In order to make the objectives, features and advantages of the present utility model more obvious and understandable, please refer to the accompanying drawings.

[0024] It should be noted that the structures, proportions, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present utility model. Therefore, they do not have any technical substance. Any modification of the structure, change in the proportional relationship or adjustment of the size, without affecting the effects that the present utility model can produce and the objectives that can be achieved, should still fall within the scope covered by the technical content disclosed by the present utility model.

[0025] The following describes the specific structure of a testing device for a bearing box:

[0026] Please refer to Figures 1 to 4 , the testing device for a bearing box in this embodiment includes a frame 1. The frame 1 includes a first carrier 101 and a second carrier 102. The testing device further includes a rotating assembly 2 and a lifting assembly 3. A part of the rotating assembly 2 and the lifting assembly 3 is connected to the first carrier 101.

[0027] Further, the rotating assembly 2 includes a support plate 201 and a motor 202. The support plate 201 is fixedly connected to the first carrier 101, and the motor 202 is connected to the support plate 201. The rotating assembly 2 further includes a first gear 203 and a second gear 204. The first gear 203 is connected to the motor 202, and the first gear 203 meshes with the second gear 204. Driven by the motor 202, the first gear 203 rotates, thereby driving the second gear 204 to rotate passively.

[0028] Further, the rotating assembly 2 further includes a clamping member 205 and a clamping element 206. The clamping member 205 is connected to the second gear 204. In this embodiment, the clamping member 205 and the second gear 204 are connected by bolts. When the second gear 204 rotates, the clamping member 205 also rotates. A part of the clamping element 206 is externally connected to the clamping member 205, and another part of the clamping element 206 is externally connected to the bearing housing part. The clamping member 205 abuts against the bearing housing.

[0029] Further, the clamping element 206 is provided with a first hole 2061, that is, the first hole 2061 is in clearance fit with the clamping member 205 and the bearing housing. A recessed portion 2062 is further provided on the surface of the clamping element 206, and a second hole 2063 penetrating through the clamping element 206 is further provided in the recessed portion 2062. The forming path of the second hole 2063 does not intersect with the first hole 2061. In this embodiment, the clamping element 206 is clamped to the clamping member 205 and the bearing housing by bolts through the second hole 2063, so that when the clamping member 205 rotates, the bearing housing also rotates synchronously.

[0030] Further, the lifting assembly 3 includes a lifting member 301 and a bearing member 302. The lifting member 301 includes a housing 3011 and a moving member 3012. Both the housing 3011 and the bearing member 302 are fixedly connected to the first carrier 101. The moving member 3012 is movably engaged with the bearing member 302 relative to the housing 3011 in a first direction. In this embodiment, the first direction is Figure 3 The vertical direction shown is the direction perpendicular to the horizontal ground in the working state.

[0031] Further, the carrier 302 is connected to the clamping member 205, and a buffer portion 5 and a bearing portion 6 are further provided between the carrier 302 and the clamping member 205. A force is applied to the carrier 302 through the movement of the moving member 3012, and then the carrier 302 transmits the force to the clamping member 205 through the buffer portion 5 and then to the bearing housing. A protrusion 2051 is provided on the surface of the clamping member 205, and the bearing portion 6 is clamped to the protrusion 2051, ensuring the stable rotation of the clamping member 205 relative to the carrier 302.

[0032] Further, the inspection device further includes a limit assembly 4, and the limit assembly 4 and the lifting assembly 3 cooperate synchronously. The limit assembly 4 is disposed on the second carrier 102. The limit assembly 4 includes a cylinder 401 and a limiting member 402. The cylinder 401 and the limiting member 402 are connected and are both uniformly disposed on the second carrier 102. The limiting member 402 is further provided with a third hole 4021. Preferably, in this embodiment, the limiting member 402 is fixed to the second carrier 102 by bolts. When the bolts are loosened, the cylinder 401 can push the limiting member 402 to move in the third hole 4021, thereby realizing the limitation of the bearing housing by the limiting member 402 and preventing the bearing housing from moving in the first direction due to the force of the lifting assembly 3.

[0033] The following describes the specific working process of the inspection device for a bearing housing according to an embodiment of the present invention as follows:

[0034] First, the bearing housing connected to the clamping member 205 is synchronously rotated through the rotating assembly 2, and then a force in the first direction is simulated on the bearing housing as needed through the lifting assembly 3. At the same time, the bearing housing is limited through the limit assembly 4, ensuring that the bearing housing does not move in the first direction while being stressed. Through the combined action of the rotating assembly 2, the lifting assembly 3, and the limit assembly 4, an integrated inspection function is realized to observe the quality performance of the bearing housing, such as whether there is oil leakage in the bearing housing during rotation, thereby ensuring the stable and efficient operation of the screw pump after operation, and at the same time reducing the equipment failure rate and maintenance cost.

[0035] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0036] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
