Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1 to 4, the probe positioning, clamping and precise downward pressure regulating device of the present invention includes a platform 1 for placing a product to be measured, two X-direction moving mechanisms 2 disposed at two sides of the platform 1, a Y-direction cross bar 3 located above the platform 1, and a pressure detecting mechanism 4 capable of moving along the Y-direction cross bar 3, wherein two ends of the Y-direction cross bar 3 are respectively connected to the two X-direction moving mechanisms 2; the pressure detection mechanism 4 comprises a sliding groove block 41 penetrated by the Y-direction cross rod 3, a sleeve 42 arranged on the sliding groove block 41, and a pressure sensor 43, a spring 44 and a probe 45 which are arranged in the sleeve 42 from top to bottom, wherein the lower part of the sleeve 42 is provided with an opening for the probe 45 to penetrate out, the pressure sensor 43 is electrically connected with a controller, and the controller is electrically connected with a display screen 46 for displaying a pressure value; a probe opening is arranged at the side of the sleeve 42, and a probe 5 of the oscilloscope is inserted into the probe opening and can form a detection loop together with the probe 45 and a product to be detected. The X-direction moving mechanism 2 and the Y-direction cross bar 3 enable the pressure detecting mechanism 4 to adjust the horizontal position relative to the platform 1, thereby enabling the probe 45 to abut against a specific position of the product to be detected. When the probe 45 contacts the product to be tested, the product to be tested gives an upward elastic force to the probe 45, and the upward elastic force is transmitted to the sensing head of the pressure sensor 43 through the spring 44, the pressure sensor 43 obtains an analog signal and transmits the analog signal to the controller, and the controller converts the analog signal into a digital signal through A/D conversion and transmits the digital signal to the display screen 46 to display a corresponding pressure value. Under the condition that the probe 45 is in contact with the object to be detected, the probe 5 can hook the probe 44 to connect the loop of the oscilloscope. After the mainboard of the product to be detected is electrified, the voltage signal can be fed back to the oscilloscope, and the oscilloscope can read out a specific measurement value, so that poor detection can be completed. The utility model can utilize the probe and the probe to conduct the detection loop of the oscilloscope to carry out bad detection; meanwhile, the pressure sensor 43 is used for sensing the contact pressure of the probe 45 to the product, so that the pressure of the probe is controlled within a proper range, accurate positioning and accurate control of the lower pressure degree are realized, and the measuring accuracy and precision are improved.
As shown in fig. 2, the X-direction moving mechanism 2 includes a pair of X-direction slide bars 21 horizontally fixed to the side of the platform 1 and a side slider 22 moving along the X-direction slide bars 21, and the Y-direction slide bars 3 are connected to the side slider 22. The side slider 22 can move along the X-direction slide bar 21 without rotating, to provide stable support for the Y-direction slide bar 3.
As shown in fig. 2, both ends of the Y-direction cross bar 3 are connected to the side sliders 22 through a Z-direction moving mechanism 6, respectively, the Z-direction moving mechanism 6 includes a guide bar 61 erected on the side sliders 22, and an elevating block 62 connected to the Y-direction cross bar 3, the elevating block 62 has a through hole through which the guide bar 61 passes along the Z-direction, and the side sliders 22 are further provided with an adjusting member 63 for adjusting the height of the elevating block 62. When the probe 45 does not contact the product to be tested or the pressure on the product to be tested is too large, the Z-direction height of the Y-direction cross rod 3 can be adjusted by the adjusting piece 63 to ensure that the pressure of the probe 45 on the product to be tested is in a proper range.
As shown in fig. 2, the adjusting member 63 is a screw rod having one end rotatably connected to the side slider 22 and the other end vertically penetrating through the elevating block 62. The lead screw is threaded with the elevator block 62. Since the lifting block 62 can move only in the direction of the guide rod 61, the lifting block 62 can only lift the Y-direction cross bar 3 in the Z-direction when the lead screw is rotated.
As shown in fig. 2, the guide rod 61 has a side wall provided with a scale mark 61 for indicating the height of the elevator block 62. The contact between the probe 45 and the product to be measured requires the Y-bar 3 to be raised and lowered vertically, which requires equal adjustment distances on both sides. The graduation marks 61 enable the adjustment distance of the lifting block 62 to be visualized, which makes it possible to ensure more quickly the parallelism of the Y-bar 3 with respect to the surface of the platform 1.
As shown in fig. 3, the chute block 41 is provided with a first nut 47, and the tail end of the first nut 47 can abut against the Y-direction beam 3. After the position of the chute block 41 relative to the Y-direction cross bar 3 is adjusted, the first nut 47 is tightened to fix the positions of the chute block and the Y-direction cross bar so as to prevent measurement errors caused by position changes during measurement.
As shown in fig. 3 and 4, the sleeve 42 can move up and down relative to the chute block 41, and the chute block 41 is provided with a second nut 48 for fixing the relative position of the sleeve 42 and the chute block 41. The height of the sleeve 42 relative to the runner block 41 can be adjusted to a small extent, which ensures a certain compression of the spring 44 and the contact between the probe 45 and the product to be tested.
As shown in fig. 4, the sleeve 42 includes an inner cavity 421 for accommodating the probe 45, the spring 44 and the pressure sensor 43, the inner diameter of the inner cavity 421 is larger than the aperture of the opening, and the probe 45 has a stopper 451 blocked by the opening. The stop edge 451 prevents the probe 45 from being caught in the sleeve 42 and from being pushed out of the sleeve 42 by the elastic force of the spring 44.
As shown in fig. 3, a display screen 46 is provided on the chute block 41. The display screen 46 can display near the pressure sensor 43, which not only facilitates the adjustment of the pressure of the probe 45, but also eliminates the trouble of long-distance wiring.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the utility model.
