Description

A tool switching mechanism for a wire and cable stripping machine Technical Field

[0001] This utility model relates to the field of tool switching technology, and more specifically, to a tool switching mechanism for a wire and cable stripping machine. Background Technology

[0002] A cable stripper is a specialized piece of equipment used to remove the outer sheath of a cable to expose the internal conductors. It is widely used in electrical installation, electronics manufacturing, and communications engineering. Its core function is to efficiently and precisely strip the cable insulation layer using mechanical or automated methods.

[0003] In existing cable stripping machines, when dealing with cables that do not meet the required stripping speed, it is necessary to change the blades to different lengths. Generally, when changing the blades, the handle is rotated, which drives the threaded rod to rotate. Through the threaded connection between the threaded rod and the top frame, both the threaded rod and the handle move backward. When the handle and the threaded rod move backward, the pressing block that contacts the side of the blade moves backward, causing the pressing block to gradually move away from the blade surface. However, since this device mainly fixes the blade through the friction between the pressing block and the blade, when switching is needed, the pressing block can be removed to replace the blade. However, during use, the cable exerts an upward force on the blade, which leads to increased wear at the contact point between the pressing block and the blade after prolonged use. As the pressing block is used for a long time, the friction between the pressing block and the blade surface decreases. Therefore, it is necessary to modify and optimize the device. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a tool switching mechanism for a wire and cable stripping machine, which solves the technical problems of stable fixation and easy installation in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tool switching mechanism for a wire and cable stripping machine, comprising a top frame and a fixed cylinder, wherein the fixed cylinder is movably disposed above the top frame, and the bottom of the fixed cylinder extends into the interior of the top frame and is movably connected to the top frame;

[0006] A cutter is movably mounted on the top of the fixed cylinder. The bottom of the cutter penetrates the upper and lower sides of the fixed cylinder. A rotating rod is rotatably mounted on the side of the fixed cylinder. One end of the rotating rod extends into the interior of the fixed cylinder and is fixedly mounted with a threaded rod II. Threaded block I and threaded block II are threadedly sleeved on the outer surface of threaded rod II. Threaded block II is located on one side of threaded block I. A handle II is fixedly mounted on one end of the rotating rod. A limit rod is fixedly mounted between the inner sides of the fixed cylinder. There are two threaded blocks I and two threaded blocks II. Another threaded block I and threaded block II are located on the outer surface of the limit rod and are movably sleeved with the limit rod. An arc-shaped plate is fixedly mounted between the two threaded blocks I and the two threaded blocks II. The arc-shaped plate is movably connected to the cutter. Two retaining rings are fixedly sleeved on the outer surface of threaded rod II. The two retaining rings are located on the sides of threaded blocks I and threaded blocks II, respectively.

[0007] As a preferred embodiment of this utility model, the top frame has a groove 1 inside, a spring is fixedly installed on one side of the groove 1, a push plate is fixedly installed on one end of the spring, a baffle is rotatably installed on one side of the push plate, a fixed plate is movably installed on the top of the top frame, the bottom of the fixed plate extends into the interior of the top frame, a push rod is movably installed on one side of the top frame, one end of the push rod passes through the left and right sides of the fixed plate and extends into the interior of the groove 1 to movably connect with the baffle, and the top frame has a second groove and a third groove inside.

[0008] In a preferred embodiment of this utility model, the fixing plate is located on the side of the fixing cylinder, and one side of the fixing plate is fixedly connected to the fixing cylinder.

[0009] As a preferred embodiment of this utility model, an arc-shaped baffle is fixedly installed on the side of the arc-shaped plate, and the side of the arc-shaped baffle is movably connected to the cutting tool.

[0010] As a preferred embodiment of this utility model, the bottom of the cutter extends through the upper and lower sides of the top frame and is movably connected to the top frame.

[0011] As a preferred embodiment of this utility model, vertical plates are fixedly installed on both the left and right sides of the top frame, and a base frame is fixedly installed at the bottom of the vertical plates.

[0012] As a preferred embodiment of this utility model, a rotating shaft is rotatably installed between the two vertical plates, and a roller is movably sleeved on the outer surface of the rotating shaft.

[0013] As a preferred embodiment of this utility model, a threaded rod is rotatably mounted on the side of the roller, and one end of the threaded rod extends into the interior of the roller and is movably connected to the rotating shaft.

