Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling tables, in particular to a copper pipe welding tooling table. Background Technique

[0002] During the production process of refrigeration equipment, the welding process of copper pipes is involved, that is, multiple copper pipes need to be combined together by brazing.

[0003] At present, when welding copper pipes, it requires the cooperation of multiple workers. The workers sit around a circular tooling table in sequence, and then each is responsible for inserting copper pipes with different diameters onto the tooling, and then transferring the tooling to another person's position for welding. During the welding process, the flame gun will emit strong arc light. Since the welding personnel wear goggles, the arc light has no great visual stimulation to them, but the workers responsible for assembly need to endure the interference and stimulation of the arc light. Then, during the long-term work process, it will cause visual discomfort, and seriously affect the work efficiency.

[0004] Therefore, there is an urgent need for a copper pipe welding tooling table to reduce the visual interference and stimulation of the arc light on the assembly workers during welding and ensure the work efficiency. Content of the Utility Model

[0005] In view of the above technical problems, the utility model provides a copper pipe welding tooling table to solve the problem that the existing copper pipe welding tooling table has no arc light protection measures, resulting in great visual interference to the assembly personnel caused by the arc light.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A copper pipe welding tooling table includes a frame. A fixed seat is provided on the frame. A support bearing is provided on the fixed seat. A turntable is installed on the support bearing. A plurality of assembly tables are detachably installed on the turntable. A driving gear is engaged with the support bearing. A driving motor is matched with the driving gear. A rotating hole is opened in the center of the turntable. A column is vertically fixed through the rotating hole by the fixed seat. A first mounting arm and a second mounting arm are circumferentially provided on the column. Baffles are detachably installed on one side of the first mounting arm and the second mounting arm close to the turntable. The baffle and the turntable form a welding chamber. A feeding gap is provided between the baffle and the turntable.

[0008] Further, a sector-shaped top plate is provided between the tops of the first mounting arm and the second mounting arm. A dust suction port is opened on the sector-shaped top plate. A negative pressure pipe is installed on the dust suction port. The negative pressure pipe is used to connect with a negative pressure device.

[0009] Further, the width of the feeding gap is greater than the total height of the copper pipes on the assembly table.

[0010] Further, a plurality of insertion posts are arranged in a rectangular shape on one side of the assembly table close to the turntable, and a plurality of groups of insertion holes capable of accommodating the insertion posts are formed on the turntable.

[0011] Further, the included angle between the first mounting arm and the second mounting arm is 90 degrees.

[0012] Further, the baffles are connected to the first mounting arm and the second mounting arm by bolts.

[0013] In summary, the beneficial technical effects of the present utility model are as follows:

[0014] (1) By using the baffles arranged on the first mounting arm and the second mounting arm to form a fan-shaped welding chamber, when welding the copper pipe, the direct contact between the assembly personnel and the arc light is blocked by the baffles, thereby avoiding the visual interference and stimulation of the arc light to the assembly personnel, eliminating the visual discomfort of the assembly personnel, and further improving the assembly efficiency.

[0015] (2) By using the fan-shaped top plate arranged at the tops of the first mounting arm and the second mounting arm and the dust suction openings formed on the top plate, the heat and harmful gases released during welding can be discharged in time through the negative pressure device, thereby reducing the problem of local temperature rise caused by the outward diffusion of heat, and effectively reducing the physical consumption and labor intensity of the assembly personnel.

[0016] (3) By using the cooperation of the insertion holes and the insertion posts, the number of workstations can be flexibly increased on the turntable according to the working conditions during the welding of the copper pipe, so as to improve the working efficiency. Description of the Drawings

Detailed Embodiments

[0022] The present utility model will be clearly and completely described below in conjunction with embodiments.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the attached drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0024] In the description of the embodiments, unless otherwise clearly specified and limited, terms such as "set" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or connected through an intermediate medium, or the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] Refer to the attached Figures 1-4 , as shown is a copper pipe welding workbench, including a frame 1. A fixed seat 2 is fixed at the center of the top of the frame 1 through a support beam. A support bearing 3 is installed on the fixed seat 2. A driving gear 4 is engaged with the outer circular gear of the support bearing 3. A driving motor 5 is cooperatively provided on the driving gear 4. The driving motor 5 is installed on the corresponding support beam. Among them, a turntable 6 is installed on the outer circle of the support bearing 3 through bolts. When in use, the driving motor 5 drives the outer circle of the support bearing 3 to rotate through the driving gear 4, and the support bearing 3 further drives the turntable 6 to rotate to realize the transfer of the copper pipe;

