Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0024] The inventor found through research that the adjustment of the clamping block is difficult, mainly because the position of the clamping block cannot be adjusted after the clamping block is fixed on the clamping piece. The tail end of the product to be clamped will shake a lot because the length of the clamping block of the clamp is short and the clamping position is too close to the end of the product to be clamped.

The invention discloses a three-jaw chuck clamp suitable for longitudinal lengthening equipment. The three-jaw chuck clamp comprises a clamp pedestal, a clamping block fixing part and a clamp clamping block; one end of the clamp pedestal is provided with a connecting hole for connecting the three-claw clamp with the clamp pedestal; a clamp limiting slot is formed below the clamp pedestal; the other end of the clamp pedestal is equipped with the clamping block fixing part; the bottom of the clamping block fixing part is arranged on the upper surface of the clamp pedestal; the top of the clamping block fixing part extends out in the longitudinal direction from the upper surface of the clamp pedestal; a groove is formed in the clamping block fixing part; one end of the clamp clamping block is embedded into the groove, and the other end of the clamp clamping block extends out; a clamping block regulating threaded hole is formed in one surface, opposite to an embedding direction of the clamp clamping block, of the clamping block fixing part; a clamping block fixing plate is arranged on one surface, parallel to the embedding direction of the clamp clamping block, of the clamping block fixing part; and a clamping block fixing bolt is arranged on the clamping block fixing plate. With the adoption of the three-claw chuck clamp disclosed by the invention, a clamping angle of a clamped product can be conveniently adjusted.
Description
technical field [0001] The invention relates to the field of machining equipment, in particular to a three-jaw chuck fixture suitable for longitudinal equipment. Background technique [0002] Longitudinal equipment refers to equipment with a longitudinally extending structure, such as the longitudinal extension of an optical fiber preform. [0003] In the prior art, a three-jaw chuck fixture is usually used to clamp the longitudinal equipment, and then the longitudinal equipment is processed. figure 1 It is a structural schematic diagram of a three-jaw chuck fixture in the prior art. Such as figure 1 As shown, the clamp includes a clamp block 1 , a clamp block fixing piece 2 , a clamp block fixing screw 3 , a connecting hole 4 between the clamp and the chuck, a clamp limit groove 5 , and a clamp block fixing screw hole 6 . figure 2 It is a schematic diagram of the assembly of the three-jaw chuck fixture and the three-jaw chuck in the prior art. Such as figure 2 As sho...
