Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of vertical machining centre flexible jig for processing the uniform screw of bearing block end face as illustrated in fig. 1 and 2, bag Including positioner and clamping device, described positioner includes base 1, the alignment pin 19 that is fixed on base 1 and to determining device; Described alignment pin 19 includes upper end big footpath cylinder and lower end path cylinder, is provided with interior cylindrical hole, alignment pin 19 in described base 1 Path cylinder put in the cylindrical hole of base 1, the cylinder of path cylinder contacts with the wall of interior cylindrical hole, thus realizes The location of alignment pin 19;Described alignment pin 19 is provided with centre bore;It is cased with workpiece 12, the end on the face of cylinder, big footpath of described alignment pin 19 The big footpath cylindrical wall of seat 1 end face and alignment pin 19 positions in the face of workpiece 12, limits five degree of freedom of workpiece 12, workpiece 12 It is provided with radially counterbore.
Described to determine device include riser 4, handle 5, to rationed marketing 7 and positioning sleeve 9, on described base 1 Parallel Symmetric arrange Circular arc rectangular channel, described riser 4 is had to be fixed on the circular arc rectangular channel of base 1;It is provided with cushion block between described riser 4 and base 1 2, riser 4 center is provided with hole;Described positioning sleeve 9 one end is vertically embedded in the hole of riser 4, and the other end is arranged with open slot, in Between end face be fixed on riser 4;Described rationed marketing 7 is run through positioning sleeve 9, rationed marketing 7 is provided with location near one end of workpiece 12 Cylinder, described positioning cylinder is suitable with the radial direction counterbore of workpiece 12, and the other end of rationed marketing 7 is fixed with handle 5, described right Extending vertically through in rationed marketing 7 and be provided with pin II 8, the length of pin II 8 is more than the internal diameter of positioning sleeve 9;Described limit determining device Workpiece 12, around a rotary freedom of alignment pin 19, limits the six-freedom degree of workpiece 12 altogether, meets the uniform spiral shell of workpiece 12 The positioning requirements of hole machined.
Described clamping device includes opening pressing plate 13, studs 14 and binding nut 15, the one of described studs 14 End passes perpendicularly through alignment pin 19 and is fixed on base 1;Described opening pressing plate 13 is placed on work through the other end of studs 14 On part 12, described binding nut 15 is tightened against the other end of studs 14, and the external diameter of binding nut 15 is more than opening pressing plate 13 A/F;Using spanner to realize binding nut 15 to the clamping of workpiece 12 and to unclamp, the hatch frame of opening pressing plate 13 is big Shorten greatly the impulse stroke that binding nut 15 clamps and unclamps, it is achieved the quick despatch of workpiece 12.
In order to make the positioning cylinder to rationed marketing 7 one end can quickly embed in the radial direction counterbore of workpiece 12, meanwhile, in order to make Rationed marketing 7 can be realized faster mobile, described to determine device also include spring 11, described spring 11 be enclosed within rationed marketing 7 also Between riser 4 and positioning cylinder.
In order to make opening pressing plate 13 realize more rapid and position accurately, described clamping device also includes that at least two is spacing Pin 16, one end of described spacer pin 16 is perpendicularly fixed on base 1, and spacer pin 16 is respectively positioned on the opening side of opening pressing plate 13 also Contact with two parts up and down of opening pressing plate 13.
Dismantling and make more firm being fixed on base 1 of alignment pin 19 for convenience, described positioner also includes fixing Nut 18, alignment pin 19 is anchored on base 1 by threaded adapter by fixing nut 18 with studs 14.
In order to ensure assembly precision, the middle end face of described positioning sleeve 9 is fixed on riser 4 by soket head cap screw II 10 On;Described handle 5 passes through pin I 6 fixed cover at the other end to rationed marketing 7;Described riser 4 is fixed on by soket head cap screw I 3 On the circular arc rectangular channel of base 1.
