Description

Technical Field

[0001] The invention relates to the field of welding equipment, in particular to automatic welding equipment for monitoring vertical pole production. Background Art

[0002] Monitoring poles are important supporting structures for installing road monitoring equipment, traffic lights and other facilities. The bottom of the pole usually requires a welded flange to achieve a fixed connection with the base. The main body of the pole is mainly divided into two types: hexagonal pole and cylindrical pole according to different application scenarios, and the flange is designed to be square or round according to the connection requirements.

[0003] At present, the welding of the monitoring pole and the flange is mainly completed by a horizontal fixture in combination with an automated welding gun. Specifically, the horizontal fixture uses the conical blocks at both ends to center the flange and the pole, and then the welding gun is driven by the electric cylinder to move to the contact position between the flange and the pole. During welding, the fixture drives the pole and the flange to rotate synchronously, and the welding gun completes the welding along the circumferential seam trajectory.

[0004] However, the above welding method has the following significant problems: First, the welding slag generated during the welding process can easily splash onto the contact surface of the conical block and the flange, causing the two to stick together, affecting the reuse accuracy of the fixture and the efficiency of equipment maintenance; second, due to the large difference in cross-section between the hexagonal rod and the cylindrical rod, and the different positioning methods of the square flange and the circular flange, the clamping structure of the existing equipment is difficult to be compatible with multiple combinations, requiring frequent replacement of the fixture or adjustment of parameters, resulting in reduced production efficiency.

The alignment component includes a plurality of abutment columns arranged for left and right sliding. The alignment component is provided with three circumferentially evenly distributed inner support plates through an adjustment component. The adjustment component is used to adjust the position of the inner support plate so that the inner support plate supports the round rod and the hexagonal rod.

[0008] The protective mechanism includes a blocking block arranged on the alignment component and a guide column arranged on the left side of the fixed bracket for sliding left and right. During welding, as the vertical pole rotates, the guide column can gradually reduce the number of abutment columns against the side of the flange, thereby preventing adhesion.

[0009] Preferably, the alignment assembly includes four movable sleeves that are evenly spaced along the circumference of the guide post and slide radially along the guide post, and a side of the movable sleeve close to the inner support plate is slidably provided with an abutting square rod.

[0010] Preferably, the blocking block has a hollow structure, and is fixedly connected to the lower side of the upper abutting square rod.

The pushing plate frame is connected to the movable sleeve at the corresponding position for left and right sliding, and a track groove is provided on the pushing plate frame for driving the movement of the square rod.

[0013] Preferably, a telescopic rod is fixedly installed on the right side of the movable sleeve, a feed block is fixedly installed on the telescopic section of the telescopic rod, a disc plate is rotatably provided on the left side of the guide column, the abutment column is arranged along the circumference of the disc plate and slides left and right on the disc plate, an axis kit is fixedly installed inside the disc plate, an end face threaded disk is rotatably provided on the right side of the axis kit, and the end face threaded disk is threadedly connected to all the feed blocks.

[0014] Preferably, the adjustment assembly includes a threaded rod that is slidably arranged on the inner side of the shaft sleeve. The left side of the threaded rod and the left side of the shaft sleeve are both hinged with connecting plates at equal intervals along the circumference of the guide column, and the connecting plates at two corresponding positions are hinged at the same position on the inner support plate.

[0015] Preferably, a rotating disk is rotatably provided on the right side of the end face threaded disk, which is threadedly connected to the threaded rod.

[0016] Preferably, the tightening assembly includes a one-way screw threadedly connected to the vertical section on the left side of the frame, and a cone head block is rotatably provided at the right end of the one-way screw.

[0017] The beneficial effects of the present invention are: 1. The present invention adopts three circumferentially evenly distributed inner support plates controlled by the alignment component and the adjustment component, which can adapt to the cross-sectional differences between the hexagonal rod and the cylindrical rod, thereby quickly positioning and clamping the hexagonal rod and the cylindrical rod, and through the alignment component, it can also be compatible with the positioning requirements of square and circular flanges, significantly improving the versatility of welding equipment and avoiding frequent replacement of fixtures.

