Description

Technical Field

[0001] The present invention relates to the technical field of vehicle welding, and particularly relates to a welding device for the frame of a garbage truck. Background Art

[0002] With the development of frame welding technology, frame welding structural parts in different regions often require different welding processes. For some parts of the frame, a welding process with high strength and high penetration may be required, while for some parts in other regions, a welding process with fine and low heat input may be more suitable. This requires that the welding torch corresponding to different welding processes can be conveniently and flexibly switched during the welding process.

[0003] Existing frame welding equipment welds by using different welding processes for different regions. During the welding process, the operator needs to frequently replace the welding torch equipment. The replacement process requires manual replacement and adjustment of the equipment, and the operation is very cumbersome. At the same time, the tip of the welding torch is easily affected by oxidation and overheating during the welding process. In the high-temperature welding environment, the tip is exposed to the air for a long time and is easily oxidized, thereby reducing its performance and service life. Therefore, the present application provides a welding device for the frame of a garbage truck to meet the requirements. Summary of the Invention

[0040] As Figures 1 to 10 shown, an embodiment of the present invention provides a frame welding device for a garbage transport vehicle, including an auxiliary waist guard 1. One side of the auxiliary waist guard 1 is provided with an auxiliary folding arm 1 2. The end of the auxiliary folding arm 1 2 is provided with an auxiliary folding arm 2 3. The end of the auxiliary folding arm 2 3 is provided with a mounting bracket 4. One side of the auxiliary waist guard 1 is provided with a control handle 9. The end of the mounting bracket 4 is installed with a switching component 5. The switching component 5 is used for an operator to switch the welding torch 76. The inner side of the switching component 5 is installed with a triggering component 6. The triggering component 6 is used to trigger the extension of the welding module in the switching component 5. The inner side of the switching component 5 is installed with a quick-release component 7. The quick-release component 7 is used for the quick installation between the welding torch 76 and the bracket module. One side of the mounting bracket 4 is installed with a protection component 8. The protection component 8 is used to apply a protective agent to the surface of the welding torch head.

[0041] As Figures 4 to 6 and Figure 10 shown, the switching component 5 includes an electric control turntable 51. The electric control turntable 51 is installed at the end of the mounting bracket 4 and rotates at the end of the mounting bracket 4. Four mounting boxes 52 are equally angularly distributed and installed at the end of the electric control turntable 51. The end of the mounting box 52 is installed with an auxiliary cover plate 53. One side of the auxiliary cover plate 53 is connected with a guide wheel 54. The guide wheel 54 slides inside the mounting box 52. One side of the auxiliary cover plate 53 is connected with a connecting rod 1 55. The connecting rod 1 55 is on the inner wall bracket of the mounting box 52. The tail end of the connecting rod 1 55 is connected to the inner wall of the mounting box 52. One side of the connecting rod 1 55 is connected with a spring 56. The tail end of the spring 56 is connected to the inner wall bracket of the mounting box 52. One side of the connecting rod 1 55 is connected with a synchronous pulley group 57.

[0042] By setting the switching component 5, first, the operator wears the auxiliary waist protector 1. The auxiliary folding arm 1 and the auxiliary folding arm 2 can rotate on the installation plane, and the mounting bracket 4 at the end of the auxiliary folding arm 2 can rotate, so that the mounting bracket 4 can remain relatively horizontal. Subsequently, according to different welding structural part areas, different welding process torches 76 are selected. The electric control turntable 51 is controlled to rotate through the control handle 9, driving the four mounting boxes 52 to rotate, so that the mounting boxes 52 can be switched. The mounting box 52 can rotate on the inner wall of the mounting box 52 through the connecting rod 1 55. During the process of the connecting rod 1 55 driving the auxiliary cover plate 53 to rotate, the guide wheel 54 at the bottom of the auxiliary cover plate 53 slides on the track on the inner wall of the mounting box 52, so that the auxiliary cover plate 53 at the end of the mounting box 52 can be opened. At this time, the spring 56 is in an unloaded state, and the spring 56 is only stretched and stressed during the process of cooperating with the rotation of the connecting rod 1 55. When the sliding movement of the guide wheel 54 is completed, through the restoring tendency during the stretching and stressing process of the spring 56, the pulling force formed on the connecting rod 1 55 realizes the auxiliary positioning of the auxiliary cover plate 53 to be able to rotate to the inner top end of the mounting box 52, preventing the situation that the auxiliary cover plate 53 cannot be fully opened due to insufficient driving force.

