blocks 29 and limiting grooves 210 are used to assist in engaging grinding wheel 14 into drive shaft 13. The positioning block 21 is inserted into the groove of the grinding wheel 14. When it is necessary to prevent the grinding wheel 14 from grinding the sparks generated by the car flywheel, the anti-splash ring 31 is rotated, and then the rotating plate 33 on the circular rod 32 is rotated. The rotating plate 33 is squeezed to the other end of the anti-splash ring 31 to limit it, so that the sparks generated by grinding are blocked by the anti-splash ring 31, thus preventing splashing. The positioning pin 34 is inserted into the worktable 1 to further fix the anti-splash ring 31. By setting the rubber pad, the rotating plate 33 is assisted in limiting the anti-splash ring 31.
