Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal wire processing, in particular to a welding fixture for metal guide wires. Background Art
[0002] In the production of metal conductor products, the welding process for metal guide wires and spring tubes requires the use of a fixture. The portion of the fixture that holds the metal guide wire is inlaid with copper, which improves welding quality. However, each time the copper wears out, it needs to be removed and replaced with a new piece for maintenance. Because the copper is embedded in the fixture, removing it is inconvenient. Utility Model Content
[0003] The purpose of the utility model is to provide a welding fixture for a metal guide wire, so as to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0004] The technical solution adopted to solve the above technical problems is as follows: a welding fixture for a metal guide wire, comprising: a base; a first clamp, installed on the base, the first clamp having an installation groove, a first inlay being accommodated in the installation groove, a first elastic member being installed between the bottom wall of the installation groove and the first inlay, the first elastic member providing elastic force to extend the first inlay out of the installation groove, the first clamp having a first fixing member installed thereon for fixing the first inlay, the first inlay having a first welding groove; a second clamp, slidably connected to the first clamp, a receiving groove being provided through the second clamp, a second inlay being accommodated in the receiving groove, the second clamp having a second fixing member installed thereon for fixing the second inlay, a second welding groove being provided on the side of the second inlay close to the first inlay, and when the first clamp and the second clamp slide relative to each other and fit together, the first welding groove and the second welding groove are connected to form a total welding groove.
[0005] This technical solution has at least the following beneficial effects: when the first inlay and the second inlay need to be replaced, the first fixing member and the second fixing member can be loosened, and the first inlay can be ejected from the installation slot under the elastic force of the first elastic member, so that the first inlay can be easily removed and replaced, and the other end of the second inlay can be pushed through the penetrating receiving slot to facilitate the removal and replacement of the second inlay, thereby improving maintenance efficiency.
[0006] As a further improvement to the above technical solution, the first fixing member is a first screw, which is threadedly connected to the first clamping member, and one end of the first screw presses against the first inlay. By tightening the first screw, the end of the first screw presses against the first inlay, thereby confining the first inlay within the installation slot. By loosening the first screw, the first screw no longer confines the first inlay, thereby facilitating removal and replacement of the first inlay.
[0007] As a further improvement to the above technical solution, the second fixing member is a second screw, which is threadedly connected to the second clamping member, and one end of the second screw presses against the second inlay. By tightening the second screw, the one end of the second screw presses against the second inlay, thereby confining the second inlay within the receiving groove. By loosening the second screw, the second screw no longer confines the second inlay, thereby facilitating removal and replacement of the second inlay.
[0008] As a further improvement to the above technical solution, the first clamp is slidably connected to the base, the base is equipped with a stopper, and the end of the first clamp away from the second clamp abuts against the stopper. The original bolt fixing structure is eliminated, which can facilitate the assembly of the first clamp and simplify the installation process.
[0009] As a further improvement of the above technical solution, the base is provided with a guide slider, and the first clamp is provided with a guide slot adapted to slide with the guide slider, thereby ensuring the sliding stability of the base and the first clamp.
[0010] As a further improvement to the above technical solution, a second elastic member is installed between the first and second clamps to provide a spring force to separate the first and second clamps. When the driver pushes the second clamp to slide relative to the first clamp, the second elastic member can be used to separate the second clamp from the first clamp when the second clamp is released, automatically opening the first and second inlays, facilitating the next welding process and placing the metal guide wire in the main welding groove.
[0011] As a further improvement to the above technical solution, the first clamping member defines a first clearance groove corresponding to the first welding groove, and the second clamping member defines a second clearance groove corresponding to the second welding groove. When the first clamping member slides relative to and fits with the second clamping member, the first clearance groove and the second clearance groove connect to form a main clearance groove. The diameter of the main clearance groove is larger than that of the main welding groove, making it easier to place the metal guide wire into the main welding groove.
[0012] As a further improvement to the above technical solution, first welding grooves are defined on both sides of the first inlay, and second welding grooves are defined on both sides of the second inlay. Both the first and second inlays can be removed and replaced with the first and second welding grooves on the other side to clamp and weld the metal guide wire, thereby increasing the utilization of the first and second inlays and reducing production costs.
[0013] As a further improvement of the above technical solution, the first clamp is equipped with a bolt pin, and the bolt pin passes through the second clamp. The second clamp can slide stably relative to the first clamp under the guidance of the bolt pin.
