3. vertical height h passing through to control Z axis coordinate to adjust emery wheel 122 rotation axiss to knuckle-tooth knife surface meets：H=R ' Cos θ, wherein, R ' is the radius of turn of emery wheel 122, and θ is become folder with the tangent plane of blade face contact position with horizontal plane by emery wheel 122 Angle, in the present embodiment, R '=200mm, θ=β=55 °, then h=R ' cos θ=200 × cos55 °=114.715mm；Then, select Select the tooth of an emery wheel 122, table is beaten by amesdial to flank and looks for benchmark it is ensured that flank vertical X axis direction；Then, adjust The coordinate of section X main shaft, Y-axis and Z axis, blade grinding blade face M of the tooth after controlling emery wheel 122 that knuckle-tooth knife is found accurately, cut Cut state as shown in Figure 10 and Figure 11.

In this step, during emery wheel 122 grinding blade face M, control emery wheel 122 full in feed speed ν of X-direction Foot：Wherein, b is knuckle-tooth knife thickness, unit mm, and R ' is the radius of turn of emery wheel 122, unit mm, and β is The tangent plane of blade face M becomes angle with blade face.In the present embodiment, b=2mm, R '=200mm, β=55 °, thenThis feed speed is to consider knuckle-tooth knife physical dimension itself and institute The factors such as grinding angle obtain, and meet this feed speed and require, and knuckle-tooth knife is less prone to chipping, blade deformation in grinding process Situations such as, blade face M fineness is of a relatively high, improves crudy and yield rate.

4. complete step 3. rear emery wheel 122 withdrawing, work piece actuating device 320 drives knuckle-tooth swivel to cross a profile angle, sand The blade of wheel 122 second tooth of feed grinding again, so repeatedly, after it's one week pasts knuckle-tooth swivel, completes blade mill with teeth Cut processing.

5. shut down, take off knuckle-tooth knife, complete the grinding of knuckle-tooth knife blade.

Knuckle-tooth knife edge quality after grinding is detected, each tooth cutting edge shape unification, no chipping, crimping situation occur, Blade face fineness is 0.8.

Embodiment 3

The present embodiment provide a kind of method for grinding of knuckle-tooth knife, using embodiment 1 knuckle-tooth knife computer controlled grinding machine to knuckle-tooth Knife blade carries out grinding, and the knuckle-tooth knife processed as shown in Figure 1, Figure 2 and Figure 3, needs to process blade face M of flank, should Blade face M is the arc surface that radius is R, and the tangent plane in blade face M centre position becomes β angle with blade face, in the present embodiment, R=40mm, β=60 °, and knuckle-tooth knife thickness is b=2.5mm.Concrete operation step is as follows：

1. first knuckle-tooth knife to be processed is installed on the fixture of work piece actuating device 320 fixing it is ensured that knuckle-tooth knife surface Level, drives knuckle-tooth swivel to move by workpiece motor 322, measures radial run-out, and ensure that radial run-out is not more than 0.02mm；Then adjust knuckle-tooth knife surface with the horizontal 5 ° of angles, concrete regulation process is：First rotational angle regulating block 323 The adjusting screw 326 at two ends, the line making their ends is with the horizontal 5 ° of angles, then unclamps workpiece motor cabinet 321 and Z axis cunning The connecting bolt of seat 313, when rotating clockwise workpiece motor cabinet 321, its upper surface is contacted with adjusting screw 326, finally locks work Part motor cabinet 321 and the connecting bolt of Z axis slide 313, that is, complete knuckle-tooth knife angular adjustment.

Then emery wheel 122 and freeing wheel 403 are selected, the radius meeting freeing wheel 403 is R=40mm, the rotation of emery wheel 122 Radius R '=220mm, and emery wheel 122 is installed in emery wheel driving means 120, freeing wheel 403 is installed to finishing main shaft 402 On.

In this step, the fixture of knuckle-tooth knife is divided into mold and lower mould, mold and lower mould is tooth disk-shaped structure, with The number of teeth of knuckle-tooth knife is identical, but the profile of tooth of each tooth is less than the profile of tooth of knuckle-tooth knife, to processing blade slot milling, knuckle-tooth cutter holder It is contained between mold and lower mould, and be fastened by bolts.This kind of structure, the position of the tooth of knuckle-tooth knife can be compacted, from And the flank of tooth will not flexural deformation or crimping in grinding process.

2. emery wheel driving means 120 drive emery wheel 122 to rotate, and finishing motor 401 passes through to repair main shaft 402 driving freeing wheel 403 rotations, emery wheel driving means 120 along X axis freeing wheel 403 near and so that emery wheel 122 is contacted with freeing wheel 403, emery wheel 122 Periphery be trimmed wheel and 403 repair out circular groove, the radius of this arc groove is R=40mm.

3. vertical height h passing through to control Z axis coordinate to adjust emery wheel 122 rotation axiss to the knuckle-tooth knife center of circle meets：H=R ' Cos θ, wherein, R ' is the radius of turn of emery wheel 122, and θ is become folder with the tangent plane of blade face contact position with horizontal plane by emery wheel 122 Angle, in the present embodiment, R '=220mm, θ=β=60 °, then h=R ' cos θ=220 × cos60 °=110mm；Then, select one The tooth of individual emery wheel 122, plays table by amesdial and looks for benchmark it is ensured that flank vertical X axis direction to flank；Then, adjust X master The coordinate of axle, Y-axis and Z axis, blade grinding blade face M of the tooth after controlling emery wheel 122 that knuckle-tooth knife is found accurately.

In this step, during emery wheel 122 grinding blade face M, control emery wheel 122 full in feed speed ν of X-direction Foot：Wherein, b is knuckle-tooth knife thickness, unit mm, and R ' is the radius of turn of emery wheel 122, unit mm, and β is The tangent plane of blade face M becomes angle with blade face.In the present embodiment, b=2.5mm, R '=220mm, β=60 °, then

4. complete step 3. rear emery wheel 122 withdrawing, work piece actuating device 320 drives knuckle-tooth swivel to cross a profile angle, sand The blade of wheel 122 second tooth of feed grinding again, so repeatedly, after it's one week pasts knuckle-tooth swivel, completes blade mill with teeth Cut processing.

5. shut down, take off knuckle-tooth knife, complete the grinding of knuckle-tooth knife blade.

Knuckle-tooth knife edge quality after grinding is detected, each tooth cutting edge shape unification, no chipping, crimping situation occur, Blade face fineness is between 0.8 and 0.4.

Example described in the utility model is only preferred implementation of the present utility model to be described, not to this reality It is defined with new spirit and scope, on the premise of without departing from this utility model design philosophy, this area engineering technology people Various modifications and improvement that member makes to the technical solution of the utility model, all should fall into protection domain of the present utility model.
