Description

Technical Field

[0001] This application relates to the field of molds, and in particular to a high-performance gear reducer angular contact ball bearing assembly mold. Background Technology

[0002] High-performance reducer bearings are angular contact bearings consisting of an inner ring, an outer ring, a cage without locking grooves, and multiple steel balls. They are mainly used to support rotating parts and ensure that the rotating parts can rotate smoothly.

[0003] The existing high-performance reducer bearing assembly method mainly involves the cage being coaxially sleeved on the inner ring, multiple steel balls being sequentially embedded between the cage and the inner ring, and the outer ring being heated and then coaxially pressed onto the cage to form a high-performance reducer bearing.

[0004] However, the cage does not have a locking mechanism, which makes it easy for multiple steel balls to fall out and wear during the process of embedding them. This reduces the assembly quality of the high-performance reducer bearing, reduces the assembly efficiency of the high-performance reducer bearing, prolongs the processing cycle of the high-performance reducer bearing, and thus increases the processing cost of the high-performance reducer bearing. Utility Model Content

[0005] In order to improve the processing cost of high-performance reducer bearings, this application provides an assembly mold for high-performance reducer angular contact ball bearings.

[0006] This application provides a high-performance reducer angular contact ball bearing assembly mold, which adopts the following technical solution:

[0007] A high-performance reducer angular contact ball bearing assembly mold includes a positioning seat, a feeding block, a conveying block, a mold core, and a feeding assembly. The mold core is slidably connected to the positioning seat, and the surface of the mold core is for placing a cage and an inner ring, with the axis of the inner ring coinciding with the axis of the cage. The feeding assembly is connected to the positioning seat. When the mold core approaches the feeding assembly along the positioning seat, the cage and the inner ring face the feeding assembly. The feeding assembly can drive multiple steel balls to be embedded sequentially between the cage and the inner ring. The surface of the conveying block has a limiting cavity for accommodating the ends of the steel balls. When the end of the cage is embedded in the limiting cavity, the outer ring wall of the inner ring and the inner wall of the limiting cavity clamp the two sides of the steel ball to form a limiting. The conveying block clamps the inner ring and the cage on the mold core and places them on the surface of the feeding block. The heated outer ring can be coaxially pressed down and sleeved on the cage located on the feeding block.

[0008] By adopting the above technical solution, during the assembly of high-performance reducer bearings, the inner ring and cage are placed on the surface of the mold core, and the cage is coaxially sleeved on the outer circumference of the inner ring. This drives the mold core to approach the feeding assembly along the positioning seat, with the inner ring and cage facing the feeding assembly. The feeding assembly sequentially embeds multiple steel balls between the cage and the inner ring, achieving automated assembly of multiple steel balls. The transport block approaches the mold core, and the end of the cage is embedded in the limiting cavity. The inner wall of the limiting cavity and the outer circumference of the inner ring clamp the two sides of the steel balls to form a limit, making it difficult for the steel balls to fall off the cage and wear, thus ensuring the assembly quality of the high-performance reducer bearing. The transport block clamps the inner ring and cage on the mold core and places them on the surface of the unloading block. The surface of the unloading block provides support for the cage, allowing the heated outer ring to be coaxially pressed down and sleeved on the outer circumference of the cage located on the unloading block, thus completing the assembly of the high-performance reducer bearing. This improves the assembly efficiency of the high-performance reducer bearing, shortens the processing cycle of the high-performance reducer bearing, and reduces the processing cost of the high-performance reducer bearing.

[0009] Optionally, the positioning seat has a sliding cavity on its surface for the mold core to slide, the bottom wall of the sliding cavity is connected to a positioning screw, the surface of the mold core has a sliding hole for the positioning screw to pass through, and the mold core slides along the axis of the positioning screw on the inner wall of the sliding cavity.

[0010] By adopting the above technical solution, the outer peripheral surface of the mold core abuts against the inner wall of the sliding cavity to form a limit, and one end of the positioning screw is connected to the bottom wall of the sliding cavity, while the other end of the positioning screw passes through the sliding hole. The mold core slides along the axis of the positioning screw on the inner wall of the sliding cavity, making it less likely for the mold core to deviate during the sliding process, thereby improving the stability of the mold core sliding.

