Description

Technical Field

[0001] This utility model relates to the field of mechanical processing and manufacturing technology, specifically to a novel countersink mounting structure. Background Technology

[0002] Carbide countersinks, also known as carbide countersinks, are composed of a hard phase (WC) and a binder phase (Co). They can be used to machine the end faces of holes, creating planar, cylindrical, conical, and other profiles. Carbide countersinks typically have a steel body and a carbide tip, playing a crucial role in automotive internal combustion engine manufacturing. Depending on the machining application, countersinks can be categorized into planar countersinks, cylindrical countersinks, conical countersinks, and end-face countersinks. The most common type, the flat-bottomed countersink, has 3-4 teeth on both the circumference and the end face. A guide post is inserted into the pre-machined hole to control the coaxiality error between the countersinked hole and the original hole. The guide post is usually detachable to facilitate the manufacturing and sharpening of the end-face teeth of the countersink.

[0003] Existing technologies have the following problems: When installing a countersink, workers need to use multiple tools to disassemble the countersink mounting structure sequentially to replace the countersink. Due to the complexity of the disassembly process, new employees cannot immediately operate the equipment, leading to increased training costs. Furthermore, traditional countersink mounting structures have limited effectiveness in securing the countersink. When the countersink rotates at high speed or is subjected to significant force, it is prone to loosening or falling off. This not only affects machining accuracy but may also pose safety hazards to operators and equipment. Utility Model Content

[0004] To solve the above-mentioned technical problems, a new type of countersink mounting structure is provided, which solves the problems of complex countersink replacement steps and the easy loosening or falling off of countersinks.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel countersink mounting structure includes a connecting rod for connecting to the countersink. A sleeve is fitted onto the outer surface of the connecting rod, and the sleeve abuts against the connecting rod. The outer surface of the connecting rod has several insertion slots distributed circumferentially about the center line of the connecting rod. A fixing component is fixedly installed inside the sleeve corresponding to each insertion slot. The fixing component has a moving groove and an insertion rod inside. A rotating groove is provided inside the sleeve corresponding to each moving groove. A connecting plate is provided inside the rotating groove. Two arc-shaped plates are fixedly installed on the side of the connecting plate, and the insertion rod is located between the two arc-shaped plates.

[0007] Preferably, the fixing component includes a main body, the main body has a movable groove inside, a guide rod is fixedly installed on the inner wall of the movable groove, a sliding plate is provided inside the movable groove, an insertion rod is fixedly installed on the side of the sliding plate away from the guide rod, a spring is sleeved on the outer surface of the guide rod, and the two ends of the spring are fixedly connected to the inner wall of the movable groove and the sliding plate, respectively.

[0008] Preferably, the outer surface of the sleeve is provided with a connecting pipe, the connecting pipe is fixedly connected to several connecting plates, the outer surface of the sleeve corresponding to the connecting pipe is provided with a connecting groove, and a ring is fixedly installed on the inner wall of the sleeve corresponding to the connecting groove, the ring being slidably connected to the connecting groove.

[0009] Preferably, a limiting plate is fixedly installed on the side of the arc-shaped plates that are close to each other, and a limiting groove is formed on the lower surface of the limiting plate corresponding to the insertion rod.

[0010] Preferably, the limiting groove and the insertion rod are interference fit, and the fit tolerance is 1mm-2mm.

[0011] Preferably, the outer surface of the connecting pipe is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are circumferentially distributed about the center line of the connecting pipe.

[0012] Preferably, the end of the insertion rod away from the slide plate is provided with a dome.

