Abstract
Description
Technical Field
[0001] This invention relates to the field of parts inspection technology, specifically to a device for performing full inspection of the inner hole and length through cyclic rotation. Background Technology
[0002] In the field of high-precision equipment, the dimensional requirements of the components are very high. Therefore, after the components are manufactured, they must be inspected to remove defective parts that do not meet the dimensional requirements. The inspection of the components includes the inspection of the inner hole and length. The inner hole is widely present in various bushing-type parts and plays an important role in the operation of the parts.
[0003] For example, patent document CN208282744U discloses a workpiece inner hole detection device and a detection production line having the detection device, including a workpiece inner hole detection device with a material distribution function, a feeding mechanism, and a discharging mechanism for transferring qualified workpieces to the next station. The feeding mechanism is a robot arm that grasps a fan blade bushing and moves it toward the workpiece inner hole detection device with a constant force. The workpiece inner hole detection device includes a detection mechanism, including a detection rod fixedly connected to the rotating shaft via a support plate. The feeding mechanism drives the fan blade bushing to be detected to move toward the detection rod with a constant force and engages with the detection rod. The detection rod has a guide portion for inserting the fan blade bushing and a measuring section for detecting whether the fan blade bushing is qualified. The measuring section corresponds to the inner hole size of the qualified workpiece.
[0004] Since the feeding mechanism of the above device is a robotic arm, the workpieces need to be fed to the inner hole inspection device one by one during the feeding inspection. When a large number of workpieces need to be inspected, the efficiency is extremely low. Therefore, there is an urgent need for a device that can perform full inspection of the inner hole and length by cyclic rotation. Summary of the Invention
[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a device for cyclically rotating and inspecting the inner hole and length, which has the function of cyclically screening and inspecting parts.
[0006] To solve the above problems, the present invention adopts the following technical solution:
[0007] A device for cyclically inspecting the inner diameter and length of a rotating part includes a frame, a vibratory feeder assembly, a motor, a pulley, a belt, a controller, a side plate, a good product discharge pipe, and an inspection mechanism assembly. The vibratory feeder assembly is mounted on the top of the frame, and the controller is mounted on the frame. The motor is mounted on the frame via a fixed plate, and a pulley is mounted on the output end of the motor. A belt is movably fitted onto the pulley. A side plate is fixed on the side of the frame away from the vibratory feeder assembly, and the inspection mechanism assembly is mounted on the side plate. A good product discharge pipe is located below the inspection mechanism assembly and is connected to the side plate.
[0008] The aforementioned inspection mechanism assembly uses a vibratory feeder to continuously feed parts from the feeding track, and then a motor drives a star-shaped turntable to rotate back and forth, allowing the parts to cooperate with the inner hole stopper on the star-shaped turntable for screening. Because the star-shaped turntable and the inner hole stopper are constantly working back and forth, the purpose of continuous automatic inspection of parts can be achieved.
[0009] As an optimization, the vibratory feeder assembly includes a vibratory machine, a vibratory feeder, and a feeding track. The vibratory feeder is mounted on the top of the vibratory machine, and the feeding track is connected to the vibratory feeder.
[0010] As an optimization, the feeding track is equipped with an adjustable lower limit baffle and an adjustable upper limit baffle, which can screen the material parts on the vibratory feeder.
[0011] As an optimization, the side plate includes a connecting groove, a through hole, and a rotating shaft. The connecting groove is provided on the side plate and is connected to the feeding track. The through hole is provided on the side plate and a rotating shaft is installed on the through hole. One end of the rotating shaft is connected to the end of the belt away from the motor via a pulley.
[0012] As an optimization, the inspection mechanism assembly includes a star-shaped turntable, a cam plate, bolts, and a cover. The cam plate is mounted on the star-shaped turntable and is connected to the star-shaped turntable by bolts. A cover is mounted on the other side of the cam plate away from the star-shaped turntable.
[0013] As an optimization, the star-shaped turntable includes mounting holes, inclined plates, an upper base, sliding grooves, defective product unloading ramps, good product unloading ramps, threaded holes, a lower base, and an inner hole stopper. The star-shaped turntable has mounting holes that are movably fitted with the rotating shaft. Inclined plates are arranged in a ring inside the star-shaped turntable. An upper base is mounted on one side of the star-shaped turntable. Defective product unloading ramps and good product unloading ramps are arranged on the star-shaped turntable. Threaded holes are arranged on the other side of the star-shaped turntable and are threadedly connected to bolts. A lower base is located on the side of the star-shaped turntable away from the upper base. Both the upper and lower bases have sliding grooves arranged in a ring, and an inner hole stopper slides in fit on the sliding grooves.
[0014] The aforementioned sliding groove allows the inner hole plug rod to move within the sliding groove.
[0015] The aforementioned defective product unloading ramp and good product unloading ramp are designed to collect and unload parts from the inner hole plug rod.
[0016] The aforementioned inner hole stopper rod can cooperate with the star-shaped turntable to screen parts with inner holes during rotation.
