Embodiment Construction

[0023] Combine below Figure 1-Figure 6 The present invention is described in detail, and for convenience of description, the orientations mentioned below are now stipulated as follows: figure 1 The up, down, left, right, front and back directions of the projection relationship itself are the same.

[0024] The invention relates to a fastening device for assisting in tightening a three-jaw chuck on a lathe, which is mainly used in the process of mechanically tightening a three-jaw chuck to fix a workpiece. The invention will be further described below in conjunction with the drawings of the invention:

[0025] A fastening device for assisting in tightening a three-jaw chuck on a lathe according to the present invention includes a right-angle hanging plate 11 with bolt holes, and a cylinder 13 is embedded in the horizontal end surface of the right-angle hanging plate 11, and the cylinder The lower end of 13 is power-connected with the lifting rod 14, the lower end of the lifti...

Abstract

The invention discloses a fastening device for assisting in tightening a three-jaw chuck on a lathe. The fastening device comprises a right-angle hanging plate with a bolt hole, wherein an air cylinder is embedded in the horizontal end surface of the right-angle hanging plate; the lower end of the air cylinder is in power connection with a lifting rod; an arc-shaped track is arranged at the lowerend of the lifting rod; and a swinging assembly is arranged in the arc-shaped track. According to the fastening device disclosed by the invention, a plurality of groups of limiting rods which are clamped on double surfaces and are arrayed along the three-jaw chuck in an annular manner are utilized, and the limiting rods can be movably separated from abutting against an extension rod of the three-jaw chuck, so that synchronous rotation or disconnection transmission of the three-jaw chuck is controlled; the position change of oil liquid difference in a sealed pipeline is changed, so that the limiting capacity of rotation of a double-surface clamping structure part is realized, and the ordered working steps of the clamping structure part clamping-sliding out-releasing-sliding back along a circular rail are realized; and the whole process can be controlled by a program, and manual intervention is not needed, so that the problem that a workpiece is not completely fixed due to insufficient force is avoided, and the probability that workers are accidentally injured by a cutter is reduced.

Description

technical field [0001] The invention relates to the technical field of machine tool parts, in particular to a fastening device for assisting in fastening a three-jaw chuck on a lathe. Background technique [0002] When the lathe is working, it is necessary to use a three-jaw chuck to clamp and fix one end of the workpiece. For the safety of the tooling process, the three-jaw chuck needs to clamp and fix the workpiece stably to prevent the workpiece from falling off under high-speed rotation and cause safety. Hidden danger. [0003] However, in the process of loading and unloading on a traditional lathe, the method of manually rotating the three-jaw chuck is usually used. However, this method is firstly limited by the amount of force that can be applied manually, and secondly, the hand enters the lathe, which will increase the probability of the tool accidentally injuring the operator. The present invention illustrates a device capable of solving the above-mentioned problem...