[0013] Compared with the prior art, the advantages of this utility model are as follows: By setting up a fixing component, an arc plate, and a connecting pipe, when changing the countersink, the operator only needs to fix the connecting pipe. Then, by controlling the forward and reverse rotation of the entire sleeve, the length of the arc plate pushing the sliding plate is controlled, thereby controlling the fixing and unlocking of the connecting rod. Since the installation steps are not complicated, even new employees can complete the replacement of the countersink independently, thus saving training costs. At the same time, during the processing of the countersink, when the sleeve just starts to rotate, the initial velocity of the connecting pipe is zero, which makes the connecting plate on the connecting pipe fit tightly with the rotating groove, making the combination of the limiting groove and the insertion rod tighter. This makes the connecting rod more stably fixed in the sleeve when the countersink is processing the workpiece, thereby ensuring processing accuracy and reducing the probability of loosening or falling off.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Reference Figure 1-5 As shown, a novel countersink mounting structure includes a connecting rod 1 for connecting to the countersink. A sleeve 2 is fitted onto the outer surface of the connecting rod 1, and the sleeve 2 abuts against the connecting rod 1. Several insertion slots 3 are formed on the outer surface of the connecting rod 1, circumferentially distributed about the center line of the connecting rod 1. A fixing component 4 is fixedly installed inside the sleeve 2 corresponding to the insertion slot 3. The fixing component 4 fixes the connecting rod 1 inside the sleeve 2, thereby fixing the countersink inside the equipment. The fixing component 4 has a moving groove 9 and an insertion rod 12 inside. A rotating groove 5 is formed inside the sleeve 2 corresponding to the moving groove 9. The connecting plate 6 has two arc-shaped plates 7 fixedly installed on its side. The insertion rod 12 is located between the two arc-shaped plates 7. The sleeve 2 rotates to drive the connecting rod 1 fixed inside the sleeve 2 to rotate, thereby causing the countersink to rotate. When the sleeve 2 rotates as a whole, the arc-shaped plates 7 and the connecting plate 6 are subjected to centrifugal force, causing the connecting plate 6 to fit tightly against the inner wall of the rotating groove 5, thereby further fixing the connecting rod 1 to the fixing component 4. When the countersink is removed, the sleeve 2 is reversed, and the entire sleeve 2 rotates, causing the arc-shaped plates 7 to move relative to the insertion rod 12 inside the fixing component 4, thereby allowing the connecting rod 1 to move inside the sleeve 2.

[0022] like Figure 4As shown, the fixing component 4 includes a main body 8, with a movable groove 9 inside the main body 8. A guide rod 10 is fixedly installed on the inner wall of the movable groove 9. A sliding plate 11 is provided inside the movable groove 9. An insertion rod 12 is fixedly installed on the side of the sliding plate 11 away from the guide rod 10. A spring 13 is sleeved on the outer surface of the guide rod 10. The two ends of the spring 13 are fixedly connected to the inner wall of the movable groove 9 and the sliding plate 11, respectively. When fixing the connecting rod 1, the spring 13 pushes the insertion rod 12 on the sliding plate 11 into the insertion groove 3, thereby making the connecting rod 1 stably fixed in the sleeve 2. When the connecting rod 1 is removed, the sleeve 2 reverses as a whole. The sliding plate 11 squeezes the spring 13 under the action of centrifugal force. At the same time, the arc plate 7 pushes the sliding plate 11, thereby making the insertion rod 12 leave the insertion groove 3.

[0023] like Figure 1-5 As shown, the outer surface of the sleeve 2 is provided with a connecting pipe 14, which is fixedly connected to several connecting plates 6. The outer surface of the sleeve 2 corresponding to the connecting pipe 14 is provided with a connecting groove 15. The inner wall of the sleeve 2 corresponding to the connecting groove 15 is fixedly installed with a ring 16. The ring 16 is slidably connected to the connecting groove 15. Since the connecting pipe 14 and the sleeve 2 are not a whole, when the sleeve 2 starts to rotate, the initial velocity of the connecting pipe 14 is zero, which makes the connecting plate 6 on the connecting pipe 14 fit tightly with the rotating groove 5, thereby preventing the arc plate 7 from moving, and thus making the fixing component 4 stabilize the connecting rod 1. The connecting groove 15 and the ring 16 cooperate with each other, so that the connecting pipe 14 can rotate freely on the sleeve 2.

