Preferably, the insulating plate 4 is further provided with a counting probe 6, the counting probe 6 is downward and corresponds to a thread rolling station between the fixed thread rolling plate 1 and the movable thread rolling plate 9, and the detecting end of the counting probe 6 is the same as the top end of the bolt embryo 10 in height.

Preferably, the detecting probe 5 faces the feeding side of the thread rolling station, and the counting probe 6 faces the discharging side of the thread rolling station.

Preferably, the detection height of the detection probe 5 is 0.5mm above the bolt blank 10.

Compared with the prior art, the utility model has the advantages that:

when the floating phenomenon occurs on the bolt embryo 10 on the thread rolling machine, the bolt embryo 10 contacts with the detection probe, so that the bolt embryo 10 with the floating condition can be timely found, the thread rolling machine stops working and alarms, and the labor cost is saved;

the position of the detection probe can be adjusted through the lead screw guide rail so as to adapt to detection of screw products with different specifications, and the adaptability of the device is improved;

through the counting probe, the number of qualified screw products produced after the production is finished can be directly obtained, the subsequent procedure of manually determining the number of products is omitted, and the labor cost is reduced.

Detailed Description

Example 1

The thread detection mechanism of the thread rolling machine comprises a fixed thread rolling plate 1 and a movable thread rolling plate 9, wherein the fixed thread rolling plate 1 and the movable thread rolling plate 9 are arranged on the thread rolling machine, a thread rolling station is arranged between the fixed thread rolling plate 1 and the movable thread rolling plate 9, a vertical lead screw guide rail 2 is arranged on the fixed thread rolling plate 1, the lead screw guide rail 2 is arranged on a frame of the thread rolling machine, a horizontal lead screw guide rail 3 is arranged on a sliding table of the vertical lead screw guide rail 2, the lead screw guide rail 3 can integrally move along the sliding table of the lead screw guide rail 2 in the vertical direction, an insulating plate 4 is arranged on the sliding table of the lead screw guide rail 3, the insulating plate 4 can move along the sliding table of the lead screw guide rail 3 in the horizontal direction, a detection probe 5 is arranged on the insulating plate 4, the detection probe 5 is downwards arranged and corresponds to the thread rolling station between the fixed thread rolling plate 1 and the movable thread rolling plate 9, the detection probe 5 is positioned above a bolt embryo 10 by 0.5mm, and the detection probe 5 is a contact type sensor and is electrically connected with a control system of the thread rolling machine through a lead wire 7.

In the working process of the embodiment, the bolt embryo 10 enters a thread rolling station, the movable thread rolling plate 9 reciprocates relative to the fixed thread rolling plate 1, one bolt is machined after each reciprocation of the movable thread rolling plate 9, the bolt embryo 10 moves along with the movable thread rolling plate 9 from the feeding side to the discharging side of the thread rolling station, the bolt embryo 10 is not contacted with the detection probe 5 in normal machining, when the bolt embryo 10 floats when entering the thread rolling station, the bolt embryo 10 contacts with the detection probe 5, the detection probe 5 sends a signal to a control system of the thread rolling machine, the thread rolling machine stops and alarms, unqualified products are detected, and when the specifications of the bolt embryo 10 to be machined are different, the detection probe 5 can move in the horizontal direction and the vertical direction by adjusting the sliding tables on the screw guide rails 2 and 3, so that the detection probe 5 can adapt to detection of the bolt embryos 10 with different specifications.
