Description

Technical Field

[0001] This utility model belongs to the field of crankshaft machining technology, and in particular relates to a workpiece flipping mechanism for crankshaft machining. Background Technology

[0002] The crankshaft is the most important component in an engine. It bears the force transmitted from the connecting rod and converts it into torque, which is then output through the crankshaft to drive other accessories on the engine. The crankshaft is subjected to the combined effects of centrifugal force from the rotating mass, periodically changing gas inertial force, and reciprocating inertial force, resulting in bending and torsional loads on the crankshaft.

[0003] Chinese patent CN221716409U discloses an automatic crankshaft turning device for crankshaft machining. The device includes: a worktable with two sliding grooves on its upper surface. A support frame is slidably connected inside the sliding grooves. Grooves are provided on both sides of the upper surface of the worktable. A first motor is fixedly connected to one side of each groove and to both sides of the worktable. A lead screw is fixedly connected to the output end of the first motor. A sliding block is sleeved on the outer side of the lead screw. A cylinder is fixedly connected above the sliding block. A support block is fixedly connected to the output end of the cylinder. A second motor is fixedly connected to the side of the support block that is away from each other. A rotating shaft is fixedly connected to the output end of the second motor. A limit device is provided at the end of the rotating shaft away from the second motor. A support plate is fixedly connected to one side of the support block. By setting up the sliding block, support block, and limit device, it is convenient to fix the crankshaft according to its diameter and to turn the fixed crankshaft, improving the stability of the crankshaft during turning and preventing displacement during machining, thus significantly improving the subsequent machining efficiency of the crankshaft.

[0004] However, existing technology can only install and process crankshafts manually before removing them, which is not highly automated. It is also quite troublesome to handle larger crankshafts. Therefore, it is necessary to design a workpiece flipping mechanism for crankshaft processing. Utility Model Content

Figures 1 to 5 As shown: the threaded rod 17 passes through the middle of the interior of the lifting plate 13, and lifting rods 15 are fixedly connected to both sides of the lifting plate 13.

[0032] In this embodiment, the lifting plate 13 is restricted to vertical movement inside the conveying box 1 by the slot 14 and the lifting rod 15.

[0035] In a further preferred embodiment of this utility model, the pressure plate 20 and the anti-slip pad 21 are both located on both sides inside the conveyor box 1 and are arranged in a mirror image. The anti-slip pads 21 on both sides are arranged opposite to each other, and the pressure plate 20 can be adapted to slide and insert into the inside of the receiving recess 6.

[0036] In this embodiment, the anti-slip pad 21 can prevent the crankshaft from slipping.

[0037] In a further preferred embodiment of the present invention, the top of the conveying box 1 is connected to the outside, and a tilting discharge mechanism is provided on one side of the conveying box 1.

[0038] In a further preferred embodiment of the present invention, the tilting discharge mechanism includes a tilting door 11 and a pneumatic telescopic rod 12.

The processed crankshaft naturally falls into the lower part of the conveyor box 1. The extending pneumatic telescopic rod 1 12 is activated to extend the flip door 11, which is then flipped open to facilitate the output of the crankshaft components input to the lower part of the conveyor box 1.
