Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, and in particular to a machining welding apparatus. Background Technology

[0002] In the field of modern machining and manufacturing, welding technology, as a core technology for connecting and assembling metal components, is widely used in key industries such as engineering machinery, automobile manufacturing, shipbuilding, and aerospace. Its processing quality directly determines the structural strength, safety, and service life of mechanical products.

[0003] Regarding current welding devices, the existing welding machine for machining disclosed in patent number "CN107214447B" can isolate the transmission of the welding flame through the welding table at the top of the conveying device, thus preventing the welding flame from damaging the conveying device. A fixing groove is provided on the inner side of the welding table, which can place the parts to be welded. During this process, the parts can be fixed by a limiting rod to ensure the stability of the parts during welding. The limiting rod can move left and right with the sliding slot, thereby changing the size of the space inside the limiting rod, which is suitable for welding different parts.

[0004] The aforementioned device directly welds the workpiece during welding operations. However, in actual processing, the workpiece surface often has floating oil adhering to it. If this oil is not removed beforehand, it will decompose and generate gas at the high welding temperature, leading to defects such as bubbles and slag inclusions inside the weld, severely weakening the strength and density of the weld and affecting product quality. Therefore, this application proposes a machining welding device. Summary of the Invention

[0075] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0076] Example 1:

[0077] Reference Figures 1 to 8 A machining and welding device includes a base 1, a welding table 2 fixedly connected to the top surface of the base 1, symmetrically provided grooves 21 on the welding table 2, a placement plate 3 slidably connected inside the grooves 21, a support frame 4 fixedly connected to the top surface of the base 1, a through groove 41 provided on the top surface of the support frame 4, a sliding seat 5 slidably connected inside the through groove 41, a mounting base 6 fixedly connected to the top surface of the base 1, a frame 7 fixedly connected to the top surface of the base 1, and a welding device 8 mounted on the frame 7.

[0078] A machining welding device further includes a docking assembly, a driving assembly, a cleaning assembly, and a scraping assembly. The docking assembly is used for docking and welding workpieces. The docking assembly includes a first motor 31, a rotating shaft 32, a double-ended screw 33, a sliding block 34, a cylinder 35, and a clamping plate 36. The first motor 31 is fixedly connected to the side wall of the welding table 2. The rotating shaft 32 is fixedly connected to the first motor 31 and is rotatably connected to the welding table 2. The double-ended screw 33 is fixedly connected to the output end of the rotating shaft 32 away from the first motor 31 and is rotatably connected to the through groove 41. The sliding block 34 is threadedly connected to the double-ended screw 33 and is slidably connected to the through groove 41. The cylinder 35 is fixedly connected to the top surface of the placement plate 3, and the clamping plate 36 is fixedly connected to the output end of the cylinder 35.

[0079] In this embodiment, the workpieces to be welded are placed on two placement plates 3 respectively. The cylinder 35 on the placement plate 3 is activated, and the output end of the cylinder 35 pushes the clamping plate 36 to move towards the workpiece until the clamping plate 36 clamps the workpiece. Then, the first motor 31 is activated, and its output end drives the rotating shaft 32 to rotate. The rotating shaft 32 synchronously drives the double-ended screw 33 to rotate in the through groove 41. Since the sliding block 34 is threadedly connected to the double-ended screw 33 and is limited by the through groove 41, when the double-ended screw 33 rotates, it will drive the two sliding blocks 34 to move towards each other along the through groove 41, thereby driving the placement plate 3 to move synchronously along the slide groove 21 to achieve the alignment of the two workpieces. The driving component drives the sliding seat 5 to move along the through groove 41 of the support frame 4, thereby adjusting the position of the cleaning component to clean the floating oil on the surface of the workpiece. At the same time, the welding equipment 8 on the frame 7 can perform welding operations according to the position of the docked workpieces. After welding is completed, the removal component can remove the welding slag on the surface of the workpiece to ensure the welding quality.

[0080] Example 2:

[0081] Reference Figure 5 - Figure 7 This embodiment further includes the following: a drive assembly for driving the sliding seat 5 to slide horizontally. The drive assembly includes a second motor 42, a rotating shaft 43, a threaded rod 44, a rotating rod 45, a retaining strip 46, a first transmission wheel 47, a second transmission wheel 48, and a drive belt 49. The second motor 42 is fixedly connected to the side wall of the support frame 4. The rotating shaft 43 is fixedly connected to the output end of the second motor 42 and is rotatably connected to the support frame 4. The threaded rod 44 is fixedly connected to the rotating shaft 43 and is rotatably connected to the support frame 4. The threaded rod 44 is threadedly connected to the sliding seat 5. The rotating rod 45 is rotatably connected to the inner side wall of the support frame 4. The sliding seat 5 is slidably connected to the rotating rod 45. The retaining strip 46 is fixedly connected to the rotating rod 45. The first transmission wheel 47 is fixedly connected to the rotating shaft 43. The second transmission wheel 48 is fixedly connected to the rotating rod 45. The drive belt 49 is wound around the first transmission wheel 47 and the second transmission wheel 48 respectively.

