Description

Technical Field

[0001] This utility model relates to an eccentric locking motor wire repair clamp. Background Technology

[0002] Currently, during the welding process of motor stators, due to welding technology or material issues, some weld points may have defects such as incomplete welds or missing welds, requiring repair welding. During repair welding, the wire to be repaired must be accurately fixed in the designated position to prevent weld failure due to wire movement.

[0003] Existing wire clamping tools are mostly simple clamps or tweezers. These tools require continuous gripping force and cannot achieve automatic locking. Operators need to hold the clamp with one hand while performing soldering operations with the other, which is labor-intensive and inefficient.

[0004] After searching the existing technology, it was found that Chinese patent CN218137397U discloses a special wire cutting pliers for repairing the welding of multi-layer flat wires in motor stators. This patent focuses on the cutting function of the welding points and cannot achieve the clamping and fixing of the wires. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an eccentric locking motor wire repair clamp that can achieve stable clamping to simplify the welding operation.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: an eccentric locking type motor wire repair clamp, comprising:

[0007] Mounting base;

[0008] The first clamping arm has its proximal end fixed to the mounting base and its distal end provided with a first clamping part.

[0009] The second clamping arm has its distal end hinged to the distal end of the first clamping arm, and its proximal end located within the mounting base. The second clamping arm is provided with a second clamping portion corresponding to the first clamping portion.

[0010] A spring is disposed within a mounting base, with its two ends respectively abutting against the proximal ends of a first clamping arm and a second clamping arm.

[0011] A locking mechanism is rotatably mounted on a mounting base. The locking mechanism is adapted to clamp the wire by rotating and pressing the second clamping arm, thereby causing the first clamping arm and the second clamping arm to move closer to each other and clamping the wire in the clamping space formed between the first clamping part and the second clamping part.

[0012] Furthermore, the first clamping part includes a first clamping groove disposed on the inner side of the first clamping arm, and the second clamping part includes a second clamping groove disposed on the inner side of the second clamping arm. The first clamping groove and the second clamping groove are disposed opposite to each other to form a clamping space.

[0013] Furthermore, the locking mechanism includes an eccentric locking block rotatably mounted on a mounting base, the eccentric portion of which is adapted to compress the second clamping arm during rotation.

[0014] Furthermore, a specific type of eccentric locking block is provided, wherein the eccentric locking block is an eccentric wheel or a cam.

[0015] Furthermore, the eccentric locking block is provided with an operating handle, which extends radially along the eccentric locking block.

[0016] Furthermore, the mounting base includes an upper mounting base and a lower mounting base, which are fixedly connected by fasteners, and the proximal ends of the first clamping arm and the second clamping arm are located between the upper mounting base and the lower mounting base.

[0017] Furthermore, a spring receiving groove is provided on the lower mounting base, and the spring is disposed in the spring receiving groove.

[0018] Furthermore, the mounting base is provided with multiple mounting holes;

[0019] The first clamping arm is provided with a fixing hole corresponding to the mounting hole of the mounting base;

[0020] The first clamping arm is adapted to be fixed to the mounting base by means of fasteners passing through the mounting hole and the fixing hole.

[0021] Furthermore, the distal end of the first clamping arm is hinged to the distal end of the second clamping arm via a hinge shaft.

[0022] By adopting the above technical solution, this utility model has the following beneficial effects:

[0023] In this invention, during use, the wire to be welded is placed in the clamping space formed between the first clamping part and the second clamping part. At this time, the two ends of the spring abut against the proximal ends of the first clamping arm and the second clamping arm, respectively, so that the first clamping arm and the second clamping arm are in a naturally open state. Rotating the locking mechanism causes the locking mechanism to rotate and compress the second clamping arm, overcoming the spring force and pushing the proximal end of the second clamping arm closer to the proximal end of the first clamping arm. Since the distal end of the second clamping arm is hinged to the distal end of the first clamping arm, when the proximal ends of the second and first clamping arms approach each other, the tendency for the distal ends of the second and first clamping arms to separate is constrained by the hinge, thereby causing the first and second clamping arms to approach each other, reducing the clamping space formed between the first and second clamping parts and clamping the wire, thus completing the fixation of the wire. The clamping is achieved by rotating and pressing the locking mechanism. The operation is continuous and the clamping state can be maintained, which solves the problem that the existing technology requires continuous external force to maintain clamping. At the same time, the first clamping arm is fixed on the mounting base, and the second clamping arm is supported by a spring. With the rotation and locking of the locking mechanism, a stable clamping structure is formed, which ensures that the position of the wire does not shift during the welding process.

