[0028] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.

[0029] In the embodiments of this application, the valve body can be regarded as tubular.

[0030] This application discloses a high-frequency heat treatment apparatus for a steering gear valve body. (Refer to...) Figure 1The high-frequency heat treatment equipment for steering gear valve bodies includes a feeding assembly 1, a conveying assembly 2, a heating assembly 3, a drilling and milling assembly 4, a discharging assembly 5, a polishing assembly 6, and a rotating table 7.

[0031] like Figure 1 and Figure 2 As shown, the feeding assembly 1 includes a feeding turntable 11 and a feeding track 12. The feeding turntable 11 is located at one end of the feeding track 12. The feeding turntable 11 is used to feed the valve body to the feeding track 12, and the feeding track 12 is used to transport the valve body to the end away from the feeding turntable 11. The feeding turntable 11 can initially store the valve body and adjust the posture of the valve body so that the valve body is in a vertical state, so that the valve body enters the starting end of the feeding track 12 one by one. The feeding track 12 can guide and transport the valve body, transporting the valve body from the feeding turntable 11 to the end away from the feeding turntable 11 so that the valve body can be heat treated later.

[0032] For example, in the embodiments of this application, the feeding turntable 11 includes, but is not limited to, an RT-150 feeder or a PA-300 feeder, and the feeding track 12 includes, but is not limited to, a YGP-DSZSA47-6.5 track or a DEPRAG-1522 track.

[0033] like Figure 1 and Figure 3 As shown, the conveying component 2 is located on one side of the feeding component 1 and is used to receive the valve body on the feeding track 12 and convey the valve body. The conveying component 2 can connect various processing equipment, ensure the transfer of the valve body between various processing equipment, improve the processing efficiency of the valve body, and improve the problem that the valve body needs to be manually transferred between different equipment multiple times by the operator during quenching heat treatment.

[0034] In this embodiment, the conveying assembly 2 includes a first slide rail 21, a connecting plate 22, a clamp 23, and a push rod 24. The first slide rail 21 is fixedly connected to any horizontal plane, and one end of the first slide rail 21 is disposed opposite to the feeding track 12. One side of the connecting plate 22 is fixedly connected to the movable end of the first slide rail 21. The connecting plate 22 is used to move synchronously with the movable end of the first slide rail 21. The push rod 24 is fixedly connected to the fixed end of the clamp 23 and the connecting plate 22. The push rod 24 is used to drive the clamp 23 to move relative to the connecting plate 22 to change the position of the clamp 23. The clamp 23 is used to clamp the valve body.

[0035] For example, the first slide rail 21 includes, but is not limited to, a belt-driven double pulley system or a linear slide rail; the connecting plate 22 is specifically an aluminum alloy plate or an iron alloy plate, and the connecting plate 22 is horizontally arranged; the clamp 23 includes, but is not limited to, a pneumatic clamp or an electric clamp; and the push rod 24 includes, but is not limited to, a hydraulic cylinder or a pneumatic cylinder, and the push rod 24 is vertically arranged. Taking the first slide rail 21 as a belt-driven double pulley system as an example, the belt of the first slide rail 21 is fixedly connected to the connecting plate 22. The first slide rail 21 is driven by a motor to rotate the pulley, thereby driving the belt to move, which in turn drives the connecting plate 22, the clamp 23, and the push rod 24 to move synchronously in the horizontal direction. The connecting plate 22 provides stable installation conditions for the push rod 24 and the clamp 23, ensuring the synchronous movement of the clamp 23 and the push rod 24. The push rod 24 can drive the clamp 23 to move relative to the connecting plate 22, thereby changing the position of the clamp 23 and enabling the clamp 23 to move in the vertical direction, thereby driving the valve body to move in the vertical direction, thus matching multiple processing positions of the valve body. The clamp 23 can hold the valve body. Under the action of the first slide rail 21 and the push rod 24, the clamp 23 can drive the valve body to move in the vertical and horizontal directions, adapting to various conveying needs and improving the flexibility of valve body processing.

