Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
In order to solve the problems that in the background technology, if the inner hole of the grinding wheel is smaller than the outer diameter of the fixing piece, the grinding wheel is forcibly sleeved on the fixing piece, and the grinding wheel is easy to be heated and burst.
As shown in fig. 1 to 8, the present invention provides an embodiment of a five-axis numerical control grinding apparatus.
Specifically, the structure of the five-axis numerical control grinding device comprises a grinding wheel fixing mechanism arranged at the driving end of the grinding machine tool body 91; the grinding wheel fixing mechanism comprises a main fixing sleeve 1 sleeved on the side wall of the driving end of the grinding machine body 91 and an auxiliary fixing sleeve 2 connected with the main fixing sleeve 1, wherein the auxiliary fixing sleeve 2 is detachably connected with the driving end of the grinding machine body 91;
the main fixing sleeve 1 can penetrate into the inner hole of the grinding wheel and limit the grinding wheel sleeved on the outer side of the main fixing sleeve 1, the auxiliary fixing sleeve 2 is arranged at one end of the main fixing sleeve 1 penetrating through the inner hole of the grinding wheel, a plurality of mounting grooves 3 are formed in the end face of one end, close to the auxiliary fixing sleeve 2, of the main fixing sleeve 1, and inner hole avoiding grooves 4 are formed in the side wall of one end, close to the auxiliary fixing sleeve 2, of the main fixing sleeve 1;
the hollow plug heads 5 are arranged in all the mounting grooves 3, return elastic pieces 6 are arranged at one end, far away from the inner hole avoidance groove 4, of each hollow plug head 5, a lower pressing block 7 is arranged at one end, far away from the return elastic pieces 6, of each hollow plug head 5, all the lower pressing blocks 7 are arranged in the inner hole avoidance groove 4, jacking columns 8 are sleeved in each hollow plug head 5, and the return elastic pieces 6 can respectively provide supporting force for the hollow plug heads 5 and the jacking columns 8;
the lower pressing block 7 can be pushed by the inner hole of the grinding wheel to move towards the axial line direction of the main fixing sleeve 1 and push the corresponding hollow plug head 5 to press the return elastic piece 6, and the jacking column 8 can slide out of the hollow plug head 5 when the lower pressing block 7 moves towards the axial line direction of the main fixing sleeve 1.
In this embodiment, as shown in fig. 4, all the pressing blocks 7 are annular, and the return elastic member 6 is used for supporting and fixing the position of the hollow plug 5, so that the hollow plug 5 cannot easily move under the action of no external force.
Meanwhile, in this embodiment, the return spring 6 can provide supporting forces for the hollow plug 5 and the jack-up column 8 respectively, so that when the hollow plug 5 is pressed, the jack-up column 8 is not pressed, but is supported and kept at the initial position by the supporting force provided by the return spring 6.
According to the invention, through the cooperation of the plurality of lower pressing blocks 7 and the plurality of jacking columns 8, the action of limiting the grinding wheel with smaller inner hole diameter is realized, in particular, the main fixing sleeve 1 is directly inserted into the inner hole of the grinding wheel, then, due to the existence of the inner hole avoiding groove 4, the inner wall of the inner hole of the grinding wheel is not directly contacted with the side wall of the main fixing sleeve 1, but is contacted with all the lower pressing blocks 7, at the moment, if the inner diameter of the inner hole of the grinding wheel is smaller, all the lower pressing blocks 7 are simultaneously pushed by the inner hole of the grinding wheel to move towards the axial lead direction of the main fixing sleeve 1 and press the corresponding hollow plug 5 to press the return elastic piece 6, and then, the jacking columns 8 slide out of the hollow plug 5 when the lower pressing blocks 7 move towards the axial lead direction of the main fixing sleeve 1, so that the grinding wheel is limited, and the grinding wheel is prevented from sliding through the inner hole avoiding groove 4 and is directly sleeved on the side wall of the main fixing sleeve 1.
