Drilling jig used for machining of workpiece having special structure

Abstract

The invention relates to a drilling jig used for the machining of a workpiece having a special structure. The drilling jig comprises a drilling jig body, a fastening device and a rotary tool, wherein a workpiece is mounted on the drilling jig body through the fastening device; the drilling jig body is fixed on the rotary tool; the drilling jig body comprises a drilling jig base plate, drilling jig side plates, a bottom drilling sleeve and a side drilling sleeve; the rotary tool comprises a support frame, an end plate, a rotary shaft and a speed reducer; the drilling jig further comprises a fixing support plate; the fixing support plate is fixedly connected onto a machine tool; the rotary shaft of the rotary tool extends out of the fixing support plate to be connected with the speed reducer; and pin holes are formed in the fixing support plate and the end plate separately in a matched manner. According to the drilling jig used for the machining of the workpiece having the special structure, the drilling machining of the bottom and the side surfaces of the workpiece having the special structure is realized, the hole machining function of numerical control equipment can be realized through a drilling machine, the hole machining of different surfaces is realized, the efficiency is high, and the machining cost is low.

Description

technical field [0001] The invention relates to a drilling jig, in particular to a drilling jig used for processing workpieces with special structures. Background technique [0002] As known, a jig is a machine tool fixture used to guide a tool to drill holes (see drilling) or ream holes (see reaming) on ​​a workpiece. The structural feature of the drilling template is that in addition to the positioning and clamping device of the workpiece, there are also drill sleeves and drilling templates set according to the position distribution of the processed holes to determine the position of the tool and prevent the tool from tilting during processing. , so as to ensure the position accuracy of the processed hole. [0003] A workpiece with a special structure has holes on its bottom and sides. The traditional drilling method is to use a CNC gantry boring and milling machine to process. After drilling the holes on the bottom, it is necessary to install a side milling machine when ...

Problems solved by technology

[0003] A workpiece with a special structure has holes on its bottom and sides. The traditional drilling method is to use a CNC gantry boring and milling machine to process. After drilling the holes on the bottom, it is necessary to install a side milling machine when processing the holes on the side. Head, low efficiency, high processing cost

[0004] Existing drilling jigs with a rotary function that can realize drilling on multiple surfaces usually only solve the processing of holes on the surrounding surfaces of the rotary, or only perform upper and lower drilling, and cannot be applied to the above-mentioned workpieces with special structures In the drilling, the hole processing on the bottom and side of the workpiece cannot be fully completed
