Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, and more specifically to tooling for processing large segmented thin bearings. Background Technology

[0002] Segmented bearings are a type of bearing used to support and rotate shafts. They consist of multiple segments, each capable of independently bearing the shaft's load and rotational force. This design provides higher load-carrying capacity and better rotational balance while simultaneously reducing friction and wear. Segmented bearings typically consist of two or more semi-annular segments that can be secured together by bolts or other connecting devices. The inner surface contacts the shaft, and the outer surface contacts the bearing housing. Segmented bearings are widely used in various mechanical equipment and devices, offering advantages in load-carrying capacity, rotational balance, and durability, making them suitable for a wide range of industrial and commercial applications.

[0003] In existing processing of large segmented thin bearings, workers typically use ropes to fix the two ends and the middle of the segmented bearing, then use a crane to move the segmented bearing to the processing table, and finally manually adjust the position of the segmented bearing to facilitate processing. Referring to Chinese utility model patent with authorization announcement number CN211439101U, a positioning and fixing mechanism for processing large bearings is disclosed, including a fixing table that is a rectangular plate structure with a V-shaped opening at the top. The wall surface of the lower part of the V-shaped opening of the fixing table is symmetrically provided with fixing grooves, and a first clamping screw and a second clamping screw are symmetrically provided on both sides of the fixing grooves. This patent has a simple structure and strong adaptability.

[0004] Regarding the aforementioned technologies, the inventors discovered that manually adjusting the position of segmented bearings increases the workload of workers and is detrimental to improving work efficiency. Furthermore, when moving the segmented bearings to the processing table, the surface of the segmented bearings may be damaged, thereby affecting the surface quality of the segmented bearings. Summary of the Invention

[0005] In view of this, the present invention provides a machining fixture for large segmented thin bearings, which can reduce the labor intensity of workers and improve the surface quality of segmented bearings.

[0006] To solve the above-mentioned technical problems, the present invention provides a large-scale segmented thin bearing processing fixture, comprising: a frame, erected on a horizontal plane; a first worktable, disposed on the frame, capable of supporting the middle part of the segmented bearing; an adjustment mechanism, disposed below the first worktable, capable of adjusting the position of the first worktable and restricting the movement of the segmented bearing; two second worktables, disposed on the frame, capable of supporting the two ends of the segmented bearing; a first moving mechanism, disposed below the two second worktables, capable of adjusting the position of the two ends of the segmented bearing; and a second moving mechanism, disposed on one side of the two second worktables, capable of readjusting the position of the segmented bearing again after the first moving mechanism has adjusted the position of the segmented bearing; wherein, the two second worktables are symmetrically arranged about the first worktable, and the adjustment mechanism restricts the movement of the segmented bearing after the first and second moving mechanisms have sequentially adjusted the position of the segmented bearing.

[0007] By adopting the above technical solution, when it is necessary to position the segmented bearing, firstly, the segmented bearing is moved above the device using a crane. Then, the first worktable is raised using an adjustment mechanism to support the middle of the segmented bearing, and the crane's restriction on the middle of the segmented bearing is released. Next, according to the size of the segmented bearing, the position of the first worktable is adjusted using the adjustment mechanism so that both ends of the segmented bearing can fall onto the second worktable. Then, the first and second worktables are aligned on the same horizontal plane using the adjustment mechanism, and the segmented bearing is placed on the device. Then, the crane's restriction on both ends of the segmented bearing is released. Next, the position of both ends of the segmented bearing is adjusted using the first moving mechanism to facilitate the processing of the segmented bearing. After the first moving mechanism is adjusted, if one end of the segmented bearing protrudes too far from the two second worktables, the position of the segmented bearing is adjusted using the second moving mechanism. After adjustment, the segmented bearing is fixed using the adjustment mechanism. Using this device to adjust and fix the position of the segmented bearing reduces the labor intensity of workers and improves work efficiency.

[0008] The adjustment mechanism can adjust the position of the first worktable in the horizontal or vertical direction to guide the segmented bearing onto the device, thereby reducing the probability of the segmented bearing being damaged when it falls onto the device. The first and second moving mechanisms adjust the position of the segmented bearing in sequence, thereby improving the accuracy of the segmented bearing processing position and thus improving work efficiency.

