Description

Technical Field

[0001] This utility model relates to the field of carburizing and quenching technology, and in particular to a fixing fixture for carburizing and quenching a slider. Background Technology

[0002] Carburizing and quenching is a composite heat treatment process that increases the carbon concentration on the surface of a workpiece through high-temperature carburizing, followed by rapid cooling to form a high-hardness, high-wear-resistant martensitic structure. It is mainly used to improve the surface properties of low-carbon steel or alloy steel parts. When performing this operation, a fixing fixture is required to hold the workpiece in place.

[0003] Patent CN219747729U discloses a combined multifunctional clamp. It includes a clamp base with two sets of opposing clamping components on its top. Each clamping component includes a fixed seat, a telescopic cylinder, a housing, a slider, a screw, and a chuck. The fixed seat is fixedly connected to the top of the clamp base, the telescopic cylinder is axially and horizontally fixedly connected to the fixed seat, and the telescopic end of the cylinder is fixedly connected to the housing. The housing has a groove on its side for the slider to slide. Using this patent, the two sets of clamping components work together to clamp and fix the workpiece. However, when using the aforementioned prior art, if the workpiece has different shapes, after clamping, stress will concentrate on four clamping points. When clamping thin-walled, brittle, or irregularly shaped workpieces, uneven clamping force distribution can easily lead to cracking.

[0004] Therefore, there is a need to provide a fixed fixture for carburizing and quenching a slider that adapts to the workpiece. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents mentioned above, which cause stress concentration at four clamping points when using workpieces of different shapes, and which easily lead to uneven clamping force distribution and cracking when clamping thin-walled, brittle or irregularly shaped workpieces, this utility model provides a fixed fixture for carburizing and quenching a slider that adapts to workpieces.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a fixed fixture for carburizing and quenching a slider, comprising a worktable and a fixed frame. The fixed frame is fixedly connected to the worktable. The fixture also includes a guide rod, a screw, a dual-axis motor, a sliding plate, a mounting plate, a fixed seat, clamping rods, and elastic elements. The guide rod is fixedly connected to the fixed frame. The dual-axis motor is mounted on the worktable. Screws are mounted on both output shafts of the dual-axis motor via couplings. Sliding plates are threaded onto the screws. Two identical sliding plates are slidably mounted on the guide rod. A mounting plate is fixedly connected between the two sliding plates on the guide rod and the screw, which are located on the same horizontal line. A fixed seat is fixedly connected to the mounting plate. Three clamping rods are slidably mounted on the fixed seat. Elastic elements are sleeved on the clamping rods, and both ends of the elastic elements are connected to the clamping rods and the fixed seat, respectively.

[0007] More preferably, it also includes an electric guide rail, an electric slider, a sliding frame, a push plate, a guide plate, a hopper, and a collection box. An electric guide rail is installed on the worktable, an electric slider is installed on the electric guide rail, a sliding frame is installed on the electric slider, a push plate is fixedly connected between two sliding frames, two guide plates are fixedly connected to the worktable, a hopper is fixedly connected to the worktable, and a collection box is slidably installed on the worktable.

[0008] More preferably, it also includes a fixing block, a lead screw, and a limiting plate. The fixing block is fixedly connected to the worktable, the lead screw is threaded onto the fixing block, and the limiting plate is fixedly connected to the lead screw.

[0009] More preferably, the clamping rod is equipped with a rubber pad.

[0010] More preferably, two limit brackets are fixedly connected to the worktable.

[0011] More preferably, each worktable has four mounting holes.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By starting the dual-axis motor, the two output shafts of the dual-axis motor drive the two screws to rotate. The screws drive the sliding plate and the mounting plate to move synchronously along the guide rod. The mounting plate drives the fixed seat and its upper components to move together, so that the workpiece pressing clamping rod moves outward to press the elastic element. The elastic element is compressed and quickly rebounds. The elastic element drives the clamping rod to move inward, so that the clamping rod adapts to the size and shape of the workpiece, thereby enabling the clamping of workpieces of different sizes and shapes.

