Technical Field
[0001] This utility model relates to the field of grinding equipment, and in particular to an abrasive clamping device and a quick-change grinding system. Background Technology
[0002] In traditional grinding operations, the clamping and replacement of abrasives mainly rely on manual operation or simple fixed fixtures, which have significant problems such as low efficiency, poor compatibility, insufficient stability and automation bottlenecks. Specifically, the time spent on manual loading and unloading is difficult to match the pace of automated production lines, and fixed fixtures are difficult to adapt to different specifications of abrasives and are cumbersome to replace. These problems are particularly prominent in scenarios where abrasives need to be changed frequently in multiple processes, which seriously restricts the improvement of production efficiency and automation. Utility Model Content
[0003] The purpose of this invention is to provide an abrasive clamping device and a quick-change grinding system to solve the problem of low abrasive replacement efficiency in the prior art.
[0004] The technical solution of this utility model is: an abrasive clamping device, including a body, on which a clamping fixture is installed in the horizontal direction; multiple clamping fixtures are provided on the body, and any clamping fixture has an L-shaped projection on the vertical plane, including an installation end arranged in the vertical direction and a clamping part opened in the horizontal direction; the installation end is fixed to the body, and the clamping part can be clamped in the horizontal direction with a pre-set clamped part on the abrasive, restricting the movement of the abrasive in the vertical direction, and the clamping part has at least one open end for the abrasive to be picked up and put in the horizontal direction.
[0005] Preferably, the snap-fit fixture is equipped with an elastic element, one end of which is set as a fixed end and fixed to the snap-fit fixture, and the other end is set as an abutting end and abuts against the abrasive; the abutting end applies a spring force in the vertical direction to the abrasive, so that the snapped part of the abrasive is tightly engaged with the snapping part of the snap-fit fixture.
[0006] Preferably, the mounting end has a waist-shaped hole, and a fastener is provided in conjunction with the waist-shaped hole. The fastener passes through the waist-shaped hole and is threaded into the body to fix the clamping fixture to the body.
[0007] Preferably, the body is configured as a stepped structure, having at least two vertical mounting surfaces and a platform perpendicular to the mounting surfaces. Threaded holes are provided on any of the mounting surfaces, and multiple sets of threaded holes are provided along the vertical direction. The fasteners pass through the waist-shaped holes and mate with different threaded holes, so that the clamping fixture has different spacing from the platform.
[0008] A quick-change grinding system employs an abrasive clamping device, including a robotic arm. The robotic arm's execution end is equipped with a quick-change interface, and the top of the abrasive is equipped with a quick-change plug. The quick-change interface and the quick-change plug can be engaged vertically.
[0009] Preferably, it includes a feeding rack, which is fixed to the main body and has a feeding trough. The feeding trough has at least one open end for the robotic arm to carry abrasive material in and out. The feeding rack can abut against the top of the abrasive material entering the feeding trough and separate the quick-change plug from the quick-change interface as the robotic arm lifts.
[0010] Preferably, the unloading rack is connected to the main body via an anti-jamming mechanism. The anti-jamming mechanism includes an anti-jamming slide rail fixed vertically to the main body. The unloading rack is slidably connected to the anti-jamming slide rail. Under the action of the anti-jamming spring, the unloading rack tends to the lowest end of the anti-jamming slide rail. An anti-jamming switch is provided in the middle or top of the anti-jamming slide rail. When the unloading rack compresses the anti-jamming spring and runs to the trigger end of the anti-jamming switch, the robotic arm stops moving and triggers the alarm.
[0011] Preferably, the body is provided with a first detector, which is located at the top of the stepped structure of the body and is used to detect the presence or absence of abrasive on the robotic arm.
[0012] Preferably, a second detector is installed in the main body. The second detector is set for any snap-fit fixture. The detection end of the second detector can detect the presence or absence of abrasive on the snap-fit fixture through a detection hole opened on the main body adjacent to the snap-fit fixture.
[0013] Compared with the prior art, the advantages of this utility model are:
[0014] (1) This solution achieves rapid loading and unloading of abrasives by using the horizontal open end design of the clamping fixture and the horizontal clamping of the abrasive ring groove, combined with the quick-change interface of the robotic arm and the setting of the unloading rack. The first detector at the top of the main body monitors the abrasive status in real time, ensuring operational safety and significantly improving the abrasive clamping efficiency and automation level.
[0015] (2) The elastic element continuously applies vertical elastic force to ensure that the abrasive is tightly fitted with the clamping part, thereby enhancing the clamping stability.
[0016] (3) An anti-jamming mechanism is provided to alarm when the abrasive and the robotic arm get stuck and cannot be fed, so as to avoid damage to the equipment when forcibly feeding. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to specific embodiments:
[0025] like Figure 1 and Figure 2 As shown, an abrasive clamping device 200 is used for the rapid loading and unloading of abrasive 100. It includes a body 1, on which a clamping fixture 2 is mounted horizontally. Multiple clamping fixtures 2 are provided on the body 1, each formed by bending sheet metal, and have an L-shaped projection on a vertical plane. Each fixture includes a mounting end 21 positioned vertically and a clamping portion 22 opened horizontally. The mounting end 21 is fixed to the body 1, and the clamping portion 22 can clamp horizontally with a pre-set clamping portion 22 on the abrasive 100, restricting the movement of the film material in the vertical direction. Furthermore, the clamping portion 22 has an open end for loading and unloading the film material horizontally. In this embodiment, the clamping portion 22 on the abrasive 100 is configured as an annular groove with a vertical axis, and the clamping portion 22 is embedded horizontally into the annular groove.
