Description

Technical Field

[0001] This utility model relates to the field of engine processing technology, specifically to an engine mounting bracket processing and welding device. Background Technology

[0002] Engine mounts are key components in automotive powertrain systems that connect the engine to the chassis. Their core functions are to isolate vibration, support weight, and control displacement, directly affecting the vehicle's NVH performance (noise, vibration, and harshness) and reliability.

[0003] The utility model patent with authorization announcement number CN219026486U discloses a welding fixture for an automotive engine mounting bracket, including a base, a support plate, an adjustment mechanism, and a clamping mechanism. The support plate is located above the base, the adjustment mechanism is slidably mounted on the top of the support plate, and the clamping mechanism is mounted on the top of the adjustment mechanism. It also includes a height adjustment mechanism and a fixing mechanism. The height adjustment mechanism includes two sleeve seats, two rotary motors, two fixing brackets, two lead screws, two threaded sleeves, two sets of sliders, and two sliding support rods. The height adjustment mechanism is mounted on the top of the base, and the top of the height adjustment mechanism is fixedly connected to the bottom of the support plate. The fixing mechanism is mounted on the clamping mechanism.

[0004] As shown in the above utility model, existing welding fixtures can more firmly fix the engine mount on the sliding seat, improving welding safety. The height of the engine mount can be adjusted by adjusting the height of the support plate through a height adjustment mechanism. However, the height adjustment of existing welding fixtures relies on a screw and nut mechanism, and the angle adjustment is only achieved by horizontal movement through a slide rail and telescopic cylinder. It lacks rotational adjustment and precise height control of the engine mount, making it difficult to adapt to the welding requirements of complex curved surfaces. This can easily lead to welding position deviations or angle limitations, affecting welding quality. Moreover, existing clamping mechanisms fix the workpiece from the left, right, and top using a bidirectional screw and a fixing cylinder. However, the clamping plate is rigidly fixed when in contact with the workpiece, making it impossible to adjust the workpiece angle while clamped. Furthermore, the rubber pads only provide simple cushioning, and high-frequency welding vibrations may cause slight displacement of the workpiece, affecting welding accuracy. In addition, the adjustment steps are cumbersome, requiring multiple manual calibrations. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an engine mount bracket processing and welding device, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an engine mount bracket processing and welding device, comprising:

[0007] A frame, the top of which is provided with a mounting plate for mounting welding equipment, and the top edge of the frame is provided with a protective frame for protecting the welding equipment;

[0008] A welded component, which is installed on one end of the upper surface of the mounting plate, is used for welding the engine mount bracket;

[0009] An adjusting component, located at the other end of the upper surface of the mounting plate, is used for installing and adjusting the engine mount bracket;

[0010] A clamping element is mounted on an adjusting element, and the clamping element, in conjunction with the adjusting element, is used to clamp and limit the engine mount bracket.

[0011] Preferably, a transformer is installed at one end of the upper surface of the frame, and an exhaust fan is installed on one side of the top of the transformer for dust extraction.

[0013] Preferably, the adjusting component includes an adjusting plate disposed at the other end of the upper surface of the mounting plate. One side of the adjusting plate is connected to the output end of the fine-tuning cylinder. The lower surface of the adjusting plate is connected to the mounting plate via a linear guide rail. A motor is fixed to one end of the lower surface of the adjusting plate. Both ends of the upper surface of the adjusting plate are movably connected to pulleys. The output end of the motor is connected to one of the pulleys. The two pulleys are connected by a conveyor belt. A pressing mechanism is installed on one side of the upper surface of the adjusting plate for pressing the conveyor belt.

[0014] Preferably, a transmission column is fixed to the middle of another pulley, and a movable sleeve is sleeved on the outer side of the upper end of the transmission column. The transmission column and the movable sleeve are connected by a slider and a slide groove. An adjusting frame is movably connected to the outer side of the movable sleeve through a bearing. Guide rods are connected through both ends of the adjusting frame. The bottom end of the guide rod is connected to a mounting plate. Lifting plates are fixed to both ends of the adjusting frame. A lifting cylinder is provided below the lifting plate and is mounted on the mounting plate.

[0015] Preferably, the clamping component includes a mounting bracket fixed to the other end of the upper surface of the mounting plate, a clamping cylinder fixed to the top of the mounting bracket, a pressure plate connected to the output end of the clamping cylinder, a bonding plate movably connected to the lower surface of the pressure plate via a rotary bearing, the bonding plate being located directly above the movable sleeve, a guide post fixed to one end of the upper surface of the pressure plate, and the upper end of the guide post being connected through a guide groove opened at the top of the mounting bracket.

