Description

Technical Field

[0001] The invention belongs to the technical field of worm gear milling, in particular to a worm processing technology and a gear milling device. Background Art

[0002] The worm is an important mechanical transmission element, which is often used to convert rotational motion into axial or oblique linear motion. The worm and worm wheel together constitute the worm transmission, which is widely used in various industrial fields, such as machinery manufacturing, aerospace, automobile, etc. In order to manufacture high-quality worm transmission components, worm gear milling equipment is an indispensable tool.

[0003] A patent application with publication number CN208513786U discloses a worm gear milling device, including a processing table, a gear milling mechanism arranged on the processing table, and a worm clamping mechanism. The gear milling mechanism includes a first slide rail arranged along the radial direction of the worm and a frame sliding along the slide rail. The frame is equipped with a high-speed motor for driving the milling cutter to rotate at high speed. The worm clamping mechanism includes a second slide rail arranged along the axial direction of the worm and a fixed base sliding along the slide rail. The fixed base is provided with two relatively spaced fixing parts. The two ends of the worm are respectively mounted on the two fixing parts and rotate under the drive of the rotating motor. This design avoids the problem of poor tooth shape and spiral shape accuracy caused by the radial and axial movement of the milling cutter in the traditional gear milling process.

[0004] There are still some problems in the actual application of the above scheme. When using the milling device, since the whirlwind milling machine cuts the outer surface of the round steel at a high speed, a thread with a certain inclination angle is generated on the outer surface of the round steel. However, during the cutting process of the whirlwind milling machine, due to the high cutting speed, some of the chips generated will be spattered. Some steel chips may be spattered on the guide rail. When the slider slides, the steel chips are drawn between the slider and the guide rail, thereby increasing the friction of the slider and possibly scratching the guide rail. After long-term use, the slider and the guide rail will be greatly worn, which will affect the whirlwind milling machine when cutting the round steel, causing jitter or shaking and other unstable conditions, resulting in errors in the cutting accuracy of the round steel, thereby reducing the production quality of the worm.

[0025] A worm processing process, characterized in that it comprises the following specific steps:

[0026] Step 1: The raw material of the worm gear may be steel billet or other metal billet, which is manufactured into round steel with a circular cross-section through different processes, such as rolling or drawing. The long round steel strips are then cut into specific lengths using a round cutting machine, and the cut round steel is then transferred to a multi-purpose furnace to increase the hardness and strength of the material. The round steel is then processed using a milling device, and then the gear is ground using a gear grinding machine, which can further improve the accuracy and surface finish of the gear to meet the needs of high-precision applications.

[0027] Step 2: The specific process of gear milling is to first place the round steel after round cutting in the middle of the fixed plate through the mechanical arm, and then fix one end of the round steel through the cooperation of three fixed plates. After fixing the round steel, start the hydraulic cylinder in the control panel to hold the other end of the round steel away from the fixed plate, and then start the motor to drive the whirlwind milling machine to rotate. After the whirlwind milling machine rotates, it will cut the round steel at a certain angle, so that the round steel will be added into a worm. After the worm is processed, the worm is clamped by the mechanical arm, and the three first hydraulic cylinders on the fixed plate are closed to release the round steel. Then the mechanical arm will take the round steel out, place it on the transfer platform, and then enter the gear grinding device to grind the cutting position, so that the worm can be used more stably.

[0028] Step 3: The round steel after cutting has the function of a worm. In order to enhance its performance, the worm is placed in a nitriding furnace and exposed to a high temperature and nitrogen environment. This process will form a nitrided layer on the surface of the product, improve its hardness, wear resistance and corrosion resistance, and enhance the overall performance of the product. Finally, after quality inspection, the finished product is packaged and shipped to customers.

[0029] The beneficial effects of the present invention are as follows:

[0030] 1. The worm processing technology and gear milling device described in the present invention cooperate with the set air pump and the fixed tube. No matter which direction the switch is twisted, the air pumps on both sides of the starting slider will be turned on, causing the air pumps to release high-pressure gas in an instant. The released high-pressure gas is ejected from the fixed tube, and the fixed tube is directed to one side of the slide rail, thereby achieving the effect of cleaning the slide rail. During this process, the slide rail moves at a uniform speed. Therefore, when the slide rail drives the rotating wheel to move, the moving speed of the rotating wheel is also uniform, so the air pump ejects high-pressure gas with a certain periodicity, thereby making the cleaning of steel chips on the slide rail more continuous and stable, saving some resources for driving the air pump.

