Description

Technical Field

[0002] The brake disc is the braking system of a car. The more common brake devices are mainly of two types: "drum brakes" and "disc brakes". "Disc brakes" are sometimes also called "disc brakes", and one of the key components of "disc brakes" is the brake disc. Disc brakes use stationary brake pads to clamp the brake disc that rotates with the tire to generate friction, thereby reducing the rotation speed of the wheel. After the brake disc is processed, it needs to be measured for flatness and opening.

[0003] After the brake disc is produced, burrs and debris left over from drilling are easily left in the hole. When the diameter of the hole in the brake disc is detected, the burrs and debris not only affect the accuracy of the detection, but also when the measuring device and the hole in the brake disc are in contact and rubbed, the hole in the brake disc is easily scratched by the debris. The existing technology is not convenient for cleaning the burrs and debris in the hole in the brake disc, and when it is detected that the diameter of the hole in the brake disc is insufficient, it is not convenient to grind and expand it in time.

The gear 7 is meshed with a rack 8. A second motor 9 is fixedly connected to the inner wall of the processing table 5, and a measuring head 10 is fixedly connected to the output of the second motor 9. Four slide bars 22 are equidistantly slidably connected to the inner wall of the measuring head 10. An adjustment component used in conjunction with the slide bars 22 is provided on the inner wall of the measuring head 10. Pressure sensors 28 are provided on the inner walls of the four slide bars 22. The detection ends of the four pressure sensors 28 are fixedly connected with a protrusion 27. The protrusion 27 is slidably connected to the slide bar 22 and one end thereof extends to the outside of the slide bar 22. The outer wall of the pressure sensor 28 is sleeved with a third spring 26, one end of the third spring 26 is fixedly connected to the slide bar 22, and the other end of the third spring 26 is fixedly connected to the protrusion 27.

[0038] Through the above technical scheme, the brake disc is placed on the placement table 3, the fourth motor 53 is started, the bidirectional screw rod 54 is driven to rotate, the two movable blocks 55 are brought close to each other, and the two clamping blocks 56 are driven to approach each other. The brake disc is clamped and fixed by the two clamping blocks 56 to prevent displacement during the detection of the brake disc from affecting the accuracy of the detection. The four slide bars 22 are controlled to move by the adjustment component, so that the four slide bars 22 are opened and the protrusion 27 is driven to move to the standard position of the brake disc center hole. The first motor 6 is started to drive the gear 7 to rotate, so that the processing table 5 moves downward, and the measuring head 10 is driven to enter the center hole of the brake disc. The second motor 9 is started to drive the measuring head 10 to rotate, so that the four slide bars 22 rotate, and the four protrusions 27 are driven to rotate around the brake disc center hole. When the diameter of the brake disc center hole is insufficient or there is a protrusion inside, the protrusion 27 is squeezed and moves toward the inside of the slide bar 22, pressing the third spring 26. At this time, the pressure sensor 28 detects the pressure and displays the data to the detection personnel.

[0039] Specifically, the adjustment component includes a third motor 13, which is fixedly installed on the top of the inner wall of the measuring head 10, and the output end of the third motor 13 is fixedly connected to a reciprocating screw 14, and the outer wall of the reciprocating screw 14 is connected to a slider 15 through a screw nut pair, and the bottom of the slider 15 is symmetrically rotatably connected to four connecting shafts 21, and the four connecting shafts 21 are rotatably connected to four sliding rods 22 respectively, and the inner wall of the measuring head 10 and the bottom of the sliding rod 22 are fixedly connected to a fixed plate 12, and the four sliding rods 22 are all slidably connected to the fixed plate 12, and the inner wall of the fixed plate 12 is equidistantly fixedly connected to four sliding shafts 23, and the outer walls of the four sliding shafts 23 are all slidably connected to connecting blocks 25, and the four connecting blocks 25 are respectively fixedly connected to the four sliding rods 22, and the outer wall of the sliding shaft 23 is sleeved with a second spring 24, one end of the second spring 24 is fixedly connected to the fixed plate 12, and the other end of the second spring 24 is fixedly connected to the connecting block 25, and the inner wall of the measuring head 10 is set as a limit unit.

[0040] Through the above technical solution, the third motor 13 is started to drive the reciprocating screw 14 to rotate clockwise, and the slider 15 is moved up and down through the set limit unit. When the slider 15 moves downward, the four connecting shafts 21 are used to push the four slide bars 22 to move outward. When the four slide bars 22 move outward, the four connecting blocks 25 are driven to move outward, and the four second springs 24 are pressed. When the slider 15 moves upward, the four slide bars 22 are pulled by the four connecting shafts 21, and the four second springs 24 are used to drive the four slide bars 22 to move inward, thereby adjusting the positions of the four slide bars 22.

