[0002] In order to connect the motor, terminals are often used. Terminals are a kind of accessory product used to achieve electrical connection, which is classified as connectors in the industry. With the development of the electronics industry, the scope of use of terminals is increasing, and there are more and more types. In addition to PCB terminals, the most widely used ones are hardware terminals, nut terminals, spring terminals, etc. The terminals are crimped when connected to the wires.

[0003] The crimping equipment in the prior art is shown in the Chinese patent with application number 202122562978.5, which discloses a quick crimping tool for motor terminals, including: a base and a quick crimping mechanism arranged on the base; the quick crimping mechanism includes a pair of vertical support rods arranged on the base, an upper pressing plate arranged on the vertical support rods and a lower supporting plate arranged on the base, the lower supporting plate is provided with a lower work station plate, and the lower work station plate is provided with a plurality of lower crimping work station grooves, the lower end of the upper pressing plate is provided with an upper work station plate, and the upper work station plate is provided with an upper crimping work station groove opposite to the lower crimping work station groove, the upper end of the upper work station plate is provided with a pushing rod passing through the upper pressing plate, and the upper end of the pushing rod is provided with a driving member; the base is also provided with a supporting component for supporting the terminal.

[0004] Although this equipment can improve the processing efficiency of terminal crimping, it still has the following shortcomings when used: due to the existence of terminals of different specifications and sizes during the production process, the distance between the support component and the quick crimping mechanism is not easy to adjust: when producing smaller motor terminals, the quick crimping mechanism will not be able to contact the motor terminals enough and cannot be pressed; when producing larger motor terminals, the quick crimping mechanism will contact the motor terminals too much and squeeze the terminals out of shape, which makes the quality of the produced motor terminals unable to be guaranteed.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0023] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood by specific circumstances.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1A DC motor terminal press-fitting processing device includes a top frame 2 and a base 1. Both the top frame 2 and the base 1 adopt an n-type structure, and the top frame 2 is fixedly mounted above the base 1. The inner top of the top frame 2 is connected with a driving member 3. The lower end of the driving member 3 is installed with an upper die 4. The driving member 3 can be, but is not limited to, an electric push rod to drive the upper die 4 to extend and retract. A lower die 5 is supported by a supporting plate 6 above the base 1, and the lower die 5 is aligned with the upper die 4 up and down, so that the upper die 4 can press the lower die 5 to press the motor terminal. In order to facilitate the different specifications of the motor terminals, The terminals are crimped, and the support plate 6 is connected to the base 1 through a screw 7 and a screw sleeve 8. The screw 7 cooperates with the screw sleeve 8 to control the support plate 6 to approach or move away from the base 1, so as to adjust the initial distance between the lower die 5 and the upper die 4, wherein the outer side of the screw sleeve 8 is rotatably connected to the base 1, and the screw 7 passes through the inside of the screw sleeve 8, the screw 7 is threadedly connected to the screw sleeve 8, and the top of the screw 7 is fixed to the bottom of the support plate 6, so that when the screw sleeve 8 is rotated, the threaded action between the screw 7 and the screw sleeve 8 can be used to drive the support plate 6 to move up and down relative to the base 1 through the screw 7.

[0026] See also Figure 1-2 In order to improve the stability of the screw 7 and the screw sleeve 8 during adjustment, four groups of screws 7 and screw sleeves 8 are provided, and the four groups of screws 7 and screw sleeves 8 are respectively arranged at the four corners of the support plate 6. The screws 7 and screw sleeves 8 can not only synchronously support the support plate 6 at the four corners, but also different groups of screws 7 and screw sleeves 8 can also play a certain limiting role, thereby preventing the screw 7 and the support plate 6 from rotating.

[0027] See also Figure 2 In order to ensure the flatness of the four sides when the support plate 6 is lifted or lowered, it is necessary to control the adjustment amounts of the four sets of screw rods 7 and screw sleeves 8 to be consistent. Therefore, the outer walls of the four screw sleeves 8 are fixed with gear rings 9, and the middle positions of the four gear rings 9 are synchronously meshed with a center gear 10. The center gear 10 is rotatably connected to the base 1. By rotating the center gear 10, the four screw sleeves 8 can be synchronously driven to rotate by the meshing action with the gear ring 9, thereby ensuring the consistency of the rotation adjustment. At the same time, the adjustment operation steps can be simplified, and it is more convenient to use. In order to facilitate the control of the rotation of the center gear 10, a shaft of the center gear 10 is extended out of the bottom end of the base 1 and is connected with a handle 11. The handle 11 has a petal-shaped structure, which is convenient for the user to hold.

[0028] See also Figure 4 In order to facilitate the control of the accuracy of the adjustment of the support plate 6, a pointer 13 is connected to the side of the support plate 6, and a scale line 12 matching the pointer 13 is provided on the inner wall of the side plate of the top frame 2. The pointer 13 is close to the scale line 12, so that the operator can timely understand the changes in the adjustment amount when the support plate 6 is raised or lowered.

[0029] See also Figure 1The lower surface of the upper die 4 is provided with a plurality of pressing blocks 41, and the upper surface of the lower die 5 is provided with a plurality of limiting grooves 51 corresponding to the pressing blocks 41. The limiting grooves 51 can limit the motor terminals so that they are stuck inside the limiting grooves 51, which is convenient for the pressing blocks 41 to be crimped. At the same time, the number of the pressing blocks 41 and the limiting grooves 51 is not less than three, so that multiple motor terminals can be crimped at one time, which is beneficial to improve the processing efficiency of the crimping operation.
