[0003] For example, CN214036530U discloses a bearing support seat structure based on precision casting, and the key points of its technical solution are: comprising a fixed seat, a support seat body is fixedly installed on the upper surface of the fixed seat, a thread groove is provided inside the support seat body, a bearing groove is provided inside the thread groove, and a spacer ring is fixed between the thread groove and the bearing groove, a fixing ring is fixedly installed on the inner side of the bearing groove, a rear through hole is provided on the back of the support seat body, a fixing sleeve is threadedly sleeved inside the thread groove, symmetrical handles are fixedly installed on both sides of the fixing sleeve, a front through hole is provided on the front surface of the fixing sleeve, a base is provided directly below the fixed seat, and the fixed seat and the base are connected by a screw rod, and a worm gear mechanism connected to the screw rod is provided inside the fixed seat, and mounting holes are provided on both sides of the upper surface of the base; the bearing is fixed mainly by rotating the fixing sleeve, and the installation and disassembly of the support seat can be completed without using bolts to fix it, which effectively saves installation time, and the lifting of the fixed seat can be adjusted by the worm gear mechanism, which enhances practicality.

[0004] The above-mentioned support structure for precision bearings still has certain shortcomings: since the bearing models that can be installed on the support structure are fixed, once the size of the precision bearing to be installed is smaller than the size of the support structure, the precision bearing will become loose and will no longer be able to play a supporting role. Therefore, it is necessary to provide a support structure for precision bearings. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a support structure for a precision bearing to solve the problems existing in the prior art.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a support structure for a precision bearing, comprising a bearing support seat, the upper surface of the bearing support seat is penetrated by a plurality of connecting through holes in a rectangular array, the top end of the back side of the bearing support seat is fixedly connected with two stable connecting plates symmetrically along the center, a first hydraulic telescopic rod is detachably installed on one side of the front side of the stable connecting plate, a stable connecting assembly is arranged inside the bearing support seat, two installation grooves are symmetrically arranged on the back side of the stable connecting assembly along the center, and a limiting ring is bonded inside the installation groove.

[0007] There are several connecting through holes, and the connecting through holes are equally divided into two groups. The depth of the connecting through holes is greater than the depth of the mounting groove.

[0008] Among them, one end of the first hydraulic telescopic rod is adapted to the inside of the limiting ring, and the limiting ring is made of a rubber component.

[0009] There are two limit rings, and the thickness of the limit rings is smaller than the depth of the installation groove.

[0010] The stable connection assembly includes a stable connection ring and a connection base, the interior of the stable connection ring is symmetrically fixedly connected with two connection bases along the center, and the surface of the stable connection ring is adapted to the interior of the bearing support seat.

[0011] Wherein, a second hydraulic telescopic rod is detachably mounted on the side wall of the connecting base, and an arc-shaped connecting plate is fixedly connected to one end of the second hydraulic telescopic rod.

[0012] Wherein, the side wall of the arc-shaped connecting plate is in contact with the surface of the precision bearing, and the material of the arc-shaped connecting plate is a rubber component.

[0013] The beneficial effects of the above technical solution of the utility model are as follows:

[0014] 1. In the above scheme, the support structure is provided with a stable connection component. When the size of the precision bearing to be supported is smaller than the installation size of the bearing support seat, the precision bearing to be supported is placed at the center of the two sets of arc-shaped connecting plates, and then the second hydraulic telescopic rod is started to extend and retract. Then the second hydraulic telescopic rod drives the arc-shaped connecting plate to move until the lower surface of the arc-shaped connecting plate is tightly fitted with the surface of the precision bearing, so that the precision bearing can be fixed inside the bearing support seat. Because the second hydraulic telescopic rod has the function of automatic extension and retraction, it can control the distance between the two sets of arc-shaped connecting plates. Even if the size of the precision bearing to be supported is smaller than the installation size of the bearing support seat, it will not cause the precision bearing to loosen, thereby enhancing the practicality of the device;

[0015] 2. In the above scheme, the support structure is provided with a stable connection plate, a first hydraulic telescopic rod, an installation groove and a limit ring. When the stable connection assembly needs to be replaced, the first hydraulic telescopic rod is started to drive the stable connection assembly to move until the stable connection assembly is moved out of the interior of the bearing support seat, and then the stable connection assembly is held and a certain external force is applied to the outside to separate the stable connection assembly from the first hydraulic telescopic rod. Because one end of the first hydraulic telescopic rod is clamped in the inside of the limit ring, it can be directly pulled out, thereby facilitating the replacement of the stable connection assembly.

