Description

Technical Field

[0001] This invention relates to the field of bearing ring processing technology, specifically to an integrated machining equipment for turning and polishing TSP bearing rings. Background Technology

[0002] Bearing rings are the core components of bearings. They are ring-shaped and consist of an inner ring and an outer ring. They are the key components for bearing rotation and load bearing, and are also the objects processed by this equipment. The inner ring usually mates with the shaft and rotates synchronously with it. Its inner surface has raceways to accommodate the rolling of steel balls and rollers. The outer ring mates with the bearing housing and is fixed in place. Its outer surface can be designed as cylindrical or other shapes according to installation requirements. Its inner surface also has corresponding raceways. Bearing rings need to undergo precision machining such as turning and polishing to ensure the dimensional accuracy, surface finish, and coaxiality of the inner hole, outer circle, end face, and raceways. This ensures smooth bearing rotation, wear resistance, and long service life. They are widely used in various rotating equipment such as machinery, automobiles, and home appliances.

[0003] In existing technologies, traditional bearing ring processing often adopts a separate processing mode, requiring manual transfer of the workpiece to polishing equipment for subsequent polishing. The process is scattered and cumbersome. The workpiece is prone to positioning deviation during clamping, resulting in decreased processing accuracy and affecting the finished product qualification rate. The clamping mechanism of traditional processing equipment is mostly a single clamping method, which makes it difficult to ensure the coaxiality of the inner and outer rings of the bearing and is prone to processing eccentricity, making it difficult to meet the high efficiency and high precision requirements of modern bearing processing.

[0019] like Figure 2 and Figure 3 As shown, the feeding assembly 4 includes a slide 41, which is fixedly installed on the top of the support frame 1. The other end of the slide 41 is located on the top of the base 2 and a support plate 31 is fixedly installed at the bottom. The support block 43 is fixedly installed on the top wall of the base 2. The top of the slide 41 is inclined and an inclined sliding groove 13 is provided on the top of the slide 41. A stop block 42 is fixedly installed at one end of the slide 41 on the base 2. Multiple workpieces 11 are placed in the sliding groove 13. A collection box 10 is placed in front of the support block 43.

[0020] The slide 41 is fixed to the top of the support frame 1. Its top end is an inclined surface with an inclined sliding groove 13 inside. The bottom end extends to the top of the base 2. The stop block 42 is installed at the end of the slide 41 near the base 2 to position and limit the workpiece 11 to be processed. The support block 43 is fixed to the top wall of the base 2. A collection box 10 is placed on the front side to collect the finished products. Multiple workpieces 11 are stacked in the sliding groove 13 and automatically slide down the inclined groove to the stop block 42 by gravity. After processing, the workpiece 11 falls into the collection box 10, completing the automatic unloading and collection.

[0021] like Figure 3 and Figure 4 As shown, the drive mechanism 3 includes a support plate 31, which is fixedly installed on the rear side wall of the base 2. A square groove 12 is provided on the surface of the support plate 31. A connecting block 32 is provided inside the square groove 12. A moving block 36 is fixedly installed on the rear side wall of the connecting block 32. A working box 39 is fixedly installed on the front side wall of the connecting block 32. The rear end of the third cylinder 98 passes through the front side wall of the working box 39 and is fixedly installed on the inner rear side wall. The working box 39 has round holes 17 on both sides of the third cylinder 98. Through holes 16 are provided on both sides of the round holes 17.

[0022] The surface of the movable block 36 is threaded with a first lead screw 34. The two ends of the first lead screw 34 are respectively provided with fixed plates 33. A guide rod 35 is fixedly installed between the two fixed plates 33. The guide rod 35 passes through the movable block 36 and is slidably connected to it. The two fixed plates 33 are respectively fixedly installed on the upper and lower ends of the rear side wall of the support plate 31. The bottom of the bottom fixed plate 33 is fixedly installed with a first motor 38. The output end of the first motor 38 passes through the fixed plate 33 and is fixedly connected to one end of the first lead screw 34. The support plate 31 has sliding grooves 18 on both sides of the square groove 12. The two sides of the movable block 36 are fixedly connected with sliders 37, which are slidably installed in the sliding grooves 18.

[0023] The support plate 31 is fixed to the rear side wall of the base 2, and a square groove 12 is opened on the surface. The moving block 36 is connected to the work box 39 through the connecting block 32. The sliders 37 on both sides of the moving block 36 are embedded in the sliding grooves 18 of the support plate 31 to realize the vertical movement guidance. The first motor 38 drives the first lead screw 34 to rotate. The moving block 36 is threadedly connected to the first lead screw 34 and slides on the guide rod 35 at the same time to ensure that the work box 39 moves in the vertical direction and avoids shaking. The third cylinder 98 and the outer ring fixing mechanism 8 are installed inside the work box 39. The output end of the third cylinder 98 is connected to the round shaft 91 of the inner ring fixing mechanism 9 to realize the forward and backward feed of the inner ring fixing mechanism 9. This drives the inner ring fixing mechanism 9 and the outer ring fixing mechanism 8 to complete the vertical position switching and horizontal feed, which is suitable for different processing stages such as turning and polishing.

