Description

Technical Field

[0002] Automated grinding equipment is a device used for the automated grinding and polishing of workpiece surfaces. It is widely used in manufacturing, where it can save significant labor costs and improve production efficiency and product quality. Existing automated grinding equipment typically uses a multi-axis robot or robotic arm as its axis, with multiple abrasive belts and / or grinding heads of different roughness arranged around it. The robot or robotic arm holds the product and brings it close to the abrasive belts or grinding heads to grind the product.

[0003] This wraparound layout, driven by a central robot or robotic arm, can only polish one product at a time. While it improves polishing efficiency compared to manual polishing, it still cannot meet the needs of mass production. Furthermore, its equipment utilization rate is low; only one sanding belt or polishing head is operational during each robot or robotic arm movement, while the others remain idle. It also occupies a significant amount of space. Moreover, the programming of the robot or robotic arm in this wraparound layout is quite complex. Specifically, the robot or robotic arm needs to perform a programming positioning step to move the part close to the sanding belt and / or polishing head with the first roughness, and another programming positioning step to move close to the sanding belt and / or polishing head with the next roughness. Therefore, the programming is complex and time-consuming. Utility Model Content

[0028] Example

[0029] Combination Figures 1 to 6 As shown, this embodiment provides an integrated multi-functional grinding device, including multiple multi-axis clamping devices 22 for clamping parts and driving the parts closer to or away from the grinding device.

[0030] In this embodiment, there are two vertically arranged turntables 1 and 2, and a first drive 3 and a second drive 4.

[0031] Multiple multi-axis clamping devices are symmetrically arranged on the outer periphery of the turntable; multiple grinding devices are symmetrically arranged on the first turntable 1 and the second turntable 2 along their circumference; wherein the grinding device on the first turntable 1 is a first belt sander 6; a first drive 3 is provided on the first turntable 1, which can synchronously drive the sanding belts 10 of the multiple first belt sanders 6 to rotate; the second drive 4 can drive the turntable to rotate, thereby driving the grinding device to rotate in a circumferential position.

[0032] By setting up a vertical turntable, a vertical switching grinding device can be realized. Multiple multi-axis clamping devices 22 can be set on the outer periphery of the turntable to realize the simultaneous grinding and processing of multiple parts. This greatly reduces the situation where one grinding device is working while the others are idle, significantly improving the utilization rate of the grinding device and increasing processing efficiency, enabling mass production; and the entire equipment has a high space utilization rate.

[0033] Specifically, the turntable is rotatably mounted on the base 5. The first belt sander 6 includes a Y-shaped bracket 8 mounted on the first turntable 1 and adjustable along the radial direction of the turntable. The bracket is mounted on the turntable via a detachable connecting plate 9. Driven wheels 11 are mounted on both ends of the outer side, and a transmission wheel 12, connected to the first drive 3, is mounted on the other end of the turntable. The sanding belt 10 is tensioned and surrounded by the driven wheels 11 and the transmission wheel 12. The first drive 3, a motor, is fixed to the base 5. A first driving multi-wedge pulley 13 is mounted on the motor. A second driving multi-wedge pulley 14 is mounted on the axis of the turntable via a bearing and is connected to the first driving multi-wedge pulley 13 via a multi-wedge belt 15. The drive wheel 12 is connected to one end of the sanding belt drive shaft, which is connected to the turntable via bearings. The other end of the drive shaft is connected to a driven multi-ribbed pulley 23. The second driving multi-ribbed pulley 14 is connected to the driven multi-ribbed pulley 23 via a multi-ribbed belt 15, thereby driving the driven multi-ribbed pulley 23 to rotate, which in turn drives the sanding belt 10 to rotate. The Y-shaped bracket 8 can be moved and adjusted radially along the turntable via a third drive or manually, so that the driven wheel 11 moves closer to or further away from the drive wheel 12, thereby adjusting the tension of the sanding belt 10.

[0034] Preferably, in other embodiments, such as Figure 4 As shown, the Y-shaped support 8 is moved and adjusted by a cylinder 26; and the base 5 is equipped with an air source distributor 27 connected to the cylinder 26, which is controlled by a proportional valve. Specifically, the grinding pressure is set according to different grinding processes. When the multi-axis clamping device moves the workpiece to the initial position of contacting the sanding belt, if the proportional valve senses that the grinding pressure is not up to the set pressure, the proportional valve controls the cylinder 26 to drive the Y-shaped support to move radially outward in a fine adjustment, so that the sanding belt is further tensioned and the workpiece is pressed tightly to achieve the required grinding pressure.

[0035] Of course, it should be noted that in other embodiments, there may be only one turntable, with multiple first belt sanders 6 arranged symmetrically around the turntable for polishing the outer surface of the product.

[0036] Preferably, the Y-shaped bracket 8 is further provided with a plurality of tensioning rollers 16, and the sanding belt 10 is wound around the plurality of tensioning rollers 16, which can increase the length of the sanding belt 10, increase the sanding efficiency, and extend the service life of the sanding belt 10. At the same time, the tensioning rollers 16 can also further adjust the tension of the sanding belt 10.

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

[0038] In the first embodiment, there are two second drives 4, which drive the first turntable 1 and the second turntable 2 to rotate respectively. Four first belt sanders 6 are symmetrically arranged on the first turntable 1, and four pneumatic grinding heads 7 are symmetrically arranged on the second turntable 2.