[0018] 2. The present invention adjusts and connects the rotating disk and the end threaded disk. The operator only needs to rotate the rotating disk to control the movement of the inner support plate and the movable sleeve, thereby synchronously clamping the vertical rod and the flange, further simplifying the operation. By adjusting the relative angle between the rotating disk and the end threaded disk, it can adapt to vertical rods and flanges of different diameters.

[0019] 3. The present invention adopts the coordinated effect of the abutment column and the tightening component in the alignment component, and drives the abutment column to automatically stop supporting the outer side of the flange by pushing the flange through the vertical rod, thereby achieving precise alignment of the flange and the vertical rod while preventing welding slag from splashing between the alignment component and the flange. At the same time, the number of abutment columns and flanges that fit together can be gradually reduced during welding, further effectively preventing welding slag from splashing to the contact surface during welding, and solving the adhesion problem.

[0020] 4. The present invention adopts a blocking block to block the welding position, preventing the splashing welding slag from falling over the upper part of the flange to the contact position between the abutment column and the flange, further preventing adhesion, and the blocking block can also collect the splashing welding slag into the drawer box through the internal buffer plate and the reflective block, preventing the welding slag from adhering randomly and affecting the welding quality.

DETAILED DESCRIPTION

[0031] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0032] See Figure 1 and Figure 2 A monitoring pole production automatic welding equipment includes a frame 1 and a welding gun 2. The frame 1 is a U-shaped structure. The frame 1 is provided with a limiting mechanism 3 for clamping the round rod and the hexagonal rod by pressing the two ends together, and a protective mechanism 4 for preventing the flange and the limiting mechanism 3 from sticking together during welding.

[0033] When it is necessary to weld the upright pole and the flange, the flange and the upright pole are first synchronously aligned and fixed by the limiting mechanism 3. Then the limiting mechanism 3 rotates the upright pole and the flange, and the welding gun 2 is used to perform circumferential welding on the joint of the upright pole and the flange. During welding, the protective mechanism 4 can prevent welding slag from splashing to the contact position between the limiting mechanism 3 and the flange, thereby avoiding the limiting mechanism 3 and the flange from sticking together.

[0034] See Figure 1 、 Figure 2 and Figure 3The limiting mechanism 3 includes a fixed bracket 31 arranged on the left side of the vertical section on the right side of the frame 1. The fixed bracket 31 is provided with a positioning component 32 for aligning the square and circular flanges by a surrounding support method. The positioning component 32 includes a plurality of abutment columns 321 arranged for sliding left and right. The positioning component 32 is provided with three circumferentially evenly distributed inner support plates 34 through an adjustment component 33. The adjustment component 33 is used to adjust the position of the inner support plate 34 so that the inner support plate 34 supports the round rod and the hexagonal rod. A tightening component 35 for pushing the vertical rod is provided on the left side of the frame 1.

[0035] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The protective mechanism 4 includes a blocking block 41 arranged on the alignment component 32, and a guide column 42 arranged on the left side of the fixed bracket 31 for sliding left and right. A coil spring is arranged between the guide column 42 and the fixed bracket 31. During welding, as the vertical pole rotates, the guide column 42 can gradually reduce the number of abutting columns 321 against the side of the flange, thereby preventing adhesion.

[0036] See Figure 1 The tightening assembly 35 includes a one-way screw 351 threadedly connected to the vertical section on the left side of the frame 1. The right end of the one-way screw 351 is rotatably provided with a cone head block 352, and the cone head block 352 is coaxially arranged with the guide column 42.

[0037] See Figure 2 、 Figure 3 、 Figure 4 and Figure 5 A disc plate 36 is rotatably provided on the left side of the guide column 42, and the abutment column 321 is arranged along the circumference of the disc plate 36 and slides left and right on the disc plate 36. A shaft kit 361 is fixedly installed inside the disc plate 36, and the adjustment component 33 includes a threaded rod 331 that is slidably provided on the inside of the shaft kit 361. The left side of the threaded rod 331 and the left side of the shaft kit 361 are hinged with three connecting plates 332 at equal intervals along the circumference of the guide column 42, and the connecting plates 332 at two corresponding positions are hinged to the same position on the inner support plate 34.

