Description

Technical Field

[0001] The utility model belongs to the technical field of splash prevention for caulking welders, and particularly relates to a splash prevention device for caulking welders. Background Art

[0002] A caulking welder is an automated welding equipment specially used for welding the gaps in plates. It is usually used in shipbuilding, bridge construction, pressure vessel manufacturing, and large steel structure projects. It completes high-quality welding work at the gaps between plates by continuously feeding in filler metal materials. The anti-splash device of a caulking welder refers to an auxiliary equipment installed on the caulking welder. Its main function is to prevent splashing molten metal and other welding impurities from flying around during welding, thereby protecting the safety of operators, maintaining the cleanliness of the working environment, and protecting important components near the welding area from damage. The existing anti-splash device of a caulking welder cannot adjust the length of the protective cover according to the actual height of the welding material, and has the problem of low adaptability.

[0003] For example, the utility model with announcement number CN209532398U discloses a splash-proof device for a seat-type resistance spot welding machine, a frame, and a protective plate. The frame is a hexahedral frame structure, the protective plate is installed on the frame, and the ground and one side of the frame are not installed with a protective plate. In this patent scheme, the length of the protective plate used to prevent splashing is fixed and cannot be flexibly expanded. In different welding operations, the material size used for caulking welding may vary greatly, and the fixed-length protective cover may not be able to completely cover the welding area, resulting in a weakened or failed protective effect. Utility Model Content

[0004] In view of this, the utility model aims to provide a splash-proof device for a caulking welder to address the deficiencies in the prior art. The device can flexibly adjust the length of the protective cover according to the height of the material to be caulked, thereby ensuring that sufficient protection can be provided in welding operations at any height, avoiding the harm of splashes to personnel and the environment, and greatly improving its adaptability.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a splash-proof device for a caulking welding machine, comprising a protective cover, a avoidance port is provided at the upper end of the protective cover, a sliding cover is slidably connected in a sliding groove provided inside the protective cover, an observation window is provided in a mounting port provided on the front side of the sliding cover, a locking mechanism for locking the sliding cover is provided on the left and right sides of the protective cover, a scraping mechanism is provided for sliding inside the sliding cover, the locking mechanism comprises rotating columns respectively rotatably arranged on the left and right sides of the protective cover, a pull plate is fixedly sleeved on the outer arc surfaces of the two rotating columns, locking columns are provided on the opposite inner sides of the two pull plates, evenly distributed locking holes are provided on the left and right sides of the sliding cover, the two locking columns respectively pass through the through holes provided inside the protective cover and are plugged into an adjacent locking hole, and limit disks are provided on the opposite outer ends of the two locking columns, and elastic drive components are respectively provided between the pull plate and the limit disk, and the elastic drive components include springs respectively arranged between the pull plate and the limit disk, and the two springs are respectively sleeved on the corresponding outer arc surfaces of the rotating columns.

[0006] As a further improvement of the utility model, a mounting frame is welded and fixed to the upper end of the protective cover, and mounting bolts are welded and fixed to the four corners of the upper end of the mounting frame.

[0007] As a further improvement of the utility model, the scraping mechanism includes a scraping brush frame slidably arranged inside the sliding cover, the scraping brush frame is installed in cooperation with the inner wall of the sliding cover, a rotating seat is arranged on the rear side of the scraping brush frame, the interior of the rotating seat is rotatably connected with a connecting frame, a frame plate is arranged on the rear side of the sliding cover, a rotating frame is slidably arranged inside the frame plate, the upper end of the connecting frame is rotatably connected to the interior of the rotating frame, a screw rod is rotatably arranged inside the frame plate, the rotating frame is threadedly connected to the screw rod, an electric drive unit for driving the screw rod to rotate is arranged on the left side of the frame plate, the electric drive unit includes a motor rotatably arranged on the left side of the frame plate, and the output shaft of the motor is connected to the left end of the screw rod through a coupling.

[0008] As a further improvement of the utility model, a control panel is arranged on the front side of the protective cover, and the motor is electrically connected to the control panel.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] Firstly, by aligning the welding gun stand of the caulking welder with the avoidance port of the anti-spatter device, the protective cover and the sliding cover can prevent sparks from flying when the material is caulking and welding. Through the observation window, personnel can understand the progress of the caulking welding in real time, thereby achieving anti-splash when the caulking welder is in operation.

[0011] Secondly, by pulling the pull plates on both sides, the locking column is made to leave the inner wall of the locking hole, and then the pull plates are rotated to make the locking column rotate out, and then the pull plates are released. The locking column is contacted with the surface of the protective cover through the rebound of the spring, and then the sliding cover is pulled to the appropriate extension length, and then the pull plates are pulled and rotated to align the locking column with the locking hole. At this time, the spring is in a compressed state, and then the pull plates are released. At this time, the spring rebounds quickly and drives the locking column on the pull plates to rebound quickly and insert into the locking hole opened inside the sliding cover, so as to lock the sliding cover and complete the extension of the protective length of the anti-splash device. The length of the protective cover can be flexibly adjusted according to the height of the material to be caulked and welded, ensuring that sufficient protection can be provided in welding operations at any height to avoid the harm of splashes to personnel and the environment, thereby greatly improving its adaptability.

[0012] Thirdly, by controlling the motor to run, the output shaft rotates to drive the screw to rotate, which can move the sliding frame to the right, so that the connecting frame inside it rotates and expands, driving the scraper frame on the rotating seat to move downward, and the welding slag adhered to the inside of the sliding cover can be scraped off, reducing the cleaning burden of personnel and extending the service life of the anti-splash device.

[0013] Fourthly, the anti-spatter device can be quickly installed on the welding gun stand of the caulking welder through the mounting bolts on the mounting frame, which is convenient for personnel to install it. BRIEF DESCRIPTION OF THE DRAWINGS
