The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
In order to solve the problem that the grinding wheel is prone to thermal cracking if the inner hole of the grinding wheel is smaller than the diameter of the outer side of the fixing piece and the grinding wheel is forcibly sleeved on the fixing piece.
As shown in fig. 1 to 8, the present invention provides an embodiment of a five-axis numerical control grinding apparatus.
Specifically, the five-axis numerical control grinding equipment structurally comprises a grinding wheel fixing mechanism arranged at the driving end of a 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 tool body 91 and an auxiliary fixing sleeve 2 connected with the main fixing sleeve 1, and the auxiliary fixing sleeve 2 is detachably connected with the driving end of the grinding machine tool body 91;
the main fixing sleeve 1 can penetrate through the inner hole of the grinding wheel and limit the grinding wheel sleeved on the outer side of the main fixing sleeve, 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, close to the auxiliary fixing sleeve 2, of the main fixing sleeve 1, and an inner hole avoiding groove 4 is formed in the side wall, close to the auxiliary fixing sleeve 2, of one end of the main fixing sleeve 1;
hollow plug heads 5 are arranged in all the mounting grooves 3, a return elastic piece 6 is arranged at one end, away from the inner hole avoiding groove 4, of each hollow plug head 5, a lower pressing block 7 is arranged at one end, away from the return elastic piece 6, of each hollow plug head 5, all the lower pressing blocks 7 are arranged in the inner hole avoiding groove 4, a jacking column 8 is 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 an inner hole of the grinding wheel to move towards the axial lead direction of the main fixing sleeve 1 and push the corresponding hollow plug 5 to press the return elastic piece 6, and the jacking column 8 can slide out of the hollow plug 5 when the lower pressing block 7 moves towards the axial lead direction of the main fixing sleeve 1.
In this embodiment, all the lower pressing blocks 7 are annularly arranged as shown in fig. 4, 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 move easily without external force.
Meanwhile, in this embodiment, the return elastic member 6 can respectively provide supporting force for the hollow plug 5 and the jacking column 8, so that when the hollow plug 5 is pressed, the jacking column 8 is not pressed, but is supported and kept at the initial position by the supporting force provided by the return elastic member 6.
The invention can limit the action of a grinding wheel with a smaller inner hole diameter through the matching of a plurality of lower pressing blocks 7 and a plurality of jacking columns 8, when in specific implementation, the main fixing sleeve 1 is directly inserted into the inner hole of the grinding wheel, then, because of the existence of the inner hole avoiding groove 4, the inner wall of the inner hole of the grinding wheel can not directly contact with the side wall of the main fixing sleeve 1 but contact 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 can be 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 can 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 as to limit the grinding wheel, and prevent the grinding wheel from sliding through the inner hole avoiding groove 4 and being 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 groove 4 can be avoided through the inner hole, the inner hole of the grinding wheel cannot be directly contacted with the outer side wall of the main fixing sleeve 1 (namely, the inner wall of the inner hole of the grinding wheel is avoided) when being arranged outside the main fixing sleeve 1 in a penetrating way, but because the inner hole avoiding groove 4 is internally provided with the lower pressing block 7, the phenomenon that the end part of the lower pressing block 7 is propped against the edge of the inner hole of the grinding wheel still can occur in the process of the grinding wheel penetrating way, so that the main fixing sleeve 1 preferably comprises a sleeve connecting cylinder 11 and a fixed disc 12 which are sequentially arranged along the direction of the grinding wheel inner hole penetrating way, and the inner hole avoiding groove 4 is arranged on the side wall of one end of the sleeve connecting cylinder 11, which is far away from the fixed disc 12;
one end of the lower pressing block 7, which is far away from the main fixing sleeve 1, is provided with a guiding 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 needs to penetrate through the outer side of the main fixing sleeve 1, the grinding wheel inner hole can be directly guided to be close to one end, away from the fixed disk 12, of the sleeve joint cylinder 11, at the moment, the inner hole avoiding groove 4 is formed in one end side wall, away from the fixed disk 12, of the sleeve joint cylinder 11, the grinding wheel inner hole cannot be directly contacted with the end side wall of the sleeve joint cylinder 11 and is contacted with all the lower pressing blocks 7, when the grinding wheel inner hole is contacted with all the lower pressing blocks 7, due to the existence of the guide-in cambered surface 13, the lower pressing block 7 cannot abut against the grinding wheel inner hole edge and obstruct the penetration of the grinding wheel, the specific operation flow is that (the lower pressing block 7 is exemplified here), when the grinding wheel inner hole edge contacts the lower pressing block 7, the grinding wheel inner hole edge slides along the guide-in cambered surface 13 and gradually applies downward pressing force to the lower pressing block 7, and the lower pressing block 7 moves towards the axial lead direction of the main fixing sleeve 1 (the specific movement direction of the lower pressing block 7 is perpendicular to the axial lead direction of the main fixing sleeve 1).
