Description

Technical Field

[0001] The invention relates to the field of measurement technology, in particular to a single-bridge measuring instrument. Background Art

[0002] The three-coordinate measuring machine is a modern measuring tool that combines detection and statistical analysis. It is widely used in various industries, such as precision measurement of mold equipment, tooling fixtures, auto mold accessories, electronic and electrical structures. In actual application, due to certain requirements for the use of workshop space, the traditional three-coordinate measuring machine occupies a large space and needs to provide double-bridge support space for the three-coordinate measuring machine. In order to better match the production line and reduce the transportation consumption of products, the three-coordinate measuring machine needs to be installed at a suitable workstation. Then the double-bridge support will obviously take up more space and affect the installation of the three-coordinate measuring machine. Therefore, a single-bridge measuring machine is needed. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a single-bridge measuring instrument to solve the problem that the traditional measuring instruments in the prior art occupy a large space.

[0004] To achieve the above objectives and other related objectives, the present invention provides the following technical solutions:

[0005] A single-bridge measuring instrument comprises a base, a measuring column connected to the base in a forward and backward sliding manner, and a measuring component connected to the measuring column in a horizontal and vertical sliding manner;

[0006] The measuring assembly comprises a measuring base connected to the measuring column by longitudinal sliding, a probe connected to the measuring base by transverse sliding, a transverse movement assembly is arranged between the probe and the measuring base, a detection groove is arranged on the base and below the probe, and the detection groove is arranged to be recessed toward the center of the base.

[0007] To implement the above technical solution, a single-bridge supported measuring assembly can be realized by setting a measuring column in conjunction with the measuring assembly, so as to measure the workpiece to be measured on one side of the base, thereby reducing the space occupancy rate of the measuring equipment. A detection groove is provided on the base and below the probe, and the detection groove is recessed toward the center of the base, which can reduce the occupancy of the surrounding working space by the detection work surface.

[0008] In one embodiment of the present invention, the transverse movement assembly includes a transverse movement bin connected to the measuring column for vertical sliding, a transverse movement plate connected to the transverse movement bin for horizontal sliding, a probe beam is provided between the probe and the transverse movement plate, the probe beam extends out of the transverse movement bin, and a transverse movement drive member is provided in the transverse movement bin.

[0009] To implement the above technical solution, by setting up a transverse shift bin, on the one hand, a working space can be provided for the installation of the transverse shift drive component, and on the other hand, an installation space and guide processing can be provided for the transverse shift plate, thereby ensuring the stability of the transverse shift plate in the transverse shift bin. Extending the probe beam out of the transverse shift bin can ensure the stability and reliability of the detection working surface of the probe.

[0010] In one embodiment of the present invention, a probe rod is detachably connected between the probe beam and the probe, a positioning through hole is provided on the probe beam at the end connected to the probe rod, a positioning groove is provided on the probe rod at the end connected to the probe beam, and the positioning groove and the positioning through hole are connected by bolts.

[0011] To implement the above technical solution, the setting of the probe rod can provide stable support for the probe. The use of the positioning through hole in conjunction with the positioning groove can improve the connection stability and adjustment convenience between the probe rod and the probe beam. The positioning groove can adjust the connection position between it and the positioning through hole according to the needs of use, thereby meeting actual use needs.

[0012] In one embodiment of the present invention, a longitudinal guide rail is longitudinally arranged on the measuring column, the measuring base is slidably connected to the longitudinal guide rail, and a longitudinal screw is provided on one side of the longitudinal guide rail and between the measuring base and the measuring column.

[0013] To implement the above technical solution, the longitudinal guide rail can provide a guiding support for the measuring base, thereby improving the stability of the measuring base during longitudinal sliding. The longitudinal lead screw is arranged on one side of the longitudinal guide rail and between the transverse base plate and the measuring column, so that the space on the measuring column can be used more reasonably and the use of the longitudinal lead screw can be more stable.

[0014] In one embodiment of the present invention, a measuring guide rail is provided on the base and between the base and the measuring column, a measuring base is provided between the bottom of the measuring column and the measuring guide rail, the measuring base and the measuring guide rail are slidably connected, and a base driving member is provided on the base.

[0015] To implement the above technical solution, the setting of the measuring guide rail can provide a stable guiding support effect for the movement of the measuring column, and the setting of the measuring base can facilitate the cooperation with the measuring guide rail.

[0016] In one embodiment of the present invention, a base screw is provided at the movable end of the base driving member, the measuring base and the base screw are threadedly connected, the detection groove is provided between two sets of measuring guide rails in the base, and the base screw is provided in the detection groove.

[0017] To implement the above technical solution, a detection groove is provided between the two sets of measuring guide rails in the base, which can improve the supporting stability and reliability of the base screw on the measuring base. Since the base screw drives the entire measuring column part, its volume is relatively large. The detection groove is recessed into the inside of the base, which can reduce the space occupied by the base screw during use and make the overall design of the equipment more reasonable.

[0018] As described above, a single-bridge measuring instrument of the present invention has the following beneficial effects: by setting a measuring column in conjunction with the measuring component, a single-bridge supporting measuring component can be realized, and the workpiece to be measured on one side of the base can be measured, thereby reducing the space occupancy rate of the measuring equipment; a detection groove is provided on the base and below the probe, and the detection groove is recessed toward the center of the base, which can reduce the occupancy of the surrounding working space by the detection working surface; by setting a transverse shift bin, on the one hand, a working space can be provided for the installation of the transverse shift drive component; on the other hand, an installation space and guide processing can be provided for the transverse shift plate, thereby ensuring the stability of the transverse shift plate in use in the transverse shift bin; and the probe crossbeam is extended out of the transverse shift bin to ensure the stability and reliability of the detection working surface of the probe.
