Description
Technical Field
[0001] This utility model relates to the field of drill bushing processing technology, and in particular to an automatic drill bushing grinding device. Background Technology
[0002] The primary function of drill bushings is to determine the axial position of fixed-size cutting tools such as drills, reamers, and boring bars. The structure and dimensions of drill bushings are standardized. Based on usage characteristics, drill bushings come in four types: fixed drill bushings, replaceable drill bushings, quick-change drill bushings, and special-purpose drill bushings. The significance of drill bushings lies in their ability to position and guide cutting tools during machining, thereby improving machining accuracy.
[0003] Currently, when grinding drill bushings, most of the time workers hold the grinding equipment and manually grind the drill bushing after it is clamped and fixed. This is not only laborious, but also prone to causing some areas of the drill bushing to not be fully ground during the manual grinding process, thus affecting the overall quality of the drill bushing after grinding.
[0004] Therefore, it is necessary to provide an automatic drill bushing grinding device to solve the above-mentioned technical problems. Utility Model Content

[0029] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0030] According to one embodiment of the present invention, in conjunction with Figure 1-4As shown. An automatic grinding device for drill bushings includes: a processing table 1, a control panel 11 on the top of the processing table 1, a threaded rod 2 and a rotating shaft 3 rotatably connected to the top of the processing table 1, a movable block 4 threadedly connected to the outer surface of the threaded rod 2, a support plate 5 fixedly connected to one side of the movable block 4, a grinding assembly mounted on the support plate 5, a placement plate 6 fixedly connected to the top of the rotating shaft 3, two moving grooves 7 extending through the placement plate 6, a push plate 8 slidably connected inside the moving grooves 7, a positioning block 9 rotatably connected to the top of the push plate 8, a mounting frame 12 and an electro-hydraulic rod 10 fixedly connected to the top of the processing table 1, the bottom of the mounting frame 12 rotatably connected to the top of the threaded rod 2, and a grinding assembly mounted on the top of the rotating shaft 3. The workbench 1 is equipped with a rotating component and a positioning component. Through the arrangement of the workbench 1, threaded rod 2, rotating shaft 3, placement plate 6, positioning block 1 9, guide groove 13, diamond grinding wheel 22 and limit block 25, the drill bushing can be rotated to the position below positioning block 2 17 for clamping. This prevents the positioning block 2 17 and other structures from obstructing the loading and unloading of the drill bushing, thus improving the loading and unloading efficiency. At the same time, when the drill bushing is being ground, the diamond grinding wheel 22 is fully in contact with the outer surface of the drill bushing, and while it is rotating, it performs up and down grinding work, so that the outer surface of the drill bushing is fully ground. This avoids the inconvenience caused by manual grinding by workers and improves the overall quality of the drill bushing after grinding.
[0031] In this embodiment, a guide groove 13 is provided on one side of the mounting bracket 12, and a guide block 14 is slidably connected inside the guide groove 13. The guide block 14 is fixedly connected to the moving block 4. By setting the guide groove 13 and the guide block 14, the moving block 4 can be guided and limited, so that the moving block 4 can move up and down.
[0032] In this embodiment, the rotating assembly includes a stepper motor 15 fixedly installed at the bottom of the mounting bracket 12. The output end of the stepper motor 15 is fixedly connected to a connecting rod 16. A transmission mechanism 18 is connected between the outer surface of the connecting rod 16 and the outer surface of the threaded rod 2. A positioning block 2 17 is fixedly connected to the bottom of the connecting rod 16. By setting the rotating assembly, the positioning block 2 17 can be driven to rotate, and with the cooperation of the electric hydraulic rod 10 and the positioning block 1 9, the drill sleeve is clamped and driven to rotate.
