Description
Technical field
The utility model relates to the milling train auxiliary equipment, more particularly, relates to a kind of milling train intersection Zero positioning measurement mechanism, and the measurement data of this measurement mechanism is true and reliable.
Background technology
PC milling train intersection Zero positioning is exactly to measure the top reference face of PC milling train cross head cushion block and the actual range of frame datum level, and then compare (see figure 1) with standard zero-bit distance, calculate difference, and relatively with the difference of value of feedback whether within prescribed limit, (difference be generally less than or equal 0.5mm) will not be if will demarcate the correction data according to actual difference in prescribed limit.Seeing also milling train intersection Zero positioning measurement mechanism 10 shown in Figure 1, present, special-purpose is " П " structure, comprises crossbeam 11 and support 12, and crossbeam 11 lower ends are provided with crossbeam datum level 111; Two equal supports 12 are located at both sides, crossbeam 11 lower end respectively, and are connected and fixed with crossbeam 11.During measurement, see also shown in Figure 2ly, two supports, 12 bottoms with this measurement mechanism are separately positioned on the frame datum level 1 earlier, and are close to frame datum level 1 and fixing; Adopt micrometer 2 to measure the distance of the top reference face 5 of crossbeam datum level 111 and cross head 3 cushion blocks 4 earlier then, because cross head 3 cushion blocks 4 can be swung, seldom can be in position with crossbeam datum level 111 absolute parallel, so need measure value respectively at the bilateral symmetry point of cross head 3 cushion blocks 4, (unit: mm), calculating mean value then is a (not shown) to count a1 and a2; Use fixed range L (being generally 170mm) between crossbeam datum level 111 and the support 12 bottom datum levels 121 to deduct the mean value a of actual measurement again, the result who is drawn is the actual range of cross head 3 cushion blocks 4 top reference faces 5 and frame datum level 1; At last by comparing, thereby demarcate and revise with standard zero-bit distance H.
Because whole this measurement mechanism 10 is to be welded by channel-section steel and steel plate, gross weight is about 15kg, because this measurement mechanism 10 itself is heavier, and the position of actual all datum levels is side direction, (schematic top plan view when Fig. 2 is measurement), therefore, in measuring process, measurement mechanism 10 needs two survey crews to lift always, and makes two bracing frames, 12 bottom sides to abutting against on the frame datum level 1, and is very inconvenient, survey crew often can not be held well, be easy to generate and rock, cause bracing frame 12 bottoms well not to be close on the frame datum level 1, cause the serious distortion of data a value; In addition, measuring the used micrometer 2 of a value needs the special messenger to measure, and error occurs easily, the easier data distortion that makes.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
Please in conjunction with Fig. 3, shown in Figure 4, milling train intersection Zero positioning measurement mechanism 20 of the present utility model comprises body 21 and depth gauge rule 22, body 21 is a rectangular structure, top surface to body 21 bottoms and body 21 two ends carries out fine finishining, make it to keep smooth bright and clean, the bottom is middle as location datum level 211, need to prove at this, adding man-hour, want the top surface at strict guarantee body 21 two ends and location between the datum level 211 apart from the tolerance and the depth of parallelism, the distance D (see figure 5) between the top surface that makes body 21 two ends and the location datum level 211 is accurate (it is preferable that distance D generally is designed to 20mm) very.212, two link stoppers 212 of link stopper that also are provided with two protrusions on the body bottom are symmetrical, and the distance between the link stopper 212 is corresponding with the length of milling train cross head 3 cushion blocks 4.Body 21 two ends are respectively equipped with symmetrical circular hole 213, and circular hole 213 runs through the above and below of body 21, and circular hole 213 diameters are greater than depth gauge rule 22 diameters.Two depth gauge rules 22 pass after inserting the circular hole 213 at body 21 two ends respectively, and are connected and fixed with body 21.Body 21 upper ends also are provided with handle 214, and handle 214 is the closed form closed-in construction, and handle 214 lower ends and body 21 welding are fixing, form an integral body, be convenient to survey crew and hold, but also can increase the rigidity of body 21, avoid causing influencing certainty of measurement because of long-time the use deforms.The both sides of body 21 also are respectively equipped with the leg 215 of symmetry, leg 215 has two pairs, each leg 215 bottom and body 21 bottoms maintain an equal level, leg 215 1 ends and body 21 sides are connected and fixed, and this leg 215 guarantees that these measurement mechanisms 20 can not produce because self thickness is too small and rocks when measuring.This measurement mechanism 20 also comprises clamp 23, clamp 23 is located at the both sides of depth gauge rule 22 respectively, clamp 23 two ends also are respectively equipped with screw 231, per two clamps 23 are oppositely arranged, pass screw 231 by bolt 232, and fastening nut 233 connects two clamps 23, and 221 1 sides of the support arm on the depth gauge rule 22 and body 21 are fixedly clamped between two clamps 23, as shown in Figure 3, one have eight clamps 23 and be used for being fixedly clamped of two depth gauge rules 22.In addition, body 21 and clamp 23 all are made with the aluminum alloy materials of hard, and weight is lighter, singlely just can mention.
See also shown in Figure 5, during measurement, holding handle 214 earlier is arranged on body 21 on PC milling train cross head 3 cushion blocks 4, location datum level 211 is adjacent to mutually with the top reference face 5 of cross head 3 cushion blocks 4, and cross head 3 cushion blocks 4 are located between two link stoppers 212, tighten mutually with two link stoppers 212, can guarantee that 2 of depth gauge rule 22 measurements are the center symmetry, mean value and actual value that final assurance is calculated are approaching; Again by clamp 23 depth gauge rule 22 that is fixedly clamped, respectively the vernier 222 of two depth gauge rules 22 is stretched out then, till vernier 222 pushes up on the frame datum level 1 respectively, pin the vernier 222 of depth gauge rule 22 then.Read the scale value of two depth gauge rules 22 this moment respectively, counts H1, H2, (H1, H2 promptly are respectively the measuring distance between the top reference face 5 of the top surface at body 21 two ends and cross head 3 cushion blocks 4); Calculate mean value H0 (not shown) by formula H0=(H1+H2) ÷ 2 then; And then deduct top surface and the location distance D between the datum level 211 at body 21 two ends with mean value H0, can draw the top reference face 5 of milling train cross head 3 cushion blocks 4 and the actual range of frame datum level 1, compare with standard zero-bit distance H more at last, thereby demarcate and revise.
Because the metering system of prior art is the preset parameter (distance L) that utilizes measurement mechanism to be deducted the resulting difference of measurement data and be absolute fix, so measured value is for obtaining indirectly; And being the resulting difference of preset parameter (distance D) of utilizing measurement data to deduct measurement mechanism, metering system of the present utility model is absolute fix, therefore this measured value is for directly obtaining, cumulative errors are few compared with prior art, and distance D is much smaller than distance L, make mismachining tolerance of the present utility model also little a lot, and because depth gauge rule is easy to use, need not the professional, make measurement data more accurate true.In addition, because material of the present utility model is slim and graceful, use very conveniently, labour intensity reduces greatly, has improved measuring speed more, and Measuring Time has shortened more than one times, and effect is obvious.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
