Description

Technical Field

[0001] The invention relates to the technical field of automated production, in particular to an automatic positioning device for a vehicle stabilizer bar. Background Art

[0002] The automobile stabilizer bar (also known as anti-roll bar or anti-roll bar) is a key component in the vehicle suspension system. It is mainly used to reduce the roll of the vehicle when turning, improve the vehicle's handling performance and stability, and plays a vital role in improving vehicle safety and driving performance. It is an indispensable part of the modern automobile suspension system. At present, most of the production lines for automobile stabilizer bars include heating furnaces, blanking machines, forming machines, quenching pools and other devices. The main processes include heating, positioning, forming and quenching of the blank.

[0003] In the prior art, the production of stabilizer bars still relies on manual operation. For example, before the stabilizer bar blank is formed, it needs to be manually transported, centered and positioned on the end face to ensure the centering and end face verticality of the stabilizer bar blank being formed in the forming machine. However, manual positioning has many disadvantages. First, the low accuracy of manual positioning leads to poor quality consistency of the produced stabilizer bars, making it difficult to ensure product quality. Secondly, manual efficiency is low, cost is high, and labor intensity is high. If the processed stabilizer bar is of large quality, multiple people are required to coordinate the transport and positioning. In addition, due to the high temperature of the stabilizer bar blank, the safety risks during manual transport and positioning operations are high. Finally, manual production flexibility is low, it is difficult to quickly adjust production plans and processes, and the ability to respond to changes in market demand is weak.

[0004] For example, publication number CN 113020350A discloses an automatic positioning and bending production line for stabilizer bars. The positioning device designed in this design relies on the sequential control of each mechanical module to achieve the centering and end face positioning of the stabilizer bar blank. However, this solution involves too many actuators, which is costly and difficult to maintain. Secondly, this solution ignores the adaptability to various types of stabilizer bar blanks. If the length of the stabilizer bar changes, its truss manipulator needs to be adjusted accordingly to ensure the centering of the stabilizer bar blank when it enters the bending device. The production flexibility is low and it is difficult to quickly adjust the production plan. To this end, we provide an automatic positioning device for automobile stabilizer bars. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic positioning device for automobile stabilizer bars, which realizes automatic operation by using sensors, control systems and actuators. High-precision sensors and control systems ensure the positioning accuracy and consistency of each stabilizer bar.

By replacing manual operation with the automatic equipment, the risk of workers being injured during operation is reduced, and the entire positioning process is completely completed by the machine.

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0026] See also Figure 1-4 As shown, an automatic positioning device for automobile stabilizer bars comprises a blanking component 1 for connecting a boiler and a positioning and centering component 2, wherein the blanking component 1 and the positioning and centering component 2 are arranged in a row; after being heated by a boiler, the stabilizer bar blank rolls down from the outlet inclined plate of the boiler onto the blanking component 1, and is transported to a supporting structure 3 on the positioning and centering component 2 through the blanking component 1, and then performs centering positioning and end face positioning;

[0027] Specifically, the unloading assembly 1 includes two identical chain plate conveyor belts 102, which are arranged side by side in parallel. Two groups of support frames 101 are arranged at the bottom of each chain plate conveyor belt 102, and each two groups of support frames 101 fix one chain plate conveyor belt 102 to the ground; since the temperature of the stabilizing bar is relatively high after being heated by the heating furnace, the chain plates of the chain plate conveyor belt 102 are made of high temperature resistant materials, and vertical baffles 103 are evenly and vertically fixed on the outer peripheral chain plates of each chain plate conveyor belt 102, and the vertical baffles 103 on the two chain plate conveyor belts 102 are in the same corresponding positions;

[0028] The positioning and centering assembly includes a frame 201 located at the end of the blanking assembly 1, a slide rail 203 is fixedly installed at the edge position of one side of the top of the frame 201, a rotating block 204 driven by a motor is rotatably installed at the middle position of the slide rail 203, and clamping arms 202 are symmetrically arranged on both sides of the rotating block 204. The two clamping arms 202 are slidably matched with the slide rail 203, and a crank 205 is arranged between each clamping arm 202 and the rotating block 204, and the two ends of the crank 205 are respectively hinged to a clamping arm 202 and the rotating block 204;

