Description

Technical Field

[0001] This utility model relates to the field of gear grinding technology, specifically a gear inner ring processing device. Background Technology

[0002] Gears are mechanical components with continuously meshing gears on their rims that transmit motion and power. Gears are widely used in mechanical transmission. During machining, in order to make the inner wall of the gear hole meet the roughness requirements or the assembly hole diameter requirements, a grinding machine is needed for fine-tuning and grinding.

[0003] Publication No. CN219274706U discloses a gear deburring and polishing device. This device places and clamps the gear in a fixture, turns on the motor, and then controls the mounting bar to descend via a lifting mechanism. This allows a polishing ring to polish the circumference of the gear, a polishing column to polish the sidewalls of the gear mounting hole, and a polishing disc to polish the upper surface of the gear. This makes gear polishing relatively convenient. Furthermore, the gear can be inverted and clamped for further polishing to ensure more thorough polishing and improve the quality of the polishing. However, this patent still has the following problems in practical use:

[0004] This device places and clamps the gear in a fixture, and controls the mounting bar to descend via a lifting component. This allows the grinding ring to grind the circumference of the gear, the grinding column to grind the sidewalls of the gear mounting hole, and the grinding disc to grind the upper surface of the gear. However, this device can only grind the inner ring of a single gear and cannot achieve the effect of synchronously grinding the inner rings of multiple gears, thus greatly reducing the efficiency of gear production and processing.

[0005] A gear inner ring machining apparatus is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a gear inner ring processing device to solve the problem mentioned in the background art. The current method involves placing the gear in a fixture and clamping it, controlling the installation bar to descend via a lifting component, so that the grinding ring can grind the circumference of the gear, the grinding column can grind the side wall of the gear mounting hole, and the grinding disc can grind the upper end face of the gear. However, this device can only grind the inner ring of a single gear and cannot achieve the effect of synchronous grinding of multiple gear inner rings.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a gear inner ring processing device, comprising a base, a control box being provided on one side of the base; a positioning mechanism being provided on the top of the base, and a grinding component being provided on the top of the positioning mechanism;

[0008] The positioning mechanism includes a circular box fixedly installed on the top of the base, with a rotating shaft rotatably connected inside the circular box. A circular plate is fixedly installed on the outer top of the rotating shaft, and a worm gear is fixedly installed on the outer center of the rotating shaft. A worm is rotatably connected inside the circular box, and U-shaped plates are slidably connected inside the circular box. A movable rod is rotatably connected to the bottom of the circular plate away from the center, and the end of the movable rod away from the circular plate is rotatably connected to the U-shaped plate. A support plate is fixedly installed on the top of the circular box, and a sliding box is fixedly installed on one side of the top of the U-shaped plate. A sliding plate is inserted into the sliding box, and an arc-shaped toothed plate is fixedly installed on the side of the sliding plate away from the sliding box.

[0009] Preferably, fixed tubes are symmetrically embedded in the interior of both sides of the sliding box, and screws are threaded inside the fixed tubes. One end of the screw is rotatably connected to an insert block. Slots are symmetrically opened on both sides of the sliding plate, and the insert block is inserted into the slot.

[0010] Preferably, a guide rod is welded to one side of the sliding box, and one end of the guide rod passes through the support plate and is slidably connected to the support plate, and a stop block is fixedly connected to the end of the guide rod away from the sliding box.

[0011] Preferably, the grinding assembly includes support rods, all of which are symmetrically fixedly installed on the top of the base. A top plate is fixedly connected between the tops of the support rods, and an electric telescopic rod is fixedly installed inside the top plate. Sliding sleeves are slidably connected to the outside of the support rods, and a lifting plate is fixedly connected between the sliding sleeves. A grinding rod is rotatably connected inside the lifting plate. A housing is fixedly installed at the output end of the electric telescopic rod, and a servo motor is installed inside the housing. The top of the grinding rod is fixedly connected to the servo motor, and the bottom of the housing is fixedly connected to the lifting plate.

[0012] Preferably, a rotating block is fixedly installed at one end of the worm gear.

[0013] Preferably, the top side of the U-shaped plate passes through the support plate and is slidably connected to the support plate.

[0014] Preferably, the worm and the worm wheel are meshed together.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The gear inner ring processing device is specifically described as follows: By rotating the worm gear, the worm wheel rotates, and the rotation of the circular plate drives the rotation of multiple sets of movable rods. At this time, the inner teeth of the three arc-shaped tooth plates mesh with the outer surfaces of multiple sets of gears. The outer surfaces of the multiple sets of gears are squeezed and meshed to limit the movement, thereby achieving the effect of quickly clamping and positioning multiple sets of gears. This facilitates the subsequent grinding of the inner rings of the multiple sets of gears by the grinding rod, thus greatly improving the gear production and processing efficiency. Compared with the prior art of grinding the inner ring of a single gear, this method is more efficient. Furthermore, by using the meshing of teeth to position multiple sets of gears, the phenomenon of offset and falling off during grinding of multiple sets of gears can be effectively avoided, further improving the grinding quality of the gear inner ring. The operation of the electric telescopic rod drives the lifting plate to move longitudinally, and the servo motor drives the grinding rod to grind the inner ring of the gear, thereby achieving the effect of quickly grinding the inner rings of multiple sets of gears. This greatly improves the efficiency of continuous gear production and processing, and achieves a semi-automatic gear production and grinding effect.