[0011] Optionally, the feeding assembly includes a positioning cover plate connected to the surface of the positioning seat. A feeding gap for accommodating steel balls is left between the positioning cover plate and the positioning seat. The feeding gap communicates with the sliding cavity. The outer peripheral surface of the mold core abuts against the inner wall of the sliding cavity and separates the feeding gap and the sliding cavity. When the mold core approaches the feeding gap along the axis of the positioning screw, the inner ring and the retainer on the mold core face the feeding gap. Multiple steel balls in the feeding gap are sequentially embedded between the inner ring and the retainer.

[0012] By adopting the above technical solution, the outer peripheral surface of the mold core abuts against the inner wall of the sliding cavity and separates the feeding gap and the sliding cavity, making it difficult for the steel balls in the feeding gap to enter the sliding cavity, thus improving the limiting stability of the steel balls in the feeding gap. When the inner ring and the cage are placed on the surface of the mold core, and the cage is coaxially sleeved on the outer peripheral surface of the inner ring, the mold core is driven to slide along the inner wall of the sliding cavity towards the feeding gap. The inner ring and the cage face the feeding gap, and multiple steel balls in the feeding gap are sequentially embedded between the inner ring and the cage, realizing the automated assembly of the steel balls without the need for manual assembly by workers, thereby further improving the assembly efficiency of high-performance reducer bearings.

[0013] Optionally, the positioning cover plate has a threaded hole one for screws to pass through, and the positioning seat has a threaded hole two for screws to pass through. The end of the screw can pass through the threaded hole one and be threaded to the inner wall of the threaded hole two.

[0014] By adopting the above technical solution, the screw end passes through a threaded hole and is threaded to the inner wall of the second threaded hole, thereby fixing the positioning cover plate on the positioning seat. The operator rotates the screw according to the height of the inner ring, cage and steel ball to adjust the distance between the positioning cover plate and the positioning seat, so that the size of the feeding gap matches the height of the steel ball, so that the assembly mold can adapt to high-performance reducer bearings of different sizes, thereby improving the versatility of the assembly mold.

[0015] Optionally, the feeding assembly further includes a ball-loading ring. The outer circumferential surface of the positioning seat is provided with a limiting groove for the ball-loading ring to be fitted. The inner wall of the limiting groove abuts against the outer wall of the ball-loading ring to form a limiting. The surface of the ball-loading ring facing the positioning cover plate is provided with a receiving cavity for accommodating steel balls. The receiving cavity is connected to the feeding gap. The bottom wall of the receiving cavity is provided with a guide surface. The guide surface is flared in the direction close to the axis of the positioning seat. The guide surface guides the steel balls in the receiving cavity into the feeding gap.

[0016] By adopting the above technical solution, the ball-loading ring is embedded in the limiting groove, and the outer wall of the ball-loading ring abuts against the inner wall of the limiting groove to form a limit, thereby fixing the ball-loading ring on the positioning seat; at the same time, the feeding gap is connected to the receiving cavity, and the guide surface is flared in the direction close to the axis of the positioning seat. The guide surface guides the steel balls in the receiving cavity into the feeding gap, thereby achieving a stable supply of steel balls in the feeding gap.

[0017] Optionally, the positioning seat is connected to an elastic element, one end of the elastic element in the direction of elastic force is connected to the bottom wall of the sliding cavity, and the other end of the elastic element in the direction of elastic force is connected to the surface of the mold core. The elastic element has the elastic force to drive the mold core to slide away from the positioning seat, and the surface of the mold core abuts against the inner wall of the sliding cavity and separates the feeding gap and the sliding cavity.

[0018] By adopting the above technical solution, when it is necessary to assemble steel balls between the inner ring and the cage on the mold core, pressure is applied to the mold core and it is driven to slide along the inner wall of the sliding cavity towards the direction close to the feeding gap. The inner ring and the cage face the feeding gap, and multiple steel balls in the feeding gap are sequentially embedded between the cage and the inner ring, realizing the automated assembly of the steel balls. When the assembly of multiple steel balls between the inner ring and the cage is completed, the mold core is released, the pressure on the mold core disappears, and the elastic force of the elastic element drives the mold core to slide along the inner wall of the sliding cavity away from the positioning seat. The surface of the mold core presses against the inner wall of the sliding cavity and separates the feeding gap and the sliding cavity, realizing the automated reset of the mold core, thereby improving the ease of use of the assembly mold.