The plane distribution of working position processing screw hole 17, positioner and the clamping device of workpiece 12 is as shown in Figure 1.When When the size of a range of workpiece 12 changes, it is only necessary to change alignment pin 19 and to rationed marketing 7 and different high by changing The cushion block 2 of degree regulates the height to rationed marketing 7, is regulated fixed by the cooperation of four soket head cap screws I 3 and circular arc rectangular channel The position of pin 7 horizontal direction, pin 7 position to be positioned is tightened soket head cap screw I 3 after mixing up and is fixed on base 1 by riser 4, i.e. Locating and machining and the clamping of the uniform screw of series axis bearing can be realized.This fixture is by base 1 with through base 1 two ends ear mount 20 Studs and fixing nut be fixed on three shaft vertical machining center workbench.
Before processing, first base 1 is positioned on vertical machining centre workbench, T-shaped spiral shell is loaded onto in studs one end Mother also loads in the T-slot on workbench, and other end passes the ear mount 20 at base 1 two ends and by fixing nut by base 1 Pretension, on workbench, carries out centering with the leading flank of base 1 to fixture, uses spanner dextrorotation to tighten fixing nut fixture is solid Determine on the table.Again the lower end path cylinder of alignment pin 19 is put in the cylindrical hole of base 1, by the one of studs 14 End passes perpendicularly through alignment pin 19 and is fixed on base 1, and fixing nut 18 passes the other end of studs 14 by tight for alignment pin 19 It is fixed on base 1;Carry out X, Y-axis center to cutter with the big footpath cylinder wall of alignment pin 19, carry out Z seat with the end face of alignment pin 19 Parameter, to cutter, determines the benchmark zero point that tool sharpening moves.
Then, with hands elder generation handle 5, make rationed marketing 7 is moved to the left (away from the direction of workpiece 12) segment distance, then rotate Handle 5 makes pin II8 be stuck on the end face of positioning sleeve 9 so that is blocked rationed marketing 7 by pin II8, will not be moved to the left again, this Time spring 11 be in compressive state, then workpiece 12 is put on the big footpath cylinder of alignment pin 19, and makes the radial direction counterbore of workpiece 12 Approximate alignment is to rationed marketing 7;Rotary handle 5 makes pin II8 be at positioning sleeve 9 open slot again, due to the bounce of spring 11, pin Nail II8 enters in positioning sleeve 9 open slot, so rationed marketing 7 is moved right pressure on work piece 12, make with hands somewhat rotational workpieces 12 Radially counterbore alignment is to rationed marketing 7, because the elastic force effect of spring 11 makes to enter the positioning cylinder in rationed marketing 7 immediately radially counterbore In, limit the six-freedom degree of workpiece 12 altogether, complete being properly positioned of workpiece 12.By opening pressing plate 13 opening through double end spiral shell Post 14 is placed on work piece 12, and pushes the direction of spacer pin 16 to, and two spacer pins 16 and studs 14 i.e. determine opening The tram of pressing plate 13, uses the spanner binding nut 15 that turns clockwise to compress opening pressing plate 13, thus realizes workpiece 12 Quick-clamped, and then holding shaft bearing will not loosen along with the course of processing, and then guarantee its invariant position, thus ensure to add The machining accuracy of work screw 17.
Finally, machining center runs the processor of the uniform screw of bearing block, is automatically performed drill centers, bores thread Pilot hole Process with tapping etc..After completion of processing, unclamp opening pressing plate 13 with spanner rotating clamp counterclockwise jack panel 15, and by opening pressure The hatch frame of plate 13 quickly takes off opening pressing plate 13;Pull handle 5 again to make rationed marketing 7 is moved to the left a segment distance, then rotate Handle 5 makes pin II8 be stuck on the end face of positioning sleeve 9 so that is blocked rationed marketing 7 by pin II8, will not be moved to the left again, from And realize quickly laying down of workpiece 12.
