A powder metallurgy device capable of inspecting and sealing oil-impregnated bearings on a boat.

Abstract

This invention relates to the field of metallurgical process technology, specifically to a powder metallurgy device capable of detecting and sealing oil-impregnated bearings. It mainly includes a machine body, a detection mechanism (located inside the machine body), a placement mechanism (located on the left side of a fixed frame), and a sealing mechanism (located on one side of the placement box). When the sensor detects the oil-impregnated bearing blank, the motor drives the rotating shaft and the fixed sleeve to rotate one revolution. When the clamping plate rotates to the oil-impregnated bearing, the support block no longer contacts the arc-shaped plate. The tension spring drives the two moving blocks closer, causing the clamping plate to clamp and fix the oil-impregnated bearing. When the clamping plate rotates the oil-impregnated bearing 180 degrees, the two support blocks contact one end of the arc-shaped plate and move away from each other, causing the oil-impregnated bearing to fall into the placement box. Simultaneously, the rotating shaft, through the rotating plate, pushes the adjusting plate, the base, and the placement box to rotate a certain angle, allowing the oil-impregnated bearing to fall into the placement box in an orderly manner. This greatly reduces the workload of workers and improves the efficiency of the entire production line.

Description

Technical Field

[0001] This invention relates to the field of metallurgical process technology, specifically to a powder metallurgy device capable of detecting and sealing oil-impregnated bearings. Background Technology

[0002] Powder metallurgy involves using metal powders as raw materials and sintering the formed preforms at high temperatures. This process causes diffusion, welding, and recrystallization between powder particles, resulting in a dense metallurgical product. The sintering temperature and time parameters need to be adjusted according to the type and performance requirements of the material.

[0003] However, in the current market, the powder metallurgy production process of oil-impregnated bearings requires manual quality inspection of the formed oil-impregnated bearing blanks. After the quality inspection is completed, these formed oil-impregnated bearing blanks still need to be manually placed one by one into the boat. This manual operation mode greatly increases the workload of workers and also reduces the efficiency of the entire production line.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention involves placing the placement box in a placement slot on the base. When the sensor detects the oil-impregnated bearing blank, the motor starts, causing the rotating shaft and fixing sleeve to rotate one revolution. The fixing sleeve drives the fixing strip to rotate via the fixing block, and the fixing strip drives the clamping rod and clamping plate to rotate. When the clamping plate rotates to the oil-impregnated bearing, the support block no longer contacts the arc-shaped plate. The tension spring drives the two moving blocks to move closer, and the two moving blocks drive the two clamping rods and two clamping plates to move closer. The two clamping plates clamp and fix the oil-impregnated bearing. When the clamping plates continue to rotate, causing the oil-impregnated bearing to rotate 180 degrees, the two support blocks and the arc-shaped plate... When two parts of the bearing are in contact with each other and move away from each other, the two moving blocks move away from each other, which in turn moves the two clamping rods and the two clamping plates away from each other. As a result, the oil-impregnated bearing falls into the placement box. At the same time, when the shaft rotates one revolution, the shaft drives the rotating plate to rotate. The rotating plate pushes the adjusting plate and the base to rotate at a certain angle, which in turn drives the placement box to rotate at a certain angle. This allows the oil-impregnated bearings to fall into the placement box in an orderly manner without overlapping. As a result, these formed oil-impregnated bearing blanks do not need to be manually placed into the placement box one by one, which greatly reduces the workload of workers and improves the efficiency of the entire production line. When the electromagnet is energized, it attracts the cover plate. Simultaneously, the wedge magnet moves due to the repulsion between the electromagnet and the wedge magnet. As the wedge magnet moves, it pushes the second arc plate upward and squeezes the second elastic element. The second arc plate moves the mounting strip and the coating roller upward. The rotating cylinder is activated, causing the connecting shaft and the sleeve to rotate 90 degrees. The sleeve drives the connecting strip and the coating roller to rotate. At the same time, the connecting strip drives the electromagnet and the cover plate to rotate above the placement box. When the electromagnet is de-energized, the cover plate falls to seal the placement box. Simultaneously, the second elastic element pushes the second arc plate downward. The second arc plate pushes the wedge magnet to move. The second arc plate moves the mounting strip and the coating roller downward to contact the feeding sponge and apply the coating liquid. The rotating cylinder returns to its original position, causing the coating roller to return to its original position. When the coating roller returns to its original position, the liquid is applied to the gap between the cover plate and the placement box, sealing the gap between the cover plate and the placement box. This prevents oxidation during the firing process of the oil-impregnated bearing and improves the quality of the oil-impregnated bearing firing. By feeding an oil-impregnated bearing blank into the inlet, the blank falls to the left end of the rotating slide plate. When the oil content of the bearing meets the standard, its weight presses down on the rotating slide plate and squeezes the elastic element to a certain shrinkage length, causing the left end of the rotating slide plate to move down below the right end. The left end then slides onto the moving slide plate for the next step of production. When the oil content of the bearing blank is insufficient, it cannot press the left end of the rotating slide plate down below the right end, causing the defective bearing blank to slide from the right end of the rotating slide plate into the fixed frame. It is then removed and reprocessed. This process eliminates the need for manual inspection and sorting, resulting in high efficiency. Attached Figure Description

