Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shell welding devices, and particularly relates to a welding positioning device for shell closing. BACKGROUND

[0002] The high-altitude counterweight box is a key component in engineering machinery (such as cranes, tower cranes, aerial work platforms, etc.) for balancing the load and ensuring the stability of the work. As the core balancing component of modern engineering machinery, the development of the high-altitude counterweight box has always revolved around the dual requirements of safety and efficiency. Early counterweight boxes mostly used fixed cast iron blocks to balance the arm load through physical weight. However, the use of cast iron blocks has the problems of inconvenient production and high production cost.

[0003] In order to save production costs, the existing technology usually uses the method of pouring cement inside the shell. During production, only a shell with an opening needs to be produced. After the shell is produced, cement is poured into the shell through the opening. After the cement is filled, the opening on the shell is welded to form a high-altitude counterweight box. By separately producing the shell, the purpose of saving costs and facilitating production is achieved. However, in order to improve the strength of the shell, a reinforcing inner liner needs to be provided inside the shell. After pouring cement inside the shell, the overall strength of the high-altitude counterweight box can be improved through the welding of the shell and the reinforcing inner liner.

[0004] When producing a shell with a reinforcing inner liner, in order to facilitate the installation and welding of the reinforcing inner liner, two arc-shaped shells with openings need to be manufactured during production. Then, a reinforcing inner liner is welded inside each arc-shaped shell. After the reinforcing inner liners inside the two arc-shaped shells are welded, the arc-shaped shells with reinforcing inner liners are welded together through closing to form a counterweight box shell with a reinforcing inner liner.

[0005] During the welding of the reinforcing inner liner, the arc-shaped shell needs to be placed on the welding table with the opening of the arc-shaped shell facing upwards. Then, the reinforcing inner liner is placed inside the arc-shaped shell. The position of the reinforcing inner liner needs to be adjusted multiple times by the worker to make the edges of the reinforcing inner liner parallel to the edges of the arc-shaped shell. Finally, the reinforcing inner liner is fixed on the arc-shaped shell through spot welding. Since the cross section of the reinforcing inner liner is smaller than that of the arc-shaped shell, in order to ensure the straightness of the arc-shaped shell and the reinforcing inner liner, the position of the reinforcing inner liner needs to be adjusted multiple times by the worker before welding, thereby causing the production efficiency of the entire shell to decrease.

DETAILED DESCRIPTION

[0028] The following will be described in detail below with reference to the accompanying drawings. Figures 1-9 The present application will be further described in detail.

[0029] Embodiment I The embodiment of the application discloses a welding positioning device for shell assembling, which comprises a bottom plate 1 arranged on the ground, a vertical plate 11 fixed on the bottom plate 1, a through hole 12 arranged on the vertical plate 11, and a positioning plate 13 fixedly installed on the bottom plate 1. When a reinforced inner container 01 is placed in the through hole 12, the reinforced inner container 01 abuts against the positioning plate 13, and a fixing assembly 2 is arranged on the positioning plate 13 and used for fixing the reinforced inner container 01 on the positioning plate 13. In addition, a calibration assembly 4 is slidably connected to the bottom plate 1, an arc-shaped shell 02 is placed on the calibration assembly 4, and the arc-shaped shell 02 arranged on the calibration assembly 4 is arranged with an opening facing the positioning plate 13. The arc-shaped shell 02 is placed on the calibration assembly 4, and the arc-shaped shell 02 is moved by moving the calibration assembly 4, so that the arc-shaped shell 02 is covered on the fixed reinforced inner container 01. Due to the arrangement of the calibration assembly 4 and the positioning plate 13, the edge of the arc-shaped shell 02 covered on the reinforced inner container 01 is arranged in parallel with the edge of the reinforced inner container 01. Finally, a worker fixes the reinforced inner container 01 on the arc-shaped shell 02 by spot welding. After the reinforced inner container 01 is welded in the two arc-shaped shells 02, the arc-shaped shells 02 are welded into a counterweight shell by assembling.