[0043] As Figures 4 to 7 and Figure 10 shown, the trigger component 6 includes a fixed rod 61. The fixed rod 61 is nested and installed inside the electric control turntable 51. The end of the fixed rod 61 is connected with a cam 62. The cam 62 is nested inside the four mounting boxes 52. Four contact rods 1 63 are equally distributed and installed on the outer side of the cam 62. The four contact rods 1 63 are in contact with the surface of the cam 62. Each contact rod 1 63 is respectively nested inside the corresponding mounting box 52. The tail end of the contact rod 1 63 is connected with a connecting rod 2 64. The end of the connecting rod 2 64 is connected with a rack 65. The rack 65 rotates at the end of the connecting rod 2 64. The rack 65 slides on the inner wall of the mounting box 52. The rack 65 meshes with a gear 66. The gear 66 is installed on the rotating bracket of the connecting rod 1 55.

[0044] By setting the trigger component 6, during the rotation of the electric control turntable 51 driving the four mounting boxes 52, the cam 62 connected to the fixed rod 61 remains stationary. The cam 62 is nested inside the long groove on the bottom wall of the mounting box 52. When the mounting box 52 rotates to the uppermost position, during the rotation of the mounting box 52, the contact rod one 63 inside the mounting box 52 contacts the highest point of the cam 62, causing the contact rod one 63 to slide upward inside the corresponding mounting box 52, pushing the connecting rod two 64, thereby enabling the rack 65 to slide on the inner slide rail of the mounting box 52. The rack 65 meshes with the gear 66, driving the connecting rod one 55 to rotate on the rotating bracket on the inner wall of the mounting box 52. The spring 56 is stretched during the rotation of the connecting rod one 55. The connecting rod one 55 drives the auxiliary cover plate 53 to rotate inside the mounting box 52. The guide wheel 54 located at the bottom end of the auxiliary cover plate 53 slides on the auxiliary track on the inner wall of the mounting box 52, so that the auxiliary cover plate 53 at the end of the mounting box 52 can be opened.

[0045] As Figure 8 and Figure 10 shown, the quick-release component 7 includes a mounting seat 71. The mounting seat 71 is installed inside the mounting box 52. One side of the mounting seat 71 is connected to one of the synchronizing wheels in the synchronizing wheel group 57. Four clamping plates 72 are equiangularly distributed and installed at the end of the mounting seat 71. Each clamping plate 72 rotates inside the inner side of the end of the mounting seat 71. A contact rod two 73 is installed on one side of each clamping plate 72. The outer sides of the four contact rods two 73 contact the trigger block 74. The trigger block 74 is installed inside the mounting seat 71. The trigger block 74 slides inside the mounting seat 71. A welding torch seat 75 is installed between the four clamping plates 72. A welding torch 76 is installed at the top of the welding torch seat 75 through bolts. The tail end of the trigger block 74 is connected to an inclined block one 77. The inclined block one 77 contacts the inclined block two 78. The tail end of the inclined block two 78 is connected to a fastening bolt 79. The inclined block two 78 rotates inside the mounting seat 71. The fastening bolt 79 rotates at the end of the inclined block two 78.

[0046] By setting the quick-release assembly 7, the operator can use different metal welding materials according to the different welding positions of the frame and the welding gun head selected before the welding process, connect the welding gun head with the matching welding gun 76, and use standard bolts to fix the handle part of the welding gun 76 on the welding gun seat 75. Then the operator can hold the handle part of the welding gun 76 and align the welding gun seat 75 between the four clamping plates 72 located at the end of the mounting seat 71. Then the operator can insert the fastening bolt 79 and the inclined block 2 78 into the inner side of the mounting seat 71. The fastening bolt 79 engages with the side wall thread of the mounting seat 71 to drive the inclined block 2 78 to move on the inner side of the mounting seat 71. The inclined block 2 78 contacts the inclined surface of the inclined block 1 77, so that the inclined block 1 77 moves upward in the vertical direction. The inclined block 1 77 drives the trigger block 74 to move vertically upward, so that the outer surface of the trigger block 74 contacts the ends of the four contact rods 2 73 respectively, and the four contact rods 2 73 are triggered. The resistance force on the surface of block 74 causes the corresponding clamping plate 72 to rotate on the inner side of the end of the mounting seat 71, so that the claw parts of the four clamping plates 72 can be stuck on the step of the welding gun seat 75, so that the welding gun seat 75 can be installed at the top of the mounting seat 71. When the connecting rod 55 is rotated, it can be transmitted through the synchronous wheel group 57, so that the mounting seat 71 can rotate synchronously with the rotation of the connecting rod 55. At the same time, the operator can also rotate the fastening bolt 79 in the opposite direction so that the fastening bolt 79 engages with the side wall thread of the mounting seat 71 to drive the inclined block 2 78 to move to the initial position, so that the inclined block 1 77 drives the trigger block 74 to move in the direction of the initial position, so that the four contact rods 2 73 are no longer subjected to the resistance force from the surface of the trigger block 74, and the four clamping plates 72 are no longer clamped on the welding gun seat 75, so that the operator can remove the welding gun 76 separately, which can be used when welding in a narrow space.

