[0002] A grinding machine is a forming machine that uses a grinding wheel to perform precision machining on the surface of a workpiece. It is mainly used to improve the dimensional accuracy, shape accuracy and surface finish of the workpiece.

[0049] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] In order to reduce the labor intensity of replacing the grinding wheel 5 and improve the efficiency of replacing the grinding wheel 5, the present application provides a grinding machine tool, such as Figure 1 and Figure 2 As shown, the grinding machine tool includes a bed, a gantry, a workbench, a grinding mechanism and a grinding wheel replacement device, and the grinding wheel replacement device is used to replace the grinding wheel installed on the grinding mechanism. The grinding wheel replacement device includes a grinding wheel replacement device, wherein the grinding wheel replacement device includes a base 1, a motion mechanism 2 and a support mechanism 3.

[0051] The base 1 can be fixed on the ground on both sides of the frame of the grinding machine, or the base 1 can also be fixed on the frame of the grinding machine. The base 1 is used to support the motion mechanism 2 and the support mechanism 3. The base 1 can be made of metal or any other material. The material, size and shape of the base 1 are not specifically limited in this application, as long as it can support the motion mechanism 2 and the support mechanism 3.

[0052] The supporting mechanism 3 includes a fixing unit and a driving unit. The fixing unit is mounted on the moving mechanism 2, and the driving unit can be mounted on the moving mechanism or on other components. The fixing unit can absorb or clamp the grinding wheel chuck 4 or the grinding wheel 5, that is, the grinding wheel 5 or the grinding wheel chuck 4 is positioned by the fixing unit. The driving unit can drive the fixing unit to release or fix the grinding wheel chuck 4 or the grinding wheel 5.

[0053] The motion mechanism 2 is mounted on the base 1, and the motion mechanism 2 can drive the fixed unit to rotate and / or move relative to the base 1, so as to drive the fixed unit to move to the target position. Specifically, the motion mechanism 2 can only drive the fixed unit to rotate, or only drive the fixed unit to move; the motion mechanism 2 can also drive the fixed unit to rotate and move. Finally, the motion mechanism 2 drives the fixed unit and the grinding wheel 5 or the grinding wheel chuck 4 thereon to move to the target position. The target position can refer to the bottom of the grinding wheel 5 of the grinding machine or one side of the grinding wheel 5, so as to facilitate the replacement of the grinding wheel 5. It can be understood that when the fixed unit of the support mechanism 3 adsorbs or clamps the grinding wheel chuck 4, the grinding wheel 5 can be fixed on the grinding wheel chuck 4, and the motion mechanism 2 drives the fixed unit, the grinding wheel chuck 4 and the grinding wheel 5 to move together; when the fixed unit of the support mechanism 3 adsorbs or clamps the chuck, the motion mechanism 2 drives the fixed unit and the grinding wheel 5 to move together. In other words, when the fixing unit of the supporting mechanism 3 adsorbs or clamps the grinding wheel chuck 4, the process of replacing the grinding wheel 5 is replaced together with the grinding wheel chuck 4. The following description will be made by taking the fixing unit of the supporting mechanism 3 adsorbing or clamping the grinding wheel chuck 4 as an example.

[0054] In the process of replacing the grinding wheel 5 of the grinding machine provided by the present application, the motion mechanism 2 drives the fixed unit to rotate and / or move, so that after the fixed unit moves to the target position, the grinding wheel fixing component of the grinding machine releases the grinding wheel chuck 4, and the fixed unit absorbs or clamps the grinding wheel chuck 4, so that the grinding wheel chuck 4 with the grinding wheel 5 installed is transferred to the fixing unit. Then, the driving unit drives the fixing unit to fix the grinding wheel chuck 4 with the new grinding wheel 5 installed, the motion mechanism 2 drives the fixed unit to rotate and / or move, so that the fixed unit moves to the target position, and then the driving unit drives the fixing unit to release the grinding wheel chuck 4 with the new grinding wheel 5 installed, and the grinding wheel fixing component of the grinding machine fixes the grinding wheel chuck 4 with the new grinding wheel 5 installed, so as to transfer the grinding wheel chuck 4 with the new grinding wheel 5 installed to the grinding wheel 5 installation position of the grinding machine, and finally realize the replacement of the grinding wheel 5.

