Description

Technical Field

[0001] This application relates to the field of fixture technology, for example to a fixture for polishing castings. Background Technology

[0002] A polishing machine for polishing castings is disclosed in related technology (Announcement No.: CN221774229U), including a U-shaped frame. A third housing is disposed inside the U-shaped frame. The lower end face of the third housing and the lower end of the interior of the U-shaped frame are rotatably connected to a rotating shaft via bearings. Clamping plates are fixedly connected to opposite sides of the two rotating shafts. A third cylinder is fixedly connected to the upper end face of the U-shaped frame, and the output end of the third cylinder passes through the upper end face of the U-shaped frame and is fixedly connected to the third housing. A second motor is installed inside the third housing, and the output end of the second motor passes through the lower end face of the interior of the third housing and is fixedly connected to the upper end of the upper rotating shaft.

[0003] In implementing the above embodiments, at least the following problems were found in the related technology:

[0004] This polishing machine for castings uses a third cylinder to adjust the height of the third housing, thereby changing the distance between the two clamping plates and clamping the casting in place. Then, controlling the second motor drives a connected shaft to rotate. Supported by another shaft, the two clamping plates rotate the casting, allowing for polishing of different surfaces. However, to significantly adjust the distance between the clamping plates and clamp castings with varying heights, the moving end of the third cylinder needs sufficient length. This results in a relatively large cylinder body. Furthermore, since the overall height of the device is approximately twice the length of the third cylinder, it occupies a large amount of vertical space, making it unsuitable for use in factories with low ceilings.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0016] Optionally, it further includes: reinforcing plates, which are respectively installed at the bends of the first support plate and the second support plate.

[0017] The fixture for sectioning castings provided in this disclosure can achieve the following technical effects:

[0018] This disclosure provides a fixture for profiled castings, comprising a first support plate, a first rotating shaft, a first linear slide, a second support plate, a second rotating shaft, clamping plates, a motor, a driving belt gear, a driven belt gear, and a synchronous toothed belt. The first rotating shaft is rotatably mounted on the first support plate and can rotate relative to it. The first linear slide is mounted on the first support plate, and its moving end moves along the axial direction of the first rotating shaft to provide drive and achieve linear movement. The second support plate is mounted on the moving end of the first linear slide and moves linearly under its drive. The second rotating shaft is rotatably mounted on the second support plate and coaxial with the first rotating shaft, and can rotate relative to it. Clamping plates are respectively mounted on opposite ends of the first and second rotating shafts to clamp the castings.

Through the synchronous toothed belt, the first rotating shaft rotates. Supported by the second rotating shaft, the two clamping plates rotate the casting, facilitating grinding of different surfaces.

However, the moving distance of the moving end of the first linear slide is close to the length of the first linear slide itself. Therefore, compared to a design using a cylinder as the drive component, the height of the device is reduced by about half, minimizing the vertical space occupied.

[0037] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides a fixture for profiled castings, including a first support plate 1, a first rotating shaft 2, a first linear slide 3, a second support plate 4, a second rotating shaft 5, a clamping plate 6, a motor 7, a driving belt gear, a driven belt gear, and a synchronous toothed belt 8. The first rotating shaft 2 is rotatably mounted on the first support plate 1 and can rotate relative to the first support plate 1. The first linear slide 3 is mounted on the first support plate 1, and its moving end moves along the axial direction of the first rotating shaft 2 to provide drive and achieve linear movement. The second support plate 4 is mounted on the moving end of the first linear slide 3 and moves linearly under the drive of the first linear slide 3. The second rotating shaft 5 is rotatably mounted on the second support plate 4 and is coaxially distributed with the first rotating shaft 2; the second rotating shaft 5 can rotate relative to the second support plate 4. The clamping plates 6 are respectively mounted on opposite ends of the first rotating shaft 2 and the second rotating shaft 5 for clamping the castings. Motor 7 is mounted on the first support plate 1. The axis of the rotating end of motor 7 is parallel to the axis of the first rotating shaft 2, providing driving force to achieve rotational motion. A driving belt gear is mounted on the rotating end of motor 7 and rotates under the drive of motor 7. A driven belt gear is mounted on the first rotating shaft 2 to drive the first rotating shaft 2 to rotate. A synchronous toothed belt 8 is fitted onto the driving pulley and the driven belt gear to transmit driving force.

[0038] This embodiment of the invention provides a fixture for polishing castings. In use, controlling the first linear slide 3 moves the second support plate 4, which in turn moves the second rotating shaft 5. This changes the distance between the two clamping plates 6, clamping and fixing the casting. Then, controlling the motor 7 drives the drive belt gear to rotate. Through the synchronous toothed belt 8, the first rotating shaft 2 rotates. Supported by the second rotating shaft 5, the two clamping plates 6 rotate the casting, facilitating polishing of different surfaces. When a large change in the distance between the two clamping plates 6 is required, the moving end of the first linear slide 3 must be able to move a sufficient distance. However, the moving distance of the moving end of the first linear slide 3 is close to the length of the first linear slide 3 itself. Therefore, compared to a design using a cylinder as the driving component, the height of the device is reduced by about half, decreasing the vertical space occupied by the device.

