Description
Technical Field
[0001] This utility model relates to the technical field of robotic arm fixing devices, specifically a robotic arm fixing device for operation. Background Technology
[0002] Robotic arms are core technology equipment in the field of industrial automation. Their core function is to perform high-precision tasks such as grasping, handling, assembly, and welding in three-dimensional space by simulating the movement capabilities of the human arm. Robotic arms have been widely used in automobile manufacturing, electronics manufacturing, medical, aerospace and service industries, becoming an indispensable part of modern development.
[0003] Existing robotic arms require specific fixing devices to ensure stability during use. These devices are typically located at the bottom of the arm, allowing it to be fixed to the ground. To facilitate movement, some devices also include casters or other movable structures at the bottom. However, due to the arm's height, the center of gravity is prone to shifting during movement, increasing the risk of accidents. Therefore, a new robotic arm fixing device is urgently needed to solve these problems. Utility Model Content
[0004] The purpose of this utility model is to provide a fixing device for a robotic arm to solve the problem mentioned in the background art, which is that the center of gravity is prone to deviate during movement due to the height of the robotic arm, thus increasing the danger of use.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a working robot arm fixing device, including a base plate, wherein two fixing plates are fixedly connected to the upper surface of the base plate, and a fixing base for supporting and fixing the robot arm is provided between the two fixing plates.
[0006] A tilting mechanism is provided above the fixed plate, and the tilting mechanism is located on one side of the fixed base to adjust the tilt angle of the fixed base.
[0007] The fixed plate is internally slidably connected to a sliding plate, and the upper surface of the sliding plate is provided with two support mechanisms;
[0008] Both the base plate and the sliding plate are fixedly equipped with casters on their lower surfaces to facilitate overall movement.
[0009] The inner wall of the base plate has two mounting plates that are slidably connected. The mounting plates are U-shaped and have multiple threaded holes at the bottom.
[0010] The inner wall of the base plate is threaded with two fixing rods, and the upper end of the fixing rods is inserted into the inner wall of the fixed base.
[0011] The tilting mechanism includes a support plate, the lower surface of which is fixedly connected to a fixed plate. A rotating shaft is rotatably connected to the inner wall of the support plate. One end of the rotating shaft is fixedly connected to a fixed base, and the other end of the rotating shaft is fixedly connected to a gear.
[0012] The outer surface of the gear is meshed with a toothed plate, and a hydraulic rod is fixedly installed on the upper surface of the fixed plate. The telescopic shaft of the hydraulic rod is fixedly connected to one end of the toothed plate.
[0013] The support mechanism includes a fixed block, the lower surface of which is fixedly connected to a sliding plate, and a support rod hinged to the inner wall of the fixed block, the outer surface of which is slidably connected to the inner wall of the fixed plate.
[0014] The inner wall of the fixing block is threaded with a fixing bolt, and the outer surface of the fixing bolt is also slidably connected to the support rod. The end of the support rod is provided with an elastic band when the device moves.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The present invention relates to a robotic arm fixing device. When a position needs to be moved, the sliding plate is pulled to move outward of the fixing plate, and the two support mechanisms are erected and fixed. The tilting mechanism drives the fixed base to rotate, thereby tilting the robotic arm on it. The support mechanism supports the upper part of the robotic arm, keeping the robotic arm in a horizontal or near-horizontal state, thereby reducing the height of the robotic arm's center of gravity and increasing safety during movement. This solves the problem that existing robotic arms, due to their height, are prone to center of gravity deviation during movement, increasing the risk of use.
[0017] 2. This utility model discloses a robotic arm fixing device. A hydraulic rod extends, causing a gear plate to move horizontally, which in turn rotates the gear. The gear then rotates the fixed base, causing the robotic arm to tilt towards the sliding plate. An elastic band provides cushioning and support to the upper part of the robotic arm, preventing accidental rapid falls and reducing damage. When the robotic arm moves above the sliding plate, the elastic band also isolates the sliding plate from the robotic arm, protecting it from scratches. The sliding plate primarily supports the robotic arm, while the elastic band provides auxiliary support, thus achieving the goal of supporting the upper part of the robotic arm.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 This utility model provides a robotic arm fixing device, including a base plate 1, two fixing plates 2 fixedly connected to the upper surface of the base plate 1, and a fixing base 3 for supporting and fixing the robotic arm between the two fixing plates 2; an tilting mechanism 4 is provided above the fixing plates 2, and the tilting mechanism 4 is located on one side of the fixing base 3 to adjust the tilt angle of the fixing base 3; a sliding plate 5 is slidably connected inside the fixing plate 2, and two support mechanisms 6 are provided on the upper surface of the sliding plate 5; universal wheels 7 are fixedly installed on the lower surfaces of the base plate 1 and the sliding plate 5 to facilitate overall movement.
