Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Example

[0026] like Figures 1-6 As shown, a grinding device for coupling production includes: a grinding table 1, a support platform 101 mounted on the top of the grinding table 1, a fixing frame 102 mounted on the top of the support platform 101, a grinding assembly disposed on the support platform 101, the grinding assembly including: a rotary motor 3, a motor shaft 301, a rotating shaft 302, an arc-shaped grinding block 303 and a sandpaper grinding layer 304, and a disassembly assembly disposed on the top of the support platform 101, the disassembly assembly including: a connecting block 4, an insert block 401, a limiting protrusion 402, a movable groove 403, a movable hole 404, a pull rod 405, a spring 406, a pressure block 407 and a limiting recess 408.

[0027] Among them, a fixed block 2 is fixedly installed on one side of the top of the support platform 101. A right limiting cylinder 201 is provided on one side of the fixed block 2. A movable block 202 is provided on one side of the fixed block 2. A left limiting cylinder 203 is provided on one side of the top of the movable block 202. The top of the left limiting cylinder 203 and the right limiting cylinder 201 are provided with screw holes. An adjusting screw 204 is threaded inside the screw holes. An arc-shaped clamping block 205 is provided inside the left limiting cylinder 203 and the right limiting cylinder 201. The adjusting screw 204 passes through the screw hole and is rotatably connected to the arc-shaped clamping block 205 through a bearing.

[0028] When grinding the coupling, insert one end of the coupling into the right limiting cylinder 201, grasp the adjusting screw 204 and rotate it clockwise. The adjusting screw 204 rotates inside the screw hole, pushing the arc-shaped clamping block 205 downward to contact the connecting end of the coupling. The bottom of the right limiting cylinder 201 clamps and fixes the connecting end of the coupling. When fixing the other end of the coupling, drive the movable block 202 to move towards the fixed block 2, so that the left limiting cylinder 203 moves to the other end of the coupling. At this time, the other end of the coupling is placed inside the left limiting cylinder 203. Grasp the adjusting screw 204 and rotate it clockwise. The adjusting screw 204 rotates inside the screw hole, pushing the arc-shaped clamping block 205 downward to contact the connecting end of the other end of the coupling. The bottom of the right limiting cylinder 201 clamps and fixes the connecting end of the other end of the coupling. Thus, the coupling is clamped and fixed, so that the coupling is located at the bottom of the arc-shaped grinding block 303.

[0029] An electric push rod 5 is installed on one side of the top of the support platform 101. The electric push rod 5 is connected to the movable block 202. A sliding groove 501 is opened on the top of the support platform 101. A movable block 502 that is slidably connected to the sliding groove 501 is installed at the bottom of the movable block 202. When the movable block 202 is used to clamp the coupling, the electric push rod 5 is activated to push the movable block 202 to move towards the fixed block 2. After the movable block 202 is subjected to force, the movable block 502 at the bottom of the movable block 202 moves in the sliding groove 501 to avoid wear and damage between the movable block 202 and the support platform 101.

[0030] Among them, a rotary motor 3 is fixedly installed on the top of the movable block 202 by bolts. The output end of the rotary motor 3 is driven and connected to the motor shaft 301. One end of the motor shaft 301 is connected to the left limit cylinder 203. The right limit cylinder 201 and the fixed block 2 are rotatably connected by a rotating shaft 302 through a bearing. The bottom of the fixed frame 102 is provided with an arc-shaped grinding block 303. A sandpaper grinding layer 304 is installed inside the arc-shaped grinding block 303.

[0031] After the coupling is clamped and fixed on the support platform 101, the arc-shaped grinding block 303 is driven to move downward to the top of the coupling, so that the sandpaper grinding layer 304 inside the arc-shaped grinding block 303 comes into contact with the coupling. At this time, the rotary motor 3 is started to drive the motor shaft 301 to rotate. The motor shaft 301 drives the left limit cylinder 203 to rotate, that is, the left limit cylinder 203 drives the coupling, the right limit cylinder 201 and the rotating shaft 302 to rotate. During the rotation of the coupling, the sandpaper grinding layer 304 grinds the surface of the coupling, thereby reducing the surface roughness of the coupling and making the surface of the coupling smooth. Moreover, the arc-shaped grinding block 303 fits into the coupling, which speeds up the grinding speed of the coupling and improves the grinding efficiency.

[0032] The top of the fixed frame 102 is fixed with a telescopic cylinder 305 by bolts. The bottom of the telescopic cylinder 305 is connected to a telescopic rod 306. The bottom end of the telescopic rod 306 is connected to the insert block 401. When the arc-shaped grinding block 303 is in use, it is movably connected to the insert block 401 through the top connecting block 4. The insert block 401 is installed at the bottom end of the telescopic rod 306, so that the telescopic rod 306, the insert block 401, the connecting block 4, and the arc-shaped grinding block 303 form a whole. During the use of the arc-shaped grinding block 303, the telescopic cylinder 305 is activated to drive the telescopic rod 306 to move downward. The telescopic rod 306 pushes the insert block 401, the connecting block 4, and the arc-shaped grinding block 303 to move downward, so that the arc-shaped grinding block 303 contacts the coupling, which facilitates the grinding of the coupling. After the grinding is completed, the telescopic rod 306 drives the insert block 401, the connecting block 4, and the arc-shaped grinding block 303 to move upward.

[0033] The grinding table 1 has multiple chip removal grooves 6 on its top and a waste bin 601 at the bottom of its interior. When grinding the coupling, the chips generated during grinding fall into the chip removal grooves 6 and are collected in the waste bin 601, which facilitates chip collection and processing.

