Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing equipment, and in particular to a self-adaptive turning chip breaking device. Background Art

[0002] High-toughness difficult-to-process materials are widely used in high-end manufacturing fields such as aircraft engines, spacecraft, and nuclear energy equipment because of their excellent mechanical properties and high-temperature resistance. However, during the turning process of these high-toughness difficult-to-process materials, such as titanium alloys and nickel-based high-temperature alloys, the chips are more difficult to break than those of general materials. The chips are entangled on the tool or workpiece, causing a series of problems such as sharp tool wear and reduced processing quality. These problems not only affect the processing quality, but also threaten the safety of the operator.

[0003] At present, the commonly used chip breaking methods mainly include: changing the parameters of the cutting fluid and adjusting the tool coating, using the method of adding special elements to the workpiece material, using chip breaking tables, chip breaking pads, chip breaking nets, etc. For the method of changing the parameters of the cutting fluid, reducing the lubricity of the cutting fluid; increasing the viscosity of the cutting fluid; adding special chip breaking components to the cutting fluid; reducing the injection pressure of the cutting fluid; increasing the injection angle of the cutting fluid and changing the injection method of the cutting fluid can all promote chip breaking. However, the use of these methods to break chips often leads to the influence of machining accuracy, aggravated tool wear, and increased machining costs. This method is rarely used on high-precision machining lines. Although the method of adding special elements to the workpiece material has a good chip breaking effect, it will increase material costs and preliminary preparation work. In addition, the method of using a chip breaking table to break chips is widely used. For example, in order to adapt to different types of processing materials, chip breaking tables of various shapes and sizes are welded on high-speed steel tools for easy selection, which is both practical and convenient. The disadvantage is that the optimization of the overall performance of the tool is limited by the chip breaking function.

[0015] Embodiment 1: See also Figures 1 to 4In an embodiment of the present invention, the self-adaptive turning chip breaking device comprises a chip breaking block 10, a shock absorbing body 13, an adjusting part 20, a gas spring hydraulic rod 30 and a bottom support connecting plate 40, wherein the adjusting part 20 comprises a push rod 21, a first screw guide rail 22, a support plate and a second screw guide rail 27, the lower part of the shock absorbing body 13 is installed and connected with the chip breaking block 10, and a micro bearing installation groove is provided above the shock absorbing body 13, the push rod 21 comprises a push rod connecting member 210 and a push rod support plate 211, the two ends of the push rod 21 are respectively fixedly connected with the upper part of the shock absorbing body 13 and the push rod connecting member 21, and the micro bearing 17 is installed at the connecting parts at both ends of the push rod 21 and fixed by bolts; the first screw guide rail 22 comprises a first screw rod 221, a guide rail bottom plate 222 and a first slide 223, and the lower end of the push rod connecting member 210 The push rod support plate 211 is connected to the first slide 223, and the support plate includes a front support plate 23, a rear support plate 24 and a bottom support plate 25. The upper ends of the front support plate 23 and the rear support plate 24 are fixedly connected to the front and rear sides of the slide rail bottom plate 222 through L-shaped connecting pieces 26, and the lower ends are connected and fixed to the bottom support plate 25 through the L-shaped connecting piece 26.

The bottom support plate 25 is connected to the second slide 272 through bolts, and the adjusting part 20 is fixed to the bottom support connecting plate 40 through bolts.

[0016] Specifically, the self-adaptive turning chip breaking device is connected to the square tool rest 50 through the bottom support connecting plate 40, and the bottom support connecting plate 40 is tightened by bolts to fix the entire device; before the lathe works, the first slide 223 slides on the first screw rod 221, driving the push rod 21 to move, and at the same time, the group of second slides 272 slides on the second screw rod 271, driving the adjustment part 20 to move forward and backward, thereby pushing the shock absorber 13 to move forward and backward.

