Description

Technical Field

[0001] This utility model belongs to the field of bearing housing processing technology, specifically relating to a lathe machining fixture for a ship-shaped bearing housing. Background Technology

[0002] The ship-shaped bearing housing consists of a central bearing mounting sleeve and flanges on either side of the sleeve. Bearing mounting holes need to be machined within the sleeve for later bearing installation, while the flanges connect and secure the bearing to the mounting portion of the housing. Due to the irregular shape of the ship-shaped bearing housing, lathe machining is not feasible. Therefore, the bearing mounting holes are typically machined using CNC milling machines. Because the bearing mounting holes require high precision, boring is necessary for final finishing to ensure accuracy, resulting in low machining efficiency. Utility Model Content

[0003] This utility model provides a lathe machining fixture for ship-shaped bearing housings, which aims to solve the problem of low machining efficiency when machining bearing mounting holes in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a lathe machining fixture for a ship-shaped bearing housing, comprising:

[0005] Fixed plate;

[0006] A positioning seat is fixedly installed on the fixed plate, and a V-shaped groove is recessed on the side of the positioning seat near the axis of the fixed plate;

[0007] There are two pull rods, which are arranged parallel to each other at intervals, and both pull rods are fixedly installed on the positioning seat;

[0008] A pressure plate is installed between the two tie rods, both of which are slidably disposed on the pressure plate, and the pressure plate and the V-groove are located on opposite sides of the axis of the fixed plate;

[0009] The tightening member is threadedly connected to the pull rod and abuts against the side of the pressure plate away from the V-groove.

[0010] In one possible implementation, a support block is installed on the inner wall of the V-groove, and one side of the support block is provided with a plurality of protruding ribs for abutting against the outside of the bearing mounting sleeve.

[0011] In one possible implementation, the fixing disk has a cylindrical structure, and the length direction of the protruding rib is arranged along the tangent direction of the fixing disk.

[0012] In one possible implementation, both ends of the rib are threaded with push rods, which are used to abut against the outer wall of the bearing mounting sleeve.

[0013] In one possible implementation, two support rods are fixedly installed on the side of the pressure plate near the positioning seat, and the two support rods are used to abut against the wing plate.

[0014] In one possible implementation, the pressure plate is provided with a first U-shaped groove and a second U-shaped groove at both ends, with the opening of the first U-shaped groove located at the end of the pressure plate and the opening of the second U-shaped groove located on one side of the pressure plate.

[0015] In one possible implementation, a positioning pin is provided between the positioning seat and the fixed plate for positioning the positioning seat on the fixed plate, and the number of positioning pins is at least two.

[0016] In one possible implementation, a counterweight is also fixedly installed on the fixed disk, and the counterweight is disposed on both sides of the axis of the fixed disk opposite to the positioning seat.

[0017] The solution shown in this application, compared with the prior art, involves a fixed plate with a positioning seat mounted on it.

The two pull rods are then inserted into the clearance holes or machining holes on the flange, and finally, the pressure plate is mounted on the pull rods. The tightening member pushes the pressure plate to press and fix the bearing mounting sleeve into the V-groove. This fixes the bearing mounting sleeve into the V-groove, and the V-groove allows for positioning of the bearing mounting sleeve.

[0023] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Please refer to the following: Figures 1 to 3 The lathe machining fixture for the ship-shaped bearing housing provided by this utility model will now be described. The lathe machining fixture for the ship-shaped bearing housing includes a fixed plate 1, a positioning seat 2, a tie rod 3, a pressure plate 4, and a tightening member 5. The positioning seat 2 is fixedly installed on the fixed plate 1, and a V-shaped groove is recessed on the side of the positioning seat 2 near the axis of the fixed plate 1; there are two tie rods 3, which are arranged parallel to each other at intervals, and both tie rods 3 are fixedly installed on the positioning seat 2; the pressure plate 4 is installed between the two tie rods 3, and both tie rods 3 are slidably disposed on the pressure plate 4, and the pressure plate 4 and the V-shaped groove are located on both sides of the axis of the fixed plate 1; the tightening member 5 is threadedly connected to the tie rods 3 and abuts against the side of the pressure plate 4 away from the V-shaped groove.

