Description

Technical Field

[0001] This utility model relates to the field of machining holes and grooves, and in particular to a composite hole and groove integrated machining and forming device. Background Technology

[0002] In the field of workpiece structure processing, in order to meet complex functional requirements, it is usually necessary to prepare composite holes and grooves with specific geometric shapes on the surface of the workpiece. Such structures usually require first machining a central positioning hole with a drilling device, and then performing secondary processing such as annular grooves around the central hole with a grooving device. This requires multiple layers of processing, resulting in low production efficiency, poor precision, and difficulty in ensuring the concentricity of the holes and grooves. Utility Model Content

[0003] To overcome the problems of low efficiency and low precision in composite hole and groove processing that require multiple layers in the background technology, this utility model provides a composite hole and groove integrated processing and forming device. By using the guide drilling part and the grooving part together, the workpiece can be grooved at the same time as drilling, realizing one-time processing and forming. Moreover, the two are stably connected through a combination of various structures, which has the beneficial effects of reducing processing steps, improving production efficiency, high product precision, high coaxiality, strong connection stability between components, and good reliability.

[0004] The technical solution of this utility model is as follows: A composite hole and groove integrated machining and forming device includes a guide drilling component and a grooving component. The grooving component is inserted into the guide drilling component, and the machining ends of both components rotate simultaneously to machine the composite hole and groove of the workpiece.

[0005] Preferably, the guide drilling component is integrally formed and includes a connecting part, a mounting part and a drill bit connected sequentially from top to bottom. The mounting part has a mounting through hole, and the slotted component is inserted into the mounting through hole.

[0006] More preferably, the guide drilling component has a cylindrical structure, and a snap-fit ​​block connects the mounting through hole and the drill bit, with the slotted component bridging the snap-fit ​​block.

[0007] More preferably, the drill bit is made of 40Cr material and is manufactured through rough machining and heat treatment.

[0008] In a further preferred embodiment, the bottom of the slotted component has a snap-fit ​​groove, which snaps into the snap-fit ​​block, and the slotted component is perpendicularly connected to the snap-fit ​​block.

[0009] In a further preferred embodiment, the cutting edge at the bottom of the slotted part is symmetrically arranged on both sides of the snap-fit ​​groove, and the cutting edge cooperates with the annular groove structure to be opened on the workpiece.

[0010] A further preferred embodiment includes a positioning sleeve, with the guide drilled part passing downward through the positioning sleeve, and the upper part of the slotted part being engaged in a slot on the bottom surface of the positioning sleeve, the slot and the engagement groove being arranged perpendicularly.

[0011] In a further preferred embodiment, the guide drilling component, the slotted component, and the positioning sleeve are coaxially connected, and the positioning sleeve is also provided with a screw hole, through which the fastening bolt passes and abuts against the guide drilling component.

[0012] In a further preferred embodiment, the connecting part of the guide drilling component is connected to a drill rod, the connecting part extends into the drill rod and is threadedly connected to it; a fixing bolt is circumferentially sleeved at the bottom of the drill rod, and the fixing bolt tightens the positioning sleeve onto the slotted component.

[0013] More preferably, the top of the drill rod is connected to a drill shank via a thread, and the drill shank is connected to the output end of the power equipment on the drilling machine.

[0014] Compared with existing technologies, the advantages of the above technical solution are as follows: By using guide drilling components and slotting components together, slotting can be performed on the workpiece simultaneously with drilling, achieving one-time processing. The hole and slot processing dimensions are highly accurate and coaxial. Furthermore, the combination of slot-shaped fixing, bolt connection, and clamping structure effectively enhances the connection stability between components, further improving processing accuracy and coaxiality. This results in improved production efficiency, high product precision and coaxiality, simple operation, easy device manufacturing, low cost, and strong practicality. The slotted part is inserted into the mounting through hole, which can restrict the relative rotation of the slotted part and the guide drilled part as a whole. The snap-fit ​​groove is snapped onto the snap-fit ​​block, which further restricts the relative rotation at the connection point. The two connection methods are used together to improve the radial connection stability of the slotted part and the guide drilled part, and the two can rotate stably and synchronously.