If the inner diameter of the inner hole of the grinding wheel is smaller, although the inner hole avoiding groove 4 can prevent the inner hole of the grinding wheel from directly contacting with the outer side wall of the main fixing sleeve 1 when penetrating the outer side of the main fixing sleeve 1 (namely avoiding the inner wall of the inner hole of the grinding wheel), the inner hole avoiding groove 4 is internally provided with the lower pressing block 7, so that the phenomenon that the end part of the lower pressing block 7 props against the edge of the inner hole of the grinding wheel can occur in the penetrating process of the grinding wheel, and therefore, the main fixing sleeve 1 preferably comprises a sleeve joint cylinder 11 and a fixing disc 12 which are sequentially arranged along the penetrating direction of the inner hole of the grinding wheel, and the inner hole avoiding groove 4 is arranged on the side wall of one end of the sleeve joint cylinder 11 far away from the fixing disc 12;
the end of the lower pressing block 7, which is far away from the main fixing sleeve 1, is provided with a leading-in cambered surface 13, and the surface of the lower pressing block 7 is flush with the outer side wall of the sleeve joint barrel 11.
When the grinding wheel inner hole is required to be penetrated outside the main fixing sleeve 1, the grinding wheel inner hole can be directly guided to be close to one end of the sleeve 11 far away from the fixing disc 12, and at the moment, because the inner hole avoidance groove 4 is arranged on one end side wall of the sleeve 11 far away from the fixing disc 12, the grinding wheel inner hole is not directly contacted with the end side wall of the sleeve 11 but contacted with all the lower pressing blocks 7, and when the grinding wheel inner hole is contacted with all the lower pressing blocks 7, due to the existence of the guiding cambered surface 13, the lower pressing blocks 7 cannot prop against the edge of the grinding wheel inner hole and block penetration of the grinding wheel, and a specific operation flow is (illustrated by one lower pressing block 7 here), when the edge of the grinding wheel inner hole contacts the lower pressing blocks 7, the edge of the grinding wheel inner hole slides along the guiding cambered surface 13 and gradually applies a lower pressure to the lower pressing blocks 7, so that the lower pressing blocks 7 move towards the axial line direction of the main fixing sleeve 1 (the specific movement direction of the lower pressing blocks 7 is perpendicular to the axial line direction of the main fixing sleeve 1).
For the purpose of providing supporting force to the hollow plug 5 and the jack-up column 8, respectively, it is preferable that the return spring 6 includes a mounting cover 61 connected in the mounting groove 3, a supporting air bag 62 is provided in the mounting cover 61, an excluder 63 fixedly connected with the hollow plug 5 is mounted on a surface of the supporting air bag 62, and a push-out bag 64 fixedly connected with an end portion of the jack-up column 8 is mounted in the supporting air bag 62.
In this embodiment, the supporting air bag 62 and the pushing-out air bag 64 are both filled with air, and the block 63 is provided with a slot at a position corresponding to the pushing-out air bag 64 as shown in fig. 8, and referring to fig. 7, the pushing-out air bag 64 has a certain movement space and does not move together with the supporting air bag 62.
In the prior art, the types of return spring pieces 6 for respectively providing supporting force for the hollow plug 5 and the jack-up column 8 can be more, for example, the annular sleeve type elastic pieces can be directly arranged (for example, two springs sleeved together are arranged, an inner spring is connected with the jack-up column 8, and the outer side is connected with the hollow plug 5), but the phenomenon that the lower pressing block 7 is inclined easily occurs, so that the lower pressing block 7 in the inner hole of the grinding wheel cannot be fully attached to the inner wall of the inner hole of the grinding wheel, and the return spring pieces 6 provided in the embodiment can ensure that the lower pressing block 7 can be always attached to the inner wall of the inner hole of the grinding wheel.
