Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment technology, and more specifically, to a heat treatment equipment for shaft parts. Background Technology

[0002] Shaft parts are basic components widely used in the machinery industry. Their performance directly affects the overall operational stability and reliability of mechanical equipment. Heat treatment, as a key process to improve the performance of shaft parts, can effectively improve the microstructure of shaft parts and enhance their mechanical properties such as strength, hardness, and toughness.

[0003] Heat treatment of shaft parts is typically performed on specialized heat treatment equipment. However, traditional equipment for shaft parts has several shortcomings. Firstly, the heating methods usually employ resistance wire heating or gas heating, which struggles to achieve uniform and rapid heating of the shaft parts, leading to uneven heating of the internal structure and affecting the quality of the heat treatment. For example, when heating long shaft parts, the varying distances between the heating element and different parts of the part can cause inconsistent heating temperatures at both ends and in the middle, resulting in uneven overall performance of the part. Secondly, existing heat treatment equipment often requires manual handling using clamping devices to hold and transport shaft parts to the heat treatment equipment. This process requires personnel to approach the heat treatment area, where the high temperature poses a risk of burns, further complicating the heat treatment operation. Therefore, we propose a heat treatment device for shaft parts. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figures 1-4This utility model provides a technical solution: a heat treatment device for shaft parts, including two symmetrical guide rails 1 on the left and right. A first servo motor 11 is fixedly installed at one end of the guide rail 1. A lead screw 12 is fixedly installed at the end of the output shaft of the first servo motor 11. A slider 13 is threadedly connected to the lead screw 12. The slider 13 is slidably connected to the corresponding guide rail 1. A support rod 14 is fixedly installed at the end of the slider 13. A support plate 15 is fixedly installed at the end of the support rod 14. This allows the slider 13 to make precise linear movements along the guide rail 1 under the drive of the first servo motor 11. This provides an adjustable position basis for the support rod 14 and support plate 15 installed at the end of the slider 13, so as to flexibly adapt to the clamping requirements of shaft parts of different lengths.

[0028] Specifically, a second servo motor 16 is fixedly installed on the back of the support plate 15. The output shaft of the second servo motor 16 is detachably connected to an end plate 162. Two symmetrical horizontal plates 17 are fixedly installed on the front of the end plate 162. A cylinder 18 is fixedly installed on the horizontal plate 17. A clamping plate 181 is fixedly installed at the end of the telescopic shaft of the cylinder 18, so that the end plate 162 can rotate stably under the drive of the second servo motor 16. In this way, the shaft parts clamped by the cylinder 18 and the clamping plate 181 installed on the horizontal plate 17 on the front of the end plate 162 can achieve reverse rotation at a certain angle during the heat treatment process, ensuring that the shaft parts are heated evenly.

[0029] In this embodiment, an outer support cylinder 3 is provided between the two end plates 162. An electromagnetic heating coil 30 is fixedly installed on the inner annular side of the outer support cylinder 3. The center of the electromagnetic heating coil 30 and the center of the end plate 162 are located on the same horizontal axis. Both horizontal ends of the electromagnetic heating coil 30 are connected to the outside world, so that the electromagnetic heating coil 30 can perform efficient electromagnetic induction heating on the shaft parts located on its central axis. During the heating process, the heat can be evenly applied to the surface of the shaft parts and conducted to the inside, effectively improving the heating effect and heat treatment quality of the shaft parts.

[0030] Specifically, the ends of the two guide rails 1 that are close to each other are fixedly connected, and a fixing seat 31 is fixedly installed on the outer annular side of the outer support cylinder 3. The fixing seat 31 is fixedly installed on the front side of the end plate of the two guide rails 1 that are close to each other, so that the outer support cylinder 3 and the guide rails 1 form a stable integral structure. This not only ensures the stability of the electromagnetic heating coil 30 inside the outer support cylinder 3 during operation, but also ensures that the relative positions of the shaft parts remain unchanged throughout the heat treatment process, which is conducive to improving the reliability of equipment operation.

[0031] Furthermore, a groove 10 is provided inside the guide rail 1 along the length of the guide rail 1, and the slider 13 is located inside the groove 10 and slidably connected to the groove 10; the cross-section of both the slider 13 and the groove 10 is T-shaped, and the size of the slider 13 is adapted to the size of the groove 10, so that the slider 13 slides more smoothly on the guide rail 1, and can effectively prevent the slider 13 from detaching from the guide rail 1 during the movement. This structural design enhances the stability and reliability of the entire transmission system and provides a guarantee for the precise operation of the heat treatment equipment for shaft parts.

[0032] In addition, a fixed plate 161 is fixedly installed at the end of the output shaft of the second servo motor 16, and the end plate 162 is fixedly installed on the side of the fixed plate 161 by multiple fastening bolts, which facilitates the fixed installation and disassembly operations.

[0033] It is worth noting that support frames 2 are fixedly installed on the rear sides of the two guide rails 1, and two symmetrical support beams 20 are fixedly installed on the rear sides of the support frames 2. The support beams 20 are fixedly installed on the external frame, so that the entire shaft part heat treatment equipment can be stably installed in the working area. The support frames 2 and the support beams 20 provide a reliable support foundation for the equipment, ensuring that the equipment will not shake or shift during operation, thus ensuring the accuracy and stability of the heat treatment operation.

[0034] Finally, it should be noted that the first servo motor 11, the second servo motor 16, the cylinder 18, and the electromagnetic heating coil 30 of this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0035] When using the heat treatment equipment for shaft parts of this utility model, first place one end of the shaft part between the clamping plates 181 of the two end plates 162 on one side, and start the cylinder 18. The extension shaft of the cylinder 18 extends to drive the clamping plates 181 to firmly clamp one end of the part.

[0036] After clamping, the electromagnetic heating coil 30 is activated, and then the first servo motor 11 on the side of the clamping shaft part is activated. The first servo motor 11 drives the lead screw 12 to rotate, causing the slider 13 to slide smoothly in the slide groove 10 of the guide rail 1. This further drives the end plate 162 and the clamped shaft part to move towards the electromagnetic heating coil 30. As the shaft part is inserted into the electromagnetic heating coil 30, the inserted part is heated sequentially. When necessary, the second servo motor 16 can be activated. The second servo motor 16 drives the end plate 162 and the shaft part to rotate in opposite directions within a specified range of less than 270 degrees to ensure uniform heating.

[0037] After one end of the shaft part is heat-treated, the cylinder 18 at the other end is used to clamp the heat-treated end of the shaft part. The cylinder 18 on the untreated part of the shaft part is released, and the first servo motor 11 on the other side works to drive the untreated end of the shaft part into the electromagnetic heating coil 30 for heat treatment. After all heat treatment is completed, the shaft part is removed.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
