All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] For example, see Figure 1 - Fig.10 The present invention provides a technical solution for the tool holder structure of a wire cutting machine for wire harness processing: the wire cutting machine for wire harness processing comprises: a wire cutting machine body 1 and a tool holder frame 2, the outer wall of the front side of the wire cutting machine body 1 is fixedly connected to the inner part of the back side of the tool holder frame 2, the outer wall of the top of the tool holder frame 2 is fixedly connected to a cylinder 21, the output end of the cylinder 21 is fixedly connected to a push rod 22, the outer wall of the bottom of the push rod 22 is fixedly connected to a mounting plate 23, the outer wall of the bottom of the mounting plate 23 is fixedly connected to a cutting knife 24, the outer wall of the push rod 22 is slidably connected to a connecting plate 32, and both ends of the bottom of the connecting plate 32 are fixedly connected to an upper pressing plate 3.

[0018] The cutting knife 24 is continuously pushed downward by the mounting plate 1 23 to enter the interior of the limiting shell 4 to cut the wire harness. After the cutting knife 24 has finished cutting the wire harness, the outer wall of the cutting knife 24 can be cleaned by the cleaning plate 41 arranged on the limiting shell 4 when the cutting knife 24 is moved out from the interior of the limiting shell 4, thereby avoiding the cutting knife 24 from being adhered to debris and affecting the sharpness of the cutting knife 24 through the accumulation of debris, thereby ensuring that the cutting knife 24 always maintains its original sharpness. Maintaining the sharpness of the cutting knife 24 not only improves the work efficiency, but also ensures the stability of the work quality. At the same time, the sharp cutting knife 24 is less likely to break or fail accidentally during operation, thereby improving the safety of the workplace.

[0019] Embodiment 2. On the basis of embodiment 1, a second slide groove 61 is provided on one side opposite to the two upper pressure plates 3, and a cavity is provided on the outer wall of one side of the second slide groove 61, and a reset spring 63 is fixedly connected inside the cavity, and the outer wall of one end of the reset spring 63 is fixedly connected to the limit rod 62, and the outer walls on both sides of the mounting plate 1 23 are fixedly connected to the driving rod 6, and the outer wall of the driving rod 6 is slidably connected to the inside of the second slide groove 61, and the outer wall of the driving rod 6 is in movably contact with the outer wall of the limit rod 62, and the outer wall of the bottom of the upper pressure plate 3 is fixedly connected to the plug block 31, and the outer wall of the bottom of the plug block 31 is fixedly connected to the magnetic plate 33, and the lower part of the tool holder frame 2 is fixedly connected to the lower solid shell 34, and the two lower solid shells 34 are slidably connected to the mounting plate 2 36, and the outer wall of the top of the mounting plate 36 is fixedly connected to the iron plate 35, and the outer wall of the top of the iron plate 35 is magnetically connected to the outer wall of the bottom of the mounting plate 2 36, and the outer wall of the plug block 31 is movably plugged into the inside of the lower solid shell 34.

[0020] When the upper pressing plate 3 drives the insert block 31 to be inserted into the lower solid shell 34, the insert block 31 can push the mounting plate 2 36 inside the lower solid shell 34 downward. When the bottom of the upper pressing plate 3 contacts the top of the lower solid shell 34, the insert block 31 can completely enter the lower solid shell 34, thereby completing the fixation of the wire harness by the upper pressing plate 3 and the lower solid shell 34, avoiding the rolling of the wire harness during cutting, and correspondingly increasing the neatness and precision of the cutting edge of the wire harness, reducing the number of cutting failures or repeated cutting caused by the rolling of the wire harness, thereby improving the cutting efficiency and reducing the production cost.

