[0037] As Figure 1 In combination Figure 2 As shown in the drawings, the utility model provides a transmission device for driving material rack rotation, including first transmission member 2, second transmission member 3 and drive assembly, first transmission member 2 is connected with the output of drive assembly, and the axial interval of first transmission member 2 is equipped with a plurality of first matching post 202 along the axial extension of first transmission member 2, second transmission member 3 is connected with the transmission rod 6 of material rack, and the circumferential interval of second transmission member 3 is equipped with a plurality of second matching post 302 along the axial extension of second transmission member 3, and first matching post 202 is engaged with second matching post 302.

[0038] Compared with the prior art, the transmission device provided by the utility model has the following advantages:

[0039] The transmission device provided by the utility model, the first transmission member 2 in the application is formed with a first engaging column 202, the second transmission member 3 is formed with a second engaging column 302, and the first engaging column 202 and the second engaging column 302 are engaged, so when the driving assembly drives the first transmission member 2 to rotate, the first engaging column 202 can be driven to rotate, thereby transmitting power to the second engaging column 302.

[0040] Under the action of the first engaging column 202, the second engaging column 302 moves, thereby driving the entire second transmission member 3 to rotate, and since the transmission rod 6 of the rack in the application is connected with the second transmission member 3, when the second transmission member 3 rotates, the transmission rod 6 can be driven to rotate, thereby driving the entire rack.

[0041] It can be understood that since the output end of the driving assembly and the transmission rod 6 in the application are only provided with the first transmission member 2 and the second transmission member 3 having the intermeshing structure, the transmission device provided by the application can directly transmit the power output by the driving assembly from the first transmission member 2 to the second transmission member 3, and then from the second transmission member 3 to the rack, that is, two-stage power transmission is realized, compared with the three-stage transmission adopted at present, the number of structures participating in transmission is reduced, the manufacturing cost of the entire device is reduced, and the failure rate during operation can be reduced to a certain extent.

[0042] Optionally, as shown in Figure 1 Combining Figure 2 It is shown that the first transmission member 2 in the application includes a first base disc 201, and the first engaging column 202 is formed at the edge of the first base disc 201; the first base disc 201 is circular, and the axis of the output end of the driving assembly is collinear with the center of the first base disc 201.

[0043] Through the circular first base disc 201, installation space can be provided for the first engaging column 202, and a plurality of first engaging columns 202 can be uniformly distributed at the edge of the first base disc 201. By making the axis of the output end of the driving assembly collinear with the center of the first base disc 201, the first base disc 201 can be uniformly rotated when being driven by the driving assembly.

[0044] It should be noted here that, as shown in Figure 1 The driving assembly in the application includes a driving member 1, and the driving member 1 is a motor. Since the position of the motor is fixed and has a certain distance from the coating cabin of the continuous coating line, in actual application, the output end of the motor can be connected with the first transmission member 2 through a transmission structure such as an output shaft to complete power transmission.

[0045] Optionally, as shown in Figure 1 Combining Figure 2As shown, the first fitting column 202 in the application is a cylindrical structure, and the end face of the end of the first fitting column 202 away from the first base disc 201 is a spherical end face.

[0046] By making the first fitting column 202 a cylindrical structure, the force on the first fitting column 202 and the second fitting column 302 when they are in contact can be more uniform, thereby ensuring the transmission of power. In some embodiments, by making the end face of the first fitting column 202 a spherical end face, the contact between the first fitting column 202 and the second fitting column 302 can be smoother during assembly, and also serves as a guide. In addition, it can also reduce the problem of damage to the second fitting column 302 caused by contact, affecting the uniformity of stress or structural failure damage.

[0047] Preferably, as Figure 1 In combination Figure 2 As shown, the first fitting column 202 in the application includes a long column 2021 and a short column 2022, the long column 2021 and the short column 2022 are alternately arranged along the circumference of the first base disc 201, and the end face of the end of the long column 2021 away from the first base disc 201 is a spherical end face, and the end face of the end of the short column 2022 away from the first base disc 201 is a guide inclined surface 2023.

[0048] The long column 2021 and the short column 2022 in the application can be in contact with the second fitting column 302 after assembly, thereby achieving balanced transmission of power. However, during the assembly stage, the second fitting column 302 and the first fitting column 202 are easily aligned, resulting in a collision between the two during assembly. Therefore, the long column 2021 and the short column 2022 are alternately arranged in the application, so that when one second fitting column 302 contacts the long column 2021, another second fitting column 302 contacts the short column 2022. Under the action of the guide inclined surface 2023, the first base disc 201 is rotated with a moving amplitude, and the first fitting column 202 and the second fitting column 302 form an engaged state, thereby achieving smooth assembly of the two.

