Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0028] Example

[0029] Combination Figures 1 to 6 As shown, this embodiment provides an integrated multifunctional grinding device, including a plurality of multi-axis clamping devices 22 for clamping parts and capable of driving the parts to approach or move away from the grinding device.

[0030] In this embodiment, there are two vertical and oppositely arranged first turntable 1 and second turntable 2, as well as first drive 3 and second drive 4;

[0031] A plurality of the multi-axis clamping devices are symmetrically arranged on the outer circumference of the turntable; a plurality of the grinding devices are symmetrically arranged on the first turntable 1 and the second turntable 2 along their circumferential directions; wherein the grinding device on the first turntable 1 is a first sanding belt mechanism 6; a first drive 3 is arranged on the first turntable 1, which can synchronously drive the sanding belts 10 of the plurality of the first sanding belt mechanisms 6 to rotate; the second drive 4 can respectively drive the turntable to rotate, and then drive the grinding device to rotate in a circumferential position.

[0032] By setting up a vertical turntable, a vertical switching grinding device is realized, and multiple multi-axis clamping devices 22 can be set on the periphery of the turntable to realize synchronous grinding processing of multiple parts, which greatly reduces the situation where one grinding device is in operation and the others are idle, greatly improves the utilization rate of the grinding device, improves processing efficiency, and can realize large-scale production; and the space utilization rate of the entire equipment is high.

[0033] Specifically, the turntable is rotatably arranged on the base 5. The first sanding belt mechanism 6 includes a Y-shaped bracket 8 arranged on the first turntable 1 and capable of being moved and adjusted along the radial direction of the turntable, which is arranged on the turntable through a detachable connecting plate 9; driven wheels 11 are arranged on the two ends of the outer end, and a transmission wheel 12 connected to the first drive 3 is arranged on the turntable at the other end; the sanding belt 10 is tensioned and arranged around the driven wheel 11 and the transmission wheel 12. The first drive 3 is fixed on the base 5, which is a motor, and a first active multi-V belt pulley 13 is arranged on the motor. A second active multi-V belt pulley 14 is arranged on the axis of the turntable through a bearing, and is connected to the first active multi-V belt pulley 13 through a multi-V belt 15. The transmission wheel 12 is connected to one end of the sand belt transmission shaft, and the sand belt transmission shaft is connected to the turntable through a bearing, and the other end of the sand belt transmission shaft is connected to a driven multi-V belt pulley 23; the second driving multi-V belt pulley 14 is connected to the driven multi-V belt pulley 23 through a multi-V belt 15, thereby driving the driven multi-V belt pulley 23 to rotate, and then driving the sand belt 10 to rotate. The Y-shaped bracket 8 can be moved and adjusted along the radial direction of the turntable through a third drive or manually, so that the driven wheel 11 is close to or away from the transmission wheel 12, thereby adjusting the tightness of the sand belt 10.

[0034] Preferably, in other embodiments, Figure 4 As shown, the Y-shaped bracket 8 is moved and adjusted by the cylinder 26; and the base 5 is provided with an air source distributor 27 connected to the cylinder 26 and controlled by a proportional valve. Specifically, the grinding pressure is set according to different grinding processes. When the multi-axis clamping device clamps the part and moves to the initial position against the abrasive belt, when the proportional valve senses that the grinding pressure does not reach the set pressure, the proportional valve controls the cylinder 26 to drive the Y-shaped bracket to move radially outwards for fine adjustment, so that the abrasive belt is further tightened and the part is pressed to reach the pressure required for grinding.

[0035] Of course, it should be noted that, in other embodiments, there may be only one turntable, and a plurality of the first sanding belt mechanisms are symmetrically arranged around the turntable to grind the outer surface of the product.

[0036] Preferably, the Y-shaped bracket 8 is further provided with a plurality of tension wheels 16, and the abrasive belt 10 is wound around the plurality of tension wheels 16, which can increase the length of the abrasive belt 10, increase the grinding efficiency and improve the service life of the abrasive belt 10. At the same time, the tension wheel 16 can also further adjust the tightness of the abrasive belt 10.

