DETAILED DESCRIPTION
[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0029] The embodiment of the present application provides a bearing splitting inspection tool and inspection method, which can solve the technical problem that the bearing splitting inspection tool can only detect whether the splitting angle of the bearing is qualified, but cannot detect whether the arc position of the bearing meets the requirements.
[0030] See also Figure 1 and Figure 2 As shown, an embodiment of the present application provides a bearing splitting inspection fixture, which includes: a base 1, the base 1 is bolted with a positioning block 2, the positioning block 2 has an arc-shaped pressure-bearing surface 21, and the positioning block 2 is provided with standard circular arc reference surfaces 221 at both ends of the arc-shaped pressure-bearing surface 21, the bearing splitting inspection fixture also includes an upper limit measuring rod 3 and a lower limit measuring rod 4, the outer diameter of the upper limit measuring rod 3 is greater than the outer diameter of the lower limit measuring rod 4, the upper limit measuring rod 3 and the lower limit measuring rod 4 are used to be placed in the gap 5 formed between the arc surface to be measured of the bearing and the standard circular arc reference surface 221, so as to detect the position of the arc surface to be measured.
[0031] In this embodiment, the base 1 and the positioning block 2 are both made of steel material and are blackened on the surface. The lengths of the upper limit measuring rod 3 and the lower limit measuring rod 4 can be set to 45-55 mm. The positioning block 2 is provided with protrusions 22 at both ends of the arc-shaped pressure-bearing surface 21. The standard arc reference arc surface 221 is provided on one side of the protrusion 22. A gap 5 is formed between the standard arc reference arc surface 221 and the arc surface to be measured of the bearing shell. When the arc surface to be measured is parallel to the standard arc reference arc surface 221, the upper limit measuring rod 3 cannot slide in the gap 5, and the lower limit measuring rod 4 can slide in the gap 5, so it can be judged that the position of the arc surface to be measured of the bearing shell meets the requirements. The bearing shell splitting inspection fixture can realize counting type detection through metrological detection, thereby realizing the detection of the arc surface position to be measured of the bearing shell and avoiding the cumbersome steps required in the counting type detection process.
[0032] In this embodiment, the standard arc reference surface 221 is set at both ends of the positioning block 2, and the upper limit measuring rod 3 and the lower limit measuring rod 4 are placed in the gap 5 formed between the arc surface to be measured and the standard arc reference surface 221, so that the bearing splitting inspection tool can detect the position of the arc surface to be measured of the bearing, which solves the technical problem in the related technology that the bearing splitting inspection tooling can only detect whether the splitting angle of the bearing is qualified but cannot detect whether the arc position of the bearing meets the requirements.
[0033] Further, see Figure 1 and Figure 3 As shown, in some embodiments, the positioning block 2 is provided with an upper limit angle detection surface 23 on one side of the arc-shaped pressure-bearing surface 21, and a lower limit angle detection surface 24 is provided on the other side of the arc-shaped pressure-bearing surface 21, and the bearing splitting inspection fixture also includes a detection block 6, which is used to be slidably disposed on the upper limit angle detection surface 23 and the lower limit angle detection surface 24 to detect the splitting angle of the bearing.
[0034] In this embodiment, the thickness of the detection block 6 can be set to 1-3 mm, the length of the detection block 6 can be set to 20-40 mm, and the width of the detection block 6 can be set to 10-30 mm. Preferably, the thickness of the detection block 6 is set to 2 mm, the length of the detection block 6 is set to 30 mm, and the width of the detection block 6 is set to 20 mm. The detection block 6 cooperates with the upper limit angle detection surface 23 and the lower limit angle detection surface 24 to detect the split angle of the bearing shell using a measurement principle similar to a go / no-go gauge. During the detection process, the detection block 6 is close to the upper limit angle detection surface 23 or the lower limit angle detection surface 24 and slides toward the bearing shell. When the end face of the bearing shell is lower than the upper limit angle detection surface When the end face of the bearing is higher than the upper limit angle detection surface 23, the detection block 6 is blocked. When the detection block 6 can pass through the bearing at the upper limit angle detection surface 23 and is blocked at the lower limit angle detection surface 24, the split angle of the bearing is qualified. When the split angle of the bearing is large, the detection block 6 can be blocked at both the upper limit angle detection surface 23 and the lower limit angle detection surface 24, and the split angle of the bearing is unqualified. When the split angle of the bearing is small, the detection block 6 can pass through the bearing at both the upper limit angle detection surface 23 and the lower limit angle detection surface 24, and the split angle of the bearing is unqualified.