[0055] From the above, it can be seen that when the grinding wheel 5 is replaced by the grinding machine provided in the present application, the motion mechanism 2 only needs to drive the fixed unit to rotate and / or move, and then the driving unit controls the fixed unit to release or fix the grinding wheel chuck 4. There is no need for manual participation in the disassembly, installation, transfer and other processes of the grinding wheel chuck 4, which reduces the labor intensity. At the same time, the replacement process consumes less time, which improves the efficiency of grinding wheel replacement, reduces the downtime of the grinding machine, and thus improves the production efficiency of the grinding machine.

[0056] It can be understood that the position where the grinding wheel chuck 4 is used to cooperate with the grinding wheel fixing part of the grinding machine is different from the position where the grinding wheel chuck 4 is used to cooperate with the fixing unit. Specifically, after the suspension rod of the grinding machine is extended into the interior of the grinding wheel chuck 4, the suspension rod supports the inner wall of the grinding wheel chuck 4 and fixes the grinding wheel chuck 4. Thus, it can be achieved that the fixing unit releases or fixes the grinding wheel chuck 4 and the grinding wheel fixing part of the grinding machine releases or fixes the grinding wheel chuck 4 simultaneously without affecting each other.

[0057] In addition, if Figure 3 As shown, the grinding wheel chuck 4 includes a chuck body 42 and a pressure plate 40, and the pressure plate 40 is detachably connected to the chuck body 42, and the detachable connection can be achieved by bolts. After the chuck body 42 and the pressure plate 40 are fixedly connected, a clamping groove 41 is formed between the chuck body 42 and the pressure plate 40, and the grinding wheel 5 can be installed in the clamping groove 41, so that the grinding wheel chuck 4 and the grinding wheel 5 can be assembled together.

[0058] In some embodiments, Figure 1-2 As shown in 4-5, the motion mechanism 2 may include a rotating plate 20, and the rotating plate 20 can rotate relative to the base 1 around a first axial direction, and the first axial direction can be a vertical direction. The fixed unit is arranged on the rotating plate 20, and the axis of the grinding wheel 5 mounted on the grinding wheel chuck 4 on the fixed unit can be along the vertical direction, so as to facilitate the replacement of the grinding wheel 5 whose axis is along the vertical direction on the grinding machine. In the process of replacing the grinding wheel 5, the rotating plate 20 rotates around the first axial direction, thereby driving the fixed unit to rotate, so that the fixed unit rotates to the target position or away from the target position. It should be noted that in this technical solution, the fixed unit needs to be set away from the rotation axis of the rotating plate 20 to ensure that the fixed unit can rotate to the target position during the rotation of the rotating plate 20. With this technical solution, it is only necessary to rotate the rotating plate 20, which is simple to operate, and the structure is simple and easy to process.

[0059] In some embodiments, the number of the fixing units may be multiple, for example, two, three or more. The multiple fixing units are circumferentially dispersedly installed on the rotating plate 20, that is, the multiple fixing units can be evenly distributed circumferentially around the rotation axis of the rotating plate 20. With this technical solution, a fixing unit can be rotated to the target position to receive the old grinding wheel 5 and its grinding wheel chuck 4 that need to be replaced on the grinding machine, and then during the rotation of the rotating plate 20, the grinding wheel chuck 4 with the new grinding wheel 5 fixed on another fixing unit is rotated to the target position, so as to facilitate the grinding wheel fixing part of the grinding machine to quickly install the grinding wheel chuck 4 with the new grinding wheel 5. Multiple fixing units can be used alternately, which further improves the efficiency of replacing the grinding wheel 5.

[0060] Preferably, the number of the fixing units is two, and the two fixing units can be used alternately to quickly receive the old grinding wheel chuck 4 and install the new grinding wheel chuck 4.

