Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing production fixture technology, and in particular to a double-spherical pressure adjustable self-lubricating spherical bearing fabric application fixture. Background Technology
[0002] Currently, there is a type of double-spherical pressure-adjustable self-lubricating spherical bearing, which has a bearing seat. The front and back surfaces of the bearing seat are respectively formed with a fabric-coated surface (the fabric-coated surface is used to form a frictional fit with other components of the bearing after the self-lubricating cloth is attached). For example, one side forms a concave spherical surface, and the other side forms a convex spherical surface, with the concave and convex spherical surfaces serving as the fabric-coated surfaces. This type of bearing seat design is disclosed in Chinese utility model patent application number CN202422201109.3, entitled "A Double-Oscillating Thrust Floating Spherical Bearing." Both the concave and convex spherical surfaces of the bearing seat need to be covered with self-lubricating cloth. The process of covering the self-lubricating cloth is as follows: First, the self-lubricating cloth needs to be pre-applied to the concave and convex spherical surfaces of the bearing seat. Then, the bearing seat is placed in a baking equipment for baking to dry the self-lubricating cloth. During the drying process, if stable pressure is not applied to various parts of the self-lubricating cloth, it is difficult to ensure the flatness of the self-lubricating cloth after drying. Therefore, a cloth-applying fixture is needed to apply stable pressure to the self-lubricating cloth on the front and back surfaces of the bearing seat during the baking process to ensure the bonding quality of the self-lubricating cloth. Utility Model Content
[0003] The purpose of this invention is to provide a double-spherical pressure adjustable self-lubricating joint bearing cloth application tool. The technical problem to be solved is how to stably apply pressure to the lubricating cloth on the front and back cloth application surfaces of the bearing seat.
[0004] To achieve the above objectives, the solution of this utility model is: a double-spherical pressure adjustable self-lubricating spherical bearing patching tool, including a first mold, a second mold and a fastening mechanism;
[0005] The first mold and the second mold are used for inserting a shaft seat. A first cloth surface is formed on the front of the shaft seat, and a first lubricating cloth is attached to the first cloth surface. A second cloth surface is formed on the back of the shaft seat, and a second lubricating cloth is attached to the second cloth surface. The first mold is located on the side where the first cloth surface is located, and a first pressing part is formed on the first cloth surface. The second mold is located on the side where the second cloth surface is located, and a second pressing part is formed on the second cloth surface.
[0006] The fastening mechanism is used to connect between the first mold and the second mold, and to drive the first mold and the second mold closer together and lock them, so that after locking, the first pressing part presses the first lubricating cloth onto the first patch surface, and the second pressing part presses the second lubricating cloth onto the second patch surface.
[0007] Furthermore, the first patch surface is a concave spherical surface, the first pressing part is a convex spherical surface, and the convex spherical shape of the first pressing part allows it to adhere to the side of the first lubricating cloth facing the first pressing part when pressed against the first lubricating cloth.
[0008] Furthermore, the second adhesive surface is a convex spherical surface, and the second pressing part is a concave spherical surface. The concave spherical shape of the second pressing part allows it to adhere to the side of the second lubricating cloth facing the second pressing part when pressed against the second lubricating cloth.
[0009] Furthermore, it also includes an elastic element, which is disposed on the side of the second mold facing the first mold. When the shaft seat is placed between the first mold and the second mold, the elastic element is used to abut against the shaft seat and elastically push the shaft seat toward the first mold.
[0010] Furthermore, multiple elastic elements are provided, and the multiple elastic elements are evenly distributed around the second pressing part.
[0011] Furthermore, the elastic element is a compression spring.
[0012] Furthermore, the fastening mechanism includes a bolt and a nut. One end of the bolt is radially expanded outward to form a bolt head, and the other end forms a bolt tail. The first mold and the second mold are respectively provided with bolt through holes. The bolt tail is used to pass through the bolt through holes on the first mold and the second mold in sequence, and then form a threaded connection with the nut to clamp and lock the first mold and the second mold between the bolt head and the nut.
[0013] Furthermore, multiple bolts are provided, and the number of nuts corresponds to the number of bolts. Multiple bolt holes are evenly distributed around the edges of both the first mold and the second mold. The multiple bolt holes on the first mold can be aligned with the multiple bolt holes on the second mold, so that the first mold and the second mold can be clamped and locked respectively by multiple bolt heads and nuts.
[0014] Furthermore, the first mold, the second mold, and the fastening mechanism are made of metal.
[0015] After adopting the above solution, the beneficial effects of this utility model are as follows:
[0016] (1) By placing the shaft seat between the first mold and the second mold, the first mold is located on the side where the first cloth surface of the shaft seat is located, and the second mold is located on the side where the second cloth surface of the shaft seat is located. Since the first mold has a first pressing part facing the first cloth surface, and the second mold has a second pressing part facing the second cloth surface, after the fastening mechanism drives the first mold and the second mold to approach and lock, the first pressing part can press the first lubricating cloth on the first cloth surface, and the second pressing part can press the second lubricating cloth on the second cloth surface. Thus, during the baking process, the lubricating cloth on the front and back cloth surfaces of the shaft seat can be stably pressed to avoid deformation and wrinkles of the lubricating cloth after baking.
