A welding butt joint device for electric power iron accessories

Abstract

The present invention belongs to the field of processing electric iron accessories, and specifically is an electric iron accessory welding and docking device, comprising a base and a bottom plate arranged at one end of the top of the base. The present invention extends a fixing pin into a screw hole of a connecting block, and cooperates with a pre-fixing component to drive the fixing pin to press the upper and lower inner walls of the screw hole to fix the connecting block on a support plate, so as to pre-fix the main body of the electric iron accessory. Since the fixing pin can be extended and retracted in the front of the support plate, when the thickness of the connecting block is less than the length of the fixing pin, the fixing pin will protrude from the front of the connecting block after fixing the connecting block. When the clamp drives the clamped reinforcing rib to move toward the position of the connecting block for docking, if the clamp used to clamp the reinforcing rib collides with the protruding fixing pin, the moving clamp can push the fixing pin to retract it, thereby preventing the fixing pin from causing interference, affecting the movement of the clamp, and further affecting the docking of the reinforcing rib clamped by the clamp.

Description

Technical Field

[0001] The present invention belongs to the field of processing of electric power iron accessories, and specifically relates to a welding docking device for electric power iron accessories. Background Art

[0002] Electric power iron accessories are components used in the transmission and transformation of electric power lines, and are installation accessories used on line cement poles and iron towers, including U-shaped hoop, C-shaped hoop, etc. When processing the C-shaped hoop, it is necessary to weld reinforcing ribs at the connection block positions on both sides of the C-shaped hoop to improve the structural strength of the connection between the C-shaped hoop and the connection block. Moreover, according to actual processing requirements, it is also necessary to weld components such as studs at the front of the C-shaped hoop. To ensure the accurate positions of the welded reinforcing ribs, studs and other components, it is necessary to use a docking device to ensure the precise alignment and stable connection of the electric power iron accessories during the welding process.

[0003] Some solutions have also been proposed in the prior art. For example, a patent application with the publication number CN218891405U discloses a docking device for pipe fitting welding, including a base, and docking components symmetrically arranged on the left and right of the base. The left docking component is fixed to the base by welding. This application makes the pipe fittings accurately dock by changing the docking device to automated mobile docking.

[0004] When using a docking device to fix the C-shaped hoop of electric power iron accessories, if the connection blocks on both sides of the C-shaped hoop are clamped for fixation, during the docking process of the connection block of the C-shaped hoop and the reinforcing block, the fixture pressed on the connection block may cause occlusion. This occlusion will not only affect the precise docking between the reinforcing block and the C-shaped hoop, but also further affect the subsequent welding operation.

[0005] Therefore, the present invention provides a welding docking device for electric power iron accessories. Summary of the Invention

[0006] To make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

The side support plates are located on both sides of the main body of the electric power iron accessory. A first motor is installed on the back of the casing. The rotating shaft of the first motor extends into the casing and is connected to the adjusting gear.

[0009] Preferably, there are two support plates, and the two support plates are symmetrically arranged on both sides of the midline of the top of the base plate.

[0010] Preferably, the pre-fixing component includes a rear casing fixed on the back of the support plate. A driving gear is arranged at the middle position inside the rear casing. Driven gears are engaged with the top and bottom of the driving gear. A push rack is engaged with one side of the driven gear.

A driving gear is installed at the middle position on the back of the rear casing. The rotating shaft of the driving gear extends into the rear casing and is connected to the third motor.

[0011] Preferably, the retraction component includes an internal cavity opened inside the movable block. A return spring is fixed inside the internal cavity. The front end of the return spring is fixed with a fixing pin. The fixing pin is located at the front part of the support plate.

[0012] Preferably, the size of the fixing pin matches the size of the internal cavity. The fixing pin can be telescoped at the front part of the support plate through the return spring.

