Description

Technical Field

[0001] The utility model relates to the technical field of shaft parts processing, in particular to a radial drilling fixture for shaft parts. Background Art

[0002] When machining radial blind holes or through holes in the outer wall of shaft parts, a specific fixture is usually required to stabilize the parts. For example, patent number CN201821646929.1 discloses a drilling device for such radial hole machining. The device mainly includes a support base and a positioning assembly. The positioning assembly is composed of a positioning bracket and a positioning member. The support base has a placement area for the shaft to be machined; the positioning member has a portion that facilitates drilling operations. The positioning bracket is equipped with a fixing component, and the positioning member is used to fix the shaft to be machined to the support base.

[0003] However, this single-locator design may not be effective when processing long shaft parts, as it is difficult for a single locator to fully secure the entire shaft. In addition, during the drilling process, shaft parts may be affected by radial forces, which may cause the part to bend or deform. Utility Model Content

[0039] Specifically, as Figure 3 shown in the figure, the driving assembly includes: a slide rod 8 is fixedly connected to the slider 5. A chute 901 which is slidably fitted with the corresponding slide rod 8 is formed in the lifting plate 9. The chute 901 in the middle of the lifting plate 9 is arranged vertically, and the chutes 901 on both sides of the lifting plate 9 are arranged in an inverted V shape. Guide blocks 12 are fixedly connected to both sides of the bottom of the lifting plate 9. A sliding seat 13 is fixedly connected to the central position of the bottom of the lifting plate 9.
