[0003] When drilling ring forgings, it is necessary to simply limit the forging position. However, multiple holes need to be drilled on the end wall of the forging. After positioning, it is not convenient to change the position of the forging, resulting in poor convenience and efficiency when machining drilled forgings. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a drilling machine for ring forgings:

[0022] like Figure 1-4As shown, a ring forging drilling machine includes a support frame 1 with a concave shape, a motor 2 fixed to the top wall of the support frame 1, and a drill bit 3 for drilling the ring forging, which is driven to the lower end of the motor 2. A cylinder 4 is fixed to the bottom left end wall of the support frame 1. A rectangular top plate 7 is driven to the upper end of the cylinder 4. A rectangular plate groove 8 is vertically penetrating inside the top plate 7. A lead screw 10 is rotatably connected to the left and right walls of the front side of the plate groove 8. A pair of rectangular connecting pieces 11 that move sideways and oppositely are threaded to the end of the lead screw 10. A rectangular fixed plate 12 is fixed to the side wall of the connecting piece 11 away from the plate groove 8. A cylindrical top column 13 is rotatably connected to the upper end wall of the fixed plate 12.

[0023] A rectangular storage seat 5 is provided at the bottom of the support frame 1 near the right side of the cylinder 4. The storage seat 5 has a rectangular cavity 6 for storing the drilling debris falling from the forging. There are two connecting plates 11. At the same time, a slide bar 9 is horizontally inserted and movably connected to the end wall of the connecting plate 11 fixed to the side of the top plate 7 away from the lead screw 10. The slide bar 9 is rectangular. The two ends of the slide bar 9 are fixed to the two end walls of the plate groove 8 of the top plate 7 respectively. The thickness of the slide bar 9 is the same as the thickness of the solid plate 12. The solid plate 12 and the slide bar 9 together form a support for the ring forging. The solid plate 12 and the upper end wall of the top column 13 are both provided with scale marks 14 for reading the rotation angle of the top column 13.

[0024] Working principle:

[0025] The motor 2, which is fixed to the top of the support frame 1, runs and drives the drill bit 3 to rotate;

[0026] The annular forging is placed at the top post 13 of the fixed plate 12, with one top post 13 placed in the inner opening of the forging and the other top post 13 placed on the outer side of the forging. At this time, the screw 10 is rotated, and the threaded drive fixed plate 12 is located on the front connecting piece 11, causing the connecting piece 11 to move laterally, so that the two top posts 13 are close to each other and respectively stick to and clamp the inner and outer walls of the forging, thus providing simple positioning and limiting of the forging.

[0027] When cylinder 4 operates, it drives top plate 7 to move upward, so that the forging comes into contact with drill bit 3 for drilling.

[0028] The bottom end face of the forging contacts the upper end face of the connecting piece 11 and the fixed plate 12, providing support and generating friction. The simple limiting forging prevents the forging from rotating freely and changes the drilling position of the forging.

[0029] When it is necessary to change the drilling position, the rotation applies an external force to the forging, driving the forging to rotate and clamping the top post 13 of the forging, so that it can rotate. When the forging rotates, the top post 13 and the forging clamp generate friction. The top post 13 rotates with the forging. At this time, the scale mark 14 on the upper wall of the fixed plate 12 and the top post 13 is read, which makes it convenient to rotate the forging accurately, change the drilling position of the forging, and precisely adjust the drilling position. The drilling and adjustment are more flexible and convenient.

[0030] Two connecting pieces 11 are provided, which are fixed to the front and rear walls of the solid plate 12 respectively. The connecting piece 11 located on the front side of the solid plate 12 moves with the slide bar 9, making the solid plate 12 more stable when it is displaced. The connecting piece 11 located on the rear side of the solid plate 12 drives the lead screw 10, which facilitates the rotation of the lead screw 10 and the lateral movement of the solid plate 12. When the annular forging is placed, the axial side wall of the forging is facing the drill bit 3, and the axial end wall of the forging is drilled.

[0031] In addition, the debris generated during drilling falls into the cavity 6 of the storage base 5 for centralized collection, which facilitates subsequent centralized processing.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
