[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Figure 1 This invention presents a schematic diagram of the first structure of the drill bit conversion mechanism. Figure 2 This invention shows a second structural schematic diagram of the drill bit conversion mechanism. Figure 3 A schematic diagram of the base structure in this utility model is shown. Figure 4 A quarter-section view of the drill bit conversion mechanism of this invention is shown. Figure 5 A schematic diagram of the buffer mechanism in this utility model is shown. Figure 6 A cross-sectional view of the buffer mechanism in this invention is shown. Figure 7A schematic diagram of the clamping mechanism in this utility model is shown. The drill bit conversion mechanism includes: a base 1 and a drive cylinder 2 inserted into the base 1; the base 1 has multiple drill bit mounting holes 11, which are evenly distributed on the end face of the base 1, and multiple insertion holes 12 are provided on the inner wall of the base 1, each insertion hole 12 communicating with the corresponding drill bit mounting hole 11; the drive cylinder 2 has multiple claws 21, and a clamping mechanism 22 is fixedly installed on each claw 21. The output end of the clamping mechanism 22 is inserted into the corresponding insertion hole 12. The clamping mechanism 22 is driven by the drive cylinder 2 to move in the corresponding insertion hole 12 to clamp or release the drill bit 4; a rotating cylinder 3 is provided at the end of the drive cylinder 2 away from the base 1. The drive cylinder 2 is driven by the rotating cylinder 3 to rotate, thereby driving the base 1 to rotate. In this embodiment, the drive cylinder 2 has four claws 21, each claw 21 is provided with a clamping mechanism 22, and the base 1 has eight drill bit mounting holes 11, which are evenly distributed on the end face of the base 1, that is, the included angle between two adjacent drill bit mounting holes 11 is the same. The inner wall of the base 1 is provided with eight insertion holes 12, one of the eight insertion holes 12 is connected to one of the eight drill bit mounting holes 11, and the insertion hole 12 is located in the middle area of ​​the drill bit mounting hole 11. The clamping mechanism 22 is used to adjust the tightness of the drill bit 4 in the drill bit mounting hole 11. When the clamping mechanism 22 is driven by the drive cylinder 2 to move along the insertion hole 12 towards the drill bit mounting hole 11, it can clamp the drill bit 4. Conversely, when the clamping mechanism 22 is driven by the drive cylinder 2 to move along the insertion hole 12 away from the drill bit mounting hole 11, it can release the drill bit 4. The output end of the rotating cylinder 3 is connected to the drive cylinder 2. When the output end of the rotating cylinder 3 starts to rotate, it drives the drive cylinder 2 to rotate, which in turn drives the base 1 to rotate. The rotation of the base 1 can adjust the position of the eight drill bit mounting holes 11. The eight drill bit mounting holes 11 are respectively equipped with drill bits 4 of different specifications. By rotating the base 1, the eight drill bit mounting holes 11 can be aligned with the corresponding electric drills, eliminating the need for manual replacement of drill bits 4 and improving work efficiency.

[0032] It should be noted that this drill bit conversion mechanism is installed on automated equipment. This mechanism can accommodate eight drill bits of different models, allowing the automated equipment to operate according to various usage scenarios and improving work efficiency. Furthermore, this drill bit conversion mechanism is lightweight and compact compared to the entire automated equipment, offering greater flexibility in spatial layout and increasing the robot's range of motion.

[0033] Furthermore, a rubber sleeve 111 is provided inside any of the drill bit mounting holes 11, and the rubber sleeve 111 has an opening corresponding to the position of the insertion hole 12. The rubber sleeve 111 is used to reduce the risk of the drill bit 4 directly colliding with the drill bit mounting hole 11, avoiding collision between the drill bit 4 and the inner wall of the drill bit mounting hole 11 when the drill bit 4 is inserted into the corresponding drill bit mounting hole 11, which would cause damage to the drill bit 4 and help extend the service life of the drill bit 4. Secondly, the rubber sleeve 111 can also increase the friction between the drill bit 4 and the drill bit mounting hole 11. When the drill bit 4 is inserted into the corresponding drill bit mounting hole 11, the drill bit 4 exerts a force on the rubber sleeve 111, causing the rubber sleeve 111 to deform, increasing the area between the rubber sleeve 111 and the drill bit 4, thereby increasing the friction between the rubber sleeve 111 and the drill bit 4, and increasing the difficulty of pulling the drill bit 4 out of the drill bit mounting hole 11. The rubber sleeve 111 has an opening to facilitate the contact between the output end of the clamping mechanism 22 and the corresponding drill bit 4. When the output end of the clamping mechanism 22 abuts against the corresponding drill bit 4, the output end of the clamping mechanism 22 exerts a force on the drill bit 4, increasing the contact area between the drill bit 4 and the rubber sleeve 111, thereby increasing the friction between the drill bit 4 and the rubber sleeve 111, increasing the difficulty of pulling the drill bit 4 out of the drill bit mounting hole 11, reducing the risk of the drill bit 4 falling out of the corresponding drill bit mounting hole 11, and ensuring that the drill bit 4 is fixed in the corresponding drill bit mounting hole 11 during use.

