Description
Technical Field
[0001] This utility model relates to the technical field of brake disc drilling equipment, and in particular to a brake disc drilling equipment with an anti-breakage drill bit. Background Technology
[0002] In the automotive manufacturing and repair industry, brake discs are key braking components, and their processing quality directly affects driving safety. Drilling is an important process in brake disc production. By opening heat dissipation holes and weight reduction holes on the surface of the brake disc, heat dissipation performance can be effectively improved and weight can be reduced.
[0003] Currently, brake disc drilling equipment mostly uses high-speed rotating drill bits for processing. At the moment the drill bit contacts the workpiece, vibration will cause the local stress to increase instantaneously. When it exceeds the bearing limit of the drill bit material, microcracks will be generated in these stress concentration areas. As cutting continues, the microcracks gradually expand, eventually leading to the drill bit chipping. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-breakage drill bit type brake disc drilling device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drill bit anti-breakage type brake disc drilling device, comprising an operating table, two rectangular plates slidably connected to the operating table, a mounting frame slidably connected to the two rectangular plates, a device block slidably connected to the mounting frame, a second motor fixedly connected to the device block, a mounting block rotatably connected to the device block, a drill bit detachably mounted on the mounting block, the mounting block being driven to rotate by the second motor, screws rotatably connected to the operating table and rectangular plates respectively, one screw threaded to one rectangular plate, and one screw threaded to the mounting frame, a first motor fixedly connected to the operating table and one rectangular plate respectively, the screws being driven to rotate by the first motor, an anti-breakage structure provided on the mounting block, the anti-breakage structure mainly composed of ring blocks, the ring blocks being fixedly connected to the device block, three first springs fixedly connected to the inner wall of the ring blocks, a clamping block fixedly connected to one end of each first spring, and a soft pad fixedly connected to the clamping block.
[0006] The aforementioned components achieve the following effects: The brake disc is mounted on the operating table. The output of the second motor (SM3500) is connected to the mounting block via a reducer and coupling. First, the power is switched on to power the second motor control system. Starting the second motor then drives the mounting block to rotate, which in turn drives the drill bit to rotate. The first motor (17HS4401) drives the screw to rotate, allowing adjustment of the drill bit's position. During drilling, the drill bit vibrates, acting on the three clamping blocks. This causes the soft pads and the first spring to deform and absorb some energy, reducing damage to the drill bit. This avoids the situation where, at the moment of contact between the drill bit and the workpiece, vibration causes a sudden increase in local stress, exceeding the drill bit material's tolerance limit. In such cases, microcracks would form at these stress concentration points, gradually expanding as cutting continues, eventually leading to drill bit chipping.
[0007] Preferably, three damping rods are fixedly connected to the ring block, one end of each damping rod is fixedly connected to the clamping block, and the first spring is sleeved on the damping rod.
[0008] The effect achieved by the above components is as follows: the first spring immediately returns to its original position and releases the absorbed energy, and the damping rod converts it into heat energy through internal friction, thereby reducing the duration and amplitude of continuous vibration.
[0009] Preferably, a protective cover is rotatably connected to the mounting block, a sliding cover is slidably connected to the protective cover, and a rubber block is fixedly connected to one end of the sliding cover.
[0010] The aforementioned components achieve the following effects: when the drill bit is not in use, the protective cover and sliding cover cover the outside of the drill bit to protect it; when the drill bit descends to work, the rubber block abuts against the surface of the brake disc, and the sliding cover slides upward to prevent debris from flying.
[0011] Preferably, the outer wall of the protective cover has two sliding grooves, and the inner wall of the sliding cover has two sliders fixedly connected, with the sliding grooves and sliders slidably connected.
[0012] The effect achieved by the above components is that the slider slides in the groove, making the movement of the sliding cover more stable.
[0013] Preferably, a second spring is fixedly connected to the slider, and one end of the second spring is fixedly connected to the inner wall of the groove.
[0014] The effect achieved by the above components is as follows: after the rubber block abuts against the brake disc, as the drill bit continues to descend, the second spring gradually contracts, so the rebound force of the second spring acts on the slider, making the limit more stable.
[0015] Preferably, the operating table is provided with an installation structure, which mainly consists of four sliding grooves. All four sliding grooves are opened on the operating table. Sliding blocks are slidably connected in the sliding grooves. An installation plate is fixedly connected to the sliding block. A rubber pad is fixedly connected to the installation plate.
[0016] The effect achieved by the above components is as follows: the brake disc is placed on the operating table, and then the sliding block is slid so that the four mounting plates abut against the inner wall of the brake disc, which facilitates the limiting installation of the brake disc. The rubber pad can increase friction to improve the limiting effect.
