In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with accompanying drawing, the present invention is further detailed.
As illustrated in fig. 1 and 2, the width gauge that the embodiment of the present invention provides a kind of thrust to keep off, this width gauge comprises:
There is the fixation measuring block 11 of tubular structure, fixed rack 12 and clock gauge 13 on this fixation measuring block 11, slide post 14 is installed in the inner chamber of fixation measuring block 11, the slide over side walls of fixation measuring block 11 arranges movable measuring head 15, one end of slide post 14 and the gauge head of clock gauge 13 abut against, and the other end is in transmission connection by tapered slope structure and movable measuring head 15;
Be snug fit at the movable survey mass 16 on slide rail 12, this movable survey mass 16 has and to be relatively fixed measurement section along the glide direction of movable survey mass 16 and movable measuring head 15, movable survey mass 16 has the measuring position fixing at the zeroing position place of slide rail 12.
Fixation measuring block 11 has endoporus, and clock gauge 13 is plugged in this endoporus, makes the gauge head of clock gauge 13 be arranged in this endoporus; Slide rail 12 can adopt plate structure, movable survey mass 16 can be offered the hole be slidably matched with slide rail 12; The measuring surface of movable measuring head 15 can be plane; Fixation measuring portion on movable survey mass 16 can be a part for movable survey mass 16 outside surface, and this part can be plane; Relation between the displacement of movable measuring head 15 and the displacement of slide post 14 depends on the angle of mating surface between the two, and this angle can be arranged arbitrarily according to demand, as long as can realize the conversion between above-mentioned two numerical value.
In addition, when adopting above-mentioned width gauge, can according to the range of size choice criteria gauge block of thrust gear, the width of this standard gauge block is slightly less than the width of thrust gear, be positioned over by standard gauge block after between movable measuring head 15 and fixation measuring portion, can be fixed on slide rail 12 by movable survey mass 16, the position now residing for movable survey mass 16 is the zeroing position of slide rail 12, at this zeroing position place, the pointer of clock gauge 13 is positioned at zero-bit.
The course of work of above-mentioned width gauge is as follows: the zeroing position place first by standard gauge block, movable survey mass 16 being fixed on slide rail 12, and at this zeroing position place, the distance between movable measuring head 15 and fixation measuring portion is known quantity; Then be positioned between movable measuring head 15 and fixation measuring portion by the thrust gear needing to measure, now movable measuring head 15 will slide relative to fixation measuring block 11, and then promote the gauge head of clock gauge 13, and the registration of clock gauge 13 is changed; Repeatedly move thrust gear, obtained the minimum registration of clock gauge 13, when this minimum registration and the clock gauge 13 that are indicated by clock gauge 13 are in zero-bit, movable measuring head 15 is added with the distance between fixation measuring portion, namely obtains the width value that thrust to be measured keeps off.
Known by foregoing description, compared to the content introduced in background technology, the width gauge that the embodiment of the present invention provides realizes the width detection of thrust gear by simple structure, and the width detection coordinating the thrust making this width gauge be applicable to different size to keep off of movable survey mass 16 and slide rail 12, and when using clock gauge 13 to measure the width of thrust gear, because the error of clock gauge 13 is less, then can improve the precision of measuring process.Therefore, the width gauge that the embodiment of the present invention provides can reduce the width detection cost of thrust gear, and improve the width detection precision of thrust gear, this width gauge has higher versatility simultaneously.
Further, slide post 14 comprises isometrical shell of column and the conical surface shell of column of the middle shell of column be slidably matched with the inwall of fixation measuring block 11 and the two ends being individually fixed in this middle shell of column, isometrical shell of column outer cover dress elasticity return unit 17, this elastic reset part 17 acts between the inwall of fixation measuring block 11 and the circular bead surface of middle shell of column, conical surface shell of column and the effect of movable measuring head 15 phase.Setting up elastic reset part 17 under this structure not only can, by the distortion of elastic reset part 17, make the motion of slide post 14 more stable, can also the reset of realization activity measuring head 15 at the end of measuring, to ensure that measuring process can be more accurate.
For the ease of the corresponding relation between the displacement of computational activity measuring head 15 and the displacement of slide post 14, in the embodiment of the present invention, the glide direction of slide post 14 and the glide direction of movable measuring head 15 perpendicular, the conical surface of conical surface shell of column has the angle of 45 ° relative to the glide direction of slide post, the conical surface of movable measuring head 15 has the angle of 45 ° relative to the activity direction of movable measuring head 15.After so arranging, corresponding relation between the displacement of movable measuring head 15 and the displacement of slide post 14 is 1:1, namely just can obtain the width numerical value of thrust gear thus without the need to the conversion process of complexity, the width gauge that the embodiment of the present invention is provided has higher operability.
