Abstract

The invention discloses a special automatic grinding machine capable of loading and unloading automatically for crankshaft processing. The special automatic grinding machine comprises a rack, a clamping part, a grinding part, a power distribution box and a loading-unloading mechanism, wherein the clamping part comprises a first main shaft, a first drive motor, a main shaft tip end, a tail base anda tail base tip end; the grinding part comprises a grinding wheel, a second main shaft and a second drive motor; a crankshaft position measuring head is arranged at one side of the grinding wheel; aPLC controller is arranged in the power distribution box; the loading-unloading mechanism comprises a transmission frame, a loading mechanism and an unloading mechanism, a loading conveyor belt, an unloading conveyor belt and a supporting beam; the loading mechanism comprises a loading clamping jaw, a loading clamping air cylinder and a loading lifting air cylinder; the unloading mechanism comprises an unloading clamping jaw, an unloading clamping air cylinder and an unloading lifting air cylinder; and a crankshaft position measuring head, the first drive motor, the second drive motor, the loading mechanism and the unloading mechanism are connected with the PLC controller. The special automatic grinding machine is high in degree of automation, is high in grinding efficiency, reduces laborpower, reduces cost, is stable and reliable in clamping, and is high in loading and unloading efficiency.

Description

technical field [0001] The invention belongs to the field of automatic mechanical processing, and in particular relates to a special automatic grinding machine for crankshaft processing capable of automatic loading and unloading and a processing method thereof. Background technique [0002] The crankshaft structure is relatively specific, including the main journal, crank, connecting rod journal and some assembly holes. Therefore, it is difficult to clamp and grind during processing. At present, the clamping parts of ordinary crankshaft grinding machines have high stability of crankshaft clamping The rotation of the crankshaft is not flexible enough, and the stability of the clamping that can drive the crankshaft to rotate cannot be guaranteed. Moreover, the degree of automation of the grinding machine is low, and it is difficult to guarantee the clamping position of the crankshaft and the degree of grinding of the crankshaft, which not only affects the grinding efficiency, b...

[0002] The crankshaft structure is relatively specific, including the main journal, crank, connecting rod journal and some assembly holes. Therefore, it is difficult to clamp and grind during processing. At present, the clamping parts of ordinary crankshaft grinding machines have high stability of crankshaft clamping The rotation of the crankshaft is not flexible enough, and the stability of the clamping that can drive the crankshaft to rotate cannot be guaranteed. Moreover, the degree of automation of the grinding machine is low, and it is difficult to guarantee the clamping position of the crankshaft and the degree of grinding of the crankshaft, which not only affects the grinding efficiency, but also It will also affect the product quality;

[0003] Moreover, ordinary crankshaft grinding machines are mostly loaded and unloaded by hand. The labor intensity of workers is high, the degree of automation is low, and the efficiency of loading and unloading and clamping is low; while some automatic loading mechanisms are generally loaded separately and need to be done manually. Unloading, automatic unloading is not possible, and the efficiency of loading and unloading is still not guaranteed
