specific Embodiment approach 1

[0023] Specific implementation mode one: combine Figure 1-9 Description of this embodiment, a special clamp for drilling the end face of a cylindrical body, which includes a clamp main body 1, a drill sleeve 2 and a screw 3, the clamp main body 1 is a rectangular structure, and the clamp main body 1 is vertically arranged from top to bottom. There are installation holes 11 and positioning deep grooves 12 in the direct opening. The drill bushing 2 is installed in the installation holes 11 and has an interference fit with the installation holes 11. The positioning deep grooves 12 have a flat bottom 12-1 and two side walls An arc-shaped through groove, the bottom of the groove 12-1 is set horizontally, the central axis of the mounting hole 11 is set vertically, and the clamp body 1 is also provided with a long hole 13, the cross section of the long hole 13 Waist-shaped, the center line of symmetry of the elongated hole 13 is set horizontally from front to back, the upper side wa...

specific Embodiment approach 2

[0025] Specific implementation mode two: combination Figure 1~5 To describe this embodiment, the central axis of the threaded hole 14 , the symmetrical central line of the elongated hole 13 and the central axis of the mounting hole 11 are located in the same vertical plane. Such a design ensures the assembly accuracy, and further ensures the positional accuracy and dimensional accuracy of the processed positioning holes 101 . Other compositions and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0026] Specific implementation mode three: combination Figure 1~5 To describe this embodiment, the wall thickness of the cylindrical workpiece 100 is smaller than the distance between the two side walls of the positioning deep groove 12 . This design makes it easy to assemble when drilling. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention provides a cylinder end face drilling special fixture and belongs to the technical field of machining. Through the cylinder end face drilling special fixture, the problems that the requirements for quantity production cannot be met, the machining precision is low and the product qualified rate is low when a locating hole is drilled in one end face of a cylinder workpiece through a scribing drilling method in the prior art are solved. A mounting hole and a locating deep slot are vertically formed in a fixture body from top to bottom. A drill bush is penetrated into the mounting hole. The locating deep slot is an arc-shaped slot. The slot bottom is horizontally arranged. The fixture body is provided with a long hole. The symmetrical center line of the long hole is horizontallyarranged from front to back. The upper and lower sidewalls of the long hole communicate with the mounting hole and the slot bottom of the locating deep slot correspondingly. A threaded hole is horizontally formed in the front portion of the fixture body. The threaded hole communicates with the front sidewall of the locating deep slot. The sidewall of the workpiece is inserted in the locating deepslot. The vertical distance from the center axis of the mounting hole to the rear sidewall of the locating deep slot is equal to the distance from the locating hole of the cylinder workpiece to the edge of an inner hole of the cylinder workpiece. The cylinder end face drilling special fixture is used for drilling of the end face of the cylinder workpiece.

Description

technical field [0001] The invention relates to a fixture, in particular to a special fixture for drilling a cylindrical end face, and belongs to the technical field of mechanical processing. Background technique [0002] A cylindrical workpiece 100 has a structure such as Figure 8 and Figure 9 As shown, there is a positioning hole 101 on one end surface of the workpiece, and the distance between the centerline of the positioning hole 101 and the centerline of the inner hole of the workpiece is required to be relatively high. The positioning hole plays a positioning role when the product is assembled. If the positioning hole is processed by the method of cross-drilling, the production efficiency is low and cannot meet the needs of mass production. Moreover, the processing accuracy of the workpiece is low, and the product qualification rate is low, which affects product assembly. Contents of the invention [0003] The present invention aims to solve the problems that t...
