Abstract

The utility model discloses a testing tool for detecting the height of a metal stamping bur. A micro electricity perception circuit is connected with a micrometer. When a movable detection head of the micrometer is contacted with the bur spire on the measured element, the bur conducts the electricity to generate a signal. The electric signal is magnified through the micro electricity perception circuit to cause an LED to emit light, a sounding element to send out sound and a digital display screen to show the value, and the reading of the micrometer is read out, and then the height of the bur is calculated. The utility model has the advantages of high accuracy of detection of metal stamping bur, simple and convenient operation, small size, compact structure, and portability. The utility model is suitable for production field.

Description

Metal punching burr detector

The utility model relates to a kind of survey instrument, particularly relates to a kind of instrument that detects the metal burr height.

The main means that detect sheet metal punching workpiece burr at present in commercial production are to measure burr height with general milscale, this method in measuring process, is often pressed burr short entirely with feel pressure, cause to measure and forbidden, another kind method is with optical instrument burr height to be carried out optical projection, measures the optical projection height of burr then, is converted into burr height again, though this method precision height, but complicated operation uses inconvenience, is difficult to be implemented in the production scene and uses.

The purpose of this utility model provides a kind of easy, highly sensitive, easy to use metal punching burr detector.

The utility model is achieved in that metal punching burr detector, the magnetic support of milscale is that magnetic material is made, the fixed test head is inlaid in the magnetic support, the workplace of fixed test head and magnetic support is in the same plane, and with the motion detection head on the milscale be mutually insulated, the handle of milscale is that insulating material is made, little inductance is housed in the handle knows circuit, little inductance knows that signal input part B of circuit links to each other with motion detection head on the milscale, and little inductance knows that another signal input part W of circuit links to each other with metal crocodile clip and fixed test head.Little inductance is known on the K switch of circuit and the surface that display device is contained in handle.Magnetic support can be a magneto, also can be electromagnetic type.

The utility model is known circuit owing to connected a little inductance on milscale, when needs are measured the height of measured piece burr, connect little inductance and know circuit, measured piece need be surveyed burr to be placed on the magnetic support of magnetic towards a milscale motion detection direction, can make measured piece closely contact magnetic support, reduce error, the rotation milscale, milscale motion detection head is moved to the measured piece burr, when the first contact burr of milscale motion detection pinnacle, make little inductance know circuit turn-on, the conducting electric signal shows by display device after amplifying.At this moment, the milscale that stops the rotation is read the reading of milscale or digital display screen, deduct the thickness of measured piece, promptly draw burr height, so accuracy of detection is very high, method of operating is simple, and is easy to use, because little inductance knows that circuit is arranged in the intracavity of handle, the switch of circuit, light emitting diode, sounding component and digital display screen are arranged on the surface of handle, therefore, this detector, volume is small and exquisite, and compact conformation is easy to carry and uses in the production scene.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the principle schematic of the utility model embodiment one;

Fig. 3 is the principle schematic of the utility model embodiment two.

As shown in Figure 1: metal punching burr detector comprises milscale 1, motion detection 6, the magnetic support 7 that magnetic material is made, the handle 4 that insulating material is made, little inductance knows that circuit 5 is arranged in the handle 4, little inductance knows that the K switch of circuit 5 and display device 2 are arranged on the surface of handle 4, be convenient to operation, display device 2 can be made up of light emitting diode D and sounding component Y and digital display screen H, also but wherein any one works independently, metal crocodile clip 8 knows that by lead and little inductance the W end of circuit is connected, W end is connected and fixed detection head 9, and fixed test 9 is contained on the magnetic support 7.And fixedly gauge head 9 outer is with insulating material 11 fixedly gauge head 9 and magnetic support 7 insulate with miscellaneous part.

Embodiment one, Fig. 2 shows the movable gauge head 6 that the little inductance of the utility model is known circuit 5 and milscale 1, the fixing annexation of gauge head 9, measured piece is placed on the magnetic support 7 that magnetic material makes, the burr of measured piece is towards the motion detection of milscale 16, signal input part B that little inductance is known circuit and the motion detection of milscale 16 links to each other, little inductance knows that another signal input part W of circuit is connected on fixedly on the gauge head 9, fixed test 9 is contained on the magnetic support 7, during detection, connect K switch, rotation milscale 1, motion detection 6 moves down, when motion detection 6 touches the pinnacle of the burr A on the measured piece, the burr conduction produces electric signal i, electric signal i makes lumination of light emitting diode, after the operator sees led lighting after triode G amplifies, milscale 1 promptly stops the rotation, read reading, the reading of reading deducts the thickness of measured piece, draws burr height.

Embodiment two, Fig. 3 shows the little inductance of the utility model and knows circuit 5 and the movable gauge head 6 of milscale 1, the fixing annexation of gauge head 9, when measured piece in process, when scribbling megohmite insulant, clamp measured piece with metal crocodile clip 8, make clip and metal conduction, other can measure the height of burr on the measured piece as shown in Figure 3.The display device 2 that this embodiment has adopted light emitting diode D and sounding component Y and digital display screen H to form is convenient to observe operation more.
