Description

Technical Field

[0001] This utility model belongs to the field of surface treatment technology for refrigerator beams, and more specifically, it relates to a device for strengthening the surface of refrigerator beams. Background Technology

[0002] As the refrigerator industry continues to develop, consumers' demands for lightweight and high-strength refrigerators are increasing. High-strength, lightweight refrigerator beams, with their advantage of balancing structural stability and overall weight reduction, are gradually becoming mainstream components. Common materials include aluminum alloys and composite lightweight alloys. To further balance high strength and lightweight characteristics, refrigerator beams typically require surface strengthening treatment. This involves spraying a strengthening layer onto the surface to ensure the beam's hardness and corrosion resistance. Existing refrigerator beam surface strengthening devices mainly consist of a conveying mechanism, a pre-treatment unit, and a spraying strengthening unit. During operation, the conveying mechanism first transports the beam to the pre-treatment unit for cleaning and degreasing. Then, the beam is transported to the spraying strengthening unit for the strengthening layer spraying. The spraying strengthening unit has a fixing clamp inside. After the beam enters, the clamp first clamps it, and then sprays it by lifting and rotating the beam, ensuring uniform coating on the beam surface.

[0003] Existing application number CN202422131897.3 discloses a spraying device for metal surface treatment, relating to the field of metal surface treatment technology. It includes a support rod, with a movable spraying mechanism at the bottom end of the support rod. The movable spraying mechanism includes a slider, which is welded to the bottom end of the support rod. A slide rail is movably connected to the inner wall of the slider, and fixing blocks are welded to both ends of the slide rail. A groove is formed on the top of each fixing block. This invention, through the movable spraying mechanism, enables the movement of the spray head. During use, the motor drives the slider to slide along the slide rail. The slider's movement on the slide rail ensures smoother and more stable spraying of the spray head, preventing uneven cooling caused by spraying in only one direction and ensuring the device's cooling effect.

[0004] Based on the above, existing refrigerator beam surface strengthening treatment devices are prone to skew during transport because the beams are mostly long and narrow, which affects the precise positioning and stable clamping of the beams by subsequent fixtures. Although some devices are equipped with positioning mechanisms, these mechanisms usually rely on a separate drive mechanism to operate, which not only increases the manufacturing cost of the equipment but also increases the overall operating load of the device. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a surface strengthening treatment device for the refrigerator center beam. This addresses the shortcomings of existing surface strengthening devices for refrigerator center beams, which, due to the center beam's elongated shape, are prone to skew during transport, thus affecting the precise positioning and stable clamping of the center beam by subsequent fixtures. While some devices are equipped with positioning mechanisms, these mechanisms typically rely on a separate drive mechanism, increasing both manufacturing costs and the overall operational load of the device.

[0006] The purpose and effect of this utility model's refrigerator beam surface strengthening treatment device are achieved by the following specific technical means: A surface strengthening treatment device for the center beam of a refrigerator includes a surface spraying body, a pretreatment mechanism, a conveying mechanism, a driving mechanism, pneumatic push rods, positioning plates, positioning components, and a swinging component. The pretreatment mechanism is fixedly installed on one side of the surface spraying body; the conveying mechanism is installed inside the surface spraying body and the pretreatment mechanism; two sets of driving mechanisms are provided, and the two sets of driving mechanisms are fixedly installed on both sides inside the surface spraying body; two sets of pneumatic push rods are provided, and the two sets of pneumatic push rods are fixedly installed at the ends of the two sets of driving mechanisms; two sets of positioning plates are provided, and the two sets of positioning plates are located at one end of the two sets of pneumatic push rods; the positioning component is located inside the surface spraying body; and the swinging component is located inside the surface spraying body.

[0007] Furthermore, the positioning component includes: a transmission plate and a hinge shaft. The transmission plate is provided in two sets, and the two sets of transmission plates are fixedly connected to the top ends of two sets of pneumatic push rods. The hinge shaft is provided in two sets, and the two sets of hinge shafts are rotatably connected inside the two sets of transmission plates. The two sets of hinge shafts are respectively fixedly installed inside the two sets of positioning plates.

[0008] Furthermore, the positioning component also includes: a trigger plate and an elastic torsion spring. The trigger plate is provided in two sets, and the two sets of trigger plates are hinged to the inner side of the two sets of positioning plates. The elastic torsion spring is provided in two pairs. One end of the two pairs of elastic torsion springs is fixedly connected to the outer side of the two sets of hinge shafts, and the other end of the two pairs of elastic torsion springs is fixedly connected to the inside of the two sets of transmission plates.

