Technical Field

[0001] This utility model relates to the field of honing technology, specifically a clamping assembly for a vertical honing machine. Background Technology

[0002] like Figure 1 The image shows the rotor of a rotary engine. Rotary engines use rotational motion to achieve combustion and power output, and are characterized by simple structure, high power density, smooth operation, and high-speed capability. Currently, the main research and applications of rotary engines are concentrated in some specialized fields, such as drones and small generators. The rotor, a key component, has multiple holes (7 / 9 / 11, etc.) evenly distributed around its circumference. These holes are used for lubrication, weight reduction, and cooling, and require high precision, thus necessitating honing. With the rapid development of the drone industry, the demand for rotors is constantly increasing, and the demand for honing the rotor holes is also increasing accordingly.

[0003] When the rotor is processed on the honing machine, the stability requirements are extremely high. If it is not stable enough and displacement occurs, it will affect the quality of the rotor, and may even lead to the scrapping of the rotor.

[0004] Therefore, developing a device that can stabilize the rotor during processing is an urgent task for those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a clamping assembly for a vertical honing machine to solve the problems mentioned in the background art.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a clamping assembly for a vertical honing machine, including a clamping base plate 1 and a clamping base 2 detachably connected to the clamping base plate 1. For example, the clamping base plate 1 and the clamping base 2 are connected by bolts 4. The clamping base plate 1 has screw holes for easy connection to the honing machine. A detachable workpiece positioning assembly 3 is provided at the upper end of the clamping base 2. The clamping base 2 includes an upper cover 21 and a lower cover 22. A hollow cylindrical seat 23 is provided between the upper cover 21 and the lower cover 22. The lower cover 22 has symmetrical first cut edges 24, and the upper cover 21 has symmetrical second cut edges 25. The first cut edges 24 and the second cut edges 25 are arranged in the same direction, which can reduce processing costs and reduce the suction force between the workpiece and the connecting parts, facilitating disassembly. The workpiece positioning assembly 3 includes a positioning base plate 31, a positioning center plate 33, and a clamping end cap 5. The positioning base plate 31 is detachably connected to the upper cover 21, and the clamping end cap 5 is threadedly connected to the positioning center plate 33.

[0025] In one embodiment of this utility model, the upper end face of the upper cover 21 is provided with a rhomboid positioning pin 26 and a circular positioning pin 27, and the bottom end face of the positioning base plate 31 is provided with holes that cooperate with the rhomboid positioning pin 26 and the circular positioning pin 27. The rhomboid positioning pin 26 and the circular positioning pin 27 enable a stable and correct connection between the positioning base plate 31 and the clamp base 2.

[0026] In one embodiment of this utility model, a circular groove 32 is provided at the center of the upper end face of the positioning base plate 31. A positioning center plate 33 is provided on the positioning base plate 31, and the positioning center plate 33 covers the circular groove 32. The positioning center plate 33 is connected to the positioning base plate 31 by bolts, and the peripheral wall of the positioning center plate 33 is provided with threads 34. Correspondingly, the inner wall of the pressing end cover 5 is provided with internal threads that cooperate with the threads 34, and the pressing end cover 5 is threadedly connected to the positioning center plate 33 by the threads 34.

[0027] In one embodiment of this utility model, the positioning center plate 33 is connected to the positioning base plate 31 by screws.

[0028] In one embodiment of this utility model, a positioning pin 35 is provided at the center of the positioning center plate 33. The upper end of the positioning pin 35 protrudes above the positioning center plate 33. During processing, the center hole of the workpiece is inserted into the positioning pin 35. One or two suction pins 6 are provided circumferentially around the positioning pin 35. The suction pins 6 are inserted into the holes around the workpiece, so that the workpiece can remain stable during processing and will not rotate.
