Be axially arranged with the endoporus through its both ends along fixing sleeve, it is described it is top be fixed in endoporus, top tip is stretched out outside endoporus；Institute
It states folder spring and the other end in fixing sleeve is set, folder spring is made of polylith sector fixture block, and the outer wall for pressing from both sides spring is the conical surface；The locking screw
Female one end inner wall is matched equipped with internal thread with fixing sleeve, and other end inner wall is and the folder matched conical surface of spring.This gear hobbing is pressed from both sides
Lamps structure is simple, easy to use, and manufacture is easy, and manufacturing cost is low, and clamping effect is good, and will not cause to damage to axis.
Although solve the problems, such as that apparatus for fastening is easy to generate damage, but said program to axis using the scheme of above-mentioned patent
Used in cannot the shaft gear different to the diameter of axle be clamped so that product clamping is single, and application range becomes smaller.
Utility model content
The purpose of this utility model is a kind of for shaft gear gear hobbing process tooling in offer, must not be to diameter of axle difference with solution
Shaft gear the problem of being clamped and the scope of application is caused to become smaller.
In order to achieve the above object, the base case of the utility model is：For shaft gear gear hobbing process tooling, including branch
Support and the cross bar being slidably connected on supporting rack, are equipped with positioning region between the cross bar and support frame as described above, on the cross bar
Equipped with cylindrical gripping sleeve, the gripping sleeve is equipped with axis hole along axial line, and being equipped with for the gripping sleeve is concentric with axis hole
Annular groove, the annular groove bottom are equipped with the first multiple identical and vertical duct, the lower end connection in first duct
There is the second duct being connected to axis hole, the exit in first duct is equipped with the first sliding block slidingly and sealingly connected, described

When force effect, the second sliding block is located in the second duct.
The operation principle of this base case is：Before processing shaft gear, first the axis of shaft gear one end is placed into axis hole；
Due to the clamping cap for being equipped with being flexibly connected in annular groove, so clamping cap is moved to annular groove bottom；Due to annular
The exit in the first identical circumferentially arranged with multiple structures and vertical duct of bottom portion of groove, the first duct is equipped with slidingly and sealingly
First sliding block of connection, when clamping cap moves down, the first sliding block is moved by the pressure of clamping cap into duct；Due to axis
Internal surface of hole is equipped with and inwardly offers the second duct, and the first duct is connected with the second duct, and the exit in the second duct is equipped with
The second sliding block slidingly and sealingly connected, therefore sealing system is formed in the first duct and the second duct, the movement of the first sliding block is led
The pressure in the first duct and the second duct is caused to increase；Since the second sliding block is located at when spring is not by external force in duct, so
Pressure increase can push the second sliding block to be moved to outside the second duct in second duct；Continue to move to clamping cap, the second sliding block is by axis
Axis is clamped from circumferential direction；The length in the second duct is stretched out by adjusting the second sliding block to carry out the shaft gear of the different diameters of axle
Clamping；By clamping cap to movement above annular groove, the pressure of the first sliding block of clamping cap pair reduces, and the first sliding block is in the first spring
Effect is lower to restore to the original state, and the second sliding block also restores to the original state under second spring effect.
The advantageous effect of this base case is：Multiple first ducts and the first sliding block are set in annular groove bottom, are led to
Crossing the clamping cap that moves to multiple first sliding blocks while can apply pressure, ensure the stress balance of each first sliding block；In axis hole
Surface offer the second duct being recessed inwardly, the second duct exit be equipped with sliding and connect with the second channel seal
The second sliding block, can utilize sealing system pass through the first sliding block drive the second sliding block move；Connect in the first sliding block and the first duct
Spring is connect, can guarantee that the first sliding block protrudes from the first duct when not being under pressure；Connect between the second duct and the second sliding block
It connects second spring and can guarantee that in the second duct, shadow is generated when not entering axis hole to axis when not by outer force effect for the second sliding block
It rings；Annular groove is connected through a screw thread with clamping cap, when screw-thread fit moves clamping cap, can accurately adjust the position of clamping cap,
And it is equal to the pressure of the first sliding block, to accurately adjust the position of the second sliding block, while it can prevent clamping cap from loosening and influencing
To the clamping effect of axis；Circumferentially arranged multiple second ducts and the second sliding block in axis hole can carry out week from different directions
Be fixedly clamped, increase clamping effect, at the same can the second sliding block number it is more, increase the contact area with axis, reduce pair
The damage of axial plane, and after completing shaft gear processing, the second sliding block can be drawn in the second duct by second spring, be convenient for
Processing next time.
Compared with prior art, the shaft gear of the different diameters of axle can be clamped in this programme, and operating process is convenient, can improve shaft gear
Processing efficiency.
Further, the cap upper surface that compresses is rod-shaped by being inserted into casing equipped with the casing for rotating clamping cap
Object can further move clamping cap using lever principle, to further be gripped to axis.
Further, the compression cap upper surface is equipped with straight slot, and pressure can further be rotated by being snapped by tablet in straight slot
Tight lid.
Further, the contact surface of the clamping cap and the first compact heap is equipped with soft material, soft material and the first sliding block
It is in contact, the abrasion to the first sliding block can be reduced.
Further, it is equipped with location nut between the cross bar and supporting rack, cross bar position can be fixed by location nut,
And then the fixed position of geometrical clamp, it is gripped convenient for the shaft gear to different length.
