The clearance measuring device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 1 and 2, a gap measuring apparatus according to some embodiments of the present application includes: a first scale 100, a second scale 200, a third scale 300 and a fourth scale 400; the second scale 200 is slidably connected to the first scale 100 along a first direction X, and the third scale 300 is slidably connected to the second scale 200, wherein the first direction X is an extending direction of the first scale 100 and the second scale 200; along the second direction Y, the first scale 100 is provided with a first measuring part 110, the second scale 200 is provided with a second measuring part 210, the third scale 300 is provided with a third measuring part 310, and a preset included angle A0 is formed between the second direction Y and the first direction X; the fourth scale 400 is connected to the third measuring part 310 and extends from the third measuring part 310 to the second measuring part 210 along a direction perpendicular to the second direction Y; the first scale 100 is provided with first graduation marks 101 distributed along the extending direction, the second scale 200 is provided with second graduation marks 201 distributed along the extending direction, and the fourth scale 400 is provided with third graduation marks 401 distributed along the extending direction.

In the embodiment of the present application, when the gap 600 between two planes is measured using the gap measuring device, the first measuring part 110 and the second measuring part 210 are simultaneously inserted into the gap 600 to be measured, the first measuring part 110 is attached to the first plane 610 forming the gap 600, the second measuring part 210 is attached to the second plane 620 forming the gap 600, and the distance value L1 between the first measuring part 110 and the second measuring part 210 along the first direction X can be determined by the first scale mark 101 on the first scale 100. Further, by adjusting the movement of the third scale 300 relative to the second scale 200, the third measuring portion 310 is moved by the third scale 300, and the distance value L2 between the second measuring portion 210 and the third measuring portion 310 along the first direction X can be determined by the second graduation mark 201 on the second scale 200. When the value L2 is equal to the value L1, it can be known according to the principle of similar triangle that the vertical distance L0 between the first measuring portion 110 and the second measuring portion 210 is equal to the vertical distance L3 between the second measuring portion 210 and the third measuring portion 310. Further, the value read by the third graduation mark 401 on the fourth scale 400 is L3, that is, the measurement result of the gap size obtained by measurement. Therefore, when the gap 600 is measured by adopting the gap measuring device provided by the application, the gap 600 is not limited by the space where the gap 600 is positioned, the operation is convenient and flexible, the measurement result is convenient and visual to read, and the accuracy of the measurement result is higher.

It will be appreciated that as shown in fig. 2, the first scale 100, the second scale 200 and the third scale 300 each extend in the first direction X, and the first measuring portion 110, the second measuring portion 210 and the third measuring portion 310 each extend in the second direction Y. Wherein, the distance between the first measuring part 110 and the second measuring part 210 along the first direction X is L1, the distance between the second measuring part 210 and the third measuring part 310 along the first direction X is L2, the vertical distance between the first measuring part 110 and the second measuring part 210 is L0, and the vertical distance between the second measuring part 210 and the third measuring part 310 is L3.

According to the principle of similar triangles, l1/l2=l0/l3; when l1=l2, l0=l3 can be deduced, and thus, by reading the value on the fourth scale 400, the measured value of the gap 600 can be obtained.

When the first, second, and third graduations 101, 201, and 401 are provided, it is necessary to take the thicknesses of the first, second, and third measuring parts 110, 210, and 310 into consideration, respectively, so that the distance L1 between the first and second measuring parts 110 and 210 in the first direction X can be represented by the first graduation 101, the distance L2 between the second and third measuring parts 210 and 310 in the first direction X can be represented by the second graduation 201, and the actual measurement value of the gap 600 can be represented by the third graduation 401. The specific arrangement of the first tick mark 101, the second tick mark 201, and the third tick mark 401 can be determined by those skilled in the art according to the actual structure of the gap measurement device, which is not limited in this embodiment of the present application.

