DETAILED DESCRIPTION
[0027] 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. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0028] Embodiment: An automatic loading and unloading mechanism for drilling holes in finished welded parts, such as Figure 1-Figure 8 As shown, it includes a frame 1, a guide plate 2, a support frame 3, a loading rack 8, an electric push rod 9, a support plate 10, a drilling machine 15, a limiting mechanism, a pushing mechanism and a feeding mechanism. The guide plates 2 are symmetrically fixedly connected to the front and rear sides of the frame 1, the support frame 3 is fixedly connected to the right side of the frame 1, the loading rack 8 is fixedly connected to the top of the support frame 3, the electric push rods 9 are symmetrically fixedly connected to the front and rear sides of the support frame 3, the support plate 10 is fixedly connected between the output shafts of the two electric push rods 9, a limiting assembly is provided on the left part of the guide plate 2, a pushing mechanism is provided in the middle part of the frame 1, a feeding mechanism is provided on the left side of the frame 1, and a drilling machine 15 is installed on the top of the guide plate 2. The drilling machine 15 is the prior art.
[0029] like Figure 2-Figure 4As shown, the limit assembly includes a limit block 4, a fixed column 5, a torsion spring 6 and a clamping column 7. A limit groove 201 is symmetrically opened in the middle of the guide plate 2. The grooves opened on the left parts of the two guide plates 2 are fixedly connected with fixed columns 5. The fixed columns 5 are rotatably connected to the limit blocks 4. Torsion springs 6 are wound around the fixed columns 5 on both sides of the limit block 4. A clamping column 7 is also fixedly connected to the inner wall of the groove on the left side of the limit block 4.
[0030] like Figure 1 and Figure 6 As shown, the pushing mechanism includes a driving motor 11, a first spur gear 12, a second spur gear 13 and a pushing member 14. The driving motor 11 is connected to the front side of the frame 1 by bolts, and the output shaft of the driving motor 11 passes through the outer wall of the frame 1 backward, and the first spur gear 12 is fixedly connected to the output shaft of the driving motor 11. The second spur gear 13 is rotatably connected to the inner wall of the front side of the frame 1, and another first spur gear 12 is also rotatably connected to the inner wall of the frame 1. The second spur gear 13 is located between the two first spur gears 12, and the two first spur gears 12 are meshed with the second spur gear 13. A pushing member 14 is rotatably connected between the eccentric positions on the rear sides of the two first spur gears 12. The pushing member 14 is located in the middle of the frame 1, and the highest position that the pushing member 14 can reach does not exceed the top of the weldment placed on the guide plate 2.
[0031] When using this device, first place this device on a flat ground, stack the welded parts to be processed into the carrier 8, then start the electric push rod 9, the telescopic rod of the electric push rod 9 extends and moves to the left, driving the support plate 10 to move to the left, because the support plate 10 and the welded parts are at the same horizontal height, and then push the lowest welded part to move to the left. When the electric push rod 9 drives the bottom welded part to move to the left, the upper welded parts slide down one by one, and the support plate 10 will block the welded parts, and the welded parts will not fall to the bottom. After the lowest welded part is pushed onto the guide plate 2, the telescopic rod of the electric push rod 9 will automatically move to the right and retract, and the support plate 10 no longer supports the welded parts in the carrier 8. The welded parts fall to the top of the support frame 3, waiting for the electric push rod 9 to push them onto the guide plate 2.
[0032] The welded part pushed onto the guide plate 2 is blocked by the limit assembly. After the drive motor 11 is started, the output shaft of the drive motor 11 drives the first spur gear 12 to rotate counterclockwise, thereby driving the second spur gear 13 meshing with it to move clockwise, and then drives the first spur gear 12 on the right side of the second spur gear 13 to move counterclockwise, driving the pusher 14 to move counterclockwise. When the pusher 14 moves counterclockwise, it pushes the welded part on the right side of the guide plate 2 to the left. The pusher 14 can be moved from top to bottom and from left to right due to the rotation of the first spur gear 12. The right one swings back and forth, pushing the weldment to move to the left. The left movement of the weldment will squeeze the limit block 4 downward, and the limit block 4 rotates counterclockwise. The torsion spring 6 wrapped around the fixed column 5 is deformed, and the limit block 4 no longer blocks the weldment. The weldment continues to move to the left. The limit block 4 plays the role of limiting the weldment to avoid deviation in the moving position when the weldment is pushed by the electric push rod 9. When the weldment moves away from the limit block 4, the limit block 4 is no longer squeezed, the torsion spring 6 is reset, driving the limit block 4 to rotate clockwise, and the clamping column 7 limits the limit block 4 from rotating to the initial position.
[0033] When the pushing member 14 drives the welding part to move to the middle limit groove 201, the pushing member 14 moves counterclockwise alone to separate from the welding part. During the gap of this movement, the drill bit moves downward to drill a hole in the welding part. After the drilling is completed, the pushing member 14 continues to drive the welding part to move to the left until it reaches the bracket 17.
[0034] like Figure 1 , Figure 7 and Figure 8 As shown, the unloading mechanism includes a bracket 17, a lifting cylinder 18, a pushing block 19, a holding box 20, a holding block 21, a torsion spring 22 and a blocking rod 23. The bracket 17 is fixedly connected to the left side of the frame 1, and the lifting cylinder 18 is installed on the left side of the top of the frame 1. The lifting cylinder 18 is located inside the bracket 17. A pushing block 19 is fixedly connected to the telescopic rod of the lifting cylinder 18. The pushing block 19 contains a magnet that can adsorb welded parts. A holding box 20 is installed on the top of the bracket 17 in a snap-on manner. The holding box 20 is rotatably connected to the left and right sides of the lower part, and a torsion spring 22 is connected between the two holding blocks 21 and the holding box 20. A blocking rod 23 for limiting the holding block 21 is fixedly connected to the lower part of the holding box 20.
[0035] When the welded part reaches the bracket 17, the lifting cylinder 18 starts to work, and the telescopic rod of the lifting cylinder 18 drives the pushing block 19 to move upward. Because the welded part is generally made of steel, the magnet in the pushing block 19 will be attracted to the welded part, and then push the welded part to move upward and be placed in the storage box 20. A limiting assembly is installed at the lower part of the storage box 20. When the welded part moves upward, it will squeeze the support block 21 to rotate, causing the torsion spring 22 to deform, and the support block 21 will no longer block the welded part. After the welded part continues to move upward and away from the support block 21, the torsion spring 22 resets, driving the support block 21 to reverse, and the blocking rod 23 limits the support block 21 from rotating to the initial position. At this time, the telescopic rod of the lifting cylinder 18 moves downward, and the protruding part of the support block 21 will jam the welded part, so that the welded part cannot continue to move downward and separate from the pushing block 19.
[0036] The device can complete the automatic loading and unloading movement of the finished welded parts by continuously repeating the above operations. When the tray 20 is full, it can be directly lifted and removed, and a new tray 20 can be replaced to continue the loading and unloading operation.
