Description

Technical Field

[0001] This invention relates to the field of gear processing technology, specifically a planar gear processing device. Background Technology

[0002] In the field of planar gear machining, cylindrical gears, as a type of planar gear, have attracted much attention in terms of their machining methods. Currently, common cylindrical gear machining methods include turning and casting. After machining, cylindrical gears usually need to be ground to ensure quality. Grinding can improve the surface quality of the gear, reduce tooth surface roughness, improve transmission accuracy, and reduce noise and wear during operation.

[0003] Current grinding methods primarily involve clamping and fixing the gear, then bringing the grinding wheel close to the tooth gap and moving it back and forth along the gear's axis while the grinding wheel rotates. The gear rotates with the clamped workpiece, thus grinding all the teeth. However, this method has significant drawbacks: the clamping process is cumbersome, time-consuming, and may introduce clamping errors, affecting grinding accuracy; furthermore, the overall process of grinding after clamping is inefficient, as clamping and unclamping the gear adds extra steps and reduces production efficiency; additionally, the motion control of the grinding wheel during grinding is relatively complex, requiring precise movement along the tooth gap and ensuring uniform grinding, which places high demands on equipment and operation. Even slight errors can lead to uneven grinding, affecting gear quality. These problems urgently require more efficient and precise processing methods to solve. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a planar gear processing device. This invention uses a limiting strip to axially limit the gear to be processed and controls the grinding plate meshing with the gear to move back and forth along the axial direction of the gear, so that the gear can achieve tooth grinding by rolling under its own gravity. This eliminates the traditional clamping and fixing method, saves processing time, and improves production efficiency. In addition, this invention also has the characteristics of continuous production and higher precision.

[0006] Preferably, the lower surface of the grinding machine is provided with threaded holes near the four corners; the threaded holes are internally threaded to threaded feet; the threaded feet pass through the rotating handle radially; the threaded feet at the rear end extend beyond the corresponding threaded holes by a greater length than the threaded feet at the front end extend beyond the corresponding threaded holes.

[0007] Preferably, the length of the threaded support leg extending out of the corresponding threaded hole on the left side is different from the length of the threaded support leg extending out of the corresponding threaded hole on the right side.

[0008] Preferably, the grinding machine has two base strips located on the top of it, near the left and right sides; the two base strips are located on both sides of the two limiting strips; the two limiting strips are rotatably connected to a screw and a slide bar on opposite sides; the end of the slide bar away from the limiting strip passes through the base strip and is slidably connected to the base strip; the end of the screw bar away from the limiting strip passes through the base strip and is threadedly connected to the base strip.

[0009] Preferably, the lower surface of the base strip is connected to the upper surface of the grinding machine via an electric push rod; the two electric push rods are positioned near the lateral edge of the grinding machine.

[0010] Preferably, the upper surface of the limiting strip is rotatably connected to a rotating wheel near the front and rear ends; the outer walls of the two corresponding rotating wheels are connected to a transmission belt; and the outer wall of the transmission belt is uniformly provided with partitions along the transmission direction.

[0011] Preferably, the partition is composed of an inner partition bar and an outer partition sleeve; the partition bar is connected to the transmission belt; the partition sleeve is rotatably connected to the partition bar; the outer layer of the partition sleeve is elastic and the inner layer is rigid.

[0012] Preferably, the outer wall of the transmission belt is provided with a plurality of insertion holes evenly distributed along the transmission direction; the partition bar can be inserted into the corresponding insertion hole; a locking hole is provided through the insertion hole facing upward; a locking pin is movably connected in the locking hole; the outer wall of the partition bar is provided with a partition hole corresponding to the locking hole; the locking pin can be inserted into the partition hole.

[0013] Preferably, the upper gear plate is spliced ​​to the rear end of the grinding plate in the same horizontal state; the upper gear plate and the grinding plate are in sliding contact; the upper gear plate and the grinding plate are in seamless contact; the upper gear plate is fixedly connected to the grinding machine by a diagonal bar.

[0014] Preferably, the limiting strip extends rearward and is provided with a guide strip; the two guide strips are arranged in a figure-eight shape; the guide strips extend to directly above the upper toothed plate.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention uses a limiting strip to axially limit the gear to be processed and controls the grinding plate that meshes with the gear to be processed to move back and forth along the axial direction of the gear to be processed. This allows the gear to roll under its own weight to achieve the grinding of the teeth on the gear, eliminating the traditional clamping and fixing method, saving processing time and improving production efficiency. In addition, this invention also has the characteristics of continuous production and higher precision.