[0013] Preferably, the pressing and fixing component includes a fixing groove opened at the front part of the side support plate. A pressing and fixing block is rotatably arranged inside the fixing groove. A connecting groove is opened inside the pressing and fixing block. A bracket is fixed on the top of the side support plate. A first telescopic rod is installed on the top of the bracket. The output end of the bottom of the first telescopic rod protrudes from the bottom of the bracket and is fixed with a pushing block. A second motor is installed on the top of the pushing block. A driving rod is arranged at the rotating shaft of the bottom of the second motor. The driving rod longitudinally penetrates through the inside of the side support plate and extends into the connecting groove. A driving block is fixed on the outside of the driving rod.

[0014] Preferably, the pressing and fixing blocks are evenly distributed at the front part of the side support plate. Two driving blocks are located at the bottom of the upper and lower pressing and fixing blocks. One driving block is located at the top of the pressing and fixing block at the middle position and is clamped into the connecting groove from the top of the pressing and fixing block.

[0015] Preferably, the size of the driving block matches the size of the connecting groove. When the driving block is inserted into the connecting groove, it can drive the pressing and fixing block to rotate through the driving rod.

[0016] Preferably, the second docking component includes a telescopic rod three installed at the other end of the top of the base. The output end of the telescopic rod three is equipped with a fixture two, and a connecting stud is clamped inside the fixture two. On both sides of the telescopic rod three, there are telescopic rods two. The output end of the telescopic rod two is equipped with a fixture one, and a reinforcing rib main body is clamped inside the fixture one.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. For the electric power iron accessory welding docking device described in the present invention, the fixing pin extends into the screw hole of the connecting block, and the pre-fixing component drives the fixing pin to press the upper and lower inner walls of the screw hole to fix the connecting block on the support plate, so as to perform a pre-fixing operation on the main body of the electric power iron accessory. Since the fixing pin can stretch in the front part of the support plate, when the thickness of the connecting block is less than the length of the fixing pin, after the fixing pin fixes the connecting block, it will protrude from the front part of the connecting block. When the fixture drives the clamped reinforcing rib to move towards the position of the connecting block for docking, if the fixture for clamping the reinforcing rib collides with the protruding fixing pin, the moving fixture can push the fixing pin to retract, thus preventing the fixing pin from causing interference and affecting the movement of the fixture, and further affecting the docking of the reinforcing rib clamped by the fixture.

[0019] 2. For the electric power iron accessory welding docking device described in the present invention, by the different positions of the screw holes, the pressing blocks at different positions are selected to perform a pressing and fixing operation on the connecting block, so as to prevent the pressing blocks from causing obstacles and affecting the docking of the reinforcing rib and the connecting block. And, if the pressing blocks at all positions cause obstacles, the pre-fixing component and the retracting component can be directly used to fix the main body of the electric power iron accessory, in case the use of the pressing and fixing component causes interference problems and affects the docking of the electric power iron accessory. And, when the connecting blocks on both sides of the main body of the electric power iron accessory are relatively thin, the fixing pin protrudes from the front part of the connecting block. When the pressing block presses and fixes the connecting block, if it directly presses on the fixing pin, it will first press part of the fixing pin into the built-in cavity until the pressing block is in close contact with the front part of the connecting block and the pressing and fixing is completed. The fixing pin stops retracting into the built-in cavity, and the length of the fixing pin protruding from the front part of the movable block due to the pressure is the same as the thickness of the connecting block, and it can still tightly fix the screw hole of the connecting block.

Specific embodiments

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0032] As Figures 1 to 9 shown, a welding and docking device for electric power iron accessories according to an embodiment of the present invention includes a base 1, a bottom plate 2 provided at one end of the top of the base 1, a first docking component 3 provided on the top of the bottom plate 2, and a second docking component 6 provided at the other end of the top of the base 1. A main body 5 of an electric power iron accessory is provided at the front of the first docking component 3. Pressing and fixing components 4 and pre-fixing components 7 are provided on both sides of the first docking component 3. A retraction component 8 is provided at the front end of the pre-fixing component 7.

