Description

Technical Field

[0001] This utility model relates to the field of grinding devices, and in particular to a grinding device. Background Technology

[0002] The grinding device for generator injection molded parts is a device used to clean and finely process defects such as burrs, flash, and rough parts on the generator housing and its accessories after injection molding.

[0003] When using a grinder to grind the surface of a generator injection molded part, the part is usually placed in a fixture on the grinder and fixed. Then, the corresponding grinding disc is screwed into the inner wall of the threaded groove rod and fixed in place. During grinding, the drive motor is started to rotate the threaded groove rod and the grinding disc, and then the grinder is started to move the robotic arm. This causes the grinding disc to change its angle and position to grind the surface of the generator injection molded part. Since the grinding disc is directly exposed during use or when not in use, when manually adjusting the position and angle of the generator injection molded part, the grinding disc may be accidentally touched, causing scratches and posing a certain safety hazard during use. Utility Model Content

[0004] The technical problem this utility model aims to solve is that, since the grinding disc is directly exposed during use or when not in use, when manually adjusting the position and angle of the generator injection molded parts, the grinding disc may be accidentally touched, causing scratches, which leads to certain safety hazards during the use of the grinding disc.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a grinding device, including a grinding machine, a mechanical arm fixedly connected to one side of the grinding machine, a mounting frame rotatably connected to one side of the mechanical arm, a threaded groove rod passing through one side of the mounting frame, a grinding disc threadedly connected to the inner wall of the threaded groove rod, a drive motor fixedly connected to one side of the mounting frame, the output end of the drive motor fixedly connected to one side of the threaded groove rod, a clamp fixedly connected to one side of the grinding machine, a protective device provided on the outer surface of one end of the mounting frame, the protective device including a ring block, a detachable device provided between the inner wall of the ring block and the outer surface of one end of the mounting frame, the protective device can protect the outer surface of the grinding disc during use or when not in use, and the detachable device can remove the ring block from the outer surface of one end of the mounting frame for easy replacement.

[0006] The effect achieved by the above components is as follows: When using a grinder to grind the surface of the generator injection molded parts, the ring block can be first installed on the outer surface of one end of the mounting bracket using a detachable device. Then, the generator injection molded parts are placed in the fixture on the grinder for fixation. At the same time, the corresponding grinding disc is helically installed in the inner wall of the threaded groove rod and fixed. During grinding, the drive motor can be started to drive the threaded groove rod and the grinding disc to rotate. Then, the grinder is started to drive the robotic arm to move, thereby causing the grinding disc to change the angle and position accordingly to grind the surface of the generator injection molded parts.

[0007] Preferably, one end of the mounting bracket is inserted into the inner wall of the ring block, a disc is fixedly connected to the outer surface of the ring block, a plurality of sliding holes are opened on one side of the disc, a protective rod is slidably connected to the inner wall of the sliding holes, a first spring is fixedly connected to one side of the protective rod, and one end of the first spring is fixedly connected to one side of the disc.

[0008] The effect achieved by the above-mentioned components is as follows: By setting up a protective device, during the grinding process, when the grinding disc approaches the surface of the generator injection molded part, several protective rods will slide to one end to a corresponding distance according to the shape of the generator injection molded part surface, causing the first spring to deform and stretch, covering the grinding disc while not hindering the grinding effect of the grinding disc rotation. In this way, if the operator operates during the grinding process, they will not accidentally touch the grinding disc. Similarly, when not in use, the first spring will reset, causing the protective rods to return to their original position, completely covering the grinding disc, so that when cleaning the grinding machine or fixture, the grinding disc will not be accidentally touched, reducing the probability of scratches, reducing safety hazards during use, and making the grinding machine safer during use or storage.

[0009] Preferably, a plurality of telescopic rods are fixedly connected to one side of the disc, one end of each telescopic rod is fixedly connected to one side of the slide rod, and the telescopic rod is sleeved and connected to the first spring.

[0010] The effect achieved by the above components is that by setting the telescopic rod, the inner wall of the first spring can be supported and reinforced, making it less prone to bending and damage during use, and thus increasing its service life.

[0011] Preferably, a rubber block is fixedly connected to one side of the protective rod, and the rubber block is located at the end of the protective rod away from the first spring.

[0012] The effect achieved by the above components is that by setting rubber blocks, the contact point between the protective rod and the generator injection molded part can be protected, preventing slippage at the contact point and scratching the surface of the generator injection molded part.

[0013] Preferably, the detachable device includes two locking blocks. A sliding groove is symmetrically formed on the outer surface of one end of the mounting bracket. A second spring is fixedly connected to one side of the inner wall of the sliding groove. The inner wall of the sliding groove is slidably connected to one end of the locking block. One end of the locking block is fixedly connected to one end of the second spring. A locking groove is symmetrically formed on the outer surface of the annular block. One end of the locking block is inserted into the inner wall of the locking groove.