[0019] Optionally, the mold core surface has a positioning cavity one for accommodating the end of the inner ring, and the mold core surface has a positioning cavity two for accommodating the end of the retainer. The positioning cavity one is connected to the positioning cavity two. When the inner ring is embedded in the positioning cavity one and the retainer is embedded in the positioning cavity two, the retainer is coaxially sleeved on the outer circumferential surface of the inner ring.

[0020] By adopting the above technical solution, when the inner ring is embedded in the first positioning cavity and the cage is embedded in the second positioning cavity, the cage is coaxially sleeved on the outer circumferential surface of the inner ring, and the inner wall of the first positioning cavity abuts against the surface of the inner ring to form a limit, and the inner wall of the second positioning cavity abuts against the surface of the cage to form a limit, so that the cage and the inner ring are not easy to shift on the surface of the mold core, thereby improving the limiting stability of the cage and the inner ring on the surface of the mold core.

[0021] Optionally, the surface of the feeding block is provided with a first fixing cavity for accommodating the end of the inner ring, and the surface of the feeding block is provided with a second fixing cavity for accommodating the end of the retainer. When the inner ring is embedded in the first fixing cavity and the retainer is embedded in the second fixing cavity, the retainer is coaxially sleeved on the outer circumferential surface of the inner ring.

[0022] By adopting the above technical solution, when the inner ring and the cage are embedded one-to-one into the fixed cavity one and fixed cavity two, the surface of the inner ring abuts against the inner wall of fixed cavity one to form a limit, and the surface of the cage abuts against the inner wall of fixed cavity two to form a limit. This makes it difficult for the cage and the inner ring to shift on the surface of the feeding block, thereby improving the limiting stability of the cage and the inner ring on the surface of the feeding block. This allows the heated outer ring to be stably pressed down and sleeved on the outer circumference of the cage to form a high-performance reducer bearing, thereby improving the processing quality of the high-performance reducer bearing.

[0023] Optionally, it also includes a die, the surface of which is provided with a fixing groove to accommodate the end of the inner ring. When the die and the die core are closed, the end of the inner ring is embedded in the fixing groove. The inner wall of the fixing groove and the inner wall of the positioning cavity clamp the two sides of the inner ring to form a limit. The die can squeeze the die core along the inner wall of the sliding cavity to approach the feeding gap.

[0024] By adopting the above technical solution, when the end of the inner ring is embedded in the first positioning cavity and the end of the cage is embedded in the second positioning cavity, the die and the mold core are closed, the end of the inner ring is embedded in the fixing groove, and the inner wall of the fixing groove and the inner wall of the first positioning cavity clamp the two sides of the inner ring to form a limit, which further improves the limiting stability of the inner ring and the cage on the surface of the mold core; at the same time, the die provides a force application point to push the mold core to slide in the inner wall of the sliding cavity, which further improves the assembly efficiency of the high-performance reducer bearing.

[0025] Optionally, the positioning cover plate has a relief cavity on the surface opposite to the positioning seat for the transport block to be embedded. The end of the transport block can pass through the relief cavity and be sleeved on the outer ring of the cage. The inner wall of the limiting cavity and the outer circumference of the inner ring clamp the two sides of the steel ball to form a limiting.

[0026] By adopting the above technical solution, the end of the transport block can pass through the clearance cavity and be sleeved on the outer ring of the cage. The inner wall of the limiting cavity and the outer circumference of the inner ring clamp the two sides of the steel ball to form a limit, reducing the wear between the transport block and the positioning seat, thereby extending the service life of the assembly mold.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The arrangement of the positioning seat, feeding block, conveying block, mold core and feeding assembly makes it difficult for the steel balls to fall off the cage and wear, thereby ensuring the assembly quality of the high-performance reducer bearing, realizing the assembly of the high-performance reducer bearing, improving the assembly efficiency of the high-performance reducer bearing, shortening the processing cycle of the high-performance reducer bearing, and thus reducing the processing cost of the high-performance reducer bearing.

