[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a threaded hole pre-processing device, including a worktable 1. A movable plate 3 is movably mounted inside the worktable 1 via a first sliding groove 2 and a lateral adjustment mechanism. Adjustment plates 11 are movably mounted inside both ends of the movable plate 3 via second sliding grooves. A clamping plate 13 is movably mounted inside the top of the adjustment plate 11 via a third sliding groove 18. The clamping plate 13 is T-shaped. A limit mechanism is provided between the clamping plate 13 and the third sliding groove 18. The third sliding groove 18 is located at the top of the adjustment plate 11. Internally, the limiting mechanism includes a locking block 20 and a spring 19. The locking block 20 is slidably disposed inside one end of the clamping plate 13. The top of the workbench 1 is provided with a drilling mechanism, which includes a column 6, a horizontal plate 7, a vertical hydraulic cylinder 8, and an adjusting box 9. The clamping plate 13 can move inside the third sliding groove 18, which facilitates the movement of the casting back and forth through the clamping plate 13, and facilitates drilling at different positions on the casting. The locking block 20 and other limiting mechanisms can limit the clamping plate 13, thereby improving the stability of the clamping plate 13 and the casting.

[0022] In this embodiment, the first slide groove 2 is formed inside the workbench 1, and the movable plate 3 is slidably installed inside the first slide groove 2. The lateral adjustment mechanism includes a fixed plate 4 and a base plate 5. The fixed plate 4 is fixedly installed at the bottom middle position of the movable plate 3, and the base plate 5 is fixedly set at both ends of the bottom of the first slide groove 2. A screw 14 is rotatably installed between the two base plates 5. The fixed plate 4 is screwed to the outside of the screw 14. A servo motor 15 is fixedly installed on one side of the right base plate 5. The output shaft of the servo motor 15 is fixedly connected to one end of the screw 14. The servo motor 15 drives the screw 14 to rotate, which facilitates the sliding of the movable plate 3 inside the first slide groove 2 through the screwing action of the screw 14 and the fixed plate 4, which facilitates the subsequent adjustment of the casting in the left and right directions.

[0023] In this embodiment, the second slide groove is symmetrically opened inside both ends of the movable plate 3. The adjusting plate 11 is slidably installed inside the second slide groove. The movable plate 3 is U-shaped. A transverse hydraulic cylinder 12 is symmetrically fixed at both ends of the movable plate 3. The output rod of the transverse hydraulic cylinder 12 is fixedly connected to the adjusting plate 11. The transverse hydraulic cylinder 12 can adjust the adjusting plate 11 laterally. The adjusting plate 11 drives the clamping plates 13 to move closer to each other, which facilitates the clamping and fixing of the casting. The second slide groove can limit the adjustment plate 11 and improve the stability of the adjustment plate 11.

[0024] In this embodiment, one end of the locking block 20 is fixedly connected to the spring 19, the spring 19 is disposed inside the clamping plate 13, and the inner wall of the third sliding groove 18 is provided with slots at equal intervals corresponding to the position of the locking block 20, and one end of the locking block 20 is engaged inside the slot.

[0025] In this embodiment, the columns 6 are symmetrically fixed on both sides of the top of the workbench 1, the horizontal plate 7 is fixedly fixed on the top of the columns 6, and the adjustment box 9 is set below the horizontal plate 7 by a vertical hydraulic cylinder 8.

The slide rods 10 can limit the adjustment box 9 and improve the stability of the adjustment box 9. The vertical hydraulic cylinder 8 drives the adjustment box 9, drive motor 16 and drill bit 17 to descend, which facilitates the machining of round holes on the casting.

[0026] When using this threaded hole pre-machining device, the casting to be drilled is placed between the two clamping plates 13. The transverse hydraulic cylinder 12 is activated, which drives the adjusting plate 11 to slide inside the second slide groove. The adjusting plate 11 also drives the clamping plates 13 to move closer together, clamping both ends of the casting with the clamping plates 13 for easy clamping and fixing. One end of the clamping plate 13 can support the bottom of the casting, allowing the casting to be suspended above the worktable 1. The servo motor 15 is activated, which drives the screw 14 to rotate. Through the screw connection between the screw 14 and the fixed plate 4, the moving plate 3 slides laterally inside the first slide groove 2. The moving plate 3, through the adjusting plate 11 and the clamping plates 13, moves the casting left and right. The clamping plates 13 slide backward inside the third slide groove 18. 3. The casting is moved to the rear. The set block 20 is locked in the corresponding slot under the elastic force of the spring 19, which can limit the clamping plate 13 and improve the stability of the clamping plate 13 and the casting. The position on the casting that needs to be drilled is moved to below the drill bit 17. The vertical hydraulic cylinder 8 is started. The vertical hydraulic cylinder 8 drives the adjusting box 9 to descend. The set slide rod 10 can limit the adjusting box 9, thereby improving the stability of the adjusting box 9. The drive motor 16 is started. The drive motor 16 drives the drill bit 17 to rotate. As the adjusting box 9 descends, it can drive the drill bit 17 to descend, which is convenient for drilling holes in the casting. It is convenient to process round holes at different positions on the casting. In addition, the clamping plate 13 can separate the casting from the worktable 1, avoiding drilling on the worktable 1 and affecting the use of the worktable 1, which can improve the practicality of the device.
