Description

Technical Field

[0001] The utility model relates to the field of automobile production and processing, and in particular to a three-dimensional warehouse type fixture switching and storage system. Background Art

[0002] With the rapid development of the automobile industry, consumers' demand for diversified car styles is growing, which puts forward higher production flexibility requirements for automobile manufacturers. To meet this challenge, modern automobile production lines generally adopt a multi-model co-production mode to achieve alternating processing of different models on the same production line, thereby improving production efficiency and production line utilization. In this mode, the fixture switching and storage system, as a core component, plays a vital role.

[0003] The design of the fixture switching and storage system directly affects the efficiency and flexibility of the production line. The fixture switching and storage system developed by the applicant adopts a ground layout, that is, a series of ground storage locations are configured next to the production line, and each storage location stores special fixtures required for different models. When the production line needs to process a specific model, the corresponding fixture is called out from the storage location, transported to the processing location for assembly through a slide rail, and after processing, it is returned to the storage location along the original route for storage for the next use. However, the ground-layout fixture switching and storage system occupies a large area and is subject to the limitation of factory space, so the number of storage locations that can be configured is limited, which directly affects the processing capacity of the production line and the flexibility of vehicle model switching. Utility Model Content

[0004] The utility model aims to provide a three-dimensional storage type fixture switching and storage system to solve the problem that the existing fixture switching and storage system occupies a large area.

[0008] Preferably, as an improvement, ground storage locations are provided on both sides of the slide rail.

[0009] Preferably, as an improvement, two ground storage positions are respectively arranged on both sides of the slide rail along the axial direction, and a layer of aerial storage positions is arranged above the two ground storage positions away from the processing positions.

[0010] Preferably, as an improvement, the guide assembly includes a plurality of support guide wheels for supporting the bottom of the fixture and limiting wheels capable of rolling along the side of the fixture, and the support guide wheels and the limiting wheels are alternately arranged.

[0011] Preferably, as an improvement, the driving assembly on the slide rail is connected to an oiling assembly.

[0012] Preferably, as an improvement, the oiling assembly includes a gear shaft, the interior of the gear shaft is hollow to form an oil chamber, an oil seal is fixed on the top of the oil chamber, the oil seal is connected to the oil chamber, the oil seal is fixedly connected to the reducer, an oiling gear is rotatably connected to the gear shaft, the oiling gear is meshed with the other side of the power gear, the gear shaft is circumferentially provided with oil holes, the oil holes are connected to the oil chamber, an oil channel is provided in the oiling gear, one end of the oil channel extends to the interior of the oiling gear and can be connected to the oil hole, the other end of the oil channel extends to the tooth groove of the oiling gear, the oil seal is also connected to an oil pipe, the oil pipe extends to the outside of the tray and is connected to the oil hopper installed on the side of the tray.

[0013] The principles and beneficial effects of this scheme are:

[0014] 1. This solution sets up ground storage locations on both sides of the slide rails, and sets up aerial storage locations above the ground storage locations. Compared with setting up storage locations only on the ground, this solution effectively utilizes the aerial space, greatly improves the space utilization rate of the factory, and can arrange more storage locations to meet the processing of more car models, thereby improving processing flexibility and efficiency.

[0015] 2. This solution adopts a traction method that combines a traction hook and a traction wheel, which can not only realize the storage and unloading of the fixture in the ground storage, but also can easily realize the storage and unloading of the fixture in the aerial storage with the lifting pallet. Specifically, the storage and unloading of the fixture in the aerial storage is as follows: after the fixture is transported to the bottom of the lifting pallet, it is first towed to the ground storage by the traction mechanism of the ground storage for temporary storage. After the lifting pallet is lowered, the traction mechanism is used to push the fixture from the ground storage to the lifting pallet, and the fixture is raised to the aerial storage by the lifting pallet, and then towed to the aerial storage by the traction mechanism of the aerial storage. Compared with traction methods such as robots and traction carts, the traction mechanism of this solution has a simple structure and is easy to operate. It is integrated in the storage and does not take up a large space, further improving the space utilization rate of the factory building.

