Description

Technical Field

[0001] This invention relates to a processing technology for automotive worm gears, and more particularly to a processing technology for automotive worm gears applied in the field of worm gear processing. Background Technology

[0002] A worm gear is a specially designed gear. Because multiple parts of the worm typically mesh simultaneously with the worm wheel, this type of worm drive has a very high load capacity, meaning it can transmit very high power. It has important applications in automotive and machining. In the machining of automotive worm gears, grinding and polishing are usually required. To handle the debris generated during grinding and polishing, suction or brush cleaning methods are commonly used. However, the limited space inside a lathe makes debris removal difficult.

[0003] To address the difficulty of cleaning up waste chips, a certain worm gear processing device on the market adopts a design that allows for flexible disassembly of brushes, and it has a certain market share.

[0004] Chinese invention patent CN110449667B discloses a worm gear machining device for easy cleaning of waste chips, including a lathe body with mounting blocks fixedly connected to both sides. This worm gear machining device uses a toothed rack to cause the lathe body to rotate, which in turn drives a rotating gear as the movable plate, connecting rod, and movable blocks move. The rotating gear causes a rotating shaft to rotate, which in turn drives the mounting plate and brush to rotate, thus cleaning the interior of the lathe. When the waste chips are swept into the collection trough by the brush, they are discharged from the outside of the lathe body through the discharge port. This device, through a series of mechanical structures, transforms the lathe body, which previously required manual cleaning, into an automatic cleaning process, making cleaning faster and more convenient while reducing the safety hazards associated with manual cleaning. The device also fully utilizes the force of the moving plate, making it more environmentally friendly.

[0005] The aforementioned device achieves automated brush cleaning by arranging the brushes in a stepped manner and allowing for flexible disassembly. However, during the grinding process, debris falling from the worm gear surface will splash onto the inner wall of the lathe and bounce back onto the grinding head or the worm gear surface, thus affecting the grinding accuracy. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to reduce the interference of grinding debris during the grinding process.

[0007] To address the aforementioned problems, this invention provides a machining process for automotive worm gears, comprising a grinding lathe, a slide rail mounted on the rear wall of the grinding lathe, a grinding head slidably connected to the surface of the slide rail, a support shaft mounted in the middle of the bottom wall of the grinding lathe, a receiving plate mounted on the surface of the support shaft, a fixed clamping plate mounted on one side of the top of the receiving plate, a movable clamping plate arranged above the receiving plate, and arrayed clamping wall units mounted on both inner walls of the grinding lathe, each clamping wall unit including an impact plate. Rotating round rods are movably connected to both inner walls of the grinding lathe via mounting brackets, and the rotating round rods are fixedly connected to the surface of the impact plates. An arc-shaped cover is connected to the surface of the rotating round rods.

[0008] The specific processing technology includes the following steps:

[0009] S1. The worm gear to be processed is constrained using a movable clamping plate;

[0010] S2. Start the grinding head to grind the clamped worm gear;

[0011] S3. During the grinding process, the clamping wall unit is used to decelerate and redirect the splashed fragments;

[0012] S4. Adjust one side of the receiving plate to collect and transfer the debris on the surface of the receiving plate into the waste bin.

[0013] In the above-mentioned automotive worm gear processing technology, the clamping unit and dust-binding unit can effectively decelerate and redirect fragments and chips of different sizes during the grinding process, avoid chip splashing accidents during grinding, and indirectly improve grinding accuracy.

[0014] As a further improvement of this application, there is a horizontal gap between the end of the receiving plate near the rear wall of the grinding lathe and the rear wall of the grinding lathe, and a waste bin with an open top is installed at the bottom of the grinding lathe.

[0015] As a further improvement of this application, the horizontal axis of the bottom of the arc-shaped cover is located above the horizontal axis of the top of the impact plate, there is a gap between the surface of the impact plate and the inner wall of the grinding lathe, and the horizontal span of the arc-shaped cover is greater than the height of the impact plate.

[0016] As a further improvement of this application, a servo motor is installed at the rear of one side surface of the grinding lathe. The output end of the servo motor is connected to a lead screw located inside the grinding lathe. A threaded sleeve is connected to the surface of the lead screw, and the surface of the threaded sleeve is connected to the bottom surface of the movable clamping plate.

[0017] As a further improvement to this application, the fixed clamping plate has a through hole inside and the lead screw passes through the inside of the through hole, and the diameter of the through hole is larger than the diameter of the lead screw.