[0030] In the embodiment, the fixing assembly 2 is a fixing bolt 21, a plurality of mounting holes 23 are formed in the positioning plate 13, a plurality of fixing holes 22 are formed in the reinforced inner container 01, and threads are arranged in the fixing holes 22. The plurality of fixing holes 22 correspond to the plurality of mounting holes 23 one by one. When the reinforced inner container 01 is fixed, a crane lifts the reinforced inner container 01 first, and then the reinforced inner container 01 is moved to the upper side of the bottom plate 1 by the crane. A worker adjusts the position of the reinforced inner container 01, so that the fixing holes 22 on the reinforced inner container 01 correspond to the mounting holes 23. At this time, another worker inserts the fixing bolt 21 into the mounting hole 23 and rotates the fixing bolt 21, so that the fixing bolt 21 is threadedly connected with the fixing hole 22. Since the mounting hole 23 and the fixing hole 22 are arranged in plurality, the reinforced inner container 01 is fixed on the positioning plate 13 by the plurality of fixing bolts 21. In the embodiment, the mounting hole 23 and the fixing hole 22 are arranged in four, and the fixing bolt 21 is also arranged in four.

[0031] The proofreading assembly 4 comprises a sliding rail 41 fixed on the bottom plate 1, a supporting plate 42 slidingly connected to the sliding rail 41, a connecting plate 43 fixed on the supporting plate 42, and an abutting plate 44 fixed on the connecting plate 43, and the abutting plate 44 is provided with an arc surface 14, and the arc surface 14 on the abutting plate 44 is used to abut against the outer surface of the arc-shaped shell 02. In the embodiment, the upper and lower surfaces of the arc-shaped shell 02 are both arranged as horizontal surfaces, and the bottom surface of the arc-shaped shell 02 to be welded is placed on the supporting plate 42, and at the same time, the side surface of the arc-shaped shell 02 on the supporting plate 42 abuts against the arc surface 14 on the abutting plate 44. Then, the worker pushes the connecting plate 43 and the supporting plate 42 to move towards the reinforced inner container 01 fixed on the positioning plate 13. In the moving process of the supporting plate 42, the arc-shaped shell 02 is driven to move towards the reinforced inner container 01, and finally the arc-shaped shell 02 is sleeved on the reinforced inner container 01. When the arc-shaped shell 02 is completely covered on the reinforced inner container 01, the worker welds the reinforced inner container 01 on the arc-shaped shell 02 by spot welding.

[0032] A plurality of abutting plates 44 are arranged on the vertical plate 11, and the plurality of abutting plates 44 are uniformly and spacedly arranged along the circumferential direction of the through hole 12. When the arc-shaped shell 02 is completely covered on the reinforced inner container 01, the edge of the opening of the arc-shaped shell 02 abuts against the abutting plate 44. When the plurality of abutting plates 44 all abut against the edge of the opening of the arc-shaped shell 02, the edge of the arc-shaped shell 02 is arranged in parallel with the edge of the reinforced inner container 01.

[0033] In order to improve the connection strength of the reinforced inner container 01 and the arc-shaped shell 02, a clamping assembly 5 is arranged on the vertical plate 11. The clamping assembly 5 comprises a clamping frame 51 fixed on the vertical plate 11, a clamping air cylinder 52 fixed on the clamping frame 51, and a clamping plate 53 fixed on the piston rod of the clamping air cylinder 52. The clamping plate 53 is slidingly connected to the vertical plate 11. In the embodiment, two clamping assemblies 5 are arranged, and the two clamping assemblies 5 are arranged on the two sides of the arc-shaped shell 02. The two clamping air cylinders 52 drive the two clamping plates 53 to move simultaneously, and the two clamping plates 53 abut against the side surface of the arc-shaped shell 02, so that the clamping plate 53 pushes the inner wall of the arc-shaped shell 02 to abut against the reinforced inner container 01, thereby improving the stability of the arc-shaped shell 02 and facilitating the fixation of the reinforced inner container 01 on the arc-shaped shell 02.

