Abstract
The utility model provides a mouth of pipe ball tight positioner that expands which belongs to welding frock technical field. This kind of mouth of pipe ball tight positioner that expands is including round pin hub connection piece, positioning pin, bloated tight cone and the tight cylinder that expands. Junction between round pin hub connection piece and positioning pin is equipped with the big 1mm of diameter of the three ball hole of placing the tight ball that expands of equipartition, the bloated tight ball of diameter ratio in ball hole. Bloated tight cone adopts fixing bolt to contact through the tip of cushion fixed connection at the piston rod, the taper surface of expand tight ball and bloated tight cone. Promote to expand tight cone when removing to the pipe fitting direction at bloated tight cylinder, the taper surface of the tight cone that expands promotes to expand tight ball and outwards removes, leans on tightly with the inner cylinder face of pipe fitting tip. This positioner adopts the bloated tight locate mode of pneumatic ball, improves the stability and the reliability of orificial positioning accuracy, mouth of pipe location, improves production efficiency and security.
Description
Technical field
This utility model relates to a kind of mouth of pipe ball swelling positioner, and it belongs to welding tooling technical field.
Background technology
In domestic automobile gas extraction system frock clamp, mouth of pipe location is typically directly connected with locating shaft and positioning sleeve with cylinder at present, this structure is when workman's piece installing, workpiece is often subjected to displacement when compressing, and the application of this state occur the problem that 1. clamping process have the risk clipping to workman's hands；2. after welding, nozzle position exceeds the margin of tolerance；3. between locating shaft and product (pipe fitting), there is gap to cause positioning inaccurate.
Summary of the invention
For the problem overcoming prior art to exist, this utility model provides a kind of mouth of pipe ball swelling positioner, this positioner should use pneumatic ball swelling to position mode, improves the positioning precision of the mouth of pipe, the stability of mouth of pipe location and reliability, improves production efficiency and safety.
The technical solution adopted in the utility model is: a kind of mouth of pipe ball swelling positioner, it includes a bearing pin contiguous block and an alignment pin, it also includes a swelling conical head and a swelling cylinder, described bearing pin contiguous block and swelling cylinder are respectively fixedly connected with the both sides at connecting plate, described alignment pin is fixedly connected on bearing pin contiguous block, junction between bearing pin contiguous block and alignment pin is provided with uniform three and places the ball hole of swelling ball, the diameter 1mm bigger than the diameter of swelling ball of ball hole；The piston of described swelling cylinder and piston rod use integral structure；Described swelling conical head uses fixing bolt to be fixedly connected on the end of piston rod through cushion block, and described swelling ball contacts with the taper surface of swelling conical head；When swelling cylinder promotes swelling conical head to move to pipe fitting direction, the taper surface of swelling conical head promotes swelling ball to be displaced outwardly exposing bearing pin contiguous block and the external cylindrical surface of alignment pin setting circle shell of column, is close to the inner cylinder face of pipe fitting (workpiece) end.
The beneficial effects of the utility model are: this mouth of pipe ball swelling positioner includes bearing pin contiguous block, alignment pin, swelling conical head and swelling cylinder.Junction between bearing pin contiguous block and alignment pin is provided with uniform three and places the ball hole of swelling ball, the diameter 1mm bigger than the diameter of swelling ball of ball hole.Swelling conical head uses fixing bolt to be fixedly connected on the end of piston rod through cushion block, and swelling ball contacts with the taper surface of swelling conical head.When swelling cylinder promotes swelling conical head to move to pipe fitting direction, the taper surface of swelling conical head promotes swelling ball to be displaced outwardly, is close to the inner cylinder face of pipe fitting end.This positioner uses pneumatic ball swelling location mode, improves the positioning precision of the mouth of pipe, the stability of mouth of pipe location and reliability, improves production efficiency and safety.

Detailed description of the invention
Fig. 1 shows the structure chart of a kind of mouth of pipe ball swelling positioner.In figure, this mouth of pipe ball swelling positioner includes bearing pin contiguous block 2, alignment pin 3, swelling conical head 4 and swelling cylinder 5.Bearing pin contiguous block 2 and swelling cylinder 5 are respectively fixedly connected with in the both sides of connecting plate 1, alignment pin 3 is fixedly connected on bearing pin contiguous block 2, junction between bearing pin contiguous block 2 and alignment pin 3 is provided with uniform three and places the ball hole of swelling ball 6, the diameter 1mm bigger than the diameter of swelling ball 6 of ball hole.The piston 5a and piston rod 5b of swelling cylinder 5 uses integral structure.Swelling conical head 4 uses fixing bolt 7 to be fixedly connected on the end of piston rod 5b through cushion block 7a, and swelling ball 6 contacts with the taper surface of swelling conical head 4.When swelling cylinder 5 promotes swelling conical head 4 to move to pipe fitting 8 direction, the taper surface of swelling conical head 4 promotes swelling ball 6 to be displaced outwardly exposing bearing pin contiguous block 2 and the external cylindrical surface of alignment pin 3 setting circle shell of column, is close to the inner cylinder face of pipe fitting 8 end.
Use technique scheme, as long as the end sleeve of pipe fitting 8 on the external cylindrical surface of bearing pin contiguous block 2 and alignment pin 3 setting circle shell of column, when starting swelling cylinder 5, swelling cylinder 5 promotes swelling conical head 4 to move to pipe fitting 8 direction, the taper surface of swelling conical head 4 promotes swelling ball 6 to be displaced outwardly, and makes the swelling of three swelling balls 6 on the inner cylinder face of pipe fitting 8 end.This swelling mode simple in construction, easy to use, and also the most reliable.
