Clamp for multi-station straight pipe manifold edge opening machining

Abstract

The invention relates to the field of manifold machining tools, and discloses a clamp for multi-station straight pipe manifold edge opening machining. The clamp comprises a fixed base. The middle position of the fixed base is provided with a cavity. A special-shaped cam is arranged in a horizontal direction inside the cavity. The outer side of the special-shaped cam makes in contact with a plurality of guide balls. Guide columns are arranged on the outer sides of the guide balls and penetrate through the interior of the fixed base. The other ends of the guide columns are located in a pluralityof fixing holes formed in the outer side edge of the fixed base. Clamping rings are arranged on the end portions of the guide columns located in the fixing holes. Buffer springs sleeve the guide columns located in the fixing holes. Adjusting lead screws are arranged in the middles of the outer sides of the fixing holes. Sliding blocks are rotatably arranged at one ends of the inner sides of the adjusting lead screws, adjusting rings are fixedly arranged at the other ends of the sliding blocks, and a rotating shaft is arranged in the middle of the special-shaped cam. According to the clamp, the vertical fixing of the manifold is realized, later edge opening machining requirements are facilitated; and meanwhile, the adjusting lead screws and the adjusting rings are arranged, and fixing requirements of manifolds with different diameters are met.

Description

technical field [0001] The invention relates to the field of tooling for processing water distributors, in particular to a fixture for edge processing of multi-station straight pipe water distributors. Background technique [0002] Manifold is a water distribution and collection device used to connect various heating pipes for water supply and return in the water system. The water separator used in the floor heating and air conditioning system should be made of brass, and the water separator used in the renovation of the household surface of the tap water supply system is mostly made of PP or PE. Both supply and return water are equipped with exhaust valves, and many water separators are also equipped with drain valves for supply and return water. The front end of the water supply should be equipped with a "Y" type filter. Valves should be installed in each branch of the water supply pipe to adjust the water volume. [0003] At present, the common processing methods for t...

Chinese patent (notification number: CN202114118U) discloses a processing device along the edge of a straight pipe water distributor, including a clamping part, a positioning module, and a hemispherical pull block; the clamping part is used to clamp the pipe fittings, including symmetrically arranged The left clamping block and the right clamping block, after the left and right clamping blocks are closed, there is a gap in the upper part that allows the hemispherical pulling block to pass through; the positioning module is a semi-cylindrical body, and the upper part of the positioning module is provided with a positioning locking mechanism. The positioning and locking mechanism includes symmetrically arranged balls, springs and fastening screws that are sequentially connected from the inside to the outside; the hemispherical pull block includes a hemisphere, and the lower side of the hemispherical body is provided with a positioning lock that can be buckled with the positioning and locking mechanism. The left and right sides of the positioning body are provided with pits that cooperate with the balls, and the upper part of the hemisphere is connected with the drawstring fixing device. Although this device can ensure the effective fixing of the edge of the water distributor to a certain extent, in actual operation Among them, only a single water separator can be fixed each time, and the workpiece needs to be replaced continuously when processing the edge, and the processing efficiency is very low. Therefore, further improvement is needed
