Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the invention is further explained in the following with the accompanying drawings and the embodiments.

As shown in figure 1, the port plane polishing device for the multi-surface polishing type automobile exhaust manifold comprises a bottom plate 1 and two support frames 2 arranged at the left side and the right side of the bottom plate 1, wherein a rotary clamp used for clamping the exhaust manifold and driving the exhaust manifold to rotate is correspondingly arranged below the opposite inner sides of the two support frames 2. Through rotary fixture, exhaust manifold can carry out the multiaspect and polish under the circumstances of not being clamped repeatedly, has saved the time of the clamping of making a round trip on the one hand, and on the other hand has also saved the process of relocating behind the exhaust manifold clamping at every turn, has guaranteed the effect uniformity after exhaust manifold polishes. Horizontal diaphragm 3 of placing about being equipped with above the relative inboard of two support frames 2, be equipped with on diaphragm 3 and be used for polishing the planar grinding machanism of exhaust manifold port, be equipped with on two support frames 2 and order about diaphragm 3 vertical removal in order to adjust the adjustment mechanism of grinding machanism height. Through the adjusting mechanism, the polishing mechanism can be adjusted in a self-adaptive mode according to different heights of different types of exhaust manifolds, and meanwhile, when the exhaust manifolds are turned over, the polishing mechanism can move upwards to avoid.

Specifically, the rotary clamp comprises two rotary U-shaped clamping hands 4 which are correspondingly arranged on the opposite inner side walls of the two support frames 2 from left to right, the two U-shaped clamping hands 4 are horizontally arranged, and the U-shaped openings face to face; two arc-shaped clamping blocks 5 are symmetrically distributed in each U-shaped clamping hand 4 from top to bottom, each arc-shaped clamping block 5 is connected with a locking member, each locking member comprises a locking rod 7 which is connected with the arc-shaped clamping block 5 and vertically penetrates through the U-shaped clamping hand 4, and a locking nut 8 which is arranged on the locking rod 7 and is attached to the end face of the U-shaped clamping hand 4, and the arc-shaped clamping blocks 5 are used for clamping and fixing the exhaust manifold. Wherein the right rotating U-shaped tong 4 is connected with a rotating handle 6; the U-shaped clamp 4 is driven to rotate by rotating the handle 6, so that the exhaust manifold is turned over.

Polishing mechanism is including setting up at 3 left sides of diaphragm department cylinder 9, the sliding seat 10 of sliding of adorning in 3 middle parts of diaphragm and being connected with cylinder 9, the middle part of diaphragm 3 is equipped with direction draw-in groove 3a along left right direction, sliding seat 10 is installing in direction draw-in groove 3a, improves the direction when for sliding seat 10 slides. And a polishing block 11 for polishing the port plane of the exhaust manifold is arranged at the bottom of the sliding seat 10.
