Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically to a connecting wire cutting fixture. Background Technology

[0002] Connecting wires are the lines used in circuit board manufacturing to connect electronic components to conductors on the circuit board through methods such as crimping or soldering. The lengths of connecting wires used in circuit connection vary, requiring a cutter to trim them. A fixture is also needed to position the connecting wire during cutting; a connecting wire cutting fixture is a specialized tool or device used to cut connecting wires.

[0003] A search revealed that patent application number CN202122594654.X discloses a wire cutting fixture, including a rectangular base; a rectangular module positioning strip welded to the base and positioned in the middle; a module fixed to the top of the module positioning strip, the module's shape and size matching the module positioning strip; and a long, narrow slide rail welded to the base and positioned at its edge. Beneficial effects: The fixture features a reasonable and simple structure, low production cost, convenient and simple use, complete functions, high precision in wire harness trimming, stable quality, high production efficiency, and low labor costs. When trimming wire harnesses, the fixture effectively fixes the connector to the fixture, effectively controlling the stability of the wire harness. The blade fixing block effectively secures the blade, and the fixing block, mounted on the slide rail, exerts a force on the blade during core wire trimming, reducing the risk of scratching connectors and incomplete trimming during manual trimming.

[0004] The current fixtures used for cutting connecting wires simply serve to fix the connecting wires in place, and are mostly fixed to the workbench. This design has certain drawbacks. When the connecting wire is cut, the blade has a certain thickness, and the two ends of the connecting wire are squeezed by the blade. If the position between them is fixed, the connecting wire will bend and deform under the squeezing force, affecting the appearance of the cut connecting wire and causing the end of the connecting wire to be bent, which is not convenient for subsequent use in connecting circuits. Therefore, we need to propose a connecting wire cutting fixture. Utility Model Content

[0005] The purpose of this utility model is to provide a connecting wire cutting fixture. Through the design of a movable cutting fixture, during the cutting process of the connecting wire, the two ends of the connecting wire are separated under the pressure of the cutter. Since the connecting wire is clamped on the cutting fixture, the compressed connecting wire can drive the two cutting fixtures to move away from each other, preventing the connecting wire ends from being squeezed and deformed, ensuring the aesthetics of the cut connecting wire, and not affecting the connection of subsequent application circuits, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a connecting wire cutting fixture, including a worktable, wherein two grooves are provided on the worktable, and a set of wire cutting fixtures for clamping the connecting wires are slidably installed inside each groove, and a spring is connected between one end of the wire cutting fixture and the inner wall of the groove.

[0007] The tangent fixture includes a base that is slidably installed inside a groove and a top plate that can be lifted and lowered above the base. A lifting mechanism for driving the top plate to rise and fall is installed on the base.

[0008] The top surface of the base has a first V-shaped groove for installing anti-slip ridges on the inner wall, and the bottom of the top plate has a second V-shaped groove for installing anti-slip ridges on the inner wall. The first V-shaped groove and the second V-shaped groove are aligned.

[0009] Preferably, a slider is installed at the bottom of the base, and a groove is formed at the bottom of the groove, and the slider is slidably installed inside the groove.

[0010] Preferably, each of the two sets of bases has a limit strip connected to one end facing the other, and the limit strips on the two sets of bases are staggered.

[0011] Preferably, one end of one set of top plates is provided with a slot, and one end of the other set of top plates is connected to a limiting post, which is movably inserted into the slot.

[0012] Preferably, a support plate is installed on the workbench between two sets of tangent fixtures, and the support plate has a blade groove for the cutting blade to penetrate deeper.

[0013] Preferably, the base has a receiving groove, and the lifting mechanism includes a bidirectional lead screw rotatably installed inside the receiving groove, with two opposing lead screw seats threadedly connected to the outer wall of the bidirectional lead screw.

[0014] Preferably, a motor is installed at one of the opposite ends of the two bases, the output shaft of the motor is connected to one end of a bidirectional lead screw, a fixing plate is connected to the bottom of the top plate, and a rotatably connected connecting rod is connected between the bottom of the fixing plate and the two lead screw seats.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the design of a movable wire cutting fixture, separates the two sections of the connecting wire under the pressure of the cutter during the cutting process. Since the connecting wire is clamped on the wire cutting fixture, the squeezed connecting wire can drive the two wire cutting fixtures to move away from each other, preventing the connecting wire sections from being squeezed and deformed, ensuring the aesthetics of the cutting connecting wire, and not affecting the connection of subsequent application circuits.