[0039] In this embodiment, as Figures 1 to 3 As shown, the turntable is fixed to the horizontal platform via 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 opposite sides of the second turntable 2; and the sanding belts 10 and pneumatic grinding heads 7 on each of the first belt sanders 6 have different roughnesses. Taking the first belt sander 6 on the first turntable 1 and the pneumatic grinding head 7 on the second turntable 2 as an example, initially, the roughness of the sanding belt 10 or grinding head on the left or right grinding device is the largest, and the roughness decreases sequentially clockwise or counterclockwise. The following describes a feasible grinding process for parts requiring surface and groove side polishing, using the example of the sanding belt 10 or grinding head on the left grinding device having the largest roughness, decreasing sequentially clockwise:

[0040] First, the left first multi-axis clamping device 17 and the right first multi-axis clamping device 18 clamp the part respectively. At this time, the left first multi-axis clamping device 17 drives the part to approach the rotating first roughness sanding belt 10 for grinding the outer surface of the part. Then, the second drive 4 drives the first turntable 1 to rotate 90 degrees counterclockwise. At this time, the first sander 6 of the second roughness rotates to the left position, and the left first multi-axis clamping device 17 again drives the part to approach the rotating second roughness sanding belt 10 for fine grinding. In this way, the left first multi-axis clamping device 17 drives the part to complete the grinding of the four roughness sanding belts 10 in sequence. At the same time, after the first turntable 1 rotates 180 degrees, the first sander 6 of the first roughness is placed on the right side, and the right first multi-axis clamping device 18 holds the part close to the first roughness sanding belt 10 for grinding. Similarly, the right first multi-axis clamping device 18 drives the part to complete the grinding of the four roughness sanding 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) moves the part closer to the first roughness polishing head for polishing the side of the groove; then the second drive 4 moves the second turntable 2 counterclockwise by 90 degrees, at which time the pneumatic polishing head 7 of the second roughness rotates to the left position, and the left second multi-axis clamping device again moves the part closer to the rotating second roughness polishing head for fine polishing; and so on, the right second multi-axis clamping device (not shown in the attached figure) moves the part to complete the polishing of the four roughness polishing heads in sequence. At the same time, after the second turntable 2 rotates 180 degrees, the pneumatic polishing 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 polishing head for polishing; similarly, the right second multi-axis clamping device moves the part to complete the polishing of the four roughness polishing heads in sequence.

[0042] In the 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 to say, at least two first belt sanders 6 and the pneumatic grinding mechanism are working each time, which improves the utilization rate of the grinding device and improves the processing efficiency.

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

[0044] In the second embodiment, as Figure 5 As shown, the turntable is horizontally fixed on a horizontal surface by a bracket, and four multi-axis clamping devices 22 are symmetrically arranged around 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 increasing processing efficiency.

[0045] Of course, in other embodiments, such as Figure 6 As shown, the turntable can also be suspended from the top via the lifting rail 19. The multi-axis clamping devices 22 can be installed 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 embodiments and will not be described in detail here.

[0046] In a further preferred embodiment, the belt sanding zones of multiple belt sanders are positioned at equidistant circumferential locations on the turntable. The belt sanding zone is the area that contacts the workpiece to be sanded. Specifically, with... Figure 2 and Figure 5 To illustrate specifically, taking the station where the multi-axis robot or manipulator on the left is located as the first grinding station as an example, the belt sander rotates to the first grinding station, and the sanding belt placed vertically between the two driven wheels 11 forms the belt sanding area. When the robot or manipulator on the left clamps the part close to the belt sanding area, the part slides against the sanding belt of the first roughness to achieve grinding. Then, the part remains in the Y and Z directions under the clamping of the robot or manipulator. The turntable rotates to move the next belt sander to the first grinding station. At this time, the belt sanding area of ​​the second roughness sanding belt is in the same position as the previous belt sanding area of ​​the first roughness sanding belt, that is, it is located on the circumference with the same radial distance of the turntable. At this time, it is only necessary to make fine adjustments by driving the robot or manipulator along the X direction through the base 20 to make the part slide against the sanding belt of the second roughness to achieve grinding.

[0047] In this configuration, the sanding zones of multiple belt sanders are positioned at equidistant circumferential locations on a turntable. After the robot or robotic arm performs a positioning maneuver on the part, it can either control the cylinder via the proportional valve to fine-tune and tension the sanding belt, maintaining the sanding pressure between the belt and the part for efficient sanding; or it can use the base 20 to move the robot or robotic arm closer to the sanding belt to maintain the sanding pressure and improve sanding efficiency. This method requires only one programming session for the robot or robotic arm's actions, and the program is relatively simple. Multiple machines can share the same program, reducing programming time.

[0048] The multi-axis clamping device can be a multi-axis robot or manipulator, mounted on a base 20 that can move along the X, Y, and Z directions, giving it more degrees of freedom and enabling it to better drive the parts for grinding. Furthermore, in other embodiments, such as... Figure 4 As shown, the grinding device on the second turntable 2 can also be a second belt sander 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 belt sander 6 and the second belt sander 21 to rotate, so as to simultaneously grind the outer surfaces of multiple parts.

[0049] This utility model provides an integrated multi-functional grinding equipment. The multi-axis clamping device only needs to hold the workpiece close to or away from its grinding station. The vertical turntable allows for switching between different roughness grinding devices, significantly saving space. Furthermore, multiple multi-axis clamping devices can be arranged around the turntable, enabling simultaneous grinding of multiple parts. This avoids situations where one grinding device is operating while others are idle, greatly improving the utilization rate of the grinding equipment, increasing processing efficiency, and enabling mass production.
