The clearance gauge can rapidly measure the width of the clearance, has the characteristic of continuous reading, and simplifies and optimizes the clearance measuring process. The measuring system described in this embodiment includes a feeler described below.

As shown in fig. 1 and 2, the feeler according to the present embodiment includes a plurality of unit rulers 1 and a rotary shaft 3. The unit rulers 1 are respectively rotatably sleeved on the same rotating shaft 3 and are sequentially arranged along the axial direction of the rotating shaft 3. The rotating shaft 3 may be a bolt or a positioning pin. In the embodiment, the thickness of each unit ruler 1 is the same, that is, each unit ruler 1 is respectively used as the minimum thickness unit of the feeler in measurement. In this embodiment, each unit ruler 1 is provided with a mark for counting and/or accumulating thickness.

The feeler gauge of this embodiment utilizes unit chi 1 to rotate around pivot 3 when measuring, because every unit chi 1's thickness is the same, only need select the unit chi 1 of suitable quantity to insert and measure in the clearance to can obtain clearance thickness according to the ordinal number of sign or accumulative thickness on the current unit chi 1. The measuring process is simple and quick, the number of the used unit rulers 1 can be determined through the ordinal number of the unit ruler 1, the total thickness is calculated, or the accumulated thickness shown by the current unit ruler 1 is directly read out, and the gap width can be quickly measured. The feeler gauge can simplify the measuring process, improve the continuity of the measuring process and the directness of the reading, simplify the process of estimation and recalculation in the past into simple calculation or direct reading, and reduce unnecessary intermediate links.

As shown in fig. 3, the unit ruler 1 of the present embodiment is a rectangular plate body having a uniform thickness and different lengths. One end of the unit ruler 1 is a rotating end, and the other end of the unit ruler 1 is a measuring end. The unit ruler 1 is provided with a shaft hole through the position close to the rotating end, and the unit ruler 1 is rotatably sleeved on the rotating shaft 3 through the shaft hole. When a plurality of unit rulers 1 are simultaneously assembled on the rotating shaft 3 of the feeler gauge, the rotating ends of each unit ruler 1 are respectively sleeved on the rotating shaft 3 through respective shaft holes and are sequentially arranged along the axial direction of the rotating shaft 3. Preferably, the lengths of the unit rules 1 are different, and when the unit rules 1 are arranged, the unit rules 1 are sequentially arranged from short to long according to the length sequence of the unit rules 1, so that the unit rules 1 are arranged into a slope at the measuring end, and the unit rules 1 are convenient to select or sort during measurement.

In order to facilitate the measurement end of the unit ruler 1 to extend into the gap for measurement, the measurement end of the unit ruler 1 is preferably provided with a slope section, so that the measurement end of the unit ruler 1 can extend into the gap more conveniently. The size of the slope section is related to the depth of the gap, when the gap or the gap is shallow, the unit ruler 1 with the larger slope of the slope section of the measuring end can be selected, and similarly, for the gap or the gap with the deeper depth, the unit ruler 1 with the smaller slope of the slope section of the measuring end can be selected.

It will be appreciated that the measuring end of the unit rule 1 may be designed in other shapes, such as a step shape or an arc shape, as long as it is sufficient to facilitate the insertion of the unit rule 1 into the gap.

As shown in fig. 3, the markings on each unit rule 1 include a first marking 6 and/or a second marking 7. In other words, each unit rule 1 may be provided with only the first mark 6, only the second mark 7, or both the first mark 6 and the second mark 7. In order to facilitate reading, the unit ruler 1 of the present embodiment is provided with a display screen for displaying the first mark 6 and the second mark 7.

The present embodiment will explain the structure and the measurement process of the unit ruler 1 in detail by taking the case where the first mark 6 and the second mark 7 are provided at the same time as an example.

In the present embodiment, the first mark 6 shows the ordinal number of the current cell rule 1, and the second mark 7 shows the cumulative thickness of the current cell rule 1. In this embodiment, the ordinal number refers to the number of the cell rulers from the first cell ruler to the current cell ruler directly obtained according to the ordinal number. The cumulative thickness means a total thickness from the first unit rule to the current unit rule when the plurality of unit rules 1 are arranged. For example, if the number of the first mark 6 of the unit ruler 1 is 99, it means that the unit ruler 1 is the 99 th unit ruler 1; the number of the second mark 7 of the unit rule 1 is 0.99mm, which means that the cumulative thickness from the 1 st unit rule 1 to the unit rule 1 is 0.99mm, corresponding to the thickness of each unit rule 1 being 0.01 mm.

It is understood that the minimum unit thickness of the unit ruler 1 of the present embodiment may be 0.01mm, and other dimensions may be adopted as long as the thickness of each unit ruler 1 is ensured to be the same.

When the feeler gauge of the embodiment is used for measurement, the following two measurement modes can be adopted:

(1) based on the measurement of the first mark 6: the N unit rulers are selected from the M unit rulers to extend into the gap for measurement, the unit ruler pasted on the inner wall of one side of the gap is the 1 st unit ruler, the corresponding unit ruler pasted on the inner wall of the other side of the gap is the nth unit ruler, the number M1 of the first mark of the 1 st unit ruler and the number Mn of the first mark on the nth unit ruler are read respectively, and then the number N of the unit rulers is Mn-M1; according to the second mark shown by the first unit ruler, the minimum thickness unit of each unit ruler in the feeler ruler is S, and the gap thickness S is equal to N · S. The calculation process is simple, the estimation process is saved compared with the measurement process in the prior art, and the measurement result is more accurate.

