[0020] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will describe in detail the specific embodiments of the present utility model with reference to the drawings. Examples of these preferred embodiments are illustrated in the drawings. The embodiments of the present utility model shown in the drawings and described according to the drawings are merely exemplary, and the present utility model is not limited to these embodiments.

[0021] Here, it should also be noted that in order to avoid obscuring the present utility model with unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, while other details less related to the present utility model are omitted.

[0022] Also, in the description of the present utility model, the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model 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. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0023] The DD motor, whose full name is Direct Drive Motor and is abbreviated as DD, is a direct drive motor. It does not need to decelerate or transmit power through any mechanical transmission devices (such as ball screws, gears, belts, etc.), but directly converts the rotational motion of the motor into the linear or rotational motion required by the working device. Due to its characteristics such as high efficiency, high torque, and precise control, this kind of motor is widely used in various fields. However, the existing ones cannot meet the production efficiency and the rapid response for switching machine types, so it is necessary to develop a DD motor mechanism that can handle all sizes of types and improve the cutting efficiency.

[0024] Please refer to Figures 1-4 , the embodiments of the present utility model:

[0025] A load enhancement mechanism includes a ram fixing plate 1, a rotor 2, and a stator housing 3. The ram fixing plate 1 is fixedly connected to the rotor 2, the stator housing 3 is placed outside the rotor 2, and an enhancement device 4 is installed between the stator housing 3, the rotor 2, and the ram fixing plate 1.

[0026] The enhancement device 4 includes a transmission member 41 and a fastening member 42. The transmission member 41 is installed between the rotor 2 and the ram fixing plate 1, and the fastening member 42 holds both the stator housing 3 and the transmission member 41 at the same time. Due to the fastening member 42 of the present application holding both the stator housing and the transmission member at the same time, the rigidity of the DD motor is strengthened, and at the same time, the load of the DD motor is increased.

[0027] The transmission member 41 is a bearing. More specifically, the bearing selected is a rolling bearing. Since the rolling bearing is placed between the stator and the ram fixing plate, the stator is placed on the rolling bearing, achieving the effect of increasing the load.

[0028] The maximum diameter of the outer ring of the bearing is greater than the diameter of the rotor. In the specific implementation of the present application, since the maximum diameter of the outer ring of the bearing is greater than the rotor diameter, when the fastening member holds the stator housing and the outer ring of the bearing, it will not hold the rotor and does not affect the rotation of the rotor.

[0029] The upper end surface of the indenter fixing plate 1 is provided with a stepped mounting portion 11, and the transmission member 41 is mounted on the stepped mounting portion 11. In the specific implementation of the present application, a bearing is mounted on the stepped mounting portion. The side wall of the inner ring of the bearing abuts against the stepped mounting portion, and the outer side wall of the outer ring of the bearing is fixed by a fastener, which can relatively fixedly connect the indenter fixing plate and the stator housing, and at the same time enable the rotor to rotate. Without changing the crimping structure, it can cope with more product sizes and types, reduce the fluctuation of the crimping success rate and the response range of the crimping scheme, achieve the function of quickly switching machines and resuming machines, reduce the technical threshold of the equipment for personnel, and also improve the market competitiveness of the automatic crimping equipment.

[0030] The stator housing 3 and the rotor 2 are connected by a limiting device. When assembling the stator housing and the rotor, it is convenient and fast.

[0031] The limiting device includes a limiting recess 21 provided at the upper end of the mover 2 and a corresponding limiting protrusion 31 provided at the lower end of the stator housing 3. The limiting protrusion 31 is embedded in the limiting recess 21. The above limiting structure is only one of the embodiments of the present application, and any structure that enables the power and the stator housing to have a limiting and positioning structure during installation is within the protection scope of the present application.

[0032] The fastener 42 is a clamping hoop. The clamping hoop simultaneously locks and fixes the outer ring of the rolling bearing and the stator housing, that is, locks and fixes the stator housing and the indenter fixing plate. On the premise of adding a rolling bearing, it ensures the normal operation of the DD motor, and also strengthens the rigidity and improves the load. The clamping hoop 42 includes a hoop body and a fixing pin. The hoop body is annular with an opening. Upper and lower fixing parts are respectively provided at both ends of the opening, and the corresponding fixing parts at both ends of the opening are fixedly connected by the fixing pin.

[0033] A bearing platform 5 is provided at the upper end of the stator housing. In the specific implementation of the present application, the bearing platform is used to fix the stator of the DD motor, and other components such as hard limits, position sensors, light-shielding sheets, and indenters are installed on the bearing platform.

[0034] A motor includes a load enhancing mechanism as described in any one of the above.

[0035] In addition, it should be noted that in this specification, "including", "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.
