Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically, to a welding device for processing vibrating screen motors. Background Technology

[0002] Vibrating screens are widely used screening equipment in industries such as mining, metallurgy, coal, building materials, chemicals, and grain processing. They are mainly used for grading, dewatering, demediuming, and impurity removal of various bulk materials. The vibrating screen motor, as the core power component, is responsible for providing stable and reliable excitation force to the entire screening equipment. Its performance directly determines the working efficiency and service life of the vibrating screen. In the manufacturing process of vibrating screen motors, the processing of the motor silicon steel sheets is a crucial step. The motor silicon steel sheets are the fixed part of the motor, working in conjunction with the rotating rotor to complete the conversion of electrical energy into mechanical energy. The motor silicon steel sheets mainly consist of three parts: the iron core, the windings, and the frame. Among them, the iron core is the core component, its function being to form the main magnetic circuit of the motor, providing low magnetic flux density to the internal magnetic field of the motor. The core serves as a channel for resistance and also plays a crucial role in fixing and supporting the binding assembly. Because an alternating magnetic field is generated inside the motor core during operation, to reduce eddy current and hysteresis losses, decrease core heating, and improve motor efficiency, the core is typically not made from a single solid piece of metal. Instead, silicon steel sheets with good magnetic permeability and high resistivity are selected as the raw material. Multiple sets of stamped silicon steel sheets are neatly stacked according to design requirements, and then welded together to form a complete silicon steel core structure. Currently, laser welding technology is widely used in the industry for welding silicon steel cores. Laser welding has advantages such as high energy density, small heat-affected zone, small welding deformation, and good weld quality, which can better meet the requirements of motor cores for welding precision and strength.

[0003] However, existing welding devices for silicon steel sheet cores in vibrating screen motors still have some shortcomings and defects in actual production applications. First, when welding stacked silicon steel sheets, existing welding devices typically use only simple mechanical pressing to fix multiple sets of silicon steel sheets. This fixing method has problems such as uneven distribution of clamping force and poor clamping effect at the edges, which makes it easy for interlayer gaps or local loosening to occur between the stacked silicon steel sheets. During laser welding, the loose silicon steel sheets may experience slight displacement or vibration, resulting in weld misalignment, inconsistent weld depth, and incomplete welds. Firstly, the simple pressing and fixing method is difficult to adapt to the welding requirements of silicon steel sheets of different specifications and sizes. When processing silicon steel sheet cores of different models of motors, it is often necessary to replace the entire pressing fixture or perform cumbersome adjustment operations, resulting in low production efficiency and poor versatility and adaptability. Therefore, there is an urgent need for a welding device for processing vibrating screen motors that can stably and reliably fix silicon steel sheets, has strong adaptability, and provides good welding results, in order to solve the above-mentioned problems in the existing technology and improve the welding quality and production efficiency of motor silicon steel sheet cores.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a welding device for processing vibrating screen motors, which has the following beneficial effects: The present invention constructs a complete silicon steel sheet welding system by setting up a welding table, a moving frame, a laser head, a mounting frame, a motor, a drive wheel, a fixed frame, a rotating sleeve, a follower wheel, and an intermediate shaft. This device can simultaneously perform welding operations on silicon steel sheets stacked on both sides, improving welding efficiency. During welding, the motor drives the drive wheel to rotate, and the drive wheel drives the follower wheel meshing with it to rotate synchronously. The follower wheel drives the intermediate shaft and multiple sets of silicon steel sheets sleeved on the outer wall of the intermediate shaft to rotate together through the rotating sleeve. The moving frame drives the laser head to move up, down, left, and right to perform all-round welding on the rotating silicon steel sheet group. This welding method, which combines the rotation of silicon steel sheets with the movement of the laser head, makes the welding trajectory more flexible and controllable, the weld distribution more uniform, and improves the welding quality and overall strength of the silicon steel sheet core.

