Description

Technical Field

[0001] The present application relates to the field of motors, and in particular, to an integrated plunger pump motor. Background Art

[0002] A stepper motor is an electric motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. The casing of a traditional stepper motor generally does not have fins for heat dissipation. When the load is too large or the running speed is too high, the heat generated by the stepper motor cannot be dissipated in time, which may cause the stepper motor to overheat, thereby affecting its performance. Long-term overheating may cause damage to the stepper motor. Summary of the invention

[0003] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0004] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide an integrated plunger pump motor, including two symmetrically arranged fasteners, which are detachably fixed to the outer periphery of the stepper motor, and the two fasteners are respectively arranged at both ends of the stepper motor, and a heat conducting plate is fixed between the two fasteners, and a plurality of equidistantly distributed fins are fixed on a side of the heat conducting plate away from the stepper motor, and the heat conducting plate is abutted against the outer periphery of the stepper motor.

[0005] Through the above technical solution, two fasteners fasten the heat conducting plate to the surface of the stepper motor, so that the heat conducting plate abuts against the surface of the stepper motor. The heat generated by the stepper motor during operation is transferred to the heat conducting plate through its outer casing, and the setting of the fins increases the heat dissipation on the heat conducting plate, thereby increasing the heat dissipation effect of the stepper motor.

[0006] Furthermore, the fastener consists of a vertically arranged pressure plate and two horizontally arranged buckle plates, the two buckle plates are fixed at both ends of the pressure plate and are perpendicular to the pressure plate, the pressure plate abuts against the outer periphery of the stepper motor, and the two buckle plates are buckled on the outer periphery of the stepper motor.

[0007] Through the above technical solution, the setting of the buckle plate can increase the connection strength between the fastener and the stepper motor.

[0008] Furthermore, a connecting plate is fixedly provided on the buckle plate on the side close to the output shaft of the stepper motor, and a through hole is opened in the connecting plate and penetrates along the thickness thereof, and the through hole corresponds to the mounting hole on the front end cover of the stepper motor, and the connecting plate is fixed to the stepper motor by bolts passing through the through hole and the mounting hole.

[0009] Through the above technical solution, the fastener can be firmly fixed on the stepper motor, thereby ensuring the firmness of the connection between the fin and the stepper motor.

[0010] Furthermore, two sleeves are fixedly provided on one side of the pressure plate away from the stepper motor, a connecting rod is fixed in the sleeve on one of the pressure plates, the connecting rod passes through the sleeve on the other pressure plate, a positioning ring abutting against the sleeve is fixed on the outer periphery of the connecting rod, one end of the connecting rod fixed with the positioning ring is internally threadedly connected with a screw, and the screw cooperates with the positioning ring to clamp the sleeve.

[0011] Through the above technical solution, the pressure plate on the side away from the front end cover of the stepper motor is detachably connected to the connecting rod, and the provision of the connecting rod also increases the connection strength between the two pressure plates.

[0012] Furthermore, a groove is provided on an end surface of one side of the pressure plate close to the stepping motor, and two ends of the heat conducting plate along the axis of the stepping motor are embedded in the groove.

[0013] The above technical solution makes it easy to disassemble and assemble the heat conducting plate from between the two pressing plates, so as to facilitate the replacement of the heat conducting plate and the fins.

[0014] Furthermore, a guide groove is provided on an end surface of the pressure plate away from the stepper motor, and a bottom wall of the guide groove gradually inclines toward a side away from the stepper motor from a side close to the fin to a side away from the fin.

[0015] Through the above technical solution, the provision of the guide groove can guide the airflow to the bottom of the fin, thereby increasing the heat dissipation effect of the fin.

[0016] The beneficial effect of the present application is that an integrated plunger pump motor with efficient heat dissipation is provided. BRIEF DESCRIPTION OF THE DRAWINGS

A heat conducting plate 31 is fixed between the two fasteners, and a plurality of equidistantly distributed fins 30 are fixed to a side of the heat conducting plate 31 away from the stepper motor. The heat conducting plate 31 abuts against the outer periphery of the stepper motor, and the heat conducting plate 31 and the fins 30 are both made of copper.

[0033] Reference Figure 2 , Figure 3 The fastener is composed of a vertically arranged pressure plate 13 and two horizontally arranged buckle plates 10.

The pressure plate 13 abuts against the outer periphery of the stepper motor, and the two buckle plates 10 are buckled on the outer periphery of the stepper motor.

[0034] Reference Figure 2 , Figure 3 A connecting plate 12 is fixedly provided on the side buckle plate 10 close to the output shaft of the stepper motor. A through hole is opened in the connecting plate 12 and penetrates along its thickness. The through hole corresponds to the mounting hole on the front end cover of the stepper motor. The connecting plate 12 is fixed to the stepper motor by bolts passing through the through hole and the mounting hole.
