For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example 1

[0031] This embodiment provides a palladium high temperature treatment device, such as Figure 1 As shown, it includes an annealing furnace 1, the inner wall of the annealing furnace 1 is slidably connected with an annealing platform 4, and the front opening of the annealing furnace 1 is slidably connected with a closed door 3. A heating device is arranged inside the annealing furnace 1 for heat treatment of palladium to improve the thermal high temperature capacity of palladium. The closed door 3 is used to close the front opening of the annealing furnace 1. The annealing furnace 1 and the closed door 3 form a closed space to prevent the heat loss inside the annealing furnace 1.

[0032] like Figure 2 and 3 As shown, a flip assembly 5 is provided on the top of the annealing platform 4. The flip assembly 5 includes a sleeve 51, a clamp, a flat insert disc 55, a docking block 56 and a protrusion 57. The clamp is fixedly installed at the end of the sleeve 51. The side of the clamp away from the sleeve 51 is in contact with the workpiece. Two clamps are provided, which are respectively located on both sides of the workpiece. The position of the workpiece is fixed by clamping the clamp. The workpiece is palladium.

[0033] The inner wall of the sleeve 51 is slidably connected with a slide rod 52, and a slide bar is fixedly installed on the rod body of the slide rod 52. The slide bar is slidably connected to the sleeve 51. When the sleeve 51 and the slide rod 52 rotate, the slide bar prevents the sleeve 51 and the slide rod 52 from rotating relative to each other.

[0034] like Figure 3 As shown, a flat insert disc 55 is arranged at the other end of the sleeve 51, and the inner wall of the annealing furnace 1 is rotatably connected to a docking block 56, and two symmetrically arranged protrusions 57 are fixedly installed on the inner arc surface of the docking block 56, and the flat insert disc 55 is engaged with the protrusions 57, and there is a gap between the two protrusions 57. A notch for engaging the protrusions 57 is provided at the arc of the flat insert disc 55, and a stopper for being engaged between the two protrusions 57 is provided at the notch of the flat insert disc 55. An external stepping motor 58 is fixedly installed on the side of the annealing furnace 1, and the side of the protrusion 57 is fixedly connected to the external stepping motor 58 through a rotating shaft.

[0035] The annealing platform 4 is moved to move the flat disc 55, and the flat disc 55 is docked with the protrusion 57 on the docking block 56 through the movement of the flat disc 55. The docking block 56 is driven to rotate by the external stepping motor 58, and the protrusion 57 on the docking block 56 drives the flat disc 55 to rotate, so that the slide bar 52 and the sleeve 51 on the side of the docking block 56 rotate, so that the clamp rotates, and the workpiece is driven to rotate by the rotation of the clamp, and the workpiece is continuously rotated and turned over.

[0036] The external stepper motor 58 drives the docking block 56 to rotate and controls the rotation angle of the docking block 56 so that after the docking block 56 rotates, the opening of the docking block 56 always faces the protrusion 57, and the notch on the disk 55 can be adjusted before entering the annealing furnace 1, so that the notch on the disk 55 can always dock with the protrusion 57.

[0037] A positioning frame 6 is fixedly installed on the top of the annealing platform 4. The positioning frame adopts an inverted U-shaped structure. The slide bar 52 passes through the positioning frame 6 and is rotatably connected thereto. The flat inserting disc 55 rotates on the side of the positioning frame 6. Therefore, when the slide bar 52 is extended and retracted, the flat inserting disc 55 is always located on the side of the positioning frame 6, and the flat inserting disc 55 will not be displaced along the direction of the slide bar 52.

[0038] After the annealing platform 4 completely enters the annealing furnace 1, the closing door 3 falls to close the annealing furnace and restrict the movement of the annealing platform 4. After the annealing platform 4 enters the annealing furnace 1, its position remains unchanged, so the flat insert disc 55 located on the annealing platform 4 remains unchanged after entering the annealing furnace, so the disc 55 and the protrusion 57 on the docking block 56 will not separate after docking.

