Abstract
The utility model discloses a ratholing clamping tool of an automobile gear box output shaft part solves the problems that the accuracy of a drilled hole is hard to guarantee and a workpiece can be easily wasted in processing an oblique hole of an existing automobile gear box output shaft part The ratholing clamping tool of the automobile gear box output shaft part comprises a base provided with a hydraulic pressure rod. The hydraulic pressure rod is perpendicular to the slope of the base. The slope of the base is provided with a divided circle. A lower terminal pad is arranged on the divided circle. And an upper terminal pad is fixedly arranged on the lower terminal pad. A positioning pin is arranged on the upper end face of the upper terminal pad in penetrating mode. A spring sleeve is sleeved on the upper portion of the upper terminal pad. A pull disc is sleeved on the lower portion of the upper terminal and connected with the hydraulic pressure rod. A pull claw is fixedly arranged on the upper end of the pull disc. A gap is arranged between a lower step face of the lateral of the pull disc and the upper end face of the lower terminal pad. The ratholing clamping tool of the automobile gear box output shaft part has the advantages that the circumferential location is achieved by the positioning pin, a workpiece does not displace when cut with strong cutting force because a hydraulic pressure clamping mechanism is added ,and the operation is convenient and saves labor and time.
Description
Technical field
The utility model relates to automobile gearbox output shaft part processing and uses auxiliary mould, is specially a kind of automobile gearbox output shaft part rat holing anchor clamps.
Background technology
One end of automobile gearbox output shaft part is a disc-shaped structure, and is that the center of circle is uniformly distributed with and has five circular holes with its axle center on this end face, and need on the inner cylinder face of circular hole, be drilled with inclined hole; The anchor clamps that the tradition rat holing is adopted are through axial location, and manually clam member guarantees that the workpiece that tilts does not squint, and circumferencial direction adopts the rotation of five alignment pin control parts; Simultaneously on the alignment pin drill bushing is housed, drill bit is played the effect of guiding, in the process; Because boring is the deep hole machining of diameter 5mm, and the drill bit tip is not in the plane, usually drill bit is broken and in workpiece, cause the useless problem of decreasing of workpiece; Simultaneously, borehole accuracy is difficult to guarantee.
Summary of the invention
The utility model is prone to cause that workpiece is useless decreases and problem that borehole accuracy is difficult to guarantee when solving existing automobile gearbox output shaft part tooling processing inclined hole, and a kind of automobile gearbox output shaft part rat holing anchor clamps are provided.
The utility model is to adopt following technical scheme to realize: automobile gearbox output shaft part rat holing anchor clamps; Comprise the base that is fixed on the lathe working face, be provided with the hydraulic stem vertical in the base, and the axis with hydraulic stem is that the center of circle is provided with index dial on the inclined-plane of base with its inclined-plane; Be fixed with down terminal pad on the index dial; Be fixed with terminal pad on the following terminal pad, last terminal pad upper surface is installed with alignment pin, and last terminal pad top has the diminishing taper endoporus of diameter from top to down; And be with the spring housing that is mated in the taper endoporus of last terminal pad; Last terminal pad bottom has cylindrical bore, and is with the dish that draws that is mated in the cylindrical bore of last terminal pad, draws dish to pass down terminal pad and is connected with hydraulic stem; Draw the dish upper end to be fixed with the pulling claw that is stuck on the spring housing lateral wall, and leave the gap in drawing between dish outside downstairs face and the following terminal pad upper surface above the following terminal pad.
Carry out inclined hole and add man-hour, the machining hole of workpiece (being automobile gearbox output shaft part) is put into spring housing to the position of living alignment pin, realize the circumferential registration of workpiece through location, a place; Drive hydraulic stem through hydraulic mechanism this moment and shrink, pulling claw drives spring housing and moves down, and under the effect of last terminal pad taper endoporus, the spring housing internal diameter dwindles, and workpiece is stepped up, and realizes the workpiece axial location; Draw gap between dish cascaded surface and the following terminal pad upper surface to limit the contraction scope of spring housing diameter, be prone to cause workpiece to give up when having overcome existing automobile gearbox output shaft part tooling processing inclined hole problem that damage and borehole accuracy be difficult to guarantee.
Last terminal pad is fixed with dust cover on the upper surface, has on the dust cover and wears workpiece hole, prevents that iron filings are splashed to anchor clamps inside.
The utility model reasonable in design is reliable, realizes that through rotation-indexing table workpiece five holes add the requirement of the automatic rotation in man-hour, and No. one time clamping can be processed five holes; And workpiece adopts a place alignment pin to realize circumferential registration, can remove alignment pin everywhere, reduces the location replication problem; Very firm; And increase hydraulic clamp mechanism and guarantee that workpiece adds and receive strong cutting force man-hour and can not squint, improved the hole site precision well, the rate 50% of reducing the number of rejects and seconds; Have simple operation and time saving and energy saving advantage, working (machining) efficiency has improved 30%.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the 1-base, the 2-hydraulic stem, the 3-index dial, terminal pad under the 4-, the last terminal pad of 5-, the 6-alignment pin, the 7-spring housing, 8-draws dish, 9-pulling claw, 10-dust cover.
The specific embodiment
Automobile gearbox output shaft part rat holing anchor clamps; Comprise the base 1 that is fixed on the lathe working face, be provided with the hydraulic stem vertical 2 in the base 1, and the axis with hydraulic stem 2 is that the center of circle is provided with index dial 3 on the inclined-plane of base 1 with its inclined-plane; Be fixed with down terminal pad 4 on the index dial 3; Be fixed with terminal pad 5 on the following terminal pad 4, last terminal pad 5 upper surfaces are installed with alignment pin 6, and last terminal pad 5 tops have the diminishing taper endoporus of diameter from top to down; And be with the spring housing 7 that is mated in the taper endoporus of last terminal pad 5; Last terminal pad 5 bottoms have cylindrical bore, and go up be with in the cylindrical bore of terminal pad 5 be mated draw dish 8, draw dish 8 to pass down terminal pad 4 and be connected with hydraulic stem 2; Draw dish 8 upper ends to be fixed with the pulling claw 9 that is stuck on spring housing 7 lateral walls, and drawing between dish 8 outside downstairs faces and following terminal pad 4 upper surfaces above following terminal pad 4 left the gap.
Last terminal pad is fixed with dust cover 10 on 5 upper surfaces, has on the dust cover 10 and wears workpiece hole.