[0026] A plurality of assembly stations 17 are circumferentially arranged on the turntable 6. Positioning columns 19 are provided on the assembly stations 17. When assembling the copper pipes, the respective copper pipes are inserted onto the positioning columns 19, and then are transferred by driving the turntable 6;

[0027] Furthermore, a rotating hole 7 is opened at the center of the turntable 6. A column 8 is vertically fixed to the fixed seat 2 through a fixing hole. The diameter of the column 8 is smaller than that of the rotating hole 7, so as to avoid friction between the turntable 6 and the column 8 when the turntable 6 rotates. A first mounting arm 9 and a second mounting arm 10 are circumferentially provided at the top end of the column 8. The included angle between the first mounting arm 9 and the second mounting arm 10 is 90 degrees. One baffle 11 is connected to each of the ends of the first mounting arm 9 and the second mounting arm 10 close to the turntable 6 through bolts. At this time, a fan-shaped welding chamber is formed by the two baffles 11 and the turntable 6. When the turntable 6 transfers the copper pipe to the welding chamber through the assembly station 17, welding can be carried out. The arc light generated during the welding process is blocked by the baffles 11, avoiding the interference and stimulation of the arc light to the vision of the assembly personnel, reducing the visual discomfort, and thus improving the assembly efficiency and quality;

[0028] In addition, a feeding gap 15 is left between one end of the baffle 11 close to the turntable 6 and the turntable 6. At the same time, the width of the feeding gap 15 is greater than the total height of the copper tubes on the assembly table 17, thus avoiding the interference between the copper tubes and the baffle 11;

[0029] Furthermore, a sector-shaped top plate 12 is bolted between the tops of the first mounting arm 9 and the second mounting arm 10. At the same time, a dust suction port 13 is provided on the sector-shaped top plate 12, and a negative pressure pipe 14 is installed on the dust suction port 13. The negative pressure pipe 14 is connected to a negative pressure device, such as an outdoor exhaust fan. When heat and harmful gases are generated during welding, they can be discharged in time through the negative pressure device, which can reduce the outward diffusion of heat, avoid the increase in local temperature and the physical consumption of assembly workers, and at the same time isolate the baking of the brazing flame on the front of the assembly workers;

[0030] At the same time, in order to facilitate the fixation of the assembly table 17 and the turntable 6, four insertion posts 18 are provided in a rectangular shape on one side of the assembly table 17 close to the turntable 6. At the same time, multiple groups of insertion holes 16 matching the insertion posts 18 are provided in a circular arrangement on the turntable 6. When installing the assembly table 17, the fixation can be quickly achieved through the insertion and matching of the insertion posts 18 and the insertion holes 16, which not only improves the fixation speed of the assembly table 17 but also avoids the problem of sliding between the assembly table 17 and the turntable 6.

[0031] During use, according to the working conditions, the required assembly table 17 is inserted onto the turntable 6 through the insertion posts 18. Then, the assembly workers sequentially insert various required copper tubes onto the positioning posts 19 of the assembly table 17. Then, the welding workers control the driving motor 5 to start through the foot pedal and drive the turntable 6 to rotate. The turntable 6 further moves the assembly table 17 with the inserted copper tubes through the feeding gap 15 and reaches between the two baffles 11. Then, the welding workers can weld the copper tubes. During the welding process, the arc light is blocked by the baffles 11 from stimulating and interfering with the assembly workers visually, ensuring the assembly efficiency and quality. On the other hand, the heat and harmful gases generated during welding are discharged in time through the negative pressure device, reducing the physical consumption of the assembly workers and the welding workers by the heat and ensuring the workshop environment.

[0032] The above is only the preferred specific implementation manner of the present invention, and does not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