[0061] In some embodiments, Figure 4 As shown, the motion mechanism 2 further includes a drawer 23 slidably disposed on the base 1, and the rotating plate 20 is rotatably disposed on the drawer 23. Specifically, a slide rail may be disposed on the base 1, and the drawer 23 slidably cooperates with the slide rail. The drawer 23 slides along the slide rail while driving the rotating plate 20 to slide together. The drawer 23 may slide along the slide rail in a horizontal direction to approach the grinding wheel 5 of the grinding machine or to move away from the grinding wheel 5 of the grinding machine. With this technical solution, when the grinding wheel 5 needs to be replaced, as shown in FIG. Figure 8 As shown, the pull-out member 23 can be used to first drive the rotating plate 20 and the fixed unit to slide close to the target position, and then the rotating plate 20 drives the fixed unit to rotate to the target position; the setting of the pull-out member 23 can appropriately reduce the size of the rotating plate 20, thereby helping to reduce the volume of the grinding machine and reduce the installation space of the grinding machine.

[0062] The drawer 23 may be a drawer plate or a drawer frame, etc. It is understood that when the motion mechanism 2 does not include the drawer 23, the rotating plate 20 can be directly rotatably disposed on the base 1. Specifically, the rotating plate 20 can be rotatably disposed on the drawer 23 or the base 1 through components such as bearings.

[0063] In some embodiments, Figure 6 and Figure 7 As shown, the motion mechanism 2 further includes at least one group of guide rollers 22 disposed on the drawer 23, and a track groove 21 is disposed at the bottom of the rotating plate 20, and the guide rollers 22 can extend into the track groove 21. Specifically, during the rotation of the rotating plate 20 around the first axial direction, when the track groove 21 at the bottom of the rotating plate 20 rotates to the position of the guide rollers 22, the guide rollers 22 extend into the track groove 21, and the guide rollers 22 rotate along the track groove 21, so as to support the rotating plate 20 with the guide rollers 22, and at the same time, the guide rollers 22 can prevent the rotating plate 20 from deflecting.

[0064] The bottom of the rotating plate 20 may be provided with one, two or more track grooves 21 to improve the stability of the rotation of the rotating plate 20. Multiple groups of guide rollers 22 may also be provided, and multiple groups of guide rollers 22 simultaneously support the rotating plate 20, which can further prevent the rotating plate 20 from deflecting during the rotation process.

[0065] In the structure of a grinding machine, it may be necessary to simultaneously set a grinding wheel 5 that rotates around a horizontal axis and a grinding wheel 5 that rotates around a vertical axis to process the top or bottom surface and the side surface of the workpiece respectively. When replacing the grinding wheel 5 that rotates around a vertical axis, the grinding wheel fixing component of the grinding machine needs to press down the fixing unit during the alignment process with the grinding wheel chuck 4 on the fixing unit to ensure accurate alignment with the grinding wheel chuck 4, so the fixing unit and the rotating plate 20 need to withstand the downward pressure of the grinding wheel fixing component of the grinding machine. In view of the above situation, in the present technical solution, each group of guide rollers 22 includes a support fixed on the pull-out member 23, a first guide roller and a second guide roller rotatably arranged on the support, and the rolling axis of the first guide roller and the second guide roller can be perpendicular to the rotation axis of the rotating plate 20, that is, when the rotating plate 20 rotates around the vertical axis, the first guide roller and the second guide roller roll around the horizontal axis. Along the rotation axis of the rotating plate 20, the top of the first guide roller can contact the top wall of the track groove 21, and the bottom of the second guide roller can contact the bottom wall of the track groove 21. In other words, the first guide roller and the second guide roller of the same group can be staggered along the rotation axis of the rotating plate 20, that is, when the rotating plate 20 rotates around the vertical axis, the top of the first guide roller and the top of the second guide roller of the same group have a height difference. With this arrangement, the top of the first guide roller can contact the top wall of the track groove 21, and the bottom of the second guide roller can contact the bottom wall of the track groove 21, so as to ensure that during the downward pressing process, the rotating plate 20 is supported by the first guide roller and does not tilt.

