Description

Technical Field

[0001] This utility model relates to the field of flange processing, and in particular to a high-efficiency drilling and positioning device for flanges. Background Technology

[0002] A flange is a common mechanical fastening element, disc-shaped, typically with a ring of evenly distributed bolt holes. Its main function is to reliably connect pipes, valves, pumps, or other equipment, forming a removable sealing system.

[0003] When manufacturing flanges, if drilling is required for flanges of other sizes, workers need to fix the locking device. However, the existing device requires disassembling and assembling screws and a series of parts to replace the locking device, which causes great trouble for the operators and reduces the efficiency of flange drilling. Furthermore, when drilling one hole and then processing the next hole on the flange, the drill bit usually needs to travel a long distance, resulting in reduced drilling efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency drilling and positioning device for flanges, which aims to improve the problems of inconvenience in clamping flanges of any size and inconvenient rotation of the positioning device in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency drilling and positioning device for flanges, comprising a base, characterized in that: a turntable is rotatably connected to the inner wall of the base, a fixing mechanism is provided on the inner wall of the base, and a rotating mechanism is provided on the inner wall of the base;

[0006] The fixing mechanism includes a fixing ring fixedly connected to the inner wall of the turntable. A fixing rod is slidably connected to the inner wall of the fixing ring. A gear ring is slidably connected to the inner wall of the fixing rod, and the gear ring meshes with a gear. A rotating sleeve is fixedly connected to the center of the inner wall of the gear. A first threaded rod is threadedly connected to the inner wall of the rotating sleeve. An inclined block is slidably connected to the inner wall of the bottom end of the rotating sleeve. A connecting rod is slidably connected to the inner wall of the inclined block. The inclined block is elastically connected to the outer wall of the connecting rod by a spring. A fixing sleeve is fixedly connected to the inner wall of the turntable.

[0007] As a further description of the above technical solution: the rotating mechanism includes a second threaded rod, which is threadedly connected to the inner wall of the base. A throttle handle is fixedly connected to the right side wall of the second threaded rod, and a fixing block is rotatably connected to the second threaded rod.

[0008] As a further description of the above technical solution: the gear is rotatably connected to the inner wall of the fixed ring.

[0009] As a further description of the above technical solution: the inner wall of the fixing rod is provided with a sloping groove, and the inner wall of the gear ring is provided with an extrusion block.

[0010] As a further description of the above technical solution: the connecting rod is fixedly connected to the inner wall of the bottom end of the rotating sleeve.

[0011] As a further description of the above technical solution: one end of the spring is fixedly connected to the inner wall of the inclined block, and the other end of the spring is fixedly connected to the inner wall of the connecting rod.

[0012] As a further description of the above technical solution: the fixing block is slidably connected to the inner wall of the base.

[0013] As a further description of the above technical solution: the fixing block is in contact with the turntable.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the rotating sleeve drives the gear to rotate, and the gear rotates to drive the gear ring to move. When the gear ring moves, it squeezes the inclined groove on the inner wall of the fixing rod through the squeezing block to squeeze the fixing rod to complete the fixing with the flange, thereby improving the problem of the prior art that it is not convenient to clamp flanges of any size.

[0016] 2. In this utility model, the movable fixing rod drives the turntable to rotate, so that the clamping flange rotates to the next required point for drilling, thereby improving the problem of inconvenient rotation of the positioning device in the prior art, reducing the required travel of the drill bit, and improving drilling efficiency.

[0027] Reference Figures 2-3 As shown, the fixing mechanism 2 includes a fixing ring 24, which can roughly limit the flange. The fixing ring 24 is fixedly connected to the inner wall of the turntable 4. A fixing rod 21 is slidably connected to the inner wall of the fixing ring 24. The inner wall of the fixing rod 21 has a sloping groove. The fixing rod 21 can fix and lock the flange. A gear ring 22 is slidably connected to the inner wall of the fixing rod 21. A pressing block is provided on the inner wall of the gear ring 22. The gear ring 22 moves to move the pressing block to press the sloping groove on the inner wall of the fixing rod 21 and move it. The gear ring 22 meshes with a gear 23. The gear 23 can drive the gear ring 22 to rotate. A rotating sleeve 25 is fixedly connected to the center of the inner wall of the gear 23. The rotation of the rotating sleeve 25 can drive the gear 23 to rotate.

[0028] Reference Figures 4-5As shown, a first threaded rod 26 is threadedly connected to the inner wall of the rotating sleeve 25. The first threaded rod 26 can press the inclined block 28 and the auxiliary fixing rod 21 to clamp the flange. An inclined block 28 is slidably connected to the inner wall of the bottom end of the rotating sleeve 25. The inclined block 28 can press the inclined surface outward to press the auxiliary fixing rod 21 to clamp the flange through the first threaded rod 26. A connecting rod 29 is slidably connected to the inner wall of the inclined block 28. The connecting rod 29 is fixedly connected to the inner wall of the bottom end of the rotating sleeve 25. The connecting rod 29 can help the inclined block 28 slide and... Furthermore, to ensure the stable connection of spring 210, the inclined block 28 is elastically connected to the outer wall of connecting rod 29 through spring 210. One end of spring 210 is fixedly connected to the inner wall of inclined block 28, and the other end of spring 210 is fixedly connected to the inner wall of connecting rod 29. Spring 210 can allow the first threaded rod 26 to automatically return to the inner wall of rotating sleeve 25 after releasing the pressure on inclined block 28. The inner wall of turntable 4 is fixedly connected to fixed sleeve 27, which can help stabilize the inclined block 28 when it is squeezed and locked.

[0029] Reference Figure 6 As shown, the rotating mechanism 3 includes a second threaded rod 32. The second threaded rod 32 can fix the fixing block 33 against the turntable 4 through the thread. The second threaded rod 32 is threaded to the inner wall of the base 1. A handle 31 is fixedly connected to the right side wall of the second threaded rod 32. The handle 31 can facilitate the rotation of the second threaded rod 32. The second threaded rod 32 is rotatably connected to the fixing block 33. The fixing block 33 is slidably connected to the inner wall of the base 1. The fixing block 33 is in contact with the turntable 4. The fixing block 33 can abut against the turntable 4 to prevent it from rotating and achieve positioning and fixation.

[0030] In use, the rotating sleeve 25 is twisted to drive the gear 23 to rotate. When the gear 23 rotates, it drives the gear ring 22 to move. When the gear ring 22 moves, it squeezes the inclined groove on the inner wall of the fixing rod 21 through the extrusion block to fix the fixing rod 21 to the flange. Then, the first threaded rod 26 is rotated to squeeze the inclined block 28 out and make the rotating sleeve 25 contact the fixing sleeve 27, thereby completing the flange fixing.

[0031] When it is necessary to adjust the drilling position of the flange, first turn the handle 31 to make the second threaded rod 32 drive the fixing block 33 to disengage from the turntable 4. Then, move the fixing rod 21 to drive the turntable 4 to rotate, so that the flange is rotated to the next required point for drilling. Then turn the handle 31 in the opposite direction to make the second threaded rod 32 drive the fixing block 33 to contact the turntable 4, thereby completing the adjustment of the drilling position of the flange.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
