Under the normal condition, tool magazine motor 14 can be accomplished specified action according to instruction: just change/reverse and seek cutter spacing, and position signalling is turned back to device board 6, final system can read correct tool magazine positional information; Under the abnormal conditions; When the tool magazine cisco unity malfunction; Existing systems exists and is difficult to the problem judged fast, and promptly owing to tool magazine its reason more complicated when unusual, machining center itself or tool magazine all might have problems; This need be according to the information of machining center screen prompt, and perhaps the maintenance personal rule of thumb judges.

Summary of the invention

Problem and defective to the said system existence; The goal of the invention of the utility model provides a kind of novel structure; The pick-up unit of the Tool Magazine in Machining Centers of failure judgement position rapidly; Promptly this pick-up unit can only be tested tool magazine itself under the situation that breaks away from original system, is normal if tool magazine is worked on this device, can judge that then fault occurs on the machining center; If tool magazine cisco unity malfunction on this device then can utilize this device to carry out further project testing or adjusts, till with the tool magazine operate as normal.

The utility model the technical scheme that will adopt be:

A kind of pick-up unit of Tool Magazine in Machining Centers; Comprise power supply, installing plate and be located at forceful electric power module and the light current module on the installing plate; Power supply is 3 cross streams power supplys, connects forceful electric power module and light current module respectively, and the forceful electric power module is linked to each other successively with the directional contactor group by air switch, fuse and constitutes; The light current module comprises controller and position signal acquisition device; The output terminal of directional contactor group connects the input end of the motor of control tool magazine; The input end of the output terminal link position signal picker of motor; The input end of controller is connected with the output end signal of position signal acquisition device, and the output terminal of controller is connected with directional contactor group signal.

As preferably, described controller is made up of Programmable Logic Controller and human-computer interface module, and human-computer interface module is connected with the Programmable Logic Controller two-way signaling.

The employing such scheme of the utility model has following useful effect: 1. rapid failure judgement position.When the tool magazine work in-process in the heart can't operate as normal, can two signal line on the motor of control tool magazine be connected with this pick-up unit, start this equipment, the failure judgement position is tool magazine or adds an individual center itself rapidly; 2. tool magazine is carried out functional test.Functional test comprises two aspects, and can this tool magazine of first test accomplish the action of machining center requirement: the assigned address rotation is pressed in manually tool magazine order step-by-step rotation, auto state down; It two is to force test, and main test faces the step-by-step rotation mutually, skip one rotates or skip the multidigit rotation, and the test run time, assesses the performance of this tool magazine with this.3. tool magazine is assisted maintenance.Different with simple test; The tool magazine maintenance need be opened the relevant cover plate of tool magazine equipment; Operation is observed, is debugged or changes in action to its inner body, during need send enabling signal through this equipment, come thus certain parts in the tool magazine are carried out field adjustable; Till meeting action request, maintenance provides professional platform to this device to tool magazine.
