Description

Technical Field

[0001] The invention discloses a light stud welding machine auxiliary device, belonging to the field of metal structure installation and construction of building engineering, in particular to a stud welding auxiliary device. Background Art

[0002] Studs are a kind of fasteners with high strength and rigidity connection, which are used in various steel structure projects and play a role of rigid combined connection in different connecting parts. Studs are generally used in conjunction with ceramic rings, and the ceramic rings need to be removed after the stud welding is completed. The studs are welded with a special welding machine, and the ceramic ring pressure rod provided by the welding machine is conventionally used to control the verticality. However, due to the small size of the studs, the studs are very easy to tilt during welding, which reduces the fastening performance of the studs. At the same time, the ceramic rings are conventionally knocked out one by one manually, which is inefficient. CN105880888A discloses a stud welding auxiliary device, including two circular support plates and three columns. During operation, the length of the columns is adjusted to ensure that the circular support plates are parallel to the surface of the steel member to be welded, and the circular support plates are tightly connected to the steel member to be welded through the permanent magnets at the bottom of the columns, so as to ensure the quality of the verticality of the stud welding. The device mainly relies on its own weight and the adsorption effect of the magnet at the bottom of the column to achieve its function, but it still has the following defects: 1. The length of the column is adjusted using a full-length thread, and the manual adjustment process is cumbersome; 2. It is tightly connected to the steel structure to be welded through a permanent magnet, but due to the adsorption effect of the magnet, it is more laborious to move the device; 3. The device only serves to ensure the verticality of the welding and does not have the function of assisting in breaking the ceramic ring. Summary of the invention

[0003] The problem to be solved by the present invention is to provide a stud welding auxiliary device which can not only ensure the welding verticality but also assist in breaking the ceramic ring. The technical solution is as follows:

[0004] A light bolt welding machine auxiliary device comprises an upper pressure plate and a lower base plate. The key technology is to install a movable telescopic rod between the upper pressure plate and the lower base plate, and to put a compression spring on the movable telescopic rod. A round hole is opened in the middle of the upper pressure plate, a limiting hole is opened on one side of the round hole, and a hole is opened in the middle of the lower base plate.

[0005] The movable telescopic rod comprises an outer sleeve and an inner rod, the outer sleeve and the inner rod are sleeved to form a rod member, and two ends of the rod member are respectively fixed to the upper pressing plate and the lower bottom plate.

[0006] The holes are circular holes with serrations.

[0007] A ceramic ring pressure rod fixing block is arranged above the upper pressure plate.

[0008] A ceramic ring pressing plate is arranged above the lower bottom plate.

[0009] The upper pressing plate, the lower bottom plate and the movable telescopic rod are made of light plastic steel plates.

[0010] The compression spring is made of a composite rubber spring.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The limiting holes of the upper pressure plate can effectively ensure that the welding gun is always kept vertically fixed during welding, so as to ensure that the studs are kept vertical to the surface of the steel structure to be welded; the circular holes of the lower base plate can be used to install studs and ceramic rings on the steel structure to be welded in advance, which is more convenient for positioning the welding machine.

[0013] 2. Through the elastic support system composed of movable telescopic rods and compression springs, when welding studs, it is only necessary to gently press the upper pressure plate at the same time to enhance the close connection between the lower base plate and the steel member to be welded, while ensuring the stability of the welding action and the quality of the stud welding. The structure is simple, but the design is ingenious and the operation is convenient.

[0014] 3. The setting of the ceramic ring pressure rod fixing block and the ceramic ring pressure plate further increases the convenience and reliability of operation.

[0015] 4. After the stud welding is completed, the entire auxiliary device can be rotated and the saw teeth in the circular hole of the lower bottom plate can be used to destroy the ceramic ring outside the stud, reducing the subsequent manual knocking-out process and improving construction efficiency.

[0016] 5. The light plastic steel plate is light in weight and the whole device is easy to move. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See also Figure 1 , Figure 2 A light stud welding machine auxiliary device comprises an upper pressing plate 1 and a lower bottom plate 4. The key technology is to install a movable telescopic rod 2 between the upper pressing plate 1 and the lower bottom plate 4, and to put a compression spring 3 on the movable telescopic rod 2 to form an elastic support system. A circular hole is opened in the middle of the upper pressing plate 1, and the aperture matches the welding gun. Two semicircular ceramic ring pressure rod limiting holes 5 are vertically opened on one side of the circular hole. The spacing of the limiting holes 5 matches the spacing of the ceramic ring pressure rod 7 on the welding gun. A hole 6 is opened in the middle of the lower bottom plate 4. The aperture of the hole 6 matches the ceramic ring, and the hole position matches the position of the stud clamp 9 at the end of the stud welding machine.
