Description

Technical Field

[0001] The present invention relates to the technical field of brake measurement, and in particular to a measuring tool for the outer diameter of a brake. Background Art

[0002] As a key component of a vehicle braking system, a brake mainly includes components such as a brake disc, a brake caliper, and brake pads. The brake disc is an important component directly involved in braking friction. It is of great significance to accurately measure the outer diameter of the brake disc. On the one hand, the outer diameter size of the brake disc directly affects its matching accuracy with the brake caliper and brake pads. If the outer diameter size deviation is too large, it will lead to uneven distribution of friction force during braking, affecting the braking effect, and even causing problems such as braking jitter and abnormal noise, seriously threatening driving safety. On the other hand, different vehicle models have specific specification requirements for the outer diameter of the brake disc. Accurately measuring the outer diameter helps to ensure that the brake disc meets the vehicle design standards and guarantees the universality and interchangeability of the product.

[0003] Existing measuring tools for the outer diameter of brakes use manual measuring tools such as calipers and micrometers. Although the operation is relatively simple, the measuring efficiency is low, making it difficult to meet the requirements of rapid detection on a large-scale production line. Moreover, during the manual measurement process, differences in the operation methods and forces of the measuring personnel will introduce large human errors, making it difficult to ensure the accuracy and consistency of the measurement results. In addition, most of the existing measuring tools can only measure a single brake disc and cannot achieve simultaneous detection of multiple brake discs, showing obvious shortcomings in terms of production efficiency.

[0020] The measuring component 6 includes a distance sensor one 61, a distance sensor two 62, a distance sensor three 63, and a distance sensor four 64 respectively arranged at one ends of the four groups of extension plates 55.

[0021] The inner support structure 7 includes a gear set arranged at one end of the bidirectional motor 3. On one side of the gear set, there are multiple expansion plates 76 evenly distributed. The multiple expansion plates 76 are used to fix the brake disc. The inner support structure 7 includes circular shells 71 rotatably connected to both sides of the bidirectional motor 3.

Compared with the traditional manual fixing method, it not only saves manpower but also ensures that the fixing force is consistent each time, guaranteeing the stability of the brake disc during the measurement process.

[0022] The driving component includes a support platform 2 arranged at the top end of the workbench 1. A bidirectional motor 3 is fixedly installed at the top end of the support platform 2, facilitating the driving component.

[0023] The linkage component 4 includes a main gear disc 42 fixedly connected to the output end of the bidirectional motor 3. An outer shell 41 is arranged at the top end of the workbench 1. The output end of the bidirectional motor 3 penetrates through the surface of the outer shell 41. The linkage component 4 also includes a channel 45 formed on the surface of the workbench 1. A driven rod 44 is rotatably connected inside the channel 45. A first gear 43 is arranged on the outer side of the driven rod 44. The first gear 43 is meshed with the main gear disc 42, facilitating the driving of the feeding structure 8.

[0024] The feeding structure 8 includes a screw rod 81 arranged at one end of the driven rod 44. The screw rod 81 is rotatably connected to the inner wall of the channel 45. A chute 85 is formed inside the workbench 1. A bottom block 84 is slidably connected inside the chute 85. A moving block 82 is arranged on one side of the bottom block 84. The moving block 82 is threadedly connected to the screw rod 81. A feeding table 83 is arranged at the top end of the moving block 82. Four card slots 831 are formed on the top surface of the feeding table 83. Two notches 832 are formed on both sides of the feeding table 83. Utilizing the speed difference of gear transmission, the feeding table 83 quickly feeds the brake disc into the measurement area, saving the preparation time before measurement.

[0025] The steering structure 9 includes an embedding groove 93 formed inside the moving block 82. A rotating column 91 is rotatably connected inside the embedding groove 93. The top end of the rotating column 91 is connected to the feeding table 83. A third gear 92 is arranged on the outer side of the rotating column 91. The steering structure 9 also includes a fixing plate 94 arranged at the top end of the workbench 1. An electric push rod 95 is arranged on one side of the fixing plate 94. A second rack 96 is arranged at the output end of the electric push rod 95. The second rack 96 is meshed with the third gear 92, facilitating the measurement of the outer diameters of the other two brake discs. The rotatable structural design of the feeding table 83 realizes the measurement of multiple brake discs with one loading, greatly improving the measurement efficiency.