[0031] 2. In the worm processing technology and milling device described in the present invention, during the whirlwind milling process, the cutting fluid will continuously flush the whirlwind milling machine. During the process of the cutting fluid flushing the whirlwind milling machine, the cutting fluid will carry steel chips and fall into the collecting frame. After falling into the collecting frame, the liquid cutting fluid will pass through the filter screens arranged on both sides of the collecting frame, and then the cutting fluid flows through the filter screens, and the steel chips cannot pass through the filter screen, so that the cutting fluid flows into the fixed box along the guide groove and is collected by the fixed box to achieve the effect of recycling.

[0047] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0048] Embodiment 1

[0049] like Figures 1 to 10As shown, a worm gear milling device according to an embodiment of the present invention comprises a base 1, a fixed shell 2 is fixedly connected to the upper surface of the base 1, a fixed disk 21 is fixedly connected to one side of the fixed shell 2, a clamping assembly is arranged on the surface of the fixed disk 21, and the clamping assembly comprises three clamping blocks 22 slidably arranged on the side of the fixed disk 21, the three clamping blocks 22 are distributed in a circumferential array, and the bottom end of each clamping block 22 is in the shape of an arc of one-third of a circle; a slide rail 3 is fixedly connected to the middle part of the upper surface of the base 1, and a slider 31 is slidably connected to the surface of the slide rail 3; a first cavity 37 is opened in the middle part of the slider 31, and the first cavity 37 is rotatably arranged There is a rotating wheel 39, a rotating shaft 38 is fixedly connected to the middle of the rotating wheel 39, the rotating shaft 38 is rotatably connected to the inner wall of the first cavity 37, a fixed block 310 is fixedly connected to one side of the rotating wheel 39, and a switch 311 is rotatably provided on the slider 31 corresponding to the position of the fixed block 310; air pumps 313 are fixedly connected to both sides of the slider 31, and a same fixed pipe 314 is fixedly connected between the two air pumps 313; a support frame 32 is fixedly connected to the upper surface of the slider 31, and a motor is provided at the top of the support frame 32; a whirlwind milling machine 36 is rotatably provided in the middle of the support frame 32; and a control panel 4 is fixedly connected to one end of the upper surface of the base 1.

[0050] Specifically, when the milling device is used, since the whirlwind milling machine 36 is rotating at a high speed to cut the outer surface of the round steel, a thread with a certain inclination angle is generated on the outer surface of the round steel. However, during the cutting process of the whirlwind milling machine 36, due to the high cutting speed, some of the chips generated will be spattered, and some steel chips may be spattered on the guide rail. When the slider 31 slides, the steel chips are drawn between the slider 31 and the guide rail 3, thereby increasing the friction of the slider 31, and also causing the slider 31 to drive the steel chips to scratch the guide rail 3. After long-term use, the steel chips will cause greater wear on the slider 31 and the guide rail 3, thereby affecting the whirlwind milling machine 36 when cutting the round steel. When the slider 31 moves to the wear position of the guide rail 3, it will shake or shake, etc., which will cause errors in the cutting accuracy of the round steel, thereby reducing the production quality of the worm.

