Abstract
A gearbox cannon pinion milling spline fixture, belongs to processing technique field; It comprises the chuck seat of milling machine, on the circumference of chuck seat, be fixed with the clamping device that gear part is installed, this clamping device comprises grip block, the middle part of grip block offers clamping hole, in grip block, be provided with the open seam being connected with clamping hole, one end in the corresponding open seam in the side of grip block is provided with bolt hole, is combined with and makes clamping hole realize the bolt that rigidity clamps in bolt hole; Because the inner headed face of clamping hole is that face contacts with gear part outside circle, in process, can realize zero clearance, guarantee machining accuracy, solve existing fixture and had the problem that location is inaccurate, percent defective is high; Grip block is provided with can realize the open seam that rigidity clamps; This gearbox cannon pinion milling spline fixture only needs the hexagon socket head cap screw in elasticity bolt hole in actual processing and loading clamp, and the installation that just can complete workpiece clamps and dismounting, has improved greatly operating efficiency.
Description
Technical field
The utility model relates to technical field of processing equipment, especially a kind of gearbox cannon pinion milling spline fixture.
Background technology
Gearbox is can fix or stepping changes the gear drive of output shaft and power shaft gearratio, can the in the situation that of high rotating speed, high load capacity, rotating speed and the continuous alternation of load, work; Gearbox cannon pinion is the important component part of gearbox, and it comprises hollow axis body, and one end of hollow axis body is provided with gear part, the other end of hollow axis body is provided with spline part, when milling spline part, need the gear part of the hollow axis body of clamping, then milling spline part; And the fixture of traditional gearbox cannon pinion milling spline, conventionally in fixture endoporus, offer the one or more key teeth that are meshed with gear part teeth groove, because gearbox cannon pinion is complex-shaped, the accuracy of gear requires high, adopts in this way, easily there is in the course of the work gap in key tooth and teeth groove, locate inaccurately, the spline part processing is irregular, often with protruding stupefied, percent defective is high, and versatility is poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of for vertical knee-type milling machine, guarantees that spline part keyway reaches the gearbox cannon pinion milling spline fixture of specification requirement and convenient mounting and clamping.
The technical scheme in the invention for solving the technical problem is: a kind of gearbox cannon pinion milling spline fixture, the chuck seat that comprises milling machine, the middle part of chuck seat is provided with the cone bar identical with its hole taper of hollow axis body, on the circumference of chuck seat, be fixed with the clamping device that gear part is installed, this clamping device comprises grip block, the middle part of grip block offers clamping hole, is provided with the open seam being connected with clamping hole in grip block, and one end of this open seam extends to outside grip block; One end in the corresponding open seam in the side of grip block is provided with bolt hole, is combined with and makes clamping hole realize the bolt that rigidity clamps in bolt hole; The other end of grip block is fixed with the assembling block being connected with chuck seat.
This assembling block comprises the fixed block being fixedly installed on grip block, and is welded on the riser on fixed block, the contiguous block Joint on this riser and chuck seat.
The beneficial effects of the utility model are: because inner headed face and the gear part outside circle of clamping hole is that face contacts, in process, can realize zero clearance, guarantee machining accuracy, solve existing fixture and had the problem that location is inaccurate, percent defective is high; Grip block is provided with can realize the open seam that rigidity clamps; This gearbox cannon pinion milling spline fixture only needs the hexagon socket head cap screw in elasticity bolt hole in actual processing and loading clamp, and the installation that just can complete workpiece clamps and dismounting, has improved greatly operating efficiency.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the perspective view of the utility model clamping device.
In figure: 1. grip block, 2. clamping hole, 3. riser, 4. fixed block, 5. bolt hole, 6. open seam, 7. chuck seat, 8. cone bar, 9. contiguous block.
the specific embodiment:
With reference to Figure of description, the utility model is described in further detail.
As shown in Figure 1-2: a kind of gearbox cannon pinion milling spline fixture described in the utility model, comprise the chuck seat 7 being arranged on milling machine, the middle part of chuck seat 7 is provided with the cone bar 8 identical with its hole taper of hollow axis body, on the circumference of chuck seat 7, be connected with the clamping device that gear part is installed, this clamping device comprises that the middle part of grip block 1, grip block 1 offers clamping hole 2, in grip block 1, be provided with the open seam 6 being connected with clamping hole 2, one end of this open seam 6 extends to outside grip block 1; One end in the corresponding open seam 6 in the side of grip block 1 is provided with bolt hole 5, is combined with and makes clamping hole 2 realize the bolt that rigidity clamps in bolt hole 5; This bolt is preferably hexagon socket head cap screw; The other end of grip block 1 is fixed with the assembling block connecting with described chuck seat 7, and this assembling block comprises the fixed block 4 being movably connected on grip block 1, and is welded on the riser 3 on fixed block 4, contiguous block 9 Joints on this riser 3 and chuck seat 7.
During use, by hollow axis body in it bore portion be nested with on the cone bar 8 at chuck seat 7 middle parts, and gear part is placed in described clamping hole 2; Even if the outside circle of gear part part matches with the inner headed face of clamping hole 2, and regulates by the hexagon socket head cap screw in its bolt hole 5 of open seam 6 one sides; Making clamping hole 2 that gear part is reached to rigidity clamps;
Add man-hour, a milling cutter is fixed on the tool mounting of vertical knee-type milling machine top, gearbox cannon pinion is fixed on travelling carriage, and travelling carriage is when moving to left, milling cutter mills out an elongated slot on the spline part of hollow axis body, then the spline part of gearbox cannon pinion is milled out; Because gear part outside circle and the inner headed face of clamping hole are that face contacts, in process, can realize zero clearance, guarantee machining accuracy, solve existing fixture and had the problem that location is inaccurate, percent defective is high.
Except technical characterictic described in description, be those skilled in the art known technology.
