Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a welding device with a slag collection structure. Background Technology

[0002] Welding equipment is a core processing device in the industrial metal processing field, used to weld and form workpieces. It is widely used in the production and manufacturing of various metal components. It mainly achieves the connection and forming of workpieces through fusion welding and is a key piece of equipment in the industrial production process. Currently, there are various types of welding equipment on the market. Basic models only have core welding functions, and some improved models come with simple cleaning or grinding accessories. However, the overall design is mostly focused on a single welding process, and there is insufficient optimization in terms of processing function integration, working condition adaptability, power utilization efficiency, and welding residue treatment. As a result, it is difficult to meet the high requirements of modern production for processing efficiency, workpiece quality, and equipment versatility.

[0003] Existing welding equipment has many technical defects in practical applications, which are in obvious contradiction with processing needs and equipment optimization direction: First, most equipment lacks integrated cleaning and grinding structures. The cleaning of impurities and grinding of weld slag after welding must be completed with additional independent equipment, which cannot realize integrated welding, cleaning and grinding operations, resulting in cumbersome process connections and a significant reduction in production efficiency. Second, the few equipment equipped with cleaning and grinding components lack an adaptive height adjustment structure. The height of the components needs to be manually adjusted, which is difficult to operate and difficult to adapt to workpieces of different heights and specifications, thus limiting the applicability of the equipment.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 16 The present invention provides a technical solution: a welding device with a slag collection structure, including a base 11, a transverse slide rail seat 12 and a longitudinal adjustment seat 14 fixedly installed on the top of the base 11, a welding actuator 13 slidably installed on the top of the transverse slide rail seat 12, and a workpiece clamping table 15 fixedly installed on the movable end of the longitudinal adjustment seat 14. The base 11, the transverse slide rail 12, the welding actuator 13, the longitudinal adjustment seat 14, and the workpiece clamping table 15 constitute the basic welding structure of the device. The workpiece is clamped on the top of the workpiece clamping table 15. The welding actuator 13 is horizontally adjusted along the transverse slide rail 12, and the workpiece clamping table 15 is horizontally adjusted along the longitudinal adjustment seat 14 to achieve precise welding of the workpiece.

[0021] Two collection slots 3 are provided on the upper surface of the base 11. The two collection slots 3 are symmetrically distributed on both sides of the longitudinal adjustment seat 14. A collection box 2 is inserted into each of the two collection slots 3 to collect the residue generated during the grinding and cleaning process. The collection box 2 can be inserted and removed for easy centralized treatment of the residue. Two mounting brackets 4 are fixedly installed on the top of the base 11. A crossbeam 51 is fixed between the two mounting brackets 4 by bolts. A movable seat 53 is installed at the bottom of the crossbeam 51 by a height adaptive component 52. The height adaptive component 52 is used to realize the adaptive height adjustment of the movable seat 53 to adapt to workpieces of different heights.

[0022] The top and bottom of the movable seat 53 are slidably mounted with an upper sliding seat 541 and a lower sliding seat 543 via sliding guide rails 530, respectively. A connecting seat 542 is fixedly connected between the upper sliding seat 541 and the lower sliding seat 543, so that the upper sliding seat 541, the connecting seat 542 and the lower sliding seat 543 form an integrated structure that can slide stably along the movable seat 53. The movable seat 53 has a horizontal sliding cavity 531 inside, which provides horizontal sliding space for the connecting seat 542 and ensures sliding stability.

[0023] The bottom of the lower sliding seat 543 is fixedly connected to two limiting members 57. The limiting members 57 can contact the top of the workpiece on the workpiece clamping table 15. Together with the height adaptive component 52, they can push the movable seat 53 upward to achieve height adaptive adjustment. At the same time, the limiting members 57 press against the outside of the part to be welded, which can effectively block the splashing of residue generated during grinding and cleaning. The bottom of the limiting member 57 is provided with an adapter groove 571, and the part to be welded is located inside the adapter groove 571 to avoid the limiting member 57 from blocking the welding and cleaning parts. The bottom of the two limiting members 57 at their far ends is provided with an inclined surface, which facilitates the movement of the limiting members 57 laterally and the upward movement of the movable seat 53 when the workpiece contacts each other, so as to achieve height self-adaptation.