[0037] The second drive 4 is also a motor, on which a driving tooth 24 is arranged, and the outer circumference of the turntable is provided with a driven tooth 25 meshing with the driving tooth, thereby driving the turntable to rotate and driving the grinding device to rotate the circumferential position.

[0038] In the first embodiment, two second drives 4 are included to respectively drive the first turntable 1 and the second turntable 2 to rotate. The first turntable 1 is symmetrically provided with four first sanding belt mechanisms 6, and the second turntable 2 is symmetrically provided with four pneumatic grinding heads 7.

[0039] In this embodiment, if Figures 1 to 3 As shown, the turntable is fixed on the horizontal surface through the base 5; two first multi-axis clamping devices are symmetrically arranged on both sides of the first turntable 1, and two second multi-axis clamping devices are symmetrically arranged on the opposite sides of the second turntable 2; and the sanding belt 10 and the pneumatic grinding head 7 on each sanding belt mechanism have different roughness. Take the first sanding belt mechanism 6 set on the first turntable 1 and the pneumatic grinding head 7 set on the second turntable 2 as an example, and the initial state is that the roughness of the sanding belt 10 or the grinding head of the grinding device placed on the left or right is the largest, and the roughness decreases clockwise or counterclockwise. The following takes the example that the roughness of the sanding belt 10 or the grinding head of the grinding device on the left is the largest and decreases clockwise; a feasible grinding process for a part that needs to be polished and polished on the surface and the side of the groove is described:

[0040] First, the left first multi-axis clamping device 17 and the right first multi-axis clamping device 18 clamp the parts respectively, and the left first multi-axis clamping device 17 drives the parts close to the rotating first roughness abrasive belt 10 to grind the outer surface of the parts; then the second drive 4 drives the first turntable 1 to rotate 90 degrees counterclockwise, and the first abrasive belt mechanism 6 of the second roughness rotates to the left position, and the left first multi-axis clamping device 17 drives the parts close to the rotating second roughness abrasive belt 10 for fine grinding; by analogy, the left first multi-axis clamping device 17 drives the parts to complete the grinding of the four roughness abrasive belts 10 in sequence. At the same time, after the first turntable 1 rotates 180 degrees, the first abrasive belt mechanism 6 of the first roughness is placed on the right, and the right first multi-axis clamping device 18 holds the parts close to the first roughness abrasive belt 10 for grinding; similarly, the right first multi-axis clamping device 18 drives the parts to complete the grinding of the four roughness abrasive belts 10 in sequence.

[0041] Then, after the outer surface of the part is polished, the left second multi-axis clamping device (not shown in the attached figure) drives the part close to the first roughness grinding head to polish the side of the groove; then the second drive 4 drives the second turntable 2 to rotate counterclockwise 90 degrees, at which time the pneumatic grinding head 7 of the second roughness rotates to the left position, and the left second multi-axis clamping device drives the part close to the rotating second roughness grinding head for fine grinding again; by analogy, the right second multi-axis clamping device (not shown in the attached figure) drives the part to complete the grinding of the four roughness grinding heads in sequence. At the same time, after the second turntable 2 rotates 180 degrees, the pneumatic grinding head 7 of the first roughness is placed on the right, and the right second multi-axis clamping device holds the part close to the first roughness grinding head for grinding; similarly, the right second multi-axis clamping device drives the part to complete the grinding of the four roughness grinding heads in sequence.

[0042] As described above, after the first turntable 1 and the second turntable 2 rotate 180 degrees, the two first multi-axis clamping devices and the second multi-axis clamping devices simultaneously drive the parts to perform grinding operations, that is, at least two of the first sanding belt mechanisms 6 and the pneumatic grinding mechanisms are used for each grinding operation, thereby improving the utilization rate of the grinding device and improving the processing efficiency.

[0043] Of course, in other embodiments, the above feasible grinding process may also be that the first multi-axis clamping device and the second multi-axis clamping device clamp the parts simultaneously, grind the outer surface and the groove side at the same time, and then perform alternating grinding to further reduce the idle time of the grinding device.

