The counterweight device of engineering machinery equipment is usually installed at the tail of the equipment. By controlling its weight, the whole machine can meet the required tipping load, thereby achieving the stability requirements of the whole machine. Most of the existing counterweight assembly automation applications are limited to automatic transportation of large loads and long distances. The existing technology of truss handling devices has a structure with support beams and walking beams to build a truss, which is connected by a variety of transmission mechanisms such as gear racks, lead screws, and guide rails. It uses a motor with a reducer to provide power, and is equipped with a suitable clamp to achieve automatic transportation of counterweights.

[0003] At present, most of the automated applications of loader counterweights in the industry are concentrated in the handling link, and it is impossible to achieve full-process automation of the entire assembly process of handling, correcting, and tightening the counterweights, which greatly limits the improvement of the assembly automation process level.

[0037] The lifting mechanism 38 includes a lifting main frame 34, a servo motor II 33 and a lifting platform. The lifting main frame 34 adopts a gantry structure and is symmetrically arranged.

[0038] like Figure 8 As shown, the left side lifting and correction component 39 includes a left lifting frame 391, on which a left movable frame 394 and a left straightening component 392 are provided. The left straightening component 392 adopts a straightening cylinder to straighten the counterweight 51. The left movable frame 394 is driven by a left return cylinder 395. Two left return cylinders 395 are arranged opposite to each other on both sides of the left lifting frame 391. A baffle is provided on the left movable frame 394. The two left return cylinders 395 realize the movement of the left movable frame 394 by pushing the baffle.

The left inclined plane correction frame 396 and the left floating lifting block 393 are both slidably arranged on the left movable frame 394.

[0039] like Fig. 9As shown, the right lifting and correction assembly 310 includes a right lifting frame 3101, on which a right moving frame 3104 and a right straightening assembly 3106 are arranged. The right straightening assembly 3106 also uses a straightening cylinder to straighten the counterweight 51. The right moving frame 3104 is driven by a right return cylinder 3103.

The counterweight 51 can be lifted and corrected precisely to ensure the accurate position before assembly.

[0040] The left-side lifting and correction assembly and the right-side lifting and correction assembly are installed on the inner side of the gantry lifting main frame 34 through a slide rail structure. While lifting the counterweight 51, the left straightening assembly 392 and the right straightening assembly 3106 are used to cooperate with the movement of the left movable frame 394 and the right movable frame 3104 to achieve lateral position correction of the counterweight 51. The left inclined plane correction frame 396 and the right inclined plane correction frame are used to cooperate with the movement of the left floating lifting block 393 and the right floating lifting block 3105 to achieve front and rear position correction of the counterweight 51.

[0041] like Figure 7 As shown, the tightening mechanism 4 includes a tightening frame 45, and the tightening frame 45 is slidably provided with a tightening unit 43 through a tightening sliding mechanism 35. The tightening unit 43 adopts a vertical bolt tightening machine, and hole-aligning motors 42 are provided on both sides of the tightening unit 43. The hole-aligning motor 42 on one side is the power for the tightening unit 43 to move up and down; the hole-aligning motor 42 on the other side is the power for the tightening unit 43 to move left and right.

[0042] The tightening mechanism 4 is provided with two tightening units 43, which can provide multi-point tightening to ensure the uniformity and reliability of tightening; the tightening mechanism 4 is provided with a driving mechanism 41 on both sides, and the driving mechanism 41 includes a driving motor, a gear, a rack, a slider and a slide rail; the driving motor, the gear, the rack, the slider and the slide rail cooperate to enable the tightening mechanism 4 to move on the rotary lifting mechanism 3. The tightening mechanism 4 is provided with a visual recognition system 44, which can automatically identify the position and posture of the counterweight 51 pieces, thereby improving the intelligent level and accuracy of assembly. In terms of tightening, the visual adaptive positioning technology is used to adopt a floating camera position to solve the problem of poor product positioning. Through the ranging laser feedback during the assembly process, the best camera position is automatically found to ensure that the bolt center recognition accuracy is 0.1mm. This technology solves the problem of floating changes in the camera position caused by the stop error of the assembly line. The visual recognition system 44 is a prior art and will not be described here.