[0051] Therefore, the present invention is provided with an air pump 313 for cleaning the steel scraps on the slide rail 3. First, the round steel after round cutting is placed in the middle of the fixed plate 21 by the mechanical arm, and then one end of the round steel is fixed by the cooperation of the three fixed plates 21, and then the other end is fixed with the fixed plate 21. Figure 1The hydraulic cylinder in the middle control panel 4 is abutted, and after the round steel is fixed, the slider 31 is controlled to move through the control panel 4 to move the support frame 32 to the side close to the fixed disk 21, and then the motor is started to drive the whirlwind milling machine 36 in the middle of the support frame 32 to rotate, so as to cut the round steel. During the cutting process, the slider 31 is driven to move, so that the slider 31 moves with the support frame 32 and the whirlwind milling machine 36 in the direction away from the fixed disk 21. At the same time, the control panel 4 can control the moving speed of the slider 31 on the slide rail 3, so that the whirlwind milling machine 36 gradually cuts the entire round steel at a uniform speed. During the movement of the slider 31, the rotating wheel 39 opened in the first cavity 37 in the middle of the slider 31 will be driven to rotate at the same time. During the rotation of the rotating wheel 39, the fixed block 310 fixed to one side thereof will be driven to continuously twist the switch 311. No matter which direction the switch 311 is twisted, it will open the two sides of the start slider 31. The air pump 313 releases high-pressure gas in an instant, and the released high-pressure gas is ejected from the fixed pipe 314, and the air outlet 315 of the fixed pipe 314 is directed toward the slide rail 3 on one side of the fixed disk 21, thereby achieving the effect of cleaning the slide rail 3. During this process, the slider 31 moves at a uniform speed. Therefore, when the slider 31 drives the rotating wheel 39 to move, the moving speed of the rotating wheel 39 is also uniform. Therefore, the high-pressure gas ejected by the air pump 313 has a certain periodicity. If it is a continuous jet, when steel chips are hung on the slide rail 3, the continuous airflow cannot clean up the steel chips. However, the intermittent jet and the violent ejection of the airflow can produce a strong impact force on the static state, thereby blowing away the steel chips, making it more effective to clean the steel chips on the slide rail 3, and saving some resources for driving the air pump 313, thereby solving the problem that the steel chips will splash onto the slide rail 3 and damage the slider 31 and the slide rail 3.

[0052] like Fig. 9 As shown, in this embodiment, two torsion springs 312 are disposed at the position of the first cavity 37 corresponding to the switch 311 . The two torsion springs 312 are fixedly connected to both sides of the switch 311 . The torsion springs 312 drive the switch 311 to reset.

[0053] Specifically, in the process of rotating the rotating wheel 39 to drive the fixed block 310 to rotate and turn on the switch 311, in order to enable the switch 311 to intermittently control the air pump 313, thereby saving some resources for using the air pump 313, after the switch 311 is rotated, two torsion springs 312 are fixed on both sides thereof. When the fixed block 310 squeezes the switch 311 to power on the air pump 313, when the fixed block 310 is separated from the switch 311, the torsion spring 312 will drive the switch 311 to reset, thereby cutting off the power to the air pump 313, causing the air pump 313 to spray out high-pressure gas in an instant, thereby achieving a better cleaning effect on the slide rail 3.

[0054] like Figure 3As shown, the clamping assembly of this embodiment also includes three first hydraulic cylinders 23 embedded in one side of the fixed plate 21, the output end of each first hydraulic cylinder 23 is fixedly connected to a connecting plate 211, and each connecting plate 211 is fixedly connected to the top of the corresponding clamping block 22; a first groove body 24 is opened on one side of the bottom end of each clamping block 22, the inner wall of the first groove body 24 is fixedly connected to a first spring 25, and the end of the first spring 25 away from the clamping block 22 is fixedly connected to a magnetic block 26; a second groove body 212 is opened on the other side of the bottom end of the clamping block 22; a second spring 28 is fixed to the inside of the clamping block 22, one end of the second spring 28 is fixedly connected to a round rod 213, and the end of the round rod 213 away from the second spring 28 is fixedly connected to a limiting pad 29.

[0055] Specifically, when the clamping block 22 on the fixed plate 21 is used, when the round steel is placed in the middle of the fixed plate 21 by the mechanical arm, the three first liquid oxygen cylinders fixed to the fixed plate 21 are started, and each first hydraulic cylinder 23 drives the connecting plate 211 fixed to its output end, so that each connecting plate 211 moves toward the center round steel of the fixed plate 21, and the connecting plate 211 drives the clamping block 22 to move toward the round steel. When the limit pad 29 at the bottom end of the clamping block 22 abuts against the round steel, It is continuously retracted into the clamp block 22. When the limit pad 29 is engaged with the bottom end of the clamp block 22, the switch 311 in the clamp block 22 will be triggered, causing the electro-permanent magnet block 26 in the clamp block 22 to lose its magnetism. Then, the magnetic block 26 fixed in the first slot 24 by the first spring 25 will be released. The released magnetic block 26 will be inserted into the second slot 212 of another clamp block 22 and magnetically attracted to the other clamp block 22. The magnetic blocks 26 in the three magnetic blocks 26 cooperate with each other to clamp and fix the round steel.

