summary of the invention
The invention is intended to the circumference soldering grip device that a kind of silencer for automobile is provided, can 360 ° of rotations when producing or keep in repair to meet silencer for automobile.
For solving above-mentioned purpose, there is provided following base case: silencer for automobile circumference soldering grip device comprises clamp base, two pieces of back-up blocks, two pieces of grip blocks, extension spring, two supporting rollerns, described two pieces of back-up blocks are fixedly mounted in clamp base, described two pieces of grip block bottoms are movably hinged with two pieces of back-up blocks respectively, the centre of gyration of described two support rollers is hinged with the top movable of two pieces of grip blocks respectively, and described extension spring is arranged between two pieces of grip blocks.
Adopt technique scheme, when silencer is placed on this device, effect due to gravity has downward displacement, and the force of rolling friction produced by gravity drives two support rollers to rotate, silencer produces downward displacement, and the angle that two pieces of grip blocks are formed increases, the length of extension spring increases.Now, the elastic force of extension spring constantly increases along with the change of length, when the loss of the extension spring elastic force increased, the gravity of silencer and various structural friction is common making a concerted effort of being formed is zero, silencer produces displacement no longer downwards and is accommodated by the novel device provided of this enforcement.Because supporting rollern can rotate, only need apply very little power to silencer and just can meet silencer 360 ° rotation.This apparatus structure is simple, be easy to operation, meets the requirement that silencer 360 ° rotates.
Preferred version one: as the further optimization to base case; the outer peripheral face of supporting rollern is provided with flexible material periphery cover, and rubber periphery tackling is flexible, after contacting with silencer outer peripheral face; be conducive to protect silencer outer peripheral face, less to the damage of silencer outer peripheral face.
