[0003] Chinese patent CN213380748U discloses a grinding device for the small end face of a floating oil seal. The nozzle is moved back and forth by a cylinder telescopically to blow and clean the grinding table and the workpiece. The device can be used for blowing and cleaning before clamping the oil seal, or for blowing and cooling during the grinding process to prevent the waste chips on the grinding table from damaging the end face and outer ring of the oil seal. After blowing and cleaning, the waste liquid with the waste chips flows away from the workpiece installation gap and is discharged through the drainage groove.

[0015] To achieve the above object, the present invention provides the following technical solution: a grinding device for intelligent manufacturing, comprising the following steps: First, the floating oil seal is placed from the placement port between the stacking plates for stacking, and the rotating rollers in the grinding processing box are driven to rotate counterclockwise to move the conveyor belts sleeved on the rotating rollers at both ends, thereby driving the placement plate on the conveyor belt to be transported in an orderly manner in the grinding processing box. When the conveyor belt drives the placement plate to enter along the bevel between the driving sliders on both sides, the driving sliders on both sides will be gradually pushed to both sides, and at the same time, the driven gear on the lower surface of the placement plate will contact and engage with the driving rack on the support frame, and the positioning locking assembly on the placement plate will be driven to retract to the middle position through the clockwise rotation of the driven gear. While the driving slider moves to both sides, it will drive the intermittent unloading assembly in the placement box to operate, so that the movable plates and driving sliders on both sides move to both sides at the same time, and a single floating oil seal is unloaded into the placement plate below.

[0016] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. By placing the floating oil seal between the stacking plates, the floating oil seal will push the stacking plates on both sides to move to both sides to squeeze the annular spring to adapt to floating oil seals of different sizes. Stacking the floating oil seals between the stacking plates can better adapt to different shapes and sizes, improve the stability and accuracy of clamping, and be able to handle oil seals of various sizes to improve production efficiency. By driving the placement disc on the conveyor belt to be transported in an orderly manner in the grinding processing box, the placement disc is contacted with the driving sliders on both sides, and the intermittent unloading component is driven to intermittently drop the stacked floating oil seals into the placement disc separately. Through orderly transportation, the waiting time can be reduced, the continuous operation of the grinding equipment can be ensured, and the overall production efficiency can be improved.

[0017] 2. After the placement plate with the floating oil seal is driven to pass between the driving sliders, the driving rack is no longer meshed with the driven gear. The stretched folded spring will pull the limit slider to slide along the directional slide groove under the reaction force, so that the three positioning blocks are moved out of the storage cover at the same time, and the inner ring wall of the floating oil seal in the placement plate is resisted at the same time, so that the floating oil seal is positioned and calibrated in the placement plate. Accurate positioning and calibration can ensure that the oil seal is in the correct position, thereby improving the quality of floating oil seal processing and effectively preventing the floating oil seal from accidentally falling off during the loading process.

[0018] 3. The output end of the motor drives the bevel gear 1 on the limit rod to rotate, so that the meshing bevel gear 2 drives the screw rod to rotate in the lifting frame, and drives the dividing plate screwed with the screw rod to adjust the lifting height. The linkage rod at one end of the sliding rack 2 drives the sliding shaft to slide in the adjusting slide groove, so that the interval between the dividing plate and the moving plate is the same as the height of the floating oil seal. Adjustment according to the size of the oil seal can ensure that the blanking assembly is perfectly matched with the floating oil seal, and can quickly adapt to oil seals of different sizes, reducing changeover time.

[0019] 4. By driving the moving plate in the placement box to expand to both sides, the moving plate drives the sliding rack one on one side to move together while moving. The movement of sliding rack one will drive the meshing coordination gear above to rotate. The rotation of the coordination gear will push sliding rack two to drive the dividing plate to insert into the chamfer of the floating oil seal port, and separate the stacked floating oil seals from the floating oil seals to be unloaded at the bottom. Intermittent unloading can effectively avoid collision and damage caused by unloading multiple pieces at the same time, protect the integrity of the oil seal, and single unloading can ensure more accurate positioning and placement of each oil seal, thereby improving the convenience of subsequent processing.

The driven gear 206 is in the interval between the conveyor belts 202 on both sides. A positioning locking component is fixedly connected to the driven gear 206. The positioning locking component is installed in the placement plate 203. The contact and meshing of the driving rack 205 and the driven gear 206 can drive the positioning locking component in the placement plate 203 to be recovered; An intermittent material discharging mechanism 300 is fixedly installed at one end of the grinding processing box 100, and the intermittent material discharging mechanism 300 includes a placement box 301 fixedly installed on one side of the grinding processing box 100, and a placement opening 302 is opened on the upper surface of the placement box 301. Annular spring pieces 303 are fixedly installed on both sides of the inner wall of the placement box 301, and a stacking plate 304 is fixedly installed on one end of the annular spring piece 303 away from the placement box 301. The stacking plate 304 is arranged below the placement opening 302, and floating oil seals 305 are stacked between the stacking plates 304.

