Description
Technical Field
The invention belongs to the technical field of clamping devices, and particularly relates to a clamp for turning eccentric parts.
Background
In mechanical transmission, eccentric parts (fig. 3, 4) are indispensable. The turning motion is changed to a reciprocating rectilinear motion or vice versa, which is generally accomplished by using an eccentric part. For turning of eccentric parts, the eccentric clamp is usually used for realizing, whether the eccentric clamp is reasonably designed or not often determines whether the parts can be machined to be qualified or not and whether the machining size is stable or not. The eccentric clamp adopted in the traditional process is shown in fig. 5 and 6, the elastic openings are distributed in the parallel direction with the eccentricity of the eccentric part, and the eccentric distance is out of tolerance after the part is machined due to stress deformation of the clamp in the machining process, and meanwhile, the size of the turning excircle cannot be guaranteed, so that the machining effect of the eccentric part is seriously affected.
Disclosure of Invention
The invention aims to overcome the defects and provide the clamp for turning the eccentric parts, which has the advantages of simple structure, stability, reliability, convenience in operation and accuracy and feasibility.
The aim and the main technical problems are achieved by adopting the following technical scheme:
the invention relates to a clamp for turning eccentric parts, which comprises a clamp body, a fastening screw A and a fastening screw B, wherein: the front part of the clamp body is transversely provided with an elastic opening, the middle part of the elastic opening is provided with a mounting hole, a fastening screw A and a fastening screw B are respectively and penetratingly arranged in mounting blocks at two sides of the clamp body, a longitudinal mounting groove is formed between the mounting blocks at two ends, and the center line of the mounting groove penetrates through the center of the cross section of the mounting hole and is perpendicular to the central axis of the mounting hole.
The fixture for turning eccentric parts, wherein: and the fastening screw A and the fastening screw B are matched with locknuts, and the locknuts are attached to the outer side surfaces of the mounting blocks.
The fixture for turning eccentric parts, wherein: the mounting hole is a cylindrical through hole.
The fixture for turning eccentric parts, wherein: the mounting axes of the fastening screw a and the fastening screw B are on the same straight line.
Compared with the prior art, the invention has obvious advantages and beneficial effects. According to the technical scheme, in the clamp for turning the eccentric part, the front part of the clamp body is transversely provided with the elastic opening, the middle part of the elastic opening is provided with the mounting hole, the longitudinal mounting grooves are formed between the mounting blocks at the two sides of the clamp body, and the elastic opening is adjusted to be in the direction perpendicular to the eccentric distance of the eccentric part, so that the eccentric distance change caused by clamp deformation when the clamp is clamped on a lathe is avoided, and the stability of the eccentric distance of the part after turning is better ensured; the mounting blocks at two sides of the clamp body are respectively penetrated with the fastening screw A and the fastening screw B, and the fastening screws are used for fixing the parts during clamping, so that the loosening of the parts in the turning process is prevented, and the processed parts are more reliable and stable; and the fastening screw A and the fastening screw B are matched with each other and provided with locknuts, and the locknuts are attached to the outer side surfaces of the mounting blocks, so that the clamping stability is further ensured. In a word, the invention has the advantages of simple structure, stability, reliability, convenient operation, accuracy and feasibility, and is suitable for popularization and application of clamping of turning eccentric parts.
