Description

Technical Field

[0001] The utility model relates to the technical field of drilling jig tooling for milling machines, in particular to a drilling jig tooling for milling machines. Background Art

[0002] like Figure 1 As shown, this workpiece includes a circular body 1, a groove body 2 is provided in the middle of the circular body, and the two ends are respectively a first end 3 and a second end 4; the outer diameter of the second end is smaller than the outer diameter of the circular body, and an assembly hole 5 is provided on its outer circumference; a connecting seat 6 is provided on the groove body, and the connecting seat has processing features such as a cylinder, a waist groove, a tooth hole, and a chamfer; the assembly holes are distributed along the circumference of the outer circumference of the second end.

[0003] In the existing processing procedures, the bar is first processed into the contours of the circumferential body, the first end and the second end using a lathe, and then the CNC four-axis machining machine is used for full-automatic processing. Each machine is operated by one person per shift to process 12 pieces. When the order is urgent, the delivery time is short. The CNC four-axis machine tools and four-axis operators are limited. According to the existing processing method, the cost is high and the delivery time cannot be met. For this reason, the manufacturer has developed a corresponding CNC three-axis fixture to reduce the technical requirements of personnel, so that the operator can operate the three-axis CNC with one person and multiple machines to process the features at different positions on the workpiece in batches, thereby improving the production capacity. However, there is an angle between the circumferential distribution surface of the assembly hole 5 on the second end 4 of the workpiece and the end face of the slot body 2. When processing the assembly hole, it is still necessary to repeatedly clamp it. The inclined pad is placed at the clamping position of the machine tool, and the position of the assembly hole 5 to be processed is clamped to the spindle position in sequence until all the assembly holes are processed after 4 clampings, and the processing efficiency is low. Therefore, at this stage, it is necessary to develop a fixed tooling that does not require repeated pads for the position of the assembly hole to achieve the purpose of rapid processing.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention.
