Description

Technical Field

[0001] This utility model belongs to the field of workpiece grinding technology, and in particular relates to a rotating device for grinding a semi-circular front cover. Background Technology

[0002] In the production and processing of equipment workpieces, grinding is required. This grinding process uses a grinding device to remove burrs from the workpiece surface and ensure its smoothness. However, in actual grinding processes, we have found that manually controlling the workpiece during grinding presents some problems. For example, when the workpiece contacts the grinding wheel, the grinding angle and position are manually controlled. During this process, the hand lacks a stable support point and is easily injured by touching the grinding wheel. Moreover, it is difficult to precisely control the force and angle during grinding. Often, after grinding a small portion, the workpiece is retracted to adjust its position and angle before re-engaging with the grinding wheel. This requires the worker to concentrate on observing the grinding process, which is time-consuming, labor-intensive, and inefficient. A moment of carelessness can easily turn the workpiece into a scrap. Utility Model Content

[0023] Example 1:

[0024] A rotating device for polishing a semi-circular front cover includes a worktable 1: a guide rail 2 is provided through the bottom of the worktable 1, and a limiting groove 3 is provided at both ends of the inner side of the guide rail 2. A movable bracket 4 is slidably installed on the inner side of the guide rail 2. Limiting sliders 5 that are adapted to the limiting grooves 3 are fixedly connected to both sides of the movable bracket 4. A ball head sleeve 6 is fixedly connected to the inner side of the movable bracket 4. A ball head 7 is movably installed inside the ball head sleeve 6. A handle 8 located below the worktable 1 is fixedly installed at the bottom of the ball head 7.

[0025] The specific usage process is as follows: Before starting grinding, place the workpiece body 15 on the workpiece top rod 14, hold it with one hand, and rotate the locking ring 12 downwards with the other hand. During the downward movement of the locking ring 12, it will squeeze the two support rods 11 and rotate them into the movable groove 10. When the lower end of the support rod 11 is squeezed into the movable groove 10 by the locking ring 12, the upper end of the support rod 11 will rotate outwards. Then, the upper ends of the two support rods 11 will support the workpiece body 15 from two opposite directions. It should be noted that during the production process, the inner wall of the workpiece body 15 is not completely flat. Therefore, the ends of the two outwardly extending support rods 11 can be engaged with the inner wall of the workpiece body 15, or in other words, the ends of the support rods 11 can be engaged with the uneven angles of the inner wall of the workpiece body 15, thereby fixing the workpiece body 15 in place. Simultaneously, when the workpiece body 15 is being ground, the workpiece push rod 14 also provides support, preventing the workpiece body 15 from being pushed downwards by the grinding wheel 17. It should be noted that a magnet can also be embedded in the end of the workpiece push rod 14 to attract the workpiece body 15. This, combined with the fixation of the workpiece body 15 by the two support rods 11, can... To improve the stability of the workpiece body 15 during the grinding process, the workpiece body 15 is positioned when the locking ring 12 cannot be turned. Furthermore, the two support rods 11 will not easily move under the locking action of the locking ring 12. The user can then hold the handle 8 to control the workpiece body 15 to contact the grinding wheel 17 for grinding. The handle 8 is fixedly connected to the ball head 7, enabling the ball head 7 to move within the ball head sleeve 6. It should be noted that the ball head 7 is installed at the center of the ball head sleeve 6; therefore, the ball head 7 cannot move in either the vertical or horizontal direction, but can only rotate within the ball head sleeve 6. It can rotate freely within a 360-degree range, allowing the user to control the workpiece body 15 to contact the grinding wheel 17 at any angle for grinding. For slightly lower positions, the workpiece body 15 can be moved upwards by raising the handle 8 and the movable bracket 4, ensuring that even slightly lower areas of the workpiece body 15 can be ground. Similarly, slightly higher areas can be adjusted in this way. When the movable bracket 4 moves up and down within the guide rail 2, the limiting slider 5 slides within the corresponding limiting groove 3 to guide and limit the movement trajectory of the workpiece body 15, providing assistance and convenience for the user's grinding work. Figure 3As shown, the end of the limiting slider 5 is bent outward. Therefore, when the user lowers the movable bracket 4, the limiting slider 5 will hook onto the guide rail 2, preventing the movable bracket 4 from falling off the guide rail 2. When moving upward, the user can control the movement distance. Under normal circumstances, the maximum upward movement distance of the workpiece body 15 is the height at which it contacts the grinding wheel 17. The design length of the limiting slider 5 is greater than this distance, so a structure that can rotate 360 ​​degrees is adopted. Combined with a structure that can adjust the height in real time, this provides the user with a sufficiently stable fulcrum during work, enabling precise control of the grinding details of the workpiece, reducing the likelihood of defective parts, improving the grinding quality and efficiency of the workpiece, and also improving the safety of the workers.

[0026] The top of the ball head 7 is fixedly connected to a support rod 9, and the top of the support rod 9 is fixedly connected to a workpiece push rod 14.

[0027] Specifically, the workpiece is placed on the top of the workpiece push rod 14, so that the workpiece push rod 14 can support the workpiece body 15 and fix the workpiece body 15. At the same time, when the workpiece body 15 is being ground, the workpiece push rod 14 will also support the workpiece body 15, so that the workpiece body 15 will not be pushed downward by the grinding wheel 17.

[0028] Both sides of the support rod 9 are provided with movable grooves 10. A support rod 11 is rotatably installed inside the movable groove 10. A spring 13 is fixedly connected to one side of the movable groove 10. The end of the spring 13 away from the support rod 11 is fixedly connected to the inner wall of the movable groove 10. The top of the workpiece top rod 14 is on the workpiece body 15. The upper ends of the two support rods 11 extend into the inner side of the workpiece body 15 and abut against the inner wall of the workpiece body 15.

[0029] The support rod 9 is threaded with a locking ring 12, and both support rods 11 are located inside the locking ring 12.

[0030] A grinding device body 16 is detachably installed on one side of the workbench 1. A grinding wheel 17 is fixedly installed at the output end of the grinding device body 16, and the workpiece body 15 is located below the grinding wheel 17.

[0031] The outer side of the grinding wheel 17 is covered with a protective cover 18 that is fixedly installed on the grinding device body 16, and a dust suction pipe 19 is connected to one side of the protective cover 18.

[0032] Specifically, the protective cover 18 and the suction pipe 19 are designed to protect the user from the flying sparks generated during the polishing process, thereby improving the user's work safety. The suction pipe 19 is used to connect to the vacuuming equipment, so that the debris generated during polishing can be sucked away and collected, providing assistance and convenience for the user's cleaning work.

[0033] In summary, the rotating device for grinding the semi-circular front cover, with its 360-degree rotatable structure and adjustable height, provides users with a stable fulcrum during operation. This allows for precise control over the grinding details of the workpiece, reducing the likelihood of defective parts, improving grinding quality and efficiency, and enhancing worker safety.
