Description

Technical Field

[0001] The present invention relates to the technical field of cable cutting, in particular to a device for batch cutting cables to a fixed length. Background Art

[0002] In the production and manufacturing of automotive cables, in order to better utilize space for layout and avoid space waste and wiring difficulties caused by inconsistent cable lengths, the wire part of the cable needs to be cut to equal lengths.

[0003] The Chinese invention patent with publication number CN117884548A provides a conveniently transported cutting device for automotive wiring harness processing. Before the wiring harness is cut, the patent can drive the wiring harness to move equidistantly through the cooperation between the traction mechanism and the clamping mechanism, thereby cooperating with the cutting mechanism to cut the wiring harness equidistantly to obtain wiring harnesses of the same length, saving the process of manual measurement or calibration and improving the efficiency of wiring harness cutting. Before the wiring harness is cut, one end of the wiring harness is clamped and fixed, and then the wiring harness is automatically flattened through the cooperation between the various components of the correction mechanism, effectively preventing the wiring harness from bending, thereby avoiding the problem of the wiring harness bending affecting the cutting accuracy.

[0004] However, the above patent does not limit and align the end of the automotive cable, so that the position of the cable end fixed on the clamping mechanism is uncertain, which leads to errors in the method of determining the length of the cable by the movement of its clamping mechanism, and thus the accuracy of the fixed-length cutting of the cable is not high. In addition, the above patent adopts the method of pressing the cable and pulling the cable to straighten it. Since the protective cover on the outside of the cable is generally made of elastic rubber material, when the cable is pulled, it is easy for the rubber jacket and the internal wire to slide relative to each other, thereby affecting the quality of the cable.

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention adopts an electric slider to drive the alignment square cylinder to move toward the end of the cable, so that the alignment square cylinder moves to the outside of the cover arranged at the end of the cable. When the end of the cable moves to the fixed position inside the alignment square cylinder, the cable and the alignment square cylinder can be fixedly connected together through the wire clamping assembly. Then, the electric slider drives the end of the cable to move to the fixed position on the fixed plate through the alignment square cylinder, so that the starting point of the end of each section of cable to be cut is consistent, and then the movement of the electric slider can pull the cable end to move synchronously, thereby determining the cutting length of the cable, and finally the cable is cut to equal length by the cutting knife, thereby improving the accuracy of the fixed-length cutting of the cable.

[0019] 2. The present invention adopts an electric slider to drive the end of the cable to move from bottom to top through the positioning square cylinder, so that the cable can maintain a certain vertical state under the action of its own gravity. At the same time, the straightening component can push the cable in sections, so that the cable always maintains a vertical state during the movement, and there is no need to pull the cable to straighten it. Therefore, while ensuring the accuracy of the fixed-length cutting of the cable, the quality of the cable can also be guaranteed. The straightening component can straighten the cable during the movement of the cable, so there is no need to wait for the cable to be moved before straightening it, which saves the cable adjustment time and increases the cable cutting efficiency.

[0020] 3. The present invention adopts a wire clamping assembly which can not only fix the cable and the positioning square tube together, but also squeeze the four sides of the cable while clamping, so that the part of the cable inside the positioning square tube is in a vertical state, thereby further ensuring the verticality of the cable and further increasing the accuracy of the fixed-length cutting of the cable.

[0021] Fourth, the present invention uses a pusher assembly in conjunction with a cutting knife to cut the cables on the vertical rack in batches, so that the present invention can cut the cables to a fixed length in batches, thereby further increasing the cable cutting efficiency.

DETAILED DESCRIPTION

[0033] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0034] See Figure 1 and Figure 2 A device for batch cutting cables to fixed lengths comprises a vertical frame 1, a shaft 2 is rotatably provided at the center position of the vertical frame 1, fixed plates 5 are fixedly installed at equal intervals along the circumference of the shaft 2 on the outside of the vertical frame 1, a pulling mechanism 3 for pulling the cables to equal lengths is provided on the fixed plate 5, and a discharge mechanism 4 for cutting and unloading the cables is provided on both the vertical frame 1 and the fixed plate 5.

