Description

Technical Field

[0001] This utility model relates to the field of refrigerator manufacturing technology, specifically to a precision forming device for refrigerator stator covers. Background Technology

[0002] In modern home appliance manufacturing, refrigerators, as important household appliances, enjoy consistently stable market demand. The refrigerator stator cover is a key component in the refrigerator motor system. As the power source of the refrigerator, the stable operation of the motor is crucial for its normal functioning. The stator cover plays multiple roles in the motor, including fixing the stator core, protecting the internal structure, and assisting in heat dissipation. It needs to fit tightly with the stator core to ensure that the motor does not loosen or vibrate during operation, thereby guaranteeing the motor's efficiency and stability.

[0003] During the molding process of the refrigerator stator cover, drilling is required. This involves precisely machining various mounting holes and ventilation holes on the stator cover to meet the needs of motor assembly and heat dissipation. Currently, in the manual drilling operation of refrigerator stator covers, operators first need to obtain the stator cover blank to be drilled from the production line. Then, the stator cover blank is placed on a simple drilling fixture. After placement, the operator uses a handheld electric drill or bench drill to drill holes in the stator cover according to the design drawings. During the drilling process, the operator needs to rely on their experience and feel to control the position, depth, and angle of the drill hole. At the same time, they also need to pay attention to the drilling speed and force to avoid problems such as drill bit breakage and stator cover deformation. However, due to the difficulty in guaranteeing the accuracy of manual drilling, the scrap rate of refrigerator stator covers is relatively high, resulting in a decline in product quality.

[0004] Therefore, in order to address the above problems, the applicant needs to design a precision forming device for refrigerator stator covers to solve the problem. Utility Model Content

[0005] The purpose of this invention is to provide a precision forming device for refrigerator stator covers to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision forming device for a refrigerator stator cover, comprising a base,

[0007] It also includes: a drilling mechanism disposed above the base, and the drilling mechanism is used to drill holes in the refrigerator stator cover. The drilling mechanism includes a support frame fixedly connected to the base, and a servo motor is fixedly disposed on the support frame. The output end of the servo motor is provided with a lead screw, and a moving part is threaded on the lead screw. A controller is fixedly disposed on the moving part, and a rotatable drill bit is disposed on the controller.

[0008] A control mechanism is provided above the base and is used to place the stator cover and transfer the stator cover to the bottom of the drill bit. The control mechanism includes a movable plate and a first linear module is fixedly provided above the movable plate. A first connector is slidably provided on the first linear module and a placement platform for placing the stator cover is fixedly provided above the first connector.

[0009] Furthermore, a second connector is fixedly disposed below the movable plate, and a second linear module is slidably disposed below the second connector, and the second linear module is fixedly connected to the base.

[0010] With the above structural design, when in use, the second linear module will start and drive the second connector to move. The movement of the second connector will facilitate the movement of the movable plate, thereby facilitating precise drilling on the stator cover.

[0011] Furthermore, a slider is fixedly installed below the movable plate, and a slide rail is slidably installed below the slider, with the slide rail being fixedly connected to the base.

[0012] The above structural design utilizes sliders and grooves to easily restrict the movement direction of the movable plate and improve the smoothness of its movement.

[0013] Furthermore, the inner side of the placement platform is provided with a sliding groove, and a sliding plate for clamping the stator cover is slidably disposed in the sliding groove.

[0014] Through the above structural design, the slide groove facilitates the sliding of the slider, and the sliding of the slider facilitates the clamping of the stator cover placed in the platform.

[0015] Furthermore, the slide plate is threaded with a threaded rod, and one end of the threaded rod is fixedly fitted with a pressing plate.

[0016] With the above structural design, when in use, the external force is used to rotate the threaded rod to facilitate the movement of the extrusion plate. The extrusion plate abuts against the placement platform to stabilize the slide plate, thereby firmly clamping the stator cover.

[0017] Furthermore, the support frame is provided with guide rods on both sides of the lead screw, and the guide rods are slidably connected to the moving part.

[0018] Through the above structural design, the guide rod facilitates the limiting of the moving part's direction of movement during use, preventing the moving part from deviating.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the refrigerator stator cover precision forming device facilitates precise drilling on the stator cover and has high safety, as detailed below:

[0020] When using this refrigerator stator cover precision forming device, the stator cover is placed in the placement platform, the sliding plate clamps the stator cover, and external force is used to rotate the threaded rod. The rotation of the threaded rod facilitates the descent of the extrusion plate, which in turn stabilizes the sliding plate, thus firmly clamping the stator cover. Once the stator cover is securely installed, the control mechanism moves the placement platform below the drill bit and starts the servo motor. The servo motor starts, which drives the lead screw to rotate. The rotation of the lead screw drives the moving parts to move, which in turn drives the controller to move. The controller then drives the drill bit to drill holes in the stator cover, facilitating precise drilling and improving the quality of the stator cover.

