The watch base according to some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following embodiments, features of the embodiments may be combined with each other without conflict.

Referring to fig. 1, an embodiment of the present invention provides a measuring apparatus 100. The measuring device 100 includes a platform 10, a fixing member 20, a gauge stand 30, and a gauge 40. The fixing member 20 is disposed on the platform 10 and is used for fixing the workpiece 200 on the platform 10. The gauge stand 30 is disposed on the platform 10. The gauge 40 is provided on the gauge stand 30, and measures the workpiece 200 through the gauge stand 30.

One end of the gauge 40 is provided with an elastically stretchable measuring head 41. In this embodiment, the gauge 40 is a standard component, but is not limited thereto. The scale 40 can be a mechanical dial indicator, a digital display dial indicator and the like.

Referring to fig. 2 and 3, the gauge stand 30 includes a supporting member 31, a guiding member 33, a measuring head 35, and a first elastic member 37. The support 31 is intended to be placed on the platform 10 and to mount the gauge 40. The guide 33 is disposed on the support 31 and configured to slide from a first position to a second position relative to the support 31. The guide 33 is adapted to abut against a measuring head 41 of the gauge 40. The gauge head 35 is provided on the guide 33. The probe 35 is configured to abut against the workpiece 200. The first elastic member 37 is disposed in the supporting member 31. The first elastic element 37 is used for abutting against the guiding element 33, so that the guiding element 33 slides from the second position to the first position.

Specifically, the support 31 is provided with a support surface 311 and a mounting hole 312. The gauge 40 is carried on the support surface 311, and the measuring head 41 is configured to abut against the guide 33 through the mounting hole 312.

The elastic force of the first elastic member 37 is greater than the elastic force of the gauge 40 urging the measuring head 41 to extend outward. When the gauge 40 is carried on the support surface 311, the measurement head 41 abuts against the guide 33. The first resilient member 37 urges the guide member 33 towards the gauge 40. Further, in this embodiment, when the gauge 40 is supported on the supporting member 31, the first elastic member 37 drives the guiding member 33 to move to the first position, and when the gauge 40 is supported on the supporting member 31, the guiding member 33 does not move.

It is understood that in other embodiments, when the gauge 40 is carried on the support member 31, the first elastic member 37 may also urge the guide member 33 to move toward the gauge 40 and stop at a position between the first position and the second position.

The distance between the end of the guide 33 facing the gauge 40 and the supporting surface 311 is smaller than a predetermined value, so as to prevent the gauge 40 from being damaged by the measuring head 41 retracting beyond the allowable stroke of the gauge 40 when the guide 33 moves to the first position.

Referring to fig. 3, the guide 33 includes a guide shaft 331, a guide pin 333, and a connecting shaft 335.

The guide pin 333 is disposed in the second guide hole 314 and configured to slide relative to the support member 31. The sliding directions of the guide shaft 331 and the guide pin 333 are parallel. The connecting shaft 335 is disposed in the limiting hole 315, and is configured to move toward or away from the second position along the first position in the limiting hole 315. The connection shaft 335 is connected to the guide shaft 331 and the guide pin 333, respectively. The connecting shaft 335 moves by a distance equal to the distance between the first position and the second position. The first elastic element 37 is disposed in the second guiding hole 314. Two ends of the first elastic element 37 respectively abut against the guide pin 333 and the support element 31, so that the guide pin 333 drives the guide shaft 331 to move from the second position to the first position through the connecting shaft 335.

The connecting shaft 335 moves in synchronization with the guide shaft and the guide pin 333, and moves the guide shaft 331 between the first position and the second position.

In operation, the gauge stand 30 is placed on the platform 10, and the gauge 40 is carried on the support 31. In a natural state, the first elastic member 37 applies an elastic force to the guide pin 333 to hold the guide shaft 331 at the first position so that the gauge head 35 does not contact the workpiece 200. The support 31 is held by one hand, the pressing pin 337 is pressed, the guide pin 333 drives the guide shaft 331 to move to the second position via the connecting shaft 335, the probe portion 353 of the measuring head 35 abuts against the surface to be measured of the workpiece 200, and the measuring head 41 of the gauge 40 abuts against the guide shaft 331 and moves along with the guide shaft 331, thereby performing the measuring operation.

Referring to fig. 2, the supporting member 31 is further provided with a fastening hole 317. The button hole 317 is positioned obliquely below the button pin 337, so that two fingers of a human hand can press the button pin 337, and the other finger extends into the button hole 317, so that the supporting member 31 can be held by a single hand. It is understood that in other embodiments, the button holes 317 may be omitted. The support member 31 may also be operated with three fingers of a single hand, for example, the thumb and middle finger pressing on opposite sides of the support member 31 and the index finger pressing on the pressing pin 337.

Referring to fig. 2, the supporting member 31 is further provided with a sliding hole 316. The slide hole 316 communicates with the second guide hole 314. The guide 33 further includes a sliding pin 339. The slide pin 339 is disposed on the guide pin 333 and is capable of extending into the slide hole 316. The sliding pin 339 can slide in the sliding hole 316 and is stopped by the hole wall of the sliding hole 316, so that the sliding pin 339 moves a certain distance to limit the moving distance of the guide shaft 331. It is understood that in other embodiments, the sliding pin 339 and the sliding hole 316 may be omitted. The limiting hole 315 is used to limit the moving distance of the connecting shaft 335, so as to limit the displacement of the guide shaft 331.

Referring to fig. 1 and fig. 4, in the present embodiment, the workpiece 200 is provided with a hole 201 to be measured. The hole 201 to be measured is a stepped hole structure. The hole 201 to be tested includes a first face 2011 and a second face 2013. The first face 2011 and the second face 2013 are parallel to the axis of the hole 201 to be measured, but are not limited thereto.

The pressing member 23 includes a guide rod 231, a pressing portion 233, and a stopper 235. The guide rod 231 is disposed on the platform 10 and can slide relative to the platform 10. The pressing portion 233 is disposed at one end of the guide rod 231, and is used for pressing the workpiece 200. The stopping portion 235 is disposed at an end of the guide rod 231 away from the pressing portion 233. The second elastic member 25 is disposed on the guide rod 231. Two ends of the second elastic element 25 respectively abut against the platform 10 and the abutting portion 235, so as to drive the pressing portion 233 to abut against the workpiece 200 on the platform 10.

In this embodiment, the first elastic member 37 and the second elastic member 25 are compression springs, but are not limited thereto. For example, in other embodiments, the first elastic member 37 and the second elastic member 25 may also be elastic structures such as disc springs.

Referring to fig. 1, the fixing member 20 further includes a positioning member 27. The positioning element 27 is disposed on the platform 10 and configured to abut against different positions of the supporting element 31, so that the measuring head 35 abuts against different surfaces to be measured on the workpiece 200 respectively. The positioning member 27 includes a stopper pin 271 and a reference portion 273. The limit pins 271 are of a cylindrical structure, and the number of the limit pins is three.