In order to provide the supporting force for the hollow plug 5 and the jacking column 8, respectively, it is preferable that the return spring 6 comprises a mounting cover 61 connected in the mounting groove 3, a supporting air bag 62 is arranged in the mounting cover 61, a packing block 63 fixedly connected with the hollow plug 5 is arranged on the surface of the supporting air bag 62, and a pushing-out bag 64 fixedly connected with the end of the jacking column 8 is arranged in the supporting air bag 62.
In this embodiment, the supporting air bag 62 and the pushing-out bag 64 are both filled with air, and the packing block 63 is provided with a clamping groove at a position corresponding to the pushing-out bag 64 as shown in fig. 8, referring to fig. 7, so that the pushing-out bag 64 has a certain movement space and cannot move along with the supporting air bag 62.
Can realize among the prior art respectively to the 6 kinds of return elastic component that provide holding power to cavity chock plug 5 and jack-up post 8, for example directly set up the elastic component of ring cover formula can (for example set up two covers and establish the spring together, inboard spring is connected with jack-up post 8, the outside is connected with cavity chock plug 5), but the phenomenon of briquetting 7 slope down appears easily like this, lead to the downthehole briquetting 7 that pushes down of emery wheel can't fully laminate with emery wheel hole inner wall, and the return elastic component 6 that provides in this embodiment, can ensure briquetting 7 down and emery wheel hole inner wall laminating always.
When the lower pressing block 7 moves towards the axial lead direction of the main fixing sleeve 1, the hollow plug 5 corresponding to the lower pressing block 7 is pushed, so that the packing block 63 is pushed to slide along the inner wall of the mounting cover 61 and compress the supporting air bag 62, so that the supporting air bag 62 moves towards the bottom of the mounting cover 61, but the push-out bag 64 is not compressed integrally but compressed except for other parts corresponding to the clamping groove (taking fig. 7 as an example, the top edge of the push-out bag 64 is pressed, so that the top of the push-out bag 64 is bulged, and other parts are compressed).
That is, when the lower pressing block 7 moves toward the axial line direction of the main fixing sleeve 1, the jacking post 8 supported by the pushing out bag 64 gradually extends out of the hollow plug 5 (the reason why the jacking post 8 gradually extends out of the hollow plug 5 is that the top of the pushing out bag 64 is bulged at this time, and the height of the supporting air bag 62 is gradually reduced, so that the jacking post 8 is pushed by the bulged jacking out bag 64, and the jacking post 8 is led to extend out of the hollow plug 5), so as to limit the grinding wheel.
Sometimes, the difference between the difference value between the inner diameter of the inner hole of the grinding wheel and the outer diameter of the sleeve 11 is not large (that is, the inner diameter of the inner hole of the grinding wheel is smaller than the outer diameter of the sleeve 11 but not enough for the jacking column 8 to extend out of the hollow plug 5 to limit the grinding wheel), that is, the inner hole of the grinding wheel pushes the lower pressing block 7 to descend to a smaller diameter, which cannot meet the purpose of limiting the grinding wheel, so preferably, the surface of the lower pressing block 7 and the corresponding position of the hollow plug 5 are provided with an air guide groove 71, the inner side wall of the air guide groove 71 is provided with an air release groove 72, a pressing sheet 73 fixedly connected with the jacking column 8 is arranged in the air guide groove 71, and the air in the jacking column 8 and the inner side wall of the hollow plug 5 can guide the pushing bag 64 to discharge air;
the end of the ejection column 8 remote from the pressing plate 73 is provided with a puncturing head 74 capable of puncturing the ejection capsule 64.
When the difference numerical value between emery wheel hole internal diameter and the 11 outside diameters of cup joint section of thick bamboo differed not much (the condition at this moment is, emery wheel hole internal diameter is less than 11 outside diameters of cup joint section of thick bamboo, but be not enough to make jack-up post 8 stretch out cavity chock 5 and carry on spacingly to the emery wheel), in case emery wheel hole inner wall slides and is close jack-up post 8 along briquetting 7 down, emery wheel hole inner wall can be earlier with preforming 73 contact, and with preforming 73 impress air guide groove 71 (this is because, emery wheel hole internal diameter is less than 11 outside diameters, when emery wheel hole inner wall contact preforming 73, also can push away preforming 73 activity).
