Abstract
Description
Technical Field
[0001] This utility model relates to the field of pickup truck hood technology, specifically to a step roller vehicle. Background Technology
[0002] Roller sewing machines, used for sewing and embellishing leather, are primarily used for sewing high-end leather shoes, bags, straps, and curved belts. Stepper roller sewing machines, in particular, utilize stepper motors to drive the upper and lower rollers and needle for synchronous feeding, and can adjust the stitch length using a stitch length adjustment component.
[0003] Currently, the stepper motors in roller machines are usually either completely recessed inside the machine head or completely exposed outside the machine head, which results in extremely high requirements for the accuracy of the motor installation position and affects the overall installation efficiency. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stepping roller to solve the above-mentioned problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stepper roller carriage, including a machine head and a stepper motor, wherein the motor shaft of the stepper motor is connected to an external lifting foot mechanism, characterized in that: the machine head is provided with a mounting window, the stepper motor is vertically mounted on the mounting window, the motor shaft of the stepper motor is oriented toward the inside of the machine head, a mounting bracket is provided between the mounting window and the stepper motor, and the stepper motor is provided with a bearing end cap for cooperating with the mounting bracket;
[0006] The bearing end cover is located inside the machine head and has an extension section along the setting direction of the stepper motor. The extension section extends to the middle of the stepper motor, and the mounting bracket is connected to the extension section and located in the middle of the stepper motor; or, the bearing end cover has at least one connecting post, the connecting post extends to the middle of the stepper motor, and the mounting bracket is connected to the connecting post and located in the middle of the stepper motor.
[0007] Furthermore, the mounting bracket is provided with at least one first mounting hole, the extension section or connecting column is provided with at least one boss, the boss is provided with a second mounting hole, the mounting bracket is installed with the extension section or connecting column through the first mounting hole and the second mounting hole, and the mounting bracket is also provided with at least one third mounting hole.
[0008] Furthermore, the machine head is provided with at least one positioning hole, and the mounting bracket is positioned and installed through the positioning hole and the third mounting hole.
[0009] Furthermore, the bearing end cover and the mounting bracket are integrally formed, and the mounting bracket is located in the middle of the stepper motor.
[0010] The beneficial technical effects of this utility model are as follows: by cooperating with the mounting bracket, bearing end cover, and mounting window, the stepper motor and the machine head can be quickly installed and positioned without adjusting the installation position of the stepper motor. At the same time, by using the bearing end cover as an installation support point, the cut-out size of the overall motor housing is reduced, and by using the high-strength mounting bracket as a support, the overall installation stability is further improved.