[0038] When the flange needs to be welded to the vertical pole, the operator manually puts the flange on the outside of the shaft sleeve 361, and at the same time makes the right side of the flange fit against the left side of the abutment column 321. The operator then puts the right side of the vertical pole on the outside of the threaded rod 331, which makes the vertical pole cover the outside of all the inner support plates 34. The operator then puts the left side of the vertical pole on the cone head block 352, so that the cone head block 352 is inserted into the interior of the vertical pole. The cone head block 352 adaptively aligns the right side of the vertical pole through its characteristic of gradually increasing diameter from right to left.

[0039] See Figure 2 、 Figure 3 and Figure 6 The alignment component 32 includes four movable sleeves 322 that are evenly spaced along the circumference of the guide column 42 on the fixed bracket 31 and slide radially along the guide column 42. The movable sleeve 322 is provided with a square rod 323 that slides against the side close to the inner support plate 34.

[0040] See Figure 3 and Figure 6 A linkage plate 324 is fixedly installed on the outer side of the guide column 42 at equal intervals along its circumference. A pushing plate frame 325 is provided on the left side of the linkage plate 324 for radial sliding along the guide column 42. The pushing plate frame 325 is connected to the movable sleeve 322 at the corresponding position for left and right sliding. A track groove is provided on the pushing plate frame 325 for driving the movement of the square rod 323.

[0041] In this embodiment, the right part of the track groove is a horizontal straight structure, and the left part of the track groove is an inclined groove structure that gradually tilts from right to left in the direction away from the guide column 42. A linkage rod is fixedly installed on the square rod 323, and the linkage rod is slidably connected to the inside of the corresponding track groove.

[0042] In the initial state, the linkage rod is located at the right end position of the linear structure corresponding to the track groove, so that the end of the square rod 323 close to the guide column 42 is at a position extending outside the movable sleeve 322.

[0043] See Figure 3 、 Figure 6 and Figure 7 The blocking block 41 has a hollow structure and is fixedly connected to the lower side of the upper abutting square rod 323. An opening is provided on the left side of the blocking block 41. A drawer box 411 is provided on the lower side of the blocking block 41 for sliding back and forth, and a buckle 412 is provided on the front side of the blocking block 41 for sliding up and down.

[0044] It should be noted that the height of the upper abutting square rod 323 is smaller than that of the other three abutting square rods 323 , and the total height of the upper abutting square rod 323 , the blocking block 41 and the drawer box 411 is equal to the height of the other three abutting square rods 323 .

[0045] See Figure 3 、 Figure 4 and Figure 6 A telescopic rod 326 is fixedly installed on the right side of the movable sleeve 322, and a feed block 327 is fixedly installed on the telescopic section of the telescopic rod 326. An end threaded disk 362 is rotatably provided on the right side of the shaft kit 361, and the end threaded disk 362 is threadedly connected to all the feed blocks 327.

[0046] See Figure 3 、 Figure 4 and Figure 5A rotating disk 333 is rotatably provided on the right side of the end face threaded disk 362, and the rotating disk 333 is threadedly connected to the threaded rod 331. A number of positioning holes are opened on the right side of the end face threaded disk 362 at equal intervals along its circumference, and a positioning screw 334 is spirally connected to the rotating disk 333 for inserting into the positioning hole.

[0047] When the right side of the flange is in contact with the left side of the abutment column 321, the flange is located between the four abutment square rods 323. When the vertical rod is simultaneously sleeved on the outside of the inner support plate 34 and the cone head block 352, the operator manually rotates the one-way screw 351 so that the one-way screw 351 pushes the vertical rod to the right through the cone head block 352, so that the right side of the vertical rod is in contact with the left side of the flange.

[0048] The operator then manually rotates the rotating disk 333, which drives the threaded rod 331 to move to the right. The threaded rod 331 synchronously pushes the three inner support plates 34 in the direction away from the axis of the threaded rod 331 through the connecting plate 332, so that the inner support plates 34 rest against the inner side surface of the vertical pole, thereby centering and clamping the vertical pole, and then the vertical pole and the guide column 42 are arranged coaxially.

