It connects the differential and the wheels, and transmits power from the differential to the wheels, thereby driving the vehicle forward or backward. Half shaft heat treatment refers to the heating and cooling of half shaft materials to improve their mechanical properties, especially to improve their strength, hardness and wear resistance. Heat treatment is an important process step in manufacturing high-quality half shafts, and is essential to ensure the reliability and durability of half shafts under various working conditions. High-frequency quenching is a commonly used heat treatment method that uses high-frequency current to generate heat on the metal surface, and then rapidly cools it to achieve hardening of the metal surface.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0035] Reference Figures 1 to 4 In an embodiment of the present invention, a semi-axle heat treatment processing device comprises: a fixing frame 1, a cooling pool 5 for quickly cooling the heated semi-axle is fixedly arranged at one end of the fixing frame 1, a straightening device 6 for supporting the semi-axle to keep it in a vertical state is arranged on the cooling pool 5, an upper fixing member 7 for fixing the top of the semi-axle is arranged on the straightening device 6, a lower fixing member 8 for fixing the bottom of the semi-axle is arranged on the straightening device 6, a positioning member 9 for positioning the semi-axle is arranged on the upper fixing member 7, so that the axis of the semi-axle is located at the exact center of the upper fixing member 7 and the lower fixing member 8, and a feeding device 10 for guiding the semi-axle into the positioning member 9 and pushing the semi-axle to move downward into between the upper fixing member 7 and the lower fixing member 8 is arranged on the fixing frame 1;

[0036] The upper fixing member 7 includes a fixing plate 71 fixedly arranged with the straightening device 6, the fixing plate 71 is C-shaped, and two groups of fixing plates 71 are arranged, which are symmetrically distributed on both sides of the positioning member 9, and a linking member 72 is rotatably arranged on the inner side of each group of fixing plates 71, and the two groups of linking members 72 are distributed at ninety degrees, and a top column 73 is fixedly connected to the bottom end of each group of linking members 72, and each group of top columns 73 is composed of a quarter of a cylinder and a cone, and a telescopic rod 74 is arranged on each group of linking members 72, and the telescopic rod 74 is a quarter of a circle, and the telescopic rod 74 is composed of an inner tube and an outer tube, and the inner tube is arranged inside the outer tube and slidably plugged with the outer tube, and one end of the outer tube of the telescopic rod 74 is fixedly connected to the inner side of the fixing plate 71, and one end of the inner tube of the telescopic rod 74 is fixedly arranged with the linking member 72, and a spring 75 is sleeved on the outer side of the telescopic rod 74, and the two ends of the spring 75 are respectively fixedly connected to the linking member 72 and the fixing plate 71;

[0037] The feeding device 10 guides the semi-shaft therein into the positioning member 9 in a vertical state, and pushes the semi-shaft to move downward. During the movement, the bottom end of the semi-shaft gradually contacts the top end of the linkage member 72, and pushes the linkage member 72 to rotate downward, and stretches the spring 75 until the semi-shaft passes through the gap of the linkage member 72 and is inserted into the straightening device 6. The bottom end of the semi-shaft passing through the straightening device 6 abuts against the top column 73 in the lower fixing member 8, and pushes the linkage member 72 in the lower fixing member 8 to rotate downward, so that the distance between the upper fixing member 7 and the top column 73 on the lower fixing member 8 is greater than the length of the semi-shaft. At this time, the semi-shaft does not contact the upper fixing member 7. Under the restoring force of the spring 75 in the fixed member 7, the linkage member 72 is driven to reset, and the feeding device 10 gradually withdraws from the upper fixed member 7. During this process, the lower fixed member 8 gradually returns to a horizontal state and pushes the semi-axle thereon upward. Due to the gravity of the semi-axle, the lower fixed member 8 gradually returns to a horizontal state at a slower speed than the upper fixed member 7. When the upper fixed member 7 returns to a horizontal state, the semi-axle contacts the top column 73 of the upper fixed member 7 and abuts against the semi-axle. At this time, the upper and lower ends of the semi-axle respectively abut against the top columns 73 on the upper fixed member 7 and the lower fixed member 8, and the semi-axle is fixed between the upper fixed member 7 and the lower fixed member 8.