When the lower pressing block 7 moves toward the axial line direction of the main fixing sleeve 1, the hollow plug 5 corresponding to the lower pressing block 7 is pushed, so that the pushing block 63 slides along the inner wall of the mounting cover 61 and compresses the supporting air bag 62, so that the supporting air bag 62 moves toward the bottom of the mounting cover 61, but the pushing-out bag 64 is not compressed integrally, but other parts corresponding to the clamping grooves are compressed (taking fig. 7 as an example, the top edge of the pushing-out bag 64 is pressed, so that the top of the pushing-out bag 64 bulges, and other parts are compressed).
That is, when the lower pressing block 7 moves toward the axial line direction of the main fixing cover 1, the jack-up column 8 supported by the push-out pocket 64 gradually protrudes out of the hollow plug 5 (the reason why the jack-up column 8 gradually protrudes out of the hollow plug 5 is that the top of the push-out pocket 64 is bulged at this time, the height of the support air pocket 62 gradually decreases, so that the jack-up column 8 is pushed by the bulged push-out pocket 64, thereby causing the jack-up column 8 to protrude out of the hollow plug 5) to limit the grinding wheel.
Sometimes, the difference between the inner diameter of the inner hole of the grinding wheel and the diameter of the outer side of the sleeve 11 is not great (that is, the inner diameter of the inner hole of the grinding wheel is smaller than the diameter of the outer side of the sleeve 11, but insufficient for enabling the jacking column 8 to extend out of the hollow plug 5 to limit the grinding wheel), that is, the diameter of the lower pressing block 7 pushed by the inner hole of the grinding wheel to descend is smaller, and the purpose of limiting the grinding wheel cannot be met, so that preferably, an air guide groove 71 is formed in the position, corresponding to the hollow plug 5, of the surface of the lower pressing block 7, an air leakage groove 72 is formed in the inner side wall of the air guide groove 71, a pressing sheet 73 fixedly connected with the jacking column 8 is arranged in the air guide groove 71, and air in the push-out bag 64 can be guided between the jacking column 8 and the inner side wall of the hollow plug 5;
the end of the jack-up column 8 remote from the presser 73 is provided with a piercing head 74 capable of piercing the push-out capsule 64.
When the difference between the inner diameter of the inner hole of the grinding wheel and the outer diameter of the sleeve 11 is not large (in this case, the inner diameter of the inner hole of the grinding wheel is smaller than the outer diameter of the sleeve 11, but insufficient to enable the jack-up post 8 to extend out of the hollow plug head 5 to limit the grinding wheel), once the inner wall of the inner hole of the grinding wheel slides along the lower pressing block 7 and approaches the jack-up post 8, the inner wall of the inner hole of the grinding wheel contacts the pressing piece 73 first and presses the pressing piece 73 into the air guide groove 71 (because the inner diameter of the inner hole of the grinding wheel is smaller than the outer diameter of the sleeve 11, and when the inner wall of the inner hole of the grinding wheel contacts the pressing piece 73, the pressing piece 73 is pushed to move).
The pressing piece 73 entering the air guiding groove 71 pushes the jack-up column 8 to press the push-out bag 64, and when the jack-up column 8 presses the push-out bag 64, the pricking head 74 pierces the push-out bag 64, so that the air in the push-out bag 64 is discharged, and the discharged air enters the air guiding groove 71 along the gap between the jack-up column 8 and the inner side wall of the hollow plug 5 and is discharged along the air discharging groove 72.
When the grinding wheel slides along the lower pressing block 7 to be in contact with the sleeve 11, the grinding wheel is easy to clamp on the side wall of the sleeve 11 once the force is applied too hard, so that an operator mistakenly thinks that the matching is not problematic, and in order to avoid the phenomenon, the inner side wall of the mounting groove 3 is preferably provided with a deep groove 31;
the side wall of the push-out bag 64 is provided with an extension 641 penetrating through the mounting cover 61 and extending into the slot 31, the surface of the extension 641 is provided with an extension post 642, the extension post 642 can penetrate into the inner wall of the slot 31 and limit the grinding wheel sliding along the sleeve 11, the surface of the extension 641 is provided with a plurality of blocking posts 643 communicated with the extension 641, and the blocking posts 643 are used for applying a pulling force to the extension post 642.
