Description

Technical Field

[0001] The utility model relates to a blade disk servo force-controlled sand belt grinder, belonging to the technical field of grinding equipment. Background Art

[0002] Polishing is a process that uses mechanical, chemical, or electrochemical processes to reduce the surface roughness of a product to create a bright, smooth surface. The quality of the polished product directly affects its performance and lifespan.

[0003] Belt grinding is one of the commonly used grinding methods, but the existing belt grinder is generally composed of a drive motor, a grinding wheel and a sanding belt. The sanding belt is connected between the drive motor and the grinding wheel, and the drive motor drives the sanding belt to rotate for grinding. However, since the positions of the drive motor and the grinding wheel are relatively fixed, the sanding belt between the two is difficult to install and remove if it is too tight, and easy to fall off if it is too loose, affecting the quality and grinding efficiency of the product. In addition, switching the grinding position requires moving the entire grinder, which is cumbersome to operate and has low grinding efficiency. Utility Model Content

[0026] Please refer to Figures 1 to 2 The blade disk servo force-controlled belt grinder shown in an embodiment of the present application includes a grinding mechanism 10, a swing mechanism 30 and a quick-change mechanism.

[0027] The grinding mechanism 10 includes a grinding head 12 , a driving member 11 and a grinding belt 13 connected between the grinding head 12 and the driving member 11 . The driving member 11 is used to drive the grinding belt 13 to rotate on the grinding head 12 .

[0028] In this embodiment, the main body of the grinding head 12 includes a connecting end 121 that is detachably connected to the pushing assembly and a grinding end 122 that is detachably connected to the connecting end 121. The connecting end 121 is in the shape of an elongated strip and is provided with two connecting holes 1211 along its length. It is installed on the pushing assembly by bolts so that the connecting end 121 can be quickly replaced after being broken or damaged to avoid affecting production. A clamping structure is provided between the connecting end 121 and the grinding end 122. The clamping structure includes a clamping block 1212 formed at the end of the connecting end 121 and a clamping groove 1222 formed on the grinding end 122. The grinding end 122 is partially overlapped on the connecting end 121, and a threaded connection structure is formed on the overlapping portion to ensure its stability in the future and easy installation and disassembly.

[0029] In this embodiment, the grinding end 122 includes a connector and a grinding wheel 1221 disposed at the end of the connector. The grinding belt 13 is connected between the grinding wheel 1221 and the driving member 11. The grinding wheel 1221 is connected to the end of the grinding end 122 via a rotating shaft and partially extends beyond the end of the grinding end 122. The grinding belt 13 is connected between the grinding wheel 1221 and the driving member 11 and rotates under the drive of the driving member 11.

[0030] In this embodiment, the driving member 11 includes a driving motor and a driving wheel 14 disposed on the output shaft of the driving motor. The grinding belt 13 is connected between the driving wheel 14 and the grinding wheel 1221 and rotates under the drive of the driving motor to perform grinding. The structure is simple and easy to operate.

[0031] The swing mechanism 30 is connected to the grinding mechanism 10 to drive the grinding mechanism 10 to swing. In this embodiment, the swing mechanism 30 includes a swing motor 31 and a support base 32 mounted on the housing of the swing motor 31. The support base is formed with a fixing hole 321 for connecting to a robot. The provision of the support base 32 facilitates the connection and fixing of the blade disc servo force-controlled belt grinder to the robot, thereby expanding its applicability.

[0032] The quick-change mechanism includes a push assembly connected to the grinding head 12 and a clamping assembly 22 disposed on the push assembly and located outside the grinding belt. The push assembly has a first position for driving the grinding head 12 away from the driving member 11 and a second position for driving the grinding head 12 toward the driving member 11. In the first position, the grinding belt 13 is in a tensioned state, and the clamping assembly 22 abuts against the grinding belt 13 to move the grinding belt 13 toward the grinding head 12. In the second position, the grinding belt 13 is in a relaxed state, and the clamping assembly 22 releases the grinding belt 13.

[0033] In this embodiment, the clamping assembly 22 is a pair of rollers disposed outside the sanding belt 13. By disposing the pair of rollers outside the sanding belt 13, when the thrust assembly drives the sanding head 12 to move to the first position, the rollers abut against the middle of the sanding belt 13, so that the abutted point of the sanding belt 13 is as close to the sanding head 12 as possible, with the sanding belt 13 between the ends of the sanding head 12. This can further tighten the sanding belt 13 and reduce the vibration amplitude of the sanding belt 13.

[0034] In this embodiment, the pushing assembly includes a pushing cylinder 21 and a connecting block 24 connected between the pushing cylinder 21 and the grinding head 12. The pushing cylinder 21 drives the connecting block 24 to move the grinding head 12, thereby tightening or loosening the grinding belt 13, thereby facilitating the installation and removal of the grinding belt 13 and grinding.

[0035] In this embodiment, a guide structure is formed between the connecting block 24 and the pushing cylinder 21. The guide structure includes a slide rail 211 formed on the housing of the pushing cylinder 21 and a slider 23 connected between the slide rail 211 and the connecting block 24. The provision of the guide structure can maintain a consistent pushing direction, thereby facilitating positioning of the end of the grinding head 12.

[0036] The present application sets a swing mechanism to drive the grinding mechanism to swing, so that the grinding mechanism can be rotated at any time when the grinding position needs to be switched, and sets a pushing assembly to drive the grinding head to switch between a first position away from the driving member and a second position close to the driving member, so as to facilitate the replacement of the sanding belt or tensioning the sanding belt. At the same time, a clamping assembly provided on the pushing assembly and located on the outside of the sanding belt is used to push the sanding belt toward the sanding head when the sanding head is in the first position, further tensioning the sanding belt, preventing the sanding belt from shaking during the sanding process, and improving the sanding quality and efficiency.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
