Description

Technical Field

[0001] This utility model relates to the field of excavator chassis frame processing technology, and in particular to a hydraulic excavator chassis frame welding device. Background Technology

[0002] The excavator chassis, as the "backbone" and "foundation" of the entire machine, bears the entire weight of the engine and working device, and must also withstand the huge impact, torsion and vibration loads generated during excavation, travel and steering operations.

[0003] The chassis frame is typically composed of various shapes and thicknesses of plates, castings, or forgings, including thick side plates, box-shaped beams, reinforcing ribs, and supports. Its complex structure and large size make it difficult to move when processed using mechanical welding equipment. Therefore, technicians usually assemble the parts to be welded, pre-fix them with clamps, and then stand on the chassis frame to perform the welding. However, this method not only carries certain risks but also makes weld adjustment difficult once personnel are standing, causing numerous inconveniences to the welding work. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a welding device for a hydraulic excavator chassis frame, which performs welding by walking above the chassis frame, which is not only highly safe but also easy to operate.

[0006] To achieve the above objectives, the first aspect of this utility model provides a welding device for a hydraulic excavator chassis frame, comprising: a frame body, a welding mechanism, and a controller. The frame body has two symmetrically arranged wheels on each side, and a drive mechanism is mounted on the frame body, connected to one of the wheels on one side of the frame body. The welding mechanism includes an electric slide module and a welding assembly. The electric slide module is mounted on the frame body, and the welding assembly is mounted on a slider of the electric slide module. The moving direction of the welding assembly is perpendicular to the moving direction of the frame body. An infrared camera is mounted on the frame body, and the controller is mounted on the frame body. The drive mechanism, the welding mechanism, and the infrared camera are respectively connected to the controller.

[0007] In addition, the hydraulic excavator chassis frame welding device proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the drive mechanism includes a drive motor, a first transmission gear set, a transmission component, two second transmission gear sets, and two driven gears. The drive motor and the first transmission gear set are respectively mounted on the frame.

The two second transmission gear sets are mounted on the frame and mesh with the driven gears and the first transmission gear set.

[0009] Specifically, the welding assembly includes a fixed frame, a hydraulic telescopic rod, a plate, multiple telescopic guide rods, an electric gimbal, and a welding torch. The fixed frame is connected to the slider of the electric sliding table module. The hydraulic telescopic rod is mounted on the fixed frame, and the plate is connected to the output end of the hydraulic telescopic rod. The multiple telescopic guide rods are respectively disposed between the fixed frame and the plate.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following describes the hydraulic excavator chassis frame welding device according to an embodiment of the present invention with reference to the accompanying drawings.

[0021] like Figures 1-3 As shown, the hydraulic excavator chassis frame welding device of this utility model embodiment may include: frame 1, welding mechanism 2 and controller 4.

[0022] The frame 1 has two symmetrically arranged wheels 11 on each side, and a drive mechanism 12 is provided on the frame 1. The drive mechanism 12 is connected to one of the wheels 11 on one side of the frame 1.

[0023] The welding mechanism 2 includes an electric slide module 21 and a welding assembly 22.

[0024] The electric slide module 21 is mounted on the frame 1, and the welding assembly 22 is mounted on the slider of the electric slide module 21. The moving direction of the welding assembly 22 is perpendicular to the moving direction of the frame 1.

[0025] It should be noted that the specific structure of the electric slide module 21 described in this embodiment has been disclosed in the prior art and will not be described in detail here.

[0026] It is understandable that the direction of movement of the welding assembly 22 is perpendicular to the direction of movement of the frame 1. When the welding assembly 22 and the frame 1 move together, the welding assembly 22 can present a non-linear welding path on the chassis frame to be welded, thereby expanding the applicability of this device.

[0027] An infrared camera 3 is installed on the frame 1, and a controller 4 is set on the frame 1. The drive mechanism 12, the welding mechanism 2 and the infrared camera 3 are respectively connected to the controller 4.

[0028] It should be noted that the infrared camera 3 can take pictures of the predetermined welding position and transmit the captured information to the controller 4. Relevant technicians can mark the specific welding position and welding direction on the controller 4. After the preparation work is completed, the start switch can be pressed to run the device.

[0029] Specifically, the chassis to be welded is assembled on the fixture. Both the chassis and the fixture are located on the ground. The welding device is pushed so that it is placed above the chassis. The electric slide module 21 is operated through the controller 4 so that the welding component 22 is close to the position to be welded on the chassis.

[0030] Infrared camera 3 captures images of the welding area and transmits the captured information to controller 4. Relevant technicians mark the specific welding positions and welding directions on controller 4. After the preparation work is completed, the start switch can be pressed to run the device.

