DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] The following is a detailed description of the embodiments of the present utility model. These embodiments are implemented on the premise of the technical solution of the present utility model, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present utility model is not limited to the following embodiments.
[0027] Referring to Figures 1 to 7 , this embodiment discloses an automatic assembling mechanism for the hopper of a hoist. The hopper 1 of the hoist is composed of a U-shaped main board 2 and end plates 3 located inside the U-shaped main board 2 and near the front and rear ends of the U-shaped main board 2. The automatic assembling mechanism includes: a set of fixed U-shaped profiling positioning tools 4 fixed on a base 5; two sets of movable U-shaped profiling positioning tools 6 movably installed on the base 5 and symmetrically distributed on the front and rear sides of the fixed U-shaped profiling positioning tool 4. The two sets of movable U-shaped profiling positioning tools 6 are driven by a first driving mechanism to move in the front-rear direction in opposite directions, so as to make the two sets of movable U-shaped profiling positioning tools 6 approach or move away from the fixed U-shaped profiling positioning tool 4 in the middle at the same time, so as to meet the placement requirements of the U-shaped main boards 2 with different lengths of hoppers 1 of different models.
[0028] The first driving mechanism includes a driving gear 7 and two racks 8. The driving gear 7 is rotatably installed on the base 5 and driven to rotate by a driving motor. The two racks 8 are arranged on the left and right sides of the driving gear 7 and respectively mesh with the driving gear 7. Two first guide rails 9 are fixedly provided on the base 5. Each rack 8 and each first guide rail 9 extend in the front-rear direction. The two racks 8 are respectively slidably matched with the two first guide rails 9 through first sliders 10. The positioning bases 16 of the two sets of movable U-shaped profiling positioning tools 6 are respectively fixedly installed on the two racks 8.
[0029] Among them, each set of U-shaped profiling positioning tooling includes a fixed positioning frame 11 and a movable positioning frame 12 arranged opposite to each other on the left and right. The fixed positioning profile 13 on the inner side of the fixed positioning frame 11 and the movable positioning profile 14 on the inner side of the movable positioning frame 12 respectively coincide with the side shapes of the left and right sides of the U-shaped main board 2. Magnet blocks 15 for magnetically adsorbing the U-shaped main board 2 are respectively arranged on the fixed positioning profile 13 of the fixed positioning frame 11 and the movable positioning profile 14 of the movable positioning frame 12. The fixed positioning frame 11 is fixedly installed on the positioning base 16, the movable positioning frame 12 is movably installed on the positioning base 16, a second slider 17 is provided at the bottom of the movable positioning frame 12, and the positioning base 16 is provided with a second guide rail 18 that is slidably matched with the second slider 17 and extends in the left-right direction; the movable positioning frame 12 is driven by a second driving mechanism to move along the left-right direction of the positioning base 16, so as to adjust the distance between the fixed positioning frame 11 and the movable positioning frame 12. The second driving mechanism includes a driving cylinder 19, and the movable positioning frame 12 is driven by the driving cylinder 19 to move along the left-right direction of the positioning base 16. During use, the distance between the movable positioning frame 12 and the fixed positioning frame 11 can be adjusted as needed to adapt to the angle change caused by the springback deformation of the U-shaped main board 2 formed by bending.
[0030] A clamping mechanism for clamping the U-shaped main board 2 is provided on each positioning frame. The clamping mechanism includes a clamping cylinder 20 arranged on the outer side of the corresponding positioning frame. An L-shaped clamping block 21 is provided on the rocker arm of the clamping cylinder 20. The rocker arm and the clamping block 21 thereon are driven by the clamping cylinder 20 to flip, so as to clamp or release the U-shaped main board 2 located inside the positioning frame.
[0031] In each set of movable U-shaped profiling positioning tooling 6, positioning stoppers 22 are respectively provided on the sides of the fixed positioning frame 11 and the movable positioning frame 12 away from the fixed U-shaped profiling positioning tooling 4. The positioning stopper 22 is composed of a blocking section 23 and a positioning section 24 in an L shape. The blocking section 23 of the positioning stopper 22 extends in the left-right direction and is fixed on the corresponding positioning frame. The positioning section 24 of the positioning stopper 22 extends in the front-back direction, and the positioning section 24 of the positioning stopper 22 is located inside the positioning profile of the corresponding positioning frame. The gap between the positioning section 24 of the positioning stopper 22 and the positioning profile of the corresponding positioning frame forms an insertion gap for the front end or the rear end of the U-shaped main board 2 to be inserted. The positioning section 24 of the positioning stopper 22 forms a positioning end 25 for positioning the end plate 3 at one end facing the fixed U-shaped profiling positioning tooling 4.
[0032] During operation, first, according to the model of the hopper 1 to be assembled, adjust the front-back distance between the two sets of movable U-shaped profiling positioning toolings 6 so that the U-shaped main board 2 of the hopper 1 to be assembled can just be placed on the three sets of U-shaped profiling positioning toolings. At the same time, by controlling the driving cylinder 19, pull the movable positioning frame 12 and the fixed positioning frame 11 apart by a certain distance to facilitate the smooth placement of the U-shaped main board 2 deformed by springback after bending. After adjustment, place the U-shaped main board 2 on the three sets of U-shaped profiling positioning toolings. The U-shaped main board 2 is placed in the placement gap between the fixed positioning frame 11 and the movable positioning frame 12 of each set of U-shaped profiling positioning toolings, and the side surfaces on the left and right sides of the U-shaped main board 2 are basically in contact with the fixed positioning surface 13 on the inner side of the fixed positioning frame 11 and the movable positioning surface 14 on the inner side of the movable positioning frame 12, and the U-shaped main board 2 is preliminarily adsorbed on the left and right sides by the magnet blocks 15. Then, the driving motor of the first driving mechanism is started to drive the driving gear 7 to rotate. The driving gear 7 drives the two racks 8 to move in the reverse direction along the front-back direction, thereby driving the two sets of movable U-shaped profiling positioning toolings 6 to approach the center at the same time. During this process, the front and rear ends of the U-shaped main board 2 are gradually inserted into the insertion gaps of the two sets of movable U-shaped profiling positioning toolings 6, that is, the positioning section 24 of the positioning block 22 gradually extends into the inner side of the U-shaped main board 2 until the front and rear ends of the U-shaped main board 2 respectively contact and resist against the blocking sections 23 of the positioning blocks 22 of the two sets of movable U-shaped profiling positioning toolings 6. At this time, the driving motor stops, and the two sets of movable U-shaped profiling positioning toolings 6 move into place. Then, the clamping mechanisms on each positioning frame act to drive the clamping blocks 21 to flip to clamp the U-shaped main board 2 located inside the positioning frame. Then, put the two end plates 3 of the hopper 1 to be assembled in. The positioning ends 25 of the positioning sections 24 of the positioning blocks 22 of the two sets of movable U-shaped profiling positioning toolings 6 accurately position the put-in end plates 3, that is, the assembly of the two end plates 3 is completed. After that, start the driving cylinder 19 again to drive the movable positioning frame 12 to move towards the fixed positioning frame 11, so that the U-shaped main board 2 is tightened and the edges of the end plates 3 are closely attached to the inner side of the U-shaped main board 2, that is, the assembly process is completed. Then, carry out the welding operation between the end plates 3 and the U-shaped main board 2. Due to the clamping of the clamping mechanism and the magnetic attraction of the magnet blocks 15, the displacement of the two during the welding process is avoided, ensuring the smooth and stable progress of the welding process, and improving the welding efficiency and welding quality.
[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
