Problems solved by technology

7-8 Average, the quality of positioning data needs to be further improved
9-20, poor, the reliability of the positioning result is low, and the result at this time can only be understood as a rough measurement value, which is far from the high-precision positioning result
21-50, very bad, the positioning result at this time is not recommended, the positioning error is very large
However, the existing cycloid rotary machine tools are highly specialized, and lack precision when machining parts with even polygons, end face grooves, and odd polygons.

Embodiment 1

[0073] The embodiment is basically as attached figure 1 Shown: A device for processing polygonal parts using cycloidal rotation technology, including a horizontally placed base 1 and a vertical column 2, and a bearing device 3 is installed in the opposite direction of the column 2, and the bearing device 3 includes threads from top to bottom Connected chuck 301, support platform 302 and transition plate 303, under the transition plate 303 is slidably connected with a cross-section of the “凵”-shaped sliding plate 4, the sliding plate 4 includes two vertical plates parallel to each other and placed horizontally The horizontal plate, the horizontal horizontal slide rail 5 is welded between the two vertical plates, the right side of the sliding plate 4 is electrically connected to the fourth motor 12 that controls the horizontal movement of the sliding plate 4, and the model of the fourth motor 12 is HST80ST -M02430. The front of the sliding plate 4 is connected with a shaker 13 ...

Embodiment 2

[0085] The difference between this embodiment and the first embodiment is that when the maximum radius of gyration is 43 mm, and it is required to process regular quadrilateral parts with a side length of 14 mm and an accuracy of 0.03 mm, or straight groove parts, the operator will engage the raw material on the chuck In 301, the raw material and the milling head 601 are then driven to rotate synchronously at speeds n1 and n2, respectively.

[0086] At this time, the operator adjusts according to the parameters, so that the parameters satisfy the motion trajectory equation of the cutting point p follows the following equation, where t is a reference variable, t∈[a,b], a1 is the radius of the base circle of the cycloid, R 2 is the radius of the occurrence circle, where A, B, R 1 and R 2 is a constant, t is the revolution angle of the cycloid, A is the distance from point p to the center of the circle, and B is the initial angle of the cycloid; the parameter equation is

Embodiment 3

[0091] The difference between this implementation and the above-mentioned embodiment lies in the processing of heptagonal parts. Given a round bar with a diameter of 21mm, it is required to process a heptagon with a circumcircle radius of 10mm and an accuracy of 0.01mm. Take A=12.5mm, R 1 =32mm,R 2 =16mm, B=0, α=42, the cycloid trajectory is obtained as Figure 11 As shown, the measured machining accuracy is 0.005mm, which meets the machining requirements.

Abstract

The invention discloses a method and device for processing polygonal parts using cycloidal rotation technology in the technical field of mechanical processing. , the radius of curvature at the maximum polar diameter of the cycloid is changed by modifying the distance from the cutting point to the center of the cycloid, and the convergence of the cycloid is changed in combination with the ratio of the radius of the generation circle to the radius of the base circle of the cycloid. The device includes a base placed horizontally and a vertical column. A chuck is arranged in the opposite direction of the column, a cutting module is arranged above the chuck, and a debugging module for supporting the chuck is arranged below the chuck. This technical solution changes the radius of curvature at the maximum polar diameter of the cycloid by adjusting the distance from the cutting point to the center of the circle. The precision of the fillet or chamfering process meets the processing requirements of different polygonal parts.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a method for processing polygonal parts by using the cycloid rotary separation technology. Background technique [0002] Due to the complexity of polygonal parts, domestic processing of polygonal parts is mainly processed by machine tools such as milling machines or planers. The processing process includes non-continuous movements such as idle strokes, and the production efficiency and processing accuracy are not ideal. [0003] Referring to my country's accuracy classification standard, 1 is the best, which is the most ideal positioning environment, and the positioning accuracy at this time is the best. 2-3 Very good positioning result accuracy meets most occasions that require high precision. 4-6 are good, and the positioning results at this time can meet the navigation needs of general users. 7-8 Average, the quality of positioning data needs to be ...
