Technical Field

[0002] To improve the efficiency of dimensional measurement for spaceborne products and reduce measurement errors, a semi-automatic measuring fixture was designed and manufactured. During the assembly of spaceborne product structures, the movable blocks, thermal pads, and other components used have height requirements, typically within millimeters.

This process is complex, manual measurement cannot control measurement errors, and repeated measurements are necessary for comparison. In production, this results in low efficiency, measurement errors, and high skill requirements for operators. Utility Model Content

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Reference Figures 1 to 8 A semi-automatic modular depth measurement fixture includes a base plate 1, columns 2, longitudinal beams 3, pre-tightening bolts 4, a sliding crossbeam 5, a slide block 6, a slide rail 7, a slide rail pressure plate 8, a fixing block 9, and a compression spring 10. The base plate 1 has four stepped holes for mounting the columns 2. The columns 2 are connected to the longitudinal beam 3 and the sliding crossbeam 5 to form the main frame. The sliding crossbeam 5 cooperates with the slide block 6. The slide block 6 is connected to the slide rail 7 and slides with the sliding crossbeam 5. The slide rail 7 has a stepped surface that slides with the fixing block 9. The fixing block 9 is used to mount measuring instruments.

[0026] The sliding beam 5 and the slide block 6 are both D-shaped structures, which restrict axial rotation after connection and provide a pressure plane for pre-tightening bolts.

[0027] The slide block 6 has 4 threaded holes for connection with the slide rail 7, and 1 central threaded hole for connection with the pre-tightening bolt 4. The slide rail 7 has 10 installation process holes and a slide rail stepped surface that cooperates with the fixing block 9 for sliding.

[0028] The fixing block 9 is fixed by the pressure of the slide rail pressure plate 8. The slide rail pressure plate 8, through the rotation of the pre-tightening bolt 4 to press the slide seat 6, simultaneously applies a certain pressure from the compression spring 10 to the pressure plate 8, thus restricting the movement position of the fixing block 9.

[0029] The key feature of this embodiment is that the sliding beam and slide block have a D-shaped structure at their mating points, which restricts axial rotation after connection and provides a pressure plane for the pre-tightening bolt. The slide block has four threaded holes for connection with the slide rail and one central threaded hole for connection with the pre-tightening bolt 4. The slide rail 7 has ten installation process holes and a slide rail stepped surface for sliding engagement with the fixing block 9. The fixing block 9 is fixed by pressure from the slide rail pressure plate 8. The slide rail pressure plate 8, through the rotation of the pre-tightening bolt 4 to press the slide block 6, simultaneously applies pressure to the spring 10, which transmits pressure to the pressure plate 8 to restrict the movement of the fixing block 9. The measuring sensor is placed on the fixing block, and adjusted to a suitable measuring position by moving the slide rail laterally and longitudinally according to the range of workpiece measurement required, and then locked. The workpiece to be measured is placed on the reference base plate. The operator only needs to move the product on the base plate, collect data using the sensor, and calculate the data, eliminating the need for manual measurement and improving work efficiency.
