Description

Technical Field

[0001] This utility model relates to the field of turret cooling technology, specifically to a chip-proof cooling structure for a built-in automatic tool changer turret. Background Technology

[0002] Turret cooling is a key technology in CNC machining that uses specific devices and media (usually coolant) to cool, lubricate, and remove chips from the cutting tools on the turret. Its core purpose is to ensure tool performance and improve machining quality and efficiency.

[0003] Existing tool cooling methods typically involve spraying coolant from nozzles at a fixed angle to cool the tool surface. However, because the spray angle is fixed, the nozzle can only spray one side of the tool surface. The other side relies solely on coolant splashing for cooling, which can easily lead to localized overheating and uneven cooling of the tool.

[0004] Therefore, a chip-proof and cooling structure for a built-in automatic tool changer turret is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a chip-proof cooling structure for a built-in automatic tool changer turret, which can solve the problem of uneven tool cooling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a housing and a main transmission mechanism fixedly connected to the inner side of the lower end of the housing. A turret is fixedly connected to one side of the main transmission mechanism. Several tool holders are fixedly connected to the outer side of the turret. A cutting tool is fixedly connected to the inner side of each tool holder. Several annular grooves are formed on the outer side of each cutting tool. A drill bit is rotatably connected to the inner side of each cutting tool. A protective box is fixedly connected to one side of the housing. A motor is installed inside the protective box. A rotating wheel is fixedly connected to the output end of the motor. An eccentric shaft is installed at one end of the rotating wheel. A rectangular groove is formed on the outer side of the eccentric shaft. A fixing block is fixedly connected to one side of the housing.

[0007] Preferably, a rotating shaft is fixedly connected to one end of the rectangular groove, and the rotating shaft is rotatably connected to one side of the fixed block.

[0008] Preferably, a cylindrical collar is fixedly connected to the upper end of the rectangular groove, and an infusion tube is fixedly connected to the inner side of the cylindrical collar.

[0009] Preferably, the end of the infusion tube away from the cylindrical collar is connected to a storage tank, and the storage tank is fixedly connected to the inner side of the lower end of the box body.

[0010] Preferably, a shunt tube is connected to the outside of the infusion tube, a nozzle is connected to the left half of the lower end of the shunt tube, and a nozzle is connected to the right half of the shunt tube.

[0011] Preferably, the motor output end and the protection box are connected through each other, and the motor and the protection box are fixedly connected.

[0012] Preferably, the eccentric shaft is fixedly connected to the side of the rotating wheel away from the center, and the eccentric shaft is slidably connected to the rectangular groove.

[0013] Compared with the prior art, this utility model provides a chip-proof and cooling structure for a built-in automatic tool changer turret, which has the following beneficial effects: 1.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Please see Figure 1 - Figure 4The chip-proof and cooling structure of the built-in automatic tool changer turret in this embodiment includes a housing 1 and a main transmission mechanism 2 fixedly connected to the inner side of the lower end of the housing 1. A tool turret 3 is fixedly connected to one side of the main transmission mechanism 2. Several tool holders 4 are fixedly connected to the outer side of the tool turret 3. A tool 14 is fixedly connected to the inner side of each tool holder 4. Several annular grooves 16 are opened on the outer side of the tool holder 4. A drill bit 15 is rotatably connected to the inner side of the tool 14. A protective box 5 is fixedly connected to one side of the housing 1. A motor 6 is arranged inside the protective box 5. A rotating wheel 7 is fixedly connected to the output end of the motor 6. An eccentric shaft 9 is arranged at one end of the rotating wheel 7. A rectangular groove 8 is arranged on the outer side of the eccentric shaft 9. A fixing block 18 is fixedly connected to one side of the housing 1. A rotating shaft is fixedly connected to one end of the rectangular groove 8, and the rotating shaft is rotatably connected to one side of the fixed block 18. A cylindrical collar 10 is fixedly connected to the upper end of the rectangular groove 8, and an infusion tube 11 is fixedly connected to the inner side of the cylindrical collar 10. The end of the infusion tube 11 away from the cylindrical collar 10 is connected to a storage tank 17, and the storage tank 17 is fixedly connected to the inner side of the lower end of the box body 1; The rotation of the turret 3 via the main drive mechanism 2, the delivery of liquid to the delivery pipe 11 via the storage tank 17, and the rotation of the wheel 7 via the motor 6 are all existing technologies, and therefore will not be described in detail in this embodiment. At this time, the power is usually provided by an electric motor. In modern high-precision machining, servo motors are often used. As a power source, the electric motor can output torque and speed to provide initial power for the rotation of the turret 3, so as to achieve the effect of changing the tool 14. By rotating the drill bit 15 inside the tool 14, the tool 14 can provide rotational support for the rotation of the drill bit 15. When the drill bit 15 rotates, the raw material can be processed. After the drill bit 15 finishes processing the raw material, the control motor 6 will drive the rotary wheel 7 to reverse. An eccentric shaft 9 is set at one end of the rotary wheel 7. When the rotary wheel 7 rotates, it will drive the eccentric shaft 9 to rotate. When the eccentric shaft 9 rotates, it will push the rectangular groove 8 set on the outside of the eccentric shaft 9. The rectangular groove 8 will swing left and right under the push of the eccentric shaft 9. The cylindrical collar 10 at the upper end of the rectangular groove 8 can connect the rectangular groove 8 to the infusion tube 11, so as to drive the infusion tube 11 to swing. The storage tank 17 delivers liquid to the infusion tube 11. The coolant will be sprayed out from the inside of the nozzle 12 and the nozzle 2 13. The sprayed coolant will fall into the surface of the tool 14 and the drill bit 15, so as to cool the surface of the tool 14 and the drill bit 15. By creating several annular grooves 16 on the outside of the tool 14, the contact area between the coolant and the tool 14 can be increased, thus improving the cooling efficiency of the tool 14. By fixing a rotating shaft to one end of the rectangular groove 8 and rotating the rotating shaft to one side of the fixed block 18, the lower half of the rectangular groove 8 is prevented from getting stuck when the upper half of the rectangular groove 8 swings, thus improving the stability of the structure. The fixed spray range of the fixed nozzle is fixed, which can easily lead to blind spots due to the rotation of the tool 14, workpiece obstruction, or changes in the processing position, resulting in excessively high local temperatures. The swinging nozzle 12 and the swinging nozzle 23 can expand the spraying area through reciprocating motion, ensuring that the cutting area, the rake face and flank face of the tool 14, and the surface to be processed of the workpiece can all be covered by cutting fluid, thus increasing the spraying area of ​​the tool 14.

