Description

Technical Field

[0001] The utility model relates to the technical field of fast-moving wire cutting machines, in particular to a wire fastening mechanism for fast-moving wire cutting machines. Background Art

[0002] Fast wire cutting machines are widely used in modern industrial parts manufacturing industry for precision cutting of workpieces. During the processing, the current is connected and the high temperature generated by ionization causes the surface of the workpiece to melt or even vaporize, thereby forming pits on the surface of the workpiece. Since the processing is continuous, a gap is gradually cut into the workpiece.

[0003] After searching: Patent No. CN218874022U is a wire fastening device for a high-speed wire cutting machine, which relates to the field of high-speed wire cutting machines. The wire fastening device for a high-speed wire cutting machine includes a wire storage drum, which is rotatably mounted on a workbench of the high-speed wire cutting machine; and a first screw rod, which is mounted on the outer wall of the wire storage drum.

[0004] However, the wire fastening device for the high-speed wire cutting machine mentioned above still has some shortcomings. Although the second screw rod can be adjusted circumferentially with the wire storage drum as the axis, it is known that in the actual process of winding the wire, when the wire is wound to the end, the end of the wire is not necessarily exactly located at the second screw rod. There may be a certain distance between the end of the wire and the second screw rod, which makes it impossible to effectively wind the end of the wire around and fix it on the second screw rod, reducing the effect of use. Therefore, we propose a wire fastening mechanism for high-speed wire cutting machine to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a wire tightening mechanism for a fast-moving wire cutting machine, which can not only adjust the axial position of the second screw rod with the wire drum as the axis, but also adjust the lateral position of the second screw rod, so that the ends of the wires at different positions can be effectively wound and fixed on the second screw rod, and then the wires can be effectively tightened on the wire drum, thereby improving the use effect of the device.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: it includes a high-speed wire cutting machine body and a second screw rod, one side of the high-speed wire cutting machine body is fixedly connected with a driving motor, the output shaft of the driving motor is fixedly connected with a rotating shaft, the outer side of the rotating shaft is fixedly sleeved with two baffles, the same wire reel is fixedly connected between the two baffles, the outer side of the wire reel is fixedly connected with a first screw rod, the outer side of the baffle on the right side is provided with an annular groove, the annular groove is slidably sleeved on a slide seat, the top of the slide seat is fixedly connected with a cross plate, an axial adjustment and fixing mechanism is provided between the slide seat, the cross plate and the annular groove, and a lateral adjustment mechanism is provided between the cross plate and the second screw rod.

[0007] The utility model is further configured as follows: a plurality of locking grooves are provided on the inner wall of the annular groove; the axial adjustment fixing mechanism comprises a lower spring fixedly connected to the inner wall of the top of the slide seat; the bottom end of the lower spring is fixedly connected to a lifting plate; the bottom of the lifting plate is fixedly connected to a locking rod; the locking rod is movably clamped in the corresponding locking groove; and the top of the lifting plate is fixedly connected to a connecting rod.

[0008] By adopting the above technical scheme, according to the axial position of the end of the wire, the connecting rod, the lifting plate and the locking rod are pulled upward by the pull ring. At this time, the lower spring is compressed, and the locking rod moves up to disengage from the locking groove without fixing the slide. At this time, the slide can be slid and adjusted along the annular groove, and then the axial position of the second screw rod can be adjusted, so that the end of the wire can be wound and fixed on the outside of the second screw rod, and then the wire can be fastened to the outside of the wire drum to prevent the wire from loosening and falling off. After the adjustment, the pull ring and the connecting rod are released. At this time, under the elastic force of the lower spring, the locking rod moves down and is clamped in the locking groove, and then the slide and the cross plate can be fixed.

[0009] The utility model is further configured as follows: the top end of the connecting rod extends to the top of the horizontal plate and is fixedly connected with a pull ring, the lower spring is sleeved on the outside of the connecting rod, and the lifting plate is slidably sleeved in the sliding seat.