[0049] It should be noted that when the vertical pole is a cylindrical pole, the inner support plate 34 is in linear contact with the inner side surface of the cylindrical pole. When the vertical pole is a hexagonal pole, the inner support plate 34 is in surface contact with the inner side surface of the hexagonal pole, so that the inner support plate 34 can center and clamp both vertical poles to ensure the stability of the alignment.

[0050] When the rotating disk 333 rotates, the end threaded disk 362 is driven to rotate synchronously through the positioning screw 334. The end threaded disk 362 drives the movable sleeve 322 to move toward the flange through the feed block 327 and the telescopic rod 326, so that when the inner support plate 34 is pressed against the vertical pole, the front, lower and rear movable sleeves 322 drive the abutting square rod 323 to press against the outer surface of the flange, and the upper abutting square rod 323 drives the drawer box 411 to press against the outer surface of the flange through the blocking block 41, and at the same time pushes the flange to the coaxial position of the guide column 42, so that the flange and the vertical pole are coaxially aligned.

[0051] It should be noted that when the flange is square, the abutting square rod 323 and the drawer box 411 abut against the four sides of the square flange respectively, thereby positioning the square flange.

[0052] When it is necessary to position the vertical poles and flanges of different diameters, the operator manually rotates the positioning screw 334 to make the positioning screw 334 withdraw from the positioning hole, so that the end threaded disk 362 and the rotating disk 333 can rotate freely respectively. The operator then rotates the end threaded disk 362 and the rotating disk 333 respectively, so that the flange and the vertical pole are respectively centered and clamped. Then the operator rotates the positioning screw 334 to lock the end threaded disk 362 and the rotating disk 333 together, so that the rotating disk 333 can simultaneously align the flange and the vertical pole.

[0053] It should be noted that if Figure 4 and Figure 6 As shown, a cross plate 363 is rotatably provided on the right side of the shaft kit 361, and the cross plate 363 is slidably connected to the feed block 327. The cross plate 363 is slidably connected to the fixed bracket 31 left and right, so that the cross plate 363 drives the feed block 327 to always be spirally connected to the end face threaded disk 362, and the cross plate 363 prevents the feed block 327 from rotating with the end face threaded disk 362.

[0054] See Figure 4 、 Figure 5 and Figure 6 A guide groove 421 is provided on the outside of the guide column 42. The left and right parts of the guide groove 421 are both C-shaped structures. The middle part of the guide groove 421 is a spiral structure that connects the two C-shaped structures. The abutment column 321 is slidably connected to the guide groove 421 through the raised column thereon.

[0055] It should be noted that, in the initial state, all the raised columns on the abutment column 321 are located inside the C-shaped structure on the left side of the guide groove 421, so that the raised columns of the abutment column 321 are blocked by the end of the C-shaped structure on the left side of the guide groove 421, preventing the upper part of the disc plate 36 from rotating forward. The disc plate 36 prevents the threaded rod 331 from rotating with the rotating disk 333 through the shaft kit 361, so that the rotating disk 333 is threadedly engaged with the threaded rod 331.

[0056] When the flange and the vertical rod are clamped and positioned, the operator manually turns the one-way screw 351 so that the cone head block 352 pushes the vertical rod to continue to move to the right, and the vertical rod drives the flange to move synchronously. The flange pushes the guide column 42 through the abutment column 321, so that the guide column 42 compresses the coil spring, and the guide column 42 drives the pushing plate frame 325 to move synchronously through the linkage plate 324, so that the pushing plate frame 325 pushes the abutment square rod 323 through the oblique groove part of the track groove thereon in the direction away from the vertical rod, so that the abutment square rod 323 and the drawer box 411 no longer contact the flange. At this time, the coil spring pushes the flange to always abut against the vertical rod through its own elastic force to prevent the flange position from changing. Then the vertical rod pushes the guide column 42 to abut against the fixed bracket 31, so that the vertical rod abuts the flange.

[0057] It should be noted that an L-shaped plate is provided on the left side of the frame 1 for sliding left and right. The vertical section of the L-shaped plate is rotatably connected to the one-way screw 351. The upper side of the L-shaped plate is fixedly installed with a driving motor that is connected to the cone head block 352 for rotation through a belt. The welding gun 2 is connected to the frame 1 through an existing adjustable position support.