[0017] 2. This utility model uses the base and top plate together, and both the base and top plate are provided with V-shaped grooves with anti-slip convex strips on the inner wall to position the connecting wire, so that it will not shift during the cutting process and ensure the cutting effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a connecting wire cutting fixture, including a workbench 1, on which two grooves 2 are provided, the two grooves 2 are symmetrically arranged about the center of the workbench 1, and a set of wire cutting fixtures 3 for clamping the connecting wire are slidably installed inside each groove 2. The two wire cutting fixtures 3 are respectively clamped at both ends of the connecting wire to increase the stability of the connecting wire when cutting. A spring 4 is connected between one end of the wire cutting fixture 3 and the inner wall of the groove 2.

[0024] When the connecting wire is cut, the cut end of the connecting wire is squeezed by the cutter. In order to prevent the cutting end of the connecting wire from deforming or bending, the cutting fixture 3 moves closer to the spring 4, thereby squeezing the spring 4, causing the spring 4 to deform and be compressed. After the cutting is completed, the spring 4 returns to its original shape and pushes the cutting fixture 3 to reset.

[0025] The tangent fixture 3 includes a base 31 that is slidably installed inside the groove 2 and a top plate 36 that can be lifted and lowered above the base 31. The base 31 and the top plate 36 have the same length and width. A lifting mechanism 6 that drives the top plate 36 to lift and lower is installed on the base 31. There are four lifting mechanisms 6 arranged in a matrix. Two lifting mechanisms 6 are installed on each base 31, and the four lifting mechanisms 6 operate synchronously.

[0026] The top surface of the base 31 has a first V-shaped groove 33 with anti-slip raised strips installed on its inner wall, and the bottom of the top plate 36 has a second V-shaped groove 37 with anti-slip raised strips installed on its inner wall. The first V-shaped groove 33 and the second V-shaped groove 37 are aligned. The connecting wire is snapped between the first V-shaped groove 33 and the second V-shaped groove 37, and the V-shaped design of the groove can accommodate connecting wires of various diameters.

[0027] A slider 34 is installed at the bottom of the base 31, and a groove 21 is provided at the bottom of the groove 2. The slider 34 is slidably installed inside the groove 21 to ensure the stability of the movement of the tangent fixture 3.

[0028] Each of the two sets of bases 31 has a limit bar 35 connected to one end of its opposite side. The limit bars 35 on the two sets of bases 31 are staggered to further improve the stability of the movement of the tangent fixture 3.

[0029] One end of one set of top plates 36 has a slot, and one end of the other set of top plates 36 is connected to a limiting post 38. The limiting post 38 is movably inserted into the slot, which facilitates relative displacement between the two top plates 36.

[0030] A support plate 5 is installed on the workbench 1 between two sets of tangent fixtures 3. The support plate 5 has a blade groove 51 for the cutting blade to penetrate. The cutting blade assembly (not shown in the figure) is located above the support plate 5, and the cutting blade is aligned with the blade groove 51.

[0031] The base 31 has a receiving groove 32. The lifting mechanism 6 includes a bidirectional lead screw 62 that is rotatably installed inside the receiving groove 32. Two opposing lead screw seats 63 are threadedly connected to the outer wall of the bidirectional lead screw 62.

[0032] Motors 61 are installed at opposite ends of the two bases 31. The output shaft of the motors 61 is connected to one end of the bidirectional lead screw 62. A fixing plate 65 is connected to the bottom of the top plate 36. A rotatably connected connecting rod 64 is connected between the bottom of the fixing plate 65 and the two lead screw seats 63.

[0033] By driving the bidirectional lead screw 62 to rotate via the motor 61, the two lead screw seats 63 can move towards or away from each other, thereby raising or lowering the fixed plate 65, which in turn raises or lowers the top plate 36.

[0034] In use, the lifting mechanism 6 first lifts the top plate 36 to facilitate the installation of multiple connecting wires. The connecting wires are then passed between the base 31 and the top plate 36 and placed inside the first V-groove 33. Then, the motor 61 in the lifting mechanism 6 is run again. The motor 61 drives the bidirectional lead screw 62 to rotate. The bidirectional lead screw 62 drives the two lead screw seats 63 to move away from each other, causing the two connecting rods 64 to rotate and the included angle between the two connecting rods 64 to increase. This, in turn, drives the top plate 36 to move down through the fixing plate 65 until the connecting wires are clamped between the first V-groove 33 and the second V-groove 37, ensuring the stability of the connecting wires.

[0035] Then the drive cutter (not shown in the figure) moves down to cut the connecting wire. During the cutting process, the cross-section of the connecting wire is squeezed by the cutter. The connecting wire drives the two cutting fixtures 3 to move away from each other (a short distance), and the slider 34 moves inside the slide groove 21. The spring 4 is compressed to protect the end of the connecting wire and prevent the end of the connecting wire from being squeezed and deformed or bent.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
