Description

Technical Field

[0001] This invention belongs to the technical field of arc welding equipment, specifically relating to a shot blasting machine housing welding equipment and its usage method. Background Technology

[0002] In the manufacturing process of shot blasting machines, shell welding is one of the core processes, and its welding quality and efficiency directly affect the structural strength, service life, and production capacity of the shot blasting machine. Currently, most shot blasting machine shell welding adopts electric arc welding technology. This process uses the electric arc generated between the electrode and the workpiece to melt the welding wire and the base material to form a weld. It has extremely high requirements for the stability of the electric arc, the accuracy of the welding wire feeding, and the accuracy of the workpiece positioning during the welding process. However, the existing equipment used for shot blasting machine shell welding in the industry has significant shortcomings in adapting to the requirements of electric arc welding technology, making it difficult to meet the requirements of modern production for precision, efficiency, environmental protection, and flexibility.

[0003] Shot blasting machine housings come in various specifications, with significant differences in size and weld position between different models. Arc welding requires precise adjustment of the workpiece and welding torch position based on the weld location, and traditional equipment's workpiece placement and adjustment structures have obvious limitations. Firstly, adjusting the distance between the workpiece and welding torch often relies on manual workpiece handling or pushing of simple supports, which is not only physically demanding but also difficult to precisely control the displacement. Arc welding is extremely sensitive to the distance to the welding torch; even slight deviations can lead to arc instability, resulting in insufficient weld penetration or undercut. This is especially true for large shot blasting machine housings, where manual adjustment is time-consuming and labor-intensive, and distance deviations can easily cause weld position shifts, requiring repeated re-welding. Secondly, angle adjustment capabilities are weak; most equipment can only achieve single-angle fixed welding or requires disassembling and reassembling the workpiece to adjust the angle, failing to quickly adapt to the arc welding needs of complex welds (such as circumferential welds or inclined welds). For example, when welding circumferential welds on a housing, the workpiece angle needs continuous adjustment to ensure the arc is perpendicular to the weld. Traditional equipment's adjustment methods are not only inefficient but also prone to arc instability due to angle fluctuations, affecting weld quality. In addition, most of the workpiece placement components are fixed structures that can only fit housings of specific sizes. When changing to housings of different specifications, the entire placement fixture needs to be replaced, which is not only costly but also significantly extends the production preparation time, thus having shortcomings in use.