[0016] This invention achieves double-stable fixation of multiple sets of stacked silicon steel sheets by setting up a fixing mechanism and using the cooperation of components such as a mounting frame, top ring, fixing plate, inclined groove, slider, top spring, connecting spring, connecting rod, and unlocking ring. Before welding, the operator inserts the multiple sets of silicon steel sheets to be welded, along with the intermediate shaft, into the rotating sleeve. Then, the intermediate shaft is aligned with the rotating tube, and the guide strip is aligned with the guide groove. Next, the lower pressure frame, along with the fixing ring and rotating ring, is inserted, so that the lower end face of the rotating ring is in close contact with the uppermost silicon steel sheet. During the insertion of the lower pressure frame, the slider tends to slide along the inclined groove towards the larger diameter end, thus avoiding obstruction. After the lower pressure frame is inserted, it forms a self-locking mechanism under the action of the top spring. The top spring always provides an upward thrust to the slider, pushing the slider to slide along the inclined groove towards the smaller diameter end, so that the inner wall of the slider is in close contact with the outer wall of the lower pressure frame, thus locking the lower pressure frame. This completes the initial fixation of multiple sets of silicon steel sheets. An air blowing device is connected to the air inlet pipe, and the lower pressure frame is installed... Then, the external air blowing device is activated. Gas enters the four sets of pressure pipes through the air inlet pipe to compress the push rod. The tension spring is stretched, and the push rod slides outward along the pressure pipe until it is inserted into the corresponding inclined pressure rod. The inclined pressure rod continues to slide along the groove and then tightly presses the fixing ring. The pressure is transmitted to the silicon steel sheet through the thrust bearing and the rotating ring, making the multiple sets of silicon steel sheets more stable. This dual fixing method, which combines mechanical self-locking and air pressure, has a more uniform and reliable clamping force distribution compared to the simple pressing and fixing in the existing technology. It effectively solves the problems of uneven clamping force and poor edge clamping effect in the traditional fixing method, which leads to gaps or local loosening of the silicon steel sheet layers. The design of the thrust bearing allows the rotating ring to rotate freely with the silicon steel sheet and the intermediate shaft without affecting the fixing ring above. Under normal conditions, the tension spring always provides tension to the push rod, causing the push rod to retract into the pressure pipe, avoiding affecting the insertion and installation of the silicon steel sheet and the rotating ring and other components. The overall operation process is simple and smooth.

[0017] This invention, through the design of a pressure relief mechanism, employs the coordinated operation of components such as a pressure relief pipe, air outlet, sealing ring, threaded cylinder, bottom rod, ring spring, sliding rod, top plate, compression spring, sealing disc, and adjusting ball. This achieves rapid and safe pressure relief and convenient unlocking and removal after welding. When removing the welded silicon steel sheet assembly and intermediate shaft after welding, the operator first stops the external air blowing device, then manually presses down on the unlocking ring. The unlocking ring, via a pressure plate, drives the connecting rod and connecting spring to move downwards simultaneously, thereby pushing the slider downwards and causing it to slide along the inclined groove towards the larger diameter end, releasing the slider from the lower pressure frame side. The tight contact of the wall and the simultaneous downward movement of the unlocking ring will also press down the top plate and slide rod. The slide rod overcomes the pressure of the compression spring and pushes the sealing plate downward, causing the sealing plate to release the sealing contact with the sealing ring. At this time, the gas in the pressure pipe and connecting pipe is discharged into the pressure relief pipe through the gap between the sealing plate and the sealing ring and finally discharged through the vent. After the pressure in the pressure pipe is released, the tension spring rebounds and pulls the push rod to retract into the pressure pipe to release the contact with the inclined pressure rod. At this time, the lower pressure frame and the rotating pipe below it can be removed, and then the welded silicon steel sheet assembly and intermediate shaft can be removed. The whole unlocking and pressure relief process is simple to operate and easy for the staff to operate. Attached Figure Description

Three sets of adjusting balls 311 of different sizes are connected to the slide rod 37. The diameter of the adjusting balls 311 decreases from top to bottom. The annular spring 36 is used in conjunction with the adjusting balls 311.

