Spherical valve core drilling machining device

Abstract

The invention relates to the technical field of spherical valve core drilling, discloses a spherical valve core drilling device, and solves the problems that a spherical valve core on the market is acore part of a certain type of flow valve body at present, the hole spacing precision on the spherical surface of the spherical valve core directly influences the product performance, but the cost isgenerally higher when the spherical valve core is machined on a five-axis linkage machine tool, and on the other hand, due to the fact that a drill bit is small and poor in strength when drilling is conducted on the spherical surface, the drill bit is prone to slipping when the drill bit makes contact with the spherical surface, the hole position deviates, and the hole spacing cannot meet the requirements for pattern design. The spherical valve core drilling machining device comprises a base, wherein an orientation frame is fixedly arranged at the top of the base; pitching shafts are fixedly arranged on the two sides of the orientation frame; the two pitching shafts are distributed with the axis of the orientation frame as the center; and two through holes are arranged in the base. According to the spherical valve core drilling device, the drilling requirements for pattern design of parts are met, the indexing is accurate, the reliability is high, the batch machining, assembling and disassembling are convenient, and the benchmark positioning is accurate.

Description

technical field [0001] The invention belongs to the technical field of spherical valve core drilling, in particular to a spherical valve core drilling processing device. Background technique [0002] Drilling device refers to the general term for the equipment used to process holes on solid materials. Common drilling devices include electric drills, drilling machines, etc. With the further development of processing technology, the efficiency of drilling devices has also been greatly improved. [0003] However, the spherical valve core currently on the market is the core component of a certain type of flow valve body. The accuracy of the hole spacing on the spherical surface of the spherical valve core directly affects the product performance. Generally, it is processed on a five-axis linkage machine tool, but the cost is high. On the other hand, When drilling on a spherical surface, due to the small strength of the drill bit, it is easy to slip when the drill bit touches the...

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a spherical valve core drilling processing device, which effectively solves the problem that the spherical valve core in the current market is the core component of a certain type of flow valve body, and the spherical surface of the spherical valve core The accuracy of the hole spacing directly affects the performance of the product. Generally, it is processed on a five-axis machine tool, but the cost is high. On the other hand, when drilling on a spherical surface, due to the small strength of the drill bit, it is easy to slip when the drill touches the spherical surface, making the hole position Offset occurs, and the hole spacing cannot meet the requirements of the pattern design
