Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat treatment technology for thin-walled parts, and in particular to a positioning device for thin-walled quenched parts. Background Technology
[0002] Thin-walled parts, such as sealing contact rings, undergo heat treatment during processing. Heat treatment can eliminate internal stress in the workpiece (heat treatment releases internal stress in the material through heating, holding, and cooling processes, preventing cracks or deformation caused by stress concentration), refine grains (annealing or isothermal quenching processes can significantly refine grains, improve the plasticity and toughness of the material, and optimize mechanical properties), improve machinability (annealing can reduce material hardness, facilitating subsequent processing (such as stamping and turning) and reducing processing stress), and enhance wear resistance (induction hardening or carburizing processes can significantly improve surface hardness and extend the service life of thin-walled parts).
[0003] However, during the high-temperature quenching process of heat treatment, thin-walled parts will deform due to the interaction of structural stress and thermal stress, which will increase the scrap rate of the sealing contact ring. Utility Model Content
[0004] The purpose of this utility model is to provide a positioning device for thin-walled quenched parts, which solves the problem that the sealing contact ring will deform due to the interaction of structural stress and thermal stress during the high-temperature quenching process of thin-walled parts, thereby increasing the scrap rate of the sealing contact ring.
[0005] To achieve the above objectives, this utility model provides a positioning device for thin-walled quenched parts, including a top plate and a mounting device. The mounting device is installed on the top plate. It also includes a limiting device, which includes a connecting column, a triangular support, an outer limiting ring, a guide assembly, and a locking assembly. The connecting column is fixedly installed on the top plate, the triangular support is slidably installed on the connecting column, the outer limiting ring is installed on the top plate through the guide assembly, and the locking assembly is installed on the connecting column.
[0006] The guide assembly includes a mounting pad and a guide rod. The mounting pad is fixedly mounted on the top plate. The guide rod is fixedly mounted on the mounting pad and slides with the outer limiting ring. The guide rod is close to the connecting column.
[0007] The locking assembly includes a first locking ring, a second locking ring, a connecting rod, and a moving component. The first locking ring is slidably mounted on the guide rod; the second locking ring is slidably mounted on the connecting post via the moving component; and both ends of the connecting rod are fixedly connected to the first locking ring and the second locking ring, respectively.
[0008] The movable component includes a threaded sleeve and a mounting block. The threaded sleeve is threadedly engaged with the connecting column and is also rotatably engaged with the second locking ring. The mounting block is fixedly mounted on the threaded sleeve.
[0009] The mounting device includes a mounting column and a hanging ring. The mounting column is fixedly installed on the top plate, and the hanging ring is fixedly installed on the mounting column.
[0010] This utility model discloses a positioning device for thin-walled quenched parts. In use, the triangular support and the outer limiting ring are respectively fitted onto the connecting column and the guide rod. Then, the sealing contact ring to be quenched is slid between the triangular support and the outer limiting ring. Next, the first locking ring is aligned with the guide rod, and the threaded sleeve is screwed onto the connecting column, causing the second locking ring and the first locking ring to move upwards, thus locking and securing the outer limiting ring and the triangular support. Then, through the hanging column and the hanging ring, with the activation of external hoisting equipment, the top plate along with the sealing contact ring is hoisted into the furnace for quenching. During the process, the triangular support supports the inner side of the sealing contact ring, while the outer limiting ring restricts the outer circle of the sealing contact ring, thereby preventing deformation of the sealing contact ring during quenching and ensuring product quality.

Detailed Implementation
[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0017] The embodiment of this application is as follows:
[0018] Please see Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of a positioning device for a thin-walled quenched part according to this utility model. Figure 2 This is a schematic diagram of the mounting device of this utility model. Figure 3 This is a schematic diagram of the connection between the second locking ring and the threaded sleeve of this utility model.
[0019] This utility model provides a positioning device for thin-walled quenched parts: including a top plate 101 and a mounting device, and also including a limiting device. The limiting device includes a connecting column 102, a triangular support 103, an outer limiting ring 104, a guide assembly, and a locking assembly. The guide assembly includes a mounting pad 105 and a guide rod 106. The locking assembly includes a first locking ring 107, a second locking ring 108, a connecting rod 109, and a moving component. The moving component includes a threaded sleeve 110 and a mounting block 111. The mounting device includes a mounting column 112 and a hanging ring 113. The aforementioned solution solves the problem that during the high-temperature quenching process of thin-walled parts, the interaction of structural stress and thermal stress causes deformation of the sealing contact ring, resulting in an increased scrap rate of the sealing contact ring.
