Description

Technical Field

[0001] The present application relates to the technical field of component detection equipment, and in particular to a component inner hole detection device. Background Art

[0002] After parts are produced, they usually need to be quality inspected to screen out unqualified products and ensure the production quality of parts.

[0003] There is a component for automobiles, such as Figure 1 As shown, its structure includes a shell 6, and a sleeve 7 is welded and formed at one end of the shell 6. After the production of the above parts is completed, they need to be inspected for quality. The inspection process mainly includes two steps. The first is a preliminary inspection of whether the parts are qualified, which mainly involves inspecting and judging the angle between the axis of the sleeve 7 and the surface of the shell 6 and the fixed position of the sleeve 7 to ensure that the position offset of the sleeve 7 is within the specified error range. At the same time, it is also necessary to ensure that the angle between the axis of the sleeve 7 and the surface of the shell 6 is about 90 degrees, so as to ensure that the quality of the parts meets the standards; the second is to conduct a secondary inspection on the qualified products, which mainly involves inspecting the position offset of the sleeve 7 to obtain the specific offset value of the sleeve 7, so as to facilitate subsequent use.

[0004] For the above-mentioned parts, the existing inspection method is usually to place the completed parts on the first workstation first, position the parts, and then determine whether the processing of the sleeve 7 on the shell 6 is qualified through manual inspection, and then transport them to the second workstation to perform offset detection on the position of the sleeve 7 on the shell 6; in actual use, since the above-mentioned inspection method requires the parts to be transported to the first workstation for inspection first, and then transported to the second workstation for inspection after the inspection is completed, the overall process is relatively cumbersome, especially when the number of parts to be inspected is large, the inspection process of the parts using the above-mentioned method is time-consuming and labor-intensive, which is not conducive to use.

If the column 22 can be embedded in the sleeve 7, it proves that the processing of the sleeve 7 is qualified, and if not, it proves that the processing of the sleeve 7 is unqualified.

[0039] Reference Figure 2 In order to prevent the first slide 12 and the second slide 13 from sliding and affecting the accuracy of the detection result of the sleeve 7, the first slide 12 and the second slide 13 need to be locked and fixed before detection. Therefore, a first locking component 4 and a second locking component 5 are provided on the base 11. The first locking component 4 is used to lock the first slide 12, and the second locking component 5 is used to lock the second slide 13.

[0040] Reference Figure 2 and Figure 5 The first locking assembly 4 includes a first mounting block 41, a first screw 42 and a first positioning block 43. The first mounting block 41 is fixed to the base 11 by bolts. The first mounting block 41 is L-shaped as a whole. The first screw 42 rotates on the first mounting block 41.

One end of the first screw 42 is located outside the first mounting block 41, and the other end passes through the first mounting block 41 and the first avoidance groove 431 and is threadedly connected to the first slide seat 12.

[0041] Reference Figure 2 and Figure 5 When in use, the first positioning block 43 is placed between the first mounting block 41 and the first slide 12, and then the first screw 42 is screwed to make the first slide 12 continuously approach the first positioning block 43 until the first mounting block 41, the first positioning block 43 and the first slide 12 abut against each other. At this time, the first screw 42 rotates to the limit value, and the first slide 12 is locked and fixed by the first screw 42.

[0042] Reference Figure 2 and Figure 5 The second locking assembly 5 includes a second mounting block 51, a second screw 52 and a second positioning block 53. The second mounting block 51 is fixed to the first slide 12 by bolts. The second mounting block 51 is L-shaped as a whole. The second screw 52 rotates on the second mounting block 51. The second positioning block 53 is located between the second mounting block 51 and the second slide 13. A second avoidance groove 531 is opened at one end of the second positioning block 53, and a second handle 532 is welded at the other end. One end of the second screw 52 is located outside the second mounting block 51, and the other end passes through the second mounting block 51 and the second avoidance groove 531 and is threadedly connected to the second slide 13.

[0043] Reference Figure 2 and Figure 5 When in use, the second positioning block 53 is placed between the second mounting block 51 and the second slide 13, and then the second screw 52 is screwed to make the second slide 13 continuously approach the second positioning block 53 until the second mounting block 51, the second positioning block 53 and the second slide 13 abut against each other. At this time, the second screw 52 rotates to the limit value, and the second slide 13 is locked and fixed by the second screw 52.

[0044] Reference Figure 2 Before performing a qualified inspection on the sleeve 7 on the component, the overall position of the inspection platform 1 needs to be calibrated to ensure that when the first screw 42 and the second screw 52 are rotated to the limit value, that is, the first slide 12 and the second slide 13 are locked and fixed, the axis of the support platform 14 located on the second slide 13 coincides with the axis of the sleeve 7 on the standard qualified component, so as to facilitate the subsequent inspection of the sleeve 7 on the component.

