Description

Technical Field

[0001] The invention relates to the technical field of brake detection, and in particular to a feeding mechanism for a brake detection device. Background Art

[0002] Brake discs, also known as brake discs, are key friction components on automotive disc brakes. Brake discs are usually mounted on wheel bearings. When the driver steps on the brake pedal, the piston in the brake caliper is pushed and the brake pads are clamped to both sides of the brake disc. Due to the existence of friction, the brake disc will be affected by the friction force applied by the brake, causing the vehicle to slow down or stop moving. Therefore, during the production process of brake discs, the parallelism of the brake discs needs to be tested to ensure the service life of the brake discs.

[0003] A Chinese patent with authorization announcement number CN113686294B discloses a reference plane parallelism detection device for brake disc production and processing, which includes a detection platform, the detection platform includes a rotating device, a first electric telescopic rod and a detection device, the rotating device is arranged on the top of the brake disc, and is used to drive the brake disc to rotate, the rotating device includes a motor, the bottom of the motor is fixedly connected with a rotating ring, the bottom of the rotating ring is fixedly connected with two positioning shafts, the first electric telescopic rod is fixed to the top of the detection platform, the detection device includes a fixed plate, the top of the fixed plate is fixedly connected with a control box, the top of the control box is fixedly connected with an indicator light, and one side of the control box is fixedly connected with two inclined pressure sensors, the top of the fixed plate is fixedly connected with a pressure spring, the top of the pressure spring is fixedly connected with a T-shaped movable rod, the bottom of the T-shaped movable rod passes through the fixed plate and is fixedly connected with an arc surface resistance rod, and the top of the T-shaped movable rod is fixedly connected with a lifting trigger head used in conjunction with the pressure sensor.

[0004] The above patent sets two detection devices, which can detect the parallelism of the top of the brake disc when the rotating device drives the brake disc to rotate. If there is a bulge or depression on the top of the brake disc, the indicator light will light up. By observing whether the indicator light is on, the parallelism of the top plane of the brake disc can be grasped, which is convenient for quickly removing unqualified brake discs during the brake disc processing process. There is no need for naked eye observation or manual measurement, and the parallelism of the brake disc can be grasped quickly and accurately.

[0005] However, the above patent requires that the brake disc be manually loaded onto the test bench, and that it be manually unloaded after the test is completed, which is time-consuming and labor-intensive. Summary of the invention

[0006] The present invention provides a feeding mechanism for a brake detection device, aiming to solve the problem in the related art that a brake disc needs to be installed manually.

[0007] The feeding mechanism for the brake detection device of the present invention comprises: a detection platform, a feeding mechanism, a discharging mechanism and a positioning assembly;

[0008] The testing platform comprises an inner ring and an outer ring, the inner ring and the outer ring are spaced apart, a plurality of testing discs are arranged between the inner ring and the outer ring, a first driving member is arranged inside the testing platform, the first driving member is used to drive the testing disc to rotate around the testing platform, and the testing disc is used to detect the flatness of the brake disc;

[0009] The positioning assembly includes a positioning block, a positioning disk and a positioning plate. The positioning block is fixedly connected to the detection table and is located at the end of the feeding mechanism. The positioning block is a ramp block and is provided with an avoidance groove. The positioning disk is provided on the detection disk. A plurality of first positioning rods and second positioning rods are provided on the positioning disk. The plurality of first positioning rods are distributed at intervals. The second positioning rods are slidably matched with the positioning disk and are connected to the positioning disk through a first elastic member. There are two positioning plates, which are respectively connected to the inner ring and the outer ring. The two positioning plates are distributed at intervals on both sides of the avoidance groove. There is a gap between the positioning plate and the inner ring or the outer ring, and the positioning plate can stop against the brake disk.

[0010] Beneficial effect: the feeding mechanism transports the brake disc to the positioning block, so that the brake disc is distributed obliquely. At this time, the detection disc and the positioning disc are located below the positioning block, and the first driving member is used to make the detection disc rotate circumferentially around the detection platform. During this process, the second positioning rod gradually approaches the inner hole wall of the brake disc and stops therewith, and the second positioning rod pushes the brake disc close to the positioning plate. When the brake disc and the positioning plate stop, the detection disc continues to rotate, which will cause the first elastic member to contract and the second positioning rod to move toward the center of the positioning disc. When the second positioning rod moves to the inner end of the slide groove, the second positioning rod pushes the brake disc into the gap between the positioning plate and the inner ring or the outer ring, thereby placing the brake disc on the positioning disc. When the brake disc is flush with the positioning disc, the first positioning rod is located in the inner hole of the brake disc, and the first elastic member releases the elastic force and stretches, thereby pushing the second positioning rod to move outward, so that the first positioning rod and the second positioning rod both stop against the inner hole wall of the brake disc, thereby making the brake disc and the positioning disc coaxially distributed, completing the positioning of the brake disc.

