Description

Technical Field

[0001] This invention belongs to the field of electrical connector manufacturing technology, specifically relating to an automatic clamping device for multiple wire springs simultaneously in a wire spring hole assembly machine. Background Technology

[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.

[0003] In high-end fields such as electronic equipment, communication systems, and aerospace, electrical connectors are core components for achieving circuit connections, and their reliability directly affects the operational stability of the entire system. Spring-loaded sockets, as a type of highly reliable insertion assembly on electrical connectors, are widely used in various demanding scenarios due to their advantages such as low contact resistance, long insertion / removal life, and vibration resistance.

[0004] The full name of the wire spring hole is a single-leaf hyperboloid wire spring socket. Its core structure consists of multiple elastic metal wires (usually gold-plated or silver-plated to improve conductivity and corrosion resistance) arranged according to the straight generatrix pattern of a single-leaf hyperboloid within the hole. The assembly of the wire spring hole requires multiple processes. Among them, the wire spring hole assembly machine is the key equipment for completing the initial assembly of the front sleeve, inner sleeve, and wire spring wires. The precise fixing and loosening of the wire spring wires is the core link for achieving high-quality assembly with the wire spring hole assembly machine. If the wire spring wires are not reliably fixed or are subjected to uneven force, it will directly cause the wire spring wire arrangement to deviate from the design trajectory, thus affecting the assembly accuracy of the subsequent front sleeve and inner sleeve, and ultimately reducing the contact stability and service life of the wire spring hole.

[0005] In existing technologies, for spring holes with a small number of spring wires, clamping plates are often used to fix and loosen them. However, when the number of spring wires is large (e.g., 12 or more) and the diameter of the spring hole is small, the clamping plate structure has obvious limitations: on the one hand, it is difficult for the clamping plate to make uniform contact with multiple spring wires at the same time, which can easily lead to uneven distribution of fixing force and affect the accuracy of spring wire arrangement; on the other hand, the installation space of the clamping plate is limited in the small-diameter scenario, and its structural dimensions are difficult to adapt, which may cause operational interference or ineffective clamping, seriously restricting the processing efficiency and product quality of multiple small-diameter spring holes. Summary of the Invention

[0006] To address the technical problems mentioned in the background section, this invention provides an automatic clamping device for multiple spring wires simultaneously in a single-stage spring wire assembly machine.

[0014] Furthermore, the lower end of the fixing seat is provided with a boss, and the base plate is provided with a recess, the boss and the recess cooperate with each other; it also includes a fourth locking screw for fixing the fixing seat, the fixing seat is fixed to the base plate by the fourth locking screw for fixing the fixing seat.

[0016] Furthermore, the circumference of the wire spring fixing rod is provided with multiple grooves, and one end of the wire spring fixing rod is a regular polygon, with each side of the regular polygon being tangent to the center of the groove.

[0017] Furthermore, the left end of the clamping sleeve is provided with a plurality of slots, the same number as the grooves, and the slots are evenly distributed along the circumference; the left end of the clamping sleeve has a tapered shape, and the left end hole of the sliding member has a tapered shape, the tapered shape of the left end of the clamping sleeve is consistent with the tapered shape of the left end hole of the sliding member; the clamping sleeve is also provided with cylindrical pin holes and square pin holes.

[0018] Furthermore, the slider is cylindrical in the middle and cuboid on both sides; the fixed base has a rectangular hole, and the cuboid part of the slider mates with the rectangular hole; the slider has a roller position and a shaft hole, and also includes a round shaft and a roller, with the roller installed in the shaft hole through the round shaft.

[0019] Furthermore, the surface of the push block that contacts the roller is provided with steps and slopes.

[0020] Furthermore, the fixed base is provided with a spring fixing recess, the sliding member is provided with a recess, one end of the return spring is located in the spring fixing recess, and the other end is located in the recess of the sliding member; it also includes a cylindrical pin and a square pin, the cylindrical pin passes through the cylindrical pin hole of the clamping sleeve to fix the wire spring fixing rod to the clamping sleeve, and the square pin passes through the square pin hole of the baffle and the square pin hole of the clamping sleeve to fix the clamping sleeve to the baffle.

[0021] Compared with the prior art, the present invention provides an automatic clamping device for multiple wire springs simultaneously in a wire spring hole assembly machine, which has the following advantages:

[0022] (1) In this invention, the spring wires are pre-threaded into the groove of the fixing rod to ensure the initial uniformity of the arrangement. When the conical hole of the sliding member presses against the conical surface of the clamping sleeve, the left end of the slotted clamping sleeve contracts synchronously, which can simultaneously apply uniform compressive force to all the spring wires, avoiding the problem of uneven force when the clamping plate fixes multiple spring wires. It achieves simultaneous clamping of 12 or more spring wires with uniform distribution of fixing force, ensuring that the arrangement accuracy of the spring wires meets the design requirements of a single-leaf hyperboloid.

