[0002] Machining refers to the process of changing the external dimensions or performance of a workpiece through a mechanical device. It can be divided into cutting and pressure processing according to the difference in processing methods. In the machining process, any process that changes the shape, size, position and properties of the production object to make it a finished product or semi-finished product is called a process.

[0003] In the existing technology, the workpiece needs to be fixed with the help of a fixture during turning to avoid deviation and tilting during the processing. However, most of the existing processing technologies use traditional turning and milling processes. The turning and milling of oxidized aluminum parts are prone to scratches and the shape and size are difficult to guarantee. In addition, the fixture displacement speed is inconvenient to control during clamping, which easily causes scratches on the appearance. In view of this, we propose a cavity cover turning tool. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The cavity cover turning tool, when clamping the workpiece, places the workpiece inside the placement groove, and then uses the driving component to drive the main body to move as a whole. When the main body moves, it will simultaneously drive the connecting rod and the limit cylinder to move. When the limit cylinder moves, the clamping cylinder is used to drive the clamping plate and the rubber plate to move. After the clamping plate moves, it approaches the workpiece but does not contact the workpiece. At this time, the fine adjustment component is used to drive the threaded rod to rotate. After the threaded rod rotates, the fine adjustment component is used again to drive the clamping cylinder to move slowly, and then drive the clamping plate and the rubber plate to move. After the clamping plate and the rubber plate move, they contact the workpiece and complete the clamping. Through the above structure, the workpiece can be clamped more stably and reliably, avoiding damage to the workpiece caused by excessive travel distance. Fine adjustment can effectively avoid surface scratches and improve the overall part qualification rate.

[0015] (2) The cavity cover turning tool uses the threaded sleeve and the fixed rod to drive the clamping cylinder to move horizontally when the threaded rod rotates. At the same time, after the fine positioning is completed, the displacement cylinder is rotated and the threaded groove is used to make the displacement cylinder drive the fixed plate to move as a whole. After the fixed plate moves, it contacts the right side surface of the main body. Through the above structure, after the fine adjustment is completed, the fixed plate can be used to record. When the clamping is repeated later, the fixed plate can be used to limit the main body to achieve the purpose of fine positioning, thereby avoiding damage to the outer surface of the part.

The driving assembly described in the article is an existing structure (such as pushing Rod motor, cylinder, hydraulic telescopic rod, etc.) will not be described in detail here. When clamping the workpiece, the workpiece is placed inside the placement groove, and then the driving assembly is used to drive the main body 2 to move as a whole. When the main body 2 moves, it will synchronously drive the connecting rod 4 and the limit cylinder 6 to move. When the limit cylinder 6 moves, the clamping cylinder 8 is used to drive the clamping plate 9 and the rubber plate 10 to move. After the clamping plate 9 moves, it approaches the workpiece but does not contact the workpiece. At this time, the fine adjustment assembly is used to drive the threaded rod 7 to rotate. After the threaded rod 7 rotates, the fine adjustment assembly is used again to drive the clamping cylinder 8 to move slowly, thereby driving the clamping plate 9 and the rubber plate 10 to move. After the clamping plate 9 and the rubber plate 10 move, they contact the workpiece and complete the clamping. Through the above structure, the workpiece can be clamped more stably and reliably, avoiding damage to the workpiece caused by excessive travel distance. Fine adjustment can effectively avoid surface scratches and improve the overall part qualification rate.

[0025] Furthermore, a threaded sleeve 12 of the fine adjustment group is threadedly sleeved on the outer surface of the threaded rod 7. The outer surface of the threaded sleeve 12 is fixedly connected to a fixing rod 13. The fixing rod 13 is fixedly connected to the inner wall of the clamping cylinder 8 through a sliding groove 11. The fixing rod 13 is slidably connected to the sliding groove 11. A rotating sleeve 14 is rotatably connected between the connecting rod 4 and the limiting cylinder 6. The inner wall of the rotating sleeve 14 is fixedly connected with teeth 15. The outer surface of the threaded rod 7 is fixedly connected with a second tooth 16. The connecting rod 4 and the inner wall of the limiting cylinder 6 are respectively fixedly connected with mounting plates 17. The side surfaces of the two mounting plates 17 are rotatably connected with an external tooth tube 18. The outer surfaces of the external tooth tube 18 are respectively meshed with the teeth 15 and the second tooth 16. The left surface of the cover plate 3 is fixedly installed with a limiting rod 19 by bolts. The left end of the limiting rod 19 slides through the left surface of the main body 2. The outer surface of the limiting rod 19 is provided with a threaded groove 20. The outer surface is provided with a displacement cylinder 21 through a threaded sleeve of a thread groove 20, and the left surface of the displacement cylinder 21 is fixedly connected to a fixed plate 22. By rotating the rotating sleeve 14, the teeth 15 are used to drive the outer tooth tube 18 to rotate. After the outer tooth tube 18 rotates, the second teeth 16 are used to drive the threaded rod 7 to rotate. Since the diameter of the outer tooth tube 18 is smaller than the threaded rod 7, a certain deceleration effect is formed. At the same time, when the threaded rod 7 rotates, the threaded sleeve 12 and the fixed rod 13 are synchronously used to drive the clamping cylinder 8 to move horizontally. At the same time, after the fine positioning is completed, by rotating the displacement cylinder 21, the threaded groove 20 is used to make the displacement cylinder 21 drive the fixed plate 22 to move as a whole. After the fixed plate 22 moves, it contacts the right surface of the main body 2. Through the above structure, after the fine adjustment is completed, the fixed plate 22 can be used to record. When the clamping is repeated in the subsequent time, the fixed plate 22 can be used to limit the main body 2 to achieve the purpose of fine positioning, thereby avoiding damage to the outer surface of the part.

[0026] Working principle: When clamping the workpiece, the workpiece is placed inside the placement groove, and then the driving component is used to drive the main body 2 to move as a whole. When the main body 2 moves, it will synchronously drive the connecting rod 4 and the limiting cylinder 6 to move. When the limiting cylinder 6 moves, the clamping cylinder 8 is used to drive the clamping plate 9 and the rubber plate 10 to move. After the clamping plate 9 moves, it approaches the workpiece but does not contact the workpiece. At this time, the fine adjustment component is used to drive the threaded rod 7 to rotate. After the threaded rod 7 rotates, the fine adjustment component is used again to drive the clamping cylinder 8 to move slowly, thereby driving the clamping plate 9 and the rubber plate 10 to move. The clamping plate 9 and the rubber plate 10 are in contact with each other. After the movement, the plate 10 contacts the workpiece, thereby completing the clamping. By rotating the rotating sleeve 14, the teeth 15 are used to drive the outer tooth tube 18 to rotate. After the outer tooth tube 18 rotates, the second teeth 16 are used to drive the threaded rod 7 to rotate. Since the diameter of the outer tooth tube 18 is smaller than the threaded rod 7, a certain deceleration effect is formed. At the same time, when the threaded rod 7 rotates, the threaded sleeve 12 and the fixed rod 13 are synchronously used to drive the clamping cylinder 8 to move horizontally. At the same time, after the fine positioning is completed, by rotating the displacement cylinder 21, the thread groove 20 is used to make the displacement cylinder 21 drive the fixed plate 22 to move as a whole. After the fixed plate 22 moves, it contacts the right surface of the main body 2.

Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