[0015] The slotted part is snapped into the slot of the positioning sleeve, which further restricts the relative rotation of the slotted part and the guide drilling part in the radial direction, making both of them more stable to process.

[0016] The drill rod is internally fixedly connected to the guide drilling component via a threaded connection, while externally, the positioning sleeve is tightened onto the slotted component via fixing bolts. This not only provides stable transmission to the guide drilling component but also works with the positioning sleeve to restrict the axial movement of the slotted component.

Detailed Implementation To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Example 1: As Figures 1 to 8 The device shown is a composite hole and groove integrated processing and forming device, which includes a guide drilling component 1 and a grooving component 2. The grooving component 2 is inserted into the guide drilling component 1, and the processing ends of both are rotated simultaneously to process the composite hole and groove of the workpiece 5.

[0020] Therefore, by using the guide drilling component 1 and the slotting component 2 together, the workpiece 5 can be slotted at the same time as drilling, achieving one-time processing and ensuring the dimensional accuracy and coaxiality of the hole and slot. This has the technical effect of improving production efficiency and achieving high product accuracy and coaxiality. Example 2: Based on Example 1, the guide drilling component 1 is optimized and includes a connecting part 11, a mounting part 12, and a drill bit 13 connected sequentially from top to bottom. The mounting part 12 has a mounting through hole 121, and the slotted component 2 is inserted into the mounting through hole 121. The guide drilling component 1 is generally cylindrical, and the mounting through hole 121 is a square hole formed by drilling through the middle of the mounting part 12, the width of which matches the width of the slotted component 2.

[0021] Preferably, a retaining block 14 connects the mounting through hole 121 and the drill bit 13. The retaining block 14 is a rectangular structure, with its top surface fixed to the port of the mounting through hole 121 and its bottom surface fixed to the drill bit 13. After the slotted part 2 is inserted into the mounting through hole 121, its bottom can be engaged with the two sides of the retaining block 14. The drill bit 13 has a diameter of 7.5mm, which matches the center hole to be drilled in the workpiece 5. It is made of 40Cr material and has undergone rough machining and heat treatment, making it more durable, wear-resistant, and less prone to breakage.

[0022] Example 3: Based on Example 2, the slotted component 2 is optimized. The bottom of the slotted component 2 has a snap-fit ​​groove 21, which is a rectangular groove structure that matches the width of the snap-fit ​​block 14. After the slotted component 2 passes vertically through the mounting through hole 121 in the horizontal direction, it moves vertically downwards to press the snap-fit ​​groove 21 against the snap-fit ​​block 14. Thus, the snap-fit ​​groove 21 can stably engage with the snap-fit ​​block 14, and the slotted component 2 straddles the snap-fit ​​block 14, connecting vertically to it. The slotted component 2, when snapped into the mounting through hole 121, restricts the relative rotation between the slotted component 2 and the guide drilling component 1. The snap-fit ​​groove 21, when snapped onto the snap-fit ​​block 14, further restricts the relative rotation at the connection point. The combined use of these two connection methods improves the radial connection stability between the slotted component 2 and the guide drilling component 1, allowing them to rotate stably and synchronously.

[0023] In a further preferred embodiment, the cutting edge 22 at the bottom of the slotted part 2 is symmetrically arranged on both sides of the retaining groove 21, and the structure of the cutting edge 22 matches the annular groove to be cut in the workpiece 5. The symmetrical arrangement of the cutting edge 22 on both sides of the retaining groove 21 allows the drill bit 13 of the guide drilling part 1 to pass through the center of the cutting edge 22, resulting in a hole or groove with better coaxiality and further improving machining accuracy. Furthermore, the shape of the cutting edge 22 can be adjusted according to actual conditions; for example, it can be adjusted to allow for the machining of features such as steps or bosses.

