[0041] The utility model will be further described in the specific embodiment below, refer to Figure 1 -7:

[0042] A high-precision honing and reaming machine for machining the inner hole of a sewing machine sleeve includes a frame 1. The frame 1 is sequentially provided with a feeding station, a honing station, a multi-stage reaming station, and a feeding device for moving the workpiece from the previous station to the next station. The honing station is provided with a clamping assembly for fixing the workpiece and a honing device located above the clamping assembly. The honing device includes a honing cutter bar 2 driven to rotate by a power device and a honing strip 3 disposed on the honing cutter bar 2. A push rod 4 is slidably disposed inside the honing cutter bar 2 to push the honing strip 3 to move outward. The push rod 4 is driven by a drive device to move along the axial direction of the honing cutter bar 2. The reaming station is provided with a clamping assembly for fixing the workpiece and a reaming device located above the clamping assembly. The reaming device includes a reamer 5 driven to rotate by a power device.

[0043] The working principle of this utility model is as follows: Figures 1-7 As shown, the feeding device moves the workpiece from the previous station to the next station. The fixture assembly of the honing station clamps the workpiece. The power unit one drives the honing bar 2 to rotate, and the drive unit one drives the push rod 4 to move down and push the honing strip 3 to move outward, performing rough honing on the inner hole of the workpiece. After honing, the workpiece is moved to the next reaming station via the feeding device. The fixture assembly of the reaming station clamps the workpiece, and the power unit two drives the reamer 5 to rotate, performing fine reaming on the inner hole of the workpiece.

[0044] This invention sets up a honing station and multiple reaming stations on a single device, and moves the workpiece from the previous station to the next station through a feeding device.

This leads to increased processing time and costs, and low production efficiency.

[0046] To avoid rework due to insufficient machining caused by worn honing tools, the system also includes a controller and a detection device for measuring the inner hole size of the workpiece at the honing station. The detection device, power unit one, drive unit one, power unit two, and feeding device are all electrically connected to the controller.