[0017] Preferably, a sleeve is provided on the operating table, and four connecting rods are rotatably connected to the sliding block, with the connecting rods rotatably connected to the sleeve.
[0018] The effect achieved by the above components is that the up-and-down movement of the sleeve can drive the connecting rod to move, which in turn drives the four sliding blocks to move synchronously, making the operation more convenient.
[0019] Preferably, a threaded rod is rotatably connected to the operating table via a bearing, the threaded rod is threadedly connected to a sleeve, and a third motor is fixedly connected to the operating table, the threaded rod being driven to rotate by the third motor.
[0020] The effect achieved by the above components is as follows: the output end of the third motor is connected to the threaded rod through a reducer and a coupling. The motor model is 17HS4401. First, the power is turned on to power the third motor control system. Then, the third motor is started to drive the threaded rod to rotate, which in turn drives the sleeve to move up and down.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting an anti-breakage structure, the brake disc is installed on the operating table. The output end of the second motor is connected to the mounting block through a reducer and a coupling. The motor model is SM3500. First, the power is turned on to power the second motor control system. Then, starting the second motor can drive the mounting block to rotate, which in turn drives the drill bit to rotate. The first motor model is 17HS4401. Starting the first motor can drive the screw to rotate, which can adjust the position of the drill bit. During the drilling process, the drill bit vibrates, which acts on the three clamping blocks, causing the soft pad and the first spring to deform and absorb some energy, thereby reducing damage to the drill bit. This avoids the situation where, at the moment of contact between the drill bit and the workpiece, the vibration causes a sudden increase in local stress, which exceeds the bearing limit of the drill bit material. When this occurs, microcracks will form at these stress concentration points. As cutting continues, the microcracks gradually expand, eventually leading to the drill bit breaking.

Detailed Implementation
[0028] Example 1, such as Figure 1 and Figure 3 As shown, a type 11 anti-breakage drill bit brake disc drilling device includes an operating table 1. Two rectangular plates 2 are slidably connected to the operating table 1. A mounting frame 3 is slidably connected to both rectangular plates 2. An equipment block 4 is slidably connected to the mounting frame 3. A second motor 7 is fixedly connected to the equipment block 4. An installation block 10 is rotatably connected to the equipment block 4. A drill bit 11 is detachably installed on the installation block 10. The installation block 10 is driven to rotate by the second motor 7. Screws 5 are rotatably connected to the operating table 1 and the rectangular plates 2 respectively. One screw 5 is threadedly connected to one rectangular plate 2, and another screw 5 is threadedly connected to the mounting frame 3. A first motor 6 is fixedly connected to the operating table 1 and one rectangular plate 2 respectively. The screws 5 are driven to rotate by the first motor 6.
[0029] Reference Figures 2 to 4The mounting block 10 is equipped with an anti-collision structure 8, which mainly consists of a ring block 81. The ring block 81 is fixedly connected to the equipment block 4. Three first springs 82 are fixedly connected to the inner wall of the ring block 81. One end of the first spring 82 is fixedly connected to a clamping block 83. A soft pad 85 is fixedly connected to the clamping block 83. The brake disc is mounted on the operating table 1. The output end of the second motor 7 is connected to the mounting block 10 through a reducer and a coupling. The motor model is SM3500. First, the power is turned on to power the control system of the second motor 7. Then, the second motor 7 is started, which can drive the mounting block 10 to rotate, thereby driving the drill bit 11 to rotate. The first motor 6 is of type The drill bit 11, designated 17HS4401, is activated by starting the first motor 6, which drives the screw 5 to rotate, thereby adjusting the position of the drill bit 11. During drilling, the drill bit 11 vibrates, acting on the three clamping blocks 83. This causes the soft pad 85 and the first spring 82 to deform and absorb some energy, reducing damage to the drill bit 11. This prevents the local stress from increasing instantaneously at the moment of contact between the drill bit 11 and the workpiece, exceeding the material's tolerance limit. In such cases, microcracks would form at these stress concentration points, gradually expanding as cutting continues, eventually leading to the drill bit 11 chipping. Three damping blocks are fixedly connected to the ring block 81. Rod 84, one end of which is fixedly connected to clamping block 83. First spring 82 is sleeved on damping rod 84. First spring 82 then returns to its original position, releasing the absorbed energy. Damping rod 84 converts the energy into heat energy through internal friction, thereby reducing the duration and amplitude of continuous vibration. Protective cover 86 is rotatably connected to mounting block 10. Sliding cover 87 is slidably connected to protective cover 86. Rubber block 88 is fixedly connected to one end of sliding cover 87. When drill bit 11 is not in use, protective cover 86 and sliding cover 87 cover the outside of drill bit 11, which can protect drill bit 11. When drill bit 11 descends for operation, rubber block 88 abuts against the surface of brake disc and slides. The cover 87 slides upwards, which can also prevent debris from flying. Two grooves 89 are opened on the outer wall of the protective cover 86. Two sliders 810 are fixedly connected to the inner wall of the sliding cover 87. The grooves 89 and the sliders 810 are slidably connected. The sliders 810 slide in the grooves 89, making the movement of the sliding cover 87 more stable. A second spring 811 is fixedly connected to the slider 810. One end of the second spring 811 is fixedly connected to the inner wall of the groove 89. After the rubber block 88 abuts against the brake disc, as the drill bit 11 continues to descend, the second spring 811 gradually contracts. Therefore, the rebound force of the second spring 811 acts on the slider 810, making the limit more stable.