[0036] It should be noted that there are several clamps 23 and push rods 24, and the spacing between the clamps 23 is the same, so as to form several positions for conveying the valve body.

[0037] like Figure 4 and Figure 5 As shown, the heating component 3 is disposed on one side of the conveying component 2 and is disposed opposite to the conveying component 2. It is used to perform heat treatment on the valve body conveyed by the conveying component 2. The heating component 3 can heat the valve body to change the hardness and toughness of the valve body so that the valve body meets the subsequent processing requirements. In this embodiment of the application, the heating component 3 includes a first heater 31 and a second heater 32. The first heater 31 can heat the inner hole of the hanging pin, and the second heater 32 can heat the outer wall of the valve body.

[0038] For example, the first heater 31 includes a first induction coil 311 and a first power supply 312. The first induction coil 311 is, but is not limited to, a copper coil or a wound coil, and the first power supply 312 is a ZN-20G-F2 power supply or an EasyHeat power supply. An 8310 power supply or an IGBT ultra-high frequency 60kW power supply is used. The first induction coil 311 is fixedly installed on one side of the conveying assembly 2. The first induction coil 311 is horizontally arranged, and the end of the first induction coil 311 near the conveying assembly 2 is bent upward. The bent part of the first induction coil 311 is used to extend into the valve body to heat the valve body by induction heating. The first power supply 312 is electrically connected to the first induction coil 311. The first power supply 312 is used to provide electrical energy to the first induction coil 311 so that the first induction coil 311 can generate an alternating magnetic field. The first induction coil 311 can extend into the conveyed valve body. The first power supply 312 provides electrical energy to the first induction coil 311, so that the first induction coil 311 generates an alternating magnetic field. The first induction coil 311 heats the valve body by induction heating through the generated alternating magnetic field, thereby achieving heat treatment of the valve body and reducing manual intervention.

[0039] It should be noted that the heating assembly 3 also includes a rotator 33, please refer to [reference needed]. Figure 6 The rotator 33 is disposed between the first heater 31 and the conveying assembly 2. The rotator 33 includes a first driving member 331, a base 332, and a support 333 with a slide rail in the vertical direction. The support 333 is vertically arranged. The first driving member 331 and the base 332 are fixedly connected to the slide rail through a horizontally arranged metal plate or rubber plate. The fixed end of the first driving member 331 is fixedly connected to the metal plate or rubber plate. The base 332 is rotatably connected to the metal plate or rubber plate. The first driving member 331 is a motor, and the base 332 is a metal frustum. A through hole for the first induction coil 311 to pass through is opened at the central axis of the base 332. A through hole for the first induction coil 311 to pass through is opened at the corresponding position of the metal plate or rubber plate. The base 332 and the first driving member 331 are connected by a transmission gear set. The base 332 is used to support the valve body, and the first driving member 331 is used to drive the base 332 to rotate around the axis, so that the valve body can rotate during the heating process, achieve uniform heating, and improve the heating quality of the valve body.

[0040] like Figure 5 As shown, the second heater 32 includes a second induction coil 321 and a second power supply 322. The second induction coil 321 is fixedly disposed on one side of the conveying assembly 2. The second induction coil 321 is used to fit against the outer wall of the valve body to heat the valve body by induction heating. The second power supply 322 is electrically connected to the second induction coil 321 and is used to provide electrical energy to the second induction coil 321 so that the second induction coil 321 can generate an alternating magnetic field.

[0041] For example, the second induction coil 321 may include, but is not limited to, a copper coil or a wound coil, and the second power supply 322 may be a ZN-20G-F2 power supply, an EasyHeat 8310 power supply, or an IGBT high-frequency 30kW power supply. The side of the second induction coil 321 near the conveying assembly 2 may be in contact with the outer wall of the valve body. The second power supply 322 may provide electrical energy to the second induction coil 321, causing the second induction coil 321 to generate an alternating magnetic field. The second induction coil 321 heats the valve body at the contacted part through the alternating magnetic field, thereby heating part of the valve body and making the heating of the valve body more flexible.

