Description

Technical Field

[0001] The present invention relates to the field of welding fixtures, and more particularly to a welding fixture for mechanical manufacturing. Background Art

[0002] Welding fixtures, also known as welding fixtures for short, are process equipment used to clamp and fix cylindrical workpieces during welding to keep them in the correct position. According to their structural characteristics and uses, welding fixtures can be divided into many types, such as general fixtures, special fixtures, combination fixtures, adjustable fixtures and flexible fixtures. Among them, general fixtures such as chucks and vises have wide applicability; special fixtures are designed for specific cylindrical workpieces and have higher precision and efficiency; combination fixtures are composed of standard parts and have greater flexibility and adaptability; adjustable fixtures change the size and shape of the fixture by adjusting the mechanism to adapt to the welding requirements of different cylindrical workpieces; flexible fixtures adopt a modular design, which can quickly adjust the layout and positioning of the fixture to meet the welding requirements of complex cylindrical workpieces.

[0003] Welding slag is formed because the welding rod or wire used in welding contains a certain amount of impurities and flux, which will form non-metallic oxides, silicates and other substances after heating. In addition, the surfaces of the welded parts are close together, and the space in the welding area is small. Some gases and volatile substances cannot escape in time and will be trapped in the welding area. After cooling and solidification, welding slag is formed. The presence of welding slag will affect the appearance and quality of the weld, and may even cause cracks and defects, thereby affecting the strength and sealing of the weld.

[0004] In the prior art, impurities and oxides contained in the core of the welding rod are melted to produce welding slag during the welding process. The welding slag mainly adheres to the surface of the weld, and its presence affects the strength and sealing of the weld. However, the welding slag is usually knocked off after the welding is completed, which increases the time required for welding a single batch of cylindrical workpieces, thereby affecting the welding efficiency of subsequent cylindrical workpieces.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention knocks the welding part of the cylindrical workpiece by setting a striker that moves up and down repeatedly to knock off the welding slag. Since the first rotating drum drives the cylindrical workpiece to rotate counterclockwise, the welded position of the cylindrical workpiece will turn to the inside of the welding chamber, and the striker will start to accumulate force when it is lifted up and quickly hit the welding part of the cylindrical workpiece when it descends, so as to quickly knock off the welding slag after the welding is completed, thereby saving the time required to complete all welding of a single batch of cylindrical workpieces.

[0020] (2) The impact plate provided in the present invention will impact the cylindrical workpiece again after the impact rod impacts the cylindrical workpiece, so as to achieve the purpose of reducing the stress at the welding point of the cylindrical workpiece. Since the cylindrical workpiece will generate stress due to thermal expansion and welding deformation limitation during the welding process, and the position where the two impact plates impact is close to the welding point, the timing of the impact is after the welding is completed, which provides time for the cooling of the welding point. This not only reduces the stress at the welding point of the cylindrical workpiece after welding, but also saves the time required to complete all welding of a single batch of cylindrical workpieces.

[0021] (3) The collecting box of the present invention is repeatedly moved up and down by the push of the second connecting plate, so that the welding slag collected in the collecting box is repeatedly shaken. As the impact rod strikes the welding slag, the cylindrical workpiece will also slowly rotate along with the first rotating drum. The welding slag that was originally knocked off and remained on the outside of the cylindrical workpiece gradually falls into the collecting box after the cylindrical workpiece rotates clockwise, thereby avoiding the welding slag remaining on the surface of the cylindrical workpiece from being hit by the impact rod again and causing wear on the surface of the cylindrical workpiece. At the same time, due to the frequent up and down shaking of the collecting box, the welding slag collected by the collecting box becomes more compact after the frequent shaking, thereby increasing the amount of welding slag collected by the collecting box.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 A welding fixture for mechanical manufacturing includes a base 1 and a fixing seat 2 fixedly connected to the middle part of the upper side of the base 1, and the number of the fixing seats 2 is two. A welding chamber 21 is fixedly connected to the upper side of the base 1, and the welding chamber 21 is located between the two fixing seats 2. A dual-axis motor 3 is fixedly installed inside the base 1, and a slag removal component 4 is provided inside and on the upper side of the base 1.

