Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a welding equipment for processing automotive parts. Background Technology

[0002] The leaf spring suspension bracket is a core load-bearing component of heavy-duty trucks and construction machinery suspensions. Made of thick-walled cast steel in a single piece, it withstands alternating and impact loads over long periods, requiring extremely high standards for welding quality and flaw detection. This bracket connects the vehicle frame to the leaf springs; defects such as welding cracks and insufficient fusion can cause suspension failure and lead to safety accidents. Therefore, automated robotic welding is used in production to ensure consistent and stable welding quality.

[0003] To reduce frictional loss, wear-resistant plates need to be welded to the contact surfaces of the lifting lug brackets. The wear-resistant plates are made of a different material than the cast steel substrate, resulting in a large heat input during welding, which generates a large amount of high-temperature welding slag and metal spatter. Scattered welding slag can easily scratch workpieces and tooling, cause fires, and is difficult to recycle and dispose of in a unified manner, failing to meet solid waste management regulations. Therefore, welding workstations are equipped with dedicated collection tanks to centrally collect welding slag.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Conventional welding equipment is not equipped with a dedicated slag collection mechanism, resulting in welding slag splattering and accumulating everywhere, making subsequent manual cleaning a large-scale and cumbersome task.

[0021] like Figure 1As shown, this embodiment provides a welding equipment for processing automotive parts, used to weld the wear-resistant plate 400 on the leaf spring hanger bracket 300. The welding equipment includes four sets of welding platforms 100, each equipped with a slag collection mechanism 200. The four sets of welding platforms 100 are circumferentially distributed around the welding robot. In this embodiment, the welding platforms 100 are grouped in pairs. When welding fixtures are placed on two of the welding platforms 100, the welding robot welds them. After welding, the welding robot welds the workpieces on the other two welding platforms 100. The welded workpieces on the other two sets are then cooled or subjected to other operations. Alternating between the two sets of welding can improve welding efficiency.

[0022] like Figure 2 and Figure 3 As shown, the welding platform 100 includes a platform support 101. A platform surface 102 is fixedly mounted on the top of the platform support 101. Several partitions 103 are fixedly mounted on the platform surface 102. A crossbar 104 is fixedly mounted on the top of each partition 103. A fixing mechanism is provided on the crossbar 104 between each set of partitions 103. Each fixing mechanism includes a fixing seat 107. An adjusting rod 106 and a top rod 105 are rotatably mounted on the fixing seat 107. The top rod 105 is L-shaped and includes a pressure head. The adjusting rod 106 and the top rod 105 are movably connected; that is, when the adjusting rod 106 is rotated upwards, the adjusting rod 106 drives... The rotation of the top rod 105 on the fixed seat 107 realizes the rotation of the top rod 105 and the positioning function of the rotation and downward pressure. Each side of several partitions 103 is fixed with a limit block 108. In use, the adjusting rod 106 and the top rod 105 are rotated upward to avoid obstructing the feeding of the steel leaf spring lifting lug bracket 300. The steel leaf spring lifting lug bracket 300 is installed from the partition 103 to the welding station. One side of the vertical plate of the steel leaf spring lifting lug bracket 300 is in contact with the limit block 108, and the other side is pressed by rotating the top rod 105 to achieve the pressing head of the steel leaf spring lifting lug bracket 300, and finally the positioning of the steel leaf spring lifting lug bracket 300 is achieved.