[0023] (2) The tapered shrinkage structure fixes the wire spring through internal compression. Compared with the external clamping plate, it occupies less space and can be operated within the limited space of the small-diameter wire spring hole. The cooperation between the sliding part and the rectangular hole of the fixed seat further ensures the compactness of the structure. It breaks through the space limitation of the small-diameter wire spring hole, and does not need to rely on a large clamping plate, realizing reliable clamping and loosening in small-size scenarios.

[0024] (3) Using a cylinder as a power source provides a stable driving force, ensuring that the clamping force is controllable; when the cylinder resets, the return spring drives the sliding part to retract, causing the clamping sleeve to loosen the spring wire. The whole process does not require manual intervention and the action response is rapid. It replaces manual or manual operation, improves the efficiency of fixing and loosening the spring wire, and avoids errors caused by human operation, thus improving the reliability of the processing process.

[0025] (4) The slotted design of the clamping sleeve makes it elastic, allowing it to naturally spring back to its original position after the tapered compression disappears; the cylindrical pin and square pin ensure that the relative positions of the fixing rod and the clamping sleeve, and the clamping sleeve and the baffle are fixed, avoiding positional shifts after multiple operations. This achieves stable and repeatable fixing and loosening of the wire spring, meets the needs of multiple clamping and adjustment during the processing and assembly of the wire spring hole, and extends the service life of the device.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Please see Figure 1 and Figure 2The present invention provides an automatic clamping device for multiple wire springs in a wire spring hole assembly machine, comprising a cylinder (1), a cylinder fixing plate (3), a fixing seat (4), a base plate (5), a baffle (6), a wire spring fixing rod (11), a clamping sleeve (12), a sliding member (14), a pushing block (17), and a return spring (19).

[0044] The fixed seat (4) is fixed on the base plate (5), the cylinder fixing plate (3) is fixed on the fixed seat (4), and the cylinder (1) is fixed on the cylinder fixing plate (3).

[0045] The baffle (6) is fixed on the fixed base (4), the clamping sleeve (12) passes through the baffle (6), the wire spring fixing rod (11) is located inside the clamping sleeve (12), and the circumference of the wire spring fixing rod (11) is provided with a groove, and the wire spring (8) passes through the groove.

[0046] The sliding member (14) is located inside the fixed seat (4) and cooperates with the clamping sleeve (12). The pushing block (17) is connected to the cylinder (1) and contacts the sliding member (14).

[0047] One end of the reset spring (19) is connected to the fixed base (4), and the other end is connected to the sliding member (14).

[0048] Power is provided by the cylinder (1), the reset spring (19) resets, and the taper of the sliding part (14) and the clamping sleeve (12) is used to simultaneously clamp and release the wire spring.

[0049] In one specific embodiment, the overall appearance structure of the automatic clamping device for multiple spring wires simultaneously in a single assembly machine for spring holes is as follows: Figure 1 As shown, the cylinder (1) mainly provides power for clamping. It is mounted on the cylinder fixing plate (3) and locked by the third locking screw (9). The shaft end of the cylinder (1) is connected to a clamping part.

[0050] There are four first locking screws (2), which are used to lock and fix the cylinder fixing plate (3) and the fixing seat (4).

[0051] The cylinder mounting plate (3) has a cylinder mounting threaded hole. The cylinder (1) is fixed by screwing the third locking screw (9) into the threaded hole. It also has a through hole for the first locking screw (2). The shape is as follows. Figure 3 As shown.

[0052] The mounting base (4) has through holes and guide rails for placing other parts. It is fixed to the base plate (5) by the fourth locking screw (10). The lower end has a boss that cooperates with the recess on the base plate (5) to make it more secure.

[0053] All of these devices are fixed on the base plate (5).

[0054] baffle (6), such as Figure 4 As shown, the baffle has a second locking screw (7) screw through hole (20), a cylindrical pin (13) clamping sleeve through hole (21), a square pin hole (22) between the clamping sleeve and the baffle, and a step that mates with the fixing seat (4). The square pin hole (22) and the clamping sleeve through hole (21) are connected to each other, which can achieve the function of fixing the clamping sleeve.

