Description

Technical Field

[0001] This utility model relates to the field of steel ball sorting, and in particular to an automatic sorting device for soft and hard steel balls after heat treatment. Background Technology

[0002] During the heat treatment and circulation process, occasionally soft or defective steel balls may be mixed into the hardened balls after quenching. This is especially true for a very small number of individual steel balls that have abnormal product quality due to equipment malfunctions (indicators such as size and hardness not meeting the standards), as well as residual soft balls of the same specification mixed into the turnover drum. These must be detected in time and 100% selected and removed to ensure product quality.

[0003] A search of Chinese Patent Publication No. CN222019995U reveals a discharge device for heat-treated bearing steel balls. This patent includes a base, a large ball sorting mechanism, a sorting disc, a receiving box, and a waste box. The large ball sorting mechanism is located in the middle of the base for screening steel balls larger than the product diameter. In this embodiment, a sorting disc is located at the end of the base, and multiple guide rods are equidistantly arranged on the top surface of the sorting disc. The ends of the guide rods extend beyond the sorting disc, and the receiving box is located below the ends of the guide rods. A waste box is located below the end of the sorting disc. This device can effectively screen steel balls of different specifications within a standard product. However, current automatic sorting devices for heat-treated steel balls struggle to sort steel balls that do not meet the hardness requirements. During steel ball sorting, steel balls with diameter and hardness that do not meet the requirements are often sorted separately, increasing equipment costs and floor space, and making operation cumbersome, affecting sorting efficiency and consequently impacting subsequent steel ball processing, leading to a decrease in the product qualification rate of the steel balls.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-6As shown, an automatic sorting device for soft and hard steel balls after heat treatment includes a mounting frame 101. A fixing plate 102 is bolted to the inside of the mounting frame 101. A guide frame 103 is bolted to the top of the mounting frame 101. A guiding mechanism is provided on the mounting frame 101, including an inclined guide plate 201 with several grooves 202 on its top. The guide plate 201 is bolted to the mounting frame 101. Several evenly distributed partition plates 203 are bolted to the guide plate 201, with the distance between two adjacent partition plates 203 being the same as the diameter of the steel balls required for production. The grooves 202 are located between two adjacent partition plates 203. A blocking mechanism is installed on the mounting frame 101, including two opposing mounting columns 301 welded to the top sides of the mounting frame 101. A blocking plate 305 is movably disposed inside the mounting columns 301. Before sorting, the steel balls moving from the guide frame 103 to the guide plate 201 are blocked. The blocking plate 305 is located above the end of the guide frame 103. The guide plate 201 is equipped with a sorting mechanism located in the middle section of the guide plate 201. The sorting mechanism includes a first sorting structure, a second sorting structure, and a third sorting structure. The first sorting structure includes a rotating shaft 401, which is rotatably connected to the inside of the mounting frame 101. A flipping plate 402 is bolted to the rotating shaft 401. The flipping plate 402 cooperates with the guide plate 201 to sort steel balls with small diameters. The second sorting structure is used to sort steel balls with insufficient hardness. The third sorting structure is used to sort steel balls with large diameters. When the steel balls pass through the guide plate 201, the three sorting structures can quickly sort out steel balls that are not up to standard in size and hardness, greatly improving the sorting efficiency. The mounting frame 101 is equipped with several sets of collection mechanisms.

[0027] In this embodiment, the second sorting structure includes a hardness detection component 405 and a hydraulic rod 406. The hardness detection component 405 uses a commercially available steel ball hardness testing device, which is not limited here. The hardness detection component 405 and the hydraulic rod 406 are electrically connected. The hardness detection component 405 is fixedly installed on the side of the baffle plate 305 near the guide frame 103. The hydraulic rod 406 is bolted to the mounting frame 101. The output end of the hydraulic rod 406 is bolted to a lifting frame 407. The lifting frame 407 and the top of the tilting plate 402 are provided with the same groove as the guide plate 201. 202. When the tilting plate 402 and the lifting frame 407 are in a high position, the guide plate 201, the tilting plate 402 and the lifting frame 407 can form a complete and continuous guide channel. The lifting frame 407 cooperates with the guide plate 201 to sort steel balls that do not meet the hardness standard. When the hardness detection component 405 detects a steel ball that does not meet the hardness standard, the hydraulic rod 406 at the corresponding position of the hardness detection component 405 will drive the lifting frame 407 to descend, so that the steel ball falls when it moves to the position of the lifting frame 407 on the guide plate 201, thereby sorting the steel balls that do not meet the hardness standard.

