Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, and more specifically, to a positioning device for flange production. Background Technology

[0002] A flange is a mechanical fastener, also known as a flange disc or flange. Flanges are parts used to connect shafts, typically for connecting pipe ends, and can also be used on equipment inlets and outlets to connect two pieces of equipment. There are many types of flanges, such as threaded flanges, integral flanges, and weld neck flanges. Therefore, flanges require positioning and machining.

[0003] In the common flange manufacturing process, drilling equipment is needed to drill holes in the flange, and positioning devices are needed to position the flange to facilitate the drilling process. The positioning is designed according to the type of flange. Among them, threaded flanges, as a type of flange connection, require separate design due to their unique structure and performance characteristics.

[0004] For example, Chinese patent CN212704544U discloses a positioning device for flange production and processing. Support seats are fixedly installed at the four corners of the base, and a worktable is fixedly installed on the top of the base. A turntable is movably mounted on the top of the worktable via a rotating shaft. This device discloses a positioning and processing method for ordinary flanges. Although simple and reliable, the clamping mechanism cannot be adjusted vertically, and the central support plate cannot be used to process and position specific flanges.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a positioning device for flange production to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A positioning device for flange production includes a workbench, a fixed seat at the top center of the workbench, a fixing mechanism through the top center of the fixed seat, and collection and cleaning boxes symmetrically arranged on both sides of the top of the fixed seat; lifting mechanisms are arranged on both sides of the top of the workbench, a clamping mechanism is arranged at one end of the top of the lifting mechanism, and a lateral adjustment mechanism is arranged inside the workbench.

[0009] Furthermore, to secure the threaded flange, prevent slippage, and avoid low precision, the fixing mechanism includes a drive shaft housed inside the fixing base, with a limit washer positioned in the middle of the drive shaft; a drive motor is installed at the bottom of the drive shaft, penetrating the interior of the fixing base. The limit washer has threads on its top.

[0010] Furthermore, in order to collect impurities generated during the processing of threaded flanges and keep them away from the aforementioned fixing mechanism to avoid collision, a support column connected to the fixing seat is provided at the bottom of the collection and cleaning box, and a through hole is provided in the middle of the collection and cleaning box.

[0011] Furthermore, in order to control the positioning accuracy and clamping accuracy of the clamping mechanism and the fixing mechanism, and to fix the threaded flange to prevent it from falling off and sliding, the lifting mechanism includes an outer shell set at the top of the worktable. A lifting motor is set in the middle of the outer shell. The lifting motor is connected to a threaded rod, which is connected to a through-type L-shaped quadrangular prism. Slider blocks are set on both sides of the bottom of the L-shaped quadrangular prism. The sliders cooperate with the limiting grooves opened in the outer shell.

[0012] Furthermore, for clamping and fixing the threaded flange, the clamping mechanism includes a bidirectional motor located on one side of the L-shaped quadrangular prism and close to the drive shaft. The output shafts on both sides of the bidirectional motor are connected to a first threaded rod and a second threaded rod. Both the first and second threaded rods are equipped with convex sliding plates, and a clamping plate is located on one side of the convex sliding plate. A clamping gasket is located at the bottom of the clamping plate. Limiting rods are provided on both sides of the first and second threaded rods, with end blocks at the top of the limiting rods. Limiting blocks are also provided at the top of the first and second threaded rods. The thread directions of the first and second threaded rods are opposite.

[0013] Furthermore, in order to move the lifting mechanism to a suitable position for clamping and fixing the threaded flange, the lateral adjustment mechanism includes an adjusting threaded rod located inside the worktable. The top of the adjusting threaded rod has a moving slide groove, and an adjusting motor is located on one side of the adjusting threaded rod. The adjusting threaded rod passes through the bottom outer casing.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By selecting suitable materials and performing pre-treatment steps such as drilling and hole treatment, threaded flanges are prepared and then positioned. By setting up a fixing mechanism, a lifting mechanism, a clamping mechanism, and a lateral adjustment mechanism, the threaded flange is fixed using the thread of the drive shaft of the fixing mechanism and moved to the appropriate clamping position, reducing manual intervention. Then, the lifting mechanism and clamping mechanism cooperate with the fixing mechanism to fix the threaded flange by moving it up and down. The lifting mechanism moves towards the center to reduce the slippage of the threaded flange and improve accuracy.