In a specific application, the first scale 100, the second scale 200 and the third scale 300 are each bar-shaped structures and each extend along the first direction X. The first measuring portion 110, the first measuring portion 110 and the third measuring portion 310 are all located on the same side of the first scale 100 and all extend along the second direction Y. The lengths of the first scale 100, the second scale 200, and the third scale 300, and the lengths of the first measuring part 110, and the third measuring part 310 may be determined according to actual measurement needs, which is not limited in the embodiment of the present application.

Specifically, the fourth scale 400 is disposed on the third measuring part 310, the extending direction of the fourth scale 400 is perpendicular to the extending direction of the third measuring part 310, and the end of the fourth scale 400 away from the third measuring part 310 intersects the second measuring part 210, so that the value on the third scale line 401 can be read based on the intersection position of the second measuring part 210 and the fourth scale 400 during the measurement.

In some embodiments, the first measuring portion 110 and the first scale 100, the second measuring portion 210 and the second scale 200, and the third measuring portion 310 and the third scale 300 may be fixedly connected or movably connected.

It should be noted that, to ensure accuracy of the measurement result, the first measurement portion 110, the second measurement portion 210, and the third measurement portion 310 are disposed parallel to each other, and specific connection manners between the first measurement portion 110 and the first scale 100, between the second measurement portion 210 and the second scale 200, and between the third measurement portion 310 and the third scale 300 may be set according to actual needs.

Optionally, as shown in fig. 1 and 4, the gap measuring device further includes: the fourth measuring part 500, the fourth measuring part 500 is disposed on one side of the third measuring part 310 near the second measuring part 210, the fourth measuring part 500 extends along the second direction Y, and a clamping space is formed between the fourth measuring part 500 and the second measuring part 210, and is used for screening the gasket 700 matched with the measured gap 600.

It will be appreciated that during machining, a matching spacer 700 is required to be selected for the gap 600, and after the gap size of the target gap 600 is measured, the thickness range of the spacer 700 required for design is converted based on the design tolerance of the spacer 700 according to the obtained measurement data, and then the thickness of the actual spacer 700 is measured to screen out the spacer 700 meeting the design requirement so as to match the target gap 600.

In the embodiment of the present application, by providing the fourth measuring part 500 in the gap measuring apparatus, the fourth measuring part 500 is provided at one side of the third measuring part 310 near the second measuring part 210, and a clamping space is formed between the fourth measuring part 500 and the second measuring part 210, the distance between the fourth measuring part 500 and the second measuring part 210 can be set to the minimum tolerance thickness of the gasket 700 matched with the measured gap 600, and further by inserting the actual gasket 700 between the third measuring part 310 and the second measuring part 210, by judging whether the inserted gasket 700 can pass through the clamping space, it is possible to directly determine whether the gasket 700 meets the minimum tolerance requirement, thus, the gasket 700 matched with the measured gap 600 can be directly screened, the operation is simple and convenient, the efficiency is high, and the human error when measuring the thickness of the gasket 700 can also be reduced.

Specifically, when the gap 600 is measured by using the gap measuring device of the present application, the distance between the second measuring part 210 and the third measuring part 310 is the gap size of the measured gap 600, and further, the fourth measuring part 500 is disposed on one side of the third measuring part 310 close to the second measuring part 210, and the distance between the fourth measuring part 500 and the second measuring part 210 is set to be equal to the minimum tolerance thickness of the spacer 700 matched with the measured gap 600. Thus, by inserting the actual gasket 700 between the second measuring portion 210 and the third measuring portion 310, it can be determined whether the gasket 700 satisfies the design requirement by determining whether the gasket 700 can smoothly enter between the second measuring portion 210 and the third measuring portion 310 and between the fourth measuring portion 500 and the second measuring portion 210.

For example, as shown in fig. 8a, 8b and 8c, the gap size measured by the gap measuring device is 10mm, and if the thickness design range of the spacer 700 matching the gap 600 is 9 to 10mm, the interval between the fourth measuring part 500 and the second measuring part 210 may be set to 9mm, and at this time, the interval between the second measuring part 210 and the third measuring part 310 is 10mm.

