[0028] In the description of the present application, “plurality” means two or more.
[0029] In order to solve the technical problem of large measurement error of the support rod in the prior art, the present application provides a support rod auxiliary measurement tool 100, which includes a base plate 10, a cushion block 20 and a mounting seat 30. The support rod (not shown) is used to support the engine (not shown), and the support rod auxiliary measurement tool 100 is used to assist the CMM (Coordinate Measuring Machine) to establish a coordinate system for measuring parameters such as size. The support rod has a first end and a second end spaced apart along the length direction of the support rod.
[0030] Specifically, if Figure 1-Figure 3 As shown, the pad 20 is arranged on the bottom plate 10, and the pad 20 has an auxiliary measurement plane 21. The end surface of the first end of the support rod can be arranged in a close fit with the auxiliary measurement plane 21; the mounting seat 30 is arranged on the bottom plate 10, and the mounting seat 30 is used to mount the second end of the support rod. By setting the mounting seat 30 and the pad 20, the two ends of the support rod in the length direction can be relatively fixed to ensure the reliability of the measurement. For example, the auxiliary measurement plane 21 is a plane, and the auxiliary measurement plane 21 is located on the side of the pad 20 away from the bottom plate 10 (for example, as shown in FIG. 1 ). Figure 1 The end surface of the first end of the support rod can be the A reference plane of the support rod, and the Z direction of the coordinate system can be determined by the A reference plane during measurement.
[0031] Therefore, by setting the pad 20, the auxiliary measurement plane of the pad 20 is set to fit the end face of the first end of the support rod during measurement, so that the A reference plane of the support rod can be converted from the end face of the first end of the support rod to the auxiliary measurement plane 21, so as to prevent the uneven end face of the first end of the support rod from causing measurement errors, so as to improve the measurement accuracy and effect.
[0032] In some embodiments, Figure 1 As shown, the first end of the support rod has a connection hole, the cushion block 20 is provided with a positioning pin 40, and the first end of the support rod is sleeved on the positioning pin 40 through the connection hole. For example, the positioning pin 40 can be provided on the auxiliary measurement plane 21, so that, on the one hand, it can be convenient for positioning and installation; on the other hand, it can improve the installation reliability of the first end of the support rod, improve the fit, and ensure the measurement effect.
[0033] For example, the connection hole may be a through hole, the positioning pin 40 is inserted through the connection hole, the first end of the support rod may have a branch rod segment extending in a different direction from the main rod segment of the support rod, the branch rod segment may be connected to the end of the main rod segment, the connection hole may be formed in the branch rod segment and pass through the branch rod segment, the end face of the branch rod segment at the first end of the support rod may be the above-mentioned A reference, that is, the end face of the first end of the support rod refers to the end face of the branch rod segment. The inner peripheral wall of the connection hole may be the B reference of the support rod.
[0034] In some embodiments, Figure 1 As shown, the outer peripheral wall of the positioning pin 40 is arranged in close contact with the inner peripheral wall of the connecting hole. Therefore, when measuring, the B reference of the support rod can be converted from the inner peripheral wall of the connecting hole to the outer peripheral wall of the positioning pin 40 for easy measurement.
[0035] In some embodiments, Figure 1-Figure 3 As shown, the support rod auxiliary measurement tool 100 can also include a clamping mechanism 50, which is arranged on the base plate 10. The clamping mechanism 50 can provide a force to bring the auxiliary measurement plane 21 of the cushion block 20 and the end face of the first end of the support rod closer to each other, so as to improve the fit between the auxiliary measurement plane 21 and the end face of the first end of the support rod, so as to improve the measurement accuracy.
[0036] In some embodiments, the clamping mechanism 50 is at least one of a clamp or a fixture. For example, the clamping mechanism 50 can be a clamp. Before installing the support rod, the clamping part of the clamp can be opened. After the support rod is installed, the clamping part is closed and pressed above the first end of the support rod and the support rod is pressed downward to provide a force that brings the auxiliary measurement plane 21 of the cushion block 20 and the end face of the first end of the support rod closer to each other, so as to improve the fit between the two. Alternatively, the clamping mechanism 50 can be a fixture. The two ends of the fixture can be respectively located below the cushion block 20 and above the end face of the first end of the support rod. When clamped, the fixture can provide a force that brings the auxiliary measurement plane 21 of the cushion block 20 and the end face of the first end of the support rod closer to each other, so as to improve the fit between the two. Furthermore, the clamping mechanism 50 can include a clamp and a fixture or other clamping mechanism 50.