[0023] like Figure 3 As shown, the welding station on the table 102 is hollowed out, and several sets of support plates 121 are provided in the hollowed-out area. Slide rods 122 are fixed on the support plates 121, such as... Figure 1 The platform 102 shown is also provided with several sliding grooves 124, and several sliding rods 122 are respectively slidably engaged with several sliding grooves 124. Scrapers 111 are fixedly connected to the tops of several adjacent limiting blocks 108, and baffles 109 are slidably provided between adjacent limiting blocks 108. Connecting rods 110 are fixedly connected to the tops of several baffles 109. Figure 4 As shown, an extension rod 115 is fixedly provided on the side of the connecting rod 110, such as... Figure 3As shown, the welding platform 100 also includes two sets of drive rods 113, and several sets of adjusting rods 106 are located between the two sets of drive rods 113. A rotating arm 112 is rotatably mounted on the end partition 103, and both sets of adjusting rods 106 are fixedly mounted on the rotating arm 112. Figure 3 As shown, a first gear 118 is fixedly installed at the rotatable connection between the rotating arm 112 and the partition 103. A gearbox 114 is also fixedly installed on the partition 103. The gearbox 114 has two sets of output shafts. One set of output shafts is driven by the first gear 118 through the second gear. The other set of output shafts on the gearbox 114 is coaxial with and fixedly connected to the first threaded rod 116. A limit rod 117 is also fixedly installed on the gearbox 114. Figure 3 As shown, the first threaded rod 116 is threadedly engaged with the extension rod 115, and the extension rod 115 is slidably engaged with the limiting rod 117, as follows. Figure 2 As shown, the support plate 121 is slidably disposed in the slide groove 124 via the slide rod 122. In this embodiment, several sets of slide rods 122 slide synchronously. Specifically, each of the slide rods 122 has a first rack at its bottom. A third gear is rotatably disposed in the slide groove 124. The third gear meshes with the first rack to drive the slide rod 122. The several third gears are coaxial and fixedly connected. A first drive box 120 is fixedly disposed on the platform 102. The first drive box 120 includes a drive source and two sets of output shafts. One set of output shafts is coaxial and fixedly connected to the central shaft of the several third gears, and the other set of output shafts is coaxial and fixedly connected to the first threaded rod 116.

[0024] like Figure 1 As shown, a slag collection mechanism 200 is slidably installed below the hollow area of ​​the welding station on the table 102. The slag collection mechanism 200 slides and cooperates with the platform support 101 below the table 102 to realize welding. A detachable baffle 123 is provided at the edge of the hollow area of ​​the welding station on the table 102.

[0025] The working principle of welding platform 100: Figures 1 to 4As shown, during use, the leaf spring lifting lug bracket 300 is placed between two sets of limiting blocks 108. The fixing mechanism is rotated to fix the base of the leaf spring lifting lug bracket 300 between the limiting blocks 108 and the pressure head. The connecting arm of the leaf spring lifting lug bracket 300 is placed horizontally on the support plate 121. The support plate 121 is also equipped with limiting pins to limit the transition area of ​​the connecting arm, preventing displacement of the connecting arm during welding. After the leaf spring lifting lug bracket 300 is fixed, the wear-resistant plate 400 is placed in the designated position, and the welding robot is driven to weld the wear-resistant plate 400 onto the leaf spring lifting lug bracket 300. During welding, weld slag will splash onto the baffle 109 and the stop bar 123. After welding, the first drive box 120 can rotate its two sets of output shafts. One set of shafts enables several third gears to rotate synchronously and drives the support plate 121 to move laterally. The other set of output shafts drives the first threaded rod 116 to rotate and, through the extension rod 115, enables several sets of baffles 109 to move upward. During the upward movement of the baffles 109, the scraper 111 scrapes off the weld slag adhering to it, and the falling weld slag is blown into the weld slag collection mechanism 200 by the negative pressure or blowing mechanism for collection. The first threaded rod 116 then enables the rotation of the rotating arm 112 through the gearbox 114. The two sets of drive rods 113 on the rotating arm 112 enable the rotation of the adjusting rod 106, ultimately realizing the rotation of the pressure head.

