Problems solved by technology

[0003] As far as the common technology is concerned, the ejector rod achieves the effect of elongation and shortening through the mutual cooperation between the rack and pinion and the worm gear. However, these transmission parts will increase the complexity of the structure, which will lead to an increase in manufacturing costs.

Embodiment Construction

[0029] Please see first Figure 1 to Figure 3 , The indexing chuck 10 of the present invention includes a clamp seat 20 , an indexing shaft 30 , and a positioning assembly 40 .

[0030] The clamp seat 20 has a seat body 21 and a cover body 22 covering the seat body 21. The center of the seat body 21 has an elongated groove 211. The cover body 22 has an opening 221. The opening 221 of the cover body 22 is correspondingly connected to the seat body. 21 of the elongated groove 211, so that both together form the workpiece accommodating groove 23. The seat body 21 has a first arc groove 213 communicating with the elongated groove 211 and a second arc groove 215 communicating with the elongated groove 211 on two opposite sides of the elongated groove 211, and the cover body 22 is Two opposite sides of the opening 221 respectively have a third arc groove 223 communicating with the opening 221 and a fourth arc groove 225 communicating with the opening 221, the first arc groove 213 o...

Abstract

The invention discloses an indexing chuck. The indexing chuck comprises a clamping seat, an indexing shaft, a piston and a locating shaft. The indexing shaft is rotatably arranged in the clamping seat. The piston is arranged in the clamping seat in a manner that the piston can transversely move in a reciprocating manner. The locating shaft is arranged in the clamping seat in a manner that the locating shaft can move in the axial direction of the locating shaft. The piston is provided with a first inclined guiding portion, and the locating shaft is provided with a second inclined guiding portion. The piston and the locating shaft are clamped together through the first inclined guiding portion and the second inclined guiding portion, and therefore, in the moving process of the piston, the locating shaft can be driven by the piston to move close or away relative to the indexing shaft; and furthermore, the effect that a workpiece is located or released is achieved. In this way, by means ofthe indexing chuck, the structure can be simplified so that the cost can be lowered; and when the indexing chuck is subjected to the action of centrifugal force, the jacking force, for the workpiece,of the locating shaft can be increased through cooperation between the first inclined guiding portion and the second inclined guiding portion.

Description

technical field [0001] The invention relates to a lathe chuck, in particular to an indexing chuck that can effectively simplify the structure. Background technique [0002] The so-called indexing chuck mainly uses a retractable ejector rod to hold the workpiece on the indexing shaft. After each process is completed, the indexing shaft is used to adjust the angle of the workpiece relative to the tool. After the angle adjustment is completed, the The next process can be carried out directly without recalibrating the position of the workpiece, thus solving the accuracy problem caused by repeated disassembly and assembly of the workpiece. [0003] As far as the common technology is concerned, the ejector rod achieves the effect of elongation and shortening through the mutual cooperation between the rack and pinion and the worm gear. However, these transmission parts will increase the complexity of the structure, which will lead to the increase of the manufacturing cost. Conten...
