Detailed Description
To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.
As used in this application and the appended claims, the terms "a," "an," "the," and/or "the" are not intended to be inclusive in the singular, but rather are intended to be inclusive in the plural, unless the context clearly dictates otherwise.
In some embodiments, as shown in fig. 4 and fig. 5, the utility model provides a portable measuring tool for time frequency terminal is used for detecting the size of the chassis of the time frequency terminal. The portable measuring tool of the time-frequency terminal comprises a length and width measuring module 2, and can be used for measuring the length, the width and the height of a time-frequency terminal case. The length and width measuring module 2 includes a length and width substrate 2A, a length and width measuring block 2D, a second fixing plate 2E, and a second set screw 2F.
As shown in fig. 6, the two opposite sides of the long and wide substrate 2A are respectively provided with a fixing plate insertion hole 2A1 and a stroke slot 2A2, which are corresponding to each other in position. The stroke grooves 2A2 correspond to the fixing plate plug holes 2A1 one by one, and the length direction of the stroke grooves 2A2 points to the fixing plate plug holes 2A 1; the adjacent side of the stroke groove 2A2 is also provided with a second plug hole 2A 3.
As shown in fig. 4 and 5, the second fixing plate 2E is inserted into the fixing plate insertion hole 2a 1. The length and width measuring block 2D is accommodated in the stroke groove 2a 2. The second fixing plates 2E and the length and width measuring blocks 2D are in one-to-one correspondence and are arranged in pairs to form a length and width measuring group O; i.e. the pitch size of the length and width measurement group O is adjusted.
As shown in fig. 4 and 5, the second set screw 2F is screwed into the second insertion hole 2a 3. When the second set screw 2F is screwed into the long and wide substrate 2A, the end of the second set screw 2F can push the long and wide measuring block 2D tightly, and further the long and wide measuring block 2D and the stroke groove 2A2 are extruded and stressed mutually, so that the long and wide measuring block 2D keeps fixed in position; when the second set screw 2F is unscrewed, the length and width measuring block 2D can perform a reciprocating linear motion in the stroke groove 2a2, thereby adjusting the distance from the corresponding second fixing plate 2E.
The design is to measure the length, width and height of the time-frequency terminal case, the length, width and height of the time-frequency terminal case are all allowed maximum values and minimum values, and the size can be considered to be qualified as long as the actual size is between the maximum value and the minimum value. The length and width substrate 2A is provided with a plurality of length and width measurement groups O, for example, two groups are provided, when the length and the size of the chassis are measured, one of the length and width measurement groups O is adjusted to the maximum value allowed by the length of the chassis, namely, the length of the length go gauge, the other one of the length and width measurement groups O is adjusted to the minimum value allowed by the length of the chassis, namely, the length of the length no-go gauge, and then the corresponding second set screw 2F is screwed into the length and width substrate 2A, so that the length and width measurement block 2D is kept fixed in position. At this time, the length edge of the case slides into the adjusted length and width measurement group O, i.e., slides into the space between the corresponding second fixing plate 2E and the length and width measurement block 2D, and when the length edge of the case can enter the length and width measurement group O with the length passing gauge size and is blocked by the length and width measurement group O with the length non-passing gauge size, the length and width of the case is immediately judged to be qualified. If the method is adopted, the length and width measurement group O is respectively adjusted to the width go gauge size and the width no-go gauge size, and then the measurement can be used for measuring the width size of the chassis. Therefore, the characteristics of the go gauge and the no-go gauge are utilized, during measurement, only whether the actual measurement size falls into the allowable range is judged, and the measurement is qualified only by comparing the actual measurement size with the allowable range without using measuring tools such as vernier calipers and the like, so that the measurement is more convenient and faster, and of course, the length and width measurement module 2 can also judge the height and the size of the case, and if the measurement is legal, the length and width measurement group O is respectively adjusted to the height and the size of the go gauge and the height and the no-go gauge.
In some embodiments, as shown in fig. 4 to 6, 6 fixing plate insertion holes 2A1 and 6 stroke slots 2A2 are respectively formed along the length direction of the long and wide substrate 2A. The number of the second fixing plates 2E and the number of the length and width measuring blocks 2D are 6; the second fixing plate 2E and the length and width measuring blocks 2D are arranged in pairs to form 6 length and width measuring groups O. When the length size of the case is measured, the adjacent three length and width measurement groups O positioned at the lower half part of the length and width substrate 2A are adjusted to the length of the go gauge, and the other three length and width measurement groups O are adjusted to the length of the no-go gauge, so that a go gauge measurement channel and a no-go gauge measurement channel along the length direction of the length and width substrate 2A are formed, and compared with single-point detection of a single length and width measurement group O, the multipoint detection result in the measurement channel is more accurate. The width dimension and the height dimension of the case are measured as if the processing is carried out.