[0038] Reference Figures 4 to 5 The lower fixing member 8 also includes a fixing plate 71, a linkage member 72, a top column 73, a telescopic rod 74 and a spring 75, wherein the top column 73 in the lower fixing member 8 is fixedly arranged at the top of the linkage member 72, a connecting ear 711 is fixedly connected to the inner side of the fixing plate 71, and the linkage member 72 includes an inner rod 721 rotatably connected to the connecting ear 711, a spring 722 is fixedly connected to one side of the inner rod 721, and an outer rod 723 is fixedly connected to the other end of the spring 722, a slot 724 is provided through the top of the outer rod 723, the inner rod 721 is slidably plugged into the slot 724, the outer rod 723 is fixedly arranged with the top column 73, the top of the inner rod 721 is fixedly connected to the telescopic rod 74, and one end of the spring 75 is fixedly connected to the inner rod 721. After one group of half-axles is heated, the next group of half-axles is also pushed between the upper fixing member 7 and the lower fixing member 8. When the next group of half-axles enters, they will abut against the half-axles that have been heated and push the half-axles that have been heated downward. During the movement, the connecting member 72 in the lower fixing member 8 is pushed to rotate downward, and the spring 75 is stretched until the gap of the connecting member 72 allows the half-axles to pass through. When most of the half-axles that have been heated are pushed out of the lower fixing member 8, due to the gravity of the half-axles, the half-axles quickly fall into the cooling pool 5 for cooling, and the connecting member 72 in the lower fixing member 8 returns to a horizontal state due to the rapid fall of the half-axles. Then, as the next group of half-axles continues to move downward, the half-axles contact the connecting member 72 in the lower fixing member 8.

[0039] The above solution is adopted: the movement of the outer rod 723 pushes the spring three 722 to be compressed, so that when the connecting member 72 rotates, a larger passage is formed, allowing the half shaft to pass smoothly, ensuring that the half shaft is not obstructed during the entire processing process, avoiding possible jamming or damage.

[0040] Reference Figures 2 to 3 The straightening device 6 includes a mounting plate 61 fixedly arranged with the cooling pool 5, a connecting rod 62 is slidably inserted at the side end of the mounting plate 61, the connecting rod 62 is T-shaped, one end of the connecting rod 62 passes through the mounting plate 61, and is fixedly connected with a straightening plate 63, the straightening plate 63 is C-shaped, and the inlet and outlet at the upper and lower ends of the straightening plate 63 are conical surfaces, a ball is embedded in the inner wall of the straightening plate 63, and the ball is rotatably connected to the straightening plate 63, a spring 2 64 is sleeved on the outer side of the connecting rod 62, and the spring 2 64 is arranged at On the outside of the mounting plate 61, two groups of straightening devices 6 are provided, which are symmetrically distributed at the top of the cooling pool 5. The spacing between the two groups of straightening devices 6 and the straightening contact areas of the half-shaft is smaller than the diameter of the half-shaft. When the half-shaft moves from top to bottom and is inserted between the two groups of straightening devices 6, the half-shaft abuts against the conical surface of the straightening plate 63 and pushes the two groups of straightening plates 63 to move outward, causing the spring 2 64 to stretch and deform, so that the spacing between the two groups of straightening devices 6 and the straightening contact areas of the half-shaft is the same as the diameter of the half-shaft, allowing the half-shaft to pass through.

[0041] The above solution is adopted: through two symmetrically distributed straightening plates 63 and their conical surface design, it can ensure that the half-shaft is always in a vertical state when inserted into the cooling pool 5, which not only improves the stability of the half-shaft when entering the cooling pool 5, but also ensures the uniformity and effectiveness of the cooling process.