[0034] The slag removal component 4 includes a gear 41 fixedly connected to the output ends of both sides of the dual-axis motor 3, and the interior of the two fixed seats 2 are rotatably connected to the first rotating drum 42, and the outer middle parts of the two first rotating drums 42 are fixedly connected to the annular racks 43, and the outer sides of the two gears 41 are respectively meshed with the outer sides of the two annular racks 43. The outer sides of the two first rotating drums 42 are respectively fixedly connected to the outer sides of the two annular racks 43. The sides close to the outer sides of the two first rotating drums 42 are fixedly connected to the pushing blocks 44 in an annular array, and the multiple pushing blocks 44 are all provided with inclined surfaces when rotating counterclockwise. The upper side of the welding chamber 21 is slidably connected to the impact rod 46, and the left and right sides of the lower end of the impact rod 46 are fixedly connected to the lifting seat 45. The lifting seat 45 is provided with an inclined surface in the clockwise rotation direction of the gear 41. After the multiple pushing blocks 44 rotate, they slide and lift with the lifting seat 45, and the lower side of the impact rod 46 is fixedly connected to the first tension spring 47, and there are two first tension springs 47, and the other ends of the two first tension springs 47 are jointly fixedly connected to the upper side of the welding chamber 21.

[0035] A clamping component 5 is provided on the upper side of the base 1 .

[0036] By adopting the above technical solution, first, two cylindrical workpieces to be welded are respectively inserted into the two first rotating drums 42, and then the two cylindrical workpieces are pushed toward each other so that the end to be welded is inserted into the welding chamber 21 and docked, and then the cylindrical workpieces are welded from the opening at the front end of the welding chamber 21 through the external welding equipment, and then the dual-axis motor 3 is started to drive the two gears 41 to rotate slowly clockwise. Because the two first rotating drums 42 will respectively rotate in a circle inside the two fixed seats 2, and the annular rack 43 on the outside of the first rotating drum 42 is engaged with the gear 41, so that when the gear 41 rotates clockwise, the clamping component 5 will restrict the workpiece inside the first rotating drum 42, so that the cylindrical workpiece will rotate counterclockwise with the first rotating drum 42. During the rotation of the first rotating drum 42, the multiple pushing blocks 44 on its outside will also rotate with it. After the pushing block 44 rotates, the inclined surface of the rotating block will contact the inclined surface of the lifting seat 45, so that the lifting seat 45 drives the striker on the lower side to slowly lift. As the rotating seat continues to rotate, when the upper side of the pushing block 44 contacts the lower side of the lifting seat 45, the lifting seat 45 and the striker 46 will reach the highest point of the rise, and after the pushing block 44 is separated from the lifting seat 45, the lifting seat 45 loses the support from the pushing block 44, and the two first tension springs 47 on the upper side of the welding chamber 21 always pull the lifting seat 45. At this time, the tension generated by the first tension spring 47 will quickly drive the lifting seat 45 and the striker 46 to reset, and the quickly reset striker 46 will hit the two The welding part of the cylindrical workpiece is caused to hit the welding slag at the welding part by the striker 46. The above steps can be repeated to repeatedly strike the cylindrical workpiece. Since the first rotating drum 42 drives the cylindrical workpiece to rotate counterclockwise, the welded position of the cylindrical workpiece will turn to the inside of the welding chamber 21, and the striker 46 will begin to accumulate force when it is lifted and quickly hit the welding part of the cylindrical workpiece when it descends, so as to quickly knock out the welding slag after the welding is completed, thereby saving the time required to complete all welding of a single batch of cylindrical workpieces.

[0037] like Figures 1 to 3 and Figure 5 and Figure 6 As shown, there are two lifting seats 45, and the lifting seats 45 are provided with an inclined surface in the clockwise rotation direction toward the gear 41. There are two first tension springs 47, and the other ends of the two first tension springs 47 are fixedly connected to the upper side of the welding chamber 21. The plurality of pushing blocks (44) are provided with inclined surfaces in the direction when rotating counterclockwise. The interior of the welding chamber 21 is provided with an impact assembly 48, and the impact assembly 48 includes a movable groove 481 opened inside the welding chamber 21.

[0038] The outer side of the striker 46 is fixedly connected to a first connecting plate 482, and the number of the first connecting plates 482 is two. The two first connecting plates 482 are slidably connected together in the movable groove 481. The inner upper side of the movable groove 481 is fixedly connected to a rubber band 483, and the number of the rubber bands 483 is two. The bottom ends of the two rubber bands 483 are fixedly connected to a strike plate 484. The two first connecting plates 482 are respectively slidably connected to the outer sides of the two rubber bands 483. The bottom end of the striker 46 is flush with the lower side of the strike plate 484.

