Abstract
The utility model discloses a shaft tooth hobbing fixture driven by a hydraulic tensioning end face. The shaft tooth hobbing fixture comprises a fixture base assembly, a pull rod assembly, a pull claw and a pop-rivet. A locating plane, a locating hole and a pull rod are arranged on the fixture base assembly to constitute a mounting hole, the pop-rivet is connected with the pull rod assembly through the pull claw, and a locating shaft shoulder section matched with the locating hole, a shaft neck section at the center of a locating shaft tooth and a threaded rod section connected with the shaft tooth are sequentially arranged on the pop-rivet. According to the shaft tooth hobbing fixture driven by the hydraulic tensioning end face, the shaft tooth is tensioned on the fixture base assembly through the pop-rivet and the pull rod assembly, the shaft tooth is positioned through the locating plane on the fixture base assembly and the shaft neck section on the pop-rivet, clamping and positioning of the shaft tooth are stable, and precision is high. The pull rod is pushed up and down through an oil cylinder on a workbench to form up-down movement so that the shaft tooth can be tensioned and loosened, clamping is convenient and fast, and working efficiency is high. Three jaws of the fixture shaft tooth in a traditional fixture are omitted in the fixture, the fixture cannot interfere with a hob in the machining process, and thus the universality of the fixture is improved.
Description
Technical field
The utility model relates to a kind of frock, particularly a kind of gear hobbing frock.
Background technology
When tradition machining large-modulus few-tooth axle tooth, the large end of axle tooth upward, small end down, with top up and down, gear is positioned, turn gripper chuck mandrel tooth with three.
In the time of clamping axle tooth, because upper and lower top taper seat is difficult to the accuracy that assurance is located, therefore in clamping process, need repeatedly to calibrate, then manually use scroll chuck clamping work pieces, and when clamping work pieces, due to the impact of the precision of scroll chuck own, can not guarantee clamp after positioning precision and the uniformity of upper and lower top precision.
Simultaneously the versatility of this installation way is poor, and the axle tooth of different length, under the clamping mode of scroll chuck, can cause gear hobbing to add man-hour hobboing cutter and produce interference with scroll chuck.
To sum up, the precision of traditional axle tooth positioning clamping device is unstable, and clamping operating efficiency is low, and versatility is low.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of hydraulic tensioning end face driving shaft tooth gear-hobbing clamp, the problem such as the positioning precision that traditional axle tooth gear-hobbing clamp exists is unstable to solve, clamping inefficiency, versatility are poor.
The utility model hydraulic tensioning end face driving shaft tooth gear-hobbing clamp, comprise clamping fixture seat composition, pull bar composition, pulling claw and blind rivet, on described clamping fixture seat composition, be provided with the plane of orientation of locating shaft increment face, the locating hole vertical with plane of orientation and the pull bar composition installing hole being communicated with locating hole, described blind rivet is connected with pull bar composition by pulling claw, is disposed with the location shaft shoulder section, the axle journal section at locating shaft tooth center and the spiro rod section of connecting axle tooth that coordinate with locating hole on described blind rivet.
Further, described clamping fixture seat composition comprises the positioning seat, supporting seat and the base that connect successively, and described plane of orientation and locating hole are arranged on positioning seat.
Further, described pull bar composition comprises the lower link that is arranged in base and the upper connecting rod that is arranged in supporting seat, and upper connecting rod is connected by screw thread pair with lower link.
Further, on described upper connecting rod and lower link, be provided with axially directed groove, on described supporting seat and base, be provided with the guider screw being slidably matched with gathering sill.
The beneficial effects of the utility model: the utility model hydraulic tensioning end face driving shaft tooth gear-hobbing clamp, its clamping fixture seat composition is fixed on the workbench of gear-hobbing machine, and plane of orientation and the depth of parallelism of table plane and the axiality of locating hole and workbench on calibration clamp seat composition; Axle tooth by the tension of blind rivet and pull bar composition on clamping fixture seat composition, and axle journal section location on the plane of orientation and the blind rivet that form by clamping fixture seat, axle tooth clamping positioning stablity, precision are high; Moved up and down and can be strained and loosen axle tooth by the upper and lower pushing drawing rod composition of oil cylinder of workbench, convenient mounting and clamping is quick, and operating efficiency is high; And this fixture has been cancelled the three-jaw of clamp shaft tooth in conventional brace, and in process, fixture can not interfere with hobboing cutter, has improved the versatility of fixture.