[0056] like Figure 3 and Figure 4 As shown, in this embodiment, the second slot body 212 is one-third of the depth of the first slot body 24, the length of the magnetic block 26 is equal to the depth of the two second slot bodies 212, the compressed first spring 25 is the same depth as the second slot body 212, and the released first spring 25 is the same length as the magnetic block 26.

[0057] Specifically, when the magnet 26 is adsorbed and squeezed by the permanent magnet, the first spring 25 in this state has the same depth as the second slot 212. After the magnet 26 is released and inserted into the second slot 212 of another clamp 22, the first spring 25 is released to the same length as the magnet 26, and then the magnet 26 is inserted into the second slot 212. The second slot 212 is equivalent to half the length of the magnet 26. Therefore, the magnet 26 of each clamp 22 can fit perfectly with the second slot 212 of another clamp 22.

[0058] like Figure 3 and Figure 4As shown, in this embodiment, a limiting groove 210 is provided at the bottom end of the clamping block 22 corresponding to the position of the limiting pad 29, and the limiting pad 29 is embedded in the limiting groove 210. The bottom surfaces of the limiting pad 29 and the clamping block 22 are both provided with anti-slip grooves 27 for increasing the friction between the round steel.

[0059] Specifically, after the limit pad 29 abuts against the round steel, when the limit pad 29 and the round rod 213 are fully extended into the clamp block 22, the limit pad 29 will retract into the limit groove 210 opened at the bottom end of the clamp block 22. At the same time, anti-slip grooves 27 are opened at the bottom ends of the limit pad 29 and the clamp block 22 to ensure that the clamp block 22 can stably fix the round steel, so that the whirlwind milling machine 36 can achieve precise results when cutting the round steel.

[0060] like Figure 6 As shown, in this embodiment, a fixing ring 34 is fixedly connected to one side of the whirlwind milling machine 36 , and a plurality of grinding blocks 35 are fixedly connected to the inner wall of the fixing ring 34 . The plurality of grinding blocks 35 are distributed on the inner wall of the fixing ring 34 in a circular array.

[0061] Specifically, when the whirlwind milling machine 36 is rotating and cutting, a fixing ring 34 is fixedly connected to one side of the whirlwind milling machine 36, and then a plurality of threaded grinding blocks 35 are fixedly connected to the circumferential surface of the fixing ring 34. The grinding blocks 35 of the fixing ring 34 can simply grind the places where the whirlwind milling machine 36 has rotated and cut, so as to prevent the subsequent staff from accidentally injuring their hands when taking it for transportation.

[0062] like Figure 6 As shown, in this embodiment, two nozzles 33 are fixedly connected to the support frame 32 at the position corresponding to the whirlwind milling machine 36 for cutting. The nozzles 33 are used to spray cutting fluid to cool the whirlwind milling machine 36 to improve cutting accuracy and efficiency.

[0063] Specifically, in the process of the whirlwind milling machine 36 cutting, in order to make the milling cutter of the whirlwind milling machine 36 work for a long time, two nozzles 33 are fixedly connected at the position where the support frame 32 corresponds to the whirlwind milling machine 36 cutting, and the cutting fluid is sprayed through the nozzles 33 to cool the whirlwind milling machine 36, so as to improve the cutting accuracy and efficiency of the whirlwind milling machine 36.

[0064] Embodiment 2

[0065] like Figures 7 to 10 As shown, compared with Example 1, another embodiment of the present invention is: a collecting frame 316 is provided in the middle of the support frame 32, guide grooves 318 are provided on both sides of the support frame 32, a filter screen 317 is fixedly connected to the position of the collecting frame 316 corresponding to the guide groove 318, and a fixing box 319 is clamped to the position of the slider 31 corresponding to the guide groove 318.

