[0002] The ring wire is a new type of efficient and green cutting tool. It usually uses the electroplating nickel process to consolidate diamond abrasives on the annular metal wire. Since the metal wire has high strength, it can cut at a relatively high wire speed. Currently, when cutting an inner hole on a graphite plate with a ring saw, a hole must be drilled in advance at the position to be cut, and then the ring wire is passed through the drilled hole, and then the two ends of the wire are connected, and then the required hole is cut according to the trajectory.

[0003] Currently, when threading the ring wire through the hole drilled in advance on a relatively thick graphite plate, one end of the ring wire needs to be passed through the drilled hole. When threading through a relatively deep hole, due to the insufficient smoothness of the inner wall of the hole, the threading is often inconvenient. Therefore, the utility model proposes a ring saw perforation docking device that is convenient for threading to meet the existing needs. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a ring saw perforation docking device, which is used to solve the problem that when threading through a relatively deep hole, due to the insufficient smoothness of the inner wall of the hole, the threading is often inconvenient.

[0009] Further, connection seats are respectively fixed on both sides of the top of the inner pipe. A convex groove is opened in the connection seat. A convex block is slidably connected in the convex groove. One end of the convex block can extend into the corresponding through groove and is fixedly connected with the corresponding clamping block, and the other end of the convex block extends out of the corresponding connection seat.

[0010] Further, the stepped surfaces on the opposite sides of the two convex blocks are respectively connected to the corresponding connecting seats through compression springs, and arc-shaped grooves are formed on the opposite sides of the two clamping blocks.

[0017] The utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0018] As Figures 1 to 4In the embodiment of the annular wire saw perforation docking device of the present utility model shown, the annular wire saw perforation docking device includes a through pipe 1. Inside the through pipe 1, there is an inner pipe 2 that can move up and down. The top of the inner pipe 2 extends out of the through pipe 1 and is provided with an open mask 3. On both sides of the top of the inner pipe 2, through grooves are respectively opened. Inside the through grooves, there are slidingly connected clamping blocks 4. The two clamping blocks 4 are arranged oppositely. The upper surfaces of the two clamping blocks 4 are both inclined surfaces, and the two inclined surfaces are in an inverted V shape. By adjusting the position of the inner pipe 2 inside the through pipe 1 according to the depth of the hole drilled on the graphite plate, the use lengths of the through pipe 1 and the inner pipe 2 are made longer than the depth of the hole. Thus, the device can be applicable to holes of different depths. One end of the annular wire is inserted into the inner pipe 2 and the inside of the through pipe 1 through the open mask 3. Since the inner walls of the inner pipe 2 and the through pipe 1 are smooth, it is convenient for the annular wire to pass through. And by moving the two clamping blocks 4 relatively, the position of the annular wire after passing through can be positioned. Then, the through pipe 1 is inserted into the hole opened on the graphite plate. By releasing the fixation of the two clamping blocks 4 on the annular wire, and then holding one end of the annular wire, the device is pulled out from the other end of the annular wire. Then, the two ends of the annular wire are connected. Thus, the device can facilitate the perforation docking of the annular wire with the hole opened on the graphite plate, and the wire threading is relatively convenient.

[0019] In an embodiment of the present application, preferably, the top of the through pipe 1 is threadedly connected with a fastening stud 5. One end of the fastening stud 5 abuts against the surface of the inner pipe 2. After adjusting the position of the inner pipe 2 inside the through pipe 1, by rotating the fastening bolt 5, one end of the fastening bolt 5 can be made to tightly press against the surface of the inner pipe 2, so as to fix the relative position between the inner pipe 2 and the through pipe 1.

[0020] In an embodiment of the present application, preferably, the bottom of the through pipe 1 is in a flared shape, so as to facilitate inserting the bottom of the through pipe 1 into the hole opened on the graphite plate.

[0021] In an embodiment of the present application, preferably, on both sides of the top of the inner pipe 2, connection seats 6 are respectively fixed. Inside the connection seats 6, convex grooves are opened. Inside the convex grooves, there are slidingly connected convex blocks 7. One end of the convex block 7 can extend into the corresponding through groove and is fixedly connected with the corresponding clamping block 4. The other end of the convex block 7 extends out of the corresponding connection seat 6. By moving the two convex blocks 7, the two clamping blocks 4 can be made to move relatively.

[0022] In an embodiment of the present application, preferably, the stepped surfaces on the opposite sides of the two convex blocks 7 are respectively connected with the corresponding connection seats 6 through compression springs 8. Arc-shaped grooves 9 are opened on the opposite sides of the two clamping blocks 4, so that the two convex blocks 7 can move relatively under the action of the compression springs 8. The setting of the arc-shaped grooves 9 can limit the annular wire when clamping the annular wire.

[0023] In an embodiment of the present application, preferably, an L-shaped groove is provided on the convex block 7, a slot 10 is provided on the connecting seat 6, an L-shaped rod 11 that can move up and down is provided in the L-shaped groove, one end of the L-shaped rod 11 can be inserted into the corresponding slot 10, the other end of the L-shaped rod 11 extends out of the L-shaped groove and is fixed with a push plate 12. When the two L-shaped rods 11 are respectively inserted into the corresponding slots 10, the annular wire is not clamped at this time. When the two L-shaped rods 11 are respectively separated from the corresponding slots 10, the two convex blocks 7 can move relative to each other under the action of the compression spring 8.

[0024] When the present utility model is in use, the position of the inner tube 2 inside the pipe 1 is adjusted according to the depth of the hole drilled in the graphite plate, so that the use lengths of the pipe 1 and the inner tube 2 are longer than the depth of the hole. By rotating the fastening bolt 5, one end of the fastening bolt 5 abuts against the surface of the inner tube 2, so that the relative position between the inner tube 2 and the pipe 1 can be fixed, and thus the device can be applicable to holes of different depths. One end of the annular wire is inserted into the inner tube 2 and the pipe 1 through the open mask 3. Since the inner walls of the inner tube 2 and the pipe 1 are smooth, it is convenient for the annular wire to pass through. When the two L-shaped rods 11 are respectively separated from the corresponding slots 10, the two convex blocks 7 can move relative to each other under the action of the compression spring 8, driving the two clamping blocks 4 to move relative to each other, and the position after the annular wire passes through can be fixed and positioned. Then the pipe 1 is inserted into the hole opened in the graphite plate. By pulling the two convex blocks 7 in opposite directions, the two L-shaped rods 11 are respectively inserted into the corresponding slots 10, and the compression spring 8 stores energy, releasing the fixation of the two clamping blocks 4 on the annular wire. Then hold one end of the annular wire and pull out the device from the other end of the annular wire, and then connect the two ends of the annular wire, so that the device can facilitate the perforation docking of the annular wire and the hole opened in the graphite plate, and the wire threading is relatively convenient.
