DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-Figure 4 A one-time forming device for chamfering and thread rolling a large tail guide bolt comprises a base 1, a mounting seat 2 is fixedly mounted on the left end of the upper surface of the base 1, a control device is arranged inside the mounting seat 2, and the control device comprises a first motor 3, a first control rod 4, a movable clamping plate 5 and a movable tooth plate 6. When the first motor 3 is started, the rotating shaft drives the first control rod 4 to rotate, and when the first control rod 4 rotates, the movable clamping plate 5 is controlled to move horizontally, and the movable clamping plate 5 drives the movable tooth plate 6 to move.

[0019] like Figure 3 As shown, the first motor 3 is fixedly mounted inside the mounting base 2, the first control rod 4 is fixedly connected to the rotating shaft of the first motor 3, a card slot 21 is opened inside the mounting base 2, the movable card plate 5 is slidably inserted into the inside of the card slot 21, and the outer surface of the first control rod 4 is connected with the internal thread of the movable card plate 5. When the first motor 3 is started, the rotating shaft drives the first control rod 4 to rotate, thereby controlling the movable card plate 5 to move horizontally and linearly in the card slot 21.

[0020] like Figure 4 As shown, the movable tooth plate 6 is slidably connected to the outer surface of the mounting seat 2, the outer surface of the movable clamping plate 5 is fixedly connected to the outer surface of the movable tooth plate 6, the upper surface of the base 1 is fixedly installed with a fixed tooth plate 11, the fixed tooth plate 11 is located directly below the movable tooth plate 6, the lower surface of the movable tooth plate 6 is fixedly installed with an inclined block 61, and the right side surface of the fixed tooth plate 11 is fixedly installed with an inclined plate 12. The movable clamping plate 5 drives the movable pressure plate to move, and the movable clamping plate 5 is stuck in the clamping groove 21 to ensure that the movable tooth plate 6 can always move close to the outer surface of the mounting seat 2, and the inclined block 61 can limit the workpiece 111 to ensure that the workpiece 111 rotates along the surface of the inclined block 61 when the movable pressure plate moves to complete the processing.

[0021] like Figure 2As shown, a fixing seat 13 is fixedly installed on the right end of the upper surface of the base 1, a second motor 14 is fixedly installed inside the fixing seat 13, a second control rod 15 is fixedly installed on the rotating shaft of the second motor 14, a slide groove 16 is opened inside the fixing seat 13, when the second motor 14 is started, the rotating shaft drives the second control rod 15 to rotate, and the slide groove 16 facilitates the sliding plate 17 to slide in the fixing seat 13.

[0022] like Figure 2 As shown, a sliding plate 17 is inserted into the inner part of the slide groove 16 for sliding movement. The inner part of the sliding plate 17 is threadedly connected to the outer surface of the second control rod 15. A limiting plate 18 is fixedly installed on the front end surface of the sliding plate 17. A limiting groove 19 is provided on the upper end of the inner surface of the fixed seat 13. When the second control rod 15 rotates, the sliding plate 17 is controlled to slide horizontally. The limiting plate 18 is stuck in the limiting groove 19 and slides, thereby limiting the moving distance of the sliding plate 17.

[0023] like Figure 1 and Figure 2 As shown, the upper surface of the limit plate 18 is slidably connected to the inner wall of the limit groove 19, and the inner wall of the fixed seat 13 is located on the side of the limit groove 19 and fixedly installed with a stop switch 110. The stop switch 110 is electrically connected to the second motor 14 through a wire. A processing piece 111 is rotatably connected between the movable tooth plate 6 and the fixed tooth plate 11, and the rear end surface of the processing piece 111 contacts the outer surface of the limit plate 18. The upper surface of the base 1 is located below the fixed seat 13 and fixedly installed with a fixed plate 112. The right side surface of the fixed plate 112 contacts the outer surface of the processing piece 111. When the sliding plate 17 moves to the left, the limit plate 18 will squeeze the stop switch 110, so that the stop switch 110 controls the second motor 14 to stop, and the movable tooth plate 6 and the fixed tooth plate 11 clamp the processing piece 111 in the middle for thread rolling.

[0024] By setting a control device, when the workpiece 111 is subjected to thread rolling and forming, the workpiece 111 is placed on the inclined plate 12, and then the first motor 3 is started, the rotating shaft drives the first control rod 4 to rotate, and the movable clamping plate 5 is controlled to drive the movable tooth plate 6 to move back and forth left and right, so that the inclined block 61 brings the workpiece 111 between the movable tooth plate 6 and the fixed tooth plate 11. As the movable tooth plate 6 continues to move, the workpiece 111 is subjected to thread rolling and forming. When the workpiece 111 is limited, the second motor 14 is started, the rotating shaft drives the second control rod 15 to rotate, and the sliding plate 17 is controlled to slide horizontally, so that the limit plate 18 squeezes the rear end of the workpiece 111 until the limit plate 18 squeezes the stop switch 110, and the second motor 14 is controlled to stop, so as to ensure that the workpiece 111 remains in a fixed position. When a workpiece 111 is completed, there is no need to adjust the position of the limit plate 18. The workpiece 111 can be placed against the surface of the inclined plate 12 and the limit plate 18, thereby achieving the effect of ensuring continuity and convenient use during bolt thread rolling and forming.

[0025] Working principle: When the workpiece 111 is subjected to thread rolling and forming, the workpiece 111 is placed on the inclined plate 12, and then the first motor 3 is started, the rotating shaft drives the first control rod 4 to rotate, the movable clamping plate 5 is controlled to drive the movable tooth plate 6 to move back and forth left and right, and the inclined block 61 brings the workpiece 111 between the movable tooth plate 6 and the fixed tooth plate 11. As the movable tooth plate 6 continues to move, the workpiece 111 is subjected to thread rolling and forming. When the workpiece 111 is limited, the second motor 14 is started, the rotating shaft drives the second control rod 15 to rotate, the sliding plate 17 is controlled to slide horizontally, and the limit plate 18 squeezes the rear end of the workpiece 111 until the limit plate 18 squeezes the stop switch 110, and the second motor 14 is controlled to stop to ensure that the workpiece 111 remains in a fixed position. When a workpiece 111 is completed, there is no need to adjust the position of the limit plate 18, and the workpiece 111 can be placed against the surface of the inclined plate 12 and the limit plate 18.
