Embodiment Construction

[0018] like figure 1 , figure 2 , image 3 As shown, the indexing head orifice plate 3 has 54 indexing holes, and the 360° is divided into 2160 parts on average by using the 54 indexing holes, and the minimum indexing is 10' for each hole rotated. Orifice plate main body 1 profile is arc, has 10 holes on it, and a big hole is the pin hole that is used to insert taper pin 2, and the hole diameter of 9 diameter 3mm is consistent with the hole diameter on indexing head hole plate 3. The diameter of the indexing circle of the ten holes is consistent with the diameter of the indexing circle of 54 holes on the indexing head orifice plate 3 . The angular interval of the ten holes is 1.1 times the angular interval of the holes on the orifice plate of the dividing head. That is 360° / 54×1.1=7°20′, since the transmission ratio of the indexing head is 1:40, the angle of the indexing head after turning through a hole on the orifice plate 1 is 7°20′ / 40 = 11'. Turn a hole on the hole p...

Abstract

The invention discloses a hole plate structure capable of improving the division capacity of a dividing head. The hole plate structure comprises a standard dividing head hole disc, an arc-shaped holeplate and conical plug pins; the arc-shaped hole plates and the dividing head hole disc are concentric, the arc-shaped hole plate is provided with a plurality of subdividing holes, and pin holes withthe hole diameter being greater than the hole diameter of the subdividing holes are formed in one ends of the arc-shaped hole plate. The diameter of the multiple subdividing holes is consistent with that of dividing holes in the dividing head hole disc, the pin holes are included, the dividing circle diameter of a plurality of holes in the arc-shaped hole plate is consistent with that of the dividing holes, and the arc-shaped hole plate can be fixed into any dividing hole through the corresponding conical plug pin. The hole plate structure is simple in structure, easy to use and high in precision, and the division capacity of the dividing head can be greatly improved.

Description

technical field [0001] The invention relates to an orifice plate structure capable of improving the indexing ability of an indexing head and its application method. Background technique [0002] In mechanical processing, the indexing function of the dividing head is often used to mark the line, or to assist in the processing of some shaft parts or parts that need to be rotated on the machine tool. The dividing head is to divide 360° into several parts on average. For example, using a hole plate with 54 holes a week to divide, it divides 360° into 2160 parts on average, and the minimum graduation is 10' for each hole rotated. The dividing head cannot cover all angles, and the dividing ability is limited. However, some parts need to be accurate to 1′ at the angular interval during processing, and the ability of the dividing head cannot be achieved at this time. If you want to complete the processing of such parts, you can only use the dividing head to adopt other complex ind...