[0014] The effect achieved by the above-mentioned components is as follows: by setting a detachable device, when it is necessary to install the replaced protective device on the mounting frame, the locking block can be pulled outward to a certain distance in the inner wall of the slide groove, causing the second spring to stretch. Then, the inner wall of the ring block is fitted onto the outer surface of one end of the mounting frame to a certain position. The locking block is released, so that under the reset action of the second spring, one end can be locked into the slot, fixing the ring block on the outer surface of one end of the mounting frame. The replaced ring block is then fixed on the mounting frame, facilitating disassembly and installation operations and making maintenance easier.

[0015] Preferably, the inner wall of the annular block is symmetrically fixedly connected with a limiting block, and a limiting groove is symmetrically opened on one side of one end of the mounting bracket, with the limiting block inserted into the inner wall of the limiting groove.

[0016] The effect achieved by the above components is as follows: by setting the limiting block and the limiting groove, when the inner wall of the ring block is fitted onto the outer surface of one end of the mounting bracket, the limiting block can be aligned with the limiting groove and locked in, thus ensuring that one end of the locking block is quickly aligned with the locking groove, which facilitates the installation of the ring block.

[0017] Preferably, one end of the card block is provided with a chamfer, and the chamfered end of the card block is located at the end of the card block away from the second spring.

[0018] The effect achieved by the above components is that by setting a chamfer at one end of the card block, the area at one end can be reduced, which facilitates the installation of the ring block and makes it easier for the card block to be inserted into the card slot.

[0019] Preferably, a pull block is fixedly connected to one side of the card block, and the longitudinal section of the pull block is L-shaped.

[0020] The effect achieved by the above components is that by setting up the pull block, the contact area on one side of the block can be increased, making it easier to manually grasp and pull one side of it.

[0021] The beneficial effects of this utility model are:

[0022] By installing a protective device, during the grinding process, when the grinding disc approaches the surface of the generator injection molded part, several protective rods will slide to one end to a corresponding distance according to the shape of the generator injection molded part surface, causing the first spring to deform and stretch, covering the grinding disc while not hindering the grinding effect of the grinding disc rotation. In this way, if the operator operates during the grinding process, they will not accidentally touch the grinding disc. Similarly, when not in use, the first spring will reset, causing the protective rods to return to their original position, completely covering the grinding disc. This prevents accidental contact with the grinding disc when cleaning the grinding machine or fixture, reducing the probability of scratches and lowering safety hazards during use, making the grinding machine safer during use or storage.

[0032] Example 1

[0033] Figure 1-5 The invention illustrates a grinding device for injection-molded generator parts, comprising a grinding machine 1, a mechanical arm 4 fixedly connected to one side of the grinding machine 1, a mounting frame 5 rotatably connected to one side of the mechanical arm 4, a threaded groove rod 6 threadedly connected to one side of the mounting frame 5, a grinding disc 7 threadedly connected to the inner wall of the threaded groove rod 6, a drive motor 8 fixedly connected to one side of the mounting frame 5, the output end of the drive motor 8 fixedly connected to one side of the threaded groove rod 6, a clamp 9 fixedly connected to one side of the grinding machine 1, a protective device 2 provided on the outer surface of one end of the mounting frame 5, the protective device 2 including a ring block 21, a detachable device 3 provided between the inner wall of the ring block 21 and the outer surface of one end of the mounting frame 5, the protective device 2 can protect the outer surface of the grinding disc 7 during use or when not in use, and the detachable device 3 can remove the ring block 21 from the outer surface of one end of the mounting frame 5 for easy replacement. When using the grinder 1 to grind the surface of the generator injection molded parts, the ring block 21 can be installed on the outer surface of one end of the mounting bracket 5 using the detachable device 3. Then, the generator injection molded parts are placed in the clamp 9 on the grinder 1 for fixation. At the same time, the corresponding grinding disc 7 is screwed into the inner wall of the threaded groove rod 6 and fixed. During grinding, the drive motor 8 can be started to drive the threaded groove rod 6 and the grinding disc 7 to rotate. Then, the grinder 1 is started to drive the robotic arm 4 to move, thereby causing the grinding disc 7 to change the angle and position accordingly to grind the surface of the generator injection molded parts.

[0034] Example 2

[0035] Figure 1-5One end of the mounting bracket 5 shown is inserted into the inner wall of the ring block 21. A disc 22 is fixedly connected to the outer surface of the ring block 21. Several sliding holes 23 are opened on one side of the disc 22. A protective rod 24 is slidably connected to the inner wall of the sliding holes 23. A first spring 25 is fixedly connected to one side of the protective rod 24. One end of the first spring 25 is fixedly connected to one side of the disc 22. During the grinding process of the grinding disc 7, when the grinding disc 7 approaches the surface of the generator injection molded part, several protective rods 24 will slide to one end to a corresponding distance in the inner wall of the sliding hole 23 according to the shape of the generator injection molded part surface. This will cause the first spring 25 to deform and stretch, covering the grinding disc 7 while not hindering the grinding effect of the grinding disc 7. In this way, if the operator operates the grinding disc 7 during the grinding process, they will not accidentally touch the grinding disc 7. Similarly, when not in use, the first spring 25 will reset the protective rods 24, completely covering the grinding disc 7. This will prevent accidental contact with the grinding disc 7 when cleaning the grinding machine 1 or the clamp 9, reducing the probability of scratches and lowering safety hazards during use. This makes the grinding machine 1 safer during use or storage.

