Description

Technical Field

[0001] The utility model relates to the technical field of crankshafts, in particular to an adjustable crankshaft production, grinding and hoisting device. Background Art

[0002] The crankshaft is the most important component in the engine. It receives force from the connecting rod and converts it into torque, which is then output through the crankshaft to drive the engine's accessories. The crankshaft is subject to the combined effects of centrifugal force from the rotating mass, cyclically changing gas inertia, and reciprocating inertia, subjecting it to bending and torsional loads. Therefore, the crankshaft must possess sufficient strength and rigidity, a wear-resistant journal surface, uniform operation, and good balance.

[0003] In order to reduce the wear of the crankshaft during operation and ensure the smooth operation of the crankshaft, the crankshaft needs to be polished during the production process to avoid burrs on the surface affecting the use of the crankshaft. When the crankshaft is polished, a fixing device is usually required to position it.

[0004] After searching, it was found that in the patent publication number CN220131710U, a device for fine grinding and polishing of crankshaft production, it was proposed that "the device for fine grinding and polishing of crankshaft production can not only facilitate the workers to lift the crankshaft, but also facilitate the workers to fix crankshafts of different sizes, thereby greatly increasing the practicality of the equipment, not only making the crankshaft limit plate more stable, but also making the crankshaft more stable."

[0005] However, the above solution still has certain shortcomings in actual use. In the above solution, a winding roller is used to adjust the height of the crankshaft after clamping, but the lifting process using the winding roller and the steel cable is not stable enough, which greatly reduces the lifting stability.

[0022] See also Figure 1-4 The utility model discloses an adjustable crankshaft production grinding and hoisting device, including a processing table 1 and a crankshaft body 2. The top of the processing table 1 is provided with a driving device 4 and a fixed hoisting structure 3. The movable end of the driving device 4 is provided with a mobile hoisting structure 5. The mobile hoisting structure 5 and the fixed hoisting structure 3 are on the same horizontal line.

[0024] The driving device 4 includes an electric slide rail 401 , a movable end of which is fixedly mounted with an electric slider 402 , which is fixedly connected to the back side of the mobile hoisting structure 5 , and a guide wheel is provided at the bottom end of the mobile hoisting structure 5 .

[0025] The working principles of the electric slide rail 401 and the electric slider 402 have been described in detail in a SMT placement machine positioning device with patent publication number CN202322179404.9, and will not be expanded here.

[0026] The fixed hoisting structure 3 and the mobile hoisting structure 5 have the same structure. The mobile hoisting structure 5 includes a mounting frame 501. An electric push rod 502 is fixedly installed on the inner side of the mounting frame 501. The movable end of the electric push rod 502 is fixedly installed with a contact arc plate 504. The side end of the contact arc plate 504 is fixedly installed with a movable block 503. The bottom end of the movable block 503 overlaps the top of the mounting frame 501. The top of the movable block 503 is fixedly installed with a brake box 505.

[0027] The inner wall of the brake box 505 is rotatably connected to a rotating shaft 506 through a built-in motor, and a movable ring 507 is provided on the surface of the rotating shaft 506. The bottom end of the movable ring 507 is rotatably connected to a hinged rod 508, and the bottom end of the hinged rod 508 is hinged to a lifting plate 509. The bottom end of the lifting plate 509 is fixedly installed with a plug-in arc plate 510, and the plug-in arc plate 510 is located above the contact arc plate 504.

[0028] By setting up a fixed lifting structure 3, a driving device 4 and a mobile lifting structure 5, the driving device 4 can be used to drive the interval between the fixed lifting structure 3 and the mobile lifting structure 5 to be adjusted, so that the interval between the fixed lifting structure 3 and the mobile lifting structure 5 can be adaptively clamped according to the length of the crankshaft body 2, and the two sets of lifting structures can be fixed according to the diameter of the crankshaft body 2, and the crankshaft body 2 can be rotated after being fixed, so that the angle of the crankshaft can be adjusted according to the grinding requirements after being hoisted, which significantly improves the practicality of the grinding lifting device.

[0029] Specifically, a curved groove connected end to end is opened on the surface of the rotating shaft 506, and a plug-in rod is fixedly installed on the inner wall of the movable ring 507, and the plug-in rod is located inside the curved groove.

[0030] In this embodiment, since the surface of the rotating shaft 506 is provided with a curved groove connected at the end, and the interior of the movable ring 507 is fixedly connected with a plug-in rod, and the plug-in rod is located inside the curved groove, the rotating shaft 506 starts to drive the curved grooves connected at the beginning and the end to rotate, causing the relative position between the opening of the curved groove and the plug-in rod to change, causing the opening of the curved groove to drive the movable ring 507 to move in the axial direction through the plug-in rod.

