This utility model discloses a tempering device for engineering machinery parts, including a furnace body and a furnace cover disposed on one side of the furnace body. A base is fixedly connected to the bottom of the furnace body, and a driving structure is disposed on one side of the furnace body. A bottom plate is fixedly connected to one side of the furnace cover and inside the furnace body. A protrusion is integrally formed on the top of the bottom plate, and a groove is formed on the top of the bottom plate. A through hole is formed on the top of the protrusion. Driven by a servo motor, a threaded rod rotates. The threaded rod is supported by a bearing seat, causing the threaded rod to rotate, which in turn drives a threaded sleeve to rotate, thereby moving a support plate. The support plate, through a sliding groove, moves a connecting plate, which in turn moves the furnace cover on top of it. This allows the bottom plate to extend out of the furnace cavity, facilitating the loading and unloading of materials. The spacing between the protrusion and the groove creates a gap at the bottom of the parts, making it easy to remove them using a clamping tool.

Description

Technical Field

[0001] This utility model belongs to the field of mechanical parts processing technology, and in particular relates to a tempering device suitable for engineering machinery parts. Background Technology

[0002] Tempering is a metal heat treatment process in which a quenched workpiece is reheated to a suitable temperature below the lower critical temperature Ac1 (the temperature at which pearlite begins to transform into austenite during heating), held at that temperature for a period of time, and then cooled in air, water, oil, or other media. Alternatively, it involves heating a quenched alloy workpiece to a suitable temperature, holding it at that temperature for a certain period of time, and then cooling it slowly or rapidly. It is generally used to reduce or eliminate internal stress in quenched steel parts, or to reduce their hardness and strength in order to improve their ductility or toughness.

[0003] The tempering method for parts involves placing them in a tempering furnace, requiring tools to pick them up and insert them into the furnace. After tempering, tools are needed to reach into the furnace to remove them. This method increases the inconvenience and difficulty of picking up and putting down materials. Utility Model Content

[0004] The purpose of this invention is to provide a tempering device suitable for engineering machinery parts, which facilitates material handling and disposal, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A tempering device for engineering machinery parts includes a furnace body and a furnace cover disposed on one side of the furnace body. A base is fixedly connected to the bottom of the furnace body. A driving structure is disposed on one side of the furnace body. A bottom plate is fixedly connected to one side of the furnace cover and inside the furnace body. A protrusion is integrally formed on the top of the bottom plate. A groove is opened on the top of the bottom plate. A through hole is opened on the top of the protrusion. The bottom of the bottom plate is slidably connected to the bottom of the inner cavity of the furnace body. A connecting plate is fixedly connected to the bottom of the furnace cover.

[0006] The drive structure includes a servo motor fixedly connected to one side of the furnace cover. A threaded rod is fixedly connected to the output end of the servo motor. The surface of the threaded rod is rotatably connected to the furnace cover through a bearing seat. A threaded sleeve is threadedly connected to the surface of the threaded rod. A support plate is fixedly connected to the surface of the threaded sleeve. A sliding groove adapted to slide with the support plate is opened on the inner surface of the base. The bottom of the support plate is fixedly connected to the end of the connecting plate away from the furnace cover.

[0007] Preferably, limit holes are provided at the four corners of the corresponding end faces of the furnace body and the furnace cover, and limit posts that are compatible with the limit holes are fixedly connected at the four corners of the end face of the furnace cover near the furnace body.

[0008] Preferably, a sliding groove is fixedly connected to the bottom of the furnace cavity, and a slide rail is provided at the bottom of the bottom plate, with the inner surface of the slide rail slidably connected to the surface of the sliding groove.

[0009] Preferably, there are multiple grooves and through holes, and the protrusions and grooves are arranged at intervals.

[0010] 1. The beneficial effects of this utility model are as follows: This utility model uses a servo motor to drive a threaded rod to rotate. The threaded rod is supported by a bearing seat, which in turn drives the threaded sleeve to rotate, thereby moving the support plate. The support plate moves the connecting plate through the limiting sliding of the slide groove, which in turn moves the furnace cover on top of it. This allows the bottom plate to extend out of the furnace cavity, facilitating the loading and unloading of materials. The alternating arrangement of the protrusions and grooves creates a gap at the bottom of the parts, making it easy to remove them using a clamping tool. The combination of the grooves and through holes allows the bottom of the parts to be heated. By setting the above structure, the loading and unloading of materials can be made more convenient.

[0011] 2. This utility model limits the movement of the furnace cover by setting a limiting post inserted into the limiting hole.

[0012] 3. This utility model supports and limits the movement of the base plate by setting the inner surface of the slide rail to slide in a sliding connection with the surface of the sliding groove.

