[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Depend on Figures 1 to 6It is known that a chassis panel drilling device includes a fixed base, the fixed base includes a horizontal rail 1 and a vertical rail 2, the vertical rail 2 is slidably mounted on the horizontal rail 1, and a drilling mechanism is slidably mounted on the vertical rail 2. The drilling mechanism includes a mounting plate 3 that slides on the vertical rail 2, a frame 4 that is telescopically mounted above the mounting plate 3, a drilling head 5 that extends from the bottom of the frame 4, a punch 6 that is telescopically mounted below the drilling head 5, a clearance hole 7 that is provided on the mounting plate 3, and a limiting ring 8 that is provided below the drilling head 5. When drilling, the limiting ring 8 contacts the panel, and the punch 6 performs the drilling operation on the panel from inside the limiting ring 8.

[0023] In practical use, this utility model

[0024] The mounting base is fixed on the panel, and the punching mechanism moves on the mounting base, causing the punch 6 to move to the punching position. During punching, the limiting ring 8 moves down and contacts the panel. The punch 6 punches the panel from inside the limiting ring 8. Due to the supporting effect of the limiting ring 8 on the panel, the punched edge is neat and the burrs are reduced.

[0025] To enable the limiting ring 8 to support the panel, the limiting ring 8 is made of magnetic material, which can be adsorbed and positioned with the panel.

[0026] To secure the mounting base to the panel, an electromagnetic block 12 is provided at the end of the transverse track 1. The electromagnetic block 12 becomes magnetic when energized, and can be fixed to the panel.

[0027] The transverse track 1 consists of two parallel tracks. A first lead screw 9 is rotatably mounted inside one track, and a first guide rod is mounted inside the other track. The longitudinal track 2 has the same structure as the transverse track 1. The longitudinal track 2 includes a second lead screw 10 and a second guide rod 11. One end of the longitudinal track 2 is threadedly connected to the first lead screw 9, and the other end of the longitudinal track 2 is slidably connected to the first guide rod. One end of the mounting plate 3 is threadedly connected to the second lead screw 10, and the other end of the mounting plate 3 is slidably connected to the second guide rod 11.

[0028] After the mounting base is fixed on the panel, the mounting plate 3 of the punching mechanism can move laterally and longitudinally to align the punch 6 with the punching position, thereby accurately aligning the punching position and completing the punching.

[0029] A first bevel gear 13 is coaxially mounted on the first lead screw 9. A second bevel gear 14, which meshes with the first bevel gear 13, is rotatably mounted on the transverse track 1. The second bevel gear 14 is coaxially connected to a first handwheel 15. Rotating the first handwheel 15 controls the movement of the longitudinal track 2 on the transverse track 1. A third bevel gear is coaxially mounted on the second lead screw 10. A fourth bevel gear, which meshes with the third bevel gear, is rotatably mounted on the longitudinal track 2. The fourth bevel gear is coaxially connected to a second handwheel 16. Rotating the second handwheel 16 controls the movement of the punching mechanism on the longitudinal track 2.

[0030] The horizontal and vertical movements of the punching mechanism are manually controlled by the first handwheel 15 and the second handwheel 16, and its displacement is accurately controlled by the ball screw so that it can be accurately aligned with the punching position.

[0031] Multiple first hydraulic cylinders 17 are provided between the frame 4 and the mounting plate 3. The first hydraulic cylinders 17 can control the distance between the frame 4 and the mounting plate 3 and adjust the distance between the punch head 5 and the panel, so that the limiting ring 8 contacts or moves away from the panel.

[0032] The punch head 5 is equipped with a second hydraulic cylinder 18. The punch 6 is fixed to the outer end of the second hydraulic cylinder 18. The second hydraulic cylinder 18 controls the extension and retraction of the punch 6. The second hydraulic cylinder 18 is used to control the punch 6 to complete the punching of the panel.

[0033] Two positioning lights 19 are fixed on the limiting ring 8. The axis of the positioning lights 19 forms a certain angle with the vertical direction, and the two positioning lights 19 are symmetrically arranged about the axis of the punch 6. When the first hydraulic cylinder 17 controls the lifting and lowering of the frame 4, the distance between the limiting ring 8 and the panel changes accordingly, and the illumination point of the two positioning lights 19 also changes. Adjusting the height of the limiting ring 8 makes the illumination points of the two positioning lights 19 coincide on the panel, that is, the illumination point is the location of the axis of the punch 6. Aligning this point with the marked drilling position can ensure the accuracy of the drilling position.

[0034] The frame 4 is equipped with a handle 20 and control buttons 21. The device can be moved or operated by holding the handle 20. Multiple control buttons 21 are provided to control the electromagnetic block 12, the first hydraulic cylinder 17 and the second hydraulic cylinder 18 respectively, thereby completing the drilling of the panel.

[0035] Compared with the prior art, this utility model has the following advantages: it can fix the drilling mechanism to the panel and directly drill holes in the position where there are no holes on the panel. The drilling mechanism has good stability and accurate drilling position, avoiding rework of the panel and improving assembly efficiency.
