Figure 1 As shown, the flange shaft generally includes a shaft seat 1-1 and a shaft body 1-2 for connecting the bearing, but the shaft seat 1-1 and the shaft body 1-2 are not integrally formed during manufacturing, so the axis of the two may deviate (for example, the center axis of the shaft seat 1-1 and the center axis of the shaft body 1-2 are not in the same straight line, or the center axis of the shaft body 1-2 is tilted relative to the center axis of the shaft seat 1-1), resulting in poor performance of the flange shaft. Therefore, it is necessary to perform concentricity detection on the flange shaft to screen out defective flange shafts whose concentricity does not meet the use requirements.

[0040] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] Embodiment 1, as Figures 2 to 5 As shown, a flange shaft concentricity detection tool comprises a chassis 2, a support member 3, a limit guide member 4 and a concentricity detector. The concentricity detector can directly adopt the concentricity detector of the prior art.

[0042] The top of the chassis 2 is provided with a first mounting hole group and a second mounting hole group. Each of the first mounting hole groups includes at least three first mounting holes 2-1, and all of the first mounting holes 2-1 of each of the first mounting hole groups are located on the same circumference. Each of the second mounting hole groups includes at least two second mounting holes 2-2, and all of the second mounting holes 2-2 of each of the second mounting hole groups are located on the same circumference. The support member 3 is used to connect with any of the first mounting hole groups to support the bottom of the flange shaft. The limiting guide member 4 is used to connect with any of the second mounting hole groups to limit and guide the circumferential side of the flange shaft. The concentricity detector cooperates with the chassis 2, the support member 3, and the limiting guide member 4 to perform concentricity detection on the flange shaft.

[0043] like Figure 1As shown, the shaft seat 1-1 of the flange shaft includes a shaft seat disc 1-1-2 and a bottom convex ring 1-1-1. The first mounting hole group may include three first mounting holes 2-1 located on the same circumference, and the support member 3 can effectively support the bottom convex ring 1-1-1 of the flange shaft after being matched and connected with the first mounting holes 2-1. The second mounting hole group may include three second mounting holes 2-2 located on the same circumference, and the limiting guide member 4 can be matched and connected with the second mounting holes 2-1 to be in contact with the outer peripheral side of the shaft seat disc 1-1-2 of the flange shaft, thereby playing the role of radial limiting and circumferential guiding for the shaft seat disc 1-1-2 of the flange shaft.

[0044] In addition, a chassis 2 can be provided with multiple groups of first mounting holes and multiple groups of second mounting holes to facilitate the concentricity detection of flange shafts of different sizes.

[0045] The concentricity detection process of the flange shaft is as follows: first, select the appropriate first mounting hole group and second mounting hole group according to the size of the flange shaft to be detected; then connect the support member 3 with the first mounting hole 2-1 of the first mounting hole group, and connect the limiting guide member 4 with the second mounting hole 2-2 of the second mounting hole group; then put the entire flange shaft on the chassis 2, at this time, the bottom convex ring 1-1-1 of the flange shaft is just located on the top of the support member 3, and the outer peripheral side of the shaft seat plate 1-1-2 of the flange shaft is just in contact with the limiting guide member 4; finally, the shaft seat 1 of the flange shaft is successively checked by the concentricity detector. -1 (move the detection needle of the concentricity detector to contact and connect with the top surface, bottom surface or peripheral side surface of the shaft seat disk 1-1-2) and the shaft body 1-2 (move the detection needle of the concentricity detector to contact and connect with any peripheral side surface of the shaft body 1-2) for detection. During the detection process, the support member 3 and the limit guide member 4 need to cooperate to enable the flange shaft to rotate circumferentially. When the value detected by the shaft body 1-2 and the value detected by the shaft seat 1-1 are within the allowable error range, it means that the concentricity of the flange shaft meets the required requirements, otherwise it does not meet the requirements.

[0046] The flange shaft concentricity detection tool of the present invention can realize the rapid detection of the flange shaft concentricity, and the flange shaft concentricity detection operation is very simple.

[0047] like Figure 6 As shown, the support member 3 includes a connecting rod 3-1 that is connected to the first mounting hole 2-1, a supporting body 3-2 disposed at the axial top end of the connecting rod 3-1, a ball groove disposed at the top of the supporting body 3-2, and a ball 3-3 disposed in the ball groove. Most of the ball 3-3 is located in the ball groove and will not fall out of the ball groove.

[0048] The support member 3 is connected to the first mounting hole 2-1 through the connecting rod 3-1, which makes the support member 3 very easy to install. The support member 3 is load-bearing through the support body 3-2, so that the support member 3 has good stability. The support member 3 is contacted and connected with the flange shaft through the ball 3-3, so that the rotation resistance of the flange shaft is small, thereby facilitating the rotation operation of the flange shaft.

[0049] The inner peripheral wall of the first mounting hole 2-1 is provided with a connecting thread, and the connecting rod 3-1 is provided with a butt thread that cooperates with the connecting thread. The connecting rod 3-1 is connected to the first mounting hole 2-1 through a thread, which can improve the connection stability between the support member 3 and the chassis 2, avoid the loosening of the support member 3 during the rotation of the flange shaft, and thus make the flange shaft concentricity detection tooling of the present invention have a good use effect.

