Abstract
The invention discloses a kind of car bridge driven pulley drilling tool, including bottom plate, body, support backing plate, spring rise piece, gland, screw rod, locking nut；Body and screw rod are fixed on bottom plate；Support backing plate is fixed on body；The top of body provided with support backing plate is risen piece provided with spring, and spring rises the endoporus and body fits of piece, is enclosed on body；Gland rises piece endoporus, body inner hole with spring respectively, is nested together；Locking nut is located on gland.Rise piece and body, gland of the spring of this frock coordinates accurate, and the spring piece stress that rises struts rear gripper endoporus, with driven gear inner hole gapless, eliminates positioning origin error, makes the hole group position degree after drilling stable；Convenient mounting and clamping：Any part need not be taken, workpiece can be taken down by unclamping locking nut.
Description
Technical field
The present invention relates to machining technology field, specifically a kind of car bridge driven pulley drilling tool.
Background technology
Originally during the processing of car bridge driven wheel bore group, the tool structure that uses form for bottom plate, cushion block, positioning head, screw rod,
Pressing plate, open washer, locking nut.Bottom plate is fixed by screws on the workbench of lathe, and positioning head, cushion block, screw rod pass through
Screw is fixed on bottom plate.During processing, driven gear endoporus positions by positioning head, is compressed by locking nut stress after pressing plate
Driven gear end face processes.Due to fixture be using positioning head as origin benchmark centering center, and positioning head and spiral bevel gear from
Moving gear inner hole has gap, causes driven gear endoporus center and origin center inconsistent, so as to cause with a collection of gear
Position degree after drilling is inconsistent, and the size of its fit clearance directly affects the position degree after drilling.And each completion of processing
Pressing plate, open washer will be removed, clamping is inconvenient.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and a kind of car bridge driven pulley drilling tool is provided, should
Frock can solve that driven gear hole location is inconsistent and the inconvenient phenomenon of clamping.
Realizing the technical scheme of the object of the invention is：
A kind of car bridge driven pulley drilling tool, including bottom plate, body, support backing plate, spring rise piece, gland, screw rod, locking screw
It is female；Body and screw rod are fixed on bottom plate；Support backing plate is fixed on body；The top of body provided with support backing plate is provided with bullet
Spring rises piece, and spring rises the endoporus and body fits of piece, is enclosed on body；Rise respectively with spring piece endoporus, body endoporus of gland is matched somebody with somebody
Close, be nested together；Locking nut is located on gland.
Described spring rise piece endoporus and body locating shaft coordinate.
Described body, screw rod and support backing plate, is fixed by screw.
Beneficial effect：（1）Rise piece and body, gland of the spring of this frock coordinates accurate, and spring, which rises after piece stress struts, to be pressed from both sides
Tight bore, with driven gear inner hole gapless, positioning origin error is eliminated, makes the hole group position degree after drilling steady
It is fixed；（2）Convenient mounting and clamping：Any part need not be taken, workpiece can be taken down by unclamping locking nut.
Brief description of the drawings
Fig. 1 is a kind of structural representation of car bridge driven pulley drilling tool of the present invention；
In figure, the spring of 1. screw rod, 2. locking nut, 3. gland 4. rise piece 5. process part 6. support the body 8. of backing plate 7.
The locating shaft of bottom plate 9..
Embodiment
The present invention is further elaborated with reference to the accompanying drawings and examples, but is not limitation of the invention.
Embodiment：
As shown in figure 1, a kind of car bridge driven pulley drilling tool, including bottom plate, body, support backing plate, spring rise piece, gland,
Screw rod, locking nut；Body and screw rod are fixed by screws on bottom plate；Support backing plate is fixed by screws on body；If
The top for having the body of support backing plate is risen piece provided with spring, and spring rises by the endoporus of piece and the locating shaft 9 of body coordinates, and is enclosed on body
On；Gland rises piece endoporus, body inner hole with spring respectively, is nested together；Locking nut is assemblied on gland.
In use, first bottom plate is screwed on the workbench of drilling hole machine tool, then by screw rod screw, the bottom of installed in
On plate, support backing plate and body on the basis of the locating shaft 9 of body first with again on bottom plate, being beaten after together with screw attachment
Table takes positioning origin, and then the spring piece that rises is inserted on the locating shaft 9 of body, gland is finally inserted in, screws on locking nut.Processing
When, processing part driven gear is put on fixture, when tightening locking nut, gland stress rises piece in spring, spring is risen
Piece struts, so as to which gripper endoporus is processed.During completion of processing, when unclamping locking nut, spring rises after piece cancellation stress
Reduce, so as to loosen workpiece.
