[0002] The valve plate is one of the key components in the valve. Its heat treatment process is crucial to improving the service life and performance of the valve. During heat treatment, the workpiece is placed in a certain medium and heated to a suitable temperature. After being kept at this temperature for a certain period of time, it is cooled at different speeds in different media. This is a process that controls its performance by changing the microstructure of the surface or interior of the metal material.

[0003] When the valve plate is heat treated, it is necessary to restrict and fix the workpiece with the help of a placement device to avoid displacement of the workpiece during the heat treatment process. For example, the Chinese utility model patent with patent publication number CN221051943U includes a base and two support frames. The upper surface of the base is fixed with a lifting ear. The support frame is arranged on the left side of the top of the base and is symmetrically arranged front and back. A plurality of support members are symmetrically fixed on the left and right sides of the support frame. The support frame has a triangular structure. Moving blocks are symmetrically fixed on the left and right sides of the bottom of the support frame, and the bottom of the moving block is rotatably connected to a roller. The top of the base is provided with a slide groove slidably connected to the corresponding left and right rollers. The top of the base is located at the front and rear sides of the two support frames and is fixedly connected with support rods, and a cross bar is fixedly connected between the tops of the support rods. This patent can facilitate the adjustment of the distance between the two support frames by setting a movable block, a roller, a fixed block and a cross bar, thereby solving the problem that the prior art is not convenient for fixing shorter shaft workpieces, and improves the application range of the clamp. However, when clamping and fixing multiple workpieces, it is necessary to turn multiple hand wheels to fix them in sequence. When performing large-scale processing, the fixing and disassembly of the workpieces will consume a lot of processing time, which is inconvenient. In view of this, we propose a valve plate casting heat treatment placement device. Utility Model Content

When the second installation sleeve moves, it will simultaneously drive the upper placement plate to descend, so that the valve plate is fixed by the upper placement plate, and after fixation, the through groove can be used to allow heat to pass through to avoid uneven heating. Through the above structure, it can be more convenient to fix the valve plate during heat treatment.

When the second mounting sleeve 6 moves, it will simultaneously drive the upper placement disk 7 to descend, so that the valve plate is fixed by the upper placement disk 7, and after fixation, the through groove 9 can be used to allow heat to pass through to avoid uneven heating. Through the above structure, it can be more convenient to fix the valve plate during heat treatment. Only one driving assembly is needed to cooperate with all the second mounting sleeves 6 to drive the upper placement disk 7 to move, thereby completing batch clamping at one time, reducing the time required for disassembly and fixation during batch processing.

[0024] Furthermore, the driving assembly includes a threaded rod 10, which is rotatably connected to the bottom wall of the mounting column 2. A threaded sleeve 11 is provided on the outer surface of the threaded rod 10. The threaded sleeve 11 is fixedly connected to one side of the second mounting sleeve 6 extending into the interior of the mounting column 2. A telescopic groove 12 is provided at the upper end of the threaded rod 10. A spring 13 is fixedly connected to the bottom wall of the telescopic groove 12.

When fixing, the driving knob 15 is installed downward. When the driving knob 15 moves, the L-shaped rod 20 is synchronously used to drive the sliding block 19 to move. After the sliding block 19 moves, it enters the interior of the rotating ring groove 16. When the driving knob 15 is lowered, the displacement rod 14 is synchronously used to compress the spring 13. At this time, the driving knob 15 cooperates with the displacement rod 14 to drive the threaded rod 10 to rotate. Since the movement trajectory of the second mounting sleeve 6 is limited by the sliding groove 5, when the threaded rod 10 rotates, it will synchronously drive the second mounting sleeve 6 to move synchronously, and then drive the placement plate 7 to move. After the fixing is completed, release. The driving knob 15 uses the elastic force of the spring 13 to push the sliding block 19 back into the locking groove 17.

Through the above structure, when processing valve plates of different specifications, the placement plate 7 can be replaced more conveniently. At the same time, the cooperation between the sliding block 19 and the locking groove 17 can avoid the displacement and unlocking of the placement plate 7 due to accidental touch.

[0025] Working principle: When fixing, the driving knob 15 is installed downward. When the driving knob 15 moves, the L-shaped rod 20 will be used to drive the sliding block 19 to move. After the sliding block 19 moves, it enters the interior of the rotating ring groove 16. When the driving knob 15 is lowered, the displacement rod 14 will be used to compress the spring 13. At this time, the driving knob 15 cooperates with the displacement rod 14 to drive the threaded rod 10 to rotate. Since the movement trajectory of the second mounting sleeve 6 is restricted by the sliding groove 5, when the threaded rod 10 rotates, the second mounting sleeve 6 will be driven to move synchronously, and then the placement plate 7 will be driven to move. After the fixing is completed, the driving knob 15 is released and the elastic force of the spring 13 is used to push the sliding block 19 back to the interior of the locking groove 17. When the sliding block 19 rises, it is positioned with the help of the positioning groove 18 to reduce the probability of getting stuck. When changing the product specifications, the bolt 24 can be twisted off, and then the placement plate 7 can be rotated to disengage the second mounting ear 25 from the mounting ear 21.