[0029] 2. The positioning screws prevent the mold core from shifting during its sliding within the sliding cavity, thus improving the stability of the mold core's sliding.

[0030] 3. The positioning cover plate enables automated assembly of steel balls, eliminating the need for manual assembly and further improving the assembly efficiency of high-performance reducer bearings. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

[0037] This application discloses an assembly mold for a high-performance reducer angular contact ball bearing. (Refer to...) Figure 1 and Figure 2 The high-performance reducer angular contact ball bearing assembly mold includes a positioning seat 1, a feeding block 2, a conveying block 3, a mold core 4, a feeding assembly 5, and a pressing mold 6. The bottom surface of the positioning seat 1 can abut against the ground to form support. The top surface of the positioning seat 1 has a sliding cavity 11 for the mold core 4 to slide. The sliding direction of the mold core 4 is parallel to the height direction of the positioning seat 1. The positioning seat 1 is equipped with a positioning screw 7. The surface of the mold core 4 has a sliding hole 41 for the positioning screw 7 to pass through. The axis of the sliding hole 41 is parallel to the height direction of the positioning seat 1. The end of the positioning screw 7 passes through the sliding hole 41 and is threaded to the bottom wall of the sliding cavity 11. The mold core 4 slides along the axis of the positioning screw 7 on the inner wall of the sliding cavity 11, so that the mold core 4 is not easy to deviate during the sliding process on the inner wall of the sliding cavity 11, thereby improving the stability of the sliding of the mold core 4.

[0038] Reference Figure 1 and Figure 2 The mold core 4 has a positioning cavity 42 on its surface to accommodate the end of the inner ring 16, and a positioning cavity 43 on its surface to accommodate the end of the retainer 8. The positioning cavity 42 is connected to the positioning cavity 43, and the axis of the positioning cavity 42 and the axis of the positioning cavity 43 coincide. When the inner ring 16 is embedded in the positioning cavity 42 and the retainer 8 is embedded in the positioning cavity 43, the retainer 8 is coaxially sleeved on the outer circumferential surface of the inner ring 16. The surface of the inner ring 16 abuts against the inner wall of the positioning cavity 42 to form a limit, and the surface of the retainer 8 abuts against the inner wall of the positioning cavity 43 to form a limit, so that the inner ring 16 and the retainer 8 are not easy to shift on the surface of the mold core 4, thereby improving the positioning stability of the inner ring 16 and the retainer 8 on the surface of the mold core 4.

[0039] Reference Figure 1 and Figure 2 The surface of the die 6 is provided with a fixing groove 61 to accommodate the end of the inner ring 16. When the die 6 and the mold core 4 are closed, one end of the inner ring 16 in the axial direction is embedded in the fixing groove 61, and the other end of the inner ring 16 in the axial direction is embedded in the positioning cavity 42. The inner wall of the positioning cavity 42 and the inner wall of the fixing groove 61 clamp the two sides of the inner ring 16 to form a limit. The die 6 drives the mold core 4 to slide in the inner wall of the sliding cavity 11. The die 6 provides a force application point, thereby improving the stability of the sliding of the mold core 4.

[0040] Reference Figure 1 and Figure 2The feeding assembly 5 is installed on the positioning seat 1. The feeding assembly 5 can sequentially embed multiple steel balls 9 between the inner ring 16 and the cage 8 located on the mold core 4, realizing the automated assembly of the steel balls 9 without manual assembly by the staff, thereby improving the assembly efficiency of high-performance reducer bearings. The feeding assembly 5 includes a positioning cover plate 51 and a ball-loading ring 52. The surface of the positioning cover plate 51 is provided with multiple threaded holes 511 for screws to pass through. The multiple threaded holes 511 are evenly distributed around the axis of the positioning cover plate 51. The axis of the threaded holes 511 is parallel to the axis of the positioning seat 1. The threaded holes 511 penetrate the surface of the positioning cover plate 51 along their own axis. The surface of the positioning seat 1 is provided with multiple threaded holes 12 for screws to pass through. When the positioning cover plate 51 is placed on the top surface of the positioning seat 1, the threaded holes 511 and the threaded holes 12 correspond one-to-one and are connected. The end of the screw passes through the threaded hole 511 and is threaded to the inner wall of the threaded hole 12, realizing the detachable connection of the positioning cover plate 51 on the positioning seat 1.

