The present invention relates to a stopper control device having a work leakage prevention function during a bolt torque operation, which can prevent a missing work when tightening a bolt or nut by using a torque wrench. The present invention relates to a stopper control device having a prevention function during bolt torque operation, which prevents the omission of work by preventing the stopper from descending and preventing the following subsequent work without proceeding the torque work.

Conventionally, when torqueing a bolt or nut through a torque wrench, there is a case where a 'work missing' occurs in which the wrench does not work properly even though the workpiece is set correctly due to carelessness or mistake. There are many problems, such as a loss of a lot of working time, a decrease in productivity, breakage of various parts, and the like.

The present invention has been made to solve the conventional problems as described above, the object of which is to reduce the work time and mechanical apparatus by controlling the stopper to prevent the work leakage during the tightening of the bolt or nut through the torque wrench The present invention provides a stopper control device having a work leakage prevention function during bolt torque operation that can prevent breakage and improve productivity.

DETAILED DESCRIPTION Hereinafter, the most preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention.

1 is a block diagram of a stopper control device having a work leakage prevention function during bolt torque operation according to an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a torque wrench for fastening the bolts 12 of the work object 11 set on the worktable 13, and checking the presence or absence of the torque work on the upper part of the counter 3 as described below. A check switch (2) for shearing is installed.

In addition, reference numeral 3 denotes a counter provided on one side of the front surface of the control panel 14, which enables to set the quantity of torque work and count the quantity of work.

In addition, reference numeral 4 is a timer provided on the front surface of the control panel 14 to allow setting of the working time before the torque operation.

In addition, reference numeral 5 is a stopper supported by the pneumatic cylinder (5a) on one side of the work table 13, ascends when the workpiece 11 is injected, and descends when the torque work is completed.

In addition, reference numeral 6 denotes a warning lamp installed on one side of the lower panel of the control panel 14, and is turned on when the work object is inserted, and turned off when the torque work is completed.

Reference numeral 7 denotes an air cylinder which is installed on the upper part of the control panel 14 and lifts the control panel 14 and the torque wrench 1, and is lowered by the timer 4, and is raised when the torque operation is completed. .

In addition, reference numeral 8 denotes a balance spring installed on one side of the inner side of the control panel 14 to stably support the rising and falling of the torque wrench 1.

In addition, reference numeral 9 is a completion switch installed on one side of the inside of the control panel (14), it detects the completion of the torque operation to raise the air cylinder (7).

Finally, reference numeral 10 denotes a sensing switch installed at one side of the upper end of the work table 13 to detect the input of the work object 11.

In the present invention configured as described above, when the torque operation as much as the amount set in the counter (3) is not made, the stopper (5) is not lowered so that the omission of the operation can be prevented. When described as follows.

In the present invention, when the workpiece is put into the workbench 13, the sensing switch 10 detects this, whereby the stopper 5 is raised and at the same time the warning light 6 is turned on.

When the preparation necessary for the other torque operation is completed and the time set in the timer 4 has elapsed, the torque wrench 1 together with the air cylinder 7 is lowered to the working position, and each bolt of the workpiece 11 The torque operation in which 12 is fastened through the torque wrench 1 is in progress.

Whenever a single torque operation is performed with the torque wrench 1, the confirmation switch 2 detects the result and transfers the result to the counter 3, and the torque operation as much as the quantity set in the counter 3 is completed. When the stopper (5) is lowered at the same time the warning light (6) is turned off.

By the way, when the torque operation as much as the number set in the counter (3) is not made, the stopper (5) does not fall, and subsequent work is not made accordingly.

Meanwhile, when the torque operation is completed and the torque wrench 1 is released, the balance spring 8 pulls up the torque wrench 1, and the completion switch 9 detects this and the air cylinder 7 is raised. Return to original ready state.

As described above, the present invention is to prevent the omission of the torque work by preventing the stopper from descending when the torque work for the quantity set in the counter 3 is not made so that subsequent work is not performed. According to the present invention, it is possible to eliminate the loss of working time and to perform more efficient torque work, thereby increasing productivity and reducing work cost.
