Description

Technical Field

[0001] The utility model relates to the field of deep hole drills, in particular to a deep hole drill with a guiding structure. Background Art

[0002] During the drilling process of traditional deep hole drills, due to the relatively long drill rod itself, the lack of an effective guiding mechanism is another significant problem of existing deep hole drills. During the high-speed rotation and feeding process of the long drill rod, the drill rod is prone to shaking due to loss of stability, which further exacerbates the drilling deviation and reduces the machining accuracy.

[0003] A deep hole machining guiding structure of a deep hole drill boring machine provided by the existing patent CN208083516U guides and supports the deep hole drill by passing one end of the boring rod through the oil feeder. However, there is a lack of guiding during the insertion process. It is difficult for the long rod body to maintain accurate positioning when inserted into the workpiece, and it is prone to deviation, requiring continuous manual adjustment, which brings inconvenience during assembly.

[0004] Secondly, if the chips and coolant generated during the deep hole machining process cannot be discharged in time, they will accumulate in the drilling area, affecting the machining efficiency and quality. Existing deep hole drills often have deficiencies in chip removal design, resulting in chip accumulation and coolant accumulation on the table, increasing the cleaning workload and machining difficulty. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology, the purpose of the utility model is to provide a deep hole drill with a guiding structure, and solve the following technical problems: how to improve the drilling accuracy and stability, and how to optimize chip removal and coolant management.

[0006] In order to solve the problems of the existing technology, the technical solution of the utility model is as follows:

[0007] A deep hole drill with a guiding structure includes a drill handle, a drill rod and a support seat. One side of the drill handle is fixed with the drill rod, and the support seat is arranged outside the drill rod. The characteristic is that a rotating block is rotatably connected inside the support seat. A guiding groove is opened on one side of the rotating block, and a positioning hole is opened on the other side of the rotating block. The guiding groove is communicated with the positioning hole, and a chip collecting hopper is arranged on one side of the support seat.

[0008] Preferably, the shape of the positioning hole matches the shape of the drill rod, ensuring that the drill rod can be accurately inserted into the positioning hole to achieve stable support and positioning. The matching shape reduces shaking and deviation, and improves the drilling accuracy and stability.

[0009] Preferably, the inner diameter of the guiding groove gradually increases from one end close to the positioning hole to the other end, enabling the drill pipe to gradually adjust its direction during insertion and smoothly enter the positioning hole. This helps reduce the resistance during insertion, prevent hard collisions between the drill pipe and the rotating block, thereby protecting the drill pipe and the rotating block and extending their service life.

[0010] Preferably, a guiding beam protrudes downward in the center at the top of the guiding groove, enhancing the guiding effect of the guiding groove, especially when there are chip removal grooves or special shapes on the surface of the drill pipe.

[0011] Preferably, sliding cylinders are fixedly connected to the inner parts of the two corners at the top of the support base. The sliding cylinders facilitate the sliding connection of the support base to other components, allowing the support base to be finely adjusted along the direction of the drill pipe when needed.

[0012] Preferably, a flaky extension ring extends outward from the rim on the side of the chip hopper away from the support base. The extension ring increases the opening area of the chip hopper, enabling it to better capture and collect the debris and coolant generated during the drilling process.

[0013] Preferably, a diversion pipe is connected to the bottom of the chip hopper. The diversion pipe enables the debris and coolant collected in the chip hopper to be smoothly discharged, avoiding blockage and overflow of the chip hopper.

[0014] Preferably, an external thread is provided on the outer side of one end of the diversion pipe. The external thread facilitates the connection of the diversion pipe to other collection devices or processing systems.

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] 1. Through the gradually expanding design of the guiding groove and the presence of the guiding beam in the present utility model, a smooth insertion path and stable guiding effect are provided for the drill pipe. The drill pipe is used to insert into the positioning hole, and the support base and the rotating plate support during the rotation of the drill pipe, ensuring the precise positioning and stable support of the drill pipe during the drilling process, reducing the processing errors caused by shaking or deviation, and significantly improving the drilling accuracy.

[0017] 2. The combined use of the chip hopper and the diversion pipe timely discharges the waste generated during the drilling process and guides it to the designated collection device, keeping the working environment clean and tidy, reducing the adverse effects of debris on the equipment and processing quality, reducing the safety hazards caused by debris splashing and coolant splashing, and improving the working comfort and safety of the operator.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] The deep hole drill with a guiding structure has a drill shank 1, a drill rod 2, and a support base 3;

[0025] As Figures 1 to 4 shown, a drill rod 2 is fixed to one side of the drill shank 1, the support base 3 is arranged outside the drill rod 2, a rotating block 4 is rotatably connected inside the support base 3, a guiding groove 5 is formed on one side of the rotating block 4, a positioning hole 6 is formed on the other side of the rotating block 4, the guiding groove 5 communicates with the positioning hole 6, and a chip pocket 7 is arranged on one side of the support base 3;

[0026] The deep hole drill mainly consists of a drill shank 1, a drill rod 2, and a support base 3. A drill bit is installed at the end of the drill rod 2 for actual drilling operations, and the drill rod 2 is responsible for transmitting the rotation and feed force of the drill bit into the workpiece;

[0027] The support base 3 is installed outside the drill rod 2, and its position can be adjusted along the direction of the drill rod 2 as needed. The rotating block 4 rotatably connected inside the support base 3 is responsible for the precise support and positioning of the drill rod 2;

[0028] A guiding groove 5 is designed on one side of the rotating block 4 to guide the insertion of the drill rod 2. When the drill rod 2 is inserted into the positioning hole 6, the guiding effect of the guiding groove 5 ensures that the drill rod 2 can accurately and smoothly enter the predetermined position;

[0029] During the drilling process, the chip pocket 7 closely adheres to the surface of the workpiece to ensure that all the chips and coolant generated in the drilling area can be timely collected and introduced into the chip pocket.

[0030] As Figures 1 to 4 shown, the shape of the positioning hole 6 matches the shape of the drill rod 2. The matching shape reduces the shaking and deviation, and improves the drilling accuracy and stability.

[0031] As Figures 1 to 4As shown, the inner diameter of the guiding groove 5 gradually increases from one end close to the positioning hole 6 to the other end, forming a conical or gradually expanding shape to better guide the insertion of the drill pipe 2.

[0032] As Figures 1 to 4 shown, a guiding beam 8 protrudes downward and arches at the center of the top of the guiding groove 5. The guiding beam 8 can fit the chip removal groove on the surface of the drill pipe 2, enhancing the guiding stability of the drill pipe 2.

[0033] As Figures 1 to 4 shown, sliding cylinders 9 are fixedly connected to the inner parts of the two corners at the top of the support base 3.

[0034] As Figures 1 to 4 shown, a flaky extension ring 10 extends outward from the rim on the side of the chip collecting hopper 7 away from the support base 3, increasing the opening area of the chip collecting hopper 7 so that it can more effectively capture the debris and coolant generated in the drilling area.

[0035] As Figures 1 to 4 shown, a diversion pipe 11 is connected to the bottom of the chip collecting hopper 7. All the debris and coolant generated in the drilling area can be timely collected and introduced into the chip collecting hopper 7. Subsequently, these wastes are discharged through the diversion pipe 11 at the bottom of the chip collecting hopper 7, achieving the cleaning and tidying of the working environment.

[0036] As Figures 1 to 4 shown, an external thread is provided on the outer side of one end of the diversion pipe 11, facilitating the connection of the diversion pipe 11 with other collecting devices, thereby realizing the unified treatment of the wastes.