[0017] (2) In the scheme that also includes an elastic element, the elastic element is disposed on the side of the second mold facing the first mold, and when the shaft seat is placed between the first mold and the second mold, the elastic element is used to abut against the shaft seat and elastically push the shaft seat towards the first mold. By pushing the shaft seat with the elastic element, the pressure on the second patch surface can be reduced and the pressure on the first patch surface can be increased. In addition, combined with the different clamping forces of the fastening mechanism, the pressure on the first patch surface and the second patch surface can be distributed.

Detailed Implementation
[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] Embodiments of the invention will now be described in full with reference to the accompanying drawings. It should be noted that the invention may be implemented in various forms and is not limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0026] The double-spherical pressure adjustable self-lubricating spherical bearing has a bearing seat 4, which has a front and a back surface. The front surface of the bearing seat 4 forms a first fabric-coated surface 5, and the back surface of the bearing seat 4 forms a second fabric-coated surface 7. During the manufacturing process, a first lubricating cloth 6 needs to be pre-coated on the first fabric-coated surface 5, and a second lubricating cloth 8 needs to be pre-coated on the second fabric-coated surface 7. Then the bearing seat 4 is baked so that after baking, the first lubricating cloth 6 is stably adhered to the first fabric-coated surface 5, and the second lubricating cloth 8 is stably adhered to the second fabric-coated surface 7.
[0027] This utility model provides a double-spherical pressure adjustable self-lubricating spherical bearing fabric application fixture, combined with... Figure 1-5 As shown, it includes a first mold 1, a second mold 2, and a fastening mechanism 3, all preferably made of metal to withstand high temperatures. The first mold 1 and the second mold 2 are used to accommodate the shaft seat 4. The first mold 1 is located on the side where the first fabric surface 5 is located, and the first mold 1 has a first pressing part 9 facing the first fabric surface 5. The second mold 2 is located on the side where the second fabric surface 7 is located, and the second mold 2 has a second pressing part 10 facing the second fabric surface 7. The fastening mechanism 3 can be any existing structure that can clamp the two parts. It is used to connect the first mold 1 and the second mold 2 so that the first mold 1 and the second mold 2 can be brought closer and locked. After locking, the first pressing part 9 presses the first lubricating cloth 6 on the first fabric surface 5, and the second pressing part 10 presses the second lubricating cloth 8 on the second fabric surface 7. This enables stable pressure to be applied to the lubricating cloths on the front and back fabric surfaces of the shaft seat during the baking process.
[0028] Specifically, in this embodiment, the first adhesive surface 5 is a concave spherical surface, and the first pressing part 9 is a convex spherical surface. The convex spherical shape of the first pressing part 9 allows it to adhere to all parts of the first lubricating cloth 6 facing the first pressing part 9 when pressed against the first lubricating cloth 6. More specifically, the curvature of the convex spherical surface of the first pressing part 9 matches the curvature of the corresponding position of the concave spherical surface of the first adhesive surface 5. Similarly, the second adhesive surface 7 is a convex spherical surface, and the second pressing part 10 is a concave spherical surface. The concave spherical shape of the second pressing part 10 allows it to adhere to all parts of the second lubricating cloth 8 facing the second pressing part 10 when pressed against the second lubricating cloth 8. More specifically, the curvature of the concave spherical surface of the second pressing part 10 matches the curvature of the corresponding position of the convex spherical surface of the second adhesive surface 7.
[0029] It also includes an elastic element 11, which is disposed on the side of the second mold 2 facing the first mold 1. Preferably, the elastic element 11 is a compression spring, but other elastic structures can also be used, without limitation. When the bearing seat 4 is placed between the first mold 1 and the second mold 2, the elastic element 11 abuts against the bearing seat 4, elastically pushing the bearing seat 4 towards the first mold 1, thereby reducing the pressure on the second fabric surface and increasing the pressure on the first fabric surface. Furthermore, combined with the different clamping forces of the fastening mechanism, the pressure on the first and second fabric surfaces is distributed. Preferably, multiple elastic elements 11 are provided, and the multiple elastic elements 11 are evenly distributed around the second pressing part 10 to achieve stable pressure application.
[0030] Specifically, in this embodiment, the fastening mechanism 3 includes bolts 12 and nuts 13. One end of the bolt 12 is radially expanded outward to form a bolt head 14, and the other end forms a bolt tail 15. Bolt holes 16 are respectively provided on the first mold 1 and the second mold 2. The bolt tail 15 is used to sequentially pass through the bolt holes 16 on the first mold 1 and the second mold 2, and then forms a threaded connection with the nut 13 to clamp and lock the first mold 1 and the second mold 2 between the bolt head 14 and the nut 13. Multiple bolts 12 are provided, and the number of nuts 13 corresponds to the number of bolts 12. Multiple bolt holes 16 are evenly distributed around the edges of both the first mold 1 and the second mold 2. The multiple bolt holes 16 on the first mold 1 can be aligned with the multiple bolt holes 16 on the second mold 2, so that the first mold 1 and the second mold 2 can be clamped and locked respectively by the multiple bolt heads 14 and nuts 13, making it easier to adjust the pressure at each position to achieve stable pressure application.
