Description

Technical Field

[0001] The present invention relates to the technical field of multi-station crankshaft processing, and in particular to an intelligent crankshaft processing machine tool. Background Art

[0002] The crankshaft is the most important part of the engine. It bears the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the combined effects of the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsion loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, work evenly and have good balance.

[0003] One or more transmission gears are installed at both ends of the crankshaft to achieve multi-structure linkage.

[0004] In the prior art, there is a crankshaft timing gear quick assembly device with Chinese patent number: CN204545868U, which includes a crankshaft support positioning mechanism and a press-fitting mechanism. The crankshaft support positioning mechanism includes a V-shaped block, a positioning seat, a positioning column, and a pressing cylinder. The main journals at both ends of the crankshaft are placed on the V-shaped block respectively, and the first connecting rod journal of the crankshaft is placed on the positioning seat. The side is pressed and positioned by the positioning column: the pressing cylinder. The pressing mechanism includes a thrust cylinder, a sleeve, a mandrel, a connecting shaft, and a compression spring. The mandrel, the connecting shaft, and the compression spring are installed in the sleeve, wherein the front end of the mandrel extends out of the sleeve, and the front and middle parts of the mandrel are respectively provided with keyways, and the front keyway is equipped with a flat key that matches the keyway of the timing gear. During assembly, the timing gear keyway is aligned with the flat key and placed on the mandrel, and the thrust cylinder is ventilated to drive the piston rod forward, and the sleeve and mandrel that move forward can quickly press the timing gear into the front end journal of the crankshaft. The structure is reasonable, the manufacture is easy, the assembly is simple, and the timing gear can be quickly assembled.

[0005] Although the above scheme has the above advantages, the disadvantage of the above scheme is that only a single gear can be installed at a time. When assembling a multi-gear crankshaft, the above operation needs to be repeated continuously to achieve the installation of multiple gears, which wastes time. In addition, manual adjustment is required when the gears are inserted to ensure that the gear slots correspond to the protrusions of the crankshaft, which is time-consuming and labor-intensive. In addition, during installation, scratches will appear on the installation path of the gears on the crankshaft due to friction. In addition, the above technical scheme requires high precision to achieve docking, but it is easy to cause the problem of docking failure due to slight misalignment. Summary of the invention

[0068] Hydraulic cylinder 1 23, hydraulic cylinder 2 24, hydraulic cylinder 3 52, hydraulic cylinder 4 62 and push rod motor 67 are all externally connected to the oil supplier. A controller is fixed on one side of the workbench 1. The controller is electrically connected to hydraulic cylinder 1 23, hydraulic cylinder 2 24, hydraulic cylinder 3 52, hydraulic cylinder 4 62, hydraulic cylinder 5 64, push rod motor 67, heating plate 617, air supply pump 4, oil supplier, motor 1 26 and motor 2 611.

[0069] Working principle:

[0070] The controller starts the rodless cylinder 32 to drive the mounting seat 33 to move. The movement of the mounting seat 33 drives the top structure and the crankshaft to move to the bottom of the mobile slotting machine 22. The hydraulic cylinder 24 is started to drive the mounting plate 25 and the motor 1 26 to move. The motor 1 26 approaches the two ends of the crankshaft and clamps the two ends of the crankshaft through a pair of clamping shafts. Then, the hydraulic cylinder 1 23 is started to push the hydraulic cylinder 24, the mounting plate 25, the motor 1 26, the clamping shaft 1 and the clamped crankshaft to move up and away from the mounting seat 33. The motor 1 26 is started to drive the crankshaft to rotate and then the crankshaft is slotted by the mobile slotting machine 22.

[0071] While the crankshaft is being processed, the controller controls the hydraulic cylinder four 62 to push or pull the U-shaped plate 618, the connecting rod group 619, the hollow mounting plate 620 and the structure installed on one side of the hollow mounting plate 620 according to the installation data of the crankshaft gear. Pushing will reduce the volume of the gear quantity adjustment block 623 located in the gear placement tube 69, that is, expand the internal space of the gear placement tube 69. When the space becomes larger, the number of gears that can be placed increases. The adjustment of the space matches the number of crankshaft mounted gears. On the contrary, when the space becomes smaller, the number of gears placed in the gear placement tube 69 is small. After the space is adjusted, the multiple gears that need to be installed on the outside of one end of the crankshaft are placed in the gear placement tube 69 in sequence according to the installation direction. The gears placed first are tightly attached to the gear quantity adjustment block 623, and the gears placed later are fitted with the gears placed first. When the gears are placed, they are sleeved on the outside of the clamping shaft two 53. The position of a group of hydraulic cylinders five 64 is located in the middle of a gear, and the two correspond to each other. The position of a gear correction clamping member group corresponds to the position of a gear.

