Technical Field

[0001] The utility model relates to the technical field of flange processing equipment, and more specifically, to a turnover mechanism for flange processing. Background Art

[0002] Flange, also known as flange flange or flange, is a part that connects shafts to each other and is used to connect pipe ends. There are holes on the flange, and bolts connect the two flanges tightly. The flanges are sealed with gaskets. Flanges are divided into threaded flanges, welding flanges and clamping flanges.

[0003] When flanges are produced and processed, a corresponding flipping mechanism is often required to help operators process the flanges at different angles. The existing flipping mechanism is generally provided with a corresponding fixed structure so that the flange will not fall due to flipping. However, the existing fixed structure is generally adjusted manually by the operator. This method not only increases the labor intensity of the operator, but also reduces the efficiency of the operator's production and processing. Therefore, it needs to be improved.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 5 As shown, the utility model provides a turning mechanism for flange processing, comprising:

[0028] A base 1, support plates 2 are fixedly installed on both sides of the top of the base 1, the number of the support plates 2 is two, a central shaft 3 is movably sleeved between the two support plates 2, and a flip plate 4 located between the support plates 2 is fixedly sleeved on the outer surface of the central shaft 3;

[0029] The number of the fixing plates 5 is two, and the two fixing plates 5 are respectively fixedly installed at the front and rear sides of the right side of the top of the flip plate 4, and a fixing rod 8 is fixedly installed between the two fixing plates 5;

[0030] A fixing fixture 12, the fixing fixture 12 is fixedly mounted on the left side of the top of the flip plate 4;

[0031] A clamping mechanism, which is arranged on the upper surface of the flip plate 4;

[0032] Among them, the clamping mechanism includes a first motor 6, which is fixedly installed on the back of the fixed plate 5, and the other end of the output shaft of the first motor 6 is fixedly sleeved with a threaded rod 7, the other end of the threaded rod 7 penetrates the fixed plate 5 and extends between the fixed plates 5, the outer surface of the threaded rod 7 is threadedly sleeved with a slider 9 located between the fixed plates 5, the interior of the slider 9 is movably sleeved with the outer surface of the fixed rod 8, the left side of the slider 9 is hinged with a connecting rod 10, the other end of the connecting rod 10 is hinged with a movable clamp 11, the bottom of the movable clamp 11 is movably connected to the top of the flip plate 4, and the movement of the slider 9 causes the connecting rod 10 to push the movable clamp 11 forward to clamp the fixed flange.

[0033] When the first motor 6 is started, the threaded rod 7 will rotate. At this time, since the threaded rod 7 and the slider 9 are threadedly connected, the slider 9 moves linearly along the outer surface of the threaded rod 7, so that the connecting rod 10 will push the movable clamp 11 forward to clamp the fixed flange, thereby achieving the purpose of automatically clamping the fixed flange.

[0034] A second motor 15 is fixedly mounted on the right side of the top of the base 1 , a rotating shaft 16 is fixedly sleeved on the other end of the output shaft of the second motor 15 , and a driving wheel 17 is fixedly sleeved on the outer surface of the rotating shaft 16 .

[0035] When the second motor 15 is started, the rotating shaft 16 drives the driving wheel 17 to rotate.

[0036] The right end of the central shaft 3 penetrates the support plate 2 and extends to the outside of the support plate 2 and is fixedly sleeved with a driven wheel 18 , which is connected to the driving wheel 17 through a transmission belt 19 .

[0037] When the driving wheel 17 rotates, the driven wheel 18, the central shaft 3 and the flip plate 4 are driven to rotate as a whole through the transmission belt 19, thereby realizing the flipping and tilting function of the flange, so that the operator can process it at different angles.

[0038] A limiting groove 13 is provided in the middle of the top of the flip plate 4 , and a limiting block 14 is movably sleeved inside the limiting groove 13 . The top of the limiting block 14 is fixedly connected to the bottom of the movable clamp 11 .

[0039] Due to the cooperation between the limiting groove 13 and the limiting block 14 , a good limiting effect can be achieved on the movement of the movable clamp 11 .

[0040] An angle ruler 21 is fixedly installed in the middle of the left side of the support plate 2, and a pointer 20 located inside the angle ruler 21 is fixedly installed at the left end of the central axis 3. The pointer 20 rotates along with the central axis 3 to indicate the rotation angle.

[0041] When the central shaft 3 rotates, the pointer 20 is driven to rotate. At this time, the scales corresponding to the pointer 20 and the angle ruler 21 can be converted into the degree of flipping of the flip plate 4, thereby realizing the control of the flip angle.

[0042] The right side of the fixed clamp 12 and the left side of the movable clamp 11 are both arc-shaped, and the right side of the fixed clamp 12 and the left side of the movable clamp 11 are rough.

[0043] Since the inner surfaces of the movable clamp 11 and the fixed clamp 12 are rough, the movable clamp 11 and the fixed clamp 12 play a good auxiliary role in the subsequent clamping and fixing of the flange.

[0044] There are circular holes on both sides of the slider 9 , and the inner surfaces of the circular holes and the outer surface of the fixing rod 8 are both smooth.

[0045] Since the circular hole inside the slider 9 and the outer surface of the fixing rod 8 are both smooth, the slider 9 can move more smoothly on the surface of the fixing rod 8 .

[0046] The working principle and use process of this utility model:

[0047] First, the operator fits the flange against the outer surface of the right side of the fixed clamp 12, and then starts the first motor 6, which will cause the threaded rod 7 to rotate. At this time, the slider 9 moves forward, and the connecting rod 10 hinged on its side will push the movable clamp 11 to move to the left. Finally, the fixed flange will be clamped between the movable clamp 11 and the fixed clamp 12.

[0048] When the operator needs to perform tilting processing on the flange, the second motor 15 is started, the rotating shaft 16 will drive the driving wheel 17 to rotate, and then drive the driven wheel 18, the center axis 3, the flip plate 4 and the pointer 20 to rotate together through the transmission belt 19. The rotation of the pointer 20 will correspond to the angle value on the indicating angle scale 21, so that the operator can adjust the tilt angle of the flip plate 4 and the flange according to the needs to facilitate subsequent processing operations.