[0026] That is, after welding is completed, as the pressure head on the adjusting rod 106 rotates and opens, the other side of the leaf spring lifting lug bracket 300 is fixed. At this time, the support plate 121 moves synchronously, causing the connecting arm of the upper limit of the leaf spring lifting lug bracket 300 to move outward synchronously, thus pushing the entire leaf spring lifting lug bracket 300 outward. During the outward movement of the leaf spring lifting lug bracket 300, several sets of baffles 109 open upward simultaneously, and the slag adhering on the baffles 109 is intercepted and scraped off by the scraper 111, and sucked into the welding slag collection mechanism 200 by the negative pressure mechanism for centralized collection. It should be emphasized that the core improvement of this embodiment lies in the following: This equipment is optimized for the welding conditions of the steel plate spring lifting lug bracket 300 and the wear-resistant plate 400, solving the defects of traditional equipment such as welding slag spatter, difficulty in cleaning, and poor collection. It can achieve welding slag shielding, automatic scraping, and closed-loop centralized collection. During welding operations, the baffle 123 and the baffle 109 can block high-temperature welding slag and spatter in all directions, restricting the area where welding slag is scattered and optimizing the workshop environment. After welding is completed, the baffle 109 is driven to rise and fall, the support plate 121 moves, and the pressure head flips. The scraper 111 automatically scrapes off the welding slag attached to the baffle 109, and then the waste slag is sent to the welding slag collection mechanism 200 for collection by relying on negative pressure and the blowing mechanism, eliminating the manual slag removal process and reducing labor costs. The workpiece discharge and slag removal actions are linked synchronously. When the adjusting rod 106 releases the pressure head and the support plate 121 pushes the workpiece out, the slag removal is completed simultaneously, improving production efficiency. The unified collection of welding slag facilitates recycling and transportation, meeting industrial solid waste management standards.

[0027] Example 2 Understandably, in Example 1, ordinary collection tanks are currently used to directly collect welding slag. High-temperature molten slag accumulates and dissipates heat slowly, easily sintering and sticking to the tank walls. Although conventional water-cooled tanks can reduce large slag clumps, they cannot prevent thin layers of welding slag and small spatter from sticking to the inner wall. The slag can only be removed manually with tools, which is time-consuming and labor-intensive, disrupting normal production.

[0028] like Figure 5 As shown, to solve the above problems, this embodiment proposes a self-cleaning welding slag collection mechanism 200, including an external collection box 201. An internal collection box is detachably installed inside the external collection box 201. The internal collection box is in direct contact with the high-temperature welding slag, and the welding slag is cooled. The cooled welding slag directly enters the external collection box 201 for centralized collection. The internal collection box is equipped with a mounting frame bracket 202. The mounting frame bracket 202 has a rectangular structure, and mounting positions are provided in the right-angled areas of the external area of ​​the mounting frame bracket 202. Several sets of first rotating rollers 203 are rotatably provided on the four sides of the mounting frame bracket 202, and several sets of second rotating rollers 204 are rotatably provided on the bottom area of ​​the mounting frame bracket 202. Each of the first rotating rollers 203 and the second rotating rollers 204 has a chamber filled with circulating water. In this embodiment, each side of the mounting frame bracket 202 is provided with two sets of first rotating rollers 203, for a total of eight sets of first rotating rollers 203.

[0029] like Figure 6 and Figure 7As shown, the welding slag collection mechanism 200 includes a water inlet 209, to which a water distribution pipe 208 is connected. The water distribution pipe 208 has four sets of connecting ports, each connected to two sets of first rotating rollers 203 on an adjacent side. On one side, a first rotary joint 210 connects the two first rotating rollers 203 to their corresponding connecting ports. The first rotary joint 210 is concentrically mounted with a fourth gear 205. The water inlet of the first rotary joint 210 connects to the corresponding connecting port, and the water outlet of the first rotary joint 210 connects to the corresponding first rotating roller 203. On the other side, a second rotary joint 206 connects the two first rotating rollers 203 to their corresponding connecting ports. The second rotary joint 206 is concentrically mounted with a fifth gear 207. Synchronous rotation of the four sets of first rotating rollers 203 is achieved by driving the two fourth gears 205 and the fifth gear 207 to rotate synchronously. Figure 5 As shown, this embodiment also provides an outlet 221 at the diagonal of the inlet 209. The structure of the outlet 221 is exactly the same as that of the inlet 209. In this embodiment, the mounting frame bracket 202 is provided with two connecting pipes 220 at the two diagonal positions other than the inlet 209 and the outlet 221. The two ends of the connecting pipe 220 are respectively connected to the first rotating roller 203 on the adjacent side, and the two ends of the connecting pipe 220 are respectively connected to the first rotating roller 203 on the adjacent side through the fourth rotating joint 218 and the third rotating joint 219.

