DETAILED DESCRIPTION

[0025] 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.

[0026] The embodiment of the present application provides a detection tool for the proper assembly of the retaining spring, which can solve the technical problem that during the actual assembly process, the retaining spring may not be properly assembled while the air pressure in the cavity changes, but a qualified detection signal is still given, which cannot accurately reflect that the retaining spring is properly assembled.

[0027] See also Figure 1 and Figure 2As shown, the embodiment of the present application provides a detection tooling with a retaining spring assembled in place, which includes: a detection outer sleeve 1, a detection inner sleeve 2 is slidably installed in the detection outer sleeve 1, a contoured stop 21 is provided at the bottom of the detection inner sleeve 2, a displacement sensor 3 is abutted on the other side of the detection inner sleeve 2, and the displacement sensor 3 is connected to a sensor guide column 4, the detection outer sleeve 1 is fixedly provided with a sleeve 5, a sensor signal receiving end is fixedly provided in the sleeve 5, the sensor signal receiving end is electrically connected to the displacement sensor 3, the sensor signal receiving end is spaced apart from the sensor guide column 4, and the sensor guide column 4 is located between the sensor signal receiving end and the displacement sensor 3.

[0028] In this embodiment, the detection outer sleeve 1 and the detection inner sleeve 2 are both provided with a plurality of through holes to reduce the weight of the detection tooling. The detection outer sleeve 1 and the detection inner sleeve 2 can be set to metal materials. The displacement sensor 3 displays height data through an amplifier, and the amplifier is electrically connected to the displacement sensor 3. The sensor guide column 4 includes a shell and an elastic measuring element. The shell is fixed to the detection outer sleeve 1, and the elastic measuring element is slidably installed in the shell. The inner wall of the shell is fixed with a grating and a grating scale. The grating and the grating scale are arranged relative to each other. The elastic measuring element moves up and down in the shell, and the displacement sensor 3 outputs corresponding height data. When the retaining spring 9 is inserted into the retaining spring groove and assembled in place, the detection tooling is assembled to the input shaft sub-assembly, the retaining spring 9 contacts the detection inner sleeve 2, and the retaining spring 9 enters the imitation stop 21. The detection inner sleeve 2 moves upward under the applied thrust, and drives the elastic measuring element to move upward. The height change of the elastic measuring element relative to the grating scale is small, and the displacement sensor 3 outputs The height data outputted is within the specified qualified range, and the indicator light of the detection tooling is on, the input shaft sub-assembly is qualified in the assembly of the retaining spring, when the retaining spring 9 is inserted into the retaining spring groove and is not assembled in place, the retaining spring 9 will not enter the profiling stop 21, and the detection inner sleeve 2 moves upward under the applied thrust, and drives the elastic measuring element to move upward, and the height change of the elastic measuring element relative to the grating scale is large, the height data outputted by the displacement sensor 3 is not within the specified qualified range, the input shaft sub-assembly is unqualified in the assembly of the retaining spring, and the displacement sensor 3 can be set as a pulse sensor. Demonstratively, when the distance between the sensor signal receiving end and the sensor guide column 4 is less than 12㎜, the displacement sensor 3 receives the signal and outputs the height data, the detection tooling can accurately reflect the state of the retaining spring being assembled in place, and effectively prevent the input shaft sub-assembly that is qualified in the inspection from flowing out because the retaining spring is not fully assembled into the retaining spring groove, and the operator can adjust the retaining spring 9 in time according to the height data, and the detection tooling has a simple structure, is light and easy to operate, and can be used for the assembly in place detection of a large number of input shaft sub-assemblies. In other embodiments, the sensor guide column 4 can be slidably installed on the detection outer sleeve 1, the detection tooling is assembled to the input shaft sub-assembly, the retaining spring 9 is in contact with the detection inner sleeve 2, the detection inner sleeve 2 moves upward under the applied thrust, and drives the sensor guide column 4 to move upward, the distance between the sensor guide column 4 and the sensor signal receiving end changes, and the displacement sensor 3 outputs corresponding height data.

[0029] In this embodiment, the detection inner sleeve 2 having the profiled stop 21 is slidably installed in the detection outer sleeve 1, and the detection inner sleeve 2 abuts against the displacement sensor 3. When the detection tooling is used to detect the retaining spring 9, if the retaining spring 9 is inserted into the retaining spring groove and assembled in place, the retaining spring 9 will enter the profiled stop 21, the detection inner sleeve 2 is stressed and drives the elastic measuring element in the sensor guide column 4 to move upward, the upward movement distance of the elastic measuring element is small, the height data output by the displacement sensor 3 is small, the height data output by the displacement sensor 3 is within the specified qualified range, and the retaining spring of the input shaft sub-assembly is assembled properly. If the retaining spring 9 is inserted into the retaining spring groove and not assembled in place, the retaining spring 9 will not enter the profiled stop 21, the detection inner sleeve 2 is subjected to force and drives the elastic measuring element to move upward, the upward movement distance of the elastic measuring element is large, the height data output by the displacement sensor 3 is large, the height data output by the displacement sensor 3 is not within the specified qualified range, and the input shaft sub-assembly assembly retaining spring is unqualified. This solves the problem in the related technology that during the actual assembly process, when the retaining spring is installed in place, the detection tooling may not be assembled in place and the air pressure in the cavity may change, and a qualified detection signal is still given, which cannot accurately reflect the technical problem that the retaining spring is assembled in place.

