Description

Technical Field

[0001] The utility model relates to the technical field of mechanical assembly, and particularly relates to a high-frequency induction heating automatic press-fitting mechanism. Background Technique

[0002] In the mechanical industry, press-fitting plays an irreplaceable role in certain mechanical process flows. To ensure the stability of the mechanical device after press-fitting, a certain interference fit is required during production and manufacturing, and the method of hot sleeve is used for press-fitting during the interference fit press-fitting process. The hot sleeve utilizes the principle of thermal expansion and contraction, heating and expanding the containing part and then cooling it, and the containing part shrinks to wrap the contained part.

[0003] The publication number is: CN207521995U, and the disclosed "high-frequency induction heating press-fitting device includes a conveying and positioning mechanism and a heating mechanism supporting the conveying and positioning mechanism; the conveying and positioning mechanism includes a workbench, a transverse guide rail, a feeding cylinder, a positioning seat and a positioning block. The transverse guide rail is fixedly installed on the workbench. The extending end of the feeding cylinder is connected to the positioning seat, and the bottom of the positioning seat is in mating connection with the transverse guide rail. The positioning block is located on the side of the transverse guide rail and is perpendicularly installed on the workbench with the transverse guide rail; the heating mechanism includes a linear guide rail and a high-frequency heating head, and the high-frequency heating head is installed at the extending end of the linear guide rail through a clamping seat";

[0004] When in use, there are still certain drawbacks. After press-fitting, the workpiece needs to be manually placed into the positioning seat, and the workpiece is moved to different workstations for heating and press-fitting through the cylinder. Then, after press-fitting, the workpiece is manually removed. And the workpiece heating requires a certain amount of time. During this period, the workers are idle, and the installation position of the workpiece needs to be manually adjusted, which is not convenient for automatically positioning the workpiece, resulting in a low press-fitting rate of the workpiece. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-frequency induction heating automatic press-fitting mechanism to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A high-frequency induction heating automatic press-fitting mechanism includes:

[0008] A bottom plate, on the upper surface of which a stamping mechanism is symmetrically and fixedly installed;

[0009] A moving component, fixedly installed on the upper surface of the bottom plate. The moving component includes a slide rail, and symmetrically sliding connections are arranged on the outer side of the slide rail with sliding seats. At both ends inside the slide rail on the upper surface of the bottom plate, a first cylinder fixedly connected to the sliding seat is symmetrically and fixedly installed;

[0010] A support assembly is disposed inside the slide block. The support assembly includes a support rod fixedly installed inside the slide block. A placement plate is fixedly installed on the upper end of the support rod. Multiple sliding grooves are formed at equal angles on one side surface of the placement plate. A slider is slidably connected inside the sliding groove.

[0011] Multiple clamping components are fixedly mounted above the slider.

[0012] Furthermore, a linear motor is fixedly installed on the upper surface of the base plate, and a clamp is fixedly installed on the slide surface of the linear motor, with a heating coil fixedly clamped inside the clamp.

[0013] Furthermore, a second cylinder is symmetrically fixedly installed on the upper surface of the base plate, a push plate is fixedly installed at the output end of the second cylinder, a third cylinder is symmetrically fixedly installed at both ends of the upper surface of the base plate, a discharge plate is fixedly installed at the output end of the third cylinder, and a discharge bin is symmetrically fixedly installed on one side of the upper surface of the base plate.

[0014] Furthermore, a rotating plate is rotatably connected to the upper outer side of the support rod, and multiple arc-shaped grooves are formed at equal angles on one side surface of the rotating plate. One end of the slider passes through the groove and is slidably connected to the corresponding arc-shaped groove.

[0015] Preferably, a gear ring is fixedly installed on the other side surface of the rotating plate, a motor is fixedly installed inside the slide, and a first gear that meshes with the gear ring is fixedly installed at the output end of the motor.

[0016] Furthermore, the clamping assembly includes:

[0017] Multiple connectors are fixedly installed on the upper surface of multiple sliders;

[0018] The rotating block is rotatably connected inside the connecting seat;

[0019] The clamp is movably fitted onto one end of the rotating block.

[0020] Preferably, a second gear is fixedly installed at the other end of the rotating block through the connecting seat, an electric push rod is fixedly installed on one side surface of the connecting seat, a rack that meshes with the second gear is fixedly installed at the output end of the electric push rod, and a bolt is detachably connected between the rotating block and the clamping plate.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By extending the No. 2 cylinder, the slide is fixed, improving the stability during pressing. After pressing, the No. 3 cylinder retracts, causing the unloading plate to move and pull the workpiece above the placement plate into the unloading bin for automatic unloading. This allows one workpiece to be pressed while another is heated, enabling alternating operations. After pressing, the workpiece is automatically removed, replacing manual unloading, accelerating the unloading speed, and improving pressing efficiency.

[0023] 2. The motor operates, causing the rotating plate to rotate. At the same time, the arc-shaped groove rotates synchronously, pushing the slider to move inside the groove. Multiple clamping components clamp the workpiece placed above the placement plate, fixing the workpiece in place. The detachable connection between the rotating block and the clamping plate via bolts allows the clamping plate to be easily disassembled and replaced. By replacing the clamping plate with one of the corresponding shape, the worker can place the workpiece and roughly adjust its position. When the clamping plate is used, it can fit against the surface of the workpiece and automatically position it. This facilitates automatic calibration of the workpiece's position during clamping after it is placed on the placement plate, replacing manual placement and positioning, and speeding up the loading and unloading of workpieces, thereby increasing the pressing rate of the workpiece. After pressing, the electric push rod retracts, causing the rotating block to drive the clamping plate to flip downwards, so that the clamping plate does not obstruct the workpiece, making it easier for the unloading plate to push the workpiece off the surface of the placement plate.

