Description

Technical Field

[0001] This utility model relates to the technical field of bearing ring production, specifically a feeding mechanism for bearing ring production. Background Technology

[0002] Bearing rings are key components of rolling bearings, and their production process directly affects the bearing's performance, precision, and lifespan. Bearing ring manufacturing is a highly technology-intensive industry, involving multiple fields such as materials science, heat treatment, precision machining, and automation control. A feeding mechanism is required to assist in the production of bearing rings.

[0003] A search revealed that prior art, under publication number CN220299629U, discloses a feeding mechanism for processing bearing rings, relating to the field of bearing ring processing technology. The mechanism includes a base plate and a storage assembly. The base plate has a fixed box on its upper side, and two corresponding supports are fixed to the rear end of the upper side of the base plate. A robotic arm moving assembly is mounted on the front side of the two supports, and a robotic arm adjusting assembly is connected to the lower side of the robotic arm moving assembly. A robotic arm is mounted on the side of the robotic arm adjusting assembly, and a robotic arm conveying assembly is mounted on the right side of the fixed box. The storage assembly includes a fixed plate, a storage frame, bearing rings, limiting posts, springs, and a limiting disc. The fixed plate is fixed inside the fixed box, and the storage frame is fixed to the upper side of the fixed plate. The storage frame contains evenly distributed bearing rings, enabling simultaneous conveying of multiple bearing rings while ensuring stability during conveying.

[0004] However, the following drawbacks still exist in this device and existing technology:

[0005] The existing feeding mechanism clamps the bearing rings by means of clamping. The clamping mechanism cannot be rotated or adjusted, and the angle of the bearing rings being fed cannot be changed. It requires manual adjustment, which increases labor waste, reduces the feeding effect of the bearing rings, and cannot meet the usage requirements. Utility Model Content

[0006] The purpose of this invention is to provide a feeding mechanism for the production of bearing rings.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A feeding mechanism for bearing ring production includes a base and a feeding beam. The feeding beam is positioned above the base, and a support frame is provided on the back of the feeding beam. Two support frames are provided, and their two ends are fixedly connected to the base and the feeding beam, respectively. A movable seat is provided on one side of the feeding beam, and a first connecting seat is provided below the movable seat. An electric actuator is provided above the first connecting seat and is fixedly connected to the movable seat. The telescopic end of the electric actuator is connected to the upper end of the first connecting seat. A first mounting groove is provided on the feeding beam, and a slider is provided inside the first mounting groove. The slider is slidably connected to the feeding beam. The slider is positioned on the movable seat. The back of the movable seat is fixedly connected to the slider and the movable seat. A second connecting seat is provided below the first connecting seat. A second motor is provided at the center of the first connecting seat and is connected to the first connecting seat by screws. The output end of the second motor is connected to the upper end of the second connecting seat. A second mounting groove is provided at the lower end of the second connecting seat. There are two second mounting grooves. A clamping plate is provided below the second connecting seat. There are two clamping plates. One end of the clamping plate extends into the interior of the second mounting groove and is slidably connected to the second connecting seat. Threaded holes are provided on the slider and the clamping plate. The cross-sections of the first mounting groove, the slider, the second mounting groove and the clamping plate are all trapezoidal.

[0009] By adopting the above technical solution, the bearing ring is placed below the second connecting seat, and the electric actuator is driven to lower the second connecting seat. Two clamping plates are placed on both sides of the end face of the bearing ring, and the clamping plates slide along the second mounting groove to clamp the bearing ring. Then, the electric actuator is driven to raise the second connecting seat, lifting the clamped bearing ring to a certain height. The slider slides along the first mounting groove, causing the clamped bearing ring to move laterally along the first mounting groove, thus feeding the bearing ring. The second motor is turned on to drive the second connecting seat to rotate. As the second connecting seat rotates, the clamped bearing ring rotates horizontally, changing the orientation of the clamped bearing ring.

[0010] Furthermore, a first motor is provided at one end of the feeding beam, and the first motor is connected to the feeding beam by screws. A one-way ball screw is provided inside the first mounting groove, and one end of the one-way ball screw is connected to the output end of the first motor. The one-way ball screw is threadedly connected to the slider.

[0011] By adopting the above technical solution, the first motor drives the one-way ball screw to rotate, and as the one-way ball screw rotates, it applies a pushing and pulling force to the slider, causing the slider to slide in the first mounting groove.

