[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a boring head for a CNC boring and milling machine, comprising a boring head device 1 and a tool handle 5, a connecting rod 3 is fixedly connected to the bottom of the boring head device 1, a clamping groove 4 is provided at the bottom of the left and right sides of the boring head device 1, a mounting groove 6 is provided on the top wall of the tool handle 5, the bottom end of the connecting rod 3 is clamped with the mounting groove 6, the left and right sides of the tool handle 5 are rotatably connected with rotating columns 7, the two rotating columns 7 are fixedly connected with rotating plates 8 on the far sides, the two rotating plates 8 are fixedly connected with clamping blocks 9 on the adjacent sides, the front sides of the two clamping blocks 9 are provided with locking grooves 10, a spring locking rod 11 is fixedly installed on the front side of the inner wall of the boring head device 1, the rear ends of the two spring locking rods 11 are respectively clamped with the corresponding locking grooves 10, and a cleaning mechanism 2 is provided on the top wall of the boring head device 1;

[0030] Specifically, the initial fixation is completed by engaging the connecting rod 3 with the mounting groove 6. This step is simple to operate and does not require additional tools. It lays the foundation for the subsequent installation process. Pull the spring locking rods 11 at the left and right ends of the front side of the boring head device 1 in turn. After completing the above steps, we need to flip the rotating plate 8. The rotating plate 8 is flipped under the rotation of the rotating column 7. This design makes the installation process more stable and ensures the precise docking of the boring head device 1 and the tool handle 5. During the flipping process, the engaging block 9 fixed on one side of the rotating plate 8 is engaged with the engaging groove 4 on the same side. The implementation of this step further ensures the stable connection between the boring head device 1 and the tool handle 5. Next, loosen the spring locking rod 11. This step is to allow the rear end of the spring locking rod 11 to engage with the locking groove 10 provided on the front side of the engaging block 9. In this way, the boring head device 1 and the tool handle 5 can be tightly connected together, ensuring stability and safety during use. This avoids the need for additional tools for installation.

[0031] Reference Figure 1 , the front sides of the two spring locking rods 11 are fixedly connected with handles 12, and the middle part of the front side of the boring head device 1 is fixedly connected with a dial 14; the front sides of the two handles 12 are provided with protective shells 15, and the rear sides of the two protective shells 15 are rotatably connected with the middle and lower part of the front side of the boring head device 1 through hinges; the adjacent sides of the two rotating plates 8 are provided with concave surfaces;

[0032] Specifically, the two handles 12 make it easy to pull the corresponding spring locking rod 11, the protective shell 15 makes it easy to protect the front end of the spring locking rod 11, the dial 14 makes it easy to rotate the device accurately, and the adjacent sides of the two rotating plates 8 are both provided with concave surfaces, so that the two rotating plates 8 will not collide with the two sides of the handle 5, avoiding affecting the installation.

[0033] Reference Figure 1 and Figure 3 The cleaning mechanism 2 includes two fixed shells 201, and the adjacent sides of the two fixed shells 201 are fixedly connected to the left and right sides of the boring head device 1. The inner bottom walls of the two fixed shells 201 are fixedly connected with return springs 202, and the top ends of the two return springs 202 are fixedly connected with displacement columns 203. The top ends of the two displacement columns 203 are fixedly connected with cleaning shells 204, and the left and right sides of the inner wall of the cleaning shell 204 are rotatably connected with cleaning sponges 205;

[0034] Specifically, by pressing the cleaning shell 204, the two displacement columns 203 can be displaced downward, thereby compressing the two return springs 202. This design makes subsequent cleaning operations possible. In the process of compressing the two return springs 202, the cleaning shell 204 will be displaced, thereby causing the two cleaning sponges 205 to flip upward. The two cleaning sponges 205 can effectively clean both sides of the top wall of the boring head device 1. In this way, the influence of dirt is reduced during the installation process, ensuring that the equipment is clean and tidy. When releasing the installation, the elastic force of the two return springs 202 will cause the cleaning shell 204 to displace upward and return to its original position.

[0035] Reference Figure 1 The front and rear sides of the bottom wall of the cleaning shell 204 are fixedly connected with sliders 206, and the left ends of the front and rear sides of the boring head device 1 are provided with slide grooves 207, and the adjacent sides of the two sliders 206 are slidably connected with the corresponding slide grooves 207 respectively; the front side of the tool handle 5 is fixedly installed with a specification mark 13; the external size of the connecting rod 3 matches the internal size of the tool handle 5, and the external size of the two engaging blocks 9 matches the internal size of the left and right sides of the boring head device 1;

[0036] Specifically, the adjacent sides of the two sliders 206 are respectively slidably connected with the corresponding slide grooves 207, so that the cleaning shell 204 is more stable when displaced, and the specification mark 13 makes it easy to determine the model of the connecting tool handle 5. The external dimensions of the connecting rod 3 are matched with the internal dimensions of the tool handle 5, and the external dimensions of the two locking blocks 9 are matched with the internal dimensions of the left and right sides of the boring head device 1, so that the installation is smoother.

[0037] Working principle: When starting to install and connect, the connecting rod 3 is engaged with the installation groove 6 to complete the initial fixation, and the spring locking rods 11 at the left and right ends of the front side of the boring head device 1 are pulled in sequence, so that the spring locking rods 11 are pulled, and then the rotating plate 8 is flipped, so that the rotating plate 8 is flipped under the rotation of the rotating column 7, so that the locking block 9 fixed on one side of the rotating plate 8 is engaged with the locking groove 4 on the same side, and then the spring locking rod 11 is loosened, so that the rear end of the spring locking rod 11 is engaged with the locking groove 10 provided on the front side of the locking block 9, thereby completing the installation of the boring head device 1 and the tool handle 5, thereby improving the boring head The assembly efficiency of the device 1 and the tool handle 5 avoids the need for additional tools for installation, and by pressing the cleaning shell 204, the two displacement columns 203 are displaced downward, thereby compressing the two return springs 202. The displacement of the cleaning shell 204 causes the two cleaning sponges 205 to flip upward, so that both sides of the top wall of the boring head device 1 can be cleaned, thereby reducing the situation where dirt is left when installing on the machine tool and affecting the installation. When releasing the installation, the elastic force of the two return springs 202 is reset to make the cleaning shell 204 displaced upward, thereby achieving the purpose of protecting the top of the boring head device 1.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
