Description

Technical Field

[0001] The utility model belongs to the technical field of crankshaft transfer devices, and in particular relates to a crankshaft transfer device. 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] Chinese patent announcement No. CN218661954U discloses a transfer device for crankshaft processing, which relates to the field of crankshaft processing equipment, including a mobile vehicle, a transfer box is arranged on the mobile vehicle, a plurality of groups of slide grooves are arranged in the transfer box, a placement box is slidably matched in the slide groove, a second placement groove and a plurality of first placement grooves are opened in the placement box, a tightening assembly is arranged in the second placement groove, and a rubber pad is arranged in the first placement groove; compared with the prior art, this device can store crankshafts of different sizes in multiple layers, a large number of crankshafts are placed and the crankshafts are stored separately, thereby avoiding the occurrence of collisions between crankshafts during transportation, and at the same time, the tightening assembly is used to clamp and tighten multiple crankshafts in a layer of placement box at a time, ensuring that the crankshaft will not move in the first placement groove during transportation, thereby further improving the placement stability of the crankshaft during transportation.

[0004] With respect to the above-mentioned related technologies, the inventors have found that there are at least the following problems in the technology: the transfer device can only transfer a limited number of crankshafts and cannot be adjusted according to the actual number, which results in the need for continuous back and forth transportation during transportation. At the same time, the placement box of the device is only used to fix crankshafts of the same size and cannot be used for crankshafts of different sizes. As a result, when transporting and fixing crankshafts of different sizes, the crankshafts shake and collide in the placement box. This has great limitations. For this reason, we provide a transfer device that can be adjusted according to the number of crankshafts and is convenient for fixing crankshafts of different sizes. Utility Model Content

[0005] The purpose of the utility model is to provide a crankshaft transfer device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crankshaft transfer device, including a cart, a fixed box is fixedly connected to the upper end of the cart, a movable box is detachably provided on the upper end of the fixed box, a number of the movable boxes are stacked and the movable boxes are detachably provided, a number of partitions are fixedly provided in the fixed box and the movable box, connecting grooves are provided on the upper surfaces of the fixed box and the movable box, a connecting rod that cooperates with the connecting grooves is fixedly connected to the lower end of the movable box, and a fixed rod is fixedly connected to one side of the cart.

The pull rod pushes the limit block to be inserted into the limit groove through the reset spring, thereby restricting the connecting block in the connecting groove to prevent the movable box from sliding out when the cart moves.

[0010] Optionally, compression springs are fixedly connected inside both sides of one end of the partition, and clamping plates are fixedly connected to the ends of the compression springs.

[0011] By adopting the above technical solution: placing the crankshaft between the two partitions, and placing one end of the crankshaft between the clamping plates, and pushing the clamping plates by compressing the spring, the crankshaft can be fixed.

[0012] Optionally, a rubber pad is fixedly connected to the surface of the clamping plate.

[0013] By adopting the above technical solution: when the splint fixes the crankshaft, the rubber pad fits against the end of the crankshaft, so that the splint fits more closely against the end of the crankshaft and prevents the crankshaft from sliding.

[0014] Optionally, a movable plate is movably arranged between every two of the partitions, a thrust spring is fixedly connected to the back of the movable plate, and the other end of the thrust spring is fixed to the inner wall surface of the fixed box or the movable box, and an anti-slip pad is fixedly connected to the surface of the movable plate.

[0015] By adopting the above technical solution: one end of the crankshaft is fixed by a clamp, and the other end is pushed by a thrust spring to move the movable plate toward the crankshaft, and then the crankshaft is pressed by the thrust spring, thereby ensuring the stability of the crankshaft between the partitions and avoiding sliding and collision of the crankshaft.

[0016] Optionally, sliders are fixedly connected to both sides of the movable plate, and the sliders are slidably arranged in slide grooves, and the slide grooves are opened on both sides of the partition.

[0017] By adopting the above technical solution: when the moving plate moves, the slider moves in the slide groove, and then the moving plate is limited by the slider to prevent the moving plate from deflecting.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

When in use, the crankshafts to be transported are placed in the fixed box and the movable box, and the fixed box and the movable box can be spliced ​​together, and then assembled according to the number of crankshafts. When the movable box is full of crankshafts, the connecting rod at the lower end of the movable box can be calibrated and docked with the connecting groove, and then the pull rod on one side of the fixed seat is pulled, and the pull rod drives the limit block to move, and then the movable box is pushed to make the connecting rod completely inserted into the connecting groove, and then the pull rod is released. While the pull rod is reset by the reset spring, the limit block is embedded in the limit groove, thereby limiting the connecting rod to the connecting groove, and then fixing the movable box. The movable boxes can be stacked and spliced ​​in this way, and then multiple crankshafts can be transported at the same time, so that it can be adjusted according to the actual number of crankshafts, reducing the limitations of the transport device.

[0020] 2. The utility model is provided with a partition, a slide groove, a compression spring, a clamp, a movable plate, a slider and a thrust spring. When placing a fixed crankshaft, one end of the crankshaft is placed against the clamp, and the clamp is pushed to move toward the center by the compression spring in the partition, and the rubber pad better fits the end of the crankshaft, so that one end of the crankshaft is fixed, and the other end is pushed to move the movable plate by the thrust spring, and pressure is applied to the other end of the crankshaft, thereby fixing the crankshaft in a fixed box or a movable box. This method is suitable for fixing crankshafts of different sizes. At the same time, the operation is simple and quick, and the stability of the crankshaft in the fixed box and the movable box is ensured. BRIEF DESCRIPTION OF THE DRAWINGS
