Detailed implementation manners

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides as Figures 1-5An automatic capping mechanism for the threaded end of steel bars shown in the figure includes a support frame 1 and a cap sorting machine 2. The cap sorting machine 2 is located at the top of one side of the support frame 1. A vibrator 3 is installed at the top of one side of the support frame 1, and the vibrator 3 is located at the bottom of the output line of the cap sorting machine 2. The cap sorting machine 2 straightens the protective caps for the threaded ends, and then transports the protective caps for the threaded ends to the designated position through the vibration of the vibrator 3. A forward and backward cylinder 4 and a first sliding plate are installed at the top of one side of the support frame 1, and the output end of the forward and backward cylinder 4 is connected to the first sliding plate. A left and right moving cylinder 5 and a second sliding plate are installed on the top of the first sliding plate, and the output end of the left and right moving cylinder 5 is connected to the second sliding plate. A cap positioning cylinder 6 is installed at the top of one side of the second sliding plate, and an L-shaped positioning frame is fixedly connected to the output end of the positioning cylinder 6. A cap grasping mechanism is fixedly installed on the outer wall of the top of one side of the first sliding plate. When the left and right moving cylinder 4 moves to the left, the cap grasping mechanism is moved to the position of the protective cap for the threaded end. The cap grasping mechanism includes a three-axis lifting cylinder 7, a rotary cylinder 8 and a cap clamping cylinder 9. The three-axis lifting cylinder 7 is fixedly installed on the outer wall of the top of one side of the first sliding plate, the rotary cylinder 8 is fixedly installed on the side wall of the top of the three-axis lifting cylinder 7, and the cap clamping cylinder 9 is connected to the output end of the rotary cylinder 8. After the protective cap for the threaded end is accurately positioned by the cap positioning cylinder 6, the left and right moving cylinder 5 moves to the right to reset and drives the second sliding plate to move. The second sliding plate drives the protective cap for the threaded end to move by friction until it contacts the L-shaped positioning frame, so that the protective cap for the threaded end is located directly below the cap clamping cylinder 9. The three-axis lifting cylinder 7 drives the cap clamping cylinder 9 to descend and then clamps the protective cap for the threaded sleeve. Then the three-axis lifting cylinder 7 ascends, and the rotary cylinder 8 rotates 90°. A steel bar positioning cylinder 10 is installed at the lower part of one side of the support frame 1, and a positioning baffle is connected to the output end of the steel bar positioning cylinder 10. A steel bar clamp 11 and a power assembly 14 are arranged at the top of one side of the support frame 1, and the output end of the power assembly 14 is connected to the steel bar clamp 11. After the steel bar positioning cylinder 10 ascends to position the steel bar, the power assembly 14 drives the steel bar clamp 11 to clamp the steel bar. After the steel bar positioning cylinder 10 drives the positioning baffle to descend and get ready, the forward and backward cylinder 4 drives the grasped and rotated cap grasping mechanism to move forward, and accurately fits the protective cap for the threaded end onto the threaded end of the steel bar. The degree of automation is high, which greatly improves the work efficiency and reduces the labor cost.

[0023] In this embodiment, a knocking block 12 is connected to the output end of the rotary cylinder 8, and the knocking block 12 is perpendicular to the cap clamping cylinder 9. When the protective cap for the threaded end is not tightly fitted and is loose, through program control, the forward and backward cylinder 4 retreats, the rotary cylinder 8 drives the knocking block 12 to rotate to one side of the threaded end of the steel bar, and the forward and backward cylinder 4 moves forward for the second time, and the knocking block 12 knocks the protective cap for the threaded end tightly.

[0024] In this embodiment, an auxiliary cap assembly 13 is provided above the steel bar clamp 11. The auxiliary cap assembly 13 includes an auxiliary bracket 131, an auxiliary cylinder 132 and a striking plate 133. The auxiliary bracket 131 is fixedly installed on the top of one side of the support frame 1. The auxiliary cylinder 132 is fixedly installed on the top of the auxiliary bracket 131. The striking plate 133 is connected to the auxiliary bracket 131 through a rotating shaft. The output end of the auxiliary cylinder 132 is hinged to the striking plate 133. The striking plate 133 is in an "L" shape. When the thread head protection cap is not tightened or loose, through program control, the auxiliary cylinder 132 drives the striking plate 133 to rotate, and one end of the striking plate 133 can further tighten the thread head protection cap.

[0025] In this embodiment, the power assembly 14 includes a power cylinder 141, a toothed plate 142, a fixed frame 143, a bidirectional screw 144 and a gear 145. The power cylinder 141 is vertically installed at the lower part of the support frame 1. The toothed plate 142 is fixedly connected to the output end of the power cylinder 141. The fixed frame 143 is fixedly installed on the top of the support frame 1. The bidirectional screw 144 is installed on the fixed frame 143 through a bearing. A gear 145 is welded on the side wall of one end of the bidirectional screw 144, and the gear 145 is meshed with the toothed plate 142. The bidirectional screw 144 is threadedly connected to the steel bar clamp 11. When it is necessary to fix the thread head of the threaded steel bar, the power cylinder 141 is started to drive the toothed plate 142 to move up and down, thereby driving the gear 145 to rotate, driving the bidirectional screw 144 to rotate, and the bidirectional screw 144 drives the steel bar clamps 11 on both sides to move towards each other, so as to clamp the thread head of the threaded steel bar.

[0026] In this embodiment, a rubber pad is provided on the side wall of the end of the striking block 12 away from the rotating cylinder 8, which can prevent knocking marks from being left on the thread head protection cap.

[0027] In this embodiment, a protective housing 15 is provided on the top of the support frame 1, which can better prevent dust from falling into the interior when not in use.

[0028] Working principle of the present utility model: The present invention is an automatic capping mechanism for reinforcing bar thread heads. First, the capping aligning machine 2 aligns the thread head protection caps. Then, through the vibration of the vibrator 3, the thread head protection caps are transported to the designated position. The left-right moving cylinder 4 moves left to move the cap grasping mechanism to the position of the thread head protection cap. After accurately positioning the thread head protection cap through the cap positioning cylinder 6, the left-right moving cylinder 5 moves right to reset. The three-axis lifting cylinder 7 drives the cap clamping cylinder 9 to descend and then clamps the thread sleeve protection cap. Then, the three-axis lifting cylinder 7 ascends. After the rotating cylinder 8 rotates 90°, at the same time, the reinforcing bar positioning cylinder 10 ascends to position the reinforcing bar and then the reinforcing bar clamp 11 clamps the reinforcing bar. After the reinforcing bar positioning cylinder 10 drives the positioning baffle to descend and get ready, the forward-backward cylinder 4 drives the grasped and rotated cap grasping mechanism forward to accurately fit the thread head protection cap onto the threaded reinforcing bar head. To prevent the situation that the thread head protection cap is not tightly fitted or loosened, through program control, the forward-backward cylinder 4 retreats and the rotating cylinder 8 drives the knocking block 12 to rotate to one side of the threaded reinforcing bar head. The forward-backward cylinder 4 advances for the second time, and the knocking block 12 knocks the thread head protection cap tightly.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