[0016] 2. By setting up a collection and cleaning box, impurities generated during the machining of the fixed threaded flange can be collected, improving work efficiency and not affecting positioning accuracy. Attached Figure Description

[0025] According to an embodiment of the present invention, a positioning device for flange production is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, the adjustable-thickness felt device according to an embodiment of the present utility model includes a workbench 1, a fixed seat 2 is provided at the middle of the top of the workbench 1, a fixing mechanism 3 is provided through the middle of the top of the fixed seat 2, and collection and cleaning boxes 4 are symmetrically provided on both sides of the top of the fixed seat 2; a lifting mechanism 5 is provided on both sides of the top of the workbench 1, a clamping mechanism 6 is provided at one end of the top of the lifting mechanism 5, and a horizontal adjustment mechanism 7 is provided inside the workbench 1.

[0027] By employing the above-described technical solution of this utility model, suitable materials are selected, and pre-processing steps such as drilling and orifice treatment are performed to prepare threaded flanges, followed by positioning processing. By setting up a fixing mechanism 3, a lifting mechanism 5, a clamping mechanism 6, and a lateral adjustment mechanism 7, the threaded flange is fixed using the threads of the fixing mechanism 3, reducing manual intervention. Then, the lateral adjustment mechanism 7, using the lifting mechanism 5, adjusts to a suitable position in the center, clamping different sizes. The lifting mechanism 5 and the clamping mechanism 6, in cooperation with the fixing mechanism 3, perform vertical movement to fix the threaded flange, reducing slippage and improving accuracy. A collection and cleaning box 4 is provided to collect impurities generated during the processing of the fixed threaded flange, improving work efficiency without affecting positioning accuracy.

[0028] In one embodiment, the fixing mechanism 3 includes a drive shaft 301 disposed inside the fixing base 2, with a limiting washer 302 disposed at the middle of the drive shaft 301; a drive motor 303 is disposed at the bottom of the drive shaft 301 penetrating inside the fixing base 2. The limiting washer 302 has threads on its top to fix the threaded flange, prevent slippage, and avoid low precision.

[0029] Working principle of fixing mechanism 3: After the flange is placed on top of the drive shaft 301, the drive motor 303 is started to fix the flange in a threaded manner, and the bottom limiting gasket 302 limits the threaded flange.

[0030] In one embodiment, the collection and cleaning box 4 is provided with a support column 8 at the bottom that is connected to the fixed base 2, and a through hole 9 is provided in the middle of the collection and cleaning box 4 to collect impurities generated during the processing of threaded flanges, and to keep them away from the fixed mechanism 3 so as not to collide with them.

[0031] In one embodiment, the lifting mechanism 5 includes an outer housing 501 located at the top of the workbench 1. A lifting motor 502 is located in the middle of the outer housing 501. The lifting motor 502 is connected to a threaded rod 503, which passes through and connects to an L-shaped quadrangular prism 504. Slider blocks 505 are located on both sides of the bottom of the L-shaped quadrangular prism 504. The sliders 505 cooperate with the limiting grooves 506 opened in the outer housing 501 to control the positioning accuracy and clamping accuracy of the clamping mechanism 6 and the fixing mechanism 3, and to fix the threaded flange to prevent it from falling off and sliding.

[0032] The working principle of the lifting mechanism 5: After the intermediate lifting motor 502 is started, the output shaft drives the L-shaped quadrangular prism 504 on the threaded rod 503 to move up and down. The L-shaped quadrangular prism is vacuum in the middle and has threads. The vacuum threads in the middle cooperate with the threaded rod 503 to move up and down. The sliders 505 on both sides are positioned and lifted by the limiting slide groove 506. There are also limit marks. It can also cooperate with the fixing mechanism 3 to rise and fall.

[0033] In one embodiment, the clamping mechanism 6 includes a bidirectional motor 601 disposed on one side of the L-shaped quadrangular prism 504 and close to the drive shaft 301. The output shafts on both sides of the bidirectional motor 601 are connected to a first threaded rod 602 and a second threaded rod 603. Both the first threaded rod 602 and the second threaded rod 603 are provided with a convex sliding plate 604. A clamping plate 605 is disposed on one side of the convex sliding plate 604, and a clamping gasket 606 is disposed at the bottom of the clamping plate 605. Limiting rods 607 are provided on both sides of the first threaded rod 602 and the second threaded rod 603. An end block 608 is disposed at the top of the limiting rod 607, and a limiting block 609 is disposed at the top of the first threaded rod 602 and the second threaded rod 603. The threads of the first threaded rod 602 and the second threaded rod 603 are in opposite directions, thereby clamping and fixing the threaded flange.

