[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 , a multi-station circular tube clamping device, including a fixed seat 2, on which multiple groups of rib plates are fixedly arranged in parallel. At the same time, multiple groups of V-shaped grooves are opened on each group of rib plates. A group of circular tube workpieces 1 are placed in the V-shaped grooves distributed in the same column on the multiple groups of rib plates. The setting of multiple columns of V-shaped grooves enables the simultaneous clamping and placement of multiple groups of circular tube workpieces 1, and wear-resistant strips 3 are fixedly laid in the V-shaped grooves. The wear-resistant strips 3 are used to support the circular tube workpieces 1. The material of the wear-resistant strips 3 is selected from 45# steel or 40Gr, and surface wear-resistant treatment is performed to increase the service life;

[0021] Pressing plates 4 are arranged between the adjacent front and rear groups of rib plates and between the adjacent left and right groups of V-shaped grooves on the fixed seat 2. The two sides of the pressing plates 4 are respectively pressed on the adjacent two groups of circular tube workpieces 1. A locking screw 5 passes through the hole opened in the middle of the pressing plate 4. The bottom end of the locking screw 5 is screwed into the threaded hole opened on the fixed seat 2. By screwing the locking screw 5, the pressing plate 4 is controlled to press the circular tube workpiece 1 to fix the circular tube workpiece 1 and prevent the circular tube workpiece 1 from moving and rotating.

[0022] Please refer to Figure 1, a multi-station circular tube clamping device, one end of the fixed seat 2 is fixed with a reference plate 7, and one end face of the circular tube workpiece 1 abuts against the reference plate 7.

[0023] Please refer to Figure 1 , a multi-station circular tube clamping device, a ejector rod 6 is arranged below the circular tube workpiece 1 on the fixed seat 2. The ejector rod 6 is located between two adjacent sets of corrugated plates in the front and rear. The top end of the ejector rod 6 contacts the bottom of the circular tube workpiece 1 placed in the V-shaped groove. The ejector rod 6 is used to support the circular tube workpiece 1 to prevent the circular tube workpiece 1 from vibrating due to insufficient rigidity during processing. The bottom end of the ejector rod 6 is a threaded section that can be screwed into the threaded hole opened on the fixed seat 2 for adjusting the height of the ejector rod 6 extending out to match the circular tube workpiece 1.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