[0014] As a preferred embodiment of this utility model, the threaded rod is threadedly connected to the roller, and a handle is fixedly installed at one end of the threaded rod.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] 1. In this disclosure, rotating the handle two drives the rotating rod to rotate, which in turn drives the threaded rod two to rotate. When the threaded rod two rotates, it drives the threaded block one and the threaded block two to move, thereby driving the arc plate and the arc baffle to move and fix the position of the tool. Compared with the traditional device, which fixes the tool by friction between the extrusion block and the tool, when the extrusion block and the tool wear more, the friction between the tool and the extrusion block will decrease, resulting in insufficient fixing force. This device fixes the tool from above, which improves the stability of fixing the tool and thus improves the working efficiency of the device.

[0018] 2. In this disclosure, by moving the push rod into the interior of the groove, and then rotating the push rod 90 degrees, the push rod can be moved backward when it is rotated 90 degrees, so that the push rod moves out of the interior of the fixed plate, thereby moving the fixed cylinder upward. Compared with the traditional device, this device allows the fixed cylinder to be disassembled by disassembling the fixed plate, which facilitates the installation of the tool. At the same time, the tool can be replaced more quickly by using multiple spare fixed cylinders. Attached Figure Description

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] As shown in Figures 1 to 9, this utility model provides a tool switching mechanism for a wire and cable stripping machine, including a top frame 1 and a fixed cylinder 8. The fixed cylinder 8 is movably disposed above the top frame 1, and the bottom of the fixed cylinder 8 extends into the interior of the top frame 1 and is movably connected to the top frame 1.

[0037] A cutter 17 is movably mounted on the top of the fixed cylinder 8. The bottom of the cutter 17 penetrates the upper and lower sides of the fixed cylinder 8. A rotating rod 18 is rotatably mounted on the side of the fixed cylinder 8. One end of the rotating rod 18 extends into the interior of the fixed cylinder 8 and is fixedly mounted with a threaded rod 19. Threaded blocks 20 and 21 are threadedly fitted onto the outer surface of the threaded rod 19. Threaded block 21 is located on one side of threaded block 20. A handle 24 is fixedly mounted on one end of the rotating rod 18. A limit rod 25 is fixedly mounted between the sides inside the fixed cylinder 8. Threaded blocks 20 and 21... There are two of each type of 21. The other threaded block 1 20 and threaded block 21 are located on the outer surface of the limiting rod 25. The other threaded block 1 20 and threaded block 21 are movably sleeved with the limiting rod 25. An arc plate 22 is fixedly installed between the two threaded blocks 1 20 and between the two threaded blocks 21. The arc plate 22 is movably connected to the cutter 17. Two retaining rings 26 are fixedly sleeved on the outer surface of the threaded rod 29. The two retaining rings 26 are located on the sides of the threaded blocks 1 20 and the threaded blocks 21, respectively. The threaded rod 29 is composed of two threaded rods with opposite threads.

[0038] When the operator uses the device, they first rotate handle 24. Rotating handle 24 causes rotating rod 18 to rotate, which in turn causes threaded rod 19 to rotate. As threaded rod 19 rotates, the threads 20 and 21, connected to threaded block 21, are threaded. This rotation causes threaded blocks 20 and 21 to move, which in turn moves arc plate 22. This movement of arc plate 22 then moves arc baffle 23. When the inner side of arc baffle 23 contacts the tool 17, or when arc baffle 23 moves above the tool 17, rotating handle 24 can be stopped. Two retaining rings 26 limit the movement distance of threaded blocks 20 and 21.

[0039] By rotating handle 24, the rotating rod 18 is driven to rotate. As the rotating rod 18 rotates, the threaded rod 19 rotates. When the threaded rod 19 rotates, it drives the threaded block 20 and the threaded block 21 to move, thereby driving the arc plate 22 and the arc baffle 23 to move and fix the position of the cutter 17. Compared with the traditional device, which fixes the cutter 17 by friction between the extrusion block and the cutter 17, when the extrusion block and the cutter 17 wear more, the friction between the cutter 17 and the extrusion block will decrease, resulting in insufficient fixing force. This device fixes the cutter 17 from above, which improves the stability of fixing the cutter 17 and thus improves the working efficiency of the device.

[0040] The top frame 1 has a groove 9 inside, a spring 10 is fixedly installed on one side inside the groove 9, a push plate 11 is fixedly installed on one end of the spring 10, a baffle 12 is rotatably installed on one side of the push plate 11, a fixed plate 16 is movably installed on the top of the top frame 1, the bottom of the fixed plate 16 extends into the interior of the top frame 1, a push rod 15 is movably installed on one side of the top frame 1, one end of the push rod 15 passes through the left and right sides of the fixed plate 16 and extends into the interior of the groove 9 to movably connect with the baffle 12, and the top frame 1 has a second groove 13 and a third groove 14 inside.