[0014] As a further improvement to the above technical solution, the main welding groove is offset from the center of the side where the first and second clamps meet. If the first and second welding grooves were located in the middle of the first and second clamps, respectively, during welding, the metal guide wire would need to follow a U-shaped path when placing it. However, with this technical solution, the positioning is adjusted to allow only a straight "U" path on one side to reach the welding groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Reference Figure 1-3 The welding fixture for the metal guide wire includes a base 100, a first clamp 200 and a second clamp 300. The first clamp 200 is in a square shape and has a mounting groove 210 on one side. The length and width of the opening of the mounting groove 210 are both smaller than the length and width of the side of the first clamp 200 where the mounting groove 210 is located. The mounting groove 210 does not pass through the first clamp 200. A first inlay 220 is accommodated inside the mounting groove 210. The first inlay 220 can be completely placed in the mounting groove 210 so that one side of the first inlay 220 is flush with one side of the first clamp 200. Two first welding grooves 221 are provided side by side on both sides of the first inlay 220. The internal space of the first welding groove 221 is semi-cylindrical as a whole and both ends pass through the first inlay 220. When the first inlay 220 is embedded in the mounting groove 210, the side with the first welding groove 221 is flush with the side of the first clamp 200 where the mounting groove 210 is located.
[0025] The first clamp 200 is mounted with a first fixing member that secures the first inlay 220 within the mounting slot 210, preventing the first inlay 220 from detaching from the mounting slot 210. The first fixing member is a first screw 240. A countersunk threaded hole connected to the mounting slot 210 is defined on one side of the first clamp 200. The first screw 240 is threaded into the countersunk threaded hole and presses against the surface of the first inlay 220, securing the first inlay 220 within the mounting slot 210.
[0026] A first elastic member 230 is installed between the first clamp 200 and the first inlay 220. The first elastic member 230 provides the elastic force that extends the first inlay 220 out of the mounting slot 210. Specifically, two grooves are defined in the bottom wall of the mounting slot 210. The first elastic member 230 is a first coil spring. One end of each first coil spring is embedded in the corresponding groove, and the other end abuts against the side wall of the first inlay 220.
[0027] Among them, the shortest length of the first coil spring after compression is less than the depth of the groove, and the original length of the first coil spring when not compressed is greater than the depth of the groove, so that after the first screw 240 is loosened, under the action of the elastic restoring force of the first coil spring, one end of the first inlay 220 can be pushed out of the opening of the installation groove 210, thereby facilitating the removal of the first inlay 220.
[0028] In other embodiments, the first fixing member can also be a first blocking block slidably installed on the first clamp 200 along a depth direction perpendicular to the mounting groove 210. The first blocking block can be moved to a position that blocks or does not block the opening of the mounting groove 210. When installing the first inlay 220, the first blocking block can be first moved to a position that does not block the opening of the mounting groove 210, and then the first inlay 220 can be extended into the mounting groove 210, and then the first blocking block can be moved to a position that blocks the opening of the mounting groove 210, thereby preventing the first inlay 220 from leaving the mounting groove 210 and installing the first inlay 220 in the mounting groove 210.
[0029] The second clamp 300 is block-shaped and has a receiving slot 310 defined on one side. The two ends of the receiving slot 310 extend through the second clamp 300. A second inlay 320 is provided on the second clamp 300. The second inlay 320 is embedded in the receiving slot 310, with the two ends of the second inlay 320 aligned with the ends of the second clamp 300.
[0030] The second clamping member 300 is mounted with a second fixing member that secures the second inlay 320 in the receiving groove 310, preventing the second inlay 320 from falling out of the receiving groove 310. The second fixing member is a second screw 340. The second clamping member 300 defines a countersunk threaded hole that communicates with the receiving groove 310. One end of the second screw 340 is threaded into the countersunk threaded hole of the second clamping member 300 and presses against the second inlay 320, thereby confining the second inlay 320 in the receiving groove 310.
[0031] Two second welding grooves 321 are defined on both ends of the second inlay 320, flush with the second clamp 300. The interior of the second welding grooves 321 is semi-cylindrical, with both ends extending through the second inlay 320. When the first clamp 200 and the second clamp 300 slide relative to each other until they are in contact, the first welding grooves 221 and the second welding grooves 321 fit together to form a cylindrical main welding groove 330, which allows for the insertion of a guidewire for welding.
[0032] The second clamp 300 is mounted on the output end of the connecting rod pressing and ejecting rod device, with the base 100 fixed. By driving the connecting rod pressing and ejecting rod device, the second clamp 300 moves relative to the first clamp 200, achieving relative movement between the first clamp 200 and the second clamp 300, meeting the welding requirements. The first and second screws 240, 340 can be disassembled and assembled to respectively disassemble the first and second inlays 220, 320. The provision of the first elastic member 230 also facilitates replacement of the first inlay 220, ensuring good welding performance while optimizing the welding process and adding consumable replacement devices. The first inlay 220 and the second inlay 320 are both pure copper blocks, and four first welding grooves 221 and second welding grooves 321 are respectively provided on the first inlay 220 and the second inlay 320. By disassembling and assembling the first inlay 220 and the second inlay 320, replacing the first welding grooves 221 and / or the second welding grooves 321 on different sides to cooperate with each other to form a new total welding groove 330, the utilization rate of the first inlay 220 and the second inlay 320 can be improved and the production cost can be reduced.
