Description

Technical Field

[0001] This utility model relates to the field of casting and forging processing, specifically to a burr removal and polishing device for casting and forging. Background Technology

[0002] Castings and forgings are metal parts manufactured through casting and forging processes, encompassing sand casting, die forging, ring forging, and other process categories.

[0003] During the processing of castings and forgings, various burrs often appear on their surfaces. Therefore, the surface needs to be polished in subsequent processing. Grinding can be done by hand-held small grinders or even by using sandpaper, but this is inefficient and risky. Therefore, existing technologies use clamps to hold the castings and forgings stably, and then use mechanical arms or other mechanisms to move the grinding mechanism to grind the outer wall of the castings and forgings. However, these clamps are generally fixed, meaning that it is inconvenient to adjust the angle of the castings and forgings after clamping them. The clamps can only be loosened and released repeatedly for subsequent operations. Moreover, the grinding mechanism can only grind within a certain range, which is limited to a certain type of casting and forging.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0021] A gear 12 is fixedly installed at the bottom end of the rotating shaft 10. An adjusting cylinder 13 is fixedly installed on the inner wall of one side of the support plate 2. A connecting frame 14 is fixedly installed at the output shaft end of the adjusting cylinder 13. A rack 15 is fixedly installed on the side wall of the connecting frame 14 facing the rotating shaft 10. The rack 15 meshes with the gear 12. The movement of the rack 15 can be controlled by the adjusting cylinder 13. The movement of the rack 15 will drive the rotating shaft 10 to rotate through the gear 12, thereby realizing the rotation adjustment of the turntable 11 at the top end of the rotating shaft 10. This can drive the clamping assembly 4 to rotate synchronously, thereby realizing the angle adjustment of the clamped castings and forgings.

[0022] A slider 8 is also provided on the top of the base plate 1, and the bottom of the rack 15 is slidably mounted on the slider 8. The slider 8 can provide relatively stable support for the rack 15 to slide.

[0023] The clamping assembly 4 includes a lifting cylinder 401 fixedly mounted on the top of the turntable 11. A horizontal bar 402 is fixedly mounted on the top of the lifting cylinder 401.

The right-angle rod 411 can swing around the hinge shaft 410 through the bottom of the right-angle rod 411. The swing of the right-angle rod 411 will drive the guide wheel 415 to slide inside the second sliding hole 413, thereby realizing the movement adjustment of the slider 406.

[0025] The output shaft of the lifting cylinder 401 passes through the middle of the horizontal bar 402, and the bottom of the right-angle rod 411 passes through the middle of the support plate 404. A lifting block 417 is fixedly installed at the end of the lifting cylinder 401. A guide post 418 is fixedly installed on the outer wall of the lifting block 417, and the guide post 418 is slidably disposed in the adjacent first sliding hole 412. The lifting cylinder 401 can drive the lifting block 417 to move up and down. The movement of the lifting block 417 will move through the guide post 418 in the first sliding hole 412, thereby pulling the bottom of the right-angle rod 411, causing the right-angle rod 411 to swing around the hinge axis 410.

[0026] A clamping groove 416 is provided on one end face of the clamping block 407. The clamping groove 416 can stably clamp the edges and corners of the casting or forging.

[0027] like Figures 7 to 9 As shown, the grinding assembly 7 includes a transverse plate 701 located on the top of the support housing 6. A vertical housing 702 is fixedly installed on the top of the transverse plate 701. A lifting plate 703 is slidably installed on the side of the vertical housing 702 facing the clamp assembly 4.

A grinding head 712 is fixedly installed at the bottom end of the grinding shaft 709. The vertical housing 702 can be adjusted horizontally by moving the transverse plate 701, which in turn changes the position of the extension arm 704 and the grinding head 712, allowing the grinding head 712 to be adjusted to adapt to the position of the casting or forging.

[0028] Combination Figure 2A first slide rail 61 is symmetrically installed around the center inside the support housing 6. A first slide block 713 is symmetrically installed around the center at the bottom of the transverse plate 701. The first slide block 713 is slidably mounted on the first slide rail 61.

A first threaded sleeve 714 is fixedly mounted at the bottom center of the transverse plate 701 and is screwed onto the outside of the first lead screw 62. By adjusting the handle 63, the first lead screw 62 is rotated. The rotation of the first lead screw 62 will drive the transverse plate 701 to move through the first threaded sleeve 714, thereby changing the position of the vertical housing 702 and the grinding head 712.

[0029] A vertically mounted second lead screw 715 is rotatably installed inside the housing 702. A symmetrically arranged second slide rail 716 is also fixedly installed inside the housing 702.

A second threaded sleeve 721 is fixedly installed in the middle of the lifting block 718, and the second threaded sleeve 721 is screwed onto the outside of the second lead screw 715. Similarly, rotating the second lead screw 715 can adjust the position of the second threaded sleeve 721, which in turn drives the lifting block 718 to adjust its height.

[0030] A guide slot 719 is provided between the lifting block 718 and the lifting plate 703, and a limiting plate 717 is provided through the guide slot 719, and the limiting plate 717 is fixedly installed on the vertical shell 702. This arrangement can ensure that the lifting plate 703 can be more stable when it is raised and lowered.

[0031] An adjusting motor 723 is mounted on the top of the outer wall of the vertical housing 702. A second driving pulley 724 is fixedly mounted on the output shaft end of the adjusting motor 723. The top end of the second lead screw 715 passes through the top of the vertical housing 702 and is fixedly mounted with a second driven pulley 722. The second driven pulley 722 and the second driving pulley 724 are connected by a second transmission belt 725. Similarly, when the adjusting motor 723 is started, the adjusting motor 723 can drive the second driven pulley 722 to rotate through the second driving pulley 724 and the second transmission belt 725, thereby realizing the rotation adjustment of the second lead screw 715.

[0032] Through the above-described solution of this utility model, the structure of this utility model is reasonable. The clamping assembly 4 can effectively clamp and fix castings and forgings of different models. The clamping assembly 4 can also be rotated and adjusted by the turntable 11 at the bottom, thereby adjusting the angle of the castings and forgings. At the same time, the grinding assembly 7 can move horizontally at the top of the support housing 6, thereby adjusting the distance between the grinding head 712 and the castings and forgings, ensuring that the grinding head 712 can adapt to the burr grinding of castings and forgings of different sizes. The adjusting motor 723 can also adjust the height of the extension arm 704, change the height of the grinding head 712, and increase the grinding range.
