Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum quenching heat treatment technology, and in particular to a workpiece cleaning device for vacuum heat treatment. Background Technology
[0002] Vacuum quenching heat treatment is an advanced process for quenching metal materials in a vacuum environment. By precisely controlling the temperature, pressure and cooling rate, it can significantly improve the mechanical properties and surface quality of the material. After vacuum quenching, a small amount of quenching medium may remain on the surface of the workpiece. The residual medium can affect the adhesion of subsequent processing and even lead to corrosion. Therefore, it is necessary to clean the workpiece. By removing the residual medium, contaminants and potential hazards, cleaning not only meets the needs of subsequent processing, but also improves the corrosion resistance, fatigue resistance and reliability of the material.
[0003] Existing patent CN216369201U discloses a vacuum cleaning machine for heat treatment production, including a shell. A water inlet is provided on one outer surface of the shell, and a sealing cover is provided on the front outer surface of the shell. A hinge is provided between the sealing cover and the shell. A display screen is provided on one side of the sealing cover, and a control panel is provided below the display screen. A partition is fixedly installed on the inner surface of the shell, and a vacuum cleaning chamber is provided on the upper outer surface of the partition. This prior art vacuum cleaning machine for heat treatment production, by setting up a rotating mechanism, after the workpiece is fixed, starts a first drive motor via the control panel. The output shaft of the first drive motor rotates, driving the placement plate at the other end of the rotating shaft to rotate, realizing angle adjustment during workpiece cleaning. This allows for all-around cleaning of the workpiece, improving the cleaning effect and eliminating the need for multiple cleaning cycles, thus bringing better application prospects.
[0004] However, because the above structure does not optimize the specific flow direction of the water after cleaning, the cleaning water is prone to accumulating, which in turn makes it difficult to quickly drain from the placement plate. Utility Model Content
[0005] The purpose of this utility model is to provide a workpiece cleaning device for vacuum heat treatment, which aims to solve the technical problem in the prior art where the cleaning water is prone to water accumulation due to the lack of optimization of the specific flow direction of the water after cleaning in the above structure, thus making it impossible to quickly discharge the placement plate.
[0006] To achieve the above objectives, this utility model employs a workpiece cleaning device for vacuum heat treatment, comprising a placement plate and a vacuum chamber. A guide plate is provided on the upper surface of the placement plate, and a waterproof box is mounted on the placement plate. A tilting motor is installed inside the waterproof box, and a tilting frame is provided at the output end of the tilting motor. Clamping components are provided at both ends of the tilting frame. A vacuum pump is installed on the outside of the vacuum chamber, and multiple C-shaped seats and two hot air blowers are installed on the inside of the vacuum chamber, with the hot air blowers positioned above the C-shaped seats. A water collection tank is located at the bottom of the vacuum chamber. The vacuum chamber has multiple water outlet pipes, each equipped with a control valve. A collection pipe extends below the water outlet pipes and connects to the bottom of the vacuum chamber. A drain pipe is installed on the collection pipe. Multiple spray heads are installed at the top of the vacuum chamber, each connected to a water inlet pipe. A rotary motor is installed below the vacuum chamber, with its output end extending into the chamber. A placement plate is slidably connected to a corresponding C-shaped seat and positioned between the C-shaped seats. The placement plate is also located at the output end of the rotary motor.
[0007] The clamping component includes a clamping plate and a threaded sleeve. The back of the clamping plate is provided with a screw and two positioning rods. One end of the threaded sleeve is provided with a knob. Both ends of the flip frame have rotating holes. The threaded sleeve is rotatably connected to the flip frame and is located in the corresponding rotating hole. The screw is threadedly connected to the threaded sleeve and is located in the threaded sleeve. The two positioning rods pass through the flip frame.
[0008] The C-shaped seat is rotatably equipped with multiple rolling rollers, and the placement plate abuts against the corresponding rolling rollers.
[0009] The vacuum chamber has a conical guide seat at its inner bottom, and the output end of the rotary motor passes through the conical guide seat.
[0010] The water collection tank has guide slopes on both sides, and the water inlet of the outlet has an outlet slope.
[0011] The front end face of the vacuum chamber has a discharge through hole, and a sealing door is hinged to the discharge through hole.
