Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, and in particular to welding tooling for tractor brackets. Background Technology

[0002] A tractor is a piece of machinery used for tilling, traction, and transportation. It consists of an engine, transmission, drive system, cab, tires, and other auxiliary equipment.

[0003] In Chinese utility model patents, such as CN222059211U, a welding fixture for a tractor bracket is disclosed. This utility model is constructed by setting a fixed column, a protective cover, a rack, a gear, a first servo motor, and a stabilizing plate. The first servo motor drives the gear to move on the rack. When the gear moves, it drives the stabilizing plate to move through the rotating column. The stabilizing plate drives the protective cover to move, so that the lower surface of the protective cover is in contact with the welding surface, preventing the high-temperature welding slag from splashing out. During welding, the welding rod is consumed and shortened. The rotation of the first servo motor can also adjust the protective cover to move upward, preventing the protective cover from always pressing against the bracket when the welding rod is shortened, which would prevent the welding end of the welding rod from contacting the welding position.

[0004] When the above-mentioned technology is used, the protective cover can block the high-temperature welding slag from splashing out, thereby protecting the safety of the workers. However, when the device is used, it can only move the welding rod vertically in the XY direction through the moving mechanism. It cannot change the welding angle and cannot meet the multi-directional welding requirements of the weld. It is easy to cause uneven welding quality and defects such as incomplete welding and incomplete penetration. In view of this, this application proposes a welding fixture for tractor brackets.

Multiple fixed rods are symmetrically installed on the bottom surface of the worktable. Each fixed rod is slidably connected to a sliding sleeve, and the bottom surface of each sliding sleeve is rotatably connected to the top end of the corresponding third electric telescopic rod.

[0010] Preferably, the clamping mechanism includes two clamping seats, which are symmetrically installed on the top surface of the workbench. A first electric telescopic rod is fixedly installed on the outer side of each clamping seat, and a clamping plate is fixedly installed on the other end of each first electric telescopic rod.

[0011] Preferably, the outer side of the arc-shaped frame is equipped with multiple arc-shaped guide rails, and the sliding seat is slidably connected to each arc-shaped guide rail.

[0012] Preferably, the bottom surface of the workbench is symmetrically equipped with multiple fixed seats, and both ends of each fixed rod are fixedly installed on the side of the fixed seat corresponding to the position.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model uses a moving device, a driving mechanism, an arc-shaped frame, and a sliding seat to move the arc-shaped frame to the welding position. At the same time, the driving mechanism allows the sliding seat to slide circumferentially along the outer side of the arc-shaped frame, which facilitates the adjustment of the welding angle of the welding device, meets the requirements of multi-directional welding of the weld, and thus ensures the quality of the welding.

[0015] 2. This utility model, through devices such as an angle adjustment mechanism, a worktable, a clamping mechanism, and a turntable, enables the support to be stably fixed on the top surface of the worktable by the clamping mechanism, while the angle adjustment mechanism allows the worktable to rotate upward along one axis point, thereby tilting the support. In conjunction with the rotation of the turntable and the adjustment of the welding device angle, the welding in multiple directions can be made more precise, further ensuring the quality of the welding.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] This utility model provides a technical solution: such as Figure 1-3 As shown, the tractor bracket welding fixture includes a work frame 1, a turntable 4 rotatably connected to the top surface of the work frame 1, two gantry frames 2 symmetrically mounted on the top surface of the work frame 1, a moving device 3 jointly mounted on the two gantry frames 2, an assembly seat 6 slidably connected to the bottom surface of the moving device 3, an arc frame 7 fixedly mounted on the bottom surface of the assembly seat 6, a sliding seat 19 slidably connected to the outer side of the arc frame 7, the arc frame 7 drives the sliding seat 19 to slide circumferentially along the outer side of the arc frame 7 through a drive mechanism, a welding device 8 is mounted on the bottom surface of the sliding seat 19, a worktable 5 is mounted on the top surface of the turntable 4, the worktable 5 is mounted on the top surface of the turntable 4 through an angle adjustment mechanism, and a clamping mechanism is mounted on the top surface of the worktable 5.