[0031] 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.

[0032] Please see Figure 1-6 In this embodiment of the present invention, a high-frequency induction heating automatic pressing mechanism includes a base plate 1. A stamping mechanism 101 is symmetrically fixedly mounted on the upper surface of the base plate 1. A linear motor 102 is fixedly mounted on the upper surface of the base plate 1. A clamping seat 103 is fixedly mounted on the slide surface of the linear motor 102. A heating coil 104 is fixedly clamped inside the clamping seat 103. When the linear motor 102 rotates, it drives the heating coil 104 to move, facilitating the heating of the workpiece. A moving component 2 is fixedly mounted on the upper surface of the base plate 1. The moving component 2 includes a slide rail 201. A slide block 202 is symmetrically slidably connected to the outside. A first cylinder 203, which is fixedly connected to the slide block 202, is symmetrically fixedly installed on the upper surface of the base plate 1 at both ends inside the slide rail 201. A support assembly 3 is located inside the slide block 202. The support assembly 3 includes a support rod 301 fixedly installed inside the slide block 202. A placement plate 303 is fixedly installed on the upper end of the support rod 301. Multiple sliding grooves 304 are opened at equal angles on one side surface of the placement plate 303. A slider 306 is slidably connected inside the sliding groove 304. Multiple clamping assemblies 4 are fixedly installed above the slider 306.

[0033] Specifically, the stamping mechanism 101 is used to press the workpiece. By alternately extending and retracting two No. 1 cylinders 203, it drives two support components 3 to move to different stations, and alternately heats and presses the workpieces at different stations.

[0034] Example 1

[0035] like Figure 1-3As shown, in this embodiment, a second cylinder 204 is symmetrically fixedly installed on the upper surface of the base plate 1, a push plate 205 is fixedly installed at the output end of the second cylinder 204, a third cylinder 206 is symmetrically fixedly installed at both ends of the upper surface of the base plate 1, a discharge plate 207 is fixedly installed at the output end of the third cylinder 206, and a discharge bin 208 is symmetrically fixedly installed on one side of the upper surface of the base plate 1.

[0036] In this embodiment, cylinder 204 extends and, after slide 202 moves to the pressing station, push plate 205 abuts against slide 202 to fix slide 202, improving stability during pressing. After pressing, cylinder 206 retracts, causing unloading plate 207 to move and pull the workpiece above placement plate 303 into unloading bin 208 for automatic unloading. This allows one workpiece to be pressed while another is heated, enabling alternating operations. After pressing, the workpiece is automatically removed, replacing manual unloading, accelerating the unloading speed of workpieces, and improving pressing efficiency.

[0037] like Figure 3-5 As shown, in this embodiment, a rotating plate 302 is rotatably connected to the upper outer side of the support rod 301. Multiple arc-shaped grooves 305 are formed at equal angles on one side surface of the rotating plate 302. One end of the slider 306 passes through the slide groove 304 and is slidably connected to the arc-shaped groove 305 at the corresponding position. A gear ring 307 is fixedly installed on the other side surface of the rotating plate 302. A motor 308 is fixedly installed inside the slide block 202. A first gear 309 that meshes with the gear ring 307 is fixedly installed at the output end of the motor 308.

[0038] In practice, the motor 308 operates, driving the first gear 309 to rotate, which in turn drives the gear ring 307 to rotate, causing the rotating plate 302 to rotate. At this time, the arc groove 305 rotates synchronously, pushing the slider 306 to move inside the slide groove 304. The workpiece placed above the placement plate 303 is clamped and fixed by multiple clamping components 4.

[0039] Example 2

[0040] Based on Embodiment 1, in order to compensate for the problem that the clamping component 4 easily hinders the workpiece from being moved out of the placement plate 303.

[0041] like Figure 3 , Figure 5 and Figure 6As shown, in this embodiment, the clamping assembly 4 includes: multiple connecting seats 401 fixedly installed on the upper surface of multiple sliders 306; a rotating block 402 rotatably connected to the inside of the connecting seat 401; a clamping plate 403 movably sleeved on one end of the rotating block 402; a second gear 404 fixedly installed at the other end of the rotating block 402 penetrating the connecting seat 401; an electric push rod 405 fixedly installed on one side surface of the connecting seat 401; a rack 406 fixedly installed at the output end of the electric push rod 405 and meshing with the second gear 404; and bolts detachably connecting the rotating block 402 and the clamping plate 403.

[0042] In specific implementation, the clamping plate 403 is detachably connected to the rotating block 402 and the clamping plate 403 by bolts, making it easy to disassemble and replace. When clamping workpieces of different shapes, the clamping plate 403 of the corresponding shape is replaced. After the worker places the workpiece and roughly adjusts its position, the clamping plate 403 can fit against the surface of the workpiece and automatically position it. This facilitates the automatic calibration of the workpiece position during clamping after it is placed on the placement plate 303, replacing manual placement and positioning, speeding up the loading and unloading of workpieces, and thus improving the pressing rate of the workpiece. After pressing, the electric push rod 405 retracts, driving the rack 406 to move, causing the rack 406 to rotate the second gear 404, which in turn causes the rotating block 402 to drive the clamping plate 403 to flip downwards, so that the clamping plate 403 does not block the workpiece, making it easier for the unloading plate 207 to push the workpiece off the surface of the placement plate 303.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
