Description

Technical Field

[0001] This utility model relates to the field of cable cutting technology, and in particular to a positioning mechanism for a wire cutting machine. Background Technology

[0002] When signals are transmitted through cables, they experience attenuation and distortion as the distance increases. In applications requiring extremely high signal quality, such as high-speed data transmission (e.g., high-speed buses within computers, high-speed interconnections between servers), high-definition video transmission (e.g., connections between professional film and television production equipment), and precision measuring instruments, using shorter cables can effectively reduce signal loss and interference during transmission, ensuring signal integrity and accuracy, and improving system performance and stability.

[0003] The applicant's research revealed that in existing cable cutting mechanisms, cables are generally in a coiled state before cutting. Existing equipment only clamps and fixes the cable during the cutting operation, which may cause bending during cutting, leading to errors and affecting cutting accuracy. Furthermore, the cable needs support plates during cutting, and after cutting, it must be manually removed, which is inconvenient and increases the workload of staff.

[0004] Therefore, the applicant proposes a positioning mechanism for a thread cutting machine to solve the problem. Utility Model Content

[0005] This utility model provides a positioning mechanism for a thread cutting machine, which solves the problems mentioned in the background.

[0006] To solve the above technical problems, this utility model provides a positioning mechanism for a wire cutting machine, including a base plate. A cutting component for cutting cables is installed on the upper surface of the base plate, and a feeding component for collecting the cut cables is installed below the cutting component. Two sets of support blocks are symmetrically fixedly connected to the upper surface of the base plate, and a straightening component is movably provided between one set of support blocks and a movable block.

[0007] A positioning plate for positioning the cable is fixedly connected to the upper surface of the base plate;

[0008] The straightening assembly includes a limiting block located above the second spring. Two sets of second piston cylinders are installed inside a set of support blocks. The inner walls of the two sets of second piston cylinders are movably fitted with second piston rods extending to the upper end of the support block. The upper surface of the base plate is symmetrically and fixedly connected with first piston cylinders. The inner walls of the first piston cylinders are movably fitted with first piston rods fixedly connected to both ends of the limiting block. A connecting pipe is fixedly connected between the second piston cylinder and the first piston cylinder.

[0009] Preferably, the cutting assembly includes three sets of cutters for cutting the cable. Two sets of connecting blocks are fixedly connected to both sides of one set of cutters. A pressure plate for squeezing and limiting the cable is provided below each of the two sets of connecting blocks. A plug rod that moves through the top of each of the two sets of pressure plates is fixedly connected to the top of the connecting blocks. A first spring that is fixedly connected to the pressure plate and the plug rod is sleeved on the outer wall of the plug rod.

[0010] Preferably, the feeding assembly includes a support plate located below the cutting assembly. The upper end of the support plate has three sets of through slots corresponding to the cutter. The upper end of the base plate is fixedly connected to two sets of fixing rods. The support plate is rotatably mounted on the side wall of the fixing rods and forms a resettable rotatable connection through a torsion spring design. The support plate is tilted in its normal state.

[0011] Preferably, a support rod located below the support plate is fixedly connected to the upper surface of the base plate, a spring rod is fixedly connected to the lower surface of the extension plate at one end of the middle set of cutters, a pressure block is fixedly connected to the bottom end of the spring rod, and a support rod is fixedly connected to the upper surface of the base plate.

[0012] Preferably, clamping mechanisms for clamping and fixing cables are installed on both sides of the cutting assembly. A mounting plate is fixedly connected to one side surface of the base plate. One set of clamping mechanisms is fixedly installed on the surface of the mounting plate. The bottom end of another set of clamping mechanisms is fixedly connected to a movable block that is slidably connected to the base plate. Two sets of second springs, which are fixedly connected to a set of support blocks, are fixedly connected to one side surface of the movable block. Two sets of dovetail blocks are fixedly connected to the lower surface of the movable block. A dovetail groove matching the dovetail blocks is opened on the surface of the base plate.

[0013] Preferably, a straightening component is movably provided between one set of the support blocks and the movable blocks. A lifting mechanism for driving the cutting component to move up and down is installed on the upper surface of the base plate. The lifting mechanism includes two sets of movable plates. The top of the second piston rod is fixedly connected to the bottom of the movable plate. A sliding rod is movably sleeved on one set of the movable plates, and a threaded rod is threadedly sleeved on the other set of the movable plates. A fixing plate is fixedly connected above both sets of movable plates, and a crossbar for mounting the cutter is fixedly connected between the two sets of fixing plates.

[0014] Preferably, a collection box is fixedly installed on the upper surface of the base plate below one end of the support plate. The collection box is L-shaped, and the cut cable can fall directly into the collection box for collection.

[0015] Compared with related technologies, the positioning mechanism for a thread cutting machine provided by this utility model has the following advantages:

[0016] This utility model provides a positioning mechanism for a wire cutting machine. The cutting component is driven to move downward by a lifting mechanism to cut the cable. During the movement of the cutting component, the limiting block on the movable block is released by the setting of the straightening component. The movable block is driven to move by the elastic force of the second spring. In conjunction with the clamping mechanism, the cable to be cut is straightened. This reduces the error caused by the cable bending at the moment of cutting to a certain extent, thereby improving the accuracy of the cable cutting and facilitating subsequent processing.