[0016] Beneficial effects

[0017] This utility model provides an engine mount bracket processing and welding device. Compared with the prior art, it has the following advantages:

[0018] 1. The engine mount processing and welding device drives the transmission column to rotate through the motor, pulley and conveyor belt of the adjusting component, and moves the adjusting frame up and down with the lifting cylinder to realize the synchronous adjustment of the rotation angle and height of the engine mount; the fine-tuning cylinder can further correct the welding position to form a three-dimensional adjustment system, which can accurately align complex welds, significantly improve welding adaptability and accuracy, and is especially suitable for multi-curved surface and multi-angle welding processes.

[0019] 2. The engine mount welding device uses a clamping cylinder to press down the bonding plate. The bonding plate and the pressure plate are connected by a rotary bearing. This allows for stable clamping of the workpiece through elastic bonding (the bonding plate and the movable sleeve cooperate), while also allowing the workpiece to rotate freely with the movable sleeve in the clamped state. This solves the contradiction between clamping rigidity and angle adjustment flexibility. The cooperation between the guide column and the guide groove ensures no deviation during the clamping process. The rubber bonding surface reduces damage to the workpiece surface. At the same time, the linkage design of the lifting cylinder and the adjustment frame keeps the workpiece stable during height adjustment, effectively reducing the risk of displacement caused by welding vibration and improving the finished product qualification rate.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3 This utility model provides two technical solutions:

[0026] First embodiment: An engine mount bracket processing and welding device includes a frame 1, a welding component 2, an adjusting component 3, and a clamping component 4. The top of the frame 1 is provided with a mounting plate 11 for mounting welding equipment. The top edge of the frame 1 is provided with a protective frame for protecting the welding equipment. A transformer 12 is installed at one end of the upper surface of the frame 1. An exhaust fan 13 is installed on one side of the top of the transformer 12 for exhausting dust.

[0027] Specifically, the welding component 2 is installed on one end of the upper surface of the mounting plate 11 for welding the engine mount bracket. The welding component 2 includes a fixed plate 21 fixed to one end of the upper surface of the mounting plate 11. A telescopic cylinder 22 is fixed on one side of the fixed plate 21. The output end of the telescopic cylinder 22 is connected to a movable plate 23. The movable plate 23 is movably mounted on the fixed plate 21 via a linear guide rail. An mounting block 24 is mounted on the movable plate 23. A welding head 25 is mounted on the mounting block 24. A fine-tuning cylinder 26 is mounted at the bottom of the fixed plate 21. The output end of the fine-tuning cylinder 26 is connected to the adjusting component 3.

[0028] More specifically, the adjusting component 3 is located at the other end of the upper surface of the mounting plate 11 for installing and adjusting the engine mount bracket. The adjusting component 3 includes an adjusting plate 31 located at the other end of the upper surface of the mounting plate 11. One side of the adjusting plate 31 is connected to the output end of the fine-tuning cylinder 26. The lower surface of the adjusting plate 31 is connected to the mounting plate 11 via a linear guide rail, allowing the adjusting plate 31 to make a certain displacement under the drive of the fine-tuning cylinder 26. A motor 32 is fixed at one end of the lower surface of the adjusting plate 31, and pulleys are movably connected to both ends of the upper surface of the adjusting plate 31. The output end of the motor 32 is connected to one of the pulleys, and the two pulleys are connected by a conveyor belt 33. A clamping mechanism 34 is installed on one side of the upper surface of the adjusting plate 31 to clamp the conveyor belt 33. A transmission mechanism is fixed in the middle of the other pulley. The upper outer side of the moving column 35 and the transmission column 35 is fitted with a movable sleeve 36. The transmission column 35 and the movable sleeve 36 are connected by a slider and a groove. The outer side of the movable sleeve 36 is movably connected to an adjusting frame 37 through a bearing. Both ends of the adjusting frame 37 are connected to guide rods 38. The bottom end of the guide rods 38 is connected to the mounting plate 11. Both ends of the adjusting frame 37 are fixed with lifting plates 39. A lifting cylinder 310 is set below the lifting plate 39 and is mounted on the mounting plate 11. The motor 32 drives the transmission column 35 to rotate through a pulley and a conveyor belt 33. The transmission column 35 drives the movable sleeve 36 to rotate. The lifting cylinder 310 and the lifting plate 39 cooperate to drive the adjusting frame 37 to move up and down, thereby driving the movable sleeve 36 to move up and down, without affecting the rotation of the movable sleeve 36 by the transmission column 35.