[0034] The positioning plate 13 on the connecting plate 43 is provided with a plurality of positioning plates 13, which are uniformly and spacedly arranged along the vertical direction of the connecting plate 43, and the connecting plate 43 is arranged on both sides of the supporting plate 42. The connecting plate 43 on both sides is provided with a plurality of positioning plates 13, and each positioning plate 13 is provided with an arc surface 14. When the outer side surface of the arc-shaped shell 02 abuts against the plurality of arc surfaces 14, the position of the arc-shaped shell 02 is positioned. In the moving process of the supporting plate 42, the arc-shaped shell 02 can be covered on the fixed reinforced inner container 01.

[0035] In the embodiment, in order to reduce the weight of the slide rail 41 and the weight of the connecting plate 43, the weight-reducing holes are arranged on the slide rail 41 and the connecting plate 43.

[0036] The locking assembly (not shown in the figure) for fixing the position of the support plate 42 is arranged on the connecting plate 43, and the locking assembly comprises a locking sleeve fixed on the bottom plate 1 and a locking rod slidingly connected to the connecting plate 43. When the arc-shaped shell 02 is covered on the reinforced inner container 01, the locking rod is slid to be inserted into the locking sleeve, and then the position of the support plate 42 is limited, so that the clamping plate 53 pushes the side surface of the arc-shaped shell 02 to abut on the reinforced inner container 01.

[0037] The implementation principle of the welding positioning device for shell assembly in the embodiment is as follows: when the reinforced inner container 01 and the arc-shaped shell 02 are welded, the worker uses the crane to lift the reinforced inner container 01, and moves the reinforced inner container 01 to the upper side of the bottom plate 1 by the crane. One worker adjusts the position of the reinforced inner container 01, so that the fixing holes 22 on the reinforced inner container 01 correspond to the mounting holes 23. At this time, another worker inserts a plurality of fixing bolts 21 into the mounting holes 23 respectively, and rotates the plurality of fixing bolts 21 respectively, so that the fixing bolts 21 are threadedly connected with the fixing holes 22, and the reinforced inner container 01 is fixed on the positioning plate 13.

[0038] The worker uses the crane to hoist the arc-shaped shell 02 to the support plate 42, adjusts the position of the arc-shaped shell 02 on the support plate 42, so that the outer side surface of the arc-shaped shell 02 abuts on the plurality of arc-shaped surfaces 14 at the same time, the worker pushes the connecting plate 43 and the support plate 42 to move towards the reinforced inner container 01 fixed on the positioning plate 13. The support plate 42 moves in the process, which drives the arc-shaped shell 02 to move towards the reinforced inner container 01, and finally the arc-shaped shell 02 is covered on the reinforced inner container 01. When the arc-shaped shell 02 is completely covered on the reinforced inner container 01, the two clamping cylinders 52 drive the two clamping plates 53 to move at the same time, the two clamping plates 53 abut on the side surface of the arc-shaped shell 02, so that the clamping plate 53 pushes the inner wall of the arc-shaped shell 02 to abut on the reinforced inner container 01. Finally, the worker fixes the reinforced inner container 01 on the arc-shaped shell 02 by spot welding. Compared with the prior art, the position of the reinforced inner container 01 does not need to be adjusted for multiple times when the reinforced inner container 01 is welded, so that the welding efficiency of the reinforced inner container 01 can be improved.

[0039] Embodiment two The difference from the embodiment one is that the reinforced inner container 01 is fixed on the positioning plate 13, and the installation efficiency of the reinforced inner container 01 is improved.

[0040] The fixing assembly 2 comprises a first fixing rod 31 fixed on the positioning plate 13 and a plurality of second fixing rods 32, and the first fixing rod 31 and the second fixing rods 32 are provided with the pressing assemblies 7, and the pressing assemblies 7 are used for pressing the reinforced inner container 01 on the positioning plate 13.

[0041] The length of the first fixing rod 31 is greater than the length of the second fixing rod 32, the first fixing rod 31 and the second fixing rod 32 are provided as cylindrical rods, and the cross sections of the first fixing rod 31 and the second fixing rod 32 are the same as the cross section of the fixing hole 22, in the embodiment, three second fixing rods 32 are provided, one first fixing rod 31 is provided, and then four pressing assemblies 7 are provided, and the strength of the reinforced inner container 01 on the positioning plate 13 is improved under the action of the four pressing assemblies 7.

