Description

Technical Field

[0001] The utility model relates to the field of flange forgings, in particular to a flange forging positioning device. Background Art

[0002] Flange is an engineering connector, usually an annular flat surface or raised structure, used to tightly connect two parts during assembly and fixed by bolts or welding. Flanges are widely used in various piping systems and equipment to provide reliable connection and sealing. Flanges and pipes are mostly fixed by welding. During welding, in order to maintain the stability of the welding process, it is often necessary to use a clamp to fix the flange. However, the flange has an arc surface all around, and the traditional clamp has fewer contact points when clamping the flange. The flange is easy to loosen and the clamping stability is poor.

[0003] After searching, Chinese patent announcement number: CN217493234U discloses a flange forging positioning device, including a device body, a vertical plate is vertically arranged at the top edge of the device body, and a transmission shaft is installed on the surface of the vertical plate. In the utility model, by setting the positioning block, the first mounting seat, the second mounting seat, the extrusion rod, the first threaded sleeve, the second threaded sleeve, and the bidirectional screw rod, the positioning of the flange forging is facilitated, so that during operation, the staff puts the flange forging on the positioning block, then starts the stepper motor, and then the stepper motor drives the bidirectional screw rod to rotate through the transmission shaft, and then the first threaded sleeve and the second threaded sleeve move on the surface of the bidirectional screw rod, and then under the action of the first mounting seat and the second mounting seat, the extrusion rod drives the positioning block to support outward, so that multiple positioning blocks are in close contact with the inner wall of the flange forging, thereby completing the positioning of the flange forging.

[0033] Reference Figure 1 - Figure 3 The rear surface of the round rod 41 is fixedly connected to the front surface of the machine table 1, the rear surface of the support plate 21 is fixedly connected to the front surface of the rotating rod 42, and the center lines of the support plate 21 and the rotating rod 42 are aligned.

[0034] Reference Figure 1 - Figure 3The rear surface of the limit block 27 is set as an inclined surface. When the inclined surface is squeezed, the limit block 27 will move upward. The limit block 27 passes through and is slidably connected to the lower surface of the slider 22. One end of the limit spring 26 is fixedly connected to the upper surface of the limit block 27, and the other end of the limit spring 26 is fixedly connected to the inner wall of the top of the slider 22. When the limit block 27 moves upward, it will squeeze the limit spring 26 to generate a reaction force. The pull rod 25 passes through and is slidably connected to the upper surface of the slider 22. The limit block 27 is inserted into the inner wall of the limit groove 201, which can limit the slider 22. There are multiple groups of limit grooves 201 to support the upper surface of the plate 21 to be evenly distributed front and back.

[0035] Reference Figure 1 , Figure 3 and Figure 5 The positioning assembly also includes a connecting rod 23, and a clamping block 24 is hinged on the front surface of the connecting rod 23. When the connecting rod 23 rotates, the clamping block 24 will be driven to move, and the center line of the clamping block 24 is aligned with the center line of the rotating rod 42.

[0036] Reference Figure 1 , Figure 3 and Figure 5 The rear surface of the connecting rod 23 is hinged to the front surface of the slider 22. When the slider 22 moves, it will squeeze the connecting rod 23. After being squeezed, the connecting rod 23 will rotate.

The two groups of connecting rods 23 and clamping blocks 24 are symmetrically distributed along the center line of the support plate 21. Pulling the slider 22 will drive the clamping blocks 24 on both sides to move together or open synchronously.

[0037] Reference Figure 1 , Figure 3 and Figure 5 The block 44 is slidably connected to the inner wall of the rotating rod 42, the handle 43 passes through and is slidably connected to the upper surface of the rotating rod 42, the block 46 is set to be gear-shaped, and the slot 401 is opened in the shape of a gear. The block 46 is inserted into the inner wall of the slot 401, which can limit the rotating rod 42. One end of the connecting spring 45 is fixedly connected to the front surface of the block 46, and the other end of the connecting spring 45 is fixedly connected to the inner wall of the front side of the rotating rod 42. When the block 46 moves forward, it will disengage from the slot 401 to release the limit on the rotating rod 42, and the rotating rod 42 can rotate, and when the block 46 moves forward, it will also squeeze the connecting spring 45 to generate a reaction force. The rear surface of the block 44 is fixedly connected to the front surface of the block 46, and the block 44, the block 46 and the handle 43 can move synchronously.