[0024] The operator places multiple bearing ring blanks 11 into the sliding groove 13 of the slide rail 41. The blanks 11 slide down the inclined sliding groove 13 by gravity to the stop block 42, completing the loading and positioning. The first motor 38 of the drive mechanism 3 starts, driving the first lead screw 34 to rotate, which drives the moving block 36, the work box 39, the inner ring fixing mechanism 9, and the outer ring fixing mechanism 8 to move upward to the loading station, so that the round shaft 91 is aligned with the inner hole of the blank 11.

[0025] like Figure 3 As shown, the transposition assembly 7 includes a second motor 71 and a fixing block 72. The fixing block 72 is fixedly installed on one side wall of the front end of the base 2, and the second motor 71 is fixedly installed on one side wall of the fixing block 72. The output end of the second motor 71 passes through the fixing block 72 and is fixedly installed with a second lead screw 73. The other end of the second lead screw 73 is rotatably connected to one side wall of the support frame 1. The bottom ends of the turning mechanism 5 and the polishing mechanism 6 are both provided with threaded grooves, and the second lead screw 73 is threadedly connected to its threaded grooves. T-blocks are fixedly installed on the bottom walls of the turning mechanism 5 and the polishing mechanism 6. A T-slot is provided at the corresponding position on the top of the base 2, and the T-block is slidably installed in the T-slot. The second lead screw 73 is driven by the second motor 71, and its two ends are rotatably connected to the fixed block 72 and the support frame 1 respectively. The bottom ends of the turning mechanism 5 and the polishing mechanism 6 are connected to the second lead screw 73 through threaded grooves. The bottom of the turning mechanism 5 and the polishing mechanism 6 are fixed with T-shaped blocks, which are embedded in the T-shaped grooves on the top of the base 2 to slide, ensuring stability during movement. This enables automatic switching of the horizontal work positions of the turning mechanism 5 and the polishing mechanism 6, completing the turning and polishing processes on the same machine tool without the need to transfer the workpiece 11, thus avoiding repeated clamping errors.

[0026] like Figure 5 As shown, the inner ring fixing mechanism 9 includes a round shaft 91, a double-acting lead screw 93, a moving ring 94, and an arc-shaped support plate 96. The round shaft 91 is located on the front side of the drive mechanism 3. An installation groove 15 is provided inside the round shaft 91. The double-acting lead screw 93 is installed in the installation groove 15. The moving ring 94 is symmetrically installed at both ends of the double-acting lead screw 93. A support rod 95 is rotatably connected to the surface of the moving ring 94. The other end of the support rod 95 is rotatably connected to the bottom end of the arc-shaped support plate 96.

[0027] One end of the bidirectional lead screw 93 is rotatably mounted on one end of the mounting groove 15, and the other end of the bidirectional lead screw 93 is equipped with a fourth motor 92. The rear end of the fourth motor 92 is fixedly mounted on the other end of the mounting groove 15. The output end of the fourth motor 92 is fixedly connected to one end of the bidirectional lead screw 93. The moving ring 94 is threadedly connected to the bidirectional lead screw 93. The surface of the moving ring 94 is provided with a sliding hole, and a round rod 97 is slidably connected in the sliding hole. The two ends of the round rod 97 are fixedly mounted on both ends of the mounting groove 15.

[0028] Four sets of rotating blocks are fixedly installed at equal intervals on the surfaces of the two moving rings 94. The bottom end of the support rod 95 is rotatably mounted on the rotating blocks. Rotating plates are fixedly installed at both ends of the bottom of the four arc-shaped support plates 96. The other end of the support rod 95 is rotatably mounted on the rotating plate. A third cylinder 98 is fixedly installed at the rear end of the round shaft 91. Four arc-shaped grooves 14 are equally spaced on the surface of the round shaft 91. The arc-shaped grooves 14 are adapted to the arc-shaped support plates 96. The arc-shaped support plates 96 can extend to the outside through the arc-shaped grooves 14. The cylindrical shaft 91 has four equally spaced arc-shaped grooves 14 on its surface and an internal mounting groove 15 to accommodate the bidirectional lead screw 93, moving rings 94, etc. The fourth motor 92 drives the bidirectional lead screw 93, with opposite threads at both ends. Two moving rings 94 are symmetrically installed on the shaft 97. The moving rings 94 slide on the cylindrical shaft 97 to prevent rotation with the lead screw and ensure linear movement. The surface of the moving rings 94 is hinged to the support rod 95 through a rotating block. The other end of the support rod 95 is hinged to the rotating plate at the bottom of the arc-shaped support plate 96. When the bidirectional lead screw 93 rotates, the two moving rings 94 move towards each other, pushing the arc-shaped support plate 96 out of the arc-shaped groove 14 through the support rod 95, thus achieving internal support-type tension clamping of the bearing inner ring. When reversing, the arc-shaped support plate 96 retracts, releasing the inner ring and fixing the bearing inner ring through internal support, ensuring that the inner ring is coaxial with the cylindrical shaft 91, avoiding eccentricity during processing, and ensuring uniform tension to prevent deformation of the workpiece 11.