The conveyor belt 202 drives the placement plate 203 to pass between the driving sliders 307, which will drive the floating oil seal 305 to unload from the moving plate 306. There are four rotating rollers 201, which are symmetrically installed on the inner wall of the grinding processing box 100. The middle part of the conveyor belt 202 is a hollow part. The two conveyor belts 202 are fixed by the placement plate 203. The upper and lower ends of the floating oil seal 305 are chamfered to facilitate subsequent intermittent unloading.

[0026] Specifically, the floating oil seal 305 is placed from the placement port 302 between the stacking plates 304 for stacking, and the rotating rollers 201 in the grinding processing box 100 are driven to rotate counterclockwise, so that the conveyor belt 202 sleeved on the rotating rollers 201 at both ends moves, and the placement plate 203 on the conveyor belt 202 is transported in an orderly manner in the grinding processing box 100. When the conveyor belt 202 drives the placement plate 203 to enter along the bevel between the driving sliders 307 on both sides, the driving sliders 307 on both sides are gradually moved to the grinding processing box 100. Pushed from both sides, the driven gear 206 on the lower surface of the placement plate 203 will contact and mesh with the driving rack 205 on the support frame 204, and the positioning locking assembly on the placement plate 203 will be retracted to the middle position through the clockwise rotation of the driven gear 206. While the driving slider 307 moves to both sides, it will drive the intermittent unloading assembly in the placement box 301 to operate, so that the movable plates 306 and the driving slider 307 on both sides move to both sides at the same time, and unload the single floating oil seal 305 into the placement plate 203 below.

[0027] By placing the floating oil seal 305 between the stacking plates 304, the floating oil seal 305 will push the stacking plates 304 on both sides to move to both sides to squeeze the annular spring piece 303 to adapt to floating oil seals 305 of different sizes. Stacking the floating oil seal 305 and placing it between the stacking plates 304 can better adapt to different shapes and sizes, improve the stability and accuracy of clamping, and be able to handle oil seals of various sizes, thereby improving production efficiency. By driving the placement plate 203 on the conveyor belt 202 to be transported in an orderly manner in the grinding processing box 100, the placement plate 203 is brought into contact with the driving sliders 307 on both sides, and the intermittent unloading component is driven to intermittently drop the stacked floating oil seals 305 into the placement plate 203 individually. Through orderly transportation, the waiting time can be reduced, the continuous operation of the grinding equipment can be ensured, and the overall production efficiency can be improved.

There are three transmission rods 210. One end of the transmission rod 210 away from the rotating seat 207 is rotatably connected with a positioning block 211. The lower surface of the positioning block 211 is fixedly connected with a limiting slider 212.

When the limiting slider 212 slides along the directional slide groove 213 into the storage cover 215, the folded spring piece 214 on one side of the limiting slider 212 will be pulled to a straight state, so that the positioning block 211 above the limiting slider 212 is recovered into the storage cover 215. At the same time, the placement plate 203 is completely moved to the center of the driving slider 307, and intermittent unloading is performed.

Grooves are provided on both sides of the limit rod 316, and protrusions are fixedly connected on both sides of the center hole of the bevel gear 1 317. When the limit rod 316 rotates, the bevel gear 1 317 can be driven to rotate at the same time through the cooperation of the groove and the protrusion. When the sliding rack 2 310 moves, the limit rod 316 can slide through the center hole of the bevel gear 1 317.

[0036] A screw rod 319 is fixedly connected to the upper surface of the bevel gear 318. The end of the screw rod 319 away from the bevel gear 318 is rotatably connected to the lifting frame 320.

When the placing plate 203 on the conveyor belt 202 is driven by the rotating roller 201 to pass between the driving sliders 307 on both sides, the placing plate 203 will move along the oblique edge of the driving slider 307, and the driving slider 307 will move to the two sides. The sliding plate 306 in the placement box 301 is gradually pushed from side to side, and the driving slider 307 moves to both sides, while driving the moving plate 306 to expand to both sides. The moving plate 306 drives the sliding rack 1 308 on one side to move together. The movement of the sliding rack 1 308 drives the meshing coordination gear 309 above to rotate. The rotation of the coordination gear 309 drives the sliding rack 2 310 to drive the dividing plate 311 to insert into the chamfer of the port of the floating oil seal 305, and separates the stacked floating oil seal 305 from the floating oil seal 305 that is about to be unloaded at the bottom. The floating oil seal 305 located between the dividing plate 311 and the moving plate 306 completes a single intermittent unloading when the moving plate 306 expands and opens to both sides.
