Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinding device for rigging processing. Background Technique

[0002] Rigging refers to the equipment used in conjunction with ropes and cables, such as hooks, tensioners, cable clamps, thimbles, shackles, chain links, etc., collectively referred to as rigging. Some also classify ropes and cables as rigging. Rigging mainly includes two categories: metal rigging and synthetic fiber rigging. Among them, metal rigging such as chain links need to be surface-ground and polished during the production process to remove burrs and protrusions, facilitating subsequent electroplating operations.

[0003] In the current rigging chain link processing workshop, a belt sander is mostly used for grinding. The motor drives the sand belt to rotate at high speed. The operator presses the chain link against the sand belt, and the high-speed rotating sand belt grinds the surface of the chain link at high speed to remove burrs, rust and protrusions on its surface. However, there are some functional deficiencies in the actual use process, and there is room for improvement. For example, most of the belt sanders used for chain link grinding on the market currently use a motor to drive a driving wheel to rotate at high speed, and the driving wheel then drives the sand belt to rotate at high speed. The position of the driving wheel is fixed, so the position of the sand belt is also fixed. The grinding force completely depends on the pressing force of the operator, which requires high experience of the operator. When the pressing force is too large, it is easy to cause excessive grinding, and the grinding effect will show obvious deviation, and it does not have the function of self-adjusting the grinding force.

[0004] Now, a new type of grinding device for rigging processing is proposed to solve the above problems. Content of the Utility Model

[0011] Preferably, a front fixing plate is welded to the front end of the left side of the swing frame. A reduction motor is installed on the right side of the rear end of the front fixing plate. A first clamping block is movably connected to the left side of the rear end of the front fixing plate. A transmission belt pulley is arranged between the output end of the reduction motor and the front end of the first clamping block.

[0014] Preferably, the fifth electric cylinder and the sixth electric cylinder are respectively movably connected to the swing frame, and the swing frame can swing on the top of the concave support table.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The grinding device for rigging processing not only realizes the function of self-adjusting the grinding force, but also realizes the function of adjustable grinding position, and also realizes the function of grinding the inclined side.

At this time, the third electric cylinder extends, pushing the slider to displace along the slide rail, so that the chain link is close to the sand belt for rapid grinding. During the grinding process, the reduction motor drives the first clamping block to rotate uniformly through the transmission belt pulley, and the chain link rotates synchronously. While the chain link rotates, the third electric cylinder retracts or extends uniformly, so that the chain link and the sand belt can always be kept in a fitting state, realizing the function of adjustable grinding position;

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1: Please refer to Figures 1-4 , a grinding device for rigging processing, including a main housing 1. A sand belt protection plate 2 is hinged to the left side of the front end of the main housing 1. Two groups of driving motors 3 are installed at the front end inside the main housing 1. The output end of the driving motor 3 is fixedly connected to a sand belt driving wheel 4. A loading platform 12 is fixedly connected to the right side of the main housing 1. Two groups of slide rails 13 are horizontally fixedly connected to the top of the loading platform 12. A slide block 15 is horizontally placed on the top of the slide rail 13. A third electric cylinder 14 is installed at the middle position on the right side of the loading platform 12. The top of the slide block 15 is fixedly connected to a support frame 16. The top of the support frame 16 is welded with a concave support platform 17. A swing frame 18 is movably connected to the bottom end inside the concave support platform 17. A guiding component for adjusting the grinding force is provided at the front end of the main housing 1;

[0026] Please refer to Figures 1-4 , a grinding device for rigging processing further includes a guiding component. The guiding component includes an electric cylinder fixing plate 6. The electric cylinder fixing plate 6 is welded to the right side of the front end of the main housing 1. A first electric cylinder 7 is installed on the left side of the electric cylinder fixing plate 6. A second electric cylinder 8 is installed on the right side of the electric cylinder fixing plate 6. Concave clamps 10 are respectively provided at the output ends of the first electric cylinder 7 and the second electric cylinder 8. A sand belt driven wheel 11 is movably connected inside the concave clamp 10. A pressure sensor 9 is installed on the right side of the second electric cylinder 8. A grinding sand belt 5 is sleeved outside the sand belt driving wheel 4 and the sand belt driven wheel 11;

[0027] The horizontal center lines of the electric cylinder fixing plate 6, the first electric cylinder 7, and the second electric cylinder 8 coincide. The sizes of the sand belt driving wheel 4 and the sand belt driven wheel 11 are the same. The pressure sensor 9 and the concave clamp 10 are connected. The first electric cylinder 7, the second electric cylinder 8, and the pressure sensor 9 are electrically connected. The left side of the third electric cylinder 14 is connected to the right side of the slider 15. The slider 15 can slide left and right along the top of the slide rail 13, and can adjust the grinding force by itself to avoid over-grinding.