[0066] Specifically, during the cutting process of the whirlwind milling machine 36, the cutting fluid will also continuously flush the whirlwind milling machine 36. In the process of the cutting fluid flushing the whirlwind milling machine 36, the cutting fluid will carry the steel chips and fall into the collection frame 316. After falling into the collection frame 316, the liquid cutting fluid will pass through the filter screen 317 set on both sides of the collection frame 316, and then the cutting fluid will flow through the filter screen 317, and the steel chips will not be able to pass through the filter screen 317, so that the cutting fluid will flow into the fixed box 319 along the guide groove 318, and be collected by the fixed box 319 to achieve the effect of recycling.

[0067] like Fig.10 As shown, two clamping blocks 320 are fixedly connected to both sides of the slider 31 of this embodiment, and a clamping groove 321 is provided at the position corresponding to the two clamping blocks 320 of the fixed box 319, and the clamping block 320 is clamped with the clamping groove 321, and two handles 322 are fixedly connected to both sides of the upper surface of the fixed box 319 for removing the fixed box 319.

[0068] Specifically, when using the fixed box 319, after the fixed box 319 is full of cutting fluid, the staff holds the handle 322 with both hands, then removes the fixed box 319 from the block 320, and then further filters the cutting fluid, thereby facilitating the collection of the cutting fluid. At the same time, the fixed box 319 can be replaced faster, thereby achieving the effect of timely collecting the cutting fluid.

[0069] A worm processing process, characterized in that it comprises the following specific steps:

[0070] Step 1: The raw material of the worm gear may be steel billet or other metal billet, which is manufactured into round steel with a circular cross-section through different processes, such as rolling or drawing. The long round steel strips are then cut into specific lengths using a round cutting machine, and the cut round steel is then transferred to a multi-purpose furnace to increase the hardness and strength of the material. The round steel is then processed using a milling device, and then the gear is ground using a gear grinding machine, which can further improve the accuracy and surface finish of the gear to meet the needs of high-precision applications.

[0071] Step 2: The specific process of gear milling is to first place the round steel after round cutting in the middle of the fixed plate through the mechanical arm, and then fix one end of the round steel through the cooperation of three fixed plates. After fixing the round steel, start the hydraulic cylinder in the control panel to hold the other end of the round steel away from the fixed plate, and then start the motor to drive the whirlwind milling machine to rotate. After the whirlwind milling machine rotates, it will cut the round steel at a certain angle, so that the round steel will be added into a worm. After the worm is processed, the worm is clamped by the mechanical arm, and the three first hydraulic cylinders on the fixed plate are closed to release the round steel. Then the mechanical arm will take the round steel out, place it on the transfer platform, and then enter the gear grinding device to grind the cutting position, so that the worm can be used more stably.

[0072] Step 3: The round steel after cutting has the function of a worm. In order to enhance its performance, the worm is placed in a nitriding furnace and exposed to a high temperature and nitrogen environment. This process will form a nitrided layer on the surface of the product, improve its hardness, wear resistance and corrosion resistance, and enhance the overall performance of the product. Finally, after quality inspection, the finished product is packaged and shipped to customers.

[0073] Working principle: when using the milling device, the whirlwind milling machine 36 rotates at high speed to cut the outer surface of the round steel, thereby generating a thread with a certain inclination angle on the outer surface of the round steel. However, during the cutting process of the whirlwind milling machine 36, due to the high cutting speed, some of the chips generated will be spattered, and some steel chips may be spattered on the guide rail. When the slider 31 slides, the steel chips are drawn between the slider 31 and the guide rail 3, thereby increasing the friction of the slider 31, and also causing the slider 31 to drive the steel chips to scratch the guide rail 3. After long-term use, the steel chips will cause greater wear on the slider 31 and the guide rail 3, thereby affecting the whirlwind milling machine 36 when cutting the round steel. When the slider 31 moves to the wear position of the guide rail 3, it will shake or shake, etc., which will cause errors in the cutting accuracy of the round steel, thereby reducing the production quality of the worm.

