Problems solved by technology

The positioning of the electrode wire generally uses a guide wheel. The speed of the electrode wire is fast during work, and the rotation speed of the wire transporting guide wheel is high. Under high-load work, the position of the guide wheel is easy to shift, resulting in the electrode wire jumping or even breaking during the cutting process. reduce the quality of the product

Embodiment 1

[0018] Such as figure 1 and figure 2 As shown, the guide wheel adjustment mechanism includes a guide wheel 1, a screw rod 7, a bearing sleeve 12, a bearing cover 11, a screw bearing seat 9, a guide wheel bearing seat 17 and a knob 6, and the screw rod 7 is connected to the screw bearing seat respectively. 9. The bearing cover 11 and the bearing sleeve 12 are connected in series as one. The screw bearing seat 9, the bearing cover 11 and the bearing sleeve 12 can rotate around the screw 7. The outer side of the bearing sleeve 12 is fixed with an eccentric bushing 2 One end of the bearing sleeve 12 is provided with a threaded hole to match with one end of the screw 7, the other end of the screw 7 is equipped with a knob 6, and a guide is installed in the cavity of the other end of the bearing sleeve 12. The wheel bearing seat 17, the bearing A16 is installed in the guide wheel bearing seat 17, the bearing A16 is arranged on the shaft of the guide wheel 1, and the eccentric bush...

Embodiment 2

[0028] Assemble the adjustment mechanism of the guide wheel 1, install the adjustment mechanism of the guide wheel 1 on the cantilever of the wire cutting machine tool, and fix it with the top screw. The fixedly connected eccentric bush 2 rotates, and the depth of the groove 3 of the eccentric bush 2 is regularly distributed, so as to adjust the position of the guide wheel 1 in the Z-axis direction, and then turn the knob 6, and the screw 7 drives the bearing sleeve through the threaded hole The cylinder 12 moves to adjust the X-axis direction of the guide wheel 1, thereby changing the position of the electrode wire.

[0029] Along with the wearing and tearing of guide wheel 1, processing accuracy declines, can twist jackscrew, the adjustment mechanism of guide wheel 1 is moved out, replaces with new one, is convenient to disassemble, and does not affect working efficiency.

Abstract

The invention relates to the field of machine tools, in particular to a guide wheel adjusting mechanism. The guide wheel adjusting mechanism comprises a guide wheel, a screw, a bearing sleeve, a screw bearing block, a guide wheel bearing block and a knob, wherein one end of the screw is positioned in the knob; and the other end of the screw successively penetrates through the screw bearing block, a bearing cap and the bearing sleeve and then is connected with a plug. The knob drives the screw to adjust the guide wheel in the X-axis direction, an eccentric bush is twisted to adjust the guide wheel in the Z-axis direction, and a wire electrode is constant at a relative spatial position. Totally, the guide wheel adjusting mechanism has the advantages of novel design, capability of adjusting the position of the guide wheel, simplicity in operation, convenience in assembling and the like, can meet requirements of markets, and is suitable for being popularized on a large scale.

Description

technical field [0001] The invention relates to the field of machine tools, and in particular to a guide wheel adjustment mechanism. Background technique [0002] The electric spark cutting machine relies on applying a high-frequency pulse power supply between the workpiece and the electrode wire, and cutting under the condition of cooling medium. The positioning of the electrode wire generally uses a guide wheel. The speed of the electrode wire is fast during work, and the rotation speed of the wire transporting guide wheel is high. Under high-load work, the position of the guide wheel is easy to shift, resulting in the electrode wire jumping or even breaking during the cutting process. Reduce the quality of the product. EDM machine tools have high requirements on the constant position of the electrode wire in space. For this, our company has developed a guide wheel adjustment mechanism based on years of research experience. The guide wheel can be driven by the knob to adj...