[0031] The drive mechanism 12 drives the walking wheel 11 to rotate slowly, and the walking wheel 11 drives the frame 1 to move at a constant speed. At the same time, the welding assembly 22 processes the welding position. If the welding position is a curve, the electric slide module 21 can drive the welding assembly 22 to move, thereby processing the welding position.

[0032] After welding is completed, the frame 1 can be moved to one side of the chassis frame on its own. This process is not only highly safe, but also easy to operate.

[0033] In one embodiment of this utility model, such as Figure 2 As shown, the drive mechanism 12 includes a drive motor 121, a first transmission gear set 122, a transmission component 123, two second transmission gear sets 124, and two driven gears 125.

[0034] The drive motor 121 and the first transmission gear set 122 are respectively mounted on the frame 1. The transmission component 123 is connected to the output shaft of the drive motor 121 and one end of the first transmission gear set 122. Two driven gears 125 are respectively connected to the corresponding walking wheels 11. Two second transmission gear sets 124 are mounted on the frame 1. The second transmission gear sets 124 are meshed with the driven gears 125 and the first transmission gear set 122.

[0035] In the above embodiments, the gear structures in the first transmission gear set 122, the second transmission gear set 124 and the driven gear 125 are all bevel gears. The transmission component 123 includes two sprockets and a transmission chain. Its specific connection structure has been disclosed in the prior art, so it will not be described in detail here.

[0036] Specifically, when the drive mechanism 12 is running, the drive motor 121 drives the first transmission gear set 122 to rotate through the transmission component 123, the first transmission gear set 122 drives the driven gear 125 to rotate through the second transmission gear set 124, and the driven gear 125 drives the walking wheel 11 to rotate.

[0037] In one embodiment of this utility model, such as Figure 3 As shown, the welding assembly 22 includes a fixed frame 221, a hydraulic telescopic rod 222, a plate 223, multiple telescopic guide rods 224, an electric gimbal 225, and a welding torch 226.

[0038] The fixed frame 221 is connected to the slider of the electric slide module 21, the hydraulic telescopic rod 222 is set on the fixed frame 221, the plate 223 is connected to the output end of the hydraulic telescopic rod 222, multiple telescopic guide rods 224 are respectively set between the fixed frame 221 and the plate 223, the electric gimbal 225 is set on the plate 223, and the welding torch 226 is installed on the electric gimbal 225.

[0039] In the above embodiment, the hydraulic telescopic rod 222, the electric gimbal 225 and the welding torch 226 are respectively connected to the controller 4. The electric gimbal 225 achieves automatic rotation through a horizontal motor and a vertical motor. The micro switch sets the physical limit and cuts off the power when it rotates to the preset angle to prevent excessive rotation, thereby driving the welding torch 226 to rotate at any angle to process welding positions at different angles.

[0040] It should be noted that the hydraulic telescopic rod 222 can push the welding torch 226 closer to the welding position of the chassis frame for welding.

[0041] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the welding mechanism 2 also includes a purification component 23, which includes a purifier 231, a pipe body 232, and a fume hood 233.

[0042] The fume hood 233 is fitted on the outside of the welding torch 226, the purifier 231 is installed on the welding assembly 22, and the pipe body 232 is located between the purifier 231 and the fume hood 233.

[0043] Understandably, the purification component 23 can purify the welding fumes generated during the welding process, thereby achieving the goal of green production.

[0044] In one embodiment of this utility model, such as Figure 2 As shown, the welding mechanism 2 also includes an auxiliary component 24, which includes a carriage 241 and multiple bundle tube components 242.

[0045] The slide 241 is mounted on the electric slide module 21, and multiple tube bundle components 242 are movably connected to the slide 241. The welding pipe connected to the welding torch 226 passes through the multiple tube bundle components 242.

[0046] It should be noted that the welding pipe described in this embodiment is a flexible hose structure, with one end of the welding pipe connected to the welding torch 226 and the other end of the welding pipe connected to an external gas supply device (argon).

[0047] In the above embodiment, the welding assembly 22 changes due to the change in the welding position of the chassis frame. After the welding assembly 22 moves, the welding pipe is pulled. Under the action of multiple bundled tube components 242, the welding pipe moves under the slide 241. During the process of welding pipe storage and extension, there will be no cross-contamination or confusion, thereby ensuring the normal operation of the device.

[0048] In summary, the hydraulic excavator chassis frame welding device of this utility model uses an infrared camera to identify the welding area and transmits the data information to the controller. The controller sends a signal to the drive mechanism, and the frame moves at a constant speed through the traveling wheels. Combined with the movement of the welding components, this welding device can perform mobile welding above the chassis frame. This process is not only highly safe, but also easy to operate.
