Parallel seam welding repairing and plugging device

[0024] Example 1:

[0025] Such as Figure 1 to Figure 2 As shown, a parallel seam welding rework and plugging device includes a box body 1, and a working table 2 is movably arranged in the box body 1. The working table 2 can be rotated and moved up and down. The rotation and up and down movement of the working table 2 can be achieved by a motor and The electric telescopic pole is realized. There are a number of regularly arranged clamps on the workbench 2. The clamps are used to clamp the repaired products. The horizontal clamps form a horizontal clamp group, and the vertical clamps form a vertical clamp group. The number of horizontal clamps and the vertical clamps The number of seat groups is equal.

[0026] The box body 1 is provided with a liquid coating mechanism which can be moved left and right through the shift mechanism, which is used for gluing the repaired product and clearing the surface of the repaired product after the coating is completed. Specifically, the liquid coating mechanism includes a mounting plate 8 and a number of liquid coating parts arranged on it. The liquid coating part includes a liquid storage chamber 5 and two liquid outlet heads 6, which are respectively connected to the liquid storage chamber 5 Connected, the number and position of the liquid application parts and the horizontal clamp seat group are matched, and the distance between the two liquid outlet heads 6 is matched with the size of the repaired product, so that the two liquid outlets 6 can just touch the two sides of the repaired product. Seam area.

[0027] Specifically, the left and right spaces of the liquid storage chamber 5 are divided into a glue application cavity 3 and a cleaning cavity 4, and the glue application cavity 3 and the cleaning cavity 4 respectively store anaerobic glue and cleaning liquid. The bottoms of the glue application cavity 3 and the cleaning cavity 4 are respectively connected to one end of the L-shaped tube 9, and the two L-shaped tubes 9 are respectively provided with valves. The two L-shaped tubes 9 are arranged oppositely and the other ends are connected to one end of the pumping tube. The pumping pipe is provided with a micro pump, and the other end of the pumping pipe is also connected to one end of the two inverted L-shaped pipes 10 through a three-way connection, and the other end of the two inverted L-shaped pipes 10 are respectively connected to the liquid outlet 6.

[0028] The working principle is as follows: clamp the repaired product on the holder, move the workbench 2 up so that the repaired product is flush with the liquid discharge head 6, and control the liquid coating mechanism to move to the right through the shift mechanism, so that the liquid discharge head 6 and the repaired product Side contact. When applying glue, open the valve of the glue chamber 3L-shaped tube 9 and start the micro-pump to pump the anaerobic glue from the glue chamber 3 to the liquid head 6. At the same time, the shift mechanism drives the liquid application parts to move to the right to complete a set of horizontal clamps. Glue the symmetrical side of the repaired product of the seat assembly, and then rotate the clamp base 3 by 90°, and the shift mechanism will drive the liquid-applied part to move back horizontally to complete the gluing of the symmetrical side of the repaired product of a vertical clamp set. Glue of the repaired product in the holder, the anaerobic glue penetrates into the air leakage gap in the weld area of ​​the repaired product, and solidifies due to the isolation of air in the gap, thereby realizing the plugging of the weld area. Similar to the working principle of glue application, when cleaning glue, open the valve of the cleaning chamber 4L-shaped tube 9 and start the micro pump to pump the cleaning liquid from the cleaning chamber 4 to the liquid outlet 6, and the shift mechanism drives the liquid application part to move to the right to complete Clear glue on the symmetrical side of the repaired product of a set of horizontal clamps, then rotate the clamp 3 by 90°, and the displacement mechanism will drive the liquid-applied parts to move back horizontally to complete the clearing of the symmetrical side of the repaired product of a vertical clamp. , At this point, the glue removal of all repaired products in the holder is completed.

[0029] Use anaerobic glue to brush the weld area instead of removing the cover for repair. Using the permeability and anaerobic curability of the anaerobic glue, the anaerobic glue penetrates into the air leakage gap in the weld area, insulates the air and solidifies in the gap, effectively plugging the leak , No need to remove the cover and replace the cover, reducing the cost and difficulty of repairing. At the same time, the liquid storage chamber 5 is divided into two chambers, which are respectively filled with glue liquid and cleaning liquid, which can quickly and conveniently remove the residual anaerobic glue on the surface of the reworked product. At the same time, the glue and the clear glue share the liquid outlet 6, which can be easily discharged. The liquid head 6 is also cleaned, which avoids the problem of clogging of the liquid head 6 due to glue, and there is no need to regularly disassemble the liquid head 6 for cleaning, thereby reducing device maintenance costs and maintenance work intensity.

