Description

Technical Field

[0001] The utility model relates to the technical field of rotor assembly, in particular to an automatic assembly line for automobile motor rotors. Background Art

[0002] The incoming automotive motor rotors are stacked piece by piece and need to be marked at their designated positions. The products are in a rotating state, so it is difficult to ensure that the placement corresponds to the actual marking position. When the products are flat, it also affects the subsequent marking accuracy. Since the products are piece by piece and not compacted, there are gaps in the middle and they need to be compacted. After the pre-pressing of the products, their height and plane need to be inspected. In the past, most of them were inspected separately, which had low inspection efficiency. There were burrs and flanging on the special-shaped through holes and the inner diameter of the products. The broken corners were inside during punching, so they also needed to be inspected by gauge. After the inspection, it was difficult to remove the materials because the bottom surface of the product was close to the tooling.

[0003] Based on the above defects and deficiencies, it is necessary to improve the existing technology and design an automatic assembly line for automobile motor rotors. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide an automatic assembly line for automobile motor rotors, which has a compact structure, integrates coding, pre-pressing, height detection, flatness detection, and through-gauge detection, has complete functions, high assembly and detection efficiency, and wide applicability.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide an automatic assembly line for automobile motor rotors, which includes:

[0009] A detection mechanism is provided at the pressurized height measuring station for pressurizing and detecting the height of the product and the flatness of the product surface;

[0010] A general inspection mechanism is provided at the general inspection station;

[0011] The pallet assembly line is arranged at the front end of the frame. The products are transported along the pallet assembly line and docked with each processing station in turn.

[0012] Preferably, the rotating tooling includes a rotating table mounted on the frame, a tooling plate mounted on the rotating table for placing the rotor, a plurality of positioning pins for positioning the arc-shaped opening of the inner diameter of the rotor are mounted on the tooling plate, two blocks for clamping the protrusion of the inner diameter of the rotor are mounted on the tooling plate, and a row of sensors for identifying the incoming rotor and detecting whether the rotor is flat are also embedded in the tooling plate. For rotors of different sizes, the installation positions of the positioning pins and the blocks can be adjusted. If the product is not fed in, the sensor cannot identify the rotor. If the rotor is not flat, a section of the bottom surface of the rotor is tilted, and the sensor below cannot identify the rotor.

[0013] Preferably, the marking device includes a camera mounted on the frame via a bracket for identifying the rotor size and marking position, a marking machine for marking a designated position on the rotor, and a code reader for scanning and identifying the marking.

[0014] Preferably, the prestressing device includes a prestressing bracket, a servo electric cylinder installed on the prestressing bracket, a lifting frame driven downward by the servo electric cylinder, and a pressure plate installed on the lower end of the lifting frame. A pressure sensor is installed at the connection between the servo electric cylinder and the lifting frame. Since the rotor incoming material is stacked together piece by piece and not compacted, there is a gap between the pieces and they need to be compacted. The rotor is radially limited and guided by the positioning boss to avoid collapse. By controlling the prestress in the axial direction, the edge burrs run outward and the burrs can be removed.

[0015] Preferably, the detection mechanism includes a tooling device installed on the frame, an inductive sensor and a pressure detection device, the tooling device includes a positioning platform, a reference block, a positioning component and a floating component, a reference block is installed in the middle of the positioning platform, the reference block is lower than the product and fixed when working, and the reference block is adjustable for products of different sizes. If the positioning platform is used as a reference, it is difficult for the pressure detection device to contact the bottom surface of the reference for relatively high products. A slide groove is provided on the positioning platform, and two positioning components for positioning from the inner diameter are installed in the slide groove. The positioning component includes a mounting block arranged in the slide groove and a mounting block fixed to the After adjusting the position of the positioning column on the mounting block, the mounting block is fixed to the positioning platform by screws to adapt to products of different sizes.

After the inspection is completed, the elastic column can lift the elastic block, and the product on the positioning platform is lifted. The bottom surface of the product is separated from the surface of the positioning platform, which is convenient for taking the product. Otherwise, the bottom surface of the product is close to the positioning platform without gaps, making it difficult to grab the product at the bottom when taking the product.

[0016] Preferably, the pressurized detection device includes a detection bracket, a detection servo electric cylinder installed on the top plate of the detection bracket, a detection lifting frame driven downward by the detection servo electric cylinder, a detection pressure head installed on the detection lifting frame, and a displacement sensor.

The detection lifting frame is also equipped with a number of contact displacement sensors distributed in a concentric array and passing through the detection pressure head. The multi-point contact displacement sensor detects the surface flatness of the product. Under the pressurized state, the flatness is judged by the changes in the values of multiple sensors. If the values are close, the flatness is good. If the values differ greatly, the product flatness is poor.

The go gauge lifting frame is connected to the go gauge detection bracket through a linear slide rail. The size and placement angle of the special-shaped go gauge are consistent with the special-shaped through holes on the product. The corresponding special-shaped go gauge is replaced according to different products. When the special-shaped through holes on the product are relatively dense and there is not enough space to install one-to-one special-shaped go gauges, the special-shaped go gauges can be placed in an interval manner. In this way, after one detection is completed, it is rotated by a certain angle to detect the next group of special-shaped through holes until all special-shaped go gauges are detected.

[0018] Preferably, the lower end of the positioning plate is provided with a boss consistent with the inner diameter of the product, which can detect the inner diameter of the product while detecting the special-shaped through hole. The positioning plate is also provided with a special-shaped opening to avoid the special-shaped through gauge. The purpose of detecting the inner diameter and the through hole is to detect the presence of burrs, flanging and punching cut angles inside.

[0019] Preferably, the pallet assembly line includes a conveying assembly line arranged on a frame, a pallet carrier placed on the conveying assembly line for positioning products, and a scanning assembly respectively arranged at the rear of the marking station, pre-pressing station, pressure height measuring station and gauge inspection station.

For rotors of different sizes, the installation positions of the positioning pins 213 and the clamping blocks 214 are adjustable. If the product is not in the feed, the sensor 215 cannot identify the rotor.

A pressure sensor is installed at the connection between the servo electric cylinder 332 and the lifting frame 333. Since the rotor incoming material is stacked together piece by piece and not compacted, there is a gap between the pieces and needs to be compacted. The rotor is radially limited and guided by the positioning boss 31 to avoid collapse. By controlling the pre-stress in the axial direction, the edge burrs run outward and the burrs can be removed.

[0055] The detection mechanism 4 includes a tooling device 41 installed on the frame 1, an inductive sensor 42 and a pressure detection device 43.