[0035] When the cable needs to be cut to equal lengths, the end of the cable is first pulled to the side of the lower part of the fixing plate 5 away from the shaft 2, and then the end of the cable is fixed by the discharge mechanism 4. Subsequently, the end of the cable is clamped and driven to the initial position by the pulling mechanism 3, and then the end of the cable is pulled to equal lengths by the pulling mechanism 3. While pulling the cable, the pulling mechanism 3 can also push and straighten the cable in real time. When the end of the cable is pulled to the desired position, the cable is cut and unloaded by the discharge mechanism 4.

[0036] See Figure 1 、 Figure 3 and Figure 4 The discharge mechanism 4 includes a wire fixing assembly 44 arranged at the lower part of the side of the fixed plate 5 away from the shaft rod 2. The wire fixing assembly 44 includes a rectangular frame 441 fixedly installed at the lower part of the side of the fixed plate 5 away from the shaft rod 2. A clamping plate 442 is symmetrically slidingly arranged inside the rectangular frame 441. A synchronous plate 443 is rotatably arranged in the middle of one side of the rectangular frame 441. The two ends of the synchronous plate 443 are respectively hinged to the two clamping plates 442 through hinge plates 444. A hydraulic push rod 445 is fixedly installed on the side of the two clamping plates 442 away from the synchronous plate 443. A rectangular hole running through the middle of the rectangular frame 441 is opened.

[0037] When the cable needs to be cut to equal length, the operator holds the end of the cable and passes it from bottom to top through the rectangular hole of the rectangular frame 441. Then the operator pulls the end of the cable upward so that the end of the cable is a certain distance away from the upper end surface of the rectangular frame 441. At this time, the cable is positioned between the two clamps 442. Then the telescopic section of the hydraulic push rod 445 is retracted so that the hydraulic push rod 445 drives the two clamps 442 to approach each other. When one side of the clamp 442 moves, the corresponding hinged plate 444 is used to push the synchronous plate 443 to rotate. The synchronous plate 443 pulls the corresponding clamp 442 to move synchronously through the other hinged plate 444, so that the two clamps 442 move synchronously in opposite directions, so that the clamp 442 clamps the cable and fixes it in the middle position of the rectangular hole.

[0038] See Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 The wire pulling mechanism 3 includes an electric slider 31 which is slidably arranged in the vertical direction on the side of the fixed plate 5 away from the shaft rod 2. A positioning square cylinder 32 is fixedly installed on the side of the electric slider 31 away from the shaft rod 2. A wire clamping assembly 33 for clamping the cable is provided inside the positioning square cylinder 32. The wire clamping assembly 33 includes a trigger plate 331 which is arranged on the upper side of the positioning square cylinder 32 by sliding up and down through a guide column. A push spring is provided between the trigger plate 331 and the positioning square cylinder 32. Four wire clamping plates 332 are provided at equal intervals on the lower inner part of the positioning square cylinder 32 along the circumference of the guide column. The wire clamping plates 332 are slidably connected to the frame of the corresponding position of the positioning square cylinder 32 along the length direction. The wire clamping plates 332 are provided with clearance grooves at equal intervals along the length direction thereof, and the two wire clamping plates 332 which are perpendicular to each other are interlaced and arranged.

[0039] In the initial state, the clamping plates 332 are all located away from the center of the alignment square cylinder 32. After the cable is fixed on the rectangular frame 441, the electric slider 31 is started to drive the alignment square cylinder 32 to move downward, so that the alignment square cylinder 32 drives the lower side of the trigger plate 331 to rest against the upper end surface of the cable. At this time, the alignment square cylinder 32 is covered on the outside of the upper end of the cable, and the cable is located between the four clamping plates 332 inside the alignment square cylinder 32. Then, the alignment square cylinder 32 continues to move downward, and the reaction force of the cable end on the trigger plate 331 pushes the trigger plate 331 to move upward relative to the alignment square cylinder 32.

