Description
Technical Field
[0001] This application relates to the field of automotive air conditioning parts processing technology, specifically a metal pipe welding device. Background Technology
[0002] Automotive air conditioning systems generally consist of a compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, piping, condenser fan, vacuum solenoid valve, idle speed control, and a control system. The evaporator's function is to evaporate the low-pressure refrigerant from the expansion valve, absorbing heat from the air inside the vehicle, thus cooling the cabin. Evaporators come in three types: tube-plate, tube-strip, and laminated. Currently, most passenger cars in my country use the all-aluminum laminated type. The evaporator installed inside the car is connected to the vehicle's internal piping using metal pipes. During the evaporator manufacturing process, a pipe joint is welded to one side, and then one end is directly fixed to the expansion valve.
[0003] Existing assembly and welding equipment uses tooling to assemble and fix pipe joints and evaporators, and then a movable welding nozzle is set on one side of the tooling, so that the flame of the welding nozzle can move to weld the welding part. However, when welding using tooling assembly, the tooling needs to be cooled down before the next evaporator and pipe joint can be assembled. This method has low welding efficiency and is not conducive to continuous production.
[0004] Therefore, it is necessary to provide a metal pipe welding device to solve the above problems.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content
[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a metal pipe welding device that solves the problem of low welding efficiency caused by the existing assembly method.
[0007] The technical solution adopted by this application to solve its technical problem is: a metal pipe welding device, including a stand and a workbench; a moving component is provided on the top of the stand, a feeding component is provided at the bottom of the moving component, and the workbench is located below the feeding component; a clamping component for fixing an evaporator is provided on the top of the workbench.
[0008] The feeding assembly includes a support column; a connecting seat is fixedly sleeved on the central section of the support column, and the top of the connecting seat away from the support column is fixedly connected to the bottom of the mounting base; two sliding seats are movably sleeved on the shaft of the support column, and the connecting seat is located between the two sliding seats; a support arm is fixedly installed on the bottom of the sliding seat away from the connecting seat, and the support arm and the support column are perpendicularly intersected through the sliding seats; electrically controlled grippers are fixedly sleeved on both ends of the support arm; the sliding seat is located between the two electrically controlled grippers; thus, the electrically controlled grippers on the same side of the two support arms cooperate to clamp a pipe joint, and the moving assembly controls the feeding assembly to move laterally to the clamping assembly, so that the pipe joint is connected to the evaporator; then the operator places the welding material at the connection point, controls the welding nozzle to move laterally, and heats the connection point to achieve welding; in addition, when the electrically controlled gripper on one side of the connecting seat is clamping the pipe joint for welding, the electrically controlled gripper on the other side performs the feeding action, thereby shortening the welding time.
[0009] Furthermore, the electrically controlled grippers are arranged vertically downwards, and the electrically controlled grippers on the same side of the support arm are arranged in parallel.
[0010] Furthermore, the two ends of the support column are provided with helical grooves, and the interior of the sliding seat is provided with a ball screw pair, which is a mating structure with the helical grooves; thus, the two sliding seats move on the support column, thereby adjusting the distance between the two electrically controlled grippers acting on the same pipe joint; the ball screw pair inside the sliding seat uses steel balls as rolling elements to convert torque into axial repetitive force, enabling the sliding seat to move flexibly on the support column, while improving the problems of poor positioning and easy damage caused by sliding friction.
[0011] Furthermore, the moving component includes a slide table and an electric actuator; a slide rail is provided on the top of the upright, the bottom of the slide table is slidably engaged with the slide rail, the movable part of the electric actuator is fixedly connected to one side of the slide table, and the fixed part of the electric actuator is fixedly connected to the top of the upright; thus, the electric actuator controls the slide table to move in the horizontal direction, thereby realizing the moving component driving the feeding component to move.
[0012] Furthermore, the moving assembly also includes an electric push rod II and a mounting base. The fixed part of the electric push rod II is mounted on the top of the slide table, and the movable part of the electric push rod II faces downward. A connecting column is provided on the top of the mounting base, and the movable part of the electric push rod II is fixedly connected to the connecting column. Thus, the slide table moves the mounting base through the electric push rod II, and the electric push rod II can adjust the height of the mounting base as needed, making it easy for the feeding assembly to adapt to different models of evaporators.
[0013] Furthermore, a slide rod is fixedly installed on the top of the mounting base, and the end of the slide rod away from the mounting base slides in cooperation with the slide table.
[0014] Furthermore, the clamping assembly includes a support frame one and a support frame two. The bottom of the support frame one is fixedly mounted on the workbench, and a slide rail two is provided on the top of the workbench. The slide rail two is located on one side of the support frame one, and the bottom of the support frame two slides in cooperation with the slide rail two. Thus, the distance between the support frame two and the support frame one can be adjusted in real time according to the thickness of the evaporator.
[0015] Furthermore, an electric actuator three is fixedly installed on the top of the workbench. The electric actuator three is located between the slide rails two, and the movable part of the electric actuator three is fixedly connected to the support frame two. Thus, the electric actuator three replaces manual adjustment, saving time and effort.
[0016] The beneficial effects of this application are as follows: The metal pipe welding device provided by this application is equipped with a feeding component. The electrically controlled grippers on the same side of the two support arms cooperate to clamp a pipe joint. The moving component controls the feeding component to move laterally to the clamping component, so that the pipe joint is connected to the evaporator. Then, the operator places the welding material at the connection point and controls the welding nozzle to move laterally to heat the connection point, thereby achieving welding. In addition, when the electrically controlled gripper on one side of the connecting seat is clamping the pipe joint for welding, the electrically controlled gripper on the other side performs the feeding action, thereby shortening the welding time.

