Description

Technical Field

[0001] The invention belongs to the field of vehicle processing and manufacturing, and relates to a two-sided hanging component division turntable. Background Art

[0002] The inner panel of the rear door frame of Jetta in the welding workshop is manually loaded. The workpiece is light, with a single workpiece weighing less than 2 kilograms. The personnel have to walk a short distance to load the workpiece, and they need to wait every time they load the workpiece. They work 8 hours a day, and 4 hours are wasted waiting. In order to avoid wasting time, the manual loading is changed to automatic loading by robots, which can optimize one operator. The industry has traditionally adopted a visual system for automatic loading by robots. There are a total of 2 such workstations in the workshop. The visual system requires about 4 million yuan, which is costly. In addition, since the workpiece has 2 flanges in the X and Y directions, and the surface of the workpiece is uneven, when the workpieces are accumulated to 5, the fifth workpiece and the bottom workpiece differ by 7 mm in the X and Y directions, and there is rotation in these two directions. The robot cannot grasp it using a fixed trajectory, which has great limitations. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a double-sided hanging component turntable, which adopts the hanging method to load components. When manual loading occurs, it does not affect the normal picking up of components by the robot on the other side, thus saving manual waiting time, accurately positioning the workpiece, and greatly improving work efficiency.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a two-sided hanging component turntable, including a hanging component bracket, a magnetic suction component, a rotating shaft, a motor and a turntable bracket. The hanging component bracket is an axisymmetric structure as a whole, and is composed of a hanging plate, an upper crossbeam and a lower crossbeam. There are at least two upper crossbeams, which cross the upper part of the hanging plate and are fixed on the hanging plate. There are at least two lower crossbeams, which cross the lower part of the hanging plate and are fixed on the hanging plate. This installation method can ensure the symmetry of the hanging component bracket structure and ensure that the upper crossbeams have the same position height, so that when the equipment is running, the hanging component bracket rotates and turns over, and the robot can grab the workpiece using a fixed trajectory. The lower crossbeam is installed with a magnetic suction component, which can position the workpiece in the Z direction. The rotating shaft is fixed to the bottom of the hanging plate and driven by a motor, and the motor is fixed to the turntable bracket. The motor is the power source of the two-sided hanging component turntable, driving the rotating shaft to rotate, thereby driving the workpiece on the hanging component bracket to rotate and turn over.

[0005] Preferably, U-shaped parts are installed on both sides of the top of the upper crossbeam on the hanger plate, and the U-shaped parts are used to position the workpiece in the X direction, that is, to prevent the workpiece from sliding off the upper crossbeam.

[0006] Preferably, a wear-resistant strip is installed on the top of the U-shaped member to prevent the U-shaped member from being worn by the workpiece.

[0007] Preferably, the material used for the wear-resistant strip is Cr12MoV, the hardness can reach HRC58, and the hardness index can reach the highest hardness index of domestic materials.

[0008] Preferably, the hanger plate adopts a square frame iron plate, the frame reduces weight and has low cost.

[0009] Preferably, the rotating shaft is welded by a vertical shaft and a connecting block, the connecting block is fixed to the bottom middle of the hanging plate by bolts, and the lower end of the vertical shaft is rigidly connected to the motor. The connecting block makes the connection between the hanging plate and the vertical shaft more stable.

[0010] Preferably, a bearing is installed on the vertical shaft, and the outer ring of the bearing is fixed to the turntable bracket through a support plate. The outer ring of the bearing is fixed, and the inner ring of the bearing is fixed to the vertical shaft through a key, and the inner ring and the vertical shaft rotate synchronously.

[0011] Preferably, the bearing model is 30309, and the maximum bearing force that can be sustained is 4 tons.

[0012] Preferably, the turntable bracket is a frame structure welded from 60 square steel, which is lightweight and low-cost while meeting the supporting force requirements.

[0013] The two-sided hanging parts dividing turntable provided by the present invention has the following beneficial effects:

[0014] 1. During the manual loading process, the workpiece can be accurately positioned in the X, Y, and Z directions to prevent the workpiece from shaking and sliding.

[0015] 2. The use of hanging parts can enable the robot to grasp the workpiece using a fixed trajectory.

[0037] like Figure 1 As shown, the present invention provides a two-sided hanging component turntable, including a hanging component bracket 1, a magnetic attraction component 2, a rotating shaft 3, a motor 4 and a turntable bracket 5.

[0038] like Figure 1 and Figure 2 As shown, the hanger bracket 1 is an axisymmetric structure as a whole, and is composed of a hanger plate 11 , an upper crossbeam 12 and a lower crossbeam 13 .

[0039] The hanging plate 11 is made of a square frame iron plate or other metal materials.