[0017] This utility model provides a positioning mechanism for a wire cutting machine. After the cable is cut, the cutting assembly is reset under the drive of the lifting mechanism. At this time, the pressure block cancels the downward force on the support plate, and the support plate is reset and tilted under the action of the torsion spring. The cable falls directly into the collection box for collection under the action of gravity, which reduces the workload of the staff to a certain extent. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Depend on Figures 1-7 As shown, this utility model includes a base plate 1, a positioning plate 12 for positioning the cable is fixedly connected to the upper surface of the base plate 1, and clamping mechanisms 5 for clamping and fixing the cable are installed on both sides of the cutting component 4 (this is a conventional technical means, and its principle will not be described in detail). A mounting plate 15 is fixedly connected to one side surface of the base plate 1, a set of clamping mechanisms 5 is fixedly installed on the surface of the mounting plate 15, and a movable block 61 that is slidably connected to the bottom end of another set of clamping mechanisms 5 is fixedly connected to the base plate 1.

[0028] Place one end of the cable against the positioning plate 12, and then use two sets of clamping mechanisms 5 to clamp and fix the cable to be cut, thereby fixing the position of the cable and facilitating precise cutting. Note that the clamping mechanism 5 adopts the existing conventional cable clamping arm structure, and its detailed principle will not be elaborated here.

[0029] Furthermore, a lifting mechanism 2 is installed on the upper surface of the base plate 1 to drive the cutting component 4 to move up and down. The lifting mechanism 2 includes two sets of movable plates 21. One set of movable plates 21 is movably sleeved with a slide rod 23, which is fixedly installed on the upper surface of a set of support blocks 13. The other set of movable plates 21 is threadedly sleeved with a threaded rod 22, which is movably connected to the upper surface of another set of support blocks 13. The bottom end of the threaded rod 22 is connected to a drive motor fixedly installed inside the other set of support blocks 13 through a coupling. By starting the drive motor, the threaded rod 22 is driven to rotate. The threaded rod 22 can drive the movable plate 21 to move up and down by cooperating with the slide rod 23. A fixed plate 24 is fixedly connected above both sets of movable plates 21. A crossbar 25 for mounting the cutter 41 is fixedly connected between the two sets of fixed plates 24. The cutting component 4 on the crossbar 25 can be raised and lowered by the movable plate 21 cooperating with the fixed plate 24.

[0030] Support blocks 13 are symmetrically fixedly connected to the upper surface of the base plate 1. Two sets of second springs 62, which are fixedly connected to one set of support blocks 13, are fixedly connected to one side surface of the movable block 61. Two sets of dovetail blocks 611 are fixedly connected to the lower surface of the movable block 61. The surface of the base plate 1 is provided with dovetail grooves that match the dovetail blocks 611. The mutual cooperation between the dovetail blocks 611 and the dovetail grooves facilitates the parallel movement of the movable block 61.

[0031] A straightening assembly 6 is movably provided between a set of support blocks 13 and a movable block 61. The straightening assembly 6 includes a limiting block 65 located above the second spring 62 (the limiting block 65 has a slope a on one side, and the movable block 61 in contact with the limiting block 65 has a matching slope a on one side). The position of the movable block 61 can be limited by the limiting block 65. Two sets of second piston cylinders 66 are installed inside the set of support blocks 13 (the support blocks 13 have a cavity, and the second piston cylinders 66 and the drive motor are installed inside the cavity). The inner walls of the two sets of second piston cylinders 66 are movably fitted with second piston rods 67 extending to the upper end of the support blocks 13. The second piston rods 67 are fixedly connected to the movable plate 21. The upper surface of the bottom plate 1 is symmetrically fixedly connected with first piston cylinders 63. The inner walls of the first piston cylinders 63 are movably fitted with first piston rods 64 fixedly connected to both ends of the limiting block 65. A connecting pipe 68 is fixedly connected between the second piston cylinders 66 and the first piston cylinders 63.

[0032] Furthermore, during the descent of the lifting mechanism 2, the movable plate 21 drives the two sets of second piston rods 67 to move downwards. The second piston rods 67 compress the gas inside the second piston cylinder 66, and the gas inside the second piston cylinder 66 is transmitted to the inside of the first piston cylinder 63 through the connecting pipe 68. At this time, the first piston rod 64 pushes out from the inside of the first piston cylinder 63, and the first piston rod 64 drives the limiting block 65 to move upwards. Through the cooperation of the inclined surfaces of the limiting block 65 and the movable block 61, and the sliding of the movable block 61 under the action of the second spring 62, the cable can be straightened by the clamping mechanism 5, which facilitates the precise cutting of the cable. When the movable plate 21 is reset, the negative pressure drives the first piston rod 64 to move downwards, driving the limiting block 65 to reset. Through the setting of the inclined surface a, the limiting block 65 can move between the support block 13 and the movable block 61 to limit the movable block 61.