[0042] Since the length of the first fixing rod 31 is greater than the length of the second fixing rod 32, at this time, the crane moves the lifted reinforced inner container 01 above the base plate 1, adjusts the position of the reinforced inner container 01, so that the fixing hole 22 on the reinforced inner container 01 corresponds to the first fixing rod 31, and then the reinforced inner container 01 is arranged on the first fixing rod 31 through the fixing hole 22, the lifted reinforced inner container 01 is supported by the first fixing rod 31, and the staff can take down the reinforced inner container 01 from the crane; the remaining fixing holes 22 correspond to the plurality of second fixing rods 32 by rotating the reinforced inner container 01 on the first fixing rod 31, the reinforced inner container 01 is directly pushed to slide on the first fixing rod 31, and finally the plurality of second fixing rods 32 are arranged in the remaining fixing holes 22, so as to adjust the position of the reinforced inner container 01.

[0043] After the position of the reinforced inner container 01 is adjusted, the reinforced inner container 01 is pressed on the positioning plate 13 by the pressing assembly 7, and then the arc-shaped shell 02 is arranged on the reinforced inner container 01; the first fixing rod 31 and the second fixing rod 32 are provided with the mounting grooves 16, the pressing assembly 7 is arranged in the mounting groove 16, the pressing assembly 7 comprises a fixed block 71 arranged in the mounting groove 16, a moving block 72 slidably connected in the mounting groove 16, a pressing rod 73 hingedly connected to the moving block 72, and a connecting rod 74 hingedly connected to the pressing rod 73, and one end of the connecting rod 74 away from the pressing rod 73 is hingedly connected to the fixed block 71; in the embodiment, the moving block 72 is provided with a stop block 17, when the moving block 72 moves towards the fixed block 71, the pressing rod 73 is opened, and since the stop block 17 is arranged, the pressing rod 73 will finally abut against the stop block 17 and cannot continue to rotate outward, so that the moving block 72, the fixed block 71 and the pressing rod 73 are simultaneously moved towards the positioning plate 13, and one end of the expanded pressing rod 73 away from the moving block 72 abuts against the inner wall of the reinforced inner container 01.

[0044] The adjusting assembly 8 is arranged on the first fixed rod 31 and is used to adjust the position of the moving block 72. During the adjusting process, the pressing rod 73 can be turned out of the mounting groove 16, the pressing rod 73 turned out of the mounting groove 16 abuts against the stop block 17, then the adjusting assembly 8 moves the moving block 72, the fixed block 71 and the pressing rod 73 simultaneously towards the positioning plate 13, the end of the pressing rod 73 away from the moving block 72 abuts against the inner wall of the reinforced inner container 01, and finally the pressing rod 73 presses the reinforced inner container 01 against the positioning plate 13, so that the position of the reinforced inner container 01 is fixed.

[0045] The adjusting assembly 8 comprises an adjusting rod 81 slidably connected to the first fixed rod 31, an adjusting spring 82 sleeved on the adjusting rod 81 and a supporting spring 83 fixed to the first fixed rod 31. One end of the supporting spring 83 is fixed to the first fixed rod 31 and the other end is fixed to the fixed block 71. One end of the adjusting spring 82 is fixed to the fixed block 71 and the other end is fixed to the moving block 72. The adjusting spring 82 moves the moving block 72 away from the fixed block 71, so that the pressing rod 73 is in the mounting groove 16. The supporting spring 83 and the adjusting spring 82 are arranged on both sides of the fixed block 71. In this embodiment, the elastic force of the supporting spring 83 is greater than that of the adjusting spring 82.

[0046] One end of the adjusting rod 81 is rotationally connected to the moving block 72 and the other end extends out of the positioning plate 13 and is fixedly installed with a rotating ring 91. A limiting block 92 is fixedly installed on the adjusting rod 81. A sliding groove 9 is formed in the first fixed rod 31 and extends along the length direction of the first fixed rod 31. The limiting block 92 is slidably connected in the sliding groove 9.