[0036] Figure 1-5 Several telescopic rods 26 are fixedly connected to one side of the disc 22 shown. One end of each telescopic rod 26 is fixedly connected to one side of the sliding rod, and the telescopic rod 26 is sleeved and connected to the first spring 25. By setting the telescopic rods 26, the inner wall of the first spring 25 can be supported and reinforced, making it less prone to bending damage during use and improving its service life. A rubber block 27 is fixedly connected to one side of the protective rod 24, and the rubber block 27 is located at the end of the protective rod 24 away from the first spring 25. By setting the rubber block 27, the contact point between the protective rod 24 and the generator injection molded part can be protected, preventing slippage at the contact point and scratching the surface of the generator injection molded part.

[0037] Example 3

[0038] Figure 1-5The detachable device 3 shown includes two locking blocks 33. A sliding groove 31 is symmetrically opened on the outer surface of one end of the mounting bracket 5. A second spring 32 is fixedly connected to one side of the inner wall of the sliding groove 31. The inner wall of the sliding groove 31 is slidably connected to one end of the locking block 33. One end of the locking block 33 is fixedly connected to one end of the second spring 32. A locking groove 34 is symmetrically opened on the outer surface of the ring block 21. One end of the locking block 33 is inserted into the inner wall of the locking groove 34. When the replaced protective device 2 needs to be installed on the mounting bracket 5, the locking block 33 can be pulled outward in the inner wall of the slide groove 31 to a certain distance, causing the second spring 32 to be stretched. Then, the inner wall of the ring block 21 is fitted onto the outer surface of one end of the mounting bracket 5 to a certain position. The locking block 33 is released, so that under the reset action of the second spring 32, one end can be inserted into the locking groove 34, fixing the ring block 21 on the outer surface of one end of the mounting bracket 5. The replaced ring block 21 is then fixed on the mounting bracket 5, making it convenient for disassembly and installation operations and for maintenance.

[0039] Figure 1-5 The inner wall of the circular block 21 shown is symmetrically fixedly connected with limiting blocks 35. One end of the mounting bracket 5 has symmetrically formed limiting grooves 36, and the limiting blocks 35 are inserted into the inner wall of the limiting grooves 36. By setting the limiting blocks 35 and limiting grooves 36, when the inner wall of the circular block 21 is fitted onto the outer surface of one end of the mounting bracket 5, the limiting blocks 35 can be aligned with the limiting grooves 36 and engaged. This ensures that one end of the locking block 33 quickly aligns with the locking slot 34, facilitating the installation of the circular block 21. One end of the locking block 33 has a chamfer, and this chamfered end is located at the end of the locking block 33 furthest from the second spring 32. By chamfering one end of the locking block 33, the area at one end can be reduced, facilitating the installation of the circular block 21 and making it easier for the locking block 33 to engage with the locking slot 34. A pull block 37 is fixedly connected to one side of the locking block 33, and the longitudinal section of the pull block 37 is L-shaped. By setting the pull block 37, the contact area on one side of the locking block 33 can be increased, making it easier to manually grasp and pull one side of it.

[0040] Working Principle: When using the grinder 1 to grind the surface of the generator injection molded part, the locking block 33 can be pulled outward in the inner wall of the slide groove 31 to a certain distance, causing the second spring 32 to stretch. Then, the inner wall of the ring block 21 is fitted onto the outer surface of one end of the mounting bracket 5 to a certain position. The locking block 33 is released, allowing one end to be locked into the locking groove 34 under the reset action of the second spring 32, fixing the ring block 21 to the outer surface of one end of the mounting bracket 5. The generator injection molded part is then placed in the clamp 9 on the grinder 1 for fixation. At the same time, the corresponding grinding disc 7 is spirally installed in the inner wall of the threaded groove rod 6 and fixed. During grinding, the drive motor 8 can be started to drive the threaded groove rod 6 and the grinding disc 7 to rotate. Then, the grinder 1 is started to drive the robotic arm 4 to move, thereby driving the grinding disc 7 to rotate. The surface of the generator injection molded parts is ground according to changes in angle and position. During the grinding process of the grinding disc 7, when the grinding disc 7 approaches the surface of the generator injection molded parts, several protective rods 24 will slide to one end to a corresponding distance in the inner wall of the sliding hole 23 according to the shape of the surface of the generator injection molded parts. This will cause the first spring 25 to deform and stretch, covering the grinding disc 7 while not hindering the grinding effect of the grinding disc 7. In this way, if the operator operates during the grinding process, he will not accidentally touch the grinding disc 7. Similarly, when not in use, the first spring 25 will reset the protective rods 24, completely covering the grinding disc 7. This will prevent accidental contact with the grinding disc 7 when cleaning the grinding machine 1 or the clamp 9, reducing the probability of scratches and lowering the safety hazards during use, making the grinding machine 1 safer during use or storage.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
