Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to an auxiliary tooling for straightening drill rods on an external cylindrical grinding machine. Background Technology

[0002] In the field of mechanical technology, cylindrical grinding machines are key equipment for achieving precision machining of the outer cylindrical surface of workpieces. With the increasing multi-functionality and automation of cylindrical grinding machines, higher demands are being placed on their stability and versatility. To address this, an auxiliary tooling for straightening drill rods in cylindrical grinding machines has been developed. This tooling aims to solve problems such as the lack of straightening functionality in traditional cylindrical grinding machines, inconvenient adjustment during installation, and drill rod bending. It provides a straightening function for cylindrical grinding machines, reducing errors during transportation.

[0003] Currently, the most common methods for fixing drill pipe straightening clamps are fixed clamps and bolt clamps. Bolted clamps require tightening each bolt individually and repeatedly calibrating the position, and they are highly dependent on tools and complex to disassemble. Fixed clamps cannot adjust the position of the V-blocks and cannot be adapted to different specifications of drill pipes. Therefore, there is an urgent need for a drill pipe straightening auxiliary tool that can be adapted to various specifications of drill pipes and can be quickly disassembled. Utility Model Content

[0019] Reference Figure 4 and Figure 5The sliding assembly includes a slider 11, which serves as the sliding platform for the entire tooling, ensuring quick disassembly. The outer wall of the slider 11 is fixedly connected to the lower surface of the base 2. The outer wall of the slider 11 is slidably connected to a T-shaped guide rail 10, providing a foundation for the slider 11 to slide. As a snap-fit ​​platform, the outer wall of the T-shaped guide rail 10 is fixedly connected to the upper surface of the worktable 1. The inner wall of the T-shaped guide rail 10 is slidably connected to a locking post 20, which serves as a key structure for fixing the slider 11 and achieving a fixing function. A spring 23 is fixedly connected to the outer wall of the locking post 20, providing a power source for the opening and closing of the locking post 20. One end of the spring 23 is fixedly connected to a fixed... Fixed post 3 22 is used to fix spring 23. Movable post 4 21 is fixedly connected to both ends of fixed post 3 22, providing an overall frame for the buckle and driving the buckle 20 to achieve the fixing function. A fixing block 24 is fixedly connected inside movable post 4 21, providing support for connecting the buckle 20 and movable post 4 21. Movable post 3 18 is fixedly connected to the outer wall of movable post 4 21, moving linearly within the inner wall of the fixing ring 17. Fixed post 1 14 is slidably connected to the inner wall of movable post 4 21. Rotating post 2 15 is threadedly connected to the outer wall of fixed post 1 14, forming a common threaded connection that allows the rotating part of rotating post 2 15 to rotate. The motion is converted into linear motion of the fixed column 14. The outer wall of the rotating column 15 is slidably connected to the fixed column 16, ensuring that the fixed column 16 is always sliding on the outer wall of the rotating column 15. The fixed ring 17 and the rotating column 15 are fixed to ensure the snap-fit ​​effect. The outer wall of the rotating column 15 is rotatably connected to the fixed ring 17, which fits against the outer wall of the T-shaped guide rail 10 and works with the snap-fit ​​column 20 to achieve the clamping effect and fixation. The outer wall of the rotating column 15 is fixedly connected to the rotating column 13, which is an integrated structure with the rotating column 15 and serves as a handle for rotating the rotating column 15. The fixed ring 17 has an opening inside. The groove 19 ensures that the second fixed column 16 slides within the groove 19, connecting the second rotating column 15 and the fixed ring 17. The third moving column 18 is slidably connected to the outer wall of the fixed ring 17. The inner wall of the locking column 20 is rotatably connected to the outer wall of the fixed block 24. One end of the fixed ring 17 is attached to the outer wall of the T-shaped guide rail 10. The bidirectional screw 4 is rotatably connected to the inner wall of the base 2. The outer wall of the second fixed column 16 is fixedly connected to the upper surface of the fixed ring 17. The first rotating column 13 is positioned above the second fixed column 16. One end of the bidirectional screw 4 is rotatably connected to the inner wall of the rotating block 3. The outer wall of the pad 7 is fixedly connected to the upper surface of the second V-shaped block 12.

[0020] Working principle: When the auxiliary tooling for straightening drill rods on an external cylindrical grinding machine is needed, the handwheel 5 can be turned to drive the fixed double-acting screw 4 to rotate synchronously. The double-acting screw 4 has threads in opposite directions on its outer wall. The threads connect V-block 1 6 and V-block 2 12, so that rotating the handwheel 5 can make V-block 1 6 and V-block 2 12 slide on the upper surface of the base 2, thereby adjusting the position between V-block 1 6 to adapt to drill rods 1 9 of different lengths. At the same time, pads 7 of different specifications are fixed above V-block 1 6 by bolts 8 to adapt to drill rods 1 9 of different specifications. In addition, two sliders 11 are fixed on the bottom surface of the base 2, and a T-shaped guide rail 10 is fixed on the worktable 1. The auxiliary tooling can be quickly fixed and disassembled on the worktable 1 by means of a buckle. The inner wall of the rotating column 2 15 is threaded. By rotating the rotating column 2 15, the fixed column 1 14 and the moving column 4 21 move down, and the clamping column 20 closes until the clamping column 20 slides into the slider 11. Rotating the rotating column 2 15 in the opposite direction compresses the spring 23, and the clamping column 20 rotates on the outer wall of the fixed block 24 and is released, thereby achieving the purpose of fixing the slider 11. Conversely, rotating the rotating column 2 15 in the opposite direction closes the clamping column 20, which can quickly remove the buckle and thus remove the auxiliary tooling.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
