Detailed Description
The present disclosure will be described in further detail with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limitations of the present disclosure. It should be further noted that, for the convenience of description, only the portions relevant to the present disclosure are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Referring to the attached drawing 1, the disclosure provides a welding production system of a cone machine, which comprises a welding robot 1, a position changing machine 2, a submerged arc welding machine 3, a movable cone welding support platform 4 and a welding repair device 5 of a crusher adjusting threaded sleeve. The welding robot is used for welding the movable cone assembly, the adjusting threaded sleeve and the machine base assembly 6.
Referring to fig. 2, the position changing machine 2 includes a position changing base 21, a position changing table 22, a position changing rotating shaft 23 and a driving motor. The displacement table 22 is rotatably connected with the displacement base 21 through the displacement rotating shaft 23. The deflection table 22 is provided with an interface for connection with the base assembly 6. The driving motor drives the shifting table 22 to rotate around the shifting rotating shaft 23 so as to adjust the posture of the machine base assembly 6.
Referring to fig. 2, the welding robot 1 and the submerged arc welding machine 3 are located at different spatial positions relative to the positioner 2, and preferably the welding robot 1 and the submerged arc welding machine 3 are distributed on both sides of the displacement table 22. In this case, the welding robot 1 and the submerged arc welding machine 3 can avoid mutual interference as much as possible. However, since the welding robot 1 and the submerged arc welding machine 3 are spatially separated from each other, the machining position of the base assembly 6 required by the welding robot 1 and the submerged arc welding machine 3 is not matched, and at this time, the base assembly 6 needs to be adjusted by the positioner 2 so that the base assembly 6 approaches the submerged arc welding machine 3 or approaches the welding robot 1. Meanwhile, it should be noted that, because the submerged arc welding machine 3 and the welding robot 1 are different in structure and the required postures of the machine base assembly 6 in the machining process are different, in order to facilitate automatic machining, the positioner 2 is required to automatically adjust the machine base assembly 6 to the welding postures required by the welding robot 1 and the submerged arc welding machine 3. The position changing table 22 rotates around the position changing rotating shaft 23 to adjust the posture of the machine base assembly 6, and meanwhile the purpose of adjusting is achieved.
Since the outer side of the base assembly 6 needs to be welded, no matter the welding robot 1 or the submerged arc welding machine 3 can only approach the base assembly 6 from one side of the base assembly 6, and the welding robot 1 or the submerged arc welding machine 3 has difficulty in processing the side of the base assembly 6 away from the welding robot 1 or the submerged arc welding machine 3. Meanwhile, because the submerged arc welding machine 3 only has 1 degree of freedom of movement, in order to complete the complete welding of the outer side surface of the machine base assembly 6, the positioner 2 is required to provide one degree of freedom of rotation to make up for the problem that the submerged arc welding machine 3 has insufficient degree of freedom. Therefore, the shifting table 22 of the present disclosure further includes a shifting receiving plate 221 and a rotating base 223 disposed on the upper side of the shifting receiving plate 221, the rotating base 223 is provided with an interface connected with the base assembly 6, and the rotating base 223 is adapted to drive the base assembly 6 to rotate around the axis of the rotating base 223. The rotary base 223 makes up for the lack of freedom of the submerged arc welding machine 3, and can expose the processing position of the base assembly 6 in the working range of the welding robot 1. The indexing table 22 includes, but is not limited to, square and circular. After the rotating base 223 is installed on the base assembly 6, the gravity center of the rotating base 223, the gravity center of the base assembly 6 and the gravity center of the displacement table 22 are on the same straight line, so that the displacement table 22 is prevented from generating excessive bending deformation due to displacement. The displacement table 22 further comprises a bearing plate mounting part 222, the bearing plate mounting part 222 is also arranged at the center of gravity of the displacement bearing plate 221, the bearing plate mounting part 222 extends outwards from the bottom surface of the displacement bearing plate 221, and one end, far away from the bottom surface of the bearing plate, of the bearing plate mounting part 222 is used for being hinged to the displacement rotating shaft 23. Preferably, the connecting line of the center of gravity of the rotating base 223, the center of gravity of the base assembly 6 and the center of gravity of the shifting table 22 intersects with the axis of the shifting rotary shaft 23.
Referring to fig. 4, the displacement base 21 includes a base body 211 and a displacement mounting portion 212 located at an upper portion of the base body 211. The swing angle of the position changing table 22 directly influences the flexibility of the position changing machine 2. If the displacement mounting portion 212 is provided inside any one side surface of the base body 211, the side surface of the base body 211 restricts the swing space of the displacement table 22. Therefore, it is necessary to separate the displacement mounting portion 212 from any wall surface of the base body 211 to enlarge the swing space of the displacement table 22. The displacement mounting part 212 of the present disclosure extends outward from a sidewall of the base body 211, and an upper side surface of the displacement mounting part 212 is preferably flush with an upper side surface of the base body 211. Thereby ensuring the upward turning angle of the position changing table 22 and the connection strength of the position changing installation part 212 and the base body 211. The end of the displacement mounting part 212 far away from the base body 211 is provided with a shaft hole for mounting the displacement rotating shaft 23. The axis forming the shaft hole is disposed at a distance from the side wall. It is noted that the distance between the axis of the axial hole and the side wall should be not more than twice the thickness of the deflection mounting portion 212 in the vertical direction. So as to avoid the destructive deformation of the displacement mounting part 212 caused by bending moment.
In a further embodiment, the indexing base 21 further comprises a base 213, and the base 213 is disposed at the bottom of the base body 211. The axial line of the shaft hole is arranged at a distance from the side wall. When the gravity of the base assembly 6 is greater than the gravity of the base body 211, and the gravity of the base assembly 6 and the gravity of the base body 211 are located on two sides of the fulcrum of the positioner 2 and the ground, the positioner 2 is easy to turn on the side. Therefore, a base seat 213 larger than the base body 211 needs to be provided. Specifically, the base 213 extends outward along the side wall of the base body 211 provided with the displacement mounting portion 212. And the distance between the outer end of the base 213 and the side wall is greater than the distance between the axis of the shaft hole and the side wall, so that the ground can generate enough rollover moment on the base 213 to balance the generation of the engine base assembly 6. Further, the distance between the outer end of the base 213 and the sidewall is larger than the distance between the center of gravity of the base assembly 6 and the sidewall when the position changing table 22 is at any position. Meanwhile, in order to ensure that the base 213 has a certain strength and avoid the base 213 from being deformed destructively due to the overturning moment generated by the base assembly 6, the base 213 is made of metal and/or alloy.
