Technical Field

[0001] This application relates to the field of mechanical welding technology, specifically a rapid welding device for vehicle frame engine brackets. Background Technology

[0002] The engine mount of the chassis not only connects the vehicle body and the engine, but also bears various dynamic loads during vehicle operation. Therefore, ensuring its welding quality and structural strength is crucial to the safety and performance of the entire vehicle. Traditional welding equipment can usually only handle workpieces of specific sizes and shapes, and has poor adaptability to workpieces of different models or complex geometries. Adjusting the welding position makes it difficult to ensure the consistency and accuracy of each weld, affecting the quality of the final product. Frequent changes of tooling fixtures and adjustments to welding parameters increase the production cycle and reduce overall production efficiency. Summary of the Invention

[0004] To achieve the above objectives, this application provides the following technical solution: a rapid welding device for a vehicle frame engine bracket, comprising a support frame, a placement plate on the upper surface of the support frame, transverse moving groups on both sides of the placement plate, a side support plate on the transverse moving groups, a longitudinal moving group on one side of the side support plate, a rotary drive component on the longitudinal moving group, a welding group connected to the output end of the rotary drive component, longitudinal and transverse grooves on the placement plate, a transverse clamping seat in the transverse groove, the transverse clamping seat corresponding to a tension adjustment group on the lower surface of the support frame, a lateral clamping seat in the vertical groove, and a lateral clamping seat connected to the output end of an adjusting cylinder on the side of the support frame.

[0005] As a preferred technical solution of this application, the lateral movement group consists of a drive electric cylinder, a lateral linear slide rail and a slider. The drive electric cylinder is disposed on one side of the upper surface of the support frame, the lateral linear slide rail is located on the opposite side of the drive electric cylinder, and the slider is slidably disposed on the lateral linear slide rail.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2(The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0017] Please see Figure 1-3 This application provides a technical solution: a vehicle frame engine bracket quick welding device, including a support frame 8, a placement plate 5 is provided on the upper surface of the support frame 8, a transverse moving group is provided on both sides of the placement plate 5, a side support plate 2 is provided on the transverse moving group, and a longitudinal moving group is provided on one side of the side support plate 2.

[0018] The support frame 8 is the supporting structure of the entire welding device, providing the mounting base for all other components and ensuring the overall stability and robustness of the device during the welding process.

[0019] The placement plate 5 is located directly on the upper surface of the support frame 8 and serves as a working platform for placing the engine bracket of the chassis to be welded.

[0020] The placement plate 5 has crisscrossing grooves, which allow the lateral clamping seat and the side clamping seat 17 to be flexibly adjusted in position, thereby adapting to workpieces of different sizes and shapes, improving the versatility and applicability of the equipment, and meeting the welding needs of workpieces of various specifications.

[0021] The lateral movement group allows the side support plate 2 and the longitudinal movement group thereon to move freely in the X-axis direction, ensuring that the welding head can cover any position that needs to be welded.

[0022] Side support plate 2 provides an installation and support platform for the longitudinal moving assembly.

[0023] The longitudinal moving assembly is provided with a rotary drive component 12, the output end of which is connected to a welding assembly 13. The placement plate 5 is provided with longitudinal and transverse grooves. A transverse clamping seat is provided in the transverse groove. The transverse clamping seat is correspondingly provided with a tension adjustment assembly provided on the lower surface of the support frame 8. A lateral clamping seat 17 is provided in the vertical groove. The lateral clamping seat 17 is connected to the output end of an adjusting cylinder 9 provided on the side of the support frame 8.

[0024] The longitudinal movement assembly is installed on one side of the side support plate 2, providing the welding assembly 13 with the ability to move in the Y-axis direction.

[0025] The longitudinal movement group uses an electric cylinder to precisely control the position of welding group 13, ensuring that welding group 13 can reach any longitudinal position on the workpiece that needs to be welded. This makes the welding process more flexible and suitable for welding workpieces of different lengths and shapes.

[0026] The rotary drive 12 is mounted on the longitudinal moving assembly and its output end is connected to the welding assembly 13. The rotary drive 12 enables the welding assembly 13 to rotate around a fixed point, thereby allowing the welding assembly 13 to approach the welding point from multiple angles. It can handle welding tasks of workpieces with complex geometries, such as curved surfaces or irregular shapes.

[0027] The grooves on the surface of the placement plate 5 provide sliding tracks for the transverse clamping seat and the lateral clamping seat 17, allowing the clamping device to move freely to accommodate workpieces of various sizes and shapes.

[0028] The transverse clamping seat is located in the transverse groove of the placement plate 5, which enables the workpiece to be firmly clamped or released in the transverse direction.

[0029] The lateral clamping seat 17 is located in the vertical groove of the placement plate 5 and is used to fix the side part of the workpiece. When it is necessary to adjust the position of the lateral clamping seat 17, the piston rod of the adjusting cylinder 9 extends and retracts to drive the lateral clamping seat 17 to move along the groove to accommodate workpieces of different widths.

