Abstract
The utility model provides a self-detection tapping machine which comprises a machine body, a feeding unit and a tapping unit, wherein the feeding unit and the tapping unit are arranged on the machine body. The tapping unit comprises a tapping machine body and a screw tap installed on the tapping machine body. The self-inspection tapping machine is characterized in that the machine body is further provided with a detection unit, the detection unit comprises a light sensor, and the light sensor is arranged nearby the screw tap; the light sensor controls connection and disconnection of a power supply circuit of the feeding unit through a contactor. The self-detection tapping machine detects the condition of the screw tap through the light sensor, stopping instructions are sent to the feeding unit and the tapping unit in time through the contactor, the defective rate is reduced, and the machining reliability is improved.
Description
Technical field
The utility model relates to Machining Technology field, particularly a kind of self check tooth machining unit.
Background technology
In the hole of workpiece, process internal thread and be called tapping, also cry tapping, its machining tool is called screw tap or screw tap.In the tapping process to metal, screw tap is loss very easily, and the bending that may the deflect problems such as even rupture will cause product to leak tooth if find not in time, equipment card pauses, and even production accident, greatly affects process velocity.
Traditional numerical control drilling can be realized tapping function, equipment component also has self-checking function, yet most of equipment is by the tooth of processing work being detected to grasp the situation of processing, such as Chinese patent CN201120180550.8 has disclosed a kind of " automatic tapping machine ", its tooth checkout gear after by tapping device and drawing mechanism have been realized carrying out continuously that product detects and substandard products screen, improved operating efficiency, reduced labour cost, yet this equipment can only the unstable indivedual substandard products problems brought of resolution system.When screw tap goes wrong, equipment cannot be got rid of this problem voluntarily, still can continue to export substandard products, the waste that brings raw material.
Therefore, be necessary to provide a kind of new self check tooth machining unit to solve the above deficiency of prior art.
Utility model content
Main purpose of the present utility model is to provide a kind of self check tooth machining unit that can make a response to screw tap problem in advance.
The utility model is achieved through the following technical solutions above-mentioned purpose: self check tooth machining unit, comprise board and be located at feeding unit and the tapping unit on described board, described tapping unit comprises tooth machining unit body and is installed on the screw tap on described tooth machining unit body, it is characterized in that: on described board, be also provided with detecting unit, described detecting unit comprises light sensor, and described light sensor is located near described screw tap; Described light sensor is controlled the break-make of described feeding unit power supply circuits by contactor.
In some embodiments, described detecting unit also comprises cylinder, and described cylinder is installed on described board, and described light sensor is installed on described cylinder head.
Preferably, described feeding unit power supply circuits are normally-closed contact in the contact at described contactor place.
Preferably, described light sensor is controlled the break-make of described tooth machining unit body power supply circuits by contactor.
Preferably, the power supply circuits of described tooth machining unit body are normally-closed contact in the contact at described contactor place.
Preferably, the power supply circuits of described tooth machining unit body are normally-closed contact in the contact at described contactor place.
Preferably, the power supply circuits of described alarm are normally opened contact in the contact at described contactor place.
Compared with prior art, the beneficial effects of the utility model are:
1, the state of light sensor direct-detection screw tap can cut off at once the power supply of feeding unit and tooth machining unit body when pinpointing the problems by contactor, prevention equipment continues running, in order to avoid more multi-work piece is scrapped;
2, light sensor is controlled advance and retreat by cylinder, when each screw tap machine return after light sensor just approach screw tap and detect, prevent that first light sensor from bumping against tooth machining unit body, second make to examine time difference method more accurate, prevent from being subject to ambient light affect and judge by accident;
3, contactor is also controlled an alarm, and after screw tap problem occurs, contactor not only control appliance is shut down, and also will remind in time workman on the scene to change screw tap, and problem is got rid of as early as possible.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model self check tooth machining unit;
Fig. 2 is the circuit diagram under the utility model self check tooth machining unit normal operating conditions.
In figure:
1, board;
2, feeding unit;
3, tapping unit, 31, tooth machining unit main body, 32, screw tap;
4, detecting unit, 41, light sensor, 42, cylinder;
5, contactor;
6, alarm.
The specific embodiment
As shown in Figure 1, the utility model is a kind of self check tooth machining unit, comprises board 1, feeding unit 2, tapping unit 3 and detecting unit 4.Feeding unit 2, tapping unit 3 and detecting unit 4 are all located on board 1.Tapping unit 3 comprises tooth machining unit body 31 and is installed on the screw tap 32 on tooth machining unit body 32, feeding unit 2 is through screw tap 32 belows, detecting unit 4 comprises light sensor 41 and cylinder 42, cylinder 42 is installed on board 1, and light sensor 41 is installed on cylinder 42 heads and is positioned at screw tap 32 sides.
With reference to figure 2, feeding unit 2, tooth machining unit body 31, alarm 5, light sensor 41 are parallel to power supply, whether the circuit of feeding unit 2, tooth machining unit body 31 and alarm 5 is connected and is subject to contactor 5 controls, wherein the circuit of feeding unit 2 and tooth machining unit body 31 adopts normally-closed contact in contactor 5 positions, alarm 5 at circuit, in contactor 5 positions, adopt normally opened contacts, contactor 5 is subject to the control of light sensor 41.
During normal work, contactor 5 makes the circuit of feeding unit 2 and tooth machining unit body 31 in on-state, and alarm 5 circuit are in off-state.At each workpiece, machine exhaust hood 42 and control light sensor 41 near screw tap 32, if screw tap 32 not detected has extremely, cylinder 42 is return, prevent that light sensor from bumping against tooth machining unit body 31 or judging by accident because ambient light changes, feeding unit 2 and tooth machining unit body 31 keep normal work, and alarm 5 is not reported to the police; If it is abnormal that light sensor 41 detects screw tap 32, by contactor 5, change circuit state, make the circuit of feeding unit 2 and tooth machining unit body 31 disconnect, processing suspends, prevent more times product, alarm 5 closings of circuit, remind workman on the scene to process in time screw tap 32 problems simultaneously.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
