Description
Technical Field
[0001] This utility model relates to the field of bearing housing positioning technology, and in particular to a positioning mold device for combined bearing housing forging. Background Technology
[0002] The bearing housing is an important component connecting the bearing to the machine base. Its main function is to support the rotating shaft, bear axial and radial loads, and lubricate the bearing with internal lubricating oil to reduce friction and wear, ensuring the long-term stable operation of the bearing.
[0003] A search of Chinese utility model patent CN217370272U reveals a tooling for forging wind turbine bearing seat blanks. The tooling includes a forging base, a forging equipment platform on the forging base, a forging equipment body on the forging equipment platform, and a control and display device on the forging equipment platform. The forging base has an adjustment cavity containing a power mechanism. In this utility model, during the forging operation of the wind turbine bearing seat blank, a rotary motor drives a rotating disk, which in turn drives three convex sliding rods to slide. The movement of the three convex sliding rods respectively drives three arc-shaped clamping blocks to move, thus clamping the placed bearing seat blank. This clamping in three directions ensures stable clamping of the bearing seat blank, preventing displacement. The arc-shaped anti-slip rubber also provides excellent anti-slip properties, preventing relative slippage after placement.
[0004] However, the bearing housing includes a pin seat and an inner ring structure, and is not a complete circular structure. The patented method of using three arc-shaped clamping blocks cannot accurately clamp and position the bearing housing, which can easily cause the bearing housing to shift. In view of this, this application proposes a combined positioning mold device for forging bearing housing to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a combined positioning mold device for forging bearing seats.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A combined positioning mold device for forging bearing housings includes a worktable, a bearing housing body, a positioning plate, and a clamping block. The bearing housing body includes a pin seat and an inner ring. The bearing housing body is positioned above the worktable. The positioning plate is positioned on one side of the pin seat, and the clamping block is positioned on one side of the inner ring. The clamping block has a V-groove, and a fixing block is positioned on the other side of the clamping block. The worktable has a positioning hole. Both the fixing block and the positioning plate have fixing components. The fixing block and the positioning plate are fixedly connected to the worktable through the fixing components. A threaded rod is rotatably installed inside the fixing block, and the threaded rod is threadedly connected to the clamping block.
[0008] Furthermore, the positioning holes are arranged in a ring array on the surface of the worktable.
[0009] Furthermore, the fixing component includes a screw and a nut, and both the positioning plate and the positioning block are provided with through holes. The screw passes through the through hole and the positioning hole, and the nut is screwed on the upper and lower ends of the screw.
[0010] Furthermore, an extension plate is provided at the bottom end of the positioning plate, and the extension plate is disposed on the lower surface of the pin seat.
[0011] Furthermore, two symmetrical guide strips are welded to one side of the fixing block, and guide grooves matching the guide strips are opened on both sides of the clamping block.
[0012] Furthermore, one end of the threaded rod is provided with an internal hexagonal hole, and an internal hexagonal wrench is provided in the internal hexagonal hole.
[0013] Furthermore, a collection box is provided directly below the positioning hole.
[0014] Furthermore, an alignment post is fixedly installed on the upper surface of the worktable.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. This utility model uses a positioning plate, clamping block, fixing block, and threaded rod to position the inner ring of the bearing housing body on the front side of the workbench. Then, an Allen wrench is inserted into the Allen hole and rotated. The Allen wrench drives the threaded rod to rotate, and the rotation of the threaded rod drives the clamping block to move closer to the bearing housing body. The V-groove squeezes the inner ring, causing the bearing housing body to move to the center position. During the movement of the bearing housing body, the pin seat is limited by the positioning plate, and both the inner ring and the pin seat can be well positioned.
[0017] 2. This utility model uses positioning holes to allow the screw to pass through the through hole and the positioning hole, and then the nut to be tightened. This allows the positioning plate and the fixing block to be fixedly installed. The annularly distributed positioning holes allow the positioning plate and the fixing block to be installed in different positions, as long as their center lines are on the same straight line. This is beneficial for the bearing housing body to perform loading / unloading work in different directions, and can also serve as a dust removal channel. After forging, the iron oxide scale on the workbench is swept away with a brush and falls into the collection box through the positioning holes for collection.