[0042] Reference Figure 6The positioning member 9 includes a mounting frame 91 fixedly connected to the inner side of the fixing plate 71. The mounting frame 91 is composed of a group of C-shaped connecting plates and two groups of straight plates. One end of the straight plate is fixedly connected to the C-shaped connecting plate, and the other end is fixedly connected to the inner wall of the fixing plate 71. The side end of the C-shaped connecting plate in the mounting frame 91 is slidably plugged with a fixing rod 92. The fixing rod 92 is T-shaped. Two groups of fixing rods 92 are arranged and evenly distributed in the mounting frame 91. One end of the fixing rod 92 passes through the mounting frame 91 and is fixedly connected with a positioning plate 94. The positioning plate 94 is C-shaped, and the top of the positioning plate 94 is an inclined surface. A spring four 93 is sleeved on the outer side of the fixing rod 92. The spring The four 93 are arranged on the outside of the mounting frame 91, and there are two groups of positioning members 9, which are symmetrically distributed on the inner sides of the two groups of fixing plates 71, and the spacing between the two groups of positioning plates 94 is the same as the diameter of the bottom end of the semi-axle. When the feeding device 10 introduces the semi-axle inside it into the positioning member 9 in a vertical state, the bottom end of the semi-axle contacts the inclined surface at the top end of the positioning plate 94, and is inserted between the two groups of positioning plates 94 under the guidance of the inclined surface, so that the semi-axle is moved to the center position of the upper fixing member 7 and the lower fixing member 8. As the semi-axle is gradually pushed in, the part larger than the bottom end diameter pushes the two groups of positioning plates 94 to move outward, and stretches and deforms the spring, so that the spacing between the two groups of positioning plates 94 allows the semi-axle to pass.

[0043] The above solution is adopted: through the C-shaped positioning plate 94 and the inclined surface design, the bottom end of the half shaft is effectively guided during the downward movement, ensuring that the axis of the half shaft is accurately located in the center of the upper fixing member 7 and the lower fixing member 8, thereby ensuring the accuracy of subsequent processing.

[0044] Reference Figures 7 and 8 The feeding device 10 includes a material box 101 fixedly connected to the top of the fixed frame 1. The material box 101 is an inclined surface, so that the semi-axle in the material box 101 can roll in the material box 101. A material drop groove 102 is provided at the bottom of the lower end of the material box 101. The length of the material drop groove 102 is greater than half of the length of the semi-axle. When the semi-axle rolls to the material drop groove 102, the semi-axle part at the material drop groove 102 is greater than the semi-axle part not at the material drop groove 102, causing the semi-axle to become unbalanced and fall from the material drop groove 102. A baffle 103 is fixedly connected to the top of the material drop groove 102, and a baffle 2 104 is fixedly connected to the bottom of the material box 101. A feed rack 105 is fixedly connected to one side of the top of 101, and a hydraulic rod 106 is fixedly connected to the top of the feed rack 105. The output end of the hydraulic rod 106 passes through the feed rack 105. When the half-axle rolls to the blanking trough 102, the half-axle part at the blanking trough 102 is larger than the half-axle part not at the blanking trough 102, causing the half-axle to become unbalanced and rotate and fall from the blanking trough 102. When falling, the half-axle contacts baffle 1 103 and baffle 2 104 respectively during the rotation process, and under the restriction of baffle 1 103 and baffle 2 104, the half-axle becomes vertical and is inserted into the positioning member 9, and then the hydraulic rod 106 is started to push the half-axle to move downward.

[0045] By adopting the above solution: through the limiting effect of baffle 103 and baffle 2 104, the feeding device 10 can ensure that the half-shaft is in a vertical state when inserted into the positioning member 9. This design improves the accuracy and stability of the half-shaft positioning and facilitates the smooth progress of subsequent processing.