[0024] like Figure 1-5 As shown, limit plates 17 are fixedly installed on the sides of the arc plates 7 that are close to each other. A limit groove 18 is opened on the lower surface of the limit plate 17 corresponding to the insertion rod 12. The axial direction of the limit groove 18 coincides with the axial direction of the insertion rod 12. The inner wall of the limit groove 18 abuts against the outer surface of the insertion rod 12 to ensure that the insertion rod 12 will not move due to centrifugal force when the countersink rotates, so that the insertion rod 12 is stably placed in the insertion groove 3.

[0025] like Figure 5As shown, the limiting groove 18 and the insertion rod 12 are interference-fitted with a tolerance of 1mm-2mm. The interference fit means that the diameter of the insertion rod 12 is slightly larger than the width of the limiting groove 18. When the insertion rod 12 is pushed into the limiting groove 18, it undergoes a certain elastic deformation, ensuring a tight connection between the insertion rod 12 and the limiting groove 18. This tight connection prevents the insertion rod 12 from loosening or falling off due to vibration or external impact during the countersinking process. This ensures that the insertion rod 12 can smoothly enter the limiting groove 18 while maintaining the stability and reliability of the connection. Too small a tolerance may make it difficult to insert the insertion rod 12 or damage the limiting groove 18, while too large a tolerance may cause the connection to loosen. Because there is a certain pressure between the insertion rod 12 and the limiting groove 18, this pressure reduces the relative movement between them, thereby reducing the risk of wear and damage.

[0026] like Figure 1-3 As shown, the outer surface of the connecting tube 14 is provided with several anti-slip grooves 19. The anti-slip grooves 19 are circumferentially distributed about the center line of the connecting tube 14. The presence of the anti-slip grooves 19 significantly increases the roughness of the outer surface of the connecting tube 14, providing the operator with a better grip. When the operator needs to rotate or adjust the position of the countersink, the anti-slip grooves 19 can effectively prevent the hand from slipping, ensuring the stability and accuracy of the operation.

[0027] like Figure 4 As shown, a dome 20 is provided at the end of the insertion rod 12 away from the slide plate 11. The design of the dome 20 can effectively disperse the stress at the end of the insertion rod 12 and reduce the phenomenon of stress concentration. During the operation of the countersink, the insertion rod 12 may be subjected to various external forces. The shape of the dome 20 can make these external forces more evenly distributed at the end of the insertion rod 12, thereby reducing the risk of breakage or damage caused by stress concentration. The design of the dome 20 can also prevent the insertion rod 12 from scratching or damaging the surface of the limiting groove 18 or other connecting parts during insertion or removal.

[0028] Working principle: When installing the countersink, the connecting rod 1 enters the sleeve 2. The operator uses tools to fix the connecting tube 14. Then the sleeve 2 reverses, and the entire fixed component 4 rotates due to the reverse rotation of the sleeve 2. This causes the insertion rod 12 in the fixed component 4 to enter the limiting groove 18 and the insertion groove 3, thus fixing the connecting rod 1 in the sleeve 2. When the countersink is processing the workpiece, the initial velocity of the connecting tube 14 is zero when the sleeve 2 starts to rotate. This causes the connecting plate 6 on the connecting tube 14 to fit tightly with the rotating groove 5, making the connection between the limiting groove 18 and the insertion rod 12 even tighter, ensuring that the insertion rod 12 is stable in the insertion groove 3. When the connecting rod 1 is removed, the entire sleeve 2 reverses. The sliding plate 11 squeezes the spring 13 under the action of centrifugal force. At the same time, the insertion rod 12 leaves the limiting groove 18, and the arc plate 7 pushes the sliding plate 11, thus causing the insertion rod 12 to leave the insertion groove 3.