[0033] When using the docking device to fix the C-shaped electric power iron accessory hoop, if it is fixed by clamping the connecting blocks on both sides of the C-shaped hoop, during the docking process of the connecting block and the strengthening block of the C-shaped hoop, the fixture clamped at the connecting block may cause occlusion. This occlusion will not only affect the precise docking between the strengthening block and the C-shaped hoop, but also further affect the subsequent welding operation. Therefore, during the docking of the electric power iron accessory, first use the first docking component 3 to adjust the positions of the pre-fixing component 7 and the clamping component 4, so that the positions of the pre-fixing component 7 and the clamping component 4 are adapted to the connecting blocks on both sides of the main body 5 of the electric power iron accessory. Then use the pre-fixing component 7 in cooperation with the retraction component 8 to pre-fix the screw holes of the connecting blocks on both sides of the main body 5 of the electric power iron accessory, and then cooperate with the clamping component 4 to clamp the connecting blocks on both sides of the main body 5 of the electric power iron accessory, and the fixation of the main body 5 of the electric power iron accessory can be completed. Use the second docking component 6 to clamp welding parts such as studs, and cooperate with the second docking component 6 to drive the welding parts such as studs to dock with the main body 5 of the electric power iron accessory. Finally, use welding equipment to weld the welding parts such as studs to the main body 5 of the electric power iron accessory together;

[0034] The pre-fixing component 7 and the retraction component 8 are used to fix at different positions of the screw holes on the connecting block, improving the applicability of the clamping. Cooperate with the clamping component 4 at different positions to clamp the connecting block, preventing the clamping component 4 from causing occlusion and affecting the docking of the reinforcing rib, ensuring the docking effect and the stability of the fixation at the same time. Finally, the retraction component 8 can contract into the pre-fixing component 7. When the connecting blocks on both sides of the main body 5 of the electric power iron accessory are relatively thin and the retraction component 8 protrudes from the front of the connecting block, when the clamping component 4 clamps the connecting block, it directly clamps on the retraction component 8, and will first press part of the retraction component 8 into the pre-fixing component 7 until the clamping component 4 is in close contact with the front of the connecting block, and the clamping can be completed. The shortening of the retraction component 8 not only prevents interference with the clamping component 4, but also ensures the pressing and fixation of the screw holes of the connecting block.

[0035] As Figures 1 to 4 As shown in the figure, the first docking component 3 includes a casing 31 fixed at the middle position on the top of the bottom plate 2. An adjusting gear 33 is arranged inside the casing 31. Push racks 34 are arranged at the top and bottom of the adjusting gear 33. One end of the push rack 34 is fixed with a support plate 35. The support plates 35 are located on both sides of the top of the bottom plate 2. One side of the support plate 35 is fixed with a side support plate 36. The side support plates 36 are located on both sides of the main body 5 of the electric power iron accessory. A first motor 32 is installed on the back of the casing 31. The rotating shaft of the first motor 32 extends into the casing 31 and is connected to the adjusting gear 33. There are two support plates 35, and the two support plates 35 are symmetric on both sides of the midline of the top of the bottom plate 2.

[0036] According to the different positions of the connecting blocks on both sides of the main body 5 of the electric power iron accessory, adjust the positions of the support plate 35 and the side support plate 36 to ensure that the support plate 35 and the side support plate 36 can adapt to the positions of the connecting blocks on both sides of the main body 5 of the electric power iron accessory. Start the first motor 32, the first motor 32 drives the adjusting gear 33 to rotate, the adjusting gear 33 pushes the top and bottom pushing racks 34 to move, and the pushing racks 34 drive the support plate 35 and the side support plate 36 to move away from each other, so as to expand the distance between the support plate 35 and the side support plate 36;

