Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake systems, in particular to a quality detection device for automobile brake discs. Background Art

[0002] With the rapid development of the automobile industry, automobile safety performance has attracted more and more attention. As an important part of the automobile braking system, the brake disc is responsible for generating friction when the vehicle brakes, so as to slow down or stop the vehicle. Nowadays, people are keen on going on self-driving tours in the wild. When encountering a long downhill road, they need to use the brakes frequently, and the temperature of the brake disc will increase significantly. Under such working conditions, the quality of the brake disc directly affects the safety and driving comfort of the car. The quality inspection of brake discs in the current market is to measure whether the quality of the brake disc is qualified by detecting the end face runout of the brake disc at room temperature. Now the market is in urgent need of a quality inspection device that can simulate a high-temperature braking environment and efficiently inspect the quality of automobile brake discs. Utility Model Content

[0003] In order to solve the problems that automobile brake discs detected under normal temperature conditions cannot meet the quality requirements under high temperature conditions, and that detection devices currently on the market generally have the disadvantages of complicated installation and fixation and low detection efficiency, the utility model provides a detection device for measuring the quality of automobile brake discs by simulating the automobile braking environment and combining simulation, fixation and detection.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A vehicle brake disc quality inspection device comprises a flat base, a vertical axis, a horizontal platform, a positioning rod, a main oil pump, an oil pipe, a first support seat, a second support seat, a brake friction block action assembly, a first brake friction block, a second brake friction block, a first hydraulic cylinder, a second hydraulic cylinder, a brake disc inspection assembly, a support arm, a rotating bearing, a pressure plate, a rotating drive assembly, a control module, and an oil tank.

[0006] The car brake disc is placed on the horizontal platform. After the positioning rods are all passed through the bolt holes of the brake disc, the staff presses the start detection command, and the rotation drive assembly starts to rotate, driving the vertical shaft to rotate. The vertical shaft rotation drives the main oil pump on the shaft to start working, and at the same time drives the horizontal platform at the upper end of the vertical shaft to rotate. The hydraulic oil is sucked from the oil tank into the main oil pump, and is pumped into the first hydraulic cylinder after being pressurized by the main oil pump. The piston rod of the hydraulic cylinder extends outward, pushing the brake friction block action component to move. The action of the brake friction block action component pushes the first brake friction block and the second brake friction block to clamp the brake disc, simulating the braking environment. The hydraulic oil is sucked from the oil tank into the main oil pump, and is pumped into the second hydraulic cylinder after being pressurized by the main oil pump. The piston rod of the hydraulic cylinder extends outward, pushing the pressure plate to press the brake disc.

[0007] As the speed of the rotating drive assembly increases, the speed of the vertical shaft also increases, the oil pressure output by the oil pump also increases, the pressure plate's pressing force on the brake disc also increases, the brake friction block clamps the brake disc tighter, the friction force increases, and the temperature of the brake disc increases. Controlling the speed of the electric drive assembly can control the temperature of the brake disc.

[0008] When the shutdown command is issued, the rotating drive assembly stops working, the main oil pump also stops working, the oil pressure gradually decreases, the piston rod of the first hydraulic cylinder and the piston rod of the second hydraulic cylinder retract back into the cylinder, and the first brake friction pad, the second brake friction pad, and the pressure plate return to the ready position before starting.

[0009] Compared with the prior art, the automobile brake disc quality detection device has the following beneficial effects:

[0010] The utility model achieves the beneficial effect of detecting the quality of automobile brake discs in a simulated automobile braking environment by arranging a flat base, a vertical axis, a horizontal carrier, a positioning rod, a main oil pump, an oil pipe, a first support seat, a second support seat, a brake friction block action component, a first brake friction block, a second brake friction block, a first hydraulic cylinder, a rotation drive component, an oil tank, a control module, etc.

[0011] The utility model realizes the beneficial effect of automatically tightening the brake disc when detecting the quality of the automobile brake disc by arranging a flat base, a vertical axis, a horizontal carrier, a positioning rod, a main oil pump, an oil pipe, a first support seat, a second hydraulic cylinder, a brake disc detection component, a support arm, a rotating bearing, a pressure plate, a rotating drive component, a control module, an oil tank, etc.

[0012] The utility model simulates the braking environment of an automobile. When testing the automobile brake disc, the braking environment is simulated and the brake disc is pressed and rotated, thereby achieving the beneficial effects of testing the automobile brake disc under high temperature conditions, simple testing installation and fixing, and high testing efficiency.

