Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary tools, in particular to a welding device for point - position budgeted trajectory. Background Art

[0002] The point - position budgeted trajectory means that several positioning points are used to fit the weld seam trajectory. That is to say, the moving track of the welding machine relative to the workpiece is determined by several points. For long - strip workpieces with relatively low requirements for welding accuracy, this welding method is widely used.

[0003] In the prior art, for the welding of workpieces with relatively low requirements for welding accuracy, manual welding is adopted. The welding personnel determine the weld seam trajectory according to experience. This welding method has low welding accuracy and is not easy to realize automation.

[0004] Therefore, in the prior art, there is a technical problem of low welding accuracy in the welding process of weld seams with longer dimensions. Summary of the Invention

[0005] A welding device for point - position budgeted trajectory provided by the utility model solves the technical problem of low welding accuracy in the welding process of weld seams with longer dimensions in the prior art.

[0006] Some implementation schemes for solving the above - mentioned technical problems include:

[0007] A welding device for point - position budgeted trajectory includes a frame. A guiding component is slidably arranged on the frame. A welding machine is arranged on the guiding component. A track is arranged on the frame. The guiding component is displaced along the track.

[0008] The track includes several fitters. All the fitters form the track. The fitter is slidably connected to the frame along the width direction of the track. The fitter is provided with a locking nut for locking the fitter to the frame.

[0009] The guiding component includes a frame. A guide rail for guiding the frame is arranged on the frame. The frame is provided with a driver for driving the frame to displace along the track. The driver drives the frame through a gear transmission component. The gear transmission component includes a gear shaft rotatably connected to the frame. The gear shaft is driven by the driver. Each fitter is provided with a tooth groove meshing with the gear shaft. The length of the gear shaft is greater than the sliding distance of the fitter. All the tooth grooves form a rack meshing with the gear shaft.

[0010] The guiding component further includes a slide plate slidably connected to the frame. The welding machine is installed on the slide plate. The slide plate is provided with a positioning plate in contact with the fitter. The sliding direction of the slide plate is parallel to the sliding direction of the fitter.

[0011] Preferably, the fitter includes a column and a spherical head disposed at the upper end of the column. The tooth groove is disposed on the spherical head, and the positioning plate contacts the spherical head.

[0012] Preferably, an external thread for cooperating with the locking nut is disposed at the lower end of the column. The frame is provided with a chute through which the column passes. The chute penetrates the frame. The fitter slides along the chute. A part of the column located in the chute is polygonal. The column is further provided with a baffle for cooperating with the locking nut to lock the position of the column relative to the frame. The baffle and the column are of an integral structure.

[0013] Preferably, the tooth groove is disposed at the top of the spherical head, and the positioning plate and the side portion of the spherical head are in point contact.

[0014] Preferably, the frame is provided with guide rods, and the slide plate is provided with guide holes for cooperating with the guide rods. There are at least two guide rods, and each guide rod cooperates with an independent guide hole.

[0015] Preferably, guides are respectively disposed at both ends of the slide plate. The guides are rotatably connected to both ends of the slide plate, and the rotation axes of the guides are arranged in the vertical direction.

[0016] Preferably, the guide is provided with guide plates. There are two guide plates, and the two guide plates are arranged in a V shape.

[0017] Preferably, the frame is provided with a guide groove for cooperating with the guide rail. The guide rail and the frame are of an integral structure.

[0018] Preferably, a rolling bearing is disposed between the gear shaft and the frame.

[0019] Preferably, the gear shaft is provided with weight-reducing holes for reducing the weight of the gear shaft. The weight-reducing holes are uniformly arranged along the circumferential direction of the gear shaft.

[0020] Compared with the prior art, the present utility model has the following advantages:

[0021] 1. By providing a fitter, and the fitter is slidably connected to the frame. Before welding, the fitter can be used to form a track first, that is, by adjusting the positions of different fitters to form a track identical to the weld track, and then locking all the fitters to the frame. The welding machine displaces along the track through the guiding assembly, and a weld identical to the track can be formed, thereby improving the welding precision.

[0022] 2. By setting up a sliding plate and placing the welding machine on the sliding plate, when the frame slides in the left - right direction, the sliding plate can slide in the front - back direction, so that the welding machine on the sliding plate can weld a weld seam with the same shape as the track. This solution can meet the welding requirements without setting up a complex control system, reducing the welding cost.

[0023] 3. By setting up a lock nut, the lock nut uses friction to lock the fitting device on the machine frame, enabling the position of the fitting device relative to the machine frame to be adjusted, so that tracks of different shapes can be fitted, broadening the application range of the point - position budget track welding device.

The specific embodiments include specific details intended to provide a thorough understanding of the subject technology of the present utility model. However, it will be clear and obvious to those skilled in the art that the subject technology of the present utility model is not limited to the specific details shown herein, and can be practiced without these specific details.

