Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution:

example (b):

as shown in fig. 1-3, an automatic turning and positioning device for a steel structural member comprises a turning assembly 1 and a fixing assembly 2 for fixing a workpiece;

the overturning assembly 1 comprises a connecting seat 3 and two overturning arms 4, one ends of the two overturning arms 4 are hinged with the connecting seat 3, the other ends of the overturning arms 4 are hinged with one ends of driving pieces 5 for driving the overturning arms 4 to rotate around hinged points on the connecting seat 3, and the other ends of the driving pieces 5 are hinged with the connecting seat 3; the top surfaces of the two turnover arms 4 form a working plane for supporting a workpiece;

the fixed component 2 is arranged on a fixed table 6, and the top surface of the fixed table 6 is flush with the working plane.

The driving piece 5 is a cylinder or an oil cylinder. Wherein, the hinge point of the turning arm 4 and the connecting seat 3 is positioned above the hinge point of the driving part 5 and the connecting seat 3.

The working principle is as follows: the workpiece (I-steel) is placed on the working plane and fixed by the fixing assembly. The workpiece is supported by the work plane and the fixed table 6. When one surface of the workpiece is machined, the turnover surface is turned over (when the workpiece is not turned over, the two turnover arms 4 are horizontal, and the working plane is a horizontal plane). When the workpiece is turned over, the fixing component loosens the workpiece.

The turning process is as follows: the driving member 5 drives one of the turnover arms 4 to rotate to the vertical (or inclined) state, so that the turnover arm 4 rotates to be close to the workpiece. Then the other turnover arm 4 with the workpiece is driven to rotate, when the turnover arm 4 with the workpiece rotates, the workpiece synchronously rotates to a certain angle, and the workpiece is turned over to the vertical (or inclined) turnover arm 4 under the action of gravity. At the moment, the two turnover arms 4 are restored to the initial state, and then the surface changing of the workpiece can be completed.

The workpiece is turned over through the turning arm 4, so that manual turning is avoided, the labor intensity of workers is reduced, and potential safety hazards are avoided.

Further, as shown in fig. 2, the connecting seat 3 is disposed on a supporting frame 7, a screw slider mechanism 8 is disposed on the supporting frame 7, and the connecting seat 3 is disposed on a slider 9 of the screw slider mechanism 8.

When the workpiece is turned or after the workpiece is turned, the screw slider mechanism 8 drives the connecting seat 3 to move, and when the connecting seat 3 moves, the supporting arm on the connecting seat moves synchronously, so that the workpiece is driven to the middle part of the fixed table 6. When the workpiece is large, the workpiece can be prevented from falling out of the fixed table 6 due to turnover.

Further, as shown in fig. 1 to 3, a sliding groove 10 is provided on the fixed table 6 along the length direction thereof, the fixed assembly includes two clamping blocks 11, a first lead screw 12, a second lead screw 13 and a limit rod 14, the first lead screw 12, the limit rod 14 and the second lead screw 13 are sequentially and parallelly disposed in the fixed table 6, the first lead screw 12 is provided with a first sliding block 15 adapted thereto, the first sliding block 15 is slidably connected with the limit rod 14, the second lead screw 13 is provided with a second sliding block 16 adapted thereto, the second sliding block 16 is slidably connected with the limit rod 14, and the first sliding block 15 and the second sliding block 16 are respectively disposed at two ends of the limit rod 14;

one of the clamping blocks 11 is connected with a first sliding block 15, the other clamping block 11 is connected with a second sliding block 16, and both clamping blocks 11 extend out of the fixed table 6 through the sliding grooves 10. The limiting rod 14 is arranged between the first lead screw 12 and the second lead screw 13, the first lead screw 12 and the second lead screw 13 are driven by two motors respectively, and the first lead screw 12 and the second lead screw 13 are rotatably connected with the bearing seat fixing table 6 respectively.

The clamping mechanism of the two clamping blocks can be, but is not limited to, one of the clamping blocks stops after moving a fixed distance, and the other clamping block moves until the moment of the other clamping block reaches the clamping moment stop (such as 100N).

The first lead screw 12 and the second lead screw 13 respectively drive the first sliding block 15 and the second sliding block 16 to move towards the directions close to each other, so that the workpiece is clamped tightly, and the workpiece displacement during rivet welding is avoided. Wherein the gag lever post 14 acts as a guide.

Further, as shown in fig. 1-3, a horizontal roller 17 is arranged between the fixing component and the overturning component 1, and the highest point of the roller 17 is flush with the top surface of the fixing table 6. When the automatic overturning positioning device is used, one set of automatic overturning positioning device (two sets in total) can be arranged, and the two sets of automatic overturning positioning devices can support and overturn the large-sized workpiece. And the two sets of automatic overturning and positioning devices synchronously operate during overturning.

And two ends of the roller 17 are respectively connected with a jacking cylinder 18 through bearing seats. When the workpiece needs to be transported, the jacking cylinder jacks the roller to enable the roller to be higher than the working plane, the workpiece is supported by the two rollers, meanwhile, the workpiece is conveyed when the rollers rotate, the jacking cylinder resets after the workpiece is conveyed in place, and the workpiece is supported by the working plane again. The arranged roller is convenient for conveying workpieces. A baffle plate 19 is arranged on one side of the fixed station far away from the turnover assembly. One end of the baffle plate is connected with the cylinder, and the baffle plate can be retracted below the top surface of the fixed table when not in use, so that the influence of the baffle plate on the use of the fixed table is avoided. The arranged baffle plate can be positioned when the large-sized workpiece is conveyed, when the end part of the large-sized workpiece abuts against the baffle plate, the workpiece is conveyed in place, and the large-sized workpiece can be prevented from continuously advancing to run out of a preset position under the action of inertia.
