Abstract
The utility model discloses a keep off bit select connecting axle subassembly drilling frock, install a V molding die spare supporting shoe (2) on bottom plate (1), the 2nd V molding die spare supporting shoe (3), the 3rd V molding die spare supporting shoe (4), first cylinder hold -down mechanism (5), second cylinder hold -down mechanism (6), and first locating piece (7), second locating piece (8) and drill bushing mount pad (9), be provided with locating pin (10) that are used for inserting parking rocking arm ear shape hole on first locating piece (7), the elasticity tight round pin in top (12) that compresses tightly a spacer bit select connecting axle from the top slope is equipped with on second locating piece (8), drill bushing (11) are equipped with in drill bushing mount pad (9). Realized the brill of joining in marriage of present fender bit select connecting axle subassembly through this drilling frock, solved because of the inconsistent rate of doing over again that leads to the fact in the aperture of two connecting holes is big that manufacturing cost is high, the connecting pin comes off after the long -time work risk has improved machining precision and production efficiency, has practiced thrift the cost.
Description
Technical field
The utility model relates to automotive transmission parts machining equipment, is specifically related to a kind of drilling tool, selects to join brill connecting hole in connecting shaft component for processing gear.
Background technology
Shown in composition graphs 3-Fig. 4, gear selects connecting shaft component to select connecting axle A and parking rocking arm B two parts to form by gear.Gear is selected connecting axle A is provided with the first connecting hole, and parking rocking arm B is provided with the second connecting hole, and parking rocking arm B is sleeved on gear and selects on connecting axle A, and by both being locked together through the connecting pin C of the first connecting hole and the second connecting hole simultaneously.
Add man-hour, first the work in-process heart bores the first connecting hole on gear selection connecting axle A, then processes the second connecting hole on parking rocking arm B with milling machine, then assembly connection pin-and-hole.Parking rocking arm B is also provided with ear shape hole D.
The subject matter existed is: the processing needing the work in-process heart and milling machine complete respectively two connecting holes, and need two cover locating hole clamp for machining, working (machining) efficiency is low, and equipment cost is high; There is the situation that the aperture of two connecting holes is inconsistent, and cannot the dimensional requirement of Assurance component assembling, rework rate is large, and production cost is high, there is the risk that connecting pin comes off after working long hours.
Utility model content
The utility model improves for above-mentioned technical problem, and intending provides a kind of drilling tool selecting connecting hole on connecting shaft component for processing gear, can once join the processing of having bored two connecting holes, improve machining accuracy and production efficiency, and cost-saving.
For this reason, the technical scheme that the utility model adopts is: a kind of gear selects connecting shaft component drilling tool, comprise base plate, described base plate is provided with the first V-type workpiece support block selecting connecting axle front end for supporting gear, for supporting the second V-type workpiece support block in the middle part of gear selection connecting axle, the 3rd V-type workpiece support block of connecting axle rear end is selected for supporting gear, for compressing the first cylinder pressing mechanism that gear selects connecting axle from top, for compressing the second cylinder pressing mechanism that gear selects connecting axle from top, and first locating piece, second locating piece and drill bushing mount pad, described first locating piece is arranged between the first V-type workpiece support block and the second V-type workpiece support block, first locating piece is provided with the alignment pin for inserting parking rocking arm ear shape hole, second locating piece is arranged on the rear of the 3rd V-type workpiece support block, second locating piece is equipped with and compresses from inclined upward the elasticity tight lifting pin supporting gear selection connecting axle, described drill bushing mount pad is built with drill bushing.
Be preferably, the hole the second locating piece supplying elasticity tight lifting pin pass through is built with lining.Set up lining, the wearability of lining, higher than the second locating piece, has saved manufacturing cost, avoids may wear to the second locating piece simultaneously, uses for a long time, only need more resleeve.
During installation, first parking rocking arm being enclosed within gear selects on connecting axle, connecting axle is selected to be placed in first gear again, second, in the V-type groove of the 3rd V-type workpiece support block, alignment pin is inserted in the ear shape hole of parking rocking arm, the axis of connecting axle is selected to rotate to prevent parking rocking arm around gear, connecting axle is selected to push against gear by elasticity tight lifting pin, in case backstop position selects connecting axle to rotate around the axis of self, again by first, gear selects connecting axle to compress by the second pressing plate, finally select connecting axle and parking rocking arm to join to gear by drill bit through drill bushing more simultaneously and bore connecting pin installing hole.
The beneficial effects of the utility model are: design ingenious, mechanism is reliable, by join brill solve existing gear select connecting shaft component assembling time, inconsistent the caused rework rate in the aperture because of two connecting holes is large, production cost is high, the risk that after working long hours, connecting pin comes off.