[0033] A cutting assembly 4 for cutting cables is installed on the upper surface of the base plate 1. The cutting assembly 4 includes three sets of cutters 41 for cutting cables. Two sets of connecting blocks 45 are fixedly connected to both sides of one set of cutters 41. A pressure plate 44 for squeezing and limiting the cable is provided below each set of connecting blocks 45 (the height of the pressure plate 44 is lower than the height of the cutter 41). An arc-shaped groove is opened on the lower surface of the pressure plate 44 (to increase the contact area between the pressure plate 44 and the cable and improve the positioning effect). An insert rod 47 that moves and passes through the top of each set of pressure plates 44 is fixedly connected to the top of each set of pressure plates 44. A first spring 46 that is fixedly connected to the pressure plate 44 and the insert rod 47 is sleeved on the outer wall of the insert rod 47. A support rod 14 located below the support plate 31 is fixedly connected to the upper surface of the base plate 1. A spring rod 42 is fixedly connected to the lower surface of the extension plate at one end of the cutter 41. A pressure block 43 is fixedly connected to the bottom end of the spring rod 42. A support rod 14 is fixedly connected to the upper surface of the base plate 1. When the lifting mechanism 2 drives the cutting assembly 4 to descend, the spring rod 42 and the pressure block 43 press the support plate 31. When the bottom end of the support plate 31 contacts the top end of the support rod 14, the support plate 31 is in a parallel state. The pressure plate 44 presses the cable. When the cutter 41 does not contact the cable, the first spring 46 on the pressure plate 44 is pressed. The setting of the insertion rod 47 facilitates the limiting of the pressure plate 44. The lifting mechanism 2 continues to descend, and the cable can be cut into multiple sections by the three sets of cutters 41. This facilitates the simultaneous cutting of multiple sets of cables and improves work efficiency.

[0034] Below the cutting assembly 4 is a feeding assembly 3 for collecting the cut cables. The feeding assembly 3 includes a support plate 31 located below the cutting assembly 4. The upper end of the support plate 31 has three sets of through slots 33 corresponding to the cutter 41. The upper end of the support plate 31 has three sets of through slots 33 corresponding to the cutter 41. The upper end of the base plate 1 is fixedly connected to two sets of fixing rods 32. The support plate 31 is rotatably mounted on the side wall of the fixing rods 32 and forms a resettable rotatable connection through a torsion spring design (torsion springs are existing technology and will not be described in detail here). The support plate 31 is tilted in its normal state.

[0035] A collection box 11 is fixedly installed on the upper surface of the base plate 1 below one end of the support plate 31. The collection box 11 is L-shaped, and the cut cable can fall directly into the collection box 11 for collection (a partition can be installed inside the collection box 11 to facilitate the separation of the cut cable).

[0036] Finally, after the cable is cut, the lifting mechanism 2 drives the cutting assembly 4 to move upward (at this time, the clamping mechanism 5 cancels the clamping of the cable), the pressure block 43 cancels the downward force on the support plate 31, and the support plate 31 is reset under the action of the torsion spring. At this time, the support plate 31 is in an inclined state, and the cut cable falls to the inner wall of the collection box 11 for collection under the action of gravity, thus completing the cutting operation.

[0037] Working principle: When the cable needs to be cut, one end of the cable is brought into contact with the positioning plate 12. The cable is clamped and fixed by two sets of clamping mechanisms 5. Then, the fixed plate 24 is moved by the movable plate 21 through the cooperation of the threaded rod 22 and the sliding rod 23. The fixed plate 24, together with the crossbar 25, drives the cutting assembly 4 to descend. When the cutter 41 in the cutting assembly 4 descends, the spring rod 42 and the pressure block 43 apply downward pressure to the support plate 31. When the support plate 31 contacts the support rod 14, the support plate 31 is in a parallel state. Then, the pressure plate 44 descends to the appropriate position and, together with the horizontal support plate 31, squeezes and fixes the cable. At the same time, as the movable plate 21 moves downward, it applies downward pressure to the second piston rod 67. 67. The air inside the second piston cylinder 66 is transferred to the first piston cylinder 63 through the connecting pipe 68. At this time, the first piston rod 64 is pushed out, and the limiting block 65 moves upward under the action of the first piston rod 64, releasing the limitation on the movable block 61. The movable block 61 moves to the left under the action of the second spring 62, and straightens the cable by cooperating with the clamping mechanism 5. Finally, the cable is cut by the continuing to descending cutter 41. After the cutting is completed, the lifting mechanism 2 drives the cutting assembly 4 to reset. At this time, the clamping mechanism 5 releases the clamp on the cable, the pressure block 43 moves upward, and the force on the support plate 31 is released. The support plate 31 resets under the action of the torsion spring and tilts to one side. The cut cable falls into the collection box 11 for collection under the action of gravity, completing the operation.