[0046] Reference Fig. 9 A lifting device 2 is provided on the fixed frame 1, and the lifting device 2 is provided with two groups, which are symmetrically distributed on both sides of the top of the fixed frame 1. The movable end of the lifting device 2 is fixedly connected to the lifting platform 3, and a heating device 4 for heating the half shaft is fixedly provided on the lifting platform 3. A heating coil 41 is fixedly provided at one end of the heating device 4, and a top opening ring 42 is fixedly provided at one end of the heating device 4 for pushing the straightening plate 63 to move to the side end when it abuts against the straightening plate 63. The top opening ring 42 is provided with two groups symmetrically distributed at the upper and lower ends of the heating coil 41. The diameter of the top opening ring 42 is smaller than the maximum diameter of the conical surface of the straightening plate 63. When the lifting device 2 drives the heating device 4 to move up and down, the top opening ring 42 abuts against the conical surface of the straightening plate 63, pushing the two groups of straightening plates 63 to move outward, so that the spring 2 64 stretches and deforms, so that the distance between the straightening contact area of ​​the two groups of straightening devices 6 and the half shaft is larger than the heating coil 41, so that the heating coil 41 can pass through.

[0047] For this purpose, in the present technical solution, the lifting device 2 is a linear drive, which is a mechanical device that converts rotational motion into linear motion. Its main components include a screw rod, a nut, a motor, a guide rail and a control system. The rotation of the motor is transmitted to the screw rod through a coupling, causing the screw rod to rotate, thereby pushing the nut to move along the thread of the screw rod. The heating device 4 is a high-frequency power supply, which is responsible for converting industrial frequency alternating current into high-frequency alternating current, and generating a high-frequency alternating magnetic field in the heating coil 41 through the high-frequency alternating current. When a metal workpiece is placed in this magnetic field, eddy currents will be generated inside the workpiece. These eddy currents will encounter resistance when flowing inside the metal workpiece, and will generate a large amount of heat, thereby rapidly increasing the temperature of the workpiece.

[0048] By adopting the above scheme: through the contact between the top opening ring 42 and the conical surface of the straightening plate 63, the straightening plate 63 can be pushed to move outward, so that the spring 2 64 stretches and deforms, thereby increasing the distance between the straightening device 6 and the half-axis, ensuring that the heating device 4 can pass through the straightening device 6 smoothly, avoiding interference between the heating coil 41 and the straightening plate 63, thereby ensuring the continuity and stability of the heating process.