[0035] Further, see Figure 1 As shown, in some embodiments, the inclination angle of the upper limit angle detection surface 23 is less than or equal to the upper limit of the split angle to be measured, and the inclination angle of the lower limit angle detection surface 24 is greater than or equal to the lower limit of the split angle to be measured.
[0036] In this embodiment, exemplarily, the splitting angle to be measured can be set to 60°, and the tolerance range of the splitting angle to be measured can be set to ±2°, then the upper limit of the splitting angle to be measured is 62°, and the lower limit of the splitting angle to be measured is 58°, the inclination angle of the upper limit angle detection surface 23 is less than or equal to the upper limit of the splitting angle to be measured, the inclination angle of the upper limit angle detection surface 23 can be set to 61°50′~62°, the inclination angle of the lower limit angle detection surface 24 is greater than or equal to the lower limit of the splitting angle to be measured, and the inclination angle of the lower limit angle detection surface 24 can be set to 58°~58°10′. In other embodiments, exemplarily, the splitting angle to be measured can be set to 50°, and the tolerance range of the splitting angle to be measured can be set to ±1°, then the upper limit of the splitting angle to be measured is 51°, and the lower limit of the splitting angle to be measured is 49°, the inclination angle of the upper limit angle detection surface 23 can be set to 50°50′~51°, and the inclination angle of the lower limit angle detection surface 24 can be set to 49°~49°10′.
[0037] Further, see Figure 1 and Figure 3 As shown, in some embodiments, a limit block 25 is provided on one side of the upper limit angle detection surface 23 and the lower limit angle detection surface 24. When the detection block 6 is slid on the upper limit angle detection surface 23 or the lower limit angle detection surface 24, the limit block 25 abuts against the detection block 6.
[0038] In this embodiment, the limit block 25 abuts against the detection block 6, so that the detection block 6 can slide along the side of the limit block 25 on the upper limit angle detection surface 23 or the lower limit angle detection surface 24, so that the detection block 6 can cooperate with the upper limit angle detection surface 23 and the lower limit angle detection surface 24 to detect the split angle of the bearing.
[0039] Further, see Figure 1 As shown, in some embodiments, the bearing splitting inspection fixture also includes a clamping mechanism 7, and the clamping mechanism 7 includes a base 71 and a pressing portion 72. The base 71 is fixed to the base 1, and the pressing portion 72 is inserted into the base 71. The pressing portion 72 is provided with an arcuate surface that cooperates with the arcuate pressure-bearing surface 21, and is used to clamp the bearing.
[0040] In this embodiment, the base 71 can be set as an L-shaped column, and the L-shaped column includes a main board and a support plate. The main board is fixed to the base 1 and is located on one side of the positioning block 2. The main board and the support plate are perpendicular. The support plate is plugged with the pressing portion 72. The pressing portion 72 is located above the arc-shaped pressure-bearing surface 21. When testing is required, the split bearing is placed on the positioning block 2, and the pressing portion 72 presses the bearing through the arc-shaped surface and the arc-shaped pressure-bearing surface 21. In other embodiments, the base 71 can be set as an arc column.
[0041] Further, see Figure 1 As shown, in some embodiments, the pressing portion 72 includes a clamping wrench 721 and a pressure block 722, the clamping wrench 721 is inserted into the base 71, and one end of the clamping wrench 721 abuts against the pressure block 722, the pressure block 722 is provided with the arc surface, and the pressure block 722 cooperates with the arc-shaped pressure-bearing surface 21 to clamp the bearing shell.
[0042] In this embodiment, the clamping wrench 721 is located above the arc-shaped pressure-bearing surface 21, and the pressure block 722 is placed above the bearing shell, and the clamping wrench 721 is twisted so that one end of the clamping wrench 721 abuts against the pressure block 722. The pressure block 722 can then clamp the bearing shell, restore the bearing shell to its theoretical diameter, and restore the opening of the bearing shell to its theoretical opening width, thereby reducing the deviation of the detection result.
[0043] Further, see Figure 1 As shown, in some embodiments, the arc-shaped pressure-bearing surface 21 is provided with an elastic positioning pin 26 .
