The processing cost of grooving screws can be reduced.
Description
The utility model relates to the technical field of groove milling process equipment, particularly the device of screw head groove milling.
Traditional screw, screw, its head groove milling processing of bolt are to adopt horizontal milling machine, by anchor clamps part are positioned on the lathe bed by the milling cutter grooving.The major part of anchor clamps is the trisection cartridge clips that adopt screw means, and its manufacturing procedure is totally seven work steps: material loading, and------groove milling---oppositely---is unclamped---discharging---and is blown bits in clamping.These seven work steps of conventional processes are finished by hand by the operator, and production is long non-cutting time, and working (machining) efficiency is low and anchor clamps are made difficulty, product quality is unstable.
The purpose of this utility model is the weak point that overcomes conventional art, and the rotary screw slot-cutting machine of a kind of production efficiency height, good, simple to operate, the stable processing quality of processing interchangeability is provided.
The purpose of this utility model is achieved by the following technical solution: a kind of rotary screw slot-cutting machine, include frame, be loaded on the milling cutter on the frame, cross feed device and longitudinal feeding device, pulley gear and the screw workpiece clamping positioning mechanism of control milling cutter motion, be furnished with a great wheel in opposite directions with milling cutter on the frame, a plurality of clamping positioning mechanisms are fixed in by five equilibrium on the circumference of great wheel, and each screw workpiece termination is loaded on the locating surface of clamping positioning mechanism outwardly and order contacts with milling cutter with the rotation of great wheel; Be fixed with the floating platen mechanism that acts on mutually with clamping positioning mechanism at the milling cutter and the side of great wheel, clamping positioning mechanism rotates into floating platen mechanism with great wheel, compress effect that pin is subjected to spring bearer plate with the screw Work-sheet pressing on the clamping positioning mechanism, make the screw workpiece with compacted being positioned on the clamping positioning mechanism before milling cutter contacts.Further, clamping positioning mechanism by contiguous block, compress pin, thin-walled spring chuck, caging bolt and constitute, contiguous block integral body is anchored on the great wheel, and the thin-walled spring chuck is loaded in the hole of locating surface, compresses the cooperation that contacts with the thin-walled spring chuck of hole that pin passes sidewall.And floating platen mechanism is made of fixed head, spring bearer plate, spring, pin, and fixed head is anchored on the frame and is erected in great wheel and the side of milling cutter, and spring bearer plate is arranged in parallel by pin and fixed head, and between spring bearer plate and the fixed head spring is housed.
Below in conjunction with drawings and Examples structure of the present utility model and advantage are described further.

Fig. 2 is the schematic perspective view of Fig. 1 upper body;
Fig. 3 is the solid partition figure of clamping positioning mechanism;
Fig. 4 is the three-dimensional cutaway view of clamping positioning mechanism;
Fig. 5 is the stereogram of floating platen mechanism;
Fig. 6 is the solid partition figure of floating platen mechanism.
Referring to Fig. 1-Fig. 6, present embodiment mainly is made of frame 6, the milling cutter 3 that is loaded on frame 6 tops, cross feed device 1, longitudinal feeding device 4, pulley gear 2, great wheel 5, clamping positioning mechanism and floating platen mechanism etc.Great wheel 5 is arranged in opposite directions with milling cutter 3, employing stepless speed regulation, and rotating speed is 1.6-6r/min, a plurality of clamping positioning mechanisms, and are evenly distributed by five equilibrium on the circumference of great wheel 5 by bolted.Clamping positioning mechanism by contiguous block 11, compress pin 12, thin-walled spring chuck 8, caging bolt 13 and constitute (as shown in Figure 3, Figure 4), the just top of clamping positioning mechanism is locating surface, have hole 14 on the locating surface; thin-walled spring chuck 8 is loaded in the hole 14; lateral surface of locating surface also has a hole 15; hole 15 connects with hole 14; compress that pin 12 is loaded in the hole 15 and the cooperation that contacts with thin-walled spring chuck 8 in the hole 14; when compressing pin 12 pressurizeds; thin-walled spring chuck 8 is compressed the effect of pin 12 and strain, and diameter diminishes.Floating platen mechanism constitutes (as Fig. 5, shown in Figure 6) by fixed head 16, spring bearer plate 17, spring 18, pin 19, fixed head 16 is anchored on the frame 6 and is erected in milling cutter 3 and the side of great wheel 5, spring bearer plate 17 is arranged in parallel with fixed head 16, be installed with many pins 19 between them and sell spring 18 all is housed on 19, the distribution of spring 18 is heterogeneous, more near the machining area of milling cutter 3, the distribute spacing of spring 18 is more little, intensive more on spring bearer plate 17.
The course of work: the Working position of at first adjusting milling cutter 3 by cross feed device 1 and longitudinal feeding device 4, meanwhile great wheel 5 is driven by stepless electrical machinery and is rotated counterclockwise, screw workpiece 20 to be processed is put into the thin-walled spring chuck 8 of clamping positioning mechanism by operating personnel, and screw workpiece 20 is because deadweight can abut against on thin-walled spring chuck 8 locating surfaces and together rotate with great wheel 5.When rotating to when compressing the zone, when promptly entering floating platen mechanism, the pin 12 that compresses on the clamping positioning mechanism is subjected to the pressure of spring bearer plate 17 and spring 18 and compresses thin-walled spring chuck 8, and make it strain, thereby screw workpiece 20 is clamped, because spring 18 skewness on the spring bearer plate 17 are more little near milling cutter 3 its spacings more, clamping force maximum when like this, screw workpiece 20 is subjected to milling cutter 3 cuttings.After screw workpiece 20 is cut, be rotated further with great wheel 5, compress pin 12 and break away from floating platen mechanism, spring bearer plate 17 is removed compressing the pressure of pin 12; breach of thin-walled spring chuck 8 opens again, and this moment, screw workpiece 20 just went to below with great wheel 5, and screw workpiece 20 is upside down; and, fall into discharge port because of deadweight breaks away from thin-walled spring chuck 8.In addition, 16 the switch backing pins 9 corresponding with thin-walled spring chuck 8 evenly are installed on the great wheel 5, frame 6 is provided with and the travel switch 10 of switch backing pin 9 effects and the blow gun 21 that controlled by travel switch 10, when thin-walled spring chuck 8 rotates to the below, its corresponding switch backing pin 9 touches travel switch 10,21 pairs of thin-walled spring chucks 8 of blow gun blow material, blow bits, guarantee that screw workpiece 20 breaks away from anchor clamps fully on the one hand, blow away on the other hand and consider to be worth doing the residual spare time that adds, to guarantee the accurate positioning of piece installing next time.The milling cutter of present embodiment has three grades of rotating speed: 500r/min, 700r/min, 900r/min for choosing the range of work: cutting width 0.5-3mm, cutting depth 0-3mm, grooving length 3-8mm.Per hour can process screw workpiece 1500-4000 spare.
In sum, the utlity model has obvious advantage:
1, production efficiency height, tooling step reduces to one by seven, all the other workers behind the material loading Step is finished by device, and production efficiency improves nearly ten times than traditional operation;
2, product quality better, owing to work continuously, the automaticity height can be because of not artificially Misoperation and affect crudy;
3, versatility, interchangeability are good, and only needing to change spring chuck can process different products, and clamping force is adjustable, adapts to different types of material, thereby obtains best clamping effect.
