Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a heat treatment fixture for stainless steel parts. Background Technology

[0002] In the aerospace, automotive manufacturing, and high-end equipment industries, stainless steel parts often reach surface temperatures of several hundred degrees Celsius after heat treatments such as solution treatment, aging, or quenching. The workpiece's microstructure remains in a state of expansion or unstable stress, requiring rapid transfer to the next cooling or shaping station. To ensure continuous production, automatic loading and unloading fixtures are commonly installed at the outlet of heat treatment furnaces.

[0003] Because the clamping jaws and the workpiece have different coefficients of thermal expansion, the clamping force decreases as the temperature rises, and the parts are prone to loosening or even slipping. Existing fixtures lack effective anti-fall mechanisms. Once the clamping fails, the high-temperature parts will fall directly, causing equipment damage and safety hazards.

[0004] Therefore, a heat treatment fixture for stainless steel parts is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a heat treatment fixture for stainless steel parts in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A heat treatment fixture for stainless steel parts includes a mounting frame. A first motor is fixedly mounted on the top surface of the mounting frame. A first rotating shaft is fixedly connected to the output end of the first motor. A support plate is fixedly connected to the bottom end of the first rotating shaft. Third electric push rods are fixedly mounted on the left and right sides of the top surface of the support plate. A mounting plate is fixedly connected to the telescopic end of the third electric push rod. A sliding column is fixedly connected to the top surface of the mounting plate and is movably inserted into the support plate. A telescopic control assembly is mounted on the surface of the mounting plate. A clamping assembly is provided on the surface of the telescopic control assembly. A fall protection assembly is provided below the telescopic control assembly. A locking assembly is mounted on the surface of the fall protection assembly.

[0007] Furthermore, the telescopic control assembly includes a first electric push rod, which is fixedly mounted on the surface of the mounting plate. The telescopic end of the first electric push rod is fixedly connected to a mounting shell, and a sleeve is movably sleeved on the end of the mounting plate, with the end of the sleeve fixedly connected to the mounting shell.

[0008] Furthermore, the clamping assembly includes a second motor, which is fixedly mounted on the front of the mounting housing. A double-ended screw is fixedly connected to the output end of the second motor. Two connecting rods are threadedly connected to the surface of the double-ended screw, and the connecting rods are movably inserted into the mounting housing. A clamping plate is fixedly connected to the end of each connecting rod.

[0009] Furthermore, the fall arrestor includes a fixed frame, which is fixedly connected to the bottom surface of the sleeve. A second electric push rod is fixedly installed on the surface of the fixed frame. A U-shaped bracket is fixedly connected to the telescopic end of the second electric push rod. A second rotating shaft is rotatably connected to the surface of the U-shaped bracket. A support plate is fixedly connected to the surface of the second rotating shaft.

[0010] Furthermore, the locking assembly includes a pin, which is movably inserted into the U-shaped bracket. One end of the pin is fixedly connected to an end block, and a spring is fixedly connected between the end block and the U-shaped bracket. The other end of the pin is fixedly connected to an installation rod, and an L-shaped insert is fixedly connected to the bottom surface of the installation rod. The surface of the support plate has a groove, and the inner wall of the groove is movably inserted into the end of the L-shaped insert.

[0011] Furthermore, the clamping plate is made of a nickel-based alloy.

[0012] The beneficial effects of this utility model are as follows: The telescopic control component drives the clamping assembly to approach the heat-treated stainless steel part. A third electric push rod then moves the support plate downwards, causing the mounting plate and clamping assembly to descend. The clamping assembly clamps and secures the stainless steel part. The telescopic control component then retracts and resets the clamping assembly. An anti-fall component moves to below the clamping assembly, preventing the part from falling. A first motor drives the first rotating shaft and support plate to rotate, which in turn rotates the mounting plate and clamping assembly, bringing the stainless steel part to the unloading position. After the anti-fall component resets, the clamping assembly releases the part, completing the unloading process. Meanwhile, another set of clamping components is positioned at the heat-treated part's location and can perform clamping operations simultaneously. This invention effectively clamps heat-treated parts, preventing accidental drops and making the clamping process more stable and safe. Attached Figure Description

