Description

Technical Field

[0001] The invention relates to the technical field of welding manipulators, in particular to a forklift wheel rim process welding manipulator based on intelligent control. Background Art

[0002] As an important part of forklifts, forklift wheel rims are directly related to the safety and stability of forklift driving. Forklift wheel rims are generally made of multiple parts, and the joints of these parts need to be welded. Rim welding is a key process in the manufacturing process of forklift wheel rims, requiring the weld to have good strength, sealing and appearance quality. Traditional forklift wheel rim welding mostly adopts manual welding. With the increase in forklift production, manual welding can no longer meet the large-scale and high-efficiency production needs; Different welders have different technical levels and operating habits. Even the same welder may have different conditions at different times, which leads to large fluctuations in welding quality. For example, deviations in weld width and height may affect the strength and dynamic balance performance of the rim, and defects such as pores and cracks may occur at a high rate.

[0003] In combination with the above content, it should be explained that: Chinese patent application number CN2025100494264 discloses a wheel welding device with a rotatable workstation, which still adopts a simple rim-by-rim limited loading and clamping, and performs welding after unidirectional fixing, which easily leads to welding slag, spatter and other impurities adhering to the periphery of the rim welding area, causing damage to the rim surface and affecting subsequent welding processing. At the same time, the step-by-step loading and unloading and replacement welding processing of a single rim is inefficient as a whole. In view of the above technical defects, a solution is now proposed. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1 - Figure 8 As shown, this embodiment is a forklift wheel rim process welding robot based on intelligent control, including a central conveying frame 1, a plug-in kit 103 is arranged at the top center of the central conveying frame 1, a clamp limiting lifting frame 4 is arranged on one side of the plug-in kit 103, welding lifting frames 2 are symmetrically arranged at both ends of the clamp limiting lifting frame 4, a plurality of welding lifting frames 2 are sleeved with welding machine components 3 on the surface, and a slag collecting movable component 5 is arranged on the other side of the plug-in kit 103.

[0021] The forklift wheel rim to be processed is transferred and limited on the plug-in kit 103, and is lowered steadily, so that the multiple groups of bolts and bosses provided on the top of the plug-in kit 103 are inserted into the middle holes of the forklift wheel rim, forming a preliminary limit for the forklift wheel rim, and the top surface of the side bracket 104 is provided with a rubber sleeve, which contacts the outer body of the forklift wheel rim which is flat and limited above the plug-in kit 103, so as to lift it in a balanced manner, and under the coordinated movement of the central conveying frame 1 and the moving bracket 101, the forklift wheel rim with overall limit is moved close to the lifting top frame 105.

[0022] The slag collecting movable component 5 includes a balance plate 501 and a receiving plate 503. Slag collecting adjustment columns 6 connected to the central conveying frame 1 are symmetrically arranged at both ends of the balance plate 501. The slag collecting adjustment columns 6 and the bottom of the lifting top frame 105 are provided with multiple groups of corresponding cooperative cylinders. The cooperative cylinders drive the lifting top frame 105 to slide up synchronously. The top surface of the lifting top frame 105 is sleeved with an anti-slip rubber sleeve, which contacts the bottom surface of the forklift wheel rim and reduces the friction damage to the forklift wheel rim surface. At the same time, the forklift wheel rim is continuously lifted and slid upward until it is separated from the plug-in kit 103 and close to the semi-circular arc frame 402.

[0023] A movable bracket 101 is slidably sleeved at the center of the top of the central conveyor frame 1, a support rod 102 connected to the plug-in kit 103 is arranged on the top of the movable bracket 101, a plurality of side brackets 104 are arranged in a circular array on the outer periphery of the top of the support rod 102, and a lifting top frame 105 is arranged in a circular array on both sides of the top of the central conveyor frame 1.

[0024] A lifting and telescopic cylinder arm 401 is slidably sleeved on the inner wall of the clamp-limiting lifting frame 4, and a rotary cylinder 407 sleeved with the semi-circular frame 402 is arranged on the arm rod of the lifting and telescopic cylinder arm 401. An electromagnet frame 405 is sleeved on the middle part of the inner wall of the semi-circular frame 402, and inner suction cups 404 embedded in the center of the inner wall of the semi-circular frame 402 are symmetrically arranged at both ends of the electromagnet frame 405.

[0025] The clamp limit lifting frame 4 drives the semi-circular frame 402 to perform adaptive adjustment according to the height of the forklift wheel rim being lifted by lifting the telescopic cylinder arm 401, so that the semi-circular frame 402 is close to the arc-shaped recessed area on the outer periphery of the forklift wheel rim. The lifting telescopic cylinder arm 401 drives the semi-circular frame 402 to move horizontally close to the outer periphery of the forklift wheel rim through the rotating cylinder 407. When the two are close to each other and retain a certain gap, the outer arc cylinder part 403 drives the extended arc arm rod 406 to slide outward from both ends of the semi-circular frame 402. At the same time, the semi-circular frame 402 further moves horizontally, causing the semi-circular frame 402 and the extended arc arm rod 406 to be slightly attached to the outer periphery of the forklift wheel rim until they cooperate with the semi-circular frame 402 to form an embracing clamping mechanism.