[0066] Furthermore, when the first guide roller and the second guide roller have the same size, the axis of the first guide roller and the axis of the second guide roller have a height difference along the rotation axis (vertical direction) of the rotating plate 20. Of course, when the first guide roller and the second guide roller have different sizes, the top of the first guide roller is higher than the top of the second guide roller, and the bottom of the first guide roller is higher than the bottom of the second guide roller. The guide roller 22 can be specifically a roller.

[0067] In some embodiments, Figure 5 As shown, the base 1 is provided with an anti-slip member 10 and / or an elastic buffer 11, and the drawer 23 can slide until it contacts the anti-slip member 10 and / or the elastic buffer 11. Specifically, after the drawer 23 slides a certain distance, the anti-slip member 10 and / or the elastic buffer 11 can resist the drawer 23 from continuing to slide, thereby preventing the drawer 23 from detaching from the base 1. Among them, the elastic buffer 11 has a buffering effect to prevent the drawer 23 from being damaged by collision. The elastic buffer 11 can directly adopt the elastic buffer 11 that is more common on the market, and its structure is not specifically limited in this application.

[0068] In some embodiments, Figure 5As shown, the motion mechanism 2 also includes a first locking assembly, and the function of the first locking assembly is to lock the drawer 23 when the grinding wheel 5 does not need to be replaced to prevent the drawer 23 from sliding. The first locking assembly includes a pull rod 24 and a stop block hinged to the end of the pull rod 24. The bottom of the drawer 23 has a stop boss. The pull rod 24 is pulled to drive the stop block to rotate to abut against the stop boss or avoid the stop boss. Specifically, the stop block can be hinged to the pull rod 24, and the stop block can be L-shaped. In the process of pulling the pull rod 24, the L-shaped stop block rotates to avoid the stop boss, and the drawer 23 can slide freely at this time; in the process of pushing the pull rod 24 in the opposite direction, the L-shaped stop block abuts against the stop boss, and the drawer 23 is blocked by the stop block and cannot slide, thereby preventing the slide of the drawer 23 from affecting the operation of the grinding machine during the normal operation of the grinding machine.

[0069] In some embodiments, Figure 6 As shown, the motion mechanism 2 further includes a second locking assembly 26, which can be inserted into the positioning groove of the rotating plate 20 to prevent the rotating plate 20 from rotating. The function of the second locking assembly 26 is to lock the rotating plate 20 to prevent the rotating plate 20 from rotating when the grinding wheel 5 does not need to be replaced. Specifically, the second locking assembly 26 can be inserted into the positioning groove of the rotating plate 20, and the second locking assembly 26 blocks the movement of the inner wall of the positioning groove, thereby limiting the rotation of the rotating plate 20. When the grinding wheel 5 needs to be replaced, the second locking assembly 26 only needs to be pulled out from the positioning groove of the rotating plate 20.

[0070] In some embodiments, Figure 5 As shown, the drawer 23 is also provided with a groove and / or a handle 27, and the rotating plate 20 is also provided with a groove and / or a handle 27, so that the operator can rotate the rotating plate 20 and pull the drawer 23. Of course, the rotating plate 20 can also be driven by a motor to rotate, and a telescopic component (such as an oil cylinder, an air cylinder, etc.) can be used to drive the drawer 23 to slide. During the rotation process of the rotating plate 20, different positions may be close to the operator, so a plurality of grooves and / or handles 27 can be provided on the rotating plate 20, for example, four, three, etc. grooves and / or handles 27 are provided.

[0071] Furthermore, a limiter is provided on the lower side of the groove and / or the handle 27, so that the operator's hand is blocked when it reaches the limiter, which can prevent the operator's hand from being bumped or cut by extending too deep. The limiter can be specifically a limit plate.