[0040] See Figure 1 、 Figure 3 、 Figure 5 and Figure 6When the locking plate 331 is unlocked, the locking plate 332 is unlocked and the locking plate 333 is unlocked, so that the master lock 3333 can be unlocked.

[0041] When the trigger plate 331 moves upward relative to the positioning square tube 32 until it contacts the inclined surface of the limit plate 3341, the trigger plate 331 pushes the limit plate 3341 in the direction away from the shaft 2. When the trigger plate 331 passes over the limit plate 3341 and moves to rest against the blocking block 3342, the limit plate 3341 returns to its initial position under the pull of the tension spring, so that the limit plate 3341 and the blocking block 3342 cooperate to limit the position of the trigger plate 331 in the vertical direction. At this time, the trigger plate 331 drives the push spring to be in a compressed state, so that the upper end of the cable is close to the lower side surface of the trigger plate 331, thereby uniformly limiting the position of the end of the cable inside the positioning square tube 32.

[0042] See Figure 3 、 Figure 5 and Figure 6 The wire clamping assembly 33 also includes a driving part 333 arranged on the positioning square cylinder 32, and the driving part 333 includes an executive motor 3331 fixedly mounted on one side of the positioning square cylinder 32. The side of the positioning square cylinder 32 away from the shaft rod 2 and the side connected to the executive motor 3331 are both rotatably provided with a bidirectional screw 3332. The side of the wire clamping plate 332 away from the center of the positioning square cylinder 32 is threadedly connected to the bidirectional screw 3332 through an ear plate. The ends of the two bidirectional screws 3332 close to each other are fixedly mounted with bevel gears 3333, and the two bevel gears 3333 are meshed with each other. The output shaft of the executive motor 3331 is connected to the bidirectional screw 3332 at the corresponding position through a belt.

[0043] When the limit plate 3341 returns to its initial position, the electric slider 31 stops moving downward and starts the execution motor 3331 to drive the bidirectional screw 3332 connected to it to rotate. The two bidirectional screws 3332 rotate synchronously through the bevel gear 3333. Then the bidirectional screw 3332 drives the two clamping plates 332 on it to approach each other, so that the four clamping plates 332 inside the alignment square cylinder 32 move synchronously toward the center position of the alignment square cylinder 32, and then the clamping plates 332 clamp the cable in the center position of the alignment square cylinder 32, and the clamping plates 332 push the cable around, so that the part of the cable inside the alignment square cylinder 32 can be in a vertical state.

[0044] See Figure 1 、 Figure 3 、 Figure 5 and Figure 6 The wire pulling mechanism 3 also includes a convex plate 35 fixedly installed on the lower part of the fixing plate 5 away from the shaft rod 2, a pneumatic push rod 321 is fixedly installed on the lower part of the positioning square tube 32 away from the shaft rod 2, and a positioning plate 322 is fixedly installed on the upper part of the convex plate 35 away from the shaft rod 2.

[0045] When the wire clamping plate 332 is clamped on the outside of the cable, the telescopic section of the pneumatic push rod 321 is fully extended, and then the telescopic section of the hydraulic push rod 445 is retracted, so that the clamping plate 442 no longer clamps the cable, and then the electric slider 31 drives the end of the cable to move upward through the positioning square cylinder 32, so that the positioning square cylinder 32 synchronously drives the pneumatic push rod 321 to move upward, and when the telescopic section of the pneumatic push rod 321 moves to abut against the lower side of the positioning plate 322, the electric slider 31 stops moving, so that the positioning square cylinder 32 drives the end of the cable to the initial position at this time, and then the telescopic section of the pneumatic push rod 321 is retracted, and then the electric slider 31 starts to drive the cable to move upward, and the length of the cable is measured by the distance moved by the electric slider 31.

