Description

Technical Field

[0001] The utility model relates to a measuring device, in particular to a measuring device for detecting the height of a part, belonging to the technical field of mechanical parts. Background Art

[0002] Parts are the basic elements of machines. When processing parts, their height often needs to be measured to ensure the accuracy of the parts after processing to meet production requirements. Usually, calipers or digital height gauges are used to measure the height of parts.

[0003] A Chinese patent publication (publication number: CN218724028U) discloses a height measuring device for hardware parts processing, including a mechanism housing, a base is fixedly connected to the front bottom of the mechanism housing, and a height measuring mechanism is also provided at the front end of the mechanism housing and above the base. The height measuring mechanism is arranged such that after the hardware parts to be measured are placed on the top surface of the mechanism housing, a driving motor is started to rotate the screw rod and then drive the connecting block to move downward, so that the altimeter automatically moves downward until its sensing end contacts the top surface of the hardware parts to be measured. Finally, the height of the hardware parts can be obtained by reading the value displayed on the altimeter, so as to achieve the purpose of quickly measuring the height of the hardware parts when processing the hardware parts. Compared with the traditional altimeter, there is no need to frequently adjust the height of the altimeter, and the operation is simple and convenient, thereby improving the measurement efficiency of the hardware parts by the measurement personnel when processing the hardware parts.

[0004] Although the height of the altimeter does not need to be adjusted frequently when the device is used, the driving motor rotates too fast, which can easily cause the measuring head on the altimeter to collide with the top of the part to be measured when the altimeter moves downward, damaging the measuring head and making the measured value inaccurate. Therefore, a measuring device for detecting the height of parts is proposed. Utility Model Content

[0022] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0023] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, the embodiment of the utility model provides a measuring device for detecting the height of a part, comprising a base 1, a shell 2 is fixedly mounted on the top of the base 1, and an adjustment component 4 is arranged in the shell 2;

[0025] The adjusting component 4 includes a coarse threaded rod 401, a coarse threaded hole 402, a fine threaded rod 403, a fine threaded hole 404, a U-shaped limit frame 405, a square groove 406, a limit plate 407 and a circular hole 408. A coarse threaded hole 402 is provided on the top inner wall of the shell 2, and the coarse threaded rod 401 is connected to the inner thread of the coarse threaded hole 402. A square groove 406 is provided at the bottom of the coarse threaded rod 401, and a U-shaped limit frame 405 is arranged in the square groove 406. The bottom of the U-shaped limit frame 405 is rotatably installed with the top of the movable plate 3 through a bearing, a circular hole 408 connected to the square groove 406 is opened in the coarse threaded rod 401, a fine threaded hole 404 is opened on the inner wall of the top of the U-shaped limit frame 405, and the fine threaded hole 404 is threadedly connected to the fine threaded rod 403, the outer side of the fine threaded rod 403 is in movably contact with the inner wall of the circular hole 408, and a limit plate 407 is fixedly sleeved on the outer side of the bottom end of the fine threaded rod 403.

[0026] In one embodiment, a square hole 201 is provided on the inner wall on the left side of the shell 2, and a guide rod 202 is fixedly installed between the top inner wall and the bottom inner wall of the square hole 201. A movable plate 3 is slidably sleeved on the guide rod 202. The left side of the movable plate 3 extends to the outside of the shell 2 and is fixedly installed with a digital altimeter 5. A guide hole is provided on the movable plate 3, which is in sliding contact with the outer wall of the guide rod 202. The position adjustment of the digital altimeter 5 is achieved by cooperating with the guide hole and the guide rod 202.

[0027] In one embodiment, the top end of the coarse threaded rod 401 extends to the top of the shell 2 and is fixedly installed with a first rotating handle, and the top end of the fine threaded rod 403 extends to the top of the coarse threaded rod 401 and is fixedly installed with a second rotating handle. The coarse threaded rod 401 and the fine threaded rod 403 are adjusted by the first rotating handle and the second rotating handle respectively.

[0028] In one embodiment, the outer side of the U-shaped limiting frame 405 is in active contact with the inner side wall of the square groove 406 , and the U-shaped limiting frame 405 allows the coarse threaded rod 401 to rotate while driving the fine threaded rod 403 to rotate.

[0029] In one embodiment, the bottom end of the coarse threaded rod 401 is in active contact with the top of the movable plate 3 , so that the height of the digital altimeter 5 can be finely adjusted by rotating the fine threaded rod 403 alone.

[0030] When the utility model is in operation: a part to be measured in height is placed on the upper surface of the base 1 and directly below the digital display altimeter 5, the first rotating handle is rotated to drive the coarse threaded rod 401 to rotate, the coarse threaded rod 401 is threadedly matched with the coarse threaded hole 402, the coarse threaded rod 401 drives the fine threaded rod 403 to move downward, the fine threaded rod 403 drives the U-shaped limit frame 405 to move downward, the U-shaped limit frame 405 pushes the moving plate 3 to move downward quickly, the moving plate 3 drives the digital display altimeter 5 to move downward quickly, so that the measuring head is close to the upper surface of the part, when there is still a gap between the measuring head and the upper surface of the part, the first rotating handle is stopped at this time, The second rotating handle is turned to drive the fine threaded rod 403 to rotate. The fine threaded rod 403 and the fine threaded hole 404 are threadedly matched, so that the U-shaped limit frame 405 moves downward. The U-shaped limit frame 405 pushes the movable plate 3 to move slowly downward. The movable plate 3 drives the digital altimeter 5 to move slowly downward, so that the measuring head contacts the upper surface of the part. The height of the digital altimeter 5 is fine-tuned through the fine threaded rod 403, the fine threaded hole 404 and the U-shaped limit frame 405, which effectively avoids the phenomenon that the digital altimeter 5 moves downward quickly and causes the measuring head to collide with the upper surface of the part and cause damage to the measuring head, thereby extending the service life of the digital altimeter 5 and the accuracy during measurement.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
