Description

Technical Field

[0001] This application relates to the field of welding machines, and more particularly to a welding machine for a compressor terminal block cover. Background Art

[0002] An air-conditioning compressor is an important part of an automotive air-conditioning refrigeration system, and it is mainly connected to an external structure through a terminal on the terminal block cover.

[0003] In the prior art, a welding machine is often used to weld and fix the terminal to the terminal block cover. The commonly used welding machine for welding terminals mainly includes a frame, on which a workbench, a hydraulic driving mechanism, and a welding mechanism are installed. Among them, the workbench and the hydraulic driving mechanism are fixedly installed on the frame, the welding mechanism is fixedly installed at the driving end of the hydraulic driving mechanism, and the hydraulic driving mechanism is erected above the workbench.

[0004] During welding processing, after an operator assembles the terminal on the terminal block cover and places the terminal block cover on the workbench, however, when the welding head on the welding mechanism contacts the terminal and the terminal block cover, the terminal is likely to shake and shift, affecting the welding effect, and there is room for improvement. Utility Model Content

[0005] In order to improve the stability of the terminal and the terminal block cover during welding and ensure the welding effect of the terminal, this application provides a welding machine for a compressor terminal block cover.

[0006] The welding machine for a compressor terminal block cover provided by this application adopts the following technical solutions:

[0007] A welding machine for a compressor terminal block cover includes a frame, on which a workbench is adjustably installed. A first fixing seat and a second fixing seat are installed on the workbench. The terminal block cover is detachably installed on the first fixing seat, and the terminal is detachably installed on the second fixing seat;

[0008] An elastic connection structure is provided between the second fixing seat and the workbench.

[0009] By adopting the above technical solution, during the actual welding process, the operator can place the terminal head on the second fixed seat in advance, and then align the seat cover with the terminal head and place it on the second fixed seat. Subsequently, the operator controls the hydraulic drive mechanism through the control button on the frame to drive the welding mechanism to move down and weld the terminal head on the seat cover, completing the welding process between the terminal head and the seat cover. By fixing the seat cover and the terminal head respectively by the first fixed seat and the second fixed seat, the displacement and shaking of the seat cover and the terminal head during the welding process can be reduced, effectively ensuring the welding effect of the welding machine. Since an elastic connection structure is provided between the first fixed seat and the workbench, support can be formed for the first fixed seat during the contact between the welding mechanism and the seat cover; when the welding is completed, the elastic connection structure can accelerate the recovery of the welding mechanism.

[0010] Preferably, the first fixing seat comprises a floating platform and a positioning seat, the floating platform is erected above the workbench, and a avoidance hole for the second fixing seat to extend out is opened on the floating platform;

[0011] The top of the floating platform is fixedly connected with two cushion blocks for adjusting the position of the seat cover, and the two cushion blocks are respectively located on both sides of the avoidance hole;

[0012] The two ends of the positioning seat are detachably mounted on the two cushion blocks respectively, and a positioning groove matched with the seat cover is formed in the positioning seat.

[0013] By adopting the above technical solution, the positioning groove can limit the position of the seat cover, reducing the occurrence of seat cover deviation and shaking during the welding process of the welding mechanism. The pad can meet the installation requirements of different seat covers according to the inclination of the bottom of the seat cover.

[0014] Preferably, the second fixing seat is fixedly mounted on the workbench, and a plurality of slots adapted to the wiring heads are formed at the end of the second fixing seat extending out of the avoidance hole.

[0015] By adopting the above technical solution, the installation and fixation of the docking terminal can be achieved through the slot on the second fixing seat.

[0016] Preferably, four connecting rods are fixedly installed on the workbench, and through holes adapted to the four connecting rods are respectively opened through the four corners of the floating platform;

[0017] The elastic connection structure comprises springs which are coaxially sleeved on the four connecting rods, and the four springs are pressed tightly between the floating platform and the workbench;

[0018] Two limiting rods are fixedly installed on the workbench. The two limiting rods are located on both sides of the second mounting seat. Two sliding holes are formed through the floating platform. Limiting blocks are fixedly connected to one ends of the two limiting rods passing through the sliding holes respectively.

[0019] By adopting the above technical solution, when the welding mechanism moves downward to weld the seat cover and the terminal, the seat cover is pressed down, making the connection between the seat cover and the terminal closer, which can improve the welding effect of the welding machine. When the welding is completed and the hydraulic driving mechanism drives the welding mechanism to move upward, the spring reset drives the floating platform to return to the initial position. While the floating platform can be automatically reset, the rising speed of the welding mechanism can be accelerated. The limiting blocks on the limiting rods can limit the highest position of the floating platform to prevent the floating platform from falling off.