[0016] 1. The operator rotates a worm gear, which in turn drives a rotating shaft. This shaft, in turn, drives a circular plate, which in turn drives multiple sets of movable rods. The rotation of these rods pulls a U-shaped plate to slide inside the circular box. When the U-shaped plates move closer together, they move the sliding box, slide plate, and arc-shaped toothed plate. At this point, the inner teeth of the three arc-shaped toothed plates mesh with the outer surfaces of multiple sets of gears. This external compression and meshing limit the multiple sets of gears, achieving positioning and initial grinding. This allows for rapid clamping and positioning of multiple sets of gears, facilitating subsequent grinding of the inner rings by the grinding rods. This significantly improves gear production efficiency compared to existing methods that grind the inner rings of individual gears, and utilizes tooth meshing to grind multiple sets of gears. Positioning the wheels effectively prevents gears from shifting or falling off during grinding, further improving the grinding quality of the gear inner ring. Workers insert the slide plate into the sliding box from top to bottom. Then, two sets of screws rotate inside the fixed tube. The rotation of the screws drives the rotation of the insert block, which slowly inserts into the slot. The insert block stops rotating due to friction until it is fully engaged with the slot. This allows for quick replacement and maintenance of the arc-shaped gear plate, facilitating the replacement of the appropriate arc-shaped gear plate according to the gear specifications and greatly improving the flexibility of the device. The movement of the sliding box drives three guide rods to slide inside the support plate. A stop block limits the guide rods, making the movement of the arc-shaped gear plate more stable and preventing instability in the fixing of the arc-shaped gear plate to the gear.

[0017] 2. The electric telescopic rod is driven by the operator's controller. The operation of the electric telescopic rod causes the lifting plate to move longitudinally. At this time, the movement of the lifting plate causes the four sliding sleeves to slide outside the support rod. Then, the lifting plate drives the grinding rod to insert into the inner ring of multiple gears. At this time, the operator operates the controller to drive the servo motor to run. The servo motor drives the grinding rod to grind the inner ring of the gears, thereby achieving the effect of quickly grinding the inner ring of multiple gears. This greatly improves the efficiency of continuous gear production and processing, and realizes the semi-automated production and grinding effect of gears. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides a technical solution: a gear inner ring processing device, including a base 1, a control box 101 is provided on one side of the base 1; a positioning mechanism 2 is provided on the top of the base 1, and a grinding component 3 is provided on the top of the positioning mechanism 2.

[0027] The positioning mechanism 2 includes a circular box 201 fixedly installed on the top of the base 1. A rotating shaft 202 is rotatably connected inside the circular box 201. A circular plate 203 is fixedly installed on the outer top of the rotating shaft 202. A worm gear 204 is fixedly installed on the outer center of the rotating shaft 202. A worm 205 is rotatably connected inside the circular box 201, meshing with the worm gear 204. U-shaped plates 206 are slidably connected inside the circular box 201. Movable rods 207 are rotatably connected to the bottom of the circular plates 203 on the side furthest from the center. The end of the movable rod 207 furthest from the circular plate 203 is rotatably connected to the U-shaped plate 206. A support plate 208 is fixedly installed on the top of the circular box 201. A support plate 208 is fixedly installed on one side of the top of the U-shaped plate 206. The U-shaped plate 206 is slidably connected to the support plate 208 and has a sliding box 209 fixedly installed on one side of its top. A slide plate 210 is inserted into the sliding box 209, and an arc-shaped toothed plate 211 is fixedly installed on the side of the slide plate 210 away from the sliding box 209. This enables the rapid clamping and positioning of multiple gears, facilitating the subsequent grinding of the inner rings of multiple gears by the grinding rod 306. This greatly improves the efficiency of gear production and processing, which is more efficient than the existing method of grinding the inner rings of a single gear. Furthermore, by using tooth meshing to position multiple gears, the phenomenon of gears shifting or falling off during grinding can be effectively avoided, further improving the grinding quality of the inner rings of the gears.

[0028] The sliding box 209 has symmetrically embedded fixing tubes 212 on both sides, and the fixing tubes 212 are threaded with screws 213. One end of the screws 213 is rotatably connected to the insert block 214. The sliding plate 210 has symmetrically opened slots 215 on both sides, and the insert block 214 is inserted into the slot 215. This enables the rapid replacement and maintenance of the arc-shaped toothed plate 211, making it convenient for staff to replace the appropriate arc-shaped toothed plate 211 according to the gear specifications, and greatly improving the flexibility of the device during use.

