Embodiment 1

[0020] This embodiment provides a dual-coordinate feed power box, such as figure 1 As shown, it includes a power box 1 installed on the frame, which is characterized in that: the inside of the power box 1 is equipped with an outer eccentric sleeve 2 through a bearing, and an inner eccentric sleeve 3 is installed in the outer eccentric sleeve 2 through a bearing. The main shaft 4 is installed in the inner eccentric sleeve 3 through bearings, one end of the main shaft 4 is connected to the large pulley 5, and the large pulley 5 is connected to the power source 7 through the belt 6 (the power source here can be a motor, or a hydraulic cylinder, etc. powered equipment) to obtain power.

[0021] The outer walls of the outer eccentric sleeve 2 and the inner eccentric sleeve 3 are respectively connected with a power rotation drive mechanism, and the power rotation drive mechanism drives the outer eccentric sleeve 2 and the inner eccentric sleeve 3 to rotate; the belt 6 is equipped wi...

Embodiment 2

[0031] On the basis of embodiment 1, this embodiment is further described, referring to figure 1 , the power rotation drive mechanism here includes a drive worm gear 9 that engages with the outer wall of the outer eccentric sleeve 2 or inner eccentric sleeve 3 to transmit power and a drive worm 10 that is installed in cooperation with the drive worm gear 9 , and the drive worm 10 is perpendicular to the outer eccentric sleeve 2 Or the axial direction of the inner eccentric sleeve 3 is arranged.

[0032] Taking the power rotation drive mechanism connected to the outer eccentric sleeve 2 as an example, the drive worm 10 is driven to rotate by a servo motor. Due to the interaction between the drive worm 10 and the drive worm 9, the drive worm 10 rotates and the drive worm 9 is perpendicular to the transmission The worm 10 rotates in one direction, and then the transmission worm 10 drives the outer eccentric sleeve 2 to rotate to realize the rotation of the outer eccentric sleeve ...

Embodiment 3

[0035] In the above two embodiments, since the position of the main shaft 4 changes relative to the position of the power box 1, the center distance of the belt pair of the belt 6 changes accordingly. Here, the belt 6 is a V-belt or a toothed synchronous belt, so the belt drive Auxiliary will be provided with flexible tensioning mechanism 8, the reliable tensioning of keeping belt. In this embodiment, the flexible tensioning mechanism 8 includes a tensioning wheel that interferes with and acts on the belt 6 , the tensioning wheel is connected with a spring telescopic element, and the other end of the spring telescopic element is fixed on the frame.

[0036] In this structure, the spring expansion part is a structural part with a specific force. According to the tension requirements of the belt, an appropriate spring is selected to realize the structural function. The tensioner is close to the belt, making the belt tighter; if the belt becomes tighter as the position of the mai...

Abstract

The invention discloses a double-coordinate feeding power box. The double-coordinate feeding power box comprises a power box body installed on a rack. An outer eccentric sleeve is installed in the power box body, an inner eccentric sleeve is installed in the outer eccentric sleeve, and a main shaft is installed in the inner eccentric sleeve. The outer wall of the outer eccentric sleeve and the outer wall of the inner eccentric sleeve are each connected with a power rotation driving mechanism. The power rotation driving mechanisms drive the outer eccentric sleeve and the inner eccentric sleeve to rotate. A flexible tensioning mechanism is installed on a belt and makes contact with the belt to be used for tensioning the belt. The double-coordinate feeding power box is compact in structure and small in size; by means of the double-eccentric principle, a linear movement pair, moving on two coordinates, of the main shaft or a workbench is changed to rotate along the two eccentric rotating drums by driving the rotating drums to rotate, adjusting or feeding of any position in a certain area is achieved, and because all the adjustment is achieved in the power box, equipment rigidity is improved while the mechanical structure size is greatly reduced and energy consumption is low.

Description

technical field [0001] The invention is used for spindle feed or worktable movement of a cutting machine tool (such as a special boring and milling machine) to realize small-stroke high-precision relative position adjustment, and is specifically a dual-coordinate feed power box. Background technique [0002] The design of traditional boring and milling machines mostly adopts the structure of screw guide rail pair and rack and pinion rail pair structure, and the relative feed motion of the spindle and the workpiece is realized by moving the power box components or the worktable. Using this type of structure, because the power box assembly or workbench needs to be driven, and the power box and workpiece workbench on a large machine tool are huge, which makes the drive power and mechanical structure size larger; because the controlled part has a large motion inertia, it can realize fast and high Accuracy control is difficult, and the applicability of equipment online layout is ...
