Description
Technical field
The present invention relates to gear shaving processing technique field, be specifically related to a kind of gear shaving fixed mechanism.
Background technology
Gear is the intermeshing machine components having tooth of energy, and being wheel rim has tooth can engage the mechanical organ transmitting motion and power continuously; Gear use is in the car very frequent, and Shaving Process is the principle of the helical gear engagement do not waited according to a pair helical angle, gear shaver with intersected an angle by the axial space of gear cutting machine, their engagement is the free generating motion without the two-sided engagement of sideshake.In engaged transmission, due to the existence of Axis Cross angle " φ ", between the flank of tooth, producing Relative sliding along teeth directional, this sliding velocity v cuts=and (vt2-vt1) be the cutting speed of Shaving Process.The flank of tooth of gear shaver is slotted and forms blade, by sliding velocity by the allowance excision on gear teeth face.Owing to being two-sided engagement, machining can be carried out in the two sides of gear shaver, but due to the cutting angle of two sides different, side is acute angle, and cutting power is strong; Opposite side is obtuse angle, and cutting power is weak, to extrude polishing, therefore has considerable influence to shaving quality.Same shave condition is obtained for making gear both sides, then in shaving process, gear shaver does alternately rotating campaign, at present in the Shaving Process of gear, existing gear shaving fixed mechanism cannot firmly fix gear fast, causes gear shaving working (machining) efficiency low.
Summary of the invention
The invention is intended to provide a kind of gear shaving fixed mechanism, with firm grip gear.
Gear shaving fixed mechanism in this programme, comprises the right side sets gradually from a left side vertically axle, waveform expansion set, gland and drive unit, axle comprises the clamping part from left to right distributed successively vertically, the shaft shoulder and fixed part, wherein removably connect between clamping part and lathe, the shaft shoulder can carry out end face location to gear, waveform expansion set is enclosed within fixed part, waveform expansion set comprises the distortion swelling portion and supporting part that from left to right distribute successively vertically, distortion swelling portion can be out of shape and axial deflection is converted into radial-deformation by axial stretching, gland comprises columnar body and is positioned at the boss of columnar body outside, columnar body and supporting part endoporus matched in clearance, boss is then against on supporting part outer face, the axial gap of columnar body and fixed part right-hand member is greater than the axial deflection of waveform expansion set, drive unit can drive gland to move vertically.
The advantage of this programme is: comprise the right side sets gradually from a left side vertically axle, waveform expansion set, gland and drive unit, axle comprises the clamping part from left to right distributed successively vertically, the shaft shoulder and fixed part, wherein removably connect between clamping part and lathe, be fixed by chuck or triangle chuck between clamping part and lathe, the shaft shoulder can carry out end face location to gear, waveform expansion set is enclosed within fixed part, waveform expansion set comprises the distortion swelling portion and supporting part that from left to right distribute successively vertically, distortion swelling portion can be out of shape and axial deflection is converted into radial-deformation by axial stretching, gland comprises columnar body and is positioned at the boss of columnar body outside, columnar body and supporting part endoporus matched in clearance, boss is then against on supporting part outer face, the axial gap of columnar body and fixed part right-hand member is greater than the axial deflection of waveform expansion set, in case gland movement locus and axle fixed part interfere in gland slip compressed waveform expansion set process, avoid gland cannot compress waveform expansion set, drive unit can drive gland to move vertically, make gear clamping rapider.
During work, by geared sleeve on waveform expansion set, gear left side is against on shaft shoulder right side and locates, then accessory drive drives gland to compress waveform expansion set supporting part, make waveform expansion set homogeneous deformation swelling gear, can Shaving Process be carried out, after machining, accessory drive is only needed to remove gland, waveform expansion set automatically resets, and is unclamped by gear, can take off gear, this programme structure is simple, processing ease, can firm clamping gear workpieces, is convenient to quick shaving, improve gear workpieces Shaving Process efficiency, reduce costs.
Further, positioning sleeve is surrounded by outside the shaft shoulder, positioning sleeve comprises the sidewall be enclosed within the shaft shoulder and the base plate be enclosed within outside waveform expansion set, during gear clamping, gear face is against on positioning sleeve and positions, in case when waveform expansion set left side, gear left side are all against on the shaft shoulder, gear left side can, against injustice, cause mismachining tolerance larger.
Further, fixed by pin between positioning sleeve sidewall and the shaft shoulder, facilitate installing/dismounting.
Further, axle clamping part left side is provided with cone-shaped inner hole, and thimble can withstand in cone-shaped inner hole and feel relieved to this fixed mechanism.
Further, described drive unit is hydraulic cylinder, and bearing capacity is strong, handled easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: axle 1, pin 2, positioning sleeve 3, waveform expansion set 4, gland 5.
Embodiment one is substantially as shown in Figure 1: gear shaving fixed mechanism comprises vertically from left and that the right side sets gradually axle 1, waveform expansion set 4, gland 5 and hydraulic cylinder, axle comprises the clamping part from left to right distributed successively vertically, the shaft shoulder and fixed part, wherein removably connect between clamping part and lathe, be fixed by chuck or triangle chuck between clamping part and lathe, axle clamping part left side is provided with cone-shaped inner hole, thimble can withstand in cone-shaped inner hole and feel relieved to this fixed mechanism, positioning sleeve 3 is surrounded by outside the shaft shoulder, positioning sleeve comprises the sidewall be enclosed within the shaft shoulder and the base plate be enclosed within outside waveform expansion set, fixed by pin 2 between positioning sleeve sidewall and the shaft shoulder, facilitate installing/dismounting, during gear clamping, gear face is against on positioning sleeve and positions, in case waveform expansion set left side, when gear left side is all against on the shaft shoulder, gear left side can against injustice, cause mismachining tolerance larger, waveform expansion set is enclosed within fixed part, waveform expansion set comprises the distortion swelling portion and supporting part that from left to right distribute successively vertically, distortion swelling portion can be out of shape and axial deflection is converted into radial-deformation by axial stretching, gland comprises columnar body and is positioned at the boss of columnar body outside, columnar body and supporting part endoporus matched in clearance, boss is then against on supporting part outer face, the axial gap of columnar body and fixed part right-hand member is greater than the axial deflection of waveform expansion set, in case gland movement locus and axle fixed part interfere in gland slip compressed waveform expansion set process, avoid gland cannot compress waveform expansion set, hydraulic cylinder can drive gland to move vertically, make gear clamping rapider.