[0012] Furthermore, a third motor is provided at one end of the second connecting seat, and the third motor is connected to the second connecting seat by screws. A bidirectional ball screw is provided inside the second mounting groove, and one end of the bidirectional ball screw is connected to the output end of the third motor. The bidirectional ball screw is threadedly connected to the clamping plate, and the bidirectional ball screw is rotatably connected to the second connecting seat.

[0013] By adopting the above technical solution, the third motor drives the bidirectional ball screw to rotate. As the bidirectional ball screw rotates, it drives the two clamping plates to move synchronously in opposite directions along the second mounting groove, changing the distance between the two clamping plates. This allows for the clamping of bearing rings of different thicknesses, improving the feeding effect of the bearing rings and the rotational connection with the feeding beam.

[0014] Furthermore, the upper end of the second connecting seat is provided with a roller groove, and the roller groove is circular. The lower end of the first connecting seat is provided with six balls, and the six balls are arranged in a circular and equidistant manner at the lower end of the first connecting seat. One end of each ball extends into the interior of the roller groove, and the ball is in rolling connection with the first connecting seat and the second connecting seat.

[0015] By adopting the above technical solution, the ball rolls along the groove as the second connecting seat rotates, which can not only guide the rotating second connecting seat, but also reduce the rotational resistance of the second connecting seat and improve the rotational stability of the second connecting seat.

[0016] Furthermore, rubber pads are provided on the inner sides of both clamps, and the rubber pads are in close contact with the clamps.

[0017] By adopting the above technical solution, the rubber pad directly contacts the end face of the bearing race, thus protecting the clamped bearing race.

[0018] Furthermore, both clamping plates have protrusions on their inner sides, and the protrusions are fixedly connected to the clamping plates. The protrusions are cylindrical in shape.

[0019] By adopting the above technical solution, when clamping the bearing ring, the protrusion is inserted into the through hole of the bearing ring, which plays a limiting role in clamping the bearing ring and can prevent the bearing ring from shaking and slipping off during the feeding process.

[0020] Furthermore, a feeding rack is provided above the base and is fixedly connected to the base. A feeding trough is provided at the upper end of the feeding rack and is inclined. A baffle is provided above one end of the feeding rack and is connected to the feeding rack by screws.

[0021] By adopting the above technical solution, multiple bearing rings are placed in the feeding trough and arranged at an angle. When the bearing rings at the bottom of the feeding trough are clamped, the bearing rings in the feeding trough will automatically slide down, which can meet the needs of continuous feeding and eliminates the need for frequent manual feeding, thereby improving the feeding efficiency of bearing rings.

[0022] In summary, the beneficial technical effects of this utility model are as follows:

[0023] 1. The system employs a feeding beam, a first mounting slot, a first motor, a one-way ball screw, an electric actuator, a first connecting seat, a second connecting seat, a slider, a second mounting slot, clamping plates, a two-way ball screw, and a third motor. The third motor drives the two-way ball screw to rotate. As the two-way ball screw rotates, it causes the two clamping plates to move synchronously closer together along the second mounting slot. The two clamping plates clamp the bearing rings. The electric actuator drives the second connecting seat to rise and fall, changing the height of the clamped bearing rings. The first motor drives the one-way ball screw to rotate. As the one-way ball screw rotates, it applies a push-pull force to the slider, causing the slider to slide in the first mounting slot. This causes the clamped bearing rings to move laterally along the first mounting slot, thus achieving bearing ring feeding.

[0024] 2. A second motor is adopted, which drives the second connecting seat to rotate. As the second connecting seat rotates, it causes the clamped bearing ring to rotate horizontally, changing the orientation of the clamped bearing ring.

[0025] 3. The system employs a feeding rack, feeding trough, and baffle. Multiple bearing rings are placed in the feeding trough and arranged at an angle. The baffle limits the bearing rings at the bottom of the feeding trough. When the bearing rings at the bottom of the feeding trough are clamped, the bearing rings in the feeding trough will automatically slide down, which can meet the requirements of continuous feeding and eliminates the need for frequent manual feeding, thereby improving the feeding efficiency of bearing rings.

