Description
Technical Field

[0002] In modern industry and scientific research, various types of probes are widely used in detection, measurement and analysis. There are many types of probes with different sizes, and the demand for clamping devices has also increased accordingly. However, traditional clamping devices usually have many shortcomings, especially in adapting to probes of multiple sizes and adjusting pressure displays. At present, most clamping devices lack pressure display function. Users cannot intuitively understand the size of the clamping force during operation. They can only rely on experience and feel to adjust, which makes it difficult to ensure that the probe is clamped safely and stably. If the clamping force is too large, the probe may be damaged; if the clamping force is too small, it is easy to cause the probe to loosen, affecting the measurement accuracy. In addition, due to the variety of probe sizes, traditional clamping devices are difficult to be compatible with multiple sizes. Some devices need to be equipped with multiple clamps, which increases the cost of use and reduces work efficiency. Utility Model Content

DETAILED DESCRIPTION
[0020] See also Figures 1 to 4 The pressure-display magnetic clamping device of this embodiment, which is suitable for probes of multiple sizes, includes a base. The base includes two parts, an upper part and an lower part, which are convenient for actual production and processing. The upper part of the base 301 is disc-shaped and contains four through-holes. The lower part of the base 302 is cylindrical. The two parts are fixedly connected by screws through the four through-holes of the disc-shaped base 301. There is a circular hole in the middle of the upper and lower parts.
[0021] The lower cylindrical base 302 is provided with a fixing groove, a strong rubidium magnet is embedded in the bottom, and long holes are opened radially every 90° on all sides. The groove body is provided with a probe fixing boss 900, a pressure sensor 801, a sensor fixing boss 700, a spring 500, a spring limit ring 400, a fixing rod 101 and a pressure rod 102 from bottom to top, and there is also a fixing nut 200 on the upper part of the base.
[0022] The pressure rod 102 is hollow and has the same inner diameter as the fixed rod 101. The fixed rod 101 is nested inside the pressure rod 102, and the bottom extends to the outside of the pressure rod 102. In actual use, the pressure rod can move up and down along the fixed rod.
[0023] The spring retaining ring 400 has a side opening. After being nested in the bottom of the pressure rod 102, it can be fixed to the bottom of the pressure rod by tightening a screw in the side opening. The spring 500 is nested in the fixing rod. In actual use, the spring retaining ring and the sensor fixing boss serve as the upper and lower contact surfaces of the spring, respectively.
[0024] The central body of the sensor-fixing boss 700 is circular, with outward extensions every 90° to prevent the pressure rod from swaying during use and ensure that applied pressure acts perpendicularly on the probe. Two threaded holes extend through the center for securing the pressure sensor 801. The upper surface of the sensor-fixing boss 700 has a cylindrical groove with threads, and the lower surface has a groove with the same diameter as the pressure sensor. After the fixing rod 101 is nested within the pressure rod 102, its bottom end is threadedly connected to the cylindrical groove in the upper center surface of the sensor-fixing boss 700.
[0025] The pressure sensor 801 has two through-holes for threaded connection with other components. The pressure sensor interface 802 is connected to an external pressure display device via a connecting line to display the current pressure in real time.
[0026] The upper surface of the probe fixing boss 900 contains two through-holes, which are threadedly connected to the pressure sensor 801 through the through-holes. The bottom of the boss has grooves of different diameters, arranged from small to large, with the small diameter on the top and the large diameter on the bottom, so as to be compatible with probes of various diameters.
[0027] During use, after the two parts of the base are fixedly connected by screws, the fixing nut 200 is screwed along the thread of the pressure rod 102 to the top position of the pressure rod 102, and then the pressure rod 102 is screwed into the threaded hole in the middle of the base. The fixing rod 101 is embedded in the hole of the pressure rod 102, and the bottom extends into the groove of the lower half of the base 302. Then, after the spring retaining ring 400 is nested at the bottom of the pressure rod 102, the fixing screws on the side of the spring retaining ring 400 can be tightened to fix the spring retaining ring 400 to the pressure rod 102. The pressure sensor 801 is stuck in the groove on the lower surface of the sensor fixing boss 700 to prevent the sensor from sliding horizontally. Then, the top of the pressure sensor 801 is fixedly connected to the sensor fixing boss 700 by the fixing screw 601. Then, the bottom of the pressure sensor 801 is fixedly connected to the probe fixing boss 900 by the fixing screw 602. After nesting the spring at the bottom of the fixing rod 101, place the sensor fixing boss 700 along the slot at the bottom of the base, and then thread the fixing rod 101 into the small cylindrical groove on the upper surface of the sensor fixing boss 700 to complete the assembly of the pressure-display magnetic clamping device suitable for probes of multiple sizes.
[0028] During actual measurement, first clean the surface of the object being measured, then tighten both the fixing nut 200 and the pressure rod 102 to their loosest position. After placing the probe in the groove of the probe fixing boss 900, place the clamping device on the surface of the object being measured, and then gently press the clamping device to ensure that the strong rubidium magnet at the bottom is completely adsorbed on the surface of the object being measured. After connecting the pressure sensor interface 802 to the pressure display device, the pressure rod 102 can be tightened. When the displayed pressure value reaches the required value, the fixing nut 200 can be tightened to prevent the spring reaction force from exerting pressure on the pressure rod 102.
[0029] The utility model is compatible with probes of different sizes. By twisting the pressure rod, the pressure applied to the bottom probe can be changed, and the pressure size can be displayed in real time through an external pressure display device, thereby achieving the purpose of applying quantitative pressure.