[0042] like Figure 7 As shown, the drilling and milling assembly 4 includes a second slide rail 41, a third slide rail 42, and a drilling power head 43. The second slide rail 41 is disposed on any plane, and the movable end of the second slide rail 41 is fixedly connected to the fixed end of the third slide rail 42. The second slide rail 41 is used to drive the third slide rail 42 to move in the vertical direction. The movable end of the third slide rail 42 is fixedly connected to the fixed end of the drilling power head 43. The third slide rail 42 is used to drive the drilling power head 43 to move in the horizontal direction. The drilling power head 43 is used to drill and mill the valve body.

[0043] For example, the second slide rail 41 and the third slide rail 42 are, but are not limited to, KK60 linear slide rails or FPBS40 electric slide rails, and the drilling power head 43 is, but is not limited to, SV2P-3075 drilling machine or RTCS5 drilling machine. The second slide rail 41 can drive the third slide rail 42 and the drilling power head 43 to move in the vertical direction and adjust the position of the drilling power head 43, while the third slide rail 42 can drive the drilling power head 43 to move in the horizontal direction and realize the feed of the drilling power head 43. This allows the drilling power head 43 to perform drilling and milling on different positions of the valve body, improve the processing efficiency of the valve body, shorten the processing cycle of the valve body, and improve the problem that the valve body needs to be manually transferred between different equipment multiple times by the operator during quenching heat treatment.

[0044] Optionally, several drilling and milling assemblies 4 are provided, and several drilling and milling assemblies 4 are arranged side by side on one side of the conveying assembly 2 to form several workstations for machining the valve body.

[0045] Optionally, the drilling head 43 can also rotate the valve body to increase the machining area. Specifically, the clamp 23 holds and moves the valve body until it is aligned with the corresponding drilling head 43, driving the drilling head 43 to partially drill into the non-middle section of the valve body, without completely penetrating it. The clamp 23 then releases the valve body and continues to rotate the movable end of the drilling head 43, causing the valve body to rotate around its axis until it is upside down. Finally, the clamp 23 holds the valve body, allowing the drilling head 43 to complete the drilling and milling of the valve body. At this point, the valve body is upside down, completing the process. The flipping of the valve body increases the number of positions for processing the valve body, optimizing the processing technology. For some complex valve body structures, such as valve bodies with multiple holes, grooves or special shapes, there is no need for complex multi-axis linkage or special fixtures 23, reducing the dependence on additional equipment. Optionally, the third slide rail 42 extends on the side near the output end of the drilling power head 43 and forms a part with a hole through which the output end of the drilling power head 43 passes. When the drilling power head 43 is eccentrically inserted into the flipped valve body, the drilling power head 43 undergoes elastic deformation or vibration, and the third slide rail 42 can restrict the drilling power head 43 by abutting.

[0046] like Figure 8 As shown, the polishing assembly 6 includes a support frame 61, a guide rail 62, a horizontal plate 63, a second drive member 64, a third drive member 65, and a cylindrical diamond grinding head 66. The support frame 61 is vertically arranged and located on the side of the conveying assembly 2 near the drilling and milling assembly 4. The guide rail 62 is vertically arranged on the side of the support frame 61 near the conveying assembly 2. The horizontal plate 63 is horizontally arranged and fixedly connected to the movable end of the guide rail 62. A through hole is provided on the horizontal plate 63. The second drive member 64 is slidably connected to the horizontal plate 63, and the output end of the second drive member 64 passes through the through hole. The cylindrical diamond grinding head 66 is fixedly connected to the output end of the second driving member 64. The second driving member 64 is used to drive the cylindrical diamond grinding head 66 to move relative to the valve body so that the cylindrical diamond grinding head 66 grinds the valve body. The fixed end of the third driving member 65 is fixedly connected to the horizontal plate 63, and the movable end of the third driving member 65 is fixedly connected to the second driving member 64. The third driving member 65 is used to drive the second driving member 64 to move so as to drive the cylindrical diamond grinding head 66 to move relative to the valve body so as to change the position of the cylindrical diamond grinding head 66 grinding the valve body.

