Embodiment

[0030] Example: such as figure 2 with image 3 As shown, a head of a sheet metal drilling machine includes a spindle rotation mechanism, a Z-axis feed mechanism, a cooling water supply structure, and an eccentric drilling mechanism.

[0031] The eccentric drilling mechanism is mainly composed of a drill bit 15, a main shaft 14, an eccentric action block 16, a moving block 17 and a drilling cylinder 18. The shank end of the drill bit 15 is provided with a tapered counterbore 42, and the counterbore 42 is larger than the diameter of the lower end of the main shaft. The main shaft 14 The lower end stretches in the counterbore 42, and hinges with the drill bit 15 through the pin 37 in the middle section (see image 3 ), so that the drill bit 15 can swing and deflect relative to the main shaft 14, that is, the drill bit 15 can still swing with the hinge as the base point. The drill bit 15 afterbody is provided with a pair of first slopes 38 (see image 3), the eccentric action ...

Abstract

The plate drilling machine head includes one main shaft rotating mechanism, one Z-axis feeding mechanism, one cooling water providing mechanism, and one eccentric reaming mechanism. The eccentric reaming mechanism comprises one bit with one pair of first bevels in the tail for controlling its swing, one main shaft with lower end hinged to the middle section of the bit for swinging the bit, one eccentric block with one pair of second bevels to slide fit the first bevels, one shifting block capable of shifting in Z direction, and one reaming stroke acting unit acting on the shifting block in Z direction. The present invention has high quality of drilled hole.

Description

technical field [0001] The invention relates to a plate drilling machine for back-cut anchoring wall decoration panels, in particular to a machine head used for drilling on the plate drilling machine. Background technique [0002] With the development of the building decoration industry, the appearance of urban buildings is not only the pursuit of shape, more buildings begin to pay attention to the beauty, practicality and environmental protection of the exterior wall decoration, so curtain wall panels are adopted by more and more construction companies . At present, the curtain walls of urban buildings mostly use decorative plates such as slate, ceramic plates or microcrystalline slabs, and the fixing methods are mostly back-cut anchoring installations. Back-cut anchor installation needs to drill blind holes on the back of the decorative panel, so that the panel can be suspended and installed on the exterior wall of the building with back-cut anchor bolts and L-shaped anch...
