Description

Technical Field

[0001] This utility model relates to the field of winch technology, and in particular to a winch support welding fixture. Background Technology

[0002] The winch support is one of the main components of a winch, and its production and processing are mainly completed by welding.

[0003] The winch support mainly consists of a main pipe and several support plates welded to the main pipe. When welding a pair of parallel support plates, it is necessary to ensure that the two are parallel and their side projections coincide.

[0004] Currently, when welding parallel support plates, workers first spot weld one support plate by measuring its dimensions, and then measure and adjust the dimensions of the other support plate based on the first support plate to ensure their parallelism. This operation is not only time-consuming and labor-intensive with low welding efficiency, but also prone to errors due to multiple manual measurements, which affect the parallelism of the two plates.

[0005] Therefore, it is necessary to improve the welding fixtures for winch supports in the existing technology. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects existing in the prior art and provide a welding fixture for a winch bracket that can ensure the parallelism of a pair of parallel support plates during welding.

[0007] To achieve the above technical effects, the technical solution of this utility model is as follows: a welding fixture for a winch support, comprising a base, a first main support frame, a second main support frame, and a side plate limiting frame fixedly mounted on the base. The first and second main support frames are used to support the main pipe of the winch, and the side plate limiting frame is used to limit and fix the side plates of the winch support. The first main support frame is also provided with a support plate leveling assembly. The first main support frame is disposed between two support plates, and parallel abutment planes are provided on both sides of the first main support frame. The support plate leveling assembly is used to press the inner wall of the support plate against the abutment plane. The abutment plane is provided with a through hole, and the mounting holes of the two support plates are coaxially aligned with the through hole.

[0008] According to one embodiment of the present invention, it further includes a first abutting plate and a second abutting plate, the outer sidewalls of the first abutting plate and the second abutting plate being the abutting plane, and the distance between the abutting plane and the first main support frame being adjustable.

[0009] According to one embodiment of the present invention, the first abutting plate is threadedly connected to the first main support frame, and the rotation axis of the first abutting plate is parallel to the axis of the main pipe.

[0010] According to one embodiment of the present invention, the first abutting plate is provided with an internal thread, the second abutting plate is threadedly connected to the first abutting plate, and the second abutting plate and the first abutting plate are arranged coaxially.

[0011] According to one embodiment of the present invention, the support plate leveling assembly includes a first clamping plate and a second clamping plate, with the two support plates clamped between the first clamping plate and the second clamping plate.

[0012] According to one embodiment of the present invention, the distance between the second clamping plate and the first clamping plate can be adjusted.

[0013] According to one embodiment of the present invention, the support plate leveling assembly further includes a U-shaped frame, the first clamping plate is fixedly disposed on one side of the U-shaped frame, and the second clamping plate is threadedly connected to the other side of the U-shaped frame.

[0014] According to one embodiment of the present invention, a limiting protrusion is fixedly provided on the opposite surfaces of the first clamping plate and the second clamping plate, and the limiting protrusion is inserted into the mounting hole of the support plate.

[0015] According to one embodiment of the present invention, the second clamping plate is fixedly provided with a handle that facilitates its rotation.

[0016] The advantages and beneficial effects of this utility model are as follows: The welding fixture for the winch bracket of this utility model is reasonably designed. By setting parallel abutment planes on both sides of the first main support frame, and by using the support plate leveling assembly to press the two support plates against the abutment planes, and by setting the mounting holes of the support plates and the through holes of the abutment planes coaxially, it can be ensured that the two support plates are parallel and their side projections coincide. This avoids the phenomenon of workers constantly manually measuring in the prior art, saving time and effort, and improving the accuracy of welding. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0020] like Figure 1-5 As shown, the winch support welding fixture of the embodiment includes a base 1, a first main support frame 2, a second main support frame 3, and a side plate limiting frame 4 fixedly mounted on the base 1. The first main support frame 2 and the second main support frame 3 are used to support the main pipe 5 of the winch, and the side plate limiting frame 4 is used to limit and fix the side plate of the winch support. The first main support frame 2 is also provided with a support plate leveling assembly. The first main support frame 2 is disposed between two support plates 6. Parallel abutment planes 7 are provided on both sides of the first main support frame 2. The support plate leveling assembly is used to press the inner wall of the support plate 6 against the abutment plane 7. The abutment plane 7 is provided with a through hole 71, and the mounting holes 61 of the two support plates 6 are coaxially arranged with the through hole 71.

[0021] This design ensures the stability of the welded components and avoids displacement deviation: the tooling fixes the first main support frame, the second main support frame, and the side plate limiting frame through the base. The first and second main support frames can stably support the main pipe of the winch, and the side plate limiting frame can limit and fix the side plate of the winch bracket, so that the main pipe and side plate maintain the preset position during the welding process and will not be displaced due to external force or operational shaking, laying the foundation for subsequent welding accuracy.

[0022] To ensure the parallelism of the welded support plates and reduce manual errors: The first main support frame is positioned between the two support plates, with their two abutment planes being parallel. Furthermore, the support plate leveling components firmly press the inner walls of the support plates against these abutment planes. This design eliminates the need for repeated manual measurements and calibrations by workers. The "parallel abutment planes + leveling components pressing" method structurally guarantees the parallelism of the two support plates during welding, avoiding errors caused by manual measurements and improving the accuracy of the support plate welding.

[0023] According to one embodiment of the present invention, it further includes a first abutting plate 72 and a second abutting plate 73, the outer sidewalls of the first abutting plate 72 and the second abutting plate 73 being the abutting plane 7, and the distance between the abutting plane 7 and the first main support frame 2 being adjustable.

[0024] This design ensures the parallelism of the contact planes, laying the foundation for parallel welding of the support plates. The selected content clearly defines the outer walls of the first and second contact plates as the contact planes, which are the reference planes for the inner walls of the support plates to fit together.

