Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automobile production equipment, in particular to a large assembly part storage turntable device, method and application. BACKGROUND

[0002] In the process of automobile production, many large assembly parts have large volume and mass, and they need to use forklifts or other large equipment during the transfer to the next production line for subsequent production. Due to the large volume and mass of the large assembly parts, the stacking of the material boxes loaded with assembly parts during storage can cause safety problems, so the storage of large assembly parts cannot be stacked. However, in the production process, the consumption of large assembly parts in the subsequent production process is relatively slow, and accumulation is prone to occur. Therefore, it is urgent to design a device for storing large assembly parts. SUMMARY

[0003] The present application aims to overcome the shortcomings of the prior art and provide a large assembly part storage turntable device, method and application.

[0004] The technical solution adopted by the present application to solve its technical problems is: A large assembly part storage turntable device, which can store and rotate large assembly parts, comprises a pedestal, an internal gear type rotary support, a driving gear, a speed reducer, a motor, a turntable and a fixed frame. The pedestal is fixed on the foundation. The internal gear type rotary support is coaxially installed on the upper surface of the pedestal and is arranged in the horizontal direction. The driving gear is arranged in the horizontal direction. The outer surface of the driving gear is gear meshed with the inner surface of the internal gear type rotary support and is installed on the upper surface of the pedestal. The driving gear can drive the internal gear type rotary support to move synchronously. The speed reducer and the motor are arranged in cooperation. The speed reducer and the motor are both installed below the pedestal. The speed reducer is coaxially connected with the driving gear through the pedestal. The motor can provide power. The speed reducer can reduce the speed, increase the torque and drive the driving gear to rotate. The turntable is arranged in the horizontal direction and is coaxially installed on the upper surface of the internal gear type rotary support. The turntable can rotate synchronously with the internal gear type rotary support. The fixed frame is arranged in multiple and is coaxially installed on the upper surface of the turntable. The multiple fixed frames can divide the upper area of the turntable into several storage areas. The large assembly parts can be detachably fixed in the storage area by the fixed frame. The storage area can provide storage space for the large assembly parts. The side of the fixed frame away from the shaft center of the turntable is arranged in an open manner.

[0005] Furthermore, the fixed frame is detachably connected to the turntable, allowing staff to adjust the installation position of the fixed frame in real time according to the size of large assemblies.

[0006] Furthermore, the device also includes a cylinder, a positioning pin, and a positioning hole. The cylinder is vertically oriented and mounted on the upper surface of the base. The cylinder is mounted on both sides of the moving gear, with the working end of the cylinder facing upwards. The positioning pin is vertically oriented and connected to the working end of the cylinder. The positioning hole is vertically oriented on the turntable. Each storage area of ​​the fixed frame is equipped with a positioning hole. The positioning hole and the positioning pin are vertically aligned, and the positioning pin and the positioning hole can cooperate with each other to lock and fix the turntable.

[0007] Furthermore, the device also includes a fence, a grating, and a gate. The fence is installed around the base and protects the base, internal gear slewing support, drive gear, reducer, motor, turntable, and fixed frame. The fence has openings on both sides, one side for forklift loading and the other side for worker access. A gate is installed on the forklift loading side, and a grating is installed on the worker access side. The grating can detect whether a worker is working and send an electrical signal to control the rotation of the turntable and the opening and closing of the gate.

[0008] The advantages and positive effects of this invention are as follows: 1. This invention uses a fixed frame to partition the turntable, enabling centralized storage of multiple large assemblies. This effectively solves the problems of large space occupation and low storage efficiency caused by the large size of the assemblies and their inability to be stacked in traditional storage methods, and significantly improves space utilization.

[0009] 2. The device of the present invention adopts a rotating structure, which allows forklifts to load materials from one side and workers to pick up materials from the other side, realizing the synchronous operation of loading and unloading, avoiding process interference, and greatly improving production cycle and overall operation efficiency.

[0010] 3. This invention uses a motor drive, and through the step-by-step transmission of a reducer, moving gear and internal gear rotary support, it achieves speed reduction and torque increase, ensuring that the turntable can still rotate smoothly when carrying large components, effectively preventing equipment damage caused by insufficient torque, and improving operational safety and service life.

[0011] 4. The device of this invention is equipped with a cylinder-driven positioning pin and positioning hole mating structure, which can achieve mechanical locking after the turntable rotates to the correct position, preventing gear damage due to external impact during loading and unloading. Simultaneously, the installation of the fence and light grating further ensures operational safety; the light grating can detect personnel status and control the turntable operation in conjunction, effectively preventing safety accidents.

Detailed Implementation

[0013] The present invention will be further described below with reference to the embodiments. The following embodiments are descriptive and not limiting, and should not be used to limit the scope of protection of the present invention.

[0014] The various experimental operations involved in the specific embodiments are all conventional techniques in the field. For parts not specifically annotated in this document, those skilled in the art can refer to various commonly used reference books, scientific and technological documents or related instructions and manuals prior to the filing date of this invention to carry out the operations.

