Furthermore, three universal balls for supporting the end sockets are arranged on the edge of the end socket placing seat.

Furthermore, three electromagnetic chucks for adsorbing and fixing the seal heads are arranged on the seal head placing seat and positioned at the edge of the seal head placing seat.

Furthermore, the rollers of the aligning device are driven by the same motor to move towards the center of the head placing seat.

Furthermore, the number of the idler wheels on any one of the aligning devices is two, and the centers of all the idler wheels are concentric with the center of the seal head placing seat.

Furthermore, a rotary table which supports and drives the seal head to rotate is arranged on the seal head placing seat.

Compared with the prior art, the invention has the advantages that:

the head of the automatic alignment cutting device is supported by three universal balls on the circular head placing seat, the adjustment of the head is easily realized by the alignment device driving idler wheels, the alignment work can be automatically completed when each infrared control switch contacts the surface of the head, the full automation of the alignment work is realized, and the efficiency of alignment cutting is greatly improved.

The present invention will be described in further detail below with reference to the accompanying drawings.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

As shown in fig. 1, the embodiment of the invention discloses an automatic aligning and trimming machine for end sockets of pressure vessels, which comprises an end socket placing seat 1, an aligning device 2 and a trimming device 3, wherein the aligning device 2 and the trimming device 3 are arranged on the outer edge of the end socket placing seat 1, a roller 4 and an infrared control switch 5 which can move towards the center of the end socket placing seat 1 are arranged on the aligning device 2, the center of the roller 4 can form a circle concentric with the end socket placing seat 1, and when the infrared control switch 5 is in contact with an end socket 6, the roller 4 which synchronously moves towards the center of the end socket placing seat 1 stops.

The operating principle of the device is that three aligning devices 2 which are provided with rollers 4 and are arranged on the periphery of the end socket 6 drive the rollers 4 to synchronously move at a constant speed towards the direction of the circle center, wherein the rollers 4 are always on a circular arc line, the three rollers 4 are all provided with infrared control switches 5, when the three rollers 4 all touch the surface of the end socket 6, the lamps of the infrared control switches 5 are all on, the rollers 4 are automatically closed to move at the same time, the automatic alignment of the end socket 6 is completed, and then the edge cutting is started. The ovality error of the 700 seal heads 6 finished in the mode is controlled within +/-1.5 mm, and the gap between the profiling sample plates is controlled within 2mm, so that the efficiency of aligning and cutting edges is improved, and the processing quality is improved.

In this embodiment, the head placing seat 1 is provided with three universal balls 7 for supporting the head 6 at the edge thereof, so that friction can be reduced, and the wear of the surface of the head 6 can be conveniently aligned.

In this embodiment, the head is placed and is located its edge on 1 and be provided with three electromagnet 8 that are used for adsorbing fixed head 6, after accomplishing the alignment, can adsorb automatically fixedly, and side cut device 3 can begin the work of cutting edge, and is fixed for other anchor clamps, and this kind of fixed mode efficiency is higher.