[0009] Optionally, the adjustment mechanism includes: a first rotation source, fixedly mounted on the first worktable, the output shaft of the first rotation source being fixedly connected to a first lead screw, and a pressing block being slidably connected to the first lead screw; a movable housing, slidably connected to the frame and disposed below the first worktable; a first linear actuator, fixedly mounted inside the movable housing, the output shaft of the first linear actuator being fixedly connected to the lower surface of the first worktable; and a second rotation source, fixedly mounted on the frame, the output shaft of the second rotation source being fixedly connected to a second lead screw, a first slider being slidably connected to the second lead screw, and the first slider being fixedly connected to the movable housing.

[0010] By adopting the above technical solution, when the position of the segmented bearing needs to be guided, the first linear actuator is first activated to drive the first worktable to rise and support the middle part of the segmented bearing. Then, according to the size of the segmented bearing, the second rotation source is activated. The output shaft of the second rotation source drives the second lead screw to rotate. The rotation of the second lead screw drives the first slider to move. The first slider drives the moving housing to move. The moving housing drives the first worktable to move, so that when the segmented bearing continues to descend, both ends of the segmented bearing can fall onto the second worktable. Then, the first linear actuator is activated to drive the first worktable to descend so that the first worktable and the second worktable are on the same horizontal plane. When the processing position of the segmented bearing is determined, the first rotation source is activated, and then the first lead screw starts to rotate and drives the extrusion block to move and clamp the segmented bearing, so as to facilitate the processing of the segmented bearing.

[0011] The adjustment device guides the segmented bearing when it is moved to the device. The adjustment device controls the first worktable to rise so that the first worktable supports the segmented bearing first, thereby reducing the probability of damaging the surface quality of the segmented bearing by placing it directly on the segmented bearing. Moreover, the arrangement of the second rotation source, the second lead screw, the second slider and the moving housing allows the first worktable to move horizontally, allowing the segmented bearing to fall onto the device for processing. This not only reduces the labor intensity of the workers, but also improves work efficiency.

[0012] Optionally, the first moving mechanism includes a second rotating source fixedly mounted on the frame. The output shaft of the second rotating source is fixedly connected to a first bevel gear. The first bevel gear meshes with two second bevel gears. A third lead screw is fixedly connected to the end of each of the two second bevel gears away from the first bevel gear. A second slider is slidably connected to each of the two third lead screws. A roller is fixedly connected to the upper surface of each of the two second sliders.

[0013] By adopting the above technical solution, when it is necessary to adjust the position of the two ends of the bearing on the second worktable, the second rotation source is first started. The second rotation source drives the first bevel gear to rotate, and then the first bevel gear drives the two second bevel gears to rotate. The two second bevel gears drive the two third lead screws to start rotating. Then the two second sliders start to move on the third lead screws. Then the two second sliders drive the two rollers to start moving. Then the two rollers abut against the two ends of the segmented bearing and push the two ends of the segmented bearing to move, thereby adjusting the position of the segmented bearing. On the one hand, it can reduce the labor intensity of workers, and on the other hand, it is conducive to improving work efficiency.

[0014] Optionally, the second moving mechanism includes: a second linear driver, fixedly mounted on the frame and located between the first worktable and the second worktable; a moving frame, fixedly connected to the output shaft of the second linear driver; a fourth rotation source, fixedly mounted on the moving frame; a rotating roller, rotatably connected to the moving frame and capable of driving the rotating roller to rotate; and a support roller, rotatably connected to the moving frame and located on the same horizontal plane as the rotating roller.

[0015] By adopting the above technical solution, when adjusting the position of both ends of the segmented bearing, the second linear drive is first started to drive the moving frame to rise. As the moving frame rises, the rotating roller and the support roller jointly support the segmented bearing, thereby driving the segmented bearing to rise. Then, the fourth rotation source is started, and the fourth rotation source drives the rotating roller to rotate. According to the position of the segmented bearing on the second worktable, the fourth rotation source drives the rotating roller to rotate, so that the positions of both ends of the segmented bearing are symmetrical about the first worktable, which facilitates the processing of the segmented bearing, thereby reducing the labor intensity of workers and improving work efficiency.