[0045] Reference Figure 2 and Figure 6A second detection structure 3 is also provided on the base 11. The second detection structure 3 is used to detect the specific offset value of the position of the sleeve 7 on the qualified component. The second detection structure 3 includes a detection pin 31, an abutment column 32, a first detection component 33 and a second detection component 34. The detection pin 31 is arranged above the bearing platform 14, the abutment column 32 is integrally formed on the detection pin 31, and the abutment column 32 and the detection pin 31 are coaxially arranged. The overall shape of the abutment column 32 is truncated cone, and the upper bottom surface of the abutment column 32 is arranged toward the bearing platform 14. The first detection component 33 is used to detect the displacement of the first slide 12, and the second detection component 34 is used to detect the displacement of the second slide 13.

[0046] Reference Figure 2 and Figure 6 When in use, after the processing quality inspection of the sleeve 7 on the component is passed, the positioning pin 21 is pulled out, and the first locking component 4 and the second locking component 5 are removed, and then the bottom end of the detection pin 31 is inserted into the positioning groove 15 for preliminary positioning, and then the detection pin 31 is continued to be moved downward, and the abutment column 32 is synchronously moved downward under the drive of the detection pin 31. When the bottom end of the abutment column 32 is inserted into the sleeve 7, the sliding direction of the abutment column 32 can be guided by the abutment force between the side wall of the abutment column 32 and the sleeve 7. The sliding of the abutment column 32 in the horizontal plane will drive the sliding of the detection pin 31. The sliding of the detection pin 31 drives the first slide 12 and the second slide 13 to slide relative to each other. After that, the displacement of the first slide 12 and the second slide 13 can be detected by the first detection component 33 and the second detection component 34, so as to obtain the specific offset value of the position of the sleeve 7.

[0047] Reference Figure 2 and Figure 6 The first detection component 33 includes a third mounting block 331 and a first micrometer 332. The third mounting block 331 is fixedly connected to the base 11 by bolts. The first micrometer 332 is plugged into the third mounting block 331, and the probe of the first micrometer 332 passes through the third mounting block 331 and abuts against the first slide 12. The second detection component 34 includes a fourth mounting block 341 and a second micrometer 342. The fourth mounting block 341 is fixedly connected to the first slide 12 by bolts. The second micrometer 342 is plugged into the fourth mounting block 341, and the probe of the second micrometer 342 passes through the fourth mounting block 341 and abuts against the second slide 13.

[0048] Reference Figure 2 and Figure 7When in use, after the sleeve 7 on the component has been inspected for quality, the staff can first observe and record the visual readings on the first micrometer 332 and the second micrometer 342. The value recorded this time is the standard visual reading of the processing position of the sleeve 7. After that, the position offset value of the sleeve 7 on the component is detected by the second detection structure 3. The first slide 12 and the second slide 13 after sliding can be detected by the first micrometer 332 and the second micrometer 342 respectively, and the second change visual reading can be recorded. The actual offset value of the position of the sleeve 7 on the component can be obtained by calculating the difference between the second detection visual reading and the first detection visual reading. It is simple and convenient to use.

[0049] The implementation principle of the embodiment of the present application is as follows: when in use, the position of the component is fixed, and the sleeve 7 on the component is located above the support platform 14, and then the processing quality of the sleeve 7 on the component is initially detected by the first detection structure 2, that is, by inserting the positioning pin 21 into the positioning groove 15, if the plug column 22 can be inserted into the sleeve 7 during the downward movement of the positioning pin 21, it can be proved that the processing quality of the sleeve 7 on the component is qualified, otherwise it is unqualified; after the qualified components are detected, the actual offset value of the position of the sleeve 7 is measured by the second detection structure 3, that is, the positioning pin 21 is first pulled out of the positioning groove 15, and then the first slide 12 and the second slide 13 are measured by the first micrometer 332 and the second micrometer 342. Perform an initial inspection and record the initial value, then open the first locking assembly 4 and the second locking assembly 5, and insert the inspection pin 31 into the positioning groove 15. During the downward movement of the inspection pin 31, the sliding direction of the abutment column 32 is guided by the inner wall of the sleeve 7. The horizontal sliding of the abutment column 32 will drive the first slide 12 and the second slide 13 to slide in the corresponding direction. When the abutment column 32 completely enters the sleeve 7, the first micrometer 332 and the second micrometer 342 can be used to perform a secondary inspection on the first slide 12 and the second slide 13 and record the changed values. After that, the actual offset of the sleeve 7 position can be obtained by calculating the difference between the secondary inspection value and the initial value. The overall measurement process is simple and convenient.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
