Description

Technical Field

[0001] This utility model relates to the field of tapered roller bearing polishing technology, specifically to a polishing equipment for the production of tapered roller bearings. Background Technology

[0002] Tapered roller bearings are separable bearings, with both the inner and outer rings having tapered raceways. These bearings are classified into different structural types, such as single-row, double-row, and four-row tapered roller bearings, according to the number of rows of rollers. During the production process of tapered roller bearings, the outer ring needs to be polished to eliminate minor imperfections, burrs, and oxide layers on the outer ring surface, making the surface smoother and flatter, reducing frictional resistance, and improving the stability and service life of the bearing during operation.

[0003] When polishing tapered roller bearings, because the outer ring of the tapered roller bearing is circular, it is difficult to form a stable fixation on the outer ring of the tapered roller bearings in batches. Therefore, it is often necessary for workers to hold the outer ring of the tapered roller bearing by hand and polish it one by one. This operation is inefficient and the workload of the workers is heavy.

[0004] In summary, existing tapered roller bearings suffer from problems such as difficulty in batching and fixing during polishing, low polishing efficiency, and a heavy workload for operators. Utility Model Content

[0005] The purpose of this invention is to provide a polishing equipment for the production of tapered roller bearings, so as to solve the technical problems that most existing tapered roller bearings are difficult to batch and fix during polishing, resulting in low polishing efficiency and a heavy workload for operators.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0009] The feeding assembly includes a multi-stage cylinder at one end of the feeding frame, a support rod at the output end of the multi-stage cylinder, with a threaded end of the support rod near the multi-stage cylinder, a threaded sleeve on the threaded end of the support rod, the threaded sleeve being threadedly connected to the support rod, a traction seat rotatably located at one end of the threaded sleeve, the traction seat being slidably sleeved on the outside of the support rod, several sets of expansion rods symmetrically distributed movably on the outside of the support rod, an inner wall support rod movably located at one end of the expansion rod, a three-piece assembly movably located in the middle of the expansion rod, a connecting rod movably located between the three-piece assemblies, and traction rods symmetrically distributed on one side of the traction seat, with the traction rods rotatably connected to one end of a set of three-piece assemblies to form traction on the connecting rods.

[0010] As a further embodiment of this utility model: the top of the feeding rack forms a V-shaped feeding trough through a partition, and the lowest point of the V-shaped feeding trough is located directly below the support rod.

[0011] As a further embodiment of this utility model: the top of the unloading rack forms a V-shaped unloading groove through the second partition, and the lowest point of the V-shaped unloading groove is located on one side of the lowest point of the V-shaped loading groove.

[0012] As a further embodiment of this utility model: a material feeding groove is provided at one end of the feeding rack and the unloading rack that are close to each other, and a limiting groove is provided on the other side of the traction seat. A limiting ring connected to the threaded sleeve is slidably arranged inside the limiting groove.

[0013] As a further embodiment of this utility model: the polishing assembly includes a guide rail seat disposed on the top of the polishing table, transverse sliding seats symmetrically distributed inside the guide rail seat, and a bidirectional lead screw disposed inside the guide rail seat for driving the transverse sliding seats to move, wherein the bidirectional lead screw and the transverse sliding seats are threadedly connected.

[0014] As a further embodiment of this utility model: a motor is provided on the top of the transverse moving seat, a polishing wheel is provided at the output end of the motor, and a protective cover for protecting the polishing wheel is provided on the motor.

[0015] As a further embodiment of this utility model: the top of the polishing table is symmetrically provided with a support frame, and the support frame is located at both ends of the first motor. The top of the support frame is threadedly connected with a lifting screw, and the bottom end of the lifting screw is provided with a fixing frame. Grinding wheels are rotatably provided at the bottom of the support frame and inside the fixing frame. The second motor is provided on one side of the support frame.

[0016] As a further embodiment of this utility model: the feeding assembly includes a support shaft symmetrically arranged on the top of a set of partitions, a side plate arranged on the top of the support shaft, and the side plate is located on both sides of the support frame.

[0017] As a further embodiment of this utility model: a plurality of electric telescopic shafts are provided on the side of the side plates that are close to each other, and a clamping plate is provided at the end of the electric telescopic shafts that are close to each other.

[0019] The beneficial effects of this utility model are:

[0020] 1. In this utility model, the V-shaped structure of the V-shaped feeding groove allows for the batch placement of tapered roller bearing outer rings, ensuring that the center points of multiple sets of tapered roller bearing outer rings are on the same axis. This facilitates the subsequent connection of the mounting rod and the inner wall support rod. By rotating the threaded sleeve and utilizing the linkage between the traction seat and the traction rod, the three-piece linkage and the connecting rod move, thereby opening the expansion rod and supporting the inner wall of the bearing. This allows for the rapid fixing of a batch of tapered roller bearing outer rings, further improving the automation and efficiency of feeding, ensuring stability during subsequent polishing, and reducing the operational burden on workers.

