Referring to fig. 2 to 5, the automatic missed-tapping alarm device for radial drilling machine equipment of the present utility model comprises a controller U1, a missed-tapping alarm system, a reverse rotation detection sensor 2 and an elastic device 4 for installing a first proximity switch 10, wherein the missed-tapping alarm system is installed on a drilling machine,

The first proximity switch 10 is fixedly arranged below the drilling spindle handle 1 through the elastic device 4, and a signal output end of the first proximity switch 10 is electrically connected with a second signal input end of the controller U1.
The controller U1 is electrically connected with an operation switch set. The operation switch group comprises a reset alarm switch S1, a stop switch S2, an increase hole number switch S3 and a decrease hole number switch S4, wherein a second control end of the controller U1 is grounded through the reset alarm switch S1, a third control end of the controller U1 is grounded through the stop switch S2, a fourth control end of the controller U1 is grounded through the increase hole number switch S3, and a fifth control end of the controller U1 is grounded through the decrease hole number switch S4.
The switch states of the reset alarm switch S1, the stop switch S2, the hole number increasing switch S3 and the hole number decreasing switch S4 are all normally open states.
The reset alarm switch S1 is used for resetting the manual clearing alarm aggregate count in the controller U1, so that the audible and visual alarm H1 stops acting. The stop switch S2 is used for stopping the drilling machine equipment in the working state in an emergency, so that personnel injury is prevented. The hole number increasing switch S3 is used for increasing the number of holes of the machined workpiece by closing the hole number increasing switch S3 in the case of occurrence of missed tapping. The hole number reducing switch S4 is used for closing the hole number reducing switch S4 when the actual number of the tapping holes is required to be reduced, and the controller U1 controls the tapping drill to reduce the number of the tapping holes, so that the number of the tapping holes is reduced.
The tapping leakage alarm system is electrically connected with the controller U1. The tapping leakage alarm system comprises an audible and visual alarm H1, and the audible and visual alarm H1 is electrically connected with a first control end of the controller U1.
The tapping in-place system comprises a first proximity switch 10 and an elastic device 4 for installing the first proximity switch 10, wherein the elastic device 4 is fixedly installed below the drilling spindle handle 1, and a signal output end of the first proximity switch 10 is electrically connected with a second signal input end of the controller U1.
The elastic device 4 comprises a base 9 and a sliding block 7 used for being in contact with the handle 1 of the drilling machine spindle, a cavity is formed in the base 9, a sliding rod 5 is fixedly installed in the cavity, a spring 6 is sleeved on the sliding rod 5, the sliding block 7 is slidably installed above the cavity through the sliding rod 5, a contact head 8 used for triggering a first proximity switch 10 is arranged at the bottom of the sliding block 7, and the triggering end of the first proximity switch 10 is fixedly installed at the bottom of the base 9.
The drilling spindle handle 1 and the first proximity switch 10 are subjected to hard contact limiting, so that tapping in-place detection is realized. The first proximity switch 10 is mounted in a resilient manner so that the means for triggering the first proximity switch 10 can be reset. In addition, the first proximity switch 10 and the controller U1 form a redundant system, so that tapping of the drilling spindle handle 1 is counted, and the counting accuracy is improved.
The working principle of the utility model is as follows:
As shown in fig. 4, the drill spindle handle 1 has three different angular positions, a "forward rotation", "stop", "reverse rotation", and a "reverse rotation" position is detected by the reverse rotation detection sensor 2. When the inversion of the drill spindle handle 1 triggers the inversion detection sensor 2 each time, the signal output end of the inversion detection sensor 2 outputs an inversion signal to the first signal input end of the controller U1, and the controller U1 controls the counting unit to increment by one after receiving the signal, so that the counter is used as one count in the product processing process.
In continuous production, the calculating time interval of the number of the product machining holes needs to automatically identify the state of 'one workpiece machining end', and the state of 'one workpiece machining end' is used as a demarcation point for starting one workpiece machining operation and the next workpiece machining operation. The method for automatically identifying the end of processing of one workpiece comprises the following steps:
1. The workpiece sensor B1 is arranged on the radial drilling machine equipment, and when the workpiece is removed from the radial drilling machine equipment, the workpiece sensor B1 does not detect a signal, namely, the workpiece sensor B1 recognizes that the machining of one workpiece is finished. The method is suitable for the situation that the workpiece sensor B1 can always detect signals in the processing process;
2. In the workpiece loading and unloading process, the drilling spindle handle 1 is in a stop position, the signal output end of the inversion detection sensor 2 does not output signals to the first signal input end of the controller U1, and when the time of the drilling spindle handle 1 in the stop position is greater than a set value T, the drilling spindle handle 1 is identified as 'one workpiece processing end'. The method is suitable for the situation that the time for clamping the workpiece is longer than the time for processing one hole.
A reference tap Kong Shuzhi N and a time reference value T are preset on the controller U1.
Wherein, starting from the counting unit of the controller U1 being 0, the number of tapping holes in the counting unit is increased by one every time the drilling spindle handle 1 is reversed, so as to obtain the actual number of tapping holes C of a final workpiece.
When "one workpiece processing end" is recognized, the actual number of tapped holes C of one workpiece is compared with the reference Kong Shuzhi N. When the actual tapping hole number C of a workpiece is more or less than the reference Kong Shuzhi N, the first control end of the controller U1 controls the audible and visual alarm H1, the audible and visual alarm H1 gives out audible and visual alarm to prompt that the tapping hole number is abnormal, and at the moment, the reset alarm switch S1 is required to be controlled to reset the manual clearing alarm combination count in the controller U1, and the audible and visual alarm H1 stops acting.
When the actual tapping hole number C of one workpiece is equal to the reference Kong Shuzhi N, the first control end of the controller U1 does not control the audible and visual alarm H1, the audible and visual alarm H1 does not act, and the manual clearing alarm combination count in the controller U1 is automatically reset.
When the drilling spindle handle 1 and the first proximity switch 10 are subjected to hard contact limiting each time, the signal output end of the first proximity switch 10 sends a limiting signal to the controller U1, the limiting value in the counting unit of the controller U1 is increased by one, and finally the actual limiting value K of a workpiece is obtained. Comparing an actual limit value K of a workpiece with an actual tapping hole number C of the workpiece, judging whether tapping of the workpiece is normal or not, and if so, judging that tapping of the workpiece is normal; if the tapping is inconsistent, the tapping of the workpiece is abnormal.
While only the preferred embodiments of the present utility model have been described above, it should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present utility model, and these do not affect the effect of the implementation of the present utility model and the utility of the patent.