[0033] In order to facilitate the installation of the first clamp 200 on the base 100 , two guide sliders 400 are provided on one side of the base 100 and are distributed parallel to each other in the length direction. The guide sliders 400 and the base 100 are integrally formed.
[0034] Both sides of the guide slider 400 are provided with a fixing groove with a triangular cross-section, and one side of the first clamp 200 is provided with a guide groove 410 that is compatible with the guide slider 400 with the fixing groove. The guide slider 400 is embedded in the guide groove 410 and can slide in the guide groove 410.
[0035] The base 100 is provided with a protruding stopper 420. The length direction of the stopper 420 is perpendicular to the length direction of the guide slider 400, and the ends of the stopper 420 are respectively connected to the guide slider 400 on the same side, so that the two guide sliders 400 and the stopper 420 form a U-shaped structure. In other words, the two guide sliders 400, the stopper 420, and the base 100 are integrally formed.
[0036] When the guide slider 400 completely slides into the guide slot 410, the side of the first clamp 200 away from the second clamp 300 contacts the stop block 420, that is, the stop block 420 can provide support for the first clamp 200 to ensure that the position of the first clamp 200 is fixed.
[0037] In other embodiments, the cross section of the guide slider 400 may also be dovetail-shaped or T-shaped, so that the guide slider 400 cannot directly escape from the middle of the fixing groove.
[0038] A second elastic member 430 is installed between the first clamp 200 and the second clamp 300. This second elastic member 430 is a second coil spring. A circular hole is defined on the side of the first clamp 200 near the second clamp 300, and one end of the second coil spring is secured within the circular hole. When the first clamp 200 and the second clamp 300 overlap to form the main welding groove 330, the second coil spring is compressed and accommodated within the circular hole. When the second clamp 300 moves away from the first clamp 200, the elastic restoring force of the second coil spring assists in separating the first and second clamps 200 and prevents the first clamp 200 from moving with the second clamp 300, thereby ensuring the positional stability of the first clamp 200. This also facilitates the next welding process, where the metal guide wire to be welded is placed between the first and second welding grooves 221 and 321.
[0039] The first clamping member 200 defines two first paving grooves 500 , and the positions of the two first paving grooves 500 are respectively corresponding to the positions of the two first welding grooves 221 .
[0040] The internal space of the first clearance groove 500 is semi-cylindrical as a whole. The semi-cylindrical diameter of the internal space of the first clearance groove 500 is larger than the semi-cylindrical diameter of the internal space of the first welding groove 221, and the semi-cylindrical axis of the internal space of the first clearance groove 500 coincides with the semi-cylindrical axis of the internal space of the first welding groove 221.
[0041] The second clamping member 300 defines two second paving grooves 510 , and the positions of the two second paving grooves 510 are respectively corresponding to the positions of the two second welding grooves 321 .
[0042] The internal space of the second clearance groove 510 is semi-cylindrical as a whole. The semi-cylindrical diameter of the internal space of the second clearance groove 510 is larger than the semi-cylindrical diameter of the internal space of the second welding groove 321, and the semi-cylindrical axis of the internal space of the second clearance groove 510 coincides with the semi-cylindrical axis of the internal space of the second welding groove 321.
[0043] When the first clamp 200 and the second clamp 300 are covered with each other, the first welding groove 221 and the second welding groove 321 are adapted to each other to form a total welding groove 330, and the first make way groove 500 and the second make way groove 510 are adapted to each other to form a total make way groove 520. The internal space of the total make way groove 520 is cylindrical as a whole and corresponds to the position of the total welding groove 330.
[0044] A bolt pin 600 is threadedly installed on the first clamp 200 at a position avoiding the installation groove 210. The end wall of the bolt pin 600 passes through the second clamp 300, and the second clamp 300 can slide relative to the bolt pin 600, thereby serving as a guide for the relative sliding of the first clamp 200 and the second clamp 300.
[0045] When the first clamp 200 and the second clamp 300 overlap, the main welding groove 330 is located at the edge of the side where the first clamp 200 and the second clamp 300 are attached to each other, so that the main welding groove 330 is located in the middle of the side where the first clamp 200 and the second clamp 300 overlap each other. If the first welding groove and the second welding groove were located in the middle of the side of the first clamp and the second clamp, respectively, during welding, the metal guide wire would need to be placed in a U-shaped path. However, after the position adjustment of the present technical solution, only a "U"-shaped straight path is required on one side to reach the welding groove.
[0046] The four corners of the base 100 are provided with long strip-shaped bolt holes, through which bolt rods can be inserted, so that the base 100 can be fixed on the rack of the equipment.
[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