[0021] 2. In this utility model, during material feeding, the electric telescopic shaft drives the clamping plate to clamp the outer ring of the bearing. The traction seat resets so that the inner wall support rod no longer supports the inner wall of the outer ring of the bearing. At this time, the support rod and the clamping plate are retracted, and the outer ring of the bearing falls into the V-shaped feeding groove for easy collection. During the movement, the outer ring of the bearing will come into contact with the buffer plate. At this time, the energy-absorbing spring and the buffer airbag play a buffering role, which greatly reduces the impact force on the bearing, avoids damage to the bearing during the feeding process, and improves the yield of bearings.

[0029] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0030] like Figure 1-5 As shown, a polishing device for producing tapered roller bearings.

[0031] It includes a feeding rack 1, a polishing table 2 and a unloading rack 3 arranged in sequence, with a feeding component on the feeding rack 1, a polishing component on the polishing table 2 and an unloading component on the unloading rack 3;

[0032] The feeding assembly includes a multi-stage cylinder 7 disposed at one end of the feeding frame 1, a support rod 8 disposed at the output end of the multi-stage cylinder 7, and a threaded end of the support rod 8 near the multi-stage cylinder 7. A threaded sleeve 9 is disposed on the threaded end of the support rod 8 and is threadedly connected to the support rod 8. A traction seat 10 is rotatably disposed at one end of the threaded sleeve 9 and is slidably sleeved on the outside of the support rod 8. A limit groove 11 is provided on the other side of the traction seat 10. The internal sliding part of the support rod 1 has a limiting ring 12 connected to the threaded sleeve 9. Several sets of expansion rods 13 are symmetrically distributed on the outside of the support rod 8. An inner wall support rod 14 is movably disposed at one end of the expansion rod 13. A three-piece joint 15 is movably disposed in the middle of the expansion rod 13. A connecting rod 16 is movably disposed between the three-piece joints 15. A traction rod 17 is symmetrically distributed on one side of the traction seat 10, and the traction rod 17 is rotatably connected to one end of a set of three-piece joints 15 to form a connection with the connecting rod 16. The top of the feeding rack 1 is connected to a V-shaped feeding groove formed by a partition 4, with the lowest point of the V-shaped feeding groove located directly below the support rod 8. When feeding the outer ring of the tapered roller bearing, multiple sets of tapered roller bearings are placed in the V-shaped feeding groove of the feeding rack 1. The multi-stage cylinder 7 is activated, providing power to move the support rod 8. The support rod 8 and the inner wall support rod 14 are inserted into the interior of the outer ring of the tapered roller bearing. Then, the threaded sleeve 9 is rotated, and the limiting ring 12 and the limiting slide groove are engaged. Under the transition structure formed by 11, the traction seat 10 moves and slides accordingly. Through the linkage of the traction seat 10, traction rod 17, three-piece linkage 15 and series rod 16, the expansion rod 13 opens, and the inner wall support rod 14 supports the inner wall of the outer ring of the bearing, realizing fast and stable feeding, improving feeding efficiency and accuracy, and ensuring the stability of the feeding and polishing process. It should be noted that the length of the support rod 8 should not be too long to avoid deformation of the support rod 8 caused by placing too many tapered roller bearing outer rings.

[0033] In this embodiment, specifically, the feeding rack 1 and the unloading rack 3 are both provided with a material conveying groove 6 at their respective ends, providing a channel for conveying the bearing outer ring, so that the bearing outer ring can be smoothly conveyed from the feeding rack 1 to the polishing table 2, and then from the polishing table 2 to the unloading rack 3, ensuring the continuity of the production process.