[0058] When the vertical pole is pressed against the flange, move the welding gun 2 to the contact position between the vertical pole and the flange, start the welding gun 2 to weld the vertical pole and the flange, and at the same time start the driving motor to drive the vertical pole and the flange to rotate through the cone head block 352, so that the welding gun 2 performs circumferential welding on the vertical pole and the flange.

[0059] At the same time, the vertical rod and the flange drive the upper part of the disc plate 36 to rotate backward, so that the disc plate 36 drives the abutment column 321 to rotate synchronously, and the abutment column 321 moves along the trajectory of the guide groove 421 through the raised column thereon, so that the abutment column 321 that rotates backward and corresponds to the position where the welding between the vertical rod and the flange is completed moves to the right along the trajectory of the guide groove 421, so that the corresponding abutment column 321 no longer contacts the position of the flange welding completion area, thereby reducing the possibility of welding slag splashing onto the abutment column 321 and the flange and causing adhesion.

[0060] See Figure 7 and Figure 8 A buffer plate 413 is provided inside the blocking block 41 for sliding left and right, a buffer spring is provided between the buffer plate 413 and the blocking block 41, and a reflective block 414 is fixedly installed on the left side of the buffer plate 413 at equal intervals in the vertical direction.

[0061] During welding, the blocking block 41 blocks above the flange to prevent the welding slag from passing over the flange. When the welding slag splashes into the inside of the blocking block 41, the welding slag contacts the buffer plate 413 or the inclined surface of the reflecting block 414. The buffer plate 413 is elastically connected to the buffer spring, so that the buffer plate 413 slows down the splashing welding slag. At the same time, the welding slag is guided to fall into the inside of the drawer box 411 through the rebound of the reflecting block 414, so as to collect the welding slag, reduce the occurrence of welding slag adhering to the flange or the vertical pole, improve the welding quality, and the welding slag can be centrally processed by pulling out and cleaning the drawer box 411.

[0062] See Figures 1 to 8 When welding the vertical pole and the flange, the present invention also includes the following steps: In the first step, the operator manually puts the flange on the outside of the shaft sleeve 361, and at the same time makes the right side of the flange fit against the left side of the abutment column 321. Then the operator puts the right side of the vertical pole on the outside of the threaded rod 331, and puts the left side of the vertical pole on the cone head block 352.

[0063] In the second step, the operator manually rotates the rotating disk 333 so that the inner support plate 34 rests on the inner side of the vertical pole. The rotating disk 333 rests against the square rod 323 and the drawer box 411 through the end threaded disk 362 to tighten the flange, so that the flange is coaxially aligned with the vertical pole.

[0064] In the third step, the operator manually rotates the one-way screw 351, so that the cone head block 352 pushes the vertical rod to continue to move to the left, so that the guide column 42 drives the square rod 323 and the drawer box 411 to no longer contact the flange. At the same time, the vertical rod pushes the guide column 42 to press against the fixed bracket 31, so that the vertical rod presses against the flange.

[0065] The fourth step is to move the welding gun 2 to the contact position between the vertical pole and the flange, start the welding gun 2 to weld the vertical pole and the flange, and at the same time start the driving motor to drive the vertical pole and the flange to rotate through the cone head block 352, so that the welding gun 2 performs circumferential welding on the vertical pole and the flange.

[0066] In the fifth step, the abutment column 321 corresponding to the position where the welding of the vertical pole and the flange is completed rotates backward and moves to the right along the trajectory of the guide groove 421, so that the abutment column 321 does not contact the position of the flange welding completion area, thereby reducing the possibility of welding slag splashing onto the abutment column 321 and the flange to cause adhesion.

[0067] In the sixth step, the blocking block 41 is moved to the top of the flange to block the welding slag from passing over the flange. At the same time, the buffer plate 413 slows down the splashing welding slag, and at the same time, the welding slag is guided to fall into the inside of the drawer box 411 through the rebound of the reflection block 414, thereby collecting the welding slag.

[0068] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered by the scope of protection of the present invention.
