Technical Field

[0001] The utility model relates to the technical field of comprehensive inspection tools for motor end covers, in particular to an inspection tool for the position of bolt holes on a cover plate of a motor end cover. Background Art

[0002] The motor end cover is a shell cover in the motor structure that is used to seal and protect the entire internal circuit equipment, etc., and is used to isolate it from the outside and cut off direct contact with the outside. The motor end cover is usually fixed to the entire casing by bolts, which is convenient for assembly and disassembly and maintenance. After the motor end cover is produced, the bolt hole position formed by stamping needs to be inspected to determine whether the position and shape of the bolt hole are suitable for meeting the production specifications.

[0003] Nowadays, it is difficult to detect the bolt holes on the motor end cover. Because there are many bolt holes on the motor end cover and they are unevenly distributed, workers need to check and detect them one by one during the inspection.

[0030] Specifically, two through holes 12 are formed through the upper end of each fixing seat 6 and the L-shaped supporting seat 4, a fixing cylinder 13 is fixedly installed at the lower end of each through hole 12, and a sliding column 14 is movably provided through each fixing cylinder 13. The advantage is that the sliding column 14 can be extended and retracted up and down in the fixing cylinder 13 and the through hole 12, and is used to detect whether the position of the bolt hole on the end cover 7 to be detected corresponds correctly.

[0031] Specifically, the lower end of each sliding column 14 passes through the lower end of the through hole 12 and is fixedly installed with a fixed ball 15, and a return spring 16 is fixedly connected between the fixed ball 15 and the bottom of the fixed cylinder 13, and the upper end of each sliding column 14 passes through the upper end of the through hole 12 and a limit ring 17 is fixedly installed on the outer side. The advantage is that after the end cover 7 to be detected is placed, if the upper end of the sliding column 14 can pass through the bolt hole opened on the end cover 7 to be detected, it is judged that its position is correct, and the detection column 22 is inserted into the bolt hole and can push the sliding column 14 downward, it is judged that the position and size of the bolt hole meet the requirements, and after the detection column 22 is withdrawn, the sliding column 14 will return to its original position under the action of the return spring 16.

[0032] Specifically, a plurality of mounting seats 21 are fixedly mounted on the upper end of the substrate 1, and a plurality of mounting seats 21 are fixedly mounted on the upper end of each substrate 1, and each mounting seat 21 is provided with a detection column 22. Advantageously, the mounting seats 21 are used to place the detection columns 22 used by workers.

[0033] Embodiment 2:

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, as an improvement to the previous embodiment. Specifically, two guide posts 11 are fixedly mounted on the upper end of the base plate 1, and the two guide posts 11 are both arranged on the outside of the end cap 7 to be detected, and handles 20 are fixedly mounted on both ends of the base plate 1.

[0035] Specifically, a rotating plate 23 is fixedly installed on one side of each rotating block 10 located in the mounting frame 9, and the rotating plate 23 is connected to the mounting frame 9 by a fastening bolt 24. The end of the rotating block 10 away from the mounting frame 9 is bolted to the fixed plate 18, and the end of the fixed plate 18 away from the rotating block 10 is bolted to the pressing seat 19. The advantage is that the rotating block 10 can rotate, and when the end cover 7 to be detected is placed, the rotating block 10 is adjusted to a horizontal level, and the pressing seat 19 on the fixed plate 18 presses the end cover 7 to be detected on the upper end surface of each fixed seat 6, and the fastening bolt 24 is used to fix it.

[0036] When in use, first place the end cover 7 to be inspected on the upper end surface of each fixing seat 6, then rotate the rotating block 10 to adjust it to a horizontal level, and use the fastening bolts 24 to fix it. The clamping seat 19 on the fixing plate 18 presses the end cover 7 to be inspected on the upper end surface of each fixing seat 6. At this time, the sliding column 14 passes through the bolt holes on the end cover 7 to be inspected. If the sliding column 14 does not pass through, it is judged that the punching position of the bolt hole at this position is incorrect. The worker then takes out the inspection column 22 on the placement seat 21, and uses the inspection column 22 to pass through each bolt hole in turn. If the inspection column 22 can smoothly pass through the bolt hole and can push the sliding column 14 to slide downward, it is judged that the size of the hole meets the specification requirements. If not, it is judged that the size is incorrect.
