Embodiment Construction

[0010] Referring to the accompanying drawings, the half-shaft disc drilling bolt hole fixture includes a drilling platform, a drilling template positioning clamping plate 3 and a fastening bolt 4. The drilling platform includes left and right columns, left and right base surfaces, left The base surface 20 is fixedly arranged on the upper part of the left column 10, and the right base surface 2 is fixedly arranged on the upper part of the right column 1. The matching positioning hole 30 at the top has a positioning hole 31 for drilling bolt holes beside the positioning hole, and the positioning clamping plate of the drilling template is connected with the left and right base surfaces respectively by fastening bolts.

[0011] There are four positioning holes for drilling the bolt holes, and four drills can process four bolt holes at a time on the disc part of the semi-axis disk through the four positioning holes.

[0012] During use, the top is used for positioning, the disc par...

Abstract

The invention discloses a jig for bolt hole drilling of a semi-shaft disk. The jig comprises a hole drilling platform, a drill jig positioning and clamping plate and fastening bolts. The hole drilling platform comprises a left stand column, a right stand column, a left cardinal plane and a right cardinal plane. The left cardinal plane is fixedly arranged on the upper portion of the left stand column, the right cardinal plane is fixedly arranged on the upper portion of the right stand column, and the left cardinal plane and the right cardinal plane are located on the same horizontal plane. The drill jig positioning and clamping plate is provided with a positioning hole matched with the top of the semi-shaft disk, a positioning hole of a bolt drilling hole is formed beside the positioning hole, and the drill jig positioning and clamping plate is connected with the left cardinal plane and the right cardinal plane through the fastening bolts respectively. According to the jig for bolt hole drilling of the semi-shaft disk, the positioning performance of machining of a semi-shaft disk driller is good, the semi-shaft disk is clamped tightly, stably and firmly, the four bolt holes can be machined and formed at a time, and production efficiency is improved.

Description

technical field [0001] The invention belongs to drilling tooling, in particular to a jig for drilling bolt holes with a half-shaft disk. Background technique [0002] In the prior art, for the half-shaft disk, four bolt holes need to be drilled in the disk part. Because the half-shaft disk is generally circular, its clamping and fixing is quite difficult, and general machine tool fixtures cannot meet the processing needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a jig for drilling bolt holes of the half-shaft disc, which ensures good positioning performance of the half-shaft disc drilling operation, realizes stable and reliable clamping of the half-shaft disc, and can also process and shape four bolt holes at one time ,Increase productivity. [0004] In order to solve the above-mentioned technical problems, the present invention provides a jig for drilling bolt holes on a half-shaft disk, which inclu...
