Device for machining semi-arc long groove

Abstract

The invention discloses a device for machining a semi-arc long groove. The device comprises a supporting plate, a first rotary rod, a second rotary rod, a slide block and a planer tool, wherein the first rotary rod is connected with the supporting plate through screw threads; a first threaded through hole is formed in the supporting plate in the longitudinal direction; a through hole is formed in the supporting plate in the transverse direction; a first slide groove is formed in the lower part of the supporting plate; a slide block is positioned in the slide groove; a threaded post is arranged in the first slide groove; a second slide groove and a second threaded through hole are formed in the slide block in the longitudinal direction; the width value of the second slide groove is greater than the outer diameter value of a threaded rod; the planer tool is detachably connected with the first rotary rod; the first rotary rod is a threaded rod; a first bevel gear is arranged on the bottom part of the first rotary rod; a second bevel gear is arranged on the end part of the second rotary rod; the first rotary rod is meshed with the second rotary rod by the gears; a locking nut is arranged on the threaded post. The defects of complex mounting and high manufacturing cost caused when the semi-arc long groove of a current workpiece is required to be processed by mounting a milling cutter with a special shape on a milling machine are overcome.

Description

technical field

[0001] The invention relates to the field of devices for processing semicircular long grooves, in particular to a device for processing semicircular long grooves. Background technique

[0002] Plastic products are usually injection molded by an injection molding machine, but the shape of the template on the injection molding machine determines the shape of the product. For semi-arc-shaped long strip products, the corresponding formwork needs to have a semi-arc-shaped long groove. However, in actual production, the mold for machining semicircular arc-shaped long grooves requires special-shaped milling cutters to be processed on a milling machine. However, milling cutters with different specifications and special shapes are required for semicircular long grooves with different radii. However, the use of milling machines to process semicircular arc-shaped long grooves has the disadvantages of complicated installation and high manufacturing costs. Contents of...