[0017] As an optimization, the cam disk includes a cam and a limiting groove. The cam disk is provided with a cam, and the limiting groove is arrayed on the cam disk. The limiting groove cooperates with the threaded hole.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0019] This invention discloses a device for performing full inspection of the inner hole and length cyclic rotation. Through the setting of the vibratory feeder assembly, it can feed a large number of workpieces with high efficiency. The parts enter the feeding track of the vibratory feeder assembly one by one. When the parts pass the adjustable lower limit baffle, the parts with short length will flow out through the notch of the adjustable lower limit baffle and be rejected as defective products. The parts that are not rejected through the notch of the lower limit baffle continue to flow down and pass through the adjustable upper limit baffle. The parts with long length cannot pass through the notch of the upper limit baffle and instead enter the defective product hopper along the upper limit baffle and are rejected. The parts with the correct length enter the inspection mechanism assembly through the notch of the upper limit baffle.
[0020] In summary, this invention, through the configuration of the inspection mechanism assembly, uses a vibratory feeder to continuously feed parts from the feeding track, and then a motor drives a star-shaped turntable to rotate reciprocally, allowing the parts to cooperate with the inner hole stopper on the star-shaped turntable for screening. Because the star-shaped turntable and the inner hole stopper are constantly working back and forth, the purpose of continuous automatic inspection of parts can be achieved, resulting in high efficiency.

[0045] Please see Figure 1-17 This is Embodiment 2 of the present invention.
[0046] Further implementing the first embodiment, in this embodiment, the inspection mechanism assembly 9 includes a star-shaped turntable 11, a cam disk 12, bolts 13, and a cover 14. The cam disk 12 is mounted on the star-shaped turntable 11, and the cam disk 12 is connected to the star-shaped turntable 11 by bolts 13. A cover 14 is mounted on the other side of the cam disk 12 away from the star-shaped turntable 11.
[0047] In this embodiment, the star-shaped turntable 11 includes mounting holes 111, inclined plates 112, an upper base 113, a sliding groove 114, a defective product unloading ramp 115, a good product unloading ramp 116, threaded holes 117, a lower base 118, and an inner hole stopper 119. The star-shaped turntable 11 has mounting holes 111 that are movably fitted with the rotating shaft 73. Inclined plates 112 are arranged in a ring inside the star-shaped turntable 11. The upper base 113 is mounted on one side of the star-shaped turntable 11. The star-shaped turntable 11 has defective product unloading ramps 115 and good product unloading ramps 116. Threaded holes 117 are arranged on the other side of the star-shaped turntable 11. 117 is threadedly connected to bolt 13. A lower base plate 118 is provided on the side of the star-shaped turntable 11 away from the upper base plate 113. Both the upper base plate 113 and the lower base plate 118 are arranged in a ring with sliding grooves 114. An inner hole stopper rod 119 is slidably fitted on the sliding groove 114. The setting of the sliding groove 114 allows the inner hole stopper rod 119 to move within the sliding groove 114. The setting of the defective product unloading ramp 115 and the good product unloading ramp 116 allows the parts on the inner hole stopper rod 119 to be unloaded and collected. The setting of the inner hole stopper rod 119 can cooperate with the star-shaped turntable 11 to screen the parts with inner holes when rotating.
[0048] The vibrating plate 22 drives the parts to be continuously fed from the feeding track 23. Then, the motor 3 drives the star-shaped turntable 11 to rotate back and forth, so that the parts can cooperate with the inner hole stopper 119 on the star-shaped turntable to screen the parts. Since the star-shaped turntable 11 and the inner hole stopper 119 are constantly working back and forth, the purpose of continuous automatic inspection of parts can be achieved.
[0049] In this embodiment, the cam disk 12 includes a cam 121 and a limiting groove 122. The cam disk 12 is provided with a cam 121 and the limiting groove 122 is arrayed on the cam disk 12. The limiting groove 122 cooperates with the threaded hole 117.
[0050] Based on the above embodiments, its working principle is as follows:
[0051] Parts are fed by vibration of vibrating plate 22 and enter the feeding track 23 one by one. When the parts pass through the adjustable lower limit baffle 31, the parts that are short will flow out through the notch of the adjustable lower limit baffle 31 and be rejected as defective products. The parts that are not rejected through the notch of the adjustable lower limit baffle 31 continue to flow down and pass through the adjustable upper limit baffle 33. The parts that are long cannot pass through the notch of the adjustable upper limit baffle 33 and instead enter the defective product hopper along the adjustable upper limit baffle 33 and are rejected. The parts that are of the right length enter the inspection mechanism assembly 9 through the notch of the adjustable upper limit baffle 33.
[0052] The drive motor 3 drives the star-shaped turntable 11 to rotate via pulley 4 and belt 5. When the star-shaped turntable 11 rotates to the point where a part with an inner hole is aligned with any one of the multiple sets of inner hole stoppers 119 provided on the star-shaped turntable 11, if the inner hole of the part is not smaller than the inner hole stopper (lower limit), the inner hole stopper's inlet end is inserted into the part and completely passes through the part's inner hole. The inner hole stopper 119, along with the part, rotates with the star-shaped turntable 11 to the qualified discharge port, where it is discharged by the discharge ramp 116 and falls into the qualified product frame. In the middle; if the inner hole of the part is smaller than the inner hole stopper (lower limit), the inner hole stopper is only introduced into the inner hole of the part by the inlet end, but cannot pass through the inner hole stopper control end. The inner hole stopper inlet end carries the part along with the star-shaped turntable 11 to the unqualified discharge port, and is discharged by the defective product discharge ramp 115 and falls into the unqualified product frame. The vibrating plate 22 continuously feeds the part, and at the same time the star-shaped turntable 11 reciprocates. The inner hole stopper 119 on the star-shaped turntable 11 also reciprocates continuously, thereby achieving the purpose of continuous automatic inspection of parts.