[0030] Further, see Figure 2 As shown, in some embodiments, an elastic reset component 6 is fixedly provided on the side of the detection inner sleeve 2 close to the sleeve 5, and an end cover 7 is fixedly provided on the side of the detection outer sleeve 1 close to the sleeve 5. The end cover 7 is fixed to the sleeve 5, and the end cover 7 abuts against the elastic reset component 6.

[0031] In this embodiment, the elastic reset component 6 is fixed to the detection inner sleeve 2, and the elastic reset component 6 is in contact with the end cover 7. When the detection fixture is assembled to the input shaft sub-assembly, the detection inner sleeve 2 is forced to move upward, and the elastic reset component 6 is compressed under the action of the detection inner sleeve 2. After the detection fixture completes the detection, the detection inner sleeve 2 can move downward and reset under the action of the elastic reset component 6. In other embodiments, other elastic components can be fixed on the side of the detection inner sleeve 2 close to the sleeve 5 to achieve automatic reset of the detection inner sleeve 2 after the detection fixture completes the detection.

[0032] Further, see Figure 2 As shown, in some embodiments, the displacement sensor 3 is inserted into the end cover 7 .

[0033] In this embodiment, the tail of the displacement sensor 3 is fixed to the end cover 7, and the head of the displacement sensor 3 is in contact with the top of the detection inner sleeve 2, so that the detection inner sleeve 2 can drive the displacement sensor 3 to move upward during the detection process, and drive the elastic measuring element in the sensor guide column 4 to move upward to obtain height data, and at the same time, the detection inner sleeve 2 can drive the displacement sensor 3 to reset during the resetting process. In other embodiments, the sensor guide column 4 can be inserted into the end cover 7, and the head of the displacement sensor 3 is in contact with the top of the detection inner sleeve 2. During the detection process, the detection inner sleeve 2 can drive the sensor guide column 4 to move upward through the displacement sensor 3 to change the distance between the sensor guide column 4 and the sensor signal receiving end.

[0034] Further, see Figure 2 As shown, in some embodiments, the elastic reset assembly 6 includes a spring support 61, which is fixed to the detection inner sleeve 2, and the spring support 61 is sleeved with a reset spring 62, and one end of the reset spring 62 abuts against the end cover 7.

[0035] In this embodiment, the spring support 61 is bolted to the detection inner sleeve 2, and the spring support 61 is used to limit the axial movement of the reset spring 62 to ensure that the reset spring 62 is subjected to force along its axial direction. The reset spring 62 is sleeved on the spring support 61, and one end of the reset spring 62 is in contact with the end cover 7, so that the detection inner sleeve 2 can be reset under the action of the reset spring 62 after the detection of the detection tool is completed, thereby ensuring the accuracy of the next detection. In other embodiments, one end of the reset spring 62 is fixed to the end cover 7.

[0036] Further, see Figure 2 As shown, in some embodiments, the spring support 61 is further sleeved with an adjustment pad 63 , and the adjustment pad 63 abuts against the other end of the return spring 62 .

[0037] In this embodiment, the return spring 62 is flexibly connected to the spring support 61 through the adjustment pad 63 to extend the service life of the return spring 62. The adjustment pad 63 is used to limit the axial movement of the return spring 62 to ensure that the return spring 62 is evenly stressed.

[0038] Further, see Figure 1 and Figure 2 As shown, in some embodiments, the detection inner sleeve 2 is provided with a sleeve 8 on its outer sleeve, and the sleeve 8 is slidably disposed in the detection outer sleeve 1 .

[0039] In this embodiment, the detection outer sleeve 1 and the detection inner sleeve 2 are clearance-matched, and the clearance between the detection outer sleeve 1 and the detection inner sleeve 2 can be set to 0.3-0.6 mm. The bushing 8 is sleeved on the detection inner sleeve 2 to play a guiding role, ensuring that the detection inner sleeve 2 slides up and down along its axis in the detection outer sleeve 1, and the detection inner sleeve 2 can slide to install the bushing 8. In other embodiments, the detection inner sleeve 2 can be fixed to the bushing 8.

[0040] Further, see Figure 1 and Figure 2 As shown, in some embodiments, the bushing 8 is provided with an annular groove 81 , and the detection sleeve 1 is provided with a limiting hole. The detection sleeve 1 passes through the limiting hole and enters the annular groove 81 to limit the bushing 8 by means of a top screw.