[0072] In some embodiments, a position sensor 25 can also be provided on the pull-out member 23. The position sensor 25 is used to detect whether the rotating plate 20 drives the fixed unit to rotate to a set position. If the position sensor 25 detects that the rotating plate 20 drives the fixed unit to rotate to a set position, the fixed unit can be controlled to release the grinding wheel chuck 4. At the same time, the grinding wheel fixing component of the grinding machine fixes the grinding wheel chuck to facilitate the transfer of the grinding wheel chuck 4.

[0073] In some embodiments, the grinding wheel replacement device of the grinding machine may further include a drag chain 28, and some pipes, cables and other components may be placed in the drag chain 28 to prevent the pipes and cables from being damaged due to friction, pulling or twisting.

[0074] In other embodiments, Fig.11 As shown, the motion mechanism 2 may include a first rotating member 20', the first end of the first rotating member 20' is rotatably mounted on the base 1, and the first rotating member 20' can rotate relative to the base 1 around a second axis, and the second axis can be a vertical direction. The first rotating member 20' can drive the support mechanism 3 to rotate, and the support mechanism 3 is rotatably arranged on the motion mechanism 2, and the support mechanism 3 can rotate relative to the motion mechanism 2 around a second axis. In this technical solution, the axis of the grinding wheel 5 mounted on the grinding wheel chuck 4 on the fixed unit can be in a horizontal direction, so as to facilitate the replacement of the grinding wheel 5 on the grinding machine with an axis in a horizontal direction. With this technical solution, when the grinding wheel 5 needs to be replaced, the first rotating member 20' is first used to drive the support mechanism 3 to rotate to the vicinity of the target position, and then the support mechanism 3 is rotated relative to the first rotating member 20' until the grinding wheel chuck 4 on the fixed unit is the same as the axis of the grinding wheel 5 on the grinding machine, so as to facilitate the rapid replacement of the grinding wheel 5.

[0075] Specifically, a shaft sleeve may be provided on the base 1 , and a first end of the first rotating member 20 ′ is fixedly connected to the shaft sleeve, and the shaft sleeve and the first rotating member 20 ′ rotate together relative to the base 1 .

[0076] In some embodiments, Fig.11 As shown, the motion mechanism 2 also includes a second rotating member 21', a first end of the second rotating member 21' is rotatably connected to the second end of the first rotating member 20', and the second rotating member 21' can rotate around the second axial direction relative to the first rotating member 20', and the support mechanism 3 is rotatably connected to the second end of the second rotating member 21'. With this technical solution, the second rotating member 21' can be rotated to a direction away from the base 1, and the first rotating member 20' and the second rotating member 21' are arranged in sequence so that the support mechanism 3 is rotated to the vicinity of the target position. When there is no need to replace the grinding wheel 5, the second rotating member 21' can be rotated to be stacked with the first rotating member 20' or the second rotating member 21' can be rotated to the upper side of the first rotating member 20' (such as Fig.11 As shown) or the lower side, such an arrangement can appropriately reduce the length of the first rotating member 20', thereby reducing the volume and installation space of the grinding machine.

[0077] Among them, along the axial direction of the rotating shaft between the first rotating member 20' and the second rotating member 21', the first rotating member 20' and the second rotating member 21' are staggered. In other words, when the second axial direction is along the vertical direction, the first rotating member 20' and the second rotating member 21' are staggered along the vertical direction, and the second rotating member 21' can be located on the upper side or the lower side of the first rotating member 20', so as to reduce the volume and installation space of the grinding machine.

[0078] The second end of the first rotating member 20' and the first end of the second rotating member 21' may be provided with a bushing, and the rotating shaft passes through the bushing at the second end of the first rotating member 20' and the bushing at the first end of the second rotating member 21', thereby realizing the rotational connection between the first rotating member 20' and the second rotating member 21'.

[0079] like Fig.12 As shown, a mounting hole may be provided at the second end of the second rotating member 21 ′, and the fixing unit may be rotatably mounted in the mounting hole.