[0082] The cleaning assembly is used to remove floating oil from workpieces. The cleaning assembly includes transmission components, reciprocating components, and water pumping components.

[0083] The transmission components include a sleeve 51, a slot 52, a first bevel gear 53, a hollow rod 54, a second bevel gear 55, and a brush disc 516. The sleeve 51 is rotatably connected to the inner wall of the sliding seat 5. The slot 52 is formed inside the sleeve 51. The first bevel gear 53 is fixedly connected to the sleeve 51. The hollow rod 54 is rotatably connected to the sliding seat 5. The second bevel gear 55 is fixedly connected to the hollow rod 54. The first bevel gear 53 and the second bevel gear 55 mesh with each other. The brush disc 516 is fixedly sleeved on the sliding seat 51. On the hollow rod 54, the brush disk 516 is set at an eccentric position. When the hollow rod 54 drives the brush disk 516 to rotate around its own axis, the rotation trajectory of the brush disk 516 will form a larger coverage area. Compared with the coaxial setting, it can more fully contact the area to be cleaned on the surface of the workpiece. Especially for the local depressions, corners and other places on the surface of the workpiece that are prone to residual oil, the eccentrically rotating brush disk 516 can achieve more comprehensive wiping coverage through trajectory offset, avoiding cleaning dead corners.

[0084] The reciprocating component includes a crank 56, a rectangular groove 57, a first spring 58, a cross plate 59, and a support 510. The crank 56 is fixedly connected to the sleeve rod 51. The rectangular groove 57 is opened on the inner side wall of the sliding seat 5. The first spring 58 is fixedly connected to the inner wall of the rectangular groove 57. The cross plate 59 is fixedly connected to the end of the first spring 58 away from the rectangular groove 57. The cross plate 59 is slidably connected to the rectangular groove 57. The support 510 is fixedly connected to the top surface of the sliding seat 5.

[0085] The pumping unit includes a piston rod 511, a sealing tube 512, an outlet pipe 513, an inlet pipe 514, and a storage tank 515. The piston rod 511 is fixedly connected to the end of the horizontal plate 59 away from the first spring 58. The sealing tube 512 is fitted onto the piston rod 511 and is fixedly fitted onto the support 510. The outlet pipe 513 is connected to the sealing tube 512 and communicates with the hollow rod 54. The inlet pipe 514 is connected to the sealing tube 512. The storage tank 515 is fixedly connected to the support 515. The side wall of the sliding seat 5 is connected to the liquid storage pipe and the liquid inlet pipe 514. An adapter is provided at the connection between the liquid outlet pipe 513 and the hollow rod 54. The adapter is made of metal. One end of the adapter is sealed to the liquid outlet pipe 513 by a snap-fit ​​to ensure that the cleaning fluid will not leak from the interface. The other end forms a rotational seal with the outer wall of the hollow rod 54, which can not only fit tightly with the opening of the hollow rod 54 to prevent the cleaning fluid from overflowing, but also will not hinder the hollow rod 54 from rotating synchronously with the second bevel gear 55.

[0086] Both the outlet pipe 513 and the inlet pipe 514 are equipped with one-way valves. The one-way valve in the inlet pipe 514 only allows the cleaning fluid to flow from the storage tank 515 to the sealing pipe 512.

[0087] In this embodiment, when the workpiece on the placement plate 3 slides to the bottom of the support frame 4, the second motor 42 is started, and its output end drives the rotating shaft 43 to rotate, and synchronously drives the threaded rod 44 fixed thereto to rotate. Since the threaded rod 44 is threadedly connected to the sliding seat 5, the rotation of the threaded rod 44 will cause the sliding seat 5 to slide smoothly on the threaded rod 44 along the guide rod 45.

[0088] When the rotating shaft 43 rotates, it also drives the first transmission wheel 47 to rotate. The first transmission wheel 47 drives the second transmission wheel 48 to rotate through the transmission belt 49. The second transmission wheel 48 then drives the rotating rod 45 to rotate. The retaining strip 46 on the rotating rod 45 enhances the friction between the rotating rod 45 and the sliding seat 5, ensuring that the sliding seat 5 remains stable during the sliding process without any shaking.

[0089] When the rotating rod 45 rotates, the sleeve rod 51 inside the sliding seat 5 rotates through the cooperation of the slot 52 and the clip 46. The first bevel gear 53 fixed outside the sleeve rod 51 rotates accordingly. Since the first bevel gear 53 and the second bevel gear 55 mesh with each other, the second bevel gear 55 is driven to rotate. The second bevel gear 55 drives the hollow rod 54 to rotate. The hollow rod 54 drives the brush disk 516 to rotate. The brush disk 516 wipes the surface of the workpiece.

