[0014] A non-cutting processing clamping device based on hollow metal tube processing and a method of use, comprising the following steps: S1: The second motor rotates, driving the first threaded rod to rotate, and the third movable block moves to the back side, thereby driving the fixed frame to move along the third drive box, thereby driving the fifth gear, the second rubber wheel and the sixth gear to move. At this time, the third gear is meshed with the sixth gear, and then the operator puts the blank between the two clamping assemblies, and then the operator starts the first motor to rotate to drive the third gear to rotate, thereby driving the sixth gear to rotate, thereby driving the second rubber wheel to rotate, thereby driving the first rubber wheel to rotate, thereby driving the second bevel gear to rotate, thereby driving the first bevel gear to rotate, thereby driving the rotating shaft to rotate, thereby driving the fourth gear to rotate, thereby driving the second gear to rotate, thereby driving the positive and negative threaded rods to rotate, thereby driving the two second movable blocks to approach each other, thereby driving the two clamping assemblies to approach each other, thereby clamping the blank. After the blank is clamped, the second gear cannot rotate at this time, thereby making the fourth gear, the rotating shaft and the first bevel gear unable to rotate, thereby making the second bevel gear and the first rubber wheel unable to rotate, but the first rubber wheel and the second rubber wheel can slip, thereby avoiding damage to the first motor due to the clamping of the third gear.

[0015] S2: Then the operator starts the second motor to rotate in the opposite direction, thereby driving the first threaded rod to rotate in the opposite direction, thereby driving the third movable block and the fixed frame to move in the opposite direction along the third drive box, thereby driving the fifth gear, the sixth gear and the second rubber wheel to move toward the front. At this time, the fifth gear is meshed with the third gear, and the third gear is separated from the sixth gear. At this time, the fifth gear is also meshed with the first gear. The rotation of the first motor drives the third gear to rotate, thereby driving the fifth gear to rotate, thereby driving the first gear to rotate, thereby driving the reciprocating screw to rotate, thereby driving the first movable block and the second drive box to move to the right, thereby driving the second movable block, the clamping assembly, the blank, the second gear and the ratchet to move to the right. When the blank is about to move to the right side of the first drive box, the ratchet engages with the rack. At this time, the rotation of the ratchet drives the positive and negative threaded rods to rotate, thereby driving the two second movable blocks to rotate mutually. When the two second movable blocks move away from each other, the two clamping assemblies are further away from each other, and a compression spring is arranged in the clamping assembly, so that the blank will not lose the clamping force instantly and fall off. As the two second movable blocks move away from each other, the elastic force of the compression spring decreases, so that the clamping force of the clamping block on the blank is reduced. When the ratchet moves to the extreme position, the distance between the two second movable blocks is the largest. At this time, the clamping assembly no longer clamps the blank, and the blank falls to complete the unloading. Then the reciprocating screw drives the first movable block to move in the opposite direction along the first drive box, and then drives the second drive box, the forward and reverse threaded rod and the ratchet to move synchronously. At this time, the ratchet is engaged with the rack, so that the ratchet rotates in the opposite direction, but the ratchet cannot drive the forward and reverse threaded rod to rotate. At this time, the distance between the two clamping assemblies is the largest. When the second drive box moves to the extreme position, the distance between the two clamping assemblies is the largest, which is convenient for the operator to feed the blank again, and the cycle is repeated.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention adopts an operator to adjust the rotation of the second motor through a controller, thereby driving the rotation of the first threaded rod, thereby driving the third movable block to move to the back side and adjusting it to the first working gear. Then the operator starts the first motor to rotate to drive the two clamping assemblies to approach each other, thereby clamping the blank. Then the operator starts the second motor to rotate in the opposite direction and adjusts it to the second working gear. Then the first motor is started to rotate to drive the clamping assembly, the blank, the second gear and the ratchet to move to the right side. Through the setting of the ratchet and the rack, automatic unloading is realized. The device has the advantage of being easy to use.

[0017] 2. The present invention arranges the clamping assembly so that when the two second movable blocks approach each other, the two fixed plates are driven to approach each other, and the two clamping blocks are driven to approach each other. When the clamping blocks clamp the blank, the compression springs are gradually compressed, and the blank is clamped by the elastic force of the compression springs themselves.

