Description

Technical Field

[0001] The utility model belongs to the technical field of motor harness production equipment, and in particular relates to a motor wire terminal stamping assembly. Background Art

[0002] During the processing of motor wire assemblies, in order to meet the requirements of automated processing of electronic products, terminals are often punched at the tail ends of the wires. During the stamping process of the terminals and the ends of the wires, in order to stamp the terminals and the ends of the wires more tightly, the upper and lower stamping strokes of the stamping die are set to be larger, so that the die has greater force when connecting the terminals and the ends of the wires. However, the increased stroke structure will increase the downward distance between the ends of the wire harness and the terminals during the stamping process, resulting in a change in the relative position of the two, which affects the quality of the connection.

[0012] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0013] Embodiment: A motor terminal stamping assembly, such as Figure 1-Figure 3 As shown, it includes a carrying platform 1, and two pressing plates 2 are symmetrically provided on the upper surface of the carrying platform 1. The lower surfaces of the two pressing plates 2 near one end are provided with a giving way groove 3. The front end of the carrying platform 1 is provided with a punching platform 4, and the punching platform 4 is fixedly connected to the carrying platform 1. The punching platform 4 includes two longitudinal grooves 5 provided inside, and the rear end surfaces of the two longitudinal grooves 5 are flush with the front end surface of the carrying platform 1. A lifting platform 6 is provided in the punching platform 4, and the lifting platform 6 is slidably connected in the punching platform 4 through the longitudinal groove 5. The bottom of the punching platform 4 is provided with a bottom Plate 7, a boss 8 is provided on the bottom plate 7, the boss 8 extends to between the two longitudinal slide grooves 5 in the stamping table 4, the upper surface of the boss 8 is provided with two lower mounting holes 9, and the two lower mounting holes 9 are provided with springs 10. The lower surface of the lifting platform 6 is provided with upper mounting holes 11 corresponding to the lower mounting holes 9, and the tops of the two springs 10 are fixedly connected to the upper mounting holes 11 in the lifting platform 6. The upper surface of the lifting platform 6 is flush with the upper surface of the bearing platform 1, and the top of the longitudinal slide groove 5 is provided with a limit block 12 for limiting the position of the lifting platform 6.

[0014] A forming die 13 is provided above the lifting platform 6 , and a semicircular arc forming cavity 14 is provided on the lower surface of the front end of the forming die 13 .

[0015] The rear end surface of the forming die 13 and the rear end surface of the lifting platform 6 are arranged flush with each other.

[0016] The principle of the present utility model is as follows: when in use, the continuous terminal row is restricted by the two pressing plates 2 and slides forward on the supporting platform 1. The terminal at the front end will be placed on the lifting platform 6, and the stripped wire will be placed on the terminal at the front end. The forming mold 13 is driven downward by a cylinder or a motor. During this period, the lifting platform 6 will press the terminal and the wire between the forming mold 13 and the lifting platform 6 due to the force of the spring 10 to avoid displacement. When the lifting platform 6 is pressed on the boss 8 of the bottom plate 7, the forming mold 13 continues to move downward to bend the terminal through the forming mold 13 to connect the terminal and the wire. The rear end face of the forming mold 13 is flush with the rear end face of the lifting platform 6. In the process of moving downward, the terminal at the front end is punched off from the terminal row.