[0026] In addition, an elastic element 23 is installed on the snap-fit fixture 2. One end of the elastic element 23 is set as a fixed end and fixed on the snap-fit fixture 2, and the other end is set as an abutting end and passes through the preset hole on the snap-fit fixture 2 to abut against the abrasive 100. The abutting end applies a spring force in the vertical direction to the abrasive 100, so that the snapped part 22 of the abrasive 100 and the snapped part 22 on the snap-fit fixture 2 are tightly engaged.
[0027] The mounting end 21 has a waist-shaped hole, and a fastener is installed in the waist-shaped hole. The fastener passes through the waist-shaped hole and is threaded into the body 1 to fix the clamping fixture 2 to the body 1.
[0028] Furthermore, the body 1 is configured as a stepped structure. In this embodiment, it has two vertical mounting surfaces 11 and a platform 12 perpendicular to the mounting surfaces 11. Threaded holes 13 are provided on any mounting surface 11, and multiple sets of threaded holes 13 are arranged vertically. Fasteners pass through the waist-shaped holes and cooperate with different threaded holes 13, so that the clamping fixture 2 has different spacing from the platform 12, thereby adapting to the clamping work of abrasives 100 of different specifications.
[0029] Combination Figure 3 and Figure 4 As shown, this application also provides a quick-change grinding system, including the aforementioned abrasive clamping device 200 and a robotic arm 3. The robotic arm 3 has a quick-change interface 4 at its execution end, and a quick-change plug 5 at the top of the abrasive 100. The quick-change interface 4 and the quick-change plug 5 can be engaged vertically, connecting the abrasive 100 to the robotic arm 3. Specifically, the quick-change plug 5 has a locking groove 51 along its own axis, and the inner wall of the quick-change interface 4 has an elastic buckle 41 corresponding to the locking groove 51. The elastic buckle 41 engages with the locking groove 51, limiting the axial displacement of the quick-change plug 5 and the quick-change interface 4.
[0030] In addition, a feeding rack 6 is included. The feeding rack 6 is fixed to one side of the main body 1 and has a feeding groove 61. The end of the feeding groove 61 away from the main body 1 has an open end for the robotic arm 3 to carry the abrasive 100 in and out. When the robotic arm 3 carries the abrasive 100 into the feeding groove 61, the feeding rack 6 can abut against the top of the abrasive 100. At this time, the robotic arm 3 is raised. Because the top of the abrasive 100 abuts against the feeding rack 6, the quick-change plug 5 can be separated from the quick-change interface 4, so that the abrasive 100 can be detached from the robotic arm 3, allowing the robotic arm 3 to install new abrasive 100 from the main body 1.
[0031] When installing a new abrasive 100, the robotic arm 3 moves above the corresponding abrasive 100 and moves downwards to connect the quick-change plug 5 and quick-change interface 4. Then, it carries the abrasive 100 and moves horizontally toward the open end of the clamping fixture 2 until the abrasive 100 is completely separated from the clamping fixture 2. Then, it can carry the newly replaced abrasive 100 for subsequent grinding operations.
[0032] Furthermore, such as Figure 5 As shown, the unloading rack 6 is connected to the main body 1 through the anti-jamming mechanism 8, which is used to alarm when the abrasive 100 and the robotic arm 3 get stuck and cannot be unloaded, so as to avoid damaging the equipment when forcibly unloading.
[0033] The anti-jamming mechanism 8 includes an anti-jamming slide rail 82 fixed vertically to the outer wall of the main body 1. The unloading frame 6 is slidably connected to the anti-jamming slide rail 82. A slot is provided on the main body 1 for one end of the unloading frame 6 to extend into the main body 1. An anti-jamming spring 81 is installed on the inner wall of the main body 1, causing the unloading frame 6 to tend towards the lowest end of the anti-jamming slide rail 82 under the action of the anti-jamming spring 81. An anti-jamming switch 83 is provided in the middle or at the top of the anti-jamming slide rail 82. When there is no jamming between the robotic arm 3 and the abrasive 100 to be unloaded, the unloading frame 6 will compress the anti-jamming spring 81 during unloading, and will travel a small stroke, meaning that the unloading frame 6 will not trigger the trigger end of the anti-jamming switch 83. If jamming occurs, the unloading frame 6 will continue to compress the anti-jamming spring 81 until it reaches the trigger end of the anti-jamming switch 83. At this time, the robotic arm 3 will stop moving and the alarm will be triggered.
[0034] In addition, a first detector 7 is provided on the main body 1. The first detector 7 is located at the top of the stepped structure of the main body 1 and is used to detect the presence or absence of abrasive 100 on the robotic arm 3. A second detector is installed inside the main body 1. The second detector is set for any snap-fit fixture 2. The detection end of the second detector can detect the presence or absence of abrasive 100 on the snap-fit fixture through the detection hole 9 opened on the main body 1 adjacent to the snap-fit fixture 2.
