Description

Technical Field

[0001] This utility model belongs to the technical field of sliding bearing production equipment, specifically relating to a Babbitt alloy casting tool for sliding bearings. Background Technology

[0002] Babbitt alloy casting for sliding bearings is a process that involves casting molten Babbitt alloy onto the surface of the bearing substrate to form a uniform, dense alloy layer, thereby improving the bearing's wear resistance, anti-galling properties, and load-bearing capacity. This process involves heating the Babbitt alloy to a molten state and precisely casting it onto a pre-treated bearing substrate using a ladle. After cooling, a strong bond is formed. Strict control of alloy temperature, casting speed, and mold design is required during the casting process to ensure a uniform alloy layer thickness and the absence of defects such as porosity and inclusions. This process is widely used in the manufacture of sliding bearings, especially suitable for high-load, low-speed, or frequent start-stop conditions, significantly extending bearing service life.

[0003] In the production process of sliding bearings, Babbitt alloy casting is usually used. During the casting process, a ladle is needed to hold the molten Babbitt alloy. However, when pouring the alloy liquid using a traditional ladle, it mainly relies on manual operation by the operator, which makes it difficult to achieve quantitative pouring each time. This results in poor control of operational precision and affects the casting quality. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figure 1-4 This embodiment of the present invention provides a Babbitt alloy casting fixture for sliding bearings, comprising:

[0027] The support mechanism 100 includes a support frame 101, a ladle 102 rotatably mounted inside the support frame 101, a top frame 103 fixedly mounted on the top of the support frame 101, a driven gear 104 fixedly connected to the ladle 102, a driving gear 105 mounted on the surface of the support frame 101 via a connecting rod bearing and meshing with the driven gear 104, and a handwheel 106 fixedly mounted on the surface of the driving gear 105.

[0028] The angle positioning mechanism 200 includes a positioning component 201 that dampens the rotation of the driven gear 104, and a damping component 202 for adjusting the tilting angle of the ladle 102.

[0029] The positioning component 201 dampens the driven gear 104, preventing it from rotating too fast or suddenly, thereby improving the stability of the ladle 102 during pouring. The damping component 202 positions and adjusts the pouring angle of the ladle 102, solving the problem that traditional ladles 102 cannot achieve a fixed pouring angle, achieving quantitative pouring of alloy liquid, and thus improving the casting efficiency of specific workpieces.

[0030] Specifically, the positioning component 201 includes an arcuate fixing plate 201a fixedly mounted on the surface of the support frame 101, a groove 201b opened inside the arcuate fixing plate 201a, a slider 201c slidably mounted in the inner cavity of the groove 201b, a connecting plate 201d fixedly mounted on the surface of the slider 201c, a plurality of threaded grooves 201e opened on the surface of the arcuate fixing plate 201a, and an elastic element 201f for engaging the driven gear 104.

[0031] Among them, the surface of the arc fixing plate 201a is engraved with angle lines.

[0032] Furthermore, the surface of the connecting plate 201d is provided with two positioning bolts, and the threaded groove 201e is used in conjunction with the positioning bolts.

[0033] The positioning bolt and the threaded groove 201e are used to fix the slider 201c, thereby facilitating the adjustment of the engagement position of the driven gear 104 rotation angle.

[0034] Preferably, the elastic element 201f includes a cylinder 201f-1 fixedly installed at the end of the slider 201c, a spring 201f-2 fixedly installed in the inner cavity of the cylinder 201f-1, and a locking rod 201f-3 fixedly installed on the end face of the spring 201f-2.

[0035] The spring 201f-2 applies a pushing force to the lever 201f-3, ensuring that the end of the lever 201f-3 is always in contact with the surface of the driven gear 104. When the groove on the surface of the driven gear 104 moves to the end of the lever 201f-3, the lever 201f-3 is springed away by the elastic force of the spring 201f-2, causing the end of the lever 201f-3 to engage inside the groove, thus limiting the rotation angle of the driven gear 104.

[0036] Furthermore, the driven gear 104 has a groove on its surface for use with the locking rod 201f-3, and the size of the locking rod 201f-3 is adapted to the size of the groove.

[0037] Specifically, the damping component 202 includes a damper 202a fixedly mounted on the surface of the support frame 101 and a transmission block 202b fixedly mounted on the surface of the driven gear 104 and used in conjunction with the damper 202a.

[0038] The surface of the transmission block 202b is inclined. Through the cooperation between the damper 202a and the transmission block 202b, the driven gear 104 can be prevented from rotating suddenly or at a large angle, thereby improving the casting stability of the ladle 102.

[0039] Furthermore, the damper 202a has a ball groove at its end, and a ball ball 202c is slidably installed in the inner cavity of the ball groove.

[0040] Among them, the ball bearing 202c is used to reduce the friction between the end of the damper 202a and the transmission block 202b, so as to avoid excessive friction and difficulty in driving the driven gear 104 to rotate.

[0041] In use, the operator drives the drive gear 105 to rotate via the handwheel 106. The drive gear 105 drives the driven gear 104 to rotate, and the driven gear 104 then drives the ladle 102 to rotate, causing the ladle 102 to change angle and pour the alloy liquid into the mold.

[0042] When the driven gear 104 rotates, it drives the transmission block 202b to rotate. The inclined surface of the transmission block 202b squeezes the end of the damper 202a, so that the damper 202a plays a damping role on the driven gear 104, preventing the driven gear 104 from rotating too fast or suddenly, and ensuring the stability of the ladle 102 when it is tilted.

[0043] Depending on the different casting workpieces, the tilting angle of the ladle 102 can be set. Loosen the positioning bolts on the connecting plate 201d so that the positioning bolts are disengaged from the inside of the threaded groove 201e. At this time, move the slider 201c and the connecting plate 201d. The slider 201c slides inside the groove 201b. Adjust the position of the slider 201c according to the angle line to determine the angle used for the slot on the driven gear 104 to rotate to the locking rod 201f-3. This angle is the tilting angle of the ladle 102. After determining the position of the slider 201c, install the positioning bolts on the inside of the threaded groove 201e.

[0044] When the ladle 102 is tilted, the driven gear 104 drives the groove on its surface to rotate. When the groove moves to the clamping rod 201f-3, the end of the clamping rod 201f-3 is engaged in the groove under the elastic force of the spring 201f-2. At this time, the ladle 102 can no longer be tilted, thereby adjusting the tilting angle of the ladle 102.

[0045] In summary, the positioning component 201 dampens the driven gear 104, preventing it from rotating too fast or suddenly, thereby improving the stability of the ladle 102 during pouring. The damping component 202 positions and adjusts the pouring angle of the ladle 102, solving the problem that traditional ladles 102 cannot achieve a fixed pouring angle, thus achieving quantitative pouring of alloy liquid and improving the casting efficiency for specific workpieces.