[0011] Preferably, a separation block is further provided on the detection table, which is located at the head end of the discharging mechanism. The separation block is a slope block, the bottom end of which is flush with the inner ring or the outer ring, and the top end of which is flush with the discharging mechanism.

[0012] The effect is that the separating piece is used to separate the brake disk from the positioning disk.

[0013] Preferably, a baffle is further provided on the separation block, and the baffle is used to prevent the brake disc from separating from the separation block. The baffle is also rotatably matched with a paddle, and a second driving member is provided on the baffle, and the second driving member is used to drive the paddle to rotate.

[0014] The effect is that the second driving member drives the dial plate to rotate, thereby moving the brake disc on the separation block to the discharge mechanism, thereby realizing automatic unloading.

[0016] The effect is that the positioning disc moves along the first tooth groove, thereby driving itself to rotate. The positioning disc drives the brake disc to rotate through the first positioning rod and the second positioning rod. The two detection heads respectively stop against the upper surface and the lower surface of the brake disc, and the flatness of the brake disc can be detected when the brake disc rotates.

[0017] Preferably, a limiting pin is provided at the bottom of the positioning plate, and the limiting pin is elastically connected to the positioning plate and can extend into the matching groove.

[0018] The effect is that the limiting pin extends into the matching groove, thereby achieving a clamping connection between the positioning disc and the detection disc, preventing the positioning disc from rotating, resulting in failure to position the brake disc.

[0019] Preferably, the inner ring is provided with a second tooth groove, the second tooth groove can engage with the positioning plate, the positioning plate is provided with a coil, the coil is rotatably engaged with the positioning plate through a one-way bearing, a pull rope is wound around the coil, the pull rope is connected to the mounting seat, the mounting seat is slidably engaged in the mating groove, and the mounting seat is connected to the mating groove through a second elastic member.

[0023] By adopting the above technical solution, the beneficial effects of the present invention are:

[0024] When the brake disc is aligned with the positioning disc, the first positioning rod is located in the inner hole of the brake disc, and the first elastic member releases the elastic force and stretches, thereby pushing the second positioning rod to move outward, so that the first positioning rod and the second positioning rod both stop against the inner hole wall of the brake disc, so that the brake disc and the positioning disc are coaxially distributed, and the positioning of the brake disc is completed.

[0043] like Figures 5 to 8 As shown, a mating groove 201 is provided on the detection disk 2, and the mating groove 201 extends radially along the detection disk 2. A mounting seat 10 is slidably fitted in the mating groove 201. The mounting seat 10 is fixedly connected to the mating groove 201 through a second elastic member 12.

A limiting pin 521 is also provided at the bottom of the positioning plate 52, the limiting pin 521 is a hemispherical structure, the limiting pin 521 is elastically connected to the positioning plate 52, and can be received in the positioning plate 52, and the limiting pin 521 can also extend into the matching groove 201, so that it is engaged with the matching groove 201, thereby limiting the rotation of the positioning plate 52. A coil 13 is also provided on the positioning disk 52, and the coil 13 is rotatably engaged with the positioning disk 52 through a one-way bearing 14. A slot is provided on the outer wall of the one-way bearing 14, and a clamping block 131 is provided on the inner wall of the coil 13. The clamping block 131 can extend into the slot, thereby realizing the clamping connection between the one-way bearing 14 and the coil 13. The outer side of the coil 13 is rotatably engaged with a mounting ring 15, and the mounting ring 15 is elastically connected to the detection disk 2 through a third elastic member 16. The third elastic member 16 is an elastic column. A pull rope 17 is wrapped around the coil 13, and the end of the pull rope 17 is fixedly connected to the mounting seat 10. The detection disk 2 is also provided with a limit block 18, which is a rectangular block with a curved surface structure at the top. Multiple limit blocks 18 are evenly spaced along the circumference of the detection disk 2. The limit block 18 is elastically connected to the detection disk 2. The limit block 18 can be received in the detection disk 2. The bottom end of the coil 13 is also provided with a limit groove 132, and the limit block 18 can extend into the limit groove 132, thereby unidirectionally limiting the coil 13 to prevent the coil 13 from rebounding. The inner ring 101 is also provided with a reset block 19, which is a bevel block fixedly connected to the side wall of the inner ring 101. The reset block 19 can stop against the mounting ring 15, thereby pushing the mounting ring 15 to move upward.