[0074] Therefore, the present invention is provided with an air pump 313 for cleaning steel scraps on the slide rail 3. First, the round steel after round cutting is placed in the middle of the fixed plate 21 by a mechanical arm. At this time, the three first liquid oxygen cylinders fixed to the fixed plate 21 are started. Each first hydraulic cylinder 23 drives the connecting plate 211 fixed to its output end, so that each connecting plate 211 moves toward the center round steel of the fixed plate 21. The connecting plate 211 drives the clamping block 22 to move toward the round steel. When the limit pad 29 at the bottom end of the clamping block 22 is aligned with the limit pad 29 at the bottom end of the clamping block 22, the clamping block 22 is moved to the center round steel. After the round steel is abutted, it will continuously retract into the clamp block 22. When the limit pad 29 is engaged with the bottom end of the clamp block 22, the switch 311 in the clamp block 22 will be triggered, causing the permanent magnet block 26 in the clamp block 22 to lose its magnetism. Then, the magnetic block 26 fixed in the first slot 24 by the first spring 25 will be released. The released magnetic block 26 will be inserted into the second slot 212 of another clamp block 22 and magnetically attracted to the other clamp block 22. The magnetic blocks 26 in the three magnetic blocks 26 cooperate with each other, thereby clamping and fixing the round steel.

[0075] Then the other end is connected with Figure 1The hydraulic cylinder in the control panel 4 is in contact with the round steel, and after the round steel is fixed, the control panel 4 controls the movement of the slider 31 to move the support frame 32 to the side close to the fixed plate 21, and then the motor is started to drive the whirlwind milling machine 36 in the middle of the support frame 32 to rotate, so as to cut the round steel. During the cutting process, the control panel 4 starts the slider 31 again, so that the slider 31 moves with the support frame 32 and the whirlwind milling machine 36 in the direction away from the fixed plate 21. At the same time, the control panel 4 can control the moving speed of the slider 31 on the slide rail 3, so that the whirlwind milling machine 36 gradually cuts the entire round steel at a uniform speed. During the movement of the slider 31, the rotating wheel 39 opened in the first cavity 37 in the middle of the slider 31 will be driven to rotate at the same time. During the rotation of the rotating wheel 39, the fixed block 310 fixed to one side thereof will be driven to continuously twist the switch 311. After the switch 311 is rotated, two torsion springs 312 are fixed on both sides thereof. When the fixed block 310 squeezes the switch 311 to energize the air pump 313, when the fixed block 310 is separated from the switch 311, the torsion spring 312 will drive the switch 311 to reset, thereby cutting off the power to the air pump 313. No matter which direction the switch 311 is twisted, the air pump 313 on both sides of the starting slider 31 will be turned on, causing the air pump 313 to release high-pressure gas in an instant. The released high-pressure gas is ejected from the fixed pipe 314, and the fixed pipe 314 is directed toward one side of the slide rail 3, thereby achieving the effect of cleaning the slide rail 3. During this process, the slide rail 31 moves at a uniform speed. Therefore, when the slide rail 31 drives the rotating wheel 39 to move, the moving speed of the rotating wheel 39 is also uniform. Therefore, the air pump 313 ejects high-pressure gas with a certain periodicity, thereby making the cleaning of steel chips on the slide rail 3 more continuous and stable, saving some resources for driving the air pump 313, and thus solving the problem that steel chips will splash onto the slide rail 3 and cause damage to the slide rail 31 and the slide rail 3.

[0076] At the same time, during the cutting process of the whirlwind milling machine 36, the cutting fluid will also continuously flush the whirlwind milling machine 36. During the process of the cutting fluid flushing the whirlwind milling machine 36, the cutting fluid carries the steel chips and falls into the collecting frame 316. After falling into the collecting frame 316, the liquid cutting fluid will pass through the filter screen 317 set on both sides of the collecting frame 316, and then the cutting fluid flows through the filter screen 317, and the steel chips cannot pass through the filter screen 317, so that the cutting fluid flows into the fixed box 319 along the guide groove 318, and is collected by the fixed box 319 to achieve the effect of recycling.