Specifically in this embodiment, one group is 2; The second slide 272 can achieve a small sliding movement on the second screw rod 271, and the first slide 271 can achieve a large sliding movement on the first screw rod 221. Therefore, the front end of the chip breaker block 10 can use the connection point of the gas spring hydraulic rod 30 as a fulcrum and rotate around it, and through the miniature bearing 17, it can achieve up and down angle deflection to adjust its working angle; when the lathe is working, the gas spring hydraulic rod 30 will generate resistance to hinder the forward and backward movement of the chip breaker block 10. Under the joint action of the push rod 21 and the gas spring hydraulic rod 30, the chip breaker block 10 can rotate around the axis OO' (as shown in the attached figure) formed at the place where its front end fits with the front cutting edge 61 of the turning tool 60 Figure 8 The chip breaking angle is changed by rotating the tool (as shown).

[0017] Furthermore, the turning chip breaking device provided by the present invention is combined with the CNC lathe through the square tool holder 50 and integrated with the G code of the CNC lathe. Before turning processing, the most suitable chip breaking block is matched according to the chip breaking conditions proposed by Nakayama based on the input parameters such as cutting amount and material. By detecting the position and angle of the chip breaking block 10, the chip breaking block 10 is adjusted to the optimal chip breaking area and inclination angle through the coordinated action of the single-chip microcomputer, control system and actuator to achieve precise chip breaking.

[0018] like Fig. 9 As shown in the figure, based on the chip breaking conditions proposed by Nakayama, a calculation formula for the internal bending strain of the chip is provided: Where: is chip strain; is the fracture strain of the chip material; is the chip thickness; It is the curling radius of the chips after they pass through the chip breaker; It is the curling radius formed when the chip collides with the tool or workpiece before it breaks.

[0019] See also Figures 5 to 7 The chip breaker block 10 includes a waist-shaped groove 11, a metal shockproof column 12, a limiting portion 14 and a guide rod 15. The shock absorber 13 includes a first shock absorber 130 and a second shock absorber 131. The first shock absorber 130 includes a first guide sleeve 130a and a first elastic member 130b. The guide rod 15 extends into the shock absorber 13 and the first guide sleeve 130a, and abuts against the first elastic member 130b. The chip breaker block 10 is connected to the shock absorber 13 through the limiting portion 14. The waist-shaped groove 11 is provided on one side of the chip breaker block 10. A cylindrical groove 110 is provided in the waist-shaped groove 11. The metal shockproof column 12 is provided in the cylindrical groove 110. A waist-shaped sheet 1 is provided on the waist-shaped groove 11. 11, the two are fixedly connected by a pin; the second shock absorbing part 131 includes a second guide sleeve 131a, a second elastic member 131b and a support part 131c, the second shock absorbing part 131 is arranged in the middle of the shock absorbing chamber 16, and is symmetrically arranged on both sides of the first shock absorbing part 130, one end of the second elastic member 131b is in contact with the first guide sleeve 130a, and the other end extends into the guide sleeve 131a and is fixed in the support part 131c; the chip breaking block 10 is also provided with a coolant channel 132, the coolant channel 132 passes through the shock absorbing body 13 and the chip breaking block 10, and extends into the first shock absorbing part 130 and the guide rod 15, and disperses a coolant injection port 132a with the front end of the chip breaking block 10.

[0020] Specifically, in the present invention, the material of the metal shockproof column 12 is tin, and the metal shockproof column 12 can increase the weight of the chip breaker block 10, and when turning a workpiece, it can reduce the vibration generated during turning, improve the stability of turning, and improve the quality of turning. A metal shockproof column 12 is inserted into each cylindrical groove 110, which can evenly disperse the weight of the front end of the chip breaker block 12, and it is not easy to cause the phenomenon of partial weight; a limiting groove 112 is provided on the side wall of the cylindrical groove 10, and a limiting block 120 is provided on the metal shockproof column 12, and the limiting block 120 is connected with the limiting groove 112. After the metal shockproof column 12 is installed, the limiting block 120 is located in the limiting groove 112, which can reduce the shaking of the metal shockproof column 12 in the cylindrical groove 110, thereby increasing the stability of turning.