[0041] Reference Figure 1 and Figure 2 A loading gap 13 is provided between the end faces of the positioning cover plate 51 and the positioning seat 1 to accommodate the steel ball 9. The loading gap 13 is connected to the sliding cavity 11. The size of the loading gap 13 can be changed by rotating the screw to adjust the distance between the positioning cover plate 51 and the positioning seat 1, so that the loading gap 13 can be adapted to the size of the steel ball 9, and the assembly mold can be adapted to high-performance reducer bearings of different sizes, thereby improving the versatility of the assembly mold.

[0042] Reference Figure 1 and Figure 2 The end face of the positioning seat 1 facing the loading gap 13 is provided with a buffer surface 14. The buffer surface 14 is flared in the direction close to the axis of the positioning seat 1. When the mold 6 and the mold core 4 are closed, the mold core 4 is driven to slide along the inner wall of the sliding cavity 11 towards the loading gap 13. The opening of the loading gap 13 faces the inner ring 16 and the retainer 8 on the mold core 4. The buffer surface 14 guides multiple steel balls 9 in the loading gap 13 to be embedded between the inner ring 16 and the retainer 8 in sequence, realizing the automated assembly of the steel balls 9. The outer peripheral surface of the positioning seat 1 is provided with a limiting groove 15 for the ball ring 52 to be fitted. The bottom wall of the ball ring 52 abuts against the limiting groove. The inner wall of 15 forms a limit, realizing the detachable connection of the ball ring 52 on the positioning seat 1. The surface of the ball ring 52 facing the positioning cover plate 51 has a receiving cavity 521 for accommodating the steel ball 9. The receiving cavity 521 is connected to the feeding gap 13, and the bottom wall of the receiving cavity 521 is provided with a guide surface 522. The guide surface 522 is flared in the direction close to the axis of the positioning seat 1. The guide surface 522 can guide the steel ball 9 in the receiving cavity 521 into the feeding gap 13, and impact the steel ball 9 in the feeding gap 13 to be embedded between the inner ring 16 and the cage 8 in sequence, further improving the assembly efficiency of the high-performance reducer bearing.

[0043] Reference Figure 1 and Figure 2 The positioning seat 1 is equipped with an elastic element 10, which can be a compression spring or a tension spring. In this embodiment, the elastic element 10 is a compression spring with a certain deformation capability. One end of the elastic element 10 in the direction of elastic force is connected to the bottom wall of the sliding cavity 11, and the other end of the elastic element 10 in the direction of elastic force is connected to the surface of the mold core 4. The elastic element 10 has the elastic force to drive the mold core 4 to slide away from the feeding gap 13. The surface of the mold core 4 abuts against the inner wall of the sliding cavity 11 and separates the feeding gap 13 and the sliding cavity 11. The nut surface of the positioning screw 7 abuts against the surface of the mold core 4 to form a limiting tendency, thereby realizing the automatic reset of the mold core 4 and improving the ease of use of the assembly mold.

[0044] Reference Figure 3 The surface of the transport block 3 is provided with a limiting cavity 31 for the ball to be embedded. The surface of the positioning cover plate 51 facing away from the positioning seat 1 is provided with a relief cavity 512 for the transport block 3 to pass through. The relief cavity 512 passes through the outer wall of the positioning cover plate 51 along the axis of the positioning seat 1. When the transport block 3 passes through the relief cavity 512 and abuts against the surface of the cage 8, the steel ball 9 between the inner ring 16 and the cage 8 is embedded in the limiting cavity 31. The inner wall of the limiting cavity 31 and the outer circumference of the inner ring 16 clamp the two sides of the steel ball 9 to form a limit, making it difficult for the steel ball 9 to detach from the cage 8, thereby improving the limiting stability of the steel ball 9 between the cage 8 and the inner ring 16.

