Abstract
The utility model relates to a positioning fixture for gear grinding, comprising a base, a supporting body and a workpiece positioning base which are connected integrally. The workpiece positioning base is supported on the base through the supporting body, a bolt through groove is arranged at the edge of the workpiece positioning base, a positioning boss is arranged on the workpiece positioning base, and the positioning boss can be in clearance fit with a center hole of a to-be-grinded gear. A planet gear in a gear transmission mechanism of a wind driven generator can be fast and conveniently clamped and positioned on a gear grinding machine through the positioning fixture, thereby reducing grinding and processing time of the planet gear, and increasing production efficiency.
Description
Technical field
The utility model relates to the frock clamp in the field of machining, especially for the planetary gear in the gear drive of clamping wind-driven generator, planetary tooth is carried out the quick positioning fixture of gear grinding of grinding.
Background technology
Have planetary gear in the gear drive of wind-driven generator, a roll flute operation is arranged in this planetary processing technology, because the roll flute operation belongs to the finishing step of gear, so the clamping location of gear on gear grinding machines just seems extremely important.At present, the positioning fixture that uses in planetary roll flute processing to this is made up of the base that combines as a whole, supporter and workpiece positioning seat, the workpiece positioning seat, offers four bolts at workpiece positioning seat edge and crosses groove (as shown in Figure 4) on base by support body supports.For the ease of this planetary gear clamping, be processed with four screwed holes at this planetary end face, it is corresponding that the position of four screwed holes and four bolts that the workpiece positioning seat edge of positioning fixture offers are crossed groove, and positioning fixture goes forward to be fixed on earlier on the workbench of gear grinding machines at gear grinding machines at the planetary gear clamping.
During the clamping planetary gear, the end face that planetary gear is provided with screwed hole is placed on the workpiece positioning seat of positioning fixture down, and the last bolt that spins makes planetary gear be fixed on (this moment, bolt need not screw) on the workpiece positioning seat, because the upper surface of workpiece positioning seat is the plane, so planetary gear is just located in vertical direction, and fail in the horizontal direction to locate, so just must determine planetary gear position in the horizontal direction with the method for planetary centre bore being played table, fastening bolt is again finished the clamping location of planetary gear on gear grinding machines afterwards.Because planetary gear is heavier, it is not too easy on positioning fixture it to be moved, and shows the method for centering planetary gear position extremely to waste time and energy so adopt to beat, and has increased the man-hour of planetary gear grinding, so reduced production efficiency.
The utility model content
The purpose of this utility model provides the quick positioning fixture of a kind of gear grinding, can quickly and easily the planetary gear clamping be positioned on the gear grinding machines by this positioning fixture.
The quick positioning fixture of gear grinding described in the utility model, form by the base that combines as a whole, supporter and workpiece positioning seat, the workpiece positioning seat by support body supports on base, offer bolt at workpiece positioning seat edge and cross groove, the workpiece positioning seat is provided with positioning boss, positioning boss can with the centre bore matched in clearance of intending grinding worm.
Positioning boss is by being bolted on the workpiece positioning seat, on positioning boss and workpiece positioning seat, join and be drilled with two pin-and-holes, be provided with alignment pin in the pin-and-hole with its interference fit, thereby make positioning boss fixing reliably on the workpiece positioning seat, can not relatively move between positioning boss and the workpiece positioning seat because of the external force effect produces.
At the planetary gear clamping before on the gear grinding machines, should earlier positioning fixture be fixed on the workbench of gear grinding machines, and, positioning fixture should make in the position on the gear grinding machines positioning boss axis just in time with the planetary dead in line of planetary gear after finishing the location on the gear grinding machines.
During clamping, directly planetary gear is placed on the workpiece positioning seat of positioning fixture, and make planetary gear pass through positioning boss matched in clearance on its centre bore and the workpiece positioning seat, and with bolt planetary gear is fastened on the positioning fixture again, promptly finish the clamping location of planetary gear on gear grinding machines.
The utility model is because the workpiece positioning seat of positioning fixture is provided with the positioning boss that cooperates with the center planetary gear interporal lacuna, like this, the location of planetary gear on positioning fixture is to realize by planetary end face and centre bore, this just makes planetary gear can be determined quickly and easily in vertical direction on the positioning fixture and the position on the horizontal direction, so can quickly and easily the planetary gear clamping be positioned on the gear grinding machines by this positioning fixture, reduce the man-hour of planetary gear grinding, thereby improved production efficiency.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 looks schematic diagram for the master of the quick positioning fixture of gear grinding described in the utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is positioned at view on this positioning fixture for the planetary gear clamping;
Fig. 4 is positioned at the view that has now on the positioning fixture for the planetary gear clamping.
The specific embodiment
As depicted in figs. 1 and 2, the quick positioning fixture of this gear grinding is by the base 8 that combines as a whole, supporter 1 and workpiece positioning seat 2 are formed, workpiece positioning seat 2 is supported on the base 8 by supporter 1, offer four bolts at workpiece positioning seat 2 edges and cross groove 6, workpiece positioning seat 2 is provided with positioning boss 3, positioning boss 3 is fixed on the workpiece positioning seat 2 by bolt 4, on positioning boss 3 and workpiece positioning seat 2, join and be drilled with two pin-and-holes 7, be provided with the alignment pin 5 with its interference fit in the pin-and-hole 7, positioning boss 3 can with centre bore 11 matched in clearance of intending grinding worm 9.
As shown in Figure 3, during clamping, planetary gear 9 is placed on the workpiece positioning seat 2 of positioning fixture, and make planetary gear 9 by positioning boss 3 matched in clearance on its centre bore 11 and the workpiece positioning seat 2, with bolt 10 planetary gear 9 is fastened on the positioning fixture again, promptly finishes the clamping location of planetary gear 9 on gear grinding machines.
