Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and in particular to a slender rod processing tip that is easy to use. Background Technology

[0002] In the field of slender rod machining, the centering device plays a crucial role. Traditional centers for slender rod machining usually adopt a relatively fixed structural design, and the connection between the center and the main body is simple and difficult to operate. In actual production, as the machining tasks change, different models of centers are often required for slender rods with different specifications and precision requirements. However, the process of changing centers with traditional centering devices is extremely cumbersome, usually requiring the use of specialized tools and a lot of time for disassembly, installation, and debugging. This not only seriously affects production efficiency but also increases equipment downtime, leading to a significant increase in production costs.

[0003] Moreover, due to the lack of flexibility of traditional top-mounted equipment, in order to meet various processing needs, companies often have to purchase a large number of different types of complete top-mounted equipment, which undoubtedly increases equipment procurement costs, inventory management costs and equipment maintenance costs.

[0004] Furthermore, when some traditional centers need to be replaced after prolonged use due to wear or decreased accuracy, their complex structure may lead to the scrapping of the entire center device, further increasing the economic burden on enterprises.

[0005] Therefore, how to provide a slender rod machining tip that is easy to use and can reduce the overall cost of use is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a slender rod machining tip that is easy to use. This invention allows for quick assembly and disassembly of the tip and the main body, enabling rapid replacement of tips of different sizes for installation and use. It also allows for quick replacement of the tip when it wears out, thus solving the problems of inconvenient replacement and high cost of existing machining tips.

[0007] A user-friendly slender rod machining tip according to an embodiment of the present invention includes a body and a tip.

[0008] The main body has an insertion hole at its top, and a connecting shaft is integrally formed at the bottom of the top. An adjustment knob is rotatably installed on the bottom inner side of the main body. A screw is fixedly installed at the center of the top of the adjustment knob. A sleeve is fixedly installed inside the main body above the adjustment knob. An adjustment rod is movably installed inside the sleeve. The screw is screwed into the adjustment rod. A support is fixedly installed at the top of the adjustment rod. A sliding groove is opened at the top of the support. Movable seats are symmetrically slidably installed on both sides of the sliding groove. Movable arms are movably installed in both sets of movable seats via a rotating shaft. Rotating shaft seats are symmetrically installed inside the main body on both sides of the movable arms. The middle part of the movable arm is movably installed in the rotating shaft seat via a rotating shaft. A limit slider is installed on the inner side of the top of the movable arm. A limit groove is opened on the outer wall of the connecting shaft. The limit slider is inserted into the limit groove.

[0009] Furthermore, a tray is fixedly installed inside the upper part of the main body, and the connecting shaft is placed on the tray. The surface of the tray is smooth and flat, which can effectively support the connecting shaft and reduce its wear when it is not in operation. The tray also plays a certain role in cushioning, which can reduce damage to the internal structure of the main body when the tip is subjected to external impact.

[0010] Furthermore, a T-shaped slider is provided at the bottom of the movable seat, and the slide groove is a T-shaped slide groove that matches the T-shaped slider. This structural design makes the sliding of the movable seat within the slide groove more stable, preventing derailment and ensuring the reliability of the entire device.

[0011] Furthermore, an adjustment port is provided on the lower front side of the main body, through which the adjustment knob passes. This allows the operator's fingers or tools to easily access and operate the adjustment knob.

[0012] Furthermore, the outer wall of the adjustment knob is provided with several sets of anti-slip grooves. The grooves can effectively increase the friction between the hand and the adjustment knob, so that the adjustment knob can be turned easily even when the hands are sweaty or oily.

[0013] Furthermore, a tapered connecting handle is fixedly installed at the bottom of the main body. The taper of the tapered connecting handle conforms to industry standards, enabling it to fit tightly with the connection parts of various processing equipment, ensuring the secure installation of the entire tip device on the equipment and preventing loosening during high-speed rotation.

[0014] Furthermore, a threaded hole is provided at the bottom of the adjusting rod, and the thread on the outer wall of the screw meshes with the thread on the inner wall of the threaded hole. This threaded engagement enables efficient force transmission, converting the rotational motion of the adjusting knob into the linear motion of the adjusting rod. Moreover, the threads are less prone to wear during long-term use, ensuring the durability of the adjusting function.

[0015] Furthermore, the connecting shaft is inserted into the insertion hole, and the tip portion is positioned outside the main body. The fit clearance between the connecting shaft and the insertion hole is extremely small, ensuring accurate axial positioning of the tip.

