Description

Technical Field

[0001] This utility model relates to the field of crimping machine technology, specifically a servo terminal crimping machine. Background Technology

[0002] Servo terminal crimping machines are processing equipment that quickly and accurately crimps wires to terminals or connectors, ensuring the reliability and safety of circuit connections. The main components include a drive system, a pressure and displacement control system, and a crimping die. During use, the drive system drives the moving die and the fixed die in the crimping die to move in opposite directions, thereby achieving quick and accurate crimping of wires to terminals or connectors.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5A servo terminal crimping machine includes a crimping machine body 1, a crimping mold 2 installed on the top of the crimping machine body 1, the crimping mold 2 including a moving mold and a fixed mold, and a crimping space provided between the moving mold and the fixed mold, an auxiliary support 3 provided at the front end of the crimping space, a holding mechanism and a supporting mechanism provided inside the auxiliary support 3, and a straightening and positioning space provided between the holding mechanism and the supporting mechanism, a baffle 20 for the front end of the crimping mold 2 is installed on one side of the top of the crimping machine body 1 to prevent the material inside the crimping mold 2 from flying and impacting, and a positioning plate is provided outside the rear end of the crimping space inside the crimping mold 2 to facilitate the installation of the subsequent assembly of wires and terminals before crimping;

[0025] The pressing mechanism includes two drive shafts 4, two L-shaped pressure plates 5, and two gears 6. The two L-shaped pressure plates 5 are respectively mounted on the surfaces of the two drive shafts 4, and the ends of the drive shafts 4 are mounted on the top structure of the auxiliary bracket 3 through bearings. The two gears 6 mesh with each other and are then connected to the front ends of the two drive shafts 4 respectively. One of the gears 6 is connected to a motor component.

[0026] The motor components include a reducer 7 and a motor 8. The output end of the motor 8 is connected to the input end of the reducer 7, and the output end of the reducer 7 is connected to the middle of the corresponding gear 6. Support seats are installed between the housing surface of the reducer 7, the housing surface of the motor 8, and the front end of the auxiliary bracket 3, thereby ensuring the stability of the continuous transmission operation of the reducer 7 and the motor 8.

[0027] After the motor component transmits power through the combination of two gears 6 and two drive shafts 4, it can make the two L-shaped pressure plates 5 rotate to be close together or rotate to be adjacent. The support mechanism includes a frame plate 9 and a T-shaped frame 10 fixed inside the auxiliary bracket 3. The top surface of the T-shaped frame 10 is set as an arc structure to increase the contact support area with the wire. The front and rear ends of the top of the T-shaped frame 10 are fixed with guide rods 12 that are engaged with the frame plate 9. The engagement effect between the guide rods 12 and the frame plate 9 can further improve the stability of the reciprocating lifting and lowering of the T-shaped frame 10 and the balanced top pressure effect of the T-shaped frame 10. The top of the T-shaped frame 10 is movably sleeved between the two L-shaped pressure plates 5, and the bottom of the T-shaped frame 10 is engaged through the frame plate 9 and a spring 11 is installed between the bottom of the frame plate 9 and the frame plate 9.

[0028] In use, the assembly of the wire and terminal is placed on the top surface of the T-shaped frame 10. Then, the assembly is pushed until the end of the assembly to be crimped fits into the crimping space and contacts the front surface of the positioning plate. Then, the motor 8 is started. The motor 8 drives two gears 6 through the reducer 7 to mesh relative to each other. The two gears 6 then drive two L-shaped pressure plates 5 to rotate and move in a 90-degree manner through their respective corresponding drive shafts 4. During the rotation of the two L-shaped pressure plates 5, they will gradually contact the assembly and press the assembly towards the top of the T-shaped frame 10. Under the elastic traction of the spring 11, the T-shaped frame 10 will descend a certain distance to make room, thereby adjusting the wire to a straight and stable state, creating favorable conditions for subsequent high-quality crimping operations.

[0029] After the assembly is clamped and stabilized, the existing drive system inside the crimping machine body 1 is started, which drives the moving mold and the fixed mold in the crimping mold 2 to automatically press together, thereby completing the fast and accurate crimping of the wire and terminal. After that, the motor 8 is restarted and its output is reversed. The motor 8 drives the two gears 6 through the reducer 7 to mesh with each other. The two gears 6 then drive the two L-shaped pressure plates 5 through their respective corresponding drive shafts 4 to reset and flip. The assembled wire and terminal after crimping is then removed.

[0030] Please see Figures 1-6 An auxiliary mechanism for adjusting the pressure of the T-shaped frame 10 is provided on the inner side of the bottom of the auxiliary support 3. The auxiliary mechanism includes an inclined top block 13 and an electric push rod 14. The bottom of the inclined top block 13 is engaged with a slide rail 15 fixed on the inner wall of the bottom of the auxiliary support 3. The output end of the electric push rod 14 is connected to the front end of the inclined top block 13. Under the transmission of the electric push rod 14, the inclined top block 13 can push the bottom of the T-shaped frame 10 upward or move away. The bottom surface of the T-shaped frame 10 is fixed with a hemispherical block that can fit and contact the inclined top surface of the inclined top block 13 to facilitate subsequent pressure transmission.

[0031] When in use, considering the small diameter of the wire, if the wire is still in a movable state after the two L-shaped pressure plates 5 flip over and cover the top of the T-shaped frame 10, the electric push rod 14 is activated. The output end of the electric push rod 14 drives the inclined top block 13, and then the inclined surface of the inclined top block 13 actively presses the T-shaped frame 10, so that the T-shaped frame 10 drives the wire to press and straighten the wire against the inner wall of the top of the two L-shaped pressure plates 5 in the merged state. This can also meet the production needs of subsequent crimping processing.

[0032] Please see Figure 6The inclined top block 13 has a slot and a semi-open slide 16 inside, and the slot and the semi-open slide 16 are connected. A transition plate 17 is engaged in the slot. One end of the transition plate 17 is connected to the output end of the electric push rod 14, and the other end of the transition plate 17 is fixed with a threaded rod 18 that engages with the semi-open slide 16. A nut 19 is threadedly connected to one end of the threaded rod 18 and can fit against and press against one side of the inclined top block 13.

[0033] In use, considering the pressure transmission range of the inclined top block 13 on the T-shaped frame 10, a solution is achieved using a threaded rod 18, nut 19, and other structures, as detailed below:

[0034] The transmission distance adjustment of the inclined top block 13 is based on the maximum stroke of the electric push rod 14. That is, the transition plate 17 is used as a transition support, and the semi-open slide groove 16 provides clearance space. The inclined top block 13 is moved to a suitable position under the triple guidance of the engagement between the threaded rod 18 and the semi-open slide groove 16, the engagement between the inclined top block 13 itself and the slide rail 15, and the engagement between the transition plate 17 and the groove. Then, the nut 19 is turned until the nut 19 fits against the outer surface of the inclined top block 13, thereby limiting the displacement of the inclined top block 13.

[0035] Please see Figures 1-3 The auxiliary bracket 3 has strip grooves on both sides of its bottom. The inner wall of the middle part of the crimping machine body 1 has screw holes aligned with the strip grooves. The auxiliary bracket 3 and the crimping machine body 1 can be detachably installed by using screws and strip grooves to connect to the screw holes.

[0036] In use, considering the maintenance of the entire device in the future, the auxiliary bracket 3 and the structure associated with the auxiliary bracket 3 can be modularly replaced by simply removing the screws between the bottom of the auxiliary bracket 3 and the middle of the crimping machine body 1.