[0047] like Figures 9 to 10 As shown, the protection component 8 includes a bevel gear ring 81, which is installed at the end of the cam 62, and the bevel gear ring 81 is respectively meshed with one of the bevel gears in the four bevel gear groups 82, and a storage box 83 is installed at the end of one of the bevel gears in each bevel gear group 82, and the storage box 83 is installed at the bottom end of the installation box 52, and the output end of one of the bevel gears in the bevel gear group 82 is connected to a reciprocating screw 84, and a slider 85 is installed on the outer side of the reciprocating screw 84, and the slider 85 slides on the outer side of the reciprocating screw 84, and two elastic rods 86 are installed on the inner side of the slider 85, and two auxiliary rods 87 are symmetrically nested on the inner side of the slider 85, and the two auxiliary rods 87 are respectively installed on the inner bottom wall of the storage box 83.

[0048] By setting the protection component 8, during the rotation and switching process of the four mounting boxes 52 driven by the electric control turntable 51, the storage box 83 rotates following the corresponding mounting box 52. One bevel gear in the bevel gear set 82 at the bottom end of the storage box 83 meshes with the bevel gear ring 81 at the end of the cam 62. The output end of the other bevel gear in the bevel gear set 82 drives the reciprocating lead screw 84 to rotate. The slider 85 slides on the outside of the reciprocating lead screw 84 under the guidance of the two auxiliary rods 87. When the two elastic rods 86 are inside the storage box 83, the surfaces of the elastic rods 86 will be covered with antioxidant paste. By rotating the reciprocating lead screw 84, the elastic rods 86 evenly apply the antioxidant paste on the outside of the tip of the welding torch 76. The elastic rods 86 can closely adhere to the outside of the tip of the welding torch 76, which can effectively prevent the tip of the welding torch 76 from being oxidized. At the same time, during the welding operation, this protective film formed by the antioxidant paste can also play a certain role in assisting heat dissipation. Part of the heat generated during welding will be absorbed and conducted by this protective film, thus avoiding the situation that the tip of the welding torch 76 deteriorates or is damaged due to overheating.

[0049] The working principle of the technical solution provided by the present invention is as follows:

[0050] First, the operator wears the auxiliary waist protector 1. The auxiliary folding arm one 2 and the auxiliary folding arm two 3 can rotate on the installation plane. The mounting bracket 4 at the end of the auxiliary folding arm two 3 can rotate, so that the mounting bracket 4 can be kept relatively horizontal. Subsequently, according to different regions of the frame welding structural parts or different materials, different welding process welding torches 76 are selected.

[0051] The operator controls the electric control turntable 51 to rotate through the control handle 9, driving the four mounting boxes 52 to rotate, so as to be able to switch the mounting boxes 52. The mounting box 52 can rotate on the inner wall of the mounting box 52 through the connecting rod one 55. During the rotation of the connecting rod one 55 driving the auxiliary cover plate 53, the guide wheel 54 at the bottom end of the auxiliary cover plate 53 slides on the track on the inner wall of the mounting box 52, so that the auxiliary cover plate 53 at the end of the mounting box 52 can be opened. At this time, the spring 56 is in an unloaded state. The spring 56 is only stretched and stressed during the process of cooperating with the rotation of the connecting rod one 55. When the sliding movement of the guide wheel 54 is completed, through the restoring tendency during the stretching and stressing process of the spring 56, the pulling force formed on the connecting rod one 55 realizes the auxiliary positioning of the auxiliary cover plate 53 to be able to rotate to the inner top end of the mounting box 52, preventing the situation that the auxiliary cover plate 53 cannot be fully opened due to insufficient driving force.