[0072] After being inserted, the controller starts the oil supply and hydraulic cylinder five 64. The oil supply supplies oil to the middle group of hydraulic cylinders five 64 through the oil inlet end, and then the oil flows into the other groups of hydraulic cylinders five 64. After the oil enters the hydraulic cylinder five 64, it will push the piston plate to extend to contact and support the inner wall of the gear. The gear is corrected so that the center line of the gear coincides with the center line of the gear placement tube 69. The oil pressure sensor obtains the pressure of the oil supply. When the pressure reaches the standard, it is considered that multiple hydraulic cylinders five 64 have supported the corresponding gear. Because the inner diameters of multiple gears are not necessarily the same, it is necessary to supply oil by connecting multiple hydraulic cylinders five 64. When the extended length of each hydraulic cylinder five 64 is the same as the inner diameter of the corresponding gear, the piston plate cannot be extended, and then the oil supply is difficult to enter, and the oil will enter other gears that need When the oil of all the hydraulic cylinders 64 is difficult to enter, the oil pressure will increase. The increase in oil pressure means that the center lines of multiple gears and the gear placement tube 69 have been coincided. Then, according to the number of gears, the corresponding push rod motor 67 is controlled to push the arc plate 68 close to the gears. Because the outer diameters of the gears are different, the moving distances of the arc plate 68 are different. When the arc plate 68 contacts the corresponding gear, the pressure detector transmits the pressure to the controller, and then the controller turns off the push rod motor 67 to stop the movement of the arc plate 68. After all the gears are clamped externally, the controller controls the hydraulic cylinder 64 to retract the piston plate to release the support for the inside of the gear, and then starts the heating plate 617 to heat the inner wall of the gear to increase the inner diameter of the gear for easy insertion.

[0073] The crankshaft after the slotting process is moved down again and installed on the mounting seat 33, and the clamping of the clamping shaft 1 on it is released, and the magnet 38 attracts the bottom of the crankshaft to make the crankshaft sink to the bottom, and then the rodless cylinder 32 is controlled to move the mounting seat 33 and the crankshaft to between the two clamping shafts 2 53, and then the hydraulic cylinder 3 52 is controlled to push the clamping shaft 2 53 and other structures to move, so that the two clamping shafts 2 53 contact with both ends of the crankshaft to clamp the two ends of the crankshaft;

[0074] The controller starts hydraulic cylinder 4 62 to push U-shaped plate 618, connecting rod group 619 and hollow mounting plate 620 to move, and hollow mounting plate 620 pushes gear placement tube 69 and the gear inside to move. Because the two ends of the crankshaft are composed of multiple shafts with different diameters, the diameter size increases from small to large from the edge, and the gears placed in the gear placement tube 69 are installed according to the installation order of the shafts, so the inner diameters of the multiple gears in the gear placement tube 69 are from small to large from the inside to the outside, so when multiple gears are inserted together, the innermost gear with the smallest diameter will match the diameter of the outermost section of the crankshaft, and the diameters of the other gears are larger than the crankshaft, so when the innermost gear in the gear placement tube 69 is installed in this position, the larger diameters of the other gears will not affect it. During installation, when the slot of the inner diameter of the gear is docked with the protrusion of the crankshaft, the hydraulic cylinder four 62 is started to apply pressure to the gear inside the gear placement tube 69, and then the motor two 611 is started to drive the gear two 612 to rotate, and the gear two 612 drives the gear one 610 and the gear placement tube 69 to rotate, and the gear placement tube 69 drives the internal gear to rotate through the gear correction clamping member group, and then the slot of the inner diameter of the gear is stuck with the protrusion of the crankshaft. During the docking process, the pressure sensor obtains pressure. When the docking is completed, the pressure of the pressure sensor becomes smaller, and then the gear is continued to be pushed to move so that it is completely stuck, and then the push rod motor 67 is started to shrink the arc plate 68, and the hydraulic cylinder four 62 continues to push the other gears to move, so that the other gears are also installed in the corresponding positions in turn, and all the arc plates 68 are reset;

[0075] Continue to rotate the gear placement cylinder 69, the gear placement cylinder 69 drives the air supply pipe 615, the annular gas chamber 2 614 and the air outlet nozzle 616 to rotate, and then the hydraulic cylinder 4 62 drives the gear placement cylinder 69 to move back and forth, and then control the air supply pump 4 to supply air to the annular gas chamber 1 613. The annular gas chamber 1 613 is connected with the annular gas chamber 2 614, so the gas enters the annular gas chamber 2 614 and enters the air outlet nozzle 616 through the air supply pipe 615, and then is ejected. The gas rotates and moves to contact the gears and the crankshaft, cooling the gears in all directions, causing them to shrink and fit tightly with the crankshaft. The installation is completed, and then the crankshaft is removed to complete the processing.