[0024] In this invention, the device can simultaneously weld stacked silicon steel sheets 111 on both sides, and the multiple stacked silicon steel sheets 111 can be firmly fixed by a fixing mechanism. Specifically, before welding, the operator needs to insert the multiple sets of silicon steel sheets 111 to be welded, along with the intermediate shaft 110, into the rotating sleeve. Then, the intermediate shaft 110 is aligned with the rotating tube 217, and the guide strip 213 is aligned with the guide groove 26. Then, the lower pressure frame 212, along with the fixing ring 214 and the rotating ring 218, is inserted, so that the lower end face of the rotating ring 218 abuts against the uppermost silicon steel sheet 111. Under normal conditions, the tension spring 224 always provides tension to the push rod 223, causing the push rod 223 to retract into the pressure tube 22. Within 1, to avoid affecting the insertion of components such as silicon steel sheet 111 and swivel ring 218, during the insertion of the lower pressure frame 212, the slider 25 tends to slide along the inclined groove 24 towards the end with the larger diameter of the inclined groove 24, so it will not be obstructed. After the lower pressure frame 212 is inserted, it will form a self-locking mechanism. Under the action of the top spring 27, the top spring 27 will always provide an upward thrust to the slider 25. Therefore, after the lower pressure frame 212 is inserted, the top spring 27 pushes the slider 25 to slide along the inclined groove 24 towards the end with the smaller diameter of the inclined groove 24, so that the inner side wall of the slider 25 is tightly abutted against the outer side wall of the lower pressure frame 212, thereby locking the lower pressure frame 212 and thus achieving the initial fixation of multiple sets of silicon steel sheets 111. In this invention, after the air inlet pipe 222 is connected to an external air blowing device and the lower pressure frame 212 is installed, the external air blowing device needs to be activated. Gas enters the four sets of pressure pipes 221 through the air inlet pipe 222. The sealing disc 310 of the pressure relief mechanism is a one-way sealing disc 310, so the gas can only compress the push rod 223. The tension spring 224 is stretched, and the push rod 223 slides outward along the pressure pipe 221 under pressure until it is inserted into the corresponding inclined pressure rod 216. It continues to push the inclined pressure rod 216 to slide along the slide groove 215, thereby tightly pressing the fixing ring 214. The pressure is transmitted to the silicon steel sheet 1 through the thrust bearing 219 and the rotating ring 218. 11. To make the multiple sets of silicon steel sheets 111 more stable, the motor 15 is started. The motor 15 drives the drive wheel 16 to rotate. The drive wheel 16 will drive the follower wheel 19 meshing with it to rotate synchronously. The follower wheel 19 drives the intermediate shaft 110 and the multiple sets of silicon steel sheets 111 to rotate through the rotating sleeve. The upper end of the intermediate shaft 110 will drive the follower tube 217 and the rotating ring 218 to rotate accordingly. The thrust bearing 219 is designed to avoid the rotation of the rotating ring 218 from affecting the fixed ring 214. The moving frame 12 will drive the laser head 13 to move up, down and left and right, thereby driving the laser head 13 to perform welding work on the rotating silicon steel sheet 111 sets. After welding, the welded silicon steel sheets 111 and intermediate shaft 110 need to be removed. At this point, the external air blowing device must be stopped to release pressure. The operator needs to manually press down on the unlocking ring 210. The unlocking ring 210, through the pressure plate 211, drives the connecting rod 29 and connecting spring 28 to move downwards simultaneously, thus pushing the slider 25 downwards. This causes the slider 25 to slide along the inclined groove 24 towards the larger diameter end of the inclined groove 24, releasing the tight contact between the slider 25 and the side wall of the lower pressure frame 212. Simultaneously, the downward movement of the unlocking ring 210 also presses down on the top plate 38 along with the sliding rod 37. The sliding rod 37 overcomes the pressure spring 39. The pressure pushes the sealing disc 310 downward, causing the sealing disc 310 to release its sealing contact with the sealing ring 33. At this time, the gas in the pressure pipe 221 and the connecting pipe 225 is discharged into the pressure relief pipe 31 through the gap between the sealing disc 310 and the sealing ring 33, and finally discharged through the vent 32. The pressure in the pressure pipe 221 is released, and the tension spring 224 rebounds and pulls the push rod 223 to retract into the pressure pipe 221, causing the push rod 223 to release its contact with the inclined pressure rod 216. At this time, the lower pressure frame 212 and the rotating pipe 217 below it can be removed, and then the welded silicon steel sheet 111 group and the intermediate shaft 110 can be removed. According to actual needs, such as the number of silicon steel sheets 111 to be welded, the operator can adjust the adjusting ball 311 corresponding to the annular spring 36. The operator can rotate the threaded cylinder 34 to drive it to move up and down along the pressure relief pipe 31. For example, moving the threaded cylinder 34 upward will increase the compression of the compression spring 39. The greater the compression of the compression spring 39, the greater the upward thrust provided by the compression spring 39 to the top plate 38, and the more secure the sealing contact between the sealing disc 310 and the sealing ring 33 will be. However, when unlocking, the operator needs to use greater downward pressure. As the threaded cylinder 34 moves upward, it will also drive the annular spring 36 to move upward synchronously through the bottom rod 35. The annular spring 36 can be adjusted. The adjusting ball 311 is positioned to correspond to different locations, so that the annular spring 36 is locked in the center position where the diameter of the corresponding adjusting ball 311 is the largest. When unlocking is required, the slide bar 37 is pressed down, and the adjusting ball 311 that is locked in the annular spring 36 will move down with the slide bar 37. The annular spring 36 will then move relative to the adjusting ball 311, so that the adjusting ball 311 is located below the annular spring 36. At this time, the annular spring 36 provides downward pressure on the adjusting ball 311, thereby neutralizing part of the pressure of the compression spring 39. The design of adjusting balls 311 of different sizes allows the operator to adjust the position of the annular spring 36 according to actual needs, making the subsequent unlocking work easier and increasing the sealing effect.