[0034] The grinding table 1 has a support plate 7 fixedly installed on its outer end by bolts. The top of the support plate 7 has a groove 701. When the grinding table 1 is in use, the coupling can be temporarily placed on the support plate 7 and the groove 701 limits the placement of the coupling to prevent it from rolling and falling.

[0035] The arc-shaped grinding block 303 has a connecting block 4 fixedly installed on its top. The connecting block 4 has an insert 401 on its top. Limiting protrusions 402 are installed on both sides of the top of the connecting block 4. The insert 401 has movable grooves 403 on both sides inside. The movable grooves 403 have two movable holes 404 inside. The two movable holes 404 are movably connected to the pull rod 405. A spring 406 is sleeved on the pull rod 405. The spring 406 is tightly fitted with one of the movable holes 404. A pressure block 407 is installed on the other end of the spring 406. The pressure block 407 is tightly fitted with the other movable hole 404. A limiting recess 408 that matches the limiting protrusion 402 is fixedly installed on the inner end of the pull rod 405.

[0036] When installing and using the arc-shaped grinding block 303, insert the connecting block 4 at the top of the arc-shaped grinding block 303 into the insert block 401. When pushing the arc-shaped grinding block 303 upward, the limiting protrusions 402 on both sides of the top of the connecting block 4 come into contact with the limiting recesses 408 at the inner end of the pull rod 405. Continuously push the connecting block 4 upward, and the limiting protrusions 402 press the limiting recesses 408 upward. After the limiting recesses 408 are subjected to force, they push the pull rod 405 to move to the left and right sides respectively within the movable hole 404 inside the movable groove 403. At this time, the pressure block 407 presses the spring 406. After compression, the pull rod 405 moves out of the outer ends of the insert block 401. As the connecting block 4 drives the limiting protrusion 402 to move upward, it will be misaligned with the limiting concave block 408 and located at the top of the limiting concave block 408. At this time, the spring 406 is not under force, and the spring force generated by the deformation will push the limiting concave block 408 back to its original position and pull the connecting block 4 downward, so that the limiting protrusion 402 is locked and fixed at the limiting concave block 408. Magnetic blocks are embedded in the bottom of the limiting concave block 408 and the bottom of the limiting protrusion 402, thereby strengthening the connection between the limiting concave block 408 and the limiting protrusion 402.

[0037] The contact point between the limiting protrusion 402 and the limiting concave block 408 is set with an arc angle, which can reduce resistance friction and make it easy to slide after contact.

[0038] When the arc-shaped grinding block 303 needs to be replaced, push the arc-shaped grinding block 303 upward, so that the connecting block 4 moves upward inside the insert block 401. At this time, the limiting protrusion 402 is subjected to force and separates from the limiting concave block 408. Another worker grabs the pull rod 405 and pulls it out to both sides of the outer end of the insert block 401. The pull rod 405 moves in the movable hole 404 inside the movable groove 403. At this time, the pressure block 407 presses and compresses the spring 406. After the pull rod 405 moves out to both sides of the outer end of the insert block 401, the arc-shaped grinding block 303 can be pulled out downward, which makes it easy to replace the arc-shaped grinding block 303. It can be used for couplings of different lengths and sizes. This snap-fit ​​disassembly and assembly method is quick and convenient, and has good stability. It solves the problem that bolt installation is prone to wear and stripping, which leads to the grinding block easily loosening and falling off.

[0039] Working principle:

[0040] When grinding the coupling, insert one end of the coupling into the right limiting cylinder 201, grasp the adjusting screw 204 and rotate it clockwise. The adjusting screw 204 rotates inside the screw hole, pushing the arc-shaped clamping block 205 downward to contact the connecting end of the coupling. The bottom of the right limiting cylinder 201 clamps and fixes the connecting end of the coupling. When fixing the other end of the coupling, drive the movable block 202 to move towards the fixed block 2, so that the left limiting cylinder 203 moves to the other end of the coupling. At this time, the other end of the coupling is placed inside the left limiting cylinder 203. Grasp the adjusting screw 204 and rotate it clockwise. The adjusting screw 204 rotates inside the screw hole, pushing the arc-shaped clamping block 205 downward to contact the connecting end of the other end of the coupling. The bottom of the right limiting cylinder 201 clamps and fixes the connecting end of the other end of the coupling. Thus, the coupling is clamped and fixed, so that the coupling is located at the bottom of the arc-shaped grinding block 303.

[0041] After the coupling is clamped and fixed on the support platform 101, the arc-shaped grinding block 303 is driven to move downward to the top of the coupling, so that the sandpaper grinding layer 304 inside the arc-shaped grinding block 303 comes into contact with the coupling. At this time, the rotary motor 3 is started to drive the motor shaft 301 to rotate. The motor shaft 301 drives the left limit cylinder 203 to rotate, that is, the left limit cylinder 203 drives the coupling, the right limit cylinder 201 and the rotating shaft 302 to rotate. During the rotation of the coupling, the sandpaper grinding layer 304 grinds the surface of the coupling, thereby reducing the surface roughness of the coupling and making the surface of the coupling smooth. The arc-shaped grinding block 303 fits with the coupling, which speeds up the grinding speed of the coupling and improves the grinding efficiency. When grinding the coupling, the grinding debris falls into the chip discharge groove 6 and is collected in the waste bin 601 through the chip discharge groove 6, which facilitates the collection and treatment of debris.
