Description

Technical Field

[0001] This utility model relates to the technical field of metal tube processing equipment, specifically a metal tube compensator processing equipment. Background Technology

[0002] Metal circular compensators are mechanical devices, including metal compensators, corrugated expansion joints, metal bellows compensators, metal expansion joints, etc. They are mainly used in high, medium, and low temperature hot air pipelines and pipelines subject to high frequency mechanical vibration. They have good flexibility, corrosion resistance, high temperature resistance, and shock absorption. They can absorb the axial and lateral displacement of pipelines and are available in various specifications according to nominal diameter and form.

[0003] A search revealed a corrugated pipe compensator processing device disclosed in Chinese Patent Publication No. CN 221415076 U. The device includes a housing with a rotating column rotatably connected to it. A turntable is connected to the upper end of the rotating column. A drive mechanism for rotating the rotating column is located inside the housing. A central rod is fixed to the center of the turntable, used for positioning the compensator. Multiple clamping mechanisms are connected to the periphery of the turntable to press the compensator firmly against it. A horizontal displacement mechanism is provided on the housing, and a slide is connected to it. A vertical support plate is connected to the slide, and a lifting mechanism is provided on the support plate, connected to a lifting seat. Two upper and lower extension plates are connected to the side of the lifting seat facing the central rod. A drilling machine is mounted on the bottom surface of the two extension plates. Driving the horizontal displacement mechanism drives the drill rod of the drilling machine to the top of the turntable. By simultaneously drilling holes at both ends of the compensator using two drilling machines, efficiency is improved.

[0004] The metal pipe compensator in the aforementioned patent still has certain shortcomings in processing. When drilling holes on the surface of the existing metal pipe compensator, the compensator fixing fixture set under the drilling machine can only play a simple fixing role. Since multiple holes need to be drilled on the compensator, users need to repeatedly disassemble and assemble the compensator, which is troublesome and greatly reduces the drilling efficiency of the compensator. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a metal pipe compensator processing device, which solves the problem that when drilling holes on the surface of existing metal pipe compensators, the compensator fixing clamps set under the drilling machine can only play a simple fixing role. Since multiple holes need to be drilled on the compensator, users need to repeatedly disassemble and assemble the compensator, which is troublesome and greatly reduces the drilling efficiency of the compensator.

[0026] Please see Figure 1-4,

[0027] Example 1: A metal pipe compensator processing device includes a fixed mounting plate 1, a top support 2 is provided at the top of the fixed mounting plate 1, a drilling processing fixing component 3 is provided at the top of the top support 2, a corrugated pipe 4 is provided inside the drilling processing fixing component 3, two connecting flanges 5 are symmetrically arranged at the upper and lower ends of the corrugated pipe 4, and a processing auxiliary component 6 is provided on the top support 2.

[0028] The drilling and fixing assembly 3 includes a bottom fixing plate 301 set at the top of the top support 2. The top of the bottom fixing plate 301 has a top mounting groove 302. The side of the top mounting groove 302 is threaded through and inserted with an abutting screw 303. The top of the top mounting groove 302 is provided with a fixing base 304. The bottom of the fixing base 304 is provided with a rotating connecting block 305. The rotating connecting block 305 is rotatably connected to the bottom wall of the top mounting groove 302. The top of the fixing base 304 has a fixing groove 306. The bottom connecting flange 5 is inserted into the fixing groove 306. Two clamping plates 307 are symmetrically arranged on both sides of the inner wall of the fixing groove 306. The side of the clamping plate 307 is rotatably connected with a pushing screw 308. The end of the pushing screw 308 is threaded through the inner wall of the fixing groove 306.

[0029] The processing auxiliary component 6 includes an auxiliary limiting plate 601 disposed on the side of the bellows 4. A flange limiting slot 602 is provided on the side of the auxiliary limiting plate 601. A driving groove 603 is provided in the middle of the top of the top support 2. A driving block 604 is inserted into the driving groove 603. The top of the driving block 604 is fixedly connected to the bottom side of the end of the auxiliary limiting plate 601. A driving screw 605 is rotatably inserted into the driving groove 603. The driving screw 605 is threaded through the bottom of the driving block 604. The end of the driving screw 605 rotatably extends through the driving groove 603 to the outside of the top support 2.

[0030] Example 2: The difference between this example and Example 1 is that the side wall of the clamping plate 307 is an arc shape that fits against the outer side of the connecting flange 5.

[0031] This causes the clamping plate 307 to be fixed against the side of the connecting flange 5 by the push of the push screw 308.

[0032] Example 3: The difference between this example and Example 1 is that the longitudinal section of both the drive plug 604 and the drive groove 603 is rectangular.

[0033] This allows the drive screw 605 to stably drive the drive plug 604 to slide left and right in the drive groove 603.

[0034] Example 4: The difference between this example and Example 1 is that the flange limiting slot 602 and the top side connecting flange 5 are located on the same horizontal plane.

[0035] Driven by the drive screw 605, the flange limiting slot 602 inserts the top connecting flange 5 into the flange limiting slot 602, thereby limiting and fixing the top connecting flange 5.

[0036] In this embodiment, when drilling holes on the surface of the existing metal pipe compensator, the compensator fixing fixture set under the drilling machine can only play a simple fixing role. Since multiple holes need to be drilled on the compensator, the user needs to repeatedly disassemble and assemble the compensator, which is troublesome and greatly reduces the drilling efficiency of the compensator.

[0037] In summary, when a user needs to drill holes in the connecting flanges 5 at the top and bottom of the corrugated pipe 4, the user first needs to fix the mounting plate 1 on the drilling machine platform so that the connecting flange 5 at the top of the corrugated pipe 4 is located on the bottom side of the drill bit of the drilling machine.

[0038] Next, the user inserts the connecting flange 5 on the bottom side of the bellows 4 into the fixing groove 306. The user can rotate the push screw 308 to make the clamping plate 307 abut against both sides of the connecting flange 5 and fix it. Since the bottom end of the fixing base 304 is rotatably connected to the top mounting groove 302 through the rotating connecting block 305, the bellows 4 and the connecting flange 5 can rotate. When the side of the connecting flange 5 rotates to the bottom side of the drill bit, the user rotates the abutting screw 303 to make the end of the abutting screw 303 abut against the side of the rotating connecting block 305 and fix it, thereby ensuring that the connecting flange 5 is in a fixed state.

[0039] Finally, by rotating the drive screw 605, the drive block 604 is driven by the drive screw 605 to push the flange limiting slot 602 to the side of the connecting flange 5, so that the connecting flange 5 is inserted into the flange limiting slot 602. The flange limiting slot 602 again limits and fixes the top connecting flange 5, ensuring that the side of the connecting flange 5 is more stable when drilled by the drill bit, thus making the drilling on the connecting flange 5 better. The user can effectively adjust the drilling position on the side of the connecting flange 5 by rotating the fixed base 304, thus eliminating the need for repeated disassembly and assembly of the connecting flange 5 and the bellows 4, improving the overall drilling efficiency of the connecting flange 5 and making it more convenient for the user to drill.
