Description

Technical Field

[0001] This utility model relates to the technical field of coating equipment, specifically, to a welding fixture for the outer casing of a coating machine oven. Background Technology

[0002] After coating, the coating film is usually fed into an oven for drying. Typically, the outer frame of the oven is assembled manually and then welded together during production. However, manual assembly of the frame is prone to misalignment of the welds, resulting in large gaps. If the welds are not tight, hot air leakage can occur during oven use. Furthermore, manual operation is inefficient. Utility Model Content

[0003] In order to overcome the defects of the existing technology, this utility model provides a welding fixture for the outer box of a coating machine oven to solve the problems in the existing technology.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a welding fixture for the outer box of a coating machine oven, including a machine body, on which two first side plate positioning and fixing modules are slidably arranged, and a second side plate positioning and fixing module is slidably installed on the machine body between the two first side plate positioning and fixing modules. The two first side plate positioning and fixing modules can move synchronously in opposite directions, and the two second side plate positioning and fixing modules can move synchronously in opposite directions. The top view projections of the first side plate positioning and fixing modules and the second side plate positioning and fixing modules are perpendicularly distributed.

[0005] In the aforementioned welding fixture for the outer casing of a coating machine oven, both first side plate positioning and fixing modules include a first positioning side plate. The lower ends of both first positioning side plates are mounted on the machine body via a first slide rail slider. A first positive and negative threaded screw is threadedly connected to the two first positioning side plates via a first nut. One end of the first positive and negative threaded screw is connected to a first motor mounted on the machine body.

[0006] In the aforementioned welding fixture for the outer casing of a coating machine oven, a first electromagnet is installed on the side of each of the two first positioning side plates facing each other, and a first support plate installed on the first positioning side plate is provided below the first electromagnet.

[0007] In the aforementioned welding fixture for the outer casing of a coating machine oven, both second side plate positioning and fixing modules include second positioning side plates. The lower ends of both second positioning side plates are mounted on the machine body via second slide rail sliders. The two second positioning side plates are connected to second positive and negative threaded screws via second nuts. One end of the second positive and negative threaded screws is connected to a second motor mounted on the machine body.

[0008] In the aforementioned welding fixture for the outer casing of a coating machine oven, a second electromagnet is provided on one side of each of the two second positioning side plates facing each other, and a second support plate mounted on the second positioning side plate is provided below the second electromagnet.

[0009] The beneficial effects of this utility model are: the first side plate positioning and fixing module and the second side plate positioning and fixing module can be used to position and fix the oven frame. Since the second side plate positioning and fixing module is between the two first side plate positioning and fixing modules, the four oven frames can be moved to the middle position by the two opposing first side plate positioning and fixing modules and the two opposing second side plate positioning and fixing modules, so that the ends of the four oven frames can be spliced ​​together. The splicing efficiency is higher and the positioning is more accurate, reducing the gap width of different degrees at the splicing position, so as to facilitate subsequent welding by laser welding machine.

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0015] Combination Figures 1 to 3The illustrated welding fixture for the outer casing of a coating machine oven includes a body 1. Two first side plate positioning and fixing modules are slidably mounted on the body 1. A second side plate positioning and fixing module is slidably mounted on the body 1 between the two first side plate positioning and fixing modules. The two first side plate positioning and fixing modules can move synchronously in opposite directions, and the two second side plate positioning and fixing modules can also move synchronously in opposite directions. The top view projections of the first and second side plate positioning and fixing modules are perpendicular to each other. In this embodiment, the first and second side plate positioning and fixing modules can be used to position and fix the oven frame. Since the second side plate positioning and fixing module is located between the two first side plate positioning and fixing modules, the two opposing first side plate positioning and fixing modules and the two opposing second side plate positioning and fixing modules can drive the four oven frames to move towards the center position, so that the ends of the four oven frames can be spliced ​​together. This results in higher splicing efficiency and more accurate positioning, reducing the gap width of different degrees at the splicing position, which facilitates subsequent welding by a laser welding machine.

[0016] In this embodiment, both first side plate positioning and fixing modules include first positioning side plates 3. The lower ends of the two first positioning side plates 3 are mounted on the machine body 1 via first slide rail sliders 2. The two first positioning side plates 3 are threadedly connected to first positive and negative threaded screws 5 via first nuts 4. One end of the first positive and negative threaded screws 5 is connected to a first motor 6 mounted on the machine body 1. The first motor 6 drives the first positive and negative threaded screws 5 to rotate, thereby driving the two first positioning side plates 3 to move in opposite directions. A first electromagnet 12 is installed on the side of the two first positioning side plates 3 facing each other. A first support plate 13 is provided below the first electromagnet 12 and mounted on the first positioning side plate 3. The first support plate 13 can support the oven frame and can be fixed by the first electromagnet 12 to prevent displacement.

[0017] Both second side plate positioning and fixing modules include second positioning side plates 8. The lower ends of the two second positioning side plates 8 are mounted on the machine body 1 via second slide rail sliders 7. The two second positioning side plates 8 are threadedly connected to second positive and negative threaded screws 10 via second nuts 9. One end of the second positive and negative threaded screws 10 is connected to a second motor 11 mounted on the machine body 1. The second motor 11 can drive the second positive and negative threaded screws 10 to rotate, so that the two second positioning side plates 8 can move in opposite directions. A second electromagnet 14 is provided on the side of the two second positioning side plates 8 facing each other. A second support plate 15 is provided below the second electromagnet 14 and mounted on the second positioning side plate 8. The second support plate 15 can support the oven frame and can be fixed by adsorption by the second electromagnet 14.

[0018] In this embodiment, the length of the second positioning side plate 8 is less than the length of the first positioning side plate 3. During operation, in order to prevent the ends of each oven frame from being misaligned, the oven frame can be placed on the second tray 15 firstly. Since the two second positioning side plates 8 are located between the two first positioning side plates 3, the oven frame on the second tray 15 is aligned by first moving the first positioning side plate 3 towards the center. Then, the second electromagnet 14 is activated to attract and fix it. Then, the oven frame is placed on the first tray 13. The oven frame on the second tray 15 is aligned with the oven frame on the first tray 13 by moving the oven frame on the second tray 15 towards the first tray 13 and connecting the ends. Then, the first electromagnet 12 is activated to attract and fix it, preventing displacement during subsequent welding.