[0014] A method for using a shot blasting machine housing welding equipment, wherein the welding equipment is used to weld the shot blasting machine, and the steps are as follows: S1: Before use, check that the base plate, legs and connecting parts are not loose or deformed, and that the robotic arm, welding gun, wire feeding mechanism, control box, suction fan and electric suction cup are operating and connected normally. Clean the top surface of the base plate, the workpiece placement area and welding area of ​​debris and oil stains. Prepare matching bolts, wrenches, connecting pipes and welding wire. Check the filter equipment to ensure that the fume treatment channel is unobstructed. S2: Placement and installation of components. Place the fixing plate on the top surface of the cylinder, align the through hole with the first threaded hole vertically, and screw the bolt through the through hole into the first threaded hole to fix the connector and angle adjustment component. Select the support block according to the workpiece size requirements and insert it into the slot of the long block. Test the adsorption and release function of the electric suction cup to confirm that the connector block and the long block are reliably fixed. S3: Workpiece positioning and fixing. Rotate the rotating block of the screw to make the two screws rotate synchronously, driving the moving block, frame and upper components to move. Adjust the initial distance with the welding gun, place the shot blasting machine housing part to be welded on the top surface of the electric suction cup, adjust the workpiece to align the splice, and start the electric suction cup to adsorb and fix the workpiece. S4: Fine adjustment of angle and position. Loosen the bolts fixing the disc on the horizontal plate, rotate the disc to rotate the placed components and workpiece to adjust the welding angle, so that the welding gun is aligned with the welding joint. Rotate the disc to align the mating hole with the second threaded hole vertically. Tighten the disc by passing the bolt through the mating hole and screwing it into the second threaded hole. Adjust the position of the frame by using the screw to drive the moving block through the screw, so that the distance between the workpiece welding point and the welding gun meets the requirements of arc welding. S5: Welding operation. In sequence, turn on the power to the control box, wire feeding mechanism, robotic arm, and suction fan, and turn on the filtration equipment. Set the welding parameters through the control box, start the robotic arm to test the movement trajectory of the welding torch, connect one end of the connecting pipe to the box pipe and the other end to the filtration equipment, start the suction fan to check the fume absorption channel, and start the welding program after confirming that everything is correct. The robotic arm drives the welding torch and the wire feeding mechanism to perform arc welding at the joint of the workpiece. Observe the welding torch trajectory, welding wire supply and fume absorption during welding. If there is any abnormality, stop the equipment for troubleshooting. S6: Finishing up after welding. After welding is completed, first turn off the welding torch and wire feeding mechanism, then turn off the power of the robotic arm after it resets, then turn off the suction fan and filter equipment, and finally cut off the main power of the control box, turn off the power of the electric suction cup, remove the workpiece and place it in the designated area to cool, clean the welding torch slag, tidy up the welding wire connecting tube, wipe the equipment parts for dust and debris, check the bolt tightness, clean the filter equipment for dust, check the wear and tear of the robotic arm, welding torch, and electric suction cup, and record the equipment operating status, welding parameters and fault conditions.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: (1) Precise and efficient distance adjustment: Through the dual-screw synchronous drive design of the distance adjustment component, the horizontal displacement of the moving block, frame and the workpiece above can be smoothly controlled, and the distance between the workpiece and the welding gun can be precisely adjusted to meet the welding stroke requirements of different sizes of shot blasting machine housings. There is no need to manually move the workpiece to adjust the position, which reduces the operating intensity while improving the distance adjustment accuracy. (2) Convenient and reliable angle adjustment: The angle adjustment component realizes 360° angle adjustment of the workpiece by rotating the disc. With the evenly distributed mating holes and the threaded holes of the horizontal plate for fixation, the welding angle can be quickly positioned to ensure that the welding gun can be accurately aligned with the weld position. It is especially suitable for the welding needs of complex welds on the shell of shot blasting machine, and solves the problem of inconvenient angle adjustment of traditional equipment. (3) Strong adaptability of the placement component: The connecting parts of the placement component are detachably connected to the cylinder of the angle adjustment component by bolts. The support block can be flexibly inserted into different slots of the long block according to the size and shape of the workpiece, so as to realize the free adjustment of the support position. At the same time, the electric suction cup can stably adsorb the shot blasting machine shell workpieces of various materials, which not only ensures the firmness of the workpiece fixation, but also avoids the damage to the workpiece surface by traditional clamps, and adapts to the placement and fixing needs of shot blasting machine shells of different specifications.

[0018] To better understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1 The following is combined with Figures 1-8 A further description of the shot blasting machine housing welding equipment in Example 1 is provided, such as... Figure 1 As shown, it includes a base plate 1, several support legs 2 are fixedly installed on the bottom surface of the base plate 1, a robotic arm is fixedly installed on one side of the top surface of the base plate 1, a welding gun is installed at the end of the robotic arm, and a workpiece placement part is slidably installed on the top surface of the base plate 1.

[0021] The robotic arm uses existing, well-known equipment, such as the MA1440 welding robot. Components such as the wire feeding mechanism and control box are placed on one side of the base plate 1 (not shown in the figure). The welding method is arc welding. The parts to be welded are placed on the workpiece placement part, and the robotic arm drives the welding gun to move. The welding gun and welding wire work together to weld the workpiece and weld the two workpieces together.

[0022] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the workpiece placement part includes a distance adjustment component, an angle adjustment component, and a placement component. The placement component is detachably mounted on the angle adjustment component, and the angle adjustment component is mounted on the distance adjustment component.

[0023] The placement component is installed onto the angle adjustment component. The distance adjustment component controls the distance between the placement component and the welding torch. The workpiece is placed onto the placement component, and then the angle component is adjusted. The angle adjustment component adjusts the angle of the placement component, thus controlling the angle of the workpiece. Then the welding torch performs the welding operation on the workpiece.

[0024] like Figure 1 As shown, the distance adjustment assembly includes two sets of support blocks 3, which are located at the front and rear ends of the base plate 1 respectively. Each set of support blocks 3 consists of two support blocks. The bottom end of the support block is fixedly connected to the top surface of the base plate 1. A screw 4 is rotatably installed between the two support blocks in each set of support blocks 3. One end of the screw 4 passes through one of the support blocks. Two movable blocks 5 are provided on the top of the base plate 1. A screw hole is opened on one side of the movable block 5. The screw 4 passes through the screw hole. The two movable blocks 5 are fixedly connected by a frame 6. A rotating block is fixedly installed at one end of the screw 4.