[0025] The lathe machining fixture for the ship-shaped bearing housing provided in this embodiment, compared with the prior art, features a fixed plate 1 on which a positioning seat 2 is mounted. The positioning seat 2 is located on the side of the fixed plate 1 and has a V-groove on the side of the positioning seat 2 closest to the axis of the fixed plate 1. A pull rod 3 is fixedly mounted on the side of the positioning seat 2 with the V-groove, and a tightening member 5 is threaded onto the pull rod 3. There are two pull rods 3; one end of each pull rod 3 is fixedly mounted on the positioning seat 2, and the other end of each pull rod 3 is slidably fitted with a pressure plate 4. The pressure plate 4 is spaced apart from the positioning seat 2 and located on the side of the opening of the V-groove on the positioning seat 2. In this application, when machining the ship-shaped bearing housing, the outer surface of the bearing mounting sleeve on the ship-shaped bearing housing can be pressed against the inner wall of the V-groove. The two pull rods 3 are then inserted into the clearance holes or machining holes on the flange, and finally, the pressure plate 4 is mounted on the pull rods 3. The tightening member 5 pushes the pressure plate 4 to press and fix the bearing mounting sleeve into the V-groove. This allows the bearing mounting sleeve to be fixed inside the V-groove. The V-groove also helps to position the bearing mounting sleeve. Finally, the fixing plate 1 is clamped and fixed onto a CNC lathe, allowing the bearing mounting sleeve to be machined, effectively improving the machining efficiency of the bearing mounting holes.

[0026] Specifically, in this embodiment, when the ship-shaped bearing housing is installed onto the fixed disk 1, the axis of the bearing mounting hole machined on the bearing mounting sleeve coincides with the axis of the fixed disk 1. Furthermore, the bearing mounting sleeve is located between the two tie rods 3.

[0027] In some embodiments, the positioning seat 2 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 A support block 6 is installed on the inner wall of the V-groove. Multiple protruding ribs are provided on one side of the support block 6 to abut against the outer side of the bearing mounting sleeve. Vertical ribs for mounting the support block 6 are fixedly installed on the positioning seat 2, and the support block 6 is fixed to the vertical ribs with bolts. Multiple protruding ribs are provided on the side of the support block 6 away from the vertical ribs. When the bearing mounting sleeve is installed inside the V-groove, the ribs abut against the side wall of the bearing mounting sleeve, allowing the support block 6 to effectively abut against the bearing mounting sleeve. Simultaneously, the multiple ribs are spaced apart to avoid obstructing the lifting platform on the bearing mounting sleeve.

[0028] Specifically, in this embodiment, multiple ribs located on the same support block 6 are arranged in parallel at intervals along the axial direction of the fixed disk 1.

[0029] In some embodiments, the aforementioned fixed disk 1 may be adopted as follows: Figure 1 The structure shown. Participate Figure 1 The fixed disk 1 has a cylindrical structure, and the length direction of the protruding rib is set along the tangent direction of the fixed disk 1. The cross-section of the fixed disk 1 perpendicular to its axis is circular, which facilitates the clamping of the fixed disk 1 onto a CNC lathe. The length direction of the protruding rib is set along the tangent direction of the fixed disk 1, so that when the outer wall of the bearing mounting sleeve abuts against the protruding rib on the two support blocks 6, the outer wall of the bearing mounting sleeve remains tangent to the protruding rib, thereby aligning the axis of the bearing mounting hole machined on the bearing mounting sleeve with the axis of the fixed disk 1.

