Description
Technical field
The present invention relates to a kind of processing technologys of heavy-duty car transmission shaft end face tooth terminal pad, belong to auto parts and components processing
Field.
Background technology
Transmission shaft connection plate is one of important component of heavy-duty car transmission shaft assembly, it plays the role of being connection and biography
Pass power and when the wheelbase between transmission output shaft and drive axle input shaft and the angle of cut change, it also can constant speed, reliable
Torque is passed to each drive axle, driving wheel by ground, so as to ensure the normally travel of vehicle.
Transmission shaft connection plate end-tooth traditional diamond-making technique is three kinds of broaching, slotting, milling processing technologys, is limited by processing
Mode self character, the end-tooth surface roughness and precision of the product after machining all are difficult to accomplish higher, general surface
Roughness is 3.2；The production efficiency of these three processing technologys is all relatively low simultaneously, and one slotting, Milling Process end-tooth workpiece need
10 minutes or so, one end-tooth workpiece of wire pulling method needed 4 minutes or so.
Therefore, a kind of processing technology of new heavy-duty car transmission shaft end face tooth terminal pad is designed, is improving the table of product
While the quality of face, production efficiency can also be improved, reduces processing and manufacturing cost, being that those skilled in the art are urgently to be resolved hurrily asks
Topic.
The content of the invention
It is low, raw to solve surface quality existing for heavy-duty car transmission shaft end face tooth terminal pad processing technology in the prior art
The problem of efficiency is low is produced, the present invention provides a kind of new processing technology, using following technical proposals：
A kind of processing technology of heavy-duty car transmission shaft end face tooth terminal pad, which is characterized in that comprise the following steps：
Step 1：Forging blank is first carried out be heat-treated-quenched；
Step 2：Forging blank after heat treatment is machined, face work and outer circle；
Step 3：Using wheel grinding mode, blank end face after the machining operation processes required tooth form；
Step 4：It bores, two earhole of boring；
Step 5：Four hole of drill end.
Preferably, it is ground in the step 3 using shaping Emery grains emery wheel.Further, the shaping Buddha's warrior attendant
Beautiful emery wheel is white fused alumina（WA）Forming grinding wheel, Wheel hardness 2200-2300HV, granularity 36-40, emery wheel machined surface shape meet
Required tooth form；End-tooth grinding machine spindle rated speed 2000r/min used, the circular runout of workbench edge<0.001 millimeter,

Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
The embodiment of the present invention is a kind of processing technology of heavy-duty car transmission shaft end face tooth terminal pad, for processing such as Fig. 1
To product shown in Fig. 3 --- heavy-duty car transmission shaft end face tooth terminal pad comprises the following steps：
Step 1：The blank is forging, and material is 40Cr steel, and forging blank is first heat-treated, the heat treatment quenching and tempering hardness of blank
For HRC28-32.
Step 2：Forging blank after heat treatment is subjected to appearance and size mechanical processing, first roughing, then is finished；Che Duan
Face and outer circle；It is worked into process.
Step 3：It is molded with Emery grains emery wheel face grinding tooth.Using as shown in Figure 4 with transmission shaft end surface tooth terminal pad phase
Accord with the white fused alumina of tooth form（WA）Forming grinding wheel, on lathe cutter saddle, with dial gauge centering, it is desirable that wheel face and machine tool
Face is vertical；Then emery wheel is fixed, emery wheel is front and rear to be fed, and direction is constant；Transmission shaft connection plate is mounted on lathe table top rotary disk
Upper fixation must not move；Emery wheel primary feed；Complete the grinding in a direction；Rotary disk rotates 70 °, feeds again；2 times
Whole process, about 3 minutes time can be completed in feed.
Step 4：It bores, two earholes-subdrilling fabrication hole shown in boring Fig. 1, then bore hole, cut both ends spring catch collar aperture.
Step 5：Four hole of drill end.Bore four bolt fixing holes, and four angle of spot hole of ream.
Wherein, white fused alumina described in step 3（WA）Forming grinding wheel hardness 2200-2300HV, granularity 36-40, emery wheel machined surface
