Description

Technical Field

[0001] The invention relates to the technical field of a wire cutting machine deviation correction mechanism, and in particular to a wire arrangement deviation correction mechanism. Background Art

[0002] The processing method of stone multi-wire cutting machine has greatly improved the efficiency of stone processing. Compared with the traditional gang saw cutting method, multi-wire cutting can complete more cutting tasks in the same time, greatly shortening the production cycle. In addition, the continuity and automation of stone multi-wire cutting machine are also high, which further improves production efficiency.

[0003] However, during the working process, it was found that the spacing of the wire arrangement was unstable, and there would be deviation or unevenness. The uneven arrangement or deviation of the wires and the axial angle deviation caused by the constant change in the outer diameter of the winding during the cutting process led to the reduction of accuracy and efficiency.

[0004] At the same time, after the cable has been used for a period of time, it needs to be cut and replaced. Generally, it is cut manually. Manual cutting requires cutting multiple cables after winding for multiple times, which is also time-consuming. Summary of the invention

[0005] The present invention proposes a wire arrangement correction mechanism, which ensures the uniformity of the wire arrangement and the constancy of the force, reduces the possibility of wire breakage, eliminates the wire saw phenomenon on the product, ensures the cutting effect, and greatly improves the quality of the cut product. At the same time, the mechanism can be used to automatically cut off a single wire arrangement at the initial section of the winding, and the diamond wire can be completely removed by the automatic rotation of the cutting machine.

[0006] To this end, the present invention provides a wire arrangement and correction mechanism, including a linear guide rail, a traveling mechanism is provided on the linear guide rail, a driving mechanism for driving the traveling mechanism to move is provided at one end of the linear guide rail, and a correction mechanism and a guiding shearing structure are provided on the traveling mechanism.

[0007] By adopting the above technical solution: the pulling force generated by the diamond wire is automatically adjusted, and the tension and direction can be automatically balanced when the wire is reeled in and out, and the reel is always kept tangent to the reel and reeled in vertically; the correction mechanism can move left and right under the drive of the driving mechanism to adapt to the axial position of the diamond wire on the bobbin, and at the same time, the correction mechanism automatically adjusts the inclination angle according to the external diameter of the bobbin, so that the diamond wire and the bobbin always maintain a tangent state, and the guided shearing structure can further limit and guide the diamond wire, and secondly, it is convenient to cut and replace the diamond wire.

[0008] Optionally, the linear guide rail includes a first guide rail and a second guide rail, the first guide rail and the second guide rail are arranged in parallel, and a mounting seat is provided at one end of the first guide rail and the second guide rail, and a driving mechanism is fixed on the mounting seat.

[0009] By adopting the above technical solution: the linear guide composed of the first guide rail and the second guide rail has higher stability, so that the position correction of the diamond wire is more accurate.

[0010] Optionally, the walking mechanism includes a walking block slidably arranged between a first guide rail and a second guide rail, the first guide rail and the second guide rail are provided with limiting grooves, and upper and lower sides of the walking block are provided with sliding convex strips that cooperate with the limiting grooves.

[0011] Optionally, the driving mechanism includes a driving motor disposed on a mounting seat, an output shaft of the driving motor is connected to a transmission screw, and the transmission screw is threadedly connected to a walking block.

[0012] By adopting the above technical solution: when deviation occurs, the drive motor rotates to drive the output shaft to rotate, the output shaft drives the transmission screw to rotate, and the transmission screw drives the walking block to slide on the first guide rail and the second guide rail to achieve axial deviation correction of the diamond wire.

[0013] Optionally, a mounting plate is fixedly mounted on the walking block, the correction mechanism is arranged at the end of the mounting plate, and the guiding shearing structure is arranged at the upper part of the mounting plate and between the first guide rail or the second guide rail.

[0014] Optionally, the correction mechanism includes a support seat installed at the end of the mounting plate, a rotating shaft is rotatably connected to the support seat, a mounting frame is fixed to the rotating shaft, and a correction component is installed on the mounting frame.

[0015] Optionally, the correction assembly includes a wire wheel rotatably connected to a mounting frame, and two counterweights are provided on the mounting frame below the wire wheel. The two counterweights and the wire wheel are located on one side of the mounting frame, and a gap is provided between the two counterweights for the diamond wire to pass through, and detectors are provided on the sides of the two counterweights.

[0016] By adopting the above technical solution: the diamond wire is passed through the gap between the two counterweight blocks and wrapped around the wire pulley. Under normal circumstances, the diamond wire is in the middle of the gap. When an offset occurs, the detector senses the signal and transmits it to the control and display system. The control and display system drives the drive motor to complete the left and right deviation correction. As the wire is continuously routed, the outer diameter of the wire drum will increase. Through the design of the counterweight block and the tension of the diamond wire itself, the rotating shaft can be rotated, thereby changing the inclination angle of the mounting frame, so that the diamond wire is tangent to the outer diameter of the wire drum. Of course, the center point of the wire pulley of the present invention is on the axis of the rotating shaft.

[0017] Optionally, a V-shaped groove is provided on the outer peripheral side of the guide wheel.

[0022] The shearing assembly includes a shearing blade disposed on the first guide rail or the second guide rail, and the shearing blade faces the opening of the U-shaped groove;

[0023] It also includes a control display system that is communicatively connected to the detector, and the control display system is driven and connected to the drive motor.

[0024] By adopting the above technical solution: the diamond wire is placed in the U-shaped groove and is further limited. Under normal circumstances, the walking block will not move to the shear blade. When the diamond wire needs to be cut, the travel of the walking block increases under the drive of the driving motor. When it reaches the shear blade, the shear blade can push open the elastic plate and enter the U-shaped groove. The diamond wire can be cut under the cooperation of the shear blade and the U-shaped groove.

[0025] The working principle and beneficial effects of the present invention are:

[0026] 1. Automatically adjust the tension generated by the diamond wire, automatically balance the tension and direction when reeling in and out, and always keep it tangential to the reel and reeling in vertical direction; driven by the driving mechanism, the correction mechanism can move left and right to adapt to the axial position of the diamond wire on the bobbin, and at the same time, the correction mechanism automatically adjusts the inclination angle according to the outer diameter of the bobbin, so that the diamond wire and the bobbin always maintain a tangent state. The guided shearing structure can further limit and guide the diamond wire, and it is convenient to cut and replace the diamond wire.

[0027] 2. The diamond wire is passed through the gap between the two counterweights and wound around the wire pulley. Under normal circumstances, the diamond wire is in the middle of the gap. When an offset occurs, the detector senses a signal and transmits it to the control and display system. The control and display system drives the drive motor to complete the left and right deviation correction. As the wire is continuously routed, the outer diameter of the wire drum will increase. Through the design of the counterweight and the tension of the diamond wire itself, the rotating shaft can be rotated, thereby changing the inclination angle of the mounting frame so that the diamond wire is tangent to the outer diameter of the wire drum. Of course, the center point of the wire pulley of the present invention is on the axis of the rotating shaft.

[0028] 3. The diamond wire is in the U-shaped groove, and is further limited. Under normal circumstances, the walking block will not move to the shear blade. When the diamond wire needs to be cut, the travel of the walking block increases under the drive of the driving motor. When it reaches the shear blade, the shear blade can push open the elastic plate and enter the U-shaped groove. The diamond wire can be cut with the cooperation of the shear blade and the U-shaped groove. BRIEF DESCRIPTION OF THE DRAWINGS
