Abstract

The utility model relates to a novel belt transmission device. The novel belt transmission device comprises a driving wheel, a belt, a driven wheel and an outage detecting device, wherein the driven wheel is connected with the driving wheel through the belt, and the outage detecting device is located on one side of the driven wheel and connected with the driven wheel. The novel belt transmission device can monitor the condition of the belt by monitoring the operation condition of the driven wheel, the situation that a machine tool machines workpieces in the process that a main shaft does not rotate or is in a stalling state is avoided, and safety of the machine tool is improved. The structure is simple, the novel belt transmission device is easy to use, cost is low, and the principle is simple.

Description

A kind of novel belt drive unit
Technical field
The utility model relates to a kind of novel belt drive unit.
Background technology
Traditional belt transmission is made up of driving wheel 1, driven pulley 2 and belt 3, as shown in Figure 1 and Figure 2.Driving wheel 1 generally links to each other with the motor equal power device provides power, execution units such as driven pulley 2 general connection main shafts.General rotating speed of motor is all fixed, and the different rotating speeds of wanting to realize main shaft will lean on driving wheel 1 recently to realize with driven pulley 2 different diameters.Belt 3 then is the tie of transferring power between the two.
In actual use in order to guarantee the use safety of lathe, usually the parts that run up need be closed, but so cause machine operation personnel's observation constant, when belt 3 ruptures because of a variety of causes, if can't in time find, can cause at machine tool chief axis does not have processing work under the situation of rotation, causes tool damage, even workpiece consequence such as fly out.
The utility model content
Technical problem to be solved in the utility model provides a kind of electrical system by lathe and detects the situation of belt fracture and the novel belt drive unit of reporting to the police automatically, avoids lathe not rotate or processing work in the process in stall just at main shaft.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of novel belt drive unit, comprise driving wheel, belt, driven pulley and outage detection device, described driven pulley is connected with described driving wheel by described belt, described outage detection device is positioned at a side of described driven pulley, and is connected with described driven pulley.
The beneficial effects of the utility model are: the utility model can be monitored the situation of belt by detecting the working order of driven pulley, avoids lathe not rotate or processing work in the process in stall just the security that has improved lathe at main shaft.Simple in structure easy-to-use, with low cost, principle is simple.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described outage detection device is proximity transducer.
Further, described proximity transducer is square proximity transducer or cylindrical proximity transducer.
Further, the inwall of described driven pulley is provided with projection.
Further, the quantity of described projection is two, and described two projectioies are oppositely arranged at the inwall of described driven pulley.
Description of drawings
Fig. 1 is the structural representation of traditional belt drive unit;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the structural representation of the novel belt drive unit of the utility model;
Fig. 4 is another structural representation of the novel belt drive unit of the utility model;
Fig. 5 is the structural representation of the driven pulley of the novel belt drive unit of the utility model;
In the accompanying drawing, the list of parts of each label representative is as follows:
1, driving wheel, 2, driven pulley, 3, belt, 4, proximity transducer, 5, projection.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not for limiting scope of the present utility model.
A kind of novel belt drive unit, as shown in Figure 3, Figure 4, comprise driving wheel, belt, driven pulley and outage detection device, described driven pulley is connected with described driving wheel by described belt, described outage detection device is positioned at a side of described driven pulley, and is connected with described driven pulley.
Described outage detection device is proximity transducer 4.
Described proximity transducer 4 is square proximity transducer or cylindrical proximity transducer.
As shown in Figure 5, the inwall of described driven pulley 2 is provided with projection 5.Described protruding 5 quantity is two, and described two projectioies 5 are oppositely arranged at the inwall of described driven pulley 2.
Described proximity transducer 4 also can be described as near switch.
As shown in Figure 4, proximity transducer 4 links to each other with the Machine Tools Electric system, detects the projection 5 on the driven pulley 2.When driven pulley 2 normal rotation, the break-make frequency of proximity transducer 4 should be one increases fixing then value gradually after the lathe startup.When belt 3 ruptured before startup, the break-make frequency of proximity transducer 4 was zero.When belt 3 in use ruptures, the trend that the break-make frequency of proximity transducer 4 can occur reducing.Be zero or during the trend that reduces, electrical system can trigger alarm and reminding machine operation personnel or directly stop the operation of lathe in the frequency of occurrences, so just avoided lathe not rotate or processing work in the process in stall just at main shaft.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