Detailed Implementation

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] like Figure 1-9 As shown, this application provides a powder metallurgy device capable of detecting and sealing oil-impregnated bearings, comprising: a machine body 1, a door panel 101 movably installed on the left side of the machine body 1, and a feed inlet 102 through-opening on the top surface of the machine body 1; An inspection mechanism 2 is provided inside the machine body 1. The inspection mechanism 2 includes a fixed frame 201 fixedly installed on the inner wall of the machine body 1. A fixed column 202 is fixedly installed on the top surface of the fixed frame 201. A rotating slide plate 203 is hinged to the upper end of the fixed column 202. The inspection mechanism 2 is used to inspect and divert oil-impregnated bearings. Specifically, such as Figure 1 As shown, the bottom left end of the rotating slide plate 203 is elastically connected to the top surface of the fixed frame 201 via an elastic element 204. A door panel 205 is rotatably installed on the right side of the body 1. A movable slide plate 206 is fixedly installed on the top left side of the fixed frame 201. The bottom surface of the movable slide plate 206 is fixedly connected to the left side of the fixed frame 201 via a support frame 207.

[0022] In this embodiment: the elastic element 204 applies elastic force to the rotating slide plate 203. When the oil-impregnated bearing blank falls to the left end of the rotating slide plate 203, the weight of the oil-impregnated bearing blank squeezes the elastic element 204, causing the rotating slide plate 203 to rotate. When the oil-impregnated bearing blank has the required oil content, the left end of the rotating slide plate 203 presses the elastic element 204 a certain distance, so that the left end of the rotating slide plate 203 is lower than the right end, and the oil-impregnated bearing blank slides onto the moving slide plate 206 for conveying. When the oil-impregnated bearing blank does not have the required oil content, the right end of the rotating slide plate 203 is lower than the left end, and the oil-impregnated bearing slides into the fixed frame 201 for subsequent processing.

[0023] A placement mechanism 3 is provided on the left side of the fixed frame 201. The placement mechanism 3 includes a placement box 319 located inside the body 1. A fixed sleeve 303 is provided above the placement box 319. A clamping rod 311 is provided on one side of the fixed sleeve 303. A clamping plate 312 is fixedly installed at one end of the clamping rod 311 by bolts. The placement mechanism 3 is used to place the oil-impregnated bearing. Specifically, such as Figure 1-6 As shown, a motor 301 is fixedly installed on the inner wall of the rear side of the machine body 1. A rotating shaft 302 is fixedly installed on the output end of the motor 301. The outer wall of the other end of the rotating shaft 302 is fixedly connected to the inner wall of the fixing sleeve 303. A fixing block 304 is fixedly installed on the outer wall of the fixing sleeve 303. A fixing strip 305 is fixedly installed on the other end of the fixing block 304.

[0024] In this embodiment: by turning on the motor 301, the rotating shaft 302 is driven to rotate, the rotating shaft 302 drives the fixing sleeve 303 to rotate, and the fixing sleeve 303 drives the fixing block 304 and the fixing strip 305 to rotate.

[0025] Specifically, such as Figure 1-6 As shown, a groove 306 is provided inside the fixing strip 305. Two movable blocks 307 are slidably installed on the inner wall of the groove 306. Tension springs 308 are fixedly installed near the side of the two movable blocks 307. Support blocks 309 are fixedly installed on the side of the two movable blocks 307 respectively. Two through grooves 310 are provided through the inner wall of the groove 306. The side of the two support blocks 309 is slidably connected to the inner wall of the two through grooves 310 respectively.

[0026] In this embodiment: the groove 306 allows the movable block 307 to move, and the tension spring 308 applies tension to the two movable blocks 307 so that the two movable blocks 307 always have a tension that brings them closer to each other.

[0027] Specifically, such as Figure 1-6 As shown, there are two clamping rods 311 and two clamping plates 312. The other ends of the two clamping rods 311 slide through the two sides of the fixing strip 305 and are fixedly connected to the two moving blocks 307 away from the side. A support plate 313 is fixedly installed on the left side of the moving slide plate 206. An arc plate 314 is fixedly installed on the other side of the support plate 313. The left end of the arc plate 314 is set in the shape of an arrow. Two support blocks 309 are slidably connected to the outer wall of the arc plate 314 near the side.