[0039] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a first pad, a first guide rail 9, and a first slider 10. The first pad is mounted on the first support plate 1. The first guide rail 9 is mounted on the first pad. The first slider 10 is mounted on the first guide rail 9 and is connected to the second support plate 4. The movement direction of the first slider 10 relative to the first guide rail 9 is the same as the movement direction of the moving end of the first linear slide 3, so that the first slider 10 can slide relative to the first guide rail 9 as the moving end of the first linear slide 3 moves.

[0040] In this embodiment, the first pad serves to support and elevate the first guide rail 9 and the first slider 10 to adjust their positions. The first guide rail 9 and the first slider 10 serve to guide and support, thereby improving the stability of the second support plate 4 during movement and reducing the force on the moving end of the first linear slide 3.

[0041] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a third support plate 11 and a second linear slide 12. The second linear slide 12 is mounted on the third support plate 11, and the first support plate 1 is mounted on the moving end of the second linear slide 12. The direction of movement of the moving end of the second linear slide 12 is parallel to the direction of movement of the moving end of the first linear slide 12.

[0042] In this embodiment, the third support plate 11 is used to support and mount the second linear slide 12, and the second linear slide 12 is used to support and mount the first support plate 1. In use, controlling the second linear slide 12 to operate will drive the first support plate 1 to move, which in turn will drive the clamped casting to move, thereby facilitating the grinding of different parts of the casting.

[0043] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a second pad, a second guide rail 13, and a second slider 14. The second pad is mounted on the third support plate 11. The second guide rail 13 is mounted on the second pad. The second slider 14 is mounted on the second guide rail 13 and connected to the first support plate 1. The movement direction of the second slider 14 relative to the second guide rail 13 is the same as the movement direction of the moving end of the second linear slide 12, so that the second slider 14 can slide relative to the second guide rail 13 as the moving end of the second linear slide 12 moves.

[0044] In this embodiment, the second pad serves to support and elevate the second guide rail 13 and the second slider 14 to adjust their positions. The second guide rail 13 and the second slider 14 serve as guide supports to improve the stability of the first support plate 1 during movement and reduce the force on the moving end of the second linear slide 12.

[0045] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a fourth support plate 15 and a third linear slide 16. The third linear slide 16 is mounted on the fourth support plate 15, and the third support plate 11 is mounted on the moving end of the third linear slide 16. The movement direction of the moving end of the third linear slide 16 is perpendicular to the movement direction of the moving end of the second linear slide 12.

[0046] In this embodiment, the fourth support plate 15 is used to connect to other equipment and support the installation of the third linear slide 16, which in turn supports the installation of the third support plate 11. In use, controlling the third linear slide 16 moves the third support plate 11, ultimately moving the clamped casting. Furthermore, since the movement direction of the moving end of the third linear slide 16 is perpendicular to the movement direction of the moving end of the second linear slide 12, the clamped casting can move automatically within a plane, further facilitating the grinding of different parts of the casting.

[0047] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a third pad, a third guide rail 17, and a third slider 18. The third pad is mounted on the fourth support plate 15. The third guide rail 17 is mounted on the third pad. The third slider 18 is mounted on the third guide rail 17 and connected to the third support plate 11. The movement direction of the third slider 18 relative to the third guide rail 17 is the same as the movement direction of the moving end of the third linear slide 16, so that the third slider 18 can slide relative to the third guide rail 17 as the moving end of the third linear slide 16 moves.

[0048] In this embodiment, the third pad serves to support and elevate the third guide rail 17 and the third slider 18 to adjust their positions. The third guide rail 17 and the third slider 18 serve as guide supports to improve the stability of the third support plate 11 during movement and reduce the force on the moving end of the third linear slide 16.

[0049] Optionally, combined Figure 1 and Figure 2 As shown, it also includes a first bearing housing 19 and a first angular contact ball bearing 20. The first bearing housing 19 is mounted on the first support plate 1 and sleeved on the first rotating shaft 2. The first angular contact ball bearing 20 is mounted opposite to the first bearing housing 19 and the first rotating shaft 2.

[0050] In this embodiment, the first bearing housing 19 is used to support and mount the first angular contact ball bearing 20, and to limit the position of the first angular contact ball bearing 20. The oppositely mounted first angular contact ball bearing 20 is used to support and mount the rotatable first shaft 2, bear the axial and radial forces on the first shaft 2, reduce the friction force on the first shaft 2, and improve the rotational accuracy of the first shaft 2.

[0051] Optionally, combined Figure 1 and Figure 3As shown, it also includes a second bearing housing 21 and a second angular contact ball bearing 22. The second bearing housing 21 is mounted on the second support plate 4 and sleeved on the second rotating shaft 5. The second angular contact ball bearing 22 is mounted opposite to the second bearing housing 21 and the second rotating shaft 5.

[0052] In this embodiment, the second bearing housing 21 is used to support and mount the second angular contact ball bearing 22, and to limit the movement of the second angular contact ball bearing 22. The opposingly mounted second angular contact ball bearing 22 is used to support and mount the rotatable second shaft 5, bear the axial and radial forces on the second shaft 5, reduce the frictional force on the second shaft 5, and improve the rotational accuracy of the second shaft 5.