[0016] The second moving mechanism allows for the adjustment of the position of the segmented bearing after the first moving mechanism has adjusted it. This improves the accuracy of the segmented bearing's position, which is beneficial for processing the segmented bearing. It also reduces the workload of workers and increases work efficiency. Furthermore, after the second moving mechanism adjusts the position of the segmented bearing, the first moving mechanism clamps the segmented bearing to facilitate its processing.

[0017] Optionally, there are two second moving mechanisms, and the two second moving mechanisms are symmetrically arranged about the first worktable.

[0018] By adopting the above technical solution, the second moving mechanism is configured to simultaneously adjust the position of the segmented bearing, thereby accelerating the adjustment speed of the segmented bearing position and thus improving work efficiency; moreover, the two second moving mechanisms are symmetrically arranged about the first worktable, which not only improves the aesthetics of the device, but also increases the speed of adjusting the position of the segmented bearing, thereby improving work efficiency.

[0019] Optionally, the extrusion block is configured as an extrusion block with one side being an arc surface.

[0020] By adopting the above technical solution, the section of the extrusion block near the segmented bearing is set as an arc shape, so that it can better fit the segmented bearing during the clamping process. This protects the surface of the segmented bearing while clamping it, which is conducive to improving the surface quality of the segmented bearing.

[0021] Optionally, the bottom of the frame is provided with multiple support bases.

[0022] By adopting the above technical solution, multiple support seats are set at the bottom of the frame, making the device more stable when positioning and processing segmented bearings, thus facilitating the processing of segmented bearings and improving the stability of the device.

[0023] Optionally, the first worktable, the second worktable, the extrusion block, and the roller may be made of rubber or polymer materials.

[0024] By adopting the above technical solution, the first worktable, the second worktable, the extrusion block, and the roller are made of rubber or polymer material, so that when the segmented bearing comes into contact with the above structure, the surface of the segmented bearing can be protected, thereby improving the surface quality of the segmented bearing.

[0025] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0026] 1. The adjustment mechanism can adjust the position of the first worktable in the horizontal or vertical direction to guide the segmented bearing onto the device, thereby reducing the probability of the segmented bearing being damaged when it falls onto the device; the first moving mechanism and the second moving mechanism adjust the position of the segmented bearing in sequence, thereby improving the accuracy of the segmented bearing processing position and thus improving work efficiency.

[0027] 2. After the adjustment mechanism, the first moving mechanism and the second moving mechanism adjust the position of the segmented bearing in sequence, the position of the segmented bearing can be restricted by the adjustment mechanism to facilitate the processing of the segmented bearing. The adjustment mechanism can not only adjust the position of the segmented bearing, but also restrict the position of the segmented bearing. Moreover, the adjustment mechanism has a simple structure and strong adaptability.

[0028] 3. By setting the contact point with the segmented bearing to a flexible material, the probability of damage to the surface of the segmented bearing is reduced when it comes into contact with this device, thereby improving the surface quality of the segmented bearing.

[0029] 4. By setting two second moving mechanisms and symmetrically arranging them about the first worktable, not only is the aesthetics of the device improved, but the speed of adjusting the position of the segmented bearings can also be accelerated, thereby improving work efficiency.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of the present invention. Figure 1-4The technical solutions of the embodiments of the present invention will be clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0036] Reference Figure 1 A large segmented thin bearing processing fixture includes a frame 1 erected on a horizontal plane. The frame 1 is equipped with a first worktable 2 that supports the middle part of the segmented bearing and two second worktables 4 that support the two ends of the segmented bearing. The frame 1 is also equipped with an adjustment mechanism 3 that can adjust the position of the segmented bearing in the horizontal or vertical direction and restrict the movement of the segmented bearing, a first moving mechanism 5 that can adjust the position of the two ends of the segmented bearing, and a second moving mechanism 6 that can further adjust the position of the two ends of the segmented bearing. The two second worktables 4 are symmetrically arranged about the first worktable 2. The adjustment mechanism 3 restricts the movement of the segmented bearing after the first moving mechanism 5 and the second moving mechanism 6 adjust the position of the two ends of the segmented bearing in sequence.

