Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a leakage-proof tapping system for a machine tool, which can avoid the phenomenon of leakage tapping of workpieces from the source by self-checking in a tapping process.

The technical scheme adopted by the invention for solving the technical problems is as follows: 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 one side 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 fixed in the workstation of lathe, anchor clamps are provided with cylinder and control the control relay of cylinder action, control relay with the counter electricity is connected.

Further, the counter is provided with a display screen, and the counter is an addition counter.

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 invention has the beneficial effects 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. According to the invention, the number of the tapping holes of the workpiece is counted by detecting the number of times of reversal of the spindle of the machine tool, and then the counted number is compared with the set value of the counter, so that whether the clamp is opened or not is controlled, and the purpose of automatically judging whether tapping is missed or not by a system is achieved. The invention has simple structure, is easy to improve the prior equipment, saves time and cost and improves the production efficiency.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific examples, which are 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 invention is an improvement of the existing machine tool, and is mainly added with the counter 4 and the proximity switch 3 for collecting signals for the counter 4, wherein the proximity switch 3 is arranged at one side of a reversing relay 2 which is arranged on the machine tool 1 and used for controlling the reversing of the main shaft, so that the number of times of the reversing of the main shaft of the machine tool is monitored; 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.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
