Description
Technical field
The invention belongs to numerical control special purpose transfer machine technical field, be specifically related to a kind of efficient high-precision grinding cutter and cut the dedicated numerical control double power head modular grinding machine of circular arc camber, mainly clamped one time completes one side while utilizing the different grinding wheel graininesses of double power head to solve high efficient grinding Household knifes to cut thick fine ginding, realize unifying datum, eliminate secondary clamping position error, reduce clamping times, improve working (machining) efficiency and machined surface precision, adopt the process issues such as double power head structure.
Background technology
In recent years, cutter is cut hardware products industry larger development, and export trade volume is increasing year by year, according to statistics in 2012, China is engaged in cutter and cuts the enterprise of production and approximately have 3,000, and the total industrial output value of scissors products year is about more than 100 hundred million yuan, and year foreign exchange earning is over 400,000,000 dollars.Daily hardware products is as kitchen knife, cover cutter, pocket knife, Stupalox and industrial scissors, Scissors, dressmaker's shears etc., because there being quite high hardness just can reach its sharpness and durability, so mostly all will reach by grinding process sharp requirement, physical dimension requirement and the appearance requirement of shear surface and cutting edge.But in the international market, the scissors products of China main or take in, the low value-added product of low side is as main.Up to the present, also there is not the scissors products of the world-famous brands such as picture Germany " one of the Chinese character components ", Japan's " Zhuan Shanlang " board, cause the basic reason of gap to be: product quality.
The operator face of process equipment at present cut to(for) Household knife is one side grinding machine.No matter but current cutter is domestic if being cut special purpose grinder, or import, no matter be conventional hydraulic formula, or the digital control type that new development is got up, they are single-power grinder heads, its production technology nothing more than: the one, on same grinding machine, adopt twice of workbench back and forth working in reciprocating mode move and realize thick fine ginding, be exactly to equal to complete thick fine ginding at same emery wheel like this, its flour milling precision is naturally not high; Another kind is to adopt two lathes, and varigrained emery wheel is installed, and by two subjobs, installs to realize thick fine ginding, although can improve like this roughness of flour milling, due to twice clamping, be difficult to guarantee the dimensional accuracy of flour milling, and working (machining) efficiency is low.Therefore researching and developing the digital-control two-head one side special purpose grinder that a kind of high efficiency, high-accuracy grinding sharpener cut and seem very important, is high-precision, the high efficient grinding equipment that improves scissors products quality.
Summary of the invention
The object of the invention is to overcome existing technology limitation and not enough, the digital-control two-head one side specialized nc machine tool that provides a kind of pair of grinding wheel head structure, clamping is quick, positioning precision the is high grinding cutter that is applicable to plurality of specifications and various materials to cut.
The digital-control two-head one side special purpose grinder that a kind of grinding cutter provided by the invention is cut, frame one side is provided with two spindle assemblies along X-axis, and every cover spindle assemblies front end is installed the emery wheel headstock, and rear end is connected to by motor-driven belt pulley; Frame upper surface is installed the lower slider that can move along X-axis, and the middle slide that can move along Z axis has been installed above lower slider, and the upper surface of middle slide is installed the upper saddle that can move along X-axis, installment work platform on upper saddle, mounting tool post mechanism on workbench.
In above-mentioned, cutter frame mechanism is adjustable, and one end is hinged by hinge and workbench, and the other end is arranged in the chute on workbench by lock pin, and the degree of tightness handle of lock pin is installed; The axle center of two cover spindle assemblies is located in same level, and contour parallel placement, installs respectively Roughing and fine machining emery wheel on two emery wheel headstocks.
The invention has the beneficial effects as follows:
Realize clamped one time and complete the Roughing and fine machining that cutter is cut circular arc camber, improve working (machining) efficiency, solved cutter and cut the problems such as working (machining) efficiency is low, cost is high, Surface Machining precision is low.Effectively shorten process time, reduced labour intensity, reduced labour cost, improved operating efficiency and economic benefit.
Realized clamped one time and completed Roughing and fine machining grinding, reduced the clamping times of workpiece, improved clamping, positioning precision, working (machining) efficiency is high.Reached object high-precision, high efficient grinding.
Having realized smoothly the speed of mainshaft reaches 4000r/min, grinding depth and reaches high rotating speed, high efficiency, the high-precision grinding that 0. 4 ㎜/cutter, positioning precision reach 0.002 ㎜ and 40～50s/ part.

The specific embodiment
Referring to figs. 1 through Fig. 4, the digital-control two-head one side special purpose grinder that a kind of grinding cutter provided by the invention is cut, frame 1 one sides are provided with two spindle assemblies along X-axis, and every cover spindle assemblies 8 front ends are installed the emery wheel headstock 7, and rear end is connected to by motor 10 by the belt pulley 9 of belt drives; Frame 1 upper surface is installed the lower slider 2 that can move along X-axis, lower slider 2 has been installed the middle slide 3 that can move along Z axis above, the upper surface of middle slide 3 is installed the upper saddle 4 that can move along X-axis, installment work platform 5 on upper saddle 4, mounting tool post mechanism 6 on workbench 5, tool rest 18 is installed on cutter frame mechanism 6, tool rest clamping plate 19 are installed on tool rest 18.Wherein, spindle assemblies 8 is arranged on spindle assemblies bearing 12, and motor 10 is arranged on motor support base 11.
During tool grinding, Cutting tool installation manner on tool rest, by the Z axis of slide move the feeding that realizes grinding depth and control; By the X-axis of upper saddle, move and realize the main feeding of grinding and move; By the swing of tool rest and the rotation of rotating shaft, realized the curved surface of tool face and control grinding; By the fast moving of lower slider, realize cutter and work from transfer to the grinding of another emery wheel in the grinding of an emery wheel, reached the thick fine ginding processing technology that realizes cutter on same a machine tool.
Digital control system is selected the 980T digital control system of Guangzhou Guangdong numerical control device Co., Ltd production, realizes the digital control function of lathe.