[0024] In summary, this utility model uses a first clamping arm fixed to the mounting base, and a second clamping arm supported by a spring and hinged to the first clamping arm. A rotatable locking mechanism presses the second clamping arm to achieve clamping and maintain a locked state. This solves the problems in existing technologies where continuous external force is required to maintain clamping and where unstable clamping leads to wire displacement. Furthermore, the eccentric locking block, multiple mounting holes, and grooved joints enhance the reliability and adaptability of the clamping mechanism, meeting the requirements for wire fixation in motor repair welding operations.

[0028] 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.

[0029] like Figure 1-3As shown, an eccentric locking type motor wire repair clamp includes:

[0030] Mounting base 1;

[0031] The first clamping arm 2 has its proximal end fixed to the mounting base 1, and its distal end is provided with a first clamping part 21.

[0032] The second clamping arm 3 has its distal end hinged to the distal end of the first clamping arm 2, and its proximal end located inside the mounting base 1. The second clamping arm 3 is provided with a second clamping part 31 corresponding to the first clamping part 21.

[0033] Spring 4 is disposed in mounting base 1, and the two ends of spring 4 abut against the proximal ends of the first clamping arm 2 and the second clamping arm 3, respectively.

[0034] The locking mechanism 5 is rotatably mounted on the mounting base 1. The locking mechanism 5 is adapted to squeeze the second clamping arm 3 by rotating it, thereby causing the first clamping arm 2 and the second clamping arm 3 to move closer to each other, so that the clamping space formed between the first clamping part 21 and the second clamping part 31 clamps the wire.

[0035] In this embodiment, as Figure 1-2 As shown, in use, the wire to be welded is placed in the clamping space formed between the first clamping part 21 and the second clamping part 31. At this time, the two ends of the spring 4 abut against the proximal ends of the first clamping arm 2 and the second clamping arm 3, respectively, so that the first clamping arm 2 and the second clamping arm 3 are in a naturally open state. Rotating the locking mechanism 5, the locking mechanism 5 squeezes the second clamping arm 3 by rotating, overcoming the elastic force of the spring 4, and pushes the proximal end of the second clamping arm 3 closer to the proximal end of the first clamping arm 2. Since the distal end of the second clamping arm 3 is hinged to the distal end of the first clamping arm 2, when the proximal end of the second clamping arm 3 and the proximal end of the first clamping arm 2 approach each other, the tendency of the distal end of the second clamping arm 3 and the distal end of the first clamping arm 2 to separate from each other is constrained by the hinge, thereby driving the first clamping arm 2 and the second clamping arm 3 to approach each other, so that the clamping space formed between the first clamping part 21 and the second clamping part 31 is reduced and the wire is clamped, thus completing the fixation of the wire. The clamping is achieved by the rotation and compression of the locking mechanism 5. The operation is continuous and the clamping state can be maintained, which solves the problem that the existing technology requires continuous external force to maintain clamping. At the same time, the first clamping arm 2 is fixed on the mounting base 1, and the second clamping arm 3 is supported by the spring 4. With the rotation and locking of the locking mechanism 5, a stable clamping structure is formed, which ensures that the position of the wire does not shift during the welding process.

[0036] Specifically, such as Figure 1-2As shown, the first clamping part 21 includes a first clamping groove 22 disposed on the inner side of the first clamping arm 2, and the second clamping part 31 includes a second clamping groove 32 disposed on the inner side of the second clamping arm 3. The first clamping groove 22 and the second clamping groove 32 are disposed opposite to each other to form a clamping space.

[0037] Specifically, such as Figure 1-2 As shown, the locking mechanism 5 includes an eccentric locking block 51, which is rotatably mounted on the mounting base 1. The eccentric portion of the eccentric locking block 51 is adapted to press the second clamping arm 3 when rotating.

[0038] Specifically, such as Figure 2 As shown, the eccentric locking block 51 is an eccentric wheel.

[0039] Specifically, such as Figure 2 As shown, the eccentric locking block 51 is provided with an operating handle 52, which extends radially along the eccentric locking block 51.

