Description

Technical Field

[0001] This utility model relates to the field of normalizing device technology, specifically to a universal joint bushing normalizing device with a filter mechanism. Background Technology

[0002] Universal joint bushings require normalizing primarily to improve their microstructure and properties. Normalizing, as a heat treatment process, involves heating the metal to 30-50°C above its critical temperature, holding it at that temperature for an appropriate time, and then cooling it in air. Normalizing equipment typically uses natural gas as a heat source; the combustion of the gas releases a large amount of heat energy, which is used to heat the workpiece. This method has advantages such as low cost and high heating efficiency.

[0003] Existing normalizing devices do not have the function of filtering the gas. During the production or transportation process, particulate matter is easily generated inside the gas. This particulate matter can easily cause blockage inside the gas heating device, affecting the stability of heating the workpiece and thus affecting the normalizing quality of the workpiece. Utility Model Content

[0004] The purpose of this invention is to provide a universal joint bushing normalizing device with a filter mechanism, which solves the problem in the prior art that particulate matter inside the gas can easily cause blockage of the main body of the gas heating device, thereby affecting the normalizing effect of the universal joint bushing.

[0005] This utility model provides the following technical solution: a normalizing device for a universal joint bushing with a filtering mechanism, comprising:

[0006] A base, on the top of which a gas heating device body is fixedly installed, and on the top of which a normalizing furnace body is fixedly installed;

[0007] A gas filtration mechanism is installed on the top of the base and is used to filter the gas used by the main body of the gas heating device.

[0008] A workpiece moving mechanism is installed on the main body of the normalizing furnace and is used to automatically put in or take out workpieces.

[0009] As a preferred embodiment of the above technical solution, the gas filtration mechanism includes a filter pipe, which is fixedly installed on the top of the base. An output port is fixedly connected to the top of the filter pipe. The end of the output port away from the filter pipe is fixedly connected to the gas-using end of the main body of the gas heating device through a gas pipe. An input port is fixedly connected to the back of the filter pipe.

[0010] As a preferred embodiment of the above technical solution, a sealing cover is movably inserted into the front of the filter pipe, and protrusions are fixedly installed on both sides of the sealing cover. A locking bolt is threadedly connected to the side of the protrusion, and the threaded end of the locking bolt is movably connected to the outer wall of the filter pipe.

[0011] The above technical solution, through the design of the protrusion and locking bolt, allows the sealing cover to be detachably connected to the filter pipe, facilitating cleaning and maintenance.

[0012] As a preferred embodiment of the above technical solution, a connecting rod is fixedly installed on the back of the sealing cover, a square plate is fixedly installed on the end of the connecting rod away from the sealing cover, a raised inner frame is fixedly installed on the front of the square plate, a connecting frame is movably sleeved on the outer wall of the raised inner frame, a connecting bolt is threaded to the side of the connecting frame, the threaded end of the connecting bolt is movably connected to the outer wall of the raised inner frame, and a filter cover is fixedly installed at the end of the connecting frame.

[0013] The above technical solution, through the design of the filter cover, can filter the gas and ensure the stability of the main operation of the gas heating device.

[0014] As a preferred embodiment of the above technical solution, a limiting support rod is fixedly installed on the front of the square plate, a connecting leg is slidably connected to the outer wall of the limiting support rod, a cover plate is fixedly installed at the end of the connecting leg, the back of the cover plate is movably connected to the front of the square plate, an elastic element is fixedly connected to the front of the square plate, and the end of the elastic element away from the square plate is fixedly connected to the back of the connecting leg.

[0015] Through the above technical solution, the design of limiting support rod, elastic element, connecting support leg and cover plate can block impurities in the inner cavity of the filter cover, which facilitates the cleaning work.

[0016] As a preferred embodiment of the above technical solution, the workpiece moving mechanism includes a synchronous electric cylinder, which is fixedly installed on the top of the main body of the normalizing furnace. A furnace door is fixedly installed on the telescopic end of the synchronous electric cylinder, and a support frame is fixedly installed on the left side of the furnace door.

[0017] Through the above technical solution, by designing a synchronous electric cylinder to control its extension and retraction, workpieces can be automatically placed or removed.

[0018] As a preferred embodiment of the above technical solution, a support rod is fixedly installed on the inner wall of the support frame near the bottom, and a heat insulation plate is fixedly installed on the left side of the support frame.

[0019] Through the above technical solution, the design of the heat insulation plate can seal the opening of the main body of the normalizing furnace after the furnace door is moved and opened, thereby reducing the heat loss inside the main body of the normalizing furnace.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This utility model, through the overall design of the gas filtration mechanism, allows the gas used by the main body of the gas heating device to flow through the inner cavity of the filter pipe. During the gas flow, the filter cover filters the gas, removing particulate matter and other impurities from inside the gas. This prevents impurities from easily causing internal blockages in the main body of the gas heating device, ensuring the stability of the gas heating device in heating the workpiece, and thus ensuring the normalizing quality of the workpiece. Furthermore, through the cooperation of the square plate, limiting support rod, elastic element, connecting support leg, and cover plate, the filtered impurities can be locked in the inner cavity of the filter cover when it is disassembled and cleaned, preventing impurities from scattering into the filter pipe and causing significant obstacles to the cleaning work.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figures 1-5 As shown, this utility model provides a technical solution: a normalizing device for a universal joint bushing with a filtering mechanism, comprising:

[0030] A base 1, a gas heating device body 11 is fixedly installed on the top of the base 1, and a normalizing furnace body 12 is fixedly installed on the top of the gas heating device body 11.

