Description

Technical Field

[0001] This utility model relates to the field of parts processing, and in particular to a blade surface grinding and polishing system. Background Technology

[0002] Currently, my country still relies on traditional manual grinding and polishing methods for blade production, which are time-consuming, have low capacity, and produce low precision. Manual grinding also suffers from poor quality control and high labor intensity. These problems result in low precision, low capacity, and insufficient performance in my country's blade production, severely hindering the industry's development. Compared to traditional processing methods, using industrial robots combined with automatic belt sanders for blade grinding and polishing offers advantages such as strong versatility, easy expansion, high flexibility, and low cost, making it an advanced form of blade processing.

[0003] In addition, existing blade grinding often uses two parallel grinding systems with the same drive to grind the blade surface based on the grinding curvature. Since the grinding power comes from the same active power, the sanding belt, as a belt structure, is difficult to avoid slippage, resulting in different efficiencies between the two blades during continuous grinding, which affects the production cycle.

[0004] Based on the above problems, a blade surface grinding and polishing system is needed to solve them. Utility Model Content

[0005] This invention addresses the problem that existing blade grinding systems often use two parallel grinding systems with the same drive based on the grinding curvature. Since the grinding power comes from the same active power source, the abrasive belt, being a belt structure, inevitably slips, leading to different efficiencies between the two blades during continuous grinding and affecting the production cycle. This invention provides a blade grinding and polishing system that solves the above problems by using the same abrasive belt to grind adjacent workstations.

[0006] This invention provides a blade surface polishing system, including a guide rod, a support, a drive wheel, a pair of driven wheels, an adjusting device, a polishing device assembly, and a sanding belt. The support is a vertically arranged plate structure. The guide rod, drive wheel, driven wheel, adjusting device, and polishing device assembly are arranged in a ring on the support. Each of these components is rotatable relative to the support, with its rotation axis perpendicular to the support surface. The sanding belt rotates counterclockwise twice around the drive wheel, driven wheel, adjusting device, and polishing device assembly. The adjusting device makes point contact with the sanding belt, and this contact point can move in a circular motion on the support plane. In its naturally taut state, the sanding belt intersects the circle of the contact point. The polishing device assembly includes a fixed polishing head and a rotating polishing head. Both the fixed and rotating polishing head working ends are located outside the vertical edge of the support. The fixed polishing head's working end contacts the sanding belt with static friction, while the rotating polishing head's working end contacts the sanding belt with sliding friction.

[0007] The guide rod is a rod structure with a limit rod at one end. One end of the guide rod is fixedly connected to a bracket, and the other end is fixedly connected to a limit rod, which is vertically positioned.

[0008] With the sanding belt moving in the forward direction, the intersection of the vertical projections of the two sanding belts is located in the opposite direction of the vertical position of the guide rod. The two sanding belts in the same longitudinal position, one of which goes around the upper surface of the guide rod and is located inside the limiting rod, and the other sanding belt is directly connected to the guide rod and the polishing device assembly.

[0009] In a preferred embodiment of the blade polishing system described in this utility model, the adjustment mechanism includes several support rods, a number of support wheels equal to the number of support rods, several rotating shafts, and a positioning damper. The rotating shafts are vertically fixed on the support plate. The two ends of the support rods are respectively hinged to the rotating shafts and the support wheels. The width of the end hinged to the rotating shaft is greater than the width of the end hinged to the support wheel, and the width between the two ends is smoothly transitioned. The positioning damper is set on one radial side of the rotating shaft. The working end of the positioning damper pushes out toward the axis of the rotating shaft and contacts the support rod hinged outside the rotating shaft.

[0010] The blade polishing system of this utility model, in a preferred embodiment, includes a polishing device assembly comprising a fixed polishing head, a rotating polishing head, two support columns, and four tensioning wheels. The fixed polishing head is a plate structure, and the rotating polishing head is a roller structure. Both the fixed and rotating polishing heads are mounted at one end of the support columns, which extend beyond the side line of the support frame. The tensioning wheels are mounted on both sides of the mounting end of the support columns, symmetrically arranged on the surface of the support frame with the axis of the support columns as the center of symmetry. Two rings of sanding belt are respectively mounted on the surface of the fixed and rotating polishing heads and tightened by the tensioning wheels.

[0011] The beneficial effects of this utility model are as follows:

[0012] This device uses a single abrasive belt, guided by a guide rod, to spatially adjust the wrapped abrasive belt to prevent contact, enabling simultaneous multi-station processing. This allows workpieces processed by abrasive belts, a processing method inherently involving some efficiency loss, to be stably processed within the same production cycle, avoiding station downtime. Simultaneously, through dynamic and static friction at the processing ends, different processing efficiencies are achieved at each end. Attached Figure Description
