DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0035] In one embodiment, reference Figure 1-Figure 9 A track-type multi-axis welding robot comprises a track for fixing with a pipe to be welded, a welding actuator on the track for welding the pipe to be welded, the welding actuator can move along the track, the welding actuator comprises a welding gun body 1, and also comprises: a connecting plate 2, fixed on the surface of the welding gun body 1, and a slide groove is provided on the side wall of the connecting plate 2; a vibration mechanism 3, sliding inside the slide groove provided in the connecting plate 2, for vibrating and knocking the internal welding slag of the welding gun body 1; a processing mechanism 4, fixed on one side of the vibration mechanism 3, for adsorbing the welding slag dropped from the welding gun body 1; a rotating mechanism 5, fixed on the top of the welding gun body 1, for circular motion of the vibration mechanism 3.

[0036] With such a scheme, the track of the corresponding welding robot is selected according to the pipeline specifications through the track, and is reliably and accurately installed on the corresponding position of the welded pipeline. Then, the welding actuator is installed on the track. The track can drive the welding actuator to perform multi-axis movement. When the welding actuator performs multi-axis movement, the welding gun body 1 is synchronously driven to work, so as to weld the surface of the pipeline workpiece.

[0037] When the welding gun body 1 is not working, it is fixed to the surface of the welding gun body 1 through the connecting plate 2, so that it can connect the vibration mechanism 3 and the processing mechanism 4, and then it can be installed on the surface of the welding gun body 1 again through the rotating mechanism 5, and the vibration mechanism 3 can be connected again through the rotating mechanism 5 to ensure the stability of the vibration mechanism 3. Since the processing mechanism 4 is located on one side of the vibration mechanism 3, when the vibration mechanism 3 knocks and vibrates the surface of the welding gun body 1, the welding slag can be adsorbed and processed in time. The vibration mechanism 3 can be moved in a circle along the surface of the welding gun body 1 through the rotating mechanism 5, so that the surface of the welding gun body 1 can be better knocked and vibrated evenly to prevent the problem that the welding slag inside the welding gun body 1 is not easy to fall due to different positions.

[0038] In one embodiment, reference Figure 2 , Figure 7 ,and Figure 8 The vibration mechanism 3 includes a bearing frame 31 sliding inside the slide groove, the interior of the bearing frame 31 is rotatably connected to a drive shaft 32 through a bearing, a drive assembly 33 is arranged on the surface of the drive shaft 32, the bottom of the drive shaft 32 is fixedly connected to a limit housing 34, a reciprocating knocking assembly 35 is arranged inside the limit housing 34, and the reciprocating knocking assembly 35 is connected to one end of the drive shaft 32, the drive assembly 33 includes a drive housing 331 fixed to the side wall of the sliding rod 56, and the interior of the drive housing 331 is fixedly connected to a drive gear 3 through a driving part 32, the surface of the driving gear 332 is meshedly connected with the driven gear 333, and the driven gear 333 is fixed on the surface of the driving shaft 32. The reciprocating knocking assembly 35 includes a sliding block 351 sliding inside the limiting shell 34, and the two ends of the sliding block 351 are respectively fixedly connected with a vibration head 352 and a cross plate 353, and a cam 354 is attached to the surface of the cross plate 353, and the cam 354 is fixed on the end of the driving shaft 32. The side wall of the cross plate 353 is fixedly connected with a return spring 355, and the return spring 355 is fixed inside the limiting shell 34.

[0039] By adopting such a scheme, the vibration mechanism 3 can be driven to knock and vibrate the surface of the welding gun body 1 when the welding gun body 1 is not working, so that the welding slag inside the welding gun body 1 can be vibrated and dropped by the vibration force, thereby preventing the welding slag from accumulating inside the welding gun body 1 and affecting the subsequent welding quality.

[0040] During specific operation, the bearing frame 31 is used to connect and support the drive shaft 32, and then the top drive assembly 33 of the drive shaft 32 is driven to rotate the drive shaft 32, and the reciprocating knocking assembly 35 inside the limit shell 34 can be rotated when the drive shaft 32 rotates. When the reciprocating knocking assembly 35 works, the surface of the welding gun body 1 can be knocked and vibrated reciprocally, so that the welding slag inside the welding gun body 1 can be better vibrated and dropped;

[0041] When the driving assembly 33 is working, the driving part inside the driving housing 331 drives the driving gear 332 to rotate, and the rotation of the driving gear 332 can synchronously drive the meshing driven gear 333 to rotate. Since the driven gear 333 is fixed on the surface of the driving shaft 32, the driving shaft 32 is synchronously rotated.

[0042] When the reciprocating knocking assembly 35 is working, since the cam 354 is fixed at the end of the driving shaft 32, it can synchronously drive the cam 354 to rotate. The horizontal plate 353 on the surface can be moved forward by the rotation of the cam 354. When the horizontal plate 353 moves forward, the vibration head 352 fixed to the sliding block 351 can be synchronously driven to move synchronously, so that when the vibration head 352 moves forward, it can knock on the surface of the welding gun body 1 to vibrate, so that the welding slag inside the welding gun body 1 can be vibrated and dropped in time. Under the spring force of the reset spring 355, when the cam 354 rotates to the other side, the reset spring 355 can apply a reaction force to the surface of the horizontal plate 353, so that the horizontal plate 353 can be tightly fitted to the surface of the cam 354.