[0020] In this embodiment, the inner side of the sealing contact ring is supported by the triangular support 103, while the outer limiting ring 104 restricts the outer circle of the sealing contact ring, thereby preventing the sealing contact ring from deforming during the quenching process.
[0021] The connecting post 102 is fixedly mounted on the top plate 101, the triangular support 103 is slidably mounted on the connecting post 102, the outer limiting ring 104 is mounted on the top plate 101 via the guide assembly, the locking assembly is mounted on the connecting post 102, the connecting post 102 is welded to the bottom of the top plate 101, and the connecting post 102 is threaded. The triangular support 103 has a prismatic structure with rounded edges. The number of outer limiting rings 104 can be increased or decreased according to usage requirements. The guide assembly facilitates the movement of the outer limiting ring 104. By mounting the triangular support 103 and the outer limiting ring 104 on the top plate 101, and installing the sealing contact ring between the triangular support 103 and the outer limiting ring 104, and locking it with the locking assembly, the triangular support 103 supports the inner side of the sealing contact ring, while the outer limiting ring 104 restricts the outer circle of the sealing contact ring, thereby preventing deformation of the sealing contact ring during quenching and ensuring product quality.
[0022] Secondly, the mounting pad 105 is fixedly mounted on the top plate 101; the guide rod 106 is fixedly mounted on the mounting pad 105 and slides with the outer limiting ring 104. The guide rod 106 is close to the connecting post 102. The mounting pad 105 is fixed to the top plate 101 by screws. There are multiple sets of mounting pads 105, which are distributed in a ring at the bottom of the top plate 101. The guide rod 106 is welded to the mounting pad 105. Through the cooperation of the mounting pad 105 and the guide rod 106, the outer limiting ring 104 can slide on the top plate 101.
[0023] Furthermore, the first locking ring 107 is slidably mounted on the guide rod 106; the second locking ring 108 is slidably mounted on the connecting post 102 via the moving member; both ends of the connecting rod 109 are fixedly connected to the first locking ring 107 and the second locking ring 108 respectively, the connecting rod 109 is circumferentially welded to the outside of the second locking ring 108, the first locking ring 107 is welded to the connecting rod 109, the interval angle between the first locking rings 107 is equal to the interval angle of the guide rod 106, the moving member drives the second locking ring 108 to move upward, so that the connecting rod 109 drives the first locking ring 107 to move upward with the second locking ring 108, and locks the triangular support 103 and the outer limiting ring 104.
[0024] Furthermore, the threaded sleeve 110 is threadedly engaged with the connecting post 102. The threaded sleeve 110 has an inverted T-shaped cross-section and a thread on its inner side. The mounting block 111 is annularly disposed at the bottom of the threaded sleeve 110. By rotating the mounting block 111, the mounting block 111 drives the threaded sleeve 110 to rotate. This allows the threaded sleeve 110 to move on the connecting post 102 during rotation due to its threaded engagement with the connecting post 102. Since the threaded sleeve 110 and the second locking ring 108 are rotatedly engaged with the threaded sleeve 110, the second locking ring 108 can move synchronously with the threaded sleeve 110.
[0025] Finally, the mounting column 112 is fixedly installed on the top plate 101; the hanging ring 113 is fixedly installed on the mounting column 112. The mounting column 112 is welded to the top of the top plate 101, and the hanging ring 113 is welded to the top of the mounting column 112. Through the cooperation of the hanging ring 113 and the mounting column 112, the top plate 101 is easy to be hoisted.
[0026] In this embodiment, during use, the triangular support 103 and the outer limiting ring 104 are respectively fitted onto the connecting column 102 and the guide rod 106. Then, the sealing contact ring to be quenched is slid between the triangular support 103 and the outer limiting ring 104. Subsequently, the first locking ring 107 is aligned with the guide rod 106, and the threaded sleeve 110 is screwed onto the connecting column 102, causing the second locking ring 108 and the first locking ring 107 to move upward, and the outer limiting ring 104 and the triangular support 103 to abut and lock. Then, through the hanging column 112 and the hanging ring 113, with the start of the external hoisting equipment, the top plate 101 along with the sealing contact ring is hoisted into the furnace for quenching. During the process, the triangular support 103 supports the inner side of the sealing contact ring, while the outer limiting ring 104 restricts the outer circle of the sealing contact ring, thereby preventing the sealing contact ring from deforming during the quenching process and ensuring the quality of the product.
[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