[0024] Example 4: Based on the above examples, a preferred design is provided, further including a positioning sleeve 3. The guide drill 1 passes vertically downward through the positioning sleeve 3, while the upper part of the slotted part 2 is engaged in a groove 31 on the bottom surface of the positioning sleeve 3. The arrangement direction of the groove 31 is perpendicular to the arrangement direction of the engaging groove 21. The positioning sleeve 3 is a cylindrical structure with a through hole 32 in the middle through which the guide drill 1 can pass. The engagement of the slotted part 2 in the groove 31 of the positioning sleeve 3 further restricts the radial relative rotation of the slotted part 2 and the guide drill 1, enabling stable processing of both.

[0025] Preferably, the guide drilling component 1, the slotted component 2, and the positioning sleeve 3 are coaxially connected, which can efficiently transmit torque and movement between components, ensure transmission accuracy and position control, ensure smooth operation, reduce vibration, and improve machining accuracy.

[0026] The positioning sleeve 3 is also provided with screw holes 33, and fastening bolts 34 pass through the screw holes 33 and abut against the guide drilled part 1. Among them, the mounting through hole 121 is provided in the lower part of the mounting part 12, and the fastening bolts 34 are provided in two sets, which pass through the screw holes 33 on both sides of the positioning sleeve 3 and abut against the upper part of the mounting part 12, thereby improving the connection stability between the guide drilled part 1 and the positioning sleeve 3, so that the two can rotate synchronously.

[0027] Example 5: Based on the above examples, a preferred design is made. The connecting part 11 of the guide drilling part 1 is connected to the drill rod 4. The connecting part 11 extends into the drill rod 4 and is threadedly connected to it. The bottom of the drill rod 4 is circumferentially fitted with a fixing bolt 41, which tightens the positioning sleeve 3 onto the slotted part 2.

[0028] Thus, the drill rod 4 is internally fixedly connected to the guide drilling component 1 via a threaded connection, while the externally, the positioning sleeve 3 is pressed against the slotted component 2 by the fixing bolt 41. This not only enables stable transmission of the guide drilling component 1, but also works with the positioning sleeve 3 to restrict the axial movement of the slotted component 2.

[0029] Preferably, the top of the drill rod 4 is threadedly connected to a drill shank 42, which is connected to the output end of the power equipment (such as a motor) on the drilling machine. During processing, the drill bit 13 of the guide drilling component 1 is aligned with the target point on the workpiece 5, and then the power equipment is started. The drill shank 42 drives the drill rod 4 to rotate, and the drill rod 4 transmits the rotational force to the guide drilling component 1. The rotation of the guide drilling component 1 drives the grooving component 2, and the positioning sleeve 3 rotates synchronously. Thus, drilling and grooving of the workpiece 5 can be achieved simultaneously.

[0030] When assembling this device, first, vertically pass the guide drilling component 1 through the through hole 32 of the positioning sleeve 3. Then, vertically pass the slotted component 2 through the mounting through hole 121 of the guide drilling component 1 in the horizontal direction. Next, move the slotted component 2 downward so that its locking groove 21 is aligned and pressed against the locking block 14 of the guide drilling component 1. The slotted component 2 is then stably locked with the guide drilling component 1. Then, the locking groove 31 of the positioning sleeve 3 is locked onto the slotted component 2, thus achieving a stable connection between the slotted component 2, the positioning sleeve 3, and the guide drilling component 1. Finally, tighten the fixing bolt 41 to connect the guide drilling component 1 and the drill rod 4, and then fix the drill rod 4 onto the drill shank 42 to complete the assembly process of this device. It can then be used simultaneously for drilling and slotting workpiece 5.

[0031] This device uses a combination of slotted fixing, bolt connection and clamping structure. The effective superposition of multiple connection methods greatly improves the connection stability between components and ensures the dimensional accuracy and coaxiality of the hole and slot. It has the advantages of simple operation, easy device manufacturing, low cost and strong practicality.

[0032] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the technical solution of this application, and these all fall within the scope of protection of this application.
