Preferably, the fixed limiting device in the other side of the laser diameter measuring instrument, the limiting device includes being horizontally mounted Two rollers and two vertically-mounted rollers, two rollers are there are gap so that plug passes through.

Preferably, the second roller bearing, two the second roller bearings and the first roller bearing are respectively set at left and right sides of first roller bearing Line between three center forms an isosceles triangle.

Preferably, second roller bearing is fixed on the inside of shell, and length is arranged on the side wall of the front and rear sides of the shell Shape hole, the both ends of second roller bearing are respectively fixedly connected with screw rod, and both ends screw rod is each passed through the elongated hole of two sides and passes through spiral shell Second roller bearing is fixed on the inside of shell by mother.

Preferably, the supporting table includes pedestal, support column and erecting bed, and the support column upper and lower ends are fixed respectively Connect erecting bed and pedestal.

The utility model provides a kind of diameter of mandrel, intensity detecting device, can replace the artificial mandril strength and straight realized The detection of diameter, saves manpower, improves work efficiency, and detection while realizing mandril strength and diameter is greatly saved Manually, and detection effect is relatively good, while lower entreprise cost, improves the qualification rate of product.

Specific embodiment

With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this The protection scope of utility model is not limited by the specific implementation.

As shown in Figs. 1-2, a kind of diameter of mandrel provided by the embodiment of the utility model, intensity detecting device, including support Platform 1 and the laser diameter measuring instrument 2 being fixed in supporting table 1, the laser diameter measuring instrument 2 are raw for Beijing Rui De High Seience Technology Co., Ltd. The laser diameter measuring instrument of the model LDM501 of production, the supporting table 1 includes pedestal 13, support column 14 and erecting bed 15, described 14 upper and lower ends of support column are respectively fixedly connected with erecting bed 15 and pedestal 13；Mounting hole is set on the pedestal 13, for fixing On mill floor, the laser diameter measuring instrument 2, which is connected through a screw thread, to be fixed on erecting bed 15, and the one of the laser diameter measuring instrument 2 Side fixing intensity detection device 3, the intensity detecting device 3, which is connected through a screw thread, to be fixed on erecting bed 15, the intensity inspection The first roller bearing 5 that device 3 includes shell 4 and is fixed in shell 4 is surveyed, the two sides of the shell 4 are respectively arranged entrance hole 6 and go out String holes 7, the outer diameter height of first roller bearing 5 are lower than the height of entrance hole 6 and outlet hole 7, the entrance hole 6 and outlet hole 7 In same level height, the line at 5 center of the entrance hole 6 and outlet hole 7 and the first roller bearing forms an isosceles triangle, Since the outer diameter height of the first roller bearing 5 is lower than the height of entrance hole 6 and outlet hole 7, when plug passes through the first roller bearing 5, first Therefore the meeting of roller bearing 5 pressure certain to plug, the not high plug of intensity will disconnect, play the purpose of detection plug intensity, furthermore Laser diameter measuring instrument 2 detects the diameter of plug, so that plug meets its diametric requirements.

The fixed limiting device 8 in the other side of the laser diameter measuring instrument 2, the limiting device 8, which is connected through a screw thread, to be fixed on On erecting bed 15, the limiting device 8 includes two rollers 9 and two vertically-mounted rollers 9 being horizontally mounted, two rollers Cylinder 9 so that plug passes through, limits plug by two rollers 9 horizontally and vertically installed and moves up and down, prevent there are gap Only plug sideslip.

The second roller bearing 10, two the second roller bearings 10 and the first roller bearing 5 three is respectively set in the left and right sides of first roller bearing 5 Line between person center forms an isosceles triangle, and second roller bearing 10 is fixed on the inside of shell 4, the shell 4 Front and rear sides side wall on be arranged elongated hole 11, the both ends of second roller bearing 10 are respectively fixedly connected with screw rod 12, both ends spiral shell Bar 12 is each passed through the elongated hole 11 of two sides and the second roller bearing 10 is fixed on to the inside of shell 4 by nut 16, is set by this The height that can manually adjust the second roller bearing 10 is set, thus change the intensity of detection, higher, the intensity inspection of the second roller bearing 10 setting Higher grade is surveyed, to adapt to the testing requirements of unlike material, different-diameter plug.
