Description

Technical Field

[0001] The utility model relates to the technical field of grinding and polishing, in particular to a single-side grinding and polishing integrated device. Background Art

[0002] A grinder is a machine that grinds the surface of a workpiece with a grinding disc coated with or embedded with abrasives; a polisher is a grinding tool that uses a polishing disc and a polishing agent to rub the surface of the workpiece to remove paint contamination, oxide layer, and shallow marks; since the processing principles of grinders and polishers are very similar, grinders and polishers are usually integrated with each other to form an all-in-one machine. When using it, you only need to select the grinding disc or polishing disc according to the processing requirements and adjust the speed of the grinding disc or polishing disc; depending on whether the upper and lower end faces of the workpiece can be processed at the same time, the grinding and polishing machine can be divided into a single-sided grinding and polishing machine and a double-sided grinding and polishing machine.

[0003] In order to increase the number of workpieces that can be processed in a single operation by the grinding and polishing machine, the simplest way is to increase the area of ​​the grinding disc or the polishing disc, which results in a larger overall size of the existing grinding and polishing machines on the market. In addition, since the feeding and unloading of most grinding and polishing machines still need to be done manually, the operator must constantly change the position where he stands when feeding and unloading, so that the workpiece can be quickly placed on the vacant position on the grinding disc or the polishing disc or the workpiece after grinding or polishing can be removed from the grinding disc or the polishing disc. Moreover, the workpieces removed from different positions need to be put together, which makes it extremely inconvenient to use, time-consuming and laborious. To solve the above problems, the only way is to increase the number of staff to arrange an operator at different positions of the grinding and polishing machine, but this will lead to an increase in labor costs, which in turn will cause an increase in processing costs, which urgently needs to be solved.

[0010] When the outer wall of the outer driven wheel in each conversion unit does not contact the outer wall of the corresponding conversion sleeve, each conversion sleeve will follow the grinding disc or polishing disc to revolve around the inner driven wheel by the friction between itself and the grinding disc or polishing disc during the rotation of the grinding disc or polishing disc;

[0011] When the outer wall of the outer driven wheel in each conversion unit fits against the outer wall of the corresponding conversion sleeve, each conversion sleeve will be blocked by the corresponding outer driven wheel to stop the revolution during the rotation of the grinding disc or the polishing disc, and utilize the principle that the linear speed of the grinding disc or the polishing disc increases radially from the inside to the outside during circular rotation to generate torque, and then rotate under the rolling limit action of the inner driven wheel and the corresponding outer driven wheel.

[0012] Preferably, the pressing mechanism includes a pressing cylinder fixed on the frame and a pressure plate which is laterally arranged and rotatably concentrically connected to the telescopic end of the pressing cylinder. The telescopic end of the pressing cylinder is arranged vertically downward, and the outer diameter of the pressure plate cooperates with the inner diameter of the conversion sleeve.

[0013] Preferably, a plurality of ceramic columns evenly arranged at equal angles along the circumferential direction are fixed to the bottom of the conversion sleeve, and the end of each ceramic column is slidably fitted on the top outer wall of the grinding disc or the polishing disc.

[0014] Preferably, the locking mechanism further includes a stopper fixed to the top of the base and located on one side of the swing arm.

[0024] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0025] like Figures 1 to 4 As shown, a single-sided grinding and polishing integrated device includes a body 1, a base 3 fixed on the top of the body 1, a frame 2 fixed above the body 1, and a driving mechanism arranged on the body 1, and a circular sinking cavity 31 is opened on the top of the base 3.

[0026] The driving mechanism includes a traction plate 4 which is laterally arranged and rotatably connected to the circular sink cavity 31 and a reduction motor 5 fixed to the bottom of the base 3. The rotating shaft of the reduction motor 5 vertically passes through the base 3 and is concentrically fixed to the bottom of the traction plate 4.

[0027] The driving mechanism also includes a grinding disc or polishing disc 6 which is concentrically and detachably fixed on the top of the traction disc 4 and located in the circular sink cavity 31 , and an inner driven wheel 10 which is concentrically and rotatably connected to the top of the grinding disc or polishing disc 6 .

[0028] The periphery of the inner driven wheel 10 is also provided with a plurality of conversion units distributed in sequence along the circumferential direction. Correspondingly, the top of the grinding disc or polishing disc 6 is also provided with the same number of conversion sleeves 9, and each conversion sleeve 9 is laterally and movably arranged between the outer wall of the inner driven wheel 10 and the inner wall of the circular sinking cavity 31.

