The invention aims to overcome the defects of the prior art, and provides a sewing machine tool rest center hole machining tool which clamps a workpiece through a rotating block and turns over the workpiece through the rotation of the rotating block, so that the hole machining precision is improved.
The technical scheme adopted by the invention is as follows:
the utility model provides a sewing machine knife rest centre bore processing frock which characterized in that: the clamp comprises a clamp seat, a rotating block and a locking cap, wherein the rotating block is rotatably arranged at the front end of the clamp seat, a vertical groove is formed in the transverse middle of the rotating block, a cylinder of a workpiece to be machined is clamped in the groove, a flat plate of the workpiece to be machined is pressed on the upper end surface or the bottom surface of the rotating block, and the locking cap is used for locking the rotating block after rotation.
And a pressing block is arranged at the front end of the rotating block, and one side end of the pressing block presses the cylinder in the slot.
Furthermore, a rotating shaft is arranged in the middle of the rear end face of the rotating block, penetrates through the clamp seat and extends to the outer edge of the end part of the rear end of the clamp seat to be meshed and sleeved with the locking cap.
Furthermore, two sides of the rotating block are provided with symmetrical limiting grooves, and limiting rods are arranged on the front end face of the clamp seat aligned with the limiting grooves.
The invention has the advantages and positive effects that:
according to the invention, a cylinder of a workpiece to be processed is embedded in the open slot of the rotating block through the pressing block, a flat plate of the workpiece to be processed is pressed on the upper end surface or the bottom surface of the rotating block, limiting grooves are arranged on two sides of the rotating block, and a limiting rod is arranged on the front end surface of the clamp seat aligned with the limiting grooves. When the device is used, the cylinder is firstly embedded into the groove, the flat plate is pressed on the upper end face of the rotating block, the pressing block is locked, the locking cap is adjusted to position the rotating block, a hole is formed in the flat plate, then the locking cap is loosened to enable the rotating block to rotate 180 degrees, then the locking cap is locked, and a hole is formed in the bottom face of the cylinder. The workpiece is located in the middle of the rotating block, the limiting groove and the limiting rod are matched with each other, the rotating block is kept in the machining position after rotating, the positions of the two holes are accurate, machining precision is high, operation workers can operate the rotating block conveniently, and time and labor are saved.

Detailed Description
The present invention is further illustrated by the following examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the invention.
The invention discloses a sewing machine knife rest center hole processing tool, which is characterized in that as shown in figures 1-4: the clamp comprises a clamp seat 2, a rotating block 8 and a locking cap 12, wherein the front end of the clamp seat is rotatably provided with the rotating block, a vertical groove 7 is formed in the transverse middle of the rotating block, a cylinder 5 of a workpiece to be machined is clamped in the groove, a flat plate 4 of the workpiece to be machined is pressed on the upper end surface or the bottom surface of the rotating block, and the locking cap driven by a handle 9 is used for locking the rotating block after rotation.
In this embodiment, a ball member 10 is attached to the outer end of the handle, and a base 11 is provided on the bottom surface of the jig base. A pressing block 1 is arranged at the front end of the rotating block, and an end part 6 on one side of the pressing block presses the cylinder in the groove.
The middle of the rear end face of the rotating block is provided with a rotating shaft 16, and the rotating shaft penetrates through a through hole 15 arranged on the clamp seat and then extends to the outer edge of the end part 13 at the rear end of the clamp seat to be meshed and sleeved in an inner hole 14 of the locking cap.
In order to ensure the rotating precision of the rotating block, two sides of the rotating block are provided with symmetrical limiting grooves 18, and a limiting rod 17 is arranged on the front end face of the clamp seat aligned with the limiting grooves. The preferred scheme is as follows: the limiting groove is internally provided with a cross rod 19, and the rotating block is limited by the contact of the cross rod and the limiting rod.