[0055] The second locking screw (7), a total of 4 pieces, is used to lock and fix the baffle (6) to the fixing seat (4).

[0056] In one specific embodiment, the device can clamp 12 spring wires simultaneously, and the 12 spring wires are evenly distributed in a circle.

[0057] The third locking screw (9), a total of 4 pieces, is used to fix the cylinder (1) on the cylinder fixing plate (3).

[0058] Please refer to the exploded diagram. Figure 2 The internal structure and connection relationship of the parts can be clearly distinguished. Among them, there are two fourth locking screws (10). The wire spring fixing rod (11) is small in size and is circular. It has protrusions at the top and bottom for fixing. There are 12 grooves in the circumference. The wire spring passes through these grooves. The left end of the wire spring fixing rod is a dodecagon. The size of the dodecagon is smaller than the circumference. Each side is tangent to the center of the groove. Figure 5 and Figure 6 As shown. The purpose of making one end of the wire spring fixing rod into a dodecagon is to provide space for the compression sleeve to contract when it shrinks.

[0059] The clamping sleeve (12) has an inner hole that matches the shape of the wire spring fixing rod (11) and fits tightly. The left end of the clamping sleeve has 12 slots (23), which are evenly distributed circumferentially and form a 15-degree angle with the wire spring groove on the wire spring fixing rod (11). After slotting, the clamping teeth on the left end of the clamping sleeve become elastic. The left end of the clamping sleeve has a tapered design, matching the tapered shape of the left end hole of the sliding part (14), used to compress and reduce the outer diameter during tightening, thus clamping the wire spring. The right end of the clamping sleeve has a cylindrical pin hole (24) and a square pin hole (25) for fixing, such as... Figure 7 As shown.

[0060] The cylindrical pin (13) is mainly used to fix the wire spring fixing rod (11) in the clamping sleeve (12). It can be firmly positioned to prevent the wire spring fixing rod (11) from coming out.

[0061] The sliding component (14) has a central inner hole that mates with the clamping sleeve (12). Its left end has a taper to tighten the clamping sleeve (12). The sliding component is cylindrical in the middle and rectangular on both sides to fix its direction and mate with the rectangular hole of the fixed base (4), allowing it to slide back and forth. The right end of the sliding component has roller positions and shaft holes on both sides for mounting the round shaft (15) and roller (16), such as... Figure 8 and Figure 9 Enlarged illustration.

[0062] Two round shafts (15) are used, one on the left and one on the right. After the roller (16) is placed in the space of the slider (14), the round shafts (15) are inserted from both sides to fix the roller (16). The roller (16) can also rotate on the round shafts (15).

[0063] The roller (16) is fixed by the round shaft (15) after being placed in the corresponding position of the slider (14). After installation, the roller contacts the lower plane of the push block (17) and pushes the slider (14) forward by the push block (17).

[0064] The push block (17) has steps and ramps on the surface that contacts the roller (16). When the push block (17) moves downward, it will push the roller (16) to rotate and drive the sliding member (14) to slide to the left, thereby shrinking the clamping sleeve (12). A cylinder is connected above the push block (17), and the cylinder drives the push block (17) to move up and down. The right side is in contact with the stepped surface of the baffle (6), and spatial constraints can be obtained when it moves up and down.

[0065] After the square pin (18) and the clamping sleeve (12) are inserted into the baffle (6), the square pin (18) can be inserted to fix the clamping sleeve (12) in the baffle (6).

[0066] The return spring (19) has one end installed in the fixed seat (4), which has a spring fixing platform at the corresponding position, and the other end installed in the platform of the slider (14). Its main function is to reset the slider (14) by the spring force after the push block (17) rises.

[0067] The working process of this device is as follows: the cylinder (1) actuates, driving the push block (17) downward. The push block (17) pushes the roller (16) through its ramp and steps, causing the sliding part (14) to move to the left. The clamping sleeve (12) and its internal parts are fixed and cannot move. The left end of the clamping sleeve (12) contracts through the tapered contraction in the sliding part (14), converging towards the center. This causes the pressure teeth at the left end of the clamping sleeve (12) to press the spring wire (8) into the spring wire groove in the spring wire fixing rod (11), thus achieving the function of fixing 12 spring wires. Figure 10As shown. Release the cylinder (1), push the block (17) upward, leaving space for the sliding part (14) to retreat. At this time, the elastic force of the reset spring (19) causes the sliding part (14) to retreat and reset. After resetting, the tapered pressure teeth at the left end of the clamping sleeve (12) are released and reset without the contraction of the sliding part (14), and the wire spring can be released.

[0068] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
