Abstract
Bore cross hole tool the utility model discloses a kind of car bridge driving gear, including pedestal, babinet, sleeve, bearing pressure ring, bearing, movable drill bushing, handle brackets, handle, to determining device flange sleeve, to rationed marketing, compressed spring, spring capping.Babinet is fixed on the base, and is fixed again with bearing pressure ring in indentation babinet after sleeve assembly bearing, running drill is applied mechanically screw and is fixed on babinet；Handle brackets, handle, to determining device flange sleeve, locking mechanism and being fixed on babinet to rationed marketing, compressed spring, spring capping composition indexing.This tooling indexing mechanism is independent and closes, and is not interfered by outside environmental elements；Wedge shape springs into card slot by spring to rationed marketing and realizes precisely indexing, even inclined-plane is worn, can also eliminate gap automatically under spring force keeps indexing accurate；Workpiece rotation is driven by bearing, light and handy flexible；Handle drives indexing wedge shape to rationed marketing, and indexing action simplicity is coherent, easily operated.
Description
Technical field
The present invention relates to technical field of mechanical processing, specifically a kind of car bridge driving gear bores cross hole tool.
Background technology
When original car bridge driving gear bores cross through hole, the tool structure group of point No. 4 brills, use becomes pedestal, determines
Position set, bolt, spitting drill bushing, movable drill bushing.Pedestal is fixed by screws on the workbench of lathe, positioning sleeve by screw with
Pedestal is connected and fixed, and spitting drill bushing, running drill are applied mechanically screw and be fixed on positioning sleeve.When processing, using the hole after drilling through as point
Spend datum hole, coordinated using bolt and the interporal lacuna that drills through and indexed, often bore 1 hole will rotational workpieces and be inserted into bolt be drilled
In hole, it need to rotate 3 times.The tooling has the following disadvantages：Workpiece and positioning sleeve endoporus friction, rotation are dumb；After bolt abrasion
Gap becomes conference and accumulated error is caused to increase and make bolt that can not penetrate through pin hole；Aperture is jagged not only to be influenced indexing accuracy and makes
It is difficult to plug at bolt, reduces production efficiency.It can not observe whether bolt is inserted into pin hole when being inserted into due to bolt, be easy to cause
It is bore, bore partially or leak and bore more.
Invention content
It is an object of the invention to overcome the deficiencies in the prior art, and provide a kind of car bridge driving gear brill cross bore work
Dress, the tooling can solve cross pore size wild effect and improve production efficiency.
Realizing the technical solution of the object of the invention is：
A kind of car bridge driving gear bores cross hole tool, including babinet and be fixed on babinet sleeve, bearing, activity
Drill bushing, unlike the prior art：Indexing locking mechanism is additionally provided on babinet, the indexing locking mechanism is by handle, handle
Holder, to determining device flange sleeve, connecting composition jointly to rationed marketing, compressed spring, spring capping, to determine device flange sleeve endoporus with to fixed
Major diameter fit is sold, the indexing card slot of rationed marketing lozenges and sleeve is coordinated, and spring into indexing card slot under the action of compressed spring
It is interior, rationed marketing bottom end is connect with handle, handle is fixed on by handle brackets on babinet, and sleeve and bearing assembly connection simultaneously use axis
Bearing ring is fixed.
The sleeve outer diameter coordinates with brearing bore, bearing outside diameter and babinet inner hole.
The indexing card slot inclined-plane to rationed marketing wedge face and sleeve coordinates.
Beneficial effects of the present invention：（1）New tooling indexing mechanism is independent and closes, and is not interfered by outside environmental elements；Wedge
Shape springs into card slot by spring to rationed marketing and realizes that precisely indexing can also disappear automatically under spring force even inclined-plane is worn
Except gap, keep indexing accurate.（2）Workpiece rotation is driven by bearing, light and handy flexible.（3）Handle drives indexing wedge shape to rationed marketing, divides
Degree action is easy to be coherent, and easily operated single products, production efficiency is obviously improved.
Description of the drawings
Fig. 1 is the structural schematic diagram that a kind of car bridge driving gear of the present invention bores cross hole tool；
Fig. 2 is B-B direction sectional view in Fig. 1.
In figure, 1. 5. bearing of processing part 2. sleeve, 3. lock-screw, 4. bearing pressure ring, 6. babinet 7.
Movable drill bushing 8. is to rationed marketing 9. to determining 10. compressed spring of device flange sleeve, 11. spring capping, 12. handle 13.
14. pedestal of hand holder.
Specific implementation mode
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 Figs. 1-2, a kind of car bridge driving gear bores cross hole tool, including pedestal, babinet, sleeve, bearing pressure
Ring, bearing, movable drill bushing, handle brackets, handle, to determining device flange sleeve, to rationed marketing, compressed spring, spring capping.Babinet is fixed
On pedestal, fixed again with bearing pressure ring in indentation babinet after sleeve assembly bearing, running drill is applied mechanically screw and is fixed on babinet；
Handle brackets, handle, to determining device flange sleeve, locking mechanism and being fixed on case to rationed marketing, compressed spring, spring capping composition indexing
On body, to determining device flange sleeve endoporus and to rationed marketing major diameter fit, coordinating the indexing card slot inclined-plane of rationed marketing lozenges and sleeve, and
It springs into indexing card slot, rationed marketing bottom end is connect with handle, handle is fixed on by handle brackets under the action of compressed spring
On babinet.
In use, being screwed entire tooling on the workbench of drilling hole machine tool.When processing, actively by processing part
Gear is put into the sleeve of fixture, tightens lock-screw, after boring what a hole, so that indexing locking mechanism is put by toggle handle
Pine, turning of work piece, which makes to be caught in after next indexing trough rationed marketing, unclamps handle, and indexing locking mechanism locking drills again.