[0031] Gas filtration mechanism 2 is installed on the top of the base 1 and is used to filter the gas used by the main body 11 of the gas heating device.

[0032] The workpiece moving mechanism 3 is installed on the main body 12 of the normalizing furnace and is used to automatically put in or take out the workpiece.

[0033] As one implementation method in this embodiment, such as Figures 1-4 As shown, the gas filtration mechanism 2 includes a filter pipe 21, which is fixedly installed on the top of the base 1. An output port 22 is fixedly connected to the top of the filter pipe 21. The end of the output port 22 away from the filter pipe 21 is fixedly connected to the gas-using end of the gas heating device body 11 via a gas pipe. An input port 23 is fixedly connected to the back of the filter pipe 21. A sealing cover 24 is movably inserted into the front of the filter pipe 21. Protrusions 25 are fixedly installed on both sides of the sealing cover 24. Locking bolts 26 are threadedly connected to the sides of the protrusions 25, and the threaded ends of the locking bolts 26 are movably connected to the outer wall of the filter pipe 21. A connecting rod 27 is fixedly installed on the back of the sealing cover 24. A square plate 28 is fixedly installed at the end of the connecting rod 27 away from the sealing cover 24. A raised inner frame 29 is fixedly installed on the front of the square plate 28. A connecting frame 291 is movably sleeved on the outer wall of the raised inner frame 29. A connecting bolt 292 is threadedly connected to the side of the connecting frame 291. The threaded end of the connector 292 is movably connected to the outer wall of the raised inner frame 29. The end of the connecting frame 291 is fixedly installed with a filter cover 293. The gas source pipe is connected to the inlet 23. When the main body 11 of the gas heating device is working, the gas used flows through the inner cavity of the filter pipe 21. During the gas flow, the filter cover 293 can filter the gas and remove impurities such as particulate matter inside the gas, thereby ensuring the normalizing quality of the workpiece. If the filter cover 293 needs to be cleaned, first close the valve of the gas source, then loosen the locking bolt 26 so that its end is away from the outer wall of the filter pipe 21. Then the sealing cover 24 can be pulled out from the front of the filter pipe 21 and the filter cover 293 can be removed as a whole. Then the connector 292 can be loosened so that its end is away from the outer wall of the raised inner frame 29. Then the filter cover 293 can be pulled out from the raised inner frame 29 to facilitate cleaning of the inner cavity of the filter cover 293.

[0034] As one implementation method in this embodiment, such as Figure 4As shown, a limiting support rod 281 is fixedly installed on the front of the square plate 28. A connecting leg 283 is slidably connected to the outer wall of the limiting support rod 281. A cover plate 284 is fixedly installed at the end of the connecting leg 283. The back of the cover plate 284 is movably connected to the front of the square plate 28. An elastic element 282 is fixedly connected to the front of the square plate 28. The end of the elastic element 282 away from the square plate 28 is fixedly connected to the back of the connecting leg 283. When the gas flows through the filter pipe 21, it will push the cover plate 284, causing the cover plate 284 to move with the help of the connecting leg 283. Leg 283 slides forward on the outer wall of the limiting support rod 281, while stretching the elastic element 282. The gas flows through the gap between the square plate 28 and the cover plate 284. When the gas stops flowing, the reset force of the elastic element 282 can drive the connecting leg 283 to reset and slide on the limiting support rod 281. At the same time, it causes the cover plate 284 to reset and adhere to the square plate 28, thereby locking the filtered impurities in the inner cavity of the filter cover 293, preventing impurities from falling into the filter pipe 21 and causing great obstruction to the cleaning work.

[0035] As one implementation method in this embodiment, such as Figure 1 , Figure 5 As shown, the workpiece moving mechanism 3 includes a synchronous electric cylinder 31, which is fixedly installed on the top of the normalizing furnace body 12. A furnace door 32 is fixedly installed on the telescopic end of the synchronous electric cylinder 31. A support frame 33 is fixedly installed on the left side of the furnace door 32. A support rod 34 is fixedly installed on the inner wall of the support frame 33 near the bottom. A heat insulation plate 35 is fixedly installed on the left side of the support frame 33. Before normalizing the workpiece, the synchronous electric cylinder 31 is controlled to extend, which drives the furnace door 32 to move to the right. The universal joint bushing workpiece is then placed on the top of the support rod 34. Then, the synchronous electric cylinder 31 is controlled to reset, transferring the workpiece into the inner cavity of the normalizing furnace body 12. After the workpiece is normalized, the synchronous electric cylinder 31 is controlled to extend, which can bring the workpiece out, realizing the function of automatically putting in or taking out the workpiece, increasing the safety of the operator. When the synchronous electric cylinder 31 extends, the heat insulation plate 35 can close the opening of the normalizing furnace body 12, reducing the heat consumption inside the normalizing furnace body 12.

[0036] Working principle: In use, first control the synchronous electric cylinder 31 to extend, driving the furnace door 32 to move to the right. Then, place the universal joint bushing workpiece on the top of the support rod 34. Then control the synchronous electric cylinder 31 to reset, transferring the workpiece to the inner cavity of the normalizing furnace body 12. Next, control the gas heating device body 11 to work, heating the workpiece inside the normalizing furnace body 12. The gas source pipe is pre-connected to the inlet pipe 23. When the gas heating device body 11 is working, the gas used flows through the inner cavity of the filter pipe 21. During the gas flow, the gas can be filtered by the filter cover 293. After the workpiece is normalized, control the synchronous electric cylinder 31 to extend, which can bring the workpiece out, and then the workpiece can be removed from the top of the support rod 34.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
