[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] See also Figure 1-17 The utility model provides a technical solution: a crimping device, comprising an A-pillar 1 and a transverse column 1 5 and a transverse column 2 8 respectively fixed to both ends of the A-pillar 1 by bolts;

[0043] B-pillar 2, horizontal column 1 5 is fixed between horizontal column 1 5 and horizontal column 2 8, and flange seat 4 is slidably connected between horizontal column 1 5 and horizontal column 2 8 via a slide rail;

[0044] Connecting rod 3, connecting rod 3 is hinged to B-pillar 2 through pins. There are two sets of connecting rods 3, which are symmetrically arranged. Sliding pins are fixed on both sides of one end of connecting rod 3. Sliding grooves that are compatible with the sliding pins are opened on the surface of flange seat 4. The sliding pins on connecting rod 3 can slide in the sliding grooves opened in flange seat 4.

[0045] The fixing plate 9 is arranged on one side of the flange seat 4, and the two ends of the fixing plate 9 are fixedly connected to the horizontal column 1 5 and the horizontal column 2 8 respectively;

[0046] The gearbox 19 is mounted on one side of the fixing plate 9 by bolts. A motor 13 is mounted on one side of the gearbox 19. A screw rod 6 is mounted on the output end of the gearbox 19. A spacer 12 is sleeved on the surface of the screw rod 6. The spacer 12 is connected to the gearbox 19. The flange seat 4 is threadedly connected to the screw rod 6.

[0047] The crimping sensor 10 is fixed to the surface of the flange seat 4 by bolts and is used to detect whether the crimping position is correct;

[0048] Photoelectric switch 20, the photoelectric switch 20 is arranged on the horizontal column 8 and corresponds to the pressure-connecting sensor piece 10;

[0049] A symmetrically arranged upper pressure block 16 is slidably connected between the A-pillar 1 and the B-pillar 2. An elliptical hole is provided at one end of the connecting rod 3. A slidable fixing pin is provided in the elliptical hole. One end of the fixing pin is fixedly connected to the upper pressure block 16. A tool 14 and a tool 2 15 are fixed to the sides of the upper and lower sets of upper pressure blocks 16 that are close to each other.

[0050] A finger cylinder 17 is provided on the horizontal column 15, and the clamping ends of the finger cylinder 17 are respectively fixed with a wire clamp arm A22 and a wire clamp arm B23, and the sides where the wire clamp arm A22 and the wire clamp arm B23 are close to each other are fixed with corresponding wire clamp bodies 24.

[0051] Preferably, a sensor pad 11 is fixed to the bottom of the photoelectric switch 20 by bolts, and the sensor pad 11 is fixedly installed on the surface of the horizontal column 28. The sensor pad 11 is used to adjust the distance between the photoelectric switch 20 and the crimped sensing piece 10, and can ensure that the photoelectric switch 20 is located directly above the sensor pad 11 and the distance remains constant. In order to ensure that the photoelectric switch 20 can accurately and stably detect the existence or passage of the crimped sensing piece 10, thereby improving the detection accuracy, because the working principle of the photoelectric switch 20 relies on the obstruction or reflection of the light beam, any change in distance may affect the detection result.

[0052] Preferably, the input end of the gearbox 19 is connected to the output end of the motor 13, and the gearbox 19 is driven by the rotation of the motor 13 to achieve precise control of the screw rod 6. Through the combination of the motor 13 and the gearbox 19, the position of the screw rod 6 can be precisely controlled. The gearbox 19 can provide different transmission ratios, so that a certain rotation angle of the motor 13 can correspond to a very small displacement of the screw rod 6, thereby achieving high-precision positioning.

[0053] Preferably, a limiting pressure plate 7 is fixed on the surface of the flange seat 4 close to one side of the sliding groove. The limiting pressure plate 7 limits the maximum and minimum positions of the sliding pin in the sliding groove by physical obstruction, preventing the connecting rod 3 from excessive extension or contraction, which helps to maintain the stability of the entire mechanical system.

[0054] Preferably, a nut washer 21 is provided on the surface of the fixing pin, which can prevent the fixing pin from detaching from the connecting rod 3 and reduce the direct friction between the fixing pin and the inner wall of the elliptical hole of the connecting rod 3, thereby reducing wear and extending the service life of the parts.

[0055] Preferably, a cylinder mounting plate 25 is fixedly installed on the surface of the horizontal column 5 near the finger cylinder 17 by bolts, and the finger cylinder 17 is fixedly installed on the surface of the cylinder mounting plate 25 by bolts, and the cylinder mounting plate 25 is used to stably fix the finger cylinder 17.

[0056] Preferably, a V-shaped groove is provided on the side where the two groups of wire clamp bodies 24 are close to each other, and the two groups of wire clamp bodies 24 are provided with mutually offset cuts, so that the two groups of wire clamp bodies 24 can be closed to each other. Since the wire clamp bodies 24 are provided with V-shaped grooves, they can provide better clamping stability, protect the wire surface from damage, and adapt to wires of different diameters.

[0057] Preferably, crimping stop sheet metal 18 is provided on both sides of the upper pressing block 16 located below, and one side of the crimping stop sheet metal 18 is fixedly connected to the horizontal column 2 8 to ensure the accuracy and stability of the wire during processing, and at the same time prevent the wire from being offset or falling during processing or movement.

[0058] During operation, the motor 13 is connected to an external power source for power supply. The operation of the motor 13 drives the gearbox 19 to operate, and the gearbox 19 drives the screw rod 6 to rotate. Since the screw rod 6 is threadedly connected to the flange seat 4, the flange seat 4 is driven to move. During this process, the sliding pin on the connecting rod 3 can slide in the sliding groove opened in the flange seat 4. At the same time, the connecting rod 3 is hinged to the B-pillar 2 through the pin, and then the upper pressure block 16 is driven to move along the A-pillar 1 and the B-pillar 2 through the two groups of connecting rods 3. The tool 1 14 and the tool 2 15 on the upper pressure block 16 are then close to prepare for the crimping operation. By using the transmission of the motor 13, it is more stable and efficient than the pneumatic device. The crimping parameters can be set, the wire types that can be processed are more extensive, the crimping stroke is large, and the space occupied by the ordinary terminal machine is small.

[0059] During the crimping process, the crimping sensor 10 detects whether the crimping position is correct. If there is a deviation in the position, the photoelectric switch 20 will send a signal to adjust the operation of the motor 13 through the control system, thereby correcting the position of the flange seat 4 to ensure the accuracy of the crimping.

[0060] At the same time, the finger cylinder 17 drives the wire clamp arm A22 and the wire clamp arm B23 to clamp the wire in preparation for crimping. When the tool 14 and the tool 2 15 reach the predetermined position, the crimping of the wire object is completed. Then, the motor 13 reverses and drives each component back to the initial position, waiting for the next operation instruction. When the device receives the start signal, through the crimping device set, for the sheathing and terminal crimping process of the sheathed wire, there is no need to first use the computer stripping machine to strip the outer skin of the sheathed wire, and then use the pneumatic stripping machine to strip the core wire. The outer skin and core wire of the sheathed wire can be stripped at one time. Before changing, the sheathed wire is stripped with a computer stripping machine first, and then the pneumatic stripping machine is replaced to strip the core wire, which improves efficiency, saves costs and is convenient to operate.

[0061] It should be noted that the tool 14 and the tool 2 15 are detachably mounted on the upper pressing block 16 and can be replaced with tool 14 and tool 2 15 of corresponding specifications according to the different types of wires to be processed, which is convenient, fast and easy to operate.

[0062] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