The upper end of the connecting seat 9 is connected to the feeding beam 2, which is provided with a first mounting groove 5. A slider 14 is installed inside the first mounting groove 5 and is slidably connected to the feeding beam 2. The slider 14 is located on the back of the movable seat 4 and is fixedly connected to the movable seat 4. A second connecting seat 10 is located below the first connecting seat 9. A second motor 15 is located at the center of the first connecting seat 9 and is connected to the first connecting seat 9 by screws. The output end of the second motor 15 is connected to the upper end of the second connecting seat 10, and the lower end of the second connecting seat 10 is provided with… The system has two second mounting slots 16. Two clamping plates 17 are located below the second connecting seat 10. One end of each clamping plate 17 extends into the interior of the second mounting slot 16 and is slidably connected to the second connecting seat 10. Both the slider 14 and the clamping plates 17 have threaded holes 23. The cross-sections of the first mounting slot 5, slider 14, second mounting slot 16, and clamping plates 17 are all trapezoidal. The bearing ring is placed below the second connecting seat 10, and the electric actuator 8 drives the second connecting seat 10 to descend, thus lowering the two clamping plates. Plate 17 is placed on both sides of the bearing race end face. Clamping plate 17 slides along the second mounting groove 16. The bearing race is clamped by the two clamping plates 17. Then, the electric push rod 8 drives the second connecting seat 10 to rise, lifting the clamped bearing race to a certain height. The slider 14 slides along the first mounting groove 5, driving the clamped bearing race to move laterally along the first mounting groove 5, realizing the feeding of the bearing race. The second motor 15 is turned on to drive the second connecting seat 10 to rotate. As the second connecting seat 10 rotates, the clamped bearing race rotates horizontally, changing the orientation of the clamped bearing race.

[0035] Please see Figure 1 and Figure 2A first motor 6 is installed at one end of the feeding beam 2, and the first motor 6 is connected to the feeding beam 2 by screws. A one-way ball screw 7 is installed inside the first mounting groove 5, and one end of the one-way ball screw 7 is connected to the output end of the first motor 6. The one-way ball screw 7 is threadedly connected to the slider 14, and the one-way ball screw 7 is rotatably connected to the feeding beam 2. A third motor 24 is installed at one end of the second connecting seat 10, and the third motor 24 is connected to the second connecting seat 10 by screws. A two-way ball screw 20 is installed inside the second mounting groove 16, and one end of the two-way ball screw 20 is connected to the third motor 6. The output end of 4 is connected to the bidirectional ball screw 20 and the clamping plate 17 through a threaded connection, and the bidirectional ball screw 20 is rotatably connected to the second connecting seat 10. The first motor 6 drives the unidirectional ball screw 7 to rotate. As the unidirectional ball screw 7 rotates, it applies a push-pull force to the slider 14, causing the slider 14 to slide in the first mounting groove 5. The third motor 24 drives the bidirectional ball screw 20 to rotate. As the bidirectional ball screw 20 rotates, it causes the two clamping plates 17 to move synchronously in opposite directions along the second mounting groove 16, changing the distance between the two clamping plates 17. This allows for the clamping of bearing rings of different thicknesses, improving the feeding effect of the bearing rings.

[0036] Please see Figure 2 and Figure 3 The upper end of the second connecting seat 10 is provided with a roller groove 22, which is circular. The lower end of the first connecting seat 9 is provided with six balls 21, which are equidistantly arranged in a circular pattern at the lower end of the first connecting seat 9.

This not only guides the rotating second connecting seat 10 but also reduces the rotational resistance of the second connecting seat 10 and improves the rotational stability of the second connecting seat 10. The rubber pad 19 directly contacts the end face of the bearing ring and protects the clamped bearing ring. When clamping the bearing ring, the protrusion 18 is inserted into the through hole of the bearing ring to limit the clamped bearing ring and prevent the bearing ring from shaking and slipping during the feeding process.

As the bidirectional ball screw 20 rotates, it causes the two clamping plates 17 to move synchronously along the second mounting groove 16, clamping the bearing race with the help of the two clamping plates 17. Then, the drive electric actuator 8 raises the second connecting seat 10, lifting the clamped bearing race to a certain height. The first motor 6 drives the unidirectional ball screw 7 to rotate. As the unidirectional ball screw 7 rotates, it applies a pushing and pulling force to the slider 14, causing... The slider 14 slides in the first mounting groove 5, causing the clamped bearing ring to move laterally along the first mounting groove 5, thus feeding the bearing ring; the second motor 15 is turned on to drive the second connecting seat 10 to rotate, and as the second connecting seat 10 rotates, the clamped bearing ring rotates horizontally, changing the orientation of the clamped bearing ring; multiple bearing rings are placed in the feeding groove 12 and arranged side by side at an angle. When the bearing ring at the bottom of the feeding groove 12 is clamped, the bearing ring in the feeding groove 12 will automatically slide down, which can meet the needs of continuous feeding, eliminating the need for frequent manual feeding and improving the feeding efficiency of the bearing ring.