[0024] The interior of the two adapter slots 571 is equipped with two rotating shaft assemblies 7, which respectively install a rotatable cleaning wheel 58 and a grinding wheel 59. Both the cleaning wheel 58 and the grinding wheel 59 are made of flexible materials to ensure the cleaning and grinding effect. Along the feeding direction of the workpiece clamping table 15 on the longitudinal adjustment seat 14, the cleaning wheel 58 is located in front of the grinding wheel 59, realizing the integrated operation of cleaning the welding parts during feeding and grinding the welding parts during discharging. Among them, the cleaning wheel 58 is used to clean impurities in the welding part during the feeding process to ensure welding quality, and the grinding wheel 59 is used to grind the welding slag and protrusions in the welding part during the discharge process to improve the welding flatness of the workpiece. To ensure the grinding effect, the bottom of the grinding wheel 59 is provided with concentric ring grinding parts with different grit numbers.

[0025] A power box 55 is fixedly connected to the top of the upper sliding seat 541, and a drive motor 50 is fixedly installed on the top of the power box 55. The drive motor 50 provides power for the rotation of the cleaning wheel 58 and the grinding wheel 59. The power box 55 is equipped with a power tapping assembly 6, which is used to decompose the single driving force of the drive motor 50 into two independent driving forces, providing power to the cleaning wheel 58 and the grinding wheel 59 respectively. The connecting seat 542 is equipped with a clutch transmission assembly 8, which is used to realize the independent rotation control of the cleaning wheel 58 and the grinding wheel 59, so that the cleaning wheel 58 works when feeding and the grinding wheel 59 works when discharging, avoiding power waste and improving the rationality of operation.

[0026] The movable seat 53 has two sets of four mounting slots 533 on its outer side. The two sets of mounting slots 533 are symmetrically distributed about the horizontal center plane of the movable seat 53. The sliding guide rail 530 is fixedly installed inside the mounting slot 533. The upper sliding seat 541 and the lower sliding seat 543 are respectively installed on the movable end of each set of sliding guide rails 530, which further ensures the stability of the sliding of the upper sliding seat 541 and the lower sliding seat 543 and avoids deviation during the sliding process.

[0027] The height adaptive component 52 includes four guide slides 521, which are fixedly connected to the top of the movable seat 53 and slide through and slidably connected inside the crossbeam 51. A rubber damping pad is provided between the crossbeam 51 and the guide slides 521. Four return springs 522 are fixedly connected between the crossbeam 51 and the movable seat 53. The return springs 522 cooperate with the rubber damping pads to retain the height adaptive function and absorb vibration and prevent the movable seat from moving. The return springs 522 are sleeved on the outside of the guide slides 521 to prevent the return springs 522 from deflecting too much and to ensure the elastic return effect. An upper limit stop plate 524 is fixedly connected to the top of the guide slide 521, and a travel stop ring 523 is fixedly connected to the outside of the guide slide 521. The two work together to limit the sliding stroke of the guide slide 521 on the crossbeam 51 and prevent the movable seat 53 from moving excessively and causing damage to the component. The working principle of the height adaptive component 52 is as follows: When the inclined surface of the limiting member 57 contacts the workpiece, the movable seat 53 maintains a fixed height under the initial elastic force of the return spring 522. The limiting member 57 is slidably connected to the movable seat 53 through the lower sliding seat 543 and moves laterally under the push of the workpiece. When the limiting member 57 moves to the end of its stroke and can no longer move laterally, the pushing force of the workpiece on the inclined surface of the limiting member 57 pushes the limiting member 57 upward, thereby driving the movable seat 53 to move upward and compressing the return spring 522. When the workpiece disengages from the limiting member 57, the movable seat 53 drives the limiting member 57 to reset under the elastic reset force of the return spring 522, restoring the initial position.

