Description

Technical Field

[0001] This utility model belongs to the field of CNC lathes, specifically relating to a pneumatic grinding tool that is externally mounted on the turret of a CNC lathe. Background Technology

[0002] Most existing CNC lathes on the market are not equipped with a power turret due to cost reasons, which limits the machining range of CNC lathes. Some workpieces need to be processed in multiple steps. The multiple loading and unloading during the machining process will affect the positioning accuracy of the workpiece. Especially for workpieces that require grinding and chamfering of multiple parts, outsourcing is often necessary. Outsourcing is expensive, time-consuming and costly, and will also seriously affect the machining efficiency of the workpiece.

[0003] Therefore, how to provide a pneumatic grinding tool that can be externally mounted on the turret of a CNC lathe has become a problem that needs to be considered by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a pneumatic grinding tool that is externally mounted on the turret of a CNC lathe. It drives different grinding heads to grind the workpiece by means of pneumatic means, without having to remove the workpiece. This not only improves the accuracy of workpiece processing, but also improves the processing efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pneumatic grinding fixture externally mounted on a CNC lathe turret includes a base mounted on a rodless cylinder of the turret. The base has a stepped hole and an air inlet at its end. A pneumatic connector is installed in the air inlet. The stepped hole communicates with the air inlet. A clamping body, a bearing, and a limiting ring are disposed within the stepped hole. The clamping body is used to hold the grinding head. A drive blade is located at the end of the clamping body. The clamping body is rotatably mounted in the stepped hole via the bearing. The limiting ring is rotatably fitted onto the clamping body and is mounted together with the clamping body in the stepped hole to prevent the clamping body from dislodging from the stepped hole.

[0007] Furthermore, a tapered mounting hole is provided on the inner side of the front end of the clamp body, and an external thread is provided on the outer side of the front end of the clamp body. A detachable chuck is threadedly connected to the outer side of the front end of the clamp body, and a clamping sleeve is rotatably connected to the detachable chuck.

[0008] Furthermore, the top end of the detachable chuck is provided with an annular groove, and the top end of the clamping sleeve is provided with an annular protrusion corresponding to the annular groove, the annular protrusion being rotatably connected in the annular groove.

[0009] Furthermore, the clamping sleeve has a through mounting hole inside, and an annular groove is provided at the front end of the through mounting hole, in which a rubber ring is installed.

[0010] Furthermore, the driving blade is a spiral blade or a convex blade.

[0011] Furthermore, the fixture body has an arc-shaped groove at the mounting location of the drive blade, and the stepped hole has a through hole corresponding to the arc-shaped groove for gas discharge.

[0012] The beneficial effects of this utility model are as follows: This utility model, when paired with a CNC lathe, utilizes helical or convex blades to pneumatically drive the main body, achieving rapid rotation and driving the grinding head at the machining end for grinding operations, such as: concentric grinding of inner and outer diameters, parabolic or irregular curved outer diameter grinding, and end face perpendicularity and bottom perpendicularity grinding. Regardless of the inner and outer appearance and end face shape, as long as the CNC lathe program can run along the path, this utility model can perform grinding operations, avoiding frequent disassembly of the workpiece. Grinding can be done directly without removing the workpiece, completing the process in one go and improving the accuracy of workpiece machining. Attached Figure Description
