s2, when the shaft part only leaves the outer wall clamped by the first clamping plate 9 and the end part is not machined, the two overturning motors 4 rotate ninety degrees in the direction of the moving motor 7, and the moving motor 7 rotates to enable the main gear 1 to drive the displacement rack 6 to be close to the first mounting seat 8, so that a clamping and exchanging process is carried out;
S3, when the end of the shaft part is level with the end of the follower column 28, the moving motor 7 stops rotating, the clamping motor II 33 rotates to drive the transmission gear I30 and the transmission gear column 32 to rotate, so that the transmission gear ring 31 and the limiting slide rail I291 are driven to rotate, and the mounting rod 23 slides along the limiting slide rail I291 to enable the clamping rubber 38 to clamp the outer wall of the shaft part;
S4, the mobile motor 7 continues to rotate to drive the second mounting seat 3 to be close to the first mounting seat 8, and twenty-five follow-up columns 28 are clung to the end parts of the special-shaped shaft parts when the follow-up columns 28 are clung to the end parts of the special-shaped shaft parts;
s5, when any follower column 28 is retracted into the second limiting slide rail 29 to the maximum extent, the triangular block 52 can abut against the trigger frame body 44, so that the trigger frame body 44 moves for one section, the intermittent rack frame 42 drives the locking gear 43 to rotate ninety degrees, the locking cam 53 rotates to push the mounting plate 45 to the follower column 28, the locking plate 47 clamps the outer wall of the follower column 28, the position of each follower column 28 at the moment is locked, and the elastic force of the fourth reset spring 49 is prevented from acting on shaft parts;
s6, the second sliding rod 35 moves downwards along with the shape-following column 28, and the trigger frame body 44 is just clamped in the clamping block rod 41 when moving, so that the position of the second sliding rod 35 is locked;
S7, when the second sliding rod 35 drives the fixed frame 25 to move to the maximum extent, the third gear 40 is meshed with the second rack 27, the third gear 40 drives the rotating cylinder 26 to rotate, so that the rotating cylinder 26 winds the traction rope 34, the traction rope 34 pulls the clamping rubber 38 downwards and inwards, the clamping of the clamping rubber 38 on the outer wall of the special-shaped shaft part is further enhanced, and the force to the second mounting seat 3 is given to the clamping rubber 38;
s8, the first clamping motor 13 reversely contacts with the clamping of the first clamping plate 9, the end part and the outer wall of the shaft part can be comprehensively machined, and the second clamping motor 33 reversely rotates after machining is finished and can be reset.
The specific working principle and the use method of the invention are explained in detail below, as shown in fig. 1-4, firstly, the end part of the shaft part is placed on the first mounting seat 8, then the first clamping motor 13 rotates to drive the clamping gear 14 to rotate, the clamping gear 14 drives the three racks 11 to be close to each other, when the first clamping plate 9 contacts with the outer wall of the shaft part, the clamping side plate 15 also contacts with the outer wall of the shaft part, so that the shaft part can be better clamped, and meanwhile, the first gear 19 rotates in an engaged manner along the first rack 18, so that the rubber ring 21 always rotates, and when the rubber ring 21 contacts with the outer wall of the shaft part, the force of the rubber ring facing the first mounting seat 8 can be given to the shaft part, so that the rubber ring 21 always clings to the shaft part, and the accuracy of the center line of the shaft part is ensured.
As shown in fig. 1, when the outer wall and the end part of the shaft part clamped by the first clamping plate 9 are not machined, the two overturning motors 4 rotate ninety degrees in the direction of the moving motor 7, and the moving motor 7 rotates to enable the main gear 1 to drive the displacement rack 6 to be close to the first mounting seat 8, so that the clamping and exchanging process is performed.