[0037] When positioning a segmented bearing, the first step is to move the bearing above the device using a crane. Then, the first worktable 2 is raised using the adjusting mechanism 3 to support the middle of the bearing, and the crane's restriction on the middle of the bearing is released. Next, the position of the first worktable 2 is adjusted using the adjusting mechanism 3 according to the size of the bearing so that both ends of the bearing can rest on the second worktable 4. Then, the first worktable 2 and the second worktable 4 are aligned on the same horizontal plane using the adjusting mechanism 3, and the bearing is placed on the device. The crane's restriction on both ends of the bearing is then released. Next, the position of both ends of the bearing is adjusted using the first moving mechanism 5 to facilitate processing. After the first moving mechanism 5 is adjusted, if one end of the bearing extends too far from the two second worktables 4, the position of the bearing is adjusted using the second moving mechanism 6. After adjustment, the bearing is fixed using the adjusting mechanism 3. Using this device to adjust and fix the position of the bearing reduces the worker's workload while improving work efficiency.

[0038] Reference Figure 2The adjustment mechanism 3 includes a first rotation source 31 fixedly installed on the first worktable 2. The output shaft of the first rotation source 31 is fixedly connected to a horizontally arranged first lead screw 32. A pressing block 33 is slidably connected to the first lead screw 32, and the side wall of the pressing block 33 near the segmented bearing is set as an arc-shaped side wall. A movable housing 34 slidably connected to the frame 1 is provided below the first worktable 2. A first linear driver 35 is fixedly installed on the bottom wall inside the movable housing 34. The output shaft of the first linear driver 35 is vertically arranged and fixedly connected to the lower surface of the first worktable 2. A second rotation source 36 is also fixedly installed on the frame 1. The output shaft of the second rotation source 36 is fixedly connected to a horizontally arranged second lead screw 37. A first slider 38 is slidably connected to the second lead screw 37 and fixedly connected to the side wall of the movable housing 34 near the first slider 38. The first rotation source 31 and the second rotation source 36 can be devices such as motors or rotary cylinders whose output shafts can rotate. The first linear driver 35 can be devices such as cylinders or hydraulic cylinders whose output shafts can move linearly.

[0039] When the segmented bearing needs to be guided to its position, the first linear actuator 35 is activated to raise the first worktable 2 to support the middle of the segmented bearing. Then, according to the size of the segmented bearing, the second rotation source 36 is activated. The output shaft of the second rotation source 36 drives the second lead screw 37 to rotate. The rotation of the second lead screw 37 drives the first slider 38 to move. The first slider 38 drives the moving housing 34 to move. The moving housing 34 drives the first worktable 2 to move so that when the segmented bearing continues to descend, both ends of the segmented bearing can fall onto the second worktable 4. Then, the first linear actuator 35 is activated to lower the first worktable 2 so that the first worktable 2 and the second worktable 4 are on the same horizontal plane. After the processing position of the segmented bearing is determined, the first rotation source 31 is activated. Then, the first lead screw starts to rotate and drives the pressing block 33 to move and clamp the segmented bearing to facilitate the processing of the segmented bearing.

[0040] Reference Figure 3 The first moving mechanism 5 includes a third rotation source 51 fixedly mounted on the frame 1. The output shaft of the third rotation source 51 is fixedly connected to a first bevel gear 52. The first bevel gear 52 meshes with two second bevel gears 53. A third lead screw 54 is fixedly connected to the end of each of the two second bevel gears 53 away from the first bevel gear 52. A second slider 55 is slidably connected to each of the two third lead screws 54. A roller shaft 56 that is slidably connected to the upper surface of each of the two second sliders 55 is fixedly connected to the upper surface of the roller shaft 56, which is slidably connected to the second worktable 4. The third rotation source 51 can be a device such as a motor or a rotary cylinder whose output shaft can rotate.

