Refer to Fig. 1 and 2, this blocks the hollow rectangular structure that frame 60 can be opened and close as door 62 for side, this abrasive band 28, this driving wheel 24, this gripper shoe 26 are all housed in this and block in frame 60, and this blocks in frame 60 and arranges flusher, for spraying cooling fluid to this gripper shoe 26.On the other hand, this blocks frame 60 and can prevent the useless splashes of cutting after cutting from hurting people or thing, also can avoid extraneous dust, contaminating impurity workpiece.This blocks frame 60 and is fixed on this antetheca 163, and offers porose to make propelling sheave 349, driving wheel 24 and gripper shoe 26 all can block frame 60 and pass from this above.
Before grinding, first adjust this abrasive band 28 in the distance of first direction (in Fig. 2 Z-direction) above and between this workpiece 200 by this wheel head adjusting mechanism 30, and adjust this abrasive band 28 in the distance of second direction (in Fig. 2 X-direction) above and between this workpiece 200.Particularly, this bistrique regulates motor 322 to drive this bistrique to regulate screw mandrel 324 to rotate, because this bistrique regulates screw mandrel 324 with this loop bar 326 for being threaded, and this loop bar 326 is fixed on the diapire 162 of this moveable arm 16, and the rotation of this moveable arm 16 is limited by this fixed arm 14, thus, this loop bar 326 can only move up and down (moving around along Z-direction) along this guide rail 149, drive this moveable arm 16 to move up and down along this guide rail 149 thus, and then drive the grinding head assembly 20 be fixed on this moveable arm 16 also to move up and down along this guide rail 149.Therefore, drive this grinding head assembly 20 to move back and forth, desirable scope just can be adjusted in the distance of first direction (in Fig. 2 Z-direction) above and between this workpiece 200 in this abrasive band 28.Then, regulate this butterfly screws 346, this adjusting rod 344 drives this installing rack 348 to rotate, to change the pitch angle of this installing rack 348, thus realize abrasive band 28 moving axially (movement of X-direction) along described contact wheel 264, this abrasive band 28 just can be finely tuned in the distance of second direction (in Fig. 2 X-direction) above and between this workpiece 200, thus abrasive band 28 is aimed at workpiece 200.
When above-mentioned adjustment is complete, just can carry out grinding, this bistrique actuator 22 drives this driving wheel 24 to rotate, and this driving wheel 24 drives this abrasive band 28 to move, there is provided back pressure generation to the contact of workpiece 200 by this contact wheel 264 and form grinding angle, completing the grinding to workpiece 200 and polishing.In the process, this hydraulic column 44 drives one end of this adjustable plate 42 to rotate relative to its other end, thus this bistrique actuator 22 be fixed on this adjustable plate 42 is improved, and then this driving wheel 24 coordinated with this bistrique actuator 22 is also elevated, therefore the abrasive band 28 be enclosed within this driving wheel 24 is also tensioned.In grinding and polishing process, the cooling fluid with pressure can be injected from hand-hole 2624, part cooling fluid directly flows to the centre position of this contact wheel 264, another part cooling fluid flows to the two ends of contact wheel 264 successively through this guide hole 2626 and multiple through hole 2627, thus can effectively and cool this contact wheel 264 equably.And, because cooling fluid has pressure, contact wheel 264 after injection, can be made to be suspended in cooling fluid, when abrasive band 28 driven rotary, decrease friction and noise, improve rotating speed.
In addition, the amount of feeding of grinding and polishing can be regulated by this workpiece adjusting part 50.Particularly, this workpiece regulates motor 56 to drive this workpiece to regulate screw mandrel 58 to rotate, because this workpiece regulates screw mandrel 58 with this projection 57 for being threaded, and this projection 57 is fixed on this microscope carrier 54, and the rotation of this microscope carrier 54 is limited by this guide rail platform 52, thus, this projection 57 (the positive negative direction of Y-axis) can only move before and after this guide rail 522, and then drive this microscope carrier 54 to move forward and backward along this guide rail 522, so, just the amount of feeding can be adjusted according to the situation of grinding and polishing.
The abrasive belt grinding machine 100 provided in present embodiment utilizes wheel head adjusting mechanism 30 to adjust the distance of this abrasive band 28 in the first direction and between this workpiece 200, and adjust the distance of this abrasive band 28 in this second direction and between this workpiece 200, thus make this abrasive band 28 can be ground to complex-curved by workpiece 200, and whole process is automatic control, avoid manual operation, so, grinding thickness is even, the quality of profile can not only be ensured, can also machining accuracy be ensured while increasing work efficiency, reduce labor strength.In addition, spray cooling fluid when sbrasive belt grinding by flusher and dirt bits can be avoided to fly upward, ensure that processing saves environment-friendly dustless clearly.
Be appreciated that, in other embodiments, the two ends of this contact wheel 264 offer hole clipping respectively, the two ends of this accepting groove 2620 are respectively arranged with the card column corresponding with this hole clipping, and two card columns are fastened on respectively in two hole clippings and this contact wheel 264 can be installed in this accepting groove 2620 rotationally.Or the two ends of this contact wheel 264 are respectively arranged with card column, the two ends of this accepting groove 2620 are respectively arranged with the hole clipping corresponding with this card column, and two card columns are fastened on respectively in two hole clippings and this contact wheel 264 can be installed in this accepting groove 2620 rotationally.
Above disclosedly be only present pre-ferred embodiments, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the claims in the present invention are done, still belong to the scope that the present invention is contained.
