Description

Technical Field

[0001] The utility model relates to the field of processing bench drills, in particular to a bench drill for precision processing of small holes. Background Art

[0002] A small hole precision machining bench drill is a special drilling device that combines vibration machining technology to improve drilling accuracy and efficiency. This bench drill is usually used to create small holes in hard or difficult-to-machine materials, such as metals, ceramics or composite materials. Usually, the features of a small hole precision vibration machining bench drill may include a high-speed rotating drill bit, a high-precision positioning system, adjustable vibration parameters and an advanced control system. These features enable the bench drill to achieve higher accuracy, faster speed and longer tool life during the machining process.

[0003] When the existing small hole precision processing bench drill is performing processing operations, material fragments may be splashed due to the high-speed rotation of the drill bit during the drilling process. In addition, since the traditional operating working drill bit is directly exposed to the outside, when the operator accidentally touches the rotating drill bit with his hands or other tools due to improper operation, it may cause safety hazards. Therefore, when designing the small hole precision processing bench drill, it is necessary to provide a protection mechanism to play a better protective function and improve the overall safety. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a small hole precision processing bench drill to solve the technical problems of safety hazards and inability to effectively prevent splashing during use of traditional small hole precision vibration processing bench drills.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a small hole precision processing bench drill, comprising an adjustment mechanism and a drill rig, wherein a mounting head and a protection mechanism are arranged at the bottom of the drill rig, wherein the protection mechanism comprises a mounting groove, wherein the internal thread of the mounting groove is connected with a mounting ring, wherein a retaining ring is arranged at the bottom of the mounting ring, wherein a plurality of retaining rings are arranged, wherein the plurality of retaining rings are arranged from top to bottom, and the plurality of retaining rings are engaged with each other through a clamping ring;

[0006] A counterweight ring is fixedly connected to the bottom of one of the retaining rings, and the retaining ring is made of polycarbonate.

[0007] By adopting the above technical solution, since the bottom of the drilling rig is provided with a mounting head and a protection mechanism, the protection mechanism can effectively block the flying fragments and protect the operator from being injured.

[0008] Furthermore, a mounting hole is provided on the outer side of one of the retaining rings, a water spray head is installed inside the mounting hole, a hose is provided on the outer side of the water spray head, and the hose is connected to an external water pumping device.

[0009] By adopting the above technical solution, since a mounting hole is opened on the outer side of one of the retaining rings, a water spray head is installed inside the mounting hole, and the water spray head can be effectively installed through the mounting hole.

[0010] Furthermore, the adjustment mechanism includes a base, an adjustment rod is provided on the outer surface of the base, and an adjustment seat is provided on the top of the base.

[0011] By adopting the above technical solution, since the adjustment mechanism includes a base, an adjustment rod is provided on the outer surface of the base.

[0012] Furthermore, a mounting seat is installed on the top of the adjustment seat, and the mounting seat is detachably connected to the clamping mold.

[0013] By adopting the above technical solution, since the mounting seat is installed on the top of the adjustment seat, the fixture can be installed through the mounting seat.

[0014] Furthermore, a drill rod is provided at the bottom of the mounting head, and the drill rod is made of high-speed steel.

[0015] By adopting the above technical solution, the drill rod is connected to the bottom of the bench drill through the mounting head. This design makes the replacement and maintenance of the drill rod convenient and quick. When the drill bit needs to be replaced or the drill rod needs to be repaired, the drill rod can be removed from the bench drill by simply loosening the mounting head, thereby improving work efficiency.

[0016] Furthermore, there are two water spray heads, which are mirror-imaged along the width center line of the base, and the water spray heads are obliquely arranged.

[0017] By adopting the above technical solution, the two water spray heads are arranged in a mirror image, which can cool the drill bit more evenly and prevent the drill bit from being worn or damaged due to high temperature.

[0018] Furthermore, a linear motor is provided at the rear end of the base, and an output end of the linear motor is connected to the drilling rig.

[0019] By adopting the above technical solution, since a linear motor is arranged at the rear end of the base, the drilling rig can be driven to move by the linear motor.

[0020] Furthermore, the plurality of retaining rings are arranged from small to large from top to bottom.

[0021] By adopting the above technical solution, multiple retaining rings can be effectively folded.

[0022] Furthermore, the entire material of the adjustment mechanism is stainless steel, and the base is detachably connected to the external workbench via bolts.

[0023] By adopting the above technical solution, the stainless steel material has excellent corrosion resistance and can resist the erosion of common industrial liquids such as water, oil, and cutting fluid. This enables the adjustment mechanism to work stably for a long time in a harsh working environment with humidity, oil or other corrosive substances.

[0024] Furthermore, the linear motor and the processing drill are both electrically connected to an external controller.

[0025] By adopting the above technical solution, the linear motor and the processing drill can be effectively started through an external controller.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model sets a protection mechanism. Before operation, the installation ring can be installed inside the installation groove by rotating. Then, multiple retaining rings will be connected to each other by the clamping rings and gradually expand downward, and supported downward by the counterweight ring. Through the above arrangement, during the drilling process, material fragments may splash due to the high-speed rotation of the drill bit, and the retaining ring can effectively block these splashing fragments to protect the operator from injury. The existence of the counterweight ring makes the retaining ring more stable and can maintain its position even at high-speed rotation, thereby reducing the risk of accidental injury caused by operating errors or equipment failures. In addition, the retaining ring can prevent the operator's hands or other tools from accidentally contacting the rotating drill bit, thereby avoiding interference with the processing process and helping to improve the processing accuracy. At the same time, since the retaining ring is made of polycarbonate, the retaining ring has high transparency, good mechanical strength, strong impact resistance, and high heat resistance, which can help users observe and is not easy to be damaged;

[0028] 2. The utility model can ensure that the water spray head is always aligned with the position of the drill bit by providing the mounting hole, the water spray head and the hose, effectively cool the drill rod, and prevent the drill bit from being worn or damaged due to high temperature. Moreover, the combined design of the retaining ring and the water spray head can reduce operation interruptions because the operator does not need to frequently move or adjust the equipment to clean the work area or cool the drill bit.