[0033] In this embodiment, the grinding assembly includes a connecting plate 19 slidably connected to the top of the support plate 5. Two springs 20 are fixedly connected to one side of the connecting plate 19, and a drive motor 21 is fixedly installed on the other side of the connecting plate 19. A diamond grinding wheel 22 is fixedly connected to the output end of the drive motor 21. By setting the grinding assembly, the diamond grinding wheel 22 can be made to abut against the outer surface of the drill bushing under the elastic force of the spring, so that the outer surface of the drill bushing can be fully ground.
[0034] In this embodiment, the positioning component includes a second spring 23 and two limiting grooves 24. The second spring 23 is fixedly connected to the top of the processing table 1, and the other end of the second spring 23 is fixedly connected to a limiting block 25. Both limiting grooves 24 are opened on the outer surface of the rotating shaft 3, and the limiting block 25 is movably inserted into one of the limiting grooves 24. By setting the positioning component, the rotating shaft 3 can be limited and fixed to prevent it from rotating during use and affecting the grinding work of the drill sleeve.
[0035] Working principle: In use, the drill bushing to be ground is placed on top of one of the positioning blocks 19, and the limiting block 25 is moved to remove it from the corresponding limiting groove 24. Then, the placement plate 6 is rotated. With the cooperation of the rotating shaft 3, the placement plate 6 drives the placed drill bushing to rotate until the limiting block 25, with the cooperation of the second spring 23, is inserted into the other limiting groove 24, limiting and fixing the rotating shaft 3 and the placement plate 6. At the same time, the drill bushing rotated to the position below the second positioning block 17 presses against the diamond wheel 22, causing it to drive the drive motor 21 and the connecting plate 19 to slide on the support plate 5, and press against the corresponding spring 20, so that the diamond wheel 22 can fully abut against the drill bushing. Then, the grinding process begins. The electric hydraulic rod 10 is activated, extending its telescopic end to push the corresponding push plate 8 upward, which in turn moves the corresponding positioning block 9 and the drill bushing to be ground upward. With the cooperation of the positioning block 17, the drill bushing is clamped and fixed. Then, the drive motor 21 and the stepper motor 15 can be started. After the drive motor 21 starts, it drives the diamond wheel 22 to rotate, performing the grinding work on the drill bushing. After the stepper motor 15 starts, it drives the drill bushing to rotate, and under the transmission mechanism 18, it causes the threaded rod 2 to rotate. Under the guidance and limitation of the guide groove 13 and the guide block 14, the support plate 5 drives the drive motor 21 and the diamond wheel 22 to move up and down, so that the outer surface of the drill bushing can be fully ground.
[0036] Working principle: In use, the drill bushing to be ground is placed on top of one of the positioning blocks 19, and the limiting block 25 is moved to remove it from the corresponding limiting groove 24. Then, the placement plate 6 is rotated. With the cooperation of the rotating shaft 3, the placement plate 6 drives the placed drill bushing to rotate until the limiting block 25, with the cooperation of the second spring 23, is inserted into the other limiting groove 24, limiting and fixing the rotating shaft 3 and the placement plate 6. At the same time, the drill bushing rotated to the position below the second positioning block 17 presses against the diamond wheel 22, causing it to drive the drive motor 21 and the connecting plate 19 to slide on the support plate 5, and press against the corresponding spring 20, so that the diamond wheel 22 can fully abut against the drill bushing. Then, the grinding process begins. The electric hydraulic rod 10 is activated, extending its telescopic end to push the corresponding push plate 8 upward, which in turn moves the corresponding positioning block 9 and the drill bushing to be ground upward. With the cooperation of the positioning block 17, the drill bushing is clamped and fixed. Then, the drive motor 21 and the stepper motor 15 can be started. After the drive motor 21 starts, it drives the diamond wheel 22 to rotate, performing the grinding work on the drill bushing. After the stepper motor 15 starts, it drives the drill bushing to rotate, and under the transmission mechanism 18, it causes the threaded rod 2 to rotate. Under the guidance and limitation of the guide groove 13 and the guide block 14, the support plate 5 drives the drive motor 21 and the diamond wheel 22 to move up and down, so that the outer surface of the drill bushing can be fully ground.
