Description
Technical field
The utility model is related to gear machining apparatus technical field, and in particular to the brill for processing gear lightening hole
Hole fixture.
Background technology
Multiple lightening holes would generally be beaten on gear when gear is processed, lightening hole is evenly distributed on the end face of gear,
Lightening hole be uniformly distributed be in order that gear can operationally run well without shifting, lightening hole be as its name suggests in order to
Mitigate the weight of gear, conveniently take in use and use.
At present, the mode that lightening hole is processed on gear typically uses drilling machine drilling, and brill is installed with drill press spindle
Head, electric machine main shaft drives drilling bit high-speed to rotate by belt pulley, so as to bore lightening hole on gear.Chinese Authorization Notice No. is
The patent of CN204584341U discloses a kind of rig for processing starting clutch gear face lightening hole, including water
Flat workbench and the main spindle box and stepper motor that are respectively and fixedly installed to the workbench two ends；Main shaft on the main spindle box
The center of chuck, is horizontally mounted tapered drill bit；On workbench between the main spindle box and stepper motor, two are provided with
The guide rail being parallel to each other；A connecting plate is installed with the motor shaft of the stepper motor, one is installed with connecting plate
Dividing head, clamping part is provided with the dividing head chuck of dividing head；The connecting plate is located on two guide rail, can do reciprocal fortune
It is dynamic；The taper drill bit and the dividing head chuck are relative；In the center line of the taper drill bit and the dividing head chuck
Heart line is parallel to each other.The clamping part of the equipment is arranged on dividing head chuck, and the side of chuck clamping clamping part is with fixed clamp
Portion, the bottom surface of clamping part does not support, so when gear is installed on the holder portion with taper drill bit to Gear Processing lightening hole,
The side stress of gear, then opposite side be susceptible to skew, now continue process remaining lightening hole, the lightening hole for processing
Precision is inaccurate, it is not uniform enough to be distributed.
Utility model content
The utility model is intended to provide a kind of boring grab for processing gear lightening hole so that processing gear lightening hole
When gear various pieces uniform force, will not occur gear deflection cause the loss of weight hole precision for processing situation not high.
To reach above-mentioned purpose, the drilling that the technical solution of the utility model is to provide for processing gear lightening hole is pressed from both sides
Tool, including pedestal and clamping part；The upper surface of the pedestal is provided with fixing axle, and the fixing axle upper end is provided with matching
Nut；The fixing axle is rotated with pedestal by fixing axle and is connected through the middle part of clamping part, clamping part；The clamping part
Upper surface is provided with annular groove；The side of the pedestal is provided with support, and support is provided with fixed work gear upper surface to be added side
Fixing device；The support is provided with and limits the locating part that clamping part is rotated.
Using above-mentioned technical proposal, gear is installed on the holder portion through fixing axle, because fixing axle is provided with nut, is twisted
Dynamic nut can fix gear will not deflect on the holder portion.Before to the side processing lightening hole of gear, using support
The locating part of upper setting limits clamping part and can fill makes clamping part not rotate in process, solid vertically in adjusting bracket
Determine the opposite side of device fixed gear, then when drilling through lightening hole the both sides of gear can stress, will not occur gear side deflection
The situation for causing loss of weight hole precision not high.Because the upper surface of clamping part is provided with annular groove, when lightening hole is processed using drill bit,
Drill bit through can be placed in annular groove after gear without directly with clamping part contact failure clamping part.Due to clamping part and pedestal
Connection is rotated, after a lightening hole is processed, the next lightening hole of processing by clamping part is rotated, it is convenient and swift.
Further, the side of the clamping part is provided with multiple cannelures for being uniformly distributed and coordinating with locating part.Clamping
The side in portion is provided with multiple cannelures, in locating part on support insertion cannelure can stationary gripping part make it in process
In be not moved, can be easily spacing to clamping part.
Further, the locating part is sliding block.Sliding block can horizontally slip on support, when needing stationary gripping part time shift
Movable slider is inserted into cannelure, extracts sliding block when needing and rotating clamping part, simple to operate, convenient and swift.
Further, the fixing device includes cylinder, piston and briquetting, and one end of the piston is connected with cylinder, separately
One end is connected with briquetting；The briquetting is located at the top of work gear side to be added.When side to gear processes lightening hole, operation
Cylinder makes piston move downward up to the briquetting on piston is contacted with the another side of gear, then the two of gear when drilling through lightening hole
Side can stress, will not be deflected to side.Cylinder operation is simple, briquetting is moved up and down, and effectively improves processing effect
Rate.
Further, it is carved with angle on the pedestal；The clamping part is marked with datum line.Due to being carved with angle on pedestal
Degree, the angle that clamping part is rotated can be accurately determined by the positioning of datum line.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
Fig. 1 is the utility model for processing the front view of the boring grab of gear lightening hole；
Fig. 2 is the top view of clamping part in Fig. 1.
Specific embodiment
Reference：Pedestal 1, clamping part 2, gear 3, fixing axle 11, nut 111, support 12, sliding block 121, cylinder 122,
