Background
The number of the main shafts of the machine tool is more than 1, the machine tool is called a multi-main-shaft machine tool, and a plurality of parts can be simultaneously machined by using the multi-main-shaft machine tool, and the machine tool is called multi-main-shaft machining. The quality control of multi-spindle machining mainly aims at part clamping, and is characterized in that parts and a clamp are fixedly held on a workbench through a key groove of a machine tool workbench, the Y-direction spacing of each part is ensured to be consistent with the spacing of a spindle, and the X-direction spacing of each part needs to be consistent. The Y-direction distance can be positioned and controlled through a key groove of a machine tool workbench. The X direction can not be positioned, and the clamp can only be manually knocked by a heavy object to move for adjustment, which wastes time and labor. When many main shafts processing clamping parts, in order to guarantee several parts X to unanimous, adopt the position of manual adjustment anchor clamps to guarantee X to the uniformity, mainly have following shortcoming: the labor intensity is high; the device has low working efficiency.

The technical solution of the invention is as follows:
a quick positioning method for multi-spindle machining comprises the following steps:
respectively placing the positioning blocks corresponding to the number of the main shafts into key grooves of a machine tool workbench, wherein the distance between the positioning blocks is equal to that between the main shafts;
placing a connecting rod perpendicular to the axis of the key groove on the key groove;
adjusting the position of the positioning block to enable the positioning hole in the positioning block to be superposed with the positioning hole in the connecting rod;
connecting the positioning block with the positioning hole on the connecting rod by using a positioning pin;
fixing the positioning block in the key groove of the machine tool workbench;
removing the positioning pin and the connecting rod;
and the fixture is positioned and clamped on the workbench by using the positioning hole and the key slot on the positioning block.
The positioning block is provided with a screw hole and is fixed in a key groove of a machine tool workbench through a screw.
The connecting rod is connected with the positioning blocks, holes are formed in the connecting rod, and the distance between the holes is equal to the distance between the main shafts.
The key groove of the machine tool workbench is a T-shaped groove.
The positioning pins and the connecting rods are used for controlling the positioning blocks to be consistent in the X direction, the positioning blocks are fixed by screws respectively, the positioning pins and the connecting rods are removed, then one end of the clamp is positioned through the positioning holes in the positioning blocks, and the other end of the clamp is positioned through the key slot. The number of the positioning blocks is equal to that of the spindles, and the distance between the positioning holes on the connecting rod is equal to that of the spindles.