[0039] By adopting the above technical solution, first, when the striker 46 moves downward rapidly, the two first connecting plates 482 on its outer side will also move downward rapidly in the movable groove 481. When the two first connecting plates 482 respectively contact the upper sides of the two striker plates 484, the first connecting plates 482 will also drive the striker plates 484 to move downward, and at the same time, the striker plates 484 pull the rubber band 483.

[0040] It should be noted that, because the lower side of the first connecting plate 482 is not flush with the bottom end of the striker 46, when the striker 46 strikes the welding part of the cylindrical workpiece, the first connecting plate 482 quickly strikes the striker plate 484. At this time, the striker plate 484 moves downward quickly with the help of the elasticity of the rubber band 483 and the inertia generated by the strike of the first connecting plate 482, and finally strikes on both sides of the welding part of the cylindrical workpiece. Since the cylindrical workpiece will generate stress due to thermal expansion and welding deformation limitation during the welding process, and the position where the two striker plates 484 strike is close to the welding part, the timing of the strike is after the welding is completed, which provides time for the cooling of the welding part, which not only reduces the stress at the welding part after the cylindrical workpiece is welded, but also saves the time required to complete all welding of a single batch of cylindrical workpieces.

[0041] like Figure 5 and Figure 6 As shown, a shaking assembly 49 is provided inside the welding chamber 21 . The shaking assembly 49 includes a moving groove 491 opened inside the welding chamber 21 , and the moving groove 491 is located at the back of the movable groove 481 .

[0042] The back of the striker 46 is fixedly connected to a second connecting plate 492, which is slidably connected in the movable groove 491. The second connecting plate 492 is in an inverted "L" shape. The inner lower side of the welding chamber 21 is slidably connected to a collecting box 493, and the lower side of the collecting box 493 is fixedly connected to a pressure spring 494, and there are two pressure springs 494. The other ends of the two pressure springs 494 are jointly fixedly connected to the inner lower side of the movable groove 481. The back of the collecting box 493 is fixedly connected to a fixed plate 495, and the lower side of the second connecting plate 492 is in squeeze contact with the upper side of the fixed plate 495.

[0043] By adopting the above technical solution, first, during the downward movement of the striker 46, the striker 46 will drive the second connecting plate 492 to move back and forth up and down in the moving groove 491. When the second connecting plate 492 moves downward and contacts the upper side of the fixed plate 495, the second connecting plate 492 that continues to move downward will push the fixed plate 495 downward, and the fixed plate 495 is fixed to the collection box 493 inside the welding chamber 21, so that the fixed plate 495 drives the collection box 493 to move downward synchronously. At this time, the collection box will squeeze the pressure spring 494 below it. After the second connecting plate 492 moves upward, the fixed plate 495 loses the squeeze from the second connecting plate 492. At this time, the pressure spring 494 will push the collection box 493 upward according to its own elastic force, causing the collection box 493 to shake up and down. As the impact rod 46 strikes the welding slag, the cylindrical workpiece will also slowly rotate with the first rotating drum 42. The welding slag that was originally knocked off and remained on the outside of the cylindrical workpiece will gradually fall into the collection box 493 after the cylindrical workpiece rotates clockwise, avoiding the welding slag remaining on the surface of the cylindrical workpiece from being hit by the impact rod 46 again and causing wear on the surface of the cylindrical workpiece. At the same time, due to the frequent up and down shaking of the collection box 493, the welding slag collected by the collection box 493 becomes more compact after the frequent shaking, thereby increasing the collection capacity of the welding slag by the collection box 493.

[0044] like Figure 6 As shown, the clamping component 5 includes limiting grooves 51 opened inside the two first rotating drums 42 , and the number of limiting grooves 51 inside a single first rotating drum 42 is multiple.

[0045] The interiors of multiple limit grooves 51 are all slidably connected to limit rods 52, and the corresponding ends of the two limit rods 52 close to the openings of the limit grooves 51 are commonly fixedly connected with a snap ring 54, and the opposite sides of the corresponding two snap rings 54 are fixedly installed with rubber pads 55. The outer sides of multiple limit rods 52 are all sleeved with second tension springs 53, and the side of the second tension spring 53 close to the snap ring 54 is fixedly connected to the side of the limit groove 51 close to the snap ring 54, and the side of the second tension spring 53 away from the snap ring 54 is fixedly connected to the outer side of the limit rod 52.

