Three-axis positioning system of numerical control gantry flange drilling machine

Abstract

The invention discloses a three-axis positioning system of a numerical control gantry flange drilling machine, the three-axis positioning system is arranged on a machining platform of the numerical control gantry flange drilling machine in a spanning manner, the three-axis positioning system comprises Y-axis guide beams symmetrically arranged on two sides of the machining platform, and an X-axis cantilever beam connected with an X-axis sliding seat in a sliding manner along the horizontal transverse direction; the bottom of the X-axis cantilever beam is connected to the Y-axis guide beam in a sliding mode in the horizontal longitudinal direction, the back face of the X-axis sliding base is connected to the X-axis cantilever beam in a horizontal sliding mode, the front face of the X-axis sliding base is connected with the Z-axis cantilever in a lifting sliding guiding mode, and the X-axis sliding base is supported by the three-axis positioning system in a stepped sliding mode at the planes and the depth positions in different directions. The Y-axis guide beam is arranged on the X-axis cantilever beam to improve the sliding bearing capacity of the X-axis sliding seat on the X-axis cantilever beam, the Y-axis guide beam integrates the sliding guide function of the X-axis cantilever beam, the power support function of the X-axis cantilever beam and the chip removal and slag discharge function, the structure is simple, and implementation is easy.

Description

technical field [0001] The invention relates to the technical field of drilling machinery, in particular to a three-axis positioning system of a numerically controlled gantry flange drilling machine. Background technique [0002] In the prior art, the sliding connection contact points of the X-axis sliding seat of the gantry flange drilling machine and the X-axis cantilever beam are mostly on the same plane. In the above design, the X-axis sliding seat only serves as the Z-axis cantilever support function. It bears less force, and a tool magazine is fixed at one end of the X-axis cantilever beam. Every time a tool is changed, the X-axis sliding seat needs to slide to the position of the tool magazine to change the tool, and then the X-axis sliding seat slides to the predetermined processing position. Provide guidance for the Z-axis cantilever lifting, this structure makes the X-axis slide seat do not need to bear excessive load, but in order to improve processing efficiency,...

[0002] In the prior art, the sliding connection contact points of the X-axis sliding seat of the gantry flange drilling machine and the X-axis cantilever beam are mostly on the same plane. In the above design, the X-axis sliding seat only serves as the Z-axis cantilever support function. It bears less force, and a tool magazine is fixed at one end of the X-axis cantilever beam. Every time a tool is changed, the X-axis sliding seat needs to slide to the position of the tool magazine to change the tool, and then the X-axis sliding seat slides to the predetermined processing position. Provide guidance for the Z-axis cantilever lifting, this structure makes the X-axis slide seat do not need to bear excessive load, but in order to improve processing efficiency, the tool magazine of the gantry drilling machine can also be transferred to the X-axis slide seat, which can avoid the X-axis slide seat The problem of reciprocating tool change and prolonging the processing time, however, this improvement will inevitably increase the bearing load of the X-axis slide seat. In the prior art, the sliding connection structure between the X-axis slide seat and the X-axis cantilever beam located on the same plane is difficult to bear the Z The overall weight of the axis cantilever and tool magazine

[0003] In addition, the gantry flange drilling machine in the prior art has a single Y-axis guide beam structure and no auger, and often only has the sliding support and power supply functions of the X-axis cantilever beam, and does not have the cleaning of drilling debris. Cleaning function

However, most of the gantry flange drilling machines in the prior art collect and clean debris manually, and it is difficult to realize the automatic debris cleaning function. Once the manual cleaning is not in place or the cleaning is not timely, it is easy to cause iron chips and debris to enter the Y-axis guide The sliding connection between the beam and the X-axis cantilever beam will cause the accuracy of the drilling machine to drop, and in severe cases, the X-axis cantilever beam will be stuck