[0029] Guide rods 216 are welded to one side of the sliding box 209, and one end of the guide rod 216 passes through the support plate 208 and is slidably connected to the support plate 208. A stop block 217 is fixedly connected to the end of the guide rod 216 away from the sliding box 209. The movement of the sliding box 209 drives the three guide rods 216 to slide inside the support plate 208. At this time, the stop block 217 limits the guide rods 216, so that the movement of the arc-shaped toothed plate 211 is more stable and the arc-shaped toothed plate 211 is not unstable in fixing the gear. A rotating block 218 is fixedly installed at one end of the worm gear 205. The design of the rotating block 218 makes it easier for the operator to operate the worm gear 205.

[0030] The grinding assembly 3 includes support rods 301, which are symmetrically fixedly installed on the top of the base 1. A top plate 302 is fixedly connected between the tops of the support rods 301. An electric telescopic rod 303 is fixedly installed inside the top plate 302. A sliding sleeve 304 is slidably connected to the outside of the support rods 301. A lifting plate 305 is fixedly connected between the sliding sleeves 304. A grinding rod 306 is rotatably connected inside the lifting plate 305. A housing 307 is fixedly installed at the output end of the electric telescopic rod 303. A servo motor 308 is installed inside the housing 307. The top of the grinding rod 306 is fixedly connected to the servo motor 308, and the bottom of the housing 307 is fixedly connected to the lifting plate 305. This enables rapid grinding of multiple gear inner rings, greatly improving the efficiency of continuous gear production and achieving semi-automatic gear grinding. By replacing the grinding rod 306, the grinding rod 306 can be matched with the corresponding gear inner ring.

[0031] Working principle: Before using this gear inner ring machining device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, the operator first places the base 1 and control box 101 on the workbench, and uses the control box 101 to power and control the equipment. The operator then stacks multiple sets of gears of the same specification on top of the circular box 201. At this time, the operator rotates the worm gear 205, which drives the worm wheel 204 to rotate. The rotation of the worm wheel 204 drives the rotation of the rotating shaft 202, which in turn drives the rotation of the circular plate 203. The rotation of the circular plate 203 drives the rotation of multiple sets of movable rods 207. The rotation of the movable rods 207 pulls the U-shaped plate 206 to slide inside the circular box 201. When the worm gear 205 rotates in the opposite direction... At this time, the rotating rod 207 pushes the U-shaped plate 206 to unfold. When the U-shaped plates 206 approach and converge, they drive the sliding box 209, the sliding plate 210, and the arc-shaped toothed plate 211 to move. At this time, the inner teeth of the three arc-shaped toothed plates 211 mesh with the outer surfaces of multiple gears. The outer surfaces of the multiple gears are squeezed and meshed to limit their movement, thus achieving the positioning and initial grinding of the multiple gears. This enables the rapid clamping and positioning of multiple gears, facilitating the subsequent inner ring grinding of the gears by the grinding rod 306, thereby greatly improving the gear production and processing efficiency compared to existing methods. The current method of grinding the inner ring of a single gear is more efficient, and by using tooth meshing to position multiple sets of gears, it can effectively prevent the phenomenon of misalignment and falling off during the grinding of multiple sets of gears, further improving the grinding quality of the inner ring of the gear. The operator inserts the slide plate 210 into the sliding box 209 from top to bottom. At this time, the operator rotates the two sets of screws 213 inside the fixed tube 212. The rotation of the screws 213 drives the rotation and movement of the insert 214. At this time, the insert 214 slowly inserts into the slot 215. Then, the insert 214 stops rotating due to friction until the insert 214 stops rotating. The worm gear 211 is fully inserted into the slot 215, which enables quick replacement and maintenance of the arc-shaped toothed plate 211. This allows staff to easily replace the appropriate arc-shaped toothed plate 211 according to the gear specifications, greatly improving the flexibility of the device. The movement of the sliding box 209 drives the three guide rods 216 to slide inside the support plate 208. At this time, the stop block 217 limits the guide rods 216, which makes the movement of the arc-shaped toothed plate 211 more stable and avoids the arc-shaped toothed plate 211 being unstable in fixing the gear. The design of the rotating block 218 makes it easier for staff to operate the worm gear 205.

[0032] The electric telescopic rod 303 is driven by the operator's controller. The operation of the electric telescopic rod 303 causes the lifting plate 305 to move longitudinally. At this time, the movement of the lifting plate 305 causes the four sliding sleeves 304 to slide outside the support rod 301. Then, the lifting plate 305 drives the grinding rod 306 to insert into the inner ring of multiple gears. At this time, the operator operates the controller to drive the servo motor 308. The servo motor 308 drives the grinding rod 306 to grind the inner ring of the gears, thereby achieving the effect of quickly grinding the inner ring of multiple gears, which greatly improves the efficiency of continuous gear production and processing, and realizes the semi-automated production and grinding effect of gears.
