Problems solved by technology

[0004] In view of the above prior art, after clamping the three-way pipe fitting on the chuck of the garage, it is necessary to correct the orientation of the end surface to be processed. The above correction process takes up a lot of time during the processing of the three-way pipe fitting. It is the main reason for the low processing efficiency of the end face of the three-way pipe fittings. The invention provides a clamping device for pipe fittings processing

Embodiment 1

[0034] Such as Figure 1 to Figure 4 As shown, a clamping device for pipe fittings processing includes a fixed seat 1, a workpiece seat 4 and a pressing block 7;

[0035] One end of the fixed seat 1 is used for the fixed connection between the fixture and the lathe chuck, and the other end of the fixed seat 1 is provided with a locking hole 2, the locking hole 2 is a circular through hole, and also includes a Three pin holes 9, the pin holes 9 are distributed around the locking hole 2, and the distance between the three pin holes 9 and the locking hole 2 is equal;

[0036] The bottom end of the workpiece seat 4 is provided with an internally threaded hole and a positioning pin 5, and also includes a locking bolt 3 pierced in the locking hole 2, and the workpiece seat 4 is locked by a threaded connection with the internally threaded hole. The bolt 3 is fixed on the fixed seat 1, and the positioning pin 5 is embedded in any one of the pin holes 9, and the upper end surface of t...

Embodiment 2

[0047] The present embodiment is further limited on the basis of embodiment 1, as Figure 1 to Figure 4 As shown, as a specific implementation form of the fixing seat 1, one end of the fixing seat 1 is cylindrical, the other end of the fixing seat 1 is flat, and the locking hole 2 and the pin hole 9 are all located in the fixing seat. 1 One end in the shape of a flat plate. In this mechanism, the cylindrical end of the fixing seat 1 is used for fixing the fixture on the lathe, and the fixing of the fixture on the lathe can be completed by clamping the fixing seat 1 with a chuck; the fixing seat 1 is in the shape of a flat plate One end of the clamp can make the workpiece seat 4 and the fixed seat 1 have a larger contact area, which is beneficial to optimize the force on the mating surfaces of the two when the fixture is working. Furthermore, one end of the flat plate needs to be lower than the one end of the cylinder, so that after the workpiece seat 4 is fixed on the fixed s...

Embodiment 3

[0052] This embodiment is further limited on the basis of any one of the above embodiments, such as Figure 1 to Figure 4 As shown, in order to facilitate the separation of the positioning pin 5 from the corresponding pin hole 9 and facilitate the processing efficiency of the end surface of the three-way pipe fitting when using this fixture, the depth of the pin hole 9 is between 3 and 5 mm.

Abstract

The invention discloses a clamping device for processing pipe fittings, which includes a fixed seat, a workpiece seat and a pressing block; one end of the fixed seat is used for fixed connection between the fixture and the lathe chuck, and the other end of the fixed seat is provided with a locking device. holes, also including three pin holes; the workpiece seat is provided with an internal thread hole and a positioning pin, and also includes a locking bolt, and the positioning pin is embedded in any pin hole, and the upper end surface of the workpiece seat There is an accommodating groove for clamping three-way pipe fittings; the pressing block is fixed on the workpiece seat, and the pressing block is located above the accommodating groove, and the distance between the pressing block and the workpiece seat is adjustable; the pressing block It is used to apply compressive stress to the three-way pipe fittings and fix the three-way pipe fittings on the fixture; the fixed seat is a two-section combined structure, and the height difference between the two parts forming the fixed seat is linearly adjustable. The fixture is beneficial to improve the processing efficiency of the connecting pipe end face of the tee pipe fitting, and is suitable for processing the end faces of the tee pipe fittings of different types.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a clamping device for processing pipe fittings. Background technique [0002] Tee pipe fittings are used in pipe branches and are widely used in fluid delivery pipelines. The three-way pipe fittings made of seamless steel pipes are usually produced by hydraulic bulging and hot pressing. The three end faces of the processed pipe fitting blanks generally need to be turned by lathes. In the prior art, the three end faces of the tee pipe need to be turned in turn. In this way, in the process of end face switching, it is necessary to clamp the three-way pipe fitting three times. [0003] In the above clamping process, in order to make each end face perpendicular to the joint axis corresponding to each end face, after clamping the three-way pipe fitting on the chuck of the garage, it is necessary to correct the orientation of the end face to be processed. The above corr...