[0041] Specifically, the limiting unit includes a ring 17, which is slidably connected to the measuring head 10, and a connecting rod 16 is fixedly connected between the ring 17 and the slider 15. The inner wall of the ring 17 is symmetrically slidably connected with two first clamping blocks 18, one side of the two first clamping blocks 18 is fixedly connected with a first spring 19, and the two first springs 19 are fixedly connected to the ring 17. The other sides of the two first clamping blocks 18 are set to be inclined surfaces, and the inner wall of the measuring head 10 is symmetrically provided with two first limiting grooves 20, and the first clamping blocks 18 fit the inner wall of the first limiting grooves 20.

[0042] Through the above technical solution, the third motor 13 is started to drive the reciprocating screw 14 to rotate counterclockwise, so that the slider 15 rotates counterclockwise, the collar 17 rotates counterclockwise, and the first clamping block 18 rotates counterclockwise. When the first clamping block 18 rotates to the first limiting groove 20, under the action of the first spring 19, the first clamping block 18 enters the first limiting groove 20. As the reciprocating screw 14 continues to rotate, the inclined surface on one side of the first clamping block 18 presses against the first limiting groove 20. Under the extrusion of the first limiting groove 20, the first clamping block 18 moves into the collar 17 and presses the first spring 19, thereby When the reciprocating screw 14 rotates counterclockwise, it drives the slider 15 and the collar 17 to rotate counterclockwise, starts the third motor 13, drives the reciprocating screw 14 to rotate clockwise, makes the slider 15 rotate clockwise, drives the first block 18 to rotate clockwise, when the first block 18 rotates to the first limiting groove 20, under the action of the first spring 19, the first block 18 enters the collar 17, as the reciprocating screw 14 continues to rotate, the straight surface of one side of the first block 18 presses against the first limiting groove 20 and cannot rotate, thus when the reciprocating screw 14 rotates clockwise, it drives the slider 15 to move back and forth up and down.

[0043] Specifically, four fixing frames 57 are equidistantly fixedly connected to the bottom of the measuring head 10, the inner walls of the four fixing frames 57 are rotatably connected to rotating plates 58, the tops of the four rotating plates 58 are fixedly connected to rubber plates 60, the four rubber plates 60 are all installed at an angle, a spring sheet 59 is fixedly connected between the rotating plate 58 and the measuring head 10, and a plurality of sponges 61 are equidistantly fixedly connected to the outer walls of the rubber plates 60, and the outer walls of the sponges 61 are set as an inclined surface.

[0044] Through the above technical solution, when the measuring head 10 enters the middle hole of the brake disc, the bottoms of the four rubber plates 60 are pressed against the middle hole of the brake disc. As the measuring head 10 moves downward, the four rubber plates 60 are squeezed by the middle hole of the brake disc, and the four spring plates 59 are pressed. Under the reaction of the four spring plates 59, the four rubber plates 60 are pressed against the inner wall of the middle hole of the brake disc at the same time. The second motor 9 is started to drive the measuring head 10 to rotate, so that the four rubber plates 60 rotate at the same time. By using the sponge wiper 61 set on the rubber plate 60, the burrs and debris in the middle hole of the brake disc can be effectively removed.

[0045] Specifically, the bottoms of the four sliding rods 22 are fixedly connected with grinding discs 29, the bottoms of the four grinding discs 29 are all set as inclined surfaces, the outer walls of the grinding discs 29 are provided with grooves 30, the inner wall of the measuring head 10 is fixedly connected with a partition 11 below the fixed plate 12, and a loading assembly is provided on the top of the partition 11.

[0046] Through the above technical scheme, grinding paste is loaded inside the measuring head 10 and at the bottom of the partition 11. When the pressure sensor 28 detects pressure, the third motor 13 continues to control the four slide bars 22 to extend outward. Under the extrusion of the hole in the brake disc, the four protrusions 27 enter the four slide bars 22 respectively, and the four third springs 26 are pressed. After the four protrusions 27 enter the four slide bars 22 respectively, the ends of the four slide bars 22 are simultaneously pressed against the middle hole of the brake disc, so that the four grinding discs 29 are simultaneously pressed against the middle hole of the brake disc, and the second motor 9 is started to drive the measuring head 10 to rotate, so that the four grinding discs 29 rotate at the same time, thereby grinding the middle hole of the brake disc and continuously expanding the inner diameter of the hole in the brake disc. When the pressure sensor 28 cannot detect the pressure, it means that the inner diameter of the hole in the brake disc meets the standard. When the second motor 9 drives the four grinding discs 29 to rotate to grind the hole in the brake disc, grinding paste is added to the four grinding discs 29 through the feeding assembly, thereby improving the smoothness of the hole in the brake disc after grinding.