[0045] Reference Figure 3 and Figure 4 The bottom surface of the feeding block 2 can abut against the ground to form support. The top surface of the feeding block 2 has a fixing cavity 21 for the end of the inner ring 16 to be inserted. The top surface of the feeding block 2 also has a fixing cavity 22 for accommodating the end of the retainer 8. The fixing cavity 21 is connected to the fixing cavity 22, and the axis of the fixing cavity 21 and the axis of the fixing cavity 22 coincide. When the transport block 3 clamps the inner ring 16 and the retainer 8 on the mold core 4 and inserts them into the fixing cavities 21 and 22 respectively, the retainer 8 is coaxially sleeved on the outer circumference of the inner ring 16. The inner ring 16 abuts against the inner wall of the first fixed cavity 21 to form a limit, and the cage 8 abuts against the inner wall of the second fixed cavity 22 to form a limit, so that the inner ring 16 and the cage 8 are not prone to displacement on the surface of the feeding block 2, thereby improving the limiting stability of the inner ring 16 and the cage 8 on the surface of the feeding block 2; at the same time, the feeding block 2 provides support for the inner ring 16 and the cage 8, so that the heated inner ring 16 can be stably and coaxially pressed down onto the outer circumferential surface of the cage 8 located on the feeding block 2, thereby improving the assembly efficiency of the high-performance reducer bearing.

[0046] The implementation principle of the high-performance reducer angular contact ball bearing assembly mold in this application embodiment is as follows: When installing the high-performance reducer bearing, the inner ring 16 is embedded in the positioning cavity 42, and the cage 8 is embedded in the positioning cavity 43. The cage 8 is coaxially sleeved on the outer circumferential surface of the inner ring 16. The mold 6 and the mold core 4 are closed. One end of the inner ring 16 in the axial direction is embedded in the fixing groove 61, and the other end of the inner ring 16 in the axial direction is embedded in the positioning cavity 42, which further improves the limiting stability of the inner ring 16 and the cage 8 on the mold core 4. The mold 6 drives the mold core 4 to overcome the elastic force of the elastic element 10 and move along the inner wall of the sliding cavity 11 towards the inner ring 16. The material slides towards the feeding gap 13, with the opening of the feeding gap 13 facing the retainer 8 and the inner ring 16. The guide surface 522 guides the steel balls 9 in the receiving cavity 521 into the feeding gap 13, and squeezes the steel balls 9 in the feeding gap 13 to be embedded one-to-one between the retainer 8 and the inner ring 16 along the buffer surface 14, realizing the automated assembly of the steel balls 9. The pressure mold 6 stops applying pressure to the mold core 4, and the elastic element 10 drives the mold core 4 to slide away from the feeding gap 13 along the inner wall of the sliding cavity 11. The surface of the mold core 4 presses against the inner wall of the sliding cavity 11 and separates the feeding gap 13 and the sliding cavity 11, while moving... The transport block 3 passes through the clearance cavity 512 and approaches the mold core 4. The surface of the transport block 3 abuts against the surface of the cage 8. The steel ball 9 is embedded in the limiting cavity 31. The inner wall of the limiting cavity 31 and the outer circumferential surface of the inner ring 16 clamp the two sides of the steel ball 9 to form a limit, making it difficult for the steel ball 9 to detach from the cage 8 and wear. This improves the limiting stability of the steel ball 9 between the cage 8 and the inner ring 16, ensuring the assembly quality of the high-performance reducer bearing. At the same time, the transport block 3 clamps the inner ring 16 on the mold core 4 and the cage 8, which are embedded one-to-one in the fixing cavity 21 and the fixing cavity 22. The cage 8 is coaxially sleeved on the outer circumferential surface of the inner ring 16. The inner ring 16 and the cage 8 are positioned against the inner wall of the fixed cavity 21, forming a limiting position. The surface of the cage 8 abuts against the inner wall of the fixed cavity 22, forming a limiting position. This prevents the inner ring 16 and the cage 8 from shifting on the surface of the feeding block 2, improving the limiting stability of the inner ring 16 and the cage 8 on the surface of the feeding block 2. At the same time, the feeding block 2 provides support for the inner ring 16 and the cage 8, enabling the heated inner ring 16 to be stably and coaxially pressed down onto the outer circumferential surface of the cage 8 located on the feeding block 2. This improves the assembly efficiency of the high-performance reducer bearing, shortens the processing cycle of the high-performance reducer bearing, and thus reduces the processing cost of the high-performance reducer bearing.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