[0021] Embodiment 3, on the basis of embodiment 2, the lower solid shell 34 is internally rotatably connected with a threaded rod 5, a worm 52 is fixedly connected below the outer wall of the threaded rod 5, the outer wall of the threaded rod 5 is threadedly connected to the inner wall of the second mounting plate 36, a threaded hole is provided in the middle of the outer wall of the second mounting plate 36, the outer wall of the threaded rod 5 is threadedly connected to the inner wall of the threaded hole, a circular hole is provided on the outer wall of the bottom of the plug block 31 at the position of the threaded rod 5, the outer wall of the threaded rod 5 is slidably connected to the inner wall of the circular hole, a U-shaped fixing groove 53 is fixedly connected to one side of the threaded rod 5 at the lower part of the interior of the lower solid shell 34, a support rod is fixedly connected to the inside of the U-shaped fixing groove 53, and the support rod The outer wall of the worm wheel 54 is rotatably connected to the outer wall of the worm wheel 54, and the outer wall of the worm wheel 54 is meshed with the outer wall of the worm 52. The outer wall of one side of the worm wheel 54 is fixedly connected to a transmission wheel 1 57, and the outer wall of the transmission wheel 1 57 is rotatably connected to a conveyor belt 55. A slide groove 1 51 is provided on the opposite side of the two lower solid shells 34, and the inner wall of the slide groove 1 51 is rotatably connected to the outer wall of the conveyor belt 55. The inside of the conveyor belt 55 is rotatably connected to a transmission wheel 2 59, and the outer wall of one side of the transmission wheel 2 59 is fixedly connected to a gear 58, and the outer wall of the gear 58 is fixedly connected to a tooth seat 56. The axis of the gear 58 passes through a support rod for rotation connection, and the outer walls at both ends of the support rod are fixedly connected to a fixed shell.

[0022] The fixed connection between the worm gear 54 and the transmission wheel 1 57 ensures their synchronous rotation, and the transmission belt 55 transmits the movement to the transmission wheel 2 59 through friction. The synchronous and coordinated movement mode ensures the stability and reliability of the transmission system, thereby ensuring that the limit shell 4 can move upward smoothly. This series of power transmission and conversion ensures the effective use of energy and the accuracy of transmission. The entire transmission process is automatically controlled and can be completed without human intervention.

[0023] Embodiment 4, on the basis of embodiment 3, one side of the tooth seat 56 is fixedly connected to the limiting shell 4, the interior of the limiting shell 4 is hollow, and cleaning plates 41 are fixedly connected to both sides of the interior of the limiting shell 4, the interior of the limiting shell 4 is movably plugged into the outer wall of the cutting knife 24, and the outer walls on both sides of the limiting shell 4 are provided with U-shaped grooves.

[0024] The wire harness enters the U-shaped groove on the limiting shell 4, which guides the path of the cutting knife 24 when it moves downward, avoiding the cutting knife 24 from deviating during the downward movement, which causes a large error in the length of the wire harness cut. Accordingly, when the path of the cutting knife 24 is limited, the error in cutting the wire harness can be reduced, and the cutting knife 24 can cut the wire harness vertically, further increasing the flatness and beauty of the cutting area of ​​the wire harness.

[0025] In actual use, when cutting the wire harness, first, start the cylinder 21 on the tool holder frame 2, and then through the operation of the cylinder 21, the push rod 22 can drive the mounting plate 23 to move downward, and then use the movement of the mounting plate 23 to drive the cutting knife 24 and the driving rod 6 to move downward at the same time, and then through the movement of the driving rod 6 in the second slide groove 61, the driving rod 6 generates a thrust to the limit rod 62 to move downward, and at this time, the movement of the limit rod 62 can drive the upper pressing plate 3 to move downward, and the upper pressing plate 3 drives the plug 31 to be inserted into When the upper pressing plate 3 and the lower solid shell 34 are in contact with each other, the plug block 31 can completely enter the lower solid shell 34, thereby completing the fixation of the wire harness by the upper pressing plate 3 and the lower solid shell 34, avoiding the rolling of the wire harness during cutting, and correspondingly increasing the neatness and precision of the cutting edge of the wire harness, reducing the number of cutting failures or repeated cutting caused by the rolling of the wire harness, thereby improving the cutting efficiency and reducing the production cost.

[0026] By providing the anti-skid pads on the upper pressing plate 3 and the lower solid shell 34 , when the upper pressing plate 3 and the lower solid shell 34 fix the wire harness, the upper pressing plate 3 and the lower solid shell 34 can further fix the wire harness.

[0027] By setting the magnetic plate 33 and the iron plate 35, when the magnetic plate 33 and the iron plate 35 are magnetically connected, the plug block 31 can be further fixed inside the lower solid shell 34, thereby increasing the close contact between the plug block 31 and the mounting plate 2 36, avoiding the plug block 31 from being separated from the inside of the lower solid shell 34 when the tool holder frame 2 is subjected to external force, and correspondingly increasing the fixation of the upper pressure plate 3 and the lower solid shell 34 to the wire harness, further improving the stability of the wire harness during the cutting process.