[0022] like Figure 1-Figure 3 As shown, the utility model provides a quality inspection device for automobile brake discs, including a flat base 1, a vertical shaft 2 is arranged in the center of the flat base 1, and the shaft 2 is rotatably connected to the flat base 1. A horizontal platform 3 is fixedly connected to the upper end surface of the shaft 2. A horizontal boss 4 is arranged in the center of the horizontal platform 3, and the diameter of the horizontal boss 4 is not larger than the center hole diameter of the automobile brake disc 5, and just passes through the center hole of the automobile brake disc 5. The rotation centers of the horizontal platform 3 and the horizontal boss 4 are both on the extension line of the axis of the shaft 2. The height of the horizontal boss 4 is slightly lower than the height of the shaft hole of the automobile brake disc 5, and three positioning rods 7 corresponding to the fixing holes of the automobile brake disc 5 are evenly arranged along the circumference of the horizontal platform 3, and the height of the positioning rod 7 is slightly lower than the height of the fixing hole of the automobile brake disc 5, and the diameter of the positioning rod 7 is not larger than the screw hole diameter of the automobile brake disc 5, and just passes through the screw hole of the automobile brake disc 5.

[0023] A main oil pump 6 is arranged on the upper part of the vertical shaft 2 below the horizontal platform 3 , and the vertical shaft 2 is a main oil pump 6 whose pump shaft passes vertically through the main oil pump 6 .

[0024] The rotation of the main oil pump 6 generates negative pressure to suck the hydraulic oil from the oil tank 28 into the main oil pump 6 through the oil pipe 8, and then the boosting effect generated by the rotation of the impeller boosts the hydraulic oil and delivers it to each boosting oil pipe 8, and then enters the first hydraulic cylinder 18, the second hydraulic cylinder 19, and the third hydraulic cylinder 20, thereby pushing the piston rods of the first hydraulic cylinder 18, the second hydraulic cylinder 19, and the third hydraulic cylinder 20 to extend.

[0025] A first support seat 9 is arranged on the right side of the flat base 1 , and a second support seat 10 is arranged between the first support seat 9 and the vertical shaft 2 .

[0026] The first rotating link 12 and the second rotating link 13 horizontally and laterally pass through the first supporting seat 9 and the second supporting seat 10 respectively.

[0027] The first rotating link 12 and the second rotating link 13 are respectively connected to the first support seat 9 and the second support seat 10. One end of the first rotating link 12 is fixedly connected to the first brake friction block 16, and the other end is fixedly connected to the first link 14.

[0028] One end of the second rotating link 13 is fixedly connected to the second brake friction block 17, and the other end is fixedly connected to the second link 15.

[0029] The piston rod of the first hydraulic cylinder 18 is fixedly connected to one end of the push-pull bracket 21 , and the other end of the push-pull bracket 21 is rotatably connected to the first connecting rod 14 and the second connecting rod 15 , respectively.

[0030] The first brake friction block 16 and the second brake friction block 17 are symmetrically and horizontally arranged on the upper and lower sides of the automobile brake disc 5, and maintain a gap of the same distance from the automobile brake disc 5. The size of the gap is sufficient to ensure that when the first brake friction block 16 and the second brake friction block 17 are rotated, the first brake friction block 16 and the second brake friction block 17 can symmetrically and simultaneously rub against the automobile brake disc 5 and generate the same friction force.

[0031] When the piston rod of the first hydraulic cylinder 18 telescopes, the first rotating rod 12 and the second rotating rod 13 rotate in opposite directions, driving the first brake friction block 16 and the second brake friction block 17 to swing in opposite directions, clamping the automobile brake disc 5. The faster the automobile brake disc 5 rotates, the greater the hydraulic oil pressure, the greater the pressure of the first brake friction block 16 and the second brake friction block 17 clamping the automobile brake disc 5, the greater the friction force on the automobile brake disc 5, the greater the heat generated by the friction between the first brake friction block 16, the second brake friction block 17 and the automobile brake disc 5, and the higher the temperature on the upper and lower sides of the brake disc.

