Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: a pipe nozzle milling and processing tooling, including a base 1 and a pipe fitting 7. A vertical frame 2 is fixedly connected to the upper surface of the base 1. A first limiting chute 201 is opened inside the vertical frame 2. A first limiting slider 3 is slidably installed inside the first limiting chute 201. A power motor 302 is fixedly connected to one side of the first limiting slider 3. The output end of the power motor 302 is fixedly connected to a chuck 303. A milling cutter 304 is clamped inside the chuck 303. A V-shaped fixing seat 4 is slidably installed on the upper surface of the base 1. The pipe fitting 7 is placed on the V-shaped fixing seat 4. A support frame 6 is fixedly connected to the position near the rear edge on the upper surface of the V-shaped fixing seat 4. A second limiting chute 601 is opened inside the support frame 6. A second limiting slider 603 is slidably installed inside the second limiting chute 601. A pressing plate 605 is fixedly connected to one side of the second limiting slider 603.

[0023] In this embodiment, by placing the pipe fitting 7 inside the V-shaped groove on the V-shaped fixing base 4, the pipe fitting 7 can be quickly positioned. Subsequently, moving the second limit slider 603 drives the pressing plate 605 to move downward, causing the pressing plate 605 to press the upper surface of the pipe fitting 7, thereby fixing the pipe fitting 7 in the V-shaped groove of the V-shaped fixing base 4. For pipe fittings 7 with different diameters, the center after fixing will change. Moving the first limit slider 3 can drive the milling cutter 304 to move up and down, so that the center of the milling cutter 304 is aligned with the center of the pipe fitting 7, and thus different-diameter pipe fittings 7 can be quickly clamped. Starting the power motor 302 drives the chuck 303 to rotate, and the rotation of the chuck 303 drives the milling cutter 304 to rotate. Moving the V-shaped fixing base 4 closer to the milling cutter 304, the V-shaped fixing base 4 drives the pipe fitting 7 to move, thereby milling the end face of the pipe fitting 7.

[0024] Among them, in order to achieve the purpose of moving the V-shaped fixing base 4, the following technical solution is adopted for this device: a dovetail chute 101 is opened on the base 1, a dovetail slider 401 is fixedly connected to the lower surface of the V-shaped fixing base 4, the dovetail slider 401 is slidably matched with the dovetail chute 101, a first screw rod 102 is rotatably installed in the dovetail chute 101, a first threaded through hole 402 is opened in the dovetail slider 401, the first threaded through hole 402 is threadedly matched with the first screw rod 102, a first driving motor 103 is fixedly connected to one side of the base 1, and the output end of the first driving motor 103 is fixedly connected to the first screw rod 102. A second screw rod 202 is rotatably installed in the first limit chute 201, a threaded sleeve block 301 is embedded in the first limit slider 3, the threaded sleeve block 301 is threadedly matched with the second screw rod 202, and a second driving motor 203 is fixedly connected to the vertical frame 2, and the output end of the second driving motor 203 is fixedly connected to the second screw rod 202.

[0025] By starting the first driving motor 103, the first screw rod 102 can be driven to rotate. The first screw rod 102 is threadedly matched with the first threaded through hole 402. Therefore, the rotation of the first screw rod 102 can drive the dovetail slider 401 to move, and the movement of the dovetail slider 401 drives the V-shaped fixing base 4 to move, thereby moving the V-shaped fixing base 4 left and right. Starting the second driving motor 203 can drive the second screw rod 202 to rotate. The second screw rod 202 is threadedly matched with the threaded sleeve block 301. Therefore, the rotation of the second screw rod 202 can drive the first limit slider 3 to move, and the movement of the first limit slider 3 drives the milling cutter 304 to move, thereby adjusting the height of the milling cutter 304.

[0026] Among them, in order to achieve the purpose of resisting the rear end of the pipe fitting 7, the present device adopts the following technical solution: A plugging groove 403 is provided on one side of the V-shaped fixed seat 4, and an L-shaped abutting block 404 is slidably installed in the plugging groove 403. A clamping chute 5 is provided on one side of the V-shaped fixed seat 4 and above the first driving motor 103. Two L-shaped clamping blocks 502 are symmetrically and slidably installed in the clamping chute 5. A bidirectional threaded rod 501 is rotatably installed in the clamping chute 5. A second threaded through hole 503 is provided in the L-shaped clamping block 502, and the second threaded through hole 503 is in threaded cooperation with the L-shaped clamping block 502. Rubber anti-slip pads 504 are fixedly connected to the opposite surfaces of the two L-shaped clamping blocks 502. A third screw rod 602 is rotatably installed in the second limit chute 601, and a third threaded through hole 604 is provided in the second limit slider 603, and the third threaded through hole 604 is in threaded cooperation with the third screw rod 602.

[0027] By adjusting the depth of insertion of the L-shaped abutting block 404 into the plugging groove 403, the distance between the vertical end of the L-shaped abutting block 404 and the V-shaped fixed seat 4 can be adjusted, so that the vertical section of the L-shaped abutting block 404 contacts the end of the pipe fitting 7. Subsequently, rotating the bidirectional threaded rod 501 can drive the two L-shaped clamping blocks 502 to approach each other. The L-shaped clamping blocks 502 will clamp on the front and back surfaces of the L-shaped abutting block 404, thereby fixing the L-shaped abutting block 404. At this time, the L-shaped abutting block 404 will provide a supporting force for the end of the pipe fitting 7 to prevent the front end of the pipe fitting 7 from sliding after being stressed. The rubber anti-slip pads 504 are used to increase the friction between the L-shaped clamping blocks 502 and the L-shaped abutting block 404. The third screw rod 602 is in threaded cooperation with the second limit slider 603. Rotating the third screw rod 602 can drive the second limit slider 603 to move, and the movement of the second limit slider 603 will drive the pressing plate 605 to move.

[0028] The working principle and usage process of the present utility model: When in use, the device needs to be placed in a suitable position, and the pipe fitting 7 to be processed is placed inside the V-shaped groove on the V-shaped fixed seat 4. Subsequently, rotate the third screw rod 602 to drive the pressing plate 605 to move downward, so that the pressing plate 605 presses on the pipe fitting 7. Adjust the position of the L-shaped abutting block 404 so that the vertical section of the L-shaped abutting block 404 contacts the end of the pipe fitting 7. Subsequently, rotate the bidirectional threaded rod 501 to drive the L-shaped clamping blocks 502 to clamp and fix the L-shaped abutting block 404. According to the center of the pipe fitting 7, start the second driving motor 203 to drive the first limit slider 3 to move. The first limit slider 3 will drive the milling cutter 304 to move, so that the milling cutter 304 is aligned with the center of the pipe fitting 7. At this time, the power motor 302 can be started to drive the milling cutter 304 to rotate, and the first driving motor 103 is started to drive the V-shaped fixed seat 4 to move. The movement of the V-shaped fixed seat 4 will drive the pipe fitting 7 to approach the milling cutter 304, and then the end face of the nozzle of the pipe fitting 7 is milled by the milling cutter 304.