In aforementioned structure, slide post 14 can realize guiding by middle shell of column relative to the slip of the endoporus of fixation measuring block 11, but in order to realize the installation of elastic reset part 17, the length of middle shell of column is more limited, therefore the swing will slide post 14 being caused to occur among a small circle in sliding process, this swing will have a negative impact to measurement result.For this reason, the endoporus of fixation measuring block 11 can be set to shoulder hole, this endoporus comprises the second hole that the first hole of being slidably matched with middle shell of column and aperture are less than the first hole, and isometrical shell of column and the second hole are slidably matched, and the gauge head of clock gauge 13 is positioned at the second hole.When slide post 14 slides in the endoporus of fixation measuring block 11, guiding can be realized by middle shell of column and isometrical shell of column simultaneously, and then prevent slide post 14 from occurring swinging.
Further in technical scheme, aforesaid fixation measuring portion can be the fixation measuring head 18 on the surface protruding from movable survey mass 16, and this fixation measuring head 18 is removably installed on movable survey mass 16.After fixation measuring head 18 protrudes from the surface of movable survey mass 16, operating personnel can check whether thrust gear to be measured reliably acts on fixation measuring head 18, to improve the width measure precision of thrust gear more intuitively.In addition, after fixation measuring head 18 adopts dismountable fixed form, different fixation measuring heads 18 can be changed according to the thrust gear of different size, improve the versatility of width gauge with this; Meanwhile, when fixation measuring head 18 reaches lifetime limitation, only change fixation measuring head 18, make the maintenance cost of width gauge lower.
Measuring surface on fixation measuring head 18 can be cambered surface, but according to the design feature of thrust gear, this measuring surface is set to measurement plane by the embodiment of the present invention, this measurement plane is relative with movable measuring head 15 along the glide direction of movable survey mass 16, to increase the active area of thrust gear and fixation measuring head 18, improve measuring accuracy.
Understandably, when the measuring surface on movable measuring head 15 is plane, because movable measuring head 15 may be moved relative to thrust to be measured gear, after Long-Time Service, easily there are wearing and tearing in movable measuring head 15, causes measuring accuracy lower.In order to alleviate this problem, the measuring surface on movable measuring head 15 can be set to spherical measuring surface, this spherical measuring surface is relative with fixation measuring portion along the glide direction of movable survey mass 16.This kind of structure can reduce movable measuring head 15 and thrust keep off between contact area, and then wearing and tearing produced during relative motion both alleviating, the width gauge that the embodiment of the present invention is provided has more outstanding accuracy of detection.
When above-mentioned slide rail 12 is set to single, movable survey mass 16 easily occurs swinging relative to slide rail 12, in order to reduce this swing, in one embodiment, slide rail 12 can comprise the first slide rail 121 and the second slide rail 122, first slide rail 121 and the second slide rail 122 are parallel to each other, and movable survey mass 16 have the first through hole coordinated with the first slide rail 121 and the second through hole coordinated with the second slide rail 122.Obviously, when the slip of employing first slide rail 121 and the second slide rail 122 realization activity survey mass 16, movable survey mass 16 can be limited better relative to the position of slide rail 12, reduces the swing of movable survey mass 16 with this.
In specific embodiment, slide rail 12 can be fixed on any position of fixation measuring block 11, but during in order to reduce installation code gauge block and thrust to be measured gear, the probability that standard gauge block and thrust gear to be measured and slide rail 12 interfere, can be fixed on the one end away from movable measuring head 15 on fixation measuring block 11 by slide rail 12.So can increase the distance between slide rail 12 and movable measuring head 15, thus realize aforementioned object.
Preferably, clock gauge 13 fixes with fixation measuring block 11 by the first trip bolt 19, with the installation operation of the structure and clock gauge 13 that simplify whole width gauge, particularly, first trip bolt 19 can act on the sounding rod of clock gauge 13, and its active position should not hinder the normal work of clock gauge 13.In like manner, movable survey mass 16 is also fixedly connected with slide rail 12 by the second trip bolt 20.
Mode above only by illustrating describes some one exemplary embodiment of the present invention, undoubtedly, for those of ordinary skill in the art, when without departing from the spirit and scope of the present invention, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the claims in the present invention protection domain.