[0037] The first motor 32 drives the adjusting gear 33 to rotate in the reverse direction, the adjusting gear 33 pushes the top and bottom pushing racks 34 to move, the pushing racks 34 drive the support plate 35 and the side support plate 36 to move closer to each other, so as to reduce the distance between the support plate 35 and the side support plate 36. According to the different positions of the connecting blocks on both sides of the main body 5 of the electric power iron accessory, adjust the positions of the support plate 35 and the side support plate 36 to ensure that the support plate 35 and the side support plate 36 can adapt to the positions of the connecting blocks on both sides of the main body 5 of the electric power iron accessory, so as to ensure that the pre-fixing component 7, the retracting component 8 and the pressing component 4 can accurately act on the connecting blocks on both sides of the main body 5 of the electric power iron accessory for better fixing operation.

[0038] As Figure 4 、 Figure 7 、 Figure 8 and Figure 9 shown, the pre-fixing component 7 includes a rear shell 71 fixed to the back of the support plate 35. A driving gear 72 is arranged at the middle position inside the rear shell 71. The top and bottom of the driving gear 72 are engaged with driven gears 74, and one side of the driven gear 74 is engaged with a pushing rack 75. One end of the front part of the pushing rack 75 is fixed with a movable block 76, and the movable block 76 protrudes from the front part of the support plate 35. A driving gear 72 is installed at the middle position of the back of the rear shell 71, and the rotating shaft of the driving gear 72 extends into the rear shell 71 and is connected with the third motor 73.

[0039] When the screw holes of the connecting blocks on both sides of the main body 5 of the electric power iron accessory are located at the middle position, when the reinforcing ribs are welded above and below the screw holes to reinforce the main body 5 of the electric power iron accessory, the reinforcing ribs will not block the screw holes. At this time, place the connecting blocks on both sides of the main body 5 of the electric power iron accessory in front of the support plate 35, then sleeved the screw holes of the connecting blocks on the retracting component 8 at the front of the movable block 76, and make the connecting blocks closely adhere to the front of the support plate 35. Start the third motor 73, the third motor 73 drives the driving gear 72 to rotate, the driving gear 72 drives the driven gear 74 to rotate, the driven gear 74 drives the pushing rack 75 to move, and the pushing rack 75 moves the two movable blocks 76 by pushing, so that the retracting components 8 at the front of the movable blocks 76 move towards the upper and lower inner walls of the screw holes of the connecting blocks respectively until the retracting components 8 are tightly pressed against the inner walls of the screw holes of the connecting blocks, and the pre-fixing of the connecting blocks on both sides of the main body 5 of the electric power iron accessory can be completed;

[0040] When the screw holes of the connecting blocks on both sides of the main body 5 of the electric power iron accessory are located above and below, when the reinforcing rib is welded at the position between the upper and lower screw holes to reinforce the main body 5 of the electric power iron accessory, the reinforcing rib will not block the screw holes. At this time, the third motor 73 first pushes the two movable blocks 76 and the retraction assemblies 8 at the front part to move upward and downward in front of the support plate 35 respectively, so that the positions of the movable blocks 76 and the retraction assemblies 8 are aligned with the positions of the screw holes of the connecting blocks, so as to sleeve the screw holes of the connecting blocks outside the retraction assemblies 8. Sleeve the screw holes of the connecting blocks outside the retraction assemblies 8 and make the connecting blocks closely adhere to the front part of the support plate 35. Continue to start the third motor 73 to drive the movable blocks 76 and the retraction assemblies 8 in front of them to move. The retraction assembly 8 placed in the upper screw hole of the connecting block is pressed against the upper inner wall of the screw hole, and the retraction assembly 8 placed in the lower screw hole of the connecting block is pressed against the lower inner wall of the screw hole, and the pre-fixing of the connecting blocks on both sides of the main body 5 of the electric power iron accessory can be completed;

[0041] According to the different positions of the screw holes of the connecting blocks, the pre-fixing assembly 7 is used to drive the retraction assembly 8 to extend into different screw holes for pressing and fixing, so as to pre-fix the connecting blocks, improving the applicability.

