Technical Field
[0001] The utility model belongs to the technical field of punching auxiliary positioning, in particular to a portable hydraulic punching machine positioner. Background Art
[0002] The hydraulic punching machine is a device used to punch holes in metal plates such as angle iron, flat iron, copper, and aluminum bars. It is particularly suitable for outdoor operations in industries such as electricity and construction. In the new, modified, and expanded substation projects, whether it is equipment terminals or busbars and grounding bars, bolt connections are indispensable, and on-site drilling is often required. The screw holes are usually made on-site using a hydraulic punching machine.
[0003] At present, in actual operation, when the hydraulic punching machine is punching, since the hydraulic punch needle is at a certain height from the sample to be punched, the placement of the sample to be punched is completely based on the operator's experience, and the operator's visual inspection is used to estimate whether the hydraulic punch needle can punch to the required punching position. This results in the punching accuracy being completely dependent on the operator's own ability, requiring multiple comparisons and test punches; insufficient accuracy will result in insufficient busbar contact area, which can easily cause node overheating.
[0004] Therefore, a new technical solution is urgently needed in the prior art to solve this problem. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a portable hydraulic punching machine positioner for solving the technical problems in the prior art that on-site punching relies on the operator's experience, requires multiple test punches, and has insufficient punching accuracy.
[0006] The technical solution adopted by the utility model is to provide a portable hydraulic punching machine positioner, including a bracket, the bracket is composed of a fixed part and a telescopic part, the first end of the fixed part is connected to the punching machine body by bolts, the telescopic part is a "V"-shaped structure, the first arm of the telescopic part and the second end of the fixed part are telescopically connected together and fixed by a locking piece, a laser pen is fixedly connected to the second arm of the telescopic part, the laser pen is used to point to the position to be punched on the sample, the fixed part is provided with a scale, the scale value gradually increases from the first end to the second end, the first arm is provided with an indicator mark, when the first arm is telescoped relative to the fixed part, the scale value indicated by the indicator mark and the scale on the fixed part coincides represents the total effective length of the fixed part and the first arm at that moment.
[0007] Through the above-mentioned design scheme, the utility model can bring the following beneficial effects: the portable hydraulic punching machine positioner disclosed by the utility model, by arranging a fixed part and a telescopic part on the bracket, and arranging scales and indicator marks thereon, can adjust the total effective length of the positioner bracket in the horizontal direction according to the thickness of different samples to be punched, so that the laser spot is accurately aligned with the position mark to be punched on the sample, thereby realizing precise positioning. The punching accuracy of the portable hydraulic punching machine positioner of the utility model is extremely high, and there is no need for trial punching and multiple comparisons; the positioner is connected to the hydraulic punching machine by bolts, which is easy to carry and install, and is more conducive to on-site disassembly and assembly, with a simple structure and flexible operation.

[0011] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:
[0012] like Figure 1As shown, the utility model is a portable hydraulic punching machine positioner, and the hydraulic punching machine includes a punching machine body 1 and a base 2. A hydraulic punching needle 3 is provided at the lower end of the punching machine body 1, and a loading platform 4 corresponding to the hydraulic punching needle 3 is fixedly connected to the upper surface of the base 2, and the hydraulic punching needle 3 reciprocates between the punching machine body 1 and the loading platform 4 in the vertical direction. The portable hydraulic punching machine positioner includes a bracket, which is arranged at the upper end of the punching machine body 1, and the bracket includes a fixed part 5 and a telescopic part 6, and the first end of the fixed part 5 is fixedly connected to the punching machine body 1 through a bolt 7. The telescopic part 6 has a "V"-shaped structure. The second end of the fixed part 5 and the first arm 61 of the telescopic part 6 are telescopically connected together through a locking member 8. A laser pen 9 is fixedly connected to the second arm 62 of the telescopic part 6, and the light spot of the laser pen 9 points to the position where the punching is required on the sample 10 to be punched. The "V"-shaped angle between the first arm 61 and the second arm 62 is α. The size of the angle α is sufficient to allow the light spot of the laser pen 9 to be irradiated onto the loading platform 4. The fixing part 5 is provided with a scale, and the scale value increases gradually from the first end to the second end. The first arm 61 is provided with an indicator mark, which can be a triangle or an arrow pointing in the direction of the scale mark. When the first arm 61 is extended or retracted relative to the fixing part 5, the scale value is indicated at the place where the indicator mark and the scale mark on the fixing part 5 overlap. At this time, the scale value indicated by the indicator mark represents the total effective length of the fixing part 5 and the first arm 61 at that moment, that is, Figure 2 The length from point A to point C.
[0013] like Figure 2 As shown, the working principle of the utility model is: the V-shaped angle of the telescopic part 6 is known to be α, and the thickness of the fixed part 5 is h 1 The height from the upper surface of the punching machine body 1 to the upper surface of the stage 4 is h 2 The thickness of the sample 10 to be punched is h 3 , l 1 is the total effective length of the locator bracket in the horizontal direction, that is, the total effective length of the fixing part 5 and the first arm 61 at a certain moment. Figure 2 The length from point A to point C, point A is the intersection of the upper surface of the fixing part 5 and the axis of the hydraulic punch 3, and point C is the intersection of the reverse extension line of the laser pen 9 laser emission direction and the first arm 61. In the right triangle ABC, it can be known from the tangent function formula that: According to the thickness h of the sample 10 3 It can be calculated that l 1 Open the locking member 8, extend or shorten the first arm 61, and adjust the scale to l 1 The value of the punching hole is set, the locking piece 8 is locked, the laser pen 9 is turned on, the position mark of the sample 10 to be punched is aligned with the laser spot, and the hydraulic punching machine is turned on for punching. The utility model can realize the accurate positioning of the punching position of samples of different thicknesses by laser, and the punching accuracy is extremely high.