[0022] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] Embodiment 1:

[0024] See also Figure 1-4 A support structure for a precision bearing comprises a bearing support seat 1, a plurality of connecting through holes 2 are formed in a rectangular array on the upper surface of the bearing support seat 1, two stable connecting plates 3 are fixedly connected symmetrically along the center at the top of the back side of the bearing support seat 1, a first hydraulic telescopic rod 4 is detachably mounted on one side of the front side of the stable connecting plate 3, a stable connecting component 5 is arranged inside the bearing support seat 1, two mounting grooves 6 are formed symmetrically along the center at the back side of the stable connecting component 5, and a limiting ring 7 is bonded inside the mounting groove 6;

[0025] There are several connecting through holes 2, and several connecting through holes 2 are equally divided into two groups. The depth of the connecting through holes 2 is greater than the depth of the mounting groove 6. One end of the first hydraulic telescopic rod 4 is adapted to the inside of the limit ring 7. The limit ring 7 is made of a rubber component. There are two limit rings 7. The thickness of the limit ring 7 is less than the depth of the mounting groove 6. The stable connection assembly 5 includes a stable connection ring 51 and a connection base 52. The inside of the stable connection ring 51 is symmetrically fixed with two connection bases 52 along the center. The surface of the stable connection ring 51 is adapted to the inside of the bearing support seat 1. The side wall of the connection base 52 is detachably installed with a second hydraulic telescopic rod 53. One end of the second hydraulic telescopic rod 53 is fixedly connected with an arc-shaped connecting plate 54. The side wall of the arc-shaped connecting plate 54 fits the surface of the precision bearing. The arc-shaped connecting plate 54 is made of a rubber component.

[0026] Benefits: By setting the material of the limiting ring 7 to a rubber component, it is helpful to increase the friction between the limiting ring 7 and the first hydraulic telescopic rod 4, thereby enhancing the stability during connection.

[0027] The working process of the utility model is as follows:

[0028] When the support structure is in use, in order to prevent the precision bearing from loosening, a stable connection component 5 is provided. When the size of the precision bearing to be supported is smaller than the installation size of the bearing support seat 1, the precision bearing to be supported is placed at the center of the two groups of arc-shaped connecting plates 54, and then the second hydraulic telescopic rod 53 is started to extend and retract. Then the second hydraulic telescopic rod 53 will drive the arc-shaped connecting plate 54 to move until the lower surface of the arc-shaped connecting plate 54 is tightly fitted with the surface of the precision bearing, so that the precision bearing can be fixed inside the bearing support seat 1. Because the second hydraulic telescopic rod 53 has the function of automatic extension and retraction, it can control the distance between the two groups of arc-shaped connecting plates 54. Even if the size of the precision bearing to be supported is smaller than the installation size of the bearing support seat 1, it will not cause the precision bearing to loosen, thereby enhancing the practicality of the device.

[0029] In the above scheme, when the support structure is in use, in order to facilitate the replacement of the stable connection component 5, a stable connection plate 3, a first hydraulic telescopic rod 4, a mounting groove 6 and a limit ring 7 are provided. When the stable connection component 5 needs to be replaced, the first hydraulic telescopic rod 4 is started to drive the stable connection component 5 to move until the stable connection component 5 is moved out of the bearing support seat 1, and then the stable connection component 5 is held and a certain external force is applied to the outside to separate the stable connection component 5 from the first hydraulic telescopic rod 4. Because one end of the first hydraulic telescopic rod 4 is clamped in the limit ring 7, it can be directly pulled out, thereby facilitating the replacement of the stable connection component 5.