[0015] A large assembly storage turntable device is provided, which can store large assemblies and rotate them for easy storage and retrieval by workers. Figures 1 to 9 As shown, the device includes a base 1, an internal gear rotary support 2, a moving gear 3, a reducer 4, a motor 5, a turntable 6, and a fixed frame 7. The base is fixed on the foundation. The internal gear rotary support is coaxially mounted on the upper surface of the base. The internal gear rotary support is arranged in a horizontal direction. The moving gear is also arranged in a horizontal direction. The outer surface of the moving gear meshes with the inner surface of the internal gear rotary support and is mounted on the upper surface of the base. The moving gear can drive the internal gear rotary support to move synchronously, thereby increasing the torque of the internal gear rotary support. The reducer and motor are designed to work together. Both the reducer and motor are installed below the base. The reducer passes through the base and is coaxially connected to the moving gear. The motor provides power, and the reducer reduces the speed and increases the torque to drive the moving gear to rotate, further increasing the torque generated during rotation. The turntable is set horizontally and coaxially mounted on the upper surface of the internal gear slewing support. The turntable can rotate synchronously with the internal gear slewing support. Multiple fixed frames are set and coaxially mounted on the upper surface of the turntable. The multiple fixed frames can divide the area above the turntable into several storage areas 11. Large assemblies can be detachably and fixedly placed in the storage areas through the fixed frames, and the storage areas can provide storage space for large assemblies. The side of the fixed frame away from the turntable axis is set with an opening 15, which makes it easy for forklifts to store large assemblies in the storage area through the gaps between adjacent fixed frames, and easy to retrieve.

[0016] The method of making and using the product as described above includes the following steps: (1) The forklift places the large assembly mounted on it on the storage area of ​​the fixed frame. After placement, the motor is started and the motor drives the gear to rotate through the reducer. (2) The moving gear drives the internal gear slewing support. Due to the structural arrangement between the reducer, the moving gear and the internal gear slewing support, the torque is increased by the size change of the reducer and the gear. In turn, the internal gear slewing support drives the turntable and the large assembly in the fixed frame on the turntable to rotate. (3) The forklift continues to place large assemblies in the storage area opposite to them after rotation, and the staff can take large assemblies from either side for production processing.

[0017] This invention, through the partitioned arrangement of a fixed frame, allows the device to simultaneously store multiple large assemblies. Workers can retrieve these assemblies from locations different from those requiring forklift storage, enabling synchronized work and reducing workflow interventions, thus improving production efficiency. The structural arrangement between the reducer, moving gear, and internal gear slewing support, with its progressively decreasing speed and increasing torque, reduces the risk of damage to large assemblies during rotation due to insufficient torque, thereby enhancing production safety.

[0018] In this embodiment, the fixed frame is detachably connected to the turntable, which allows staff to adjust the installation position of the fixed frame in real time according to large assemblies of different specifications, meeting different usage needs and further expanding the scope of application of this device.

[0019] In this embodiment, as Figures 5 to 9 As shown, the device also includes a cylinder 8, a positioning pin 9, and a positioning hole 10. The cylinder is vertically oriented and mounted on the upper surface of the base, on both sides of the drive gear. The working end of the cylinder faces upward. The positioning pin is vertically oriented and connected to the working end of the cylinder. The positioning hole is vertically oriented on the turntable. Each storage area of ​​the fixed frame is equipped with a positioning hole, which is vertically aligned with the positioning pin. The positioning pin and the positioning hole can cooperate to lock the turntable in place, preventing it from rotating. After the turntable moves to a new storage area, the cylinder is activated to insert the positioning pin into the positioning hole of that storage area, locking the turntable and preventing it from rotating. This avoids damage to the drive gear or the gears on the internal gear slewing support if the turntable rotates during the loading of large components by a forklift, which could cause damage.

[0020] Better, such as Figures 10 to 13 As shown, the device also includes a fence 12, a light grating 13, and a gate 14. The fence is installed around the base and protects the base, internal gear slewing support, moving gear, reducer, motor, turntable, and fixed frame. The fence has openings on both sides, one side for forklift loading (not labeled in the figure) and the other side for worker access (not labeled in the figure). The gate is installed on the forklift loading side, and the light grating is installed on the worker access side. The light grating detects whether a worker is working and sends an electrical signal to control the rotation of the turntable and the opening / closing of the gate. When a worker is accessing a large component, the light grating detects the worker's location on that side and uses the electrical signal to prevent the gate from opening and the turntable from rotating, thus preventing the forklift from bumping into the worker while loading large components and causing a safety accident.

[0021] The above-described device is used in the production of new energy vehicles.

[0022] Although embodiments of the invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations, and modifications are possible without departing from the spirit and scope of the invention and the appended claims. Therefore, the scope of the invention is not limited to the contents disclosed in the embodiments.