[0042] As Figures 7 to 9 shown, the retraction assembly 8 includes a built-in cavity 81 opened inside the movable block 76. A return spring 82 is fixed inside the built-in cavity 81. A fixing pin 83 is fixed at the front end of the return spring 82. The fixing pin 83 is located at the front part of the support plate 35. The size of the fixing pin 83 matches the size of the built-in cavity 81. The fixing pin 83 can be telescoped at the front part of the support plate 35 through the return spring 82.

[0043] The fixing pin 83 extends into the screw hole of the connecting block, and cooperates with the pre-fixing assembly 7 to drive the fixing pin 83 to press against the upper and lower inner walls of the screw hole to fix the connecting block on the support plate 35, so as to perform the pre-fixing operation on the main body 5 of the electric power iron accessory. Since the fixing pin 83 can be telescoped at the front part of the support plate 35, when the thickness of the connecting block is less than the length of the fixing pin 83, after the fixing pin 83 fixes the connecting block, it will protrude from the front part of the connecting block. When the clamp drives the clamped reinforcing rib to move towards the position of the connecting block for docking, if the clamp for clamping the reinforcing rib touches the protruding fixing pin 83, the moving clamp can push the fixing pin 83 to retract, thus preventing the fixing pin 83 from causing interference and affecting the movement of the clamp, and further affecting the docking of the reinforcing rib clamped by the clamp.

[0044] As Figures 1 to 6As shown in the figure, the pressing and fixing component 4 includes a fixing groove 41 opened at the front of the side support plate 36. A pressing and fixing block 42 is rotatably arranged inside the fixing groove 41. A connecting groove 49 is opened inside the pressing and fixing block 42. A support 47 is fixed to the top of the side support plate 36. A first telescopic rod 48 is installed at the top of the support 47. The output end at the bottom of the first telescopic rod 48 protrudes from the bottom of the support 47 and is fixed with a pushing block 46. A second motor 45 is installed at the top of the pushing block 46. A driving rod 43 is arranged on the rotating shaft at the bottom of the second motor 45. The driving rod 43 longitudinally penetrates inside the side support plate 36 and extends into the connecting groove 49. A driving block 44 is fixed to the outside of the driving rod 43. The pressing and fixing blocks 42 are equally spaced at the front of the side support plate 36. Two driving blocks 44 are located at the bottoms of the upper and lower pressing and fixing blocks 42. One driving block 44 is located at the top of the pressing and fixing block 42 at the middle position and is clamped into the connecting groove 49 from the top of the pressing and fixing block 42. The size of the driving block 44 matches the size of the connecting groove 49. When the driving block 44 is inserted into the connecting groove 49, the pressing and fixing block 42 can be driven to rotate by the driving rod 43.

[0045] When the screw holes of the connecting blocks on both sides of the main body 5 of the electric power iron accessory are located at the middle position, when the reinforcing ribs are welded at the upper and lower positions of the screw holes to reinforce the main body 5 of the electric power iron accessory, the reinforcing ribs will not block the screw holes. At this time, select the pressing and fixing block 42 at the middle position of the front part of the side support plate 36 to press and fix the front part of the connecting block. By default, the driving block 44 at the middle position outside the driving rod 43 is clamped in the connecting groove 49 of the pressing and fixing block 42 at the middle position, and the driving rod 43 is connected to the pressing and fixing block 42 at the middle position. Start the second motor 45. The second motor 45 drives the pressing and fixing block 42 at the middle position to rotate by driving the driving rod 43. When the pressing and fixing block 42 rotates to the front end of the connecting block pre-fixed at the front of the support plate 35, the main body 5 of the electric power iron accessory can be fixed by using the pressing and fixing block 42 to press and fix the connecting block. After the docking and welding are completed, use the second motor 45 to drive the pressing and fixing block 42 to rotate in the reverse direction away from the connecting block, and the pressing and fixing operation can be stopped.