[0046] See Figure 1 、 Figure 3 and Figure 8The wire pulling mechanism 3 also includes a straightening clamping assembly 34 arranged on the side of the fixed plate 5 away from the shaft rod 2. The straightening clamping assembly 34 includes several groups of pushing cover frames 341 arranged at equal intervals in the vertical direction on the side of the fixed plate 5 away from the shaft rod 2. Each group of pushing cover frames 341 is composed of a pushing cover frame 341 symmetrically arranged on the fixed plate 5. The side of the pushing cover frame 341 away from the shaft rod 2 is a V-shaped structure, and the side of the pushing cover frame 341 close to the shaft rod 2 is a plate-shaped structure. The plate-shaped structure of the pushing cover frame 341 close to the shaft rod 2 is slidably connected to the fixed plate 5 along the width direction of the fixed plate 5 through a supporting square rod. A support plate 342 is symmetrically fixedly installed on the side of the fixed plate 5 away from the shaft rod 2, and a coil spring is provided between the support plate 342 and the pushing cover frame 341. A pushing frame plate 343 is symmetrically slidably provided on the V-shaped structure of the pushing cover frame 341, and an active spring is provided between the pushing frame plate 343 and the pushing cover frame 341.

[0047] See Figure 1 、 Figure 3 、 Figure 5 and Figure 8 The upper and lower sides of the plate-shaped structure of the pushing cover frame 341 are provided with inclined surfaces near the middle of the fixed plate 5, and the inclined surfaces of the plate-shaped structure of the pushing cover frame 341 are provided with sliding grooves. An active push plate 344 is fixedly installed on the outer side of the electric slider 31 away from the shaft rod 2. The upper and lower sides of the active push plate 344 are pointed structures, and sliding protrusions 345 for inserting into the sliding grooves are fixedly installed on the inclined surfaces of the pointed structures of the active push plate 344. An electric push rod 346 is fixedly installed symmetrically on the upper and lower sides of the active push plate 344 close to the shaft rod 2. A locking portion 347 is commonly provided on the plate-shaped structure of the same group of pushing cover frames 341.

[0048] See Figure 5 、 Figure 8 and Figure 9 When the cam 347 is in the unlock state, the latch 347 is locked and the latch 347 is in the unlock state, and the latch 347 is in the unlock state, so that the cam 347 is locked and the latch 347 is in the unlock state.

[0049] In the initial state, a group of push cover frames 341 located on the upper part of the opposing square tube 32 are in a state of being close to each other and combined together, so that the same group of push cover frames 341 drives the isosceles trapezoidal structure of the fastener 3472 thereon to be inserted between the two L-shaped locking members 3471 at the corresponding positions, so that the L-shaped locking member 3471 limits the fastener 3472 to prevent the fastener 3472 from moving in the direction away from the L-shaped locking member 3471, thereby making the two push cover frames 341 in the same group close together.

[0050] When the locking plate 347 is unlocked, the locking plate 347 is unlocked and the locking plate 348 is unlocked, so that the locking plate 348 is unlocked and the locking plate 348 is unlocked.

[0051] When the two pushing cover frames 341 in the same group move away from each other, the pushing cover frames 341 drive the latch 3472 and the L-shaped locking member 3471 to move away from each other, and at the same time make the unlocking plate 3473 move away from the electric push rod 346. Then, the No. 3 spring drives the unlocking plate 3473 to return to the initial position through its own elastic force, and the No. 2 spring drives the latch 3472 to return to the initial position synchronously through its own elastic force. The two pushing cover frames 341 in the same group move away from each other while compressing the coil springs in the corresponding positions.

[0052] When the active push plate 344 moves upward to the position where the pointed end on its lower side corresponds to the inclined surface on the upper side of the plate structure of the push cover frame 341, the coil spring pushes the push cover frame 341 toward the middle of the fixed plate 5 through its own elastic force, so that the upper inclined surface of the plate structure of the push cover frame 341 slides against the pointed end surface on the lower side of the active push plate 344, thereby causing the sliding groove on the inclined surface on the upper side of the plate structure of the push cover frame 341 to slide to connect with the sliding protrusion 345 on the pointed end on the lower side of the active push plate 344, and then the active push plate 344 drives the two push cover frames 341 in the same group at the lower part to move and combine together.

