Description
Technical field
This utility model is related to machining technique field, ensures the sprocket wheel that processes in more particularly to a kind of sprocket wheel course of processing
Key slot center and the alignment device of teeth groove center aligning accuracy.
Background technology
Sprocket wheel is widely used in the machine driving of the industries such as chemical industry, textile machine, food processing, instrument, oil
Deng the profile of tooth of sprocket wheel must assure that chain energy-conservation steadily enters and exit engagement freely, and chain link when reducing engagement is rushed as far as possible
Hit and contact stress, sprocket wheel is installed with axle typically by key, therefore, is required on usual sprocket wheel when installing fixed
Processing keyway, in the higher occasion of some service precisions, the center of keyway needs the center pair with corresponding external tooth
Position, it is impossible to which more than design tolerance, this processing request to sprocket wheel key teeth is just very high, should consider requirement on machining accuracy, colleague
Take into account working (machining) efficiency again, this problem is solved without particularly preferred method also during processing at present, is usually gone out
The situation that existing precision can not be taken into account with working (machining) efficiency, the sprocket wheel fraction defective of processing are very high, scrap many, cause the liter of production cost
High.
Utility model content
For the problem in the existing course of processing, the utility model proposes a kind of steering sprocket key groove processing key teeth center para-position dress
Put, which can meet the problem of machining accuracy and machining production efficiency simultaneously.
For reaching the purpose of this utility model, a kind of steering sprocket key groove processing key teeth center alignment device bag of the present utility model
Positioning disk is included, which is fixed with lathe, the center of positioning disk is provided with groove；The broaching guide pin bushing being connected with positioning disk, guide pin bushing of broaching
Cutter groove center and the center superposition of groove；Centrosymmetric T-shaped piece broaching guide pin bushing is positioned in the groove of positioning disk, described
T-shaped piece of transverse width dimension is consistent with the width of positioning disk groove, the width of the cutter groove of vertical width dimensions and broaching guide pin bushing
Consistent size；To tooth block, when product to be processed is placed on broaching guide pin bushing, the groove for being arranged on positioning disk to tooth block
Interior, and the cylinder on tooth block and sprocket indentations bottom are coincide.
The beneficial effects of the utility model are that steering sprocket key groove processing key teeth center alignment device, simple structure are operated
Easily, and the high precision processed, can make that production efficiency is greatly improved and maximum possible reduces defective products rate,
Save production cost.

Centrosymmetric T-shaped piece 6 in groove 102, T-shaped piece of 6 transverse width dimensions are consistent with the width of positioning disk groove 102, erect
Consistent with the width dimensions of the cutter groove 7 of broaching guide pin bushing to width dimensions；To tooth block 4 (referring to Fig. 3 and Fig. 4), when chain to be processed
When wheel 5 is placed on broaching guide pin bushing 3, in the groove 102 to tooth block 4 in the middle of the positioning disk 1, and on tooth block 4
Cylinder 401 and sprocket indentations bottom coincide.Wherein, the diameter and sprocket indentations bottom arc diameter to tooth block cylinder 401
Equivalently-sized
According to a kind of steering sprocket key groove processing key teeth center alignment device of an above-mentioned embodiment, sprocket wheel of the present utility model
Keyway processing key teeth center alignment method comprises the steps：
Step 1, positioning disk 1 and lathe are connected；
Step 2, broaching guide pin bushing 3 and positioning disk 1 are connected, center and the positioning disk groove 102 of the cutter groove 7 of guide pin bushing 3 of broaching
Center superposition；
Step 3：By T-shaped piece of insertion positioning disk groove 102 and the cutter groove 7 of broaching guide pin bushing 3, cutter groove 7 and positioning disk groove is made
102 center superpositions；
Step 4, clamping processed product, i.e. sprocket wheel 5, place it on broaching guide pin bushing 3；
Step 5, tooth block 4 will be attached in the groove in the middle of positioning disk 1, adjust the upper-lower position to tooth block 4, make to tooth
Cylinder 401 and sprocket indentations bottom on block 4 coincide；
Step 6, keyway broach 2 is put into, starts keyway of broaching.
One preferred embodiment in, in steps of 5, also include using thin slice clearance gauge in positioning disk groove 102
The step of center micro-adjustment is carried out to tooth block.
Steering sprocket key groove processing key teeth center of the present utility model alignment device, using transverse width dimension and positioning disk groove
Width is consistent, T-shaped piece consistent with guide pin bushing cutter groove width dimensions of vertical width dimensions, and positioning disk and broaching guide pin bushing can be made quick
Center is found accurately, and efficiency is greatly promoted；And overlapped using the cutter groove center and product gear groove center that ensure that broaching guide pin bushing to tooth block,
