Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, specifically to a device for polishing the surface of a fixed ring. Background Technology

[0002] As a key mechanical component, the retaining ring plays an important role in many fields. Its core function is to fix, support, position, and protect related components or work objects, ensuring the stability, accuracy, and safety of equipment operation. In traditional polishing processes, the surface treatment of retaining rings often relies on manual operation or simple mechanical polishing equipment, which is not only inefficient but also results in unstable product quality. Furthermore, common mechanical polishing equipment requires changing different fixing modules when polishing the inner and outer arc surfaces of the retaining ring, which is cumbersome and inefficient. Therefore, we propose a surface polishing device for retaining rings. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, this utility model is a surface polishing device for a fixed ring, including a worktable 1, a lifting bracket 2 fixedly connected to the worktable 1, an adjustable polishing component 3 provided on the lifting bracket 2, and an internal fixing mechanism 4 provided on the worktable 1; the internal fixing mechanism 4 includes a cylinder 41 and an annular plate 42, the cylinder 41 is installed at the bottom of the worktable 1, the movable end of the cylinder 41 passes through the worktable 1 and is fixedly connected to a central rod 43, one end of the central rod 43 is fixedly connected to a frustum 44, the bottom of the annular plate 42 is fixedly connected to a support rod 45, one end of the support rod 45 is fixedly connected to the worktable 1, and the annular plate 42 is provided with a sliding groove 46, and there are four support rods 45 and four sliding grooves 46.

[0022] A limiting ring 47 is fixedly connected to the annular plate 42. A limiting groove 48 is provided on the limiting ring 47. There are four limiting grooves 48, and each of the four limiting grooves 48 corresponds to a sliding groove 46. The frustum 44 is slidably connected to the inner side of the annular plate 42 and the second limiting ring 47.

[0023] The limiting ring 47 is provided with a clamping component 49. There are four clamping components 49. Each clamping component 49 includes an L-shaped clamping plate 491 and a spring 492. The L-shaped clamping plate 491 is provided with a push groove 493. One end of the spring 492 is fixedly connected to the push groove 493.

[0024] The other end of the spring 492 is fixedly connected to the slide groove 46, and the L-shaped clamp 491 is slidably connected to the slide groove 46, the frustum 44 and the limiting groove 48 respectively.

[0025] The cross-section of the frustum 44 is trapezoidal. The diameter of the inner circle of the annular plate 42 and the limiting ring 47 is equal to the diameter of the bottom circle of the frustum 44. The contact surface between the L-shaped clamp 491 and the frustum 44 is an arc surface, which matches the arc surface of the frustum 44. The spring 492 is a compression spring.

[0026] The cylinder 41 pushes the round platform 44 to make the L-shaped clamping plate 491 slide along the slide groove 46 and clamp and fix the fixing ring. By fixing the workpiece from the inner arc surface, the outer arc surface of the fixing ring can be polished by cooperating with the adjustable grinding component 3.

[0027] An external fixing mechanism 5 is provided on the central rod 43. The external fixing mechanism 5 includes an L-shaped connecting rod 51 and a push ring 52. There are four L-shaped connecting rods 51. One end of each of the four L-shaped connecting rods 51 is rotatably connected to the worktable 1. The push ring 52 is sleeved on the central rod 43 and is slidably connected to the central rod 43.

[0028] A push rod 53 is rotatably connected to the middle of the L-shaped connecting rod 51. One end of the push rod 53 is rotatably connected to the top of the push ring 52, and the other end of the L-shaped connecting rod 51 is rotatably connected to a rotating wheel 54. Two rotating wheels 54 are symmetrically arranged.

[0029] The push rod 53 has a groove at one end near the L-shaped connecting rod 51, and the L-shaped connecting rod 51 is rotatably connected in the groove. The length of the groove limits the rotation range of the L-shaped connecting rod 51.

[0030] By pulling down the push ring 52, the push rod 53 drives the L-shaped connecting rod 51 to move closer to the push ring 52, which in turn drives the rotating wheel 54 to clamp and fix the fixed ring, thereby achieving the purpose of fixing the workpiece from the outer arc surface and then polishing the inner arc surface of the fixed ring.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] The working principle of this utility model is as follows: The extension of the movable end of the cylinder 41 causes the central rod 43 to push the frustum 44 upward, which in turn pushes the four L-shaped clamps to move outward along the slide groove 46 and clamp the fixing ring. The spring 492 is compressed and contracts. At the same time, the push ring 52 moves upward, causing the push rod 53 to push the L-shaped connecting rod 51 to rotate and drive the rotating wheel 54 to move outward. The fixing ring is fixed from the inner arc surface. When the movable end of the cylinder 41 shortens, the central rod 43 moves downward. The elastic force of the spring 492 pushes the four L-shaped clamps 491 to move towards the center and loosens the fixing ring. At the same time, the push ring 52 moves downward, causing the push rod 53 to drive the L-shaped connecting rod to rotate and drive the rotating wheel 54 to move inward. The fixing ring is fixed from the outer arc surface.
