Automatic tool setting device and numerical control machining machine head

Abstract

The invention discloses an automatic tool setting device which comprises a retractor device, a triggering sensing device and a tool controller. The triggering sensing device is arranged on the retractor device and moves in the stretching direction of the retractor device under the acting force of the retractor device; the tool controller is connected with the triggering sensing device and collects data fed back by the triggering sensing device to modify the position of a numerical control tool according to the data. By means of the automatic tool setting device, the triggering sensing device is in contact with the surfaces of machined materials by controlling the retractor device to determine the distance between the triggering sensing device and the surfaces of the machined materials, then determined distance parameters are fed back to the tool controller to enable the tool controller to conduct parameter modification on the numerical control tool according to the distance parameters, positional deviations of the numerical control tool are modified, the automatic tool setting function of the numerical control tool is further achieved, the distance between the tool and the machined materials is accordingly and effectively guaranteed, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tool control, in particular to an automatic tool setting device and a numerical control machining head. Background technique [0002] In the field of CNC machine tools, when processing materials, whenever the processing materials are fixed on the processing table, the surface position of the processing materials must be known, so that the CNC tools can be processed effectively. In this context, there is The step of tool setting for the CNC tool is shown, that is, the position of the CNC tool is corrected. [0003] At present, there are two traditional tool setting methods, one is completely manual tool setting, that is, the tool setting is realized manually with the help of paper or a tool setting block, and specifically, the tip of the CNC tool is pressed against the paper or the tool setting block The advantage of this method of tool setting is that it is simple, but the disad...

Problems solved by technology

[0003] At present, there are two traditional tool setting methods, one is completely manual tool setting, that is, the tool setting is realized manually with the help of paper or a tool setting block, and specifically, the tip of the CNC tool is pressed against the paper or the tool setting block The advantage of this method of tool setting is that it is simple, but the disadvantage is that it must be done manually and cannot be done automatically; the other is automatic laser tool setting, that is, the position of the CNC tool is corrected by measuring the distance with the laser. The advantage of the knife method is that it realizes automation, and has the advantages of fast speed and good accuracy, but the disadvantage is that it is expensive, has high environmental requirements, and cannot have dust pollution.

[0004] It can be seen from the above that although the traditional tool setting method can play a role in tool setting, there are still many deficiencies in the traditional tool setting method. And the tool setting device that has low requirements on the environment and can realize automatic measurement has become a problem that the industry needs to solve urgently.