[0013] 4. By setting protrusions and grooves at intervals, the bottom of the part is heated, and a gap is left at the bottom to facilitate the insertion of a clamping tool into the groove to remove the part. Attached Figure Description

[0020] In the following description, embodiments of the present invention applicable to tempering devices for engineering machinery parts will be described with reference to the accompanying drawings.

[0021] Example:

[0022] Figure 1-3 This invention discloses a tempering device for engineering machinery parts, comprising a furnace body 1, wherein the furnace body 1 is an existing mature device for tempering parts, and a furnace cover 2 disposed on one side of the furnace body 1. A base 3 is fixedly connected to the bottom of the furnace body 1, a drive structure 4 is disposed on one side of the furnace body 1, a bottom plate 5 is fixedly connected to one side of the furnace cover 2 and located inside the furnace body 1, a protrusion 6 is integrally formed on the top of the bottom plate 5, a groove 7 is opened on the top of the bottom plate 5, a through hole 8 is opened on the top of the protrusion 6, the bottom of the bottom plate 5 is slidably connected to the bottom of the inner cavity of the furnace body 1, and a connecting plate 9 is fixedly connected to the bottom of the furnace cover 2.

[0023] The drive structure 4 includes a servo motor 41 fixedly connected to one side of the furnace cover 2. A threaded rod 42 is fixedly connected to the output end of the servo motor 41. The surface of the threaded rod 42 is rotatably connected to the furnace cover 2 via a bearing seat 13. A threaded sleeve 43 is threadedly connected to the surface of the threaded rod 42. A support plate 44 is fixedly connected to the surface of the threaded sleeve 43. A sliding groove 45 adapted to slide on the inner surface of the base 3 is provided, and the bottom of the support plate 44 is fixedly connected to the end of the connecting plate 9 away from the furnace cover 2. Driven by the servo motor 41, the threaded rod 42 is rotated. The threaded rod 42 rotates via a shaft. The support 13 rotates, causing the threaded rod 42 to drive the threaded sleeve 43 to rotate, thereby moving the support plate 44. The support plate 44 moves the connecting plate 9 through the limiting sliding of the slide groove 45, which in turn moves the furnace cover 2 on top of it, so that the bottom plate 5 extends out of the furnace cavity of the furnace body 1, thereby allowing material to be picked up and put down. At the same time, the interval between the protrusion 6 and the groove 7 creates a gap at the bottom of the part, making it easy to remove with a clamping tool. Meanwhile, the matching arrangement of the groove 7 and the through hole 8 allows the bottom of the part to be heated. By setting the above structure, the purpose of picking up and putting down materials can be achieved more conveniently.

[0024] Limiting holes 10 are provided at the four corners of the corresponding end faces of the furnace body 1 and the furnace cover 2. Limiting posts 11 that are adapted to the limiting holes 10 are fixedly connected to the four corners of the end face of the furnace cover 2 near the furnace body 1. By setting the limiting posts 11 to be inserted into the limiting holes 10, the movement of the furnace cover 2 is limited. Preferably, the furnace cover 2 is provided with ventilation holes (not shown), which maintain the pressure inside the furnace body 1 at the same level as the external atmospheric pressure.

[0025] A sliding groove 14 is fixedly connected to the bottom of the inner cavity of the furnace body 1, and a slide rail 15 is provided at the bottom of the bottom plate 5. The inner surface of the slide rail 15 is slidably connected to the surface of the sliding groove 14, which supports and limits the movement of the bottom plate 5.

[0026] In this embodiment, there are multiple grooves 7 and through holes 8. The protrusions 6 and grooves 7 are arranged at intervals. By setting the protrusions 6 and grooves 7 at intervals, the bottom of the part is heated, and the gap at the bottom is also convenient for the clamping tool to remove the part.

[0027] Working principle: When this utility model is in use, the servo motor 41 is started, and the threaded rod 42 is driven to rotate by the servo motor 41. The threaded rod 42 is supported by the bearing seat 13, which causes the threaded sleeve 43 to rotate, thereby causing the support plate 44 to move. The support plate 44 moves the connecting plate 9 through the limiting sliding of the sliding groove 45, and then moves the furnace cover 2 on top of it. The bottom plate 5 slides between the bottom slide rail 15 and the sliding groove 14, and then extends out of the furnace cavity of the furnace body 1, so as to pick up and put in materials. At the same time, the interval between the protrusion 6 and the groove 7 creates a gap at the bottom of the part, which is convenient to remove with a clamping tool. At the same time, the groove 7 and the through hole 8 are designed to heat the bottom of the part. The movement of the furnace cover 2 is limited by the limiting post 11 inserted into the limiting hole 10.
