Abstract
The utility model relates to an operating handle alarm protection device of a machine tool. The protection device comprises an alarm device, an alarm switch and a handle seat. The alarm switch is fixed on a shell of the machine tool, a button of the alarm switch is connected with the handle seat, the alarm switch is provided with at least one normally open contact and at least one normally closed contact, the normally open contact of the alarm switch is connected in a starting loop of the machine tool in series, and the normally closed contact of the alarm switch is connected with a power supply to form an alarm loop after being connected with a second normally open contact of a starting switch of the machine tool and the alarm device in series. The operation handle alarm protection device of the machine tool can effectively prevent the machine tool from being started due to an operation handle of the machine tool is not evacuated from the installing position in the actual production, thereby avoiding equipment damage and human injury. The operating handle alarm protection device has the characteristics that: the structure is simple, parts are less and the cost is low; the protection device can be applied to not only the modification of the present machine tool, but also the newly-developed machine tool; and the application prospect is wide.
Description
Technical field
The utility model relates to a kind of warning device, relates in particular to a kind of machine operation handle warning protector.
Background technology
Behind lathe (as: lathe, milling machine etc.) the operating grip clamping finished piece(s), must withdraw from the installation site, this has become important of safety operation.Because, when lathe operates, will cause personal injury and device damage if do not withdraw operating grip.
In practical operation, people forget sometimes operating grip are withdrawn.And existing machine tool also can start, move when not withdrawing operating grip, therefore has great potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of machine operation handle warning protector, after this warning protector is installed, if the machine operation handle is not put to assigned address, just can't start lathe, thereby can avoid in actual production, not withdrawing, cause the problem of personal injury and device damage from the installation site because of the machine operation handle.
The utility model is achieved through the following technical solutions: a kind of machine operation handle warning protector, comprise an alarm, an alarm switch and a handle set, described alarm switch is installed on the lathe shell, the button of alarm switch is connected with handle set, alarm switch has at least one normally opened contact and at least one normally-closed contact, the normally opened contact of alarm switch is serially connected with lathe and starts in the loop, second normally opened contact of the normally-closed contact of alarm switch and lathe starting switch and described alarm connect afterwards and power supply is connected to form alarm circuit.
Its principle is as follows: if operating grip is not put to handle set, alarm switch just can not move, its normally-closed contact is kept closed, normally opened contact keeps off-state, at this moment, if press the lathe starting switch, will connect alarm circuit, alarm will send warning, normally opened contact because of alarm switch is serially connected with in the lathe startup loop, so lathe can not start simultaneously.Have only operating grip is put to handle set, just can depress the button of alarm switch, make the normally opened contact of alarm switch be in closure state, normally-closed contact is in off-state, at this moment, press the lathe start button, lathe starts the loop and connects, lathe normally starts, and because the normally-closed contact of alarm switch is off-state at this moment, so alarm circuit disconnects, alarm can not send warning.
This machine operation handle warning protector can effectively prevent from the actual production not withdraw from the installation site because of the machine operation handle and just start lathe, thereby can avoid causing device damage and personal injury.It is simple in structure, and part is few, and cost is low, and the lathe that can be applied to the transformation of existing lathe and newly develop has a extensive future.
Description of drawings
Fig. 1 is the circuit theory diagrams of present embodiment machine operation handle warning protector;
Fig. 2 is the structural representation of its handle set;
Fig. 3 is the structural representation after being placed on handle on the handle set.
The specific embodiment
The utility model provides a kind of machine operation handle warning protector, and it comprises alarm switch and alarm, by the interlocking realization of alarm switch and lathe starting switch.Further describe below in conjunction with accompanying drawing.
With reference to Fig. 1-3, this machine operation handle warning protector comprises an alarm 1, an alarm switch and a handle set 2, described alarm switch is installed on the lathe shell 4, the button 5 of alarm switch is connected with handle set 2, alarm switch has at least one normally opened contact SB31 and at least one normally-closed contact SB32, the normally opened contact SB31 of alarm switch is serially connected with lathe and starts in the loop, the second normally opened contact SB22 of the normally-closed contact SB32 of alarm switch and lathe starting switch and described alarm 1 connect afterwards and power supply is connected to form alarm circuit.SB1 is the Machine Tool Circuit power main switch among Fig. 1, and first normally opened contact SB21 of lathe starting switch and relay K M1 constitute latching circuit.
Handle set of the present utility model and alarm switch also can adopt below in conjunction with mode: handle set has a pedestal, have the groove that is used to place handle on the pedestal, handle set is fixedlyed connected with the button of alarm switch, only need this moment alarm switch is installed on the lathe shell 4, handle set separates with the lathe shell.Perhaps further, also the button of handle set and alarm switch can be made of one.
In the present embodiment, the pedestal of handle set 2 is circular pedestal, in the practical application, also can make strip pedestal or other different shape.
Claims (4)
1, a kind of machine operation handle warning protector, it is characterized in that: comprise an alarm, an alarm switch and a handle set, described alarm switch is installed on the lathe shell, the button of alarm switch is connected with handle set, alarm switch has at least one normally opened contact and at least one normally-closed contact, the normally opened contact of alarm switch is serially connected with lathe and starts in the loop, second normally opened contact of the normally-closed contact of alarm switch and lathe starting switch and described alarm connect afterwards and power supply is connected to form alarm circuit.
2, machine operation handle warning protector according to claim 1, it is characterized in that: described handle set has a pedestal, have the groove that is used to place handle on the pedestal, a through hole is arranged at the bottom of groove, handle set is installed on the lathe shell, and the described through hole that the button of described alarm switch passes on the handle set protrudes upward.
3, machine operation handle warning protector according to claim 1, it is characterized in that: described handle set has a pedestal, has the groove that is used to place handle on the pedestal, and this handle set is fixedlyed connected with the button of alarm switch.
