Detailed Implementation

[0018] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0019] like Figure 1-4 As shown, a cable sheath installation fixture mainly consists of a support frame 1, a worktable 2, a sheath support assembly, an end support assembly, a left-right moving assembly, and a sheath expansion assembly. The worktable is mounted on the support frame. The sheath expansion assembly, sheath support assembly, and end support assembly are arranged on the worktable from left to right, and a left-right moving assembly is provided between the end support assembly and the worktable. The sheath support assembly is used to hold the sheath 3. The left-right moving assembly can drive the end support assembly to move, allowing the cable 4 to pass through the sheath 3. The end support assembly is used to hold the end of the cable 4, and the sheath expansion assembly is used to expand the sheath 3.

[0020] During operation, the cable is initially inserted into the sheath, and then the cable with the sheath is placed accordingly. The cable is supported by the end support component, and the sheath is located inside the sheath support component. Then the sheath expansion component expands the sheath, and finally the left and right movement component operates to allow the cable to pass through the expanded sheath.

[0021] Specifically, the sheath support assembly includes a sheath support base 5 mounted on a worktable via front and rear support legs. At least two sheath placement slots for placing sheaths are spaced apart on the sheath support base 5. A sheath limiting block 6 is provided on the right side of the sheath support base 5. A second cable slot for inserting a cable is provided on the sheath limiting block 6 corresponding to each sheath placement slot. Right-side limiting is achieved by the difference in size between the second cable slot and the sheath placement slot.

[0022] The sheath expansion assembly includes a steel pipe 16 for blowing air into the sheath. An air blowing device is provided at the left end of the steel pipe 16, and a fixing ring 17 for supporting the steel pipe is provided near the left end of the steel pipe 16. The fixing ring 17 is provided on the output end of the steel pipe telescopic cylinder 18, so that the steel pipe can move left and right under the action of the steel pipe telescopic cylinder. The right end of the steel pipe 16 is slidably provided on the steel pipe through hole in the sheath clamping block 19. When the steel pipe telescopic cylinder works, it can drive the steel pipe through the sheath clamping block and extend into the sheath.

[0023] To achieve the left limit of the sheath, the sheath clamping block 19 is positioned at the output end of the sheath clamping cylinder 20, meaning the sheath clamping block is mounted on the moving block of the sheath clamping cylinder. This allows the sheath clamping cylinder to move the sheath clamping block left and right. During operation, the sheath clamping cylinder's operation causes the sheath clamping block to abut against the left side of the sheath support seat. Ideally, a guide rod structure is provided on the worktable to ensure the linear movement of the sheath clamping cylinder. Specifically, a guide rod support seat is provided on the worktable, with the left and right ends of the guide rod located between the sheath clamping cylinder and its moving block.

[0024] To prevent the sheath from detaching upwards from the sheath placement slot, a sheath limiting component is provided on the worktable 2 to prevent the sheath from leaving the sheath placement slot. The sheath limiting component includes a sheath limiting cylinder 7 mounted on the worktable 2, and a sheath pressing block 8 that can move back and forth is provided at the output end of the sheath limiting cylinder 7. That is, the sheath pressing block is mounted on the moving block of the sheath limiting cylinder. Under the action of the sheath limiting cylinder, the sheath pressing block can move above all the sheath placement slots to prevent the sheath from detaching from the sheath placement slot.

[0025] The end support assembly includes an end support block 9 and an end limiting block 10. The end support block 9 is provided with a first cable groove for placing the end of the cable, and the end limiting block 10 is located at the output end of the end clamping cylinder 11. The end clamping cylinder can move the end limiting block left and right, thereby pressing against the end of the cable, which facilitates the subsequent insertion of the cable into the sheath.

[0026] To achieve automatic material unloading, a material unloading assembly is provided on the worktable 2. The unloading assembly includes a material unloading frame 28 located at the rear of the worktable 2 and a material unloading motor 30. A material unloading shaft 31 extending laterally is provided at the output end of the material unloading motor 30, and the material unloading shaft 31 is mounted on the worktable 2 via two spaced-apart material unloading support seats 32. A plurality of material unloading components 33 for cable unloading are spaced apart on the material unloading shaft 31. In this embodiment, the material unloading motor is mounted on the material unloading support seats near it via a material unloading mounting base.

[0027] Specifically, the unloading component includes an unloading body sleeved on the unloading shaft, a cable lifting block for lifting the cable is provided on the unloading body, and when the unloading component is not working, the cable lifting block is located below the cable in the end support component. A guide block is also provided on the unloading body to ensure that the cable can fall smoothly into the unloading frame.

[0028] Ideally, a sheath placement frame 34 for placing sheaths and a cable placement frame 35 for placing cables are provided at intervals on the left and right sides of the front side of the workbench 2.