[0049] The working principle of the present invention is as follows: when the half-shaft in the material box 101 rolls to the blanking groove 102, the half-shaft part at the blanking groove 102 is larger than the half-shaft part not at the blanking groove 102, causing the half-shaft to become unbalanced and rotate and fall from the blanking groove 102. When falling, the half-shaft contacts the baffle 1 103 and the baffle 2 104 respectively during the rotation process, and under the restriction of the baffle 1 103 and the baffle 2 104, the half-shaft becomes a vertical state and is inserted into the positioning member 9, and then the hydraulic rod 106 is started to push the half-shaft downward. When moving, the bottom end of the half-shaft contacts the inclined surface at the top of the positioning plate 94, and is inserted between the two sets of positioning plates 94 under the guidance of the inclined surface, so that the half-shaft is moved to the center position of the upper fixing member 7 and the lower fixing member 8. As the half-shaft is gradually The part larger than the bottom diameter pushes the two groups of positioning plates 94 to move outwards and stretches the spring so that the spacing between the two groups of positioning plates 94 allows the half shaft to pass through. Then, the bottom end of the half shaft gradually contacts the top of the linkage 72 and pushes the linkage 72 to rotate downwards and stretches the spring one 75 until the gap of the linkage 72 allows the half shaft to pass through. When the linkage 72 rotates, the outer rods 723 abut against each other, causing the outer rods 723 to move toward the fixed plate 71 and compress the spring three 722 so that the half shaft passes smoothly and is inserted into the straightening device 6. When the half shaft moves from top to bottom and is inserted between the two groups of straightening devices 6, the half shaft abuts against the conical surface of the straightening plate 63 and pushes the two groups of straightening plates 63 to move outwards, causing the spring two 64 to stretch and deform. The spacing between the straightening contact area of ​​the straightening device 6 and the half shaft is the same as the diameter of the half shaft, so that the half shaft can pass through. After that, the bottom end of the half shaft passing through the straightening device 6 abuts against the top column 73 in the lower fixing member 8, and pushes the linking member 72 in the lower fixing member 8 to rotate downward, so that the spacing between the upper fixing member 7 and the top column 73 on the lower fixing member 8 is greater than the length of the half shaft. At this time, the half shaft does not contact the upper fixing member 7. Under the restoring force of the spring 75 in the upper fixing member 7, the linking member 72 is driven to reset, and the feeding device 10 gradually withdraws from the upper fixing member 7. In this process, the lower fixing member 8 gradually returns to a horizontal state and pushes the half shaft on it upward. Due to the gravity of the half shaft, the speed at which the lower fixing member 8 gradually returns to a horizontal state is slower than that of the upper fixing member 7, so that the upper fixing member 7 is restored. When it returns to the horizontal state, the half shaft contacts the top column 73 of the upper fixing member 7 and abuts against the half shaft. At this time, the upper and lower ends of the half shaft abut against the top columns 73 on the upper fixing member 7 and the lower fixing member 8 respectively, and the half shaft is fixed between the upper fixing member 7 and the lower fixing member 8. Then the lifting device 2 is started to drive the heating device 4 to move up and down, and the heating device 4 is started to energize the heating coil 41 so that the heating coil 41 heats the half shaft. During the movement, the top opening ring 42 abuts against the conical surface of the straightening plate 63, pushing the two groups of straightening plates 63 to move outward, so that the spring 2 64 stretches and deforms, so that the spacing between the straightening contact areas of the two groups of straightening devices 6 and the half shaft is larger than the heating coil 41, so that the heating coil 41 can pass through and the half shaft is completely heated. After one group of half shafts is heated,The next set of half shafts is also pushed into between the upper fixing member 7 and the lower fixing member 8. When the next set of half shafts enters, they will abut against the half shafts that have been heated and push the half shafts that have been heated to move downward. During the movement, the linking member 72 in the lower fixing member 8 is pushed to rotate downward, and the spring 75 is stretched until the gap of the linking member 72 allows the half shaft to pass through. When most of the half shafts that have been heated are pushed out of the lower fixing member 8, due to the gravity of the half shafts, the half shafts quickly fall into the cooling pool 5 for cooling, and the linking member 72 in the lower fixing member 8 is restored due to the rapid fall of the half shaft. The upper and lower fixing members 7 and 8 are connected to each other by the linkage 72 and the spring 75, respectively, so that the position of the top column 73 can be automatically adjusted according to the size of the half shaft. The design of the linkage 72 and the telescopic rod 74 ensures that the half shaft can pass through the upper and lower fixing members 7 and 8 smoothly. The rotation of the linkage 72 and the action of the spring can adapt to half shafts of different diameters, thereby ensuring the versatility of the equipment for half shafts of different specifications. The cooperation of the straightening plate 63 and the spring 64 ensures that the half shaft always remains in a vertical state when entering the cooling pool 5. The conical surface design of the straightening plate 63 enables the half shaft to push the straightening plate 63 to move outward when inserted, so that the spacing between the straightening contact areas of the two sets of straightening devices 6 and the half shaft matches the diameter of the half shaft, ensuring the stable passage of the half shaft. The inclined surface design of the fixing rod 92 in the positioning member 9 and the positioning plate 94 ensures that the half shaft can be accurately guided to the center position when inserted between the upper fixing member 7 and the lower fixing member 8. The positioning plate 94 is guided by the spring 94 through the spring 9 3 can adapt to the half shafts of different diameters, ensuring the versatility of the equipment for half shafts of different specifications. The limiting effect of baffle 103 and baffle 204 in the feeding device 10 ensures that the half shaft is in a vertical state when inserted into the positioning member 9, improving the accuracy and stability of the half shaft positioning, which is conducive to the smooth progress of the subsequent processing process. The inclined design of the material box 101 and the cooperation of the hydraulic rod 106 realize the automatic feeding of the half shaft, reduce the need for manual intervention, improve production efficiency, and ensure the stability and accuracy of the feeding process.