[0028] The residue guiding assembly 56 includes a transmission toothed plate 564, which is fixedly connected to the bottom of the lower sliding seat 543. Two diversion guide plates 563 are fixedly connected to the two ends of the transmission toothed plate 564 respectively. The ends of the two diversion guide plates 563 that are far apart are provided with inclined surfaces that guide the flow to both sides, so as to divert the residue to the collection tank 3. The bottom of the movable seat 53 is rotatably connected to the guide rollers 561 through two mounting shafts 562. The opposite ends of the two guide rollers 561 are set as arc segments, and the arc segments are evenly provided with tooth grooves. The outer side of the transmission toothed plate 564 is symmetrically provided with teeth that mesh with the guide rollers 561, so as to realize the synchronous linkage between the transmission toothed plate 564 and the guide rollers 561.

[0029] The working principle of the residue guiding assembly 56 is as follows: During the feeding process, the contact force between the workpiece and the limiting member 57 pushes the limiting member 57 to move along the feeding direction. The limiting member 57 drives the lower sliding seat 543, the connecting seat 542 and the upper sliding seat 541 to slide along the movable seat 53. Since the guide roller 561 is rotatably mounted on the movable seat 53 through the mounting shaft 562, when the lower sliding seat 543 moves, it drives the transmission tooth plate 564 to move synchronously. Through the meshing transmission between the transmission tooth plate 564 and the guide roller 561, the guide roller 561 is driven to rotate. During the rotation of the guide roller 561, it comes into contact with the diversion guide plate 563 at the bottom of the lower sliding seat 543. After the residue is diverted and guided by the inclined surface of the diversion guide plate 563 and the inclined side of the guide roller 561, it flows to the junction of the guide roller 561 and the diversion guide plate 563, and then falls accurately into the collection groove 3 on the base 11, realizing the accurate collection of residue.

[0030] The upper surface of the movable seat 53 has two mounting holes 534. The mounting shaft 562 is rotatably mounted inside the mounting holes 534 to complete the rotational mounting of the guide roller 561 at the bottom of the movable seat 53, ensuring the stability of the rotation of the guide roller 561.

[0031] The power tapping assembly 6 includes a drive gear 61 and two driven gears 62. The drive gear 61 and the two driven gears 62 are rotatably mounted inside the power box 55. The two driven gears 62 are symmetrically distributed at both ends of the drive gear 61 and mesh with the drive gear 61, so that the drive gear 61 drives the two driven gears 62 to rotate synchronously. An input shaft 63 is fixedly connected inside the driven gear 62. The top of the input shaft 63 passes through and is rotatably connected to the top of the power box 55. It is also fixedly connected to the output end of the drive motor 50 through a coupling, so that the drive motor 50 provides power to the driving gear 61. An output shaft 64 is fixedly connected inside the driven gear 62. The bottom of the output shaft 64 passes through the upper sliding seat 541 and extends into the interior of the connecting seat 542. A friction transmission wheel 65 is fixedly connected to one end of the output shaft 64 inside the connecting seat 542. The driven gear 62 drives the friction transmission wheel 65 to rotate through the output shaft 64, thus completing the distribution and transmission of driving force. The working principle of the power tapping assembly 6 is as follows: the drive motor 50 is started, and the drive motor 50 drives the drive gear 61 to rotate through the input shaft 63. The drive gear 61 drives the two driven gears 62 meshing at both ends to rotate synchronously. The two driven gears 62 drive the two friction transmission wheels 65 to rotate through the corresponding output shafts 64, thereby decomposing the single driving force of the drive motor 50 into two independent rotational driving forces, which provide power support for the cleaning wheel 58 and the grinding wheel 59 respectively.

[0032] The rotating shaft assembly 7 includes a rotating spindle 71, which is rotatably mounted inside the limiting member 57. The top of the rotating spindle 71 passes through the lower sliding seat 543 and extends into the interior of the connecting seat 542. A support turntable 72 is fixedly connected to one end of the rotating spindle 71 inside the connecting seat 542. The lower surface of the support turntable 72 is connected to the bottom inner wall of the connecting seat 542 by an annular guide rail to ensure the stability of the rotation of the rotating spindle 71 and prevent deviation during rotation. Mounting discs 73 are fixedly connected to one end of the two rotating spindles 71 that pass through the adapter groove 571. The cleaning wheel 58 and the grinding wheel 59 are respectively fixedly mounted on the bottom of the two mounting discs 73 to achieve synchronous rotation of the cleaning wheel 58, the grinding wheel 59 and the rotating spindle 71.

