Abstract
The utility model provides a structure for preventing spindle unclamping caused by transmission belt failure on machining equipment. The structure comprises a spindle belt wheel, information sending lugs are arranged on the spindle belt wheel, an inductive switch is arranged at the nearby position, corresponding to the information sending lugs, of the outer side of the spindle belt wheel, the inductive switch is connected with a rotating speed monitor, and the rotating speed monitor is connected with an electrical control system which is used for controlling a motor to rotate. The number of the information sending lugs arranged on the spindle belt wheel is 2-6, and the information sending lugs are distributed at an equal central angle. According to the structure, when unpredictable transmission belt slip or transmission belt fatigue break occurs in the machining process of the machining equipment, the control system stops the feeding process of the current spindle cutter immediately, and meanwhile alarming information is sent out. The whole process is completed automatically, and no intervention of operators is needed.
Description
Technical field
The utility model relates to a kind of structure of causing main shaft to forge a knife because of driving belt fault of preventing on machining apparatus, is particularly suitable for being applied on Metal Cutting Machine Tool, in order to prevent because of the forge a knife generation of accident of the main shaft that driving belt fault causes.
Background technology
Metal Cutting Machine Tool is generally for the equipment of the machining of part, in manufacturing, is widely used.In running, often there is a problem in this kind equipment, when occurring in the process of feeding machined part exactly that belt creep or fatigue fracture are this and can not predict fault in advance, main shaft actual speed can decline to a great extent, and now main shaft and cutter are still continuing feeding machined part, thereby cause the main shaft accident of forging a knife.The main shaft accident of forging a knife can cause main shaft damage, cracking of cutter, part to scrap, and even operative employee's personal safety is also threatened.
Summary of the invention
The purpose of this utility model is a kind of structure of causing main shaft to forge a knife because of driving belt fault of preventing on machining apparatus of design, main shaft actual speed in machined part process is detected, when driving belt skids or can the speed of mainshaft decline to a great extent during fatigue fracture, control system stops the feeding process of main axle cutter immediately, thereby has prevented the forge a knife generation of accident of main shaft.
The technical solution of the utility model: of the present utility model preventing on machining apparatus comprises spindle pulley because driving belt fault causes the structure that main shaft is forged a knife, on spindle pulley, establish the projection of posting a letter, near location arrangements inductive switch spindle pulley outside, correspondence are posted a letter projection, inductive switch is connected with Speed Controller, and Speed Controller is connected with the electric control system that control electric machine rotation and slide unit move.
The projection of posting a letter of establishing on described spindle pulley has 2～6, waits central angle to arrange.
Described inductive switch is induction approach switch.
Advantage of the present utility model: occur in the process of machining equipment that unpredictable driving belt skids or during fatigue fracture, control system stops the feeding process of current main axle cutter immediately, provides warning message simultaneously.Whole process completes automatically, does not need operating personnel's intervention.
Accompanying drawing explanation
Fig. 1 is theory of mechanics schematic diagram of the present utility model.
Fig. 2 is spindle pulley in Fig. 1, the position relationship side view of the projection of posting a letter, inductive switch.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated.
Fig. 1, Fig. 2 are theory of mechanics schematic diagrames of the present utility model: in figure: 1-spindle pulley, 2-post a letter projection, 3-inductive switch, 4-Speed Controller, 5-motor electric control system, 6-motor pulley, 7-electric rotating machine, 8-belt, 9-main shaft, 10-cutter, 11-slide unit, 12-equipment guide rail.
The utility model is established the projection 2 of posting a letter on spindle pulley 1, near location arrangements inductive switch 3 spindle pulley 1 outside, correspondence are posted a letter projection 2, inductive switch 3 is connected with Speed Controller 4, and Speed Controller 4 is connected with the electric control system of controlling electric rotating machine.
The central angles such as the projection 2 of posting a letter of establishing on described spindle pulley 1 has 2～6, even number are arranged.
Described inductive switch 3 is induction approach switchs.
Described Speed Controller 4 refers to and is built-in with numeric door on-off circuit, and has the checkout gear of frequency computation part function.
As depicted in figs. 1 and 2, at machine, add in the automatic machine process of kind equipment, electric rotating machine 7 makes main shaft 9 and cutter 10 rotations by the transmission of motor pulley 6, belt 8, and main shaft 9 and cutter 10 march forward to the machining of carrying out part under the driving of slide unit 11 simultaneously.The projection 2 of posting a letter being arranged on spindle pulley 1 also rotates with same rotating speed, because the projection 2 of posting a letter is different from mounting plane height, the digital pulse signal that makes inductive switch 3 can send 0-1-0-1 is sent to Speed Controller 4, Speed Controller 4 according to the parameter setting (comprise signal type, the number of slugs of posting a letter, time base value, safe speed of rotation setting value etc.), can process the digital pulse signal of 0-1-0-1, calculate the current actual speed value of main shaft, and constantly and secure setting compare.While there is the faults such as belt creep or fatigue fracture in the process of feeding machined part, main shaft actual speed can decline to a great extent, main shaft actual speed value can be lower than secure setting, and Speed Controller 4 can be sent " rotating speed is low " signal to the input block of electric control system 5.When electric control system 5 receives Speed Controller 4, send after " rotating speed is low " signal, by control program, carry out safe handling, stop immediately the feeding process of current main axle cutter, provide warning message simultaneously.
When there is the prior unpredictable situation of this operating personnel of spindle drive belt creep or fatigue fracture, control system can stop current machine process immediately automatically, thereby has effectively prevented the forge a knife generation of accident of the main shaft causing therefrom.
