Problems solved by technology
Using the five-axis CNC machining center to process high-precision oblique holes, only one clamping of the oblique hole processing parts can complete the processing of all oblique holes on the parts. It has the advantages of convenient processing, high precision of oblique hole machining positions and high efficiency. The purchase cost of the five-axis CNC machining center is very high (one needs several million yuan), so it is unaffordable for general processing and manufacturing plants
Using a four-axis CNC machining center to process high-precision inclined holes, although it can reduce the purchase cost of equipment compared with a five-axis CNC machining center, it needs to be used with fixtures to realize the machining of inclined holes, and the machined parts need to be rotated for each inclined hole. Angle, resulting in repeated clamping of the processed parts, consuming a lot of time for clamping and alignment, not only complicated operation, but also low processing efficiency

Disclosed is a drilling jig for machining high-precision oblique holes. The drilling jig comprises a jig body, bushings, drilling bushings, a positioning pin and a pressing piece. The jig body is provided with a central hole. An annular groove used for being combined with an oblique hole machining part is formed around the central hole. Jig body fixing holes are formed around the annular groove. Bushing mounting holes are formed in the one side wall or the two side walls of the annular groove, wherein the number of the bushing mounting holes and the number of the required to-be-machined oblique holes in the oblique hole machining part are same, the positions of the bushing mounting holes correspond to the positions of the required to-be-machined oblique holes in the oblique hole machiningpart, and oblique angles of the bushing mounting holes and oblique angles of the required to-be-machined oblique holes in the oblique hole machining part are same. A positioning pin mounting hole is formed in the bottom wall of the annular groove. The number of the bushings and the number of the required to-be-machined oblique holes are same. Each bushing is mounted in the corresponding bushing mounting hole and fixedly connected with the jig body through pressing screws. The number of the drilling bushings and the number of the bushings are same. Each drilling bushing is fixed into the corresponding bushing. The positioning pin is used for positioning when the jig body is combined with the oblique hole machining part. The pressing piece is used for fixed connecting of the jig body and theoblique hole machining part. The drilling jig for machining the high-precision oblique holes can be matched with a radial drilling machine for machining of the high-precision oblique holes.
Description
technical field [0001] The invention belongs to the field of oblique hole processing of parts, in particular to a drilling mold for processing high-precision oblique holes on parts. Background technique [0002] The machining of high-precision inclined holes on parts is generally completed on CNC machine tools. The commonly used CNC machine tools are five-axis CNC machining centers or four-axis CNC machining centers. Using the five-axis CNC machining center to process high-precision oblique holes, only one clamping of the oblique hole processing parts can complete the processing of all oblique holes on the parts. It has the advantages of convenient processing, high precision of oblique hole processing position and high efficiency. The purchase cost of the five-axis CNC machining center is very high (one needs several million yuan), so it is unaffordable for general processing and manufacturing plants. Using a four-axis CNC machining center to process high-precision inclined...
