Detailed Implementation

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0022] Reference Figures 1-3 An adjustable casting drilling device includes a support frame 3. A drilling assembly 1 is bolted to the top of one side of the support frame 3. The drilling assembly 1 includes a mounting bracket fixed to the support frame 3. A cylinder is fixed on the mounting bracket. A first linear motor is fixed to one end of the piston rod of the cylinder. A second linear motor is fixed to the moving part of the first linear motor. A drilling machine, model Z516, is fixed to the power part of the second linear motor. The cylinder controls the up and down movement of the drilling machine, and the first and second linear motors control the horizontal position of the drilling machine. The drilling assembly 1 is started to drill the casting. The position of the drill bit and the drilling depth on the drilling machine of the drilling assembly 1 can be adjusted as needed.

[0023] Specifically, the top of the support frame 3 has two sliding grooves 8, and push blocks 4 are slidably connected in both grooves 8. First fixing plates 6 are bolted to both sides of the support frame 3, and threaded rods 7 are rotatably connected between the first fixing plates 6. The bottom of the push blocks 4 is threadedly connected to the threaded rods 7. The top of the support frame 3 is bolted to a first rotating frame 10, and a second rotating frame 11 is rotatably connected to the top of the first rotating frame 10. A support plate 2 is welded to the top of the second rotating frame 11. Two connecting rods 9 are bolted to the bottom of the support plate 2, and the connecting rods 9 contact the inclined surfaces on the adjacent push blocks 4. The upper surface of the support plate 2 is bolted to... The upper surface of the fixed frame 18 and the support plate 2 is provided with a clamping assembly. Rotating the threaded rod 7 causes the two push blocks 4 to move along the slide groove 8 in the same direction. One connecting rod 9 moves downward along the inclined surface of its corresponding push block 4, and the other connecting rod 9 moves upward along the inclined surface of its corresponding push block 4. The connection point between the first rotating frame 10 and the second rotating frame 11 is the rotation point, which causes the support plate 2 to tilt. The tilt angle of the support plate 2 is controlled by adjusting the distance the push block 4 moves. At the same time, the tilt of the support plate 2 causes the casting clamped on the fixed frame 18 to tilt, which makes it easier for the drill bit on the drilling assembly 1 to drill tilted holes in the casting.

[0024] It should be noted that the clamping assembly includes two second fixing plates 14, which are fixed to the upper surface of the support plate 2 by bolts. A bidirectional lead screw 15 is rotatably connected between the two second fixing plates 14. Two sliders 17 are threaded to the outer side of the bidirectional lead screw 15. A connecting frame 13 is fixed to the top of the sliders 17 by bolts. A clamping plate 12 is fixed to the top of the connecting frame 13 by bolts. The clamping plate 12 is in contact with the upper surface of the horizontal plate of the fixing frame 18. Rotating the bidirectional lead screw 15 moves the two sliders 17 to the required position along the slide rail 16, thereby causing the connecting frame 13 to drive the clamping plate 12 to move until the clamping plate 12 contacts the casting, so that the two clamping plates 12 position and clamp the casting. Two slide rails 16 are fixed to the upper surface of the support plate 2 by bolts, and the sliders 17 are slidably connected to the slide rails 16. The slide rails 16 can guide the sliders 17 and prevent the sliders 17 from tilting during movement.

[0025] In this utility model, a locking nut 5 is threadedly connected to the outer side of one end of the threaded rod 7 that passes through the first fixing plate 6, and the locking nut 5 is in contact with the adjacent first fixing plate 6. The locking nut 5 can further restrict the position of the threaded rod 7 and prevent the threaded rod 7 from easily reversing. One end of the threaded rod 7 passes through the first fixing plate 6 and is welded with a knob to facilitate the rotation of the threaded rod 7. The first rotating frame 10 is located in the middle position between the two push blocks 4, the second rotating frame 11 is located between the two connecting rods 9, and the drilling assembly 1 is located on top of the fixing frame 18.

[0026] Working principle: When drilling a square casting, first place the square casting in the middle of the upper surface of the fixing frame 18. Adjust the distance between the two clamping plates 12 according to the width of the casting, i.e., rotate the double-acting screw 15 to move the two sliders 17 along the slide rail 16 to the required position, thereby causing the connecting frame 13 to move the clamping plates 12 until they contact the casting, positioning and clamping the casting. Then, start the drilling assembly 1 to drill the casting. Adjust the position of the drill bit and the drilling depth of the drilling assembly 1 as needed. When drilling an inclined hole is required... When the operator rotates the knob, the threaded rod 7 drives the two push blocks 4 to move along the slide groove 8 in the same direction. One connecting rod 9 moves downward along the inclined surface of its corresponding push block 4, and the other connecting rod 9 moves upward along the inclined surface of its corresponding push block 4. The connection point between the first rotating frame 10 and the second rotating frame 11 is the rotation point, which causes the support plate 2 to tilt. The tilt angle of the support plate 2 is controlled by adjusting the distance the push block 4 moves. At the same time, the tilt of the support plate 2 causes the casting clamped on the fixed frame 18 to tilt, which makes it easier for the drill bit on the drilling assembly 1 to drill tilted holes in the casting.

[0027] The composition and control of the drilling assembly 1 are common knowledge to those skilled in the art, and this application is a direct application of the prior art, so it will not be described in detail.

[0028] This utility model has been described through the above embodiments. Those skilled in the art will understand that this utility model is not limited to the above embodiments. Many more modifications can be made based on the teachings of this utility model, and all such modifications fall within the scope of protection claimed by this utility model.
