Detailed implementation manners

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0022] As Figures 1-8 shown, a numerically controlled gantry vertical composite machine tool includes a base 1, a processing seat 2 is fixedly connected to the base 1, a gantry 3 is arranged above the processing seat 2, a processing equipment 4 is installed on the gantry 3, a transparent protective ring 5 is arranged outside the gantry 3, a lead screw 6 is rotatably connected to one side of the gantry 3, a transmission mechanism 7 is rotatably connected to one side of the gantry 3 where the lead screw 6 is located, an annular seat 8 is rotatably connected to the bottom of the transparent protective ring 5, and two cleaning mechanisms 9 are fixedly connected to the annular seat 8.

[0023] As Figure 3As shown in the figure, a sliding seat 201 is slidably fitted on the processing seat 2. A workpiece seat 202 is fixedly connected to the sliding seat 201. An electric motor A203 is fixedly connected to the inner wall of the processing seat 2. The output end of the electric motor A203 is fixedly connected with a swing rod 204. The other end of the swing rod 204 is slidably fitted with the inner wall of the lower side of the sliding seat 201. Two annular grooves 205 are symmetrically formed in the outer circumference of the processing seat 2. An annular rack A206 is fixedly connected to the outer circumference of the processing seat 2. The electric motor A203 drives the swing rod 204 to rotate, so that the other end of the swing rod 204 slides in the sliding seat 201, thereby pushing the workpiece seat 202 connected to the sliding seat 201 out of the processing seat 2.

[0024] As Figure 4 shown in the figure, two sliders 301 are fixedly connected to the position of the lower end of the gantry 3 close to the processing seat 2. The sliders 301 are slidably fitted with the inner wall of the annular groove 205. Electric motors B302 are fixedly connected to the positions of both sides of the gantry 3 close to the lower end. The output ends of the electric motors B302 are fixedly connected with driving wheels 303. The driving wheels 303 are meshed and driven with the annular rack A206. Two rollers 304 are rotatably connected to the bottom surfaces of both ends of the gantry 3 in a symmetrical structure. The rollers 304 are in sliding contact with the base 1. Racks 305 are fixedly connected to both sides of the upper end of the gantry 3. The electric motors B302 drive the connected driving wheels 303 to rotate, so that the driving wheels 303 are meshed with the annular rack A206, thereby driving the gantry 3 to be adjusted to a suitable position. The rollers 304 make it more labor-saving when the gantry 3 rotates.

[0025] As Figure 5 shown in the figure, an electric motor C601 is fixedly connected to the top end of the lead screw 6. The electric motor C601 is fixedly connected to the top end of the gantry 3. A driving wheel 602 is fixedly connected to the position of the lead screw 6 close to the top end. A moving frame 603 is threadedly connected to the outer wall of the lead screw 6. The other end of the moving frame 603 is fixedly connected to the transparent protective ring 5. The electric motor C601 drives the connected lead screw 6 to rotate, so that the lead screw 6 drives the transparent protective ring 5 connected to the moving frame 603 to move downward. The lead screw 6 can drive the transparent protective ring 5 to move up and down, facilitating the loading and unloading of workpieces.

[0026] As Figure 6As shown, the transmission mechanism 7 includes a transmission rod 701. Both ends of the transmission rod 701 are rotatably connected to the inner wall of the gantry 3. A plurality of transmission teeth 702 are rotatably connected to the inner wall of the top end of the transmission rod 701 in an annular structure. A tension spring 703 is fixedly connected between the transmission teeth 702 and the transmission rod 701. An open-slot gear 704 is rotatably connected to the outer wall of the top end of the transmission rod 701. The tooth grooves on the inner wall of the open-slot gear 704 are movably meshed and transmitted with the transmission teeth 702. The open-slot gear 704 is meshed and transmitted with the driving wheel 602. The tension spring 703 enables the transmission teeth 702 not to mesh with the open-slot gear 704 when the transparent protective ring 5 moves downward.

[0027] A rotating sleeve 705 is slidably fitted on the outer wall of the transmission rod 701. The rotating sleeve 705 is rotatably connected to the moving frame 603. A driven wheel 706 is fixedly connected to the rotating sleeve 705. When the lead screw 6 drives the transparent protective ring 5 to move upward and reset, the driving wheel 602 connected to the lead screw 6 will drive the open-slot gear 704 to rotate. At this time, the tooth grooves on the inner wall of the open-slot gear 704 will mesh with the transmission teeth 702, thereby driving the transmission rod 701 connected to the transmission teeth 702 to rotate, causing the transmission rod 701 to drive the driven wheel 706 connected to the rotating sleeve 705 to rotate, and enabling the driven wheel 706 to drive the annular seat 8 connected to the annular rack B801 to rotate.