[0026] Two fixed plates 2 are located on either side of the middle of the base plate 1. Each fixed plate 2 has an inclined mechanism 4 on its upper part, which can be used to support the two inclined mechanisms 4. The two inclined mechanisms 4 are located on both sides of the fixed base 3, which are used to support the fixed base 3 and adjust the inclined angle of the fixed base 3. The fixed base 3 has at least four threaded holes for mounting with the robotic arm, thereby supporting the lower part of the robotic arm. The sliding plate 5 is U-shaped, and its two ends and the position near the two ends are inserted into the interior of the sliding plate 5, allowing it to slide with the sliding plate 5. Its support mechanism 6 is also located inside the fixed plate 2. The interior of the fixed plate 2 has a T-shaped groove for placing the sliding plate 5 and the support mechanism 6. There are four casters 7 at the bottom of the base plate 1 and two casters 7 at the bottom of the sliding plate 5. The lower parts of the six casters 7 are flush to achieve smooth movement. The outer surface of the sliding plate 5 is provided with a round shaft, and the inner wall of the fixed plate 2 has a corresponding groove to prevent the sliding plate 5 from being completely pulled out inside the fixed plate 2. This is a commonly used limiting method in the prior art.
[0027] Two mounting plates 8 are slidably connected to the inner wall of the base plate 1. The mounting plates 8 are U-shaped and have multiple threaded holes at the bottom. The mounting plates 8 are used to fix the whole. When the device is moved to a suitable position, the mounting plates 8 can be fixed to the lower bearing surface by bolts. After being fixed, the base plate 1 is supported by casters 7 to prevent the base plate 1 from moving downward. The mounting plates 8 fix the position of the base plate 1 to prevent the base plate 1 from moving upward and horizontally. When it is necessary to move the device, the mounting plates 8 can be removed to allow it to slide upward.
[0028] The inner wall of the base plate 1 is threaded with two fixing rods 9. The upper end of the fixing rod 9 is inserted into the inner wall of the fixed base 3. By rotating the fixing rod 9, the fixing rod 9 can move up or down. After the fixing rod 9 is inserted into the interior of the fixed base 3, it can fix the fixed base 3 to prevent the fixed base 3 from tilting when using the robotic arm and increase stability. When the fixing rod 9 is pulled out from inside the fixed base 3, it releases the restriction on the fixed base 3 so that the fixed base 3 can tilt.
[0029] The tilting mechanism 4 includes a support plate 401, the lower surface of which is fixedly connected to the fixed plate 2. A rotating shaft 402 is rotatably connected to the inner wall of the support plate 401. One end of the rotating shaft 402 is fixedly connected to the fixed base 3, and the other end of the rotating shaft 402 is fixedly connected to a gear 403. The rotating shaft 402 is limited by the support plate 401, and the rotating shaft 402 supports the fixed base 3, thereby supporting the upper robotic arm. At the same time, the fixed base 3 and the upper robotic arm can rotate around the center of the rotating shaft 402.
[0030] The outer surface of the gear 403 is meshed with a toothed plate 404. A hydraulic rod 405 is fixedly installed on the upper surface of the fixed plate 2. The telescopic shaft of the hydraulic rod 405 is fixedly connected to one end of the toothed plate 404. The upper part of the toothed plate 404 is provided with teeth, and the outer surface of the gear 403 is provided with teeth. When meshed, when the toothed plate 404 moves horizontally, it can drive the gear 403 to rotate. A square plate is fixedly connected to the end of the toothed plate 404 so that the hydraulic rod 405 can hold it in place and drive the toothed plate 404 to move horizontally.
[0031] The support mechanism 6 includes a fixed block 601, the lower surface of which is fixedly connected to the sliding plate 5. A support rod 602 is hinged to the inner wall of the fixed block 601. The outer surface of the support rod 602 is slidably connected to the inner wall of the fixed plate 2. The support rod 602 can rotate at the fixed block 601. When the robotic arm is in use, the support rod 602 is in a horizontal state and located inside the fixed plate 2. When moving, the support rod 602 slides out of the fixed plate 2 and is adjusted to a horizontal state.
[0032] The inner wall of the fixed block 601 is threaded with a fixing bolt 603. The outer surface of the fixing bolt 603 is also slidably connected to the support rod 602. The end of the support rod 602 is provided with an elastic band 604 when the device moves. The support rod 602 has a threaded hole. When the support rod 602 is kept vertical, it can be fixed to the fixed block 601 by the fixing bolt 603. The elastic band 604 has a certain elasticity, which can buffer and support the robot arm when it falls, and at the same time isolate the robot arm from the sliding plate 5 to prevent the robot arm from contacting hard parts and to prevent damage.
[0033] Working principle: When a position needs to be moved, pull the sliding plate 5, which moves outward from the fixed plate 2, erecting and fixing the two support mechanisms 6. Tighten the fixed rod 9 to release the restriction on the fixed base 3. The tilting mechanism 4 drives the fixed base 3 to rotate, thereby tilting the robotic arm on it. Specifically, the hydraulic rod 405 extends, driving the gear plate 404 to move horizontally, thereby rotating the gear 403. The gear 403 drives the fixed base 3 to rotate, thereby tilting the robotic arm towards the position of the sliding plate 5. The support mechanism 6 supports the upper part of the robotic arm. Specifically, the elastic band 604 provides cushioning support for the upper part of the robotic arm, preventing the robotic arm from falling rapidly and reducing damage. When the robotic arm moves above the sliding plate 5, the elastic band 604 also isolates the sliding plate 5 from the robotic arm, keeping the robotic arm in a horizontal or near-horizontal state to lower the height of the robotic arm's center of gravity. Then, release the fixing of the mounting plate 8 to the ground to facilitate movement.