[0029] The conversion unit includes a pressing mechanism 8 arranged on the frame 2 and a locking mechanism 7 arranged on the base 3; the locking mechanism 7 includes a rotating cylinder 71 fixed on the top of the base 3, a swing arm 72 laterally fixed on the rotating end of the rotating cylinder 71, and an external driven wheel 73 laterally arranged and rotatably connected to the end of the swing arm 72, and the rotating end of the rotating cylinder 71 is arranged vertically upward or downward.

[0030] When the outer wall of the outer driven wheel 73 in each conversion unit is not in contact with the outer wall of the corresponding conversion sleeve 9, each conversion sleeve 9 will follow the grinding disc or polishing disc 6 to revolve around the inner driven wheel 10 during the rotation of the grinding disc or polishing disc 6 by relying on the friction between itself and the grinding disc or polishing disc 6.

[0031] When the outer wall of the outer driven wheel 73 in each conversion unit fits with the outer wall of the corresponding conversion sleeve 9, each conversion sleeve 9 will be blocked by the corresponding outer driven wheel 73 to stop the revolution during the rotation of the grinding disk or polishing disk 6, and the torque is generated by utilizing the principle that the linear speed of the grinding disk or polishing disk 6 increases radially from the inside to the outside during circular rotation, and then the conversion sleeve 9 rotates under the rolling limit action of the inner driven wheel 10 and the corresponding outer driven wheel 73.

[0032] The pressing mechanism 8 includes a pressing cylinder 81 fixed on the frame 2 and a pressure plate 82 which is laterally arranged and rotatably connected concentrically to the telescopic end of the pressing cylinder 81. The telescopic end of the pressing cylinder 81 is arranged vertically downward, and the outer diameter of the pressure plate 82 cooperates with the inner diameter of the conversion sleeve 9.

[0033] The bottom of the conversion sleeve 9 is also fixed with multiple ceramic columns 11 evenly arranged at equal angles along the circumferential direction. The end of each ceramic column 11 slides and fits on the top outer wall of the grinding disk or polishing disk 6, thereby preventing the bottom of the conversion sleeve 9 from directly contacting the grinding disk or polishing disk 6, thereby avoiding wear on the bottom of the conversion sleeve 9 and extending its service life.

[0034] The locking mechanism 7 further includes a stopper 74 fixed to the top of the base 3 and located on one side of the swing arm 72 .

[0035] A laterally distributed limiting ring 12 is also provided inside the conversion sleeve 9 . One side of the limiting ring 12 is detachably fixed to the inner wall of the conversion sleeve 9 and the fixed height can be adjusted up and down. The top of the limiting ring 12 is lower than the top opening of the conversion sleeve 9 .

[0036] The inner edge of the top opening of the conversion sleeve 9 is also formed with a chamfered surface 93 arranged circumferentially.

[0037] A vertically distributed limiting groove 91 is formed on the inner wall of the conversion sleeve 9 , and correspondingly, a vertically arranged connecting piece 13 is fixed on the outer wall of one side of the limiting ring 12 , and the connecting piece 13 is movably embedded in the limiting groove 91 .

[0038] A threaded hole 92 is formed on the inner wall of the limiting groove 91 , and correspondingly, a vertical slot 131 is formed in the connecting piece 13 . Laterally distributed screws 14 are inserted into the slot 131 , and the threaded ends of the screws 14 are inserted and screwed into the threaded hole 92 .

[0039] A material tray 14 is also fixed to the front side of the base 3 .

[0040] Working principle:

[0041] Step 1: The operator stands in front of the machine body 1 and temporarily places the workpiece to be processed on the swing tray 14; then drives the telescopic ends of the pressing cylinder 81 in the pressing mechanism 8 in each conversion unit to retract inward to drive each pressure plate 82 to move up to the top of a corresponding conversion sleeve 9.

[0042] Step 2: The operator sequentially places each workpiece to be processed into the interior of the limiting ring 12 in the conversion sleeve 9 closest to him / her, and adjusts the height of the limiting ring 12 to a position lower than the top of the workpiece.

[0043] Step three: driving the rotating end of the rotary cylinder 71 in the locking mechanism 7 in each conversion unit to rotate a certain angle to drive each outer driven wheel 73 to move away from a corresponding conversion sleeve 9 .

[0044] Step 4: Start the reduction motor 5 to rotate its rotating shaft by a certain angle to drive the grinding disc or polishing disc 6 to rotate synchronously with the help of the traction disc 4, thereby driving each conversion sleeve 9 to revolve in the direction of the positioning mechanism 7 in a conversion unit located on its downstream side.

