Abstract
Description
Technical Field
[0001] This invention relates to a drilling and positioning fixture for shaft-type workpieces, which can be widely used in the radial drilling and positioning process of shaft-type workpieces. Background Technology
[0002] In mechanical assembly, it is often necessary to drill radial holes in shaft-type workpieces so that the shaft can be accurately positioned and reliably fixed to gears, flanges and other connecting parts by fasteners such as pins and bolts, to prevent relative sliding or rotation and ensure assembly position accuracy.
[0003] When drilling shaft-type workpieces, due to their cylindrical shape, they are prone to rolling or displacement during drilling, which is time-consuming and laborious, and can easily lead to inaccurate positioning, reduced machining accuracy, or even scrap. Summary of the Invention
[0004] The purpose of this invention is to provide a drilling positioning fixture for shaft workpieces that offers reliable workpiece clamping and positioning, improved clamping efficiency, accurate and reliable positioning, guaranteed drilling position accuracy, reduced labor intensity, good workpiece drilling quality, and high production efficiency.
[0005] To achieve the above objectives, the present invention provides a drilling and positioning fixture for shaft-type workpieces, comprising a fixture base fixedly mounted on a drilling machine base, a cover plate fastened to the top surface of the fixture base by fastening bolts, a guide drill sleeve located directly below the drill bit of the drilling machine and fastened to the cover plate by fastening screws, a positioning seat mounted on the fixture base and having an arc surface on its upper part for mounting shaft-type workpieces, a positioning frame fixedly mounted on the drilling machine base, a plurality of radial positioning bolts threaded to the positioning frame for radial positioning of the shaft-type workpieces, an axial positioning bolt threaded to the positioning frame for axial positioning of the shaft-type workpieces, and a positioning seat fastening bolt threaded to the positioning frame for fastening the positioning seat.
[0006] The present invention provides a drilling and positioning fixture for shaft-type workpieces, wherein the radial positioning bolt is used to radially fasten the workpiece and is adjusted according to the diameter of the shaft-type workpiece to be processed.
[0007] This invention provides a drilling and positioning fixture for shaft-type workpieces. The axial positioning bolts, by loosening or tightening, enable fine adjustment and locking of the axial position of the workpiece, thereby adjusting the drilling position of the shaft-type workpiece to be processed.
[0008] This invention discloses a drilling and positioning fixture for shaft-type workpieces. Its working principle is as follows: In use, the shaft-type workpiece to be processed is placed on the positioning seat, with one end abutting against the axial positioning bolt. By loosening or tightening the axial positioning bolt, the axial position of the workpiece can be finely adjusted and locked. According to the workpiece diameter, the position of the radial positioning bolt is adjusted to radially secure the workpiece from the side. A cover plate equipped with a guide drill sleeve is placed above the workpiece at the predetermined drilling position. The drilling machine is operated, and the drill bit, precisely guided by the guide drill sleeve, drills a hole in the workpiece. After processing, the radial and axial positioning bolts are loosened, and the processed workpiece can be removed.
[0009] This invention provides a drilling and positioning fixture for shaft-type workpieces. Firstly, the workpiece employs a dual positioning and clamping structure with radial and axial positioning bolts, ensuring reliable workpiece clamping and positioning and improving clamping efficiency. Secondly, the positioning seat uses an arc-shaped structure to provide arc-shaped contact positioning for the workpiece, restricting its movement in the vertical direction. Thirdly, the drill bit uses a guide drill sleeve positioning structure to provide precise drilling guidance, significantly improving the positional accuracy of drilling shaft-type workpieces. This effectively solves the radial and axial positioning problems during shaft-type workpiece drilling. Therefore, the positioning is accurate and reliable, ensuring drilling positional accuracy, reducing labor intensity, resulting in high-quality workpiece drilling and high production efficiency.
[0010] This invention provides a drilling and positioning fixture for shaft-type workpieces, ensuring that the drilling position meets assembly requirements. When the shaft-type workpiece is subsequently assembled with pins, bolts, and other components, the precisely drilled hole allows for accurate alignment and secure fixing with other parts, effectively preventing relative movement and guaranteeing the accuracy and reliability of the assembled shaft-type product. Therefore, high assembly accuracy is achieved.
[0011] This invention provides a drilling positioning fixture for shaft-type workpieces. The workpiece clamping, positioning adjustment, and disassembly processes are simple and quick, and the operation is convenient and efficient, which also greatly improves the production efficiency of drilling.
[0012] In summary, the present invention provides a drilling and positioning fixture for shaft-type workpieces, which ensures reliable workpiece clamping and positioning, improves clamping efficiency, provides accurate and reliable positioning, guarantees drilling position accuracy, reduces labor intensity, produces high-quality workpiece drilling, and increases production efficiency.
