Technical Field

[0001] The utility model relates to the technical field of mechanical parts detection devices, in particular to a detection device for the spatial dimensions of an end cover. Background Art

[0002] The end cover is used to cooperate with the end surface of the base. The Chinese patent with authorization announcement number CN219297004U discloses a hoisting anti-collision device, in which the specification is attached. Figure 5 The end face in the middle is to be connected with the end cover. The end cover is composed of a cylindrical, annular flange and two supporting foot surfaces. The end cover needs to be processed with a plurality of first mounting holes with a cylindrical axial array on the annular flange, and two second mounting holes need to be provided on each supporting foot surface. Since the end cover is an important component in many mechanical equipment, the dimensions between the processed first mounting holes and the second mounting holes and the end cover need to be detected after the end cover is processed. The existing detection device needs to use three-coordinate or laser tracking for detection to detect whether the position is qualified. This detection device is not only costly, but also requires a lot of time, which directly affects the production progress. Therefore, there is an urgent need for a detection device for the spatial size of the end cover, which is not only low in cost, but also can improve the detection efficiency, thereby improving the production progress.

[0021] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0022] Please refer to Figures 1 to 7 A device for detecting the spatial dimensions of an end cover 1, wherein the end cover 1 comprises a cylindrical shape 11, an annular flange 12 and two supporting footing surfaces 13, wherein the two supporting footing surfaces 13 are symmetrically connected to the outer circumference of the annular flange 12 with the axis of the cylindrical shape 11, and the two supporting footing surfaces 13 are perpendicular to the axis of the cylindrical shape 11, and the annular flange 12 is provided with a plurality of first mounting holes 121 arranged in an axial circumferential array of the cylindrical shape 11, and the supporting footing surface 13 is provided with two second mounting holes 131, including a left bracket and a right bracket. The left bracket includes a first locating pin 4, a second locating pin 5, a first locating plate 2 and a second locating plate 3. The first locating plate 2 is vertically connected to the second locating plate 3. The first locating plate 2 is provided with a first through hole 21, and the second locating plate 3 is provided with a second through hole 31. The first through hole 21 and the second through hole 31 are vertical and do not intersect. The second locating pin 5 is used to plug the first through hole 21 and the first mounting hole 121, and the first locating pin 4 is used to plug the second through hole 31 and the second mounting hole 131. The right bracket is mirrored to the left bracket.

[0023] In the above embodiment, the structure of the end cover 1 is as shown in the attached Figure 1, a total of five sizes, H, H1, E, E1 and E2, need to be tested to see if the distances between them meet the size standards. The testing principle is: the horizontal distance H3 from the end face of the annular flange 12 of the end cover 1 to the center of the second through hole 31 of the second positioning plate 3 is equal to the distance H1, the distance H4 from the supporting foot surface 13 of the end cover 1 to the first through hole 21 of the first positioning plate 2 is equal to the distance H, and the horizontal distance H5 from the second through hole 31 of the second positioning plate 3 to the first mounting hole 121 is tested, thereby indirectly determining whether E1 and E2 are symmetrical. The testing method is as follows: It should be noted that a stepped plane is provided on the second positioning plate 3. First, align the second through hole 31 of the second positioning plate 3 of the left bracket with the second mounting hole 131 of the supporting foot surface 13 of one of the end covers 1, and insert the first positioning pin 4 Insert and lock it with a locking nut to ensure that the second locating plate 3 of the left bracket is flush with the supporting base surface 13 of one of the end covers 1, and then insert the second locating pin 5 into the first through hole 21 of the first locating plate 2 of the left bracket and the first mounting hole 121 on the annular flange 12 of the end cover 1 in sequence. The same is true for the right bracket. If the second locating pin 5 can be inserted, it means that E, E1 and E2 meet the standards. If the second locating pin 5 cannot be inserted, it means that E, E1 and E2 do not meet the standards. When E1 and E2 meet the standards, it means that E also meets the standards. Finally, check the gap between the L-shaped plate of the left and right brackets and the end face of the annular flange 12. If this surface does not interfere with the outer circumference of the annular flange 12 or the gap meets the design requirements of the detection device, it means that H meets the standards.

[0024] As an optional embodiment, the first positioning plate 2 is an L-shaped plate having an A end 22 and a B end 23 , the first through hole 21 having the A end 22 , and the second positioning plate 3 is vertical and connected to the upper part of the B end 23 .

[0025] As an optional implementation, a reinforcing plate 6 is provided between the L-shaped plate and the second positioning plate 3 .

[0026] In the above embodiments, the reinforcement plate 6 is provided to improve the stability of the L-shaped plate and the positioning plate when the end cover 1 is detected.

[0027] As an optional implementation, a plurality of first through holes 21 with equal intervals are provided on the first positioning plate 2 along the X direction.

[0028] In the above embodiment, by providing a plurality of first through holes 21 with equal intervals, it is possible to adapt to the detection of end caps 1 of different specifications.

[0029] As an optional embodiment, the B end 23 of the first positioning plate 2 is provided with a flange ring 231 , and the first positioning pin 4 includes a first positioning column 41 and a second positioning column 42 . The first positioning column matches the second through hole 31 , and the second positioning column 42 matches the flange ring 231 .

[0030] In the above embodiment, when the second positioning column 42 is matched with the flange ring 231 , a locking nut is used to lock it, so that the first positioning pin 4 can better stabilize the bottom surface 13 and the second positioning plate.

[0031] As an optional implementation, the second positioning plate 3 is provided with a plurality of second through holes 31 at equal intervals along the cylindrical axial direction.

[0032] In the above embodiments, it can be checked whether the two second mounting holes 131 of the supporting foot surface 13 are located in the same plane.
