Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, in particular to a quick-clamping type PCB board thickness measuring instrument. Background Technique

[0002] In the process of processing PCB, it is necessary to measure the thickness of the PCB board. When the volume of the PCB board to be measured is small and the operator can easily pick it up, the micrometer can be directly used to measure its thickness. However, in actual production, a considerable part of the PCB boards have a large volume, especially some special-shaped PCB boards with a large occupied area. The operator cannot easily pick up and fix them at a suitable angle. According to the publication number: CN206740038U, a PCB board thickness measuring instrument is disclosed, which includes a horizontally arranged base. A slide rail is arranged in the center of the base. An L-shaped mounting bracket movable along the slide rail is arranged on the slide rail. A groove for embedding the PCB board is formed on the mounting bracket. A measuring bracket is further arranged on the base. The measuring bracket is fixedly arranged at one end of the slide rail. A U-shaped measuring arm movable up and down is arranged on the measuring bracket. A micrometer for measuring the thickness of the PCB board is further arranged at the outermost end of the measuring arm. The PCB board to be measured is embedded in the groove on the mounting bracket, and the PCB board with a large volume can be conveniently fixed without the need for multiple operators. Then, the measuring arm is moved to the position where measurement is required to carry out the measurement.

[0025] Working principle: When in use, place the housing 1 in the required position, and then start the cylinder 2 to make the sliding plate 4 slide inside the housing 1 through the transverse guide rail 3. Then fix the plate 13 inside the clamping plate 11 through the clamping groove 12. When placing the plate 13, first pinch the lifting block 21 and lift it upward, so that the sliding rod 20 slides upward inside the top plate 18 through the sliding groove 19. At this time, the sliding rod 20 drives the pressing plate 22 to slide upward together. When the plate 13 is placed inside the clamping plate 11 through the clamping groove 12, release the lifting block 21. At this time, under the elastic force of the spring 23 itself, the pressing plate 22 can be driven to slide downward, so that the pressing plate 22 fixes the plate 13 inside the clamping plate 11. During use, the support plate 17 can be pinched and rotated, so that the support plate 17 drives the adjusting block 15 to slide through the fixing plate 16. At this time, the adjusting block 15 slides inside the clamping plate 11 through the adjusting groove 14 to meet different use requirements. During the clamping process, the position of the clamping plate 11 can be adjusted through the sliding block B10, and the sliding block A6 is used during the detection process, so that the sliding block A6 drives the measuring instrument body 8 and the guide plate 9 to slide through the fixed seat 7 to achieve the effect of detecting the plate 13. When the inclination angle of the plate 13 needs to be adjusted during the detection process, the electric telescopic rod 24 is used. At this time, since the mounting plate 25 is fixed inside the guide rail A5 through the mounting groove 26, the mounting plate 25 can drive the guide rail A5 to slide up and down to achieve the adjustment effect.