[0041] In this embodiment, the inner diameter of the bushing 8 can be set to be smaller than the outer diameter of the top of the detection inner sleeve 2. The top screw passes through the limiting hole and enters the annular groove 81 to fix the detection outer sleeve 1 to the bushing 8, so as to lock the bushing 8 when not in use, thereby limiting the detection inner sleeve 2 and preventing the elasticity of the elastic reset component 6 from being reduced under the action of gravity, resulting in the detection inner sleeve 2 being unable to automatically reset, thereby reducing the accuracy of the detection tooling.

[0042] Further, see Figure 2 As shown, in some embodiments, the inner diameter of the contoured stop 21 is set to 35.7-35.9 mm, and the depth of the contoured stop 21 along the axial direction of the detection inner sleeve 2 is set to 1.02-1.22 mm.

[0043] In this embodiment, Figure 3 As shown, the original outer diameter of the retaining spring 9 is 35.1-35.2 mm, and the thickness of the retaining spring 9 is set to 1.5-1.52 mm. Figure 4 As shown, when the retaining spring 9 is inserted into the retaining spring groove and assembled in place, the outer diameter of the retaining spring 9 is expanded to 35.4-35.6 mm, and the end face of the retaining spring 9 is perpendicular to the axis of the input shaft sub-assembly, the expanded outer diameter of the retaining spring 9 is smaller than the inner diameter of the imitation stop 21, and the retaining spring 9 can enter the imitation stop 21 of the detection tooling, and the detection inner sleeve 2 is subjected to force and drives the elastic measuring element in the sensor guide column 4 to move upward, and the upward movement distance of the elastic measuring element in the sensor guide column 4 is small, and the height data output by the displacement sensor 3 is within the specified qualified range. At the same time, the indicator light of the detection tooling is on, and the detection display of the detection tooling is qualified, as shown in FIG. Figure 5As shown, when the retaining spring 9 is inserted into the retaining spring groove but not assembled in place, the outer diameter of the retaining spring 9 is expanded to 37.7-37.9 mm, and the end face of the retaining spring 9 is inclined to the axis of the input shaft sub-assembly, the expanded outer diameter of the retaining spring 9 is larger than the inner diameter of the imitation stop 21, and the retaining spring 9 cannot enter the imitation stop 21 of the detection tooling, and the retaining spring 9 contacts the end face of the bottom of the detection inner sleeve 2. The detection inner sleeve 2 is subjected to force and drives the elastic measuring element to move upward. The upward movement distance of the elastic measuring element in the sensor guide column 4 is large, and the height data output by the displacement sensor 3 is not within the specified qualified range. The detection tooling detection shows that it is unqualified, which prevents the shaft parts with inadequate retaining springs from entering the next process and ensures the assembly quality. In other embodiments, the sensor guide column 4 is slidably installed on the end cover 7. When the retaining spring 9 is inserted into the retaining spring groove and assembled into place, the retaining spring 9 can enter the profiling stop 21 of the detection tooling. The detection inner sleeve 2 is subjected to force and drives the sensor guide column 4 to move upward. When the retaining spring 9 enters the profiling stop 21, the upward movement distance of the sensor guide column 4 is smaller than that when the retaining spring 9 does not enter the profiling stop 21. The height data output by the displacement sensor 3 is within the specified qualified range. At the same time, the indicator light of the detection tooling is on, and the detection display of the detection tooling is qualified.

[0044] Further, see Figure 1 and Figure 2 As shown, in some embodiments, the sleeve 5 includes an extension sleeve 51, the extension sleeve 51 is fixed to the detection sleeve 1, the extension sleeve 51 is connected to a lifting eye stud 52, and the sensor signal receiving end is fixed in the lifting eye stud 52.

[0045] In this embodiment, the extension sleeve 51 is bolted to the end cover 7, and the extension sleeve 51 is fixed to the detection sleeve 1 through the end cover 7. A sensor guide column 4 installation cavity is formed in the extension sleeve 51, and a sensor signal receiving end installation cavity is formed in the lifting ring stud 52. The extension sleeve 51 and the lifting ring stud 52 are threadedly connected to form a whole, so that the sensor guide column 4 and the sensor signal receiving end can be arranged relative to each other in the inner cavity of the sleeve 5, so as to realize the detection of height data of the displacement signal of the elastic measuring element in the sensor guide column 4 through the sensor signal receiving end in the sleeve 5.

[0046] Further, see Figure 1 and Figure 2 As shown, in some embodiments, a lifting ring 53 is fixedly provided on a side of the lifting ring stud 52 away from the extension sleeve 51 .

[0047] In this embodiment, the lifting ring 53 is provided on the top of the lifting ring stud 52, and the lifting ring 53 is used to lift the detection tool when not in use, so as to facilitate the detection tool to be taken and used at any time.
