Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

The utility model provides a center perforating device of large-scale cylinder class product, including lathe 1, be provided with cutter mount pad 11, chuck 12 on the lathe 1, still including the centre frame 2 that is used for supporting the cylinder product. Steady rest 2 is often applied to and provides the gyration to the cylinder product and supports, but large-scale cylinder blank can't use steady rest 2 to provide the gyration and support, so steady rest 2 is in the utility model discloses in be special setting for provide normal static support for cylinder class product.

The tool mount 11 is fixed with a drill 3 through a fixing member 4, and the drill 3 is an existing product purchased in the market. The drill bit of the drill 3 corresponds to the center of the chuck 12. After chuck 12 and centre frame 2 are fixed cylinder class product, directly bore the centre bore with drilling machine 3, the utility model discloses a focus just lies in the combination of drilling machine 3 and lathe 1, obviously is different from the mode that utilizes chuck 12 to drive cylinder class product rotation and install the drill bit on the tailstock among the prior art.

The drilling machine 3 comprises a shaft body part coaxial with the drill bit and a transmission part for mounting a motor and transmitting power to the drill bit; the shaft body part and the transmission part are arranged in an L shape.

The fixing member 4 includes a first supporting member 41 for supporting the shaft portion, the first supporting member 41 is "L" shaped, and two first supporting members 41 are provided. The first support 41 is fixed to the shaft body portion by a horizontally disposed bolt; the fixing assembly 4 further includes a second supporting member 42 in a "U" shape, and the second supporting member 42 is pressed and fixed by a top thread of the tool mounting base 11. The first supporting member 41 is slidably connected to the second supporting member 42, the second supporting member 42 is horizontally provided with a sliding slot 422, and the first supporting member 41 is provided with a sliding block 411 matched with the sliding slot 422.

The second supporting member 42 is provided with a bending portion 421, the bending portion 421 is fixedly connected to the transmission portion through a bolt, and when the bending portion 421 is connected to the transmission portion, the opposite surfaces of the first supporting member 41 and the second supporting member 42 are attached to each other.

The utility model discloses an implementation process does: the first supporting piece 41 and the drilling machine 3 are preassembled, the second supporting piece 42 is calibrated in advance and is pressed and fixed by the jackscrew of the cutter mounting seat 11, when the drilling machine is installed, only the first supporting piece 41 slides along the sliding groove 422, and the bent part 421 and the drilling machine 3 are fixed relatively through one bolt, the steps are very simple, the bolt provides supporting force by means of the surfaces, which are attached to each other, of the two first supporting pieces 41 and the second supporting piece 42, and the limitation of six degrees of freedom of the drilling machine 3 is also met.
