In the prior art, the top of the plug is usually grooved by drilling.

[0003] When the existing drilling machine tool drills a workpiece, a three-jaw chuck is usually used to fix the workpiece. However, the outside of the plug is provided with threads, and using a three-jaw chuck to fix it will damage the external threads, thereby affecting the finished product quality of the plug. At the same time, the volume of the plug is small and the processing quantity is large. Using a traditional three-jaw chuck for fixing will cause the problem of reduced processing speed.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0021] The present utility model provides a technical solution. Please refer to Figure 1 and Figure 2 , a device for processing the inner groove of a screw plug, comprising: a frame 1, a hydraulic cylinder 2, a punching unit 3 and a load-bearing platform 4. This solution is a structural improvement of the non-electronic component part on the basis of the existing drilling machine tool. Among them, the frame 1, the hydraulic cylinder 2, the punching unit 3 and the load-bearing platform 4 are common drilling machine tool products that have been popularized in the existing technology. The hydraulic cylinder 2 can drive the punching unit 3 to move up and down. The punching unit 3 includes a cross-axis moving platform and a drilling machine, and can perform drilling processing on the screw plug. The load-bearing platform 4 can support the placing mechanism 5.

[0022] Please refer to Figure 3 , Figure 4 and Figure 5 , the hydraulic cylinder 2 and the load-bearing platform 4 are both assembled on the top of the frame 1. The punching unit 3 is assembled outside the hydraulic cylinder 2. A placing mechanism 5 is arranged on the top of the load-bearing platform 4. The placing mechanism 5 includes a base 51. The base 51 can slide left and right on the top of the load-bearing platform 4. A first perforated plate 52 and a second perforated plate 53 are respectively arranged on the top of the base 51. The first perforated plate 52 and the second perforated plate 53 can fix the screw plug by alternately matching the circular grooves 55 inside. An air cylinder 56 is connected to the outside of the base 51. The air cylinder 56 can push the first perforated plate 52 to move. The air cylinder 56 is connected to the first perforated plate 52.

[0023] The tops of the first perforated plate 52 and the second perforated plate 53 are evenly provided with round grooves 55, the top of the base 51 is evenly provided with placement grooves 512, a lever mechanism 6 is connected between the first perforated plate 52 and the second perforated plate 53, the top of the load-bearing platform 4 is evenly provided with grooved blocks 41, the top of the grooved block 41 is slidably connected with a guide block 42, the guide block 42 is connected with the base 51, and the grooved block 41 cooperating with the guide block 42 can guide the base 51 so that the base 51 can rock left and right linearly.

[0024] The lever mechanism 6 includes a horizontal shaft 61 which can rotate. The horizontal shaft 61 is connected to the base 51 through a pedestal bearing. Both outer ends of the horizontal shaft 61 are slidably connected with auxiliary arms 62. The auxiliary arms 62 can make the horizontal shaft 61 expand and contract. A pull rope 63 is connected to the outside of the auxiliary arm 62. The pull rope 63 prevents the horizontal shaft 61 from interfering with the first perforated plate 52 and the second perforated plate 53 when rotating. The two pull ropes 63 are respectively connected to the first perforated plate 52 and the second perforated plate 53.

[0025] A bench 57 is connected to the outside of the cylinder 56. The bench 57 is connected to the base 51. The bench 57 can fix and assemble the cylinder 56. The bottom of the first perforated plate 52 is evenly provided with sliders 58, and the top of the base 51 is evenly provided with sliding grooves 513 adapted to the sliders 58. The sliders 58 cooperating with the sliding grooves 513 can fix and limit the first perforated plate 52.

[0026] The bottom of the second perforated plate 53 is evenly provided with sliding blocks 59, and the top of the base 51 is evenly provided with sliding grooves 511 adapted to the sliding blocks 59. The sliding blocks 59 cooperating with the sliding grooves 511 can guide the second perforated plate 53 to move linearly. The round groove 55 is arranged directly above the placement groove 512, and the diameter of the round groove 55 is 1.5 times the diameter of the placement groove 512. Bottom grooves 54 are opened at both ends of the bottom of the first perforated plate 52. The placement groove 512 can fix the plug, and the bottom groove 54 can facilitate the transmission of the lever mechanism 6.

[0027] In this solution, first, the plugs are laid on the top of the second perforated plate 53. The base 51 is shaken left and right to move. Through the vibration force and the special shape of the plugs, the plugs are evenly inserted into the inside of the round grooves 55, or the plugs are directly placed inside the round grooves 55. Then, the cylinder 56 is started to drive the first perforated plate 52 to move. When the first perforated plate 52 moves, it will pull the horizontal shaft 61 to rotate through the pull rope 63, and then pull the second perforated plate 53 to move in the opposite direction to the first perforated plate 52 through the pull rope 63 at the other end, so as to fixedly clamp the plugs inside the round grooves 55. The hydraulic cylinder 2 is started to drive the drilling unit 3 to descend, and then the inner groove of the plug is drilled.

[0028] Before processing the screw plug, by using the added placement mechanism 5 to cooperate with shaking or directly placing the screw plug, a large number of screw plugs can be restricted. Subsequently, the punching unit 3 can process a large number of screw plugs at one time, improving the processing speed of the screw plug. Also, by adding the lever mechanism 6, through the method of misaligned clamping, the screw plug can be quickly restricted inside the placement mechanism 5, avoiding the screw plug from shaking during processing, so that a large number of screw plugs can be processed quickly.