[0030] The flow principle of circulating water within several first rotating rollers 203, such as... Figure 8 As shown, the inlet 209 is connected to an external water source. Water flows along the four sets of first rotating rollers 203 on the adjacent sides of the four sets of connecting ports on the inlet 209. The first rotating rollers 203 on the adjacent sides are supplied with water through the connecting pipe 220 to the four sets of first rotating rollers 203 on the other two sides. Finally, the water is discharged at the outlet 221, completing the circulating water transport among the first rotating rollers 203.

[0031] like Figure 7 As shown, the bottom of the water distribution pipe 208 is connected to the conversion assembly 211 via a steering head. The conversion assembly 211 has several connection ports, which are respectively connected to several second rotating rollers 204 at the bottom. The water distribution pipe 208 can simultaneously supply water to the first rotating roller 203 and the second rotating roller 204. Figure 9 and Figure 10 As shown, a fifth rotary joint 226 is provided between several second rotating rollers 204 and several connecting ports. A sixth gear 225 is concentrically and fixedly provided on the fifth rotary joint 226. A second rack 227 is also slidably provided above several sixth gears 225. The second rack 227 meshes with several sixth gears 225 for transmission. The rotation of several sixth gears 225 can be realized by moving the second rack 227 laterally.

[0032] like Figure 12As shown, a second threaded rod 222 is rotatably provided at the bottom of the mounting frame bracket 202, and a mounting ear 224 is fixedly provided on the second rack 227. The mounting ear 224 and the second threaded rod 222 are threadedly engaged. Figure 7 and Figure 9 As shown, a rack assembly 212 is slidably mounted on a mounting frame bracket 202 with an inlet 209. A third rack 213 and a fourth rack 214 are fixedly mounted on adjacent sides of the rack assembly 212. The third rack 213 meshes with several fourth gears 205 for transmission, and the fourth rack 214 meshes with a fifth gear 207 for transmission. An extension arm 215 is provided at the bottom of the rack assembly 212. A third threaded rod 216 is also rotatably mounted on the mounting frame bracket 202. The third threaded rod 216 and the extension arm 215 are threadedly engaged. A second drive box 217 is fixedly mounted on the mounting frame bracket 202. The second drive box 217 is provided with two sets of output shafts. The two sets of output shafts are coaxial with and fixedly connected to the third threaded rod 216 and the second threaded rod 222, respectively.

[0033] The outlet 221 is also equipped with a first rotary joint 210, a fourth gear 205, a second rotary joint 206, a fifth gear 207, a water distribution pipe 208, a conversion component 211 (water outlet), a rack assembly 212, a third rack 213, a fourth rack 214, an extension arm 215, a third threaded rod 216, a second drive box 217 (only the gear assembly without a drive source), a second threaded rod 222, a mounting ear 224, and a second rack 227.