[0045] Step 5: When each conversion sleeve 9 rotates to between two adjacent locking mechanisms 7, the rotating end of the rotating cylinder 71 in the locking mechanism 7 in each conversion unit is driven to reverse until the swing arm 72 is blocked by the block 74; at this time, the minimum distance between the outer wall of each outer driven wheel 73 and the outer wall of the inner driven wheel 10 is smaller than the outer diameter of the conversion sleeve 9, so when each conversion sleeve 9 revolves between the nearest outer driven wheel 73 and the inner driven wheel 10, each conversion sleeve 9 will be blocked by the nearest outer driven wheel 73 and stop, so that a conversion sleeve 9 with a workpiece placed on it will leave the operator, and at the same time, a conversion sleeve 9 on the upstream side without a workpiece placed on it will rotate to the vicinity of the operator, and then the operator can continue to place each workpiece to be processed into the inner limit ring 12 of the conversion sleeve 9 that has just rotated to the vicinity of itself.

[0046] Step 6: Repeat steps 3, 4 and 5 until a certain number of workpieces to be processed are placed inside the limit ring 12 in each conversion sleeve 9. This allows the operator to place a certain number of workpieces to be processed in each conversion sleeve 9 in turn to complete the feeding without changing his or her standing position, which saves time and labor.

[0047] Step seven: Drive the telescopic ends of the pressing cylinder 81 in the pressing mechanism 8 in each conversion unit to extend outward to drive each pressure plate 82 to move down to the inside of a corresponding conversion sleeve 9, until the end face of each pressure plate 82 is pressed tightly against the top of each workpiece to be processed to apply pressure to each workpiece to be processed, while also preventing the conversion sleeve 9 from shifting; the setting of the chamfered surface 93 is conducive to each pressure plate 82 to smoothly, quickly and accurately enter the inside of each corresponding conversion sleeve 9.

[0048] Step 8: Start the reduction motor 5 to make its rotating shaft rotate continuously. At this time, each conversion sleeve 9 cannot revolve. Since the linear velocity of the circumferential rotation of any position on the conversion sleeve 9 gradually increases from the inside to the outside, that is, the linear velocity of the circumferential rotation of the grinding disc or polishing disc 6 at the innermost position of the conversion sleeve 9 is the smallest, and the linear velocity of the circumferential rotation of the grinding disc or polishing disc 6 at the outermost position of the conversion sleeve 9 is the largest; due to the above principle, the grinding disc or polishing disc 6 will generate a torque forcing each conversion sleeve 9 in revolution to rotate, and since the outer wall of each outer driven wheel 73 at this time rolls and fits the outer wall of a corresponding conversion sleeve 9, and the outer wall of the inner driven wheel 10 rolls and fits the outer wall of each conversion sleeve 9, when the above torque value is greater than the friction between each conversion sleeve 9 and the grinding disc or polishing disc 6, each conversion sleeve 9 will start to rotate, thereby causing the rotating grinding disc or polishing disc 6 to grind or polish each workpiece located in the conversion sleeve 9. In this process, each pressure plate 82 will also passively follow the corresponding conversion sleeve 9 to rotate in time.

[0049] Step nine: After grinding or polishing, first drive the telescopic ends of the pressing cylinder 81 in the pressing mechanism 8 in each conversion unit to retract inward to drive each pressure plate 82 to move up to the top of the corresponding conversion sleeve 9; then the operator first takes out the workpieces in the conversion sleeve 9 closest to him / herself in turn; then repeat steps three, four and five until the workpieces in each conversion sleeve 9 are taken out, which enables the operator to complete the workpiece unloading without changing his / her standing position, saving both time and labor.

[0050] The utility model divides the processing area of ​​the grinding and polishing machine into multiple operating stations that can be switched in turn with the help of multiple conversion units and multiple conversion sleeves 9 that cooperate with each other, so that the operator can complete the feeding and unloading of the workpiece without changing the standing position, and avoids the removal of the workpieces from being scattered, thereby greatly facilitating the use and achieving the effect of saving time and effort; and there is no need to increase manpower, and only one operator can complete it in an orderly manner, thereby preventing the increase in labor costs and reducing processing costs; in addition, the utility model does not need to add other power equipment or manipulators, and only the reduction motor 5 that drives the grinding disc or polishing disc 6 to rotate can drive the revolution of multiple conversion sleeves 9, and with the help of the passively rotating inner driven wheel 10 and the outer driven wheel 73, the linear speed difference principle of circular rotation can be used to drive each conversion sleeve 9 to revolve, thereby effectively controlling the manufacturing cost and taking into account economy.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