[0028] A transparent protective ring 5 is provided on the gantry 3, which can block outside the machining tool and the workpiece during machining, effectively preventing flying chips, coolant or other machining substances from harming the operator. The transparent protective ring 5 isolates the tool and the workpiece, avoiding accidental splashing or collision during the machining process and ensuring the safety of the operator. In addition, from the perspective of the convenience of machining operations, the operator can view the machining situation in real time through the transparent protective ring 5 and make adjustments quickly when problems occur, thereby improving the machining quality and efficiency.

[0029] As Figure 7 shown, an annular rack B801 is fixedly connected to the inner circle of the annular seat 8. The annular rack B801 is meshed and transmitted with the driven wheel 706.

[0030] As Figure 8 shown, the cleaning mechanism 9 includes two fixing frames 901. The bottom ends of the fixing frames 901 are fixedly connected to the annular seat 8. A sponge rod 902 is fixedly connected to the fixing frames 901. The sponge rod 902 is in sliding contact with the transparent protective ring 5.

[0031] A universal joint 903 is rotatably connected to a fixed bracket 901 near the gantry 3. One end of the universal joint 903 is fixedly connected to a reciprocating lead screw 904. A self-cleaning ring 905 is slidably fitted on the reciprocating lead screw 904. The self-cleaning ring 905 is in sliding contact with the sponge rod 902. The other end of the universal joint 903 is fixedly connected to an electric push rod 906. The other end of the electric push rod 906 is fixedly connected to a transmission wheel 907. The transmission wheel 907 is meshed and driven with a rack 305. The electric push rod 906 enables the transmission wheel 907 not to mesh with the rack 305 when the transparent protective ring 5 moves upward. When the transparent protective ring 5 moves downward, the electric push rod 906 drives the connected transmission wheel 907 to move to a position where it can mesh with the rack 305. Then, when the transparent protective ring 5 moves downward, the transmission wheel 907 meshes with the rack 305, thereby driving the reciprocating lead screw 904 connected to the universal joint 903 to rotate, and thus driving the self-cleaning ring 905 to reciprocate up and down to clean the chips attached to the outside of the sponge rod 902.

[0032] Working principle: When machining a workpiece is required, first, the motor A 203 drives the swing rod 204 to rotate, causing the other end of the swing rod 204 to slide within the slide block 201, thereby pushing the workpiece seat 202 connected to the slide block 201 out of the machining seat 2. After placing the workpiece on the workpiece seat 202 and fixing it, the workpiece seat 202 returns to the machining seat 2. Then, when machining, the gantry 3 is rotated to an appropriate angle. The motor B 302 drives the connected drive wheel 303 to rotate, causing the drive wheel 303 to mesh with the annular rack A 206, thereby driving the gantry 3 to adjust to an appropriate position. Then, the motor C 601 drives the connected lead screw 6 to rotate, causing the lead screw 6 to drive the transparent protective ring 5 connected to the moving frame 603 to move downward, blocking the outside of the machining equipment 4 and the workpiece to intercept and block flying chips, etc. When the transparent protective ring 5 moves downward, the electric push rod 906 drives the connected transmission wheel 907 to move to a position where it can mesh with the rack 305. Then, when the transparent protective ring 5 moves downward, the transmission wheel 907 meshes with the rack 305, thereby driving the reciprocating lead screw 904 connected to the universal joint 903 to rotate, and thus driving the self-cleaning ring 905 to reciprocate up and down to clean the chips attached to the outside of the sponge rod 902. After processing is completed, when the lead screw 6 drives the transparent protective ring 5 to move upward and reset, the driving wheel 602 connected to the lead screw 6 will drive the slotted gear 704 to rotate. At this time, the tooth grooves on the inner wall of the slotted gear 704 will engage with the transmission teeth 702, thereby driving the transmission rod 701 connected to the transmission teeth 702 to rotate, causing the transmission rod 701 to drive the driven wheel 706 connected to the rotating sleeve 705 to rotate, causing the driven wheel 706 to drive the annular seat 8 connected to the annular rack B801 to rotate, enabling the sponge rod 902 on the annular seat 8 to clean both the inner and outer sides of the transparent protective ring 5, cleaning the chips and cutting fluid adhering to the inner wall of the transparent protective ring 5, and ensuring the transparency of the transparent protective ring 5.
