Description

Technical Field

[0001] This utility model relates to the field of busbar processing technology, and in particular to a busbar end flattening device. Background Technology

[0002] Busbars are installed on electrical control cabinets as power transmission lines. To facilitate connection and fixation, mounting holes are often machined at both ends by punching. However, when machining mounting holes by punching, the force-bearing surface of the punch is easily concave downwards. During installation, if the inner end of the mounting nut contacts the concave or convex surface, the reduced contact area will cause overheating at the connection point when power is applied. The current method is to tap the two surfaces with a flat-headed hammer to reduce the concave and convex deformation. However, this method can easily lead to deformation of other parts. Utility Model Content

[0003] This utility model provides a busbar end flattening device to overcome the shortcomings of the prior art and solve the problem of deformation during the stamping process of the busbar mounting hole, which has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A busbar end flattening device includes a base plate, with support blocks mounted on both ends of the base plate by screws. A side plate is machined on the upper end of each support block, and an upper strip is provided on the upper end of each side plate. A fixing block is fixed to the upper end of each support block by screws. A support plate is machined between the fixing blocks. A pair of vertically arranged oblong holes are provided on the side plates, and movable screws are movably installed within the oblong holes. A movable inner plate is threaded to the inner end of the movable screws on the same side. A pressure plate is welded to the lower end of the movable inner plate. An inner crossbar is welded to the inner side of the movable inner plate. Two pairs of connecting plates are symmetrically arranged on the inner crossbar with its midpoint along its length as the symmetry point. Each pair of connecting plates is rotatably mounted on the inner crossbar via a lower shaft. A convex plate is rotatably mounted on the other end of each pair of connecting plates via an upper shaft. A movable block is welded to the upper end of the convex plate. A lead screw is rotatably mounted on the upper end of the side plate, with the threads at both ends of the lead screw rotating in opposite directions. The movable block is threaded to the lead screw. A rotating head is fixed to one end of the lead screw by a pin.

[0005] Furthermore, the outer end of the movable screw on the same side is connected to a limiting outer plate via a threaded connection.

[0006] Furthermore, a lower pressing platform is machined on the lower wall of the pressure plate.

[0007] Furthermore, a rotating seat is fixed to the lower wall of the upper strip by screws, and a lead screw is rotatably mounted on the rotating seat. A pair of nuts are connected to the lead screw, and the nuts are located on both sides of the rotating seat.

[0008] Furthermore, a central support base is fixed to the base plate with screws, and the upper end of the central support base is fixed to the support plate.

[0009] Furthermore, a pair of strip-shaped holes are opened at both ends of the support plate parallel to its length direction. Movable rods are movably installed in the strip-shaped holes. The upper end of each pair of movable rods is connected to a limit block by a thread, and the lower end of each pair of movable rods is connected to a lower block by a thread. An upper top plate is movably installed on the movable rod. The upper top plate is located between the lower block and the support plate. An upper rotating plate is rotatably installed on the outside of the lower block by a rotating screw. One end of the upper rotating plate abuts against the lower wall of the upper top plate. A lower extension block is welded on the upper top plate to limit the rotation of the upper rotating plate.

[0010] The advantages of the above technical solution are: This invention utilizes the interaction between the provided support plate and the lower pressure table. When the lower pressure table presses down, both can flatten the end of the busbar. During operation, unnecessary deformation of the busbar can be minimized. Furthermore, the flattening operation can be achieved simply by rotating the lead screw, thereby improving operability and convenience.

[0011] This invention also constrains the width direction of the busbar by limiting side blocks during flattening, thereby ensuring the flattening effect.