[0025] Two support blocks in each support block group 3 are located on both sides of the base plate 1. One of the support blocks in each support block group has a through hole on one side, and a bearing is installed in the through hole. The bearing is connected to the screw 4, that is, the outer wall of the outer ring of the bearing is fixedly connected to the inner wall of the through hole, and the inner wall of the inner ring of the bearing is fixedly connected to the outer circumference of the screw 4. One end of the screw 4 is movably connected to the side of the other support block in each support block group. By rotating the two rotating blocks at the same time, the two screws 4 are controlled to rotate synchronously, and the moving block 5 is controlled to move horizontally along the screw 4, thereby driving the frame 6 to move horizontally.

[0026] like Figure 2 As shown, the angle adjustment component includes a disc 7, a rotating shaft is fixedly installed at the center of the bottom surface of the disc 7, the bottom end of the rotating shaft is rotatably installed on the top surface of the frame 6, several mating holes 8 are opened on the top surface of the disc 7, the several mating holes 8 are evenly distributed around the center of the disc 7, several cylinders 9 are fixedly installed on the top surface of the disc 7, the several cylinders 9 are evenly distributed around the center of the disc 7, and a first threaded hole 10 is opened on the top surface of the cylinders 9.

[0027] The placement component is installed above the disc 7. Rotating the disc 7 causes the placement component above to rotate, adjusting the position of the workpiece so that the welding gun can weld better.

[0028] like Figure 1 and Figure 2 As shown, horizontal plates 11 are fixedly installed on both sides of the frame 6, and a second threaded hole 12 is opened on the top surface of the horizontal plate 11.

[0029] Rotate the disc 7 so that one of the mating holes 8 is above the second threaded hole 12. Then, pass a bolt through the mating hole 8 and insert it into the second threaded hole 12. Rotate the bolt to screw it into the second threaded hole 12. At this point, fix the disc 7 and the disc 7 will no longer rotate. It can be fixed by two bolts or by one bolt. For example, when fixing with two bolts, one bolt is located above the corresponding horizontal plate 11 and passes through the mating hole 8 and is inserted into the second threaded hole 12.

[0030] like Figure 7 As shown, the placement assembly includes a connector and a placement component. The connector is detachably connected to the cylinder 9, and the connector is fixedly connected to the placement component. The placement component is located above the connector.

[0031] Install the connector onto cylinder 9, then install the workpiece onto the placement piece, and use the welding gun and welding wire to weld the workpiece.

[0032] like Figure 6 As shown, the connector includes a fixing plate 13, with several through holes 14 on the top surface of the fixing plate 13, and a connecting block is fixedly installed in the middle of the top surface of the fixing plate 13.

[0033] The connecting block is connected to the placement component. The fixing plate 13 is placed on the top surface of the cylinder 9, and the through hole 14 and the first threaded hole 10 are on the same vertical center line. Then, a bolt is passed through the through hole 14 and inserted into the first threaded hole 10 to connect the fixing plate 13 and the cylinder 9 together, thus completing the connection between the placement component and the angle adjustment component.

[0034] like Figure 8 As shown, the placement component includes a long strip 15 and several support blocks 16. Several slots 17 are opened on the top surface of the long strip 15. The bottom end of the support block 16 can be inserted into the slot 17. An electric suction cup 18 is fixedly installed on the top surface of the support block 16.

[0035] The electric chuck 18 can be either an electro-permanent magnet chuck or an electric magnetic chuck. Depending on the required placement of the workpiece, the support block 16 is inserted into the slot 17, and then the workpiece is placed on the electric chuck 18. The electric chuck 18 will attract the workpiece, and since the electric chuck is located below the workpiece, it will not affect the movement of the welding torch.

[0036] like Figure 6 As shown, a long groove 19 is opened on one side of the long strip block 15, and a lead screw 20 is movably installed in the long groove 19. A box body 21 is set on one side of the long strip block 15. The rear end face of the box body 21 is open. A support plate is fixedly installed at the bottom of one side of the box body 21. The support plate can be inserted into the long groove 19. A threaded hole is opened on one side of the support plate. The lead screw 20 passes through the threaded hole. A pipe is fixedly installed on the front end face of the box body 21. The pipe communicates with the inside of the box body 21. A suction fan is installed inside the box body 21.

