Description
Technical field
The utility model is related to clamping, the supporting, positioner field of workpiece or cutter, and in particular to a kind of gear drilling
Frock.
Background technology
Gear is that with teeth can continuously engage transmits motion and the mechanical organ of power on wheel rim, is mutually engageable with teeth
Machine components, the use of gear for most mechanical device, serves very important effect.Therefore, gear
Processing and manufacturing will be very strict, gear, it is necessary to punched on the end face of gear, is easy to injection to moisten after the completion of casting
Lubricating oil etc..In drilling, it is necessary to which gear is clamped.When clamping, claw or other fixtures clamped gear in the past
It is circumferential, the tooth root of gear is so on the one hand not only easily damaged, different folders are on the other hand needed for different types of gear
Have to be clamped, it is necessary to manufacture different fixtures, waste of resource.In addition when being punched to gear, it is necessary to ensure hole
Position on the tie point of two tooth roots and the line of gear centre, and existing frock can only realize clamping, it is impossible to carry out
Positioning.
Utility model content
The purpose of this utility model is to provide a kind of gear drilling tool, this frock performance accuracy when carrying out gear
Height, and it is simple to operate.
To reach above-mentioned purpose, base case of the present utility model is as follows：A kind of gear drilling tool, including positioning bottom
Plate, positioning supporting plate and bolt；It is described positioning supporting plate include horizontal segment and vertical section, the horizontal segment and vertical section one into
Type and horizontal segment and vertical section are vertically arranged, and the positioning plate is arranged on the top of horizontal segment and is fixedly connected with horizontal segment,
The pressing plate for fixed gear is provided with above the positioning plate, the vertical section top, which is provided with, is used for what gear was positioned
It is provided with the middle part of location division, the pressing plate in the middle part of through hole, the positioning plate and is provided with screwed hole, the screwed hole connects with bolt thread
Connect.
Operation principle of the present utility model and have the beneficial effect that：When being drilled to gear, positioning can be supported
Plate is placed on workbench, and fixed plate can also be placed on lathe, is easy to processing.Positioning the horizontal segment of supporting plate is used for branch
Support positioning plate.In drilling, gear is fixed using this frock.When fixing, first pressing plate is pulled down, gear is placed
Onto positioning plate, and make the position point in vertical section between two gear teeth of gear, complete the positioning to gear.Because
Horizontal segment is vertical with vertical section, it is ensured that the accuracy of positioning.Then cover pressing plate, with bolt thread end pass through through hole after with
Screwed hole is threadedly coupled, and tightens bolt, and now pressing plate just firmly compresses gear, just can be drilled.
The utility model, come fixed gear, can be accurately positioned with pressing plate to various sizes of gear, and this is to pass through
Position point is between two gear teeth, i.e., connecting portion offsets with tooth root, registration.
Preferred scheme one：Based on scheme preferred scheme, the positioning plate is detachable by screw with horizontal segment
Connection, so convenient connection, and can be convenient for changing.
Preferred scheme two：Preferably one preferred scheme, the positioning supporting plate bottom is provided with T-connecting piece, T
Shape connector is conveniently installed on lathe, is easy to processing.
Preferred scheme three：Preferably two preferred scheme, the through hole includes circular hole and bar hole, the circular hole
Connected with bar hole, when compressing, circular hole is easy to passing through for bolt, and bar hole is then beneficial to bolt and produces relative position with pressing plate
Move, be moved easily.
Preferred scheme four：Preferably one preferred scheme, the positioning plate is provided with gutter channel, to gear
, it is necessary to spray water to cool down when being drilled, and gutter channel is then beneficial to the discharge of water.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model gear drilling tool embodiment.
Embodiment
The utility model is described in further detail below by embodiment：
Reference in Figure of description includes：Positioning plate 1, T-connecting piece 2, horizontal segment 3, vertical section 4, positioning
Portion 5, gear 6, pressing plate 7, bar hole 8, circular hole 9.
Embodiment is substantially as shown in Figure 1：A kind of drilling tool of gear 6, including positioning plate 1, positioning supporting plate and spiral shell
Bolt；Positioning supporting plate includes horizontal segment 3 and vertical section 4, and horizontal segment 3 and vertical section 4 are integrally formed and horizontal segment 3 and vertical section 4
It is vertically arranged, positioning plate 1 is arranged on the top of horizontal segment 3 and is fixedly connected with horizontal segment 3, the top of positioning plate 1 is provided with use
In the pressing plate 7 of fixed gear 6, the top of vertical section 4 is provided with the location division 5 for being used for being positioned to gear 6, and the middle part of pressing plate 7 is provided with
Through hole, the middle part of positioning plate 1 is provided with screwed hole, and screwed hole is connected with bolt thread.Positioning plate 1 passes through screw with horizontal segment 3
It is detachably connected, so convenient connection, and can be convenient for changing.Through hole includes circular hole 9 and bar hole 8, circular hole 9 and bar hole
8 connections, when compressing, circular hole 9 is easy to passing through for bolt, and bar hole 8 is then beneficial to bolt and produces relative displacement with pressing plate 7, side
Just move.
When being drilled to gear 6, positioning supporting plate can be placed on workbench, fixed plate can also be placed
On lathe, it is easy to processing.The horizontal segment 3 of positioning supporting plate is used to support positioning plate 1.In drilling, this frock pair is utilized
Gear 6 is fixed.When fixing, first pressing plate 7 is pulled down, gear 6 is placed on positioning plate 1, and is made in vertical section 4