[0016] 3. The traction motor is driven to slide by the traction gear and rack. Compared with the electrode screw, the traction gear and rack have a simpler structure, lower processing difficulty, processing cost and maintenance cost. After the lifting pallet rises to the aerial storage location, the lifting pallet can be fixed by clamping the positioning block with the clamping cylinder to ensure the stability of the fixture in storage.

[0017] 4. Setting up the guide assembly can make it easier for the fixture to enter and exit the warehouse, reduce the resistance of the fixture entering and exiting the warehouse, thereby reducing the resistance of components such as the traction motor, traction gear and rack, which can effectively extend the service life of related components, thereby extending the service life of the equipment, reducing the frequency of equipment maintenance and replacement, and saving costs.

[0018] 5. The oiling component of the present solution is arranged next to the power gear. When the power gear rotates, it can drive the oiling gear meshing with it to rotate. The oil channel on the rotating oiling gear is connected with the oil hole on the gear shaft, so that the lubricating oil in the gear shaft flows along the oil channel to the tooth groove of the oiling gear, and the lubricating oil is applied to the power gear and the rack through the meshing action. In this way, the power gear and the rack are oiled during the sliding process of the pallet and the fixture. The oiling is convenient, and compared with the separate oiling after shutdown, it does not need to occupy the production time, and also saves the extra oiling process, thereby improving the processing efficiency.

[0035] Combination Figure 4 , Figure 5 and Figure 6 As shown, each storage location is equipped with a traction mechanism, which includes a traction motor 61, a traction hook 66, a guide assembly and a traction wheel 6. The traction wheel 6 is bolted to the left and right sides of the clamp 2 and can be hooked by the traction hook 66; the guide assembly includes a plurality of support guide wheels 67 for supporting the bottom of the clamp 2 and a limiting wheel 68 that can roll along the side of the clamp 2.

The above-mentioned guide assembly is also installed on the lifting pallet 4 and the pallet 7, and the guide assembly is also installed on the front and rear sides of the pallet 7 (lifting pallet 4). When the fixture 2 is installed on the pallet 7 (lifting pallet 4), it is mounted on the supporting guide wheel 67 of the guide assembly, and the fixture 2 is limited by the limiting wheels 68 on the front and rear sides. A pallet positioning cylinder 72 is bolted to the pallet 7, and the pallet positioning cylinder 72 is connected to the pallet positioning pin 73. Two positioning wheels 74 are rotatably installed on the slide rail 1, and a positioning space for inserting the pallet positioning pin 73 is formed between the two positioning wheels 74. Both positioning wheels 74 can be rotatably connected to the pallet positioning pin 73. The lifting tray 4 and the tray 7 are both bolted with clamp positioning cylinders. In this embodiment, there are two clamp positioning cylinders, which are installed on the diagonal lines of the tray 7 (lifting tray 4). The two clamp positioning cylinders are both connected with clamp positioning pins 70.

[0037] The tray 7 is bolted with a driving motor 71, which is also connected to the driving assembly, that is, the output shaft of the driving motor 71 is also connected to the reducer 62, which is also keyed to the power gear 69, and the slide rail 1 is also bolted with a rack 60, which is meshed with one side of the rack 60. The difference is that the driving assembly on the slide rail 1 is connected to an oiling assembly, which is combined with the Fig. 9 and Fig.10 As shown, the oiling assembly includes a gear shaft 84, which is hollow inside to form an oil chamber, an oil seal 80 is fixed on the top of the oil chamber, and the oil seal 80 is connected to the oil chamber, a mounting plate is bolted to the bottom of the reducer 62, and the oil seal 80 is bolted to the mounting plate, an oiling gear 8 is rotatably connected to the gear shaft 84, and the oiling gear 8 is meshed with the other side of the power gear 69, and an oil hole 83 is circumferentially opened on the gear shaft 84, and the oil hole 83 is connected to the oil chamber, an oil channel is opened in the oiling gear 8, one end of the oil channel extends to the inside of the oiling gear 8 and can be connected to the oil hole 83, and the other end of the oil channel extends to the tooth groove of the oiling gear 8, and the oil seal 80 is also connected to an oil pipe 82, and the oil pipe 82 extends to the outside of the tray 7 and is connected to an oil hopper 81 bolted to the side of the tray 7.