[0021] When the chip breaker block 10 is performing chip breaking work, the chip breaker block 10 interacts with the first elastic member 130b through the guide rod 15, and the first elastic member 130b is correspondingly installed with a damper to disperse and reduce the vibration caused by the front end of the chip breaker block 10 being subjected to the force of the workpiece; when subjected to large vibrations, when the interaction between the guide rod 15 and the first elastic member 130b cannot completely offset, the second shock absorbing part 131 participates in the action, through the interaction between the first guide sleeve 131a and a group of second elastic members 131b, the second elastic members 131b are also correspondingly installed with The damper offsets the vibration generated by the chip breaker block 10 when it is working. As for the number of the group of second elastic members, there is no specific restriction here, which can be selected according to actual conditions. Specifically in the present embodiment, one group has two members. In addition, in addition to the above-mentioned components, the remaining space in the shock absorbing chamber 16 is filled with elastic members (not shown in the figure) to absorb the vibration generated by the shock absorbing body 13 as a whole during operation. As for the material of the elastic member, there is no specific restriction here, which can be made of elastic materials such as latex, rubber, sponge, etc., which can be selected according to actual conditions. Specifically in the present embodiment, the elastic member is made of latex.

[0022] The coolant channel 132 opened in this embodiment is where the coolant pipe for lathe processing is set. An external coolant spraying device is connected, and the coolant flows through the coolant channel 132 and is finally sprayed to the workpiece processing location through a plurality of coolant injection ports 132a at the front end of the chip breaker block 10, so as to reduce the chip breaking temperature and flush away the broken chips.

[0023] In addition, during the operation of the chip breaker, the adjustment unit 20 can be used to perform adaptive adjustment, and the impact force F can be controlled according to the rotation speed V of the workpiece to be processed relative to the chip breaker block 10, thereby adapting to different cutting conditions. Fig.10 The specific adjustment principle is as follows: The workpiece rotates at a speed V relative to the chip breaker block 10, and the relative movement generates an impact force F, the principle of which is based on the momentum theorem: , Where: m: chip breaker mass; : Speed ​​change during collision (assuming that the speed of the chip breaker drops to 0 after collision, then =V); : Collision duration (usually microseconds, very small value).

[0024] Based on the above theorem, the key factors in the chip breaking process of the chip breaking block 10 are as follows: Speed ​​V: The greater the moving speed, the greater the impact force F.

[0025] Collision time : Determined by material hardness and contact area, the shorter the time, the greater the impact force F.

[0026] Angle correction: If the movement direction of the chip breaker 10 forms an angle α with the chip flow direction, the effective speed is Vsinα, and the formula is corrected to: The chip fracture needs to meet the stress σ generated to exceed the tensile strength of the material , where A is the cross-sectional area of ​​the chip. Combined with the impact force formula: .

[0027] Based on the above formula, the impact force F can be controlled by adjusting the rotation speed V of the workpiece to be processed relative to the chip breaker block 10, so as to adapt to different cutting conditions: when the speed V increases, the impact force F increases significantly, making the chips easier to break. In practical applications, the optimal V and .

[0028] Embodiment 2: See also Fig.10 Based on the overall structural framework of Example 1, this embodiment adds a chip breaker impactor 18 to the front end of the chip breaker block 10 on the original basis. The chip breaker impactor 18 includes a small motor 180 and a slide rail 181.

[0029] Specifically, the front end of the chip breaker impactor 18 is arc-shaped, which is conducive to the chip breaking being bent and curled at the impact point 182 when the chip is impacted by the chip breaker impactor 18. The slide rails on both sides of the chip breaker block 10 are driven by a small motor to adjust the up and down positions, thereby driving the chip breaker impactor installed on the slide rails.

[0030] The device drives the chip breaker to move at different speeds, so that the impact module generates different impact forces. After the impact force is transmitted to the cutting layer, the material fatigue effect is used to induce crack propagation inside the chip, and the chip is bent, and finally the brittle fracture of the chip is achieved, which effectively reduces the probability of continuous chip formation, reduces the occurrence rate of winding failure, and significantly improves the stability of the processing system.

[0031] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