[0090] As the sleeve rod 51 rotates, it drives the crank 56 to rotate. When the protruding part of the crank 56 contacts the horizontal plate 59, it pushes the horizontal plate 59 to slide upward in the rectangular groove 57. When the piston rod 511 slides upward with the horizontal plate 59, the alcohol in the sealing tube 512 enters the hollow rod 54 through the liquid outlet pipe 513 and flows into the bristles of the brush plate 516. Combined with the rotating wiping action of the brush plate 516, it achieves efficient cleaning of floating oil on the surface of the workpiece. When the protruding part of the crank 56 separates from the horizontal plate 59, under the action of the first spring 58, it drives the piston rod 511 to move downward, creating a negative pressure in the sealing tube 512. This draws the alcohol in the storage tank 515 into the sealing tube 512 through the liquid inlet pipe 514 for storage. This process repeats, so that the brush plate 516 always rotates on the surface of the workpiece with attached alcohol. As the sliding seat 5 moves, it drives the brush plate 516 to evenly remove floating oil and impurities from the surface of the workpiece.

[0091] Example 3:

[0092] like Figure 2 - Figure 8 Compared to Embodiments 1 and 2, in this embodiment, the slag removal assembly is used to remove welding slag from the surface of the workpiece after welding. The slag removal assembly includes a support plate 61, a first rack 62, an electric push rod 63, a round rod 64, a transmission gear 65, a second rack 66, a connecting rod 67, a scraper plate 68, a telescopic rod 69, and a second spring 610. The support plate 61 is fixedly connected to the side wall of the placement plate 3. Multiple first racks 62 are provided, and all of them are fixedly connected to the side wall of the support plate 61. The electric push rod 63 is fixedly connected to the side wall of the welding table 2, and the output end of the electric push rod 63 is fixedly connected to the mounting base 6. The round rod 64 is rotatably connected to the mounting base 6. The transmission gear 65 is fixedly connected to the round rod 64 and meshes with the first rack 62. The second rack 66 is slidably connected to the side wall of the mounting base 6. The mounting base 6 has a groove that matches the second rack 66 to limit its movement direction and prevent deviation.

[0093] The second rack 66 meshes with the transmission gear 65. The connecting rod 67 is fixedly connected to the side wall of the second rack 66 and is slidably connected to the mounting base 6. The shovel plate 68 is fixedly connected to the top of the connecting rod 67. The bottom end of the telescopic rod 69 is fixedly connected to the side wall of the connecting rod 67. The telescopic end of the telescopic rod 69 is fixedly connected to the mounting base 6. One end of the second spring 610 is fixedly connected to the inner wall of the mounting base 6, and the other end of the second spring 610 is fixedly connected to the connecting rod 67.

[0094] In this embodiment, after the workpiece welding is completed, the cylinder 35 on one of the placement plates 3 is activated to release the welded workpiece. At this time, the first motor 31 drives the two placement plates 3 to move towards each other. When it is necessary to remove the welding slag remaining on the surface of the welded workpiece, the electric push rod 63 on the side wall of the welding table 2 is activated. The telescopic end of the electric push rod 63 will drive the mounting base 6 fixed thereto to move backward, so that the scraper and transmission gear 65 on the mounting base 6 move backward. As the placement plate 3 moves continuously, the first rack 62 on the support plate 61 gradually meshes with the transmission gear 65. Because the two mesh with each other, the movement of the placement plate 3 will be converted into the rotational power of the transmission gear 65, thereby causing the transmission gear 65 to rotate around the axis of the round rod 64. It engages with the second rack 66 on the other side. Under the action of the transmission gear 65, the second rack 66 moves forward on the mounting base 6. When the second rack 66 slides, it drives the connecting rod 67, which is fixedly connected to its side wall, to move synchronously. This causes the scraper plate 68, which is fixed at the top of the connecting rod 67, to move closer to the welding slag on the workpiece surface. During this process, the telescopic rod 69, which is fixed to the side wall of the connecting rod 67, will move synchronously with the connecting rod 67, providing stable guidance for the connecting rod 67. At the same time, the second spring 610, which is connected between the inner wall of the mounting base 6 and the connecting rod 67, will be stretched as the connecting rod 67 slides. The elastic buffering characteristics of the spring are used to offset the impact force when the scraper plate 68 contacts the workpiece surface, avoiding scratches or damage to the workpiece surface due to hard contact.

[0095] As the placement plate 3 continues to move, when the first rack 62 gradually separates from the transmission gear 65, the transmission gear 65 loses power and stops rotating. At this time, the second spring 610 releases its elastic potential energy instantly, pulling the connecting rod 67 to reset. The second rack 66, which is fixed to the connecting rod 67, also resets synchronously. This cycle repeats, and the scraper plate 68 can continuously and efficiently clean the welding slag at the workpiece welding point.

[0096] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
