Abstract
The invention discloses a small-caliber circular tube three-way chamfering device which comprises blades and a tool disc. Three tool grooves are formed in the end face of the tool disc in the radial direction, the blades are fixed in the tool grooves, fixing holes extending towards the tool grooves are formed in the outer side face of the tool disc, and blade fixing bolts for fixing the blades are arranged in the fixing holes. The small-caliber circular tube three-way chamfering device has the advantages that the problems that a three-way machining turning tool for machining a small-caliber circular tube is prone to being broken, and continuous and stable machining cannot be carried out are solved, meanwhile, the three-way chamfering device enables the blades to be directly fixed to the tool disc, and therefore the three-way chamfering device can meet the continuous and stable machining requirement. In the small-caliber circular tube three-way chamfering device, an end face tool, an inner chamfering tool and an outer chamfering tool are all standard blades, due to the fact that the blades are directly fixed to the tool disc through the bolts, the strength of each blade is enough, in the using process, no breakage phenomenon exists, the machining requirement can be continuously and stably met except for the situation that cutting edges are normally abraded and the blades need to be ground through shutdown, production cost is lowered, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of equipment for chamfering.
Background technology
The Double end chamfering machine using at present adds man-hour falling inside and outside angle and face work, need to use a kind of standard triangular knife, lathe tool is middle porose equilateral triangle standard insert, wherein end face edge facing to the end face of pipe, exterior angle edge, facing to outside, the interior angle cutter of circular tube end face, be placed in pipe and cutting edge facing to the inner side of circular tube end face, blade is to be fixed on knife rest through middle hole with bolt, and knife rest is fixed on cutterhead again.
While utilizing above-mentioned chamfering device to process the small-bore pipe of a kind of external diameter 13mm, internal diameter 10mm, can be because blade need be contained on knife rest, and in the situation that internal diameter only has 10mm, interior angle knife-edge shape can only be very little, circular hole in the middle of causing is 1mm left and right only apart from cutting edge limit, intensity extreme difference, and slightly situation just fractures, poor in processability, has increased enterprise's processing cost continuously.
Summary of the invention
Technical problem to be solved by this invention is to realize a kind ofly can processing small-bore pipe chamfering, and reliable operation, the three-dimensional chamfering device of good stability.
To achieve these goals, the technical solution used in the present invention is: a kind of small-bore pipe three-dimensional chamfering device, comprise blade, cutterhead, the end face of described cutterhead is radially provided with three cutter grooves, described blade is fixed in cutter groove, described cutterhead lateral surface is provided with the fixing hole extending to cutter groove, is provided with the plough bolt of fixed blade in described fixing hole.
Described blade comprises interior angle cutter, exterior angle cutter and end face cutter.
The described angle settings such as cutter groove.
The invention has the advantages that solved process small-bore pipe three-dimensional processing lathe tool easy fracture, can not continous-stable processing problem, simultaneously, this three-dimensional chamfering device is that blade is directly fixed on cutterhead, and such three-dimensional chamfering device can meet continuously, processing request stably.In an embodiment; end face cutter, interior angle cutter and exterior angle cutter are all standard insert; owing to being directly fixed on cutterhead with bolt; the intensity of every kind of blade is all enough, during use, and the phenomenon not fractureing; except cutting edge normal wear need be shut down grinding blade; can continuously, stably meet processing request, reduce production cost, improve production efficiency.
Accompanying drawing explanation
Below the content of every width accompanying drawing expression in description of the present invention and the mark in figure are briefly described:
Fig. 1 is pipe three-dimensional chamfering device structural representation;
Fig. 2 is cutaway view in Fig. 1;
Mark in above-mentioned figure is: 1, plough bolt; 2, end face cutter; 3, cutterhead; 4, interior angle cutter; 5, lathe tool.
The specific embodiment
This three-dimensional chamfering device is directly blade to be fixed on cutterhead on 3 with bolt, specifically known referring to Fig. 1, the processing end face of cylindrical cutterhead 3 is radially provided with three cutter grooves, the angles such as cutter groove are provided for fixed blade, at cutterhead lateral surface, be provided with the fixing hole extending to cutter groove, and in each fixing hole, be provided with the plough bolt 1 of fixed blade, blade comprises interior angle cutter 4, exterior angle cutter 5 and end face cutter 2, is separately fixed in three cutter grooves.
The intensity of every kind of blade is all enough, during use, and the phenomenon not fractureing; except cutting edge normal wear need be shut down grinding blade, can continuously, stably meet processing request, because the blade using is standard insert; every only needing 30 yuan of left and right, cost is relatively low.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
Claims (3)