[0034] Working principle of clamping mechanism 6: After the bidirectional motor 601 is turned on, the first threaded rod 602 and the second threaded rod 603 move towards the middle position. The first threaded rod 602 and the second threaded rod 603 drive the clamping plate 605 of the convex sliding plate 604 to clamp towards the middle position to clamp and fix the threaded flange. The bottom of the clamping plate 605 is provided with a clamping gasket 606 to clamp the threaded flange. The top of the first threaded rod 602 and the second threaded rod 603 in the middle of one side of the convex sliding plate 604 is provided with a limit block 609 and the top of the limit rods 607 on both sides is provided with an end block 608 for limiting.

[0035] In one embodiment, the lateral adjustment mechanism 7 includes an adjusting threaded rod 701 located inside the workbench 1. The top of the adjusting threaded rod 701 has a moving slide groove 702, and the side of the adjusting threaded rod 701 has an adjusting motor 703. The adjusting threaded rod 701 passes through the bottom outer casing 501, thereby moving the lifting mechanism 5 to a suitable position for clamping and fixing the threaded flange.

[0036] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0037] In practical applications, by selecting suitable materials and performing pre-treatment steps such as drilling and orifice treatment, threaded flanges are prepared, followed by positioning processing. The selected threaded flange is placed on the thread on the drive shaft 301 of the fixing mechanism 3, and the drive motor 303 is started to move downwards (the working principle of the fixing mechanism 3 is as described above). Meanwhile, the lateral adjustment mechanism 7 drives the lifting mechanism 5 to adjust to a suitable position. The lifting mechanism 5 drives the L-shaped quadrangular prism 504 to adjust to a suitable position (the working principle of the lifting mechanism 5 is as described above). Then, the first threaded rod 602 and the second threaded rod 6 of the clamping mechanism 6 on one side of the L-shaped quadrangular prism 504 are used. 03 moves towards the center, driving the clamping plate 605 and clamping gasket 606 to move towards the center to clamp and fix the threaded flange (the working principle of the clamping mechanism 6 is as described above), preventing damage or affecting quality. The lifting mechanism 5 and the clamping mechanism 6 can clamp the threaded flange as the threaded flange at the top of the fixing mechanism 3 moves, moving the threaded flange up and down to fix and position it. Then, the impurities generated during processing are collected using the collection and cleaning box 4 to improve production efficiency. They are then manually removed and disposed of. After the clamping mechanism 6 stops clamping, the threaded flange is removed using the drive motor 303.

[0038] The working modes are as follows: First, the threaded flange is manually rotated and fixed by the drive motor 303 at the bottom of the fixing mechanism 3, which drives the threaded part of the drive shaft 301 to engage with the threaded flange (the working principle of the fixing mechanism 3 is as described above). Multiple threaded flanges can be placed on the top of the drive shaft 301 for drilling. Second, the threaded rod is driven by the lifting motor of the lifting mechanism 5, and the thread at the bottom of the L-shaped quadrangular prism 504 engages with the threaded rod 503. The lifting motor 502 drives the threaded rod 503 to a height higher than the fixing mechanism 3 (the working principle of the lifting mechanism 5 is as described above). Then, the horizontal adjustment mechanism 7 moves the clamping mechanism 6 to clamp threaded flanges of different sizes and perform drilling. Third, the lifting mechanism 5 drives the clamping mechanism 6 to assist the fixing mechanism 3 in fixing the threaded flange, and the clamping mechanism 6 can move up and down to perform drilling.

[0039] In summary, by utilizing the above-mentioned technical solution of this utility model, threaded flanges are prepared by selecting suitable materials and performing pre-treatment steps such as drilling and orifice treatment, followed by positioning processing. By setting up a fixing mechanism 3, a lifting mechanism 5, a clamping mechanism 6, and a lateral adjustment mechanism 7, the threaded flange is fixed using the thread of the drive shaft of the fixing mechanism and moved to the appropriate clamping position, reducing manual intervention. Then, the lifting mechanism 5 and the clamping mechanism 6 cooperate with the fixing mechanism 3 to perform vertical movement to fix the threaded flange, and the lifting mechanism 5 moves towards the center to reduce slippage of the threaded flange and improve accuracy. The inclusion of a collection and cleaning box 4 collects impurities generated during the processing of the fixed threaded flange, improving work efficiency without affecting positioning accuracy.
