Furthermore, the cylinder is provided with a reversing valve, and the reversing valve is electrically connected with the control relay.

Further, the counter is provided with a manual button for operating the air cylinder to clamp the workpiece.

Furthermore, the priority of the signal sent by the counter for controlling the air cylinder to loosen the workpiece is higher than that of the signal sent by the counter for controlling the air cylinder to clamp the workpiece.

The utility model has the advantages that: a leak protection tapping system for lathe, including lathe, proximity switch, counter, anchor clamps, the lathe is provided with the reversal relay of control main shaft reversal, proximity switch set up in the next door of reversal relay is used for the response the operating condition of reversal relay, proximity switch with the counter electricity is connected, anchor clamps are provided with the flexible control relay of cylinder and control cylinder, control relay with the counter electricity links. The utility model discloses a detect the reversal number of times of lathe main shaft to the tapping hole number to the work piece is counted, then with the setting value of counter is compared, thereby whether control fixture opens, reaches the purpose whether the tapping is leaked in the automatic judgement of system. The utility model discloses simple structure goes on easily to the improvement of existing equipment, has practiced thrift time and cost to production efficiency has been improved.

Detailed Description

The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.

As shown in fig. 1 and 2, the leak-proof tapping system for the machine tool comprises a machine tool 1, a proximity switch 3, a counter 4 and a clamp 5, wherein the machine tool 1 is provided with a reversing relay 2 for controlling the main shaft to reverse, the proximity switch 3 is arranged beside the reversing relay 2 and used for sensing the working state of the reversing relay 2, the proximity switch 3 is electrically connected with the counter 4, the clamp 5 is provided with a cylinder 51 and a control relay 6 for controlling the cylinder 51 to stretch and retract, and the control relay 6 is electrically connected with the counter 4.

The utility model is an improvement of the existing machine tool, the counter 4 and the proximity switch 3 for collecting signals for the counter 4 are mainly added, the proximity switch 3 is arranged at one side of the reversing relay 2 which is arranged on the machine tool 1 and used for controlling the reversing of the main shaft, thereby monitoring the reversing times of the main shaft of the machine tool; when the counter is used, a set value, namely the number of holes to be tapped of a workpiece, is manually input by the counter 4, then when tapping is performed, a pulse signal is sent to the counter 4 once when the proximity switch 3 detects that the reversing relay 2 works once, and the counter 4 counts once through plus 1 and is the current value; and, every time the counter 4 counts once, it will perform a numerical comparison, that is, compare whether the current value is equal to the set value, if the current value is less than the set value, the counter 4 will not send a signal, if the current value is equal to the set value, the counter 4 will send a signal to the control relay 6, and the control relay 6 will control the air cylinder 51 to move, so as to open the clamp 5.

The cylinder 51 is provided with a direction change valve 52, and the direction change valve 52 is electrically connected with the control relay 6. The control relay 6 controls the action of the cylinder 51 by controlling the reversing valve 52, the cylinder 51 can be a single-acting cylinder or a double-acting cylinder, and the reversing valve 52 and the control relay 6 matched with different cylinders 51 are different. The counter 4 is provided with a manual button 41 for operating the air cylinder 51 to clamp the workpiece, the manual button 41 sends a signal to the control relay 6 to control the reversing valve 52, the air cylinder 51 can only be operated to clamp the workpiece, and the manual button 41 is mainly used for operating the air cylinder 51 to lock the workpiece when the workpiece is manually clamped. When the manual button 41 is pressed, the counter 4 sends a signal to the control relay 6, when the priority is weaker than the current value which is the set value, the counter 4 sends a signal to the control relay 6, the latter is used for controlling the air cylinder 51 to open a workpiece, and the signal for controlling the air cylinder 51 to open the workpiece is sent out only when the current value which is the set value; therefore, when the current value is less than the set value, the clamp 5 cannot be opened no matter how the manual button 6 is pressed, and when the current value is equal to the set value, the counter 4 may automatically cut off the signal from the manual button 41, and the counter 4 may send a signal to the control relay 6 to control the clamp 5 to be opened.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