[0044] In this embodiment, the elastic positioning pin 26 can pass through the center hole of the bearing shell and abut against the pressure block 722, so that the bearing shell is positioned between the pressure block 722 and the positioning block 2, so that the bearing shell does not move during the detection process. The elastic positioning pin 26 can be set to a cone shape, so that the elastic positioning pin 26 can abut against the pressure block 722 and adapt to the center holes of different sizes without affecting the detection.
[0045] See also Figure 1-3 As shown, the embodiment of the present application provides a bearing detection method, which includes the following steps:
[0046] The first step: placing the split bearing shell on the arc-shaped pressure-bearing surface 21 of the positioning block 2 so that a gap 5 is formed between the arc surface to be measured of the bearing shell and the standard arc reference arc surface 221, wherein the positioning block 2 is bolted to the base 1.
[0047] Step 2: Insert the upper limit measuring rod 3 and the lower limit measuring rod 4 into the gap 5 respectively, wherein the outer diameter of the upper limit measuring rod 3 is greater than the outer diameter of the lower limit measuring rod 4.
[0048] Step 3: If the upper limit measuring rod 3 cannot slide in the gap 5, and the lower limit measuring rod 4 can slide in the gap 5, the position of the arc surface to be measured of the bearing shell meets the requirements, otherwise it does not meet the requirements.
[0049] Further, see Figure 1 and Figure 3 As shown, in some embodiments, an upper limit angle detection surface 23 and a lower limit angle detection surface 24 are provided on both sides of the positioning block 2, and the bearing segmentation detection method further includes:
[0050] Step 4: Slide the detection block 6 along the upper limit angle detection surface 23 on one side of the positioning block 2 , and slide along the lower limit angle detection surface 24 on the other side of the positioning block 2 .
[0051] Step 5: If the detection block 6 can pass through the bearing shell at the upper limit angle detection surface 23 and is blocked at the lower limit angle detection surface 24, the split angle of the bearing shell is qualified, otherwise it is unqualified.
[0052] In this embodiment, the first step, the second step and the third step in the bearing detection method are used to detect the position of the arc surface to be measured of the bearing, and the fourth step and the fifth step in the bearing detection method are used to detect the splitting angle of the bearing. The first step, the second step and the third step in the bearing detection method can be swapped with the fourth step and the fifth step to first detect the splitting angle of the bearing and then detect the position of the arc surface to be measured of the bearing.
[0053] Further, see Figure 1 As shown, in some embodiments, placing the split bearing on the arc-shaped pressure-bearing surface 21 of the positioning block 2 includes: placing the pressure block 722 on the arc-shaped pressure-bearing surface 21, driving the pressure block 722 to tighten the bearing by twisting the clamping wrench 721, and restoring the bearing to a theoretical diameter.
[0054] In this embodiment, before detecting the position of the arc surface to be tested of the bearing shell and the splitting angle of the bearing shell, the deformed bearing shell after splitting needs to be pre-processed to restore it to a theoretical arc state to reduce the deviation of the detection result.
[0055] When inspection is required, the split bearing is placed on the positioning block 2, the elastic positioning pin 26 passes through the center hole of the bearing, and the bearing is positioned, the pressing block 722 is placed on the bearing, and the clamping wrench 721 is twisted to make the pressing block 722 clamp the bearing to restore the bearing to the theoretical diameter, that is, the theoretical arc state, and the detection block 6 is slid on the upper limit angle detection surface 23 and the lower limit angle detection surface 24 to detect the split angle of the bearing. If the detection block 6 can pass through the bearing on the upper limit angle detection surface 23 and on the lower limit angle detection surface 24, If the angle limit detection surface 24 is blocked, the split angle of the bearing is qualified, otherwise it is unqualified. A gap 5 is formed between the arc surface to be measured of the bearing and the standard arc reference arc surface 221. The upper limit measuring rod 3 and the lower limit measuring rod 4 are inserted into the gap 5 to detect the position of the arc surface to be measured of the bearing. If the upper limit measuring rod 3 cannot slide in the gap 5 and the lower limit measuring rod 4 can slide in the gap 5, the position of the arc surface to be measured of the bearing meets the requirements, otherwise it does not meet the requirements. After the detection is completed, loosen the clamping wrench 721, take out the pressure block 722, and then take out the bearing.
