Embodiment Construction
[0020] The accompanying drawings restrictively disclose the specific structures of the embodiments of the present invention, and the present invention will be further described below in conjunction with the accompanying drawings.
[0021] Depend on figure 1 It can be seen that a workbench device for movable feeding of a floor boring machine includes a floor boring machine 1, a boring machine spindle 2, a base 3 positioned and installed on a fixed workbench of the floor boring machine 1, and a movable workbench 5 is arranged on it . In this embodiment, the workpiece 4 is a box, and the box contains two workstations to be processed. During specific implementation, the workpiece 4 is positioned and fixed on the movable table 5, and is automatically fed along with the movable table 5, while the axial position of the main shaft of the boring machine remains unchanged.
[0022] Depend on figure 2 It can be seen that the base 3 is divided into two parts, the left and the right, a...

The invention relates to a working table device used for a floor type boring machine and capable of being fed movably. The working table device is composed of a movable working table, a base and a speed adjusting device, wherein a lead screw nut mechanism is arranged in the movable working table, a lead screw nut is installed on a ball screw which is supported in a lead screw support seat, and the lead screw support base is installed on the base; the base is divided into a left part and a right part, the base and a fixed working table of the floor type boring machine are positioned and fixed through bolts and fastening nuts in a T-shaped groove, and the base is provided with a dovetail structure; a transmission gear is arranged in the speed adjusting device, a dovetail structure is arranged at the bottom, and the speed adjusting device is installed on a support base and provided with a bolt locking device. According to the way of achieving the purpose, the working table device capable of being fed movably is arranged on the fixed working table of the floor type boring machine, the speed adjusting device is driven by a servo motor, and then the movable working table is pulled through the ball screw, so that axial feeding is not needed in the machining process of a main shaft of the boring machine, the working table can be fed automatically, the machining accuracy of workpieces is improved, and in this way the purpose of the working table device is achieved.
Description
technical field [0001] The invention relates to a boring device for machining inner holes, especially for a plurality of holes to be machined in a workpiece, and there is a relatively high coaxiality requirement among them, and a mobile floor boring machine provided Feed table device. Background technique [0002] In the gearbox manufacturing industry, the box is used as the base part of the gearbox, and each shaft of the box has at least two support points, and the position accuracy of each support point itself determines the operating status of the gearbox. The bearing hole of the box body is the positioning mechanism of the transmission shaft system in the reduction box, and its dimensional accuracy and shape and position tolerance grade play a decisive role in the transmission accuracy of each shaft system, so boring has become the most critical process in the box body processing one. [0003] At present, with the increase of the size of the gearbox, the boring process...
