DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] See also Figures 1-6 In one embodiment of the present invention, a loader intelligent welding device has a relative first direction x, a second direction y, and a third direction z. The loader intelligent welding device includes a clamping arm module and a grinding module. Two groups of the clamping arm modules are used to position and clamp the loader parts to be welded. The grinding module moves between the parts and grinds according to the roughness of the edges of the parts to be welded; the clamping arm module includes a base assembly 1 and a clamping arm assembly 2, and the two groups of the clamping arm assemblies 2 are slidably arranged on the base assembly 1; the grinding module includes a grinding assembly 3, and the grinding assembly 3 includes The bottom bracket 301, the middle bracket 302, the top bracket 303, the side guide rod 304, the side slide 305 and the grinding rod 306, the bottom bracket 301 is slidably set on the base assembly 1, the middle bracket 302 is longitudinally slidably assembled on the bottom bracket 301, the top bracket 303 is fixedly assembled on the middle bracket 302, and the side guide rods 304 are fixedly assembled on both sides of the top bracket 303. The side slide 305 is elastically slidably inserted on the side guide rod 304, and the end of the side slide 305 is also rotatably assembled with a grinding rod 306, and the grinding rod 306 slides and abuts against the welding edge of the part to be welded.

[0022] In actual application of this embodiment, when the device is used to weld loader parts, the main base plate 101 in the base assembly 1 is provided with a second guide rail 103 along the first direction x, and the main base plate 101 is provided with a first guide rail 102 along the second direction y. The clamping arm assembly 2 is slidably assembled on the main base plate 101 along the second direction y, and the bottom bracket 301 is slidably provided on the main base plate 101 along the first direction x. The bottom bracket 301 and the middle bracket 302 are slidably connected to each other, so that the middle bracket 302 can move along the negative direction of the third direction z in the telescopic state, thereby moving the grinding module to the bottom of the part to be welded. At this time, the welding of the parts can be achieved by using the welding gun 6 provided on the other side of the bottom bracket 301. Side guide rods 304 are arranged on both sides of the top bracket 303 fixedly provided on the middle bracket 302. The two groups of the The side slides 305 are slidably assembled on the side guide rods 304, and the ends of the side slides 305 are rotatably assembled with grinding rods 306. When the middle bracket 302 follows the bottom bracket 301 to move along the first direction x, the grinding rod 306 moves on one side of the welding edge, and at the same time adjusts the position of the side slide 305 in the first direction x according to the size of the concave and convex side of the welding edge. When the welding edge side of the part is a convex shape, the grinding rod 306 continuously grinds the welding edge during the movement, and grinds off the excess welding edge to make the parts fit more tightly during the seam matching process. When the welding edge side of the part is a concave shape, the grinding rod 306 roughly grinds the welding edge during the movement, and then grinds off the rust residue on the welding edge to prevent it from affecting the quality of the weld. Therefore, grinding operations of different depths are performed according to the concave and convex conditions of the welding edges of the two groups of parts to make the weld tighter.

[0023] In one case of this embodiment, the movements of the clamping arm assembly 2 and the bottom bracket 301 are driven by an external driving source, and the specific structure of the external driving source is not limited here.

[0024] See also Figure 2 and Figure 6 In a preferred embodiment of the present invention, the clamping arm assembly 2 includes a clamping arm bracket 201, a guide groove 202, a splint 203, a double-headed screw rod 204 and a clamping arm driver 205. The clamping arm bracket 201 is slidably assembled on the first guide rail 102. The clamping arm bracket 201 is also provided with a guide groove 202. The two groups of splints 203 are limitedly slidably assembled in the guide groove 202. The bottom of the clamping arm bracket 201 is also provided with a double-headed screw rod 204 on a fixed axis. The two ends of the double-headed screw rod 204 are respectively engaged with the two groups of splints 203. The clamping arm driver 205 is fixedly arranged in the clamping arm bracket 201 and the movable axis of the clamping arm driver 205 is connected with the double-headed screw rod 204 for transmission.

[0025] During actual application of this embodiment, the clamping arm bracket 201 moves along the second direction y, and the two groups of clamping plates 203 on the clamping arm bracket 201 slide along the guide groove 202, and the double-headed screw 204 arranged on the bottom side of the clamping arm bracket 201 can engage and drive the two groups of clamping plates 203 to move in opposite directions in the first direction x under the drive of the clamping arm driver 205, and then the parts are clamped by the clamping plates 203. At the same time, the parts on the two groups of clamping arm brackets 201 are installed with the grinding module as the mirror surface during the assembly process, so that the distance between the grinding module and the two groups of parts is equal.

[0026] See also Figure 3 In a preferred embodiment of the present invention, the grinding assembly 3 also includes a transmission rack 307, a reference bracket 308, a transmission gear 309, a transmission wheel 310, a reference tooth plate 311 and a pitch adjustment wheel 312. A transmission rack 307 is also fixedly provided on one side of the side slide 305. The reference bracket 308 is slidably assembled on the bottom bracket 301 and a transmission gear 309 is rotatably assembled on the reference bracket 308. The transmission gear 309 and the transmission rack 307 are meshed with each other, the transmission wheel 310 and the transmission gear 309 are coaxially fixedly connected, the reference tooth plate 311 is fixedly provided on one side of the reference bracket 308, and the pitch adjustment wheel 312 is fixedly assembled on the top bracket 303 and meshed with the two groups of reference tooth plates 311.

