In the prior art, the welding reject ratio is higher when the welding end of the cold end assembly welding tool bites the silencing bag, so that the productivity is reduced and the rejection rate is increased. The reason is that the positioning mode of the weld joint of the silencing bag is not accurate.
The end biting edges can not be consistent and stable relative to the position of the pipe orifice welding seam due to the technical problem of the end biting noise elimination bag, and the tool welding seam positioning scheme is to weld the pipe orifice welding seam by end biting edge positioning, so that the welding reject ratio is extremely high.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the technical scheme provided by the utility model is to provide a positioning mechanism for a welding port of an end-biting silencing bag, and solve the problem that the welding reject ratio is high when the welding end of the existing welding tool bites the silencing bag.
In order to solve the problems, the technical scheme includes that the end-biting silencing bag welding port positioning mechanism comprises a base, an upper positioning mechanism, a lower positioning mechanism and a side positioning mechanism, wherein the side positioning mechanism comprises a sliding block connected with the base in a sliding mode, a first driving rod arranged along the horizontal direction is fixedly connected to the side of the base, one end of the first driving rod is detachably connected with the sliding block, and the side face of the sliding block abuts against the end face of the silencing bag.
The beneficial effect that this scheme produced is: the end face of the silencing bag is limited by the side limiting mechanism, so that the end face of the silencing bag keeps consistent with the position of the pipe orifice welding line, the stability of clamping and fixing is improved, the welding reject ratio of the pipe orifice welding line is effectively reduced, and the production capacity of products is improved.
Furthermore, the sliding block comprises a hook-shaped limiting block and a moving block, the moving block is connected with the base in a sliding mode, the limiting block is fixedly connected with the moving block, and the limiting block abuts against the end face of the silencing bag. Through setting up hook-like stopper for the terminal surface of stopper one end is crossed the end of noise elimination package and is stinged the arris and be wrapped the terminal surface contact with the noise elimination, thereby realizes better spacing effect, improves clamping stability, and the production and processing of being convenient for is promoted.
Further, stop gear includes briquetting, lower briquetting from top to bottom, briquetting and base fixed connection down, and the base lateral wall is fixed with the type of falling L bracing piece along vertical direction, and the bracing piece is located the one end fixedly connected with second actuating lever of base top, and the drive can be dismantled with last briquetting and be connected. Carry out spacing once through last briquetting and briquetting down to the noise elimination package, the side stop gear of being convenient for carries out the secondary spacing, improves clamping efficiency.
Furthermore, the end surfaces of the upper pressing block and the lower pressing block, which are contacted with the silencing bag, are arc end surfaces. The arc-shaped end face is attached to the arc-shaped side face of the silencing bag, so that the clamping limiting effect is improved.
Furthermore, an air groove with an opening at the upper end is formed in the lower pressing block, and the side surface of the air groove is communicated with an air exhaust device. After the upper pressing block and the lower pressing block fix and limit the silencing bag, the air extractor is opened to extract air in the air groove to form negative pressure in the air groove, so that the silencing bag is adsorbed to increase the pressure of the silencing bag on the lower pressing block, the friction force is improved, the sliding probability of the silencing bag relative to the lower pressing block is reduced, and the clamping stability of the device is improved; the deformation of the silencing bag caused by the overlarge pressurization of the upper pressing block for the fixed silencing bag is avoided.
Furthermore, soft rubber pads are bonded on the arc-shaped end faces of the upper pressing block and the lower pressing block. The soft rubber pad is bonded to avoid the upper pressing block and the lower pressing block from scratching the silencing bag.