[0047] Specifically, the feeding assembly includes a first set box 31, the first set box 31 is fixedly installed on the inner wall of the partition 11, the top of the first set box 31 is fixedly connected to the second set box 32, the inner wall of the second set box 32 is slidably connected to the push rod 33, the bottom of the push rod 33 extends to the inside of the first set box 31 and is fixedly connected to a piston plate 36, the piston plate 36 fits the inner wall of the first set box 31, the outer wall of the push rod 33 is fixedly connected to the limiting plate 34, the outer wall of the push rod 33 is sleeved with a fourth spring 35, the top of the fourth spring 35 is fixedly connected to the limiting plate 34, the bottom of the fourth spring 35 is fixedly connected to the first set box 31, and the first set box 3 1 is fixedly connected to the bottom of the measuring head 10, and a first one-way valve 38 is provided on the inner wall of the liquid extraction pipeline 37, and the first one-way valve 38 is opened toward the first set box 31.

One end of the liquid outlet pipeline 39 passes through the measuring head 10 and is fixedly connected to a hose 41, and one end of the hose 41 extends to the inside of the groove 30. The top of the push rod 33 passes through the second set box 32, and a driving assembly is provided at the bottom of the reciprocating screw rod 14.

[0048] Through the above technical solution, the third motor 13 is started to drive the reciprocating screw rod 14 to rotate counterclockwise, and the push rod 33 is moved back and forth up and down through the driving assembly in cooperation with the fourth spring 35. When the push rod 33 moves upward, it drives the piston plate 36 to move upward. Under the pulling action of the piston plate 36, the first one-way valve 38 and the second one-way valve 40 are cooperated to make the polishing paste at the bottom of the partition 11 be drawn into the first set of boxes 31 along the liquid extraction pipe 37. When the push rod 33 moves downward, it drives the piston plate 36 to move downward. Under the cooperation of the first one-way valve 38 and the second one-way valve 40, the polishing paste in the first set of boxes 31 is squeezed out along the four liquid outlet pipes 39, and the polishing paste enters the groove 30 along the hose 41, thereby adding polishing paste to the fitting part between the grinding disc 29 and the hole in the brake disc.

[0049] Specifically, the driving assembly includes a turntable 46 fixedly connected to the lower end of the reciprocating screw rod 14, and two top blocks 47 are symmetrically fixedly connected to the bottom of the turntable 46. One side of the two top blocks 47 is set as an inclined surface, and the outer wall of the top rod 33 is rotatably connected to the rotating rod 42, and the inner wall of the rotating rod 42 is provided with a linkage unit.

[0050] Through the above technical solution, the third motor 13 is started to drive the reciprocating screw 14 to rotate counterclockwise, causing the two top blocks 47 to rotate counterclockwise. When the two top blocks 47 rotate to the position of the rotating rod 42, under the extrusion of the inclined surfaces of the two top blocks 47, the linkage unit is cooperated to push the rotating rod 42 to move downward, driving the top rod 33 to move downward, and compressing the fourth spring 35. When the two top blocks 47 are separated from the rotating rod 42, under the action of the fourth spring 35, the top rod 33 moves upward, thereby reciprocating. While the reciprocating screw 14 rotates counterclockwise, it drives the top rod 33 to move reciprocatingly up and down.

[0051] Specifically, the linkage unit includes two second clamping blocks 44, both of which are arranged inside the rotating rod 42 and are symmetrically installed, and both of which are slidingly connected to the rotating rod 42. One end of the second clamping block 44 is set as an inclined surface, and the other end of the second clamping block 44 is fixedly connected with a fifth spring 43, and the fifth spring 43 is fixedly connected to the rotating rod 42. The outer wall of the top rod 33 is symmetrically provided with two second limiting grooves 45, and the second clamping blocks 44 fit the inner wall of the second limiting grooves 45, and the elastic force of the fourth spring 35 is greater than the elastic force of the fifth spring 43.