[0018] To further improve this application, the surface of the impact plate is equipped with an array of dust-binding units. Each dust-binding unit includes a crossbar, a movable shaft is sleeved on the surface of the crossbar, movable clamps are symmetrically hinged on the surface of the movable shaft, and a bracket is mounted on the surface of the crossbar symmetrically about the movable shaft. A flipping support plate is mounted on the tail end of the bracket via a bearing.

[0019] As another improvement of this application, the height of the flip support plate is less than the diameter of the movable clamping plate, and an electromagnetic block is installed inside the two movable clamping plates on each movable shaft surface, and the two electromagnetic blocks have a repulsive effect. A spring strip is installed on the surface of the impact plate, and the tail end of the spring strip is pressed and connected to the surface of the lower movable clamping plate in the initial state. The side surface of the flip support plate near the bracket is coated with a magnetic coating that repels the lower electromagnetic block, and the length of the flip support plate is less than the diameter of the movable clamping plate.

[0020] As another improvement of this application, the movable clamp includes a base plate, a rocking spring is mounted on the surface of the base plate, a sponge plate is connected to the tail end of the rocking spring, and an electromagnetic block is installed inside the sponge plate.

[0021] In summary, this application, through the cooperation of the clamping unit and the dust-binding unit, can effectively decelerate and redirect fragments and chips of different sizes during the grinding process. During the grinding process, the impact of the chips and fragments allows the arc-shaped cover and the movable clamping plate to switch positions to prevent the splashed chips and fragments from rebounding along their original path, thus avoiding chip splashing accidents during the grinding process and indirectly improving the grinding accuracy.

[0034] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0035] Implementation method 1:

[0036] Figures 1-9 This invention illustrates a machining process for automotive worm gears, comprising a grinding lathe 1, a slide rail 11 mounted on the rear wall of the grinding lathe 1, a grinding head 12 slidably connected to the surface of the slide rail 11, a support shaft mounted in the middle of the bottom wall of the grinding lathe 1, a receiving plate 2 mounted on the surface of the support shaft, a fixed clamping plate 3 mounted on one side of the top of the receiving plate 2, a movable clamping plate 4 arranged above the receiving plate 2, and arrayed clamping wall units 5 mounted on both inner walls of the grinding lathe 1, each clamping wall unit 5 including an impact plate 51. Rotating round rods are movably connected to both inner walls of the grinding lathe 1 via mounting brackets, and the rotating round rods are fixedly connected to the surface of the impact plate 51. An arc-shaped cover 52 is connected to the surface of the rotating round rods.

[0037] The specific processing technology includes the following steps:

[0038] S1. The worm gear to be processed is constrained by the movable clamping plate 4.

[0039] S2. Start the grinding head 12 to grind the clamped worm gear;

[0040] S3. During the grinding process, the clamping wall unit 5 is used to decelerate and redirect the splashed fragments;

[0041] S4. Adjust one side of the receiving plate 2 to transfer the debris on the surface of the receiving plate 2 to the waste bin 6.

[0042] There is a horizontal gap between the end of the receiving plate 2 near the rear wall of the grinding lathe 1 and the rear wall of the grinding lathe 1. The bottom of the grinding lathe 1 is equipped with a waste bin 6 located below the grinding head 12 and with an open top.

[0043] The horizontal axis of the bottom of the arc-shaped cover 52 is located above the horizontal axis of the top of the impact plate 51. There is a gap between the surface of the impact plate 51 and the inner wall of the grinding lathe 1. The horizontal span of the arc-shaped cover 52 is greater than the height of the impact plate 51.

[0044] A servo motor 7 is installed at the rear of one side surface of the grinding lathe 1. The output end of the servo motor 7 is connected to a lead screw 71 located inside the grinding lathe 1. A threaded sleeve is connected to the surface of the lead screw 71, and the surface of the threaded sleeve is connected to the bottom surface of the movable clamping plate 4.

[0045] The fixed clamping plate 3 has a through hole 31 inside and the lead screw 71 passes through the inside of the through hole 31. The diameter of the through hole 31 is larger than the diameter of the lead screw 71.

[0046] The surface of the impact plate 51 is equipped with an array of dust-binding units 8. Each dust-binding unit 8 includes a crossbar. A movable shaft 84 is sleeved on the surface of the crossbar. Movable clamping plates 81 are symmetrically hinged to the surface of the movable shaft 84. A bracket 83 is symmetrically arranged about the movable shaft 84 on the surface of the crossbar. A flipping support plate 82 is mounted on the tail end of the bracket 83 via a bearing.