[0028] When the second mounting plate 36 moves downward inside the lower solid shell 34, the threaded rod 5 can be driven to rotate accordingly. Then, the threaded rod 5 rotates, so that the worm 52 drives the worm wheel 54 to rotate. Then, through the fixed connection between the worm wheel 54 and the transmission wheel 1 57, the transmission wheel 1 57 can be driven to rotate when the worm wheel 54 rotates. Then, through the movement of the transmission wheel 1 57, the conveyor belt 55 drives the transmission wheel 2 59 to rotate accordingly. At this time, the gear 58 moves accordingly, and then the gear 58 is used to rotate. Movement can make the tooth seat 56 drive the limiting shell 4 to move upward, so that the wire harness enters the U-shaped groove on the limiting shell 4, and guides the path of the cutting knife 24 when it moves downward to cut the wire harness, avoiding the cutting knife 24 from deviating during the downward movement, causing a large error in the length of the wire harness cut. Accordingly, when the path of the cutting knife 24 is limited, the error of the wire harness during cutting can be reduced, and the cutting knife 24 can cut the wire harness vertically, further increasing the flatness and beauty of the cutting part of the wire harness.

[0029] When the bottom of the upper pressing plate 3 contacts the top of the lower solid shell 34, the upper pressing plate 3 can no longer move downward. At this time, when the push rod 22 continues to push the mounting plate 1 23 downward, the mounting plate 1 23 can drive the driving rod 6 to further squeeze the limiting rod 62. At this time, the limiting rod 62 is subjected to the squeezing force, which will push the return spring 63 to cause the return spring 63 to be deformed and shortened. At this time, the limiting rod 62 will enter the interior of the cavity, so that the mounting plate 1 23 can continue to push the cutting knife 24 downward to enter the interior of the limiting shell 4 to cut the wire harness. After the cutting of the wire harness is completed, the outer wall of the cutting knife 24 can be cleaned by the cleaning plate 41 provided on the limiting shell 4 when the cutting knife 24 is moved out from the inside of the limiting shell 4, thereby avoiding the cutting knife 24 from being adhered to debris and affecting the sharpness of the cutting knife 24 through the accumulation of debris, thereby ensuring that the cutting knife 24 always maintains its original sharpness. Maintaining the sharpness of the cutting knife 24 not only improves work efficiency, but also ensures the stability of work quality. At the same time, the sharp cutting knife 24 is less likely to break or fail accidentally during operation, thereby improving the safety of the workplace.

[0030] When the first mounting plate 23 drives the driving rod 6 and the cutting knife 24 to move upward, the driving rod 6 pushes the bottom of the limiting rod 62 to move upward. At this time, the movement of the limiting rod 62 can make the magnetic plate 33 pull the iron plate 35 and the second mounting plate 36 to move upward inside the lower solid shell 34. When the iron plate 35 is transported to the upper part of the lower solid shell 34, it can pass through the opening above the lower solid shell 34 that is smaller than the length of the iron plate 35, so that the iron plate 35 can no longer move upward. At this time, when the driving rod 6 continues to push the limiting rod 62 to move upward, it will squeeze the limiting rod 62, so that the limiting rod 62 enters the interior of the cavity, so that the driving rod 6 moves to the uppermost part of the second slide groove 61, and then through the setting of the return spring 63, the limiting rod 62 can be fixed under the driving rod 6, thereby completing the resetting of the driving rod 6, which is helpful for the driving rod 6 to be used again, and the driving rod 6 can continue to push the limiting rod 62 to move downward.

[0031] When the driving rod 6 enters the second slide groove 61 and the mounting plate 1 23 continues to drive the driving rod 6 to move upward, the upper pressure plate 3 can drive the magnetic plate 33 to separate from the iron plate 35, so that the iron plate 35 can move freely without being attracted by the magnetic force, thereby returning the iron plate 35 to its original position. When the iron plate 35 drives the mounting plate 2 36 to move upward inside the lower solid shell 34, the mounting plate 2 36 can drive the threaded rod 5 to rotate in the opposite direction, and then the threaded rod 5 is rotated in the forward direction, so that the gear 58 can drive the tooth seat 56 to move downward, so that the tooth seat 56 drives the limiting shell 4 to return to its original position. The movement of the mounting plate 2 36 can drive the threaded rod 5 to move, thereby reducing the need for manual intervention and correspondingly improving the efficiency of restoring each component to its original position.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