[0052] By means of the above technical scheme, when the reciprocating screw 14 rotates counterclockwise, the two top blocks 47 rotate counterclockwise. When the two top blocks 47 rotate to the position of the rotating rod 42, under the extrusion of the inclined surfaces of the two top blocks 47, the straight surface of one side of the second clamping block 44 is pressed against the second limiting groove 45. Through the limitation of the second clamping block 44, the rotating rod 42 moves downward under the extrusion of the inclined surface of the top block 44. When the reciprocating screw 14 rotates clockwise, the two top blocks 47 rotate clockwise. When the two top blocks 47 rotate to the position of the rotating rod 42, under the pushing action of the straight surfaces of the two top blocks 47, the inclined surface of one side of the second clamping block 44 is pressed against the second limiting groove 45. Through the extrusion of the second limiting groove 45, the second clamping block 44 moves toward the inside of the rotating rod 42, compressing the fourth spring 35, thereby driving the rotating rod 42 to rotate on the top rod 33 as the top block 47 rotates clockwise.

[0054] Through the above technical solution, the exhaust fan 50 is started, and the burrs and debris falling from the brake disc can be sucked into the storage chamber 49 along the feed port 48, and the burrs and debris are filtered through the filter screen 52, so that the burrs and debris remain on the filter screen 52, and the excess gas is discharged from the placement table 3 along the exhaust duct 51.

[0055] A detection method for a brake disc hole detection device, the detection method is applicable to the above-mentioned brake disc hole detection device, the detection method steps are as follows:

[0056] S1: Place the brake disc on the placement table 3, start the fourth motor 53 to control the two clamping blocks 56 to move closer to each other, clamp and fix the brake disc, start the third motor 13 to control the four protrusions 27 to move to the standard position of the center hole of the brake disc, start the first motor 6 to control the processing table 5 to move downward, and drive the measuring head 10 to enter the center hole of the brake disc;

[0057] S2: Start the second motor 9 to drive the measuring head 10 to rotate. When the pressure sensor 28 detects the pressure, the data is displayed to the inspector;

[0058] S3: Start the third motor 13 to control the four grinding discs 29 to press against the middle hole of the brake disc, start the second motor 9 to control the four grinding discs 29 to grind the middle hole of the brake disc, and start the third motor 13 to control the intermittent and quantitative application of polishing paste on the joint between the grinding disc 29 and the middle hole of the brake disc.