[0040] At least two upper cross beams 12 are provided. In this embodiment, two upper cross beams 12 are provided. The two upper cross beams 12 are parallel to each other, both cross the upper part of the hanger plate 11 and are fixed on the hanger plate 11. The upper cross beam 12 and the hanger plate 11 can be fixed by welding. The top of the upper cross beam 12 is installed with U-shaped parts 14 on both sides of the hanger plate 11. The U-shaped parts 14 are arranged along the direction of the upper cross beam 12 and are fixed to the upper cross beam 12 by bolts. The top of the U-shaped part 14 is installed with a wear-resistant strip 15, which can be fixed by gluing. The material used is Cr12MoV, and the hardness can reach HRC58. The hardness index can reach the highest hardness index of domestic materials.

[0041] At least two lower cross beams 13 are provided. In this embodiment, two lower cross beams 13 are provided. The two lower cross beams 13 are parallel to each other, both cross the lower part of the hanger plate 11 and are fixed on the hanger plate 11. The lower cross beam 13 and the hanger plate 11 can be fixed by welding. In this preferred embodiment, the lower cross beam 13 is a hollow steel pipe, and the top of the lower cross beam 13 is installed on both sides of the hanger plate 11. The magnetic attraction component 2 is welded and fixed to the lower cross beam 13.

[0042] In summary, there are four U-shaped parts 14, which can position the workpiece hung thereon in the X direction. There are four magnetic suction components 2, which can generate suction on the workpiece hung above it and position the workpiece in the Z direction. In addition, during use, the workpiece is positioned in the Y direction in cooperation with the side top cylinder top member arranged outside the turntable. As described above, precise positioning of the workpiece is achieved. In another embodiment, each upper crossbeam 12 can be divided into two, and the two parts are respectively fixed to the two sides of the hanger plate 11 by bolts, so as to ensure that the two parts of the upper crossbeam 12 have the same position height. Similarly, each lower crossbeam 13 can be divided into two, and the two parts are respectively fixed to the two sides of the hanger plate 11 by bolts, so as to ensure that the two parts of the lower crossbeam 13 have the same position height.

[0043] like Figure 1 and Figure 3 As shown, the rotating shaft 3 is installed at the bottom of the hanging plate 11 and driven by the motor 4, which is fixed on the turntable bracket 5. The rotating shaft 3 has a certain toughness, which satisfies the quenching and tempering treatment. As for the specific installation structure, in this preferred embodiment, the rotating shaft 3 is welded by a vertical shaft 31 and a connecting block 32. The connecting block 32 is in the shape of a short cylindrical block with a plurality of bolt holes. The lower end of the vertical shaft 31 is rigidly connected to the motor 4. Figure 1, a bearing 33 is installed on the vertical shaft 31, and the outer ring of the bearing 33 is fixed to the turntable bracket 5 through a support plate 34. Specifically, the inner ring of the bearing 33 is fixed to the vertical shaft 31 by a key connection, and the inner ring and the vertical shaft 31 can rotate synchronously; the outer ring of the bearing 33 is fixed to the support plate 34 by bolts, and the support plate 34 is fixed to the turntable bracket 5 by bolts, and the outer ring, the support plate 34 and the turntable bracket 5 are fixed. In this preferred embodiment, the model of the bearing 33 is 30309, and the maximum bearing force that can be borne is 4 tons, which is fully capable of balancing the force required by the on-site load.

[0044] The turntable bracket 5 is a frame structure welded from 60 square steel, which is lightweight and low in cost while meeting the supporting force. The turntable bracket 5 can also be made of iron or other materials, which are not specifically limited here.

[0045] On-site requirements in actual application: 1. Employees should not affect production when loading workpieces; 2. Employees should load 120 workpieces at a time and 4-5 times a day.

[0046] The two-sided hanging parts dividing turntable provided by the present invention is used to manually hang the workpiece on the upper crossbeam 12 of the hanging parts bracket 1, and the bottom of the workpiece is positioned by the magnetic suction component 2. The manual loading does not affect the normal grasping of the robot on the other side. 60 workpieces are loaded on one side, and every 5 workpieces form a group of workpieces with two flanges mutually contained. The 6th workpiece will be separated from the previous group of workpieces. The internal grouping of 60 workpieces is realized by controlling the distance size of the hanging parts bracket. This can reduce the size deviation of the 60 workpieces caused by the flanges after the workpieces are mutually contained, thereby realizing the first division. In order to realize the grasping of a single workpiece, a large number of experiments have been conducted to realize the secondary separation of the workpiece by using a magnetic cylinder robot to search for instruction suction parts. After the workpiece is separated, the U-shaped part positions the workpiece in the X direction, the magnetic suction component positions the workpiece in the Z direction, and the side top cylinder top part is added to position the workpiece in the Y direction. During the operation of the equipment, when it is necessary to turn over, the motor 4 drives the rotating shaft 3 to rotate, and synchronously drives the hanging parts bracket 1 and the workpiece thereon to rotate and turn over, and then carry out subsequent manual loading and robot picking. The whole process saves time and effort and greatly improves work efficiency.

[0047] It should be noted that the above description is only a preferred embodiment of the present invention and cannot limit the scope of implementation of the present invention. Therefore, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