[0039] like Figure 2 As shown, the fixture includes a turntable 53 and a clamping block 54. The end of the sleeve 51 is fixedly connected to the turntable 53. A plurality of clamping blocks 54 distributed in a ring with equal angles are fixedly installed on the side of the turntable 53 away from the sleeve 51. There is a spacing between the clamping blocks 54 at adjacent positions. The side of the clamping blocks 54 away from the turntable 53 is in contact with the workpiece.

[0040] The sleeve 51, the slide bar 52, the turntable 53, the clamping block 54, the flat insert disc 55, the docking block 56 and the protrusion 57 are all made of heat-resistant steel of model 3Cr24N i 7S i NRe. The annealing temperature of the palladium workpiece is between 800°C and 1000°C. The motor and the electric push rod device cannot be used inside the annealing furnace 1. By using heat-resistant steel of model 3Cr24N i 7Si NRe, melting is avoided. The external stepper motor 58 is located outside the annealing furnace 1 and is not affected by high temperature.

[0041] In this embodiment, the position of the palladium workpiece is fixed by a clamp, and the annealing platform 4 sends the clamp and the palladium workpiece into the annealing furnace 1. The protrusion 57 on the docking block 56 is engaged with the notch of the flat insert disc 55. The docking block 56 is driven to rotate by the external stepper motor 58, so that the flat insert disc 55 and the sleeve 51 rotate, thereby rotating the clamp, and the palladium clamped by the clamp is continuously turned over and changed position, so that the palladium workpiece is heated evenly, thereby improving the high temperature resistance of the palladium.

[0042] Example 2

[0043] Based on Example 1, this example proposes a palladium high temperature treatment device, such as Figure 4 As shown, the annealing platform 4 includes a platform body 41, a slider 42 and a screw 44. A horizontal groove is provided on the top of the platform body 41, the slider 42 slides in the horizontal groove of the platform body 41, and both ends of the screw 44 are rotatably connected to the platform body 41.

[0044] A support frame 45 is fixedly installed on the top of the slider 42. The support frame 45 adopts an inverted U-shaped structure. A limit block 43 is fixedly installed at the top center of the platform body 41. The limit block 43 is used to limit the position of the platform body 41. All structures of the annealing platform 4 are made of heat-resistant steel of model 3Cr24Ni7SiNRe.

[0045] like Figure 4 As shown, the screw rod 44 passes through the stop block 43, and the stop block 43 divides the screw rod 44 into two parts, the left and right parts of the screw rod 44, and the threads on the left and right parts of the screw rod 44 are in opposite directions. Manually rotating the screw rod 44 can move the slider 42 on it in the opposite or opposite directions, adjust the position of the support frame 45, that is, adjust the clamping distance of the clamp, and increase the adaptability range of the palladium workpiece.

[0046] When adjusting the position of the support frame 45, the sleeve 51 moves with the support frame 45, and the sleeve 51 and the slide rod 52 play a telescopic role. A limit block is provided at the notch of the flat insert disc 55 to be clamped between the two protrusions 57 to prevent the flat insert disc 55 and the protrusion 57 from separating when the sleeve 51 and the slide rod 52 are telescoped.

[0047] The bottom of the platform body 41 is rotatably connected to a roller via a rotating shaft, the side of the platform body 41 is slidably connected to the annealing furnace 1, and a track 2 is fixedly installed on the inner wall of the annealing furnace 1, and the roller rolls in the track 2. The position of the platform body 41 is shifted by the cooperation of the roller and the track 2, and the fixture and the palladium workpiece are sent into the annealing furnace 1 for high-temperature heating.

[0048] In this embodiment, the screw rod 44 is manually rotated to move the slider 42 thereon in the direction toward or away from each other, thereby adjusting the position of the support frame 45, that is, adjusting the clamping distance of the clamp, thereby increasing the adaptability range of the palladium workpiece.

[0049] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