[0037] One end of the pipe can be detachably connected to a connecting pipe. One end of the lead screw 20 is movably connected to the inner wall of one side of the long groove 19. A rotary motor is installed on the inner wall of the other side of the long groove 19. The other end of the lead screw 20 is fixedly connected to the output shaft of the rotary motor. During the welding process, the suction fan absorbs the welding fumes into the box 21, and then transports them to the filtration equipment through the pipe before being discharged. During the welding process, this can prevent a large amount of fumes from floating into the air and thus prevent them from affecting the health of the workers.

[0038] A method for using a shot blasting machine housing welding equipment, comprising the following steps: I. Preparations before use Check equipment status: Confirm that the base plate 1, support legs 2 and all connecting parts are not loose or deformed, the robotic arm (MA1440 welding robot) operates flexibly, the welding gun, wire feeding mechanism, control box, suction fan and other components are connected normally, and the electric suction cup 18 is powered on and has a good suction function. Clean the work area: Remove debris and oil stains from the top surface of base plate 1, the workpiece placement area and the welding area to ensure a clean operating environment free of obstacles that may affect welding safety. Prepare auxiliary tools: prepare matching bolts, wrenches, connecting pipes and welding wire, check whether the filtration equipment is working properly, and ensure that the dust treatment channel is unobstructed. II. Component Installation and Debugging Assembly of the connector: Place the fixing plate 13 on the top surface of the cylinder 9 of the angle adjustment assembly, align the through hole 14 on the fixing plate 13 with the first threaded hole 10 on the top surface of the cylinder 9 vertically, pass the bolt through the through hole 14 and screw it into the first threaded hole 10, and after tightening, the connector and the angle adjustment assembly are fixed. Assembly of placement components: Based on the size of the shot blasting machine housing workpiece and welding requirements, select an appropriate number of support blocks 16, insert the bottom end of the support block 16 into the slot 17 of the long strip block 15, and ensure that the support block 16 is installed firmly; check whether the wiring of the electric suction cup 18 is normal, and connect the power supply to test the adsorption and release functions. Secure the entire placement component: Confirm that the connecting block of the connector and the long strip block 15 of the placement component are securely fixed without any looseness, and ensure the overall structure of the placement component is stable. III. Workpiece Positioning and Fixing Adjust the distance adjustment component: Rotate the rotating block at one end of the screw 4 to drive the two screws 4 to rotate synchronously, so that the moving block 5 moves horizontally along the screw 4, thereby adjusting the initial distance between the frame 6 and the upper angle adjustment component, the placement component and the robotic arm welding gun, and reserving space for workpiece placement and welding operation. Workpiece placement and adsorption: Place the shot blasting machine housing component to be welded stably on the top surface of the electric suction cup 18, adjust the position of the workpiece according to the welding splicing requirements, and ensure that the splicing points of the two workpieces to be welded are aligned; start the electric suction cup 18 to adsorb and fix the workpiece to prevent the workpiece from shifting during the welding process. IV. Fine-tuning of angle and position Angle Adjustment: Loosen the bolts fixing the disc 7 on the horizontal plate 11, rotate the disc 7 to rotate the components and workpieces placed above, adjust the angle between the welding surface of the workpiece and the welding torch so that the welding torch can be accurately aligned with the welding joint; after the angle is adjusted, rotate the disc 7 so that one of the mating holes 8 is vertically aligned with the second threaded hole 12 of the horizontal plate 11, pass the bolt through the mating hole 8 and screw it into the second threaded hole 12 to tighten the disc 7 (single bolt or double bolt can be used for fixing, when using double bolts, both sides of the horizontal plate 11 must be fixed accordingly). Final distance calibration: Fine-tune the rotating block again, and use the screw 4 to drive the moving block 5 to fine-tune the position of the frame 6, so that the distance between the workpiece welding point and the welding gun meets the requirements of arc welding and ensures welding accuracy. V. Welding Operation Procedure Equipment startup: Connect the power supply to the control box, wire feeding mechanism, robotic arm and suction fan in sequence, and turn on the filtration equipment; set the welding parameters (such as current, voltage and wire feeding speed) through the control box, start the robotic arm operation program, and test whether the welding torch movement trajectory conforms to the preset welding path. Preparation for fume treatment: Connect one end of the connecting pipe to the pipe of box 21, and the other end to the filter equipment. Start the suction fan and check whether the fume absorption channel is unobstructed to ensure that the fume generated by welding can be effectively absorbed.