[0034] Furthermore, a buffer mechanism 112 is provided at the end of any of the drill bit mounting holes 11. The buffer mechanism 112 includes a buffer spring 1121 and a buffer stop 1122. One end of the buffer spring 1121 is connected to the buffer stop 1122, and the other end of the buffer spring 1121 is connected to the bottom of the drill bit mounting hole 11. In this embodiment, the buffer mechanism 112 is used to increase the friction between the drill bit and the drill changer disc, ensuring sufficient friction to fix the drill bit until the drill chuck aligns with the drill bit chuck when changing the drill bit. This reduces the risk of the drill bit rotating and failing to align with the chuck when changing the drill bit. Simultaneously, the buffer mechanism also increases the friction between the drill bit and the drill changer hole in a stationary state, thereby increasing the stability of the drill bit while stationary in the drill changer hole and reducing the risk of the drill bit falling out of the corresponding drill changer hole on its own. The buffer spring is used to absorb the impact force of the drill bit when it is inserted into the corresponding drill hole. When the buffer spring 22 is in the compressed state, it absorbs the impact force output by the drill bit to the buffer mechanism 2. When the buffer spring 22 is in the natural state, that is, when the drill bit is pulled out of the corresponding drill hole, it releases the impact force output by the drill bit to the buffer mechanism 2. During the deformation process, the buffer spring 1121 will convert the force of the drill bit 4 on the buffer stop 1122 into elastic potential energy for storage, thereby playing a buffering role, reducing the damage of the reaction force to the drill bit 4, and thus extending the service life of the drill bit 4.

[0035] Furthermore, a limiting block 113 is provided at one end of the buffer mechanism 112 away from the bottom of the drill bit mounting hole 11, and a cross groove 1131 is provided on the limiting block 113. In this embodiment, the limiting block 113 is used to restrict the rotation of the corresponding drill bit 4, and the cross groove 1131 matches the head of the drill bit 4. When the drill bit 4 spirally extends into the drill bit mounting hole 11 until the head of the drill bit 4 is stuck in the cross groove 1131, the inner wall of the cross groove 1131 has a reaction force on the drill bit 4, locking the drill bit 4, so that the drill bit 4 cannot continue to rotate, avoiding the drill bit 4 from continuously rotating in the drill bit mounting hole 11, ensuring that the contact surface between the drill bit 4 and the drill bit mounting hole 11 remains stationary, and reducing wear caused by continuous friction.

[0036] Furthermore, the clamping mechanism 22 includes: a T-shaped block 221 and two connecting rods 222 symmetrically distributed on the T-shaped block 221, with each connecting rod 222 correspondingly inserted into the insertion hole 12; the connecting rod 222 is driven by the driving cylinder 2 to move in the corresponding insertion hole 12 to clamp or release the drill bit 4. In this embodiment, each clamping mechanism 22 has one T-shaped block 221 and two symmetrically distributed connecting rods 222, and the entire drill bit conversion mechanism has a total of four T-shaped blocks 221 and eight connecting rods 222, with one of the eight connecting rods 222 correspondingly inserted into one of the eight insertion holes 12. All four clamping mechanisms 22 are simultaneously driven by the driving cylinder 2, that is, the eight connecting rods 222 are driven by the driving cylinder 2 to move in the corresponding insertion holes 12. When all eight connecting rods 222 are simultaneously driven by the drive cylinder 2 to move along the corresponding insertion holes 12 towards the drill bit 4, the ends of all eight connecting rods 222 abut against the sidewall of the corresponding drill bit 4. Radial pressure is applied to the drill bit 4 through the elastic deformation or pre-tightening force of the ends of the connecting rods 222. The rebound of the ends of the connecting rods 222 then wraps around the drill bit 4, forming a locking force, thereby locking the drill bit 4. Conversely, when all eight connecting rods 222 are simultaneously driven by the drive cylinder 2 to move along the corresponding insertion holes 12 away from the drill bit 4, the ends of the eight connecting rods 222 do not contact the corresponding drill bit 4. The corresponding drill bit 4 is not affected by external force and can be smoothly pulled out of the mounting hole of the drill bit 4.

[0037] Furthermore, each of the connecting rods 222 has a connecting groove 2221 at one end near the T-shaped block 221, and the connecting end of the T-shaped block 221 is located within the connecting groove 2221. In this embodiment, the connecting groove 2221 is used to connect the corresponding T-shaped block 221. The connecting end of the T-shaped block 221 is engaged in the corresponding connecting groove 2221, and the two side walls of the connecting groove 2221 clamp the connecting end of the T-shaped block 221, increasing the connection strength between the connecting rod 222 and the T-shaped block 221. This prevents the connecting rod 222 from detaching from the connecting groove 2221 during use, thereby reducing the risk of the connecting rod 222 detaching from the T-shaped block 221 and ensuring the stable operation of the conversion drill bit mechanism.