In this embodiment, through holes corresponding to the protruding posts 642 are provided in the inner wall of the deep groove 31 to guide the protruding posts 642 to protrude.
Once the gas in the push-out bladder 64 is exhausted, the blocking post 643 is no longer in an inflated state (because the blocking post 643 is in communication with the push-out bladder 64 via the extension 641), that is, the pulling force exerted by the protruding post 642 is reduced, so that the protruding post 642 can penetrate through the inner wall of the deep groove 31 and limit the amount of grinding wheel sliding along the socket 11.
Further optimized for the protruding post 642: the extending column 642 comprises a fixed column 651 arranged on the surface of the extending section 641, a sliding cylinder 652 is sleeved on the outer side of the fixed column 651, a pull-back piece 653 connected with the sliding cylinder 652 is fixedly sleeved on the side wall of the fixed column 651, a hook ring 654 is arranged at one end, close to the extending section 641, of the sliding cylinder 652, the hook ring 654 can be hooked by the blocking column 643, and a through blocking column 655 is connected at one end, far away from the extending section 641, of the sliding cylinder 652.
Further optimized for the blocking post 643: the blocking post 643 includes a balloon post 661 in communication with the extension 641, the balloon post 661 having a groove 662 thereon for mating with the hook ring 654, the gas within the balloon post 661 being capable of entering the push-out balloon 64 along the extension 641.
In this embodiment, the pullback member 653 may be a tension spring.
When the air in the push-out bag 64 is exhausted, the air bag column 661 collapses and contracts to be in a full expansion state, that is, the groove 662 can not clamp the hook ring 654, and then the pull-back piece 653 pulls the sliding cylinder 652 to slide along the side wall of the fixed column 651, at this time, the sliding cylinder 652 pushes the through baffle post 655 to penetrate through the inner wall of the deep groove 31 and limit the grinding wheel sliding along the sleeve 11.
The side wall of the push-out bladder 64 is provided with an expansion groove 671, and the end of the push-out bladder 64 near the jack-up column 8 is provided with a sheet 672. The expansion groove 671 is provided so that the gas inside the push-out bag 64 expands along the expansion groove 671 when the push-out bag 64 is compressed, and the gas inside the push-out bag 64 also expands the push-out bag 64 when the push-out bag 64 is compressed, specifically, the sheet 672 is inflated, and then the inflated sheet 672 is lifted up against the jack post 8.
When the grinding wheel works, in order to prevent the inner hole from avoiding the groove 4 from affecting the grinding wheel sleeved on the side wall of the sleeve 11 (the inner hole is avoided from avoiding the groove 4 to generate gaps, so that the grinding wheel is easy to shake), the auxiliary fixing sleeve 2 is preferably provided with a movable disc 21 which is detachably and fixedly connected with the driving end of the grinding machine body 91, and a matching ring piece 22 matched with the inner hole avoiding groove 4 is arranged on the surface of one side of the movable disc 21, which is close to the sleeve 11.
After the grinding wheel is sleeved on the sleeve 11, the matching ring piece 22 is inserted into the inner hole avoiding groove 4, and then the movable disc 21 is detachably and fixedly connected with the driving end of the grinding machine tool body 91 through bolts.
The five-axis numerical control grinding equipment provided by the invention further comprises a base 9, wherein the base 9 is provided with a grinding machine tool body 91, and the driving end of the grinding machine tool body 91 is connected with a grinding wheel fixing mechanism.
As shown in fig. 2, the driving end of the grinding machine body 91 is connected with a grinding wheel fixing mechanism, and when the grinding machine is operated, the driving end of the grinding machine body 91 is directly started, so that the grinding wheel can be driven to perform machining operation.
The operation of the present invention is described in detail below with reference to fig. 1-8.
When in use, the main fixing sleeve 1 is directly inserted into the grinding wheel inner hole (in actual operation, the main fixing sleeve 1 is sleeved on the driving end of the grinding machine body 91, and then the grinding wheel inner hole is sleeved on the main fixing sleeve 1, so that the main fixing sleeve 1 is inserted into the grinding wheel inner hole relatively speaking).