[0047] When the pressing rod 73 needs to be opened, the staff directly pulls the adjusting rod 81 through the rotating ring 91. The adjusting rod 81 drives the moving block 72 to slide in the mounting groove 16. During the sliding process of the moving block 72 towards the fixed block 71, the elastic force of the supporting spring 83 is greater than that of the adjusting spring 82. At this time, the adjusting spring 82 is compressed and the elastic force of the supporting spring 83 remains unchanged. The pressing rod 73 rotates away from the mounting groove 16. When the pressing rod 73 abuts against the stop block 17, the pressing rod 73 cannot continue to rotate and the adjusting spring 82 cannot continue to be compressed. When the adjusting rod 81 continues to slide outwards, the limiting block 92 is separated from the sliding groove 9. The pressing rod 73 abuts against the reinforced inner container 01 and presses the reinforced inner container 01 against the positioning plate 13. Then the adjusting rod 81 is rotated, so that the limiting block 92 on the adjusting rod 81 abuts against the end face of the first fixed rod 31. The limiting block 92 and the sliding groove 9 are arranged in a staggered manner. The adjusting rod 81 cannot slide on the first fixed rod 31, so that the position of the adjusting rod 81 is fixed.

[0048] After the welding is completed, the adjusting rod 81 is reversely rotated, the limiting block 92 on the adjusting rod 81 corresponds to the sliding groove 9, then the supporting spring 83 and the adjusting spring 82 drive the moving block 72 and the fixed block 71 to reset, finally the pressing rod 73 is rotated into the mounting groove 16, so that the reinforced inner container 01 and the arc-shaped shell 02 after welding can be conveniently removed from the first fixed rod 31 and the second fixed rod 32.

[0049] In the embodiment, the pressing assembly 7 on the second fixed rod 32 has the same structure as the pressing structure on the first fixed rod 31, and the specific structure of the pressing assembly 7 on the second fixed rod 32 will not be described in detail. In the embodiment, two pressing rods 73 are arranged on each moving block 72, which can improve the fixing strength of the reinforced inner container 01.

[0050] An abutting surface 93 is arranged at the end of the pressing rod 73 away from the moving block 72, and the abutting surface 93 is arranged obliquely, so that when the pressing rod 73 abuts against the stop block 17, the pressing rod 73 cannot continue to rotate, and then the abutting surface 93 is parallel to the surface of the reinforced inner container 01. The fixed block 71, the moving block 72 and the adjusting spring 82 are driven to move by the adjusting rod 81, and finally the abutting surface 93 abuts against the reinforced inner container 01, and the pressing rod 73 pushes the reinforced inner container 01 to abut against the positioning plate 13.

[0051] The implementation principle of the welding positioning device for shell closing in the embodiment of the application is as follows: when the reinforced inner container 01 needs to be installed, the first fixed rod 31 is arranged in one of the fixing holes 22 of the hoisted reinforced inner container 01, the first fixed rod 31 supports the reinforced inner container 01, the reinforced inner container 01 is rotated, the remaining fixing holes 22 on the reinforced inner container 01 correspond to the second fixed rod 32, the reinforced inner container 01 is pushed, and the reinforced inner container 01 slides on the first fixed rod 31 and the second fixed rod 32. At this time, the worker pulls the adjusting rod 81, the adjusting rod 81 drives the moving block 72 to move towards the fixed block 71, under the action of the connecting rod 74, the pressing rod 73 rotates out of the mounting groove 16, the rotated pressing rod 73 abuts against the stop block 17, the moving block 72, the fixed block 71 and the pressing rod 73 move simultaneously when the adjusting rod 81 continues to move, and finally the pressing rod 73 pushes the reinforced inner container 01 to abut against the positioning plate 13. The limiting block 92 is separated from the sliding groove 9, the adjusting rod 81 is rotated, the limiting block 92 abuts against the end surface of the first fixed rod 31, at this time, the position of the adjusting rod 81 is fixed, and then the reinforced inner container 01 can be fixed.

[0052] Through the arrangement of the first fixed rod 31 and the second fixed rod 32, the reinforced inner container 01 can be supported without additionally arranging a supporting device, and the first fixed rod 31 can achieve the purpose of supporting the reinforced inner container 01.