[0041] When it is necessary to adjust the position of the two ends of the bearing on the second worktable 4, the second rotation source 36 is first started. The second rotation source 36 drives the first bevel gear 52 to rotate. Then the first bevel gear 52 drives the two second bevel gears 53 to rotate. The two second bevel gears 53 drive the two third lead screws 54 to start rotating. Then the two second sliders 55 start to move on the third lead screws 54. Then the two second sliders 55 drive the two rollers 56 to start moving. Then the two rollers 56 abut against the two ends of the segmented bearing and push the two ends of the segmented bearing to move, thereby adjusting the position of the segmented bearing. On the one hand, it can reduce the labor intensity of the workers, and on the other hand, it is conducive to improving work efficiency.

[0042] Reference Figure 4 The second moving mechanism 6 includes a second linear drive 61 fixedly mounted on the frame 1, located between the first worktable 2 and the second worktable 4. The output shaft of the second linear drive 61 is vertically arranged and fixedly connected to a moving frame 62. A fourth rotation source 63 is fixedly mounted on the moving frame 62. A first gear is fixedly connected to the output shaft of the fourth rotation source 63. The first gear is connected to a second gear via chain drive. A rotating roller 64 is fixedly connected to one end of the second gear near the fourth rotation source 63. A support roller 65, located on the same horizontal plane as the rotating roller 64, is rotatably connected to the moving frame 62. The second linear drive 61 can be a cylinder or hydraulic cylinder, or other device whose output shaft can achieve linear movement.

[0043] When the positions of both ends of the segmented bearing need to be adjusted again, the second linear drive 61 is first activated to raise the moving frame 62. As the moving frame 62 rises, the rotating roller 64 and the support roller 65 jointly support the segmented bearing, thereby raising the segmented bearing. Then, the fourth rotation source 63 is activated, which drives the rotating roller 64 to rotate. The rotation direction of the rotating roller 64 is controlled according to the position of the segmented bearing on the second worktable 4, so that the positions of both ends of the segmented bearing are symmetrical about the first worktable 2, which facilitates the processing of the segmented bearing, thereby reducing the labor intensity of the workers and improving work efficiency.

[0044] The implementation principle of the large segmented thin bearing processing fixture in this application embodiment is as follows: First, the middle and both ends of the segmented bearing are tied with ropes. Then, the segmented bearing is lifted and moved above the device using a crane or other equipment. Next, the first linear actuator 35 is activated, which drives the first worktable 2 to rise until it contacts the segmented bearing. The segmented bearing is then slowly lowered by the first linear actuator 35 and the crane. When the first worktable 2 and the second worktable 4 are on the same horizontal plane, the first linear actuator 35 is turned off. Then, according to the size of the segmented bearing, the second rotation source 36 is activated. The second rotation source 36 drives the second lead screw to rotate, thereby moving the first slider 38, the movable housing 34, and the first worktable 2 in the horizontal direction. When both ends of the segmented bearing can fall onto the second worktable 4, the second rotation source 36 is turned off, and the ropes on the segmented bearing are removed. Then, the third rotation source 51 is activated. The power source 51 drives the first bevel gear 52 to rotate, the first bevel gear 52 drives the two second bevel gears 53 to rotate, the second bevel gears 53 drive the two third lead screws 54 to rotate, and the third lead screws 54 drive the second slider 55 and the roller shaft 56 to move. According to the processing position of the segmented bearing, the roller shaft 56 abuts against the segmented bearing and moves it to the processing position. When the segmented bearing is longer at one end and shorter at the other end on the two second worktables 4, the second linear drive 61 is started. The second linear drive 61 drives the moving frame 62 to rise. The rise of the moving frame 62 causes the support roller 65 and the rotating roller 64 to rise and drive the segmented bearing to rise. Then, the fourth rotation source 63 is started to drive the rotating roller 64 to rotate, thereby adjusting the position of the two ends of the segmented bearing. After the position of the segmented bearing is adjusted, the first rotation source 31 is started to drive the first lead screw 32 to rotate. The rotation of the first lead screw drives the extrusion block 33 to move to abut against the segmented bearing, so as to facilitate the processing of the segmented bearing.
