Detailed Description

The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, an auxiliary positioning tool disclosed in an embodiment of the present application is composed of a base 11, a cantilever 12, a channel 13, a sliding rod 14, a pressing plate 15, an adjusting ring 16, an elastic pad 17, a driving device 18, and the like, specifically, the base 11 is used for being placed on one side of a platform or a machine tool, the cantilever 12 is fixed on the base 11, the channel 13 is arranged in the cantilever 12, both ends of the channel 13 are open ends, and the cantilever 12 can be regarded as a pipeline.

One end of the slide 14 passes through the channel 13 and both ends thereof protrude from the channel 13. One end of the sliding rod 14 is fixed with a pressing plate 15, and the other end is used for connecting with a driving device 18, when the driving device 18 acts, the sliding rod 14 can be pulled to slide in the channel 13.

The drive unit 18 may be fixed to the base 11 or to the machine tool. In some possible implementations, the drive device 18 may use a pneumatic cylinder.

The cantilever 12 is sleeved with a plurality of adjusting rings 16, an elastic pad 17 is disposed between every two adjacent adjusting rings 16, the outer diameter of the elastic pad is larger than that of the adjusting rings 16, and in combination with a specific scene, when the driving device 18 pulls the sliding rod 14 to move, the pressing plate 15 also moves along with the movement of the sliding rod 14. During the movement, the pressure plate 15 applies a pressure to the adjusting ring 16 in contact therewith, which pressure is transmitted to the remaining adjusting rings 16 and the elastic pad 17 in sequence.

The elastic pad 17 is deformed after being squeezed, and at the moment, the maximum outer diameter of the elastic pad is enlarged, so that the workpiece sleeved on the adjusting ring 16 and the elastic pad 17 can be fixed.

The auxiliary positioning tool provided by the embodiment of the application is mainly used for fixing a pipe with a thin wall thickness, and the thin-wall pipe is fixed in a mode of applying pressure to the inner wall of the thin-wall pipe. Compared with a clamping mode, the fixing mode can avoid local deformation caused by clamping force, can also play a certain supporting role, and reduces deformation of the thin-walled tube in the processing process.

Referring to fig. 2, as a specific embodiment of the auxiliary positioning tool provided by the application, a gap adjusting ring 21 is added on the cantilever 12, and the gap adjusting ring 21 is sleeved on the cantilever 12 and located between the pressure plate 15 and the adjusting ring 16 adjacent to the pressure plate 15, and is used for adjusting the pressure applied to the adjusting ring 16.

It will be appreciated that the stroke of the slide 14 is limited and that when insufficient pressure is applied to the adjustment ring 16, the thin walled tube will slip during machining. After the clearance adjusting ring 21 is added, the stroke of the sliding rod 14 is increased, and the thin-walled tube can be fixed more stably.

The outer diameter of the pressure plate 15 and the outer diameter of the adjustment ring 16 have two cases,

first, the outer diameter of the pressure plate 15 is smaller than or equal to the outer diameter of the adjusting ring 16, in this case, the thin-walled tube can be directly sleeved on the elastic pad 17, but when the difference between the outer diameter of the pressure plate 15 and the outer diameter of the adjusting ring 16 is large, the elastic pad 17 may not deform enough.

Secondly, the outer diameter of the pressure plate 15 is larger than that of the adjusting ring 16, in this case, when fixing the thin-walled tube, the pressure plate 15 needs to be detached from the sliding rod 14, which has an advantage of improving the deformation of the elastic pad 17.

When the pressure plate 15 is detachably connected with the sliding rod 14, there are several connection modes,

first, the screw connection, the outer wall of one end of the slide bar 14 is provided with screw threads, the press plate 15 is provided with a threaded hole, and the press plate 15 is screwed on the slide bar 14.

Secondly, the slide bar 14 is connected with a bolt, a threaded hole is formed in the slide bar 14, a through hole is formed in the pressing plate 15, one end of the bolt penetrates through the through hole of the pressing plate 15 and then is connected to the slide bar 14, and the pressing plate 15 is pressed on the slide bar 14.

Referring to fig. 3, as a specific embodiment of the auxiliary positioning tool provided in the application, a length adjusting ring 22 is further added to the cantilever 12, and the length adjusting ring 22 is located between the base 11 and the adjusting ring 16 adjacent to the base 11, and is used for adjusting the number of the pressing plates 15 and the adjusting rings 16 on the cantilever 12.

It will be appreciated that the stroke of the slide 14 is limited and that when the length of the thin walled tube is short, the need for an excessive number of adjustment rings 16 and pads 17 is eliminated, because the excessive number of pads 17 will disperse the pressure applied by the pressure plate 15, resulting in insufficient deformation of the pads 17, and the additional length adjustment ring 22 will allow the removal of a portion of the excess pressure plate 15 and adjustment ring 16.

The length adjusting ring 22 is further provided with an adjusting bolt 23, one end of the adjusting bolt 23 can be abutted to the cantilever 12 to fix the length adjusting ring 22, that is, the distance between the length adjusting ring 22 and the base 11 can be adjusted, and more use requirements can be met.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