[0026] Specifically, during use, manipulator components are arranged on both sides of the workbench 1. The manipulator components are used for feeding the brake discs. The manipulator places the clamped brake discs into the material clamping grooves 831 formed on the surface of the feeding table 83. Then, the bidirectional motor 3 is started. The bidirectional motor 3 is fixed on the support table 2, and the bottom end of the support table 2 is fixedly installed with the workbench 1, realizing the automatic docking of the brake disc feeding, reducing manual intervention, improving the feeding efficiency, and being uniformly driven by the bidirectional motor 3, ensuring the stability and synchronism of the structure operation; The bidirectional motor 3 drives the output ends on both sides to rotate forward. The bidirectional motor 3 is rotatably connected to the outer shell 41, so that the bidirectional motor 3 drives the main gear discs 42 on both sides to be meshed and rotated with the first gear 43. The first gear 43 drives the driven rod 44 to rotate. The driven rod 44 is rotatably connected to the groove 45 formed on the surface of the workbench 1. The driven rod 44 drives the screw rod 81 to rotate. One end of the screw rod 81 is rotatably connected to the groove 45. The screw rod 81 is threadedly connected to the moving block 82. The rotation of the screw rod 81 causes the moving block 82 to drive the feeding table 83 to move towards one side of the workbench 1, approaching the manipulator for feeding. The moving block 82 drives the bottom block 84 at the bottom end to slide in the sliding groove 85, which can convert the rotational motion of the bidirectional motor 3 into the linear motion of the feeding table 83, and ensure the smoothness and accuracy of the movement of the feeding table 83 by the cooperation of the sliding groove 85 and the bottom block 84, providing a stable basis for subsequent feeding and measurement; Then, the manipulator feeds and clamps the brake discs into the material clamping grooves 831 through the command program. Four groups of material clamping grooves 831 are arranged at equal intervals. When placing, the two groups of brake discs in the material clamping grooves 831 close to the manipulator are symmetrically placed with the other two groups, facilitating the subsequent turning of the feeding table 83 to measure the outer diameters of the other two groups of brake discs, making full use of the space of the feeding table 83, enabling multiple brake discs to be fed at one time, and at the same time facilitating the subsequent rotation to measure the brake discs at different positions, improving the overall measurement efficiency; At the same time, the bidirectional motor 3 drives the rotating disc 51 to rotate, causing the four arc-shaped grooves 52 on the surface of the rotating disc 51 to rotate. Then, the four sliding blocks 53 corresponding to the inside of the arc-shaped grooves 52 slide from one end of the arc-shaped groove 52 close to the center of the rotating disc 51 to the other end. The sliding block 53 drives the linear sliding plate 54 on one side to slide outward from the opening groove 57 correspondingly formed on the surface of the cross disc 56. The linear sliding plate 54 drives the distance sensor four 64 at one end of the extension plate 55 to move outward, increasing the distance between the distance sensors four 64, facilitating the brake discs on the feeding table 83 to enter the detection area between the distance sensors four 64, automatically adjusting the position of the distance sensors, making room for the brake discs to enter the detection area, avoiding interference, and ensuring the smooth progress of the feeding process; Moreover, the rotation of the bidirectional motor 3 drives the sun gear 72 to rotate forward and engage with the second gear 73. The second gear 73 drives the connecting rod 74 to rotate. The connecting rod 74 is rotationally connected to the circular shell 71, and the circular shell 71 is rotationally connected to the bidirectional motor 3. The second gear 73 engages with the first rack 75, and the first rack 75 moves towards the inside of the circular shell 71. The first rack 75 is slidably connected to the slot 77 correspondingly opened on the surface of the circular shell 71. Thus, the first rack 75 drives the expansion plate 76 to move towards the circular shell 71, reducing the overall volume and preventing the multiple expanded expansion plates 76 from blocking the movement of the brake disc into the measurement area. The inner support structure 7 automatically contracts when the brake disc has not entered, effectively avoiding blocking the movement of the brake disc, ensuring that the brake disc can smoothly reach the measurement area, and improving the smoothness of the equipment operation; After the four material clamping grooves 831 on the feeding table 83 are loaded, the bidirectional motor 3 is driven to reverse. When the bidirectional motor 3 reverses, it will drive the main gear disk 42 to reversely engage with the first gear 43. The main gear disk 42 drives the driven rod 44 to reverse. Since the main gear disk 42 rotates one circle and drives