[0031] Specifically, a ball bearing 512 is slidably connected to the inner side of the resisting arc plate 504 , and an arc-shaped transmission belt 511 is provided on the inner side of the plug-in arc plate 510 via a built-in power supply.

[0032] In this embodiment, when it is necessary to adjust the angle of the crankshaft body 2 after clamping, the arc transmission belt 511 is started by the built-in power supply, so that the arc transmission belt 511 starts to run and rotate on the inner side of the plug-in arc plate 510, prompting the arc transmission belt 511 to drive the crankshaft body 2 and the ball 512 on the inner side of the contact arc plate 504 to slide and connect through the transmission friction force, so that the crankshaft body 2 rotates between the plug-in arc plate 510 and the contact arc plate 504, so that the angle of the crankshaft body 2 after clamping is adjusted.

[0033] When in use, the staff can first place the equipment at the use location and turn on the power supply, and then adjust the distance between the fixed lifting structure 3 and the movable lifting structure 5 according to the length of the crankshaft body 2 to be lifted;

[0034] The electric slide rail 401 is turned on, so that the electric slide rail 401 drives the electric slider 402 to move, which in turn drives the movable hoisting structure 5 to slide horizontally on the workbench, so that the distance between the fixed hoisting structure 3 and the movable hoisting structure 5 can be adaptively adjusted according to the length of the crankshaft body 2;

[0035] Then, the crankshaft body 2 is placed between the fixed hoisting structure 3 and the mobile hoisting structure 5, and then the fixed hoisting structure 3 and the mobile hoisting structure 5 are opened;

[0036] The built-in motor inside the brake box 505 starts to drive the rotating shaft 506 to rotate. Since the surface of the rotating shaft 506 is provided with a curved groove connected at the end, and the internal part of the moving ring 507 is fixedly connected with a plug-in rod, and the plug-in rod is located inside the curved groove, the rotating shaft 506 starts to drive the curved groove connected at the head and tail to rotate, causing the relative position between the opening of the curved groove and the plug-in rod to change, causing the opening of the curved groove to drive the moving ring 507 to move in the axial direction through the plug-in rod, so that the moving ring 507 starts to drive the hinge rod 508 to adjust the angle, causing the hinge rod 508 to drive the lifting plate 509 to slide inside the brake box 505, causing the lifting plate 509 to drive the plug-in arc plate 510 to gradually descend, so that the plug-in arc plate 510 is finally inserted into the inside of the contact arc plate 504, causing the side end of the crankshaft body 2 to be clamped between the plug-in arc plate 510 and the contact arc plate 504, so that the crankshaft body 2 is clamped between the fixed lifting structure 3 and the movable lifting structure 5;

[0037] When the crankshaft body 2 after clamping needs to be hoisted, the electric push rod 502 inside the mounting frame 501 is started, so that the movable end of the electric push rod 502 drives the contact arc plate 504 to adjust the height, prompting the contact arc plate 504 to drive the clamped crankshaft body 2 to be hoisted;

[0038] When it is necessary to adjust the angle of the crankshaft body 2 after clamping, the arc transmission belt 511 is started by the built-in power supply, so that the arc transmission belt 511 starts to run and rotate on the inner side of the plug-in arc plate 510, prompting the arc transmission belt 511 to drive the crankshaft body 2 and the ball 512 on the inner side of the contact arc plate 504 to slide and connect through the transmission friction force, so that the crankshaft body 2 rotates between the plug-in arc plate 510 and the contact arc plate 504, so that the angle of the crankshaft body 2 after clamping is adjusted.

[0039] To sum up, the adjustable crankshaft production and grinding hoisting device is equipped with a fixed hoisting structure 3, a driving device 4 and a mobile hoisting structure 5. The driving device 4 can drive the interval between the fixed hoisting structure 3 and the mobile hoisting structure 5 to be adjusted, so that the interval between the fixed hoisting structure 3 and the mobile hoisting structure 5 can be adaptively clamped according to the length of the crankshaft body 2. The two sets of hoisting structures can be fixed according to the diameter of the crankshaft body 2, and the crankshaft body 2 can be rotated after being fixed, so that the angle of the crankshaft can be adjusted according to the grinding requirements after being hoisted, which significantly improves the practicality of the grinding hoisting device.