[0038] Reference Figure 1 and Figure 4 The clamping assembly includes a stopper 31, the inner wall of the clamping block 24 is elastically connected to a rubber block 32 through a compression spring 33, the inner wall piston on the front side of the clamping block 24 is connected to a rubber pad 34, the inner wall of the clamping block 24 is in a sealed state, and a positioning round block 35 is fixedly connected to the rear surface of the rubber pad 34. Two groups of rubber pads 34 and positioning round blocks 35 are arranged, and are symmetrically distributed front and back with the center line of the clamping block 24. A protrusion is arranged in the sliding path of the rubber pad 34, which can limit the sliding range of the rubber pad 34 and prevent the rubber pad 34 from detaching from the clamping block 24. The positioning round block 35 is soft in texture.

[0039] Reference Figure 1 and Figure 4 The stopper 31 penetrates and is slidably connected to the right surface of the clamping block 24. The right surface of the stopper 31 is set to a cylindrical shape. The cylindrical part is slidably connected to the right surface of the clamping block 24 and is tightly sealed with the clamping block 24. The rubber block 32 piston is connected to the inner wall of the clamping block 24. When the rubber block 32 moves to the right, it will squeeze the air inside the clamping block 24. The squeezed air will push the two groups of rubber pads 34 and the positioning round block 35 toward the center of the clamping block 24. One end of the compression spring 33 is fixedly connected to the right surface of the rubber block 32, and the other end of the compression spring 33 is fixedly connected to the inner wall on the right side of the clamping block 24. When the rubber block 32 moves to the right, it will squeeze the compression spring 33 to generate a reaction force. The left surface of the rubber block 32 is fixedly connected to the right surface of the stopper 31.

[0040] Working principle: first, hold the flange with one hand and move the flange to the middle position of the front surface of the connecting rod 23, and push the slider 22 backward with the other hand. When the slider 22 is pushed backward, the inclined surface of the limit block 27 will be squeezed, and the limit block 27 will move upward to squeeze the limit spring 26 to generate a reaction force. The limit block 27 moving upward will disengage from the limit groove 201 to release the limit on the slider 22, and the slider 22 will move backward. The backward moving slider 22 will pull the connecting rod 23, and the connecting rod 23 will rotate to drive the clamping blocks 24 on both sides to move toward the center of the support plate 21 and squeeze the flange. Since the two sets of clamping blocks 24 are symmetrically arranged, the flange can be kept in the middle of the support plate 21.

[0041] When the flange is squeezed, the edge of the flange will first contact the stopper 31, and the stopper 31 will be squeezed when contacting the flange. After being squeezed, the stopper 31 will move and drive the rubber block 32 to move synchronously. The moving rubber block 32 will squeeze the air inside the clamping block 24, and the moving rubber block 32 will squeeze the compression spring 33 to generate a reaction force. The squeezed air in the clamping block 24 will push the rubber pad 34 and the stopper 31 to move toward the center of the clamping block 24 to clamp the flange to a limit position.

[0042] After the flange is fixed, align the pipe to be welded with the flange and weld it. During the welding process, if the welding angle needs to be changed, pull the handle 43 forward to drive the block 44 and the block 46 to move forward. The block 46 moving forward will squeeze the connecting spring 45 to generate a reaction force, and the block 46 will also disengage from the slot 401 when moving forward to release the limit. After the limit is released, rotate the rotating rod 42 to drive the positioning assembly, the clamping assembly and the flange to rotate to change the welding angle. After the angle is adjusted, release the handle 43, and the reaction force of the connecting spring 45 will push the block 46, the handle 43, and the block 44 to move backward. The block 46 will be plugged into the slot 401 to limit the rotating rod 42 to maintain the stability of the device.

[0043] After welding is completed, pull the pull rod 25 upward to drive the limit block 27 to move upward and disengage from the limit groove 201 to release the limit on the slider 22. After the limit is released, push the slider 22 forward, and the slider 22 will drive the connecting rod 23 to rotate in the opposite direction. The rotating connecting rod 23 will drive the clamping blocks 24 on both sides to open in the left and right directions, releasing the limit on the flange, and the reaction force of the compression spring 33 will push the rubber block 32 and the stop block 31 to move in the opposite direction. The rubber block 32 moving in the opposite direction will pull the air inside the clamping block 24, thereby driving the rubber pad 34 and the positioning round block 35 to move in the opposite direction and return to the initial position.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