[0053] When the push cover frames 341 are combined together, the push cover frames 341 drive the internal push frame plate 343 to press against the four sides of the cable, so that the active spring drives the push frame plate 343 to push and straighten the cable through its own elastic force. Since the active spring elastic force pushes the push cover frames 341, the push cover frames 341 have a force to move in the direction away from the cable, so that the two push cover frames 341 in the same group may not be able to be completely combined together due to the elastic force of the coil spring, and thus the push frame plate 343 cannot effectively push and straighten the cable. The active push plate 344 is connected to the sliding groove on the push cover frame 341 through the sliding protrusion 345, which can force the two push cover frames 341 in the same group to move and combine together, thereby ensuring the effect of the push frame plate 343 on pushing and straightening the cable.

[0054] It should be noted that the cross-sections of the sliding protrusion 345 and the sliding groove on the pushing cover frame 341 are both isosceles trapezoidal structures, so that after the sliding protrusion 345 is inserted into the sliding groove on the pushing cover frame 341, the sliding protrusion 345 and the pushing cover frame 341 are slidably connected together.

[0055] When the two push cover frames 341 in the same group at the lower part of the active push plate 344 are completely moved and combined together, the sliding protrusion 345 is completely moved to the outside of the sliding groove on the push cover frame 341, so that the sliding protrusion 345 is disconnected from the push cover frame 341. At the same time, the same group of push cover frames 341 drives the isosceles trapezoidal structure of the fastener 3472 thereon to be inserted between the two L-shaped locking members 3471 at the corresponding positions again, thereby making the two push cover frames 341 in the same group at the lower part of the active push plate 344 stably fixed and combined together.

[0056] See Figure 1 、 Figure 2 and Figure 3 The discharge mechanism 4 also includes a mounting support plate 41 that is symmetrically fixed between the upper and lower sides of the inner side of the fixed plate 5. A cutting knife 42 is arranged at equal intervals on the lower side of the lower mounting support plate 41 along the circumference of the shaft 2. The cutting knife 42 is slidably connected to the lower mounting support plate 41 along the radial direction of the shaft 2. The cutting knife 42 and the shaped plate 35 are located in the same horizontal plane. A rectangular groove corresponding to the cutting knife 42 is provided on the fixed plate 5. A pushing component 43 for unloading the cut cable is commonly provided on the upper mounting support plate 41 and the vertical frame 1.

[0057] Continue reading Figure 1 、 Figure 2 and Figure 3The pushing assembly 43 includes a pushing plate 431 symmetrically fixedly mounted on the shaft 2 in the upper and lower directions. The pushing plate 431 is located between the two mounting support plates 41. A roller frame 432 is provided on the upper side of the upper mounting support plate 41 at equal intervals along the circumference of the shaft 2. The roller frame 432 is slidably connected to the upper mounting support plate 41 along the radial direction of the shaft 2. A roller 433 is provided for rotating the roller frame 432 away from the end of the shaft 2. A driving motor 434 is fixedly mounted on the roller frame 432. The output shaft of the driving motor 434 The No. 1 roller 433 is connected to the corresponding position through a belt, and the No. 2 roller frame 435 corresponding to the No. 1 roller frame 432 is fixedly installed on the side of the fixed plate 5 away from the shaft 2. The No. 2 roller 436 is rotatably provided on the side of the No. 2 roller frame 435 away from the shaft 2. The pushing plate 431 is provided with pushing oblique grooves at equal intervals along its circumference. The No. 1 roller frame 432 and the cutting knife 42 slide in the pushing oblique grooves at the corresponding positions through the raised columns thereon, and a rotating motor 437 connected to the shaft 2 is fixedly installed on the upper side of the vertical frame 1.

[0058] When the electric slider 31 drives the end of the cable to move to the specified position, the telescopic section of the hydraulic push rod 445 is extended to drive the clamping plate 442 to clamp the cable, and then the rotating motor 437 is started to drive the shaft 2 to rotate, and the shaft 2 drives the two pushing discs 431 to rotate synchronously. The pushing disc 431 drives the No. 1 roller frame 432 and the cutting knife 42 to move away from the shaft 2 through the pushing oblique groove thereon, so that the cutting knife 42 passes through the fixed plate 5 to cut the cable. While the cable is cut, the No. 1 roller frame 432 drives the No. 1 rotating roller 433 to move against the cable, and then continues to rotate the shaft 2, so that the No. 1 rotating roller 433 pushes the cable against the No. 2 roller frame 435.

