Description

Multiple spindle boring machine

The present invention relates to a multi-axis boring device for simultaneously processing a plurality of holes (hole) in the plate, more specifically to improve the efficiency of the hole machining operation by processing a plurality of holes in the plane and side of the plate at the same time and the workload It relates to a multi-axis boring device that can reduce the.

In general, in order to manufacture furniture and the like using a plate, a groove or a hole is processed in one plate and a protrusion corresponding to the groove or a hole is formed in the other plate. Then, after joining the grooves or holes and the projections of the plate material and by applying the bonding portion with an adhesive or the like to produce a plate-like furniture.

Conventionally, a plurality of grooves or holes have been processed in a plate by hand using a chisel and a hammer. However, as a result of such manual work, it took considerable time to process the grooves or holes, and it did not sufficiently satisfy the demand for keeping the groove and hole formation gap constant. As a result, the processing of grooves or holes by hand was inefficient.

On the other hand, in order to solve the problem of hole processing in the manual work was made, but at the same time there was a problem that can not perform a smooth operation for processing a plurality of holes. In addition, the hole machining operation was not effective in the case where manual work is involved in such a machining facility. For example, when the plate is set in the machining facility by the operation of the screw handle, a lot of time was required for the setting operation. In addition, it takes a lot of time because the screw fixing method is used to fix the processing equipment to hole the plate. In particular, the side processing operation of the hole in the side of the plate required careful attention to the operator.

The present invention is devised to solve the conventional problems as described above, by simultaneously processing a plurality of holes on the side and plane of the plate at regular intervals to reduce the load of the hole processing operation and also to improve the work efficiency The purpose is to provide a multi-axis boring device.

In addition, another object of the present invention is to drive the adhering unit of the plate in a one-touch setting method and to drive the left and right movement of the clamp in a bearing method to fix the time required to set the plate in the hole processing equipment and processing equipment The purpose is to provide a multi-axis boring device that can effectively reduce the time required when.