[0027] In actual application of this embodiment, when the middle bracket 302 follows the bottom bracket 301 to move in the first direction x, the grinding rod 306 synchronously abuts against one side of the weld edge and adjusts the position of the side slide 305 in the second direction y according to the concave and convex shape of the weld edge. The spacing wheel 312 is assembled on the top bracket 303 with a fixed axis rotation, and the spacing wheel 312 can switch its locking state. By adjusting the rotation inclination angle of the spacing wheel 312, the two sets of reference tooth plates 311 can be engaged and driven to move, so that the two sets of reference tooth plates 311 drive the two sets of reference brackets 308 to slide synchronously, thereby setting a fixed width dimension, and during the movement, the concave and convex state of the weld edge is measured with this width dimension. When the side slide 305 moves in the second direction y, the side slide 305 engages and drives the transmission gear 309 to rotate, so that the transmission wheel 310 on the coaxial side of the transmission gear 309 rotates synchronously.

[0028] See also Figure 3In a preferred embodiment of the present embodiment, the driving mechanism 4 includes a driver 401, a first linkage arm 402, a second linkage arm 403, a center shaft 404, a first synchronous belt 405 and a second synchronous belt 406. The driver 401 is fixedly assembled on the center bracket 302, one end of the first linkage arm 402 is rotatably sleeved on the movable shaft of the driver 401, and the other end of the first linkage arm 402 is rotatably assembled with the center shaft 404, one end of the second linkage arm 403 is rotatably sleeved on the center shaft 404, and the other end of the second linkage arm 403 is rotatably sleeved on the bottom of the side slide 305, the driver 401 and the center shaft 404 are connected by the first synchronous belt 405, and the center shaft 404 and the grinding rod 306 are connected by the second synchronous belt 406.

[0029] In actual application of this embodiment, the driver 401 is fixedly set on the central bracket 302, and a first linkage arm 402 is sleeved on the movable shaft of the driver 401. The end of the first linkage arm 402 is rotatably equipped with a second linkage arm 403 through a central shaft 404, and the second linkage arm 403 is rotatably sleeved on the bottom of the grinding rod 306, so that the driver 401 drives the central shaft 404 to rotate through the first synchronous belt 405 in the driving state, and the central shaft 404 drives the grinding rod 306 to rotate through the second synchronous belt 406. Since the first linkage arm 402 and the second linkage arm 403 are rotatably connected through the central shaft 404, when the side slide 305 moves in the second direction y, the driver 401 and the grinding rod 306 always maintain a transmission state, and then the grinding rod 306 is driven to rotate through the driver 401, thereby continuously grinding the weld edge.

[0030] See also Figure 3 and Figure 6 In a preferred embodiment of the present invention, the loader intelligent welding device further includes an adjustment component 5, which includes a driven wheel 501, a driven gear 502, a driven gear plate 503, a square groove 504, a pulling rod 505, a sensor 506 and a trigger 507. The driven wheel 501 is fixedly mounted on the central bracket 302, and the driven wheel 501 is connected to the transmission wheel 310 in a transmission manner. The driven wheel 501 is coaxially fixed with a driven gear. Wheel 502, the driven gear plate 503 is slidably assembled on the central bracket 302, and one end of the driven gear plate 503 is engaged with the driven gear 502, and the other end of the driven gear plate 503 is provided with a square groove 504, the sensor 506 is fixedly set on the central bracket 302, and the trigger 507 is slidably assembled on the sensor 506, one end of the pulling rod 505 is slidably inserted in the square groove 504, and the other end of the pulling rod 505 is rotatably assembled on the trigger 507.

[0031] When this embodiment is actually used, when the device is grinding the weld edge, the bottom bracket 301 is driven by an external driving source and moves at a constant speed along the second guide rail 103. The sensor 506 is electrically connected to the external driving source. When the grinding rod 306 is grinding the convex edge of the weld edge, the side slide 305 moves along the second direction y toward the side close to the top bracket 303, so that the transmission gear 309 drives the transmission wheel 310 to rotate synchronously during the rotation process. At this time, the driven wheel 501 linked to the transmission wheel 310 rotates synchronously, so that the driven gear 502 at one end thereof engages and drives the driven gear plate 503 to slide. The driven gear plate 503 is limitedly assembled along the second direction y, and during the movement of the driven gear plate 503, when the side grinding rod 306 is in the state of grinding the convex edge, the side The driven tooth plate 503 moves toward the end away from the sensor 506. At this time, the pulling rod 505 pulls the trigger 507 toward the positive direction of the first direction x while following the movement of the driven tooth plate 503, so that the sensor on the side of the sensor 506 controls the external drive source to slow down, thereby increasing the grinding time between the grinding rod 306 and the convex edge to achieve better grinding effect. When the grinding rod 306 on this side is in the state of grinding the concave edge, the driven tooth plate 503 on this side moves toward the end close to the sensor 506. At this time, the pulling rod 505 slides in the square groove 504 and does not interfere with the movement of the trigger 507 in the first direction x. The two groups of pulling rods 505 are movably connected to the trigger 507, so that when the grinding rod 306 on either side is grinding the convex edge, the sensor 506 can control the external drive source to slow down.

[0032] The above embodiment of the present invention provides an intelligent welding device for a loader. By arranging two groups of clamping arm brackets 201 for clamping parts on the main base plate 101, and arranging a grinding component 3 that moves to fit the weld edge between the two groups of clamping arm brackets 201, the grinding time can be adaptively adjusted according to the concave and convex state of the weld edge, so that the parts can fit more closely during the seam fitting process, thereby increasing the strength of the welding.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
