Description

Technical Field

[0001] The utility model relates to the field of mechanical processing of truck parts, in particular to centering punching machine equipment, and specifically to an adjusting device for an axle centering punching machine. Background Art

[0002] To facilitate the machining of mounting holes on finished truck axles, a conventional outdoor centering punching machine is disclosed. The machine includes a centering ring with multiple mounting holes. Multiple sliders are connected to one end face of the ring, symmetrically arranged about the centerline of the ring. The sliders are connected to a slide rail, which in turn is connected to a drilling mechanism. The drilling mechanism includes a vertically movable feed power motor with guide mechanisms on either side. This centering punching machine can efficiently and accurately machine mounting holes on existing truck axles, and can be used for axles of various sizes, large, medium, and small.

[0003] The centering ring is fixedly connected to the truck wheel hub by screws, so that the entire punching machine is fixed to the truck wheel hub. However, since the centering ring is screwed to the truck wheel hub through multiple mounting holes on it, when the mounting holes of the centering ring are too large, the axis of the centering ring and the wheel hub may deviate. Therefore, during processing, the position of the machined mounting hole may be off-center. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] In the description of the utility model, it should be understood that the terms "front," "rear," "upper," "lower," "left," "right," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limiting the utility model. The utility model is further described below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-5 As shown, this embodiment discloses an adjustment device for an axle bridge centering punch, which mainly includes a centering ring 1, a first base plate 2, an X-direction connecting plate 3, a second base plate 4, and a Y-direction connecting plate 5. To facilitate replacement of the centering ring 1, the upper surface of the positioning ring is detachably connected to the first base plate 2 via a bolt assembly. The first base plate 2 is machined with an opening identical to the axial hole of the centering ring 1.

[0030] The middle of the first base plate 2 is a circular area, and the left and right sides are square areas. A first guide rail groove 6 is processed on the left side of the first base plate 2, and a first adjustment cavity 7 is processed on the right side. The first guide rail groove 6 and the first adjustment cavity 7 both extend in the left and right directions. A first slider 10 is processed at the bottom of the X-axis connecting plate 3. The first slider 10 can slide with the first guide rail groove 6. A first adjustment screw 8 is rotatably installed in the first adjustment cavity 7. The first adjustment screw 8 is threadedly connected to the first connecting block 9. The first connecting block 9 slides in the first adjustment cavity 7. The top surface of the first connecting block 9 is detachably connected to the bottom of the X-axis connecting plate 3 by a bolt assembly. The X-axis connecting plate 3 is similar in shape to the first base plate 2. An opening connected to the axial hole of the centering ring 1 is provided on the X-axis connecting plate 3. By rotating the first adjustment screw 8, the X-axis connecting plate 3 can be fine-tuned and moved in the left and right directions.

[0031] Support frames 11 are installed on the left and right sides of the X-axis connecting plate 3. The upper ends of the two support frames 11 are fixed to the second base plate 4 by a bolt assembly. The overall profile of the second base plate 4 is similar to that of the X-axis connecting plate 3. Second guide rail grooves 12 extending front and back are symmetrically provided on the left and right sides of the second base plate 4. A second adjustment cavity 13 is machined on the front side of the second base plate 4. A second adjustment screw 14 is rotatably installed in the second adjustment cavity 13. A second connecting block 15 is threadedly connected to the second adjusting screw 14. The second connecting block 15 slides in the second adjustment cavity 13. The top surface of the second connecting block 15 is detachably connected to the bottom of the Y-axis connecting plate 5 by a bolt assembly. Second sliders 16 are respectively installed on the left and right sides of the bottom of the Y-axis connecting plate 5. The second slider 16 slides in conjunction with the second guide rail groove 12. By rotating the second adjustment screw 14, the Y-axis connecting plate 5 can be fine-tuned and moved in the front-back direction. Mounted on the Y-connecting plate 5 is a drilling mechanism 17 that can be raised and lowered. This mechanism is a conventional technique for drilling holes in mechanical components, as fully disclosed in Utility Model Publication No. CN 210937283 U, and will not be described in detail here. The Y-connecting plate 5 also has a hole through which the drill bit of the drilling mechanism 17 can pass. When the drilling mechanism 17 descends, the drill bit sequentially passes through the Y-connecting plate 5, the second base plate 4, the X-connecting plate 3, and the first base plate 2 to reach the processing surface.

[0032] In order to facilitate the adjustment of the first adjusting screw 8 and the second adjusting screw 14, hexagonal holes are provided at the outer ends of the first adjusting screw 8 and the second adjusting screw 14, and the construction workers can directly use a hexagonal wrench to realize rotation adjustment.

[0033] It is worth noting that during use, when the centering ring 1 is fixedly connected to the axle bridge hub, the drill bit position may deviate due to the size of the mounting hole of the centering ring 1. This deviation generally ranges from 2 cm. By using the axle bridge centering punch adjustment device disclosed in this embodiment, fine-tuning the left and right direction of the X-axis connecting plate 3 and the front and rear direction of the Y-axis connecting plate 5 can align the drill bit with the axis position of the processing surface, thereby adjusting the relative position of the drill bit and controlling the drill bit of the drilling mechanism 17 to penetrate the opening for drilling, thereby improving the accuracy of drilling.
