Problems solved by technology

Since it is difficult for a machine tool with the above functions to satisfy the accuracy, dynamic performance, reliability and low cost at the same time, it is often necessary to transfer the workpiece back and forth between the horizontal car and the swing axis machine tool for tool calibration in actual processing.
In this way, not only the manufacturing cost is high, but also the utilization rate of the machine tool is not high. The cumbersome operation greatly increases the processing auxiliary time and the errors generated therein, affects the processing efficiency and processing accuracy, and increases the cost.
Most of the machine tools that can complete this type of processing on the market are expensive

Embodiment 1

[0048] Such as figure 1 , figure 2 , image 3 and Figure 4 Shown is the first embodiment of the vertical-horizontal conversion virtual axis swing angle milling head disclosed in the present invention, including a milling head box 10 , a swinging spindle box 20 , an electric spindle 30 , a servo motor 40 and a ball screw 50 . Such as Figure 11 and Figure 12 As shown, the milling head box 10 includes a pair of opposite support plates 106 and a connecting plate 107 , the two support plates 106 are connected through the connecting plate 107 , and an accommodation cavity 101 is formed between the two support plates 106 and the connecting plate 107 . Such as figure 2 and Figure 7 As shown, the swinging headstock 20 is placed in the lower part of the housing cavity 101 and the two sides of its front end are hinged with the front end of the milling head box 10 through the first hinge 102. The electric spindle 30 is installed in the 20, and the second hinge 104 is installe...

Embodiment 2

[0053] Such as Figure 16 , Figure 17 and Figure 18 Shown is the second embodiment of the vertical-horizontal conversion virtual axis swing angle milling head disclosed in the present invention. The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the ball screw nut support ear 201 is horizontally symmetrical placed on both sides of the axis of the electric spindle 30, so the ball screw nut is in the middle of the rear end of the swing headstock, that is, the axis of the electric spindle and the axis of the ball screw are in the same plane. However, in this embodiment, the ball screw nut support ear 201 is placed on one side of the axis of the electric spindle, so the ball screw nut is on one side of the rear end of the swing headstock, so that the axis of the electric spindle and the axis of the ball screw are not in common noodle.

[0054] Specifically, such as Figure 16 , Figure 17 and Figure 18 As shown, there is a ball screw nut fixi...

Embodiment 3

[0056] Such as Figure 19 and Figure 20 Shown is the third embodiment of the vertical-horizontal conversion virtual axis swing angle milling head disclosed in the present invention. The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the first bearing is installed on both sides of the swing headstock. On the side and the axis of the first pin shaft is coplanar with the axis of the electric main shaft. In this embodiment, the first bearing is installed on both sides of the swing headstock but when the swing headstock is in a horizontal position, the horizontal plane where the axis of the first pin shaft is located is below the horizontal plane where the axis of the electric spindle is located, in order to Increase the distance between the axis of the first pin shaft and the axis of the electric spindle to facilitate the installation of the first bearings on both sides of the front end of the swing headstock. There is a first bearing mounting platf...

Abstract

The invention discloses a vertical and horizontal conversion virtual axial-swing-angle milling head. The milling head comprises a milling head box, a swing spindle box, an electric spindle, a servo motor and a ball lead screw; the milling had box is provided with a containing cavity, the swing spindle box is arranged at the lower portion of the containing cavity and hinged to the milling head boxthrough a first hinge, and the electric spindle is mounted in the swing spindle box; a second hinge is fixed to the front end, above the first hinge, on the milling head box, the servo motor is hingedto the milling head box through the second hinge, one end of an output shaft of the servo motor is arranged in the containing cavity, the ball lead screw is connected to the output shaft of the servomotor, and a ball lead screw nut is hinged to the rear end of the swing spindle box and connected with the ball lead screw; when the servo motor rotates forwards and backwardsbackward to drive the ball lead screw to rotate, the ball lead screw nut moves in the axial direction of the ball lead screw, and therefore the swing spindle box is driven to swing in a vertical plane. The milling head has the advantages that the structure is simple and the vertical and horizontal conversion can be achieved.

Description

technical field [0001] The invention relates to the technical field of machine tool parts, in particular to a vertical-horizontal conversion virtual axis swing angle milling head. Background technique [0002] With the rapid development of industries such as automobiles, national defense, aviation, and aerospace, and the application of new materials such as aluminum alloys, the requirements for processing machine tools are getting higher and higher. Take the more typical aviation aluminum alloy five-axis linkage parts as an example. The technology of this kind of parts requires turning, milling, radial drilling and boring, etc., and most of them are thin-walled parts and high-hardness materials, and the processing accuracy requirements are also very high. High, so when choosing a machine tool, not only the machining accuracy retention, dynamic performance and reliability of the machine tool should be considered, but also the cost of the machine tool should be considered. If...