(2) Based on the measurement of the second mark 7: when M unit rulers are arranged on a rotating shaft 3 of the clearance gauge, the 1 st unit ruler to the nth unit ruler can be selected from the M unit rulers to extend into the gap for measurement, the 1 st unit ruler is ensured to be attached to the inner wall of one side of the gap, the unit ruler attached to the inner wall of the other side of the gap is used as the nth unit ruler, the number of readings of a second mark on the nth unit ruler is directly read, and the number of readings is the accumulated thickness of the 1 st unit ruler to the nth unit ruler, namely the width of the gap. The method completely omits the calculation process in the measurement, the gap thickness can be measured through direct reading, the measurement process is further simplified, and the accuracy of the measurement result can be ensured. The method is realized based on the fact that the thickness of each unit ruler is the same.

Because the plurality of unit rulers 1 are mutually overlapped, in order to facilitate reading, the rest of the unit rulers which are shielded above the unit ruler to be read can be rotated to the position which does not influence the reading during reading; the reading number on the next unit ruler can be directly read out, and the thickness of the unit ruler is subtracted by subtraction to calculate the gap width.

In this embodiment, as shown in fig. 2, the feeler gauge further includes a protective case 2. The protective shell 2 comprises two oppositely arranged protective plates, and two ends of the two protective plates are respectively connected through a partition plate 4, so that a cover body is formed. A plurality of unit chi 1 is arranged in order between two protection shields, and the one end of two protection shields articulates in pivot 3, and this pivot 3 still passes two protection shields when passing a plurality of unit chi 1 to guarantee that two protective housing 2 arrange respectively in the head and the tail both sides of all unit chi 1, in order to utilize the protection shield to protect unit chi 1. Preferably, the two protective plates are of the same overall size. The distance between two protection shields has been guaranteed in the setting of baffle 4 to guarantee to keep safe activity space between protection shield and the unit chi 1, in order to make things convenient for unit chi 1 to follow the internal rotation of protective housing 2 and release.

In this embodiment, at least one end of the two protection plates is respectively provided with a mounting hole, and the rotating shaft penetrates through the mounting holes. At least one end of the rotating shaft is provided with a fixed end, an external thread is arranged on the fixed end of the rotating shaft, a nut is assembled outside the fixed end of the rotating shaft, and the rotating shaft is tightly propped against the two protection plates by the nut.

The pivot 3 of this embodiment is the bolt, and the position that lies in between two protection shields on the bolt is the optical axis, and the both ends of bolt are stretched out the part outside two protection shields respectively and are the stiff end respectively, are equipped with the external screw thread respectively outside two stiff ends. Nuts 5 are assembled on the external threads at the two ends of the bolt to lock the rotating shaft 3 on the two protection plates by the nuts 5, so that the stability of the clearance gauge structure is ensured.

It is understood that the rotating shaft 3 of the present embodiment may be provided with only one nut 5 at one end, or may be provided with nuts 5 at both ends, respectively. When the rotating shaft 3 is only provided with the nut 5 at one end, the other end of the rotating shaft 3 is provided with the limiting platform, namely, a bolt is adopted to replace a bolt to be used as the rotating shaft 3.

It can be understood that, in addition to the spindle 3 of the present embodiment using the screw or bolt to cooperate with the nut 5, the spindle 3 may also use an assembly structure of the pin shaft and the cotter pin, that is, the pin shaft is used to replace the screw or bolt, and the cotter pin is used to fix the pin shaft on the protective casing 2. The assembly structure of round pin axle and split pin is favorable to the separation and the equipment of protective housing, is convenient for increase and decrease unit chi 1 at any time according to the user demand.

It is understood that the protective case 2 of the present embodiment may be an integral structure or a detachable structure. When the protective case 2 is a detachable structure, the partition plate 4 is detachably fitted between the two protective plates by positioning pins. The structure that baffle 4 passes through locating pin location to be fixed on protective housing 2 has guaranteed the flexibility of clearance gauge, and when measuring clearance or gap are bigger, can take the protective housing 2 apart, arrange more unit chi 1 between two protection shields to reach the purpose that increases measuring range through the length of changing pivot 3.

The protective case 2 of this embodiment is provided with a bent opening which can expose a part of the unit ruler 1 so as to push out the unit ruler 1 quickly when all the unit rulers 1 are completely in the protective case 2.

Specifically, each unit ruler 1 of the present embodiment is a minimum measurement unit, and the thickness thereof is 0.01 mm. By superimposing the unit ruler 1, the width of the gap or gap can be read continuously, and compared with the prior art, the size of the gap does not need to be estimated, but the width of the gap is measured by directly inserting the feeler with the corresponding measuring range into the gap. The 1 front end of unit chi of this clearance gauge is the slope section, can directly put into the gap with 1 front end of unit chi like this in, the 1 gross thickness of unit chi of putting into just is the gap width in gap. When reading, the first unit ruler 1 contacting with the gap boundary is pushed out, and the unit ruler is rotated around the rotating shaft 3 and leaks out of the marked scale on the unit ruler 1 below the unit ruler, so that the width of the gap can be read.
