[0004] When the positioning tool in the above technology positions the flange, due to the fixed arc shape of the first clamping plate and the second clamping plate, when fixing, the first clamping plate and the second clamping plate can only fit with the outer wall of the flange when they are combined to form a circle. Otherwise, only the middle part of the first clamping plate and the second clamping plate are in contact with the flange, and the flange is easily displaced during processing force. Therefore, the current positioning tool is only suitable for fixing flanges of one size.

[0005] Therefore, in order to solve the above problems, a flange processing and positioning tool is proposed. Utility Model Content

[0013] Beneficial effects of the utility model:

[0014] The utility model provides a flange processing positioning tool. The flange is placed on a disc by arranging a gear and a gear ring. In order to solve the problem that the current positioning tool is only suitable for fixing a flange of one size, it is necessary to rotate a first rotary block. The first rotary block drives the gear to rotate. Since the gear is meshed with the gear ring, the gear drives the gear ring to rotate, and the gear ring drives the disc to rotate. During the rotation of the disc, the disc drives the arc-shaped mouth to rotate. The arc-shaped mouth contacts with a first limiting column. Therefore, during the rotation of the arc-shaped mouth, the arc-shaped mouth presses the first limiting column. The first limiting column rotates with the rotation of the arc-shaped mouth. Because the bottom of the first limiting column is constrained by a slide rail, the first limiting column synchronously contracts inwardly along the slide rail.

When the inner wall of the flange needs to be positioned, the second rotary block is rotated, and the second rotary block drives the screw rod to rotate. During the rotation of the screw rod, the lifting block is threadedly connected to the screw rod through a nut seat, so the lifting block performs a lifting movement. The lifting block drives one end of a connecting rod to move up and down through a pin shaft. Since the other end of the connecting rod is rotatably connected to the second limiting column through the pin shaft, the connecting rod pushes the second limiting column to move through this end. When the second limiting column is in close contact with the inner wall of the flange, the rotation is stopped, so that the inner wall of the flange is positioned, which is convenient for processing the outer wall of the flange.

[0025] 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 of 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.

[0026] Specific examples are given below.

[0027] See also Figure 1-Figure 6 The utility model provides a flange processing positioning tool, comprising a workbench 1; the top of the workbench 1 is slidably connected to a mounting frame 2 through an electric guide rail; a processing equipment body 3 is installed on the mounting frame 2; the top of the workbench 1 is rotatably connected to a disc 4 through a rotating shaft, and eight arc-shaped openings 6 are arranged circumferentially on the disc 4; first limiting columns 5 are slidably connected in the arc-shaped openings 6; slide rails 16 are provided below the first limiting columns 5; the top of the workbench 1 is rotatably connected to a pillar 8 through a bearing, a gear 9 is fixedly connected to the top of the pillar 8, a first rotating block 15 is fixedly connected to the top of the gear 9, a gear ring 7 is fixedly connected to the outer wall of the disc 4, and the gear ring 7 is meshed with the gear 9; a limiting component is provided below the gear 9, and the limiting component is used to prevent the gear 9 from rotating.

[0028] During operation, the flange is placed on the disc 4. In order to solve the problem that the current positioning tool is only suitable for fixing flanges of one size, it is necessary to rotate the first rotary block 15. The first rotary block 15 drives the gear 9 to rotate. Since the gear 9 is meshed with the gear ring 7, the gear 9 drives the gear ring 7 to rotate, and the gear ring 7 drives the disc 4 to rotate. During the rotation of the disc 4, the disc 4 drives the arc-shaped opening 6 to rotate. The arc-shaped opening 6 contacts the first limiting column 5. Therefore, during the rotation of the arc-shaped opening 6, the arc-shaped opening 6 presses the first limiting column 5. The first limiting column 5 rotates with the rotation of the arc-shaped opening 6. Because the bottom of the first limiting column 5 is constrained by the slide rail 16, the first limiting column 5 synchronously shrinks inward along the slide rail 16. When the first limiting column 5 is in close contact with the flange, the limiting assembly is driven to prevent the self-rotation of the gear 9 from affecting the stability of the first limiting column 5, so as to realize the fixing function of flanges of different sizes; then the mounting frame 2 and the processing equipment body 3 are moved to a suitable position by the electric guide rail, and the processing equipment body 3 is started for processing.

[0029] Further, such as Figure 2 and Figure 3 As shown, the limiting assembly includes a ratchet 10 fixedly connected to the outer side wall of the pillar 8; a pawl 11 is provided on one side of the ratchet 10, the ratchet 10 cooperates with the pawl 11, one end of the pawl 11 is fixedly connected to a pressure block 12, a sliding column 13 is slidably connected to the pressure block 12, the sliding column 13 is fixedly connected to the top of the workbench 1, the outer side wall of the sliding column 13 is sleeved with a spring 14, the top of the spring 14 is fixedly connected to the bottom of the pressure block 12, and the bottom of the spring 14 is fixedly connected to the workbench 1.

[0030] During operation, when it is necessary to drive the gear 9, the pressure block 12 is pressed downward, and the pressure block 12 drives the pawl 11 to move downward. The spring 14 is compressed, and the pawl 11 releases the fixation of the ratchet 10, and the first rotary block 15 can be rotated, and the first rotary block 15 drives the gear 9 to rotate; when the first limiting column 5 moves to a suitable position, the pressure block 12 is released, and under the action of the spring 14, the pressure block 12 moves upward, and the pressure block 12 drives the pawl 11 to move upward, and the pawl 11 moves upward to cooperate with the ratchet 10 to limit the rotation of the ratchet 10, thereby limiting the rotation of the support 8 and the gear 9, and achieving the stability of the first limiting column 5.

