Detailed description of the invention
The present invention is described in further detail for the engine support bottom hole fixture adopting structure of the present invention below in conjunction with a kind of and accompanying drawing.
During concrete enforcement: as shown in Fig. 2 ~ Fig. 4, a kind of engine support bottom hole fixture, comprise overall rectangular base plate 1, wherein, described base plate 1 is provided with in the width direction two the first detent mechanisms 2 positioned for the side for the treatment of machining support, is also provided with one and carries out the second spacing detent mechanism 3 for treating machining support along base plate 1 width; Described base plate 1 also has three respectively with the corresponding resigning hole 11 arranged of installing hole of support to be processed behind location, the diameter of described resigning hole 11 is more than or equal to the installing hole diameter of support to be processed; Described base plate 1 is also provided with two for compressing the hold-down mechanism 4 of support to be processed along base plate 1 thickness direction towards base plate 1.
During use, by the bottom surface of support to be processed towards base plate, support to be processed is being close to the first detent mechanism and the second detent mechanism, the side utilizing the first detent mechanism to treat machining support positions, utilizing the second detent mechanism to treat machining support in baseplate width direction carries out spacing, like this, by three anchor points, support to be processed is positioned on base plate; Then utilize hold-down mechanism to be fixed on base plate by support to be processed, complete the clamping of support to be processed.Finally, base plate is together overturn 180 ° together with support to be processed, support to be processed is lain in a horizontal plane on lathe down, drill bit is passed processing that resigning hole completes the installing hole treating machining support.Adopt this fixture, can be located by support to be processed fast, structure is simple, is easy to make.Hole after support upset to be processed from bottom, vertical with work surface when can ensure that drill bit starts to hole, place drill bit deflection, be conducive to the quality improving boring.
During concrete enforcement, described first detent mechanism 2 comprises the first positioning seat and level and runs through the first adjustment screw that positioning seat arranges, and described first adjustment screw is arranged along the length direction of base plate 1.Comprise described second detent mechanism 3 second positioning seat and level run through the second adjustment screw that positioning seat is arranged, and described second adjustment screw is arranged along the width of base plate 1.During use, the face that the end of the first adjustment screw and the second adjustment screw all can be located as required adjusts, and ensures the precision of fixture.
Wherein, also comprise horizontally disposed base 5, described base 5 is vertically provided with two just right gripper shoes 51; Described base plate 1 is between two described gripper shoes 51, and described base plate 1 both sides are in the width direction hinged in corresponding gripper shoe 51; Described base plate 1 is positioned at the center of described base plate 1 thickness direction around the shaft center line that described gripper shoe 51 rotates, and near the side of described base plate 1 length direction; Described base 5 also arranges at least two columns 52, described column 52 lays respectively at the both sides of the shaft center line of described base plate 1, distance between the axial line of described column 52 and the shaft center line of base plate 1 is greater than the minimum range of shaft center line to described base plate 1 both sides along its length of base plate 1, is less than the ultimate range of shaft center line to described base plate 1 both sides along its length of base plate 1; The height of described pillar 52 equal described base plate 1 parallel with base 5 time distance therebetween, and be greater than the maximum clamping height after support clamping to be processed.
During use, can by base plate be overturn around shaft center line, meanwhile, column can remain level after the upset of guarantee base plate, makes this more convenient to operate, saves the operating time, improve working (machining) efficiency.
Wherein, described hold-down mechanism 4 comprises the pillar 41 be vertically set on base plate 1, is hinged on the pressing plate 42 at pillar 41 top, and described pressing plate 42 has the bar hole arranged along its length on the side of the clamping position of support to be processed; Also comprise the bolt of the bar hole run through successively on base plate 1 and pressing plate 42.Like this, make the structure of hold-down mechanism simple, be easy to make.
Wherein, be all set with reaming shoe 12 in described resigning hole 11, the diameter of bore of described reaming shoe 12 equals the installing hole diameter of support to be processed.Like this, when the base plate treating machining support is holed, reaming shoe has guide effect to drill bit, prevents installing hole drill inclined, is conducive to improving machining accuracy.
A method for engine support base plate boring, comprises the steps:
The engine support bottom hole fixture of a, acquisition said structure;
B, the bottom surface of support to be processed is placed on base plate towards described base plate, and make the orientation of installing hole to be processed on support to be processed consistent with the orientation of the resigning hole on base plate, then support to be processed is fitted with the first detent mechanism and the second detent mechanism simultaneously, finally utilize hold-down mechanism to be fixed on base plate by support to be processed;