the first gear 43 to rotate multiple circles, the rotation speed of the screw rod 81 on one side of the driven rod 44 driven by the first gear 43 is fast. Furthermore, the screw rod 81 is reversely threadedly connected to the moving block 82, so that the moving block 82 drives the feeding table 83 to quickly move towards the fourth distance sensor 64. The feeding table 83 at the bottom of the moving block 82 quickly slides in the sliding groove 85 towards the fourth distance sensor 64. The feeding table 83 facilitates feeding the brake disc into the measurement area between the fourth distance sensor 64. By using the speed difference of gear transmission, the feeding table 83 quickly feeds the brake disc into the measurement area, saving the preparation time before measurement and improving the overall measurement efficiency; Moreover, the rotation of the bidirectional motor 3 drives the sun gear 72 to rotate reversely and engage with the second gear 73. The second gear 73 drives the connecting rod 74 to rotate. The connecting rod 74 is rotationally connected to the circular shell 71, and the circular shell 71 is rotationally connected to the bidirectional motor 3. The second gear 73 engages with the first rack 75, and the first rack 75 moves towards the outside of the circular shell 71. The first rack 75 is slidably connected to the slot 77 correspondingly opened on the surface of the circular shell 71. Thus, the first rack 75 drives the expansion plate 76 to move towards the outside of the circular shell 71 to fix the brake disc. Compared with the traditional manual fixing method, it not only saves manpower but also ensures that the fixing force is consistent each time, guarantees the stability of the brake disc during measurement, avoids measurement errors caused by insecure fixing, is applicable to the measurement of brake discs of various specifications and sizes, and greatly improves the versatility and application range of the measuring tooling; At the same time, the reverse rotation of the rotating disk 51 drives the sliding block 53 in the arc-shaped groove 52, so that the sliding block 53 slides from one end of the arc-shaped groove 52 away from the center of the rotating disk 51 to the other end, causing the sliding block 53 to drive the linear slide plate 54 at one end to slide towards the cross disk 56 in the opening groove 57. Furthermore, the linear slide plate 54 drives the extension plate 55 at one end to approach the outside of the brake disk. Since there are four groups of sliding blocks 53, there are also four groups of corresponding linear slide plates 54 and extension plates 55. And there is an extension plate 55 corresponding to each of the four groups of linear slide plates 54. The four extension plates 55 are respectively fixedly installed with a distance sensor one 61, a distance sensor two 62, a distance sensor three 63, and a distance sensor four 64. The distance sensor one 61 and the distance sensor two 62 are symmetrically distributed up and down, and the distance sensor three 63 and the distance sensor four 64 are symmetrically distributed left and right. The length of the extension plate 55 connected to the distance sensor one 61 and the distance sensor two 62 is equal to half of the length of the extension plate 55 connected to the distance sensor three 63 and the distance sensor four 64, which is convenient for measuring the outer diameters of two brake disks simultaneously in sequence and improving the efficiency. Since notches 832 are provided on both sides of the feeding table 83, it is convenient for the distance sensor two 62 to contact the outer end of the bottom end of the brake disk clamped in the material clamping groove 831. Therefore, the distance sensor one 61 and the distance sensor two 62 measure the outer diameter of one group of brake disks, and the distance sensor three 63 and the distance sensor four 64 measure the other group of brake disks. Since there are four groups symmetrically clamped on the feeding table 83, after the distance sensor one 61 and the distance sensor two 62 as well as the distance sensor three 63 and the distance sensor four 64 complete the measurement of the outer diameters of two groups of brake disks simultaneously, the electric push rod 95 fixed to the top end of the workbench 1 by the fixing plate 94 is driven. The electric push rod 95 drives the rack two 96 at the output end to move, so that the rack two 96 is meshed and connected with the gear three 92. The gear three 92 drives the feeding table 83 at the top end of the rotating column 91 to rotate. The rotating column 91 is rotatably connected to the embedding groove 93 opened in the moving block 82, and the gear three 92 rotates in the embedding groove 93. The feeding table 83 rotates 360 degrees, causing the other two groups of brake disks on the feeding table 83 to rotate between the distance sensors, which is convenient for measuring the outer diameters of the other two groups of brake disks. The rotatable structural design of the feeding table 83 realizes the measurement of multiple brake disks with one loading, greatly improving the measurement efficiency and reducing operation steps such as repeated loading.