[0017] 2. This invention rotates the threaded support by turning the rotating handle, keeping the rear end of the grinding machine higher than the front end, thereby changing the tilt of the grinding machine and the grinding plate to meet different gear processing requirements; and the length of the threaded support extending from the corresponding threaded hole on the left side of the bottom of the grinding machine is different from the length of the threaded support extending from the corresponding threaded hole on the right side, so that the grinding machine will tilt slightly to the left or right. In this way, during the grinding process of the grinding plate on the gear, the grinding debris can flow along the upper surface of the grinding plate and towards a lower position.

[0018] 3. Before processing the teeth of the gear using processing equipment, the present invention first screws the screw rod. The screw rod is threadedly connected to the base strip. Therefore, during the screwing process, the screw rod can drive the limiting strip away from or towards the base strip. During the process of the limiting strip moving away from or towards the corresponding base strip, it will drive the sliding bar to slide with the corresponding base strip. This makes the distance between the two limiting strips adjustable, which can meet the processing needs of gears of different thicknesses and has a wider range of applications.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 10 As shown, the present invention includes the following embodiments:

[0033] Example 1: A planar gear processing device includes a grinding machine 1 and a grinding plate 2 on the upper surface of the grinding machine 1; the grinding plate 2 is plate-shaped with the teeth facing upwards; a slide rod 12 is fixedly connected to the front and rear positions of the upper surface of the grinding machine 1 by a support block 11; the length direction of the slide rod 12 is consistent with the width direction of the grinding machine 1; the grinding plate 2 is slidably connected to the slide rod 12 through a sliding hole 21; a driving gap 22 is left between the grinding plate 2 and the grinding machine 1; a strip-shaped driving groove 23 is provided on the lower surface of the grinding plate 2 along the front and rear direction; A drive rod 24 is movably connected within the drive groove 23; the lower end of the drive rod 24 is eccentrically fixed to a drive disk 25; the center of the lower surface of the drive disk 25 is fixedly connected to the upper surface of the grinding machine 1 via a drive motor 26; the front end of the grinding plate 2 is fixedly connected to a discharge plate 27; the front end of the grinding machine 1 is lower than the rear end in vertical height; two limiting strips 3 are provided directly above the grinding plate 2; the length direction of the two limiting strips 3 is consistent with the front-rear direction; a limiting gap 31 is formed between the two limiting strips 3.

[0034] The end of the grinding plate 2 connected to the unloading plate 27 is the front end, and the end away from the unloading plate 27 is the rear end. After the gear to be processed moves to the rear end position of the processing equipment, the drive motor 26 is controlled to rotate. During the rotation of the drive motor 26, the drive disk 25 will rotate. During the rotation of the drive disk 25, the drive rod 24 will move along the drive groove 23. The grinding plate 2 is slidably connected to the slide rod 12 through the sliding hole 21. Therefore, during the rotation of the drive disk 25 and the eccentric drive rod 24, the grinding plate 2 will move back and forth along the slide rod 12 in the left and right directions. After the gear to be processed is placed at the rear position on the upper surface of the grinding plate 2, the gear to be processed will enter the limiting gap 31. Since the grinding plate 2 is parallel to the grinding machine 1, when the front end of the grinding machine 1 is lower than the rear end, the front end of the grinding plate 2 will be lower than the rear end. Thus, under the action of the gear's own gravity, the gear to be processed will mesh and roll along the grinding plate 2. The hardness of the grinding plate 2 is greater than that of the gear to be processed. The grinding plate 2 is equivalent to a grinding knife and can grind the teeth of the gear to be processed. The gear to be processed will not tip over under the limit of the two limit bars 3 on the left and right sides, so it will roll forward along the upper surface of the grinding plate 2 in a rolling state. The gear to be processed will roll at least one revolution on the grinding plate 2, so that the teeth of the gear to be processed will be ground. Since the teeth of the gear to be processed are ground in a meshing state, the grinding precision is higher and the grinding quality is better. The ground gear will eventually be discharged from the front end of the upper surface of the grinding plate 2 and enter the unloading plate 27, and finally flow into the elastic collection frame (not shown in the figure) with buffer protection. The gears to be processed are continuously placed at the rear end of the upper surface of the grinding plate 2. Multiple gears to be processed roll forward along the upper surface of the grinding plate 2 under their own weight and enter the limit gap 31. Multiple gears to be processed continuously roll forward along the upper surface of the grinding plate 2 to achieve grinding, and so on.

[0035] This invention uses a limiting strip 3 to axially limit the gear to be processed and controls the grinding plate 2 that meshes with the gear to be processed to move back and forth along the axial direction of the gear to be processed. This allows the gear to roll by its own gravity to achieve the grinding of the teeth on the gear, eliminating the traditional clamping and fixing method, saving processing time and improving production efficiency. In addition, this invention also has the characteristics of continuous production and higher precision.