In the process of screening the gasket, as shown in fig. 8a, it is assumed that the thickness of the gasket 700 No. 1 is 9.8mm, and the gasket 700 No. 1 can smoothly enter between the second measuring part 210 and the third measuring part 310, but cannot enter between the fourth measuring part 500 and the second measuring part 210, so that it can be determined that the gasket 700 is screened and passed, thereby meeting the design requirement.

As shown in fig. 8b, assuming that the thickness of gasket No. 2 700 is 10.2mm, gasket No. 2 700 cannot smoothly enter between second measuring portion 210 and third measuring portion 310, and therefore, it can be determined that the gasket 700 is not screened and does not meet the design requirement.

As shown in fig. 8c, assuming that the thickness of the No. 3 spacer 700 is 8.7mm, the No. 3 spacer 700 can smoothly enter between the second measuring part 210 and the third measuring part 310 and between the fourth measuring part 500 and the second measuring part 210, and thus, it can be determined that the spacer 700 is not screened, and the design requirement is not satisfied.

In the embodiment of the present application, the clamping space formed by the second measuring part 210, the third measuring part 310 and the fourth measuring part 500 can be directly used for screening the gasket 700, and the operation is simple and convenient.

In a specific application, the fourth measuring part 500 may be movably connected to the third measuring part 310, and by adjusting the phase position of the fourth measuring part 500 on the third measuring part 310, the spacing between the fourth measuring part 500 and the second measuring part 210 may be adjusted.

It is understood that in practical applications, the upper limit of the thickness design range of spacer 700 that matches measured gap 600 may be greater than or less than the measured value of gap 600. In the spacer screening, the upper limit and the lower limit of the thickness range of spacer 700 may be determined from the measured value of gap 600, and the interval between second measuring unit 210 and third measuring unit 310 may be adjusted to be the upper limit of the thickness of spacer 700. Similarly, the interval between fourth measuring portion 500 and second measuring portion 210 is adjusted so that the interval is equal to the lower limit value of the thickness of spacer 700. Thus, by inserting actual spacer 700 between second measuring section 210 and third measuring section 310, and between fourth measuring section 500 and second measuring section 210, screening of spacer 700 can be achieved.

Of course, in screening the gasket 700 using the gap measuring device, the arrangement of the distance between the second measuring part 210 and the third measuring part 310 and the arrangement of the distance between the fourth measuring part 500 and the second measuring part 210 may be determined according to the size of the gap 600 and the design tolerance of the gasket 700 matched with the gap 600, which is not limited in the embodiment of the present application.

Optionally, as shown in fig. 4, the gap measuring device further includes: a fifth scale 510; the fifth scale 510 is movably connected to the third measuring portion 310 along a direction perpendicular to the second direction Y, one end of the fifth scale 510 away from the third measuring portion 310 is connected to the fourth measuring portion 500, and fourth scale marks 511 distributed along the extending direction of the fifth scale 510 are provided on the fifth scale 510.

In the embodiment of the present application, the fifth scale 510 is disposed between the third measuring portion 310 and the fourth measuring portion 500, and the fifth scale 510 is movably connected to the third measuring portion 310, and by adjusting the positions of the fifth scale 510 and the third measuring portion 310, the adjustment of the space between the third measuring portion 310 and the fourth measuring portion 500 can be intuitively implemented, so that the setting of the space between the fourth measuring portion 500 and the second measuring portion 210 is convenient when the gasket 700 is screened, the operation is simple and convenient, and the screening efficiency of the gasket 700 can be improved.