[0026] like Figures 1-2 As shown, this application provides a metal pipe welding device, including a stand 11 and a worktable 12; a moving component is provided on the top of the stand 11, a feeding component 3 is provided at the bottom of the moving component, and the worktable 12 is located below the feeding component 3; a clamping component for fixing an evaporator 5 is provided on the top of the worktable 12.
[0027] Reference Figure 2 The feeding assembly 3 includes a support column 31; a connecting seat 32 is fixedly sleeved on the central section of the support column 31, and the top of the connecting seat 32 away from the support column 31 is fixedly connected to the bottom of the mounting base 24; two sliding seats 33 are movably sleeved on the shaft of the support column 31, and the connecting seat 32 is located between the two sliding seats 33; a support arm 34 is fixedly installed on the bottom of the sliding seat 33 away from the connecting seat 32, and the support arm 34 and the support column 31 are perpendicularly intersected through the sliding seat 33; electrically controlled grippers 35 are fixedly sleeved on both ends of the support arm 34; the sliding seats 33 are located between the two... Between the two electrically controlled grippers 35, the electrically controlled grippers 35 on the same side of the two support arms 34 cooperate to clamp a pipe joint. The moving component controls the feeding component 3 to move laterally to the clamping component, so that the pipe joint is connected to the evaporator 5. Then the worker places the welding material at the connection point, controls the welding nozzle to move laterally, and moves to heat the connection point to achieve welding. In addition, when the electrically controlled gripper 35 on one side of the connecting seat 32 clamps the pipe joint for welding, the electrically controlled gripper 35 on the other side performs the feeding action, thereby shortening the welding time.
[0028] Among them, the electrically controlled gripper 35 is set vertically downward, and the electrically controlled gripper 35 on the same side of the support arm 34 is set in parallel.
[0029] The support column 31 has helical grooves at both ends of its shaft, and the sliding seat 33 has a ball screw pair inside, which is a mating structure with the helical grooves. Thus, the two sliding seats 33 move on the support column 31, thereby adjusting the distance between the two electrically controlled grippers 35 acting on the same pipe joint. The ball screw pair inside the sliding seat 33 uses steel balls as rolling elements to convert torque into axial repetitive force, enabling the sliding seat 33 to move flexibly on the support column 31, while improving the problems of poor positioning and easy damage caused by sliding friction.

The movable part of the electric push rod 22 is fixedly connected to one side of the slide table 21, and the fixed part of the electric push rod 23 is fixedly connected to the top of the upright frame 11. Thus, the electric push rod 22 controls the slide table 21 to move in the horizontal direction, thereby enabling the moving component to drive the feeding component 3 to move.
[0031] The moving assembly also includes an electric push rod 23 and a mounting base 24.

A connecting column is provided on the top of the mounting base 24, and the movable part of the electric push rod 23 is fixedly connected to the connecting column. Thus, the slide table 21 drives the mounting base 24 to move through the electric push rod 23. At the same time, the electric push rod 23 can adjust the height of the mounting base 24 as needed, so that the feeding assembly 3 can be adapted to different models of evaporators 5.
[0032] A slide rod 241 is fixedly installed on the top of the mounting base 24, and the end of the slide rod 241 away from the mounting base 24 slides in engagement with the slide table 21.

The top of the worktable 12 is provided with a second slide rail, which is located on one side of the first support frame 41. The bottom of the second support frame 42 slides in cooperation with the second slide rail. Thus, the distance between the second support frame 42 and the first support frame 41 can be adjusted in real time according to the thickness of the evaporator 5.
[0034] In addition, an electric actuator three is fixedly installed on the top of the workbench 12.