[0021] When using this refrigerator stator cover precision forming device, after the stator cover is securely installed, the first linear module and the second linear module are activated. The movement of the first linear module will drive the first connecting piece to move, and the movement of the first connecting piece will drive the placement platform to move. At the same time, the movement of the second linear module will drive the second connecting piece to move, and the movement of the second connecting piece will drive the movable plate to move. This facilitates the transfer of the placement platform to below the drill bit, making it convenient to place the stator cover at a distance and then transfer it to below the drill bit for precise drilling, ensuring high safety.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-4 As shown, this utility model discloses a precision forming device for a refrigerator stator cover, including a base 1 and a drilling mechanism 2 disposed above the base 1. The drilling mechanism 2 is used to drill holes in the refrigerator stator cover. The drilling mechanism 2 includes a support frame 20 fixedly connected to the base 1, and a servo motor 21 is fixedly disposed on the support frame 20. A lead screw 22 is disposed at the output end of the servo motor 21, and a moving part 23 is threaded on the lead screw 22. A controller 24 is fixedly disposed on the moving part 23, and a rotatable drill bit 25 is disposed on the controller 24. A slide groove 11 is disposed on the inner side of the placement platform 10, and a slide plate 12 for clamping the stator cover is slidably disposed in the slide groove 11. A threaded rod 13 is threaded on the slide plate 12, and a pressing plate 14 is fixedly disposed at one end of the threaded rod 13. Guide rods 26 are disposed on both sides of the lead screw 22 on the support frame 20, and the guide rods 26 are slidably connected to the moving part 23. The controller 24 is an existing control device used to drive the drill bit 25 to rotate.

[0029] With the above structural design, during use, after the stator cover is placed in the placement platform 10, the slide plate 12 clamps the stator cover, and the threaded rod 13 is rotated by external force. The rotation of the threaded rod 13 will facilitate the downward movement of the extrusion plate 14. The downward movement of the extrusion plate 14 will stabilize the slide plate 12, thereby firmly clamping the stator cover. After the stator cover is firmly installed, the control mechanism 3 is used to move the placement platform 10 to below the drill bit 25 and start the servo motor 21. The start of the servo motor 21 will drive the lead screw 22 to rotate. The rotation of the lead screw 22 will drive the moving part 23 to move. The movement of the moving part 23 will drive the controller 24 to move. The controller 24 will drive the drill bit 25 to drill a hole in the stator cover, which will facilitate precise drilling in the stator cover and improve the quality of the stator cover.

[0030] The control mechanism 3 is located above the base 1 and is used to place the stator cover and transfer it below the drill bit 25. The control mechanism 3 includes a movable plate 30, and a first linear module 31 is fixedly arranged above the movable plate 30. A first connector 32 is slidably arranged on the first linear module 31, and a placement platform 10 for placing the stator cover is fixedly arranged above the first connector 32. A second connector 35 is fixedly arranged below the movable plate 30, and a second linear module 36 is slidably arranged below the second connector 35 and is fixedly connected to the base 1. A slider 33 is fixedly arranged below the movable plate 30, and a slide rail 34 is slidably arranged below the slider 33 and is fixedly connected to the base 1.

[0031] With the above structural design, when the stator cover is securely installed, the first linear module 31 and the second linear module 36 are activated. The movement of the first linear module 31 will drive the first connecting piece 32 to move, and the movement of the first connecting piece 32 will drive the placement platform 10 to move. At the same time, the movement of the second linear module 36 will drive the second connecting piece 35 to move, and the movement of the second connecting piece 35 will drive the movable plate 30 to move. This facilitates the transfer of the placement platform 10 to below the drill bit 25, and makes it easier to accurately drill the stator cover after it has been placed at a distance. This ensures high safety.

[0032] Working principle: When using this refrigerator stator cover precision forming device, after placing the stator cover in the placement table 10, the slide plate 12 clamps the stator cover, and external force is used to rotate the threaded rod 13. The rotation of the threaded rod 13 facilitates the downward movement of the extrusion plate 14. The downward movement of the extrusion plate 14 stabilizes the slide plate 12, thereby firmly clamping the stator cover. After the stator cover is securely installed, the first linear module 31 and the second linear module 36 are activated. The movement of the first linear module 31 will drive the first connecting member 32 to move, and the movement of the first connecting member 32 will drive the placement table 10 to move. The movement of the second linear module 36 will simultaneously drive the second connector 35 to move, which in turn will drive the movable plate 30 to move. This will facilitate the transfer of the placement platform 10 to below the drill bit 25 and activate the servo motor 21. The activation of the servo motor 21 will drive the lead screw 22 to rotate, which will drive the moving part 23 to move. The movement of the moving part 23 will drive the controller 24 to move, which will drive the drill bit 25 to drill holes in the stator cover. This will facilitate precise drilling in the stator cover and improve the quality of the stator cover.
