Abstract

The utility model discloses an assembly type power head of a numerical control drilling, boring and milling machine, and belongs to the technical field of assembly type power heads of numerical control drilling, boring and milling machines. The assembly type power head comprises a gantry and a power head with a main board, wherein the gantry is connected with a support board with guide rails, a motor base is connected on the upper end of the support board, a motor is mounted on the motor base, the support plate is further connected with a lead screw driven by the motor, a screw nut seat is matched and connected on the lead screw and is fixed on the main board, the upper portion of the main board is fixedly provided with a plurality of slide blocks which are arranged along the vertical direction, and the slide blocks are connected with the guide rails. The guide rails are shortened and a machine tool is lowered under the conditions of keeping stroke and processing precision of the power head unchangeable, and the equipment cost is reduced, because the guide rails are shortened, more space is residual convenient for clamping of work-pieces. The assembly type power head is especially suitable for the processing of impellers of large-sized generators.

Description

Total accepted way of doing sth unit head of boring and milling machine is bored in a kind of numerical control

Technical field

The utility model relates to total accepted way of doing sth unit head that boring and milling machine is bored in a kind of numerical control, especially relates to total accepted way of doing sth unit head that boring and milling machine is bored in a kind of numerical control that can be used for the machining large part.

Background technology

The mainboard 2 ' of present unit head 3 ' all be with hang on lathe gantry 1 ' on nc sliding table 4 ' be connected (as shown in Figure 1), wherein, the slide block 10 ' that has on the unit head mainboard 2 ' is positioned at the lower end of mainboard 2 ', cause unit head 3 ' body excessive like this, nc sliding table 4 ' is long, is not easy to the processing of large parts.

The utility model content

The purpose of this utility model is: provide a kind of and guaranteeing to make guide rail shorten under the constant prerequisite of unit head stroke, cost reduces, and has numerical control that the part of clamping workpiece is convenient in bigger space to bore total accepted way of doing sth unit head of boring and milling machine.

Degree can be according to the technical solution of the utility model: total accepted way of doing sth unit head of boring and milling machine is bored in a kind of numerical control, comprise gantry and the unit head that has mainboard, described gantry is connected with the gripper shoe that has guide rail, the gripper shoe upper end is connected with motor cabinet, motor is installed on the motor cabinet, gripper shoe also is connected with by described motor-driven screw mandrel, be connected with nut seat on the screw mandrel, nut seat is fixed on the mainboard, mainboard top is fixed with some slide blocks that vertical direction is arranged, and described slide block and described guide rail are connected.

Described gripper shoe is connected with screw mandrel with bearing housing by bearing block.

Described mainboard top is provided with 3 slide blocks.

The beneficial effects of the utility model are: guaranteeing that unit head stroke and constant situation lower guideway and the screw mandrel of machining accuracy shorten, reduced equipment cost, and because guide rail shortens, be convenient to the clamping of workpiece with regard to vacateing bigger space.

Below in conjunction with the drawings and specific embodiments the utility model is further specified.