[0034] In this embodiment, the polishing assembly specifically includes a guide rail seat 18 disposed on the top of the polishing table 2, symmetrically distributed transverse seats 19 slidably disposed inside the guide rail seat 18, and a bidirectional lead screw 20 rotatably disposed inside the guide rail seat 18 for driving the transverse seats 19 to move. The bidirectional lead screw 20 and the transverse seats 19 are threadedly connected. A motor 21 is disposed on the top of the transverse seats 19, and a polishing wheel 22 is disposed at the output end of the motor 21. A protective cover 23 for protecting the polishing wheel 22 is disposed on the motor 21. A support frame 24 is symmetrically disposed on the top of the polishing table 2, and the support frame 24 is located at both ends of the motor 21. A lifting screw 25 is threadedly connected to the top of the support frame 24, and a fixing frame 26 is disposed at the bottom end of the lifting screw 25. Grinding wheels 27 are rotatably disposed at the bottom of the support frame 24 and inside the fixing frame 26. A second motor 28 is disposed on one side of the support frame 24. The guide rail 18 provides a track for the movement of the transverse sliding seat 19, which moves under the drive of the bidirectional lead screw 20, thereby adjusting the position of the polishing wheel 22. This can be adjusted according to the size of the bearing outer ring, improving the flexibility and comprehensiveness of polishing. The motor 21 provides power to the polishing wheel 22, which polishes the bearing, removing burrs and defects from the bearing surface and improving the surface quality of the bearing. The protective cover 23 prevents debris and dust from splashing during the polishing process. The support frame 24 provides support for the grinding wheel 27 set on the lifting screw 25. The lifting screw 25 can adjust the height of the fixed frame 26, thereby adjusting the height of the top-mounted grinding wheel 27. The symmetrically distributed grinding wheels 27 can polish the edge of the bearing, improving the edge quality of the bearing. The motor 28 provides power to the grinding wheel 27, driving the bottom grinding wheel 27 to rotate.

[0035] In this embodiment, specifically, the top of the unloading rack 3 forms a V-shaped unloading groove through the partition 2 5, and the lowest point of the V-shaped unloading groove is located on one side of the lowest point of the V-shaped loading groove. The unloading assembly includes a support shaft 29 symmetrically arranged on the top of a set of partition 2 5, a side plate 30 arranged on the top of the support shaft 29, and the side plate 30 is located on both sides of the support frame 24. Several sets of electric telescopic shafts 31 are arranged on the side of the side plates 30 that are close to each other, and a clamping plate 32 is arranged at the end of the electric telescopic shafts 31 that are close to each other. Several sets of energy-absorbing springs 33 are arranged on one side of another set of partition 2 5, and a buffer plate 34 is arranged at one end of the energy-absorbing springs 33. Several sets of buffer airbags 35 connected to the buffer plate 34 are also arranged on the side of another set of partition 2 5 where the energy-absorbing springs 33 are arranged, and the buffer airbags 35 are provided with air holes. The polished bearing outer ring is conveyed to the top of the unloading rack 3. At this time, the electric telescopic shaft 31 is activated, driving the clamping plate 32 to clamp the outer ring of the bearing. Then, the operator resets the threaded sleeve 9 and the traction seat 10, and the expansion rod 13 is retracted. The inner wall support rod 14 no longer supports the inner wall of the outer ring of the bearing. Then, the multi-stage cylinder 7 is used to retract the support rod 8. After the retraction is completed, the electric telescopic shaft 31 also drives the clamping plate 32 to retract. As a result, the outer ring of the bearing falls into the V-shaped feeding groove. During the movement, the outer ring of the bearing will come into contact with the buffer plate 34. At this time, the energy-absorbing spring 33 and the buffer airbag 35 play a buffering role. During the compression and recovery deformation process of the buffer airbag 35, it can pull the energy-absorbing spring 33 to avoid excessive vibration of the energy-absorbing spring 33. This greatly reduces the impact force on the bearing, avoids damage to the bearing during the feeding process, and improves the bearing yield. Rubber pads can also be laid on the buffer plate 34 to further absorb energy.

[0036] The working principle of this utility model is as follows: When polishing the outer ring of a tapered roller bearing, multiple sets of tapered roller bearings are placed in the V-shaped feeding groove of the feeding rack 1. The multi-stage cylinder 7 drives the support rod 8 to move. The support rod 8 and the inner wall support rod 14 are inserted into the interior of the outer ring of the tapered roller bearing. Then, the threaded sleeve 9 is rotated, and the expansion rod 13 is opened by the traction seat 10. The inner wall support rod 14 supports the inner wall of the bearing outer ring. The bearing is polished by the polishing wheel 22 and the edge grinding wheel 27. The polished bearing outer ring is transported to the top of the unloading rack 3. The electric telescopic shaft 31 drives the clamping plate 32 to clamp the bearing outer ring. Then, the threaded sleeve 9 and the traction seat 10 are reset, and the inner wall support rod 14 is released from supporting the inner wall of the bearing outer ring. The multi-stage cylinder 7 retracts the support rod 8. After the retraction is completed, the electric telescopic shaft 31 also drives the clamping plate 32 to retract, and the bearing outer ring falls into the V-shaped unloading groove.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
