Description

Technical Field

[0001] This utility model relates to the field of lead screw stepper motor technology, specifically an integrated lead screw stepper motor. Background Technology

[0002] In the fields of automation and precision machinery, lead screw stepper motors are widely used as drive devices in various positioning, transmission, and processing equipment. Their core advantage lies in their ability to directly convert electrical energy into precise linear or rotary motion, while possessing excellent control performance and high positional accuracy.

[0003] Existing lead screw stepper motors typically employ natural cooling or simple fan cooling methods. Under high-intensity, continuous operation, these cooling methods often fail to effectively dissipate the heat generated inside the motor in a timely manner, leading to increased motor temperature and consequently affecting its performance and lifespan. Furthermore, the design of existing lead screw stepper motors often lacks standardized interfaces and flexible assembly mechanisms, making their integration into more efficient external cooling structures complex and costly. This incompatibility not only increases the difficulty of system integration but also limits the flexibility for users to customize cooling solutions according to specific application scenarios. Utility Model Content

[0004] The purpose of this invention is to provide an integrated ball screw stepper motor to address the issues raised in the background section. Existing ball screw stepper motors typically employ natural cooling or simple fan cooling methods. These methods often fail to effectively dissipate heat generated inside the motor during high-intensity, continuous operation, leading to increased motor temperature and impacting performance and lifespan. Furthermore, existing ball screw stepper motor designs often lack standardized interfaces and flexible assembly mechanisms, making integration into more efficient external cooling structures complex and costly. This incompatibility not only increases the difficulty of system integration but also limits the flexibility of users in customizing cooling solutions for specific application scenarios.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated lead screw stepper motor, comprising a lead screw stepper motor body, a protective outer frame provided on the outer side of the lead screw stepper motor body, a connecting plate fixedly connected to one side of the protective outer frame, a front plate fixedly connected inside the connecting plate, a mounting groove provided in the center of the front plate, and a slot provided on one side of the front plate corresponding to the top and bottom of the mounting groove, one side of the lead screw stepper motor body extending into the interior of the protective outer frame, and a locking plate fixedly connected to one side of the top and bottom of the lead screw stepper motor body, the side of the locking plate away from the lead screw stepper motor body extending into the interior of the slot and engaging with the slot, a fixing bolt threadedly connected to one side of the locking plate, and one side of the fixing bolt extending into the interior of the front plate and threadedly connected to the front plate.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This integrated ball screw stepper motor utilizes heat-conducting metal plates fixedly connected to the top and bottom of the motor body, along with several heat-conducting rods extending from these plates. Heat is rapidly conducted to the heat sink and ultimately dissipated into the air through the heat dissipation fins on the heat sink. This design significantly improves heat transfer efficiency and effectively reduces the motor's operating temperature. The motor body quickly engages with the slot on the front plate via a locking plate and is further secured with bolts, achieving rapid and stable assembly of the motor body and the heat dissipation structure. This design simplifies the assembly process and reduces assembly costs. The locking design of the slot on the protective frame and the mounting plate, along with the cooperation of the positioning slot and positioning block, allows for modular installation and disassembly of the cooling fan and its auxiliary structures. This facilitates flexible adjustment of the cooling solution according to specific application scenarios and also facilitates subsequent maintenance and upgrades. Attached Figure Description

The heat dissipation plate 14 is threadedly connected to the heat-conducting metal plate 12 by bolts.

[0016] A rear plate 3 is fixedly installed on the other side of the protective outer frame 2 by bolts, and a heat dissipation mesh 4 is fixedly installed in the center of the rear plate 3.

[0017] Ventilation mesh 11 is fixedly installed at both the top and bottom positions of the connecting plate 5.

[0018] Mounting plates 18 are provided on both sides of the top and bottom of the protective frame 2. Slots 16 are provided on both sides of the top and bottom of the protective frame 2. The two mounting plates 18 are respectively inserted into the two slots 16 and engaged with them.

[0019] The two slots 16 are provided with positioning grooves 17 on both sides of the opposite end. The two mounting plates 18 are fixedly connected to positioning blocks 21 on both sides of the opposite side. The side of the positioning block 21 away from the mounting plate 18 extends into the positioning groove 17 and engages with the positioning groove 17. The mounting plates 18 are threaded with mounting bolts 22 on both sides. The bottom of the mounting bolts 22 passes through the mounting plate 18 and the positioning block 21 in sequence and is threadedly connected to the protective frame 2.

[0020] Two mounting plates 18, one above the other, are fixedly mounted with cooling fans 19 on opposite sides. The input end of the cooling fan 19 is connected to a heat absorption pipe 20, and the side of the heat absorption pipe 20 away from the cooling fan 19 extends into the interior of the protective frame 2.

[0021] Working principle: Using appropriate tools, first remove the bolts on the rear plate 3 and remove the rear plate 3 from the protective frame 2. This step allows for the subsequent disassembly of the heat dissipation components from the rear of the motor. After removing the rear plate 3, disconnect the mounting plate 18 from the protective frame 2 via the mounting bolts 22. The mounting plate 18 is engaged with the protective frame 2 via the slot 16 and the positioning slot 17. When disassembling, loosen the mounting bolts 22 first, and then gently pull out the mounting plate 18.

Use tools to loosen these bolts and remove the heat dissipation plate 14 and its heat dissipation fins 15 from the heat-conducting metal plate 12.

Finally, the lead screw stepper motor body 1 is engaged with the slot 8 on the front plate 6 via the first slot 9 and further secured by the fixing bolts 10. Use a screwdriver to disconnect these fixing bolts 10. After disconnecting all the fixed connections, gently remove the lead screw stepper motor body 1 from the protective frame 2.

This design greatly improves heat conduction efficiency and effectively reduces the temperature of the motor during operation. The lead screw stepper motor body 1 is quickly engaged with the slot 8 on the front plate 6 via the clamping plate 9, and further secured by the fixing bolts 10, achieving rapid and stable assembly of the motor body and the heat dissipation structure. This design simplifies the assembly process and reduces assembly costs. The engagement design of the slot 16 on the protective frame 2 with the mounting plate 18, and the cooperation between the positioning slot 17 and the positioning block 21, allow the cooling fan 19 and its auxiliary structures to be modularly installed or disassembled, facilitating users to flexibly adjust the heat dissipation scheme according to specific application scenarios, and also facilitating subsequent maintenance and upgrades.
