Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically to a guide device for deep hole drilling on curved surfaces made of high-hardness materials. Background Technology

[0002] High-hardness materials refer to materials with extremely high resistance to localized deformation, indentation, or scratches. Their hardness values ​​are typically above Rockwell hardness HRC50 or Vickers hardness HV500. These materials achieve high hardness through methods such as chemical bond strengthening, crystal structure optimization, or alloying. Common types include superhard ceramics, cemented carbide, diamond, and cubic boron nitride.

[0003] In deep hole drilling operations on curved surfaces of high-hardness materials, the extremely high hardness of the material itself causes the drill bit to easily deviate radially in the initial stage of contact with the curved surface due to uneven force. As the drilling depth increases, this deviation gradually accumulates and amplifies. The intense friction between the drill bit and the hole wall not only exacerbates wear but also triggers continuous vibration, leading to out-of-tolerance hole diameter, bending of the hole axis, and in severe cases, even drill bit chipping or breakage. Fragments of the broken drill bit may fly at high speed, directly threatening the safety of the operator; at the same time, the deviated deep hole will damage the structural integrity of the material, making subsequent assembly or processing impossible, increasing rework costs and delaying production schedules. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a high-hardness material curved surface deep hole drilling guide device that can provide good drilling guidance and has high safety.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a guide device for deep hole drilling on curved surfaces of high-hardness materials, comprising:

[0006] The support includes a lower support plate and several legs, the legs being fixedly disposed at the four corners below the lower support plate, and the lower support plate having a through hole in the center;

[0007] The upper pressure plate is placed above the lower support plate, forming a material placement area between them. It is fixed by a fixing component fixed on the lower support plate, and has a positioning hole in the center, which is located directly above the through hole.

[0008] The guide seat is slidably disposed in the positioning hole and can be detached, with a guide hole in the center.

[0009] Furthermore, a foot is fixedly provided below the support leg, and the foot is provided with several fixing holes.

[0010] Furthermore, the fixing component includes an L-shaped plate and a tightening bolt. The L-shaped plate is fixedly mounted on the side wall at the top corner of the upper pressure plate, and its lower end extends downward to one side of the lower support plate. The tightening bolt is mounted on the L-shaped plate and is at the same height as the side wall of the lower support plate, and is used to tighten and fix the lower support plate.

[0011] Furthermore, an anti-slip tightening block is fixedly provided at one end of the tightening bolt near the side wall of the lower support plate.

[0012] Furthermore, the bottom surface of the upper pressure plate near the positioning hole is a curved surface adapted to high-hardness materials.

[0013] Furthermore, the guide seat is integrally formed with a slide bar at its edge, and the positioning hole sidewall is provided with a slide groove that matches the slide bar, with the upper end of the slide groove extending to the upper wall of the upper pressure plate.

[0014] Furthermore, the guide seat is provided with guide holes of various specifications.

[0015] Compared with existing technologies, the advantages of this invention are as follows: the guide seat and the positioning hole of the upper pressure plate are engaged by a sliding strip and groove, allowing for flexible replacement of guide seats of different specifications to adapt to different hole diameter requirements. Simultaneously, a material placement area is formed between the upper pressure plate and the lower support plate to fix the material. The bottom surface of the upper pressure plate conforms to the curved surface of the material, and with the fixing assembly of the L-shaped plate and the tightening bolt, high-hardness materials can be stably clamped and fixed, ensuring that the drill bit accurately drills along the guide hole, achieving good guidance and reducing the risk of deviation. These designs collectively ensure the stability and safety of the drilling process, effectively avoiding safety hazards such as drill bit breakage and material damage caused by unstable devices and material deviation.

[0023] Combined with appendix Figure 2 Appendix Figure 3 The upper pressure plate 3 is placed above the lower support plate 1, forming a material placement area between them. The bottom surface of the upper pressure plate 3 near the positioning hole is a curved surface adapted to high-hardness materials, which can closely fit the material surface, improve the stability of material placement, and reduce the risk of displacement during drilling.

[0024] Combined with appendix Figure 2 Appendix Figure 4 The upper pressure plate 3 is fixed to the lower support plate 1 by a fixing assembly. A positioning hole is located in the center, directly above the through hole. The fixing assembly includes an L-shaped plate 6 and a tightening bolt 7. The L-shaped plate 6 is fixed to the side wall at the top corner of the upper pressure plate 3, with its lower end extending downwards to one side of the lower support plate 1. The tightening bolt 7 is located on the L-shaped plate 6 and is at the same height as the side wall of the lower support plate 1, used to tighten and fix the lower support plate 1. This allows for convenient fixing of the upper pressure plate 3 and the lower support plate 1, quick assembly and disassembly, improved work efficiency, and a secure fixation. An anti-slip tightening block 8 is fixed to one end of the tightening bolt 7 near the side wall of the lower support plate 1, increasing the contact area and friction between the tightening bolt 7 and the lower support plate 1, preventing damage to the surface of the lower support plate 1 during tightening, preventing loosening, and ensuring a secure fixation.

The guide seat 4 has various specifications of guide holes.

[0026] The specific implementation of this utility model is as follows: The support is securely connected to the ground through the fixing holes on the support legs 5. The support legs 5 under the support legs 2 enhance the connection stability between the support and the ground, preventing the device from shaking during drilling. A high-hardness material is placed on the lower support plate 1, and then the upper pressure plate 3 is placed on top of the material, so that the material to be drilled is directly below the positioning hole. The bottom surface of the upper pressure plate 3 adapts to the curved surface of the material, closely fitting the material surface and forming a material placement area with the lower support plate 1, improving the stability of the material placement. Then, the upper pressure plate 3 is fixed by a fixing assembly consisting of an L-shaped plate 6 and a tightening bolt 7. The anti-slip tightening block 8 at one end of the tightening bolt 7 contacts the side wall of the lower support plate 1, tightening and fixing the lower support plate 1, conveniently achieving a firm fixation between the upper pressure plate 3 and the lower support plate 1. According to the drilling requirements, a guide seat 4 of the corresponding specification is selected. The sliding strip 9 on the edge of the guide seat 4 is aligned with the sliding groove on the side wall of the positioning hole, and the guide seat 4 is slidably installed into the positioning hole along the sliding groove. Finally, align the drill bit with the guide hole of the guide seat 4 to begin precise drilling. The guide seat 4 can be flexibly replaced to adapt to different hole diameter requirements, ensuring a stable and safe drilling process.