[0029] A positioning plate 207 is installed at the end of one of the clamping arms 202 away from the crank 205, and a pressure sensor 206 is provided between the positioning plate 207 and the mounting surface of the clamping arm 202; a mounting frame is fixed to the end of the other clamping arm 202 away from the crank 205, and a support plate 208 is rotatably mounted on the side of the mounting frame through a bearing 209, and a motor for driving the support plate 208 to rotate is provided in the mounting frame, and a distance sensor 210 is also provided on the end surface of the mounting frame;

[0030] Two groups of support structures 3 are fixedly installed in the groove at the top of the frame 201, and each group of support structures 3 consists of two roller brackets 301 arranged opposite to each other. The roller brackets 301 are fixed in the groove at the top of the frame 201, and a V-shaped roller 303 is rotatably mounted between the two roller brackets 301, and guide limit blocks 302 fixed to the corresponding roller brackets 301 are arranged on both sides of the V-shaped roller 303 to ensure that the stabilizer bar blank can fall onto the V-shaped roller 303 normally, and a second pressure sensor is installed under the rotating axis of the V-shaped roller 303; it should be noted that the V-shaped roller 303 is set to be V-shaped so that it can adapt to stabilizer bar blanks with different rod diameters.

[0031] The automatic positioning device also includes an electrical control module, including a PLC controller and a control panel. The control panel is provided with a start / stop button for starting and stopping the device. Each sensor is electrically connected to the PLC controller. The PLC controller collects signals through each sensor and processes and judges the output signals of the control panel, and outputs control signals to each execution component to complete the specified action.

[0032] When the present invention is in use, the stabilizer bar blank is transported to the top of the positioning and centering component 2 by the chain plate conveyor 102, and falls onto the two V-shaped rollers 303 under the action of gravity. At this time, the pressure value collected by the stabilized pressure sensor 2 is compared with the set threshold range. When the pressure value is within the threshold range, it is determined that the stabilizer bar blank has fallen onto the V-shaped roller 303 at this time, otherwise it is determined that the stabilizer bar blank has not fallen onto the V-shaped roller 303;

[0033] If it is determined that the stabilizing bar blank has fallen onto the top of the V-shaped roller 303, a clockwise rotation signal is sent to the driving motor of the rotating block 204 through the PLC controller, and the rotating block 204 drives two symmetrically arranged clamping arms 202 to slide toward each other along the slide rail 203 through the crank 205, so that the center position of the stabilizing bar blank can always be on the straight line where the center of the rotating block 204 is located, so that the subsequent grasping position of the stabilizing bar blank by the manipulator is always the same coordinate position, so there is no need to adjust the grasping position of the manipulator, thereby achieving adaptability to stabilizing bar blanks with different rod lengths;

[0034] During the process of clamping and positioning the stabilizer bar blank by the two clamping arms 202, when the pressure value of the pressure sensor 1 206 is compared with the set threshold value, when the pressure value reaches the threshold value, it indicates that the two clamping arms 202 have completed the positioning and centering and provided sufficient clamping force; the PLC controller sends a locking signal to the driving motor of the rotating block 204, so that the output shaft of the driving motor is locked to maintain the clamping state of the two clamping arms 202 on the stabilizer bar blank;

[0035] Subsequently, the PLC controller sends a start signal to the motor on the mounting frame, and the output shaft of the motor drives the support plate 208 to rotate clockwise, and simultaneously determines whether the distance values ​​of the distance sensor 210 are equal. When the distance values ​​collected by the distance sensor 210 are equal, it is determined whether the end face of the stabilizer bar blank is in a vertical state, that is, Figure 3 If the stabilizer bar blank is in the state shown in the figure, the PLC controller sends a stop signal to the motor, and the motor stops rotating immediately, thereby completing the end face positioning of the stabilizer bar blank;

[0036] After a certain delay (generally set to 1 second), the PLC controller sends a counterclockwise rotation signal to the drive motor of the rotating block 204, and the clamping arms 202 on the left and right sides are released and return to the initial position.

[0037] At this point, the stabilizer bar blank has completed the centering positioning and end face positioning, waiting to be grabbed by the robot. When the pressure value of pressure sensor 2 reaches another set threshold, it means that the positioned stabilizer bar blank has been grabbed and removed by the robot, thus entering the next cycle to achieve continuous operation of the entire equipment.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
