Description

Technical Field

[0001] The invention relates to the technical field of nut aperture detection, and more specifically to a nut go / no-go gauge full inspection machine. Background Art

[0002] The nut go and no-go gauge full inspection machine is an automated equipment specially used to detect whether the nut size is qualified; the go and no-go gauge is a kind of measuring tool. The "go gauge" is used to check the minimum physical size of the nut, that is, whether the lower limit value of the nut hole diameter meets the requirements, and those that pass are qualified; the "no-go gauge" is used to check the maximum physical size of the nut, that is, whether the upper limit value of the nut hole diameter meets the requirements, and those that cannot pass are qualified. The nut go and no-go gauge full inspection machine simulates the process of manual use of go and no-go gauge inspection, but with higher efficiency and more stable accuracy; it plays a vital role in the nut production process; it can effectively screen out nut products with unqualified sizes, ensure the consistency and stability of product quality, thereby improving the quality of nuts in the entire production batch and meeting the needs of various application scenarios such as mechanical assembly.

[0003] Existing nut go / no-go gauge full inspection machines usually first transport the nuts to the inspection station in an orderly manner through a feeding device such as a vibrating plate. At the inspection station, the go / no-go gauge detection mechanism is used to conduct a comprehensive inspection of the nut aperture. After the inspection is completed, the sorting system pushes qualified nuts and unqualified nuts to different discharge channels respectively, thereby realizing automatic sorting. The method of first inspecting and then sorting requires sorting the nuts after the inspection is completed, so a special sorting system and control system are required, which increases the complexity of the equipment and the manufacturing cost. In view of this, we propose a nut go / no-go gauge full inspection machine. Summary of the invention

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention arranges a through gauge sorting component, a stop gauge sorting component and a defective product discharge port on a detection mechanism, and uses a through gauge screw to screw into the screw hole of the nut. If the through gauge screw cannot pass through the screw hole of the nut, it means that the inner diameter of the nut is lower than the lower limit standard, and it is determined to be a defective product. The nut is immediately transported into a No. 1 defective product box through the through gauge sorting component. If the through gauge screw can pass through the screw hole of the nut, it is determined that the inner diameter of the nut meets the lower limit standard, and the nut is transported to the stop gauge sorting component for detection through a rotating positioning component. When it is detected whether the nut meets the lower limit standard of the screw hole, the nut can be sorted, and then the stop gauge screw is used to screw into the screw hole of the nut that meets the lower limit standard. If the stop gauge screw cannot pass through the screw hole of the nut, the nut is transported to the stop gauge sorting component for detection. , it means that the screw hole of the nut does not exceed the upper limit standard of the screw hole, and it is a good product. The nut is transported into the No. 2 good product box through the stop gauge sorting component. If the stop gauge screw can pass through the screw hole of the nut, it means that the screw hole of the nut exceeds the upper limit standard and is judged to be a defective product. The nut is then transported to the defective product discharge port through the rotary positioning component and enters the No. 3 defective product box. The nut can be sorted when it is detected whether the nut meets the upper limit standard of the screw hole. The nut can be sorted while the detection is achieved, and there is no need to equip a special sorting system and control system, which reduces the complexity and manufacturing cost of the equipment and avoids the problem of occupying detection resources by testing the upper limit standard of defective nuts below the lower limit standard.

[0026] 2. The present invention also provides a semicircular groove 1 on the side wall of the first rotating plate and a semicircular groove 2 on the side wall of the second rotating plate. The semicircular groove 1 and the semicircular groove 2 are combined to form a circular groove hole. When the through-gauge screw can be screwed into the screw hole of the nut, the through-gauge screw will pass through the circular groove hole, ensuring that the through-gauge screw has sufficient room to move. When the through-gauge screw cannot be screwed into the screw hole of the nut, the through-gauge screw will press the nut downward, causing the nut to squeeze the first rotating plate and the second rotating plate, squeezing the first rotating plate and the second rotating plate apart, and the nut falls into the first guide plate below and enters the No. 1 defective product box. At this time, the first rotating plate and the second rotating plate are reset by the elastic force of the torsion spring, and the circular groove hole ensures the space for the through-gauge screw to rotate and rise, thereby preventing the first rotating plate and the second rotating plate from obstructing the through-gauge screw.

[0027] 3. The present invention also provides a trapezoidal groove 1 on the bottom surface of the first rotating plate and a trapezoidal groove 2 on the bottom surface of the second rotating plate. The trapezoidal groove 1 and the trapezoidal groove 2 are combined to form a nut-shaped groove. The nut-shaped groove can ensure that when the through-gauge screw or the stop-gauge screw is screwed into a part of the screw hole of the nut and cannot be screwed in further, the nut will be brought into the bottom surfaces of the first rotating plate and the second rotating plate. When the through-gauge screw or the stop-gauge screw rotates and rises, it can drive the nut to be screwed into the nut-shaped groove, so that the nut is restricted by the nut-shaped groove and cannot rotate. The through-gauge screw or the stop-gauge screw can smoothly rotate to disengage from the nut, causing the nut to fall, further solving the problem of difficulty in sorting and disengaging the nut when the through-gauge screw or the stop-gauge screw is screwed into a part of the screw hole of the nut and cannot be screwed in further.

[0028] 4. The present invention also designs an anti-stuck plate. The inclined surface on one side of the top surface of the anti-stuck plate can enable the nut to move smoothly from the top surface of the testing platform to the top surface of the anti-stuck plate. The arc surface set on the other side of the top surface of the anti-stuck plate can smoothly guide the nut into the top surfaces of the first rotating plate and the second rotating plate. The semi-arc plate on one side of the top surface of the second rotating plate can guide the nut from the top surface of the second rotating plate into the top surface of the testing platform, ensuring that the rotating positioning assembly can drive the nut to move on the testing platform smoothly, avoiding the problem of the nut being stuck due to the height difference between different structures, causing the equipment to fail.

[0029] 5. The present invention also provides a positioning groove that matches the shape of the nut on the lower end side wall of the Z-shaped plate, so that the nut transported to the detection mechanism by the vibration loading tray is positioned by the positioning groove of the Z-shaped plate, thereby ensuring that the nut cannot rotate in the positioning groove, which is beneficial for the nut to remain stable when the through gauge screw or the stop gauge screw is screwed in or out, thereby improving the stability of the operation. The limit plate arranged on the top of the positioning groove can further ensure that when the through gauge screw or the stop gauge screw is screwed out of the nut, the nut is unlikely to move up, and the nut always remains in the positioning groove.