[0020] Preferably, the frame includes a bottom plate. An adjusting screw rod is rotatably installed on the bottom plate. A regulator is fixedly installed on the adjusting screw rod.

[0021] An installation box is fixedly installed at the bottom of the workbench. An adjusting nut sleeve is fixedly installed at the bottom of the installation box. The top of the adjusting screw rod is threadedly connected in the adjusting nut sleeve. The regulator drives the installation box and the workbench to slide in the direction close to or away from the welding mechanism.

[0022] By adopting the above technical solution, by using the adjusting screw rod and the regulator in combination, it is convenient for the operator to adjust the height of the workbench according to the height of the seat cover.

[0023] Preferably, two guide rails are fixedly installed on the frame. Chute grooves are formed on both of the two guide rails.

[0024] A back plate is fixedly connected to the side wall of the installation box. Two sliders adapted to the chute grooves are fixedly connected to the back plate. The two sliders are embedded and slidably arranged in the two chute grooves.

[0025] By adopting the above technical solution, during the process of the installation box rising and falling driven by the adjusting screw rod, the chute grooves in the guide rails limit the sliding track of the sliders on the back plate, ensuring that the installation box and the workbench rise and fall vertically in a straight line and improving the stability of the workbench during the height adjustment process.

[0026] Preferably, a safety light curtain is fixedly installed on the frame.

[0027] By adopting the above technical solution, during the welding process of the welding machine, the safety light curtain can give an alarm when the operator accidentally reaches into the frame, ensuring the safety of the operator.

[0028] In summary, the compressor terminal seat cover welding machine of the present application has at least the following beneficial technical effects:

[0029] 1. Fixing the seat cover and the wiring head respectively through the first fixing seat and the second fixing seat can reduce the offset and shaking of the seat cover and the wiring head during the welding process, effectively ensuring the welding effect of the welding machine;

[0030] 2. When the welding is completed and the hydraulic drive mechanism drives the welding mechanism to move upward, the spring reset drives the floating platform to return to the initial position, which can not only make the floating platform automatically reset, but also accelerate the rise of the welding mechanism;

[0031] 3. By using the adjusting screw and the adjuster in combination, it is convenient for the operator to adjust the height of the workbench according to the height of the seat cover. Brief Description of the Drawings

Detailed Description of the Embodiment

[0036] The following further elaborates on the present application in conjunction with the attached Figures 1-3 drawings.

[0037] Embodiment

[0038] The embodiment of the present application discloses a welding machine for a compressor wiring seat cover. Referring to Figure 1 , it includes a frame 1, on which a workbench 2 is adjustably installed. A first fixing seat 3 and a second fixing seat 4 are installed on the workbench 2. The seat cover 5 is detachably installed on the first fixing seat 3, and the wiring head 6 is detachably installed on the second fixing seat 4; an elastic connection structure 7 is provided between the second fixing seat 4 and the workbench 2.

[0039] During the actual welding process, the operator can place the terminal head 6 on the second fixing seat 4 in advance, and then align the seat cover 5 with the terminal head 6 and place it on the second fixing seat 4. Subsequently, the operator controls the hydraulic drive mechanism through the control button on the frame 1 to drive the welding mechanism 8 to move downward to weld the terminal head 6 on the seat cover 5, thereby completing the welding process between the terminal head 6 and the seat cover 5. By fixing the seat cover 5 and the terminal head 6 respectively by the first fixing seat 3 and the second fixing seat 4, the occurrence of displacement and shaking of the seat cover 5 and the terminal head 6 during the welding process can be reduced, and the welding effect of the welding machine can be effectively guaranteed.

[0040] Since an elastic connection structure 7 is provided between the first fixing seat 3 and the workbench 2, the first fixing seat 3 can be supported during the contact between the welding mechanism 8 and the seat cover 5; when welding is completed, the elastic connection structure 7 can accelerate the recovery of the welding mechanism 8.

[0041] Reference Figure 1 , Figure 2 as well as Figure 3 The first fixed seat 3 includes a floating platform 31 and a positioning seat 32. The floating platform 31 is erected above the workbench 2, and an avoidance hole 33 is opened on the floating platform 31 for the second fixed seat 4 to extend out; two pads 34 for adjusting the position of the seat cover 5 are fixedly connected to the top of the floating platform 31, and the two pads 34 are respectively located on both sides of the avoidance hole 33; the two ends of the positioning seat 32 are respectively detachably mounted on the two pads 34, and a positioning groove 321 adapted to the seat cover 5 is formed in the positioning seat 32.

[0042] The positioning groove 321 can limit the position of the seat cover 5, reducing the occurrence of deviation and shaking of the seat cover 5 during the welding process of the welding mechanism 8. The cushion block 34 can meet different installation requirements of the seat cover 5 according to the inclination of the bottom of the seat cover 5.

