Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, specifically a gear quenching treatment device. Background Technology

[0002] In gear production, in order to enhance the strength, hardness and other properties of gears, quenching is often required. Quenching is a heat treatment process in which steel is heated to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), held at that temperature for a period of time to make it fully or partially austenitized, and then rapidly cooled to below Ms (or isothermally near Ms) at a cooling rate greater than the critical cooling rate to carry out the martensitic (or bainitic) transformation.

[0003] The existing gear quenching equipment has the following drawbacks during use: the gears need to be placed on the quenching platform manually, and after the high-frequency coil has finished heating, the heated gears need to be quickly placed into the quenching liquid manually. The entire process is done manually, which is time-consuming and labor-intensive, affects the quenching efficiency, and poses safety hazards. Therefore, there is room for improvement. Utility Model Content

[0008] In a preferred embodiment, the present invention may be further configured such that the first driving component includes a first threaded rod rotatably mounted between opposing columns and a first motor fixed on one side column with its shaft fixedly connected to the end of the first threaded rod.

[0009] In a preferred embodiment, the present invention can be further configured such that: a threaded hole is provided in the middle of the movable seat, the first threaded rod passes through the threaded hole, and the two mesh with each other.

[0010] In a preferred embodiment, the present invention can be further configured such that: a groove is formed on the outer side of the column, and the second driving component includes a second threaded rod rotatably mounted on the inner wall of the groove and a second motor fixed to the top of the column with its shaft fixedly connected to the end of the second threaded rod.

[0011] In a preferred embodiment, the present invention can be further configured such that: the movable seat includes a support fixed to the end of a threaded sleeve with one end fitted into a groove and the other end extending out of the groove; the second threaded rod passes through the threaded sleeve, and the two mesh with each other.

[0012] In a preferred embodiment, the present invention can be further configured such that the stirring component includes a third motor installed at the bottom of the cylinder with its shaft extending into the inner cavity of the cylinder, and stirring rollers fixed in a ring array on the shaft of the third motor.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, columns are fixed on both sides of the conveyor belt, and a crossbar is installed between the opposing columns. A movable seat is slidably installed on the crossbar, and a clamping component is installed on the movable seat. At the same time, the movable seat is moved by a first driving component to install the quenching mechanism on one side column. With the above configuration, the clamping component clamps the gear from the conveyor belt. Then, the first driving component drives the movable seat to move above the quenching mechanism, and the clamping seat then drives the gear to move down into the quenching mechanism for quenching. After completion, the gear is placed back on the conveyor belt. The gear moves automatically throughout the process without manual intervention, which effectively improves the quenching efficiency and avoids the safety hazards that exist in the process of manually moving the gear.

[0015] 2. In this utility model, a movable seat is set on one side column to fix the cylinder body. The movable seat moves up and down through a second driving component, which in turn drives the cylinder body to move up and down. A high-frequency heating coil is installed on the inner wall of the cylinder body, and a water inlet pipe and a water outlet pipe are installed on one side of the cylinder body. When the gear moves to the top of the cylinder body, the first driving component drives the movable seat to move upward, which in turn drives the cylinder body to move upward, so that the gear is located in the middle of the high-frequency heating coil. At this time, the high-frequency heating coil heats the gear. After heating is completed, the cylinder body continues to move upward, so that the heated gear is immersed in the quenching liquid in the cylinder body to complete the quenching. The whole process is automated. In addition, a stirring component that extends into the cylinder body is installed at the bottom of the cylinder body. The stirring component stirs the quenching liquid in the inner cavity of the cylinder body to ensure the stable and consistent temperature of the quenching liquid, which effectively improves the quenching effect of the gear.

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example 1

[0024] Combination Figures 1-3 As shown, this embodiment provides a gear quenching treatment device, including: a main body 100 and a quenching mechanism 200.

[0025] The main structure 100 includes a conveyor belt 110, uprights 120 symmetrically arranged on both sides of the conveyor belt 110, crossbars 130 on both sides opposite the uprights 120, a movable seat 140 slidably arranged on the crossbars 130, a clamping member 150 installed on the movable seat 140, and a first driving member 160 installed between the opposite uprights 120 and passing through the movable seat 140.

[0026] The conveyor belt 110 is used to transport gears that need to be quenched, increasing the degree of automation. The column 120 is used to install the crossbar 130 to ensure the stability of the crossbar 130. The crossbar 130 is used to install the movable seat 140 and limit the movement of the movable seat 140. The movable seat 140 is used to install the clamping component 150 and drive the clamping component 150 to move.