Specifically, the grinding wheel inner hole is directly guided to be close to one end of the sleeve 11 far away from the fixed disc 12, and at this time, the inner hole avoidance groove 4 is arranged on one end side wall of the sleeve 11 far away from the fixed disc 12, so that the grinding wheel inner hole is not directly contacted with the end side wall of the sleeve 11, but is contacted with all the pressing blocks 7, and when the grinding wheel inner hole is contacted with all the pressing blocks 7, the pressing blocks 7 do not prop against the edge of the grinding wheel inner hole and block the penetration of the grinding wheel due to the existence of the guiding cambered surface 13.
The specific operational procedure is (illustrated here as a press block 7).
When the edge of the inner hole of the grinding wheel contacts the lower pressing block 7, the edge of the inner hole of the grinding wheel presses the lower pressing block 7 along the guiding cambered surface 13, so that the lower pressing block 7 moves towards the axial line direction of the main fixing sleeve 1.
When the lower pressing block 7 moves toward the axial line direction of the main fixing sleeve 1, the hollow plug head 5 corresponding to the lower pressing block 7 is pushed, so that the pushing block 63 slides along the inner wall of the mounting cover 61 and compresses the supporting air bag 62, so that the supporting air bag 62 moves toward the bottom of the mounting cover 61, but the pushing-out bag 64 is not compressed integrally, but other parts corresponding to the clamping groove are compressed. That is, when the lower pressing block 7 moves toward the axial line direction of the main fixing sleeve 1, the top of the push-out bag 64 expands and pushes up the jack-up column 8 in the hollow plug 5, so that the jack-up column 8 gradually protrudes out of the hollow plug 5 to limit the grinding wheel.
When the difference between the inner diameter of the inner hole of the grinding wheel and the outer diameter of the sleeve 11 is not large (in this case, the inner diameter of the inner hole of the grinding wheel is smaller than the outer diameter of the sleeve 11, but insufficient for the jack-up post 8 to extend out of the hollow plug head 5 to limit the grinding wheel), once the inner wall of the inner hole of the grinding wheel slides along the lower pressing block 7 and approaches the jack-up post 8, the inner wall of the inner hole of the grinding wheel is contacted with the pressing piece 73 first and presses the pressing piece 73 into the air guide groove 71.
The pressing piece 73 entering the air guiding groove 71 pushes the jack-up column 8 to press the push-out bag 64, and when the jack-up column 8 presses the push-out bag 64, the pricking head 74 pierces the push-out bag 64, so that the air in the push-out bag 64 is discharged, and the discharged air enters the air guiding groove 71 along the gap between the jack-up column 8 and the inner side wall of the hollow plug 5 and is discharged along the air discharging groove 72.
Once the gas in the push-out bladder 64 is exhausted, the blocking post 643 is no longer in an inflated state (because the blocking post 643 is in communication with the push-out bladder 64 through the extension 641), that is, when the gas in the push-out bladder 64 is exhausted, the air bladder post 661 collapses and contracts and no longer in a inflated state, that is, the groove 662 can no longer catch the hook ring 654, and then the pull-back member 653 pulls the sliding barrel 652 along the side wall of the fixed post 651, at which time the sliding barrel 652 pushes the through post 655 through the inner wall of the deep groove 31 and limits the grinding wheel sliding along the socket barrel 11.
In general, the improvement of the invention compared with the prior art is that:
1. the grinding wheel is sleeved with the inner hole avoiding groove 4, so that the inner hole of the grinding wheel cannot contact the main fixing sleeve 1 for the first time, and the inner hole of the grinding wheel is prevented from being scratched.
2. When the grinding wheel slides to the inner hole avoiding groove 4 area, the grinding wheel is subjected to primary limiting through the cooperation of the lower pressing block 7 and the jacking column 8.
3. If the primary limiting is not completed, the secondary limiting can be performed through the through stop post 655.
