Description
Technical Field
[0001] This utility model relates to a spring-loaded self-locking motor wire repair clamp. Background Technology
[0002] Currently, during the welding process of flat wires in motor stators, it is often necessary to repair poorly welded joints. During this repair welding, the internal wires of the motor need to be fixed and clamped to ensure accurate and stable welding placement.
[0003] After searching the existing technology, it was found that Chinese patent CN218137397U discloses a special wire cutting pliers for repairing the welding joints of multilayer flat wires in motor stators. However, this technology mainly solves the problem of wire cutting and is not suitable for clamping and fixing wires during welding. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a spring self-locking motor wire repair welding clamp, which can fix the wire in the motor wire repair welding process.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a spring-loaded self-locking motor wire repair clamp, comprising:
[0006] A base, wherein a sliding groove is provided on the base and a limiting plate is provided on one side of the base;
[0007] A slider, which is slidably disposed within the groove;
[0008] The lower clamping rod is fixed on the base and has a clamping part, which has a clamping groove suitable for accommodating the wire.
[0009] An upper clamping rod is mounted on a slider, and the upper clamping rod is provided with a clamping part that cooperates with the clamping part of the lower clamping rod;
[0010] A spring, one end of which abuts against the slider and the other end against the limiting plate of the base, is adapted to drive the pressing part of the upper clamping rod to clamp the wire in the clamping groove.
[0011] Furthermore, in order to fix the lower clamping rod on the base, the base is provided with a mounting hole, and the lower clamping rod is provided with a fixing hole corresponding to the mounting hole. The lower clamping rod is adapted to be fixed on the base by fasteners passing through the fixing hole and the mounting hole.
[0012] Furthermore, in order to limit the position of the spring, the slider is provided with a receiving groove corresponding to the position of the spring.
[0013] Furthermore, a guide hole is provided on the limiting plate;
[0014] The spring-locking motor wire repair clamp also includes a spring limiting mechanism, which includes a guide rod, one end of which is adapted to pass through a guide hole and be mounted on the limiting plate;
[0015] The spring is adapted to be sleeved on the guide rod and located between the limiting plate and the slider.
[0016] Furthermore, the end of the guide rod away from the upper clamping rod is provided with a threaded hole;
[0017] The spring limiting mechanism also includes a fixing member, which is adapted to be threadedly connected to the threaded hole of the guide rod to fix the guide rod on the limiting plate.
[0018] Furthermore, the base is provided with a limiting groove, the slider is provided with a first positioning hole, and the upper clamping rod is provided with a second positioning hole. The limiting groove is adapted to accommodate a limiting pin that passes through the first positioning hole and the second positioning hole in sequence to limit the sliding stroke of the slider.
[0019] Furthermore, the clamping groove is a V-shaped groove or a U-shaped groove.
[0020] By adopting the above technical solution, this utility model has the following beneficial effects:
[0021] In this invention, during use, the operator pushes the slider to overcome the spring force and slide it away from the lower clamping rod along the slide groove. This causes the clamping part of the upper clamping rod mounted on the slider to separate from the clamping groove of the lower clamping rod, forming an opening gap. After the operator releases the pushing force on the slider, the slider slides down the slide groove towards the lower clamping rod under the elastic pushing force of the spring. This causes the clamping part of the upper clamping rod to gradually approach and clamp the wire in the clamping groove. The other end of the spring abuts against the limiting plate of the base, providing continuous pushing force to the slider, thus clamping and fixing the wire. After the welding operation is completed, the slider is pushed again to overcome the spring force, causing the clamping part to separate from the clamping groove and moving the lower clamping rod away from the wire position. The spring connects the slider and the limiting plate to form an elastic drive mechanism. The clamping force is applied by the elastic force of the spring, and the clamping state of the wire can be maintained without the need for an additional locking device. This achieves a rapid clamping and releasing operation process, shortening the clamping time.
[0022] In summary, this utility model has a reasonable structure. It achieves elastic clamping of the wire through the cooperation of the spring, slider, and limiting plate. It is easy to operate, reliable in clamping, and suitable for fixing the wire in the process of repairing and welding motor wires. Attached Figure Description

[0026] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0027] like Figure 1-3 As shown, a spring-loaded self-locking motor wire repair clamp includes:
[0028] Base 1, with a sliding groove 11 on the base 1 and a limiting plate 12 on one side of the base 1;
[0029] Slider 2 is slidably disposed within slide groove 11;
[0030] The lower clamping rod 3 is fixed on the base 1. The lower clamping rod 3 is provided with a clamping part 31, and the clamping part 31 is provided with a clamping groove 32 suitable for accommodating the wire.
[0031] Upper clamping rod 4 is mounted on slider 2 and has a pressing part 41 that cooperates with the clamping part 31 of lower clamping rod 3.
[0032] Spring 5, one end of spring 5 abuts against slider 2, and the other end abuts against limiting plate 12 of base 1. Spring 5 is adapted to drive the pressing part 41 of upper clamping rod 4 to clamp the wire in clamping groove 32.
[0033] In this embodiment, as Figure 1 As shown, during use, the operator pushes the slider 2 to overcome the elastic force of the spring 5 and slides it away from the lower clamping rod 3 along the slide groove 11. This causes the pressing part 41 of the upper clamping rod 4 installed on the slider 2 to separate from the clamping groove 32 of the clamping part 31 of the lower clamping rod 3, forming an opening gap. After the operator releases the pushing force on the slider 2, the slider 2 slides along the slide groove 11 towards the lower clamping rod 3 under the elastic pushing force of the spring 5. This causes the pressing part 41 of the upper clamping rod 4 to gradually approach and clamp the wire in the clamping groove 32. The other end of the spring 5 abuts against the limiting plate 12 of the base 1 to provide continuous pushing force to the slider 2, thereby clamping and fixing the wire. After the welding operation is completed, the slider 2 is pushed again to overcome the elastic force of the spring 5, causing the pressing part 41 to separate from the clamping groove 32, and the lower clamping rod 3 is moved away from the wire position. The spring 5 connects the slider 2 and the limiting plate 12 to form an elastic drive mechanism. The spring 5 applies clamping force, and the wire can be held in place without the need for an additional locking device. This achieves a quick clamping and releasing operation, shortening the clamping time.