[0009] Furthermore, the positioning component also includes a sensor, wherein two sets of sensors are provided, and the two sets of sensors are fixedly installed inside the two sets of positioning plates.

[0010] Furthermore, the swing assembly includes: guide rods, drive clamps, and elastic elements. Two pairs of guide rods are provided, and the two pairs of guide rods are slidably connected inside the two sets of transmission plates. Two sets of drive clamps are provided, and the two sets of drive clamps are respectively fixedly installed on the top ends of the two pairs of guide rods. Two pairs of elastic elements are provided, with one end of the two pairs of elastic elements fixedly connected to the end of the two pairs of guide rods, and the other end of the two pairs of elastic elements fixedly connected to the back of the two sets of transmission plates.

[0011] Furthermore, the swing assembly also includes: a drive rod and a drive rack.

[0012] Furthermore, the swing assembly also includes a driven gear, wherein two sets of driven gears are provided, and the two sets of driven gears are coaxially and fixedly connected to the outside of two sets of hinge shafts, and the driven gears and the drive rack mesh with each other.

[0013] Compared with the prior art, the present invention has the following beneficial effects: First, this utility model has a positioning component. The positioning plate intercepts the long strip beam during transportation at both ends. With the linkage of the trigger plate and the sensor, it can accurately determine whether the beam is in a stable lateral posture, effectively solving the problem of beam skew during transportation and ensuring the accuracy of subsequent clamping and positioning. At the same time, the elastic torsion spring can drive the trigger plate to automatically reset without manual intervention, improving the continuity of positioning.

[0014] Secondly, this utility model has a swing component. By using the reaction force when the drive clamping plate contacts the middle beam, the drive rod, drive rack and driven gear are linked to drive the positioning plate to fold. Without the need for an additional separate drive mechanism, the positioning plate can avoid the end of the middle beam, which reduces the manufacturing cost of the equipment and reduces the operating load of the device.

[0015] This invention has the advantages of rapid positioning, simple structure, and avoidance of obstruction. While achieving precise positioning of the center beam, it avoids the positioning structure from obstructing the spraying area, ensuring the surface strengthening treatment effect. Moreover, the overall structure is compact and adaptable to the processing requirements of long strip center beams, improving the practicality and economy of the device. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1

[0024] As attached Figure 1 To be continued Figure 6 As shown: This utility model provides a surface strengthening treatment device for the middle beam of a refrigerator, including a surface spraying body 1, a pretreatment mechanism 2, a conveying mechanism 3, a driving mechanism 4, a pneumatic push rod 5, a positioning plate 6, and a positioning component. The pretreatment mechanism 2 is fixedly installed on one side of the surface spraying body 1; the conveying mechanism 3 is installed inside the surface spraying body 1 and the pretreatment mechanism 2; two sets of driving mechanisms 4 are provided, and the two sets of driving mechanisms 4 are fixedly installed on both sides inside the surface spraying body 1; two sets of pneumatic push rods 5 are provided, and the two sets of pneumatic push rods 5 are fixedly installed at the ends of the two sets of driving mechanisms 4; two sets of positioning plates 6 are provided, and the two sets of positioning plates 6 are located at one end of the two sets of pneumatic push rods 5; the positioning component is located inside the surface spraying body 1.

[0025] The positioning assembly includes: a transmission plate 501 and a hinge shaft 601. Two sets of transmission plates 501 are provided, and the two sets of transmission plates 501 are fixedly connected to the top ends of two sets of pneumatic push rods 5. Two sets of hinge shafts 601 are provided, and the two sets of hinge shafts 601 are rotatably connected inside the two sets of transmission plates 501. The two sets of hinge shafts 601 are respectively fixedly installed inside the two sets of positioning plates 6.

[0026] The positioning assembly also includes: a trigger plate 602 and an elastic torsion spring 6021. Two sets of trigger plates 602 are provided, and the two sets of trigger plates 602 are hinged to the inner side of the two sets of positioning plates 6. Two pairs of elastic torsion springs 6021 are provided. One end of the two pairs of elastic torsion springs 6021 is fixedly connected to the outer side of the two sets of hinge shafts 601, and the other end of the two pairs of elastic torsion springs 6021 is fixedly connected to the inside of the two sets of transmission plates 501.

[0027] The positioning component also includes a sensor 603, of which two sets are provided, and the two sets of sensors 603 are fixedly installed inside the two sets of positioning plates 6.

