Abstract
The utility model discloses a pad penetration error prevention device for a thread rolling machine. The device comprises an automatic pad penetration device (1) and a guide rail (2) which is arranged on a frame and on which a workpiece travels, wherein the guide rail (2) extends to a thread rolling part (3) from the automatic pad penetration device (1); an error detection device (4) is arranged on the guide rail (2) between the automatic pad penetration device (1) and the thread rolling part (3) and comprises a pressing plate (41); the pressing plate (41) covers the guide rail (2) at a corresponding position; and the distance (h) from the upper surface of the guide rail (2) to the lower surface of the pressing plate (41) is greater than the thickness (S) of a workpiece nut and is slightly less than or equal to the sum of the thickness (S) of the workpiece nut and the thickness (P) of a gasket (6). The device has the advantages that: the error detection device is arranged on the guide rail, so a screw on which the gasket is not sleeved can be automatically separated from the error detection device on the guide rail before thread rolling of the screw if the gasket is not sleeved on the screw before the thread rolling of the screw, and the rejection ratio of the product is effectively reduced.
Description
Technical field
The utility model relates to a kind of thread rolling machine technical field, refers to that especially a kind of thread rolling machine wears the pad error prevention device.
Background technology
Existing a kind of patent No. discloses a kind of structure for the Chinese utility model patent that the CN98217653.8 name is called " thread rolling machine automatic feed mechanism ", and its structure is taken turns and driven their rotating drive dish I and drive dish II etc. by the control of frame, hopper, tipping bucket plate, hopper guide rail, the moving runner of realizing feeding, realization order guide and forms.The continuous revolution that this utility model is utilized moving runner sweeps workpiece to be conveyed into the hopper guide rail and freely to glide and runs to thread rolling machine and realize the self-feeding purpose.It is simple in structure, low cost of manufacture, and feeding speed is fast, and noise is low, long service life, a people can carry out many operations, and high efficiency is saved the labour, does not need the additional power device.But its shortcoming is that error prevention device is not set on the guide rail, if bolt pad before thread rolling is not placed on the bolt like this, band pad bolt can occurs and lack the pad phenomenon, causes this product rejection, so its structure awaits to improve.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Extremely shown in Figure 8 as Fig. 1, the thread rolling machine of present embodiment is worn the pad error prevention device, include the guide rail 2 of wearing cushion device 1 automatically and being installed on workpiece walking on the frame, guide rail 2 is positioned at the low or lower slightly structure of thread rolling portion 3 one ends to wear cushion device 1 one ends height automatically and extends to thread rolling portion 3 obliquely from wearing cushion device 1 automatically.Automatically the guide rail of wearing between cushion device 1 and the thread rolling portion 32 is provided with Error Detection Unit 4, this Error Detection Unit 4 includes pressing plate 41, described pressing plate 41 is covered in guide rail 2 tops of relevant position, this pressing plate 41 is slightly less than for the distance greater than workpiece nut thickness S or equals the distance that workpiece nut thickness S adds Upper gasket 6 thickness P, i.e. distance＜h of nut thickness S≤{ nut S+ spacer thickness d} from upper surface to the distance h between pressing plate 41 lower surfaces of guide rail 2.Have groove 21 on the guide rail below the pressing plate 41 2, this groove 21 is circumscribed circle diameter d more than or equal to workpiece nut 5 along the openend of guide rail 2 directions apart from m.And the distance L between the guide rail medial surface 23 on this recess sidewall 22 and opposite is the circumscribed circle diameter d more than or equal to workpiece nut 5.The middle part of pressing plate 41 has mounting hole 40, and this pressing plate 41 is spirally connected and fixed with each other through the screw 45 of mounting hole 40 and a fixed head 42 end faces by screw 44 or bolt, and the bottom of described fixed head 42 and guide rail 2 lateral surfaces are fixed together.On fixed head 42, have the vertical mounting hole 46 that can make fixed head 42 upper and lower displacements and adjust distance, and fixed head 42 and guide rail 2 is fixed with each other by screw 47 through vertical mounting hole 46.In order to strengthen guide rail intensity, present embodiment is equipped with liner plate 43 between fixed head 42 and guide rail 2.The cushion device of wearing automatically in the above-mentioned thread rolling is quite ripe prior art, and here no longer carefully states, and particular content can be known from network.
Operation principle of the present utility model is, screw or bolt from the guide rail of wearing cushion device automatically to the moving process of thread rolling portion, when passing Error Detection Unit, be slightly less than or equal the distance that workpiece nut thickness S adds Upper gasket 6 thickness P, that is: distance＜h of nut thickness S≤{ nut S+ spacer thickness d} owing to pressing plate 41 is designed to distance greater than workpiece nut thickness S from upper surface to the distance h between pressing plate 41 lower surfaces of guide rail 2.When the screw that places pad when the pressing plate, the nut of screw upper end and the mutual holding of pressing plate bottom surface and form support force, thus under the promotion of rear portion screw, can pass leak detection portion automatically.If screw is through leak detection portion the time, when not being coated with pad, differ the thickness of a pad at this moment between the nut of screw upper end and the pressing plate bottom surface, thereby can not form card power between the nut of pressing plate and screw upper end, screw banking falls down because of the effect meeting of gravity, and drop out automatically from the leak detection subordinate side of guide rail, promptly from guide rail, isolate automatically, thereby realize the purpose of leak detection automatically.