[0018] 3. By setting an extension plate, this utility model compensates for the height difference since the inner ring is usually thicker than the pin seat, effectively avoiding the problem of uneven force caused by uneven placement of the bearing housing body during forging.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Reference Figure 1-3 , Figure 5-7 A combined positioning mold device for forging bearing housings includes a worktable 1, a bearing housing body 2, a positioning plate 3, and a clamping block 4. The bearing housing body 2 includes a pin seat 5 and an inner ring 6. The bearing housing body 2 is positioned above the worktable 1. The positioning plate 3 is positioned on one side of the pin seat 5, and the clamping block 4 is positioned on one side of the inner ring 6. The clamping block 4 has a V-groove 7, and a fixing block 8 is positioned on the other side of the clamping block 4. The worktable 1 has positioning holes 9, and both the fixing block 8 and the positioning plate 3 have fixing components. The fixing block 8 and the positioning plate 3 are fixedly connected to the workbench 1 through a fixing assembly. A threaded rod 10 is rotatably installed inside the fixing block 8. The threaded rod 10 is threadedly connected to the clamping block 4, which positions the inner ring 6 of the bearing seat body 2 at the front of the workbench 1. The rotation of the threaded rod 10 drives the clamping block 4 to move closer to the bearing seat body 2. The inner ring 6 is squeezed by the V-groove 7, causing the bearing seat body 2 to move to the center position. During the movement of the bearing seat body 2, the pin seat 5 is limited by the positioning plate 3, and both the inner ring 6 and the pin seat 5 can be well positioned.
[0029] Reference Figure 3-4 Specifically: the positioning holes 9 are arranged in a ring array on the upper surface of the workbench 1. The ring-shaped positioning holes 9 allow the positioning plate 3 and the fixing block 8 to be installed in different positions, as long as their center lines are on the same straight line. This is beneficial for the bearing seat body 2 to perform loading / unloading operations in different directions.
[0030] Reference Figure 2 , Figure 6 Specifically: the fixing component includes a screw 11 and a nut 12. Both the positioning plate 3 and the positioning block are provided with through holes 13. The screw 11 passes through the through hole 13 and the positioning hole 9. The nut 12 is screwed on the upper and lower ends of the screw 11. The screw 11 is passed through the through hole 13 and the positioning hole 9, and then the nut 12 is tightened. In this way, the positioning plate 3 and the fixing block 8 can be fixedly installed.
[0031] Reference Figure 2 , Figure 6 Specifically: the bottom end of the positioning plate 3 is provided with an extension plate 14, which is located on the lower surface of the pin seat 5; the pin seat 5 is placed on the extension plate 14. Since the inner ring 6 is usually thicker than the pin seat 5, the extension plate 14 compensates for this height difference, effectively avoiding the problem of uneven force caused by uneven placement of the bearing seat body 2 during forging.
[0032] Reference Figure 5 Specifically: two symmetrical guide strips 15 are welded to one side of the fixing block 8, and guide grooves 16 matching the guide strips 15 are opened on both sides of the clamping block 4. The guide strips 15 and guide grooves 16 play a guiding and supporting role in the movement of the clamping block 4, thereby improving the accuracy of the movement.
[0033] Reference Figure 5 Specifically: One end of the threaded rod 10 is provided with an internal hexagonal hole 17, and an internal hexagonal wrench 18 is provided in the internal hexagonal hole 17. When the internal hexagonal wrench 18 is inserted into the internal hexagonal hole 17 and rotated, the internal hexagonal wrench 18 drives the threaded rod 10 to rotate.
[0034] Reference Figure 1 Specifically: A collection box 19 is provided directly below the positioning hole 9. After forging, the iron oxide scale on the workbench 1 is swept away with a brush and falls into the collection box 19 through the positioning hole 9 for collection.
[0035] Reference Figure 3 Specifically: an alignment post 20 is fixedly installed on the upper surface of the workbench 1, and the bearing seat body 2 is initially positioned by placing the inner ring 6 outside the alignment post 20.
[0036] Working principle: The screw 11 is passed through the through hole 13 and the positioning hole 9, and then the nut 12 is tightened. This securely installs the positioning plate 3 and the fixing block 8. The annularly distributed positioning holes 9 allow the positioning plate 3 and the fixing block 8 to be installed in different positions, as long as their center lines are aligned. This facilitates loading / unloading of the bearing housing body 2 in different directions. The inner ring 6 of the bearing housing body 2 is positioned in front of the worktable 1, and the bearing housing body 2 is initially positioned by placing the inner ring 6 outside the alignment post 20. At this time, the pin seat 5 is placed on the extension plate 14. Since the inner ring 6 is usually thicker than the pin seat 5, the extension plate 14 compensates for this height difference, effectively preventing bearing... The uneven placement of the bearing seat body 2 during forging caused uneven stress. Next, an internal hex wrench 18 was inserted into the internal hex hole 17 and rotated. The internal hex wrench 18 caused the threaded rod 10 to rotate, which in turn drove the clamping block 4 closer to the bearing seat body 2. The V-groove 7 squeezed the inner ring 6, causing the bearing seat body 2 to move to the center position. During the movement of the bearing seat body 2, the pin seat 5 was limited by the positioning plate 3, while the guide bar 15 and guide groove 16 provided guidance and support for the movement of the clamping block 4, improving the accuracy of the movement. After forging, the iron oxide scale on the workbench 1 was cleaned with a brush and fell through the positioning hole 9 into the collection box 19 for collection.
