Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to a robot swing arm core coating suspension device. Background Technology

[0002] Pump casing cores are the core components used in the casting process to form the complex flow channels and cavities inside the pump body. Core solutions can be customized according to the pump body structure (such as the wear resistance requirements of dredging pumps).

[0003] Pump casing cores often contain deep cavities, narrow slits, or blade-separated flow channels (such as 10mm narrow flow channels or multi-layer volute structures), which are difficult to cover evenly with traditional brushing or spraying. Therefore, flow coating is used to apply the corresponding coating to its surface.

[0004] During the flow coating process of the pump housing core, it is necessary to lift the pump housing core. The existing suspension device is generally a robotic arm. The hook of the robotic arm is connected to multiple chains. The bottom of the chains is connected to the connector of the pump housing core through hooks, thereby lifting the pump housing core. However, this method has problems in actual operation. Due to the deviation in the position of the connector fixed to the pump housing core, and the error in the connection between the chain and the hook of the robotic arm, not all chains are in a taut state when lifting the pump housing core. If the chains are not taut, they cannot apply force to the pump housing core, which will lead to poor stability of the pump housing core after lifting, and the angle is prone to deviation. Especially when only two chains are taut, the angle deviation of the pump housing core after lifting is larger, making it difficult to guarantee the flow coating quality. Utility Model Content

[0005] The main purpose of this utility model is to provide a robot swing arm core coating suspension device. The overall length of the cylinder, the second screw, the connecting hook, the first screw and the chain is adjustable, so as to ensure that each chain is in a taut state when lifting the pump housing core, thereby avoiding a large deviation between the angle of the pump housing core and the preset angle after lifting, so as to ensure the coating quality.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A robotic arm suspension device for core coating includes a robotic arm and a crossbeam. A lifting ring is provided on the crossbeam, and a hook of the robotic arm is connected to the lifting ring. Several fixing devices are provided on the crossbeam, and several chains are connected to the fixing devices. A first screw is connected to the bottom of the chain. The device also includes a cylinder with internal threads. One end of the first screw is threaded to the cylinder, and the other end of the cylinder is threaded to a screw hook.

[0008] Furthermore, the screw hook includes a second screw threadedly connected to the cylinder body, and a connecting hook is welded to one end of the second screw.

[0009] Furthermore, the fixing device includes a fixing plate fixedly connected to the crossbeam, the fixing plate having a through hole, a connecting ring being connected to the fixing plate through the through hole, and one end of the chain being connected to the connecting ring.

[0010] Furthermore, a connecting hole is provided at the end of the first screw located outside the cylinder, and one end of the chain is fixedly connected to the first screw through the connecting hole.

[0011] Furthermore, the lifting ring is located at the center of the crossbeam.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The overall length of the cylinder, second screw, connecting hook, first screw and chain of this utility model is adjustable, so as to ensure that each chain is in a taut state when the pump housing core is lifted, thereby avoiding a large deviation between the angle of the pump housing core and the preset angle after lifting, so as to ensure the quality of the flow coating.

[0014] The second screw of this invention can rotate, so that the connecting hook connects with the connecting part of the pump housing core at a suitable angle. Then the second screw is no longer rotated, and the tension of the chain is ensured by rotating the first screw.

[0015] The connecting ring of this invention has a large range of motion within the through hole. Therefore, when the chain is connected to the connecting ring, the adjustable angle at the upper end of the chain is large, so that the connecting hook at the lower end of the chain has a large range of motion.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-3 As shown, a robot swing arm core coating suspension device includes a robot swing arm 1 and a crossbeam 3. A lifting ring 2 is provided on the crossbeam 3. The hook of the robot swing arm 1 is connected to the lifting ring 2. Several fixing devices 4 are provided on the crossbeam 3. Several chains 5 are connected to the fixing devices 4. A first screw 8 is connected to the bottom of the chain 5. The device also includes a cylinder 6 with internal threads. One end of the first screw 8 is threaded to the cylinder 6, and the other end of the cylinder 6 is threaded to a screw hook 7. The lifting ring 2 is located at the center of the crossbeam 3.

[0022] In this embodiment, two sets of fixing devices 4 are provided, located at both ends of the crossbeam 3 respectively. At least two chains 5 are connected to the two fixing devices 4. When suspending the pump housing core, the hook of the robot arm 1 should be connected to the lifting ring 2 first. Then, according to the position of the pump housing core connector, the length of each first screw 8 and screw hook 7 screwed into the cylinder 6 is adjusted so that after the screw hook 7 is connected to the pump housing core connector, the chain 5 is in a taut state, so that the personnel can lift the pump housing core at the required angle and avoid the angle of the pump housing core being skewed after it is lifted.

[0023] like Figure 1 and Figure 2 As shown, the screw hook 7 includes a second screw 702 threadedly connected to the cylinder 6. A connecting hook 701 is welded to one end of the second screw 702. The chain 5 is connected to the cylinder 6 via the first screw 8. The cylinder 6 is also connected to the connecting hook 701 via the second screw 702. Therefore, when the chain 5 is adjusted to tension, the overall length of the five components (cylinder 6, second screw 702, connecting hook 701, first screw 8, and chain 5) can be adjusted by screwing the first screw 8 or the second screw 702 into the cylinder 6, so that the chain 5 is in a tensioned state.

[0024] Since the rotation of the second screw 702 causes the angle of the connecting hook 701 to change, once the connecting hook 701 is connected to the connecting part of the pump housing core at a suitable angle, the second screw 702 will no longer rotate, and the overall length of the chain 5 will be adjusted by rotating the first screw 8 to ensure that the chain 5 is taut.

[0025] Among them, such as Figure 1 and Figure 3As shown, the fixing device 4 includes a fixing plate 401 fixedly connected to the crossbeam 3. The fixing plate 401 has a through hole 402. The fixing plate 401 is connected to a connecting ring 403 through the through hole 402. One end of the chain 5 is connected to the connecting ring 403. The connecting ring 403 has a large range of motion in the through hole 402. Therefore, when the chain 5 is connected to the connecting ring 403, the adjustable angle of the upper end of the chain 5 is large, so that the connecting hook 701 at the lower end of the chain 5 has a multi-degree-of-freedom space.

[0026] The first screw 8 has a connecting hole 801 at its end outside the cylinder 6. One end of the chain 5 is fixedly connected to the first screw 8 through the connecting hole 801. The connecting hole 801 allows for a large angle adjustment space after the chain 5 is connected to the first screw 8, making it convenient for personnel to connect the connecting hook 701 to the pump housing core by changing the angle of the cylinder 6.

[0027] The working principle is as follows: First, the operator connects the hook of the robot arm 1 to the lifting ring 2. Then, according to the position of the pump housing core connector, the operator manually rotates the second screw 702 so that the connecting hook 701 hooks the pump housing core connector at a suitable angle. Subsequently, the operator manually rotates the first screw 8 to adjust the length of the first screw 8 screwed into the cylinder 6 so that the chain 5 is tensioned, thereby enabling the robot arm 1 to lift the pump housing core through multiple tensioned chains 5.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