[0045] According to the feeding mechanism for the brake detection device of the embodiment of the present invention, in the initial state, the detection disk 2 and the positioning disk 52 are located directly below the positioning block 51, the first positioning rod 53 and the second positioning rod 54 are both located in the avoidance groove, and the slide groove is flush with the matching groove 201. At this time, the limiting pin 521 extends into the matching groove 201 and is engaged with the matching groove 201, and the mounting seat 10 is located in front of the rotation direction of the turntable. The brake disc to be tested enters the testing platform 1 from the feeding mechanism 3 and falls on the positioning block 51, so that the brake disc is distributed obliquely, and the bottom end of the brake disc abuts against the testing disc 2. The first driving member drives the turntable to rotate, so that the testing disc 2 rotates around the circumference of the testing platform 1. Since the limiting pin 521 is engaged with the matching groove 201, the positioning disc 52 rotates synchronously with the testing disc 2. During this process, the second positioning rod 54 gradually approaches the inner hole wall of the brake disc and abuts against it. The second positioning rod 54 pushes the brake disc close to the positioning plate 56. When the brake disc abuts against the positioning plate 56, the testing disc 2 continues to rotate, which causes the first elastic member 55 to contract, and the second positioning rod 54 moves toward the circular direction of the positioning disc 52. When the second positioning rod 54 moves to the inner end of the slide groove, the second positioning rod 54 pushes the brake disc into the gap between the positioning plate 56 and the inner ring 101 or the outer ring 102, so that the brake disc is placed on the positioning disc 52. When the brake disc is flush with the positioning disc 52, the first positioning rod 53 is located in the inner hole of the brake disc, and the first elastic member 55 releases its elastic force and stretches, thereby pushing the second positioning rod 54 to move outward, so that the first positioning rod 53 and the second positioning rod 54 both stop against the inner hole wall of the brake disc, so that the brake disc and the positioning disc 52 are coaxially distributed, completing the positioning of the brake disc. At this time, the two detection heads 11 respectively stop against the upper surface and the lower surface of the brake disc.

[0046] The detection disk 2 passes through the first tooth groove 1021, and the positioning disk 52 meshes with the first tooth groove 1021, thereby rotating counterclockwise. At this time, the one-way bearing 14 and the positioning disk 52 rotate in coordination, and the positioning disk 52 drives the brake disk to rotate synchronously through the first positioning rod 53 and the second positioning rod 54. During the rotation process, the detection head 11 can detect the flatness of the corresponding position of the brake disk, and then the positioning disk 52 disengages from the first tooth groove 1021 and contacts with the second tooth groove 1011. Subsequently, the positioning disk 52 rotates clockwise. At this time, the one-way bearing 14 and the positioning disk 52 rotate synchronously, and the clamping block 131 is clamped in the clamping groove, and the one-way bearing 14 drives the coil 13 to rotate synchronously. The coil 13 presses the limit block 18 into the detection disk 2 during the rotation. When the coil 13 stops rotating, the limit block 18 extends into the limit groove 132 to prevent the coil 13 from rebounding. The coil 13 tightens the pull rope 17 during the rotation, thereby pushing the mounting seat 10 to overcome the elastic force of the second elastic member 12 and move inward. The second elastic member 12 contracts, and the two detection heads 11 move inward. Then the positioning disk 52 disengages from the second tooth groove 1011 and contacts the next first tooth groove 1021. The above detection process is repeated to realize flatness detection of different positions of the brake disc.

[0047] The brake disc gradually approaches the separation block 6, and the separation block 6 contacts the bottom end of the brake disc and pushes the brake disc to move upward. The brake disc is separated from the positioning disc 52 and is located in the discharge channel. The second driving member 9 drives the dial plate 8 to rotate, thereby shifting the brake disc to the discharge mechanism 4. When the brake disc is separated from the positioning disc 52, the bottom end of the mounting ring 15 abuts against the reset block 19, and the reset block 19 pushes the mounting ring 15 to move upward. The third elastic member 16 stretches, and the mounting ring 15 drives the coil 13 to move upward, so that the clamping block 131 is out of contact with the clamping groove. At this time, the second elastic member 12 contracts and pulls the mounting seat 10 outward to the outer end of the matching groove 201. The mounting seat 10 pulls the coil 13 to rotate through the pull rope 17. The coil 13 releases the pull rope 17 during the rotation process. When the mounting ring 15 passes the reset block 19, the third elastic member 16 contracts, thereby pulling the mounting ring 15 to move downward and reset. The mounting ring 15 drives the coil 13 to move downward, so that the clamping block 131 extends into the clamping groove. After the testing plate 2 moves around the testing platform 1 for one circle, the limiting pin 521 will re-enter the matching groove 201, and the testing plate 2 is now completely reset.