[0029] The second embodiment differs from the first embodiment mainly in that: the clamping member 4 is mounted on the adjusting member 3. The clamping member 4, in conjunction with the adjusting member 3, is used to clamp and limit the engine mount bracket. The clamping member 4 includes a mounting bracket 41 fixed to the other end of the upper surface of the mounting plate 11. A clamping cylinder 42 is fixed to the top of the mounting bracket 41. A pressure plate 43 is connected to the output end of the clamping cylinder 42. A fitting plate is movably connected to the lower surface of the pressure plate 43 via a rotary bearing. The fitting plate is located directly above the movable sleeve 36. The upper surface of the pressure plate 43... A guide post 44 is fixed to one end of the surface. The upper end of the guide post 44 is connected to the guide groove opened on the top of the mounting bracket 41. The pressing cylinder 42 drives the pressure plate 43 to move downward. The fitting plate on the pressure plate 43 cooperates with the movable sleeve 36 to press and limit the engine mount bracket. The guide post 44 and the guide groove cooperate to keep the pressure plate 43 moving vertically up and down. The movable setting of the fitting plate allows the movable sleeve 36 to drive the engine mount bracket to rotate to a certain angle, which facilitates the welding head 25 to weld the engine mount bracket.

[0030] When this device is in operation, the engine mount bracket is placed on the movable sleeve 36 of the adjusting component 3. Simultaneously, welding parameters such as current and voltage are adjusted according to welding process requirements. Power supply is regulated via the transformer 12 on the frame 1, activating the motor 32 in the adjusting component 3. The motor 32 drives the pulley to rotate, which in turn rotates the conveyor belt 33. The conveyor belt 33 drives the connected transmission column 35 to rotate. The transmission column 35, through the cooperation of the slider and the slide groove, drives the movable sleeve 36 to rotate, achieving rotational adjustment of the mount bracket to adjust the welding angle. When the height of the mount bracket needs to be adjusted, the lifting cylinder 310 is activated. The lifting cylinder 310 pushes the lifting plate 39, which drives the adjusting frame 37 to move up and down along the guide rod 38. Since the adjusting frame 37 and the movable sleeve 36 are movably connected via bearings, the movable sleeve 36 can continue to rotate during the up-and-down movement of the adjusting frame 37, thereby achieving height adjustment of the mount bracket to a suitable welding position. After the mount bracket is adjusted to the correct position, the clamping cylinder 42 in the clamping component 4 is activated. The clamping cylinder 42 pushes the pressure plate 43 downward along the guide post 44, causing the bonding plate on the lower surface of the pressure plate 43 to approach the movable sleeve 36. When the bonding plate contacts the suspension bracket, under the continuous action of the clamping cylinder 42, the bonding plate and the movable sleeve 36 fit tightly together, clamping and limiting the suspension bracket. Since the bonding plate is movably connected to the pressure plate 43 via a rotary bearing, when the movable sleeve 36 drives the suspension bracket to rotate, the bonding plate can rotate accordingly without affecting the angle adjustment of the suspension bracket, while ensuring that the suspension bracket will not shift during welding. The telescopic cylinder 22 in the welding component 2 is activated, pushing the movable plate 23 along the linear guide rail towards the suspension bracket, bringing the welding head 25 mounted on the movable plate 23 closer to the suspension bracket. Once the welding head 25 reaches the appropriate welding position, welding operations begin. During welding, if fine adjustments to the welding position are needed, the fine-tuning cylinder 26 at the bottom of the fixed plate 21 can be activated. The fine-tuning cylinder 26 pushes the adjusting component 3, causing the suspension bracket to make a slight displacement, ensuring that the welding head 25 can be accurately welded in the predetermined position, thus guaranteeing welding quality. Simultaneously, the exhaust fan 13 on the frame 1 starts working to promptly remove fumes generated during welding, maintaining a clean working environment. After welding is completed, the welding power is first turned off, stopping the welding head 25. Then, the clamping cylinder 42 is operated sequentially to raise the pressure plate 43, the lifting cylinder 310 to lower the adjusting bracket 37, and the telescopic cylinder 22 to return the movable plate 23 to its initial position, allowing the welded engine suspension bracket to be removed.