[0033] The clutch transmission assembly 8 includes a fixed plate 81, which is fixedly connected to the inside of the movable seat 53. Two sets of four push-in blocks 86 are fixedly connected to both ends of the fixed plate 81. The end of the push-in block 86 away from the fixed plate 81 is set as an inclined part. Inside the connecting seat 542, two lifting sleeves 82 are slidably connected via guide blocks 85. Inside the lifting sleeves 82, a transmission disc 83 is rotatably mounted via bearings. A splined shaft 84 is fixedly connected to the bottom of the transmission disc 83. The splined shaft 84 is slidably connected to the inside of the rotating main shaft 71 via splines. When the transmission disc 83 drives the splined shaft 84 to move up and down, the splined shaft 84 can maintain a sliding connection with the rotating main shaft 71. When the splined shaft 84 rotates, it can drive the rotating main shaft 71 to rotate synchronously via splines. The lower surface of the lifting slide sleeve 82 has two inclined push grooves 803. The inclined push grooves 803 correspond to the positions of the push block 86. The inner wall of the end of the inclined push groove 803 opposite to the push block 86 is set as an inclined surface that is adapted to the inclined part of the push block 86. Through the cooperation of the inclined surface and the inclined part, the push block 86 pushes the lifting slide sleeve 82 to move upward. The working principle of the clutch transmission assembly 8 is as follows: During the workpiece feeding process, the workpiece pushes the limiting part 57 to drive the lower sliding seat 543 to move laterally, the lower sliding seat 543 drives the connecting seat 542 to move laterally along the horizontal sliding cavity 531 inside the movable seat 53, and the connecting seat 542 drives the two lifting sliding sleeves 82 inside to move synchronously. Since the fixed plate 81 and the push-up inclined block 86 are fixed inside the movable seat 53, the inclined push groove 803 at the bottom of the lifting sleeve 82 near the cleaning wheel 58 will contact the corresponding push-up inclined block 86. Under the cooperation of the inclined part of the push-up inclined block 86 and the inclined surface of the inclined push groove 803, the push-up inclined block 86 pushes the lifting sleeve 82 to move upward. The lifting sleeve 82 drives the internal transmission disc 83 to move upward synchronously through the bearing, so that the transmission disc 83 and the friction transmission wheel 65 corresponding to the power tapping assembly 6 are tightly fitted, and friction is used to achieve Kinetic energy is transmitted, and the friction drive wheel 65 drives the drive disc 83 to rotate. The drive disc 83 drives the rotating main shaft 71 to rotate through the spline shaft 84. The rotating main shaft 71 drives the cleaning wheel 58 to rotate through the mounting disc 73, thereby realizing the cleaning operation of the welded part of the workpiece. Similarly, during the workpiece unloading process, the lifting sleeve 82 near the end of the grinding wheel 59 will move upward under the action of the corresponding push inclined block 86, so that the corresponding drive disc 83 is in contact with the friction drive wheel 65, driving the grinding wheel 59 to rotate, thereby realizing the grinding operation of the welded part of the workpiece.

[0034] Two fixed grooves 532 are symmetrically opened on the inner wall of the horizontal sliding cavity 531. A through groove 802 is symmetrically opened on the outer side of the connecting seat 542. The two ends of the fixed plate 81 pass through the two through grooves 802 respectively and are fixedly installed inside the two fixed grooves 532. When the connecting seat 542 moves horizontally, the fixed plate 81 and the push-up inclined block 86 remain fixed, ensuring that the push-up inclined block 86 can stably push the lifting sliding sleeve 82 to move up and down, so as to realize the alternating work of the cleaning wheel 58 and the grinding wheel 59.

[0035] The connecting seat 542 is symmetrically provided with inclined block grooves 801 on the outer side along the feeding and discharging direction. The push-up inclined block 86 is slidably connected to the inner side of the inclined block groove 801. After the push-up inclined block 86 supports the bottom of the lifting sleeve 82, the push-up inclined block 86 slides into the inclined block groove 801 to support the end of the push-up inclined block 86 away from the fixed plate 81, ensuring the stability of the lifting sleeve 82 and the friction transmission wheel 65, and avoiding slippage during transmission.

