preferably, the nut end face of the support bolt is an arc face correspondingly matched with the inner wall face of the pipe fitting;
preferably, the number of the supporting mechanisms positioned at the same end of the mandrel is at least three;
preferably, the support mechanisms positioned at the same end of the mandrel are divided into two groups, and a space is arranged between the two groups of support mechanisms;
preferably, the two groups of supporting mechanisms are arranged in a staggered manner.
Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has:
the utility model discloses a location frock for processing thin and long thin-walled tube spare excircle can provide the holding power for the internal face of pipe fitting through the supporting mechanism to a plurality of supporting mechanisms encircle the outer fringe face that sets up at the dabber, consequently make the holding power that the internal face of pipe fitting received more even, thereby improve the rigidity of pipe fitting, let the pipe fitting more stable in the course of working, prevent the shake sword phenomenon to appear, improve the work piece surface finish, improve machining efficiency; in addition, the whole length of the supporting mechanism can be adjusted by screwing the supporting bolt, so that the pipe fitting with different diameters can be adapted.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a mandrel; 2. a pipe fitting; 3. a support mechanism; 3.1, a support frame; 3.2, fastening a nut; 3.3, supporting the bolt.
Detailed Description
The invention will be explained in more detail by the following examples, which disclose the invention and are intended to protect all technical improvements within the scope of the invention.
The positioning tool for machining the excircle of the slender thin-wall pipe fitting, which is described in the attached figure 1, comprises a mandrel 1 and a supporting mechanism 3; the pipe fitting 2 is sleeved on the outer side of the mandrel 1, the mandrel 1 is correspondingly installed on a lathe through two centers, the two ends of the mandrel 1 can keep high concentricity by a double-center clamping method, the outer edge surfaces of the two ends of the mandrel 1 are all provided with a plurality of supporting mechanisms 3 in a surrounding mode, the pipe fitting 2 and the mandrel 1 can keep concentric by adjusting the plurality of supporting mechanisms 3 to be the same length, in addition, the supporting mechanisms 3 provide supporting force for the pipe fitting 2, the purpose of positioning the pipe fitting 2 is achieved, the rigidity of the pipe fitting 2 can be improved through the supporting mechanisms 3, the pipe fitting 2 is more stable in the machining process, the phenomenon of tool shaking is prevented, the surface smoothness of a workpiece is improved, and the machining efficiency is improved; in particular, the number of the supporting mechanisms 3 at the same end of the mandrel 1 is at least three, so that the supporting force on the inner wall of the pipe fitting 2 can be ensured to be more uniform, in addition, the supporting mechanisms 3 at the same end of the mandrel 1 are arranged into two groups, a space is arranged between the two groups of supporting mechanisms 3, and the two groups of supporting mechanisms 3 are arranged in a staggered manner, so that the supporting force of the supporting mechanisms 3 on the pipe fitting 2 is more uniform, and the supporting effect is better; the supporting mechanism 3 comprises supporting bolts 3.3, a supporting frame 3.1 and fastening nuts 3.2, the supporting frame 3.1 is correspondingly and vertically installed on the outer edge surface of the core shaft 1, the fastening nuts 3.2 are fixedly arranged on the top surface of the supporting frame 3.1, the screw column ends of the supporting bolts 3.3 are correspondingly and vertically connected with the fastening nuts 3.2 through threads, and correspondingly penetrate through the top surface of the supporting frame 3.1, the screw cap ends of the supporting bolts 3.3 are correspondingly abutted against the inner wall surface of the pipe fitting 2, the length of the bolts extending out of the supporting frame 3.1 is adjusted by screwing the supporting bolts 3.3, and finally all the supporting bolts 3.3 are adjusted to be the same length, namely, the pipe fitting 2 and the core shaft 1 are concentric, particularly, the screw cap end surfaces of the supporting bolts 3.3 are set to be arc surfaces correspondingly matched with the inner wall surface of the pipe fitting 2, and the supporting effect of the.