Then, the pressing piece 73 entering the air guide groove 71 pushes the jack-up post 8 to press the push-out bag 64, and when the jack-up post 8 presses the push-out bag 64, the puncturing head 74 punctures the push-out bag 64, so that the air in the push-out bag 64 is exhausted, and then the exhausted air enters the air guide groove 71 along the gap between the jack-up post 8 and the inner side wall of the hollow plug 5 and is exhausted along the air exhaust 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 easily clamped on the side wall of the sleeve 11 once the grinding wheel is too forcefully violent, so that an operator mistakenly thinks that no problem exists in matching, and in order to avoid the phenomenon, preferably, the inner side wall of the mounting groove 3 is provided with a deep groove 31;
the side wall of the push-out bag 64 is provided with an extension segment 641 which penetrates through the mounting cover 61 and extends to the deep groove 31, the surface of the extension segment 641 is provided with a protrusion column 642, the protrusion column 642 can penetrate through the inner wall of the deep groove 31 and limit the grinding wheel sliding along the sleeve joint barrel 11, the surface of the extension segment 641 is provided with a plurality of blocking columns 643 which are communicated with the extension segment 641, and the blocking columns 643 are used for exerting pulling force on the protrusion column 642.
In this embodiment, the inner wall of the deep groove 31 is provided with a through hole corresponding to the protruding column 642 for guiding the protruding column 642 to protrude.
Once the gas in the push-out bladder 64 is exhausted, the blocking post 643 is no longer in the expanded state (because the blocking post 643 is connected to the push-out bladder 64 through the extension 641), that is, the pulling force applied to the protruding post 642 is reduced, so that the protruding post 642 can pass through the inner wall of the deep groove 31 and limit the grinding wheel sliding along the socket 11.
Further optimization for the protruding column 642: the extending column 642 comprises a fixing column 651 mounted on the surface of the extending section 641, a sliding cylinder 652 is sleeved on the outer side of the fixing column 651, a pull-back piece 653 connected with the sliding cylinder 652 is fixedly sleeved on the side wall of the fixing column 651, a hook ring 654 is mounted at one end of the sliding cylinder 652 close to the extending section 641, the hook ring 654 can be hooked by a blocking column 643, and a through blocking column 655 is connected at one end of the sliding cylinder 652 far from the extending section 641.
Further optimization for the barrier column 643: the blocking post 643 includes a bladder post 661 in communication with the extension 641, the bladder post 661 defines a groove 662 that mates with the hook 654, and gas within the bladder post 661 can enter the push-out bladder 64 along the extension 641.
In this embodiment, the pull back 653 may be a tension spring.
When the gas in the push-out bag 64 is exhausted, the air bag post 661 will collapse and contract and will not be in the inflated state, that is, the groove 662 can not block the hook ring 654 any more, then the pull-back piece 653 will pull the sliding cylinder 652 to slide along the side wall of the fixed post 651, at this time, the sliding cylinder 652 will push the through stop post 655 to pass through the inner wall of the deep groove 31 and limit the grinding wheel sliding along the socket 11.
The side wall of the push-out pocket 64 is provided with an expansion groove 671, and an end of the push-out pocket 64 near the jack-up post 8 is provided with a sheet 672. The expansion groove 671 is provided so that when the push-out bag 64 is compressed, the gas inside the push-out bag 64 expands along the expansion groove 671, and when the push-out bag 64 is compressed, the gas inside the push-out bag 64 also expands the push-out bag 64, specifically, the sheet 672 is raised, and thereafter the raised sheet 672 is raised against the knock-up post 8.
When the emery wheel during operation, in order to make the hole dodge groove 4 can not exert an influence to the emery wheel of cup jointing at the 11 lateral walls of socket joint (the hole dodges the existence of groove 4 and can produce the space, leads to the emery wheel to appear rocking phenomenon easily), so preferred, vice fixed cover 2 includes can dismantle fixed connection's expansion disc 21 with grinding lathe body 91 drive end, one side surface that expansion disc 21 is close to socket joint 11 is equipped with and dodges groove 4 assorted cooperation ring piece 22 with the hole.
After the grinding wheel is sleeved on the sleeve joint barrel 11, the matching ring piece 22 is inserted into the inner hole to avoid the groove 4, and then the movable disc 21 and the driving end of the grinding machine tool body 91 are detachably and fixedly connected through the bolt.
