An automatic stretching mechanism comprises a bottom plate 1, a vertical plate 2 is fixedly connected to the top of the bottom plate 1, and a support block 3 is fixedly connected to the top of the vertical plate 2;

[0024] In the specific implementation process, Figure 1 , Figure 2 and Figure 3 As shown, the stretching component 4 is arranged on the top of the base plate 1, and the stretching component 4 includes a positioning block 41, a threaded rod 42, a pulling rod 43, a clamping plate 44 and a clamping block 45.

[0025] One end of the threaded rod 42 is fixedly connected to the first connecting rod 6 , and one end of the first connecting rod 6 is fixedly connected to the motor 7 .

[0026] A support frame 8 is fixedly connected to the top of the bottom plate 1 , a stabilizing frame 9 is fixedly connected to the top of the bottom plate 1 , a connecting block 10 is fixedly connected to one side of the stabilizing frame 9 , and the inner side of the stabilizing frame 9 is slidably connected to the pulling rod 43 .

[0027] The top of the clamping block 45 is fixedly connected with a threaded block 11 , both sides of the threaded block 11 are fixedly connected with fixed blocks 12 , and the inner side of the threaded block 11 is threadedly connected with the outer side of the threaded rod 42 .

[0028] A control frame 13 is disposed on the outer side of the pulling rod 43 , the inner side of the control frame 13 is rotatably connected to the connecting block 10 , and the inner side of the control frame 13 is slidably connected to the outer side of the fixing block 12 .

[0029] It should be noted that: the two pulling rods 43 are supported by the vertical plate 2, the support block 3, the support frame 8 and the two stabilizing frames 9 respectively, and the threaded rod 42 has threaded layers in opposite directions. Driven by the motor 7, the first connecting rod 6 drives the threaded rod 42 to rotate under the support of the positioning block 41, and then drives the two threaded blocks 11 to move respectively, so that the threaded block 11 drives the clamping block 45 to slide under the limit of the clamping plate 44, and then under the connection of the two fixed blocks 12, the two control frames 13 are respectively rotated under the support of the two connecting blocks 10, and then the two pulling rods 43 are pulled to move under the support of the support block 3, the support frame 8 and the stabilizing frame 9, so as to promote the realization of the stretching operation.

[0032] A cylinder 14 is disposed inside the fixing frame 51 . A piston rod of the cylinder 14 is fixedly connected to a second connecting rod 15 . One end of the second connecting rod 15 is fixedly connected to a positioning frame 16 .

[0034] It should be noted that: anti-skid pads 19 are installed on the top of the first clamping block 52 and the bottom of the second clamping block 18, which is beneficial to increase friction and avoid detachment during clamping, while reducing clamping and compression damage to the copper alloy plate. Driven by the cylinder 14, the second connecting rod 15 drives the positioning frame 16 to move, so that the positioning frame 16 pushes the connecting frame 55 to rotate under the limit of the fixed plate 53 and the fixed rod 54, and then drives the second clamping block 18 to move downward through the two positioning plates 17. With the cooperation of the first clamping block 52 and the anti-skid pad 19, the copper alloy plate is clamped and fixed.

[0035] The working principle of an automatic stretching mechanism provided by the utility model is as follows:

Under the drive of the cylinder 14, the second connecting rod 15 drives the positioning frame 16 to move. The positioning frame 16 pushes the connecting frame 55 to rotate under the limit of the fixing plate 53 and the fixing rod 54, and then drives the second clamping block 18 to move downward through the two positioning plates 17, so that the anti-skid pad 19 at the bottom of the second clamping block 18 contacts the top of the copper alloy plate. The copper alloy plate is clamped and fixed with the cooperation of the first clamping block 52. After both ends of the copper alloy plate are fixed, the first connecting rod 15 is driven by the motor 7. The connecting rod 6 drives the threaded rod 42 to rotate under the support of the positioning block 41, and then drives the two threaded blocks 11 to move respectively, so that the threaded block 11 drives the clamping block 45 to slide under the limit of the clamping plate 44, and then under the connection of the two fixed blocks 12, the two control frames 13 are respectively rotated under the support of the two connecting blocks 10, and then the two pulling rods 43 are pulled to move under the support of the support block 3, the support frame 8 and the stabilizing frame 9, so that the two pulling rods 43 are connected with the fixed frame 51, and the two ends of the copper alloy plate are synchronously pulled to move evenly, and the determined stretching trajectory makes it difficult for the copper alloy plate to deviate, thereby ensuring the straightness of the stretching effect.