[0031] Further, such as Figure 4 As shown, the bottom of each of the first limiting columns 5 is fixedly connected with a slider, each of the sliders is slidably connected to a slide rail 16 , and each of the slide rails 16 is fixedly connected to the workbench 1 .

[0032] During operation, when the first limiting column 5 is in motion, the first limiting column 5 drives the slider to move, and the slider slides on the slide rail 16 . The slider limits the first limiting column 5 on the slide rail 16 to prevent the first limiting column 5 from rotating due to the pressure of the arc-shaped opening 6 .

[0033] Further, such as Figure 5 and Figure 6 As shown, a groove 17 is opened in the middle of the disc 4, and a screw rod 18 is rotatably connected in the groove 17 through a bearing; a second rotating block 19 is fixedly connected to the top of the screw rod 18, and a lifting block 23 is threadedly connected to the outer wall of the screw rod 18, and four connecting rods 21 are rotatably connected to the outer wall of the lifting block 23 through a pin; four second limiting columns 20 are arranged on the outer circumference of the screw rod 18, and one end of the connecting rod 21 is rotatably connected to the second limiting column 20 through a pin.

[0034] During operation, when it is necessary to position the inner wall of the flange, the second rotary block 19 is rotated, and the second rotary block 19 drives the screw rod 18 to rotate. During the rotation of the screw rod 18, since the lifting block 23 is threadedly connected to the screw rod 18 through the nut seat, the lifting block 23 performs lifting movement. The lifting block 23 drives one end of the connecting rod 21 to lift and lower through the pin shaft. Since the other end of the connecting rod 21 is rotatably connected to the second limit column 20 through the pin shaft, the connecting rod 21 pushes the second limit column 20 to move through this end. When the second limit column 20 is in close contact with the inner wall of the flange, it stops rotating to achieve the positioning of the inner wall of the flange, which is convenient for processing the outer wall of the flange.

[0035] Further, such as Figure 6 As shown, the bottom of the second limiting column 20 is fixedly connected to the limiting block 22, and the bottom inner wall of the groove 17 is provided with four limiting grooves, and the limiting blocks 22 are slidably connected in the limiting grooves.

[0036] During operation, when the second limiting column 20 moves, the second limiting column 20 drives the limiting block 22 to move, and the second limiting block 22 slides in the limiting groove, and the limiting block 22 limits the second limiting column 20 in the horizontal direction.

[0037] Further, such as Figure 5 As shown, the arc-shaped openings 6 are all opened in a divergent shape, and the arc-shaped openings 6 are used to push the first limiting column 5 to perform divergent and contraction movements.

[0038] During operation, the arc-shaped opening 6 is opened in a divergent shape. During the movement of the disc 4, the arc-shaped opening 6 is always in contact with the first limiting column 5 to press the first limiting column 5, thereby pushing the first limiting column 5 to perform divergent and contraction movements.

[0039] Working principle: the flange is placed on the disc 4. In order to solve the problem that the current positioning tool is only suitable for fixing flanges of one size, it is necessary to rotate the first rotary block 15. The first rotary block 15 drives the gear 9 to rotate. Since the gear 9 is meshed with the gear ring 7, the gear 9 drives the gear ring 7 to rotate, and the gear ring 7 drives the disc 4 to rotate. During the rotation of the disc 4, the disc 4 drives the arc-shaped mouth 6 to rotate. The arc-shaped mouth 6 contacts the first limiting column 5. Therefore, during the rotation of the arc-shaped mouth 6, the arc-shaped mouth 6 presses the first limiting column 5. The first limiting column 5 rotates with the rotation of the arc-shaped mouth 6. Because the bottom of the first limiting column 5 is constrained by the slide rail 16, the first limiting column 5 synchronously retracts inward along the slide rail 16. When the first limiting column 5 is in close contact with the flange, the pressure on the pressure block 12 is released. Under the action of the spring 14, the pressure block 12 moves upward, and the pressure block 12 drives the pawl 11 to move upward. The pawl 11 moves upward and cooperates with the ratchet 10 to limit the rotation of the ratchet 10, thereby limiting The rotation of the pillar 8 and the gear 9 realizes the stability of the first limit column 5, prevents the self-rotation of the gear 9 from affecting the stability of the first limit column 5, and realizes the fixing function of flanges of different sizes; then the mounting frame 2 and the processing equipment body 3 are moved to a suitable position by the electric guide rail, and the processing equipment body 3 is started for processing; when it is necessary to position the inner wall of the flange, the second rotary block 19 is rotated, and the second rotary block 19 drives the screw rod 18 to rotate. During the rotation of the screw rod 18, since the lifting block 23 is threadedly connected to the screw rod 18 through the nut seat, the lifting block 23 performs lifting movement, and the lifting block 23 drives one end of the connecting rod 21 to lift and lower through the pin shaft. Since the other end of the connecting rod 21 is rotatably connected to the second limit column 20 through the pin shaft, the connecting rod 21 pushes the second limit column 20 to move through this end, and when the second limit column 20 is in close contact with the inner wall of the flange, the rotation stops, and the positioning of the inner wall of the flange is realized, which is convenient for processing the outer wall of the flange.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
