Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
Example one
Referring to fig. 1 to 5, a groove body straight seam welding tool includes a workbench 1, a first cylinder 2, a second cylinder 3, and an internal expanding structure 4, wherein a groove body 100 is reversely buckled at the periphery of the internal expanding structure 4 with a downward opening.
The internal distraction structure 4 is arranged on the workbench 1 and comprises a fixed seat 41, a support 42 and a distraction assembly 43 for actuating the support 42. Wherein the fixing seat 41 is fixedly arranged on the workbench 1, is of a hollow columnar structure, and has openings at the upper end and the lower end. The supporting member 42 is disposed at the periphery of the fixing base 41 and can move close to or away from the fixing base 41. In the present embodiment, the cross section of the fixing seat 41 is a diamond shape, and the internal expanding structure 4 includes four supporting members 42, and each supporting member 42 corresponds to one side surface of the fixing seat 41.
The supporting member 42 is a triangular prism having three sides, i.e., a first side 421 facing the fixing base 41 and two second sides 422 adjacent to the first side 421. The two second side surfaces 422 are perpendicular to each other, the intersection of the two second side surfaces 422 is far away from the fixed seat 41, and the intersection of the two second side surfaces 422 is in smooth transition. The respective second side surfaces 422 of the adjacent two supporting members 42 are located on the same plane, so that the four supporting members 42 form a rectangular parallelepiped as a whole.
The distractor assembly 43 includes a wedge 431 centrally located within the fixed base 41, a driving mechanism 432 for driving the wedge 431 in an ascending and descending motion, a push rod 433 disposed between the wedge 431 and the supporting member 42, a restoring mechanism 434 disposed between the fixed base 41 and the supporting member 42, and a guide mechanism 435.
The wedge 431 has a diamond-shaped cross section, four side surfaces of the wedge 431 are gradually inclined toward the middle from top to bottom, and the driving mechanism 432 is disposed above the wedge 431. In this embodiment, the driving mechanism 432 is a cylinder, and an output shaft 4321 of the cylinder is opposite to the wedge 431 and can push the wedge 431 to move downwards. The driving mechanism 432 may also be any other conventional technique that can push the wedge 431 to move linearly. A cover plate 44 is disposed above the fixing base 41, and the driving mechanism 432 is connected and fixed with the cover plate 44.
Alternatively, the driving mechanism 432 may be disposed below the wedge 431, and four sides of the wedge 431 may be inclined gradually from bottom to top toward the center.
Each push rod 433 is horizontally arranged, one end of each push rod 433 abuts against the side surface of the wedge 431, the other end of each push rod penetrates through the fixed seat 41 and then is connected with the first side surface 421 of the corresponding supporting piece 42, the fixed seat 41 can limit the push rods 433 in the vertical direction so that the push rods 433 can only move in the horizontal direction, and the extending direction of each push rod 433 is perpendicular to the first side surface 421 of the corresponding supporting piece 42. Thus, when the wedge 431 moves downward under the driving of the driving mechanism 432, the push rod 433 is pushed in a direction away from the wedge 431 due to the inclined surface of the wedge 431, thereby pushing the supporting member 42 in a direction away from the fixed seat 41. The four supporting members 42 are also kept as a whole as a rectangular parallelepiped in the pushing-out process.
The restoring mechanism 434 includes a spring 4341 and a spring seat 4342, and the spring seat 4342 is connected to the support 42 through the fixed seat 41. One end of the spring seat 4342 located in the fixed seat 41 has an end portion with an increased diameter, and both ends of the spring 4341 abut against the end portion of the spring seat 4342 and the fixed seat 41, respectively.
The guide mechanism 435 includes a slide rail 4351 and a corresponding slide block 4352 respectively located on the top and bottom surfaces of each support member 42, and the slide block 4352 is slidably engaged with the slide rail 4351. The sliding rail 4351 is fixed to the supporting member 42, the top sliding block 4352 is fixed to the cover 44, and the bottom sliding block 4352 is fixed to the worktable 1. Thus, the guide mechanism 435 may function to guide and reduce friction when the support member 42 is actuated.
The internal expanding structure 4 is adapted to a rectangular groove (the cross section of the groove 100 is rectangular).
The tank 100 includes four tank sides 101 and four corresponding flanges 102, and the tank sides 101 and the flanges 102 are approximately perpendicular. The periphery of the inner expanding structure 4 on the workbench 1 is provided with a positioning pin 11 for matching with a positioning hole on the flange 102 of the tank body 100.
The first air cylinders 2 comprise four air cylinders which are arranged around the internal expanding structure 4 and correspond to the middle positions of four side surfaces of the periphery of the internal expanding structure 4 respectively, the output ends of the first air cylinders 2 are provided with first pressing blocks 21, the first air cylinders 2 are arranged in a manner of inclining to the vertical direction, the output ends of the first air cylinders are inclined, and downward inclined force can be applied to the groove body 100.
The second cylinders 3 are eight and arranged around the internal expanding structure 4, and correspond to the positions, close to the intersection, of the two second side surfaces 422 of the supporting piece 42, respectively, and the output end of the second cylinder 3 is provided with a second pressing block 31, so that the second pressing block can correspond to and press the intersection (the bent position of the side surface of the tank 100) of the two adjacent tank side surfaces 101 of the tank 100.
When welding is needed, firstly, the groove body 100 is reversely buckled on the internal expanding structure 4, the driving mechanism 432 is started, the wedge block 431 is driven to move, the push rod 433 pushes the supporting piece 42 to move outwards for a certain distance, the shape of the supporting piece 42 after moving outwards and expanding is matched with the shape of the groove body 100 (the four supporting pieces 42 are simultaneously used for expanding outwards), the distance can be preset, and at the moment, the spring 4341 is stretched; then, the positioning hole on the flanging 102 of the slot body 100 is buckled into the positioning pin 11; then, each first cylinder 2 is actuated to press against the tank body 100, so that the flange 102 of the tank body 100 is pressed against the side surface 101 of the tank body; then, the second cylinders 3 act to press the side faces 101 of the tank body at the bent positions, so that the arc transition at the intersection of the side faces of the tank body 100 is completely wrapped on the supporting piece 42 of the internal expanding structure 4, thereby completing clamping of the tank body 100.
After clamping is completed, manual point grabbing can be performed, robot welding can also be performed, and efficiency is improved. When the welding is completed, the driving mechanism 432 stops, and the support member 42 is restored by the restoring force of the spring 4341.
Due to the fact that the groove body 100 is attached to the internal expanding structure 4, four welding seams are spliced by clamping on one welding tool at one time, and the consistency of the four welding seams between the side faces 101 of the groove body can be improved.
Example two
Referring to fig. 6 and 7, in the present embodiment, the difference from the first embodiment is that the cross section of the slot 100 is square, the cross sections of the fixing seat 41 and the wedge 431 are both square (when four corners of the diamond are equal, the square is formed), and the internal expanding structure 4 is adapted to the square slot.