[0052] When the electric-controlled turntable 51 drives the four installation boxes 52 to rotate, the cam 62 connected to the fixing rod 61 is fixed, and the cam 62 is nested in the inner side of the long groove on the bottom wall of the installation box 52. When the installation box 52 rotates to the top, during the rotation of the installation box 52, the contact rod 1 63 on the inner side of the installation box 52 contacts the highest point of the cam 62, so that the contact rod 1 63 slides upward on the inner side of the corresponding installation box 52, pushing the connecting rod 2 64, so that the rack 65 slides on the inner side slide rail of the installation box 52, and the rack 65 and the gear 66 engage with each other, driving the connecting rod 1 55 to rotate on the inner wall rotating bracket of the installation box 52, and the spring 56 is stretched during the rotation of the connecting rod 1 55, and the connecting rod 1 55 drives the auxiliary cover plate 53 to rotate on the inner side of the installation box 52, and the guide wheel 54 at the bottom end of the auxiliary cover plate 53 slides on the track on the inner wall of the installation box 52, so that the auxiliary cover plate 53 at the end of the installation box 52 can be opened.

[0053] The operator can use different metal welding materials according to the different welding positions of the frame and select the welding gun head before the welding process, connect the welding gun head with the matching welding gun 76, and use standard bolts to fix the handle part of the welding gun 76 on the welding gun seat 75. Then the operator can hold the handle part of the welding gun 76 and align the welding gun seat 75 between the four clamping plates 72 located at the end of the mounting seat 71. Then the operator can insert the fastening bolt 79 and the inclined block 2 78 into the inner side of the mounting seat 71. The fastening bolt 79 engages with the side wall thread of the mounting seat 71 to drive the inclined block 2 78 to move on the inner side of the mounting seat 71. The inclined block 2 78 contacts the inclined surface of the inclined block 1 77, so that the inclined block 1 77 moves upward in the vertical direction. The inclined block 1 77 drives the trigger block 74 to move vertically upward, so that the outer surface of the trigger block 74 contacts the ends of the four contact rods 2 73 respectively, and the four contact rods 2 73 are affected by the surface of the trigger block 74. The resistance force causes the corresponding clamping plate 72 to rotate inside the end of the mounting seat 71, so that the claw parts of the four clamping plates 72 can be stuck on the steps of the welding gun seat 75, so that the welding gun seat 75 can be installed on the top of the mounting seat 71. When the connecting rod 55 is rotated, the synchronous wheel group 57 can be used for transmission, so that the mounting seat 71 can rotate synchronously with the rotation of the connecting rod 55. At the same time, the operator can also rotate the fastening bolt 79 in the opposite direction so that the fastening bolt 79 engages with the side wall thread of the mounting seat 71 to drive the inclined block 2 78 to move to the initial position, so that the inclined block 1 77 drives the trigger block 74 to move in the direction of the initial position, so that the four contact rods 2 73 are no longer subjected to the resistance force from the surface of the trigger block 74, and the four clamping plates 72 are no longer clamped on the welding gun seat 75, so that the operator can remove the welding gun 76 separately, which can be used when welding in a narrow space.

[0054] During the rotation and switching process of the electric control turntable 51 driving the four mounting boxes 52, the storage box 83 rotates following the corresponding mounting box 52. One bevel gear in the bevel gear set 82 at the bottom end of the storage box 83 meshes with the bevel gear ring 81 at the end of the cam 62. The output end of the other bevel gear in the bevel gear set 82 drives the reciprocating lead screw 84 to rotate. The slider 85 slides outside the reciprocating lead screw 84 under the guidance of the two auxiliary rods 87. When the two elastic rods 86 are inside the storage box 83, the surface of the elastic rods 86 will be covered with antioxidant paste. By rotating the reciprocating lead screw 84, the elastic rods 86 evenly apply the antioxidant paste on the outer side of the gun head of the welding torch 76. The elastic rods 86 can closely adhere to the outer side of the gun head of the welding torch 76, effectively preventing the gun head of the welding torch 76 from being oxidized. At the same time, during the welding operation, this protective film formed by the antioxidant paste can also play a certain role in assisting heat dissipation. Part of the heat generated during welding will be absorbed and conducted by this protective film, thus avoiding the situation that the gun head of the welding torch 76 deteriorates or is damaged due to overheating.