[0036] Example 2: The lower surface of the grinding machine 1 is provided with threaded holes (not shown in the figure) near the four corners; the threaded holes are connected to threaded legs 14 by internal threads; the threaded legs 14 pass through the rotating handle 15 radially; the threaded legs 14 at the rear position extend beyond the corresponding threaded holes by a greater length than the threaded legs 14 at the front position extend beyond the corresponding threaded holes.

[0037] The length by which the threaded support leg 14 on the left extends out of the corresponding threaded hole is different from the length by which the threaded support leg 14 on the right extends out of the corresponding threaded hole.

[0038] The rolling time of the gear to be processed on the upper surface of the grinding plate 2 directly affects the processing time of the gear. When the drive motor 26 rotates at the same speed, the longer the rolling time of the gear to be processed on the grinding plate 2, the greater the degree of processing of the gear to be processed, and vice versa. Therefore, before processing the gear, the two threaded feet 14 at the rear end of the grinding machine 1 are adjusted. Specifically, the rotating handle 15 is turned to drive the threaded feet 14 to rotate. While keeping the rear end of the grinding machine 1 higher than the front end, the tilt of the grinding machine 1 and the grinding plate 2 is changed to meet different gear processing requirements.

[0039] In addition, the length of the threaded support leg 14 extending from the corresponding threaded hole on the left side of the bottom of the grinding machine 1 is different from that on the right side. This causes the grinding machine 1 to tilt slightly to the left or right. As a result, during the grinding process of the gear grinding plate 2, the grinding debris can flow along the upper surface of the grinding plate 2 and towards a lower position. For example, if the left side of the grinding plate 2 is lower than the right side, the debris on the grinding plate 2 will flow down along the left side, preventing the grinding debris from remaining on the grinding plate and affecting the processing effect of other gears. In addition, the grinding plate itself moves back and forth from left to right, so the debris on the grinding plate can also be smoothly unloaded under the action of inertia or vibration. During the grinding process of the gear to be processed by the grinding plate 2, cutting fluid can also be sprayed in. The cutting fluid will flow from the right side to the left side to achieve the purpose of cooling and cleaning debris.

[0040] Example 3: Two base bars 4 are provided on the top of the grinding machine 1 near the left and right sides; the two base bars 4 are located on both sides of the two limiting bars 3; the two limiting bars 3 are rotatably connected to a screw 41 and a slide bar 42 on opposite sides; the end of the slide bar 42 away from the limiting bar 3 passes through the base bar 4 and is slidably connected to the base bar 4; the end of the screw 41 away from the limiting bar 3 passes through the base bar 4 and is threadedly connected to the base bar 4.

[0041] The lower surface of the base strip 4 is connected to the upper surface of the grinding machine 1 by an electric push rod 43; the two electric push rods 43 are arranged near the lateral edge of the grinding machine 1.

[0042] Before machining the gear teeth using the processing equipment, screw 41 is first tightened. Screw 41 is threadedly connected to base 4, so during the tightening process, screw 41 can move the limiting strip 3 away from or closer to base 4. During the process of the limiting strip 3 moving away from or closer to the corresponding base 4, it will cause the sliding bar 42 to slide with the corresponding base 4. This makes the distance between the two limiting strips 3 adjustable, meeting the processing needs of gears of different thicknesses and expanding the application range. Furthermore, the lower surface of base 4 is connected to the upper surface of grinding machine 1 by electric push rod 43. During the extension and retraction of electric push rod 43, base 4 will move up or down. The vertical height of limiting strip 3 will change with the position of base 4, so that limiting strip 3 can limit the gear at different height positions, thereby meeting the limiting requirements of gears of different diameters and expanding the application range of the processing equipment. Note that the grinding adaptability requirements of the gear to be processed must be able to mesh with the grinding plate 2.

[0043] Example 4: The upper surface of the limiting strip 3 is rotatably connected to the wheel 5 near the front and rear ends; the outer walls of the two corresponding wheels 5 are connected to the transmission belt 51; the outer wall of the transmission belt 51 is uniformly provided with partitions 6 along the transmission direction.

[0044] The partition 6 is composed of an inner partition rod 61 and an outer partition sleeve 62; the partition rod 61 is connected to the transmission belt 51; the partition sleeve 62 is rotatably connected to the partition rod 61; the outer layer of the partition sleeve 62 is elastic and the inner layer is rigid.