[0034] The rotation principle of several first rotating rollers 203 and second rotating rollers 204: as follows Figure 7 As shown, during normal welding operations, the first rotating roller 203 and the second rotating roller 204 are kept stationary, and the circulating water inside them is kept in a continuous flow. To avoid condensation, the temperature of the circulating water is higher than that of the normal cooling water. When the weld spatter falls into the slag collection mechanism 200, it comes into contact with the first rotating roller 203 and the second rotating roller 204. The circulating water helps prevent the slag from sintering and agglomerating over a large area. The low-temperature roller surface quickly quenches the spatter, reducing metallurgical adhesion between the slag and the metal wall. The cooled slag falls into the... The welding slag collection mechanism 200 collects slag. During welding pauses, the second drive box 217 can be driven to synchronously rotate the third threaded rod 216 and the second threaded rod 222. The third threaded rod 216 can raise and lower the rack assembly 212. The third rack 213 on the rack meshes with several fourth gears 205, and the fourth rack 214 meshes with the fifth gear 207, thus rotating the adjacent first rotating roller 203. The second threaded rod 222 drives the second rack 227 to move back and forth. The second rack 227 meshes with the sixth gear 225, thus rotating the several second rotating rollers 204. Figure 14As shown, the second rotating roller 204 has a second rack 227 on both sides. The second rack 227 at the outlet 221 moves through the sixth gear 225 and drives the second threaded rod 222 to rotate. The third threaded rod 216 rotates through the second drive box 217 on the other side, and finally the rack group 212 at the outlet 221 moves up and down, realizing the rotation of the adjacent first rotating roller 203 at the outlet 221, and thus realizing the synchronous rotation of several first rotating rollers 203 and second rotating rollers 204.

[0035] It should be emphasized that the core improvement of this embodiment lies in: 1. This equipment can intermittently drive the first rotating roller 203 and the second rotating roller 204 to rotate, avoiding the long-term accumulation of welding slag in the same position on the roller body, which would cause the slag layer to thicken, block the heat exchange surface, and reduce the water cooling effect. Relying on the second drive box 217 to drive the third threaded rod 216 and the second threaded rod 222 to move synchronously, and through the rack group 212, the second rack 227 and the gear meshing transmission, the two sets of rollers can rotate synchronously, continuously change the heat exchange working surface, stabilize the water cooling heat dissipation efficiency, prevent cooling failure and welding slag adhesion, reduce manual cleaning, and improve the continuous stability of welding slag collection.

[0036] 2. If welding slag adheres to the surfaces of the first rotating roller 203 and the second rotating roller 204, the two sets of rollers can be driven to rotate synchronously, causing the adjacent first rotating roller 203 and the adjacent second rotating roller 204 to rub against each other. Relying on the mechanical friction of the contact surfaces of the rollers, the welding slag adhering to the outer wall of the rollers is automatically scraped off. There is no need for manual scraping and cleaning of the slag on the roller surface, simplifying the maintenance process, continuously ensuring the cleanliness of the heat exchange surface of the rollers, and stabilizing the water cooling effect.

[0037] It should be noted that, such as Figure 14 As shown, in this embodiment, the plurality of second rotating rollers 204 can also be configured as meshing rotation type, with the sixth gear 225 at one end of the plurality of second rotating rollers 204 spaced apart, and the sixth gear 225 at the other end of the second rotating rollers 204 also spaced apart. Both sets of second drive boxes 217 are provided with drive sources, and each set of drive sources drives the corresponding second rack 227 to rotate, and the second rack 227 then drives the corresponding sixth gear 225 to rotate, so as to realize the meshing rotation of adjacent second rotating rollers 204, which can realize the crushing of welding slag on them.

[0038] Example 3 It is understandable that in Embodiment 2, if the second rotating roller 204 were a complete cylinder, it would be impossible to discharge the welding slag. Therefore, in this embodiment, the second rotating roller 204 is designed with an arc-shaped groove 228, such as... Figure 12 and 13As shown, several second rotating rollers 204 are semi-circular and have arc-shaped grooves 228. When welding slag enters and contacts the first rotating roller 203 on the side and is cooled, it can fall freely onto the second rotating roller 204. When the second rotating roller 204 rotates to the state where the arc-shaped grooves 228 face upward, the welding slag can fall along the gap between the adjacent second rotating rollers 204 into the external collection box 201 for centralized collection, avoiding the continuous accumulation of welding slag, which would cause the water-cooled surface to be continuously covered and the cooling effect to be poor.

[0039] It should be noted that, such as Figure 13 As shown, the number and shape of the arc-shaped grooves 228 in this embodiment are not limited, including a single arc-shaped groove 228.

[0040] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
