Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the embodiment of the utility model part, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those skilled in the art obtain under the prerequisite of not making creative work, all belongs to protection domain of the present utility model.
Embodiment 1
See Fig. 1 and Fig. 2, a kind of crank-pin bores oilhole frock, and this frock forms primarily of workbench 1, center oil drill 2, inclined hole drill bit 3, locating hole drill bit 4, inclined hole chmfer bit 5, feeding device 6, clamping device 7 and drive unit.
Clamping device 7 is fixed on the top of workbench 1, and clamping device 7 adopts cylindrical and is provided with cross through hole 8, and the diameter of the bigger about crank-pin of the diameter of through hole 8, the length of through hole 8 is the half of crank-pin length.
Drive unit is installed on the rear end of clamping device 7, and drive unit comprises cylinder 9 and actuating arm 10, and the axis of actuating arm 10 is consistent with through hole 8 axis.Actuating arm 10 is driven to move to through hole end by cylinder 9.The side, front end of actuating arm 10 is provided with railing 11, in order to limit crank-pin to railing 11 1 lateral movement.
Feeding device 6 is for being arranged at the inclined-plane above the workbench between clamping device 7 and drive unit, in order to carry crank-pin to be processed one by one, the workbench 1 of railing 11 offside is fixed in feeding device 6 lower end, and railing 11, actuating arm 10 jointly limit crank-pin with feeding device 6 lower end and move left and right.
Center oil drill 2 is vertically installed on directly over clamping device 7 front end, in order to carry out bore operation to the centre bore of crank-pin straight down.
Locating hole drill bit 4 level is installed on the workbench 1 of the front end of clamping device 7, and locating hole drill bit direction is consistent with through-bore axis direction, for carrying out the operation of brill locating hole from axis direction to crank-pin.