[0025] Adjustable spacing between contact surfaces enhances the versatility and adaptability of tooling.

[0026] According to one embodiment of the present invention, the first abutting plate 72 is threadedly connected to the first main support frame 2, and the rotation axis of the first abutting plate 72 is parallel to the axis of the main pipe 5.

[0027] This design allows for adjustable spacing between the abutting planes, accommodating support plates of different thicknesses. The outer wall of the first abutting plate serves as the reference surface for the inner wall of the support plate. Its threaded connection with the first main support frame allows the first abutting plate to be rotated, enabling it to move back and forth along the rotation axis, thereby changing the distance between the abutting plane and the first main support frame.

[0028] According to one embodiment of the present invention, the first abutting plate 72 is provided with an internal thread, and the second abutting plate 73 is threadedly connected to the first abutting plate 72, and the second abutting plate 73 and the first abutting plate 72 are arranged on the same axis.

[0029] This design ensures that the contact planes remain parallel, providing a stable reference for parallel welding of the support plates. The first and second contact plates are "coaxially aligned," meaning that their central axes completely coincide. During adjustment or assembly, no matter how the second contact plate is rotated, its outer wall (i.e., the contact plane where the support plates fit) will not deviate from the common axis and will always remain parallel to the outer wall of the first contact plate.

[0030] According to one embodiment of the present invention, the support plate leveling assembly includes a first clamping plate 81 and a second clamping plate 82, with the two support plates 6 clamped between the first clamping plate 81 and the second clamping plate 82.

[0031] This design forcibly fixes the support plate position, preventing welding displacement. The two support plates are confined between the first and second clamping plates, and the clamping structure provides stable constraint on the support plates from both sides, preventing displacement due to external forces during welding. Compared to traditional manual support plates or simple positioning, this method ensures the support plates remain in the preset welding position, providing a fundamental guarantee for subsequent precise welding.

[0032] The auxiliary support plate is fitted against the abutment plane to ensure parallelism. The document clearly states that the first main support frame has parallel abutment planes on both sides, and the support plate needs to be pressed against these planes by the leveling components to ensure parallelism. When the first and second clamping plates clamp the support plate, they will exert a compressive force on the support plate in the direction of the abutment plane. The inner wall of the auxiliary support plate is tightly fitted against the abutment plane. Since the abutment planes themselves are parallel, the two support plates that are clamped, fixed, and fitted against the plane can naturally ensure that they are parallel to each other structurally, avoiding deviations during manual adjustment.

[0033] Simplified positioning operation and improved welding efficiency: Traditional welding requires workers to repeatedly measure the spacing between support plates and calibrate parallelism, which is cumbersome and time-consuming. This design eliminates the need for continuous manual calibration. Simply placing the support plate between the two clamping plates quickly completes the initial positioning, reducing manual measurement and adjustment steps, significantly saving operation time, and improving overall welding efficiency.

[0034] According to one embodiment of the present invention, the distance between the second clamping plate 82 and the first clamping plate 81 can be adjusted.

[0035] This design allows for the adaptation of support plates of different specifications, improving the versatility of the tooling. The document clearly states that the tooling is required for welding the support plates of the winch bracket, and the thickness and dimensions of the support plates may vary for different models of winch brackets.

[0036] The ability to flexibly adjust the clamping force, balancing stability and support plate protection, essentially relies on the controllability of the clamping force.

[0037] According to one embodiment of the present invention, the support plate leveling assembly further includes a U-shaped frame 8, the first clamping plate 81 is fixedly disposed on one side of the U-shaped frame 8, and the second clamping plate 82 is threadedly connected to the other side of the U-shaped frame 8.

[0038] This design provides a stable clamping reference, fixing the first clamping plate to one side to form a fixed reference surface. During welding, one side of the support plate can directly adhere to the fixed first clamping plate, avoiding positioning deviations caused by loose clamping plates. At the same time, the overall structure of the U-shaped frame has high strength, resisting external forces from welding vibrations or operational contact, preventing deformation of the entire clamping assembly, providing a stable positioning environment for the support plate, and structurally reducing the risk of support plate displacement.

[0039] Simplifying the loading and unloading of support plates and improving welding efficiency, the "U"-shaped opening structure of the U-shaped frame has the advantage of accommodating space. The support plate can be directly inserted between the first and second clamping plates from the opening without disassembling the entire assembly. At the same time, the threaded connection of the second clamping plate is easy to adjust, and clamping or loosening operations can be completed without complicated tools.

[0040] According to one embodiment of the present invention, a limiting protrusion ring 83 is fixedly provided on the opposite surfaces of the first clamping plate 81 and the second clamping plate 82, and the limiting protrusion ring 83 is inserted into the mounting hole 61 of the support plate 6.

[0041] This design enables rapid coaxial positioning of the mounting holes, ensuring assembly accuracy. After the limiting protrusion is inserted into the mounting hole of the support plate, it can directly guide the mounting holes of the two support plates to quickly align with the preset position of the clamping plate, thereby ensuring that the mounting holes of the support plates are precisely coaxial with the through holes of the mating plane. This eliminates the need for workers to manually measure and calibrate repeatedly, avoiding subsequent assembly problems caused by misalignment of the mounting holes from the source.

[0042] The auxiliary fixing plate posture reduces the risk of tilting if only the clamping force of the clamping plate is used for fixing.

[0043] According to one embodiment of the present invention, the second clamping plate 82 is fixedly provided with a handle 84 for easy rotation.

[0044] This design improves ease of operation and reduces reliance on tools. The second clamping plate is threadedly connected to the U-shaped frame, and the spacing needs to be adjusted by rotation.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