[0030] In some embodiments, the support block 6 described above can be as follows: Figure 2 The structure shown. See also Figure 2 Both ends of the raised rib are threadedly connected to push rods 61, which abut against the outer wall of the bearing mounting sleeve. Threaded holes for mounting the push rods 61 are provided on the support block 6, and corresponding through holes are provided on the vertical rib of the positioning seat 2. The push rods 61, by abutting against the outer wall of the bearing mounting sleeve, improve the stability of the bearing mounting sleeve. Simultaneously, the position of the bearing mounting sleeve can be adjusted by adjusting the position of the push rods 61 on the two support blocks 6. This allows for fine-tuning of the bearing mounting sleeve's position even when the casting exhibits some deformation.

[0031] Specifically, in this embodiment, when installing the bearing mounting sleeve onto the fixed plate 1, the bearing mounting sleeve can first be pressed against the two support blocks 6, and then the pressure plate 4 is used to press and fix the bearing mounting sleeve between the two support blocks 6. Finally, the push rod 61 is used to press against the outer wall of the bearing mounting sleeve, which can further fix it. When it is necessary to adjust the position of the bearing mounting sleeve later, the pressure plate 4 can be loosened and the position of the push rod 61 on the two support blocks 6 can be adjusted, thereby allowing for fine-tuning of the position of the bearing mounting sleeve.

[0032] In some embodiments, the pressure plate 4 can be adopted as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3 Two support rods 41 are fixedly installed on the side of the pressure plate 4 near the positioning seat 2. These two support rods 41 abut against the wing plate. Two support rods 41 are also fixedly installed on the side of the pressure plate 4, located between the two tie rods 3. The two support rods 41 are located on one side of each tie rod 3. When the tightening member 5 on the tie rod 3 presses the pressure plate 4 towards the positioning seat 2, the support rods 41 on the pressure plate 4 support the wing plate of the ship-shaped bearing seat. The arrangement of the two support rods 41 ensures that both wing plates are subjected to compressive force, thereby improving the stability of the ship-shaped bearing seat during fixing.

[0033] In some embodiments, the pressure plate 4 can be adopted as follows: Figure 3 The structure shown. See also Figure 3 The pressure plate 4 has a first U-shaped groove and a second U-shaped groove at both ends. The opening of the first U-shaped groove is located at the end of the pressure plate 4, and the opening of the second U-shaped groove is located on one side of the pressure plate 4. The openings of the first and second U-shaped grooves at both ends of the pressure plate 4 are perpendicular to each other. When it is necessary to remove or install the bearing seat, the tightening member 5 must be removed from the pull rod 3 before the pressure plate 4 can be removed from the pull rod 3. At the same time, the two pull rods 3 are located inside the first and second U-shaped grooves, respectively. The inner walls of the first and second U-shaped grooves limit the position of the two pull rods 3, which can improve the stability of the position of the pressure plate 4. This allows the pressure plate 4 to be stably pressed onto the bearing seat. During the rotation of the fixed plate 1, the stability of the bearing seat position on the fixed plate 1 is improved.

[0034] In some embodiments, the positioning seat 2 may be adopted as follows: Figure 2 The structure shown. See also Figure 2A positioning pin 7 is provided between the positioning seat 2 and the fixed plate 1 to position the positioning seat 2 on the fixed plate 1. There are at least two positioning pins 7. The positioning seat 2 is fixedly mounted to the side of the fixed plate 1 by bolts, and corresponding pin holes for installing the positioning pins 7 are provided between the positioning seat 2 and the fixed plate 1. The positioning pins 7 can fix the relative position of the positioning seat 2 and the fixed plate 1. After the positioning seat 2 is stable, it can ensure the stability of the bearing housing when placed on the fixed plate 1, thereby reducing the need for alignment and adjustment of the bearing housing position during processing and improving processing efficiency.

[0035] In some embodiments, the aforementioned fixed disk 1 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 A counterweight 8 is also fixedly installed on the fixed plate 1. The counterweight 8 is positioned on both sides of the axis of the fixed plate 1 opposite to the positioning seat 2. The counterweight 8 is fixedly installed on the fixed plate 1 to ensure the dynamic balance of the fixed plate 1 during rotation, thereby improving the stability of the fixed plate 1 during lathe machining and preventing vibration due to unstable dynamic balance, which would affect the machining quality of the bearing mounting holes.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