[0045] After the gear to be processed enters the limiting gap 31 formed between the two limiting bars 3, the gear to be processed will be restricted by the limiting bars 3 and the transmission belt 51 to prevent it from tilting to the left or right. The gear will enter between two adjacent spacers 6 on the transmission belt 51. The gear will roll forward under the spacer. The size of the spacer 6 is larger than the tooth gap of the gear to be processed, so that the spacer 6 will not get stuck in the tooth gap of the gear and prevent the gear from rotating. Since the processing equipment can grind multiple gears at the same time, in order to avoid adjacent gears contacting each other and causing tooth jamming or damage, two adjacent gears are separated by the spacer 6 to achieve multi-gear grinding. In addition to the protection during the gear processing, as some gears roll forward, the gears will push the corresponding spacer 6 forward. The spacer 6 is connected to the transmission belt 51, so it can drive the entire transmission belt 51 to rotate along the corresponding two pulleys 5. In this way, all the spacers 6 on the transmission belt 51 can be driven, so that other gears that have stopped rolling can still roll forward. This makes the gear processing more continuous and avoids situations such as stoppage. Stopped gears will cause over-grinding and uneven gear grinding. This continuous rolling of the gears ensures the uniformity of the teeth after processing and improves the gear processing quality.

[0046] Furthermore, the partition 6 is composed of an inner partition rod 61 and an outer partition sleeve 62 rotatably connected. During the forward rolling of the gear, it will contact the partition sleeve 62 in the corresponding partition 6. The partition sleeve 62 is rotatably connected to the outer wall of the partition rod 61, so that the contact between the partition 6 and the gear is a rolling contact, reducing the wear of the partition 6 on the gear during the partitioning process. In addition, the outer layer of the partition sleeve 62 is elastic, realizing the contact buffer between the gear and the partition 6. When two adjacent gears are in rolling contact with the partition 6, the partition sleeve 62 in the partition 6 acts as an intermediate "transition gear" so that the rolling of the two adjacent gears can be transmitted, thereby enabling multiple gears to roll forward and grind stably and smoothly, improving the stability of the gear grinding of the processing equipment.

[0047] Example 5: The outer wall of the transmission belt 51 is provided with a plurality of insertion holes 52 evenly arranged along the transmission direction; the partition rod 61 can be inserted into the corresponding insertion hole 52; the insertion hole 52 is provided with a locking hole 53 through it facing upward; a locking pin 54 is movably connected in the locking hole 53; the outer wall of the partition rod 61 is provided with a partition hole 63 corresponding to the locking hole 53; the locking pin 54 can be inserted into the partition hole 63.

[0048] Before gear machining, adjust the number of corresponding spacers 6 on the transmission belt 51 according to the gear diameter. The more spacers 6 on the transmission belt 51, the more suitable they are for machining gears with smaller diameters. The fewer spacers 6 on the transmission belt 51, the more suitable they are for machining gears with larger diameters. To reduce the number of spacers 6, first pull the locking pin 54 out of the locking hole 53. As the locking pin 54 moves upward, pull it out of the spacer hole 63. Then, pull the spacer bar 61 in the spacer 6 out of the insertion hole 52. To increase the number of spacers 6, insert the spacer bar 61 into the insertion hole 52 and align the spacer hole 63 on the spacer bar 61 with the locking hole 53. Then, insert the locking pin 54 along the locking hole 53 into the spacer hole 63 to lock the spacer bar 61 in the insertion hole 52, thus completing the installation of the spacer 6.

[0049] Example 6: The upper gear plate 7 is spliced ​​to the rear end of the grinding plate 2 in the same horizontal state; the upper gear plate 7 and the grinding plate 2 are in sliding contact; the upper gear plate 7 and the grinding plate 2 are in seamless contact; the upper gear plate 7 is fixedly connected to the grinding machine 1 by a diagonal rod 71.

[0050] The limiting strip 3 extends rearward and is provided with a guide strip 32; the two guide strips 32 are arranged in a figure-eight shape; the guide strips 32 extend to the top of the upper toothed plate 7.

[0051] After the operator places the gear to be processed onto the upper gear plate 7, the upper gear plate 7 meshes with the gear. The inclination of the upper gear plate 7 is consistent with that of the grinding plate 2, but the upper gear plate 7 remains stationary while the grinding plate 2 remains in a sliding state. As the upper gear plate 7 rolls forward, it will smoothly transition onto the grinding plate 2, avoiding direct placement that could cause tooth collision and thus protecting the upper teeth of the gear. As the gear rolls forward, two figure-eight shaped guide strips 32 guide the gear, allowing it to roll smoothly into the limiting gap 31.