[0044] In the second embodiment, if Figure 5 As shown, the turntable is horizontally fixed on a horizontal plane by a bracket, and four multi-axis clamping devices 22 are symmetrically arranged on the opposite sides of the turntable. The processing method of this embodiment is similar to that of the first embodiment, except that after the turntable rotates 270 degrees, the four multi-axis clamping devices 22 can start working together, further improving the utilization rate of the grinding device and improving the processing efficiency.

[0045] Of course, in other embodiments, such as Figure 6 As shown, the turntable can also be hoisted and hoisted on the top by the lifting rail 19. The multi-axis clamping device 22 can be respectively provided on the left and right sides and the bottom of the turntable to clamp the parts for simultaneous grinding. The processing steps are similar to those in the above embodiment and will not be elaborated here.

[0046] In the above, it is further preferred that the sanding belt grinding areas of the multiple sanding belt mechanisms are placed at circumferential positions with the same radial distance on the turntable. The sanding belt grinding area is the area that contacts the workpiece to be ground. Figure 2 and Figure 5 To explain in detail, take the position of the multi-axis robot or manipulator on the left as the first grinding position as an example, the sanding belt mechanism rotated to the first grinding position, and the sanding belt arranged in the vertical direction between the two driven wheels 11 is the sanding belt grinding area. When the robot or manipulator on the left clamps the part close to the sanding belt grinding area, so that the part and the sanding belt of the first roughness are in relative sliding contact to achieve grinding, then the part maintains the position in the Y direction and the Z direction unchanged under the clamping of the robot or manipulator; and the turntable rotates to rotate the next sanding belt mechanism to the first grinding position, at this time, the sanding belt grinding area of ​​the second roughness sanding belt is in the same position as the sanding belt grinding area of ​​the first roughness sanding belt before, that is, it is located at the circumferential position with the same radial distance of the turntable; at this time, it is only necessary to drive the robot or manipulator along the X direction through the base 20 to make fine adjustments, so that the part and the sanding belt of the second roughness are in relative sliding contact to achieve grinding.

[0047] In the above, the sanding belt grinding areas of multiple sanding belt mechanisms are placed on the circumferential position with the same radial distance on the turntable. After the robot or manipulator drives the part to be positioned once, it can be controlled by the proportional valve to drive the sanding belt to move finely and tighten the cylinder to keep the sanding belt and the part to achieve efficient grinding; or it can be driven by the base 20 to move the robot or manipulator in the direction close to the sanding belt to keep the sanding belt and the part to improve the grinding efficiency. The program for realizing the action of the robot or manipulator in this way only needs to be programmed once, and the program is relatively simple. The programs of multiple machines can be directly shared, shortening the programming time.

[0048] The multi-axis clamping device can be a multi-axis robot or manipulator, which is arranged on a base 20 that can move along the X, Y, and Z directions, so that it has more degrees of freedom and can drive the parts to be polished. In other embodiments, such as Figure 4 As shown, the grinding device on the second turntable 2 can also be a second sanding belt mechanism 21, whose sanding belt 10 is synchronously driven to rotate by the first drive 3. The first drive 3 adopts a motor with two output shafts to synchronously drive the sanding belts 10 of the first sanding belt mechanism 6 and the second sanding belt mechanism 21 to rotate, so as to achieve simultaneous grinding of the outer surfaces of multiple parts.

[0049] The integrated multifunctional grinding equipment provided by the present invention has a multi-axis clamping device that only needs to clamp the parts close to or away from the grinding station where they are located; the vertical turntable is used to switch between grinding devices with different roughnesses, which greatly saves the space occupied by the equipment. At the same time, multiple multi-axis clamping devices can be arranged on the periphery of the turntable to achieve simultaneous grinding of multiple parts, avoiding the situation where one grinding device is in operation while the others are idle, greatly improving the utilization rate of the grinding device and the processing efficiency, and realizing mass production.
