Description

Technical Field

[0001] This application relates to the field of metrology equipment technology, and in particular to a height-adjustable displacement gauge lifting measuring device. Background Technology

[0002] A displacement gauge is a displacement measuring device with an internal telescopic rod structure. It measures height, thickness, and displacement by extending or retracting the telescopic rod. Currently, there are two commonly used types of displacement gauges. The first type relies on a spring-driven telescopic rod. When no external force is applied, the telescopic rod is in its initial state (usually at its longest extension). When the displacement gauge needs to measure height changes, the telescopic rod must be manually raised, the object to be measured inserted under the telescopic rod, and then the rod released. Once the telescopic rod contacts the object, the height change can be measured.

[0003] Another approach is to use a cylinder to raise and lower the displacement gauge as a whole. When ready to measure, the cylinder raises the displacement gauge and places the object to be measured under the telescopic rod of the displacement gauge. Then the cylinder drives the displacement gauge to descend, so that the telescopic rod contacts the object to be measured, thereby measuring the height of the object.

[0004] Both solutions have certain drawbacks. The first solution is inconvenient to use, requiring manual lifting of the telescopic rod during measurement, which is impossible in some space-constrained areas, and this method cannot achieve automated measurement. The second solution affects the testing accuracy; the process of the cylinder driving the displacement gauge to rise and fall inherently has repeatability positioning errors, which will be added to the displacement gauge measurement error, causing the error to be amplified. Utility Model Content

[0005] To address the issues of inability to automate and detection errors mentioned in the background art, this application provides a height-adjustable displacement gauge lifting measuring device that achieves automated detection through a cylinder, while avoiding the accumulation of errors caused by the cylinder during movement.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] This application provides a height-adjustable displacement gauge lifting measuring device, comprising:

[0008] Measuring frame;

[0009] Both the cylinder and the linear module are mounted on the measuring frame, and the slider in the linear module is connected to the piston rod of the cylinder.

[0010] The first end of the lifting rod is fixedly connected to the slider in the linear module;

[0011] The lever is located on the second end of the lifting rod;

[0012] The pen-type displacement sensor is mounted on the measuring frame, and its probe can be reset by the drive of a lever.

[0013] The axis of the lifting rod is parallel to the axis of the pen-type displacement sensor.

[0014] In one possible implementation of this application, the first end of the lifting rod is connected to the slider in the linear module in a detachable fixed connection.

[0015] In one possible implementation of this application, the first end of the lifting rod extends into a blind hole on the slider;

[0016] It also includes a first fixing member provided on the slider, one end of which can extend into the blind hole and abut against the lifting rod.

[0017] In one possible implementation of this application, the first fastener has multiple mounting positions on the slider, and the multiple mounting positions are spaced apart along the axis of the blind hole.

[0018] In one possible implementation of this application, the pen-type displacement sensor is connected to the measuring frame in a detachable fixed connection.

[0019] In one possible implementation of this application, the measuring frame is provided with a through hole, and a portion of the pen-type displacement sensor is located inside the through hole;

[0020] It also includes a second fixing member installed on the measuring frame, one end of which can extend into the through hole and abut against the pen-type displacement sensor.

[0021] In one possible implementation of this application, the connection between the paddle and the lifting rod is a rigid connection;

[0022] The lever has a forked opening, and there is a gap between the probe of the pen-type displacement sensor and the inner wall of the forked opening.

[0023] The beneficial effects of this application are as follows:

[0024] The height-adjustable displacement gauge lifting measuring instrument provided in this application achieves automated detection through a cylinder. During the detection process, the cylinder drives the pen-type displacement sensor to move to complete the detection. The entire process does not require manual intervention and avoids the accumulation of errors caused by the cylinder, thereby improving the detection accuracy. Attached Figure Description

Detailed Implementation

[0030] The technical solutions in this application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a height-adjustable displacement gauge lifting measuring device. Please refer to [link / reference]. Figure 1 and Figure 2 In some examples, the height-adjustable displacement gauge lifting measuring device disclosed in this application includes a measuring frame 1, a cylinder 2, a linear module 3, a lifting rod 4, a lever 5, and a pen-type displacement sensor 6. Both the cylinder 2 and the linear module 3 are mounted on the measuring frame 1, and the slider 31 in the linear module 3 is connected to the piston rod of the cylinder 2.

[0032] The first end of the lifting rod 4 is fixedly connected to the slider 31 in the linear module 3, and the second end is connected to the lever 5. The probe of the pen displacement sensor 6 is connected to the lever 5. The pen displacement sensor 6 is also installed on the measuring frame 1.

[0033] Meanwhile, the axis of the lifting rod 4 is parallel to the axis of the pen-type displacement sensor 6.

[0034] Based on the above structure, the pen-type displacement sensor 6 can be used directly for measurement. If the probe of the pen-type displacement sensor 6 needs to be adjusted according to the specific measurement position before measurement, the cylinder 2 first drives the probe of the pen-type displacement sensor 6 to move closer to the measuring frame 1 through the lifting rod 4 and the paddle 5.

[0035] During measurement, cylinder 2 drives lever 5 to move closer to the object being measured via lifting rod 4. At the same time, the probe on pen displacement sensor 6 moves closer to the object being measured under the drive of spring inside pen displacement sensor 6, making contact with the object and achieving measurement.

[0036] After the measurement is completed, cylinder 2 is activated, driving the pen-type displacement sensor 6 to reset via lifting rod 4 and paddle 5. In this method, cylinder 2 only drives the length of pen-type displacement sensor 6 to change, and the change caused by cylinder 2 will not be superimposed on pen-type displacement sensor 6.

[0037] In addition, when the probe of the pen-type displacement sensor 6 contacts the object being measured, the contact force is controllable and basically constant, and will not be disturbed by the air pressure fluctuations of the cylinder 2.

[0038] In some examples, the first end of the lifting rod 4 is connected to the slider 31 in the linear module 3 in a detachable fixed connection.

[0039] For some possible implementations, please refer to Figure 3 The first end of the lifting rod 4 extends into the blind hole 32 on the slider 31. At the same time, a first fixing member 33 is added to the slider 31. One end of the first fixing member 33 can extend into the blind hole 32 and abut against the lifting rod 4.

[0040] The function of the first fixing component 33 is to temporarily fix the lifting rod 4.

[0041] In some possible implementations, the first fastener 33 may be a bolt.

[0042] In some possible implementations, the first fastener 33 has multiple mounting positions on the slider 31, which are spaced apart along the axis of the blind hole 32.

[0043] In some examples, the pen-type displacement sensor 6 is connected to the measuring frame 1 in a detachable fixed connection.

[0044] For some possible implementations, please refer to Figure 4 The measuring frame 1 is provided with a through hole 11, and a part of the pen-type displacement sensor 6 is located in the through hole 11. At the same time, a second fixing member 12 is added to the measuring frame 1. One end of the second fixing member 12 can extend into the through hole 11 and abut against the pen-type displacement sensor 6.

[0045] The function of the second fixing component 12 is to temporarily fix the pen-type displacement sensor 6.

[0046] In some possible implementations, the second fastener 12 can be a bolt.

[0047] In some examples, the paddle 5 and the lifting rod 4 are rigidly connected. The paddle 5 has a fork 51, and there is a gap between the probe of the pen displacement sensor 6 and the inner wall of the fork 51. The purpose of the gap is to prevent the paddle 5 from affecting the axial movement of the probe on the pen displacement sensor 6.

[0048] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