[0037] It can be understood that, herein, relational terms such as "first" and "second" are intended to distinguish one entity or operation from another entity or operation, and are not intended to expressly or implicitly imply any actual relationship or order between these entities or operations.

[0038] The term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0039] Referring to Figures 1 to 6 As shown, a spot budget trajectory welding device includes a frame 1, a guiding assembly 2 is slidably arranged on the frame 1, a welding machine 3 is arranged on the guiding assembly 2, a track 4 is arranged on the frame 1, and the guiding assembly 2 is displaced along the track 4;

[0040] The track 4 includes a plurality of fitters 41, all the fitters 41 form the track 4, the fitters 41 are slidably connected to the frame 1 along the width direction of the track 4, and the fitters 41 are provided with locking nuts 42 for locking the fitters 41 to the frame 1;

[0041] The guiding assembly 2 includes a frame 21, a guide rail for guiding the frame 21 is arranged on the frame 1, the frame 21 is provided with a driver 22 for driving the frame 21 to displace along the track 4, the driver 22 can be a motor, the driver 22 drives the frame 21 through a gear transmission assembly, the gear transmission assembly includes a gear shaft 23 rotatably connected to the frame 21, the gear shaft 23 is driven by the driver 22, each fitter 41 is provided with a tooth groove 24 meshing with the gear shaft 23, the length of the gear shaft 23 is greater than the sliding distance of the fitter 41, and all the tooth grooves 24 form a rack meshing with the gear shaft 23;

[0042] The guiding assembly 2 further includes a sliding plate 25 slidably connected to the frame 21. The welding machine 3 is mounted on the sliding plate 25. The sliding plate 25 is provided with a positioning plate 251 that contacts the fitter 41. The sliding direction of the sliding plate 25 is parallel to the sliding direction of the fitter 41.

[0043] The frame 1 can be formed by welding rod fittings and plate parts.

[0044] In some embodiments, the fitter 41 includes a column 43 and a spherical head 44 provided at the upper end of the column 43. The tooth groove 24 is provided on the spherical head 44. The positioning plate 251 contacts the spherical head 44.

[0045] Before welding, first move each fitter 41 to the target position, and then lock the fitter 41 to the frame 1 through the lock nut 42. Each fitter 41 corresponds to a point position. All the fitters 41 cooperate to fit out the trajectory of the weld seam.

[0046] The tooth grooves 24 on all the fitters 41 form a rack that meshes with the gear shaft 23. Since the fitter 41 displaces in the front-back direction of the frame 1, the fitter 41 does not displace in the left-right direction on the frame 1. The displacement of the fitter 41 does not affect the shape of the rack fitted out. Therefore, the gear shaft 23 can correctly mesh with the fitter 41.

[0047] When the driver 22 drives the gear shaft 23 to rotate, the gear shaft 23 meshes with the tooth groove 24 to drive the frame 21 to move in the left-right direction, thereby realizing the movement of the welding machine 3 in the left-right direction.

[0048] When the frame 21 moves in the left-right direction, the positioning plate 251 contacts the spherical head 44 on the fitter 41. The positioning plate 251 interferes with the spherical head 44. The spherical head 44 drives the sliding plate 25 to move in the front-back direction through the positioning plate 251, and the sliding plate 25 then drives the welding machine 3 to move in the front-back direction, thereby fitting out the shape of the weld seam.

[0049] The track 4 can have one or more tracks. The guiding assembly 2 currently only cooperates with one track 4. The other tracks 4 can be adjusted in shape to prepare for the next welding to improve the welding efficiency.

The frame 1 is provided with a chute 11 through which the column 43 passes. The chute 11 penetrates the frame 1. The fitter 41 slides along the chute 11.

The column 43 is further provided with a baffle 45 that cooperates with the lock nut 42 to lock the position of the column 43 relative to the frame 1. The baffle 45 and the column 43 are of an integral structure.

[0052] The tooth groove 24 is provided at the top of the spherical head 44. The positioning plate 251 is in point contact with the side of the spherical head 44.

The guides 26 are rotatably connected to both ends of the slide plate 25, and the rotation axis of the guides 26 is arranged in the vertical direction. The guides 26 can be rotatably connected to the slide plate 25 by hinges.

[0055] The guide 26 is provided with guide plates 261. There are two guide plates 261, and the two guide plates 261 are arranged in a V shape.

[0056] Refer to Figures 1 to 6 As shown, in some embodiments, the frame 21 is provided with a guide groove that cooperates with the guide rail. The guide rail and the frame 1 are of an integral structure. The frame 1 can include a tabletop. The chute 11 is provided on the tabletop, and a part of the tabletop forms a part of the guide rail.