[0040] In this embodiment, as Figure 1-2 As shown, the eccentric locking block 51 is rotatably connected to the mounting base 1 via a rotating shaft. The axis of the rotating shaft does not coincide with the geometric center of the eccentric locking block 51, forming an eccentric structure. When the eccentric locking block 51 rotates, the distance between the eccentric part and the axis of the rotating shaft changes. When the operating handle 52 drives the eccentric locking block 51 to rotate to the position where the eccentric part is furthest from the axis of the rotating shaft, the eccentric part applies the maximum compression stroke to the second clamping arm 3, pushing the proximal end of the second clamping arm 3 closer to the proximal end of the first clamping arm 2, so that the first clamping part 21 and the second clamping part 31 clamp the wire. When the operating handle 52 is rotated to make the eccentric part move away from this position, the elastic force of the spring 4 pushes the proximal end of the second clamping arm 3 to return to its original position, and the first clamping arm 2 and the second clamping arm 3 open, releasing the wire. In this embodiment, the eccentric locking block 51 is an eccentric wheel, and the outer circumferential surface of the eccentric wheel serves as the contact surface for compressing the second clamping arm 3, with a large contact area. In other embodiments, the eccentric locking block 51 can also be a cam.

[0041] One end of the operating handle 52 is fixed to the eccentric locking block 51, and the other end extends radially outward from the eccentric locking block 51. When operating, force is applied by holding the extended end of the operating handle 52. The length of the operating handle 52 forms a lever arm, which converts the operating force into a torque that drives the eccentric locking block 51 to rotate. The longer the length of the operating handle 52, the greater the torque generated by the same operating force, and the smaller the operating force required to rotate the eccentric locking block 51.

[0042] Specifically, such as Figure 1 As shown, the mounting base 1 includes an upper mounting base 11 and a lower mounting base 12. The upper mounting base 11 and the lower mounting base 12 are fixedly connected by fasteners. The proximal ends of the first clamping arm 2 and the second clamping arm 3 are located between the upper mounting base 11 and the lower mounting base 12.

[0043] Specifically, such as Figure 1-2 As shown, a spring receiving groove 13 is provided on the lower mounting base 12, and the spring 4 is disposed in the spring receiving groove 13.

[0044] Specifically, such as Figure 1-3 As shown, the mounting base 1 has multiple mounting holes 14;

[0045] The first clamping arm 2 is provided with fixing holes corresponding to the mounting holes 14 of the mounting base 1;

[0046] The first clamping arm 2 is adapted to be fixed to the mounting base 1 by means of fasteners passing through the mounting hole 14 and the fixing hole.

[0047] Specifically, such as Figure 1 As shown, the distal end of the first clamping arm 2 is hinged to the distal end of the second clamping arm 3 via a hinge shaft.

[0048] In this embodiment, as Figure 1-2 As shown, an accommodating space is formed between the upper mounting base 11 and the lower mounting base 12. The proximal ends of the first clamping arm 2 and the second clamping arm 3 are placed in this accommodating space. After the upper mounting base 11 and the lower mounting base 12 are connected by bolts or other fasteners, the proximal end of the first clamping arm 2 is clamped and fixed, while providing a space for movement for the proximal end of the second clamping arm 3. The proximal end of the second clamping arm 3 can move in the compression direction of the spring 4 within this accommodating space. A spring receiving groove 13 is provided on the lower mounting base 12. The depth and width of the spring receiving groove 13 are adapted to the size of the spring 4. One end of the spring 4 is placed at the bottom of the spring receiving groove 13 and abuts against the proximal end of the first clamping arm 2, and the other end abuts against the proximal end of the second clamping arm 3. The spring receiving groove 13 radially limits the spring 4 to prevent the spring 4 from shifting laterally during compression or release.

[0049] The mounting base 1 has a plurality of mounting holes 14 spaced apart along the length of the first clamping arm 2. The first clamping arm 2 has fixing holes corresponding to the positions of the mounting holes 14. Fasteners pass through the mounting holes 14 and fixing holes in sequence to fix the first clamping arm 2 onto the mounting base 1.

[0050] The hinge shaft passes through the hinge holes on the distal ends of the first clamping arm 2 and the second clamping arm 3. The distal ends of the first clamping arm 2 and the second clamping arm 3 rotate relative to each other around the hinge shaft. The hinge shaft provides a fixed rotation center for the relative movement of the first clamping arm 2 and the second clamping arm 3. When the proximal end of the second clamping arm 3 moves towards the proximal end of the first clamping arm 2 under the pressure of the eccentric locking block 51, the second clamping arm 3 rotates around the hinge shaft, causing the second clamping part 31 to move closer to the first clamping part 21. The hinge shaft constrains the rotation of the first clamping arm 2 and the second clamping arm 3, so that the clamping action is performed along a predetermined trajectory.

[0051] 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.