[0046] By adopting the above technical solution, first, when the cylindrical workpiece is inserted into the first rotating drum 42, the second tension spring 53 in the limiting groove 51 will always pull the limiting rod 52, so that the two clamping rings 54 fixed with multiple limiting rods 52 always maintain a tendency to move closer to each other. When the cylindrical workpiece is inserted into the first rotating drum 42, the cylindrical workpiece needs to be inserted between the two clamping rings 54. If the diameter of the cylindrical workpiece is larger than the gap between the clamping rings 54, the two clamping rings 54 will clamp it through the rubber pad 55. At the same time, the limiting rod 52 will also move in the limiting groove 51 until it is adjusted to a state matching the cylindrical workpiece. It should be noted that since the rubber pad 55 is a structure with a relatively soft material, it can not only increase the friction between the clamping ring 54 and the cylindrical workpiece, but also prevent the clamping ring 54 from causing the cylindrical workpiece to deform due to excessive extrusion force. At the same time, the first rotating drum 42 will also drive the cylindrical workpiece to rotate during the rotation process, so as to facilitate rapid welding of the cylindrical workpiece.

[0047] like Figure 7 As shown, material guide components 56 are provided on both sides of the upper end of the base 1. The material guide components 56 include material guide seats 561 fixedly connected to both sides of the upper end of the base 1, and the number of material guide seats 561 is two. The two material guide components 56 are internally rotatably connected to the second rotating drum 562, and the opposite surfaces of the two second rotating drums 562 are fixedly connected to rubber strips 563, and the number of rubber strips 563 is multiple.

[0048] By adopting the above technical solution, before inserting the cylindrical workpiece into the first rotating drum 42, the cylindrical workpiece needs to be inserted into the material guide seat 561 and pass through the second rotating drum 562. Because the second rotating drum 562 is close to the welding chamber 21 and is provided with a plurality of movable rubber strips 563, and the plurality of rubber strips 563 are gathered toward the direction of the welding chamber 21, the cylindrical workpiece can be smoothly inserted. When the cylindrical workpiece passes through the second rotating drum 562, the plurality of rubber strips 563 will be stretched open. When the cylindrical workpiece is pulled out, the rubber strips 563 are in close contact with the outer surface of the cylindrical workpiece, and the friction between the two is increased, so that When the cylindrical workpiece is extracted, the rubber strip 563 will also be pulled by the cylindrical workpiece, making it difficult to extract the cylindrical workpiece. When the cylindrical workpiece is inserted into the second rotating drum 562, the rubber strip 563 is stretched by the cylindrical workpiece, allowing the cylindrical workpiece to move smoothly. When the cylindrical workpiece is pulled in the opposite direction, the cylindrical workpiece is affected by the friction between the rubber strip 563 and it, making it difficult to remove. This ensures the stability of the cylindrical workpiece during the welding process, not only reducing the pressure on the cylindrical workpiece during positioning, but also preventing the surface of the cylindrical workpiece from being deformed due to excessive pressure.

[0049] like Figure 8As shown, a clamping assembly 57 is provided inside the material guide seat 561 , and the clamping assembly 57 includes a third rotating drum 571 rotatably connected to the inner sides of the two material guide seats 561 away from each other.

[0050] A guide groove 572 is provided inside the material guide seat 561, and the outer side of the third rotating cylinder 571 is slidably connected to the guide groove 572. An anti-slip groove 573 is provided inside the third rotating cylinder 571, and a positioning groove 574 is provided on the side of the third rotating cylinder 571 close to the second rotating cylinder 562, and there are multiple positioning grooves 574. A positioning rod 575 is fixedly connected to the side of the second rotating cylinder 562 close to the third rotating cylinder 571, and there are multiple positioning rings. Multiple positioning rods 575 are respectively inserted into multiple positioning grooves 574, and the outer sides of multiple positioning rods 575 are all sleeved with third tension springs 576. The left and right ends of the third tension spring 576 are respectively fixedly connected to the second rotating cylinder 562 and the third rotating cylinder 571.

[0051] By adopting the above technical solution, first, after the cylindrical workpiece is inserted into the guide seat 561, the cylindrical workpiece will also pass through the third rotating cylinder 571, and the third rotating cylinder 571 is provided with an anti-slip groove 573. After the two cylindrical workpieces are docked, the second rotating cylinder 562 pulls the third rotating cylinder 571 through the third tension spring 576, so that the third rotating cylinder 571 slides in the guide groove 572 inside the guide seat 561. In the process of the second rotating cylinder 562 and the third rotating cylinder 571 approaching, the third rotating cylinder 571 slides on the outside of the positioning rod 575 through the positioning groove 574 on its side. Since the third rotating cylinder 571 is provided with an anti-slip groove 573, there is a gripping force between the third rotating cylinder 571 and the cylindrical workpiece. When the third rotating cylinder 571 moves toward the third rotating cylinder 571, it will also drive the cylindrical workpiece to move, so that the two cylindrical workpieces are more closely fitted, so as to prevent the two cylindrical workpieces from being offset during rotation and affecting the welding effect.