[0043] like Figure 1 and Fig.10 As shown, the platform is equipped with a transfer mechanism 5, which includes a heavy-duty AGV transfer vehicle 52. The heavy-duty AGV transfer vehicle 52 can realize the automatic transfer of the counterweight 51. The electrical control cabinet 31 of the platform controls the servo motor I22, the servo motor II33, the tightening sliding mechanism 35, the correction sliding mechanism 311, the left return cylinder 395, the right return cylinder 3103, and the left and right straightening cylinders. The truss mechanism 1 adopts a main control center, and four substations distribute the control of multiple servo motors, pneumatic units, tightening units 43 and visual recognition guidance systems. The architecture adopts a bus layout, and information is exchanged and interconnected efficiently. The servo actuator is configured using the Siemens PN bus, and the wiring is simple and efficient. At the same time, the motion parameters, motor status, and mechanism position are obtained in real time, and the control is more flexible and accurate.

[0044] The rest is the same as Example 1.

[0045] The principle of the present invention is that the heavy-load AGV automatic transfer vehicle uses the magnetic navigation technology in the prior art to automatically transport the counterweight 51 to a designated position on one side of the support column 13. Press the start button on the control panel, and under the drive of the lifting mechanism 38, the left lifting correction component 39 and the right lifting correction component 310 connected to both sides of the rotary lifting mechanism 3 are vertically moved to the preset position below the counterweight 51 through the slide rail and the slider along the rotary lifting mechanism 3, and the counterweight 51 placed on the heavy-load AGV transfer vehicle 52 is lifted to the set height, and the heavy-load AGV automatic transfer mechanism 5 returns along the predetermined route. Then, the left straightening component 392 and the right straightening component 3106 cooperate with the movement of the left moving frame 394 and the right moving frame 3104 to realize the lateral position correction of the counterweight 51, and the left inclined plane correction frame 396 and the right inclined plane correction frame 3102 cooperate with the movement of the left floating lifting block 393 and the right floating lifting block 3105 to realize the front and rear position correction of the counterweight 51.

[0046] After the posture adjustment of the counterweight 51 on the truss mechanism 1 is completed, the end beam mechanism 2 installed on the upper part of the truss mechanism 1 is guided by the slide rail slider and driven by the gear rack, driven by the servo motor I 22, to achieve the lateral movement of the heavy-loaded end beam mechanism 2 along the truss mechanism 1. After moving to the specified position, the rotary lifting mechanism 3 connected to the end beam mechanism 2 through the slide rail slider uses the gear rack transmission and driven by the servo motor II 33 to achieve the longitudinal movement of the lifting mechanism 38 along the end beam mechanism 2, wherein the rotary lifting mechanism 3 adopts a two-layer design, and the two layers are connected by the rotary support assembly 37. The measurement of the double-sided laser sensor is used to achieve the posture adjustment of the counterweight 51 to adapt to the frame position. After the posture adjustment is completed, the whole moves along the X-axis close to the rear frame. After reaching the set position, the vertical bolts and nuts are manually pre-tightened. The tightening mechanism 4 is connected to the rear of the rotary lifting mechanism 3 through a slide rail slider. The tightening mechanism 4 is driven by a gear rack and pinion and driven by a hole-matching motor 42 to realize the vertical movement of the tightening unit along the rotary lifting mechanism 3. The positioning is performed by a visual camera to finally realize the automatic tightening of the opposite surface bolts and complete the automatic assembly and tightening of the counterweight 51.

[0047] The present invention completes the posture adjustment of the counterweight 51 on the truss through the steps of slope positioning - leveling measurement - centering positioning - torque clamping, and completes the posture adjustment of the counterweight 51 to adapt to the position of the frame through the steps of frame deflection positioning - frame center positioning - frame tilt leveling - fitting and approaching, and through the above multiple adjustments, the system finally realizes fully automatic hole assembly according to the laser measurement results.

[0048] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