[0016] The beneficial effects of this utility model are:

[0017] This invention utilizes the lifting and lowering of an adjusting rod to drive the rotation of a movable arm, thereby enabling the insertion and removal of the limiting slider and the limiting groove. This makes the replacement of the center point extremely convenient. When the center point needs to be replaced, the operator does not need to use complex tools or perform cumbersome disassembly steps; simply turning the adjusting knob is sufficient to easily pull out and insert the center point. This significantly shortens equipment maintenance time, improves the overall operating efficiency of the production equipment, and reduces equipment downtime caused by center point replacement. This is of great significance for improving production continuity and capacity. Furthermore, it can produce center points of various diameters for backup, allowing for quick switching between different sizes of center points as needed, greatly improving its applicability. Since each small center point has a different model, when dealing with slender rods of different specifications and processing requirements, there is no need to purchase multiple sets of complete processing center point devices; only the corresponding model of center point needs to be replaced, greatly reducing the overall operating cost.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figure 1-4 A user-friendly slender rod machining tip includes a body 1 and a tip 3. The body 1 is made of a high-strength and rigid metal material, such as high-quality alloy steel, to ensure that it can withstand various forces during machining and maintain a stable structural shape.

[0026] The main body 1 has an insertion hole 16 on the top. The inner diameter of the insertion hole 16 is precision machined to ensure that the connecting shaft 19 at the bottom of the tip 3 can be tightly fitted when inserted, reducing the fit gap and thus effectively improving the axial positioning accuracy of the tip during operation.

[0027] The bottom of the tip 3 is integrally formed with a connecting shaft 19, which is inserted into the insertion hole 16. The tip 3 is located outside the main body 1. The tip 3 is made of high hardness and high wear resistance material, such as hard alloy or high-quality steel that has undergone special heat treatment. Its exposed part is finely ground and has a very high surface finish. This can effectively reduce frictional resistance when in contact with the slender rod and ensure accurate positioning and support of the slender rod, ensuring that the surface quality and dimensional accuracy of the processed slender rod meet the requirements.

[0028] The bottom of the main body 1 is fixedly equipped with a tapered connecting handle 2. The taper of the tapered connecting handle 2 is designed and processed according to international or industry standards, such as Morse taper or other specific standard tapers. The entire tip device can be connected to the corresponding processing equipment or workbench through the tapered connecting handle 2. When connecting, a suitable fastening method is used, such as nut fastening or hydraulic clamping device, to ensure the firmness and reliability of the connection. There will be no loosening under high-speed rotation and large cutting force.

[0029] The main body 1 has an adjustable knob 4 that can be rotatably installed on the bottom inner side. The adjustable knob 4 is made of engineering plastic or metal material with anti-slip treatment to increase the friction between the operator's hand and the knob, making it easy to operate.

[0030] An adjustment port 18 is provided on the lower front side of the main body 1. The edges of the adjustment port 18 are rounded, which not only prevents the operator from being scratched during operation, but also makes the operating space more open, allowing the operator's fingers or tools to easily reach the adjustment knob 4. The adjustment knob 4 passes through the adjustment port 18, and the outer wall of the adjustment knob 4 has several sets of anti-slip grooves. The shape of the grooves can be designed as ring, straight, or other reasonable shapes, with a depth generally between 0.5-1.5 mm and a width between 2-5 mm. This design can effectively increase the friction between the operator's hand and the adjustment knob, so that the operator can easily turn the adjustment knob 4 even when their hands are sweaty or oily. A screw 12 is fixedly installed at the center of the top of the adjustment knob 4. The screw 12 is made of high-strength alloy steel, and its thread precision reaches a high level, such as 6g or 7h precision grade. The pitch is set between 0.5-2 mm according to the actual adjustment needs, enabling fine adjustment.

[0031] A sleeve 5 is fixedly installed inside the main body 1 and above the adjusting knob 4. The sleeve 5 is fixedly connected to the inner wall of the main body 1 by welding or precision assembly to ensure its positional stability. An adjusting rod 6 is movably installed inside the sleeve 5. The gap between the inner diameter of the sleeve 5 and the outer diameter of the adjusting rod 6 is controlled between 0.05-0.15 mm to ensure that the adjusting rod 6 can slide smoothly up and down inside the sleeve 5 without significant shaking.

[0032] The bottom of the adjusting rod 6 has a screw hole 17. The thread on the outer wall of the screw 12 meshes with the thread on the inner wall of the screw hole 17. When the adjusting knob 4 is turned, the screw 12 rotates accordingly. Due to the screw connection between the screw 12 and the adjusting rod 6, the adjusting rod 6 will move up and down inside the sleeve 5.

[0033] In order to ensure the smoothness and straightness of the movement of the adjusting rod 6 during its up and down movement, a guide keyway can be provided on the inner wall of the sleeve 5, and a guide key is provided at the corresponding position on the outer wall of the adjusting rod 6. The guide key and the guide keyway are fitted with a clearance, and the clearance is generally between 0.03-0.1 mm.