[0046] When the screw holes of the connecting blocks on both sides of the main body 5 of the electric power iron accessory are located vertically, when the reinforcing rib is welded at the position between the upper and lower screw holes to reinforce the main body 5 of the electric power iron accessory, the reinforcing rib will not block the screw holes. At this time, the pressing blocks 42 above and below the front part of the side support plate 36 are selected to press the front part of the connecting block. The first telescopic rod 48 is started to drive the pushing block 46 to move upward. The pushing block 46 drives the second motor 45 and the driving rod 43 to move upward. The driving block 44 moves out of the connecting groove 49 of the pressing block 42 at the middle position. The driving rod 43 is not connected to the pressing block 42 at the middle position. The driving blocks 44 at the bottoms of the upper and lower pressing blocks 42 move upward and are clamped into the connecting groove 49 of the pressing block 42. The driving rod 43 is connected to the upper and lower pressing blocks 42. The second motor 45 is started. The second motor 45 drives the upper and lower pressing blocks 42 to rotate. The pressing blocks 42 rotate to the front ends of the connecting blocks on the front part of the support plate 35. The main body 5 of the electric power iron accessory can be fixed by pressing the connecting block with the pressing blocks 42. After docking and welding are completed, the second motor 45 is used to drive the pressing blocks 42 to rotate in the reverse direction away from the connecting block, and the pressing operation can be stopped;

[0047] According to the different positions of the screw holes, the pressing blocks 42 at different positions are selected to perform the pressing operation on the connecting block to prevent the pressing blocks 42 from causing interference and affecting the docking of the reinforcing rib and the connecting block. Moreover, if the pressing blocks 42 at each position all cause interference, the pre-fixing assembly 7 and the retracting assembly 8 can be directly used to fix the main body 5 of the electric power iron accessory to prevent interference problems in the use of the pressing assembly 4 and affect the docking of the electric power iron accessory;

[0048] When the connecting blocks on both sides of the main body 5 of the electric power iron accessory are relatively thin, the fixing pin 83 protrudes from the front part of the connecting block. When the pressing block 42 presses the connecting block, if it is directly pressed on the fixing pin 83, the fixing pin 83 will be partially pressed into the built-in cavity 81 first until the pressing block 42 is in close contact with the front part of the connecting block and the pressing is completed. The fixing pin 83 stops retracting into the built-in cavity 81, and the length of the fixing pin 83 protruding from the front part of the movable block 76 due to the pressure is the same as the thickness of the connecting block, and it can still tightly fix the screw hole of the connecting block.

[0049] As Figure 1 And Figure 2 As shown, the second docking assembly 6 includes a third telescopic rod 64 installed at the other end of the top of the base 1. The output end of the third telescopic rod 64 is equipped with a second clamp 65. A connecting stud 66 is clamped in the second clamp 65. Both sides of the third telescopic rod 64 are provided with second telescopic rods 61. The output end of the second telescopic rod 61 is equipped with a first clamp 62. A reinforcing rib main body 63 is clamped in the first clamp 62.

[0050] Clamp the rib main body 63 with the first fixture 62, and then clamp the connecting stud 66 with the second fixture 65. Use the second telescopic rod 61 to push the first fixture 62 to drive the rib main body 63 to move towards the connecting blocks on both sides of the power iron accessory main body 5 for docking. Use the third telescopic rod 64 to push the second fixture 65 to drive the connecting stud 66 to move towards the middle position of the power iron accessory main body 5 for docking. Finally, use welding equipment to weld the rib main body 63 at the connection between the power iron accessory main body 5 and the connecting block for reinforcement, and weld the connecting stud 66 at the middle position in the front part of the power iron accessory main body 5.
