Embodiment
As shown in Fig. 1 a and Fig. 1 b, Workpiece size detecting device of the present utility model comprises support 1 and detects piece 7, one side of described support is fixed with line slideway 3 vertically, on described line slideway 3, be provided with the slide block 4 that can slide up and down along line slideway, described slide block 4 upper end connecting drive devices.Here drive unit is for detecting cylinder 2, and described detection cylinder 2 is fixed on support 1, and the piston rod of described detection cylinder is fixedly connected with slide block 4 upper ends, drives slide block 4 to move up and down along line slideway 1 like this by detecting cylinder 2.
As Fig. 1 a, shown in Fig. 1 b and Fig. 2 b, on described support 1, be fixed with stroke dog 8, on described stroke dog 8, be fixed with stroke adjustment screw 801; Described slide block 4 upper ends extend out to stroke adjustment screw top and form extension 403.When detection cylinder 2 drives slide block 4 along line slideway 1 down sliding, in the time that touching stroke adjustment screw 801, the extension 403 of slide block 4 will stop, thus so just can be by the stroke of the height control slide block 4 of change stroke adjustment screw 801.
The utility model is by detecting size that light intensity judges workpiece whether within the error range allowing, as shown in Figure 2 a and 2 b, so described slide block 4 outsides are fixed with optical fiber fixed block 12, the two ends, left and right of described optical fiber fixed block are connected with respectively relative correlation optical fiber transmitting terminal 5 and correlation optical fiber receiving end 11.As shown in Fig. 1 a, Fig. 2 a and Fig. 2 b, described correlation optical fiber transmitting terminal 5 is connected with fiber amplifier 6 by transmitting terminal connecting line 501, described correlation optical fiber receiving end 11 is connected with fiber amplifier 6 by receiving end connecting line 1101, described fiber amplifier 6 is fixed on support 1 the above slide block 4 and is provided with teat 401, on described teat 401, have the chute 402 of vertical direction, described detection piece 7 is by being installed in chute 402, then fixing with cover plate 15 at detection piece and chute outside, detect like this piece 7 and just can in chute 402, move up and down.Described detection piece 7 is arranged between correlation optical fiber transmitting terminal 5 and correlation optical fiber receiving end 11, detect piece 7 and in the part between correlation optical fiber transmitting terminal 5 and correlation optical fiber receiving end 11, be provided with projection 701, as shown in Figure 3, described protruding 701 with to detect piece 7 one-body molded, and described protruding 701 and detect the light leak seam 702 that has horizontal direction on piece 7.
As shown in Fig. 2 b and Fig. 3, U-shaped light source filter block 16 is set between described optical fiber fixed block 12 and slide block 4, optical fiber fixed block 12 is screwed on slide block 4, and U-shaped like this light source filter block 16 is just secured in a press.Two support arms 1601 of described U-shaped light source filter block 16 insert respectively light leak seam 702 and correlation optical fiber transmitting terminal 5 and correlation optical fiber receiving end 11 through optical fiber fixed block 12, on two support arms 1601 of described U-shaped light source filter block 16, all have grating 1602.If light leak seam 702 is crossing in the horizontal direction with the grating 1602 on 16 two support arms 1601 of U-shaped light source filter block like this, the light that correlation optical fiber transmitting terminal 5 sends will be received by correlation optical fiber receiving end 11 through light leak seam 702 and grating 1602, light intensity so just can be detected, otherwise cannot detect.
Principle of work of the present utility model is as follows: as shown in Fig. 4 a, detecting piece 7 can slide up and down in chute 402, carry out the height of choose reasonable detection piece 7 light leaks seams 702 according to the tolerance of workpiece size, for the ease of detecting, select the height of light leak seam 702 to equate with the height of grating 1602.When detection, first standard-sized workpiece 9 is placed in detection platform 10, start detection cylinder 2 is with movable slider 4 to move down, and correlation optical fiber transmitting terminal 5 emission of lights are received by correlation optical fiber receiving end 11 through light leak seam and grating, then show light intensity value by fiber amplifier.As shown in Figure 4 b, in the time that light leak seam 702 overlaps with grating 1602, the light intensity value maximum that fiber amplifier detects, at this moment adjusts stroke adjustment screw 801, and it is contacted with slide block 4 extensions 403, has so just determined the position of Workpiece standard size.Then, start detection cylinder 2 upwards, takes out standard workpiece, puts into the workpiece of the error upper limit, then drives detection cylinder 2 and slide block 4 downwards until arrive the position of standard component; Because the thickness of workpiece of the error upper limit is greater than the thickness of standard workpiece, as shown in Fig. 4 d, the position consistency when position of light source fixed block 16 and examination criteria part, detecting piece 7 can move up, light leak seam 702 diminishes with the common factor of grating 1602 like this, the light intensity seeing through also diminishes, and shows the light intensity value of the upper limit by fiber amplifier.In like manner, as shown in Fig. 4 c, detect piece 7 and move down, detect the light intensity value that error lower limit workpiece sees through.When whether the size that detects workpiece is within error range, only need judge whether the light intensity value that fiber amplifier detects exceeds the scope of upper limit light intensity value and lower limit light intensity value, if exceeded, illustrate that workpiece size is not within the scope of error permission; If do not exceeded, illustrate that workpiece size is qualified.
Further, for fear of arriving correct position because greasy dirt or other impurity make to detect piece 7, as shown in Figure 2 b, described detection piece 7 tops have groove 703, in described groove 703, be placed with back-moving spring, the other end of described back-moving spring embeds in spring upper cover plate 14, and described spring upper cover plate 14 is fixed on slide block 4.
Certainly, light leak seam 702 also can be selected the height different from grating 1602, so only need to determine that light leak is sewn on the position of grating centre by error upper limit workpiece and error lower limit workpiece, then determines this normal place with stroke adjustment screw.
Although more than described embodiment of the present utility model; but those skilled in the art are to be understood that; these only illustrate; can make various changes or modifications to present embodiment; and not deviating from principle of the present utility model and essence, protection domain of the present utility model is only limited by appended claims