[0022] It should be noted that the moving device 3 is existing technology, and this technology has been described in detail in the prior art. Its main function is to drive the mounting base 6 to slide along the XY direction, and to adjust the welding device 8 to different positions. At the same time, the welding device 8 should include a lifting device and a protective cover as described in the prior art to block welding slag splash. These are all existing mature technologies and will not be described in detail here. The turntable 4 is driven to rotate by an external drive source.

[0023] The sliding seat 19 is driven by the drive mechanism to slide circumferentially along the outer side of the arc frame 7, thereby adjusting the welding angle of the welding device 8. In conjunction with the clamping mechanism and angle adjustment mechanism on the worktable 5, the tractor bracket can be controlled to rotate and adjust the angle, thus facilitating more precise adjustment of the welding angle as needed.

[0024] Furthermore, the drive mechanism includes a half-gear ring 17, which is fixedly mounted on the top wall of the arc frame 7. A motor 20 is fixedly mounted on the outer side of the sliding seat 19. The output shaft of the motor 20 passes through the sliding seat 19 and is connected to a rotating shaft 22. A gear 18 is mounted on the rotating shaft 22, and the gear 18 meshes with the half-gear ring 17. The motor 20 drives the gear 18 to rotate, thereby allowing the sliding seat 19 to slide.

[0025] Furthermore, the angle adjustment mechanism includes multiple second electric telescopic rods 12, which are symmetrically installed on the top surface of the turntable 4. The top end of each second electric telescopic rod 12 is rotatably connected to the bottom surface of the worktable 5. Multiple third electric telescopic rods 13 are symmetrically installed on the side of the top surface of the turntable 4 away from the second electric telescopic rods 12. Multiple fixed rods 15 are symmetrically installed on the bottom surface of the worktable 5. Each fixed rod 15 is slidably connected to a sliding sleeve 16, and the bottom surface of each sliding sleeve 16 is rotatably connected to the top end of the corresponding third electric telescopic rod 13. The multiple third electric telescopic rods 13 drive one side of the worktable 5 to lift while the support height of the other side remains unchanged, thereby changing the angle of the bracket clamped on the worktable 5.

[0026] Furthermore, the clamping mechanism includes two clamping seats 9, which are symmetrically installed on the top surface of the workbench 5. A first electric telescopic rod 10 is fixedly installed on the outer side of each clamping seat 9, and a clamping plate 11 is fixedly installed on the other end of each first electric telescopic rod 10. The bracket is stably clamped by the two clamping plates 11.

[0027] Furthermore, multiple arc-shaped guide rails 21 are installed on the outer side of the arc-shaped frame 7, and the sliding seat 19 is slidably connected to each arc-shaped guide rail 21. The arc-shaped guide rails 21 provide guidance for the sliding of the sliding seat 19 and limit its movement to prevent it from falling off the arc-shaped frame 7.

[0028] Furthermore, multiple fixed seats 14 are symmetrically installed on the bottom surface of the workbench 5, and both ends of each fixed rod 15 are fixedly installed on the side of the fixed seat 14 corresponding to the position.

[0029] This utility model provides a bracket welding fixture, and its specific working principle is as follows: The operator can first place the bracket on the top surface of the workbench 5, and then activate the two first electric telescopic rods 10 to adjust the two clamping plates 11 to clamp and fix the bracket, thereby fixing the bracket firmly on the top surface of the workbench 5.

[0030] Next, the operator adjusts the sliding position of the assembly seat 6 using the moving device 3. After the adjustment is completed, the motor 20 can be started to drive the rotating shaft 22 to rotate. Through the meshing of the gear 18 and the half gear ring 17, the sliding seat 19 is driven to slide in a ring on the outside of the arc frame 7, thereby adjusting the welding angle of the welding device 8. It can also be used in conjunction with the lifting and lowering of the third electric telescopic rod 13 to drive the worktable 5 to rotate around the top of the second electric telescopic rod 12 as the axis, thereby tilting one side of the bracket. The turntable 4 is driven to rotate by the external drive source, which can assist the welding of the welding device 8 and make the welding angle more precise.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
