Description

Technical Field

[0001] The utility model relates to the technical field of busbar processing, in particular to a carving and calibration workpiece. Background Art

[0002] When processing busbars or zero bars, multiple mounting holes need to be punched out at predetermined locations. To facilitate later installation operations, it is often necessary to first measure and then mark multiple punching points on the busbar or zero bar, and then the operator manually feeds the material to perform the punching operation. Currently, when marking the punching points, they are measured using a tape measure, which results in large errors. This measurement method leads to large calibration errors of the punching points, thus affecting the installation of the conductors. Utility Model Content

[0003] The utility model provides a carving and calibration workpiece to solve the deficiencies of the above-mentioned prior art and the problem of large calibration errors of busbar or zero row punching points, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

The zero row or bus bar can be limited by the provided limiting groove. The center line of the zero row or bus bar in the width direction and the center line of the long strip in the width direction are located on the same vertical plane by limiting, thereby ensuring the accuracy of the calibration point. Of course, the limitation facilitates the calibration operation in the later stage.

The calibration operation of the calibration point is facilitated by the movable carving rod. When it is fixed on the lower movable plate, it is convenient to move along the center line of the zero row or busbar width direction through the carving rod, and then to carve the center line. When it can move on the lower movable plate, the carving operation of each calibration point can be facilitated by the carving rod and the scale on the long plate.

[0006] Furthermore, in order to improve the positioning effect of the zero row or the busbar, the limiting groove is set to an isosceles trapezoidal structure, and the inner end of the limiting groove is the large end.

[0007] Furthermore, narrow slits are respectively provided at both ends of the upper plate, and the width of the narrow slits is consistent with the width of each scale line, which facilitates precise positioning operations during engraving.

[0008] Furthermore, in order to facilitate the carving operation of the carving rod, the carving rod has a pointed cone structure.

[0009] Furthermore, in order to facilitate the clamping operation of the zero row or the busbar, a clamping screw is rotatably provided on the long strip, a rotating head is provided at the upper end of the clamping screw, the clamping screw is connected to the movable plate by a screw, and a movable cross plate is provided at the inner end of the movable plate.

[0016] Figure 4 Shows a three-dimensional structure of one embodiment Figure 2 . DETAILED DESCRIPTION

[0017] like Figures 1 to 4 As shown, a workpiece for engraving and calibration includes a long plate 1, the upper wall of the long plate 1 is provided with a scale, a pair of long holes 10 are opened on the long plate 1, and movable sleeves 30 are respectively provided at both ends of the long plate 1. The lower wall of the inner end of the movable sleeve 30 is provided with a vertical plate 31, and a pair of vertical holes 32 are opened on the vertical plate 31. Screws 33 are passed through the vertical holes 32, and a clamping plate 34 is provided at the inner end of the screw 33. A limiting groove is opened on the inner wall of the clamping plate 34, and the limiting groove is an isosceles trapezoidal structure, and the inner end of the limiting groove is the large end.

[0018] A clamping screw 2 is rotatably provided on the long strip 1, and a rotating head 20 is provided at the upper end of the clamping screw 2. The clamping screw 2 is connected to a movable plate 21 by a screw. A movable cross plate 22 is provided at the inner end of the movable plate 21, and an action rod is rotatably provided at both ends of the movable cross plate 22. A movable guide sleeve 23 is provided on the long strip 1, and a pair of clamping movable plates 24 are movably provided in the movable guide sleeve 23. An inclined hole 25 is provided on the clamping movable plate 24, and the action rod passes through the inclined hole 25. A pull plate 26 is provided at the outer end of the clamping movable plate 24, and a concave plate 27 is installed on one side of the movable sleeve 30. The upper end of the concave plate 27 is connected to a pressing screw 29 by a thread, and the lower end of the pressing screw 29 acts on the pulling plate 26.

[0019] A movable screw 4 is passed through the long hole 10, and an upper plate 40 is provided at the upper end of the movable screw 4. Narrow slits are respectively provided at both ends of the upper plate 40. A lower movable plate 41 is provided at the lower end of the movable screw 4. A T-shaped slot is provided on the lower movable plate 41. A pull-out plate 42 is movably provided in the T-shaped slot, and a carving rod 43 is provided on the pull-out plate 42. The carving rod 43 has a pointed cone structure, and a connecting screw is provided at one end of the pull-out plate 42.

[0020] When operating this embodiment, the operator first adjusts the position of the two clamping plates 34 on the pull plate 26 according to the length of the zero row or the busbar. During the adjustment, the moving distance of the clamping plates 34 needs to be equal. After the adjustment is completed, the position of the clamping plates 34 is fixed by pressing down the screws 29.

[0021] The operator then places the neutral bar or busbar between the clamping plates 34 .

[0022] Then the operator rotates the clamping screw 2, which will drive the movable cross plate 22 to move during the rotation. The movement of the movable cross plate 22 will drive the action rod to move. During the movement, the action rod will act on the inclined hole 25, thereby making the clamping movable plates 24 approach each other. When the clamping movable plates 24 approach each other, the clamping plates 34 will be used to limit the two ends of the zero row or the bus bar.

[0023] Then move the zero row or busbar upward and lock it with the screw 33 so that the lower end of the carving rod 43 is pressed against the zero row or busbar, and fix the carving rod 43 to the lower movable plate 41 with the connecting screw. Then move the carving rod 43 and perform the carving operation with the tip of the carving rod 43. Of course, the carving rod 43 can also be set as a carving pen. When the center line of the zero row or busbar in the width direction is carved, cancel the lock of the connecting screw and then move it along the length direction of the long hole 10. During the movement, the punching point is carved with the help of the scale lines on it. After the carving is completed, the zero row or busbar is removed.

[0024] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Therefore, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
