Description

Technical Field

[0001] The present invention relates to a field, and in particular to an automated processing device and a processing technology for joints without welding. Background Art

[0002] During the installation and connection process of metal pipes, metal pipe joints are generally required to connect the metal pipes. The flanges at both ends of the metal pipe joints are used to seal the pipes at both ends. For thicker pipes, the size of the pipe joints will also change. In order to avoid gaps, large and small pipe joints are usually made of one-piece molding during the production process. The one-piece molding method is usually produced by casting, which has low cost, convenient production, and uniform production specifications. However, due to the casting method, defects (burrs, grooves, sharp edges, etc.) will inevitably appear on the surface of the pipe joints. For this reason, the pipe joints need to be surface treated.

[0003] Prior art, such as a grinding device for pipe joint processing disclosed in China Publication No. CN220902721U, includes a workbench and a pipe joint clamping mechanism, an L-shaped support plate is slidably connected to the right side of the top of the workbench, a drive motor is fixedly connected to the right side of the L-shaped support plate, a hydraulic cylinder is fixedly connected to the right side of the top of the workbench, the output end of the hydraulic cylinder is fixedly connected to the right side of the L-shaped support plate, the output end of the drive motor is connected to a grinding disc mechanism capable of changing size through a moving component, the grinding disc mechanism includes a fixed disc, four long grooves are equidistantly provided on the left side of the fixed disc, the tops of the inner walls of the four long grooves are rotatably connected to adjusting screws, the surfaces of the four adjusting screws are threadedly connected to connecting blocks, and the left sides of the connecting blocks are fixedly connected to fan-shaped grinding blocks by bolts.

[0004] The prior art can clamp the joint by a clamping device, and then grind the surface and the inside of the joint by a grinding disc structure. During the grinding process, in the prior art, a motor or other structure is used to drive the grinding device to rotate (or reciprocate). However, in order to facilitate the connection with pipes of different thicknesses, the thickness of the joints at both ends in the prior art will be different. Therefore, during the grinding process, if the grinding is only performed in one direction, due to the thickness difference, some positions will be ground to (the position where the thickness changes, such as the corner position of the joint in the figure). In addition, in order to reduce the poor connection effect of different welding materials, the existing joints usually put the joint on the end of the pipe and connect the joint to the pipe by expanding the pipe. For this purpose, the inner wall of the joint will have multiple groups of grooves in different directions, and the inner wall of the joint will be roughened. During the grinding process, it is difficult to clean the inside of the groove, and when the inside of the joint is ground, dust will remain in the groove (the bottom of the inner wall of the joint), and in some grooves that are horizontal and vertical, the residual dust will enter the groove, which will affect the subsequent pipe connection.

[0018] By adopting the above technical solution, the inner side of the joint can be easily polished and the dust generated during polishing can be collected.

[0019] A method for automated processing of joints without welding, the process comprising the following steps:

[0020] Step 1: Place the joint into the mounting plate, align the outer ring of the joint with the chuck, and start the clamping cylinder according to the specifications of the joint. The clamping cylinder drives the chuck to move and fix the joint;

[0021] Step 2: Start the drive motor, the drive motor drives the fixed seat to move, pushes the joint to the position of the grinding mechanism, and inserts the inner ring of the joint between the upper fixed plate and the lower fixed plate, so that the grinding head of the lower grinding sheet fits with the inner side of the inner ring;

[0022] Step 3: Then start the grinding motor, which drives the grinding turntable to rotate, and the grinding turntable drives the upper and lower fixed plates to rotate synchronously, and as the speed increases, the centrifugal force drives the upper grinding sheet and the lower grinding sheet to rotate, and a counterweight block is connected to the side of the upper grinding sheet, so that the counterweight block drives the upper grinding sheet to rotate downward, so that the grinding sheet is closely attached to the outer wall of the inner ring, so that the grinding sheet grinds the outer wall of the inner ring, and at the same time, the centrifugal force drives the lower grinding sheet to deviate centrifugally, so that the grinding head of the lower grinding sheet is closely attached to the inner side of the inner ring;