[0012] This invention also uses components such as a central support base to improve the support effect on the support plate. Attached Figure Description

[0015] Figure 2 A three-dimensional structure of one embodiment is shown. Figure 2 . Detailed Implementation

[0016] like Figures 1-2As shown, a busbar end flattening device includes a base plate 2. Support blocks 24 are screwed to both ends of the base plate 2. A side plate 25 is machined onto the upper end of the support block 24. An upper strip 42 is provided on the upper end of the side plate 25. A fixing block 22 is fixed to the upper end of the support block 24 by screws. A supporting plate 21 is machined between the fixing blocks 22. A middle support seat 20 is fixed to the base plate 2 by screws. The upper end of the middle support seat 20 is fixed to the supporting plate 21. A pair of vertically arranged oblong holes 26 are provided on the side plate 25. Movable screws 27 are movably installed within the oblong holes 26. A movable inner plate 29 is threaded to the inner end of the movable screw 27 on the same side. A limit outer plate 28 is threaded to the outer end of the movable screw 27 on the same side. A pressure plate 30 is welded to the lower end of the movable inner plate 29. A lower pressure table 32 is machined on the lower wall. An inner horizontal bar 31 is welded to the inner side of the movable inner plate 29. Two pairs of connecting plates 34 are symmetrically arranged on the inner horizontal bar 31 with the midpoint of its length direction as the symmetry point. Each pair of connecting plates 34 is rotatably mounted on the inner horizontal bar 31 via a lower shaft 33. The other end of each pair of connecting plates 34 is rotatably mounted on a convex plate 36 via an upper shaft 35. A moving block 37 is welded to the upper end of the convex plate 36. A lead screw 38 is rotatably mounted on the upper end of the side plate 25. The threads at both ends of the lead screw 38 are in opposite directions. The moving block 37 is threadedly connected to the lead screw 38. A rotating head 39 is fixed to one end of the lead screw 38 by a pin. A rotating seat 40 is fixed to the lower wall of the upper plate 42 by screws. The lead screw 38 is rotatably mounted on the rotating seat 40, and a pair of nuts 41 are connected to the lead screw 38. The nuts 41 are located on both sides of the rotating seat 40.

[0017] A pair of strip holes 23 are provided at both ends of the support plate 21, parallel to its length direction. Movable rods 43 are movably installed in the strip holes 23. The upper end of each pair of movable rods 43 is connected to a limiting side block 44 by a thread, and the lower end of each pair of movable rods 43 is connected to a lower block 45 by a thread. An upper top plate is movably installed on the movable rods 43. The upper top plate is located between the lower block 45 and the support plate 21. An upper rotating plate 47 is rotatably installed on the outside of the lower block 45 by a rotating screw 46. One end of the upper rotating plate 47 abuts against the lower wall of the upper top plate. A lower extension block 48 is welded to the upper top plate to limit the rotation of the upper rotating plate 47.

[0018] In this embodiment, the operator first adjusts the spacing between the limiting side blocks 44 according to the width of the busbar 1. After adjustment, the upper top rotating plate 47 is rotated. During rotation, its upper end will abut against the lower wall of the upper top plate, so that the upper wall of the upper top plate abuts against the lower wall of the support plate 21. At this time, the lower extension block 48 limits and constrains one side of the lower extension block 48.

[0019] The operator then places the end of busbar 1, especially the position where the mounting hole of busbar 1 is located, directly below the lower pressure platform 32. The operator then inserts a pry bar or similar tool into the insertion hole on the rotating head 39 and rotates the lead screw 38 using the pry bar or similar tool. When the lead screw 38 rotates, it will cause the moving blocks 37 to move closer together. As the moving blocks 37 move closer together, the included angle between the connecting plates 34 will decrease. At this time, the lower pressure platform 32 will move downward along the length direction of the waist-shaped hole 26. During the downward movement, the lower wall of the lower pressure platform 32 will act on the upper wall of busbar 1, and the upper side of the support plate 21 will abut against the lower wall of busbar 1, and finally flatten the position where the mounting hole 10 of busbar 1 is located. After flattening, the lead screw 38 is rotated in the opposite direction, and then the other end of busbar 1 is flattened.
