[0016] In order to make the patent purposes, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0017] In order to illustrate the technical solutions of the present application, the following specific embodiments are used to illustrate the technical solutions of the present application.

[0018] In order to facilitate the description, only parts related to the embodiments of the present application are shown.

[0019] In combination with Figures 1-3As shown, the roundness detection device includes a machine base 1, on which a detection platform 2 is provided. The detection platform 2 has a rotatable feeding tray 3, and the feeding tray 3 has four positioning ports 4. The machine base 1 is provided with a vibrating feeding tray 5, a roundness detection mechanism, a sorting frame 7, and a feeding rack 8 in sequence corresponding to the four positioning ports 4. The detection platform 2 has a sorting port and a feeding port 10 corresponding to the sorting frame 7 and the feeding rack 8, respectively. A movable baffle 9 is provided in the sorting port. The roundness detection mechanism includes a detection seat 11, with a sliding sleeve 12 and a top frame 13 respectively at the front and rear of the detection seat 11. A push rod 14 is inserted into the sliding sleeve 12, and a go gauge 15 is provided at the bottom of the push rod 14. A push cylinder 16 is provided on the top frame 13, and the drive shaft of the push cylinder 16 is connected to the top of the push rod 14. The detection platform 2 has a through-hole facing the go gauge, and the machine base 1 has a buffer mechanism corresponding to the through-hole.

[0020] In the field of precision manufacturing, roundness, as one of the important geometric features, directly affects product quality and performance. Powder metallurgy thin-walled ring parts are crucial components in industrial manufacturing, making their inspection essential. This roundness inspection device can be used to check the roundness of ring parts before they leave the factory.

[0021] When using this device to detect the roundness of ring parts, a certain number of ring parts are first placed into a vibrating feeder. The vibrating feeder then feeds the ring parts one by one to the detection table in an orderly manner. Once the current ring part is on the detection table and positioned within the positioning port, the feeder rotates one station, and the current ring part is delivered to the detection station. The roundness detection mechanism then detects and determines the roundness of the ring part. Simultaneously, the previous ring part is at the sorting port, and the next ring part is delivered to the positioning port at the loading position. If the roundness of the previous ring part does not meet the requirements, the sorting port opens, and the previous ring part falls onto the sorting rack. If the roundness of the previous ring part meets the requirements, the feeder rotates one more station, and the previous ring part falls from the unloading port onto the unloading rack. This allows for rapid detection of the roundness of ring parts.

[0022] In this device, such as Figures 1-2 The edge of the detection table 2 is formed with a retaining ring 6, and the retaining ring 17 has two slots 18 in the front and rear directions. The outlet of the feeding tray 5 is connected to the front slot. The detection seat 11 is provided with a pushing cylinder 19, and the drive shaft of the pushing cylinder 19 is provided with a push block 20 facing the rear slot 18. The buffer mechanism includes a fixed sleeve 20 installed on the machine base 1. A buffer rod 21 is inserted into the fixed sleeve 20. A buffer seat 22 is provided above the buffer rod 21, and a stop block is provided below the buffer rod 21. The buffer seat 22 is located in the through-hole. A spring 23 is provided on the buffer rod 21 between the fixed sleeve 20 and the buffer seat 22.

[0023] In the present embodiment, the edge of the detection table is formed with a stop ring, and the edge of the stop plate is also formed with a matching stop ring. When the ring is fed by the vibrating feeder, the last ring on the vibrating feeder pushes the current ring of the previous ring into the positioning opening at the feeding position, and then the feeder is rotated by one station, the current ring is sent to the detection station, and then the push block pushes the current ring by a small distance, and the current ring is completely located in the buffer seat, and then the push cylinder pushes the go gauge to move downward, and the go gauge is lowered by the same distance each time.

[0024] If the size of the ring inner hole is slightly larger than or equal to the size of the go gauge, the roundness of the ring meets the design requirements, and the go gauge can pass through the ring smoothly. If the size of the ring inner hole is smaller than the size of the go gauge, the roundness of the ring does not meet the design requirements. Then in the detection process, the go gauge is pressed down on the ring, the buffer seat is moved downward by a small distance, the spring is compressed, and the ring is lowered by a small distance, so as to avoid being damaged by the go gauge. After the detection is completed, the go gauge is reset, and the buffer seat is also reset under the action of the spring.

[0025] As shown in Figures 1-3 , the feeder 3 is provided with a pair of clamping blocks 24 corresponding to each positioning opening 4. The inner side of the clamping block 24 is provided with a clamping groove. When the ring is pushed into the positioning opening at the feeding position, the ring is located in the two clamping grooves, and the clamping block plays a role in limiting the ring, which can prevent the ring from jumping up and down during the entire detection process, thereby improving the stability of the entire detection process.

[0026] As a specific structure, as shown in Figure 2 , the machine table 1 is provided with a stand 26, the stand 26 is provided with a sorting cylinder 27, the sorting cylinder 27 is slidably provided with a sliding seat 28, the sliding seat 28 is provided with the stop plate 9, and the driving shaft of the sorting cylinder 27 is connected with the sliding seat 28.

[0027] After the detection of the current ring is completed, the feeder is rotated by one station, and the current ring is located on the stop plate. If the roundness of the current ring does not meet the requirements, at this time the sorting cylinder drives the sliding seat to retreat, the stop plate also retreats backward, the sorting opening is opened, and the current ring falls from the sorting opening to the sorting frame for unloading.

[0028] Finally, as shown in Figures 1-2 , the machine table 1 is provided with a fixing frame 29, and the fixing frame 29 is provided with an inductor 30 towards the outlet of the vibrating feeder, and the inductor is located directly above the feeding position. When the last ring on the vibrating feeder pushes the current ring of the previous ring into the positioning opening at the feeding position, the inductor senses and transmits a signal to the control end, and the control end controls and drives the feeder to rotate by one station.

[0029] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
