Problems solved by technology

Although this method can more intuitively reflect the manufacturing and assembly accuracy of the eccentric tooling, it is time-consuming and laborious to verify the accuracy of the tooling by trial-cutting the crankshaft sample, and the cycle is long, and there is a phenomenon that the crankshaft sample is scrapped after the trial cutting ,high cost

Embodiment

[0019] Lathe processing of heavy crankshaft pins, such as Figure 1-Figure 2 As shown, eccentric tooling is used for clamping, and the eccentric tooling includes positioning pin 2, gland 3, prismatic positioning pin 4, clamping pot 5, clamping ring 6, worm 7, balance weight 8 and trapezoidal screw 9, lathe The machine tool chuck 1 is provided at the head and the end of the bed, and the eccentric tooling is fixed on the inner surface of the machine tool chuck. It is required that the positioning blocks in the two clamping tanks at the head and the end of the bed have good coaxiality, and when processing the crankshaft, the indexing of the tooling is required to be accurate, The rotation synchronization is good. In order to meet the above requirements, the present invention provides a detection method of the eccentric tooling of the machine tool, which detects various precisions of the eccentric tooling of the machine tool.

Abstract

The invention discloses a detection method for an eccentric tool of a machine tool. The coaxiality of eccentric tool positioning blocks, the running depth of parallelism of stroke guide rails and therotating synchronism of a machine head and a tailstock are detected by adopting marble square boxes, a special detection bar for the machine tool and a dial indicator. Various precisions of the eccentric tool can be detected by adopting the simple device, so that the detection method is simple, easy to operate, high in detecting accuracy and high in stability.

Description

technical field [0001] The invention belongs to the technical field of eccentric tooling detection for processing machine tools, and in particular relates to a detection method for eccentric tooling for processing heavy crankshaft connecting rod necks on lathes and grinders. Background technique [0002] The eccentric tooling of the machine tool is a tooling fixture used for machining the outer circle of the crankshaft connecting rod neck, the fillet of the connecting rod neck, the opening of the connecting rod neck and the outer circle of the arm. The tooling directly affects the quality of the processed crankshaft connecting rod neck, so It is required that the two positioning blocks in the clamping tank at the head and the end of the bed have good coaxiality, and when machining the crankshaft, it is required that the indexing of the tooling is accurate and the rotation synchronization is good. [0003] At present, major domestic machine tool manufacturers do not have any ...