[0080] In order to prevent the first rotating member 20' from rotating arbitrarily after the fixing unit moves to the target position or when the grinding wheel 5 does not need to be replaced, the movement mechanism 2 further includes a third locking assembly 22', which can prevent the first rotating member 20' from rotating relative to the base 1. Fig.13 As shown, the third locking assembly 22' may include a pin rod that cooperates with the rotating shaft. After the pin rod is inserted into the positioning groove of the rotating shaft, it prevents the first rotating member 20' from rotating around the rotating shaft. When the first rotating member 20' needs to rotate, the pin rod can be pulled out. Of course, the third locking assembly 22' can also be a tension sleeve, which is not limited here.

[0081] In order to prevent the second rotating member 21' from rotating arbitrarily after the fixed unit moves to the target position or when the grinding wheel 5 does not need to be replaced, the motion mechanism 2 also includes a fourth locking assembly 23', which can prevent the second rotating member 21' from rotating relative to the first rotating member 20'. The structure and principle of the fourth locking assembly 23' are the same as those of the third locking assembly 22'. For details, please refer to the description of the third locking assembly 22' above, which will not be repeated here. Of course, the third locking assembly 22' can also be a tension sleeve, which is not limited here.

[0082] In order to prevent the fixing unit from rotating arbitrarily after the fixing unit moves to the target position or when the grinding wheel 5 does not need to be replaced, as shown in FIG. Fig.11 As shown, the movement mechanism 2 further includes a fifth locking assembly 24', which can prevent the fixed unit from rotating relative to the second rotating member 21'. Fig.14As shown, the fifth locking assembly 24' includes an insert rod 241' and a push rod 242', and the insert rod 241' and the push rod 242' can be hinged, and the push rod 242' is pushed, and then the push rod 242' drives the insert rod 241' to be inserted into the positioning groove of the fixed unit, so that the insert rod 241' prevents the fixed unit from rotating arbitrarily. Of course, the fifth locking assembly 24' can also be a tension sleeve, which is not limited here.

[0083] In some embodiments, Fig. 9 and Fig.10 As shown, the fixing unit includes a housing, at least two claws 34 hinged to the housing, a reset spring 33, and a claw driving member 32. Specifically, each claw 34 is provided with a corresponding reset spring 33, and the reset spring 33 can push the claw 34 to rotate until the end of the claw 34 extends into the pressure groove of the grinding wheel chuck 4. Fig. 9 As shown, the reset spring 33 can push the bottom end of the claw 34, and the top end of the claw 34 has a pressure head, so that the top end of the claw 34 rotates until the pressure head extends into the pressure groove of the grinding wheel chuck 4, pressing the grinding wheel chuck 4, thereby achieving the purpose of clamping and fixing the grinding wheel chuck 4. The claw driving member 32 has an inclined surface that matches the outer wall of the claw 34. The claw driving member 32 rises and its inclined surface pushes the claw 34 to rotate until the end of the claw 34 is separated from the pressure groove of the grinding wheel chuck 4. Specifically, when it is necessary to release the grinding wheel chuck 4, the claw driving member 32 is driven to rise, and the inclined surface of the claw driving member 32 pushes the lower end of the claw 34 in the opposite direction during the rising process, so that the claw 34 compresses the reset spring 33, and at the same time, the top end of the claw 34 rotates to the pressure groove that is separated from the grinding wheel chuck 4. At this time, the fixed component of the grinding machine can fix the grinding wheel chuck 4 and drive the grinding wheel chuck 4 to leave the fixed unit.

[0084] The driving unit includes a lifting driving member 31, and the lifting driving member 31 is retracted to drive the claw driving member 32 to rise and fall. Specifically, the lifting driving member 31 can be a cylinder, an oil cylinder, a linear motor or other components.

[0085] Of course, the fixing unit may also include a plurality of suction cups, and the plurality of suction cups adsorbing the grinding wheel chuck 4 or the grinding wheel 5 may also fix or release the grinding wheel chuck 4 or the grinding wheel 5 .

[0086] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0087] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