In some embodiments, as shown in fig. 6, the travel slot 2A2 is "T" shaped in cross section, with a large slot and a small slot, and with a small notch located on the top surface of the long and wide base plate 2A. As shown in fig. 7, the length and width measuring block 2D includes a movable bottom plate 2D1 and a length and width measuring plate 2D 2. The length and width measuring plate 2D2 is arranged in the middle of the end face of the movable bottom plate 2D1, and the area of the end face of the movable bottom plate 2D1 is larger than that of the end face of the length and width measuring plate 2D 2. As shown in fig. 4 and 5, the movable floor 2D1 is received in the large slot of the travel slot 2a 2; the length and width measuring plate 2D2 extends toward the small opening of the stroke groove 2a 2. The second inserting hole 2A3 is arranged at the side of the small slot of the stroke slot 2A2 and points to the movable bottom plate 2D 1. The second set screw 2F presses the movable floor 2D1 against the bottom surface of the stroke groove 2A2 and fixes the movable floor by screwing into the long and wide base plate 2A. The top-down fixing mode is more convenient to operate. More preferably, the second inserting holes 2A3 are disposed on two sides of the stroke slot 2a2, and the two sides are fixed better.
Meanwhile, it should be noted that the stroke groove 2a2 is marked with scale marks on one side, so that the length and width measuring group O can be adjusted to the required length, width or height of the go gauge or no-go gauge more accurately. And a standard gauge, such as a standard gauge with a length of 70mm, is equipped, the scale value aligned by the length and width measurement block 2D is corrected before each measurement, and the calibration is carried out before measurement.
Further, it is considered to facilitate the "T" shape machining of the stroke groove 2a2, and to put it into use. As shown in fig. 4 and 5, the length and width measurement module 2 further includes a bottom cover plate 2B. The stroke groove 2A2 is arranged vertically through, so that the long and wide substrate 2A is provided with a large notch positioned on the bottom surface; the fixing plate insertion holes 2A1 are also provided to penetrate vertically, so that the long and wide substrate 2A has insertion hole openings on the bottom surface. The bottom sealing plate 2B is stacked and fixed at the lower end of the long and wide substrate 2A by welding, and plugs the large notch and the plugging hole, and the top surface of the bottom sealing plate 2B forms the bottom surface of the stroke groove 2A 2. Meanwhile, the length and width measuring module 2 further includes a side seal 2C. The stroke groove 2A2 penetrates to the side far from the fixing plate insertion hole 2A1 and forms a through groove opening at the side of the long and wide substrate 2A. The side seal 2C is disposed on the side of the long and wide substrate 2A, and seals the through slot.
In some embodiments, although the length and width measuring module 2 can measure the length, width and height dimensions of the chassis, this can be performed only by repeatedly turning and adjusting the position of the chassis in an actual process, which is not troublesome, in order to make the measurement work more convenient. As shown in fig. 1 to 3, the height measuring module 1 is further included. The height measurement module 1 includes a height measurement plate 1A, a height gauge 1B, a first set screw 1C, and a height base plate 1D. One end of the height gauge 1B is fixedly inserted into the height base plate 1D, and the other end is movably inserted into the height measuring plate 1A. The first set screw 1C is screwed to the rear side of the height measuring plate 1A and is directed to the height gauge 1B. The first jacking screw 1C presses the joint surfaces of the height measuring plate 1A and the height gauge 1B against each other by screwing into the height measuring plate 1A and jacking the height gauge 1B, and keeps the height measuring plate 1A and the height gauge 1B relatively fixed. The first set screw 1C changes the distance from the height base plate 1D by screwing out the height measuring plate 1A and freely moving the height measuring plate 1A in the length direction of the height gauge 1B.
The height measurement module 1 is special for measuring the height and size of the case, and when the height measurement module is used, the case is placed on the height substrate 1D, then the position of the height measurement plate 1A is adjusted to be attached to the top surface of the case, scale marks are marked on the height ruler 1B, the display value of the height ruler 1B at the position of the height measurement plate 1A is read, and the height value of the case is obtained. The height measuring module 1 is matched with the length and width measuring module 2 to respectively measure the height of the case and the length and width of the case, and the height measuring module is of a modular structure and is used for partition measurement, so that the measurement is easier to operate.
The more preferable height gauges 1B are two in total, and are each provided with a height measuring plate 1A. Thus, in actual measurement, the height measurement group P is formed between the height measurement plate 1A and the height substrate 1D. One height measurement group P can be adjusted to the maximum value allowed by the height of the case, the other height measurement group P can be adjusted to the minimum value allowed by the height of the case, namely the size of a go gauge and the size of a no-go gauge of the height of the case, and then the first jacking screw 1C is screwed in to fix the position of the height measurement plate 1A. When the height edge of the case can enter the height measurement group P with the height of the height go gauge and is blocked by the height measurement group P with the height of the height no-go gauge, the dimension is judged to be qualified immediately, and the measurement is faster by using the measurement characteristic of the go-no-go gauge.
