Description

Technical Field

[0001] The present invention relates to the technical field of transmission devices, and more specifically to a transmission device for manufacturing mechanical and electrical equipment. Background Art

[0002] The transmission device used in the manufacture of mechanical and electrical equipment plays an important role in the field of industrial automation. It is responsible for transmitting electrical equipment from one workstation to another during the manufacturing process to improve production efficiency. During the transmission process, components such as timing motors and rotating gears work together to achieve intermittent and timed transportation of electrical equipment and prevent equipment from piling up on the first conveyor belt.

[0003] There are some problems in the use of existing transmission devices for mechanical and electrical equipment manufacturing, as follows: During the manufacturing and transmission process of mechanical electrical equipment, the equipment will fall directly on the top of the transmission device, and in order to ensure that the transmission device can effectively support the electrical equipment, the transmission device is made of metal. When the electrical equipment is transmitted, the equipment falls to the transmission device, which will cause the equipment to collide with the transmission device, thereby causing the electrical equipment to be damaged or the outer shell to be damaged due to the collision. Therefore, it is not convenient to ensure the normal transportation of the equipment. In addition, during the transportation of the equipment, the conveyor belt runs, and the inertia of the equipment itself will cause relative displacement between the equipment and the conveyor belt, which will cause scratches on the surface of the equipment. Therefore, it is not convenient to ensure the integrity of the equipment. Summary of the invention

[0007] Furthermore, the transmission assembly includes a first positioning shaft, the front and back sides of the first positioning shaft are fixedly connected with circular limit plates, the front and back sides of the outer side of the first positioning shaft are sleeved with a first waist plate, and the front and back sides of the outer side of the first positioning shaft are located on the inner sides of the two first waist plates and are movably sleeved with a second waist plate.

[0008] Furthermore, the buffer assembly includes a conveying positioning plate, positioning bearings are installed on both sides of the front and back sides of the conveying positioning plate, a second positioning shaft is installed on the inner side of the positioning bearing, a telescopic assembly is installed on the top of the conveying positioning plate, a second pulling plate is movably sleeved on the outer side of the telescopic assembly, and the front and back sides of the bottom of the second pulling plate are fixedly connected with L-shaped positioning plates, and the inner sides of the two L-shaped positioning plates are fixedly connected with limiting strips.

[0009] Furthermore, the telescopic assembly includes a lifting block, a lifting slot is provided at the bottom of the lifting block, a telescopic spring is fixedly connected to the top of the lifting slot, a pulling square block is fixedly connected to the middle of the top of the lifting slot, a first square limit block is movably connected to the inner side of the lifting slot, a connecting positioning block is fixedly connected to the bottom of the first square limit block, and a second square limit block is fixedly connected to the bottom of the pulling square block.

[0010] Furthermore, one end of the second positioning shaft away from the conveying positioning plate is fixedly connected to the circular limiting plate, the number of the first positioning shafts is twice the number of the conveying positioning plates, and the distance between the L-shaped positioning plate and the limiting bar is twice the thickness of the first pulling plate.

[0011] Furthermore, the height of the middle part of the guide plate is in the same plane as the middle part of the distance between the L-shaped positioning plate and the limit strip, and the tops of the second pulling plate, the conveying positioning plate, the connecting positioning block and the first square limit block are provided with square grooves, and the sizes of the square grooves of the second pulling plate, the conveying positioning plate, the connecting positioning block and the first square limit block have a clearance match with the sizes of the pulling square block, the cross-sectional size of the lifting groove has a clearance match with the size of the top of the first square limit block, the bottom opening size of the lifting groove has a clearance match with the size of the connecting positioning block, and the bottom of the connecting positioning block is fixedly connected to the top of the conveying positioning plate.

[0013] Technical effects and advantages of the present invention: During the transportation of electrical equipment, the present invention first drives the rotating shaft to rotate through the operation of the servo motor, and then drives the two transmission gears on the outer side of the rotating shaft to rotate. Then, the teeth on the outer side of the transmission gear rotate to drive the space formed between the two adjacent first positioning shafts to rotate, thereby causing the transmission component to rotate and then driving the buffer component to follow the movement of the transmission component through the circular limit plate, thereby achieving the purpose of transmitting the electrical equipment.

[0014] When the device falls to the top of the buffer assembly, the lifting block is pressed down under the action of the device's own weight, so that the lifting block, the pulling square block and the second square limit block descend relative to the connecting positioning block and the first square limit block, and then the telescopic spring is compressed, thereby slowing down the potential energy of the device's fall, avoiding the device from falling directly. The gravity of the fall causes the device to hit the transmission device, which may cause damage to the electrical equipment or damage to the outer shell due to the collision, effectively avoiding damage to the electrical equipment during transportation.

[0015] When the device of the present invention falls to the top of the buffer component, the bottom of the device will compress the telescopic component located at the bottom of the device according to the bottom area of ​​the device, and the telescopic component not located at the bottom of the device will maintain its original position. Therefore, a height difference will be formed between the telescopic component located at the bottom of the device and the top of the telescopic component not located at the bottom of the device, so that the electrical device can be positioned to avoid relative displacement between the electrical device and the conveyor belt due to its own inertia when the transmission device is running, thereby causing scratches on the surface of the device, thereby ensuring the integrity of the device casing.

[0016] When the present invention needs to adjust the rebound height of the top of the transportation equipment when transporting different equipment, or when the rebound of the telescopic component is not needed to slow down the potential energy of the electrical equipment falling, the hydraulic cylinder works to drive the hydraulic rod to contract, and then drives the positioning cross bar and the L-shaped connecting positioning plate to descend, and then drives the first pulling plate to descend so that the connecting rubber is stretched. The descent of the first pulling plate will pull the L-shaped positioning plate and the limit bar located at the top of the first pulling plate to descend, and then drive the second pulling plate to descend, thereby pulling the second square limit block, the pulling square block and the lifting block to descend relative to the transportation positioning plate, so as to achieve the purpose of adjusting the displacement of the lifting block relative to the connecting positioning block. During the operation of the conveying device, under the guidance of the guide plate and the connecting rubber, the buffer component will be pulled to the specified elastic position by the first pulling plate when it moves to the top of the first pulling plate, and the telescopic component will no longer move elastically when it falls to the lowest point, so that the state of the telescopic component can be adjusted when the transportation equipment transports different equipment, which is convenient for adjustment according to actual transportation conditions.