[0052] Working principle: First, the cylindrical workpiece will enter the guide seat 561 before being inserted into the first rotating drum 42, and the cylindrical workpiece will first pass through the third rotating drum 571, and the third rotating drum 571 is provided with an anti-slip groove 573, and the second rotating drum 562 pulls the third rotating drum 571 through the third tension spring 576, so that the third rotating drum 571 slides in the guide groove 572 inside the guide seat 561. In the process of the second rotating drum 562 and the third rotating drum 571 approaching, the third rotating drum 571 slides on the outside of the positioning rod 575 through the positioning groove 574 on its side and passes through the second rotating drum 562. Because the second rotating drum 562 is close to the welding chamber 21, a plurality of movable rubber strips 563 are provided. When the cylindrical workpiece passes through the second rotating drum 562, the plurality of rubber strips 563 will be stretched open, and the cylindrical workpiece will be pulled out. When the cylindrical workpiece is being pulled out, the rubber strip 563 is in close contact with the outer surface of the cylindrical workpiece, and the friction between the two increases. As a result, when the cylindrical workpiece is being pulled out, the rubber strip 563 will also be pulled by the cylindrical workpiece, making it difficult to pull out the cylindrical workpiece. After the two cylindrical workpieces are respectively inserted into the two first rotating drums 42, the second tension spring 53 in the limiting groove 51 will always pull the limiting rod 52, so that the two clamping rings 54 fixed with the multiple limiting rods 52 always keep a tendency to move closer to each other. At this time, the cylindrical workpiece needs to be inserted between the two clamping rings 54. If the diameter of the cylindrical workpiece is larger than the gap between the clamping rings 54, the two clamping rings 54 will clamp it through the rubber pad 55. At the same time, the limiting rod 52 will also move in the limiting groove 51 until it is adjusted to a state matching the cylindrical workpiece.

[0053] Then, the two cylindrical workpieces to be welded are inserted into the welding chamber 21 and docked, and then the cylindrical workpieces are welded by external welding equipment. Then, the dual-axis motor 3 is started and the two gears 41 are driven to rotate slowly clockwise. Because the two first rotating drums 42 will rotate in a circle inside the two fixed seats 2 respectively, and the annular rack 43 outside the first rotating drum 42 is engaged with the gear 41, when the gear 41 rotates clockwise, the cylindrical workpiece inside the first rotating drum 42 will rotate counterclockwise with the first rotating drum 42. At this time, the multiple push blocks 44 outside the first rotating drum 42 will also rotate counterclockwise. As it rotates, the inclined surface of the pushing block 44 contacts the inclined surface of the lifting seat 45, causing the lifting seat 45 to drive the striker on its lower side to slowly rise. After the pushing block 44 is separated from the lifting seat 45, the lifting seat 45 loses the support from the pushing block 44, and the two first tension springs 47 on the upper side of the welding chamber 21 always pull the lifting seat 45. At this time, the tension generated by the first tension spring 47 will quickly drive the lifting seat 45 and the striker 46 to reset, and the quickly reset striker 46 will hit the welding point of the two cylindrical workpieces, causing the striker 46 to hit the welding slag at the welding point, and repeat. The above steps can be used to repeatedly strike the cylindrical workpiece. When the striker 46 moves downward rapidly, the two first connecting plates 482 on its outer side will also move downward rapidly in the movable groove 481. When the two first connecting plates 482 are in contact with the upper sides of the two striking plates 484 respectively, the first connecting plates 482 will also drive the striking plates 484 to move downward. At the same time, the striking plates 484 pull the rubber band 483. When the striker 46 hits the welding part of the cylindrical workpiece, the first connecting plate 482 will quickly hit the striking plate 484. At this time, the striking plate 484 uses the rubber band 483 to 3 and the inertia generated when the first connecting plate 482 hits it, it moves downward quickly, and finally hits both sides of the welding part of the cylindrical workpiece. At the same time, the striker 46 will drive the second connecting plate 492 to move up and down reciprocatingly in the moving groove 491, and push the collection box 493 downward when it contacts the upper side of the fixed plate 495. After the second connecting plate 492 moves upward, the fixed plate 495 loses the squeeze from the second connecting plate 492. At this time, the pressure spring 494 will push the collection box 493 upward according to its own elastic force, causing the collection box 493 to shake up and down.