[0029] To accommodate cables of different lengths, the sheath expansion assembly is mounted on the worktable via the sheath adjustable assembly, and the end support assembly is mounted on the left and right moving assembly via the end adjustable assembly. The end adjustable assembly includes an end adjustment slider mounted on the moving block of the left and right moving assembly, with a sliding connection between the end adjustment slider and the moving block. An end clamping cylinder 11 is mounted on the end adjustment slider 12, and an end adjustment block 13 is mounted on the end adjustment slider 12 behind the end clamping cylinder. An end adjustment fixing block 14 is fixedly mounted behind the moving block of the left and right moving assembly, and an end adjustment rod 15 for adjusting the position of the end adjustment block is positioned between the end adjustment block 13 and the end adjustment fixing block 14.

[0030] The adjustable sheath assembly includes a sheath clamping adjustment block 21, which is slidably mounted on a guide rail fixed to the workbench 2. A sheath clamping cylinder 20 is mounted on the sheath clamping adjustment block 21. A sheath adjusting fixing block 22 is provided on the left side of the workbench 2. A sheath adjusting rod 23 for adjusting the position of the sheath clamping adjustment block 21 is provided between the sheath clamping adjustment block 21 and the sheath adjusting fixing block 22.

[0031] To facilitate the positioning of the sheath tightening adjustment block and the end adjustment block on the adjustment rod, two locking blocks are provided on both the end adjustment rod and the sheath adjustment rod. Each locking block includes two spaced-apart nuts with a connecting sleeve between them. The end adjustment block, end adjustment fixing block, sheath tightening block, and sheath adjustment fixing block all have notches for the connecting sleeve to engage from top to bottom. Adjustment is achieved simply by rotating the locking blocks on the sheath tightening adjustment block and the end adjustment block.

[0032] When the cable is long, an intermediate support assembly is also provided on the workbench 2 for convenient support. The intermediate support assembly includes a lifting cylinder 24, a lifting block 25 is provided at the output end of the lifting cylinder 24, a front-to-back moving cylinder 26 is provided on the lifting block 25, and an intermediate support block 27 is provided at the output end of the front-to-back moving cylinder 26. When the cable is long, the operation of the front-to-back moving cylinder causes the intermediate support block to move between the sheath support assembly and the end support assembly. During material unloading, the lifting cylinder works to assist in material unloading.

[0033] The left and right movement mechanism is an existing technology and can be implemented using a motor lead screw module.

[0034] When the cable is short, the working process is as follows: First, the cable is initially threaded into the sheath, then placed on the corresponding component, so that the cable is supported by the first cable groove and the second cable groove, and ensuring that the end of the sheath is between the end support block 9 and the end limiting block 10, and the sheath is located in the sheath placement groove. Then, the equipment is started, the sheath limiting cylinder works, so that the sheath pressing block presses against the top of the sheath, and then the sheath clamping cylinder works, so that the sheath clamping block abuts against the left side of the sheath support seat. When the steel pipe telescopic cylinder operates, the right end of the steel pipe extends into the sheath. Then, the end-clamping cylinder operates, causing the end-limiting block to press against the cable. Next, the left-right moving component operates, allowing the cable to pass through the sheath. Then, the end-clamping cylinder, steel pipe telescopic cylinder, and sheath clamping cylinder operate in opposite directions, causing the corresponding end-limiting block, steel pipe, and sheath clamping block to return to their original positions. The feeding motor operates, realizing feeding. Finally, the left-right moving component drives the end-support component to return to its original position, and the feeding motor also returns to its original position.

[0035] When the cable is long, the intermediate support block moves between the sheath support assembly and the end support assembly under the action of the front and rear moving cylinders. The working process is as follows:

[0036] First, thread the cable through the sheath, then place it on the corresponding component, ensuring the cable is supported by the first cable groove, the second cable groove, and the intermediate support block. Ensure the sheath end is positioned between the end support block 9 and the end limiting block 10, and the sheath is within the sheath placement groove. Then, start the equipment; the sheath limiting cylinder activates, pressing the sheath pressure block against the top of the sheath. Next, the sheath clamping cylinder activates, pressing the sheath clamping block against the left side of the sheath support seat. Finally, the steel pipe telescopic cylinder activates. The right end of the steel pipe is extended into the sheath, and then the end-clamping cylinder is activated, causing the end-limiting block to press against the cable. Then, the left-right moving component is activated, allowing the cable to pass through the sheath. The end-clamping cylinder, the steel pipe telescopic cylinder, and the sheath clamping cylinder then work in opposite directions, causing the corresponding end-limiting block, steel pipe, and sheath clamping block to return to their original positions. The feeding motor and lifting rod work simultaneously to feed the material. Finally, the left-right moving component drives the end-support component to return to its original position, and the feeding motor and lifting rod also return to their original positions.