[0023] Step 4: Then the driving motor will continue to drive the installation plate to move, thereby driving the joint to continue to move, and the inner and outer sides of the inner ring are polished synchronously. When it moves to the inner folding surface position, the polishing head of the lower polishing sheet no longer fits the inner wall of the inner ring. Under the action of centrifugal force, the centrifugal force will drive the polishing head to continue to rotate. At this time, the side polishing sheet of the lower polishing sheet fits the inner folding surface first, and the inner folding surface is polished and cleaned. Then the joint continues to move, and the side polishing sheet is separated from the inner folding surface. The lower polishing sheet continues to rotate under the action of centrifugal force, so that the lower polishing sheet fits the inner wall of the outer ring, so that the polishing head polishes the inside of the outer ring to achieve the polishing effect.

At this time, the lower grinding sheet grinds the outer folded surface. After grinding, the lower grinding sheet will be tightly attached to the outer folded surface, and at the same time, it will push the lower grinding sheet to rotate through extrusion, so that the outer wall of the lower grinding sheet fits with the outer side of the outer ring, thereby grinding the outer wall of the outer ring;

[0025] Step six: During the grinding process of the inner wall of the outer ring, the lower grinding disc rotates, causing the fan blades to rotate inward. The fan blades rotate inside the joint, thereby driving the airflow to flow inside the joint. The airflow blows toward the inner wall of the inner ring, and the airflow cleans the dust generated during grinding.

[0026] By adopting the above technical solution

[0027] In summary, the present invention mainly has the following beneficial effects:

[0028] 1. The present invention provides a mounting plate, and when fixing the joint, the position of the chuck is adjusted by the clamping cylinder, so that the joint can be conveniently fixed on the outside or inside, thereby fixing and limiting joints of different specifications and shapes.

[0029] 2. The present invention also has a grinding turntable.

[0047] See also Figures 5 to 8 A grinding motor 401 is connected to the side of the rotating frame 4, and a grinding turntable 5 is connected to the output end of the grinding motor 401. A plurality of grinding mechanisms 6 are installed on the outer wall of the grinding turntable 5. Each grinding mechanism 6 is composed of an upper fixed plate 61 and a lower fixed plate 62.

A counterweight block 701 is connected to the side of the upper grinding sheet 7 close to the mounting plate 3. A grinding structure is installed on the side of the upper grinding sheet 7 close to the central position of the grinding turntable 5. When grinding, under the action of centrifugal force, the counterweight block 7 01 is thrown out, a mounting block 801 and a grinding head 802 are installed on the side of the lower grinding sheet 8 close to the mounting plate 3, a plurality of groups of protruding round edges 803 are installed on the top of the grinding head 802, and grinding cotton 804 is installed between each group of protruding round edges 803, a side grinding sheet 805 is provided on the side of the grinding head 802 away from the protruding round edges 803, a fan blade 806 is connected to the side of the lower grinding sheet 8 away from the grinding head 802, the weight of the mounting block 801 and the grinding head 802 is greater than the weight of the fan blade 806, when grinding, under the action of centrifugal force, the grinding head 802 is thrown out, and the fan blade 806 rotates and is thrown into the middle position of the joint 9, and airflow is generated when the fan blade 806 rotates, and the airflow blows toward the collection bucket 501.

[0048] See also Figure 5 A collecting bucket 501 is installed at the center of the grinding turntable 5, and the collecting bucket 501 can extend to the inside of the joint 9, and an adsorption net 502 is installed inside the collecting bucket 501

[0049] See also Fig.11 The joint 9 is composed of an outer ring 901 and an inner ring 902 . The outer side and the inner side of the connection position between the outer ring 901 and the inner ring 902 are an outer folding surface 903 and an inner folding surface 905 respectively. The inner wall of the inner ring 902 is provided with an inner groove 904 .