[0050] like Figure 7 As shown, the position limiting guide member 4 includes a bearing seat 4-1 and a bearing body 4-2. The bearing body 4-2 includes a moving bearing part and a static bearing part, the static bearing part is fixedly connected to the bearing seat 4-1, and the moving bearing part is in contact with the outer peripheral side of the shaft seat plate 1-1-2 of the flange shaft to cooperate with the flange shaft for rotation.

[0051] The bearing seat 4-1 includes a seat body 4-1-1 and a bearing mounting body 4-1-2 arranged on the top of the seat body 4-1-1, and the bearing seat 4-1 is provided with an assembly hole 4-1-3 vertically penetrating the bearing mounting body 4-1-2 and the seat body 4-1-1, and the assembly hole 4-1-3 is connected to the second mounting hole 2-2 through a connecting piece.

[0052] like Fig.10 As shown, the connecting member includes a threaded rod body 5-1 threadedly connected to the second mounting hole 2-2, and a bearing crimping body 5-2 arranged at the axial top end of the threaded rod body 5-1, and a bearing crimping body 4-1-4 arranged around the bearing mounting body 4-1-2 is provided on the top of the seat body 4-1-1.

[0053] When installing the limiting guide 4, you only need to place the bearing seat 4-1 on the corresponding second mounting hole 2-2 (the bearing body 4-2 has been previously connected to the bearing mounting body 4-1-2 of the bearing seat 4-1), and then put the threaded rod body 5-1 into the assembly hole 4-1-3 and thread the threaded rod body 5-1 to the second mounting hole 2-2 until the bearing crimping body 5-2 cooperates with the bearing crimping body 4-1-4 to tighten the static bearing part of the bearing body 4-2. The installation operation is simple and convenient.

[0054] The connecting piece also includes a limiting column 5-3 arranged between the threaded rod body 5-1 and the bearing crimping body 5-2, the diameter of the limiting column 5-3 is larger than the diameter of the threaded rod body 5-1, and the assembly hole 4-1-3 includes a rod body docking portion that is cooperatively connected to the threaded rod body 5-1, and a column docking portion that is cooperatively connected to the limiting column 5-3.

[0055] By setting the limiting column 5 - 3 and the column docking part, the connection effect between the connecting member and the limiting guide member 4 can be better and the connection stability can be higher, thereby improving the use effect of the limiting guide member 4.

[0056] The chassis 2 is provided with a limiting groove 2-3 at the position of the second mounting hole 2-2, which allows part of the seat body 4-1-1 to enter. The setting of the limiting groove 2-3 can play a role in horizontal limiting the seat body 4-1-1, so that the connection effect of the limiting guide member 4 and the chassis 2 is better and the connection structure is more stable.

[0057] The concentricity detector includes a base, the base is provided with a connecting hole, and the chassis 2 is also provided with a docking hole connected to the connecting hole through a second connecting member. The second connecting member can be a bolt. When the concentricity detector is connected to the chassis 2, it is only necessary to place the base of the concentricity detector on the chassis 2, and then connect the connecting hole with the docking hole through a bolt, so that the disassembly and assembly of the concentricity detector and the chassis 2 is also very simple.

[0058] Embodiment 2 is different from Embodiment 1 in that the position limiting guide member 4 further includes a bearing protection cover 4-3, such as Figure 8 and Fig. 9 As shown, the bearing protection cover 4-3 is provided with an axial through hole 4-3-1, and the axial through hole 4-3-1 is connected to the assembly hole 4-1-3 and the second mounting hole 2-2 through a connecting piece. The bearing protection cover 4-3 is arranged in a frustum shape, mainly used to prevent the flange shaft from damaging the bearing body 4-2 when placed, and plays a role in protecting the bearing body 4-2.

[0059] In this embodiment, the structure of the connecting member is as follows: Fig.11 As shown, specifically, the connecting member includes a threaded rod body 2 6-1 that is threadedly connected to the second mounting hole 2-2 and is arranged in cooperation with the assembly hole 4-1-3 and the axial through hole 4-3-1, and a limit head 6-2 arranged at the axial top end of the threaded rod body 2 6-1. The bottom of the bearing protection cover 4-3 is provided with a bearing crimping body 3 4-3-2, the top of the seat body 4-1-1 is provided with a bearing crimping body 2 4-1-4 arranged around the bearing mounting body 4-1-2, the axial through hole 4-3-1 includes a rod body docking portion 2 that is cooperatively connected to the threaded rod body 2 6-1, and a limit head accommodating portion that is cooperatively connected to the limit head 6-2.

[0060] When installing the limiting guide 4, it is only necessary to first place the bearing seat 4-1 on the corresponding second mounting hole 2-2 (the bearing body 4-2 has been previously connected to the bearing mounting body 4-1-2 of the bearing seat 4-1), then place the bearing protection cover 4-3 on the bearing seat 4-1 and make the axial through hole 4-3-1 of the bearing protection cover 4-3 dock with the assembly hole 4-1-3 of the bearing seat 4-1, then put the threaded rod body 2 6-1 into the axial through hole 4-3-1 and the assembly hole 4-1-3 and thread the threaded rod body 2 6-1 with the second mounting hole 2-2 until the bearing crimping body 3 4-3-2 and the bearing crimping body 2 4-1-4 press the static bearing part of the bearing body 4-2 (at this time, the limiting head 6-2 is just located in the limiting head accommodating part), and the operation is also very simple. In addition, the connecting piece can be rotated in conjunction with a rotating tool.

[0061] The above-described embodiments are only descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents for which protection is sought in the present invention have been fully recorded in the claims.