[0026] A plurality of groups of outer arc cylinder parts 403 transmission-connected with the extended arc arm 406 are symmetrically arranged on the outer wall of the semicircular arc frame 402, and an outer suction cup 408 is arranged on the inner wall of the extended arc arm 406. When the semicircular arc frame 402 and the extended arc arm 406 are close to the outer periphery of the forklift wheel rim, the electromagnet frame 405 is first energized to generate magnetic force for adsorbing and fixing the metal body of the forklift wheel rim, and the inner suction cup 404 and the outer suction cup 408 are contacted with the outer periphery of the forklift wheel rim by the movement of the semicircular arc frame 402 and the extended arc arm 406. With the cooperation of the external air supply equipment, negative pressure is generated by suction and the forklift wheel rim is fixed by multi-point suction. After waiting for the embracing clamping mechanism to limit the forklift wheel rim, the lifting top frame 105 slides down and disengages.

[0027] The end surface of the welding lifting frame 2 is recessed with a long rectangular groove, and an inner lifting cylinder 201 is embedded in the long rectangular groove. The welding lifting frame 2 is symmetrically installed at both ends of the clamping limit lifting frame 4 and fixedly connected to the central conveying frame 1.

A lowering cylinder arm 303 sleeved with an adjusting mechanical arm 304 is arranged at the bottom of the rotary cylinder arm 301. A welding sleeve 305 is arranged at the bottom of the adjusting mechanical arm 304.

[0029] The welding lifting frame 2 drives the moving slider 302 to move up and down along the long rectangular groove through the inner lifting cylinder 201, and is used in conjunction with the clamp limiting lifting frame 4. The rotary cylinder arm 301 drives the lowering cylinder arm 303 to extend outward, and the lowering cylinder arm 303 drives the adjusting mechanical arm 304 to further extend outward. The adjusting mechanical arm 304 is connected to the welding head through the welding sleeve 305, and according to the welding needs, the surface of the forklift wheel rim that is limited is subjected to multi-point coordinated welding. It should be noted that the welding process can be carried out from bottom to top, so that the slag, spatter and impurities generated in the welding process are directly dropped without causing pollution to the surface of the forklift wheel rim.

[0030] After the single-sided welding with the forklift wheel rim facing downward is completed, the robot arm 304 is adjusted to expand outward and temporarily leave to reserve enough space for the clamping limit lifting frame 4 to clamp the forklift wheel rim and rotate. The rotary cylinder 407 drives the semi-circular arc frame 402 to rotate, thereby driving the overall limited forklift wheel rim to rotate, so as to cooperate with the welding machine component 3 to perform welding on the other side.

[0031] Embodiment 2: This embodiment is a forklift wheel rim process welding robot based on intelligent control, including a semi-circular arc frame 402 slidably arranged on the inner wall of the clamp limit lifting frame 4, and an extended arc arm rod 406 is slidably embedded in the two ends of the semi-circular arc frame 402, and the welding machine component 3 includes a rotary cylinder arm 301 and an adjustment mechanical arm 304.

[0032] While the forklift wheel rim is suspended and clamped, a slag collecting adjusting cylinder connected to the slag collecting slider 601 is provided inside the slag collecting adjusting column 6, which is used to lift the slag collecting slider 601 to slide up and down along the L-shaped groove, and cooperate with the slag collecting rotating motor 602 to adjust the position of the slag collecting movable component 5. When the balance plate 501 is close to the bottom of the forklift wheel rim, the inner push cylinder 502 drives the receiving plate 503 to slide and expand toward the welding lifting frame 2, and the suction ring 505 is connected to the external air supply equipment pipeline to form a negative pressure air gathering area under the forklift wheel rim, which helps to guide the high temperature, slag, spatter and impurities generated by welding to fall onto the receiving plate 503.

[0033] An inner push cylinder 502 connected to the receiving plate 503 is arranged on the inner end surface of the top of the balance plate 501, and a ball bearing that is in sliding contact with the receiving plate 503 is arranged on the top surface of the balance plate 501. A plurality of groups of concentric circle-structured suction rings 505 are embedded in the center of the top of the receiving plate 503, and a guide plate 504 is arranged on the side of the receiving plate 503 away from the central conveying frame 1.

[0034] An L-shaped slot is recessed at the inner wall corner of the slag collecting adjustment column 6 facing the welding lifting frame 2, a slag collecting slider 601 is slidably arranged inside the L-shaped slot, a slag collecting rotating motor 602 is embedded in the inner wall of the slag collecting slider 601, and the slag collecting rotating motor 602 is sleeved on the outer walls of both ends of the balance plate 501.

[0035] After welding is completed, the inner push cylinder 502 drives the receiving plate 503 to reset, and the slag collecting rotating motor 602 drives the balance plate 501 to rotate, causing one side of the guide plate 504 to tilt downward, which helps to clean the impurities on the surface of the receiving plate 503.

[0036] Combining the first and second embodiments, it can be known that the initial limiting is achieved by multiple sets of bolts and bosses in conjunction with the forklift wheel rim holes, the rubber sleeve of the side bracket 104 provides balanced support, the semi-circular arc frame 402 and the extended arc arm 406 form an embracing clamp to enhance stability, and the anti-slip rubber sleeve reduces friction damage; at the same time, the welding lifting frame 2 realizes multi-point coordinated welding to improve efficiency and quality, and the welding process is from bottom to top to avoid contaminating the forklift wheel rim.

[0037] The semicircular arc frame 402 can rotate the forklift wheel rim to facilitate double-sided welding. In addition, the slag collection adjustment column 6, the slag collection movable component 5 and the suction ring 505 cooperate to guide the slag, splashes, etc. to fall on the slidable receiving plate 503, and the balance plate 501 rotates to adjust the angle of the guide plate 504 to facilitate the cleaning of impurities, thereby achieving effective slag collection and cleaning.