[0038] The working principle of this scheme is:

[0039] The fixture 2 is fixed on the pallet 7. The fixation of the fixture 2 is specifically as follows: after the fixture 2 is placed on the pallet 7, the fixture 2 is mounted on the support guide wheel 67, the limit wheel 68 limits the position of both sides of the fixture 2, and the fixture positioning cylinder drives the fixture positioning pin 70 to be inserted into the positioning hole on the fixture 2 to achieve the fixation of the fixture 2.

[0040] The fixture 2 is transported between the processing position 11 and the storage position by sliding the tray 7 along the slide rail 1, so as to realize the storage and switching of the fixture 2. Taking the arrival at the ground storage position 3 as an example, the motor and the reducer 62 drive the power gear 69 to rotate, and the power gear 69 rolls along the rack 60, driving the tray 7 to slide on the slide rail 1. When it arrives at the ground storage position 3, the traction motor 61 is located at the storage position entrance of the ground storage position 3 ( Figure 5 The traction hook 66 is located on the right side of the fixture 2. When the fixture 2 reaches the storage opening of the ground storage location 3, the traction wheel 6 on it can be directly inserted into the traction hook 66 from the front side to achieve the docking of the traction hook 66 and the traction wheel 6. After the traction hook 66 and the traction wheel 6 are docked, the traction motor 61 drives the traction gear to rotate, and the traction gear rolls along the rack 60 to the left end of the storage location 3, thereby driving the traction motor 61 to slide from the right end to the left end of the ground storage location 3, thereby pulling the fixture 2 into the ground storage location 3 to achieve the storage of the fixture 2. During the movement of the fixture 2 on the ground storage location 3, the fixture 2 is mounted on the support guide wheel 67 and the support guide wheel 67 is forced to rotate by friction, making it easier for the fixture 2 to enter the storage. During the storage process, the limit wheel 68 rolls along the side of the fixture 2 to limit and guide the fixture 2, thereby improving the storage stability of the fixture 2.

[0041] When the clamp 2 is out of the warehouse, the traction motor 61 drives the traction gear to rotate in the opposite direction, so that the traction gear rolls along the rack 60 from the left end to the right end of the rack 60, thereby driving the traction motor 61 to slide from the left end to the right end of the ground storage position 3, and then pushes the clamp 2 hooked on the traction hook 66 from the ground storage position 3 to the slide rail 1, completing the removal of the clamp 2 from the warehouse.

[0042] When the clamp 2 is transported to the aerial storage position 31, the pallet 7 now transports the clamp 2 to the bottom of the lifting pallet 4, and the clamp 2 is pulled to the ground storage position 3 for temporary storage by the traction mechanism on the ground storage position 3. Then, the lifting mechanism drives the lifting pallet 4 to descend to be flush with the ground storage position 3, and then the traction mechanism on the ground storage position 3 is used to push the clamp 2 onto the lifting pallet 4 and position it through the clamp positioning pin 70. Then, the lifting mechanism drives the lifting pallet 4 to rise to one side of the aerial storage position 31 and slightly higher than the aerial storage position 31 so that the traction hook 66 of the aerial storage position 31 is located directly under the traction wheel 6 on the clamp 2. Then, the lifting frame 50 is slightly lowered so that the traction wheel 6 on the clamp 2 is stuck in the traction hook 66 of the aerial storage position 31, so that the clamp 2 is connected with the traction mechanism of the aerial storage position 31. Finally, the traction mechanism of the aerial storage position 31 is used to pull the clamp 2 into the aerial storage position 31, so that the clamp 2 can be put into storage in the aerial storage position 31.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
