Abstract
The invention relates to a four-hole drilling tool for a casing flange. The drilling tool comprises a base plate and a central spindle. The central spindle is fixedly arranged on the base plate through a screw. The central spindle is a stepped shaft, and the outer wall of the shaft end of the central spindle is provided with a thread. The central spindle is sleeved with a bushing plate. The bushing plate is fixed to the axial position of the central spindle through a shaft shoulder of the central spindle. A press plate is arranged above the bushing plate, and a nut is arranged above the press plate. The nut is in fastened connection with the central spindle through the thread arranged on the outer wall of the shaft end of the central spindle. The drilling tool is simple in structure, reasonable in design, high in stability and capable of effectively solving the problem that the drilling accuracy of the casing flange is low and ensuring the safety in the machining process.
Description
Technical field
The present invention relates to a kind of auxiliary equipment of machining, be specifically related to a kind of casing flange and bore four hole tools.
Background technology
Drilling machine refers to the lathe mainly using drill bit machining hole on workpiece.Usual bit is main motion, and drill bit moves axially as feed motion.Drilling machine structure is simple, and machining accuracy is relatively low, can holes drilled through, blind hole, changes special tool, can expand, spot-facing, reams or carries out the processing such as tapping.In process, workpiece is motionless, allows cutter move, and by center cutter alignment hole center, and makes cutter rotate (main motion).The feature of drilling machine is that workpiece maintains static, and cutter rotates.
The steps necessary of casing flange in process of manufacture when holing to casing flange with drilling machine, existing casing flange drilling tool unreasonable structure, causes in boring procedure, due to casing flange poor stability, causes machining accuracy inadequate.
Summary of the invention
For solving the above-mentioned problems in the prior art, the invention provides a kind of security high, simple and reasonable casing flange bores four hole tools.
Technique effect of the present invention is achieved through the following technical solutions:
A kind of casing flange bores four hole tools, and comprise base plate and mandrel, described mandrel is fixedly installed on base plate by screw, described mandrel is multidiameter, described mandrel axle head outer wall is provided with screw thread, on described mandrel, is arranged with bushing plate, described bushing plate is fixed at mandrel axial location by the mandrel shaft shoulder, above bushing plate, be provided with pressing plate, above described pressing plate, be provided with nut, described nut is fastenedly connected by screw thread that mandrel axle head outer wall is arranged and mandrel.
Wherein, described pressing plate is opening pressing plate.
Wherein, flat key is provided with between described mandrel and described base plate.
Wherein, on described bushing plate, drill bushing is provided with.
Wherein, described drill bushing is 4.
Wherein, described drill bushing is fixed on bushing plate by soket head cap screw.
The invention has the beneficial effects as follows:
Structure of the present invention is simple, and reasonable in design, stability is high, effectively can improve the security that the low problem of casing flange borehole accuracy guarantees process.
Accompanying drawing explanation
Fig. 1 is that a kind of casing flange disclosed by the invention bores four hole tool front views;
Fig. 2 is that a kind of casing flange disclosed by the invention bores four hole tool top views.
Detailed description of the invention
As Fig. 1, shown in 2, a kind of casing flange bores four hole tools, comprise base plate 1 and mandrel 2, described mandrel 2 is fixedly installed on base plate 1 by screw 8, described screw 8 is soket head cap screw, described mandrel 2 is multidiameter, described mandrel 2 axle head outer wall is provided with screw thread, on described mandrel 2, be arranged with bushing plate 7, described bushing plate 7 is fixed at mandrel 2 axial location by mandrel 2 shaft shoulder, above bushing plate 7, be provided with pressing plate 4, above described pressing plate 4, be provided with nut 3, described nut 3 is fastenedly connected by screw thread that mandrel 2 axle head outer wall is arranged and mandrel 2.
Wherein, described pressing plate 4 is opening pressing plate.
Wherein, flat key 9 is provided with between described mandrel 2 and described base plate 1.
Wherein, on described bushing plate 7, drill bushing 6 is provided with.
Wherein, described drill bushing 6 is 4.
Wherein, described drill bushing 6 is fixed on bushing plate 7 by soket head cap screw 5.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