[0030] Reference Figure 2 and Figure 5The operating platform 1 is equipped with an installation structure 9, which mainly consists of four sliding grooves 91. Each of the four sliding grooves 91 is located on the operating platform 1. Sliding blocks 92 are slidably connected to the sliding grooves 91. Mounting plates 93 are fixedly connected to the sliding blocks 92, and rubber pads 94 are fixedly connected to the mounting plates 93. When the brake disc is placed on the operating platform 1, the sliding blocks 92 are slid to make the four mounting plates 93 press against the inner wall of the brake disc, facilitating the limited installation of the brake disc. The rubber pads 94 increase friction to improve the limiting effect. A sleeve 95 is provided on the operating platform 1, and four connecting rods 96 are rotatably connected to the sliding blocks 92. The connecting rods 96 and the sleeve 95 rotate... The movable sleeve 95 can move up and down, which can drive the connecting rod 96 to move, and then drive the four sliding blocks 92 to move synchronously, making the operation more convenient. A threaded rod 97 is rotatably connected to the operating table 1 through a bearing. The threaded rod 97 is threadedly connected to the sleeve 95. A third motor 98 is fixedly connected to the operating table 1. The threaded rod 97 is driven to rotate by the third motor 98. The output end of the third motor 98 is connected to the threaded rod 97 through a reducer and a coupling. The motor model is 17HS4401. First, the power is turned on to power the control system of the third motor 98. Then, the third motor 98 is started to drive the threaded rod 97 to rotate, which in turn drives the sleeve 95 to move up and down.
[0031] Working principle: The brake disc is installed on the operating table 1. The output end of the second motor 7 is connected to the mounting block 10 through a reducer and coupling. The motor model is SM3500. First, the power is turned on to power the control system of the second motor 7. Then, starting the second motor 7 can drive the mounting block 10 to rotate, which in turn drives the drill bit 11 to rotate. The first motor 6 model is 17HS4401. Starting the first motor 6 can drive the screw 5 to rotate, which can adjust the position of the drill bit 11. During drilling, the drill bit 11 vibrates, which acts on the three clamping blocks 83, causing the soft pad 85 to contact the first... Each spring 82 deforms to absorb some energy, reducing damage to the drill bit 11. This prevents the local stress from increasing instantaneously due to vibration at the moment of contact between the drill bit 11 and the workpiece, exceeding the material's tolerance limit. If this causes microcracks to form at these stress concentration points, and these microcracks gradually expand as cutting continues, eventually leading to the drill bit 11 chipping, the first spring 82 immediately returns to its original position, releasing the absorbed energy. The damping rod 84 converts this energy into heat through internal friction, reducing the duration and amplitude of continuous vibration. When the drill bit 11 is not in use, a protective cover 86 is provided. The sliding cover 87 covers the outside of the drill bit 11, protecting it. When the drill bit 11 descends for operation, the rubber block 88 abuts against the surface of the brake disc, and the sliding cover 87 slides upward, preventing debris from flying. The slider 810 slides in the groove 89, making the movement of the sliding cover 87 more stable. After the rubber block 88 abuts against the brake disc, as the drill bit 11 continues to descend, the second spring 811 gradually contracts. Therefore, the rebound force of the second spring 811 acts on the slider 810, making the limit more stable. The brake disc is placed on the operating table 1, and then the sliding block is slid. 92 allows the four mounting plates 93 to abut against the inner wall of the brake disc, facilitating the limiting installation of the brake disc. The rubber pad 94 increases friction to improve the limiting effect. The up-and-down moving sleeve 95 can drive the connecting rod 96 to move, thereby driving the four sliding blocks 92 to move synchronously, making operation more convenient. The output end of the third motor 98 is connected to the threaded rod 97 through a reducer and coupling. The motor model is 17HS4401. First, the power is turned on to power the control system of the third motor 98. Then, starting the third motor 98 can drive the threaded rod 97 to rotate, thereby driving the sleeve 95 to move up and down.
