Description

Technical Field

[0001] This utility model relates to the field of flange production technology, specifically to a flange leveling machine. Background Technology

[0002] Flanges are common connecting components in piping systems, typically used to connect pipes, valves, pumps, compressors, and other equipment. Their function is to allow different pipe components to be connected by bolts, forming a sealed connection. The flange manufacturing process involves multiple steps, including material selection, processing, heat treatment, and quality control.

[0003] Flange leveling machines are commonly used equipment in flange production. A motor drives a leveling rod to rotate, and the rollers or pressure rollers on the leveling rod rotate and roll the flange placed on the worktable. By using the friction and pressure between the rollers and the flange surface, the unevenness of the flange surface is gradually leveled, so that the flange has a flat surface.

[0004] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. When using some existing ordinary flange leveling machines, the worktable may accidentally collide with the pressure roller when the height of the worktable is adjusted. This collision not only damages the structural integrity of the worktable but may also cause wear, deformation, and other damage to the pressure roller, thereby affecting the normal use and leveling accuracy of the flange leveling machine; 2. When using some existing ordinary flange leveling machines, the worktable will rotate along with the flange placed on it. When the worktable is rotating, the operator may accidentally come into contact with the worktable if they are not careful. This accidental contact is very likely to cause personal injury to the operator. Utility Model Content

The L-shaped frame, mounting plate, swivel wheel, reducer, first geared motor, first transmission wheel, second transmission wheel, and belt are symmetrically distributed about the vertical center line of the top plate.

[0009] More preferably, the rotating assembly includes a housing slidably mounted on the outer wall of the support column, a rotating rod rotatably mounted through the top of the housing, a worktable mounted on the top of the rotating rod, an mounting ring mounted on the bottom of the worktable, a gear ring mounted on the inner wall of the mounting ring, a second reduction motor mounted on the top of the inner wall of the housing, and a gear mounted on the output end of the second reduction motor, the gear meshing with the gear ring.

[0010] More preferably, the top of the hydraulic push rod is connected to the bottom of the housing, and the hydraulic push rods are symmetrically distributed about the vertical center line of the housing.

[0011] More preferably, the fixing plate is installed on the top of the box body, and the limiting plate is installed on the bottom of the top plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, when the height of the worktable is adjusted, the fixed plate and the limiting block are moved simultaneously by the limiting component. The limiting block slides in the elliptical hole of the limiting plate, which can limit the range of movement of the limiting block and prevent the limiting block from moving excessively upward, thereby limiting the worktable and preventing it from colliding with the leveling wheel when the worktable moves upward, causing damage to the worktable or the leveling wheel, and improving the safety of the equipment during use.

[0016] In this invention, when using a flange leveling machine, the electric push rods of the two protective components are simultaneously activated by a synchronizer. The two electric push rods drive the corresponding arc-shaped protective frames to move downwards, so that the two arc-shaped protective frames cover the moving mechanism of the rotating component from the front and rear ends. This can prevent the operator from accidentally contacting or colliding with the rotating worktable, thus preventing injury to the operator and improving the safety of the equipment during use.

[0024] Please see Figures 1 to 5 The present invention provides a technical solution: a flange leveling machine, including a support assembly 1, a rotating assembly 2 slidably installed on the inner wall of the support assembly 1, a limit assembly 3 installed on the top of the rotating assembly 2, and protective assemblies 4 installed at both the front and rear ends of the support assembly 1.

[0025] The limiting component 3 includes a fixing plate 301 and a limiting plate 302, and a limiting block 303 is installed on one side of the fixing plate 301.

[0026] The protective component 4 includes a connecting plate 401, an electric push rod 402 is installed through the top of the connecting plate 401, a slide rod 403 is slidably installed through the top of the connecting plate 401, and an arc-shaped protective frame 404 is installed at the bottom of the electric push rod 402.

[0027] In this embodiment, as Figure 2 As shown, the support assembly 1 includes a base plate 101. Support columns 102 are installed on the top of the base plate 101 and near its four corners. A top plate 103 is installed on the top of the support columns 102. L-shaped frames 104 are installed on both sides of the top plate 103. A mounting plate 105 is installed on the bottom of the top plate 103. A swivel wheel 106 is rotatably mounted on one side of the mounting plate 105, and the mounting plates 105 are symmetrically distributed about the vertical center line of the swivel wheel 106. A reducer 107 and a first geared motor 108 are installed on the bottom inner wall of the L-shaped frame 104. A first transmission wheel 109 is installed at the input end of the reducer 107, and a second transmission wheel 1010 is installed at the output end of the first geared motor 108. A belt 1011 is attached to the outer wall of the second transmission wheel 1010. The top of the base plate 101... The unit is equipped with a hydraulic push rod 1012, and a belt 1011 is attached to the outer wall of the first transmission wheel 109. The output end of the reducer 107 is connected to the leveling wheel 106. The L-shaped frame 104, mounting plate 105, leveling wheel 106, reducer 107, first reduction motor 108, first transmission wheel 109, second transmission wheel 1010 and belt 1011 are symmetrically distributed about the vertical center line of the top plate 103. When the two first reduction motors 108 are started, they drive the second transmission wheel 1010 to rotate. When the second transmission wheel 1010 rotates, it drives the first transmission wheel 109 through the belt 1011. When the first transmission wheel 109 rotates, it drives the leveling wheel 106 to rotate through the reducer 107. The two leveling wheels 106 rotate in opposite directions, which can level the flange.