[0038] Furthermore, a fixing part 223 is provided within the connecting groove 2221. The fixing part 223 includes a fixing frustum and connecting posts located on the two end faces of the fixing frustum. The fixing frustum is connected to the connecting groove 2221 based on the connecting posts. The fixing part 223 is used to strengthen the connection strength between the connecting rod 222 and the T-shaped block 221. The side wall of the fixing frustum abuts against the T-shaped block 221, and the fixing frustum is connected to the inner wall of the connecting groove 2221 based on the two connecting posts. This ensures that the connecting end of the T-shaped block 221 is surrounded within the connecting groove 2221, which helps to strengthen the connection strength between the connecting rod 222 and the T-shaped block 221, reduces the risk of the connecting rod 222 detaching from the T-shaped block 221, and ensures the stable operation of the conversion drill bit mechanism.

[0039] Furthermore, a silicone pad 224 is provided at the end of any of the connecting rods 222, and the silicone pad 224 is recessed to form an arc surface on the side near the drill bit mounting hole 11. When it is necessary to clamp the drill bit 4 in the drill bit mounting hole 11, the connecting rod 222 is driven by the driving cylinder 2 to move along the insertion hole 12, so that the end of the connecting rod 222 abuts against the corresponding drill bit 4, that is, the silicone pad 224 abuts against the corresponding drill bit 4. When the connecting rod 222 abuts against the drill bit 4, the silicone pad 224 will deform, increasing the contact area between the connecting rod 222 and the corresponding drill bit 4, thereby increasing the friction between the connecting rod 222 and the corresponding drill bit 4, which helps to reduce the risk of the drill bit 4 falling out of the drill bit mounting hole 11. The silicone pad 224 is recessed on the side near the drill bit mounting hole 11 to form an arc surface, which helps the silicone pad 224 to fit the surface of the corresponding drill bit 4, increasing the contact area between the silicone pad 224 and the corresponding drill bit 4, thereby increasing the friction between the connecting rod 222 and the corresponding drill bit 4, which helps to reduce the risk of the drill bit 4 falling out of the drill bit mounting hole 11.

[0040] Furthermore, the outer wall of the base 1 is provided with multiple identification recess groups, each identification recess group corresponding to one drill bit mounting hole 11; each identification recess group includes more than one recess, and each identification recess group has a different number and arrangement of recesses. In this embodiment, the outer wall of the base 1 is provided with seven identification recess groups, each of the seven identification recess groups including more than one recess, and one group of the seven identification recess groups has a maximum of three recesses and a minimum of one recess. Each identification recess group has three positions, namely position 1, position 2, and position 3, and the seven identification recess groups have seven different arrangements: one recess occupies position 1, one recess occupies position 2, one recess occupies position 3, two recesses occupy positions 1 and 2 respectively, two recesses occupy positions 1 and 3 respectively, two recesses occupy positions 2 and 3 respectively, and three recesses occupy three positions, that is, there are a total of seven different arrangements. Seven different arrangement methods correspond to seven of the eight drill bit mounting holes 11. The last drill bit mounting hole 11 does not have a corresponding identification pit group. That is, there are eight different arrangement methods corresponding to different drill bit mounting holes 11. This makes it easy for the sensor to identify the corresponding drill bit mounting hole 11 according to the eight different arrangement methods and rotate the corresponding angle to move the corresponding drill bit 4 to the corresponding position, which is conducive to improving the intelligence of the drill bit switching mechanism.

[0041] Furthermore, the drill bit conversion mechanism is also equipped with a control module and a detection module. The detection end of the detection module faces the outer wall of the base 1. The detection module is signal-connected to the control module, the control module is signal-connected to the drive cylinder 2, and the control module is signal-connected to the rotating cylinder 3. The detection module is used to detect the identification pit group on the outer wall of the base 1. Based on the arrangement and number of pits on the identification pit group, it generates and sends a corresponding electrical signal to the control module. The control module confirms whether the base 1 has rotated to the corresponding angle based on the first electrical signal from the detection module. If the base 1 has not rotated to the corresponding angle, the control module generates and sends a second electrical signal to the rotating motor. The rotating motor continues to rotate upon receiving this second electrical signal. If the base 1 has rotated to the corresponding angle, the control module generates and sends a third electrical signal to the rotating motor and the drive cylinder 2. When the rotating motor receives the third electrical signal, it stops rotating. When the drive cylinder 2 receives the third electrical signal, it starts working and drives the clamping mechanism 22 to release the drill bit 4, so that the electric drill can replace the corresponding drill bit 4. After the electric drill has replaced the drill bit 4, the drive cylinder 2 drives the clamping mechanism 22 to clamp the drill bit 4, so that the drill bit 4 is clamped on the base 1.

[0042] In summary, this utility model connects the output end of a rotary cylinder to a drive cylinder. When the output end of the rotary cylinder starts to rotate, it drives the drive cylinder to rotate, which in turn drives the base to rotate. The rotation of the base can adjust the position of the eight drill bit mounting holes. Each of the eight drill bit mounting holes is equipped with a drill bit of a different specification. By rotating the base, the eight drill bit mounting holes can be aligned with the corresponding electric drill, eliminating the need for manual drill bit replacement and improving work efficiency.

[0043] Furthermore, the above description provides a detailed introduction to the conversion drill bit mechanism for an automated equipment application provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