[0049] Optionally, as Figure 1 As shown, the second transmission member 3 in the application includes a second base disc 301, and the second fitting column 302 is formed on the edge of the second base disc 301; the second base disc 301 is circular, and the axis of the transmission rod 6 is collinear with the center of the second base disc 301.

[0050] By providing a circular second base disc 301, installation space can be provided for the second fitting column 302, and multiple second fitting columns 302 can be uniformly distributed on the edge of the second base disc 301. By making the axis of the transmission rod 6 collinear with the center of the second base disc 301, the transmission rod 6 can be uniformly rotated when the second base disc 301 rotates, thereby making the rotation of the entire rack uniform and achieving uniform rotation.

[0051] Optionally, such as Figure 1 As shown, the second mating post 302 in this application has a cylindrical structure, and the end faces of the two ends of the second mating post 302 away from the second base plate 301 are spherical end faces.

[0052] By making the second mating post 302 a cylindrical structure, the force distribution when in contact with the first mating post 202 is more uniform, thus ensuring the transmission of power. In some embodiments, by making the end face of the second mating post 302 also a spherical end face, the contact between the second mating post 302 and the first mating post 202 can be made smoother during assembly, while also playing a certain guiding role. Furthermore, it can reduce the risk of damage to the first mating post 202 caused by contact, thus minimizing the possibility of affecting force balance or structural failure.

[0053] Preferably, such as Figure 1 As shown, the drive assembly in this application includes a drive member 1 and a first transmission block 4. The first transmission member 2 also includes a connecting shaft and a second transmission block 5. The output end of the drive member 1 is connected to the first transmission block 4. One end of the connecting shaft is connected to the second transmission block 5, and the other end is connected to the first base plate 201. The first transmission block 4 has a positioning groove, and the second transmission block 5 can enter the positioning groove and engage with the first transmission block 4.

[0054] In actual operation, the motor is connected to the first transmission component through the aforementioned output shaft. When the motor starts, it can drive the first transmission component to rotate. Since the first transmission component in this application has a positioning groove, and the second transmission block 5 can enter the positioning groove and engage with the first transmission component, when the first transmission component rotates, it can drive the second transmission component to rotate. Furthermore, the second transmission component is connected to one end of the connecting shaft, and the other end of the connecting shaft is connected to the first base plate 201. Therefore, the rotation of the second transmission component can drive the first base plate 201 to rotate, thereby moving the second connecting pin 302 through the first mating pin 202 on the first base plate 201, thereby realizing the rotation of the second base plate 301, and finally realizing the rotation of the transmission rod 6.

[0055] It is understandable that when the transmission rod 6 rotates, the entire material rack rotates, thus completing the power transmission.

[0056] It should be further explained here that the connecting shaft and the second transmission component mentioned above in this application move with the material rack system. In the actual operation of the continuous coating line, when the material rack system enters the coating chamber, the second transmission component gradually approaches the first transmission component. When the second transmission component enters the positioning groove and is engaged, the drive component 1 is activated, thereby transmitting power to the transmission rod 6, thereby realizing the rotation of the material rack body and achieving a uniform coating process for the workpiece.

[0057] Further, the utility model also provides a rack system, including rack main part and above-mentioned transmission, rack main part includes rack and transmission rod 6, rack is arranged around transmission rod 6, and with transmission rod 6 fixed connection, transmission rod 6 one end is connected with second transmission member 3.

[0058] Among them, the rack system provided by the utility model further includes a carrier frame, the rack main body is arranged on the carrier frame, and the first transmission member 2 penetrates through the carrier frame and is connected with the driving assembly.

[0059] The rack system with the transmission device provided by the present application can have a more simple transmission structure, the transmission logic is more simple, the later maintenance is facilitated, and the production cost and maintenance cost can be reduced.

[0060] In the present application, the carrier frame is used to carry the rack main body, the rack main body can carry the workpiece to be plated, and the carrier frame is further provided with a walking wheel mechanism capable of realizing the walking of the overall rack system, the walking wheel mechanism drives the carrier frame to move, thereby realizing the synchronous movement of the rack main body and the first transmission member 2 and the second transmission member 3.

[0061] It can be understood that the driving assembly in the present application corresponds to the plating cabin in the plating line one by one, that is, during the walking of the rack system in the continuous plating line, the driving assembly is always in a fixed state, when the rack system is in place, the power transmission is realized by the combination of the first transmission member and the second transmission member, and when the plating is finished and the first transmission member and the second transmission member are separated, the rack main body no longer rotates until the driving assembly corresponding to the next plating cabin is combined.

[0062] The present application further provides a continuous plating line comprising the rack system described above.

[0063] Since the rack system in the present application adopts the transmission device, the continuous plating line in the present application has a more simple transmission process and transmission structure, thereby reducing the manufacturing cost of the overall continuous plating line.

[0064] The above is only a preferred embodiment of the utility model, and does not limit the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
