Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 and 2, an embodiment of the invention provides a measuring apparatus 100 for measuring a dimension of a workpiece 200. The measuring device 100 includes a base 10, a positioning mechanism 20, and a measuring mechanism 30. The positioning mechanism 20 is disposed on the base 10 for positioning the workpiece 200. The measuring mechanism 30 is disposed on the base 10 for measuring the size of the workpiece 200.

In the illustrated embodiment, the workpiece 200 includes a first plate 201 and a second plate 202. The second plate 202 is vertically disposed on the first plate 201. The first plate 201 includes a first end surface 2012 and a second end surface 2014 disposed oppositely. The second plate 202 includes a third end surface 2021 facing the first end surface 2012. The measuring mechanism 30 is used for measuring the length of the first board 201 (i.e., the distance between the first end face 2012 and the second end face 2014) and the position of the second board 202 on the first board 201 (i.e., the distance between the third end face 2021 and the first end face 2012).

The base 10 includes a fixing plate 11 and four supporting rods 13 disposed on the fixing plate 11.

The positioning mechanism 20 includes a positioning block 22 and a positioning rod 24. The positioning block 22 is disposed on the fixing plate 11. The positioning block 22 is used for abutting against the first end surface 2012 to make it in a reference position. The positioning rod 24 is disposed on the fixing plate 11, and is used for abutting against a side surface of the workpiece 200 perpendicular to the first end surface 2012 to position the workpiece 200 in another direction.

It will be appreciated that in other embodiments, the positioning mechanism 20 may be of other configurations, such as providing a contoured cavity or the like to hold the workpiece 200.

Referring to fig. 3 and fig. 4, a positioning hole 110 is formed on the base 10. The first measuring module 32 includes a fixing bar 329. The fixing rod 329 is adapted to the positioning hole 110. The fixing rod 329 is inserted into the positioning hole 110 to position the first measuring part 323.

The measuring mechanism 30 includes a first slide rail 321 and a first measuring part 323. The first measuring member 323 is slidably disposed on the first sliding rail 321.

The first measuring part 323 is used for measuring the position of the second board 202 on the first board 201 by calculating the position of the third end surface 2021. Specifically, a preset standard length of the distance between the third end surface 2021 and the first end surface 2012 is defined as a, and the value obtained by the first measuring part 323 is 0 at this time; when the distance between the first measuring element 323 and the third end 2021 of a workpiece 200 is b, the positions of the second plate 202 of the workpiece 200 on the first plate 201 are a-b.

In the illustrated embodiment, the number of the positioning holes 110 is two, and it can be understood that the number and the positions of the positioning holes 110 can be set according to the position where the first measuring part 323 needs to be stopped.

In the illustrated embodiment, the pilot hole 110 includes a first slope 1101. The fixing bar 329 includes a second inclined surface 3291. After the fixing rod 329 extends into the positioning hole 110, the first inclined surface 1101 abuts against the second inclined surface 3291 to adjust the position of the fixing rod 329 and accurately position the first measuring part 323.

In the illustrated embodiment, the fixing rod 329 is further sleeved with an elastic member 3293. The elastic member 3293 drives the fixing rod 329 to move towards the positioning hole 110, so as to ensure the positioning accuracy of the first inclined surface 1101 and the second inclined surface 3291.

In the illustrated embodiment, the securing lever 329 is further provided with a handle 3295. The handle 3295 is located at an end of the fixing rod 329 far away from the positioning hole 110. After the handle 3295 is rotated, the fixing rod 329 is lifted up, so that the fixing rod 329 is far away from the positioning hole 110, and the first measuring part 323 can move.

In the illustrated embodiment, the first measuring module 32 includes a first slide rail 321, a first measuring member 323, and a mounting plate 325. The first slide rail 321 is disposed on the fixing plate 11. The first slide rail 321 is disposed along a direction perpendicular to the positioning block 22. The mounting plate 325 is slidably disposed on the first slide rail 321, and the first measuring member 323 is disposed on the mounting plate 325. The fixing rod 329 is slidably inserted through the mounting plate 325.

In the illustrated embodiment, the first measuring member 323 is slidably disposed on the mounting plate 325 to measure the dimensions of different portions of the third end surface 2021.

In the illustrated embodiment, the first measurement module 32 further includes a stop bar 327. The stopping rod 327 is disposed on the fixing plate 11 for stopping the mounting plate 325 to limit the moving position thereof.

In the illustrated embodiment, the measurement mechanism 30 further includes a second measurement module 34. The second measuring module 34 is located on a side away from the positioning block 22. The second measuring module 34 is configured to measure a distance between the second measuring module and the second end face 2014 to obtain a length of the first plate 201 through conversion.

The second measuring module 34 includes a second slide rail 341 and a second measuring member 343. The second sliding rail 341 is disposed on the base 10. The second measuring member 343 is slidably disposed on the second sliding rail 341.

In the illustrated embodiment, the first measuring part 323 and the second measuring part 343 are dial indicators, but are not limited thereto.

In the illustrated embodiment, the measurement mechanism 30 also includes a zeroing block 36. The shape of the zeroing block 36 approximates the shape of the workpiece 200. The zeroing block 36 includes a positioning surface 361, a first zeroing surface 363, and a second zeroing surface 365. After the positioning surface 361 abuts against the positioning block 22, the position of the first zeroing surface 363 is a standard position preset on the second end surface 2014, and the position of the second zeroing surface 365 is a standard position preset on the third end surface 2021. The first measuring part 323 and the second measuring part 343 are adjusted so that the measuring ends thereof are corrected and zeroed after abutting against the first zeroing plane 363 or the second zeroing plane 365.

It is understood that in other embodiments, the zeroing block 36 may be omitted.

When the measuring device 100 is in use: the first 323 and second 343 measuring elements are calibrated and zeroed by the zeroing block 36. Then, the workpiece 200 is placed on the base 10, and the first end surface 2012 is attached to the positioning block 22. After the mounting plate 325 is moved to the measurement position, the fixing rod 329 is released by rotating the handle 3295 so as to extend into the positioning hole 110 for positioning. Thereafter, the first measuring member 323 is moved to perform measurement. After that, the second measuring part 343 is moved to perform the measurement.

The measuring device 100 is located by the locating hole 110 on the base 10 and the fixing rod 329 of the first measuring module 32, so that the first measuring module 32 is located at a more precise position, and the measuring result is accurate.