[0028] In this embodiment: when the two support blocks 309 slide in contact with the arc plate 314, the two support blocks 309 move away from each other, causing the two moving blocks 307 to move away from each other, and causing the two clamping rods 311 and the two clamping plates 312 to move away from each other. The left end of the arc plate 314 is set in an arrow shape to facilitate the two support blocks 309 to be spread apart.

[0029] Specifically, such as Figure 1-6 As shown, a sensor 315 is fixedly installed on the top surface of the left end of the mobile slide plate 206, a rotating plate 316 is fixedly installed on the outer wall of the rotating shaft 302, a base 317 is rotatably installed on the inner wall of the lower end of the body 1 through a damping bearing, a plurality of adjusting plates 318 are fixedly installed on the outer wall of the base 317, the side of the rotating plate 316 is slidably connected to the side of the adjusting plate 318, a placement groove is opened on the top surface of the base 317, and the inner wall of the placement groove is movably connected to the outer wall of the lower end of the placement box 319.

[0030] In this embodiment: when the oil-impregnated bearing blank is detected by the sensor 315, the motor 301 is started and the rotating plate 316 is rotated through the rotating shaft 302. The rotating plate 316 rotates one revolution, pushing the adjusting plate 318 and the base 317 to rotate at a certain angle, which in turn drives the placement box 319 to rotate at a certain angle, so that the oil-impregnated bearing blank can fall into the placement box 319 in an orderly manner without overlapping and piling up.

[0031] A sealing mechanism 4 is provided on one side of the placement box 319. The sealing mechanism 4 includes a connecting strip 409 located on one side of the placement box 319. An electromagnet 410 is fixedly installed on the bottom surface of one end of the connecting strip 409. An applicator roller 414 is provided on one side of the electromagnet 410. The sealing mechanism 4 is used to seal the placement box 319.

[0032] Specifically, such as Figure 1-9As shown, an L-shaped rod 401 is fixedly installed on the front side of the machine body 1, a placement plate 402 is fixedly installed on the upper end of the L-shaped rod 401, a cover plate 403 is provided on the top surface of the placement plate 402, a through groove 404 is provided on the front side of the machine body 1, a rotating cylinder 405 is fixedly installed on the inner wall of the lower end of the machine body 1, and a connecting shaft 406 is fixedly installed on the output end of the rotating cylinder 405.

[0033] In this embodiment: the placement plate 402 is used to support and place the cover plate 403, and the rotating cylinder 405 can drive the connecting shaft 406 to reciprocate 90 degrees.

[0034] Specifically, such as Figure 1-9 As shown, a limit plate 407 and a circular sleeve 408 are fixedly installed on the outer wall of the connecting shaft 406. Two limiters 423 are fixedly installed on the inner wall of the lower end of the machine body 1. The two limiters 423 are set vertically. The side of the limit plate 407 abuts against one end of the limiter 423. The outer wall of the circular sleeve 408 is fixedly connected to one end of the connecting strip 409.

[0035] In this embodiment, the connecting shaft 406 is limited by the setting of the limiting plate 407 and two limiters 423, with the two limiters 423 being set vertically, so that the connecting shaft 406 is less likely to rotate off-center or over-rotate, thereby improving the accuracy of the rotation of the connecting shaft 406.

[0036] Specifically, such as Figure 1-9 As shown, the circular sleeve 408 has an arc-shaped groove 411 inside. An arc-shaped plate 412 is slidably installed on the inner wall of the arc-shaped groove 411. An installation strip 413 is fixedly installed on the outer wall of the arc-shaped plate 412. An applicator roller 414 is fixedly installed on the bottom surface of the installation strip 413. A through hole 418 is opened through the inner wall of the arc-shaped groove 411. The side of the installation strip 413 is slidably connected to the inner wall of the through hole 418. The top surface of the arc-shaped plate 412 is elastically connected to the upper inner wall of the arc-shaped groove 411 through an elastic element 415. An installation rod 422 is fixedly installed on the left side of the fixed frame 201. A fixed plate 420 is fixedly installed on one end of the installation rod 422. A feeding sponge 421 is fixedly installed on the top surface of the fixed plate 420. The outer wall of the applicator roller 414 is slidably connected to the top surface of the placement box 319 and the top surface of the feeding sponge 421.

[0037] In this embodiment: the arc-shaped groove 411 allows the arc-shaped plate 412 to move. When the arc-shaped plate 412 moves, it drives the mounting strip 413 and the applicator roller 414 to move. The elastic element 415 applies a continuous elastic force to the arc-shaped plate 412. The feeding sponge 421 absorbs the applicator liquid. When the applicator roller 414 releases the pressure from the feeding sponge 421, the surface of the applicator roller 414 is coated with applicator liquid, which facilitates subsequent applicator application.