[0036] The guide blocks 85 are set in two groups of four, with two guide blocks 85 in each group symmetrically and fixedly connected to the bottom of the lifting sleeve 82; A guide groove 804 is provided on the side of each pair of guide blocks 85 that are far apart. A limit strip 87 is fixedly connected to the inner wall of the connecting seat 542. The limit strip 87 is slidably connected inside the guide groove 804 to limit and guide, ensuring that the guide block 85 can drive the lifting slide sleeve 82 to slide stably up and down along the inner wall of the connecting seat 542, and preventing the lifting slide sleeve 82 from deviating.

[0037] The working process of this embodiment: Workpiece installation and equipment debugging: Clamp the workpiece to be welded on the top of the workpiece clamping table 15. Anti-slip rubber pads can be set as needed to ensure the stability of workpiece clamping; start the drive motor 50, which drives the two friction transmission wheels 65 to rotate through the power tapping assembly 6 to complete the equipment debugging.

[0038] Feeding and cleaning: The longitudinal adjustment seat 14 drives the workpiece clamping table 15 to move along the feeding direction. The workpiece contacts the inclined surface at the bottom of the limiting member 57, pushing the limiting member 57 to move laterally. The limiting member 57 drives the lower sliding seat 543, the connecting seat 542 and the upper sliding seat 541 to slide along the sliding guide rail 530 of the movable seat 53. At this time, the inclined push groove 803 at the bottom of the lifting sleeve 82 near the cleaning wheel 58 contacts the corresponding push block 86. The push block 86 pushes the lifting sleeve 82 upward, so that the transmission disc 83 is in contact with the corresponding friction transmission wheel 65. The transmission disc 83 is driven to rotate by friction. The transmission disc 83 drives the rotating main shaft 71 to rotate through the spline shaft 84. The rotating main shaft 71 drives the cleaning wheel 58 to rotate, and cleans the impurities at the welded part of the workpiece. At the same time, the lower sliding seat 543 drives the transmission toothed plate 564 to move. The transmission toothed plate 564 drives the guide roller 561 to rotate through gear meshing. The residue generated during cleaning is diverted by the inclined surface of the diversion guide plate 563 and guided by the side of the guide roller 561, and falls precisely into the collection box 2 in the collection trough 3.

[0039] Welding operation: After cleaning, the workpiece continues to move to the bottom of the welding actuator 13. The horizontal position of the welding actuator 13 is adjusted by the horizontal slide rail seat 12, and the vertical position of the workpiece clamping table 15 is adjusted by the vertical adjustment seat 14, so that the welding actuator 13 is aligned with the part to be welded. The welding actuator 13 is started to complete the welding operation of the workpiece.

[0040] Discharge and Grinding: After welding is completed, the longitudinal adjustment seat 14 drives the workpiece clamping table 15 to continue moving along the discharge direction. The workpiece pushes the limiting part 57 to move laterally in the opposite direction, which drives the connecting seat 542 to slide in the opposite direction. At this time, the lifting sleeve 82 near the grinding wheel 59 moves upward under the action of the corresponding push inclined block 86, so that the corresponding transmission plate 83 is in contact with the friction transmission wheel 65, which drives the grinding wheel 59 to rotate and grind the welding slag and protrusions of the workpiece welding part. During the grinding process, the limiting part 57 presses on the surface of the workpiece to block the splash of the residue generated by grinding, so that it is guided by the residue guiding component 56 and falls into the collection box 2 on the other side.

[0041] Residue cleaning and equipment reset: After the operation is completed, turn off the drive motor 50 and the welding actuator 13, and remove the welded workpiece; pull the collection box 2 out of the collection tank 3, clean the residue in the collection box 2, and insert the collection box 2 back into the collection tank 3 after cleaning; under the elastic reset force of the reset spring 522, the movable seat 53 drives the limit part 57, cleaning wheel 58, grinding wheel 59 and other components to reset, waiting for the next operation.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