[0050] During use, first put the joint 9 into the installation plate 3, align the outer ring 901 of the joint 9 with the chuck 303, and start the clamping cylinder 302 according to the specifications of the joint 9. The clamping cylinder 302 drives the chuck 303 to move and fix the joint 9 (clamped by the outer clamp 305, or squeezed and fixed by the inner clamp 306). Then start the drive motor 102, which drives the fixing seat 2 to move, pushes the joint 9 to the position of the grinding mechanism 6, and inserts the inner ring 902 of the joint 9 between the upper fixing plate 61 and the lower fixing plate 62. The fan blade 806 is pushed to rotate, so that the grinding head 802 of the lower grinding sheet 8 is fitted with the inner side of the inner ring 902, and then the grinding motor 401 is started, and the grinding motor 401 drives the grinding turntable 5 to rotate, and the grinding turntable 5 drives the upper and lower fixed plates to rotate synchronously, and as the speed increases, the centrifugal force drives the upper grinding sheet 7 and the lower grinding sheet 8 to rotate, and the side of the upper grinding sheet 7 is connected with a counterweight block 701, so that the counterweight block 701 drives the upper grinding sheet 7 to rotate downward, so that the upper grinding sheet 7 is closely attached to the outer wall of the inner ring 902, so that the upper grinding sheet 7 grinds the outer wall of the inner ring 902 At the same time, the centrifugal force will drive the lower grinding sheet 8 to deviate centrifugally, so that the grinding head 802 of the lower grinding sheet 8 is closely attached to the inner side of the inner ring 902, and the inner groove 904 is ground. The end of the grinding head 802 is provided with a protruding round edge 803, and the protruding round edge 803 is aligned with the inner groove 904. When the protruding round edge 803 rotates, it will synchronously grind the inner groove 904. Then the driving motor 102 will continue to drive the mounting plate 3 to move, thereby driving the joint 9 to continue to move, and the inner and outer sides of the inner ring 902 are synchronously ground. When it moves to the position of the inner folding surface 905 , the grinding head 802 of the lower grinding sheet 8 is no longer in contact with the inner wall of the inner ring 902. Under the action of centrifugal force, the centrifugal force will drive the grinding head 802 to continue to rotate. At this time, the side grinding sheet 805 of the lower grinding sheet 8 is first in contact with the inner folded surface 905, and the inner folded surface 905 is polished and cleaned. Then, the joint 9 continues to move, and the side grinding sheet 805 is separated from the inner folded surface 905. The lower grinding sheet 8 continues to rotate under the action of centrifugal force, so that the lower grinding sheet 8 is in contact with the inner wall of the outer ring 901, so that the grinding head 802 polishes the inside of the outer ring 901 to achieve the polishing effect;

[0051] Afterwards, the upper grinding sheet 7 grinding the outer wall of the inner ring 902 also continues to move and fits with the outer folded surface 903. At this time, the upper grinding sheet 7 grinds the outer folded surface 903, and after grinding, the upper grinding sheet 7 will be tightly attached to the outer folded surface 903, and at the same time, it will push the upper grinding sheet 7 to rotate by squeezing, so that the outer wall of the upper grinding sheet 7 fits with the outer side of the outer ring 901, thereby grinding the outer wall of the outer ring 901;

[0052] During the process of grinding the inner wall of the outer ring 901, the lower grinding plate 8 rotates, causing the fan blades 806 to rotate inward. The fan blades 806 rotate inside the joint 9, thereby driving the air flow to flow inside the joint 9. The air flow blows toward the inner wall of the inner ring 902. The air flow cleans the dust generated during grinding, preventing dust from remaining in the inner groove 904, thereby improving the cleaning effect.

After grinding, the lower grinding sheet will be tightly attached to the outer folded surface, and at the same time, it will push the lower grinding sheet to rotate through extrusion, so that the outer wall of the lower grinding sheet fits with the outer side of the outer ring, thereby grinding the outer wall of the outer ring; Step six: During the grinding process of the inner wall of the outer ring, the lower grinding disc rotates, causing the fan blades to rotate inward. The fan blades rotate inside the joint, thereby driving the airflow to flow inside the joint. The airflow blows toward the inner wall of the inner ring, and the airflow cleans the dust generated during grinding.
