Description
Technical Field
The invention relates to a positioning fixture, in particular to a positioning device for machining a cylindrical mechanical part.
Background
Barrel-type machine part is after through crooked or other preliminary machining shaping, follow-up processing need adopt positioning fixture fixed back to process again, but current positioning fixture is fairly simple, it not only destroys work piece excircle surface easily in the use, moreover because the relatively poor position precision that leads to the saw-off of its stability is lower, thereby the qualification rate of work piece has been influenced, how to provide one kind and to enable the work piece fixed back stability higher, the positioning fixture of the work piece qualification rate after guaranteeing to process is the problem that this trade needs to solve urgently.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a positioning device for processing a cylindrical mechanical part, which can effectively solve the problems.
In order to achieve the purpose, the invention adopts the technical scheme that: a positioning device for processing a cylindrical mechanical part comprises a base, a rotary fixing frame, a first bearing, a rotary disk, a positioning rod, a rotating shaft, a bracket and a second bearing,
the rotary fixing frame is fixed on the upper part of one end of the base, the support is fixed on the upper part of the other end of the base, the rotating shaft is positioned between the rotary fixing frame and the support, and two ends of the rotating shaft respectively penetrate through the rotary fixing frame and the support; one end of the rotating shaft is fixed with the rotary fixing frame through a first fixing nut, and the other end of the rotating shaft is fixed with the bracket through a second fixing nut; the rotating disc is arranged on the rotating shaft through a first bearing and is close to the rotating fixing frame; the three positioning rods are distributed on one side of the rotating disc in a delta shape and are arranged in parallel with the rotating shaft; the second bearing is arranged on the rotating shaft and is close to the bracket; and an auxiliary tray is arranged on the second bearing, is of a hollow structure and can enable the cylindrical mechanical parts to pass through.
Further, the rotating disc is made of alloy materials.
Furthermore, the rotary fixing frame and the bracket are respectively welded with the base.
The invention combines the base, the rotary fixing frame, the first bearing, the rotary disc, the positioning rod, the rotating shaft, the bracket and the second bearing, so that the workpiece has higher stability after being fixed, and the qualified rate of the processed workpiece is ensured.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure: 1. the device comprises a base, 2, a rotary fixing frame, 3, a first fixing nut, 4, a first bearing, 5, a rotary disc, 6, a positioning rod, 7, a rotating shaft, 8, a support, 9, a second bearing, 10 and a second fixing nut.
Detailed Description
The present invention will be further explained below.
As shown in figure 1, the invention comprises a base 1, a rotary fixing frame 2, a first bearing 4, a rotary disk 5, a positioning rod 6, a rotating shaft 7, a bracket 8 and a second bearing 9,
the rotary fixing frame 2 is fixed on the upper part of one end of the base 1, the support 8 is fixed on the upper part of the other end of the base 1, the rotating shaft 7 is positioned between the rotary fixing frame 2 and the support 8, and two ends of the rotating shaft 7 respectively penetrate through the rotary fixing frame 2 and the support 8; one end of the rotating shaft 7 is fixed with the rotary fixing frame 2 through a first fixing nut 3, and the other end of the rotating shaft 7 is fixed with the bracket 8 through a second fixing nut 3; the rotating disc 5 is arranged on the rotating shaft 7 through a first bearing 4 and is close to the rotating fixing frame 2; the number of the positioning rods 6 is three, the three positioning rods 6 are distributed on one side of the rotating disc 5 in a delta shape, and the positioning rods 6 are arranged in parallel with the rotating shaft 7; the second bearing 9 is arranged on the rotating shaft 7 and is close to the bracket 8; an auxiliary tray is arranged on the second bearing 9, and the auxiliary tray is of a hollow structure and can enable the cylindrical mechanical parts to pass through.
Further, the rotating disc 5 is made of alloy material.
Further, the rotary fixing frame 2 and the bracket 8 are respectively welded with the base 1.
When the auxiliary support device works, a cylindrical mechanical part to be processed is arranged on the three positioning rods 6 after passing through the bracket 8 and the auxiliary tray, so that the cylindrical mechanical part is fixed by the positioning rods 6, and then the auxiliary tray can play an auxiliary support role if the cylindrical mechanical part is longer; at the moment, a worker can process the surface of the cylindrical mechanical part from the upper part, after partial processing is finished, the worker drives the rotating disc 5, the rotating disc 5 starts to rotate relative to the rotating shaft 7 under the rotating action of the first bearing 4, and then the three positioning rods 6 drive the cylindrical mechanical part to rotate, so that the unprocessed surface stops rotating to the upper part; at this time, the worker can process the part of the surface from above, and the rotation process is repeated after the processing is completed until the surface processing of the whole barrel-shaped mechanical part is completed.
