Problems solved by technology

[0004] (1) The existing grinding machine needs to replace different grinding accessories when grinding workpieces such as polygonal and eccentric workpieces, so as to ensure stable contact between the grinding tool and the workpiece, and the grinding efficiency is low
[0005] (2) The existing grinding machine generally grinds by driving the workpiece to rotate or the grinding wheel to rotate during the working process. During the grinding process, the direction of the force on the workpiece changes slightly, resulting in low grinding efficiency

Embodiment 1

[0046] The present invention provides polygonal special-shaped eccentric grinding device and method thereof through improvement, and the technical scheme of the present invention is:

[0047] Such as Figure 1-Figure 8 As shown, the polygonal special-shaped eccentric grinding device includes a grinding belt 6, and one side of the grinding belt 6 is supported by the first pushing mechanism 2, the outer wall support roller 11 and the second pushing mechanism 5 to form a "V"-shaped structure. , and the first pushing mechanism 2 and the second pushing mechanism 5 are arranged on the fixed clamp frame 1 and the movable clamp frame 4 respectively, and one end of the fixed clamp frame 1 and the movable clamp frame 4 is hinged, and the fixed clamp frame 1 The first telescopic cylinder 3 is connected with the movable clamp frame 4, and the first telescopic cylinder 3 is a hydraulic cylinder;

[0048]The first pushing mechanism 2 comprises several pushing strips 25 distributed equidist...

Embodiment 2

[0064] The invention also discloses a polygonal special-shaped eccentric grinding method, including the following steps:

[0065] S1: Place the workpiece between the three-jaw chuck 92 and the indenter 93, operate the three-jaw chuck 92 to clamp and position one end of the workpiece, and the second telescopic cylinder 94 stretches and pushes the lower indenter 93 to push the other end of the workpiece Keep the workpiece in the positioned state, so that the workpiece is clamped and positioned to the "V" shape structure on one side of the grinding belt 6;

[0066] S2: Control the contraction of the first telescopic cylinder 3, the first telescopic cylinder 3 pulls the movable clamp frame 4 upward with the support of the fixed clamp frame 1, because the fixed clamp frame 1 and the movable clamp frame 4 are hinged for rotation, so that the fixed clamp frame 1 and the movable clamp frame 4 are hinged. The movable clamping frame 4 can be rotated close, so that the first pushing mech...

Abstract

The invention relates to the technical field of grinding machining, in particular to a polygonal special-shaped eccentric grinding device which comprises a grinding belt. One side of the grinding belt is supported by a first pushing and pressing mechanism, an outer wall face supporting roller and a second pushing and pressing mechanism in a matched mode to form a V-shaped structure, the first pushing and pressing mechanism and the second pushing and pressing mechanism are arranged on a fixed clamping frame and a movable clamping frame respectively, one end of the fixed clamping frame is hinged to one end of the movable clamping frame, and a first telescopic cylinder is connected between the fixed clamping frame and the movable clamping frame. The first pushing and pressing mechanism comprises a plurality of pushing and pressing plate strips distributed at equal intervals, one ends of the pushing and pressing plate strips abut against the inner wall of the grinding belt, and pushing and pressing rollers are connected to the two sides of the pushing and pressing plate strips in a rolling mode correspondingly. A workpiece can be conveniently clamped through the V-shaped structure on one side of the grinding belt, through the pushing and pressing effects of the pushing and pressing plate strips, the grinding belt can be always attached to the polygonal special-shaped eccentric workpiece, replacing of different grinding tools is not needed, and the grinding work is more convenient and efficient.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a polygonal special-shaped eccentric grinding device and a method thereof. Background technique [0002] Grinding refers to the processing method of using abrasives and abrasive tools to remove excess material on the workpiece. According to the purpose and requirements of the process, there are many types of grinding processing methods. In order to meet the needs of development, the grinding technology is moving towards precision and low roughness. , Efficient, high-speed and automatic grinding direction. Grinding belongs to finishing machining in mechanical processing, with less processing volume and high precision, so it is widely used in the machinery manufacturing industry. [0003] In the prior art, there are problems as follows: [0004] (1) The existing grinding machine needs to replace different grinding accessories when grinding polygonal, irregular and eccentric work...
