Embodiment Construction

[0015] Such as figure 1 As shown, the drill jig includes a bracket body and a drill chuck body. The bracket body is composed of a bracket 14, a conical shaft 26, and a driving gear 23. In the bearing seat hole, the driving gear 23 is fixed on the conical shaft 26 through the spring inner card 21 and the B flat key 22, and a group of rotating shaft mounting holes 29 are equally distributed around the center of the bracket on the bracket 14, and the above components are assembled into a bracket body; The drill chuck body described above is composed of drill chuck shaft 10, pinion 7, and drill body 17. The second bearing 3, the spacer sleeve 4 and the centripetal thrust bearing 5 are installed in the middle of the drill chuck shaft 10 through the spring retaining ring 6 in sequence. The small end of the drill chuck shaft 10 is installed with the pinion 7 through the spring inner ring 9 and the A flat key 8, the drill chuck shaft 10 is inserted into the bearing seat hole of the dr...

Abstract

The invention discloses a multi-functional group drilling jig. A conical shaft (26) is fixed in the bearing seat hole of a bracket (14), a drive gear (23) is fixed on the conical shaft (26), and an equal portion is distributed on the bracket (14). Set the shaft mounting holes (29), install the second bearing (3), spacer sleeve (4) and centripetal thrust bearing (5) on the middle part of the drill chuck shaft (10), install the drill chuck shaft (10) at the small end The pinion (7), the drill chuck shaft (10) is inserted into the bearing seat hole of the drill body (17) and fixed, the driven gear (12) in the inner cavity of the drill body (17) meshes with the pinion (7), and the U The shaped cover plate (11) is assembled into a drill clip body; a plurality of drill clip bodies are mounted in series on the support body to form a multifunctional group drill fixture. The drilling jig of the present invention completes equidistant or unequal multi-hole parallel drilling at the same station, which reduces the time for changing workpieces and tools, reduces labor intensity, and reduces the cost of making drilling molds required for multi-hole processing.

Description

technical field [0001] The invention relates to a drilling jig used with a drilling machine, in particular to a multifunctional group drilling jig. Background technique [0002] Drilling machine is the main drilling equipment in mechanical processing. It has vertical, rocker, desktop and other models, and drilling fixture is the main accessory for various drilling machines to hold tools for hole processing. The standard-shaped drilling jig can only hold one drill bit for drilling at a time. For a large number of equidistant or unequal porous parts, its drilling efficiency is obviously insufficient. Contents of the invention [0003] The object of the present invention is to provide a multi-functional group drilling jig, which can not only perform equidistant or unequal multi-hole simultaneous drilling, but also multi-hole simultaneous expansion, countersinking, and joint reaming at the same station. The processing project has a novel structure, unique principle, convenien...