[0043] In one embodiment, referring to Figure 3 , Figure 6 ,and Figure 7 The processing mechanism 4 includes a dust collection box 41 fixed to the side wall of the driving assembly 33, the interior of the dust collection box 41 is rotatably connected with a rotating shaft 42 through a bearing, the top of the rotating shaft 42 is fixedly connected with a linkage assembly 43, the driving shaft 32 is used to drive the linkage assembly 43, the surface of the rotating shaft 42 is fixedly connected with a dust collection fan 44, one side of the dust collection box 41 is fixedly connected with a dust collection pipe 45, the bottom of the rotating shaft 42 is fixedly connected with a reciprocating screw rod 46, the surface of the reciprocating screw rod 46 is threadedly connected with a filter pressing plate 47, the filter pressing plate 47 is located inside the dust collection box 41, a guide groove 48 is opened inside the dust collection box 41, the internal sliding connection of the guide groove 48 is a limited slider 49, the limit slider 49 is fixed to the side wall of the filter pressing plate 47, the linkage assembly 43 includes a timing pulley 431 fixed on the surface of the rotating shaft 42 and the driving shaft 32, and a formal connection belt 432 is meshed and connected between the timing pulleys 431.

[0044] By adopting such a scheme, the processing mechanism 4 of the synchronous belt can be driven when the vibration mechanism 3 is working. Driven by the processing mechanism 4, suction can be generated, so that the welding slag dropped by the vibration mechanism 3 can be adsorbed and processed in time, preventing the welding slag from falling on the workpiece surface and affecting the subsequent welding quality.

[0045] During specific operation, the dust box 41 is fixed to the side wall of the driving assembly 33 to ensure the firmness of the dust box 41, and then the linkage assembly 43 on the top of the rotating shaft 42 is set so that when the driving shaft 32 rotates, the timing pulley 431 can be synchronously driven to rotate, and the rotation of the timing pulley 431 can drive the formal connection belt 432 meshed on the surface to rotate, and the rotation of the formal connection belt 432 can drive another set of timing pulleys 431 to rotate, so as to synchronously drive the timing pulley 431 on the top of the rotating shaft 42 to rotate, and the rotation of the rotating shaft 42 can synchronously drive the dust sector 44 to rotate, and through the rotation of the dust sector 44, An adsorption force can be generated inside the dust suction tube 45, so that the welding slag dropped by the vibration of the welding gun body 1 can be timely adsorbed and transported to the inside of the dust suction box 41, so as to prevent the welding slag from falling onto the workpiece and affecting the quality of subsequent welding. The rotation of the rotating shaft 42 can synchronously drive the reciprocating screw 46 to rotate, and the rotation of the reciprocating screw 46 can drive the filter pressure plate 47 to reciprocate, so that the welding slag inside the dust suction box 41 can be compacted and a small part of it can be crushed, so as to increase the storage capacity of the welding slag inside the dust suction box 41, and the rotation of the guide groove 48 can guide and limit the limit slider 49, so as to ensure the limiting performance of the filter pressure plate 47 when it reciprocates up and down.

[0046] In addition, the top of the dust box 41 is fixedly connected to the air outlet, which can discharge the fan, and when the dust tube 45 adsorbs the bottom of the welding gun surface, it can promote convection exchange of heat on the welding gun surface, thereby further accelerating the cooling efficiency of the welding gun. The end of the dust tube 45 is set as a bell mouth, so that it can more easily adsorb welding slag into the dust box 41. The bottom of the dust box 41 is provided with a discharge port, and the surface of the discharge port is provided with a control valve. The welding slag collected by the dust box 41 can be discharged through the discharge port.

[0047] In one embodiment, referring to Figure 4 and Figure 5The rotating mechanism 5 includes a fixed plate 51 fixed to the side wall of the welding gun body 1, a gear ring 52 is connected to the inside of the fixed plate 51, and a rotating gear 53 is meshed and connected to the surface of the gear ring 52. A limiting groove 54 is provided at the bottom of the fixed plate 51, and the top of the driving shaft 32 passes through the limiting groove 54 and is fixed under the rotating gear 53. An annular groove 55 is provided on the side wall of the fixed plate 51, and a sliding rod 56 is slidably connected to the inside of the annular groove 55, and the end of the sliding rod 56 is fixedly connected to the driving assembly 33.

[0048] With such a scheme, the rotating mechanism 5 can assist the vibration mechanism 3 in driving. The vibration mechanism 3 can rotate inside the rotating mechanism 5 and perform a circular rotation along the surface of the welding gun body 1, so that the surface of the welding gun body 1 can be evenly vibrated. In this way, the welding slag in different positions inside the welding gun body 1 can be vibrated and dropped, thereby preventing the problem of insufficient vibration force and failure to drop due to poor vibration position.

[0049] During specific operation, the fixed plate 51 is first fixed to the side wall of the welding gun body 1, and then the rotating gear 53 is meshed with the surface of the gear ring 52. Since the end of the driving shaft 32 passes through the limiting groove 54 and is fixed under the rotating gear 53, when the driving shaft 32 rotates, the rotating gear 53 can rotate and rotate on its own and can also rotate in a circle along the inner ring of the gear ring 52. In this way, the vibration mechanism 3 of the synchronous belt can perform a circular rotation and vibration work along the surface of the welding gun body 1. When the sliding rod 56 slides inside the annular groove 55, it can be connected to the driving component 33, so as to ensure the stability of the vibration mechanism 3 during rotation.
