Automatic transferring device for numerically controlled lathe

Abstract

The invention discloses an automatic transferring device for a numerically controlled lathe. The automatic transferring device comprises an X-directional supporting arm and a Z-directional supportingarm, and the X-directional supporting arm and the Z-directional supporting arm are arranged on a numerically controlled lathe body. A servo motor I is connected with a gear I and arranged on a slide seat which is slidably and horizontally arranged on the X-directional supporting arm. The Z-directional supporting arm vertically slides up and down on the Z-directional supporting arm, a workpiece clamp is arranged at the bottom of the Z-directional supporting arm, and a vertical rack meshed with the gear I is arranged on the lateral side of the Z-directional supporting arm. Gears are driven to rotate by a pair of servo motors to further drive the Z-directional supporting arm with racks to accurately move along the X direction and the Z direction, a workpiece clamp at the bottom of the Z-directional supporting arm automatically completes grabbing and feeding actions, high precision is achieved, machining speed is increased, and machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of devices specially suitable for workpiece conveying, feeding, adjustment, reversing, clamping or unloading of automatic or semi-automatic lathes, and in particular relates to an automatic lathe installed on a numerically controlled lathe for processing small workpieces. Transfer device. Background technique [0002] With the improvement of the processing pace of machine tools and the increase of labor costs, more and more enterprises require machine tools to achieve fully automated or semi-automated production; loading and unloading is one of the necessary links in workpiece processing. There are currently three ways of loading and unloading: [0003] The first type: Manual loading and unloading: In the past, when CNC lathes processed long shaft parts, manual loading and unloading was required; during operation, the worker stepped on the chuck foot switch, took the workpiece with one hand, and pressed the ...

Problems solved by technology

[0003] The first type: Manual loading and unloading: In the past, when CNC lathes processed long shaft parts, manual loading and unloading was required; during operation, the worker stepped on the chuck foot switch, took the workpiece with one hand, and pressed the tailstock movement button with the other hand, and the tailstock sleeve The top slowly tightens the workpiece, and at the same time, the soles of the workers need to constantly step on the foot switch; but the manual loading and unloading operation is cumbersome, requiring the tacit cooperation between man and machine, and the efficiency is low. Moreover, the labor intensity of the workers is high, and the processing cycle is affected by the proficiency of the operator. The impact is great, coupled with the increase in labor costs, this way of loading and unloading is gradually decreasing

[0004] The second type: loading and unloading of the support frame: At present, CNC lathes generally use the support frame for loading and unloading; the left end of the support frame is fixed on the spindle box, and the position is adjusted up and down by a V-shaped block, which cannot move axially; The right end is fixed on the tailstock, and the position can be adjusted up and down through another V-shaped block but cannot move axially; this kind of support frame has a simple structure and is more convenient to operate, and is suitable for hydraulic tailstock; due to the limitation of the support frame structure, its rigidity Poor, it will sag after a period of use, and needs to be readjusted, and the axial direction is usually not adjustable, and the V-shaped block is prone to rotation during the radial adjustment process, with low adaptability and reliability. Driven tailstock, due to structural limitations, this kind of carrier is not suitable

[0005] The third method: fully automated loading and unloading: the machine tools are connected into an automatic line, and the truss manipulator is used for loading and unloading; the advantages of this loading and unloading method are obvious. It adopts fully mechanized production, with fast processing time and high efficiency, especially suitable for large quantities of a single type of workpiece Production; the shortcomings of fully automated loading and unloading are also prominent. Most of a set of automatic lines require more than two hosts, plus silos, trusses, manipulators, special fixtures, etc., all of which are expensive, and many small companies cannot afford them. It occupies a large area and is difficult to debug. When changing parts types, the entire production line needs to be adjusted systematically. Therefore, the advantages of fully automated loading and unloading are not obvious in the occasion of multi-variety and small-batch processing.