[0059] Then the motor 3331 is reversed so that the wire clamping plate 332 no longer clamps the cable, and then the drive motor 434 is started to drive the No. 1 roller 433 to rotate, so that the No. 1 roller 433 pushes the cable to the outside of the vertical frame 1, thereby completing the fixed-length cutting of the cable, and then the electric slider 31 drives the limiting plate 3341 to move upward until it contacts the inclined surface of the lifting plate 3343, so that the lifting plate 3343 moves the limiting plate 3341 away from the shaft 2, and then the pushing spring pushes the trigger plate 331 downward to reset through its own elastic force, and then the electric slider 31 drives the positioning square cylinder 32 to move downward until it covers the end of the cable again, thereby automatically cutting the cable to equal length.

[0060] It should be noted that when the electric slider 31 drives the active push plate 344 to move downward, the telescopic section of the lower electric push rod 346 is extended and the telescopic section of the upper electric push rod 346 is retracted to prevent the push cover frame 341 from obstructing the downward movement of the electric slider 31.

[0061] When cutting the cable to a fixed length, the present invention further includes the following steps:

[0062] In the first step, the cable is passed through the rectangular hole of the rectangular frame 441 , and then the telescopic section of the hydraulic push rod 445 is retracted so that the clamping plate 442 clamps and fixes the cable in the middle position of the rectangular hole of the rectangular frame 441 .

[0063] The second step is to start the electric slider 31 to drive the alignment square cylinder 32 to move downward, so that the cable end pushes the trigger plate 331 to move upward relative to the alignment square cylinder 32 to between the blocking block 3342 and the limit plate 3341, stop the electric slider 31 and start the execution motor 3331, so that the clamping plate 332 clamps the cable at the center position of the alignment square cylinder 32.

[0064] The third step is to extend the telescopic section of the pneumatic push rod 321 and retract the telescopic section of the hydraulic push rod 445, and drive the pneumatic push rod 321 to move upward through the electric slider 31 until it rests on the lower side of the positioning plate 322, so that the positioning square tube 32 drives the end of the cable to the initial position. Then, the telescopic section of the pneumatic push rod 321 is retracted, and then the electric slider 31 starts to drive the cable to move upward, and the length of the cable is measured by the distance the electric slider 31 moves.

[0065] In the fourth step, the electric slider 31 drives the active push plate 344 to push the two push cover frames 341 in the same group away from each other, and then the active push plate 344 drives the two push cover frames 341 in the same group below it to move and combine together, so that the push cover frame 341 drives the internal push frame plate 343 to press against the four sides of the cable, so that the active spring drives the push frame plate 343 to push and straighten the cable through its own elastic force.

[0066] In the fifth step, the electric slider 31 drives the end of the cable to move to the specified position, extends the telescopic section of the hydraulic push rod 445 to drive the clamping plate 442 to clamp the cable, and then starts the rotating motor 437, so that the cutting knife 42 passes through the fixed plate 5 to cut the cable, and then the No. 1 roller frame 432 drives the No. 1 rotating roller 433 to push the cable against the No. 2 roller frame 435.

[0067] In the sixth step, the motor 3331 is reversed so that the wire clamping plate 332 no longer clamps the cable, and then the drive motor 434 is started to push the cable to the outside of the vertical frame 1 through the No. 1 roller 433, thereby completing the fixed-length cutting of the cable. After that, the electric slider 31 drives the limiting plate 3341 to move upward until it contacts the inclined surface of the lifting plate 3343, so that the trigger plate 331 moves downward and resets. After that, the electric slider 31 drives the positioning square cylinder 32 to move downward until it covers the end of the cable again, thereby automatically cutting the cable to equal lengths.

[0068] Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention, and these changes shall still be within the scope of protection of the present invention.
