A first concave limiting step is provided at the connection between the needle head and the needle body, and the first limiting step is provided corresponding to the clamping mechanism of the stop assembly of the automatic bead threading device. The diamond bead threading needle with a concave step provided by the present invention prevents the threading needle from retreating due to friction generated when beads pass through the threading needle or resistance generated by blockage of the bead through-hole, thereby preventing the beads from falling. An automatic bead threading device is also provided. By adopting the diamond bead threading needle of the present invention, the situation in which the diamond bead threading needle slides backward under the resistance of the beads when the bead moving assembly fiddles with the beads is prevented, thereby enabling the beads to be accurately moved to the corresponding position on the wire rope, thereby improving the qualified rate of the wire saw.

Description

Technical Field

[0001] The invention relates to the field of wire saw preparation for wire saw machines, in particular to a bead threading needle for diamond wire saws and automatic bead threading equipment composed of the needle and the needle. Background Art

[0002] Most companies in the diamond wire saw industry still use manual wire threading, which is inefficient, costly, and prone to errors. A few companies use automated equipment for wire threading.

[0003] The prior art CN2020113690903 discloses a linkage type automatic diamond bead stringing machine, which includes a bead supply unit, a bead pushing unit, and a rope end fixing unit installed on the machine platform. The rope end fixing unit is in front of the bead pushing unit, and the bead supply unit is on one side of the bead pushing unit. The bead supply unit includes a flow cutoff baffle; the bead pushing unit includes a bead clamping device, a hollow push tube and a push tube driving mechanism; the bead clamping device includes a support platform, a regulating cover and a clamping driving mechanism; the rope end fixing unit includes a clamping mechanism. This invention still directly uses steel wire rope for bead stringing; however, in the process of threading the diamond beads into the steel wire rope, the friction generated when the beads pass through the steel wire rope will cause the steel wire rope to move backward or bend. When a certain number of beads are threaded through, the steel wire rope is no longer in the original predetermined position, and the beads will not be able to pass through and will fall off; moreover, the rope end of the steel wire rope can only carry a certain number of beads. When the beads need to be moved to a specified position on the steel wire rope, friction will also be generated between the beads and the steel wire rope, causing the steel wire rope to move, affecting the subsequent threading of the beads. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a bead threading needle for a diamond wire saw and an automatic bead threading device composed of the same, which guides the wire rope by using a diamond bead threading needle with steps and limits the threading needle by using limiting steps; thereby avoiding the friction generated when the beads pass through the threading needle or the resistance generated by the blockage of the bead through-hole causing the threading needle to retreat, thereby preventing the beads from falling.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] Provided is a bead threading needle for a diamond wire saw, comprising: a needle head, a needle body, and a needle tail, wherein the needle head, needle body, and needle tail are connected in sequence; the needle head is conical, the needle tail is provided with an axial connecting hole, and a concave first limiting step is provided at the connection between the needle head and the needle body, the first limiting step being arranged corresponding to the clamping mechanism of the stop assembly of the automatic bead threading device; the first limiting step can prevent the diamond bead threading needle from being displaced during use.

[0007] Preferably, the first limiting step is arranged around the diamond bead threading needle, and after the diamond bead threading needle rotates, the clamping device can still be clamped in the first limiting step.

[0008] Preferably, a second concave limiting step is provided at the connection between the needle body and the needle tail; it not only facilitates the clamping of the diamond bead threading needle by the stop assembly and improves the stability during the clamping process, but also can further prevent the diamond bead threading needle from being displaced during the bead moving process.

[0009] Preferably, the connection hole and the steel wire rope are connected and fixed by any one of adhesive bonding (adhesive includes adhesive glue, tin wire and the like), welding and external force clamping mechanism.

[0010] Preferably, the external force clamping mechanism is a locking nut, which is sleeved on the needle tail of the diamond bead threading needle, and a locking groove is provided at the needle tail connecting hole. The inner diameter of the connecting hole is reduced by rotating the locking nut. The locking nut is used to fix the wire rope, so that the connecting hole at the tail of the diamond bead threading needle can clamp different wire rope ends (the two ends of the existing wire saw are connected by different methods: such as threaded connection, hinged connection, snap connection, etc., and the rope ends of different connection methods are different), thereby improving the practicality of the diamond bead threading needle.

[0011] Preferably, the outer diameter of the locking nut is less than or equal to the maximum outer diameter of the diamond bead threading needle to prevent the locking nut from having an outer diameter that is too large and cannot pass through the through hole of the bead.

[0012] Preferably, the connecting hole is provided with an internal thread that matches the external thread of the wire saw.

[0013] It should be noted that this solution is applicable to a rope saw with both ends connected by threads.

[0014] An automatic bead threading device is also provided, comprising: a diamond bead threading needle as described above, a bead moving assembly, a stop assembly, a bead pushing assembly and a frame; the stop assembly is arranged on the frame, the diamond bead threading needle is clamped on the stop assembly, the bead pushing assembly is coaxially arranged with the diamond bead threading needle in the extension direction of the needle head, and can push the beads onto the diamond bead threading needle, and the bead moving assembly is arranged above the diamond bead threading needle, and can move the beads toward the extension direction of the needle tail.

[0015] Preferably, the stop assembly includes a clamping mechanism and a translation mechanism, the clamping mechanism is provided on the translation mechanism, and the translation mechanism can slide on the frame.

[0016] Preferably, the stop assembly includes a first stop member and a second stop member, and the first stop member and the second stop member are respectively arranged corresponding to the first limit step and the second limit step at both ends of the diamond bead threading needle.

[0017] Beneficial effects of the present invention:

[0018] The present invention provides a bead threading needle for a diamond wire saw. The needle has a connecting hole at one end thereof, so that the needle can be better connected and fixed with the front end of the wire rope. A first limiting step is provided at the connecting portion between the needle head and the needle body to prevent the needle from retreating due to friction generated when the beads pass through the needle. The front end is designed to be conical, so that the needle can pass through the through hole of the beads and can pierce beads that are partially blocked or have different sizes of through holes of the beads, thereby greatly improving the qualified rate, stability and efficiency of threading the beads through the wire rope.

[0019] An automatic bead threading device is also provided. By adopting the diamond bead threading needle of the present invention, the diamond bead threading needle is prevented from sliding backward under the resistance of the beads when the bead moving component is fiddling with the beads, so that the beads can be accurately moved to the corresponding position on the wire rope, thereby improving the qualification rate of the rope saw.