The five-axis numerical control grinding equipment further comprises a base 9, wherein a grinding machine tool body 91 is mounted on the base 9, and a 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 tool body 91 is connected to the grinding wheel fixing mechanism, and when the grinding machine tool works, the driving end of the grinding machine tool 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 the grinding wheel is used, the main fixing sleeve 1 is directly inserted into the grinding wheel inner hole (in actual operation, the main fixing sleeve 1 is firstly sleeved on the driving end of the grinding machine tool body 91, then the main fixing sleeve 1 is sleeved with the grinding wheel inner hole, and relatively speaking, the main fixing sleeve 1 is inserted into the grinding wheel inner hole).
Specifically speaking, direct guide emery wheel hole is close to the one end that fixed disk 12 was kept away from to cup joint section of thick bamboo 11, because the hole dodges groove 4 and sets up the one end lateral wall of keeping away from fixed disk 12 at cup joint section of thick bamboo 11 this moment, so the emery wheel hole can not be direct with the contact of cup joint section of thick bamboo 11 tip lateral wall, but with the contact of all briquetting 7 down, and when the emery wheel hole contacted with all briquetting 7 down, because the existence of leading-in cambered surface 13, briquetting 7 can not support emery wheel hole edge and hinder wearing to establish production of emery wheel down.
The specific operation flow is (illustrated here by a hold-down 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 down the lower pressing block 7 along the guide-in cambered surface 13, so that the lower pressing block 7 moves towards the axial lead direction of the main fixing sleeve 1.
When the lower pressing block 7 moves towards the axial lead direction of the main fixing sleeve 1, the hollow plug 5 corresponding to the lower pressing block 7 is pushed, so that the packing block 63 is pushed to slide along the inner wall of the mounting cover 61 and compress the supporting air bag 62, so that the supporting air bag 62 moves towards the bottom of the mounting cover 61, but the pushing-out bag 64 is not compressed integrally but is compressed except for other parts corresponding to the clamping groove. That is, when the lower pressing block 7 moves towards the axial lead direction of the main fixing sleeve 1, the top of the pushing-out bag 64 expands and jacks up the jacking column 8 in the hollow plug 5, so that the jacking column 8 gradually extends out of the hollow plug 5 to limit the grinding wheel.
When the difference value between the inner diameter of the inner hole of the grinding wheel and the outer diameter of the sleeve joint barrel 11 is not large (the inner diameter of the inner hole of the grinding wheel is smaller than the outer diameter of the sleeve joint barrel 11 but is not enough to enable the jacking column 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 is close to the jacking column 8, the inner wall of the inner hole of the grinding wheel can be firstly contacted with the pressing sheet 73, and the pressing sheet 73 is pressed into the air guide groove 71.
Then, the pressing piece 73 entering the air guide groove 71 pushes the jack-up post 8 to press the push-out bag 64, and when the jack-up post 8 presses the push-out bag 64, the puncturing head 74 punctures the push-out bag 64, so that the air in the push-out bag 64 is exhausted, and then the exhausted air enters the air guide groove 71 along the gap between the jack-up post 8 and the inner side wall of the hollow plug 5 and is exhausted along the air exhaust groove 72.
Once the gas in the push-out bag 64 is exhausted, the blocking post 643 will no longer be in the expanded state (because the blocking post 643 is connected to the push-out bag 64 through the extension 641), that is, when the gas in the push-out bag 64 is exhausted, the air bag post 661 will collapse and shrink and will no longer be in the inflated state, that is, the groove 662 can no longer catch the hook ring 654, and then the pull-back member 653 will pull the sliding cylinder 652 to slide along the sidewall of the fixed cylinder 651, at which time the sliding cylinder 652 will push through the blocking post 655 and pass through the inner wall of the deep groove 31 and limit the grinding wheel sliding along the sleeve 11.
In general, the improvement of the present invention over the prior art is:
1. the accessible hole dodges groove 4 and dodges when the emery wheel cup joints to make the emery wheel hole can not contact main fixed cover 1 in the first time, take place in order to prevent the condition that the emery wheel hole was scraped badly.
2. When the grinding wheel slides to the inner hole to avoid the area of the groove 4, the grinding wheel is limited for the first time through the matching of the lower pressing block 7 and the jacking column 8.
3. If the primary restraint is not done for the purpose of restraint, a secondary restraint may be performed by passing through the stop column 655.
