It is to be understood that the above definitions are only for the convenience of understanding the relative positional relationship of the parts in the flatness measuring device 100, and should not be construed as limiting the present utility model.

In this embodiment, the first direction, the second direction and the third direction are in a perpendicular relationship. That is, the first direction is perpendicular to the second direction and the third direction, respectively, and the second direction is perpendicular to the third direction.

As shown in fig. 1 and 2, the flatness measuring device 100 mainly includes: a guiding rule 120, a laser rangefinder 110 and a drive-group 140.

The guiding rule 120 is disposed on the surface 200 to be measured, an accommodating cavity 121 is defined in the guiding rule 120, a measuring opening is formed in the guiding rule 120 towards the surface 200 to be measured, the measuring opening is communicated with the accommodating cavity 121, and a rack 130 is disposed in the accommodating cavity 121 along a first direction, i.e. a length direction of the rack 130 is perpendicular to the first direction. The laser range finder 110 is disposed at the measuring opening, and the transmitting end 111 thereof is disposed towards the surface 200 to be measured, and the transmitting end 111 of the laser range finder 110 is used for transmitting laser to measure the distance between the guiding rule 120 and the surface 200 to be measured.

The driving set 140 includes a driving member 141 and a gear 142, the gear 142 is meshed with the rack 130, and the driving member 141 is connected between the laser rangefinder 110 and the gear 142 and is capable of driving the gear 142 to rotate, that is, rotating the gear 142 around a center line of the gear 142, so as to drive the laser rangefinder 110 to reciprocate in a first direction at the measuring opening.

As shown in fig. 4, for example, the driving member 141 may be a combination of a driving motor 1411 and an output shaft 1412, the output shaft 1412 is connected between the driving motor 1411 and the gear 142, the driving motor 1411 may drive the output shaft 1412 to rotate, so that the gear 142 is driven to rotate by the output shaft 1412, and the driving motor 1411 has two working modes of forward rotation and reverse rotation, so that the laser range finder 110 may be driven to reciprocate in the first direction.

Of course, the driving member 141 may also be a combination of a rotating motor and an output shaft 1412, and the rotating motor can be used instead of the driving motor 1411, and can also drive the gear 142 to rotate, so as to drive the laser range finder 110 to reciprocate at the measuring opening.

When the flatness measuring device 100 provided in this embodiment is used, the driving member 141 drives the gear 142 to rotate, so as to drive the laser rangefinder 110 to reciprocate along the first direction at the measuring opening, so that a plurality of groups of continuous distance values, that is, the distance between the measuring guiding rule 120 and the surface 200 to be measured, are measured by the laser rangefinder 110, and finally, the flatness result of the surface 200 to be measured can be obtained after the distance data is processed by software.

In the traditional flatness measuring method of the surface to be measured, a guiding rule is mainly used to be matched with a feeler gauge, and measurement is carried out manually, so that the defects of high labor cost, low efficiency, low measuring precision and the like exist.

However, in the flatness measuring apparatus 100 provided in this embodiment, when the flatness measuring apparatus 100 is used, the driving member 141 can drive the gear 142 to rotate, so as to drive the laser rangefinder 110 to reciprocate at the measuring opening, thereby measuring a plurality of continuous distance values by using the laser rangefinder 110, and finally obtaining the flatness result of the surface 200 to be measured after processing by software, so that no manual measurement is required, thereby reducing the labor cost, and meanwhile, the measuring efficiency and precision are also higher, and the product competitiveness of the flatness measuring apparatus 100 is improved.

It should be noted that, the laser rangefinder 110 is disposed at the measuring opening, so that the edge of the measuring opening can play a supporting role, and the gear 142 is effectively prevented from slipping off the rack 130 under the action of gravity, thereby improving the stability of the laser rangefinder 110 in the process of reciprocating at the measuring opening.

As shown in fig. 1, in one embodiment, in the first direction, both sides of the guiding rule 120 are respectively provided with a fixed support 150 and a telescopic support 160, the fixed support 150 and the telescopic support 160 are respectively supported on the surface 200 to be measured, and the telescopic support 160 can be extended or shortened in the third direction, i.e., the length of the telescopic support 160 is changeable.

In this embodiment, since the size of the fixed support 150 is fixed, and the telescopic support 160 can be extended or shortened along the third direction, it is convenient for a measurer to adjust the levelness of the guiding rule 120 through the telescopic support 160, so as to improve the measurement accuracy of the flatness measuring device 100.

Further, as shown in fig. 3, the telescopic support 160 includes a base 161 and a threaded fastener 162, the base 161 is connected with the guiding rule 120, a screw 1621 of the threaded fastener 162 is screwed with the base 161, and an end 1622 of the threaded fastener 162 is supported on the surface 200 to be measured.

Thus, when a measurer screws the threaded fastener 162, the screw portion of the threaded fastener 162 can be extended or shortened with respect to the base 161, thereby achieving the purpose of adjusting the levelness of the running rule 120.

By way of example, the threaded fastener 162 may be a bolt, screw, or the like having external threads.

In this embodiment, through the setting of the threaded fastener 162, the size of the telescopic support 160 can be finely adjusted, the adjustment accuracy of the levelness of the guiding ruler 120 is improved, the structure is simple, the operation is quick, and the operation and the use of measuring personnel are convenient.

As shown in fig. 2, further, the side of the guiding rule 120 facing away from the surface 200 to be measured is provided with a bubble level 170 for use with the telescopic support 160.

When the measurer adjusts the size of the telescopic support 160, the threaded fastener 162 is slowly rotated until the bubble in the bubble level 170 is at the centered position, and it can be determined that the guiding rule 120 is at the horizontal position.

Therefore, through the arrangement of the bubble level 170, the measuring staff can conveniently and rapidly adjust the guiding ruler 120 to the horizontal position, the time consumed in the adjustment process is reduced, and therefore the adjustment efficiency of the levelness of the guiding ruler 120 is improved.

As shown in fig. 1, still further, in the third direction, the height H of the fixed support 150 satisfies the relation: h is more than or equal to 10mm and less than or equal to 20mm.

In another embodiment, a supporting frame and a sliding rail may be disposed in the accommodating cavity 121, where the supporting frame is connected with the driving member 141 and is matched with the sliding rail through a sliding block to realize sliding connection, so that the gear 142 can be indirectly supported, and the gear 142 is limited to move along the second direction, thereby improving stability.

In one embodiment, length L of running rule 120 satisfies the relationship: l is more than or equal to 2m.

Illustratively, the length L of the running rule 120 may be set to 2m, 2.5m, 3m, 3.5m, 4m, 5m, 6m.

In this embodiment, the length L of the guiding rule 120 is at least set to 2m, so as to increase the reciprocating path of the laser rangefinder 110, so that more distance data can be measured in one reciprocating process, and more accurate flatness results can be obtained after the data is processed by software, so that the measurement accuracy is higher.