[0043] Reference Figure 2 and Figure 3 The second fixing seat 4 is fixedly mounted on the workbench 2, and the end of the second fixing seat 4 extending out of the avoidance hole 33 is provided with a plurality of slots 41 adapted to the wiring head 6. Through the slots 41 on the second fixing seat 4, the installation and fixation of the wiring head 6 can be realized.

[0044] Reference Figure 1 and Figure 2, four connecting rods 21 are fixedly installed on the workbench 2, and through holes adapted to the four connecting rods 21 are respectively formed through the four corners of the floating platform 31; the elastic connection structure 7 includes springs 71 coaxially sleeved on the connecting rods 21, and the four springs 71 are all abutted between the floating platform 31 and the workbench 2; two limiting rods 22 are fixedly installed on the workbench 2, the two limiting rods 22 are located on both sides of the second mounting seat, two sliding holes are formed through the floating platform 31, and limiting blocks 23 are respectively fixedly connected to one ends of the two limiting rods 22 passing through the sliding holes.

[0045] When the welding mechanism 8 moves downward to weld the seat cover 5 and the terminal 6, the seat cover 5 is pressed down, making the connection between the seat cover 5 and the terminal 6 tighter, which can improve the welding effect of the welding machine. When the welding is completed and the hydraulic drive mechanism drives the welding mechanism 8 to move upward, the spring 71 resets to drive the floating platform 31 to return to the initial position. While the floating platform 31 can be automatically reset, the rising speed of the welding mechanism 8 can be accelerated. The limiting blocks 23 on the limiting rods 22 can limit the highest position of the floating platform 31 to prevent the floating platform 31 from falling off.

[0046] Refer to Figure 2 , the frame 1 includes a bottom plate 11, an adjusting screw 12 is rotatably installed on the bottom plate 11, and a regulator 13 is fixedly installed on the adjusting screw 12; an installation box 24 is fixedly installed at the bottom of the workbench 2, an adjusting nut sleeve 14 is fixedly installed at the bottom of the installation box 24, and the top of the adjusting screw 12 is threadedly connected into the adjusting nut sleeve 14, and the regulator 13 drives the installation box 24 and the workbench 2 to slide in a direction close to or away from the welding mechanism 8.

[0047] By using the adjusting screw 12 and the regulator 13 in combination, it is convenient for the operator to adjust the height of the workbench 2 according to the height of the seat cover 5.

[0048] Refer to Figure 2 , two guide rails 15 are fixedly installed on the frame 1, and sliding grooves 151 are formed in both of the two guide rails 15. And a back plate 25 is fixedly connected to the side wall of the installation box 24, and two sliders adapted to the sliding grooves 151 are fixedly connected to the back plate 25, and the two sliders are embedded and slidably arranged in the two sliding grooves 151.

[0049] During the process of the installation box 24 being driven by the adjusting screw 12 to move up and down, the sliding grooves 151 in the guide rails 15 limit the sliding tracks of the sliders on the back plate 25, ensuring that the installation box 24 and the workbench 2 move up and down in a straight line, and improving the stability of the workbench 2 during the height adjustment process.

[0050] Referring to the figure, a safety grating 16 is fixedly mounted on the frame 1. The safety grating 16 includes a transmitting end and a receiving end, and the transmitting end and the receiving end are fixedly mounted on the frame 1 by screws, and the transmitting end and the receiving end are located in front of the workbench 2.

[0051] During the welding process of the welding machine, the safety grating 16 can sound an alarm when the operator reaches into the frame 1 by mistake, thereby ensuring the safety of the operator.

[0052] The implementation principle of a compressor terminal seat cover welding machine in the embodiment of the present application is as follows: during the actual welding process, the operator can place the terminal head 6 on the second fixed seat 4 in advance, and then align the seat cover 5 with the terminal head 6 and place it on the second fixed seat 4. Subsequently, the operator controls the hydraulic drive mechanism through the control button on the frame 1 to drive the welding mechanism 8 to move down and weld the terminal head 6 to the seat cover 5, thereby completing the welding process between the terminal head 6 and the seat cover 5. By fixing the seat cover 5 and the terminal head 6 respectively by the first fixed seat 3 and the second fixed seat 4, the occurrence of displacement and shaking of the seat cover 5 and the terminal head 6 during the welding process can be reduced, and the welding effect of the welding machine can be effectively guaranteed. Since an elastic connection structure 7 is provided between the first fixed seat 3 and the workbench 2, support can be formed for the first fixed seat 3 during the contact between the welding mechanism 8 and the seat cover 5; when the welding is completed, the elastic connection structure 7 can accelerate the recovery of the welding mechanism 8.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