[0032] A support arm 22 is horizontally arranged on the top of the first support seat 9. Below the support arm 22, just vertically above the automobile brake disc 5, a second hydraulic cylinder 19 is arranged. The bottom of the second hydraulic cylinder 19 is fixedly connected to the lower plane of the support arm 22. The piston rod of the second hydraulic cylinder 19 faces the automobile brake disc 5 and is arranged perpendicular to the plane of the automobile brake disc 5. The end of the piston rod of the second hydraulic cylinder 19 facing the automobile brake disc 5 is connected to a rotating bearing 23. The rotating bearing 23 is fixedly connected to a circular pressure plate 24 and can only rotate in a plane parallel to the plane of the automobile brake disc 5. The outer diameter of the pressure plate 24 is the same as the outer diameter of the positioning rod 7. During operation, the pressure plate 24 presses on the automobile brake disc 5 to limit the displacement of the automobile brake disc 5 in the up and down directions. The rotation of the automobile brake disc 5 drives the pressure plate 24 to rotate.

[0033] The rotation centers of the vertical shaft 2, the main oil pump 6, the horizontal platform 3, the horizontal boss 4, the pressure plate 24, and the driven rotating gear plate 25 are kept on the same vertical straight line.

[0034] A variable frequency electric drive 27 is arranged below the flat base 1, and the variable frequency electric drive 27 is fixedly connected to the flat base 1 through three support columns. The output shaft of the variable frequency electric drive 27 passes through the flat base 1 and is in transmission connection with the active rotating gear disc 26. A driven rotating gear disc 25 is arranged horizontally below the vertical shaft 2, and the active rotating gear disc 26 and the driven rotating gear disc 25 are engaged with each other.

[0035] A third support seat 11 is vertically arranged on the right side of the flat base 1, and a third hydraulic cylinder 20 is horizontally arranged on the top of the third support seat 11 to the left, and a laser scanner sensor 30 and an infrared thermometer sensor 31 are fixedly connected to the left end of the piston rod of the third hydraulic cylinder 20. When the laser scanner sensor 30 and the infrared thermometer sensor 31 are in the working position, they face the automobile brake disc 5 vertically downward, and the data is transmitted to the control module 29 through the wire.

[0036] After the automobile brake disc 5 is placed on the horizontal platform 3 and the three positioning rods 7 are all passed through the bolt holes of the automobile brake disc 5, the staff issues a start detection command, the variable frequency electric drive 27 starts to rotate, the active rotating gear disc 26 rotates accordingly to drive the driven rotating gear disc 25 to rotate, the driven rotating gear disc 25 drives the vertical shaft 2 to rotate, the vertical shaft 2 rotates to drive the main oil pump 6 on the shaft to start working, and at the same time drives the horizontal boss 4, the horizontal platform 3, and the horizontal pressure plate 24 at the upper end of the vertical shaft 2 to rotate. The hydraulic oil is sucked into the main oil pump 6, and is conveyed into the first hydraulic cylinder 18, the second hydraulic cylinder 19, and the third hydraulic cylinder 20 after being pressurized by the main oil pump 6. The piston rod of the hydraulic cylinder extends outward, pushing the first brake friction block 16 and the second brake friction block 17 to clamp the automobile brake disc 5, pushing the pressure plate 24 to press the automobile brake disc 5, and the laser scanner sensor 30 and the infrared thermometer sensor 31 detect the working position.

[0037] As the speed of the variable frequency electric drive 27 increases, the speed of the vertical shaft 2 also increases, the oil pressure output by the oil pump increases, the pressing force of the pressure plate 24 on the automobile brake disc 5 increases, the first brake friction block 16 and the second brake friction block 17 clamp the automobile brake disc 5 more and more tightly, the friction force increases, and the temperature of the automobile brake disc 5 increases. Controlling the speed of the variable frequency electric drive 27 controls the temperature of the automobile brake disc 5.

[0038] When the shutdown command is issued, the variable frequency electric drive component 27 stops working, the main oil pump 6 also stops working, the oil pressure gradually decreases, the piston rods of the first hydraulic cylinder 18, the second hydraulic cylinder 19, and the third hydraulic cylinder 20 shrink into the cylinders, and the first brake friction block 16, the second brake friction block 17, the pressure plate 24, the laser scanner sensor 30, and the infrared thermometer sensor 31 gradually return to the ready position before starting.

This application is intended to cover any variations, uses or adaptations of the present invention, which follow the general principles of the present invention and include common knowledge or customary technical means in the art that are not disclosed in the present invention.