[0034] Secondly, a support 7 is fixedly installed on the top of the adjusting rod 6. The support 7 is made by casting or forging and has sufficient strength and rigidity. A groove 8 is opened on the top of the support 7. A movable seat 9 is symmetrically slidably installed on both sides of the groove 8. A T-shaped slider is set at the bottom of the movable seat 9. The groove 8 is a T-shaped groove that matches the T-shaped slider. The dimensional tolerance of the T-shaped slider is controlled between ±0.03-±0.08 mm. The dimensional tolerance of the T-shaped groove matches it. In addition, the inner wall of the groove 8 is ground and the surface roughness can reach Ra0.4-Ra0.8 micrometers. This structure allows the movable seat 9 to slide stably left and right in the groove 8 with low sliding resistance and ensures that it will not derail when subjected to a certain lateral force.

[0035] Both sets of movable seats 9 have movable arms 11 mounted on them via pivots. These pivots are made of high-precision cylindrical pins or specially designed shaft parts with high surface hardness, and are hardened and ground. The connection points with the movable seats 9 and movable arms 11 use transition fits or interference fits to ensure tight connection and flexible rotation. Inside the main body 1, symmetrical pivot seats 10 are mounted on both sides of the movable arms 11. The pivot seats 10 are fixed inside the main body 1 by welding or bolting, and their installation positions are precisely measured and adjusted to ensure that the movable arms 11 can rotate flexibly within a predetermined angle range after installation. The middle of the movable arm 11 is movably mounted within the pivot seat 10 via a pivot. A limit slider 15 is installed on the inner top of the movable arm 11. The limit slider 15 is made of wear-resistant metal material, such as hardened steel or nitrided steel, and its shape matches the limit groove 13 opened on the outer wall of the connecting shaft 19. The limit slider 15 is inserted into the limit groove 13. The depth of the limiting slide groove 13 is generally between 3-8 mm and the width is between 2-5 mm. The dimensional tolerance of the limiting slider 15 is controlled between -0.05 and +0.05 mm to ensure a tight fit between the two and prevent radial displacement of the connecting shaft 19 during operation.

[0036] It should be noted that a tray 14 is fixedly installed inside the upper part of the main body 1. The tray 14 is made of a material with certain elasticity and wear resistance, such as rubber or a composite material of polyurethane wrapped metal plate. The connecting shaft 19 is placed above the tray 14.

[0037] The tray 14 serves to support the connecting shaft 19. When the tip 3 is subjected to a slight external impact or in a non-working state, the tray 14 can effectively buffer the impact force of the connecting shaft 19 on the main body 1, reducing wear and damage. At the same time, the tray 14 also plays a certain role in assisting the positioning and stabilization of the tip 3. Its surface in contact with the connecting shaft 19 can be designed to be arc-shaped or flat, and a suitable shape can be selected according to actual needs to better fit the bottom contour of the connecting shaft 19.

[0038] In actual use, when the tip 3 needs to be replaced, the operator first places their hand or operating tool on the adjusting knob 4 and rotates the adjusting knob 4 in the predetermined direction. The rotation of the adjusting knob 4 drives the screw 12 to rotate synchronously. Due to the thread engagement between the screw 12 and the screw hole 17 of the adjusting rod 6, the rotational motion of the screw 12 is converted into the linear motion of the adjusting rod 6. The adjusting rod 6 will rise or fall axially within the sleeve 5. If the tip 3 needs to be pulled out at this time, the adjusting knob 4 is rotated to raise the adjusting rod 6. The rise of the adjusting rod 6 will drive the support 7 and its movable seat 9 to move upward together. Since the movable seat 9 is connected to the movable arm 11 through a rotating shaft, and the middle of the movable arm 11 is movably connected to the rotating shaft seat 10, when the movable seat 9 moves upward, the movable arm 11 will open outward around the rotating shaft seat 10. This rotation process is a continuous and smooth process. The limiting slider 15 on the inner side of the top of the movable arm 11 will gradually move with the rotation of the movable arm 11. The connecting shaft 19 is gradually pulled out from the limiting groove 13. When the limiting slider 15 is completely pulled out from the limiting groove 13, the connecting shaft 19 loses its radial constraint. At this time, the tip 3 can be easily pulled out upwards. When the tip 3 needs to be inserted, first align the connecting shaft 19 of the tip 3 with the insertion hole 16 of the main body 1 and insert it. Then turn the adjustment knob 4 to make the adjustment rod 6 move downwards. The adjustment rod 6 drives the support 7 and the movable seat 9 to move downwards. At this time, under the pressure of its own weight and the connecting shaft 19, the movable arm 11 will rotate inwards around the rotating shaft seat 10, pulling the top of the two sets of movable arms 11 to move inwards, so that the limiting slider 15 is inserted into the limiting groove 13 to complete the limiting and fixing of the connecting shaft 19. At this time, the connecting shaft 19 cannot be pulled out, so the tip 3 cannot be pulled out either. This realizes the quick replacement and reliable fixing of the tip 3, which greatly improves the production efficiency and operation convenience in the processing of slender rods, and at the same time reduces the cost increase caused by the inconvenience of tip replacement.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
