Technical Field

[0001] The utility model belongs to the technical field of flange production, and particularly relates to a positioning and punching device for flange production. Background Technique

[0002] A flange is also called a flange convex disc or a flange. A flange is a part used for connecting shafts to each other and is used for connecting between pipe ends; there are also flanges used at the inlets and outlets of equipment for connecting between two pieces of equipment. With the rapid development of industrial technology, the application of flanges is becoming more and more extensive. During the production process of flanges, it is necessary to use a flange processing device to punch holes for later use.

[0003] It is found that the publication (announcement) number: 202210250620.5 discloses a punching device for the surface of a flange and its use method. This technology discloses technical solutions such as "by using a circular support base and a clamping plate arranged in a sliding manner, it is convenient to fix or remove the flange, and by using a plurality of arc-shaped clamping plates with a sliding adjustment effect and the setting of rubber anti-slip protection pads on the clamping plate, a good fixing effect on the flange can be achieved", and has technical effects such as "preventing the occurrence of shaking, which may lead to inaccurate processing of the flange".

[0004] However, before processing, the punching device of the above solution fixes the flange through the clamping plate. However, during the fixing process of the flange, it is necessary to rotate the handles in four directions to respectively adjust the arc-shaped clamping plates to fix the flange. Since it is a manual operation, if there is a movement error in the arc-shaped clamping plates in four directions, it will cause the flange to be unable to be centered and fixed, thus affecting the accuracy during processing. Moreover, it is necessary to adjust the four handles for each processed flange, reducing the processing efficiency.

[0005] To solve the above problems, a positioning and punching device for flange production is proposed in this application. Content of the Utility Model

A base 4 is provided at the top of the three-axis machine tool 1. A turntable 5 is fixed on the top of the base 4. Three circumferentially distributed limit sleeves 6 are rotatably connected to the outer edge of the top of the turntable 5. Three circumferentially distributed limit frames 8 are rotatably connected to the outer edge of the top of the base 4 through a shaft rod 7. An extension ear 9 is fixed on the left side surface of the rear end of the turntable 5. A threaded sleeve 10 is rotatably connected to the top of the extension ear 9. A shaft sleeve 12 is provided on the right side rear of the turntable 5, and the shaft sleeve 12 is rotatably connected to the top of the base 4 through a rotating shaft 11. A threaded rod 13 is rotatably connected to the inside of the shaft sleeve 12. Three circumferentially distributed fixing frames 15 are fixedly connected to the outer edge of the top of the turntable 5, and a supporting ring 16 is fixed between the tops of the three fixing frames 15. In this implementation scheme, when positioning a smaller flange, the flange is placed on the turntable 5, and then the threaded rod 13 is rotated. Through the cooperation of the threaded sleeve 10 and the extension ear 9, the turntable 5 is driven to rotate, so that when the turntable 5 rotates, the limit sleeve 6 can drive the limit frame 8 to rotate around the shaft rod 7 as the axis, thereby clamping and positioning the flange in the center by the shaft rods 7 in three directions.

[0024] Specifically, a support rod 17 is fixed to the top of the end of the limit frame 8 away from the shaft rod 7. In this embodiment, when positioning a larger flange, the flange is placed on the supporting ring 16, and the inner wall of the flange is supported outward by the support rods 17 in three directions, thereby positioning it.

[0025] Specifically, a layer of flocking pad is fixed on the top surface of the turntable 5 and the top surface of the supporting ring 16. In this embodiment, when the flange is placed on the turntable 5 or the supporting ring 16, the flocking pad can avoid scratching and wear.

[0026] Specifically, the limit sleeve 6 is sleeved on the outer surface of the limit frame 8 and is slidably connected. In this embodiment, when the turntable 5 drives the limit sleeve 6 to move, the limit sleeve 6 slides along the outer surface of the limit frame 8.

[0027] Specifically, the outer surface of the threaded rod 13 and the inner surface of the threaded sleeve 10 are threadedly connected. In this embodiment, when the threaded rod 13 rotates, it can drive the threaded sleeve 10 to slide along the outer surface of the threaded rod 13.

[0028] Specifically, an internal hexagonal hole 14 is opened on the right end surface of the threaded rod 13. In this embodiment, an internal hexagonal wrench can be inserted into the inside of the internal hexagonal hole 14 to rotate the threaded rod 13.

[0029] Working principle and usage process of the present utility model: First, when it is necessary to position a smaller flange, place the flange on the turntable 5, and rotate the threaded rod 13 by inserting an Allen wrench into the interior of the Allen hole 14. The threaded rod 13 drives the turntable 5 to rotate through the cooperation of the threaded sleeve 10 and the extension ear 9, so that when the turntable 5 rotates, it can drive the limit frame 8 to rotate around the shaft rod 7 through the limit sleeve 6, thereby enabling the shaft rods 7 in three directions to clamp and position the flange in the center; when it is necessary to position a larger flange, place the flange on the support ring 16, and support the inner wall of the flange outward through the struts 17 in three directions, thereby positioning it; finally, drive the drilling machine 2 to move above the flange through the three-axis machine tool 1 for drilling processing.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