[0027] The clamping component 150 is used to clamp and fix the gear on the conveyor belt 110. It includes an electric telescopic rod 151 symmetrically fixed on both sides of the movable seat 140 and an inner support clamping device 152 fixed at the bottom of the electric telescopic rod 151. The electric telescopic rod 151 is used to install the inner support clamping device 152 and drive the inner support clamping device 152 to move up and down. The inner support clamping device 152 is existing technology and its implementation principle is also existing. It will not be described in detail here. It is used to clamp the gear to facilitate the subsequent movement of the gear.

[0028] The first driving component 160 is used to drive the movable seat 140 to move. It includes a first threaded rod 161 rotatably installed between the opposing columns 120 and a first motor 162 fixed on one side column 120 with its shaft fixedly connected to the end of the first threaded rod 161. A threaded hole 141 is opened in the middle of the movable seat 140. The first threaded rod 161 passes through the threaded hole 141 and the two mesh with each other. When the first motor 162 is started, it drives the first threaded rod 161 to rotate. The first threaded rod 161 rotates in the threaded hole 141, driving the entire movable seat 140 to move.

[0029] The quenching mechanism 200 is used to quench gears and includes a movable seat 210 movably mounted on a column 120 on one side, a second drive member 220 installed in the inner cavity of the column 120 and passing through the movable seat 210, a cylinder 230 fixed to one side of the movable seat 210, a high-frequency heating coil 240 installed on the inner wall of the cylinder 230, a water inlet pipe 250 installed on one side of the cylinder 230, a drain pipe 260 installed on one side of the cylinder 230, and a stirring member 270 installed at the bottom of the cylinder 230 and extending into the inner cavity of the cylinder 230.

[0030] A groove 121 is formed on the outer side of one of the columns 120. The second driving member 220 includes a second threaded rod 221 rotatably mounted on the inner wall of the groove 121 and a second motor 222 fixed to the top of the column 120 and whose shaft is fixedly connected to the end of the second threaded rod 221. Meanwhile, the movable seat 210 includes a threaded sleeve 211 with one end fitted into the groove 121 and the other end extending out of the groove 121, and a support 212 fixed to the end of the threaded sleeve 211. The second threaded rod 221 passes through the threaded sleeve 211 and the two mesh with each other. When the second motor 222 is started, it drives the second threaded rod 221 to rotate. The rotation of the second threaded rod 221 drives the threaded sleeve 211 to move, and then drives the cylinder 230 to move up and down through the support 212.

[0031] The outer side of the cylinder 230 is fixedly connected to the support 212. The high-frequency quenching device is installed on the inner wall of the cylinder 230 to heat the gears and facilitate subsequent heat treatment.

[0032] The inlet pipe 250 is used to feed quenching fluid into the inner cavity of the cylinder 230, and the drain pipe 260 is used to discharge the quenching fluid from the inner cavity of the cylinder 230.

[0033] The stirring component 270 includes a third motor 271 installed at the bottom of the cylinder 230 with its shaft extending into the inner cavity of the cylinder 230, and stirring rollers 272 fixed in a ring array on the shaft of the third motor 271. When the third motor 271 is started, it drives the stirring rollers to rotate, stirring the quenching liquid in the inner cavity of the cylinder 230, so as to ensure the stable and consistent temperature of the quenching liquid and effectively improve the quenching effect of the gears.

[0034] The working principle and usage process of this utility model are as follows: During use, the electric telescopic rod 151 moves downwards, causing the inner support clamping device 152 to move downwards and clamp the gear from the conveyor belt 110. Then, the electric telescopic rod retracts, causing the gear to move upwards. Simultaneously, the first motor 162 starts, causing the first threaded rod 161 to rotate. The rotation of the first threaded rod 161 causes the movable seat 140 to move, moving the gear above the cylinder 230. At the same time, when the second motor 222 starts, it causes the second threaded rod 221 to rotate. The rotation of the second threaded rod 221 causes the second threaded sleeve 211 to move upwards. The upward movement of the second threaded sleeve 211 is driven by the support 212. The cylinder 230 moves upward, positioning the gear in the middle of the high-frequency heating coil 240. At this time, the high-frequency heating coil 240 is activated to heat the gear. After the gear is heated, the cylinder 230 continues to move upward, immersing the heated gear in the quenching liquid. Simultaneously, the third motor 271 is activated, driving the stirring roller 272 to rotate and stir the quenching liquid, ensuring a stable and consistent temperature. After quenching, the cylinder 230 moves downward, and the moving seat 140 moves the gear above the conveyor belt 110. The electric telescopic rod 151 descends, placing the gear on the conveyor belt 110. The inner support clamping device 152 is released, completing the entire process.
