Description

Technical Field

[0001] This utility model belongs to the field of jigs and fixtures, and particularly relates to a wire fixing mechanism. Background Technology

[0002] Currently, the processing of standard-sized wires mostly uses automated or semi-automated equipment for pre-fabrication and assembly. Standardized fixtures enable rapid positioning and fixing of the wires, thereby ensuring high production efficiency and consistency.

[0003] However, in actual production, there are often processing requirements for products with special dimensions. Because the length of each wire varies, the conventional method of preparing a whole row of wires cannot be used; instead, wires of different lengths must be prepared individually. In existing technology, the fixture only has a limiting strip at the front, which is then fixed in place after the entire row of wires has been laid out. Before placement, the limiting strip needs to be opened. When manually placing the wires of varying lengths into the fixture one by one, the lack of a limiting strip and effective fixing structure makes the wires prone to popping out after placement. This not only requires operators to expend a lot of effort repeatedly adjusting the wire positions, resulting in extremely high labor intensity, but also makes the operation cumbersome and time-consuming, seriously affecting production efficiency. Furthermore, because the wires are not securely fixed, they are prone to displacement during subsequent processing, making it difficult to guarantee the assembly accuracy of the product and leading to inconsistent product quality. Utility Model Content

[0004] The purpose of this invention is to provide a wire fixing mechanism to overcome at least one of the above-mentioned defects in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides a wire fixing mechanism, including a base, a torsion spring, a first shaft, a second shaft, and a fixing arm. The base has a plurality of insertion holes spaced apart along its length. Each insertion hole has an accommodating space above it. The first shaft and the second shaft are fixed inside the base. Both the first shaft and the second shaft pass through the accommodating space. Each accommodating space is provided with a torsion spring and a fixing arm. The fixing arm is rotatably connected to the first shaft. The torsion spring is fixedly sleeved on the second shaft. The bottom end of the fixing arm extends into the insertion hole. One end of the torsion spring abuts against the base, and the other end of the torsion spring abuts against the fixing arm.

[0007] Preferably, the base includes a first base and a second base. The top of the first base is detachably connected to the second base. The first base is provided with a plurality of first slots spaced apart along its length. The second base is provided with a plurality of second slots spaced apart along its length. The first slots and the second slots enclose and form an insertion hole. An accommodating space is provided in the second base and communicates with the second slots.

[0008] Preferably, the base further includes a third seat, which is detachably connected to the top of the second seat and located behind the accommodating space. There is a channel between the third seat and the second seat, and one end of the torsion spring is inserted into the channel and abuts against the bottom wall of the third seat.

[0009] Preferably, the first slot has an observation hole located behind the first slot.

[0010] Preferably, the first seat is equipped with a baffle strip, which is located behind the observation hole.

[0011] Preferably, the top of the fixed arm passes through the receiving space and extends beyond the base.

[0012] Preferably, the fixed arm includes a mounting section, an extension section, and a fixing section. The mounting section is rotatably connected to the first shaft. The top of the mounting section is connected to the extension section, the top end of the extension section passes through the accommodating space and extends to the outside of the base. The bottom of the mounting section is connected to the fixing section, the bottom end of the fixing section extends into the insertion hole, and the rear sidewall of the fixing section abuts against one end of the torsion spring.

[0013] Preferably, the bottom of the fixed section has teeth arranged in an arc shape.

[0014] Preferably, it also includes a mounting base, to which the base is detachably connected.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Automatic fixing is achieved through the linkage of torsion spring and fixed arm, which is suitable for special size wires and automated production lines. It has the characteristics of simple structure, convenient maintenance and high precision, which significantly improves product yield while improving efficiency and reducing costs.

[0017] 2. The first and second slots are manufactured separately, which can effectively control the surface polishing during processing and avoid the problem of insufficient polishing inside the slots caused by one-piece processing, which would lead to wire scratches. This ensures the integrity and surface quality of the wire and provides a high-quality material foundation for subsequent production.

[0018] 3. The observation hole makes it easy to see whether the wire is inserted in place.

[0019] 4. Control the insertion length using a stop bar to ensure uniform wire insertion length.

[0020] 5. The arrangement of the arc-shaped teeth not only ensures that the fixed section can be pushed backward when the wire is inserted, but also improves the stability of the wire. Attached Figure Description

Detailed Implementation

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0029] Contents not described in detail in this specification are existing technologies known to those skilled in the art. In the description of this utility model, it should be understood that terms such as "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this utility model and simplifying the description.

Furthermore, terms such as "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figures 1 to 6As shown, the wire fixing mechanism provided in this embodiment includes a base 5, a torsion spring 1, a first shaft 2, a second shaft 3, and a fixing arm 4. The base 5 is provided with a plurality of insertion holes 6 at intervals along its length. The base 5 above each insertion hole 6 has an accommodating space 8. The first shaft 2 and the second shaft 3 are fixed inside the base 5. The first shaft 2 is located in front of the second shaft 3. Both the first shaft 2 and the second shaft 3 pass through the accommodating space 8. The torsion spring 1 and the fixing arm 4 are provided in each accommodating space 8. The fixing arm 4 is rotatably connected to the first shaft 2. The torsion spring 1 is fixedly sleeved on the second shaft 3. The bottom end of the fixing arm 4 extends into the insertion hole 6. The rear end of the torsion spring 1 abuts against the base 5, and the front end of the torsion spring 1 abuts against the fixing arm 4. In use, align the cable with the socket 6, then push the cable backward to insert it into the socket 6. During the insertion process, push the lower part of the fixing arm 4 to swing backward, compressing the torsion spring 1. After insertion, release the cable, the torsion spring 1 returns to its original position, and the lower part of the fixing arm 4 swings forward to press the cable, thus automatically fixing it. In this embodiment, the cable is inserted into the socket 6 by a robotic arm. When it is necessary to unlock and remove the cable as a whole, a mechanical device, such as a cylinder combined with a push plate, can be used to push the upper part of all the fixing arms 4 forward, causing the lower part of the fixing arms 4 to swing backward away from the cable, allowing the cable to be removed as a whole. After the cable is removed, remove the pushing force on the upper part of the fixing arm 4, and the fixing arm 4 will return to its original position under the action of the torsion spring 1.