It is understood that the thickness range of spacer 700 is calculated by adding or subtracting tolerance values based on the measured value of gap 600. When the gap 600 is measured by the gap measuring device of the present application, the distance between the second measuring portion 210 and the third measuring portion 310 is the measured value of the gap 600. The interval between the third measuring part 310 and the fourth measuring part 500 may be set to be the lower tolerance value of the gasket 700 matched with the gap 600, and at this time, the interval between the fourth measuring part 500 and the second measuring part 210 is the lower limit value of the selected gasket 700.

Specifically, a fifth scale 510 is disposed between the third measuring part 310 and the fourth measuring part 500, the fifth scale 510 is movably connected to the third measuring part 310, and the interval between the third measuring part 310 and the fourth measuring part 500 can be adjusted by the fifth scale 510. In practical application, the value on the fifth scale 510 is adjusted to be equal to the lower tolerance value of the spacer 700, and at this time, the interval between the fourth measuring portion 500 and the second measuring portion 210 is the lower limit value of the selected spacer 700. By providing the fifth scale 510, the distance between the fourth measuring part 500 and the second measuring part 210 can be set more intuitively and conveniently, so that screening of the spacer 700 can be performed.

For example, the measured value obtained by measuring the target gap 600 by the gap measuring device is 10mm, and the lower tolerance value of the spacer 700 matched with the measured value is-1 mm, that is, the lower limit value of the thickness of the spacer 700 is 9mm. In the process of screening the spacer 700, the value displayed on the fourth scale line 511 on the fifth scale 510 may be directly adjusted to 1mm, and at this time, the distance between the fourth measuring part 500 and the second measuring part 210 is 9mm. This is accomplished by directly adjusting fifth scale 510 during operation without scaling the thickness design range of spacer 700.

When the fourth graduation mark 511 on the fifth scale 510 is provided, the influence of the thicknesses of the second measuring portion 210, the third measuring portion 310, and the fourth measuring portion 500 on the graduation value on the fifth scale 510 should be considered so that the numerical value displayed on the fourth graduation mark 511 exactly corresponds to the design tolerance value of the spacer 700. Of course, the specific arrangement of the fourth graduation marks 511 may be determined according to actual needs, which is not limited in the embodiment of the present application.

Optionally, as shown in fig. 4, the gap measuring device further includes: an adjustment mechanism 520; the adjusting mechanism 520 is disposed between the fifth scale 510 and the third measuring portion 310, and the adjusting mechanism 520 is used for adjusting the relative position between the fifth scale 510 and the third measuring portion 310.

In the embodiment of the present application, an adjusting mechanism 520 may be disposed between the fifth scale 510 and the third measuring portion 310, and the fifth scale 510 and the third measuring portion 310 may be movably connected by the adjusting mechanism 520, and the relative position between the fifth scale 510 and the third measuring portion 310 may be adjusted by the adjusting mechanism 520, so as to facilitate adjustment of the distance between the fourth measuring portion 500 and the second measuring portion 210.

In some embodiments, the adjustment mechanism 520 may be provided as a slider-slide mechanism. Specifically, the adjusting mechanism 520 may include a sliding block and a sliding groove, where a sliding block is disposed on a side of the third measuring portion 310 facing the fifth scale 510, and correspondingly, a sliding groove is disposed on the fifth scale 510, and an extending direction of the sliding groove is consistent with an extending direction of the fifth scale 510, and the sliding block is clamped in the sliding groove.

In a specific application, the relative position of the fifth scale 510 and the third measuring portion 310 can be adjusted by moving the slide block in the slide groove, so that the distance between the fourth measuring portion 500 and the third measuring portion 310 can be adjusted, and the slide block slide groove mechanism is adopted to realize adjustable connection between the fifth scale 510 and the third measuring portion 310, so that the structure is simple, and the operation is easy.

In some embodiments, the adjustment mechanism 520 may be provided as a rack and pinion mechanism. Specifically, the adjusting mechanism 520 may include a gear rotatably coupled to the third measuring part 310 and a rack fixedly coupled to the fifth scale 510, the gear and the rack being engaged with each other.
