Embodiment Construction

[0016] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] This embodiment proposes a peripheral hole drilling and clamping positioning tool, its structure is shown in Figure 2, mainly including a V-shaped base 1, a bottom plate 10, a pin 7, a positioning block 8, a pin shaft 11, a nut 12, and a cover plate 2. Column 3, stud 13, lock nut 4 and spring washer 5.

[0018] The V-shaped base 1 is processed with a V-shaped groove running through the length direction of the base. The bottom of the V-shaped groove has a square groove structure, and the two sides of the V-shaped groove are processed with a first pin hole and a second pin hole opposite to each other.

[0019] After the V-shaped base 1 is aligned, it is fixed on the machine tool table through the pressure plate. Th...

Abstract

The invention provides a circumferential hole drilling, clamping and positioning tool. The circumferential hole drilling, clamping and positioning tool comprises a V-shaped base, a bottom plate, a pin, a positioning block, a pin shaft, a nut, a cover plate, a stand column, a stud, a locking nut and a spring washer. The tool is simple in structure, convenient to assemble and capable of achieving rapid clamping and disassembling of parts. The positioning block at the end part of the tool can realize quick axial positioning, and a jackscrew hole is processed when the positioning pin is dismounted; after the positioning pin is installed, the positioning pin is matched with the jackscrew hole to achieve circumferential positioning of the part, and the cover plate can be rapidly pressed and loosened so as to achieve rapid clamping and disassembling of the part. By means of the clamping and positioning tool, rapid machining of circumferential holes of shaft parts can be achieved, the hole machining requirement can be met in batch production, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a clamping and positioning tool suitable for drilling peripheral holes of wheel shaft parts. Background technique [0002] When the CNC vertical drilling machine drills the circumferential hole of the wheel shaft parts, the dimensional tolerance of the distance between the top screw hole and the end face of the wheel shaft parts for positioning is ±0.05mm, and the center line of the top screw hole and the center line of the oil passage hole are a plane and pass through the center of rotation of the wheel shaft , the part structure is as figure 1 shown. In order to process the circumferential hole of the wheel shaft part, it is necessary to mark the part on the part in advance, and then process according to the marked position, the processing efficiency is low, and the quality consistency is poor. Contents of the invention [0003] (1) Technical probl...
