When the abrasives in the grinding tool are consumed, a new grinding tool needs to be replaced. When the grinding head needs to be replaced, it is often necessary to manually disassemble the original grinding tool and then install a new one. This replacement method is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0021] The present invention is described in detail below in conjunction with specific embodiments.

[0022] In the present utility model, when directional words appear, they are used to facilitate the description of the utility model and simplify the description, rather than to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present utility model.

[0023] In the present invention, unless otherwise specified and limited, when terms such as "disposed on", "connected" and "connected" appear, these terms should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or the two elements can be internally connected. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figures 1 to 3 As shown, a grinding head assembly of a fully automatic outer diameter mirror polishing machine includes a mounting seat 10, a grinding head seat 20, a grinding tool 30 and a first telescopic cylinder 24.

[0025] The grinding head seat 20 is connected to the bottom of the mounting seat 10. A fixed side plate 21 and a movable side plate 22 are respectively provided on both sides of the grinding head seat 20. A coupling sleeve 23 is provided on the fixed side plate 21 and the movable side plate 22. A connecting shaft is provided at both ends of the grinding tool 30, and its two ends are respectively connected to the coupling sleeves 23 on the fixed side plate 21 and the movable side plate 22. The first telescopic cylinder 24 is arranged on the grinding head seat 20 and is located between the fixed side plate 21 and the movable side plate 22. The telescopic end of the first telescopic cylinder 24 is connected to the movable side plate 22.

[0026] The movable side plate 22 is driven to telescopically move by the first telescopic cylinder 24, so as to change the distance between the fixed side plate 21 and the movable side plate 22, and the end of the mold 30 can be clamped or released through the coupling sleeve 23 on the fixed side plate 21 and the movable side plate 22.

[0027] In a specific implementation, the mounting seat 10 is used to be connected to the three-axis moving mechanism 1 on the fully automatic outer diameter mirror polishing machine equipment, and the grinding head assembly is controlled by a numerical control program to clamp and connect the end of the grinding tool 30 to grind and polish the workpiece, or to release the connection to replace the grinding tool 30, thereby achieving the purpose of automatically replacing the grinding head, saving tool changing time, and improving grinding and polishing efficiency.

[0028] In this embodiment, a driving motor 11 is provided on the mounting seat 10, and a coupling sleeve 23 is rotatably arranged on the fixed side plate 21 and the movable side plate 22 through a bearing. One end of the coupling sleeve 23 on the fixed side plate 21 is connected to the output end of the driving motor 11 through a synchronous pulley and a belt drive.

[0029] In a specific implementation, the grinding tool 30 is a long block structure, and grinding materials can be set on the surface of the grinding tool 30. When the grinding materials on a certain surface of the grinding tool 30 are consumed, the driving motor 11 drives the coupling sleeve 23 to rotate through the synchronous pulley and the belt, thereby driving the consumed grinding material surface on the grinding tool 30 to rotate and replace it with the unconsumed grinding material surface, and the workpiece can continue to be ground to reduce the replacement frequency of the grinding tool 30 and realize continuous grinding of the workpiece.

[0030] In addition, the drive motor 11 can also drive the coupling sleeve 23 to rotate through the synchronous pulley and belt, thereby driving the grinding tool 30 to rotate, changing the grinding angle of the grinding tool relative to the workpiece being processed, and can be used to follow the taper or spherical surface formed by the diameter change of the workpiece during grinding to ensure that the grinding material achieves the best grinding effect.

[0031] In this embodiment, the inner hole of the coupling sleeve 23 on the fixed side plate 21 is a directional inner hole, and the coupling sleeve 23 on the movable side plate 22 is a circular inner hole. The shapes of the connecting shafts at both ends of the mold 30 are adapted to the inner holes of the coupling sleeves 23 on the fixed side plate 21 and the movable side plate 22, thereby preventing the mold 30 from idling or slipping when the mold 30 is driven to rotate.

[0032] In this embodiment, the grinding head seat 20 is provided with a guide rod 25 penetrating the movable side plate 22, one end of the guide rod 25 is connected to the fixed side plate 21, and the other end of the guide rod 25 is provided with a support seat 26 connected to the grinding head seat 20. Through the provision of the guide rod 25, the first telescopic cylinder 24 can drive the movable side plate 22 to move horizontally more smoothly, so that the two ends of the grinding tool 30 can be clamped and connected accurately.

[0033] In this embodiment, a workpiece loading and unloading mechanism 40 is provided at the front side of the mounting seat 10. The workpiece loading and unloading mechanism 40 can be connected to the three-axis moving mechanism 1 on the fully automatic outer diameter mirror polishing machine together with the grinding head assembly, which can reduce the number of separate moving mechanisms required for the workpiece loading and unloading mechanism 40 and reduce the equipment manufacturing cost. In addition, in order to avoid structural interference caused by the workpiece loading and unloading mechanism 40 during the processing of the grinding head assembly, the lower end of the workpiece loading and unloading mechanism 40 is higher than the lower end of the grinding head seat 20.

[0034] Specifically, the workpiece loading and unloading mechanism 40 includes a second telescopic cylinder 41 and an air gripper 42. The second telescopic cylinder 41 is vertically arranged on the mounting seat 10, and the air gripper 42 is arranged at the telescopic end of the second telescopic cylinder 41 through a connecting seat. The air gripper 42 can be directly driven by the second telescopic cylinder 41 to move up and down, and the workpiece to be processed can be clamped or released, thereby improving the speed of clamping or releasing the workpiece.

[0035] The utility model provides a grinding head assembly of a fully automatic outer diameter mirror polishing machine. Compared with the prior art, the mounting seat 10 is used to connect the three-axis moving mechanism 1 on the polishing machine equipment. The grinding head assembly is controlled by a numerical control program. The first telescopic cylinder 24 arranged on the grinding head seat 20 drives the movable side plate 22 to telescopically move, thereby changing the distance between the fixed side plate 21 and the movable side plate 22, and through the coupling sleeve 23 on the fixed side plate 21 and the movable side plate 22, the end of the grinding tool 30 can be clamped and connected to grind and polish the workpiece, or the connection can be released to replace the grinding tool 30, thereby achieving the purpose of automatically replacing the grinding head, saving tool changing time, and improving grinding and polishing efficiency.

[0036] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
