Therefore, an online dynamic balancing testing device for crankshafts is proposed to facilitate quick and convenient assembly and testing after adjusting the fixing device to clamp the crankshafts of different lengths. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an online crankshaft dynamic balance testing device, which facilitates quick and convenient assembly and testing after adjusting the fixing device to clamp crankshafts of different lengths.

[0005] The technical solution adopted by this utility model to solve its technical problem is a crankshaft dynamic balance online detection device, including a base, a support plate A, a support plate B and a crankshaft body. The support plate A and the support plate B are respectively provided on the top two sides of the base. The support plate A is respectively provided on one side of the support plate A and the connection column B. The top of the connection column B is tightened with a bolt. The top and bottom of the connection column A and the connection column B are respectively installed with bolts on one side of the support plate A.

[0006] The support plate B has mounting plates on both sides of its bottom. The top of the mounting plate has a pre-drilled hole through which a long bolt passes. The support plate A and the support plate B are connected by a crankshaft body via a rotating shaft.

[0007] Specifically, slots are provided at the top and bottom of one side of the connecting column A, and small cylinders are welded to the top and bottom of the slots respectively. The driving end of the small cylinders is connected to the arc-shaped limiting plate by bolts.

[0008] Specifically, a locking block is welded to the periphery of one side of the connecting column B, and an anti-slip ring is fitted in the recess of the locking block. The locking block is fixed between the arc-shaped limiting plates in the slot. The shaft passes through the reserved opening on the other side of the connecting column B. The tightening bolts pass through the reserved openings at the top of the connecting column B and the shaft, respectively. One end of the shaft is connected to the crankshaft body by a screw.

[0009] Specifically, a guide rail is provided at one end of the top of the base corresponding to the bottom of the support plate B.

[0010] Specifically, a motor is provided on one side of the support plate B, and the motor drive end is connected to the other end of the crankshaft body through a rotating shaft.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] To facilitate quick and convenient assembly and testing, the fixing device can be adjusted to clamp crankshafts of different lengths, allowing for easy assembly. Figure 1-4 As shown, the crankshaft dynamic balance online detection device of this utility model includes a base 1, a support plate A2, a support plate B14 and a crankshaft body 18. The support plate A2 and the support plate B14 are respectively provided on the top two sides of the base 1. The support plate A2 is respectively provided on one side and the connecting column A3 and the connecting column B7 are respectively provided on one side. The top of the connecting column B7 is tightened by a bolt 11. The top and bottom of the connecting column A3 and the connecting column B7 are respectively installed on the support plate A2 by bolts.

[0022] Mounting plates 16 are provided on both sides of the bottom of the support plate B14. Long bolts 17 pass through the pre-reserved openings at the top of the mounting plates 16. A crankshaft body 18 is provided between the support plate A2 and the support plate B14 via a rotating shaft.

[0023] In use, after sliding the distance between support plate A2 and support plate B14 along guide rail 13, rotate long bolt 17 downwards to close to the bottom of guide rail 13 to fix support plate B14. Connect one end of crankshaft body 18 of different lengths to shaft bolt, and insert shaft 12 of the other end into connecting column B7. Rotate and tighten bolt 11 to squeeze and fix the two. The bolt is connected between support plate A2 and support plate B14. Turn on motor 15 to drive crankshaft body 18 to rotate for easy balance testing.

[0024] The laser beam 19 shines horizontally onto the support plate B14, and the beam is located at the highest and lowest points of the crankshaft body 18. The staff can check whether the crankshaft body 18 blocks the beam when it rotates.

[0025] When the crankshaft body 18 is detected to be blocking light when it rotates, the small cylinder 5 drives the arc-shaped limit plate 6 to retract, remove the locking block 8 from between the arc-shaped limit plates 6, and then rotate the bolt to separate the shaft 12 from the connecting column B7. The staff can quickly disassemble the crankshaft body 18 and reprocess it.

[0026] After processing, the crankshaft body 18 can also be quickly installed, which is simple to operate and saves time.

[0027] For quick disassembly and assembly of the crankshaft, for example, such as Figure 1 , Figure 2 , Figure 3 As shown, this utility model also includes slots 4 on the top and bottom of one side of the connected column A3, and small cylinders 5 are welded to the top and bottom of the slots 4 respectively. The driving end of the small cylinders 5 is connected to the arc-shaped limiting plate 6 by bolts.

[0028] For example, such as Figure 1 , Figure 2 , Figure 3 As shown, this utility model also includes: a locking block 8 welded to the periphery of one side of the connecting column B7; an anti-slip ring 9 fitted in the recess of the locking block 8; the locking block 8 being secured between the arc-shaped limiting plates 6 in the slot 4; a shaft 12 passing through the reserved opening on the other side of the connecting column B7; and tightening bolts 11 passing through the reserved openings at the top of the connecting column B7 and the shaft 12, respectively; and one end of the shaft 12 being connected to the crankshaft body 18 by a screw.

[0029] During use, the small cylinder 5 is activated simultaneously, causing the arc-shaped limiting plate 6 to retract and the locking block 8 to be inserted between the arc-shaped limiting plates 6. This allows the arc-shaped limiting plate 6 to be locked in the recessed area around the locking block 8. The anti-slip ring 9 increases the friction between itself and the arc-shaped limiting plate 6, preventing the locking block 8 from shaking in the slot 4. Then, the shaft 12 is bolted to one end of the crankshaft body 18. The shaft 12 is inserted into the reserved opening of the connecting column B7, and the two are pressed and fixed by rotating and tightening the bolt 11.

[0030] For example, such as Figure 1 , Figure 4 As shown, the present invention also includes a guide rail 13 provided at the bottom of the support plate B14 at one end of the top of the base 1.

[0032] In use, after sliding the distance between support plate A2 and support plate B14 along guide rail 13, rotate long bolt 17 downwards to close to the bottom of guide rail 13 to fix support plate B14. Then, bolt crankshaft bodies 18 of different lengths between support plate A2 and support plate B14. Turn on motor 15 to drive crankshaft body 18 to rotate for easy balance testing.

[0033] In use, after sliding the distance between the support plate A2 and the support plate B14 along the guide rail 13, the long bolt 17 is rotated downwards to close to the bottom of the guide rail 13 to fix the support plate B14. One end of the crankshaft body 18 of different lengths is connected to the shaft bolt, and the shaft rod 12 of the other end is inserted into the connecting column B7. The bolt 11 is rotated and tightened to squeeze and fix the two. The bolt is connected between the support plate A2 and the support plate B14. The motor 15 is turned on to drive the crankshaft body 18 to rotate, which facilitates balance testing.

[0034] The laser beam 19 shines horizontally onto the support plate B14, and the beam is located at the highest and lowest points of the crankshaft body 18. The staff can check whether the crankshaft body 18 blocks the beam when it rotates.

[0035] When the crankshaft body 18 is detected to be blocking light when it rotates, the small cylinder 5 drives the arc-shaped limit plate 6 to retract, remove the locking block 8 from between the arc-shaped limit plates 6, and then rotate the bolt to separate the shaft 12 from the connecting column B7. The staff can quickly disassemble the crankshaft body 18 and reprocess it.