[0047] The height of the flip support plate 82 is less than the diameter of the movable clamping plate 81, and an electromagnetic block 85 is installed inside the two movable clamping plates 81 on the surface of each movable shaft 84. The two electromagnetic blocks 85 have a repulsive effect. A spring strip is installed on the surface of the impact plate 51, and the tail end of the spring strip is pressed and connected to the surface of the lower movable clamping plate 81 in the initial state. The side of the flip support plate 82 near the bracket 83 is coated with a magnetic coating that repels the lower electromagnetic block 85. The length of the flip support plate 82 is less than the diameter of the movable clamping plate 81.

[0048] Specifically, when grinding the automotive worm gear, the worm gear to be processed is placed into the grinding lathe 1 with a window on the front. Then, one end of the worm gear is pressed against the surface of the fixed clamping plate 3. The servo motor 7 is started, and the position of the movable clamping plate 4 is adjusted by rotating the lead screw 71 until the surface of the movable clamping plate 4 is pressed into contact with the other end of the worm gear. At this time, the servo motor 7 is stopped.

[0049] Then close the window on the front of the grinding lathe 1 to make the grinding lathe 1 form a relatively closed structure, and use the grinding head 12 to grind the surface of the worm.

[0050] During the grinding process, larger-diameter fragments are splashed onto the surface of the impact plate 51. The impact causes the impact plate 51 to move closer to the inner wall of the grinding lathe 1. At this time, the arc-shaped cover 52 rotates synchronously, which shields the rebound of the fragments after impact. This causes the fragments to rebound and hit the surface of the arc-shaped cover 52, and be forced to change their direction of movement to a downward direction, so that the fragments fall on the surface of the receiving plate 2 without rebounding.

[0051] In addition, small-sized debris generated during the grinding process splashes onto the surface of the impact plate 51. However, due to its small weight and small impact, it will not cause the impact plate 51 to rotate significantly. At this time, the dust-binding unit 8 can be used for constraint treatment. When the small-sized debris enters the inner side of the two movable clamping plates 81, it will have an impact effect on the flipping support plate 82, thereby causing the flipping support plate 82 to rotate at a certain angle. Then the movable clamping plate 81 loses the constraint and limiting effect of the flipping support plate 82 and moves inward to cover the debris that enters, preventing the debris from escaping and rebounding.

[0052] After polishing, the electromagnetic block 85 is activated, which increases the angle between the two electromagnetic blocks 85, making it easier for the debris covered between the two movable clamping plates 81 to detach and fall onto the surface of the receiving plate 2. At the same time, the flip support plate 82 is switched from its original horizontal state to a vertical state (in the horizontal state, the magnetic coating at the bottom of the flip support plate 82 and the electromagnetic block 85 below have a magnetic repulsion effect). Then the electromagnetic block 85 is turned off, and the lower movable clamping plate 81 is reset under the action of the spring bar, and the upper movable clamping plate 81 overlaps the surface of the flip support plate 82.

[0053] Therefore, through the cooperation of the clamping wall unit 5 and the dust-binding unit 8, the fragments and chips of different particle sizes can be effectively decelerated and redirected during the grinding process, avoiding the occurrence of chip splashing accidents during the grinding process and indirectly improving the grinding accuracy.

[0054] When the debris on the surface of the receiving plate 2 needs to be collected and processed after grinding, the end of the receiving plate 2 away from the waste bin 6 is lifted to form a slope, so that the debris on the surface of the receiving plate 2 slides into the waste bin 6 by gravity. During this process, since the diameter of the through hole 31 is larger than the diameter of the lead screw 71, even if the receiving plate 2 is tilted, there is enough space to ensure that the fixing clamping plate 3 will not interfere with the lead screw 71.

[0055] The second implementation method:

[0056] Figure 10 The movable clamp 81 shown includes a base plate 811, a rocking spring 813 is mounted on the surface of the base plate 811, the tail end of the rocking spring 813 is connected to a sponge plate 812, and an electromagnetic block 85 is installed inside the sponge plate 812.

[0057] Specifically, when releasing the debris in the movable clamping plate 81, since the movable clamping plate 81 changes from a covered state to an open state, the previously compressed rocking spring 813 is released and restored, causing the sponge plate 812 to shake, so as to shake off the dust in the sponge plate 812 and the debris trapped in the small holes on the surface of the sponge plate 812, thereby enhancing the chip removal effect.

[0058] The use of sponge board 812 makes the debris retention effect more stable.

[0059] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
