Description

Technical Field

[0001] This invention relates to the field of handling device technology, and in particular to a high-temperature resistant gripper and a handling device having the same. Background Technology

[0002] When machining metal parts, they need to be heated to a high temperature that makes them easily deformable before forming. During the forming process, the metal parts need to be transferred. Existing grippers will deform after working at high temperatures for a long time, leading to unstable clamping. Furthermore, heat will be transferred to the drive mechanism through the grippers, affecting the service life of the drive mechanism.

[0003] Based on the above-mentioned technical problems, this application proposes a high-temperature resistant gripper and a handling device having the same. Summary of the Invention

[0004] The purpose of this invention is to provide a high-temperature resistant gripper and a handling device having the same, so as to solve the technical problems mentioned in the background art. This purpose is achieved through the following technical solution: A high-temperature resistant gripper includes a base with two rotating shafts arranged in parallel on the base. A gripper block is fixed to one end of each rotating shaft, and a drive gear is fixed to the other end of each rotating shaft. A telescopic drive component is installed on the base, and a drive rack is fixed to the telescopic end of the telescopic drive component. The drive rack is located between the two drive gears, and both drive gears mesh with the drive rack.

[0005] Furthermore, a connecting sleeve is provided on the base, and bearings are provided at both ends of the connecting sleeve. The rotating shaft is installed inside the connecting sleeve through the bearings.

[0006] Furthermore, end caps are provided at both ends of the connecting sleeve, and the end caps and the connecting sleeve form a sealed cooling cavity. Cooling medium inlet and cooling medium outlet are respectively opened on the connecting sleeve, and both the cooling medium inlet and cooling medium outlet are connected to the cooling cavity.

[0007] Furthermore, the telescopic drive component is one of a pneumatic cylinder, an electric actuator, or a hydraulic cylinder.

[0008] Furthermore, a dust cover is provided on one side of the base, and the drive gear and drive rack are both located inside the dust cover.

[0009] A high-temperature resistant handling device includes any of the above-mentioned high-temperature resistant grippers, which are mounted on a handling robot.

[0010] Furthermore, there are at least two high-temperature resistant grippers.

[0011] The technical solutions provided in this application have at least the following technical effects or advantages: 1. By installing the clamping block and the drive gear at both ends of the rotating shaft, the distance between the clamping jaws and the telescopic drive component is increased, thus avoiding the influence of high-temperature workpieces on the telescopic drive component and extending the service life of the high-temperature resistant clamping jaws; 2. The action of the gripper is achieved by the cooperation of the drive rack and drive gear, which reduces the contact area between the gripper and the telescopic drive component, reduces the heat conduction between the gripper and the telescopic drive component, and further reduces the impact of high temperature on the telescopic drive component; 3. By introducing cooling medium into the sealed connecting sleeve through the cooling medium inlet and outlet, the cooling efficiency of the rotating shaft can be improved, heat can be prevented from being transferred from the rotating shaft to the telescopic drive component, and the high temperature resistance of the gripper can be improved.

[0015] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0016] Example 1 like Figure 1-3The high-temperature resistant gripper shown includes a base 1, which is a square tube structure. Two cylindrical connecting sleeves 2 are mounted parallel to each other on the base 1. The length of the connecting sleeves 2 is 300-500mm. Bearings 21 are installed at both ends of the connecting sleeves 2. A rotating shaft 3 made of heat-resistant mold steel is installed between the two bearings 21, with both ends of the rotating shaft 3 extending beyond the bearings 21. A stainless steel cast clamping block 4 is fixed to the left end of the rotating shaft 3, and a drive gear 5 is fixed to the right end of the rotating shaft 3. A telescopic drive component 6 is installed on the base 1. The telescopic drive component 6 is vertically installed between the two rotating shafts 3 via a connecting plate 61. The telescopic drive component 6 can be a cylinder, an electric actuator, or a hydraulic cylinder, preferably a cylinder. A drive rack 7 is fixed to the telescopic end of the telescopic drive component 6. The drive rack 7 is vertically installed between the two drive gears 5, and both drive gears 5 mesh with the drive rack 7 to achieve synchronous and opposite rotation of the two drive gears 5.

[0017] When the telescopic drive 6 moves the drive rack 7 upward, the two clamping blocks 4 flip inward simultaneously to clamp the high-temperature workpiece; when the telescopic drive 6 moves the drive rack 7 downward, the two clamping blocks 4 flip outward simultaneously to release the high-temperature workpiece.

[0018] By placing the clamping block 4 and the drive gear 5 at opposite ends of the rotating shaft 3, the heat conduction path can be effectively extended. Furthermore, the gear-rack transmission structure effectively reduces the heat conduction path. When clamping a workpiece at 800°C, the cylinder position temperature does not exceed 80°C, far lower than the 150°C often seen in ordinary grippers, significantly extending the lifespan of the cylinder and cylinder seals.

[0019] The clamping block 4 and the drive gear 5 are respectively fixed to both ends of the rotating shaft 3 by screws, allowing for easy replacement of the clamping block 4 and the drive gear 5, facilitating maintenance of the high-temperature gripper. A dust cover 8 is also installed on the right side of the base 1, with the drive gear 5 and drive teeth 7 located inside the dust cover 8. The gear-rack meshing transmission offers high precision and good synchronization. The dust cover 8 reduces dust accumulation, making it suitable for harsh working conditions, and also blocks some radiant heat.

[0020] In a preferred embodiment of this application, end caps 22 are fixed to both ends of the connecting sleeve 2. The end caps 22 are connected to the connecting sleeve 2 by bolts and form a sealed cooling cavity. A cooling medium inlet (not shown) is provided at the lower part of the connecting sleeve 2, and a cooling medium outlet (not shown) is provided at the upper part of the connecting sleeve 2. Both the cooling medium inlet and the cooling medium outlet are connected to the cooling cavity. In use, circulating cooling water is introduced into the cooling cavity through the cooling medium inlet and flows out from the cooling medium outlet to remove the heat on the rotating shaft 3 and prevent the heat from being guided from the rotating shaft 3 to the telescopic drive member 6.

[0021] Cooling with circulating water keeps the operating temperature of the rotating shaft 3 below 100°C, preventing thermal expansion from causing jamming, while also protecting the bearings and gear lubrication and extending the service life of the grippers.

[0022] Example 2 like Figure 4 The high-temperature resistant handling device shown includes four sets of high-temperature resistant grippers as in Embodiment 1 and a handling robot 9. The four sets of high-temperature resistant grippers are arranged in a straight line on the same base 1. The handling robot 9 is a six-axis handling robot. The base 1 is installed at the end of the arm of the handling robot 9 through a flange. The air circuit and cooling water circuit are integrated and connected through the internal channel or external pipeline of the handling robot 9. The system is programmable and controllable to realize the gripping, transfer and placement of high-temperature workpieces. The applicable workpiece temperature can reach above 800°C.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