[0019] A shunt tube is connected to the outside of the infusion tube 11. A nozzle 12 is connected to the left half of the lower end of the shunt tube, and a nozzle 2 13 is connected to the right half of the shunt tube. The output end of motor 6 is connected through the protection box 5, and motor 6 is fixedly connected to protection box 5; The eccentric shaft 9 is fixedly connected to the side of the rotating wheel 7 away from the center, and the eccentric shaft 9 is slidably connected to the rectangular groove 8; By setting nozzle 12 and nozzle 13 at a certain angle, the effect of spraying both sides of the blade 14 can be achieved, preventing the blade 14 from overheating due to uneven spraying on both sides. By connecting the output end of the motor 6 to the protective box 5 through the blade, the protective box 5 can be prevented from affecting the rotation of the motor 6 when the output end of the motor 6 is rotating. A sealing ring is provided at the connection between the output end of the motor 6 and the protective box 5 to prevent coolant from entering the motor 6 and causing damage. By fixing the motor 6 to the protective box 5, the problem of inaccurate transmission position of the rotating wheel 7 due to shaking of the motor 6 during rotation can be prevented. By fixing the eccentric shaft 9 to the side of the rotating wheel 7 away from the center and slidingly connecting the eccentric shaft 9 to the rectangular groove 8, when the rotating wheel 7 rotates around its own center, the eccentric shaft 9, due to being off-center from the center of rotation, will form a circular motion with the center of the rotating wheel 7 as the center and the eccentric distance as the radius. At the same time, the eccentric shaft 9 will slide inside the rectangular groove 8, achieving the effect of pushing the rectangular groove 8 to swing left and right.

[0020] The working principle of the above embodiments is as follows: When in use, the drill bit 15 can process the raw material when it rotates. After the drill bit 15 finishes processing the raw material, the control motor 6 will drive the rotary wheel 7 to reverse. An eccentric shaft 9 is set at one end of the rotary wheel 7. When the rotary wheel 7 rotates, it will drive the eccentric shaft 9 to rotate. When the eccentric shaft 9 rotates, it will push the rectangular groove 8 set on the outside of the eccentric shaft 9. The rectangular groove 8 will swing left and right under the push of the eccentric shaft 9. The cylindrical collar 10 at the upper end of the rectangular groove 8 can connect the rectangular groove 8 to the infusion tube 11, so as to drive the infusion tube 11 to swing. The storage tank 17 delivers liquid to the infusion tube 11. The coolant will be sprayed out from the inside of the nozzle 12 and the nozzle 2 13. The sprayed coolant will fall into the surface of the cutting tool 14 and the drill bit 15, so as to achieve the effect of cooling the surface of the cutting tool 14 and the drill bit 15.

[0021] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