[0041] When the operator uses the device, they first move the push rod 15 into the groove 9. When the push rod 15 moves into the groove 9, the baffle 12 moves into the groove 9. When the baffle 12 moves, it drives the push plate 11 to move, which compresses the spring 10. Then, by rotating the push rod 15 90 degrees, the push rod 15 can be moved backward. The push rod 15 will enter the groove 14. As the push rod 15 moves backward, it will move out of the fixed plate 16. After the push rod 15 moves out of the fixed plate 16, the fixed cylinder 8 can be lifted upward.

[0042] By moving the push rod 15 into the groove 9 and then rotating the push rod 15 90 degrees, the push rod 15 can be moved backward, causing it to move out of the fixed plate 16. This allows the fixed cylinder 8 to be moved upward. Compared with the conventional device, this device allows the fixed cylinder 8 to be disassembled by removing the fixed plate 16, which facilitates the installation of the tool 17. At the same time, the tool 17 can be replaced more quickly by using multiple spare fixed cylinders 8.

[0043] The fixing plate 16 is located on the side of the fixing cylinder 8, and one side of the fixing plate 16 is fixedly connected to the fixing cylinder 8.

[0044] The connection between the fixing plate 16 and the fixing cylinder 8 allows the fixing cylinder 8 to be fixed after the fixing plate 16 is fixed.

[0045] Among them, an arc-shaped baffle 23 is fixedly installed on the side of the arc-shaped plate 22, and the side of the arc-shaped baffle 23 is movably connected to the cutter 17.

[0046] The arc-shaped baffle 23 can block the upward movement of the tool 17 and increase the friction between the tool 17 and the baffle.

[0047] The bottom of the cutter 17 extends through the upper and lower sides of the top frame 1 and is movably connected to the top frame 1.

[0048] The design of the blade 17 improves the efficiency of stripping wires and cables.

[0049] The top frame 1 has vertical plates 2 fixedly installed on both the left and right sides, and the bottom frame 3 is fixedly installed on the bottom of the vertical plates 2.

[0050] The design of the vertical plate 2 and the base frame 3 supports the position of the top frame 1, improving the stability of the top frame 1 itself.

[0051] Among them, a rotating shaft 4 is rotatably installed between the two vertical plates 2, and a roller 5 is movably sleeved on the outer surface of the rotating shaft 4.

[0052] The design of roller 5 allows for the restriction of the position of wires and cables.

[0053] Among them, a threaded rod 6 is rotatably mounted on the side of the roller 5, and one end of the threaded rod 6 extends into the interior of the roller 5 and is movably connected to the rotating shaft 4.

[0054] The rotation of the threaded rod 6 allows one end of the threaded rod 6 to come into contact with the rotating shaft 4, thereby fixing the roller 5.

[0055] Among them, threaded rod 6 is threadedly connected to roller 5, and handle 7 is fixedly installed at one end of threaded rod 6.

[0056] Rotating handle 7 can drive the threaded rod 6 to rotate, thus facilitating the rotation of the threaded rod 6.

[0057] Among them, groove 2 13 and groove 3 14 are movably connected to push rod 15, and the interior of groove 2 13 and the interior of groove 3 14 are interconnected with the interior of groove 1 9.

[0058] The design of groove 2 13 and groove 3 14 facilitates the movement of push rod 15, while also facilitating its fixation.

[0059] Working principle and usage process of this utility model:

[0060] When the operator uses the device, they first rotate handle 24. Rotating handle 24 causes rotating rod 18 to rotate, which in turn causes threaded rod 19 to rotate. As threaded rod 19 rotates, the threads 20 and 21, connected to threaded block 21, are threaded. This rotation causes threaded blocks 20 and 21 to move, which in turn moves arc plate 22. This movement of arc plate 22 then moves arc baffle 23. When the inner side of arc baffle 23 contacts the tool 17, or when arc baffle 23 moves above the tool 17, rotating handle 24 can be stopped. Two retaining rings 26 limit the movement distance of threaded blocks 20 and 21.

[0061] When the operator uses the device, they first move the push rod 15 into the groove 9. When the push rod 15 moves into the groove 9, the baffle 12 moves into the groove 9. When the baffle 12 moves, it drives the push plate 11 to move, which compresses the spring 10. Then, by rotating the push rod 15 90 degrees, the push rod 15 can be moved backward. The push rod 15 will enter the groove 14. As the push rod 15 moves backward, it will move out of the fixed plate 16. After the push rod 15 moves out of the fixed plate 16, the fixed cylinder 8 can be lifted upward.
