[0002] In the process of mechanical manufacturing, hole-opening devices are often used to perform hole-opening processing on parts required in the mechanical manufacturing process. The inner wall of the holes processed by them is smooth and burr-free, and the hole-opening rate is relatively fast. It is an essential mechanical device in some mechanical production processes.

[0003] In the process of using a hole-opening device to open holes in a part, when the hole-opening tool contacts the part to be processed, the part will be subjected to a horizontal component force. When the horizontal component force is greater than the friction force between the part and the operating table, it is very easy for the part to shift on the operating table, and then the hole-opening position of the part will shift, resulting in a reduction in the processing accuracy of the part. Summary of the Utility Model

A first operating plate 4 is slidably connected to the top of the base 1. A second operating plate 5 is slidably connected to the top of the first operating plate 4. A limiting device 2 is arranged on the top of the second operating plate 5. The limiting device 2 includes two limiting plates 21. The two limiting plates 21 are symmetrically arranged on the top of the second operating plate 5. One side of the bottom of the limiting plate 21 is fixedly connected with a screw hole block 22. The inner walls of the two screw hole blocks 22 are respectively threadedly connected with a first threaded rod 23 and a second threaded rod 24. The ends of the first threaded rod 23 and the second threaded rod 24 close to each other are fixedly connected. The thread sizes of the first threaded rod 23 and the second threaded rod 24 are the same and the directions are opposite. Connecting pipes are arranged on the outer surfaces of the first threaded rod 23 and the second threaded rod 24. One side of the two connecting blocks 25 is symmetrically and fixedly connected with one side of the second operating plate 5. One side of the base 1 is fixedly connected with a lifting frame 6. One end of the lifting frame 6 is provided with a hole-opening tool 7. Rollers 8 are arranged at the four corners of the bottom of the base 1. A positioning device 3 is arranged in the middle of the bottom of the base 1. By arranging two limiting plates 21, under the action of the first threaded rod 23 and the second threaded rod 24, rotate the first threaded rod 23 and the second threaded rod 24. The first threaded rod 23 and the second threaded rod 24 will respectively drive a limiting plate 21 connected to the screw hole block 22 to move synchronously and towards each other on the top of the second operating plate 5 until the two limiting plates 21 completely clamp the part on the top of the second operating plate 5, which is beneficial to preventing the part from shifting on the top of the second operating plate 5 and improving the processing accuracy of the part.

[0029] Referring to Figure 2 and Figure 3As shown, bearings 26 are fixedly connected to the outer surfaces of the first threaded rod 23 and the second threaded rod 24, and the outer surfaces of the bearings 26 are fixedly connected to the inner walls of the connecting blocks 25. By providing the bearings 26, the frictional force between the first threaded rod 23 and the second threaded rod 24 and the two connecting blocks 25 can be reduced when the first threaded rod 23 and the second threaded rod 24 are rotated, making it easier to rotate the first threaded rod 23 and the second threaded rod 24; at the far ends of the first threaded rod 23 and the second threaded rod 24 away from each other, operating blocks 27 are fixedly connected, and protrusions are provided on the outer surfaces of the operating blocks 27. By providing the operating blocks 27, rotating the operating blocks 27 can drive the first threaded rod 23 and the second threaded rod 24 to rotate. At the same time, the protrusions are provided on the outer surfaces of the operating blocks 27, which can effectively increase the frictional force on the outer surfaces of the operating blocks 27 and have an anti-slip effect when rotating the operating blocks 27.

[0030] Referring to Figure 2 and Figure 3 As shown, round rods 28 are fixedly connected to the outer sides of the two limiting plates 21 away from each other. The outer surfaces of the round rods 28 are slidably connected to round hole blocks 29, and the bottoms of the two round hole blocks 29 are symmetrically and fixedly connected to the top of the second operation plate 5. By providing the round rods 28, when the two limiting plates 21 move under the action of the first threaded rod 23 and the second threaded rod 24 respectively, the limiting plates 21 will drive the round rods 28 to slide on the inner walls of the round hole blocks 29, which can play a role in limiting the limiting plates 21; on the sides of the two limiting plates 21 close to each other, rubber plates 210 are fixedly connected, and grooves are evenly provided on one side of the rubber plates 210. By providing the rubber plates 210 with grooves, the frictional force on one side of the limiting plates 21 can be increased, making the clamping of the two limiting plates 21 on the parts tighter.

[0031] Referring to Figure 2 and Figure 4 As shown, the positioning device 3 includes a bottom plate 31, the bottom plate 31 is arranged at the bottom of the base 1, threaded insertion rods 32 are symmetrically and fixedly connected to the top of the bottom plate 31, the outer surfaces of the threaded insertion rods 32 are slidably connected to auxiliary blocks 33, and one sides of the two auxiliary blocks 33 are respectively fixedly connected to the two sides of the base 1. By providing the bottom plate 31, when the bottom plate 31 is pushed downward, the bottom plate 31 will drive the threaded insertion rods 32 to slide synchronously on the inner walls of the auxiliary blocks 33 until the bottom of the bottom plate 31 abuts against the ground, then the frictional force and the supporting area between the hole-opening device and the ground can be increased, making it not easy for the hole-opening device to shift and tip over.

[0032] Referring to Figure 2 and Figure 4As shown, nuts 34 are provided on both sides of the auxiliary block 33. The inner walls of the two nuts 34 are threadedly connected to the outer surface of the threaded insertion rod 32. By providing the two nuts 34 and rotating the two nuts 34 respectively, so that one side of the nut 34 abuts against one side of the auxiliary block 33, the bottom plate 31 can be fixed; one end of the threaded insertion rod 32 is fixedly connected with a round block 35, and the outer diameter of the round block 35 is larger than the outer diameter of the threaded insertion rod 32. By providing the round block 35, the end of the threaded insertion rod 32 can be limited, which is beneficial to preventing the nut 34 from disengaging from the threaded insertion rod 32 due to misoperation.

[0033] Working principle: When it is necessary to limit the parts, rotate the operation block 27 to drive the first threaded rod 23 and the second threaded rod 24 to rotate. Under the limitation of the round rod 28, the first threaded rod 23 and the second threaded rod 24 will respectively drive a limiting plate 21 connected to the threaded hole block 22 to move synchronously and towards each other on the top of the second operation plate 5 until the rubber plate 210 on one side of the two limiting plates 21 completely clamps the parts on the top of the second operation plate 5, which is beneficial to preventing the parts from shifting on the top of the second operation plate 5 and improving the processing accuracy of the parts; when it is necessary to position the hole-opening device, push the bottom plate 31 downward to move, and the bottom plate 31 will drive the threaded insertion rod 32 to slide synchronously inside the auxiliary block 33 until the bottom of the bottom plate 31 abuts against the ground, and then rotate the two nuts 34 respectively, so that one side of the nut 34 abuts against one side of the auxiliary block 33, and the bottom plate 31 can be fixed, which can increase the friction and the supporting area between the hole-opening device and the ground, making the hole-opening device not easy to shift and tip over.
