Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts processing, in particular to a motor vehicle engine crankshaft placing rack. Background Art
[0002] The crankshaft is the main rotating component of the engine. After the connecting rod is installed, it can convert the up and down reciprocating motion of the connecting rod into a circular rotating motion. The rotation of the crankshaft is the power source of the engine and also the source of power for the entire mechanical system in the engine.
[0003] There are strict requirements for various production equipment, transfer equipment, storage and transportation in the crankshaft production workshop. When the crankshaft is produced according to the production requirements, if it is worn or even scrapped due to stacking in transfer, it will undoubtedly increase the scrap rate of the product and greatly increase the production cost of the crankshaft. Utility Model Content
[0004] The utility model aims to solve the existing problems and provides a motor vehicle engine crankshaft placement rack.
[0005] The utility model is realized through the following technical scheme: a motor vehicle engine crankshaft placement rack, comprising a bottom frame, a bracket arranged below the bottom frame, a placement plate connected transversely and symmetrically throughout the length of the bottom frame, shelf grooves arranged at intervals on the placement plate, partition rods connected between the shelf grooves, supports vertically connected to the peripheral corners of the bottom frame, the tops of the supports are connected to support rods, and the outer sides of the placement plates are connected to the bottom frame via angle plates at intervals.
[0006] As a further improvement to the above scheme, the shelf groove is V-shaped, and the bottom of the shelf groove is provided with an arc bottom surface, the V-shaped shelf grooves are arranged on the placement plate at intervals, the depths of two adjacent V-shaped shelf grooves are different, and they match the end shafts of the crankshaft, the crankshaft is conveniently placed through the V-shaped shelf groove, and the arc bottom surface of the V-shaped shelf groove is used to match the end shaft of the crankshaft, so that the crankshaft is placed more stably.
[0007] As a further improvement to the above scheme, the end of the partition rod is connected to the vertical surface of the placement plate outside the partition groove, which is used to separate adjacent crankshafts to avoid collision between two adjacent crankshafts. At the same time, it is used to build a balance fan plate for the crankshaft to prevent the crankshaft from sinking and deforming.
[0008] As a further improvement to the above solution, a support plate is connected between the support and the bottom frame on two frame rods of the bottom frame to enhance the support strength of the support.
[0009] Compared with the prior art, the utility model has the following advantages: simple structure, reasonable design, novel and unique concept, symmetrically arranged shelf grooves on the placement plate are used to place crankshafts, and adjacent crankshafts are separated by partition rods to avoid collision between two adjacent crankshafts, and at the same time, a balancing fan plate for the crankshaft is used to prevent the crankshaft from concave deformation. In addition, two adjacent shelf grooves are used to match the two end shafts of the crankshaft respectively, so that the crankshaft is compactly placed on the placement plate, and the stacking of the placement racks facilitates transportation and storage.

[0015] The utility model is further described below in conjunction with the accompanying drawings.
[0016] like Figures 1 to 5 As shown in the figure, a motor vehicle engine crankshaft placement rack includes a base frame 1, a bracket 2 is arranged below the base frame 1, a placement plate 3 is connected horizontally and symmetrically in the base frame 1, shelf grooves 4 are arranged on the placement plate 3 at intervals, and partition rods 6 are connected between the shelf grooves 4. Supports 7 are vertically connected to the peripheral corners of the base frame 1, and the top of the support 7 is connected to the support rod 9. The outer side of the placement plate 3 is connected to the base frame 1 through an angle plate 5 at intervals.
[0017] As a further improvement to the above scheme, the shelf groove 4 is V-shaped, and the bottom of the shelf groove 4 is provided with an arc bottom surface, the V-shaped shelf groove 4 is arranged on the placement plate 3 at intervals, the depths of two adjacent V-shaped shelf grooves 4 are different, and they match the end shafts of the crankshaft 10, and the crankshaft 10 is conveniently placed through the V-shaped shelf groove 4, and the arc bottom surface of the V-shaped shelf groove 4 is used to match the end shaft of the crankshaft 10, so that the crankshaft 10 is placed more stably.
[0018] As a further improvement to the above scheme, the end of the partition rod 6 is connected to the vertical surface of the placement plate 3 outside the partition groove, which is used to separate adjacent crankshafts 10 to avoid collision between two adjacent crankshafts 10, and at the same time to build a balancing fan plate of the crankshaft 10 to prevent the crankshaft 10 from sinking and deforming.
[0019] As a further improvement to the above solution, a support plate 8 is connected between the support 7 and the bottom frame 1 on two frame rods of the bottom frame 1 to strengthen the support strength of the support 7 .
[0020] The working principle of a rack for placing crankshafts 10 of motor vehicle engines is as follows: the end shafts of matching crankshafts 10 are placed according to the coaxial V-shaped rack grooves 4 on the placement plates 3 on both sides, so that the two adjacent crankshafts 10 are placed upside down to achieve the purpose of compact placement of the crankshafts 10; at the same time, the balance fan plates of the two adjacent crankshafts 10 are respectively mounted on different positions of the partition rod 6 to avoid contact between the balance fan plates of the two adjacent crankshafts 10, and the top end of the support rod 9 at the corner of the bottom frame 1 is inserted into the lower end hole of the foot rod of the bracket 2 for stacking in layers to save placement space and increase transportation volume.