[0013] 2. By activating two electric guide rails, the electric guide rails drive the electric slider to move, and the electric slider drives the sliding frame and push plate to move. This allows the processed workpiece to be automatically pushed to the guide plate, and then the workpiece slides along the guide plate into the hopper and finally falls into the collection box, thus achieving automated collection and speeding up work efficiency.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1: A fixing fixture for carburizing and quenching a slider, see reference. Figures 1-5 As shown, the device includes a worktable 1 and a fixed frame 2. The fixed frame 2 is welded to the middle of the worktable 1. It also includes a guide rod 3, a screw 4, a dual-axis motor 5, a sliding plate 6, a mounting plate 7, a fixed seat 8, clamping rods 9, and an elastic element 10. The guide rod 3 is welded to the rear of the fixed frame 2. The dual-axis motor 5 is bolted to the middle of the worktable 1. Screws 4 are mounted on the two output shafts of the dual-axis motor 5 via couplings. The screws 4 rotate on the fixed frame 2. Sliding plates 6 are threaded onto the screws 4. Two identical sliding plates 6 are slidably mounted on the guide rod 3. The mounting plate 7 is fixedly connected between the two sliding plates 6 on the guide rod 3 and the screw 4, which are located on the same horizontal line. A fixed seat 8 is fixedly connected to the outside of the mounting plate 7. Three clamping rods 9 are slidably mounted on the fixed seat 8 at even intervals. An elastic element 10 is sleeved on the clamping rods 9. The two ends of the elastic element 10 are connected to the clamping rods 9 and the fixed seat 8, respectively.

[0022] See Figures 1-3 and Figure 5 As shown, the end of the clamping rod 9 is provided with a rubber pad.

[0023] See Figures 1-5 As shown, the right side of the workbench 1 is symmetrically connected with a limit frame, which limits the sliding frame 13.

[0024] See Figures 1-5 As shown, each workbench 1 has four mounting holes.

[0025] When using this device, place the workpiece on the worktable 1, then start the dual-axis motor 5. The two output shafts of the dual-axis motor 5 drive the two screws 4 to rotate. The screws 4 drive the sliding plate 6 and the mounting plate 7 to move synchronously along the guide rod 3. The mounting plate 7 drives the fixed seat 8 and its upper components to move together, causing the workpiece to squeeze the clamping rod 9 outward. The clamping rod 9 then squeezes the elastic element 10, which is compressed and quickly rebounds. The elastic element 10 drives the clamping rod 9 inward, thereby making the clamping rod 9 adapt to the size and shape of the workpiece, so as to clamp workpieces of different sizes and specifications. At the same time, the rubber pad on the clamping rod 9 increases the friction between the clamping rod 9 and the workpiece. After clamping, carburizing and quenching can be performed.

[0026] Example 2: Based on Example 1, refer to Figure 1 and Figure 4 As shown, it also includes an electric guide rail 11, an electric slider 12, a sliding frame 13, a push plate 14, a guide plate 15, a hopper 16, and a collection box 17. The left and right sides of the worktable 1 are both equipped with electric guide rails 11 by bolt connection. Electric sliders 12 are installed on the electric guide rails 11, and sliding frames 13 are installed on the electric sliders 12. A push plate 14 is welded between the two sliding frames 13. The push plate 14 is located above the worktable 1. Two guide plates 15 are fixedly connected to the upper part of the worktable 1. The sliding frames 13 slide on the corresponding guide plates 15. A hopper 16 is fixedly connected to the left side of the worktable 1. A collection box 17 is slidably installed on the left side of the worktable 1. The collection box 17 is located below the hopper 16.

[0027] After the carburizing and quenching process is completed, the two electric guide rails 11 are activated. The electric guide rails 11 drive the electric slider 12 to move, and the electric slider 12 drives the sliding frame 13 and the push plate 14 to move. This allows the processed workpiece to be automatically pushed to the guide plate 15. The workpiece then slides along the guide plate 15 into the unloading hopper 16 and finally falls into the collection box 17, thus achieving automated collection and speeding up the work. The limit frame constrains the stroke of the sliding frame 13 to ensure accurate pushing action.

[0028] See Figure 1 and Figure 5 As shown, it also includes a fixing block 18, a lead screw 19 and a limiting plate 20. The fixing block 18 is fixedly connected to the worktable 1, and the lead screw 19 is threadedly provided on the fixing block 18. The end of the lead screw 19 is fixedly connected to the limiting plate 20.

[0029] When the workpiece is fixed, the lead screw 19 on the rotating fixing block 18 drives the limiting plate 20 to move, thereby axially positioning the workpiece and placing it in the carburizing and quenching zone to ensure its quality.