[0019] like Figures 1 to 3 As shown, a heat treatment fixture for stainless steel parts includes a mounting frame 1. A first motor 2 is fixedly mounted on the top surface of the mounting frame 1. A first rotating shaft 3 is fixedly connected to the output end of the first motor 2. A support plate 4 is fixedly connected to the bottom end of the first rotating shaft 3. A third electric push rod 10 is fixedly mounted on both the left and right sides of the top surface of the support plate 4. A mounting plate 6 is fixedly connected to the telescopic end of the third electric push rod 10. A sliding column 11 is fixedly connected to the top surface of the mounting plate 6, and the sliding column 11 is movably inserted into the support plate 4. A telescopic control assembly 7 is mounted on the surface of the mounting plate 6. The telescopic control assembly 7 includes a first electric push rod 701, and the first electric push rod 701 is fixedly mounted on the surface of the mounting plate 6. A mounting shell 702 is fixedly connected to the telescopic end of the first electric push rod 701. A sleeve 703 is movably sleeved on the end of the mounting plate 6, and the end of the sleeve 703 is fixedly connected to the mounting shell 702. It should be noted that by operating the first electric push rod 701, the mounting shell 702 is driven to move, which in turn drives the clamping assembly 8 to move, so that the clamping assembly 8 is close to the heat-treated stainless steel part. During the movement of the mounting shell 702, the sleeve 703 will slide along the surface of the mounting plate 6 to support and limit the mounting shell 702.

[0020] The telescopic control assembly 7 has a clamping assembly 8 on its surface. The clamping assembly 8 includes a second motor 801, which is fixedly mounted on the front of the mounting housing 702. A double-ended screw 802 is fixedly connected to the output end of the second motor 801. Two connecting rods 803 are threadedly connected to the surface of the double-ended screw 802, and the connecting rods 803 are movably inserted into the mounting housing 702. A clamping plate 804 is fixedly connected to the end of the connecting rod 803. More specifically, when the second motor 801 operates, it drives the double-ended screw 802 to rotate. Under the action of the threads, the connecting rods 803 move, which in turn pushes the clamping plate 804 to move, thereby clamping and fixing the stainless steel parts.

[0021] The clamping plate is made of 804 nickel-based alloy. It should be noted that nickel-based alloys have good heat resistance and can be used for stainless steel parts that come into contact with high temperatures.

[0022] Below the telescopic control assembly 7 is an anti-fall assembly 9, which includes a fixing frame 901 fixedly connected to the bottom surface of the sleeve 703. A second electric push rod 902 is fixedly mounted on the surface of the fixing frame 901. A U-shaped bracket 903 is fixedly connected to the telescopic end of the second electric push rod 902. A second rotating shaft 904 is rotatably connected to the surface of the U-shaped bracket 903, and a support plate 905 is fixedly connected to the surface of the second rotating shaft 904. It should be noted that the operation of the second electric push rod 902 drives the U-shaped bracket 903 to move, thereby pushing the second rotating shaft 904 and the support plate 905 to move, so that the support plate 905 reaches below the clamping plate 804, preventing parts from falling.

[0023] A locking component 5 is installed on the surface of the fall arrestor 9. The locking component 5 includes a pin 501, which is movably inserted into the U-shaped bracket 903. One end of the pin 501 is fixedly connected to an end block 503, and a spring 504 is fixedly connected between the end block 503 and the U-shaped bracket 903. The other end of the pin 501 is fixedly connected to an installation rod 502, and an L-shaped insert 505 is fixedly connected to the bottom surface of the installation rod 502. The surface of the support plate 905 has a groove, and the inner wall of the groove is movably inserted into the end of the L-shaped insert 505. More specifically, under normal conditions, the L-shaped insert 505 is inserted into the inner wall of the groove, allowing the tray 905 to remain horizontal. If a stainless steel part falls onto the surface of the tray 905, by pulling the mounting rod 502, the insert 501 and end block 503 are moved, overcoming the elastic force of the spring 504. The mounting rod 502 will then pull the L-shaped insert 505 away from the inner wall of the groove, thus releasing the restriction on the tray 905. The tray 905 containing the part will then deflect to one side, making it easier to unload the part.

[0024] In summary: The telescopic control component 7 drives the clamping component 8 to approach the heat-treated stainless steel part. The third electric push rod 10 drives the support plate 4 downwards, which in turn lowers the mounting plate 6 and the clamping component 8. The clamping component 8 clamps and secures the stainless steel part. The telescopic control component 7 then retracts and resets. The anti-fall component 9 then moves to below the clamping component 8, blocking it from falling. The first motor 2 drives the first rotating shaft 3 and the support plate 4 to rotate, which in turn rotates the mounting plate 6 and the clamping component 8, bringing the stainless steel part to the unloading position. After the anti-fall component 9 resets, the clamping component 8 releases the clamp, completing the unloading process. Meanwhile, another set of clamping components 8 is positioned at the heat-treated part's location, allowing for simultaneous clamping operations. This invention effectively clamps heat-treated parts, preventing accidental drops and making the clamping process more stable and safe.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
