Description

Technical Field

[0001] This utility model relates to the field of tilting pad bearing technology, specifically a radial tilting pad bearing housing processing structure. Background Technology

[0002] Tilting pad bearings are a type of hydrodynamic sliding bearing, mainly composed of multiple pads that can swing around a fulcrum. They are widely used in high-speed rotating machinery. The tilting pad bearing housing is an important component of the bearing system, mainly serving to support the pads, maintain the stability of the bearing structure, transmit loads, and realize the arrangement of the lubrication system. Because tilting pad bearings have a built-in lubrication system, it is necessary to drill lubrication oil holes in the bearing housing to connect to the external lubrication system and ensure that the lubricating oil can smoothly enter the bearing and form a stable oil film.

[0003] Most existing tilting pad bearing housings consist of two semi-circular rings. When drilling holes on the outer side of the semi-circular rings, the semi-circular rings need to be fixed in order to ensure the accuracy of the drilling. Currently, V-shaped clamps and pressing plates are usually used to fix the semi-circular rings. However, since the inner angle of the V-shaped clamps is fixed, it is difficult to stably fix semi-circular rings of different sizes. Utility Model Content

[0004] The purpose of this invention is to provide a machining structure for a radially tilting pad bearing housing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A radial tilting pad bearing housing processing structure includes a processing table and a drilling mechanism. The top surface of the processing table is provided with a lifting mechanism for positioning and supporting a semi-ring, and the top surface of the processing table is provided with a pressing mechanism for fixing the semi-ring onto the lifting mechanism.

[0007] The lifting mechanism includes a C-shaped frame fixedly connected to the top surface of the processing table. Two symmetrical support blocks are fixedly connected to the top surface of the C-shaped frame. A rotating plate is rotatably connected between the two ends of the support blocks. An adjustment component for adjusting the tilt angle of the rotating plate at the corresponding position is provided on the bottom surface of the rotating plate.

[0008] Furthermore, the bottom surface of the rotating plate is fixedly connected to a rectangular frame, a slider is slidably connected inside the rectangular frame, a fixed seat is fixedly connected to the bottom surface of the slider, and a cross hole is opened through both ends of the top surface of the C-shaped frame. A moving block is slidably connected inside the cross hole, a screw is screwed through the bottom surface of the moving block, and a fixed block that is rotatably connected to the fixed seat at the corresponding position is rotatably connected to the top end of the screw.

[0009] Furthermore, a limiting rod is fixedly connected between the two ends of the inner side of the rectangular frame, which slides through the slider at the corresponding position.

[0010] Furthermore, a handwheel is fixedly connected to the bottom end of the screw.

[0011] Furthermore, the pressing mechanism includes two symmetrical square frames arranged above the processing table. Inside each square frame are two symmetrical clamping members for clamping and fixing the end of the semi-ring. A connecting plate is fixedly connected to one side of each square frame, and a hydraulic cylinder that is slidably connected to the processing table is fixedly connected to the bottom surface of the connecting plate.

[0012] Furthermore, the clamping member includes a backing plate slidably connected inside a square frame at a corresponding position, and a screw rod rotatably connected to the side of the backing plate and screwed through the square frame at the corresponding position.

[0013] Furthermore, the top surface of the processing table has sliding holes through both ends, the bottom end of the hydraulic cylinder is fixedly connected to a connecting block that slides through the corresponding sliding hole, the two opposite sides inside the support housing of the processing table are rotatably connected to a bidirectional lead screw that is screwed through and engaged with the two connecting blocks, a motor is fixedly connected to the side of the support housing of the processing table, and the output end of the motor is fixedly connected to the bidirectional lead screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The tilt angle of the rotating plate at the corresponding position can be adjusted by adjusting the component, so as to change the included angle between the two rotating plates, so that semi-rings of different sizes can be positioned between the two rotating plates. This makes it easier for the pressing mechanism to fix the semi-rings of different sizes between the two rotating plates, so that the drilling mechanism can perform drilling operations on the semi-rings.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 4 In this embodiment of the present invention, a radial tilting pad bearing housing processing structure includes a processing table 1 and a drilling mechanism 2. The drilling mechanism 2 is disposed above the processing table 1 and can move in multiple axes above the processing table 1. The top surface of the processing table 1 is provided with a lifting mechanism 3 for positioning and supporting the semi-ring. The top surface of the processing table 1 is provided with a pressing mechanism 4 for fixing the semi-ring on the lifting mechanism 3. The lifting mechanism 3 includes a C-shaped frame 31 fixedly connected to the top surface of the processing table 1. The top surface of the C-shaped frame 31 is fixedly connected with two symmetrical support blocks 32. A rotating plate 33 is rotatably connected between the two ends of the support blocks 32. The bottom surface of the rotating plate 33 is provided with an adjustment component for adjusting the tilt angle of the rotating plate 33 at the corresponding position.