[0030] Furthermore, the lateral movement assembly consists of a drive cylinder 1, a lateral linear slide rail 4, and a slider 3. The drive cylinder 1 is located on one side of the upper surface of the support frame 8, the lateral linear slide rail 4 is located on the opposite side of the drive cylinder 1, and the slider 3 is slidably mounted on the lateral linear slide rail 4.

[0031] The drive cylinder 1 converts the rotational motion generated by the electric motor into linear motion, which is used to push or pull the slider 3 connected to it to move linearly along the transverse linear slide rail 4.

[0032] The transverse linear slide rail 4 provides a guiding function, ensuring that the slider 3 can only move along the predetermined path.

[0033] The slider 3 is the part that directly contacts the transverse linear slide rail 4 and can slide freely along it. A side support plate 2 is connected to the slider 3, allowing the longitudinal moving assembly to move in the X-axis direction.

[0034] Furthermore, side support brackets 11 are provided on both sides of the side support plate 2, and the side support plate 2 is connected to the slider 3 on the transverse moving assembly through the side support brackets 11.

[0035] Side support plate 2 is a vertically installed plate structure that serves to support and install the longitudinal moving assembly.

[0036] Side support brackets 11 are located on both sides of the side support plate 2, fixing the side support plate 2 to the slider 3 of the transverse movement assembly. This ensures that the side support plate 2 has sufficient strength and stability to bear the weight of the side support plate 2 and the components it supports, and allows the side support plate 2 to move smoothly with the slider 3.

[0037] Furthermore, the tension adjustment assembly includes a lead screw motor 7, a lead screw shaft 15, and an adapter sleeve 14. The lead screw shaft 15 is sleeved with a bearing seat disposed on the lower surface of the support frame 8, and the two lead screw shafts 15 are connected by the adapter sleeve 14.

[0038] When it is necessary to adjust the tightness or position, the lead screw motor 7 starts to work and generates rotational motion.

[0039] The rotational motion of the lead screw motor 7 is transmitted to the lead screw shaft 15 through a coupling or other means, causing the lead screw shaft 15 to start rotating as well.

[0040] The spiral groove on the lead screw shaft 15 generates relative movement with the matching nut, thereby converting the rotational motion into linear motion and realizing the position adjustment of the lateral clamping seat.

[0041] The two lead screw shafts 15 are connected by the adapter sleeve 14 to ensure that the two lead screw shafts 15 rotate synchronously, thereby ensuring that the components on both sides move synchronously and maintaining the overall balance and symmetry of the structure.

[0042] Furthermore, the two lead screw shafts 15 rotate in opposite directions.

[0043] Since the two lead screw shafts 15 rotate in opposite directions, when they are driven to rotate at the same speed, the components connected to the two lead screws will move in opposite directions but maintain the same displacement, ensuring that the movement on both sides is symmetrical and synchronous, which facilitates the clamping or release of the workpiece. At the same time, within one action cycle, only one drive source is needed to control the movement in both directions simultaneously, which simplifies the control system and improves efficiency.

[0044] Furthermore, a side plate mounting bracket 16 is provided on one side of the support frame 8, and the side plate mounting bracket 16 is connected to the adjusting cylinder 9.

[0045] Furthermore, the lead screw motor 7 is connected to the mounting side plate 10 located on one side of the support frame 8 via the connecting frame 6.

[0046] In use: Place the chassis engine bracket to be welded on the placement plate 5, positioning it appropriately for subsequent welding operations; slide the lateral clamping seat along the lateral groove on the placement plate 5 to a suitable position, close to one side of the workpiece, and then manually or pneumatically tighten it to initially fix the lateral position of the workpiece; start the lead screw motor 7, which will drive the two lead screw shafts 15 with opposite rotation directions to rotate. Since the lead screw shafts 15 rotate in opposite directions, they will move synchronously but in opposite directions, thereby adjusting the position of the lateral clamping seat to achieve uniform clamping on both sides of the workpiece; similarly, under the action of the adjusting cylinder 9, move the side clamping seat 17 along the vertical groove to the side of the workpiece, so that the side clamping seat 17 contacts and initially clamps the side part of the workpiece; the side clamping seat 17 and the lateral clamping seat ensure that the workpiece will not be deformed or damaged due to over-clamping; at this time, activate the drive electric cylinder 1, which will generate linear motion, pushing the side support plate 2 and its longitudinal moving assembly along the lateral linear slide rail 4 via the slider 3. This positions welding assembly 13 at the X-axis coordinate of the starting welding position; activating the longitudinal movement group allows welding assembly 13 to move precisely along the Y-axis until the desired starting welding position is reached; ensuring the stability and accuracy of welding assembly 13 in the Y-axis direction; once all preparations are complete, the welding power is turned on, and welding assembly 13 begins welding; if it is necessary to approach the welding point from multiple angles, the angle of welding assembly 13 can be adjusted using the rotation drive 12. The rotation drive 12 allows the welding head to rotate around a fixed point, thus adapting to the welding requirements of complex geometries.