[0038] Specifically, such as Figure 1-9 As shown, a moving groove 416 is provided on the right side of the connecting strip 409 and the outer wall of the circular sleeve 408 and extends into the arc groove 411. A wedge magnet 417 is slidably connected to the inner wall of the moving groove 416. The wedge magnet 417 is magnetically connected to the electromagnet 410. An adjustment groove 419 is provided on the bottom surface of the arc plate 412. The inner wall of the adjustment groove 419 is slidably connected to the top surface of the wedge magnet 417.

[0039] In this embodiment: when the electromagnet 410 is energized, the electromagnet 410 and the wedge magnet 417 repel each other magnetically. The wedge magnet 417 moves and moves the arc plate 412 upward through the adjustment groove 419, thereby driving the mounting strip 413 and the application roller 414 upward. When the electromagnet 410 is not energized, the elastic force of the elastic element 415 drives the arc plate 412, the mounting strip 413 and the application roller 414 downward to contact the top surface of the placement box 319 for application.

[0040] The specific procedure is as follows: An oil-impregnated bearing blank is fed into the feed inlet 102 and falls to the left end of the rotating slide plate 203. When the oil content of the bearing meets the standard, its weight presses against the rotating slide plate 203 and compresses the elastic element 204 to a certain shrinkage length. This causes the left end of the rotating slide plate 203 to move lower than its right end, allowing it to slide onto the moving slide plate 206 for the next step of production. When the oil content of the bearing blank is insufficient, it cannot press the left end of the rotating slide plate 203 lower than its right end. The defective bearing blank then slides from the right end of the rotating slide plate 203 into the fixed frame 201, where it is then removed for reprocessing. No manual inspection is required. The classification process is highly efficient. When the sensor 315 detects the oil-impregnated bearing blank, the motor 301 starts, driving the rotating shaft 302 and the fixing sleeve 303 to rotate one revolution. The fixing sleeve 303 drives the fixing strip 305 to rotate through the fixing block 304. The fixing strip 305 drives the clamping rod 311 and the clamping plate 312 to rotate. When the clamping plate 312 rotates to the oil-impregnated bearing, the support block 309 no longer contacts the arc plate 314. The tension spring 308 drives the two moving blocks 307 to move closer. The two moving blocks 307 drive the two clamping rods 311 and the two clamping plates 312 to move closer. The two clamping plates 312 clamp and fix the oil-impregnated bearing. When the clamping plate 312 continues to rotate, driving the oil-impregnated bearing to rotate 180 degrees, the two support blocks 309 and the arc plate 314... The ends of the bearings move away from each other, causing the two moving blocks 307 to move away from each other, and causing the two clamping rods 311 and the two clamping plates 312 to move away from each other. This allows the oil-impregnated bearings to fall into the placement box 319. Simultaneously, when the rotating shaft 302 rotates one revolution, it drives the rotating plate 316 to rotate. The rotating plate 316 pushes the adjusting plate 318 and the base 317 to rotate at a certain angle, thereby causing the placement box 319 to rotate at a certain angle. This allows the oil-impregnated bearings to fall into the placement box 319 in an orderly manner without overlapping. Therefore, these formed oil-impregnated bearing blanks do not need to be manually placed into the placement box 319 one by one, greatly reducing the workload of workers and improving the efficiency of the entire production line. When the electromagnet 410 is energized, the electromagnet 41... The cover plate 403 is attracted by the magnet 417, which moves in opposition to the electromagnet 410. As the magnet 417 moves, it pushes the arc-shaped plate 412 upwards and presses against the elastic element 415. The arc-shaped plate 412 then moves the mounting strip 413 and the application roller 414 upwards. The rotating cylinder 405 is activated, causing the connecting shaft 406 and the sleeve 408 to rotate 90 degrees. The sleeve 408 then rotates the connecting strip 409 and the application roller 414. Simultaneously, the mounting strip 413 rotates the electromagnet 410 and the cover plate 403 above the placement box 319. The electromagnet 410 is de-energized, and the cover plate 403 falls to seal the placement box 319. At the same time, the elastic element 415 pushes the arc-shaped plate 412 downwards, which in turn moves the magnet 417.The arc-shaped plate 412 moves the mounting strip 413 and the coating roller 414 downwards to contact the feeding sponge 421 and apply the adhesive coating liquid. The rotating cylinder 405 returns to its original position, causing the coating roller 414 to return to its original position as well. When the coating roller 414 returns to its original position, it applies liquid to the gap between the cover plate 403 and the placement box 319, sealing the gap and preventing oxidation during the firing process of the oil-impregnated bearing, thus improving the quality of the oil-impregnated bearing firing.