[0028] In this embodiment, a slope 204 is provided at the top of the partition plate 203, and the third sorting structure includes a slope 408, which is welded to the top of the partition plate 203. Since the distance between the partition plates 203 is the same as the diameter of the standard steel ball, when the larger diameter steel ball rolls in the groove 202 on the guide plate 201, it will roll along the slope 408 to the top of the two adjacent guide plates 201, and then move to the slope 204. In this way, the sorting operation of the larger diameter steel ball is completed.

[0029] In this embodiment, a motor 302 is bolted to the top of a mounting post 301. The output end of the motor 302 is connected to a lead screw 303 via a coupling. The lead screw 303 is rotatably connected inside the mounting post 301. A connecting rod 304 is threaded onto the lead screw 303. The connecting rod 304 is bolted to a baffle plate 305. The motor 302 can drive the lead screw 303 to rotate. The lead screw 303 drives the connecting rod 304 and the baffle plate 305 to move up and down. When each batch of steel balls rolls from the guide frame 103 onto the guide plate 201, the baffle plate 305 descends until the distance between it and the guide plate 201 is the same as the diameter of the steel ball. At this time, the smaller diameter steel balls will pass under the baffle plate 305, thus separating the smaller diameter steel balls.

[0030] In this embodiment, a transmission rod 403 is bolted to the side of the flip plate 402. A transmission frame 404 is fitted onto the transmission rod 403. The transmission frame 404 is bolted to the connecting rod 304. The arrangement of the transmission rod 403 and the transmission frame 404 ensures that when the blocking plate 305 is in a low position, the flip plate 402 is also in a low position. At this time, a gap is formed between the guide plate 201 and the flip plate 402. After passing through the blocking plate 305, the smaller diameter steel balls will roll down along the guide plate 201 into the gap, completing the sorting operation of the smaller diameter steel balls.

[0031] In this embodiment, a guide rod 306 is bolted to the mounting column 301 away from the motor 302, and a lifting block 307 is slidably connected to the guide rod 306. The lifting block 307 is bolted to the baffle plate 305.

[0032] In this embodiment, the collection mechanism includes a first collection box 501, a second collection box 502, a third collection box 503, and a fourth collection box 504. The first collection box 501 is located at the bottom of the guide plate 201 and is bolted to one side of the mounting frame 101. A fixing frame 104 is bolted to one side of the mounting frame 101. The second collection box 502 is located on the top of the fixing frame 104 and is positioned below the end of the inclined plate 408. The third collection box 503 is located inside the mounting frame 101 and below the lifting frame 407. The fixing plate 102 is located between the third collection box 503 and the fourth collection box 504. The fourth collection box 504 is located inside the mounting frame 101 and below the flip plate 402.

[0033] Working principle: When in use, the steel balls to be sorted move in batches from the guide frame 103 onto the guide plate 201, so that each ball rolls in a horizontal line towards the blocking plate 305. Before each sorting, the output shaft of the control motor 302 drives the lead screw 303 to rotate. The lead screw 303 drives the connecting rod 304 and the blocking plate 305 to move up and down. When each batch of steel balls rolls from the guide frame 103 onto the guide plate 201, the blocking plate 305 descends to a distance from the guide plate 201. With the same diameter as the steel balls, smaller diameter steel balls will pass under the baffle plate 305. When the baffle plate 305 is in a low position, the flip plate 402 is also in a low position. At this time, a gap is formed between the guide plate 201 and the flip plate 402. After passing through the baffle plate 305, the smaller diameter steel balls will roll down along the guide plate 201 into the gap and finally fall into the fourth collection box 504, completing the sorting operation of the smaller diameter steel balls. After all the smaller steel balls have rolled into the fourth collection box 504, the process is started. The dynamic hardness testing component 405 performs hardness testing on the remaining steel balls. If a steel ball with insufficient hardness is encountered, the hydraulic rod 406 at the corresponding position of the hardness testing component 405 will drive the lifting frame 407 to descend, thereby creating a gap between the lifting frame 407 and the guide plate 201. Then, the motor 302 controls the blocking plate 305 to rise. At this time, all steel balls roll down along the grooves 202 on the guide plate 201. Steel balls that meet the size and hardness standards fall directly into a groove along the guide plate 201. Inside the first collection box 501, larger diameter steel balls roll along the groove 202 on the guide plate 201, then roll along the inclined plate 408 to the top of the two adjacent guide plates 201, thus moving onto the inclined surface 204 and finally entering the second collection box 502. This process completes the sorting of larger diameter steel balls. Steel balls that do not meet the hardness standard will fall from the gap between the lifting frame 407 and the guide plate 201 and enter the third collection box 503. This process is used to sort steel balls in batches.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
