When the crankshaft to be produced is detected, the second magnetic clamp is installed on the first electric slide block 53 to clamp the auxiliary spindle hydraulic clamp 17 and the hydraulic clamp 19, then the first magnetic clamps installed on the auxiliary spindle hydraulic clamp 17 and the hydraulic clamp 19 are used for releasing the fixation of the main spindle 5 and the auxiliary spindle 16, then the first electric slide block 53 is started to enable the first electric slide block 53 to move in the first electric slide rail 52, so that the machined crankshaft is driven to move towards the side of the limit sleeve 55 and the detection cylinder 60, when the crankshaft is on the same horizontal line with the limit sleeve 55 and the detection cylinder 60, the power switches of the first electric push rod 54 and the second electric push rod 56 are started to enable the first electric push rod 54 and the second electric push rod 56 to move towards the side close to the crankshaft, and then the electric tube switch of the second magnetic clamp is disconnected and the detection cylinder 60 is sleeved outside the crankshaft.

When the detecting cylinder 60 is sleeved outside the crankshaft, the marking assembly 70 is moved along the track of the standard groove 62 through the second electric sliding block in the second electric sliding rail 61 arranged on the detecting cylinder 60 and the damper arranged at one end of the second electric sliding block, wherein the track of the standard groove 62 is in a shape corresponding to the curvature of the crankshaft standard part.

Because the shape and the direction of the crankshaft are different, a reference point needs to be found on the crankshaft when the detection is performed, so that the initial starting points of the crankshafts of the plurality of marking assemblies 70 arranged in the detection cylinder 60 are matched, at this time, the electromagnet 74 generates a certain repulsive force to the magnetic block 75 by starting the power switch of the electromagnet 74, so that the magnetic block 75 can drive the release assembly 80 to the limit, and the power switch of the second electric slider can drive the marking block 71 to rotate.

When the curvature of the crankshaft is normal or within an error range, the marking ball 88 on the release block 81 is made to slide in abutment with the crankshaft as the marking block 71 rotates, so that the marking of the crankshaft is achieved by the marking ball 88.

When the crankshaft is protruded in the manufacturing process, the curvature corresponding to the area is larger, when the protruded area of the crankshaft is in contact with the marking ball 88, a certain extrusion force is generated on the marking ball 88, so that the marking ball 88 acts on the sealing ball 87, the damping extrusion rod 83 is arranged in the extrusion groove 82, the elastic force of the damping extrusion rod 83 is larger than that of the extrusion spring 85, the sealing ball 87 is propped away from the state propped against the inner wall of the extrusion groove 82, meanwhile, the extrusion force on the sealing pad 84 is exerted by the damping extrusion rod 83, the marking liquid 86 arranged in the extrusion groove 82 is in an extrusion state, and when the sealing ball 87 is propped away, the marking liquid 86 enters the lower half area of the sealing ball 87 under the action of the pressure, and a sealing sleeve is arranged at the outer end of the sealing ball 87. 90, so that the marking liquid 86 does not flow out from the marking ball 88, and the marking hole is provided with a one-way valve, and the marking liquid 86 does not flow out even when the marking liquid 86 is not under the action of pressure.

When the marking liquid 86 is extruded and flows out, the marking liquid flows out from the marking holes formed on the release block 81, is sprayed on the marked area of the marking ball 88 and covers the marked area, the marking liquid 86 is made of water-based dye, is easy to dry and has different colors from the marked area of the marking ball 88, so that the marked area of the marking ball 88 is distinguished, the area is provided with bulges, and the curvature is large.

When there is a recess in the crankshaft, this indicates that the area has a small curvature, the marker ball 88 cannot contact it, and no marker is present there.

The color camera 76 follows the movement and recognizes and records the color of the movement, so that the overall quality condition of the crankshaft can be recorded, and the subsequent analysis problem generation and secondary processing measures are facilitated.

The mode is aimed at the situation that the curvature requirement is strict during detection, the implementation cost of the component is low, convenience and quickness are realized, when the crankshaft is detected with higher precision, the structure related to the mark can be replaced by a rolling ball and a pressure sensor, the judgment of the pressure magnitude captured in real time by rolling at the outer periphery of the crankshaft is facilitated, only the data of the standard crankshaft recorded by a comparison experiment are needed, the precision is high during detection, the cost is relatively high, and a specific detection mode can be selected according to the actual requirement.

Working principle:

The crankshaft is first placed on the small slide 3 of the bed assembly and secured by the bolted upper platen 12. The fixing mode ensures that the crankshaft is stable in the whole machining process and prevents movement caused by machine tool vibration or machining force. A spindle servo motor 24 in the spindle box assembly is started to drive the spindle 5 to rotate through a spindle pulley 6 and a spindle speed reducer 23. This step is a rough machining stage, which is mainly used to remove a large amount of material from the surface of the crankshaft, and lays a foundation for subsequent finishing. The cutter head main motor 11 in the cutter head driving assembly is started, power is transmitted to the cutter head reduction gearbox 7 through the synchronizing shaft 8, and the outer milling cutter 9 is driven to rotate at a high speed. The outer milling cutter disc carries out finish machining on the crankshaft, and high-precision surface treatment is realized by precisely controlling the cutting depth and the speed.

After the crankshaft is machined, the crankshaft needs to be detected, and the crankshaft is fixed and moved to a detection position by a second magnetic clamp mounted on the first electric slider 53. In the inspection position, the crankshaft is surrounded by an inspection cylinder 60, in which a marker assembly 70 is mounted that is movable along a predetermined trajectory. The marker assembly is activated by the electromagnet 74, scanned according to the shape of the crankshaft, and the curvature is identified by the contact of the marker ball 88 with the crankshaft. If a protrusion is present, the marking ball will press against the sealing ball 87, causing the marking fluid 86 to be squeezed out and marked on the crankshaft. The entire process is recorded by the color camera 76 for analysis and subsequent processing. Such a system may be replaced with a higher precision rolling ball and pressure sensor system as needed to address the more stringent curvature detection requirements.