[0028] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, the sand belt driving wheel 4 drives the grinding sand belt 5 to rotate at high speed. The chain link can be ground by the sand belt on its outside when it is close to the sand belt driven wheel 11, removing burrs and rust on the surface. During grinding, the chain link will exert a certain pressure on the sand belt driven wheel 11, and the pressure is feedback to the pressure sensor 9 through the concave clamp 10. When the pressure is higher than the preset threshold, it means that the pressing force is too large. The second electric cylinder 8 retracts slightly, and the first electric cylinder 7 extends synchronously and slightly, retracting the sand belt driven wheel 11 by a certain distance to protect the grinding chain link.

[0029] Embodiment 2: The front end of the left side of the swing frame 18 is welded with a front fixing plate 19. A reduction motor 20 is installed on the right side of the rear end of the front fixing plate 19. The left side of the rear end of the front fixing plate 19 is movably connected with a first clamping block 21. A transmission belt pulley 22 is arranged between the output end of the reduction motor 20 and the front end of the first clamping block 21. The rear end of the left side of the swing frame 18 is welded with a rear fixing plate 23. Two groups of fourth electric cylinders 24 are installed on the left side of the rear end of the rear fixing plate 23. The front end of the fourth electric cylinder 24 is fixedly connected with a push plate 25. The left side of the front end of the push plate 25 is movably connected with a second clamping block 26. The shapes and sizes of the first clamping block 21 and the second clamping block 26 are the same. The transmission belt pulley 22 can drive the first clamping block 21 to rotate, facilitating the rotation of the chain link to change the grinding position.

[0030] Specifically, as Figure 3 and Figure 4 shown, the chain link is placed between the first clamping block 21 and the second clamping block 26. When the fourth electric cylinder 24 extends forward, the push plate 25 will push the second clamping block 26 and the first clamping block 21 to close, and the chain link will be firmly clamped. At this time, the third electric cylinder 14 extends, pushing the slider 15 to displace along the slide rail 13, making the chain link close to the sand belt, and rapid grinding can be carried out. During the grinding process, the reduction motor 20 drives the first clamping block 21 to rotate at a constant speed through the transmission belt pulley 22, and the chain link rotates synchronously.

[0031] Embodiment 3: A fifth electric cylinder 27 is movably connected to the front end inside the concave platform 17, and a sixth electric cylinder 28 is movably connected to the rear end inside the concave platform 17. The fifth electric cylinder 27 and the sixth electric cylinder 28 are respectively movably connected to the swing frame 18. The swing frame 18 can swing on the top of the concave platform 17 and can polish the inclined side of the chain link by swinging.

[0032] Specifically, as Figure 1 and Figure 4 shown, when the fifth electric cylinder 27 extends and the sixth electric cylinder 28 retracts, the right side of the swing frame 18 moves backward and the left side moves forward, so that the inclined side of the rear end of the chain link can be polished. When the fifth electric cylinder 27 retracts and the sixth electric cylinder 28 extends, the right side of the swing frame 18 moves forward and the left side moves backward, so that the inclined side of the front end of the chain link can be polished.

[0033] Working principle: When the present utility model is in use, first, place the chain link between the first clamping block 21 and the second clamping block 26. The fourth electric cylinder 24 extends forward, and the push plate 25 pushes the second clamping block 26 and the first clamping block 21 to close, and the chain link is firmly clamped. At this time, the third electric cylinder 14 extends, pushing the slider 15 to displace along the slide rail 13, so that the chain link is close to the abrasive belt, and rapid polishing can be carried out. During the polishing process, the deceleration motor 20 drives the first clamping block 21 to rotate at a constant speed through the transmission belt pulley 22, and the chain link also rotates synchronously. While the chain link rotates, the third electric cylinder 14 retracts or extends at a constant speed, so that the chain link and the abrasive belt can always be kept in a fitting state. As the chain link is fixed, the driving motor 3 drives the abrasive belt driving wheel 4 to rotate at a high speed, and the abrasive belt driving wheel 4 drives the polishing abrasive belt 5 to rotate at a high speed. The chain link close to the abrasive belt driven wheel 11 can be polished by the abrasive belt on its outside to remove burrs and rust on the surface. During polishing, the chain link will exert a certain pressure on the abrasive belt driven wheel 11, and the pressure is transmitted to the pressure sensor 9 through the concave clamp 10. When the pressure is higher than the preset threshold, it means that the pressing force is too large. The second electric cylinder 8 retracts slightly, and the first electric cylinder 7 extends slightly synchronously, withdrawing the abrasive belt driven wheel 11 by a certain distance to protect the polished chain link and reduce the probability of over-polishing. When it is necessary to polish the inclined side of the chain link, the fifth electric cylinder 27 extends and the sixth electric cylinder 28 retracts, then the right side of the swing frame 18 moves backward and the left side moves forward, so that the inclined side of the rear end of the chain link can be polished. When the fifth electric cylinder 27 retracts and the sixth electric cylinder 28 extends, the right side of the swing frame 18 moves forward and the left side moves backward, so that the inclined side of the front end of the chain link can be polished.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