[0012] This utility model discloses a workpiece cleaning device for vacuum heat treatment, comprising a placement plate and a vacuum chamber. A guide plate is provided on the upper surface of the placement plate, and a waterproof box is mounted on the placement plate. A tilting motor is installed inside the waterproof box, and a tilting frame is provided at the output end of the tilting motor. Clamping components are provided at both ends of the tilting frame. A vacuum pump is installed on the outside of the vacuum chamber, and multiple C-shaped seats and two hot air blowers are installed on the inside of the vacuum chamber. A water collection tank is located at the bottom of the vacuum chamber, and multiple water outlet pipes are connected below the water collection tank. Control valves are installed on the water outlet pipes, and a collection pipe is connected below the multiple water outlet pipes. A drain pipe is installed on the collection pipe. Multiple... Each spray head has a rotary motor located below the vacuum chamber. This design provides a clear flow path, allowing the cleaning water to first collect in the water collection tank, then flow into the collection pipe through the outlet pipe, and finally be discharged through the drain pipe. This avoids water accumulation at the placement plate, preventing the water from being unable to drain quickly. Furthermore, the guide slope and outlet slope further guide the water flow, optimizing its direction and ensuring rapid discharge of the cleaning water from the placement plate area. This solves the technical problem of water accumulation and subsequent failure to drain quickly from the placement plate due to the lack of optimization of the water flow direction in the aforementioned structure.

Detailed Implementation
[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0022] Please see Figures 1-5 This utility model provides a workpiece cleaning device for vacuum heat treatment, including a placement plate 1 and a vacuum chamber 2. A guide plate 3 is provided on the upper surface of the placement plate 1. A waterproof box 4 is provided on the placement plate 1. A flipping motor 5 is installed inside the waterproof box 4. A flipping frame 6 is provided at the output end of the flipping motor 5. Clamping components are provided at both ends of the flipping frame 6. A vacuum pump 7 is provided on the outside of the vacuum chamber 2. Multiple C-shaped seats 8 and two hot air blowers 9 are provided on the inside of the vacuum chamber 2, with the hot air blowers 9 located above the C-shaped seats 8. A water collection tank 10 is provided at the bottom of the vacuum chamber 2, and multiple water outlet pipes 1 are connected to the bottom of the water collection tank 10. 1. A control valve 12 is provided on the water outlet pipe 11. A collection pipe 13 is connected to the lower part of the multiple water outlet pipes 11, and the collection pipe 13 extends to the lower part of the vacuum box 2. A drain pipe 14 is provided on the collection pipe 13. Multiple spray heads 15 are provided at the top inside the vacuum box 2, and each of the multiple spray heads 15 is connected to a water inlet pipe 16. A rotary motor 17 is provided at the lower part of the vacuum box 2, and the output end of the rotary motor 17 extends into the vacuum box 2. The placement plate 1 is slidably connected to the corresponding C-shaped seat 8 and is located between the multiple C-shaped seats 8. The placement plate 1 is also located at the output end of the rotary motor 17.
[0023] In this embodiment, by combining the placement plate 1 and the vacuum chamber 2, the workpiece can be cleaned and subsequently vacuum heat treated, completing multiple processes in one device, improving production efficiency and reducing the time and labor costs of transferring workpieces between different devices. The placement plate 1 is equipped with a guide plate 3, and the waterproof chamber 4 contains a flipping motor 5 that drives a flipping frame 6. Clamping elements at both ends of the flipping frame 6 hold the workpiece. This design allows the workpiece to flip during the cleaning process. Combined with the multiple spray nozzles 15 at the top of the vacuum chamber 2, this achieves comprehensive cleaning of the workpiece, improving the cleaning effect. The bottom of the vacuum chamber 2 contains a water collection tank 10, connected to multiple water outlet pipes 11. The water outlet pipes 11 have... The control valve 12 and the multiple water outlet pipes 11 are connected to the collection pipe 13 extending below the vacuum chamber 2. The collection pipe 13 is equipped with the drain pipe 14. This drainage structure can quickly discharge the water after cleaning, avoid water accumulation at the placement plate 1, and ensure the continuity and stability of the cleaning process. The vacuum chamber 2 is equipped with multiple C-shaped seats and two hot air blowers 9 located above the C-shaped seats. The output end of the rotary motor 17 extends into the vacuum chamber 2, and the placement plate 1 is slidably connected to the C-shaped seats and located at the output end of the rotary motor 17. This structure allows the placement plate 1 to rotate under the drive of the rotary motor 17. With the help of the hot air blowers 9, uniform heat treatment of the workpiece can be achieved, improving the heat treatment quality.