[0037] In some embodiments, Figure 1 As shown, the mounting seat 30 includes a main seat body 31 and a limiting block 32. The main seat body 31 is arranged on the base plate 10, and the limiting block 32 is fixed above the main seat body 31. The limiting block 32 has a limiting groove 321, and the second end of the support rod is embedded in the limiting groove 321. Among them, the second end of the support rod can be directly embedded in the limiting groove 321, or can be indirectly embedded in the limiting groove 321 through other components. By setting the limiting groove 321, positioning can be facilitated, and the installation reliability of the second end of the support rod can be improved. By setting the limiting block 32, it can be easy to replace, so as to set the limiting grooves 321 at different positions and different sizes to adapt to different types of support rods, so as to improve the applicability of the support rod auxiliary measurement tool 100.
[0038] In some embodiments, Figure 1As shown, the limiting groove 321 may include a first side wall 322 and a second side wall 323 that are arranged opposite to each other, and at least one of the first side wall 322 and the second side wall 323 is provided with an elastic plunger 324, and the elastic plunger 324 extends in the direction opposite to the first side wall 322 and the second side wall 323. For example, the first side wall 322 and the second side wall 323 may be provided with elastic plungers 324, and when the second end of the support rod is installed in the limiting groove 321, the two elastic plungers 324 may abut against the outer peripheral wall of the support rod, and the elastic plunger 324 may produce a certain deformation when subjected to force, thereby providing a stable supporting force, so as to realize that the second end of the support rod is embedded in the limiting groove 321 through the elastic plunger 324, so as to improve the installation reliability of the support rod, so as to improve the measurement accuracy. In addition, it can also be conducive to adapting to different types of support rods, so as to further improve the applicability of the support rod auxiliary measurement tool 100.
[0039] In some embodiments, Figure 1 As shown, both sides of the limit slot 321 in the up-down direction are open. Thus, the support rod can be inserted into the limit slot 321 to facilitate disassembly and assembly, and to facilitate adjustment of the relative positions of the two ends of the support rod. For example, the side of the limit slot 321 facing the cushion block 20 can be open to further facilitate disassembly and assembly and improve measurement efficiency.
[0040] In some embodiments, Figure 1 As shown, the orthographic projection of the auxiliary measurement plane 21 on the bottom plate 10 and the orthographic projection of the limiting groove 321 on the bottom plate 10 are staggered. Thus, the support rod can be tilted to simulate the use state of the support rod supporting the engine.
[0041] In some embodiments, Figure 1 and Figure 3 As shown, one side of the cushion block 20 has a positioning notch 22, for example, the positioning notch 22 is located on the side of the cushion block 20 away from the mounting seat 30. By providing the positioning notch 22, when the positioning pin 40 is not provided at the center of the cushion block 20 or the cushion block 20 is an asymmetric structure, it can be convenient for positioning and installation, and can play a fool-proof role.
[0042] For example, a handle 60 may be further provided on the base plate 10 , and there may be multiple handles 60 , so that the support rod can assist in the movement and measurement of the measuring tool 100 .
[0043] The support rod auxiliary measurement jig 100 of the embodiment of the present application can realize the measurement of the support rod on the support rod auxiliary measurement jig 100. By installing the support rod on the support rod auxiliary measurement jig 100, and fitting the end face (A reference plane) of the first end of the support rod with the auxiliary measurement plane 21 of the cushion block 20, so that the auxiliary measurement plane 21 replaces the A reference plane of the support rod for dimensional measurement, the measurement error can be reduced, and the support rod clamping method is simple and reliable, and the disassembly and assembly efficiency is high. The installation steps of the support rod can be: first open the pressure clamp, install the support rod on the support rod auxiliary measurement jig 100, and fit the A reference plane of the support rod with the auxiliary measurement plane 21, and then use the pressure clamp to clamp the support rod, and the A reference conversion of the support rod is measured at a point on the cushion block 20.