[0047] In this embodiment, the support frame 61 can be equipped with a guide rail 62, which can drive the horizontal plate 63 to move in the vertical direction, thereby driving the second driving member 64 to move in the vertical direction, and then driving the columnar diamond grinding head 66 to move in the vertical direction relative to the valve body, so that the columnar diamond grinding head 66 can be inserted into the valve body. At this time, the second driving member 64 is driven by the third driving member 65 to move, which can change the position of the second driving member 64 and the columnar diamond grinding head 66, thereby grinding the valve body.

[0048] For example, the second drive member 64 can be a motor or a hydraulic cylinder, and the third drive member 65 can be a pneumatic cylinder. The third drive member 65 is used to drive the second drive member 64 to move closer to or away from the conveying assembly 2. When the second drive member 64 is a motor, it can drive the cylindrical diamond grinding head 66 to rotate, thereby grinding the valve body and removing burrs from the valve body, which is suitable for grinding different types of valve bodies. When the second drive member 64 is a hydraulic cylinder, it can drive the cylindrical diamond grinding head 66 to reciprocate to grind the valve body, which is suitable for grinding valve bodies with high hardness and long length.

[0049] Optionally, in this embodiment, the polishing assembly 6 further includes an inner hole polisher 67, which is movably mounted on the support frame 61. The inner hole polisher 67 is used to polish the holes on the side wall of the valve body. The inner hole polisher 67 is pushed by, but not limited to, a cylinder or a hydraulic cylinder, so that it can move relative to the support frame 61, thereby approaching or moving away from the valve body, and thus polishing the holes on the side wall of the valve body.

[0050] It should be noted that, in this embodiment of the application, the two clamping teeth of the clamp 23 are parallel when fully open, forming a straight opening.

[0051] like Figure 9 As shown, the rotary table 7 is disposed between the conveying assembly 2 and the drilling and milling assembly 4. The rotary table 7 is used to carry the valve body conveyed by the conveying assembly 2, and changes the position of the valve body relative to the drilling and milling assembly 4 by rotating, thereby changing the processing position of the valve body. The rotary table 7 can receive the valve body sent by the conveying assembly 2, and drive the valve body to rotate by rotating around its own rotation axis, thereby changing the position of the valve body relative to the drilling and milling assembly 4, thereby changing the processing position of the valve body and realizing multi-directional processing of the valve body. Optionally, several rotary tables 7 are provided, and several rotary tables 7 are disposed between the conveying assembly 2 and the drilling and milling assembly 4, with several rotary tables 7 corresponding one-to-one with several drilling and milling assemblies 4.

[0052] For example, the rotating table 7 may include, but is not limited to, a hollow rotating platform or a hollow servo turntable, for water to flow through the central through-hole to cool the valve body or flush away drill cuttings.

[0053] For example, a rotating platform 7 can be placed between the second heater 32 and the conveying assembly 2 to support the valve body, ensuring the stability of the valve body position when the second heater 32 heats the valve body, and driving the valve body to rotate through its own rotation to change the position of the second heater 32 heating the valve body.

[0054] For example, a rotating table 7 can be disposed between the polishing assembly 6 and the conveying assembly 2. The rotating table 7 is disposed opposite to the hole of the horizontal plate 63 to support the valve body, ensuring the stability of the valve body position when the columnar diamond grinding head 66 and the inner hole polisher 67 polish the valve body. The rotating table 7 also drives the valve body to rotate by its own rotation, thereby changing the position of the columnar diamond grinding head 66 and the inner hole polisher 67 polishing the valve body.

[0055] like Figure 10 As shown, the unloading component 5 is located on the side of the conveying component 2 away from the loading component 1, and includes an unloading track 51 and a receiving turntable 52. The unloading track 51 is used to transport the valve body conveyed by the conveying component 2 to the receiving turntable 52, and the receiving turntable 52 is used to accommodate the processed valve body. Specifically, the unloading component 5 can transport the processed valve body conveyed by the conveying component 2 to the receiving turntable 52, and the receiving turntable 52 accommodates the processed valve body, which facilitates subsequent packaging, transportation or warehousing operations and improves collection efficiency.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