[0059] When in use, the brake disc is placed on the placement table 3, and the fourth motor 53 is started to drive the bidirectional screw rod 54 to rotate, so that the two movable blocks 55 are close to each other, and the two clamping blocks 56 are driven to approach each other. The brake disc is clamped and fixed by the two clamping blocks 56 to prevent displacement during the detection of the brake disc and affect the accuracy of the detection. The third motor 13 is started to drive the reciprocating screw rod 14 to rotate clockwise, so that the slider 15 rotates clockwise, and the first clamping block 18 rotates clockwise. When the first clamping block 18 rotates to the first limiting groove 20, under the action of the first spring 19, the first clamping block 18 enters the collar 17. As the reciprocating screw rod 14 continues to rotate, the straight surface on one side of the first clamping block 18 presses against the first limiting groove 20 and cannot rotate, thereby the reciprocating screw rod 14 rotates clockwise. When rotating, the slider 15 is driven to move up and down reciprocatingly. When the reciprocating screw rod 14 rotates clockwise, the two top blocks 47 are rotated clockwise. When the two top blocks 47 rotate to the position of the rotating rod 42, the inclined surface of one side of the second clamping block 44 is pressed against the second limiting groove 45 under the pushing action of the two top blocks 47. Through the extrusion of the second limiting groove 45, the second clamping block 44 moves toward the inside of the rotating rod 42 and presses the fourth spring 35. As a result, as the top block 47 rotates clockwise, the rotating rod 42 is driven to rotate on the top rod 33. When the slider 15 moves downward, the four sliding rods 22 are pushed outward through the four connecting shafts 21. When the four sliding rods 22 move outward, the four connecting blocks 25 are driven to move outward and press the four second springs 24. When the slider 1 When the measuring head 10 moves upward, the four connecting shafts 21 pull the four slide bars 22, and cooperate with the four second springs 24 to drive the four slide bars 22 to move inward, thereby adjusting the positions of the four slide bars 22 and driving the protrusion 27 to move to the standard position of the center hole of the brake disc, starting the first motor 6, driving the gear 7 to rotate, so that the processing table 5 moves downward, driving the measuring head 10 to enter the center hole of the brake disc, when the measuring head 10 enters the center hole of the brake disc, the bottoms of the four rubber plates 60 are pressed against the center hole of the brake disc, as the measuring head 10 moves downward, under the extrusion of the center hole of the brake disc, the four rubber plates 60 rotate upward at the same time, pressing the four spring plates 59, and under the reaction of the four spring plates 59, the four rubber plates 60 are pressed against the center hole of the brake disc at the same time. The inner wall of the brake disc is started, the second motor 9 is started, and the measuring head 10 is driven to rotate, so that the four rubber plates 60 are rotated at the same time. The sponge wiper 61 provided on the rubber plate 60 can effectively remove the burrs and debris in the hole of the brake disc. The exhaust fan 50 is started, and the burrs and debris falling from the brake disc can be sucked into the storage chamber 49 along the feed port 48. The burrs and debris are filtered through the filter screen 52, so that the burrs and debris remain on the filter screen 52, and the excess gas is discharged from the placement table 3 along the exhaust duct 51. When the second motor 9 is started, the measuring head 10 is driven to rotate, the four slide bars 22 are rotated, and the four protrusions 27 are driven to rotate around the hole in the brake disc. When the diameter of the hole in the brake disc is insufficient or there is a protrusion inside, the protrusion 27 is squeezed and moves toward the inside of the slide bar 22.The third spring 26 is compressed. At this time, the pressure sensor 28 detects the pressure and displays the data to the inspector. The grinding paste is loaded inside the measuring head 10 and at the bottom of the partition 11. When the pressure sensor 28 detects the pressure, the third motor 13 continues to control the four slide bars 22 to extend outward. Under the squeezing of the center hole of the brake disc, the four protrusions 27 enter the four slide bars 22 respectively, and the four third springs 26 are compressed. After the four protrusions 27 enter the four slide bars 22 respectively, the ends of the four slide bars 22 are pressed against the center hole of the brake disc at the same time, so that the four grinding discs 29 are pressed against the center hole of the brake disc at the same time, and the second motor 9 is started to drive the measuring head 10 to rotate, so that the four grinding discs 29 rotate at the same time, thereby the center hole of the brake disc is adjusted. Grinding, and continuously expanding the inner diameter of the hole in the brake disc. When the pressure sensor 28 detects no pressure, it means that the inner diameter of the hole in the brake disc meets the standard. When the second motor 9 drives the four grinding discs 29 to rotate and grind the hole in the brake disc, the third motor 13 is started to drive the reciprocating screw 14 to rotate counterclockwise, so that the slider 15 rotates counterclockwise, the collar 17 rotates counterclockwise, and drives the first clamping block 18 to rotate counterclockwise. When the first clamping block 18 rotates to the first limiting groove 20, under the action of the first spring 19, the first clamping block 18 enters the first limiting groove 20. As the reciprocating screw 14 continues to rotate, the inclined surface on one side of the first clamping block 18 presses against the first limiting groove 20. Under the extrusion of the first limiting groove 20, the first clamping block 18 moves into the sleeve ring 17, compressing the first spring 19, thereby when the reciprocating screw rod 14 rotates counterclockwise, the slider 15 and the sleeve ring 17 rotate counterclockwise, and the reciprocating screw rod 14 rotates counterclockwise while the two top blocks 47 rotate counterclockwise. When the two top blocks 47 rotate to the position of the rotating rod 42, under the extrusion of the inclined surfaces of the two top blocks 47, the straight surface of one side of the second clamping block 44 is pressed against the second limiting groove 45. Through the limitation of the second clamping block 44, the rotating rod 42 moves downward under the extrusion of the inclined surface of the top block 47. The downward movement of the rotating rod 42 drives the top rod 33 to move downward, compressing the fourth spring 35. When the two top blocks 47 are separated from the rotating rod 42, under the action of the fourth spring 35, the top rod 33 moves upward, thereby the reciprocating screw rod 14 rotates counterclockwise. , while the reciprocating screw rod 14 rotates counterclockwise, it drives the push rod 33 to move up and down reciprocatingly. When the push rod 33 moves upward, it drives the piston plate 36 to move upward. Under the pulling action of the piston plate 36, the first one-way valve 38 and the second one-way valve 40 are cooperated to make the polishing paste at the bottom of the partition 11 be drawn into the first set box 31 along the liquid extraction pipe 37. When the push rod 33 moves downward, it drives the piston plate 36 to move downward. Under the cooperation of the first one-way valve 38 and the second one-way valve 40, the polishing paste in the first set box 31 is squeezed out along the four liquid outlet pipes 39, and the polishing paste enters the groove 30 along the hose 41, thereby adding polishing paste to the joint between the grinding disc 29 and the hole in the brake disc, thereby improving the smoothness of the hole in the brake disc after grinding. ,