[0034] refer to Figure 1 A method for using a non-cutting processing clamping device based on hollow metal tube processing comprises the following steps: S1: The operator adjusts the second motor 20 to rotate through the controller 34, thereby driving the first threaded rod to rotate, thereby driving the third movable block 19 to move, thereby driving the fixed frame 21 to move, thereby driving the fifth gear 22, the second rubber wheel 23 and the sixth gear 24 to move. At this time, the third gear 11 is meshed with the sixth gear 24, and then the operator puts the blank between the two clamping assemblies 8, and then the operator starts the first motor 10 to rotate to drive the third gear 11 to rotate, thereby driving the sixth gear 24 to rotate, thereby driving the second rubber wheel 23 to rotate, thereby driving the first rubber wheel 17 to rotate, thereby driving the second bevel gear 16 to rotate, thereby driving the first bevel gear 15 rotates, thereby driving the rotating shaft 13 to rotate, thereby driving the fourth gear 14 to rotate, thereby driving the second gear 9 to rotate, thereby driving the positive and negative threaded rod 6 to rotate, thereby driving the two second movable blocks 7 to approach each other, thereby driving the two clamping assemblies 8 to approach each other, thereby clamping the blank. After the blank is clamped, the second gear 9 cannot rotate at this time, thereby making the fourth gear 14, the rotating shaft 13 and the first bevel gear 15 unable to rotate, thereby making the second bevel gear 16 and the first rubber wheel 17 unable to rotate, but the first rubber wheel 17 can slip with the second rubber wheel 23, thereby avoiding damage to the first motor 10 due to the clamping of the third gear 11.

[0035] S2: Then the operator starts the second motor 20 to rotate in the opposite direction, thereby driving the first threaded rod to rotate in the opposite direction, thereby driving the third movable block 19 and the fixed frame 21 to move in the opposite direction, thereby driving the fifth gear 22, the sixth gear 24 and the second rubber wheel 23 to move in the opposite direction. At this time, the fifth gear 22 is engaged with the third gear 11, and the third gear 11 is separated from the sixth gear 24. At this time, the fifth gear 22 is also engaged with the first gear 4. The first motor 10 rotates to drive the third gear 11 to rotate, thereby driving the fifth gear 22 to rotate, thereby driving the first gear 4 to rotate, thereby driving the reciprocating screw to rotate, thereby driving the first movable block 3 and the second drive box 5 to move to the right side, thereby driving the second movable block 7, the clamping assembly 8, the blank, the second gear 9 and the ratchet 30 to move to the right side. When the blank is about to move to the right side of the first drive box 2, the ratchet 30 is engaged with the rack 32. At this time, the rotation of the ratchet 30 drives the positive and negative threaded rod 6 to rotate, thereby driving the two second movable blocks 7 to move away from each other, and then When the second drive box 5 moves to the far left, the distance between the two clamping assemblies 8 is the largest, which is convenient for the operator to feed the blank again, and the cycle continues.

[0036] The working principle and use process of the present invention are as follows: when in use, the operator adjusts the second motor 20 to rotate through the controller 34, thereby driving the first threaded rod to rotate, thereby driving the third movable block 19 to move toward the back side, thereby driving the fixing frame 21 to move toward the back side, thereby driving the fifth gear 22, the second rubber wheel 23 and the sixth gear 24 to move toward the back side. At this time, the third gear 11 is meshed with the sixth gear 24, and then the operator places the blank between the two clamping assemblies 8. Then the operator starts the first motor 10 to rotate to drive the third gear 11 to rotate, thereby driving the sixth gear 24 to rotate, thereby driving the second rubber wheel 23 to rotate, thereby driving the first rubber wheel 17 to rotate, thereby driving the second bevel gear 16 to rotate, thereby driving the first bevel gear 15 to rotate. Then the rotating shaft 13 is driven to rotate, and then the fourth gear 14 is driven to rotate, and then the second gear 9 is driven to rotate, and then the positive and negative threaded rod 6 is driven to rotate, and then the two second movable blocks 7 are driven to approach each other, and then the two clamping assemblies 8 are driven to approach each other, and then the blank is clamped. After the blank is clamped, the second gear 9 cannot rotate at this time, and then the fourth gear 14, the rotating shaft 13 and the first bevel gear 15 cannot rotate, and then the second bevel gear 16 and the first rubber wheel 17 cannot rotate, but the first rubber wheel 17 can slip with the second rubber wheel 23, so as to avoid the first motor 10 being damaged due to the clamping of the third gear 11. Then the operator starts the second motor 20 to rotate in the opposite direction, and then drives the first threaded rod to rotate in the opposite direction, and then drives The third movable block 19 and the fixed frame 21 are driven to move, thereby driving the fifth gear 22, the sixth gear 24 and the second rubber wheel 23 to move toward the front. At this time, the fifth gear 22 is meshed with the third gear 11, and the third gear 11 is separated from the sixth gear 24. At this time, the fifth gear 22 is also meshed with the first gear 4. The first motor 10 rotates to drive the third gear 11 to rotate, thereby driving the fifth gear 22 to rotate, thereby driving the first gear 4 to rotate, thereby driving the reciprocating screw to rotate, thereby driving the first movable block 3 and the second drive box 5 to move to the right, thereby driving the second movable block 7, the clamping assembly 8, the blank, the second gear 9 and the ratchet 30 to move to the right. When the blank is about to move to the extreme position of the first drive box 2, the ratchet 30 is meshed with the rack 32 At this time, the rotation of the ratchet 30 drives the positive and negative threaded rod 6 to rotate, thereby driving the two second movable blocks 7 to move away from each other, and then driving the two clamping assemblies 8 to move away from each other. A compression spring 28 is arranged in the clamping assembly 8, so that the blank will not lose the clamping force instantly and fall off. As the two second movable blocks 7 move away from each other, the elastic force of the compression spring 28 decreases, so that the clamping force of the clamping block 27 on the blank is reduced. When the ratchet 30 moves to the far right, the distance between the two second movable blocks 7 is the largest. At this time, the clamping assembly 8 no longer clamps the blank, and the blank falls to the surface of the unloading plate 33, and then slides to the right side of the first driving box 2. Then the reciprocating screw drives the first movable block 3 to move to the left, thereby driving the second driving box 5, the positive and negative threaded rod 6 and the ratchet 30 to move to the left.At this time, the ratchet 30 is meshed with the rack 32, so that the ratchet 30 rotates in the opposite direction, but the ratchet 30 cannot drive the forward and reverse threaded rod 6 to rotate. At this time, the distance between the two clamping assemblies 8 is the largest. When the second drive box 5 moves to the far left, the distance between the two clamping assemblies 8 is the largest, which is convenient for the operator to feed the blank again, and the cycle is repeated.

