Description

Technical Field

[0001] The invention relates to the technical field of nuts, and in particular to a mechanical nut feeding mechanism suitable for preventing errors in nut width. Background Art

[0002] Traditional nut feeding guides cannot distinguish the correctness of nut widths and thus prevent nut width errors. When there are multiple nuts with similar appearances but different widths on the production line, nuts with the wrong widths are easily mixed into the nut feeding guides, causing finished products to be scrapped. On the basis of the nut feeding guides, a mechanical nut feeding structure with nut width error prevention is added to detect whether the width of each nut is correct. This can effectively solve the problem of nuts with the wrong widths being easily mixed into the nut feeding guides, reduce the defective rate within the project, and improve product quality. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a mechanical nut feeding mechanism suitable for preventing nut width errors.

[0004] The objective of the present invention is achieved through the following technical solutions:

[0005] A mechanical nut feeding mechanism suitable for nut width error prevention, comprising a mechanical nut feeding guide rail, a nut error prevention base, an error prevention guide plate, an error prevention detection rod, a connecting rod, and an error prevention baffle;

[0006] The nut error-proofing base is fixed to the nut feeding guide rail by bolts;

[0007] The error-proofing guide plate is fixed on the nut error-proofing base by bolts;

[0008] The error-proofing detection rod is installed in the circular groove of the nut error-proofing base;

[0009] The connecting rod is fixed on the error-proofing detection rod by bolts and springs;

[0010] The error-proofing baffle is fixed to the nut error-proofing base by bolts;

[0011] The nut error-proofing base realizes the functional area of ​​nut width error-proofing, including the feeding area, error-proofing area, and discharging area. The feeding area is used to place the nuts in, the error-proofing area is used to identify the width of the nuts, and the discharging area is installed on the nut feeding guide rail.

[0012] The error-proofing guide plate is located in the feeding area of ​​the nut error-proofing base. The error-proofing guide plate is designed to have an inclined surface on one side and an arc surface on the other side according to the structural characteristics of the hexagonal nut, with the help of the pressure when the nut is pressed by hand and the nut's own gravity. The width of the error-proofing guide plate h ≈ &> the hexagonal opposite side width s1 of the correct nut; if the correct nut is placed, the nut opposite side width s1 < the width h of the error-proofing guide plate, and the nut can fall horizontally in the form of the opposite side width s1 to enter the error-proofing area of ​​the nut error-proofing base; if the wrong nut is placed, the nut opposite side width s2 > the width h of the error-proofing guide plate, and the nut cannot enter the error-proofing area of ​​the nut error-proofing base, thereby realizing the function of preventing nuts with a large width from entering the error-proofing area of ​​the nut error-proofing base.

[0013] The error-proofing detection rod is located in the error-proofing area of ​​the nut error-proofing base, and the inner diameter r of the circular groove of the error-proofing detection rod is ≈ &<the hexagonal diagonal width e1 of the correct nut, r is the full-circle chamfer of the circular groove; if the correct nut is placed, the diagonal width e1 of the correct nut is greater than the inner diameter r of the circular groove of the error-proofing detection rod, r, the full-circle chamfer of the circular groove cooperates with the chamfer of the nut, and the correct nut can be positioned in the error-proofing area of ​​the nut error-proofing base. The connecting rod applies pressure to the nut through bolts and springs to press the nut against the error-proofing baffle, and the newly fed nut above can easily push the correct nut down to the discharging area of ​​the nut error-proofing base and fall into the nut feeding guide rail; if the wrong nut is placed, the diagonal width e2 of the wrong nut is less than the inner diameter r of the circular groove of the error-proofing detection rod, and the connecting rod automatically extends the error-proofing detection rod due to elastic force through bolts and springs, and the wrong nut is stuck in the circular groove, so that the nut can no longer be pressed from above to enter the feeding area of ​​the nut error-proofing base, thereby realizing the function of preventing nuts with small width from entering the discharging area of ​​the nut error-proofing base.

[0014] According to the width h of the anti-error guide plate ≈ & > the opposite width s1 of the correct nut and the inner diameter r of the circular groove of the anti-error detection rod ≈ & < the diagonal width e1 of the correct nut, the width h of the anti-error guide plate and the inner diameter r of the circular groove of the anti-error detection rod are designed to prevent nuts of incorrect width from entering the nut feeding guide rail.

[0015] The connecting rod connects the nut error proofing base and the error proofing detection rod together through bolts and springs, so that the error proofing detection rod can freely extend out of the nut error proofing base due to elastic force and can reciprocate.

[0016] The error-proofing baffle is located in the error-proofing area of ​​the nut error-proofing base, and the error-proofing detection rod applies pressure to the nut to press the nut against the error-proofing baffle.

[0017] Compared with the prior art, the present invention has the following positive effects:

[0018] On the basis of the nut feeding guide, a mechanical nut feeding structure with nut width error prevention is added to detect whether the width of each nut is correct. This can effectively solve the problem that nuts of incorrect width are easily mixed into the nut feeding guide, reduce the defective rate within the project, and improve product quality.

[0019] This application designs an error-proofing guide plate and an error-proofing detection rod based on the structural dimensions of the hexagonal nut and the size differences of the hexagonal width and diagonal width of different nuts. Whether the nut can pass through the error-proofing guide plate and the error-proofing detection rod is used to determine whether the nut of the correct width is placed. When the nut of the wrong width is placed, the error-proofing guide plate blocks the wrong nut from entering or the error-proofing detection rod blocks the wrong nut, thereby preventing the wrong nut from entering the nut feeding guide. When there are multiple nuts with similar appearance but different widths on the production line, the problem of nuts of the wrong width being easily mixed into the nut feeding guide can be solved in a low-cost and easy-to-operate way.

According to the structural characteristics of the hexagonal nut, the error-proofing guide plate is designed to have an inclined surface on one side and an arc surface on the other side by means of the pressure when the nut is pressed by hand and the weight of the nut itself.

The connecting rod applies pressure to the nut through bolts and springs to press the nut against the error-proofing baffle, and the newly fed nut above can easily push the correct nut down to the discharging area of ​​the nut error-proofing base and fall into the nut feeding guide rail; if the wrong nut is placed, the diagonal width e2 of the wrong nut is less than the inner diameter r of the circular groove of the error-proofing detection rod, and the connecting rod automatically extends the error-proofing detection rod due to elastic force through bolts and springs, and the wrong nut is stuck in the circular groove, so that the nut can no longer be pressed from above to enter the feeding area of ​​the nut error-proofing base, thereby realizing the function of preventing nuts with small width from entering the discharging area of ​​the nut error-proofing base.

[0038] According to the width h of the anti-error guide plate ≈ & > the opposite width s1 of the correct nut and the inner diameter r of the circular groove of the anti-error detection rod ≈ & < the diagonal width e1 of the correct nut, the width h of the anti-error guide plate and the inner diameter r of the circular groove of the anti-error detection rod are designed to prevent nuts of incorrect width from entering the nut feeding guide rail.