[0034] Specifically, such as Figure 2 As shown, the base 1 has a mounting hole 13, and the lower clamping rod 3 has a fixing hole 33 corresponding to the mounting hole 13. The lower clamping rod 3 is adapted to be fixed on the base 1 by fasteners passing through the fixing hole 33 and the mounting hole 13.
[0035] In this embodiment, as Figure 2 As shown, the mounting hole 13 of the base 1 corresponds to the fixing hole 33 of the lower clamping rod 3. Fasteners pass through the fixing hole 33 and the mounting hole 13 in sequence, and the lower clamping rod 3 is locked onto the base 1 by threaded engagement. When it is necessary to replace the lower clamping rod 3 with a different specification, the lower clamping rod 3 can be removed from the base 1 by loosening the fasteners, and then re-secured with the fasteners after replacement. In this embodiment, the fastener is a bolt and nut combination; in other embodiments, the fastener can also be a screw or other detachable connector.
[0036] Specifically, such as Figure 3 As shown, the slider 2 is provided with a receiving groove 14 corresponding to the position of the spring 5.
[0037] In this embodiment, as Figure 1-2 As shown, the slider 2 has a receiving groove 14, the position of which corresponds to the position of the spring 5. The receiving groove 14 radially constrains the end of the spring 5, so that the axial direction of the spring 5 is consistent with the extension direction of the groove 11 during compression and extension, thus preventing the spring 5 from shifting laterally and causing uneven force on the slider 2.
[0038] Specifically, such as Figure 2 As shown, a guide hole 15 is provided on the limiting plate 12;
[0039] The spring-locking motor wire repair clamp also includes a spring limiting mechanism, which includes a guide rod 71. One end of the guide rod 71 is adapted to pass through the guide hole 15 and be installed on the limiting plate 12.
[0040] The spring 5 is adapted to be sleeved on the guide rod 71 and located between the limiting plate 12 and the slider 2.
[0041] Specifically, such as Figure 2 As shown, the end of the guide rod 71 away from the upper clamping rod 4 is provided with a threaded hole;
[0042] The spring limiting mechanism also includes a fixing member 73, which is adapted to be threadedly connected to the threaded hole of the guide rod 71 to fix the guide rod 71 on the limiting plate 12.
[0043] In this embodiment, as Figure 1-2As shown, one end of the guide rod 71 passes through the guide hole 15 on the limiting plate 12, and the end of the guide rod 71 away from the upper clamping rod 4 is provided with a threaded hole. The fixing member 73 is threadedly connected to the threaded hole of the guide rod 71, and the fixing member 73 presses against the outer side of the limiting plate 12, locking the guide rod 71 onto the limiting plate 12. The spring 5 is sleeved on the guide rod 71, with one end abutting against the slider 2 and the other end abutting against the limiting plate 12. The guide rod 71 provides axial positioning for the spring 5, allowing the spring 5 to move along the axis of the guide rod 71 during extension and retraction, ensuring that the direction of the thrust applied by the spring 5 to the slider 2 is parallel to the extension direction of the slide groove 11. In this embodiment, the fixing member 73 is a nut. In other embodiments, the fixing member 73 can also be a baffle with a threaded hole or other locking member with threaded engagement function.
[0044] Specifically, such as Figure 2 As shown, the base 1 is provided with a limiting groove 16, the slider 2 is provided with a first positioning hole 21, and the upper clamping rod 4 is provided with a second positioning hole 42. The limiting groove 16 is adapted to accommodate the limiting pin passing through the first positioning hole 21 and the second positioning hole 42 in sequence to limit the sliding stroke of the slider 2.
[0045] In this embodiment, as Figure 2 As shown, the limiting pin passes sequentially through the second positioning hole 42 of the upper clamping rod 4 and the first positioning hole 21 of the slider 2. Both ends of the limiting pin are accommodated within the limiting groove 16 of the base 1. The limiting groove 16 is provided along the extending direction of the slide groove 11, and its length limits the movement range of the limiting pin. When the slider 2 slides along the slide groove 11, the limiting pin moves synchronously with the slider 2. When the limiting pin moves to the end of the groove within the limiting groove 16, it abuts against the end wall of the limiting groove 16, preventing the slider 2 from continuing to slide, thereby limiting the maximum sliding distance of the slider 2 and preventing the slider 2 from dislodging from the slide groove 11.
[0046] Specifically, such as Figure 1 As shown, the clamping groove 32 is a V-shaped groove.
[0047] In this embodiment, as Figure 1 As shown, the clamping groove 32 is formed on the clamping part 31 of the lower clamping rod 3 to accommodate the motor wire. In this embodiment, the clamping groove 32 is a V-shaped groove. The two inclined surfaces of the V-shaped groove form two line contacts with the circular cross-section wire. When the pressing part 41 of the upper clamping rod 4 presses the wire, the wire is radially positioned within the V-shaped groove, preventing the wire from rotating or shifting laterally during clamping. In other embodiments, the clamping groove 32 can also be a U-shaped groove. The arc-shaped bottom surface of the U-shaped groove fits against the circular outer surface of the wire, increasing the contact area.
[0048] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