10. A method for using a non-cutting processing clamping device based on hollow metal tube processing, characterized in that: A non-cutting processing device based on hollow metal tube processing comprising any one of claims 1 to 9: S1: The second motor (20) rotates, driving the first threaded rod to rotate, the third movable block (19) moves to the back, and then drives the fixed frame (21) to move along the third drive box (18), and then drives the fifth gear (22), the second rubber wheel (23) and the sixth gear (24) to move. At this time, the third gear (11) is meshed with the sixth gear (24), and then the operator puts the blank between the two clamping assemblies (8). Then the operator starts the first motor (10) to rotate and drive the third gear (11) to rotate, and then drive the sixth gear (24) to rotate, and then drive the second rubber wheel (23) to rotate, and then drive the first rubber wheel (17) to rotate, and then drive the second bevel gear (16) to rotate, and then drive the first bevel gear (15) The first gear (16) and the second gear (17) rotate, thereby driving the rotating shaft (13) to rotate, thereby driving the fourth gear (14) to rotate, thereby driving the second gear (9) to rotate, thereby driving the positive and negative threaded rod (6) to rotate, thereby driving the two second movable blocks (7) to approach each other, thereby driving the two clamping assemblies (8) to approach each other, thereby clamping the blank. After the blank is clamped, the second gear (9) cannot rotate, thereby making the fourth gear (14), the rotating shaft (13) and the first bevel gear (15) unable to rotate, thereby making the second bevel gear (16) and the first rubber wheel (17) unable to rotate, but the first rubber wheel (17) and the second rubber wheel (23) can slip, thereby avoiding damage to the first motor (10) caused by the clamping of the third gear (11); S2: The operator then starts the second motor (20) to rotate in the opposite direction, thereby driving the first threaded rod to rotate in the opposite direction, thereby driving the third movable block (19) and the fixing frame (21) to move in the opposite direction along the third driving box (18), thereby driving the fifth gear (22), the sixth gear (24) and the second rubber wheel (23) to move forward. At this time, the fifth gear (22) is meshed with the third gear (11), and the third gear (11) is separated from the sixth gear (24). At this time, the fifth gear (22) is also meshed with the first gear (4), and the first motor (10 ) rotates to drive the third gear (11) to rotate, thereby driving the fifth gear (22) to rotate, thereby driving the first gear (4) to rotate, thereby driving the reciprocating screw to rotate, thereby driving the first movable block (3) and the second drive box (5) to move to the right, thereby driving the second movable block (7), the clamping assembly (8), the blank, the second gear (9) and the ratchet (30) to move to the right. When the blank is about to move to the right side of the first drive box (2), the ratchet (30) meshes with the rack (32). At this time, the rotation of the ratchet (30) drives the positive and negative threaded rod (6) to rotate. , thereby driving the two second movable blocks (7) to move away from each other, thereby driving the two clamping assemblies (8) to move away from each other, a compression spring (28) is arranged in the clamping assembly (8), so that the blank will not lose the clamping force instantly and fall off, as the two second movable blocks (7) move away from each other, the elastic force of the compression spring (28) decreases, so that the clamping force of the clamping block (27) on the blank is reduced, when the ratchet (30) moves to the limit position, the distance between the two second movable blocks (7) is the maximum, at this time the clamping assembly (8) no longer clamps the blank, the blank falls off to complete the unloading, and then the reciprocating wire The rod drives the first movable block (3) to move in the opposite direction along the first drive box (2), thereby driving the second drive box (5), the positive and negative threaded rod (6) and the ratchet (30) to move synchronously. At this time, the ratchet (30) is meshed with the rack (32), so that the ratchet (30) rotates in the opposite direction, but the ratchet (30) cannot drive the positive and negative threaded rod (6) to rotate. At this time, the distance between the two clamping assemblies (8) is the largest. When the second drive box (5) moves to the extreme position, the distance between the two clamping assemblies (8) is the largest, which is convenient for the operator to feed the blank again, and the cycle is repeated.