[0024] Furthermore, the clamping component includes a clamping plate 18 and a threaded sleeve 19. The back of the clamping plate 18 is provided with a screw 20 and two positioning rods 21. One end of the threaded sleeve 19 is provided with a knob 22. Both ends of the flip frame 6 have rotating holes 23. The threaded sleeve 19 is rotatably connected to the flip frame 6 and is located in the corresponding rotating hole 23. The screw 20 is threadedly connected to the threaded sleeve 19 and is located in the threaded sleeve 19. The two positioning rods 21 pass through the flip frame 6.
[0025] In this embodiment, by rotating the knob 22, the threaded sleeve 19 can be rotated, causing the screw 20 to move the clamping plate 18, thereby achieving flexible clamping of workpieces of different sizes and improving the versatility of the device. The positioning rod 21 plays a positioning and stabilizing role during the clamping process, preventing the clamping plate 18 from shifting during the movement, ensuring that the workpiece is firmly clamped, and guaranteeing the stability of the cleaning and heat treatment processes.
[0026] Furthermore, a plurality of rolling rollers 24 are rotatably disposed inside the C-shaped seat 8, and the placement plate 1 abuts against the corresponding rolling rollers 24.
[0027] In this embodiment, the design of multiple rolling rollers 24 makes the placement plate 1 slide more smoothly on the C-shaped seat, reduces friction, and lowers the resistance when the placement plate 1 moves.
[0028] Furthermore, a conical guide seat 25 is provided at the bottom of the vacuum chamber 2, and the output end of the rotary motor 17 passes through the conical guide seat 25.
[0029] In this embodiment, the conical guide seat 25 can guide the water after cleaning, allowing the water to flow more smoothly to the water collection tank 10. This prevents the water from directly contacting the output end of the rotary motor 17, thus protecting the rotary motor 17, extending the motor's service life, and improving the reliability of the equipment.
[0030] Furthermore, both sides of the water collection tank 10 have guide slopes 26, and the inlet end of the outlet has an outlet slope 27.
[0031] In this embodiment, the guide slope 26 can accelerate the convergence of water to the center of the water collection tank 10, and the outlet slope 27 can make the water enter the outlet pipe 11 more smoothly, further improving the drainage speed and preventing water from stagnating in the water collection tank 10.
[0032] Furthermore, the front end face of the vacuum chamber 2 has a discharge through hole 28, and a sealing door 29 is hinged at the discharge through hole 28.
[0033] In this embodiment, the sealing door 29 can be closed during cleaning and heat treatment to ensure the vacuum environment inside the vacuum chamber 2, prevent outside air from entering and affecting the cleaning and heat treatment effect, and improve the sealing and reliability of the device.
[0034] When using this utility model, by opening the sealing door 29, the workpiece to be cleaned and heat-treated is placed on the placement plate 1. By rotating the knob 22, the threaded sleeve 19 is rotated, causing the screw 20 to move the clamping plate 18. The workpiece is firmly clamped in the flipping frame 6 using the positioning action of the two positioning rods 21. The sealing door 29 is closed, and the vacuum pump 7 is started to achieve the required vacuum environment in the vacuum chamber 2. Multiple spray heads 15 are turned on to clean the workpiece. Simultaneously, the flipping motor 5 is started, causing the flipping frame 6 to rotate, allowing the workpiece to be cleaned from all angles. The cleaned water flows along the guide plate 3 on the placement plate 1 to the vacuum chamber 2. The water flows from the bottom of the empty box 2 into the water collection tank 10, then through multiple water outlet pipes 11 to the collection pipe 13, and finally out through the drain pipe 14. After cleaning, the spray head 15 is turned off, the two hot air blowers 9 are turned on, and the rotary motor 17 is started at the same time. The rotary motor 17 drives the placement plate 1 to slide between multiple C-shaped seats, and the placement plate 1 rotates under the drive of the rotary motor 17. In conjunction with the hot air blowers 9, the workpiece is subjected to uniform heat treatment. In this way, the technical problem that the cleaning water is prone to water accumulation and cannot be quickly discharged from the placement plate 1 because the above structure does not optimize the specific flow direction of the cleaning water is not optimized.
[0035] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