[0023] First, place the half-ring (one of the tilting pad bearing housings) between the two rotating plates 33 (with both ends of the half-ring facing upwards). Adjust the tilt angle of the two rotating plates 33 using the adjusting assembly so that the rotating plates 33 are tangent to the half-ring. Then, apply downward pressure to the half-ring by driving the pressing mechanism 4, fixing the half-ring between the two rotating plates 33. Next, drive the drilling mechanism 2 and drill holes on the side of the half-ring according to the design requirements (the drilling mechanism 2 can move along multiple axes, and the working principle of the drilling mechanism 2 is existing technology, which will not be elaborated here). This device can adjust the tilt angle of the rotating plates 33 at the corresponding positions by adjusting the adjusting assembly, so as to change the included angle of the two rotating plates 33, so that half-rings of different sizes can be positioned between the two rotating plates 33. This makes it easier for the pressing mechanism 3 to fix the half-rings of different sizes between the two rotating plates 33, so that the drilling mechanism 2 can perform drilling operations on the half-ring.

[0024] Example 1

[0025] like Figure 3 As shown, in this embodiment, a rectangular frame 34 is fixedly connected to the bottom surface of the rotating plate 33, a slider is slidably connected inside the rectangular frame 34, a fixed seat 35 is fixedly connected to the bottom surface of the slider, a cross hole 36 is opened through both ends of the top surface of the C-shaped frame 31, a moving block 37 is slidably connected inside the cross hole 36, a screw 38 is screwed through the bottom surface of the moving block 37, a fixed block 39 is rotatably connected to the top end of the screw 38 and rotatably connected to the fixed seat 35 at the corresponding position, a limiting rod is fixedly connected between the two ends of the inside of the rectangular frame 34 and slides through the slider at the corresponding position, and a handwheel is fixedly connected to the bottom end of the screw 38.

[0026] In this embodiment, the screw 38 can be rotated by rotating the handwheel. Since the screw 38 is screwed into the corresponding moving block 37, the screw 38 can move along the height direction of the bracket 31 while rotating. The up and down movement of the screw 38 can adjust the tilt angle of the rotating plate 33 at the corresponding position so that the pressing mechanism 4 can fix the semi-rings of different sizes between the two rotating plates 33.

[0027] Example 2

[0028] like Figure 4 As shown, in this embodiment, the pressing mechanism 4 includes two symmetrical square frames 41 arranged above the processing table 1. Inside the square frames 41, there are two symmetrical clamping members for clamping and fixing the ends of the semi-rings. A connecting plate 44 is fixedly connected to one side of the square frame 41. A hydraulic cylinder 45 that is slidably connected to the processing table 1 is fixedly connected to the bottom surface of the connecting plate 44. The clamping member includes a backing plate 42 that is slidably connected to the inside of the square frame 41 at the corresponding position. A screw 43 that is rotatably connected to the side of the backing plate 42 and is screwed through the square frame 41 at the corresponding position is rotatably connected to the side of the backing plate 42. Sliding holes 11 are opened through both ends of the top surface of the processing table 1. A connecting block 46 that slides through the sliding hole 11 at the corresponding position is fixedly connected to the bottom end of the hydraulic cylinder 45. A bidirectional lead screw 47 that is screwed through the two connecting blocks 46 is rotatably connected between the two opposite sides inside the support housing of the processing table 1. A motor 48 is fixedly connected to the side of the support housing of the processing table 1. The output end of the motor 48 is fixedly connected to the bidirectional lead screw 47.

[0029] In this embodiment, firstly, based on the size of the semi-ring, the motor 48 drives the bidirectional lead screw 47 to move the two square frames 41 towards each other, so that the two ends of the semi-ring are respectively aligned with the two square frames 41. Then, driven by the two hydraulic cylinders 45, the two square frames 41 are moved down until the square frames 41 cover the two ends of the semi-ring. Then, by rotating the two screws 43 at the same square frame 41, the two abutments 42 at this location clamp the ends of the semi-ring (the length of the abutment 42 is the same as the inner width of the square frame 41), so as to fix the semi-rings of different widths.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