[0039] Formal welding: After confirming that all preparations have been completed, start the welding program through the control box. The robotic arm moves the welding torch, and the welding torch works with the wire feeding mechanism to output welding wire. Weld the joint of the workpiece using arc welding. During the welding process, observe the trajectory of the welding torch, the supply of welding wire, and the absorption of fumes in real time. If any abnormality occurs, stop the equipment immediately through the control box, troubleshoot the problem, and then continue the operation. VI. Finishing work after welding Equipment shutdown: After welding is completed, first turn off the welding gun and wire feeding mechanism. After the robotic arm returns to its initial position, turn off the power to the robotic arm, then turn off the suction fan and filtration equipment, and finally disconnect the main power supply to the control box. Workpiece removal: Turn off the power to the electric suction cup 18, release the workpiece from the suction, carefully remove the welded shot blasting machine housing parts, and place them in the designated area to cool. Equipment cleaning and maintenance: Clean the welding slag remaining on the welding torch head, and organize the welding wire and connecting pipes; wipe the dust and debris from the placement components, angle adjustment components and the top surface of base plate 1, check whether the bolts are loose and tighten them in time; clean the dust collected by the filter equipment and keep the equipment and operating environment clean. Equipment inspection and recording: Inspect components such as robotic arms, welding torches, and electric suction cups for wear or malfunctions, and record the operating status, welding parameters, and malfunctions (if any) of the welding equipment to provide a basis for subsequent maintenance.

The bolt passes through the through hole (14) and is screwed into the first threaded hole (10) to complete the fixing of the connector and the angle adjustment component. Select the support block (16) according to the workpiece size requirements and insert it into the slot (17) of the long strip block (15). Test the adsorption and release function of the electric suction cup (18) and confirm that the connector block and the long strip block (15) are fixed reliably. S3: Workpiece positioning and fixing, rotate the rotating block of the screw (4) to make the two screws (4) rotate synchronously, drive the moving block (5), frame (6) and the upper component to move, adjust the initial distance with the welding gun, place the shot blasting machine housing part to be welded on the top surface of the electric suction cup (18), adjust the workpiece to align the splice, and start the electric suction cup (18) to adsorb and fix the workpiece; S4: Fine adjustment of angle and position, loosen the bolts of the fixed disc (7) on the horizontal plate (11), rotate the disc (7) to drive the placement component and workpiece to rotate and adjust the welding angle, so that the welding gun is aligned with the welding joint, rotate the disc (7) to make the mating hole (8) and the second threaded hole (12) vertically aligned, the bolt passes through the mating hole (8) and screws into the second threaded hole (12) to tighten the disc (7), the fine adjustment rotating block drives the moving block (5) through the screw (4) to adjust the position of the frame (6) so that the distance between the workpiece welding point and the welding gun meets the requirements of arc welding; S5: Welding operation, turn on the control box, wire feeding mechanism, robotic arm, and suction fan power in sequence and turn on the filter equipment. Set the welding parameters through the control box, start the robotic arm to test the welding gun movement trajectory, connect one end of the connecting pipe to the box (21) pipe and the other end to the filter equipment, start the suction fan to check the fume absorption channel, and start the welding program after confirming that there are no errors. The robotic arm drives the welding gun and the wire feeding mechanism to perform arc welding at the workpiece splice. Observe the welding gun trajectory, welding wire supply and fume absorption during welding. If there are any abnormalities, stop the equipment for troubleshooting. S6: Finishing up after welding. After welding is completed, first turn off the welding gun and wire feeding mechanism. After the robotic arm is reset, turn off its power. Then turn off the suction fan and filter equipment. Finally, cut off the main power of the control box and turn off the power of the electric suction cup (18). Remove the workpiece and place it in the designated area to cool. Clean the welding gun slag, organize the welding wire connecting pipe, wipe the equipment parts for dust and debris, check the bolt tightness, clean the filter equipment dust, check the wear and tear of the robotic arm, welding gun, and electric suction cup (18), and record the equipment operating status, welding parameters and fault conditions.