[0029] The third cylinder 98 starts, pushing the round shaft 91 forward and inserting it into the inner hole of the bearing inner ring. The fourth motor 92 starts, driving the bidirectional lead screw 93 to rotate. The two moving rings 94 at both ends move towards each other along the round rod 97. The moving rings 94 push the arc-shaped support plate 96 outward from the arc-shaped groove 14 through the support rod 95, tightening the inner wall of the bearing inner ring and realizing the coaxial clamping of the inner ring.

[0030] The first motor 38 starts, driving the first lead screw 34 to rotate, which in turn moves the work box 39 and the clamped workpiece 11 upward. Then, the third cylinder 98 starts, pushing the round shaft 91 forward. The second motor 71 of the shifting component 7 starts, driving the second lead screw 73 to rotate, moving the turning mechanism 5 horizontally to the machining position, so that the cutting tool is aligned with the surface of the collar to be machined. The third cylinder 98 finely adjusts the feed, pushing the workpiece 11 to move in the direction of the cutting tool. During the turning process, the cutting fluid spray sprays cutting fluid into the machining area to achieve cooling, lubrication and chip removal, ensuring machining accuracy and surface quality.

[0031] After the turning is completed, the second motor 71 drives the second lead screw 73 to move the turning mechanism 5 to one side and the polishing mechanism 6 to move horizontally to the machining position. The polishing wheel of the polishing mechanism 6 is aligned with the working surface of the ring that has been turned. The third cylinder 98 finely adjusts the feed so that the polishing wheel contacts the surface of the ring, removes the turning texture, reduces the surface roughness, and improves the smoothness and precision. During the polishing process, the polishing liquid is continuously sprayed to cool the polishing wheel and wash away the polishing debris, so as to avoid scratching the surface of the workpiece 11.

[0032] like Figure 6 As shown, the outer ring fixing mechanism 8 is arranged on both sides of the inner ring fixing mechanism 9. The outer ring fixing mechanism 8 includes symmetrically arranged first cylinders 81. The first cylinders 81 are fixedly installed on the rear side wall inside the working box 39. The output end of the first cylinder 81 extends to the outside through the circular hole 17. A connecting rod 82 is provided on one side of the first cylinder 81. The connecting rod 82 is slidably installed in the through hole 16. L-shaped plates 83 are fixedly installed on the output ends of both first cylinders 81. A fixing sleeve 86 is fixedly installed on the front side wall of the L-shaped plate 83. A third motor 84 is fixedly installed on one side wall of the L-shaped plate 83. The output end of the third motor 84 passes through one end of the L-shaped plate 83 and is fixedly installed with a second cylinder 85. The second cylinder 85 passes through the fixing sleeve 86. A bearing 88 is provided at the connection between the second cylinder 85 and the fixing sleeve 86. An arc plate 87 is fixedly installed on the output end of the second cylinder 85. One end of the connecting rod 82 passes through the through hole 16 and is fixedly connected to the rear side wall of the L-shaped plate 83.

[0033] The first cylinder 81 is symmetrically installed on the rear side wall inside the work box 39. Its output end is connected to the L-shaped plate 83. The connecting rod 82 passes through the through hole 16 and is fixed to the rear side wall of the L-shaped plate 83 to ensure that the L-shaped plate 83 moves smoothly back and forth. The third motor 84 is fixed to the side wall of the L-shaped plate 83. Its output end is connected to the second cylinder 85. The second cylinder 85 passes through the fixing sleeve 86. A bearing 88 is set at the connection to reduce rotational friction. The output end of the second cylinder 85 is fixed to the arc plate 87. The two symmetrical arc plates 87 can clamp the outer ring of the bearing from the outside. The third motor 84 drives the outer ring to rotate. With the help of turning and polishing, the outer ring of the bearing can be adjusted for clamping and rotation.

[0034] The third motor 84 drives the workpiece 11 to rotate. The cutting mechanism 5 turns the rear end face to ensure the flatness and perpendicularity of the end face. The polishing mechanism 6 polishes the rear end face to improve the surface finish. During the processing, cutting fluid is sprayed to cool the tool and workpiece 11 and flush away iron filings and debris to avoid scratching the surface of workpiece 11. After the inner ring surface and the rear end face are processed, the second cylinder 85 retracts, which drives the arc plate 87 to loosen the outer ring. The workpiece 11 falls into the collection box 10 below by gravity, completing one processing cycle. The drive mechanism 3 resets, realizing continuous automated production.
