The quick-change connector 6 is connected with the other end of the articulated shaft with arm 5 through an articulated ball bearing.
The beneficial effects of the utility model are that, the supplementary axle housing assembly car process processing of truck axle housing assembly processing rigidity counter weight location auxiliary vehicle utensil, the clamping is convenient, and the adjustment is simple, and it has prepositioning with axle housing lute face, through the rotatory 90 quick-witted steps down of eave tile clamp plate, hoists the lathe, and the both ends are top in advance, and quick-operation joint impresses in the round pin, quick-operation joint built-in spring top pearl and the quick locking of cooperation of round pin. Thereby reach axle housing assembly, truck axle housing assembly processing rigidity counter weight location auxiliary turning utensil, lathe drive shaft and link as an organic wholely, rigid turning when guaranteeing axle housing assembly car flange terminal surface, tang, simple structure, convenient to use, powerful to unloading time in the effectual saving reduces intensity of labour.
Drawings
FIG. 1 is a schematic structural view of a tooling for machining an axle housing assembly of a medium and heavy truck according to the present invention;
FIG. 2 is a left side view of FIG. 1;
figure 3 is adopting the utility model discloses the axle housing assembly part map of processing.
Detailed Description
The technical solution of the present invention will be further described in detail with reference to the drawings.
As shown in figure 1 and figure 2, the utility model relates to a well heavy truck axle housing assembly processing frock includes the automobile body 1, eave tile clamp plate 2, rings 3, pivot pole 4, takes arm joint axle 5, quick change coupler 6. The surface of the vehicle body 1 is provided with a positioning boss. 2 eave tile clamp plate 2 rotates through 2 bolts and the car body 1 respectively and is connected, and 2 eave tile clamp plate 2 along car specific diagonal distribution, and the eave tile of eave tile clamp plate 2 is located car specific location boss place plane one side. One end of the axle pin rod 4 is fixed on one end of the vehicle body. The lifting ring 3 is fixed on the other end of the shaft pin rod 4. One end of the articulated shaft with arm 5 is sleeved on the periphery of the middle part of the shaft pin rod 4, and an articulated ball bearing is arranged between the articulated shaft with arm 5 and the joint surface of the periphery of the middle part of the shaft pin rod 4. The quick-change connector 6 is connected with the other end of the articulated shaft with arm 5 through an articulated ball bearing.
The processing tool of the axle housing assembly is prepositioned with an axle housing assembly lute surface and an inner strong opening, and is connected with the inner cavity wall of an axle housing assembly bridge through selectively mounting a 90-degree hook head pressing plate 2 and is screwed tightly. The axle housing assembly is rigidly connected with the truck axle housing assembly processing rigid counterweight positioning auxiliary vehicle tool. A lathe is arranged on a bracket by hoisting an axle housing assembly through a lifting ring 3, when the bracket runs to a machining position, two centers run to support parts, one end of a knuckle bearing 5 with an arm on the lathe body is provided with a quick-change connector 6 which is arranged in an upper pin of the end face of a main shaft, and the quick-change connector 6 is quickly locked through the matching of a top bead of a built-in spring and the pin. Therefore, the axle housing assembly and the truck axle housing assembly are integrally connected with each other through the rigid counterweight positioning auxiliary turning tool and the machine tool driving shaft, and the machine tool can be started. And after the machining is finished, the quick-change connector is pulled out, the two centers are loosened, the bracket returns, and the wire is hoisted and taken off. The whole processing ensures that the turning flange end face and the spigot excircle of the axle housing assembly are rigidly turned, and the jumping and coaxiality of the flange end face and the spigot excircle of the axle housing assembly are ensured. And verification shows that the final processing result is that the end face run-out is less than 0.05 mm, and the coaxiality of the outer circle run-out of the spigot to the A, B standard is within 0.2 mm. The utility model is effective and practical.
The end face of a flange of an axle housing assembly and the outer circle of a spigot are machined into precisely machined parts, the requirement of a product drawing is high, as shown in figure 2, the end face runout is required to be 0.04mm, the coaxiality of the outer circle of the spigot to an A, B standard is 0.2mm, the coaxiality to a single-head standard is 0.1mm, the current technological means is simple and crude, the best result of machining is that the end face runout is 0.08-0.1mm, and the coaxiality to a A, B standard is about 0.3 mm.
The utility model discloses an add auxiliary vehicle utensil class device of process at the machine, be the pivot of connecting part and lathe, at first, link into an integrated entity through this device quick clamping hook and axle housing assembly. Secondly, this process uses the middle drive double-end lathe, and the middle drive package of lathe middle part oil fixation hoists the part through the hoisting ring on this device, avoids producing the interference with the drive package when hoist and mount. Thirdly, when the quick clamping hook of the device is connected with the axle housing assembly into a whole to clamp the machine tool, the quick return joint on the device is used for quickly and rigidly connecting the quick return joint with the machine tool driving package, so that the axle housing assembly, the auxiliary turning tool device and the driving package are integrated when the driving machining is ensured, and the minimum eccentricity of the axial rotation of the whole axle housing assembly is ensured
The process comprises the following steps: and (3) placing the auxiliary turning tool device on the large end face of the lute hole of the part, rotating the two hook-shaped pressing plates for a certain angle, and finishing the installation process of the auxiliary turning tool device and the part. A workpiece is hoisted and placed on a bracket, when the bracket runs to a machining position, two centers run to support the part, one end (the end provided with a quick-change connector) of a knuckle bearing on a lathe body is arranged on the end surface of a main shaft, and then the lathe can be started. And after the machining is finished, the quick-change connector is pulled out, the two centers are loosened, the bracket returns, and the wire is hoisted and taken off.