[0028] In this embodiment, as Figure 2 and Figure 3 As shown, the rotating assembly 2 includes a housing 201 slidably mounted on the outer wall of the support column 102. A rotating rod 202 is rotatably mounted through the top of the housing 201. A worktable 203 is mounted on the top of the rotating rod 202. An installation ring 204 is mounted on the bottom of the worktable 203. A gear ring 205 is mounted on the inner wall of the installation ring 204. A second reduction motor 206 is mounted on the top of the inner wall of the housing 201. A gear 207 is mounted on the output end of the second reduction motor 206. The gear 207 meshes with the gear ring 205. When the second reduction motor 206 is started, the gear 207 drives the gear ring 205, the worktable 203, the installation ring 204, and the rotating rod 202 to rotate, thereby driving the flange placed on the top of the worktable 203 to rotate, improving the flatness of the flange.

[0029] In this embodiment, as Figure 2 and Figure 3 As shown, the top of the hydraulic push rod 1012 is connected to the bottom of the housing 201, and the hydraulic push rods 1012 are symmetrically distributed about the vertical center line of the housing 201. When the two hydraulic push rods 1012 are started at the same time, they can drive the rotating component 2 to move up and down. The distance between the worktable 203 and the swivel wheel 106 can be adjusted according to the thickness of the flange to improve the applicability of the equipment.

[0030] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the fixing plate 301 is installed on the top of the housing 201, and the limiting plate 302 is installed on the bottom of the top plate 103. An elliptical hole is provided on one side of the limiting plate 302, and the sliding rod of the limiting block 303 is installed in the elliptical hole of the limiting plate 302. The limiting components 3 are symmetrically distributed about the vertical center line of the top plate 103. The swivel wheel 106 consists of a swivel rod and a pressure wheel. The pressure wheel is installed on the outer wall of the swivel rod. When the housing 201 is driven upward by the hydraulic push rod 1012, the fixing plate 301 and the limiting block 303 are driven upward. The limiting block 303 slides in the elliptical hole of the limiting plate 302. The elliptical hole of the limiting plate 302 can limit the movement range of the limiting block 303, thereby limiting the worktable 203 and preventing the worktable 203 from moving too far upward and colliding with the swivel wheel 106, causing damage.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 5As shown, the connecting plate 401 is installed on the outer wall of the top plate 103, and the sliding rod 403 is installed on the top of the arc-shaped protective frame 404. The sliding rods 403 are symmetrically distributed about the vertical center line of the arc-shaped protective frame 404, and the arc-shaped protective frame 404 and the electric push rod 402 constitute a lifting mechanism. When the electric push rod 402 is started, it can drive the arc-shaped protective frame 404 to move up and down. The two sliding rods 403 can improve the stability of the arc-shaped protective frame 404 when it moves up and down. When the arc-shaped protective frame 404 covers the moving mechanism of the rotating component 2, it can play a protective role when the equipment is in use, preventing the operator from accidentally touching the moving mechanism of the rotating component 2 and causing injury to the operator.

[0032] In this embodiment, as Figure 5 As shown, the inner wall of the arc-shaped protective frame 404 is provided with arc-shaped protective glass, and the protective components 4 are symmetrically distributed about the vertical center line of the top plate 103. The two electric push rods 402 are started simultaneously by a synchronizer. When the two electric push rods 402 drive the arc-shaped protective frame 404 to move down, they cover the movement mechanism of the rotating component 2 from the front and rear ends, which can play a protective role. At the same time, the equipment can be seen to see the leveling of the flange through the protective glass on the arc-shaped protective frame 404.

[0033] The usage and advantages of this utility model: The flange leveling machine operates as follows:

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first, the flange to be leveled is placed on top of the workbench 203. Then, the hydraulic push rod 1012 is activated, causing the rotating assembly 2, the fixed plate 301, and the limiting block 303 to move upward. The limiting block 303 slides within the elliptical hole of the limiting plate 302. When adjusted to the appropriate position, the hydraulic push rod 1012 is stopped, and the two electric push rods 402 are activated. The electric push rods 402 cause the arc-shaped protective frame 404 to move downward, so that the two arc-shaped protective frames 404 cover the rotating assembly 2 from both the front and rear ends. The actuator then starts the first reduction motor 108 and the second reduction motor 206. The second reduction motor 206 drives the gear ring 205, the worktable 203, the mounting ring 204 and the rotating rod 202 to rotate through the gear 207, thereby driving the flange placed on the top of the worktable 203 to rotate. The two first reduction motors 108 drive the corresponding leveling wheel 106 to rotate through the corresponding second transmission wheel 1010, belt 1011, first transmission wheel 109 and reducer 107 to level the flange.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
