Problems solved by technology
[0002] In the existing technology, it is often necessary to clamp and position the workpiece, but there are problems in the clamping mechanism, which cannot meet the requirements of clamping and precise positioning at the same time. During the processing of the flange workpiece, the center of the flange spline and the flange The concentricity requirements of the sealing surface are extremely high, and the positioning accuracy of the traditional clamping mechanism for the flange is not enough, resulting in low machining accuracy of the workpiece

The invention discloses a clamping and locating mechanism for a flange. The clamping and locating mechanism comprises a clamp and a clamping plate, wherein the clamp consists of a flange locating shaft and a pull rod, wherein the flange locating shaft is connected with a base through a bolt, and the pull rod penetrates through the center of the flange locating shaft. The clamping and locating mechanism is characterized in that the pull rod is flexible, a lock head is arranged at the head of the pull rod, a lock hole is formed in the center of the clamping plate, and the lock hole is matched with the lock head. The clamping and locating mechanism for the flange provided by the invention has the following beneficial effects that the flange is located by the combined action of the pull rod and the flange locating shaft, the flange is clamped by the pull rod and the clamping plate, and the flange is precisely located while clamping is ensured, so that the flange processing precision is improved and the accuracy is within 0.03mm.
Description
technical field [0001] The invention relates to a clamping and positioning mechanism for flanges, in particular to a clamping mechanism for precise positioning during flange processing. Background technique [0002] In the existing technology, it is often necessary to clamp and position the workpiece, but there are problems in the clamping mechanism, which cannot meet the requirements of clamping and precise positioning at the same time. During the processing of the flange workpiece, the center of the flange spline and the flange The concentricity of the sealing surface is extremely high, and the positioning accuracy of the traditional clamping mechanism for the flange is not enough, resulting in low machining accuracy of the workpiece. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art, and to provide a clamping and positioning mechanism for clamping flange workpieces and performing precise positioning and...