[0031] This wire fixing mechanism, through the linkage design of torsion spring 1 and fixing arm 4, achieves automatic fixing upon wire insertion, avoiding the tedious process of repeated manual adjustments. When the wire is inserted into the socket 6, the cooperation between fixing arm 4 and torsion spring 1 can respond quickly and accurately lock the wire, ensuring that each wire is in the predetermined position. The high fixing accuracy effectively improves the accuracy and stability of wire positioning, providing a reliable foundation for subsequent processing.

[0032] Each wire can be independently and automatically secured, a feature that prevents the already positioned wires from shifting during the placement process. There's no need to worry about the stability of the placed wires, resulting in a smoother operation and significantly improved convenience and efficiency. Furthermore, this mechanism is also suitable for wires of different lengths and specifications, effectively solving the problem of securing special-sized wires in existing technologies.

[0033] The wires can be inserted into socket 6 via a robotic arm, and then removed entirely using a combination of cylinders and push plates. This design is perfectly suited for automated production lines, reducing manual intervention and labor costs, while significantly shortening the time for wire fixing and disassembly, thus improving production efficiency. Compared to the traditional method of manually placing each wire into the fixture one by one, this mechanism enables batch and rapid operation, meeting the needs of high-efficiency production in modern manufacturing.

[0034] The mechanism is mainly composed of basic components such as base 5, torsion spring 1, first shaft 2, second shaft 3, and fixed arm 4. Its simple structural design and small number of parts reduce manufacturing difficulty and cost. Furthermore, the connection and cooperation methods between the components are mature and stable, making malfunctions less likely. Daily maintenance is simple and easy, effectively reducing equipment maintenance costs and downtime, and improving equipment lifespan and production continuity.

[0035] The stable and reliable wire fixing effect avoids processing errors caused by wire displacement, ensures the accuracy and consistency of product assembly, and thus significantly reduces the product defect rate.

[0036] The base 5 includes a first base 51 and a second base 52. The top of the first base 51 is detachably connected to the second base 52. The first base 51 has a plurality of first slots 53 spaced apart along its length, and the second base 52 has a plurality of second slots 54 spaced apart along its length. The first slots 53 and the second slots 54 together form an insertion hole 6. An accommodating space 8 is disposed in the second base 52 and communicates with the second slots 54. The first slots 53 and the second slots 54 are processed separately. During processing, the surface polishing can be effectively controlled, avoiding the problem of insufficient polishing inside the slots caused by one-piece processing, which would lead to wire scratches. This ensures the integrity and surface quality of the wire and provides a high-quality material foundation for subsequent production.

[0037] The base 5 also includes a third seat 55, which is detachably connected to the top of the second seat 52 and located behind the accommodating space 8. A channel 56 is provided between the third seat 55 and the second seat 52. The rear end of the torsion spring 1 is inserted into the channel 56 and abuts against the bottom wall of the third seat 55. This detachable third seat 55 design facilitates the installation of the torsion spring 1 and provides a limiting wall to ensure that the torsion spring 1 stably provides effective torque, while also improving the convenience of assembly and maintenance of the mechanism.

[0038] The first slot 51 has an observation hole 57 located behind the first slot 53. The observation hole 57 allows for easy observation of whether the wire is inserted correctly, and the wire fixing mechanism can be removed for inspection if any problems occur.

[0039] The first housing 51 is equipped with a stop bar 58, which is located behind the observation hole 57. The stop bar 58 controls the insertion length to ensure that the wire insertion length is uniform.

[0040] The top of the fixed arm 4 passes through the accommodating space 8 and extends beyond the base 5, making it easy to push the fixed arm 4 when unlocking.

[0041] The fixed arm 4 includes a mounting section 41, an extension section 42, and a fixing section 43. The mounting section 41 is rotatably connected to the first shaft 2. The top of the mounting section 41 is connected to the extension section 42, the top of which passes through the accommodating space 8 and extends to the outside of the base 5. The bottom of the mounting section 41 is connected to the fixing section 43, the bottom of which extends into the insertion hole 6. The rear sidewall of the fixing section 43 abuts against the front end of the torsion spring 1. When unlocking, pushing the extension section 42 forward causes the mounting section 41 to rotate around the first shaft 2, thereby causing the fixing section 43 to swing backward, compressing the front end of the torsion spring 1.

[0042] The bottom of the fixing section 43 has teeth 44 arranged in an arc shape. The arrangement of the teeth 44 in an arc shape not only ensures that the fixing section 43 can swing backward when the wire is inserted, but also improves the fixing stability of the wire.

[0043] This includes a mounting base 7, to which the base 5 is detachably connected. The mounting base 7 can be installed at the required work location, and bases of different sizes can be installed on the mounting base 7 to adapt to different work requirements.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
