Technical Field

[0001] This utility model relates to the field of bushing processing technology, specifically to an anti-deformation support device for processing the thin-walled portion of a bushing. Background Technology

[0002] A bushing is a cylindrical mechanical part that is fitted onto a rotating shaft. It is a component of a sliding bearing. Generally, the bushing is fitted with the bearing housing with an interference fit, while it is fitted with the shaft with a clearance fit. During the machining process of the bushing, it is often necessary to perform machining operations such as drilling and cutting on its thin-walled part.

[0003] However, due to the structural characteristics of the thin-walled portion of the bushing, its rigidity is low, making it susceptible to deformation under external forces during processing. This deformation not only affects the machining accuracy of the bushing, leading to non-compliant product dimensions, but may also cause cracks and other damage, reducing product quality and service life. Currently, when machining the thin-walled portion of the bushing, simple clamping devices are usually used to fix the bushing. However, these devices often cannot provide effective support for the thin-walled portion of the bushing, making it difficult to avoid deformation problems during processing.

[0004] To address this issue, the present invention provides a deformation-resistant support device for machining the thin-walled portion of a bushing, thereby solving the aforementioned problems. Utility Model Content

The outer side of the screw 34 is coated with lubricating and protective grease. The left and right sides of the slider 35 are hinged with connecting rods 36. The outer ends of the two connecting rods 36 on the same side of the left and right sides are hinged with second arc blocks 32. The four connecting rods 36 on the left and right sides form a rhombus. The curvature of the outer wall of the second arc block 32 is the same as the curvature of the inner wall of the bushing 4. The outer wall of the second arc block 32 is completely attached to the inner wall of the bushing 4. The two second arc blocks 32 are located on the horizontal diameter line of the bushing 4.

[0027] The support assembly 2 also includes an arc-shaped plate 21. The support assembly 2 includes a first arc-shaped block 22. A connecting plate 37 is fixedly installed between the bottom of the first arc-shaped block 22 and the top of the horizontal plate 31. A bushing 4 is sleeved on the outer side of the horizontal plate 31 and the first arc-shaped block 22. The outer arc of the first arc-shaped block 22 is the same as the inner arc of the bushing 4. The outer wall of the first arc-shaped block 22 is completely fitted against the inner wall of the bushing 4. The first arc-shaped block 22 is located on the vertical diameter line of the bushing 4. Movable plates 24 are fixedly installed on both the front and rear sides of the arc-shaped plate 21.

[0028] Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and all electrical components mentioned in this document are powered by external power supply lines.

[0029] Working principle: When using this device to process the thin-walled part of the bushing 4, the base plate 1 is installed on the worktable of the drilling machine. First, the bushing 4 is placed on the outside of the horizontal plate 31 and the first arc-shaped block 22, so that the outer wall of the first arc-shaped block 22 is in contact with the inner wall of the bushing 4. Then, the knob 39 is rotated, and the knob 39 drives the screw 34 to rotate through the rotating rod 38. Since the threads on both sides of the center of the screw 34 have different directions of rotation, the two sliders 35 will move relative to each other on the screw 34. The movement of the sliders 35 drives the connecting rod 36 to move, which in turn causes the second arc-shaped block 32 to move towards the inner wall of the bushing 4 until the outer wall of the second arc-shaped block 32 is completely in contact with the inner wall of the bushing 4. At this time, the screw 34 remains stable due to its own self-locking function, and the second arc-shaped block 32 provides stable support force for the bushing 4.

[0030] Next, place the arc plate 21 on the outside of the bushing 4, so that the inner wall of the arc plate 21 fits against the outer wall of the bushing 4. At the same time, let the first bolt rod 26 pass through the movable plate 24, tighten the nut 27, and fix the arc plate 21, thereby fixing it from the outer wall of the bushing 4.

[0031] During drilling, the arc plate 21 and the drilling auxiliary groove 23 on the first arc block 22 can be used for positioning to ensure drilling accuracy. After processing, loosen the nut 27, remove the arc plate 21, and rotate the knob 39 in the opposite direction to disengage the second arc block 32 from the inner wall of the bushing 4, so that the processed bushing 4 can be removed.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
