Problems solved by technology

[0002] We know that when drilling a center hole on an ordinary drilling machine, the depth is usually driven by the tailstock sleeve of the manual operation machine tool to drill the center hole to the part. This method cannot effectively guarantee the accuracy of the hole depth and size, resulting in poor positioning references.

Embodiment Construction

[0013] From figure 1 , figure 2 It can be seen that a drilling center hole depth control device installs and fixes a support sleeve 2 on the taper shank sleeve 15 of the drilling rig, and compresses the screw holes on the support sleeve 2 with screws 43 . Said bracing sleeve 2 tops install dial indicator 1 by fixed rod, and said dial indicator 1 table rod inserts in the hole of fixed rod 3 tops, presses fixed table rod by side screw hole with screw 41. The lower part of the fixed rod 3 is welded on the support sleeve 2. The specific composition and structure of the dial gauge 1 belongs to the prior art. The support sleeve 2 is fixedly connected with a guide sleeve 7 through the connecting plate 5 in the horizontal direction, the left end of the connecting plate 5 is welded with the support sleeve 2, and the right end is welded with the guide sleeve 10. An axially movable guide rod 10 is installed in the guide sleeve 7, the front end of the guide rod 10 is in contact with t...

Abstract

The invention relates to a device for controlling the depth of a drilled center hole. A supporting sleeve is arranged and fixed on a taper shank sleeve of a drilling machine. The upper part of the supporting sleeve is provided with a dial indicator through a fixing rod. A guide sleeve is fixed in the horizontal direction of the supporting sleeve through a connection plate. A guide rod capable of axially moving is arranged in the guide sleeve. The front end of the guide rod is contacted with the end face of a part. The rear part of the guide rod is connected with a contact pad. The contact pad is contacted with an indicator head of the dial indicator. In the feeding process of drilling, the guide rod and the contact pad move backwards to contact the indicator head of the dial indicator, so that the depth of the drilled hole is controlled by observing reading on the dial indicator. The device for controlling the depth of the drilled center hole has a reasonable structure, is convenient to operate and use and has high size control precision.

Description

technical field [0001] The invention relates to a drilling depth control device, in particular to a drilling center hole depth control device. Background technique [0002] We know that when drilling a center hole on an ordinary drilling machine, the depth is usually driven by the tailstock sleeve of the manual operation machine tool to drill the center hole to the part. This method cannot effectively guarantee the depth and dimensional accuracy of the hole, resulting in poor positioning references. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a drilling center hole depth control device with reasonable structure, convenient operation and use, and high dimensional control precision. [0004] The technical solution adopted by the present invention to solve the above technical problems is: a drilling center hole depth control device, which is charact...