[0030] Furthermore, since the gluing and clearing share the pumping pipe and the inverted L-shaped tube 10, the initial liquid of the gluing and clearing will be contaminated. The washing liquid treatment can be performed before the gluing and clearing treatment to remove the initial liquid Abandoned. To this end, the box body 1 is provided with a waste liquid collection chamber 11, and the upper end of the waste liquid collection chamber 11 is movably provided with an end cover 12. A vertical plate 13 is provided, and the top of the vertical plate 13 is higher than the mounting plate 8.

[0031] The working process of lotion treatment is as follows: before the glue/clear glue treatment, the liquid coating mechanism moves to the left, the mounting plate 8 abuts the vertical plate 13 and pushes the vertical plate 13 to move to the left, the end cap 12 moves to the left along with it, and the spring is compressed at this time , The waste liquid collection chamber 11 is opened, the corresponding valve is opened and the micro pump is started to discharge the first liquid into the waste liquid collection chamber 11, and then the liquid coating mechanism is moved to the right for glue/cleaning treatment, the spring rebounds, and the end cap 12 right Move and close the waste liquid collection chamber 11.

[0032] Example 2:

[0033] Such as figure 1 with image 3 As shown, in order to speed up the curing speed of the anaerobic adhesive, in this embodiment, an auxiliary curing mechanism is movably provided in the box 1 through a shift mechanism. The auxiliary curing mechanism includes an air inlet shell 15 and an air outlet shell 16 arranged up and down. The box body 1 is provided with an air inlet and an air outlet. The air inlet shell 15 and the air outlet shell 16 are respectively provided with an air inlet 19 and an air outlet 20. The air inlet 19 and the air outlet 20 are respectively connected to the air inlet through a telescopic hose And the air outlet, the top inner wall of the air inlet shell 15 is provided with a number of stoppers 14 downwards. The number and position of the stoppers 14 match the clamp seats on the workbench 2. The stoppers 14 extend through the air outlet shell 16 to block The outer part of the block 14 is sleeved with a surrounding frame 17 at the same center. The surrounding frame 17 is connected to the bottom of the air inlet shell 15 and communicates with the air inlet shell 15. The surrounding frame 17 extends through the air outlet shell 16, and the bottom of the surrounding frame 17 is provided with air outlet A windshield frame 18 is sheathed in the center of the enclosure frame 17. The windshield frame 18 is connected between the bottom of the air outlet shell 16 and the bottom of the enclosure frame 17 and communicates with the air outlet shell 16.

[0034] It should be noted that the structure of the enclosure frame 17 and the windshield frame 18 is as image 3 As shown, the bottom end of the enclosure frame 17 is lower than the bottom end of the stopper 14, the opening at the bottom end of the enclosure frame 17 matches the size of the repaired product, the size of the stopper 14 is smaller than the size of the repaired product, and the stopper 14 is used to cover the unrepaired area on the surface of the repaired product .

[0035] The working principle is as follows: the auxiliary curing mechanism moves to the left above the workbench 2, and the workbench 2 moves up so that the repaired product on the clamp seat contacts the stopper 14. The hot air enters the air inlet shell 15 from the air inlet and passes through the enclosure 17 and the stopper 14. Blow down to the side of the reworked product, heat the reworked area to accelerate the curing speed of the anaerobic glue, and enter the channel between the windshield frame 18 and the enclosure frame 17 through the air outlet, enter the air outlet shell 16 and discharge through the air outlet. The auxiliary curing mechanism is set to heat the repaired product, accelerate the curing speed of the anaerobic adhesive, and improve the repair efficiency. At the same time, the use of the stopper 14 and the enclosure 17 enables local heating of the repaired area, which has high heating efficiency and heats the repaired product. The impact is small.

[0036] In all the above embodiments, the displacement mechanism is the electric slide rail 7, which is arranged on the top of the box 1, and the top surface of the mounting plate 8/the top surface of the air inlet shell 15 is connected with the sliding block of the electric slide rail 7.