[0010] By adopting the above technical solution, it is convenient to pull the connecting rod, and at the same time it is beneficial to guide the lower spring and the lifting plate, making their movement more stable and smooth.

[0011] The utility model is further configured as follows: a sliding groove is provided at the bottom of the horizontal plate, the horizontal adjustment mechanism includes a sliding block fixedly connected to the top end of the second screw rod, the top of the sliding block is fixedly connected to a sleeve box, the bottom inner wall of the sleeve box is fixedly connected to an upper spring, the top of the upper spring is fixedly connected to a movable plate, the top of the movable plate is fixedly connected to a vertical rod, the top of the vertical rod is fixedly connected to a top plate, the bottom of the top plate is fixedly connected to two rubber pads, and the two rubber pads are both movably connected to the top of the horizontal plate.

[0012] By adopting the above technical solution, according to the lateral position of the end of the wire, the top plate and the rubber pad are pulled upward by the handle, so that the upper spring is stretched, and the rubber pad does not abut against the top of the horizontal plate, and thus the slider is not fixed. At this time, the top plate, vertical rod, sleeve box, slider and second screw rod can be pulled horizontally by the handle, and then the lateral position of the second screw rod can be adjusted so that the second screw rod is closer to the end of the wire. After the adjustment, the handle is released. At this time, under the pulling force of the upper spring, the top plate and the rubber pad are moved down and firmly abut against the top of the horizontal plate, and then the sleeve box and the slider are fixed.

[0014] By adopting the above technical solution, the slider, the sleeve, the movable plate and the vertical rod can be guided to make their movement more stable and smooth. Because the front and rear width of the rubber pad is greater than the front and rear width of the long hole, the rubber pad can abut against the top of the horizontal plate, so that under the pull of the upper spring, the rubber pad is firmly abutted against the top of the horizontal plate to increase the friction force, which is conducive to fixing the slider.

[0015] The utility model is further configured as follows: a handle is fixedly connected to the top of the top plate.

[0016] By adopting the above technical solution, it is convenient to pull the top plate up and down, and at the same time, the sleeve box and the slider can be pulled left and right by the handle to move horizontally.

[0017] The beneficial effects of the utility model are:

[0018] 1. The utility model pulls the top plate and the rubber pad upward by the handle according to the lateral position of the end of the wire, so that the upper spring is stretched, the rubber pad does not abut against the top of the horizontal plate, and the slider is not fixed. At this time, the top plate, the vertical rod, the sleeve box, the slider and the second screw rod can be pulled horizontally by the handle, and the lateral position of the second screw rod can be adjusted so that the second screw rod is closer to the end of the wire. After the adjustment, the handle is released. At this time, under the pulling force of the upper spring, the top plate and the rubber pad move down and firmly abut against the top of the horizontal plate, so that the sleeve box and the slider can be fixed.

[0019] 2. The utility model pulls the connecting rod, lifting plate and locking rod upward through the pull ring according to the axial position of the end of the wire. At this time, the lower spring is compressed, and the locking rod moves up to disengage from the locking groove without fixing the slide. At this time, the slide can be slidably adjusted along the annular groove, and then the axial position of the second screw rod can be adjusted, so that the end of the wire can be wound and fixed on the outside of the second screw rod, and then the wire can be fastened to the outside of the wire drum to prevent the wire from loosening and falling off. After the adjustment, the pull ring and the connecting rod are released. At this time, under the elastic force of the lower spring, the locking rod moves down and is clamped in the locking groove, and then the slide and the cross plate can be fixed.

[0020] 3. The utility model can not only adjust the axial position of the second screw rod with the wire drum as the axis, but also adjust the lateral position of the second screw rod, so that the ends of the wires at different positions can be effectively wound and fixed on the second screw rod, and then the wires can be effectively fastened to the wire drum, thereby improving the use effect of the device.