[0028] The specific usage and function of this embodiment are as follows: Under normal conditions, the positioning plate 6 and the transmission plate 501 form a 90° angle, and the elastic torsion spring 6021 is in its natural state, providing reset support for the trigger plate 602. When the conveying mechanism 3 conveys the middle beam, and after the middle beam has been pre-treated by the pre-treatment mechanism 2, it continues to be conveyed into the surface spraying body 1. The positioning plates 6 located on both sides of the conveying mechanism 3 will form positioning interception at both ends of the middle beam, guiding the middle beam to gradually be in the middle position of the two sets of pneumatic push rods 5. After the two ends of the middle beam contact the positioning plates 6, under the thrust of the continuous conveying of the conveying mechanism 3, the ends of the middle beam will exert pressure on the trigger plate 602, causing the trigger plate 602 to swing against the elastic force of the elastic torsion spring 6021, and simultaneously trigger the sensor 603. Only when both sets of sensors 603 are compressed can it be determined that the two ends of the middle beam are parallel to the positioning plate 6 and the middle beam is in a stable lateral posture. At this time, the controller inside the surface spraying body 1 will synchronously control the conveying mechanism 3 to stop running, and at the same time start the pneumatic push rod 5 to drive the transmission plate 501 to clamp and fix the two ends of the middle beam. At this time, the drive mechanism 4 drives the clamped middle beam to rise. After the surface spraying body 1 sprays the middle beam, the pneumatic push rod 5 releases the middle beam, causing the middle beam to fall onto the upper part of the conveying mechanism 3 for conveying. The trigger plate 602 returns to the initial position under the reset action of the elastic torsion spring 6021, which is convenient for the positioning operation of the next middle beam. Example 2

[0029] Based on Example 1, such as Figures 1 to 6 As shown, it also includes: a swing assembly, which is disposed inside the surface spraying body 1.

[0030] The swing assembly includes: guide rods 5021, drive clamps 502, and elastic elements 5022. Two pairs of guide rods 5021 are provided, and the two pairs of guide rods 5021 are slidably connected inside the two sets of transmission plates 501. Two sets of drive clamps 502 are provided, and the two sets of drive clamps 502 are respectively fixedly installed on the top ends of the two pairs of guide rods 5021. Two pairs of elastic elements 5022 are provided, one end of the two pairs of elastic elements 5022 is fixedly connected to the end of the two pairs of guide rods 5021, and the other end of the two pairs of elastic elements 5022 is fixedly connected to the back of the two sets of transmission plates 501.

[0031] The swing assembly also includes: a drive rod 5023 and a drive rack 5024. Two sets of drive rods 5023 are provided, and the two sets of drive rods 5023 are respectively fixedly installed on the back of the two sets of drive clamps 502. The two sets of drive rods 5023 are respectively slidably connected inside the two sets of transmission plates 501. Two sets of drive racks 5024 are provided, and the two sets of drive racks 5024 are respectively fixedly installed on the inner side of the two sets of drive rods 5023.

[0032] The swing assembly also includes a driven gear 6011, which is provided in two sets. The two sets of driven gears 6011 are coaxially fixedly connected to the outside of the two sets of hinge shafts 601. The driven gears 6011 and the drive rack 5024 mesh with each other.

[0033] The specific usage and function of this embodiment are as follows: When the pneumatic pusher 5 pushes the drive clamp 502 towards the middle beam to clamp it, the drive clamp 502 first contacts both ends of the middle beam. Under the reaction force generated at both ends of the middle beam, the drive clamp 502 moves towards the transmission plate 501, during which the elastic element 5022 is stretched simultaneously. At the same time, the guide rod 5021 provides stable guidance as the drive clamp 502 moves, preventing the drive clamp 502 from deviating. As the drive clamp 502 moves, it simultaneously drives the drive rod 5023 to slide along the inside of the transmission plate 501. The drive rod 5023 then drives the drive rack 5024, which is fixed to it, to move in the same direction. Since the drive rack 5024 meshes with the driven gear 6011, the movement of the drive rack 5024 will drive the driven gear 6011 to rotate. Since the driven gear 6011 is coaxially fixed with the hinge shaft 601, it will simultaneously drive the hinge shaft 601 to rotate. The rotation of the hinge shaft 601 further drives the positioning plate 6 to swing, eventually causing the positioning plate 6 to fold 180° and move away from the position of the drive clamp 502. This effectively prevents the positioning plate 6 from obstructing the end area of ​​the middle beam and prevents it from affecting the effect of subsequent surface strengthening treatment of the middle beam.
