Embodiment Construction
[0024] The present invention is described in detail with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following examples.
[0025] An internally expanding elastic clamp, the elastic clamp includes a clamp body 1 and a tensioner 2, one end of the clamp body is formed as a clamping part 11 for clamping on a machine tool, and the other end is formed as a clamping part 11 for inserting into the inner hole 31 of a product 3 to be processed. An insertion part 13, and the shape of the outer side of the insertion part matches the shape of the side surface of the inner hole of the product to be processed; a hollow part 12 for processing the end face 32 of the inner hole of the product to be processed is formed between the clamping part and the insertion part, And the sectional radius of the space-avoiding part is smaller than the sectional radii of the clamping part and the insertion part respectively; a cavity 14 is for...

The invention discloses an internal expansion type elastic clamp which comprises a clamp body and a tensioner, wherein one end of the clamp body forms a clamping part, and the other end thereof forms an insert part with an outer side surface shape matched with the shape of an inner side of an inner hole of a product to be processed; a vacancy avoiding part is formed between the clamping part and the insert part and has a cross section radius smaller than that of the clamping part and the insert part; a cavity is formed in the center of the other end of the clamp body, namely the insert part, along the axis; the opening of the cavity is positioned at the end surface of the insert part; one end of the tensioner is internally meshed with the cavity of the insert part through a thread; a plurality of tension grooves are formed in the outer side surface of the insert part of the clamp body along the axis direction, and the bottom parts, are communicated with the cavity; the other end of the tensioner can be accommodated in the inner hole of the product to be processed. The elastic clamp is simple in structure, and realizes processing of two ends of the product in one-time clamping, as a result, the processing size and position are ensured, and the product quality is promoted.
Description
technical field [0001] The invention relates to an internal expansion type elastic clamp. Background technique [0002] At present, the processing of the two end faces of products with inner holes requires two clamping and positioning, and then processing separately, which is not only inefficient, but also difficult to ensure the position of the product, which affects the processing quality of the product. Contents of the invention [0003] In order to overcome the above defects, the present invention provides an internally expanding elastic clamp, which not only has a simple structure, but also can realize the processing of both ends of the product in one clamping, so as to ensure the processing size and position and improve product quality. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: an internally expanding elastic clamp, the elastic clamp includes a clamp body and a tensioner, one end of the clamp body for...
